Q

Just before delivery, strong uterine contractions leads to reduced placenta function.

  • Every normal vaginal delivery leads to hypoxemia.
  • The fetus has during the delivery SaO2 of 30-40%
    (down to 20 %).
    That´s why the heart rate is high: 110-160 bpm

Umbilical cord pH ~7.25 (7.15-7.35) is normal.

  • Mild acidosis is well tolerated
  • Pathological acidosis: pH < 7.00 (0,3-0,4 % of all newborn)
A

A newborn infant is always CYANOTIC right after birth!

May persist for 5-10 min in healthy infants.

Q

Asphyxia (greek); without pulse

Def. Asphyxia: Impaired gas exchange in a fetus/newborn infant leading to:

  • Hypoxia
  • Hypercapnia
  • Metabolic acidosis (lactacidosis)
  • Glycogen use

• The fetus has ”buffer capacity” and is able to compensate for acidosis around 15 min, thereafter
”big trouble”.

A

Perinatal asphyxia - causes:

Prenatal
1. Sub-chronic
– Placental insufficiency leading to growth restriction
– Redistribution of blood to brain and heart
2. Sub-acute
– Preeclampsia
3. Acute
– Placental abruption, shoulder dystocia, compressed cord etc.

Postnatal

  1. Prenatal asphyxia continues (80 % !)
  2. Congenital infection?
  3. Maternal drugs?
  4. Congenital malformation?

Q

How do we perceive the asphyxia?

Before/during birth:
• Less fetal activity
• Meconium-stained amniotic fluid
• Fetal tachycardia (even worse bradycardia….)
• Uniform late decelerations and/or “Silent pattern” (CTG)

After birth:
• Apgar-score 0-6 at 1 or 5 minutes
• No BREATHING effort within 30 sec
• No CRYING within 60 sec
• Initial bradycardia and floppy
• ”No signs of life”
A

Normal CTG

Baseline of fetal heart rate:
• 110 – 150 beats/min

Variability/accelerations:
• 5 – 25 beats/min
• ≥ 2 accelerations/60 min

Variability/accelerations:
• Uniform, early decelerations
• Variable, uncomplicated decelerations
(amplitude < 60 beats)

Preterminal CTG: (Red flag!!!)
- No variability (< 2 beats/min) without accelerations regardless of decelerations / heart beat

Q

APGAR-score (0-10, der 10 er best, ønsket)

  • Appearance
  • Pulse
  • Grimace
  • Activity
  • Respiration
Observe:
1. Respiration
– Breathing /crying?
– Gasping/apnea?
2. Heart rate
– Evaluation only if child is not breathing adequately
– Listen to the heart, palpate the cord. 
3. Is the muscle tone good?

If these parameters are fine: Relax!

However, if the child is not breathing/crying or if the child is very floppy it might need:
A. Airway (and initial measures)
B. Breathing = ventilation
C. Circulation = chest compressions 
D. Drugs
  • 6-10 % of all newborn infants need some stimulation/ ”assistance” to initiate breathing after birth.
  • < 1 % need resuscitation.

Of 100 000 newborn in Sweden:
– 0,2 % (> 32 weeks) required unexpected resuscitation and 90% of these responded to mask ventilation alone.

CONCLUSION: Mask ventilation is essential

A

Skin color/complexion:

  • 0: blue or pale
  • 1: blue extremities, pink body
  • 2: no cyanosis :-)

Pulse rate:

  • 0: absent
  • 1: <100
  • 2: >100 :-)

Reflex irritability:

  • 0: no response to stimulation
  • 1: weak cry/grimace
  • 2: cry or pull away :-)

Muscle tone:

  • 0: none
  • 1: some flexion
  • 2: flexed arms and legs that resist extension :-)

Breathing:

  • 0: absent
  • 1: weak, irregular, gasping
  • 2: strong, lusty cry :-)

Initial measures
A) Stimulation
• Dry the baby warm with towels.
But don’t waist time with this if the baby is very sick!
• If the baby has established good spontaneous respiration and heart rate > 100 the situation is good :-)

B) Ventilation: mask cover mouth and nose.
Indicated if:
– Heart rate < 100/min in spite of stimulation or always when the baby has a very poor respiratory effort / is gasping.
– Always if very bradycardic and pale, start immediately.
• Suction?
– Not routinely. Too vigorous suctioning can cause bradycardia and delay the onset of respiration!
• Open airways, avoid/minimize leak around face mask
• Self expanding bags or Neopuff®
• Ventilation rate 30-60/min.
• Initiate ventilation with room air (21% O2) in neonatal resuscitation (term).

Open airway
- Head in neutral position

The primary measure of adequate initial ventilation is prompt improvement in heart rate.

C. Circulatory support = Chest compression
Heart rate < 60/min in spite of adequate ventilation for at least 60 s.
Ventilation most important and must be optimized before you start chest compressions
- Two thumb technique (+)
- Two finger technique
- Combined ventilation and chest compression
Chest compression 90/min - Ventilation 30/min
Ratio 3:1 (120 events/min)

D. Drugs
• Rarely need for drugs, if needed give drugs via umbilical vein
– Adrenaline (repeat every 3-5 min):
• IV: 20 (10-30) μg/kg = 0.2 ml K-adrenaline/kg
(Term: 0,5 ml)
– Volume (suspect hypovolemia or haemorrhage):
• NaCl 10-20 ml/kg over 10 min
• Blood transfusion (same volume)
– Buffer: rarely indicated
– Naloxone: Not routinely

Q

Acronym HELP

To help the doctor and the patient ensuring high quality of health care!!

  • History
  • Examination
  • Logical deduction
  • Plan for management
A
Examination - 1
Look (observation) first!
• Severity of illness
• Breathing
• Growth, nutrition
• Behaviour
• Hygiene, care

• Do NOT ask the child for permission, instead..
– Say friendly that
“I am now going to examine you”

Examination - 2
• The order of the exam can be individualized.
• Start by observation, introduce instruments and let the child check them out, keep invasive or painful parts for the end.
• Explain everything you will be doing
– Use age-appropriate, non-threatening terms
– Give feedback
• The child has to be undressed for the examination, but this can be done gradually and in stages.

Examination - 3
• General appearance!
– Observe
– Listen to history
• “The sick looking child”?
• Kids are impatient, so a systematic full examination may be difficult. Examine the most pertinent area first.
• Best examination method by age:
– Neonates, very young infants: on examination table.
– Up through preschool: lying/sitting on mother’s/father’s lap.
– Adolescent: sometimes without family present (ask what they want).
• Warm hands and warm the stethoscope!

Examination - 4
• Record respiratory rate FIRST, before crying starts.
– In child, breathing sounds are easier to hear, but hard to localize and hard to interpret.
• Auscultation of the heart early!
• Circulation
– Skin, capillary refill time!
• ENT (Ear, Nose & Throat) exam likely to induce a cry; goes last! Often most distressing.
• Opportunism (“use the chance you get”)
– If child dozes/sleeps – auscultate the heart.
– If child kicks examiner - observe hip range of motion.
– If cries - sometimes possible to inspect the throat.

Throat
Don’t use a spatula if you don’t need it!
Examination of the throat is best left as the last item of any examination as it is seldom comfortable.
It is much easier if the child willingly opens his mouth,
but if not, be firm, gentle, quick and careful.

Q

Severity of illness ”60 second assessment”

• Consciousness 
• Airway
– Effort, stridor, wheeze 
• Breathing
– Repiratory rate, cyanosis
• Circulation
– HR, pulse, peripheral temp, capillary refill time
A
Respiration - 1 
Important to assess:
• Respiratory rate!
• Chest wall recessions
• Inspiratory stridor?
• Expiratory grunting or wheezing?
• Ausculation
– Limitations in children!
Tachypnoea:
Neonate > 60
Infant > 50
Young children > 40 
Older children > 30 

Respiratory rate: Count before you use your stethoscope!!

Q

Abdomen

  • Inspection first
  • Palpation then
  • Flat hand
  • Hips flexed!
A

• Genital examination often routine in infants
– E.g. are testicles normally descended?
– Later only if relevant

• Rectal examination
– NOT part of routine
– Only if relevant

  • ‘Milk’ the testicle downwards towards the scrotum.
  • Do not feel from “the bottom” to see if the testicle
    is present, this will induce the cremasteric reflex and make it difficult for you to find the testicle.
  • Warm surroundings/bath tub.

Q

Brief neurological screen
• Parents account of developmental milestones.
• Adapt the neurological examination to the child age.
– Use common sense to avoid unnecessary examination
– Play, write
– Walk, run and jump!
– Language, vision, hearing (ask parents)
– Social interactions
• Usually not necessary with a “formal” neurological examination incl. reflexes, only in cases where you suspect neurological disease.

What is fever?
Rectal temperature > 38

• High fever (>40-40.5 oC) in children < 3-6 months is associated with a substantial risk of severe infection.
• Low threshold for admission!
BUT
• Children <3-6 months may be afebrile and still have a severe infection.
• Always consider the general condition as well !!

Investigations
• Complete blood count (CBC)
– Often high or very low WBC in severe bacterial infections
• CRP , procalcitonin
• Blood culture
• Urinary specimen
– Dip stick and culture
• Lumbar puncture
• Chest X-ray

RTI - etiology Children • Virus!!! • Bacteria (less frequent): Suspect when fever continues > 72 h! – Pneumococci (otitis, pneumonia) and Group A streptococci (tonsillitis) • Both almost uniformly susceptible to Penicillin in Norway. – Bordetella pertussi • Whooping cough; not completely protected by vaccination. – Mycoplasma, chlamydophila • Often, but not always, more severe clinical picture in children > 5 years. • May be self limiting or require treatment, MACROLIDE SpO2 < 92 % without oxygen is a serious condition
28
Otitis media • 80 % recover WITHOUT antibiotics within 2-3 days – Nose drops and Paracetamol • “Wait and see” prescription – Penicillin V • Antibiotics if: – < 1 year of age – Persistent high fever – Recurrent otitis
Throat infections Aetiology - Virus 90% - Streptococci (GAS) 10% Diagnostics - Strep A test - CRP, blood count? Treatment - Penicillin if streptococci
29
Infectious mononucleosis Incubation time: 30–50 d. EBV infects epithelia and B-lymphocytes in lymph nodes and spleen. Host response; CD8+ T-lymphocytes (activated lymphocytes, blood slide). Mainly symptomatic in adolescents. Often asymptomatic in small children. Possible complications - Airway obstruction - Spleen rupture (very rare) - Feeding problems - CNS (incl. encephalitis) - Hematology (ITP)
Acute laryngitis Spasmoid/viral croup (”falsk krupp”) Inspiratory stridor Barking cough - Diagnosed per phone.. Treatment: - Elevated head position, cold air - Nebulized adrenaline - P.o. Steroids DD: Epiglottitis (uncommon today)
30
Acute bronchiolitis - Affecting the small bronchioles • RS virus (RSV) and/or many other respiratory viruses (hMPV, adeno, influenza, rhino etc.) • “Winter” disease – Infants 1-12 months. • Children < 6 months and those with chronic underlying conditions are most severely affected. • Only 1 out of 100 infants with RSV infection are admitted to hospital. ``` Symptoms • Nasal congestion!! • Cough and fever +/- • Apnea (in the youngest) • Breathing difficulties!! ``` ``` Management • Oxygen via nasal prongs – Low flow or high flow with heated humidified gas • Give nasal spray/droplets! • Nebulized physiol. SALINE • Adrenaline (Norway) • CPAP • IV or enteral fluid ```
Pneumonia ``` Symptoms and findings • Cough and fever (> 38,5 o C) • Respiratory distress – Grunting, rapid respiratory rate, nasal flaring, but not always possible to diagnose on auscultation. • Consolidation on chest X-ray. ``` • Bacteria and/or virus! For Infants: RSV, Adenovirus, Influenzavirus, Parainfluenza, strep. pneumonia, Staph. aureus, Haemophilus influenza, c. trachomatis. Antibiotic treatment for pneumonia and other RTI • If antibiotics are prescribed, judged by clinical picture and after careful diagnostics; Please choose Penicillin V first! – Narrow spectrum, but covers both pneumococci and streptococci (Gram positive)!! • Second choice; a macrolide – Associated with more resistance – GIT disturbance – Cover mycoplasma and chlamydophila
31
Osteomyelitis and septic arthritis Infectious agent in the joint or bone. Early recognition important. Prompt antibiotic treatment. Bacteria enter the bone/joint, usually through the blood stream (hematogenous). Different blood supply in young children. Osteomyelitis may spread through non-ossified growth plate into the joint (arthritis). ``` Symptoms – Painful, immobile joint – Fever May also observe • Swelling • Tenderness • Red and warm ``` Most common infectious agents in childhood osteoarticular infections 0 - 1 month: Strep B, Staph aur, Gram negative bacilli 1 month - 4 years: Staph aur, Kingella kingae, Strep A > 4 years: Staph aur, Strep A ``` Anatomical location Osteomyelitis • Neonate – Often FEMUR and humerus • Child – Metaphysis of long bones (distal femur, proximal tibia etc) – Pelvic and vertebral infections ``` Septic arthritis • Knee, hip, ankle, elbow • In 25 % a concomitant osteomyelitis Diagnosis and treatment of Osteomyelitis • X-ray – Not sensitive early!! • Radionuclide bone scan • MRI !! – BEST method ``` • Blood tests (CRP, ERS) • Blood cultures • Aspiration from bone? • Antibiotics (long) – Initially IV, then PO – Staphylococcal coverage ```
Septic arthritis • Hematogenous spread of bacteria to the joint • Often hip • DD reactive arthritis • Antibiotics – Like for osteomyelitis Leg held: flexed, abducted, externally rotated. No spontaneous movements (pseudoparalysis).
32
Vaccination Immunologic memory to a pathogen. The most effective means of controlling infectious diseases. Herd immunity.
How are vaccines made? • Weakening the pathogen (live): Cell culture adaptation. – Examples: measles, mumps, rubella, chickenpox, BCG • Inactivating the pathogen: The virus is killed; cannot replicate. – Examples: polio (IPV) • Use part of the pathogen: A piece of the microbe is used to make the vaccine using recombinant techniques. – Examples: HPV and hepatitis B • Toxoid vaccines: Inactivated toxins are called toxoids. – Examples: diphtheria, tetanus and pertussis (DTP) • Polysaccharide vaccines: – Not good inducing immunological memory in children, and less effective < 2 years. – Used in adults (pneumococcal vaccine etc.) • Conjugated vaccines: polysaccharides are attached (conjugated) to a helper protein to make the vaccine. – Hib, pneumococcal and meningococcal vaccines. – Induce immunological memory in children < 2 years.
33
Immunisation programme in Norway: 6 weeks: Rotavirus, given orally 3 months: Rotavirus, diptheria, tetanus, whooping cough, poliomyelitis, Hib infection and hep B, pneumococcal 5 months: 12 months: 15 months: MMR (measles, mumps, rubella) 2nd grade, approx. 7 years: 6th grade, approx. 11 years: MMR 7th grade, approx 12 years: HPV, 2 doses 10th grade, approx 15 years: Diptheria, tetanus, whooping cough and poliomyelitis (DTP-IPV) Tuberculosis (BCG)
Aim (WHO 1988): Eradicate polio! – A reduction from an estimated 350,000 cases in 1988 to about 1,000 cases per year today. – America and Europe are declared “polio-free”. Haemophilus influenzae B (HiB) vaccination introduced in Norway in 1992 – ”Eliminated” HiB meningitis and epiglotitis ``` MMR • Measles – a major killer in developing countries – May cause severe encephalitis. – Severely sick patients – High fever and rash "Prior to vaccine “measles was as inevitable as taxes and death”. ```
34
Facts about TB (WHO) • In 2016 – ~ 1/3 of the world’s population infected. – ~ 10.4 million developed TB disease. • ~ 0.5 million develop MDR-TB. • ~ 1 million children infected. – Annually ~ 250 000 children die of TB. – Preventive treatment: ~ 13% of eligible children. • Norway around 1900 – 6-7000 people died of TB each year.
Tuberculosis Exposition - Infected (~10-30 %) - Latent TB (~90%, asymptomatic) TB disease ~ 10% (clinical symptoms) No treatment ~ 50% die within 2 years Treatment --> Cured TB symptoms in children • Small children: Fever, chronic cough, failure to thrive. • Older children: Chronic and Productive cough. What is different with child TB? • Immature immune system. – Development from latent to active TB. – Short incubation time: 4-8 weeks.. • Extra-pulmonal TB more often (25-35%). – Lymphglands, pleura, meninges, joints.. • 60% among children < 5 years. • Early diagnostics and treatment of latent TB is very effective.
35
Pulmonary TB ``` • Segmental lesions (< 10 years) – Obstructive emphysema – Atelectasis (collapse-consolidation) – Bronchopneumonia – (Hilar adenopathy) ``` • Chronic cavernous disease – > 8-10 years of age – HIV+ ``` Ekstrapulmonary TB • Meningitis and miliary TB – Mainly < 2 years of age • Lymph nodes – Most common extrapulmonary TB • Bone/spine • CNS ```
Diagnosis * Clinical history * Symptoms/clinical signs * X-ray; thorax • Mantoux: Positive 4-6 weeks after infection ! Negative: 0–5 mm Positive: ≥ 6 mm BCG reaction: 5–10 mm Quite sensitive, but not specific. Also positive after BCG-vaccination and after exposure to atypic mycobacteria. May be false negative in HIV+, malnutrition, small and very sick children. • InterferonGammaReleaseAssay = IGRA – More specific (98-99%); for M. tubeculosis • No reaction to BCG ! • No reaction to atypic mycobacteria – More sensitive in immunosuppression • Does NOT distinguish between latent and active TB • Bacteriology- SMEAR is the «GOLD standard» – Microskopi positiv – PCR (m. tuberculosis complex)
36
TB treatment Standard: 6 months antibiotic therapy Rifampicin (RIF), Isoniazid (INH), Pyrazinamide (PZA), Ethambutol (EMB) (Husk RIP-E) Daily for 2 months RIF + INH Daily or 3 times a week for the next 4 months
``` Latent TB - Asymptomatic • Pos. Mantoux and IGRA-test • Chest X-ray: Normal • Clinically healthy !! • If untreated the TB can reactivate later in life and turn into TB disease ``` TB prophylaxis - Latent TB (LTB) • Indication (FHI in Norway) – If a child/adolescent is < 18 years of age and originally from a high prevalence region, then they should receive TB prophylaxis. – TB prophylaxis = INH + RIF for 3 months • RIF 10 mg/kg/d (maks 600 mg) • INH 10 mg/kg/d (maks 300 mg)
37
BCG • Recommendation today (Norway) – Vaccinate newborn infants of parents from high prevalence regions. – Vaccinate any not infected child where there is TB in the local environment. – Since 2009 the BCG vaccine is NO longer part of universal immunisation programme (10. class). • Infants are vaccinated in the delivery ward or at the public health service.

38
``` Hepatitis A • Fæco-oral transmission • Icteric • Usually benign course • Vaccination ``` Hepatitis C • Transmission: blood • HCV-PCR positive are contagious • Vertical transmission most important among children – 79-80% develop chronic HCV infection --> fibrose --> Cirrhose --> cancer. • HCV-PCR positiv mother: 4-7% risk of infecting the child • HCV risk women – test for HCV antibodies during pregnancy. Treatment • HCV-PCR pos children should considered for treatment. • Antiviral treatment. • Goal treatment: lower viral replication to stop liver damage development.
Hepatitis B • Acute infection. – Small children - few symptoms. – Older children - flu-like symptoms, fatigue, abdominal pain and joint pain. • Leading cause of chronic hepatitis, liver cirrhosis, liver failure and hepatocellular carcinoma in the western world. Vertical transmission (perinatal) – Cause ~ 50% of chronic hepatitis worldwide. – 90% with hepatitis positive mothers are infected. – Cecarian section does NOT protect. – Breastfeeding no risk of infection Horizontal tranmission – Blood – Vaginal secret and other body fluids – Injection drug users • HBsAg (surface antigen); Virus are present, infectious • Anti-HBs (surface antibody); Vaccination response • HBeAg (antigen); Active infection and replicating virus • AntiHBc (core antibody); Increases after/during infection, NOT vaccination • HBV-DNA; Conc of virus in blood, 1 week after infection • Sero-conversion; Clearance of HBeAg and production of Anti-HBe Surface AG and core = Infection Anti-HBs = Vaccinated
39
Prevention of mother-child transmission • No prevention: 90% of children are infected • Prevention: – Immunoglobulins and Hep-B vaccine within 24 hours after birth! – Hep-B vaccine at 1 month – Vaccine at 3, 5, 12 months – AntiHBs and HbsAg 1-2 months after the last vaccine

When to expect a primary immunodeficieny condition? - Often congenital. - Resulting from genetic defects in some components of the immune system. • Frequent serious infections. • Infections with unusual pathogens. • Abscess. • Often failure-to- thrive. * 120 genetical defects associated * SCID = Severe combined immunodeficiency * IgA deficiency * IgG deficiency Secondary = acquired
Patient grops with increased risk of infections * Premature: Immature immune system. * Cytotoxic drugs: decreased number gr.c, bacteria, fungi. * Prednisolon: Reduced inflammatory response. * Transplanted: Immunosuppressive treatment. * Anti-TNF: inhibits important parts of the immune response. * HIV: The virus destroys Th cells first. * Spleen-ectomized: pneumococcal infections. * Bone marrow failure: reduced number gr.c and lymphocytes. * Neutropenia. * Primary immune deficinency.
41
IgA deficiency – Most common humoral antibody deficiency ! – 50-80% asymptomatic. – Recurrent sinopulmonary infections most frequent manifestation. – May have severe malabsorption (chronic diarrhea). – Isolated low IgA level. – Increased risk of autoimmune disorders.
X-linked agammaglobulinemia (Bruton) * Asymptomatic to 6 months. * As long acting maternal IgG (from placenta). * Repeated lung infections. * Lacking BKT gene (Bruton tyrosine kinase) that creates a signaling molecule req. for early B cell ext. * Lacking B lymphocytes, and also Ig. * Reduced lymphoid tissue. * Beh: IgG sc.
42
Neutropenia Severe: granulocytes < 0.5 ! Very serious: Granulocytes < 0.1 Consequences: Reduced infection defense, especially against bacteria and fungi. Reduced inflammatory reaction -> little CLINIC. Causes: - Acute leukemia (bone marrow infiltration) - Cytostatics Fever and neutropenia = MEDICAL EMERGENCY > 38.5 C, gr.c < 0.5 Often small clinical symptoms. CRP good parameter (the day after). High mortality in sepsis, if not early iv treatment ! Clinical presentation: - Most commonly, bacteremia without focal findings - Lung (pneumonia) - Soft tissues (cellulitis, perianal abcess, CVC) - sepsis - UTI Antibiotic treatment - Ampicillin and Gentamycin - Alternatively: cefotaksim, ceftazidim If no effect after 3 days, consider: - Vancomycin (against KNS - Koagulase-negative stafylokokker) - Metronidazol against anaerobics, esp with gut symptoms - Fluconazole/ambisome against fungi

BREAST MILK 0 – 3 months: 150 ml/kg bodyweight and day 4 – 6 months: 130 ml/kg bodyweight and day Self regulation THE INFANT DIET FROM 0 - 6 MONTHS OF AGE Exclusive breast feeding is highly recommended ESPGHAN: No complementary feeding is advised before 17 weeks of age (~ 4 months) and should not b postponed to later than 26 weeks of age (~ 6 months). The human milk substitute formulas are the only approved nutritional substitution for human breast milk when breastfeeding is not possible.
VITAMIN D Vitamin D supports the absorption of calcium. Vitamin D supplementation is highly recommended to all infants from 4 weeks of age. Supplements: 5 ml cod liver oil (tran) or 5 vitamin D- drops gives 10 μg of vitamin D.
50
THE INFANT DIET FROM 6-12 MONTHS OF AGE Gradual introduction of complementary foods. Small portions. Porridge and soft foods are necessary before introducing bread and more lumpy foods. PORRIDGE FOR INFANTS It is important to choose an IRON enriched porridge. Non enriched cereals should, if used, mainly be used as taste variation, due to the lower iron content. HOME MADE BABY PORRIDGE? It is important to know what you are advising! «Experts» advise parents to use dried apricotes to enrich the porridge with iron. One desiliter iron enriched Nestlé powder (porridge from 8 months) gives 3,0 mg jern. From 6 months of age breast milk / formula should not be the only source of energy. Iron rich foods and enriched porridge is important to prevent iron deficiency.
FOODS THAT SHOULD - NOT - BE INTRODUCED DURING THE FIRST YEAR: - Honey (infant botulism). - Spinach, beetroot, leaf celery, nettle and fennel (nitrate / affect oxygen transportation). - Smoked and salted fish and meat (salt). - Fish liver and Svolvær- and Lofot pate (dioxines). - Be aware of soil residues on herbs, cabbage and similar (bacterias). - Salt should not be added to the infants diet before 12 months of age due to the limited ability to excrete salt. - Artificial sweeteners and products containing these are not recommended for children before 3 years of age. RICE MILK AND RICE COOKIES - Not suitable for children under the age of 6 due to the high levels of inorganic ARSENIC.
51
DRINKS FROM 6 - 12 MONTHS - Breast milk and / or formula together with meals. - If the infant is thirsty between meals some water can be offered from 6 months of age. - Fruit juices and saft should not be given in bottle (dental health).
BREAST MILK VERSUS COW’S MILK PER 100 ML ``` Breast milk vs Cows milk Kcal 70 vs 63 Protein 1,3 vs 3,3 Carbohydrates (lactose) 7,2 vs 4,6 Fat 4,1 vs 3,5 ``` Breast milk = more energy, carbohydrates and fat, LESS protein.
52
COW’S MILK - From 1 year of age it is recommended that children drink cow’s milk. - Fat reduced dairy products. - Three glasses per day. Cow’s milk and other dairy products are the only sufficient calcium source in the diet. Portion sizes: - 250 ml of milk = 290 mg Ca - 2 slices of cheese (30 gram) = 215 mg Ca - 125 ml of yoghurt (1 cup) = 90 mg Ca - 100 grams of boiled broccoli = 46 mg Ca
”CALORIES” = KILOCALORIES = KCAL - Gives the energy that the little body need for maintenance, growth and activity - 1 gram of carbohydrate = 4 Kcal - 1 gram of protein = 4 Kcal - 1 gram of fat = 9 Kcal
53
Neophobia: A “picky eater” - Afraid of unfamiliar tastes - Bitter versus sweet - A normal phase of development - Peaks around 1,5 years of age - A “picky eater” may still be able to get enough variation and have sufficient growth - 10-15 taste repetitions - Regulation may be week-to-week rather than day-to-day - This is normal! - Focus on growth, not portion sizes Toddler = 12-36 months.
CHECK QUESTIONS: When should parents start introducing solid foods? - When the baby seems interested, earliest by 4 months, latest by 6 months What texture is recommended to start with? - Soft, mixed What kind of supplements will the infant need? - Vitamin D (10 μg) Why choose an iron enriched porridge above home made? - It’s easier to cover the needs Why should not a 9 month old infant drink cow’s milk? - It contains too much protein compared to needs and it does not contain iron Should a toddler drink full fat milk? - No, the recommendations says lean milk with maximum 0,7 % of fat How much milk products will a toddler need to get enough calcium from the diet? - 500 - 600 ml/day including milk and yoghurt How can we get a 1,5 year old to like vegetables? - Awareness of the neophobic phase (normal development) - Keep on trying without pressure Should we act or await if we see abnormal weight gain in a 3 year old? - It’s recommended to act early. The intervention should though be “invisible” in front of the child. What do the Norwegian recommendations say about duration of breastfeeding? - Exclusive breastfeeding is highly recommended and should be encouraged for the first 6 months, continued in addition to solid foods between 6 - 12 months and thereafter as long as the mother and baby feels happy with it. Will the breast milk fully cover all needs during the first 6 months of life? - Yes, except for vitamin D

Enzyme disorders Glucose-6-P dehydrogen. Deficiency • Susceptible to oxidants (lack of glutathione) • Symptoms depend on level of enzyme activity • Some drugs, chemicals and food worsen the deficiency - Hemolysis within 24h - Avoidance of the drugs
63
Hemolytic anemias Hemoglobinopathies Thalassemias • Mutation of globin genes - Number of affected chains determines severity (major[3α; 2β ]/minor[2α; 1β]) - Microcytic, target cells - Hb-electrophoresis - Severe forms: Regular transfusions -> hemosiderosis - If untreated: Extramedullary hemopoiesis
``` Sickle cell disease • Mutation β-globulin gene - HbS-tetramer with α-chains - Deoxygenation -> Sickle shape • Destruction in spleen - Hemolytic anemia • Thrombosis -> Ischemia - Vaso-occlusive crisis (pain!) - Splenic sequestration crisis - Acute sickle chest syndrome - Analgesia, hydration ```

Jaundice = Ikterus * 50-60 % of healthy newborn become clinically jaundiced during the first week of life. * UNconjugated bilirubin is potentially TOXIC for the immature brain. * Kernicterus can lead to serious neurologic complications. Use of resources: - Approximately 3000 infants treated - Phototherapy – admissions/longer hospital stay - Blood samples - Possible follow-up Consequences for the infant and family: - Blood samples - Separation - Worried - Delayed discharge
Kernicterus • UNconjugated bilirubin crosses the blood-/brain barriere • Neurotoxic – mainly in the basal ganglia Presentation • Jaundice within first day of life or rapidly increasing bilirubin levels: Suspect hemolysis due to immunization.
84
Hemolysis because of immunization Mother produce antibodies against the infant’s blood type Increased hemolysis → Heme ↑ ``` 1. ABO-immunization • Morther O, produces anti A el B • Common - 15-20% of pregnancies • Rarely direct Coombs pos (DAT) • Seldom prenatal symptoms ``` 2. Rh-immunization 3. Other immunization • Kell, Kidd, Duffy, Lewis, Lutheran,
Rh-immunization Anti-D-prophylaxis • to all Rh NEGATIVE women who have given birth to a Rh POSITIVE child. • Substantial reduction in immunization. Suspect when: • Rh antibody titer >256 or significant increase in titer during the pregnancy (> 2x). ``` Umbilical cord sample from all Rh neg women: • Hb • Bilirubin • Direct Coombs (DAT) - Add anti-humane globulin ```
85
Rh-immunization * More serious than ABO-immunization * Rare after anti-D-prophylaxis Serious type: 1. Erythroblastosis foetalis • Serious anemia • → heart failure in the fetus 2.

Epilepsy Epilepsy is a disease of the brain defined by any of the following conditions: 1. A least 2 unprovoked (or reflex) seizures occurring >24 h apart !! 2. One unprovoked (or reflex) seizure and a probability of further seizures similar to the general recurrence risk (at least 60%) after 2 unprovoked seizures, occurring over the next 10 years. 3. Diagnosis of an epilepsy syndrome Epilepsy is considered to be resolved for individuals who had an age-dependent epilepsy syndrome but are now past the applicable age or those who have remained seizure-free for the last 10 years, with no seizure medicines for the last 5 years.
• An epileptic seizure is caused by acute disturbances in the electric activity of the brain. • All people can experience an epileptic seizure! – Provoked by infections, head trauma, fever (child), drugs/alcohol, sleep deprivation etc. – ~ 10 % have one epileptic seizure attack during life. Highest prevalence in the first years of life – Cumulative risk of epilepsy first 20 years of life: 1% – Prevalence in childhood ~ 4-6/1000 • ↑ ↑ prevalence children with mental retardation and cerebral palsy. Pathophysiology: • Synchronized hyperactivation of brain cells. • Neuronal cells affected by neurotransmitters: – Excitatory synapses: Glutamate binds to NMDA- and AMPA-receptors. – Inhibitory synapses: GABA binds to GABA- receptors (α, β, γ subunits). Genetic epilepsies may be caused by mutations in genes that code for ion channels or their accessory subunits – Genetic panels (exome sequencing) Genetic epilepsies ≠ no obvious structural lesion/damage
99
All brain functions controlled by electric impulses – Movements, muscle activity – Thoughts, consciousness – Smell, taste, hearing – Emotions, fear, laughter • All these functions can be affected/ disturbed during an epileptic seizure.
Focal onset - Aware - Impaired awareness Generalized onset - Tonic-clonic Unknown onset Unclassified
100
Generalised tonic-clonic (”GTK”) seizures - Loss of consciousness - Initial tonic phase - Subsequently a clonic phase - May pass urine and stool - May bite the tongue
Focal motor/autonomic seizures * Motor seizures, strange feelings/laughter/smile etc. * Duration often around 10-20 s. * Retained awareness/consciousness If altered awareness/consciousness • Often repeated movements/automatisms, longer duration
101
Status epilepticus (SE) Most seizures are brief (max 3-4 min) Convulsive SE more serious than non-convulsive SE 1. Early SE: Duration 5-30 min. – A seizure lasting more than 4-5 minutes requires aggressive management! 2. Established SE: A seizure lasting longer than 30 min or a series of seizures without a return to baseline level of alertness between the seizures. 3. Refractory SE (RSE): Seizures that persist despite treatment with adequate doses of an initial 2 or 3 anticonvulsant medications.
Neonatal seizures Incidence 2-9/1000 live born infants * Secondary to transient disturbances in oxygenation, cerebral blood flow, metabolism and/or infections. * Subclinical seizures are common; only possible to detect with continuous EEG/aEEG (amplitude integrated). * Associated with high mortality and morbidity! • Increased risk of neurological sequela and post-neonatal epilepsy
102
Infantile spasms (IS) West syndrom; severe epileptic syndrome • Incidence 2-4 per 10 000 live births – 12-25 infants in Norway each year • Peak age of onset 3-7 MÅNEDER – 90% of presenting in the first year, rarely > 18 months • > 70 % symptomatic (underlying cause identified) – Cerebral malformations, chromosomal anomaly, tuberous sclerosis, congenital infections, metabolic disease etc. • < 30 % unknown cause (”cryptogenic”) – No underlying cause identified and normal development present prior to the onset of spasms. History and symptoms: • Developmental stop or even regression!! • Spasms are variable in frequency; may be brief, sudden, and subtle (head nod); easily missed. • Initial phasic component lasting a few seconds followed by a less intense, more sustained tonic contraction lasting up to 10 seconds – Often clusters of spasms – “Salaam attack” • After the spasms the child often complains/cries – Misinterpreted as abdominal pain!!
Infantile spasms Diagnostic work up and treatment • Typical EEG = Hypsarrhythmia – Chaotic, non-rhythmic, asynchronous, disorganized, high-voltage spike and slow-wave activity • MRI – Malformations/injuries? • Treatment – High-doses steroids and/or vigabatrin; side effects! – Other antiepileptic drugs or surgery Outcome • Only 5-10 % achieve normal or almost normal intelligence, the other become moderate to severe mentally retarded. • 60-90 % have persistent seizures and often develop other severe seizures types. • Associated with a favourable prognosis: 1. Normal development at onset 2. Unknown cause 3. Rapid response to treatment
103
Febrile seizures • Seizures in febrile children between the ages of 6 months and 5 years who do not have an intracranial infection, metabolic disturbance, or history of afebrile seizures. – Peak incidence between 12-24 months – Rarely onset after 4 years • Fever: – Unknown whether a rapid increase in temperature or the maximum temperature is most important. ``` Classification: • Simple febrile seizures – Generalised seizure – Duration < 15 min – Occur once in a 24-h period ``` ``` • Complex febrile seizures Defined by one of the following: 1. Focal seizures 2. Prolonged seizure attack (> 15 min) 3. Multiple; occur more than once in a 24-h period ``` ``` Incidence – 2-5 % of all children – ~ 20 % of first attack are complex febrile seizures • Risk factors for development of febrile seizures – Family history of epilepsy – Developmental delay – Preterm birth > 50 % do not have any risk factors ``` ``` Risk of recurrence • ~ 30 % have only one more episode • ~ 15 % have two more episodes • ~ 7 % have three or more episodes – Risk of recurrence ↓ if > 6 months since last episode • Risk of recurrence is higher: – Age between 12-24 months – Positive family history – Age < 12 months at first episode – If multiple seizures at first episode ``` Very low risk of developing epilepsy later in life • If only 1-3 simple febrile seizure attacks there is no increased risk of developing epilepsy. • Slightly increased risk if: – Complex febrile seizures – Positive family history of epilepsy – Delayed development/neurological abnormalities EEG Often abnormal EEG-findings after an episode. • EEG has no predictive value with regard to risk of developing epilepsy and should NOT be taken: – After one episode of complex (or simple) seizures – Even after repeated episodes of simple febrile seizures in otherwise healthy children • Who should have an EEG? – Clinical signs of neurological disease – After repeated complex seizures
Febrile seizures Can it be meningitis? Yes, but extremely rare (0-7 %) • Meningitis is very unlikely if no petechial, no neck stiffness and a simple seizure attack. • If < 12 months; often admitted, always consider LP. • Common (although often not necessary) to admit a child after first febrile seizure attack. Management • Antipyretics may improve the comfort of the child, but they will not prevent febrile seizures. • Always prescribe DIAZEPAM if needed later – Administer if seizure duration > 4-5 min • Information to the parents + empathy! – Very important – What to do during a seizure? – No deaths reported during/after a simple seizure
104
Benign childhood epilepsy with centrotemporal spikes ~ 20 % of childhood epilepsies Seizure onset: 3-13 ÅR, boys > girls Typical seizures: – 75% of seizure attacks during sleep. – Lateralised facial contraction and a grunting sound, without loss of consciousness. – Sometimes the homolateral upper limb is involved. – Secondary generalisation 1/3 - 2/3. • EEG: Characteristic centrotemporal spikes • Normal developed child! • Treatment often not necessary and does not change the outcome – 20 % only one seizure attack – 60 % low number of seizures – 20 % frequent seizures • Prognosis is excellent with remission within adolescence.
Absence epilepsy Childhood and juvenile type • Childhood type; typical onset 5-7 years – Very frequent, typical absence seizures lasting 2-20 sec – EEG: rhythmic 3 Hz generalised spike and wave complexes. – Childhood absences disappear before adulthood in up to 90% • Juvenile type; typical onset 10-12 years (girls > boys) – Frequent absences (daydreaming??) – May cluster upon awakening – Generalize tonic-clonic seizures may develop (++ by sleep deprivation) and long-term prognosis is unclear. – Associated with cognitive dysfunction and learning difficulties.
105
A non-provoked seizure attack in a child always needs further investigations! ``` History and findings • Description of seizures – Initial ictal manifestations – Duration – Different seizure types – Postictal occurrence – Precipitating factors? ``` • History – Normal/delayed development? – Behavioural problems? – Learning difficulties? Clinical examination including neurological, skin, ocular assessment, and measurement of head circumference
EEG * EEG, usually some weeks after the acute seizure (↑ prognostic value). * A routine interictal EEG has a sensitivity of 50-60 %. * Repeated EEG-examinations increase the sensitivity to 80-90 %. * Sleep deprived EEG. * Flicker stimulation. * 24 h EEG / videometry. Neuroimaging • MRI – Procedure of choice !! – Special epilepsy protocols • CT: Rarely used, not detailed enough for diagnosis. • Functional neuroimaging – In candidates for epilepsy surgery
106
``` Prognostic groups – Self-limited – Pharmaco-sensitive – Pharmaco-dependent – Pharmaco-resistant ``` * About 2/3 of children with seizures in childhood will be in remission in adulthood. * Different epileptic syndromes have very different prognosis. * The underlying brain lesion usually determines the prognosis.
Factors associated with a favourable prognosis ``` – Normal intelligence – No neurological abnormalities – Unknown cause (”idiopathic”) – Age at onset more than 2 years – Infrequent seizures – Limited numbers of “GTK” seizures – Only one seizure type – Absence of tonic-atonic seizures (drop-attacks) – Rapid response to anti-epileptic drugs (AED) ```
107
Differential diagnosis * Psychogenic non-epileptic seizures (PNES) * Breath-holding spells * Transient ischaemic attack (rare in children) * Migraine * Hypoglycaemia (always check glucose/DEFG!!) * Movement disorders/tics * Gastro-oesophageal reflux (dystonic posturing) * Night terrors * Cardiogenic syncope (long QT-syndrome, AV-block?) * Self gratification behaviour (girls 2-4 years)
Breath-holding spells In ~ 4-5% of all children (F = M), most common between 6-18 months. • Cyanotic breath-holding spells – Usually precipitated by anger or frustration (or pain). – Child cries and has forced expiration sometimes leading to cyanosis, loss of muscle tone, and loss of consciousness. • Pallid breath-holding spells – Common stimulus a painful event. – Turns pale, loses consciousness with little if any crying. • Clinical diagnosis – Good history including the sequence of events, lack of incontinence and no post ictal phase. – Some have iron deficiency.
108
First aid Epileptic seizures outside hospital • Stay calm! – Not painful and usually stops within 2-3 minutes. – Do not try to stop the seizure or to ”resuscitate” * Protect the head, place patient in recovery position * Do not put anything in the mouth • Health personnel are required only in long standing seizures ``` • Seizures > 4-5 min, give: Diazepam rectal – < 10 kg: 5 mg – > 10 kg: 10 mg or Midazolam buccal – 0,3 mg/kg ``` Repeat if necessary If a generalised seizure lasts longer than 5-10 minutes call 113; increased risk of SE.
Prevention and treatment: 1. Avoid precipitating factors – Sleep deprivation, psychological stress etc. 2. Anti-epileptic-drugs (AED) – Choice depend on seizure type – Monitoring drug concentration – Slow release tablets; stable drug concentration 3. Vagus nerve stimulation (VNS) - Used as adjunctive treatment in pharmaco-resistant epilepsy. - Vagus nerve stimulation may reduce seizure frequency. - Mechanism of action not fully understood. 4. Surgical treatment 5. Ketogenic diet • Nutrition predominantly rich in fat and maintains ketosis in the long term. • High concentrations of ketone bodies have been correlated with better seizure control. – Mechanism of action not entirely known, but ketone bodies increase degradation of glutamate and increase the conversion of glutamine to inhibitory GABA. • 20–40%: > 90% reduction in seizure frequency. – Another 20–60%: > 50% reduction in seizure frequency.
109
Side effects of AED Usually not severe, but may cause problems 1. CNS Cognition, memory, concentration, neuropsychiatric symptoms. 2. SKIN Rash, drug allergy (carbamazepine, lamotrigine). 3. LIVER 4. BLOOD/HEMATOLOGY Parents need to be informed!!
AED in different seizure types • First choice Focal seizures: – Carbamazepine (Trimonil, Tegretol) – Oxcarbazepine (Trileptal) • First choice Generalised seizures: – Valproate (Orfiril) – Lamotrigine (Lamictal) • First choice SE – Benzodiazepines (Diazepam/Midazolam) – Phosphenytoin (Pro-Epanutin)
110
Epilepsy and sport ``` • Encourage physical activity – may reduce seizure frequency. – prevents isolation. – improves fitness, balance and body control. – needs to be adjusted to each patient. ``` • Always monitor swimming!!
Epilepsy and school • Many children with epilepsy have normal IQ • May be problems with learning, cognition and memory – Subclinical seizures? – Side effects of drugs? – Absence from school? • The teacher needs to have knowledge about epilepsy – Refer to pedagogic centre if needed. – Know how to treat a seizure attack. Comorbidities • Learning problems/struggling at school – In up to 70% of children with epilepsy • ADHD • Behavioral problems • Psychiatric problems Of great importance to detect and ameliorate/ treat/help children with these problems.
111
Headache in children ``` Alarm bells • Abnormal neurology • Change in behaviour • Visual disturbances • Headache at night/early morning • Headache + seizures • Nausea and vomiting in the morning ``` Migraine in children Epidemiology • Incidence (Sweden) ~ 4 % between 7-15 years of age • Before puberty girls and boys are equally affected, later more common in girls. • Resolves spontaneously in some children after 10 years of age. • Often positive family history
Symptoms: • Headache usually pounding or throbbing, lasts between 1-2 hours, and may involve one or both sides of the head or the entire head. • Headache often accompanied by severe nausea and vomiting. • Sensitivity to light and noise; the child often wants to lay down in a dark, cool room. • Often pain relief after sleep. • If possible; avoid triggers – Stress, sleep deprivation, hunger etc. • Abortive treatment during migraine attack – Young children: Ibuprofen, paracetamol and in some cases anti-nausea medications. – Older children: same as above + sometimes a triptan given by nasal spray. • Preventive treatments: – Consider if > 3-4 attacks each month – Not used frequently
112
Paediatric Plastic Surgery Important Points • Health workers may to a great extent influence the expectations of parents to congenital defects. • The childs response to surgery is influenced by the personality of the child and the parents ability to cooperate. • Children should be allowed to participate in decision making according to their psychological age.
Orofacial cleft • Anatomy – Lack of tissue and disfigurement • Embryology – 5-7 w: Development of jaw and lip – 7-11w: Hard and soft Palate • Incidence – 2 : 1000 – Boys: Lip and Jaw – Girls: Palate, part of syndromes
113

125
We know that it happens, but why? (What are the mechanisms? 1/4) 1. The immune response change with stress – The stress hormone corticosteroid can suppress the effectiveness of the immune system (e.g. lowering the number of lymphocytes). Can lead to delayed wound healing, impaired responses to vaccination and development and progression of cancer. 2. ACEs are related to shortening of telomere lengths – Telomere shortening are associated with premature aging – Telomere shortening are associated with cardio vascular disease. – Women with high stress levels were found to have telomere shortening equivalent to a decade of aging in comparison to women with lower stress levels. The presence of multiple childhood adversities was related to both heightened IL-6 and shorter telomeres. The telomere difference could translate into a 7- to 15-year difference in life span. 3. ACEs are related to inflammation in adults. In this cohort study of 1391 young people followed up to 18 years of age in the United Kingdom, exposure to adverse experiences, stress, and violence during childhood or adolescence was associated with elevated levels of the soluble urokinase plasminogen activator receptor (suPAR) at 18 years of age, even in children who did not have elevated C-reactive protein or interleukin 6 levels. 4. Chronic stress changes the brain It has a shrinking effect on the hippocampus and prefrontal cortex. - The area responsible for memory, learning and self-regulation. It increase the size of the amygdala. - Predispositions the brain to a constant state of fight-or-flight. - Increasing anxiety, vigilance and aggressiveness. In the hippocampus and medial prefrontal cortex, chronic stress causes dendrites of neurons to shrink and become shorter and less branched, with an accompanying reduction in synaptic input. This reduces the person's capabilities for nuanced cognitive function, memory and self-regulation. [...] In contrast to hippocampus and the medial prefrontal cortex, the basolateral amygdala and orbitofrontal cortex respond to the same chronic stress by expanding dendrites and increasing synaptic input, which lead to increased anxiety, vigilance and aggressiveness. Early life events also affect how these brain regions develop.”
Allostatic load = the long-term effect of the physiologic response to stress. – “Allostasis — the ability to achieve stability through change — is critical to survival. Through allostasis, the autonomic nervous system, the hypothalamic–pituitary–adrenal (HPA) axis, and the cardiovascular, metabolic, and immune systems protect the body by responding to internal and external stress. The price of this accommodation to stress can be allostatic load, which is the wear and tear that results from chronic overactivity or underactivity of allostatic systems.” Examples of allostatic load may be found in the: 1. primary mediators (hypercortisolemia, increased inflammatory cytokines), 2. secondary outcomes (elevated blood pressure, overweight, insulin resistance), or 3. tertiary outcomes (hypertension, diabetes, obesity, coronary heart disease, neurodegenerative disorders).
126
Is it contaigous? (The inheritance of ACEs) A parent’s ACE score is linked to the child's outcome. – “For each additional maternal ACE, there was an 18% increase in the risk for a suspected developmental delay [...] A similar trend was observed for each additional paternal ACE” 1. Direct epigenetics – Epigenetic changes that occur in the lifespan of an individual, due to direct experiences with his environment. • Regulation of gene expression by transcription factors, starting a cascade of adaptive events which ultimately leads to long-lasting effects. 2. Indirect epigenetic changes - within • changes that occur inside of the womb, due to events during gestation (=fetal programming). e.g. diet, smoking, alcohol. 3. Indirect epigenetic changes - across • Epigenetic changes inherited from one generation to the next
Implications for society * Our disposition for health and unhealth is not «fair». * Health is not just a product of how we ‘choose’ to live our lives. * Disease is not evenly distributed. • We could remedy this by giving most to those that need it most, but: – Medical and social resources are not evenly distributed. – The inverse care law: ”The availability of good medical care tends to vary inversely with the need for it in the population served. This inverse care law operates more completely where medical care is most exposed to market forces, and less so where such exposure is reduced.”
127
Is all lost? What can we do? PREVENTION ``` STRUCTURAL • Reducing child poverty • Legislation against and information about corporal punishment • Screening tools for ACEs(?) ``` INDIVIDUAL • Support positive interactions between children-parents (E.g. parenting training programs) • Early childhood home-visits (e.g. health nurses) BUFFERING (REDUCING IMPACT) STRUCTURAL • Developing trauma-sensitive workplaces/systems • Encance primary care • Encance Child Protective Service INDIVIDUAL • Notify and cooperate with Child Protective Service ! • Support parents ‘emotional availability’ towards child • Reinstate positive caregiving environment
Take home message (for your life as a doctor) • ACEs are real, and will affect many of your patients. • Listen to your patient’s story – and be prepared to receive it when the patient is ready to tell you. • Don’t be afraid to ask. • Life stressors will affect people (and families) differently – never assume you know the baggage the person in front of you carries with them. • Train yourself in how to evaluate interaction between child and caretaker. • Contact child protective service when suspecting abuse or neglect. – If in doubt: – contact the child protective service and discuss the case anonymously. – Rather one time too many!
128
Cerebral palsy (CP) ”An umbrella term” defined as ... • .. a heterogeneous group of clinical syndromes with motor and postural dysfunction due to a defect or LESION of the immature brain. – Arising in early stages of development (< 2 y of age). • Non-progressive damage/lesion, but the clinical picture changes over time. • Must exclude other conditions that may mimic CP – Progressive disease! – Spinal injuries/diseases – Hypotonia alone Prevalence: • Most common cause of neurological motor dysfunction in children. • 2-2.5/1000 in the industrialized world. – Around 120 new CP cases in Norway/year • 1/3 born preterm
CP Aetiology – 1 Prematurity • Periventricular leukomalacia (PVL) • Intracranial haemorrhage (ICH), usually grade 3-4 – What caused the premature birth? • 5-10% of infants with BW < 1.5 kg develop CP – Higher risk if complications Severe ICH Grade 3 and 4 • Grade 3 – At least 10-15% develop severe problems – A higher number if persistent dilatation of the ventricles • Grade 4 – 50-60 % CP – Also cognitive problems

Aetiology – 2 ”Birth injury” or perinatal asphyxia Accounts for only 10-20% CP • Asphyxia may cause injury if: – 5 min Apgar < 4 – Umbilical cord: pH < 7.0 and/or BE < -12-16 – Moderate-severe hypoxic ischaemic encephalopathy (HIE) But: 10 min Apgar 1-3 → only 10-15% CP Therapeutic hypothermia ..to prevent brain damage after perinatal asphyxia Aetiology – 3 ``` Other perinatal factors • Neonatal stroke – Acute vascular catastrophe • Hyper-bilirubinemia – Rhesus or ABO-immunisation – severe cases → Kernicterus – choreoatethosis/hearing loss – Rare today!! • Syndromes/cerebral malformations ```
Aetiology – 4 Multiple perinatal risk factors? Exponential increase due to multiple factors? – Especially preterm infants – Term babies; only 1/3 have two or more factors Individual/genetic susceptibility? Unknown cause: 30-50% term babies with CP • Occult infection/inflammation? • Vanishing twin syndrome? ``` Aetiology – 5 Postnatal (< 2 years); 5% of all CP cases • Sequela after – Severe epilepsy – Meningitis/encephalitis – Injuries/drowning – Metabolic crisis ```
130
Diagnosis CP IS A CLINICAL DIAGNOSIS - Often doctor and physiotherapist. • Cerebral MRI – To establish aetiology • Sometimes other investigations to rule out other causes – Genetic analyses? – Screening for inborn errors of metabolism? – Other?
CP - early clinical signs ``` • Often detected during follow up of ”high risk babies” – Feeding difficulties – Poor or ”too good” head control – Abnormal pattern of movement – Fisting of one hand – Early favouring of one hand – “Limp” when starts to walk ``` ``` Change in muscle tone? • Scissoring of the legs after 2 months of age – Increased hip adduction • Extension of the legs • ”Good” head control in prone position – Extension of spine and neck ``` Difficult to diagnose < 6 months of age – Risk factors! Usually obvious by 12-18 months of age – Poor quality/delayed motor milestones – Asymmetrical pattern of movement – Muscular hypertonia (NB hypotonia early) – Persisting primitive reflexes and increased deep tendon reflexes
131
Babinski sign Primitive reflex; normal sign i newborn infants Later in life it indicates an upper motor neuron lesion
CP- classification 1. Motor type? – Spastic: 70-80% Most common! Muscular appear stiff and tight. Arises from motor cortex damage. – Dyskinetic (6%): Dystonic or Choreoathetotic Involunatay movements. Arises from basal ganglia damage. – Ataxic – Mixed 2. Parts of the body involved? – Unilateral or bilateral – How many limbs affected 3. Gross motor skills? – Difficult to classify < 2-3 years of age
132
Spasticity - patophysiology Lesion in upper motor neuron (brain/pyramidal tract) 1. Impaired excitatory pathways Fewer motor units leading to reduced muscular strength and control. 2. Impaired inhibitory pathways Spasticity due to increased muscle tone.
Spasticity «Velocity dependent resistance to stretch” - Lack of inhibition results in excessive contraction of the muscles. - Occurs mainly in disorders of the CNS affecting the upper motor neuron.
133
Unilateral spastic CP (Spastic hemiplegia) • 4 months - clenched hand • 6 months tone - and reflexes asymmetrical (upper extremities) * Late crawling, asymmetrical * 12-15 months apparent in lower extremities * Visual field defects, poor stereognostic ability * Often “normal” cognitive function
Bilateral spastic CP (Spastic diplegia) • Spasticity both legs – Hypotonia 1st year – Upper extremities also involved, to a lesser degree • Often ex-premature babies! • Cognitive function often good • Perception, visual motor coordination often difficult • Severely handicapped children • Microcephaly, mental retardation, epilepsy, respiratory problems, feeding difficulties, visual problems • Causes – Factors early in pregnancy – Hypoxic ischaemic encephalopathy II-III
134
Comorbidity ``` • Seizures – 1⁄2 seizures neonatal period – 1⁄4 epilepsy in need of treatment • Visual and/or hearing problems • Perceptual difficulties – Distance, proportions etc. leading to impairment of motor skills ``` • Intellectual disability – Mental retardation 30-50% • NB Appearance may be ”less intelligent” – Motor problems/involuntary movements – Drooling • Mild CP may also include specific learning problems/ speech problems. ``` • Feeding difficulties – PEG • Gastrooesophagal reflux • Constipation • Respiratory difficulties – Retention of secretions ```
Complications – scoliosis – hip luxation Treatment • Permanent brain damage - no curative treatment • Goal: – Best possible cognitive/motor function – Improve level of functioning, daily living – Reduce spasticity Botox - Purified botulinum toxin protein 1. Injection directly in to the affected muscles. 2. Two-thirds of the patients receive doses in their legs 3. Inhibits the release of acetylcholine from nerve cells, blocking the signals that promote involuntary muscle contractions 4. Symptomatic treatment Intrathecal Baclofen • Indications: bilateral spastic, quadriplegia • Indications: severe spasticity, pain, difficult handling • NB complications! Orthopaedic surgery • Indications fixed contractions or joints in wrong position • Mainly older children • Elongation/transposition of muscle/tendon
135
Take back to school messages • Variable clinical pictures - all interfering with posture and movement – Children ranging from almost normal to severely multi-impaired • Spastic CP most common form! • Multifactorial etiology common – Prenatal factors important – Increased risk among very preterm infants • Comorbidity (intellectual disability, epilepsy, impaired vision etc) common. • Permanent brain damage • Goal: Treat spasticity, avoiding complications, improve level of functioning
.
136
Children and medications • Neonate: – Up to one month post utero • Infant: – Between the ages of one month and two years • Child: – Between two years and 12 years of age
Prematures and neonates: • More body water and less fat than older children • Liver and kidneys: Immature • Deviation from normal organ function – The younger and the more premature, the bigger deviation
137
Children and pharmacokinetics Absorption • Neonate’s and absorption through skin – Immaturity is the most important factor that determines percutaneous absorption. – Very immature infants in the early neonatal period have a poorly developed epidermis, which is readily permeable to drugs: • Extreme caution with antiseptics • Caution with steroids, avoid long term use ``` • Oral administration: – Up to 6 months: Emptying of ventricle is delayed • Rectal administration can be useful – Vomiting – First pass metabolism ``` Distribution • Prematures and neonates: high percentage of body water – → Different volume of distribution – Increased volume of distribution for water soluble drugs – Reduced volume of distribution for lipid soluble drugs Low concentration of plasma proteins – Reduced protein binding of drugs → Increased amount of unbound drug → stronger effect – Particularly relevant for antiepileptics
Elimination • Renal function: Increases gradually the first 6 months • Liver function: Increases rapidly the first 4 weeks • Reduced elimination: → Increased half-life → Longer time until Steady State is obtained → Longer time until the drug is eliminated from the body Liver: • Enzymatic activity undeveloped at birth • Microsomal enzymes involved in oxidation and glucuronide conjugation may be missing or be present in very low amounts → Bilirubin and drugs like chlorpromazine are metabolized very slowly. • Rapid development towards adult levels (1-8 weeks after birth). Kidneys: Variation in clearance and maintenance dosage with age. Maintenance dose per kg is: • Higher for children • Lower for newborn and elderly in comparison to adults
138
Dosage • Earlier: Doses where calculated from adult dose and adjusted for the infant’s weight. → Drug concentration too high Higher max- Concentration because of reduced rate of elimination. Dosage • Especially important for multiple-dose regimens • Accumulation to toxic levels Dose per kg increases gradually with age • Example of dosage regimen (Apocillin) – Adults: 1,3-4 g per 24 hours – Children: 33-66 mg per kg per 24 hours • Fully developed neonates: 1st and 2nd day after birth 20 mg per kg per 24 hours • 3rd to 6th day after birth: 27 mg per kg per 24 hours • 2nd week: 33 mg per kg per 24 hours • 3rd week to 3 months: 50 mg per kg per 24 hours
• Paradoxical effect of certain CNS drugs Diazepam, phenobarbital - Insomnia, restlessness, irritability Increased effect: – Opioids can give respiratory depression even in moderate doses. In general, little is known about differences in pharmacodynamics between children and adults. ``` Children and drug posioning • Most common at the age 1-3 • Most serious poisonings: – Iron tablets – Salicylate – Sedatives ``` Commonly used medications for children • Penicillin and erythromycin – (Avoid tetracycline!) • Paracetamol / acetaminophen – (Caution with acetylsalicylate for children under the age of 12!) • Desmopressin (nasal spray for treatment of nocturnal enuresis).
139
Some facts • 23 % of children in Norway are living with parental mental illness and 6,5 % living with parental alcohol abuse – in a way that implies daily function • 3500 children of parents who are diagnosed with cancer every year, 13000 children-families are living with cancer • Heterogeneous group–individual need • Illness in a family always affect the children ! * Implications for the children: practical, social, emotional, mental, physical, economical * Negative attitudes; shame, blame and social stigma * Risk group for developing mental and social problems themselves * Early interventions are helpful – information, help, support and someone to talk with * The majority manage their lives well in the future * However, too many children are left to manage family situation by their own
Children do Not tolerate pain better than adults! Children’s tolerance to pain increase with age. Challenging to identify the presence and severity of pain in children. Pain during procedures and surgery, postoperative pain, and disease-related pain are inadequately controlled. ``` Physiological Indications of Acute Pain • Dilated pupils • Increased perspiration • Increased rate/ force of heart rate • Increased rate/depth of respirations • Increased blood pressure • Decreased urine output • Decreased peristalsis of GI tract ```
140
Obs Codein; Risk over severe adverse effect in children due to great variation in enzyme cytochrome P450 isoezyme 2D6 activity
Procedural anxiety • Midazolam po, nasal or rectal (0,3-0,5 mg/kg, max 15 (-20 mg). – 10-30 min before procedure – Antidot: Flumazenile 3-5 microgr/kg iv • Dexmedetomidin (1-2 μg/kg nasal) • Nitrous oxide (“laughing or happy gas”) 50/50 N2O and O2
141
Key message * UTI is a common bacterial infection causing illness in children * It may be difficult to recognise UTI in children because the presenting symptoms and/or signs are non-specific, particularly in younger children * Urine collection and interpretation of urine tests in children is not easy and therefore it may not always be possible to unequivocally confirm the diagnosis The most common presentation in infants is an undiagnosed fever.
UTI – common in children • Cumulative incidence of UTI in children up to 16 years – Boys 3-4 % – Girls 11 % • Boys: – Often first UTI during first 6-12 months of life. Underlying abnormality more common than in girls. • Girls: – Stable incidence of UTI during the first 6 years of life, but gradually more non- febrile UTIs and less febrile UTIs. – Some older girls (> 2 years) have recurrent UTIs.
142
Diagnosis of UTI requires the following 3 criteria: – Symptoms – Pyuria = leukocyturia – Significant bacteriuria (Urine sample collection a challenge!)
Urine collection bags (clean the skin first) – Reliable if negative! – Best: 2 samples before start of antibiotics – NB. At least 10 % of healthy children will have growth of bacteria in collection bags!!
143
Urine dipstick Leukocytes - Esterase activity in neutrophils - Semiquantitative leuko/mikroliter urine - Read after 60 s Def. pyuria > 10 leukocytes/mikroliter urine in boys > 50 leukocytes/mikroliter urine in girls Low grade pyuria (1-2+) is unspecific High grade pyuria (≥ 3+) indicates UTI unless contamination.
Nitrite is normally not present in urine, but may be produced by Gram neg. bacteria – Nitrate → nitrite * Gram pos. bacteria do NOT produce nitrite * Nitrite-test: 40-50 % sensitivity for UTI in children less than 2 years of age. A combination of leukocyte esterase and nitrite test has a fairly good sensitivity and specificity for UTI • NB: – Isolated haematuria and/or proteinuria are not signs of UTI.
144
Urine microscopy Different techniques/traditions in different countries Advantages of microscopy vs. dipstick • Can see casts (signs of upper UTI) • Can see bacteria • Can see leukocytes and morphology Disadvantages of microscopy vs. dipstick • Time consuming • Requires experience ``` Comparison microscopy vs. dipstick • Dip stick: – 70% sensitivity – 98% specificity • Microscopy: – 80% sensitivity – 64% specificity (many false pos) ``` Choice Pragmatically: Primarily dipstick ! – Neg. dipstick (leukocytes/nitrite): No UTI – Pos. dipstick for UTI (≥ 3+ leukocytes and pos. nitrite) and symptoms: Most likely UTI – Unclear findings on dipstick; Do also microscopy
Urine culture • Urine should be sent cold to the laboratory or kept in the refrigerator before transport. – Culture within 4 hours of collection. • Growth of more than one bacterial species indicates contamination of the urine sample. • Bacteriology: – E. coli (80-90 %) – Non-E. coli bacteria: • S. saprophyticus • Proteus (UTI predisposes for nephrolithiasis) • Klebsiella (bladder dysfunction?) • Enterobacter • Enterococci • Pseudomonas (bladder dysfunction? malformation?)
145
• Upper UTI = Febrile UTI = Pyelonephritis – May cause renal scarring, especially in young children (< 2 years) - High CRP (> 50 mg/l) ``` Treatment: PO for 7-10 days – Mecillinam 10 mg/kg x 3 – Co-Amoxiclav 20 mg/kg x 3 – Oral Cephalosporin • Consider IV treatment for all < 3 months of age and if poor general condition (infants/small child) ``` • Lower UTI = Non-febrile UTI = Cystitis – No renal scarring and does not affect renal function, but may be very “troublesome”. - Low CRP (< 20 mg/l). ``` Treatment PO for 3 (-5) days – Trimethoprim – Nitrofurantoin – Mecillinam • NB. Trimethoprim and Nitrofurantoin should not be used for a febrile UTI due to poor tissue penetration!! ``` Use of procalcitonin instead of CRP in some countries
Follow up? • All children < 3 years of age – Primarily ultrasound, timing based on presentation – Further follow up restricted to ”high risk group” • Children > 3 år with recurrent UTI’s – Voiding pattern? (history) – Urodynamic (flowmetry/bladder scanning)
146
``` VCUG = Voiding urethracystography • Routinely only in children < 6 months • Children > 6 months of age: – Risk group? – Unpleasant examination ``` Antibiotic prophylaxis? • Indicated for dilated VUR age 0-1 (2) years • Choose trimethoprim or nitrofurantoin
Renal diseases Nephritic syndrome – Haematuria and proteinuria – Often hypertension – Reduced GFR (↑ creatinine) NephrOtic syndrome – Proteinuria – Oedema (often periorbital) – ↓ albumin (< 25 g/l) ``` Nephrotic proteinuria: Urine dipstick ≥3+ protein creatinine ratio > 300 mg/mmol Proteinuria > 3 g/d or protein ```
147
Glomerulonephritis (GN) Simplified classification • ”The good ones” – E.g. mild post streptoccal GN or Henoch Schoenlein GN • ”The bad ones” – E.g. SLE nephritis • ”The horrible ones” – Rapid progressive GN
Nephrotic syndrome (NS) Child • 80 % Minimal change glomerulonephritis (MCGN) – Usually small boys (less than 8-10 years of age) – ”Pure” NS, often no haematuria and normal GFR. – Responds to steroid (90 %) – Often relapses, but ”everyone” eventually become healthy Electronemicroscopy – Fusion of foot processes – Often selecetive glomerular proteinuria • Low molecular weight, mainly albumin • 20 % Light microscopic changes (biopsy) – NS + often also nephritis-like picture – Often resistant to steroids – More prevalent in older girls
148
Microscopic haematuria Follow up • Accidental finding in asymptomatic child with no fever or signs of UTI – Repeat controls twice with 3-4 weeks interval ``` Persistent microscopic haematuria: – Family history – Proteinuria? – Red blood cell morphology – Other urine analyses – Ultrasound (tumour? Very rare) – Blood samples (renal function, IgA, C3, AST) – Blood pressure ```
Isolated microscopic haematuria • May be a glomerular disease: – IgA nephritis, thin GBM nephropathy, sequela after a mild GN, Alport syndrome – Very rare urological disease • Specific diagnosis has no therapeutic consequence, thus renal biopsy not indicated. • Follow up: – Urine dipstick and BP annually. – Renal biopsy if concomitant/development of proteinuria
149
Congenital malformations Background: • ~ 1,5 % of all newborn infants are diagnosed with a malformation shortly after birth (increasingly prenatally diagnosed) – Single or multiple malformation – ”Major” or ”minor” malformation • Prevalence ~ 4-5 % when including less serious/minor malformations detected later
Congenital heart defects (CHD) * In ~ 1 % of all newborn infants; the most common type of major birth defect! * Most (~ 70 %) serious CHDs are detected within the first month of life. * A heart murmur, the hallmark of a CHD, is not always audible on the first 1-2 days of life, and may not be present at all ! * Most infants with CHD are asymptomatic at birth, but those who need treatment will develop symptoms.
150
Embryology of the heart: * The early tubular heart arises from mesoderm and cranial neural crest (outflow tract). * Cardiac tube (late in the 3rd week) is bilaterally symmetrical. * It then starts ”looping” into an S-shaped heart. * Atria and ventricles are first separated. * Disturbances in development of heart valves are critical. * In the 5th gestational week the atria and ventricle undergoes partitioning. CHD can involve walls of the heart (septum), heart valves and arteries/veins near the heart. CHDs can disrupt the normal blood flow through the heart. The blood flow can: – Slow down – Go in the wrong direction or to the wrong place – Be blocked completely Changes in flow lead to structural consequences !
Epidemiology and risk factors: ``` Chromosomal anomalies (5-20%) - Syndromes (Down, Di George, Noonan, Williams, etc.) ``` ”External” influence (2-4 %) - Virus, drugs, alcohol (FAS) No obvious cause (70-90%) - “Gene-environment interaction” - New genetic tools... Pathophysiology: • ↑ pulmonary blood flow – e.g VSD • ↓ pulmonary blood flow – e.g pulmonary stenosis, Fallot • ↓ systemic blood flow – e.g. critical aortic stenosis, HLHS • Parallel coupling of pulmonary and systemic circulation – Transposition of great arteries
151
HLHS = Hypoplastic left heart syndrome 1. Hypoplastic ascending aorta and aortic arch. 2. Hypoplastic left ventricle. 3. Large patent ductus arteriosus supplying the only source of blood flow to the body. 4. Atrial septal defect allowing blood returning from lungs to reach the single ventricle.
CHD – ”Classification” • Mild, no symptoms – e.g. Small VSD • Surgical ”repair” – ”Functional” biventricular heart • Palliative surgery – Univentricular heart etc. • Lethal
152
Most common CHD * Ventricular septal defect (VSD) ~50 % * Atrial septal defect (ASD) ~10 % ``` Alle disse har hver 3-5 % • Pulmonary stenosis • Patent ductus arteriosus (PDA) • Transposition of the great arteries (TGA) • Coarctatio aortae • Aortic stenosis • Fallot`s tetralogy • Atrioventricular septal defect (AVSD) ```
Screening for CHD • Prenatal ultrasound: – Variable detection rate (30-70%) • Pulse oximetry screening: – ~10-20 % of all CHD are duct-dependent critical/life-threatening conditions – Most of these have low SpO2 – Introduced in Troms in 2009 • Newborn examination 2-3. day of life – Clinical examination – Murmur?
153
Gastrointestinal malformations 1. Visible malformations - Cleft lip and palate - Abdominal wall defects 2. Invisible malformations - Intestinal obstructions • Prenatal ultrasound is sensitive in the diagnosis of many of these condition ``` • Inability to swallow → Polyhydramnios (= large amount of amniotic fluid) – GIT- obstruction – Cerebral ”problem” – Twin-twin transfusion - recipient ```
Cleft lip and palate ~ 1.5-2 per 1000 live born • 55-70% non-syndromic, the rest associated with anomalies/syndromes Multi-disciplinary management 1. Feeding problems! 2. Hearing and speech problems 3. Operation of the lip and the maxilla at 3 months of age 4. Reconstruction of the palate - usually at 1 year of age Special feeding bottle
154
Abdominal wall defects Omphalocele versus Gastroschisis Omphalocele Exomphalos Abdominal wall defect; - A specter ranging from small defects (hernia into the cord) to large defects. - Bowel, and often liver, are enclosed within a sac. - Frequently associated with other malformations or chromosomal anomalies. Gastroschisis • Abdominal wall defect → stomach, small bowel, COLON (rarely liver) prolapses through defect. • There is no covering membrane. • Associated with intestinal atresia, but otherwise these patients are usually healthy.
What is normal in the newborn baby? Normal vomiting - Vomits amniotic fluid after delivery. - Vomits right after feeding (milk): * When burping * After large volume feeds (hungry!!) * Due to mild reflux (physiologic) Normal stool - Meconium: The earliest stool of an infant. Black, viscous/ sticky like tar, and has no odor (”barnebek”). - Later when baby gets mothers own milk the stool is soft, yellow, smells a bit like mustard (”morsmelk-bæsj”). Up to 10-14 days between each time they pass stool may be normal.
155
Not normal! * Persistent vomiting. * Vomiting long time after feeds. * Bile stained (green) or feculent (brown) vomiting. * Not passing meconium within 48 h after birth. * Visible peristalsis and abdominal distension.
Intestinal obstruction • Atresia/stenosis – Oesophagus, duodenum, small bowel and rectum/anus. • Intestinal malrotation – incomplete duodenal obstruction (± volvulus) • Hirschsprung’s disease • Pyloric stenosis – Symptoms 2-8 weeks of age • Intraluminal obstruction – Meconium ileus (CF?)
156
Oesophageal atresia and tracheo-oesophageal fistula. Frothy saliva from the mouth associated with coughing, choking and cyanotic episodes. At least 50% will also have other abnormalities. High mortality!
Congenital Anomalies of the Kidney and the Urinary Tract (CAKUT) • HYDRONEPHROSIS; the most common congenital condition detected by prenatal ULTRASOUND. – Mild degrees; uncertain clinical importance. Transient dilatation of the upper urinary tract/renal pelvis is common in mid trimester. • Abnormalities more common in boys. Specific problems - Multicystic dysplastic kidney - Unilateral renal agenesis (1: 1000-1500) ``` Unspecific problems “Dilatation of renal pelvis”: - Normal/transient - Stenosis in pyeloureteric junction - Stenosis in vesicoureteric junction - Vesicoureteric reflux ``` Bilateral problems - Oligo-hydramnios? * 90% of amniotic fluid is fetal urine - Bilateral renal agenesis (Potter syndrome) - Posterior urethral valves (PUV) * May damage the kidneys
157
Potter`s syndrome Bilateral renal agenesis/ polycystic kidney leads to oligohydramnios and pulmonary hypoplasia. Special facial appearance; flat nose, low set ears and joint contractures. Usually fatal due to severely hypoplastic lungs
Hypospadia - Urethral meatus abnormally placed Epispadia Abnormal development of cloacal membrane and incomplete midline fusio.n (epispadia; a milder degree of bladder extrophy) Much more complicated than hypospadia! Bladder extrophy Bladder opens onto the abdominal wall, marked separation of pubic bones and epispadia of the genitalia
158
Hydrocele - Clinical diagnosis - Transillumination!
Disorders of sex development (DSD) • An extremely distressing situation for the parents when the sex of their child is not easily determined – A delicate task to meet the family correct • Gender assignment should be made after thorough investigation. Never guess in front of parents! • When talking to parents initially say ”your child”. – Never say ”he” or ”she” until gender assignment is clarified • Consider referral to specialized multidisciplinary team – Norway: Bergen or Oslo.
159
CNS malformations (Brain and medulla) • Spina bifida - occulta - meningocele - myelomeningocele * Disorders of migration * Hydrocephalus * Examples of other brain malformations
Myelomeningocele - MMC • Prenatal diagnosis. – Large defects are diagnosed prenatally. • Often hydrocephalus and a Arnold Chiari malformation (= downward displacement of the cerebellar tonsils through foramen magnum). • Variable sensory and motor impairment. • “Always” problems with bladder and bowel control – Neurogenic bladder • Orthopaedic problems (scoliosis, hip dysplasia)
160
Brain development • Up to week 20: Neuronal proliferation (germinal matrix) and neuronal migration to cortex. • Injury may cause neuronal migration disorders – Lissencephaly – Pachygyria – Polymicrogyria
Hydrocephalus Clinical presentation - Large head circumference (HC) > 97.5 p (> 2SD) - Anterior fontanel is large or bulging - Cranial sutures are widely separated - Initially vague clinical symptoms - HC grows fast - Intracranial pressure will gradually increase and cause failure to thrive and vomiting Microcephaly (HC < 2 SD) – Associated with poor neurodevelopmental outcome – Zika virus infection
161
Developmental dysplasia of the hip • Girls > boys (4 : 1) • Risk factors: breech presentation, foot deformities and positive family history • ”Unstable hips” on examination at birth in 2% of all infants, only 10% of these develop luxation • If pos. risk factors or pos. clinical findings (Ortolani test) an ultrasound is performed: – Normal – Immature (observe and control) – Dysplasia (Freykas pillow)
Talipes (Pes equinovarus - club foot) • 1 out of 1000 newborn infants • Boys > girls (2 : 1) – Inversion at subtalar joint – Adduction at talonavicular joint – Equinus at ankle joint; plantar-flexion position, making the foot tend towards toe walking • Treatment should start relatively early – Stretching – Serial above-knee plaster casts changed on a weekly basis – Achilles tenotomy and other operations often necessary
162
”Physical activity is defined as any bodily movement produced by skeletal muscles that requires energy expenditure ” (WHO) • Physical inactivity (lack of physical activity) has been identified as the fourth leading risk factor for global mortality (6% of deaths globally). The term "physical activity" should not be mistaken with "exercise". Exercise, is a subcategory of physical activity that is planned, structured, repetitive, and purposeful in the sense that the improvement or maintenance of one or more components of physical fitness is the objective.
Norway tops the european rates regarding inactivity levels. * 24 % of 16-24 year-olds have ”screentime” > 7h/day. * 50 % of all norwegian children walk or bike to school. * 6-10 % aged 7-10 has motorical problems. * 80 % of adolescents worldwide does not meet the guidelines of recommended PA. Age between 6-10 is the most vulnerable period for developing obesity due to increased fat storage. -> Tracking
163
Children and adolescents should do 60 minutes (1 hour) or more of physical activity daily. - Aerobic Activities: Most of the 60 or more minutes per day should be either moderate- or vigorous-intensity aerobic physical activity. Include vigorous-intensity physical activity at least 3 days per week. - Muscle-strengthening Activities: Include muscle-strengthening physical activity on at least 3 days of the week, as part of the 60 or more minutes. - Bone-strengthening Activities: Include bone-strengthening physical activity on at least 3 days of the week, as part of the 60 or more minutes.
Limit “Screen Time” • The Norwegian Directorate of Health recommends less than 2 hours of media time per day. - Television - Computer - Movies/DVDs - Video games • Turn commercial breaks into activity breaks • Turn off the television during mealtimes • Do not use screen time as a reward or punishment
164
Osgood-Schlatters disease * Most common cause of anterior knee pain in young athletes. (11 - 15 year) * Caused by repetetive tractions from the patellar tendon to the apophysis of tub. tibiae. Symptoms and signs: - Pain when in activity - Tenderness to palpation - 20-30 % bilateral Treatment: - Conservative; modify training. - Tape, brace

166
Spondylolysis • 50 % of backpain in young are caused by sponylolysis. 5-8 % of western people have this condition. * M:W 3:1 * Stressfracture i pars interarticularis * Usually activityrelated and occurs from repetitive hyperextension - Often seen in gymnastics * NB! Female-Athlete triad
Symptoms: - Lower back pain Diagnostics • One-legged hyperextension test • MRI Spondylolisthesis • Defined as forward translation of one vertebral segment over the one beneath it. • approximately 15 % of individuals with a pars interarticularis lesion have progression to spondylolisthesis. • most common at L5-S1 (90%) in pediatric population. • Grade I-IV.
167
Key points = learning objectives Is this rash dangerous? • Petecchiae: MC-sepsis, thrombocytopenia Common, usually not dangenous • Maculae Fever and macular exanthema • Usually a benign viral infection
Description of rash • Types of rash – Macula, papula, vesicula, pustula, cruste, – Petechiae/purpura * Size of primary elements * Color and color intensity * Confluent? Single elements? * Localization
168
3 day fever, then the rash - Exanthema subitum Exanthema, fever, joint pain • Exanthema infectiosum • Parvovirus Petecchiae. Probable meningococcal sepsis Fever and macular exanthema - Enterovirus Coxackevirus
Trombocytopenia in children Petechia / nose bleeding when trc < 10 Bleeding in the skin. Does not disappear on pressure Vasculitis caused by virus. Difficult differential diagnosis to meningococcal sepsis. Does not disappear on pressure Henoch-Schønleins purpura - ITP - Leucemia - Aplastic anaemia - Treatment with cytostatic drugs - Sepsis / DIC - HUS
169
Growth The genetics Mid-parental height (MPH): Boys = (fathers height + mothers height + 13)/2 Piker = (mothers height + fathers height - 13)/2 • +/- 10 cm = +/- 2 SD Normal growth: Prenatal: approx 1.2-1.5 cm/week with Peak around week 18: 2.5 cm/week- and slowing to 0.5 cm/week before birth. Infancy: rapid but decelerating, approx 25 cm first year. Childhood: relatively constant, approx 5-6 cm per year. Puberty: growth acceleration “on top” of a decelerating childhood growth.
Endocrine regulation of growth - Fetal growth: mainly nutrition and insulin. - Infancy growth: nutrition and thyroid hormone. - Childhood growth: growth hormone (GH) and thyroid hormone. - Puberty growth: testosterone or estrogen. Growth hormone - Predominant regulator of childhood growth. - GH secretion is pulsatile, mostly during night. - Stimulates IGF-1 production in liver, and binds to IGFBP3 + ALS (Acid labile subunit) in the circulation. - IGF-1 has the most effect on linear growth, although GH receptors in the epiphyses also has some effect on growth. - GH stimulates lipolysis /inhibits lipogenesis. - GH increases amino acid uptake in muscle.

Turner syndrome - 45 X0 - Many have genetic mosaicism 45X0/46XX, 45 X0/47XXY, 45 X0/46 XY or X chromosome structural abnormalities. Characteristics: - Lymphedema at birth - Short ! - Lack of or incomplete puberty - Neck skinfold/webbing ! - Increased mammillary distanse - cubitus valgus +++
Medical evaluation in primary care ``` Clinical exam incl pubertal stage Blood samples - Hb, SR, electrolytes, kreat - Tissue transglutaminase, folate, ferritin, Calcium, - ALP, vitamin D - FT4, TSH ``` In hospital - IGF-1, IGFBP3 - Chromosomes in girls - Bone age - Other genetic tests - Total body X-ray if bone dysplasia is suspected - GH secretion tests - Confirmation of chronic illness
172
Klinefelter syndrome - 47 XXY - 1/600 boys - Tendency to tall stature - Many un-diagnosed - 5-10% of male infertility - Learning disabilities, delayed puberty, small testicles
Marfan syndrome - Autosomal dominant connective tissue disease - Tall, increased armspan, hyper extensible joints, dislocation of the lens, aortic root dilatation.
173
HPG axis - Hypothalamic-pituitary – gonadal axis - Classical endocrine feedback system - Modulated by peptides from nucleus arcuatus and periventricularis
Endocrinology of puberty LH/FSH peak in pregnancy week 20-24. FSH/LH peak about 8-10 weeks after birth – ”mini puberty” Quiescence in childhood due to active suppression First sign is increased GnRH signalling and low but measurable levels of FSH/LH - Genetics - Androgens - Body mass/ leptin
174
Adrenarche - Shift in adrenal glands to produce DHEA - Starts around age 6 - Small growth spurt, sweat start to smell, few pubic hairs can be seen, maybe acne - ”Skin puberty”
Timing of puberty Girls usually 1-2 years ahead of the boys. First sign (90 % B2, 10 % P2) 9-13 år. Menarche 13.3 år. Average of 2 years from Tanner 2 to menarche Boys: Testis > 4 ml 11-15 år
175
Physical changes in girls Thelarche: breast enlargement Pubarche: pubic or axillary hair Menarche: first menstruation Growth spurt Female fat deposition Uterus changes
Physical changes in boys Testicular enlargement, TV > 4 ml or long axis length > 2.5 cm Pubarche normally within next year. Penile/scrotal growth. Transition to adult voice around age 14. Facial hair around age 15.
176
Hypogonadotropic hypogonadism ``` Kallmann syndrome – anosmia, midline defects CNS irradiation Tumor Prader Willi Syndrome CNS malformations ``` Treatment: medical puberty when time is right Girls - Turner syndrome ! - Ovarian failure due to chemotherapy or irradiation. - Autoimmune ovarial failure. Boys - Klinefelter syndrome - Anorchia - Orchitis due to mumps - Chemotherapy / irradiation
Evaluation delayed puberty ``` History and clinical exam Bone age FSH/LH, prolaktin, FT4/TSH, hematology, SR, tissue transglutaminase, chromosome. Ultrasound in girls. LHRH test. MRI brain. ``` Treatment delayed puerty: Goal: Mimic sexhormone levels in normal puberty, mimic normal progression through puberty. Boys: increasing doses of testosterone. Girls: increasing doses of estrogen + gestagen after about 2 years for menarche.
177
Atopisk dermatitt ``` 0-6 months - Atopic dermatitis 6-12 months - Food Allergy - Viral induced asthma School age - Airway allergies - Exercise induced asthma ``` ``` AD is very common Prevalence: 0-3 years: 30% 7 years: 15% 18 years: 10% North > South Comorbidity with asthma and allergies The atopic march ``` 4 clinical features of AD - Dry skin - Itching - Inflammation - Infection
AD – Location and Recovery Infants: Cheaks/face and most of body Children: Inside elbows, knees, wrists of hands and ankles, around ears and eyes. Spontanous regression by 2-3 years of age is common. 90% recovery by 20 years of age. ``` AD and Heritage 70 % have atopic disease in the family > 50% risk for AD if both parents have atopic disease Not related to a single gene. - Many different genes (and phenotypes). - Epigenetics seems to be important. ``` Parents search for allergens, however: Allergy is not the most common trigger for AD. 1/3 of 0-3 years of age exacerbate due to allergy. Food allergens (Egg, milk, wheat, soy). Airborne allergens (pollen, pets). Allergy is less important > 3 years of age. Reduced skin barrier due to AD, facilitates sensibilisation to allergens.
178
Fatty skin - Seborrhoic ``` Large sebaceous glands Large pores Fatty, gleary skin Blood wessels dilate Read skin ```
Dry skin - (Atopic) ``` Small sebaceous glands Small pores Little sebaceous matter Blood wessels tend to contract. Pale skin ```
179
SABA = Short Acting β-2 Agonist (e.g. Ventoline®, Bricanyl®, Salbutamol®, Airomir®) LABA = Long Acting β-2 Agonist (e.g. Serevent®, Oxis ®) ICS = Inhaled Cortico Steroids ( e.g. Flutide®, Pulmicort®) LTRA = Leukotriene Receptor Antagonists (e.g. Singulair ®) ICS and LABA can be combined in the same device and are then often given a new name E.g Serevent + Flutide = Seretide® and Pulmicort + Oxis = Symbicort®
SpO2 > 92 % = Serious acute asthma
180
Allergy: Specific IgE-mediated immunologic reaction to an allergen - Cows milk protein allergy Intolerance: Not mediated via the specific immune system - Lactose intolerance
Allergic Atopic Eczema - Atopic Eczema is most often not triggered by an allergen. - 30% of small children with exzema. - Food most common (egg, milk, soy, wheat, nuts, peanuts, fish). - May be triggered by airborne allergens (pollen, pets).
