Viral cause (parainfluenza usually)
note majority of cases mild but if needed…
- oral dexamethasone 0.15 mg/ kg as a single dose
- Nebulised Adrenaline 5mls 1:1000 (mod or severe)
- senior input
7
Q
symptoms and management of foreign body aspiration
A
sudden onset of respiratory distress associated with coughing, gagging, or stridor. Unilateral wheezing suggests partial obstruction of the main or distal bronchi
management with flexible bronchoscopy or rigid if fails
8
Q
signs of respiratory distress
A
- increased RR
- stridor
- tracheal tug; retraction at the suprasternal notch
- intercostal recession
- subcostal recession
- head bobbing
- grunting
- posture
impending respiratory failure and exhaustion will develop a low respiratory rate (for their age) and breath sounds including added sounds can diminish
9
Q
differentials child in upper respiratory distress

Viral Croup
Epiglottitis (unlikely with haemophilia influenza vaccine)
Foreign body aspiration
Anaphylaxis
Bacterial tracheitis
10
Q
laryngeal capillary haemangioma

slowly progressive airway obstruction / stridor since birth, particularly if the child has other capillary haemangiomas
11
Q
gastro-oesophageal reflux disease in infants
A
silent symptoms or intermittent distress commonly after feeds and on lying flat, intermittent breathing difficulty with symptoms including stridor, episodes of colour change and / or recurrent chest infections, and behavioural changes such as back arching
12
Q

soft stridor that worsens with feeds
monitor feeding and growth
13
Q
epiglottitis
A
very rare cause of airway obstruction seen most in children 2-7
sudden onset of distressed child with muffled cough and voice, normal temp, drooling and leaning forward
needs emergency airway management
usually bacterial cause
14
Q

A
differenital for epiglottis
younger age; 6 months to 14 months
fever present
sudden onset
hoarse voice and cough
drooling
needs emergency airway
broad spec Abx once airway secured
15
Q

child pale and sweating (hypotensive), wheeze, stridor
16
Q
what type of allergic reaction is a food allergy
A
type I hypersensitivity
17
Q
sensitisation to allergen
A
for an allergy to occur a child must have previously encountered the allergen
Following exposure to an antigen the protein causes cross binding of two bound IgE molecules on the Mast Cell or Basophil surface. This process results in degranulation of the Mast Cell.
Histamine is released immediately causing the reaction
18
Q
actions of histamine
A
localised irritation
vasodilation
bronchoconstriction
endothelial cell separation - resulting in urticarial rash
19
Q
criteria for prescribing an Adrenaline Pen
A
- History of Anaphylaxis
- Previous cardiovascular / Respiratory involvement
- Evidence of airway obstruction
- Poorly controlled Asthma requiring regular inhaled corticosteroids
- Reaction to a small amount of allergen
- Ease of allergen avoidance
in less severe allergy, having antihistamine available can be sufficient

skin - saltier sweat
liver
pancreas - exocrine and endocrine insufficiency
intestines - malabsorption
reproductive organs
58

recurrent respiratory problems (not in firth few months)
64
fetal circulation shunts
ductus arteriosus - between pulmonary artery and aorta to bypass lungs
foramen ovale - between R to L atria
ductus venosus - between umbilical vein and inferior vena cava to bypass liver
ducts are aided by high pulmonary vascular resistance in the foetus
65
how do fetal shunts change at birth
at first breath - alveoli fill with air and vascular resistance of the pulmonary circulation decreases
LA pressure exceeds RA pressure and the foramen ovale closes
circulating prostaglandins drop due to increased blood oxygenation - ductus arteriosus closes
ductus venous closes after cord clamped
66
PDA
- diagnosis
- management
may be picked up at birth with a murmur
can also present with failure to thrive, SoB, difficulty feeding - the L-R shunt causes increased pul pressure and HF
needs echo to diagnose
typically monitored until 1 year by which point may have closed or catheter surgery is performed
67
ASD symptoms/complicaitons
L-R shunt causes right heart strain and pul hypertension but is acyanotic because blood is always being oxygenated
eventually in Eisenmenger syndrome the pul pressure can exceed systemic and the shunt reverses to R-L causing cyanosis
murmur:mid-systolic, crescendo-decrescendo murmur loudest at the upper left sternal border with a fixed split second heart sound
may be picked up antenatally or later with symptoms/complciations
other complications are AF, stroke
68
VSD presentation
may be picked up antenatally or a murmur at newborn baby check
can also present with symptoms such as Poor feeding
Dyspnoea
Tachypnoea
Failure to thrive
69
CXR tetralogy of fallot
typically boot shaped heart due to RVH
70
"Tet spells" tetralogy of fallot
intermittent symptomatic periods where the right to left shunt becomes temporarily worsened, precipitating a cyanotic episode
usually when a child is physically exerting themselves, crying, laughing etc.
management: can try knees to chest/squatting. if failed
- oxygen
- IV fluids
- beta blockers/adrenaline/morphine
71
tetralogy of fallot management
prostaglandins can maintain ductus arteriosus
then heart surgery needed - mortality from surgery 5%
72
differentiating viral induced wheeze and asthma
factors favouring asthma
- personal or FHx of atopy
- interval symptoms (between viral infections ) of coughing at night, when playing or in cold
73
management of acute asthma child

74
long term medical asthma therapy age <5
Start a short-acting beta-2 agonist inhaler (e.g. salbutamol) as required
Add a low dose corticosteroid inhaler or a leukotriene antagonist (i.e. oral montelukast)
Add the other option from step 2.
Refer to a specialist.
75

Start a short-acting beta-2 agonist inhaler (e.g. salbutamol) as required
Add a regular low dose corticosteroid inhaler
Add a long-acting beta-2 agonist inhaler (e.g. salmeterol). Continue salmeterol only if the patient has a good response.
Titrate up the corticosteroid inhaler to a medium dose. Consider adding:
Oral leukotriene receptor antagonist (e.g. montelukast)
Oral theophylline
Increase the dose of the inhaled corticosteroid to a high dose.
Referral to a specialist. They may require daily oral steroids.
76
whooping cough symptoms
URTI caused by pertussis (children and pregnant women are vaccinated against)
typically starts with mild coryzal symptoms, a low grade fever and possibly a mild dry cough.
more severe coughing fits start after a week or more
77
whooping cough diagnosis
A nasopharyngeal or nasal swab with PCR testing or bacterial culture can confirm the diagnosis within 2 to 3 weeks
later can be tested for anti-pertussis toxin immunoglobulin G
78
whooping cough management
notifiable disease
management usually supportive
macrolide Abx can be helpful in early stages
close contacts are given prophylactic Abx
usually resolves in 8 weeks but can be long lasting and key complication is bronchiectasis

111
short stature; approach to diagnosing cause
general Hx + Hx of family
?diarrhoea ?abdo pain ?energy
examination: ?dysmorphic, ?limb size, ?skin lesions
parental heights + mid parental centile
blood pressure - renal failure can be missed cause
investigations; thyroid, creatinine, bone and liver profiles, FBC, CRP, glucose, coeliac screen
chromosomes esp girl ?turners
bone age vs actual age; is there just delay
112
follow up short stature
usually not immediate medical diagnosis
follow up every 4 months and if cause identified can treat
keep safeguarding in mind
113
first signs of puberty girls/boys
girls; breast development then pubic hair
boys; testicular enlargement followed by genital changes. later age than girls
114
definition of delay puberty
no signs age 14 in boy or age 13 in girl
in boys testosterone to kickstart puberty sometimes offered
115
precocious puberty
any signs before age of 8 in girl and 9 in boy
more likely to be pathological if under age 6
can be psychological distressing and can stunt adult height
can offer blockade with GnRH antagonist e.g. zoladex every 12 weeks injection
116
thyroid disorders causing stunted growth
congenital hypothyroidism - should be detected on newborn heel prick test
2/3 of these have absent or ectopic thyroid gland - need lifelong replacement
other 1/3 gland is present but not producing - usually still needs replacing but sometimes starts producing thyroxine; trial cessation at age 3
acquired hypothyroidism - autoimmune condition can be seen in adolescent females
117
physical features of dehydration in an infant
Sunken anterior fontanelle
dry mucous membrane
tachycardia
reduced capillary refill time

whooping cough
132
what is a fluid challenge
if at risk of dehydration, give oral bolus of rehydration solution frequently in small amounts
5ml/kg of ORS after each large watery stool in children who are at risk of dehydration - consider giving via NG
continue to monitor input and output
continue breast feeding and other milk feeds
133
what children are at risk of dehydration
low birth weight, age less than 1 year, had more than 2 vomiting episodes and more than 5 diarrhoeal episodes in the previous 24 hours
134
usual duration of diarrhoea illness in children + how to manage simple illness
5-7 days and in most children, it stops in 2 weeks. The family should continue encouraging intake of usual fluids (breast milk or formula) and give 5ml/kg of ORS after passage or each loose stool
not attend nursery until 48 hours after last vomit or diarrhoea
135
safety net simple gastroenteritis
contact healthcare professionals if child becomes unwell, appears pale/mottled, starts to vomit again (vomiting should not last longer than 3 days) has decreased urine output/wet nappies, irritable/lethargic and has cold extremities.
136
mechanisms of infectious diarrhoea
Secretory mechanism: ↓ absorption, ↑ secretion & electrolyte transport --> Watery stool. caused by Cholera, E. coli , Clostridium difficile and cryptosporidium (in HIV infection)
Mucosal Invasion: Inflammation, ↓ mucosal surface area and/or colonic reabsorption and ↑ motility --> stool with Blood and ↑ WBC’s. Caused by Rotavirus, campylobacter, Salmonella, shigella, Yersinia
137
features of a gastroenteritis that suggest another diagnosis
- Fever – temperature >38 degrees or higher in children younger than 3 months & >39 degrees or higher in children aged 3 months and older
- Tachypnoea
- Altered consciousness level
-Neck stiffness
- Bulging fontanelle in infants
- Non-blanching rash
- Blood and /or mucus in stool
- Bilious vomit
- Severe or localised abdominal pain
- Abdominal distension or rebound tenderness
138
mechanisms/causes of dehydration
isonatraemic - proportional loss of water and sodium
hyponatraemic - intake of large quantity of water, fall in serum sodium, resulting is shift of water form extracellular to intracellular compartment causes brain oedema and marked extracellular dehydration and shock
hypernatraemic - water loss exceeds the sodium loss with resultant increase in plasma sodium concentration. This can happen when there is low sodium diarrhoea or high insensible water loss. There is shift of water from intracellular to extracellular compartment and therefore less signs of dehydration and more features of hypertonia, hyperreflexia, convulsions, drowsiness

main groups of inborn errors of metabolism causing hyperammoniaemia
urea cycle disorders and the organic acidaemias
221
Urea cycle disorders
ammonia level is markedly raised and often over 1000 micromols/L and there is liver dysfunction
blood gas often shows a respiratory alkalosis due to the ammonia acting as a respiratory stimulant
222
organic acidaemia
mixed picture of metabolic acidosis and hyperammonaemia - less high than urea cycle disroders
The first pointer to diagnosis is a metabolic acidosis that does not respond to standard fluid resuscitation and then the finding of a raised anion gap caused by the presence of the abnormal organic acid.
Methylmalonic acidaemia and propionic acidaemia are the 2 most common organic acid disorders.
223

233
how does DKA present
may initially have polyuria, polydipsia, weight loss, excessive tiredness
more specific to DKA symptoms are nausea or vomiting, abdominal pain, hyperventilation, dehydration and reduced level of consciousness
234
when should a suspected DKA be sent immediately to an acute paediatric facility (HDU)

235
DKA diagnostic criteria
1. Acidosis (indicated by blood pH below 7.3 or plasma bicarbonate below 18 mmol/litre) and
2. Ketonaemia (indicated by blood beta-hydroxybutyrate above 3 mmol/litre
Diagnose severe DKA in children and young people with DKA who have a blood pH below 7.1.
236
what is the main cause of morbidity and mortality in childhood DKA
from cerebral oedema due to rapid correction
The aim of therapy is very gentle and slow correction to avoid cerebral oedema
237
initial management DKA
- inform senior clinician
- explain to child and parents
- fixed rate insulin infusion
- IV fluids
- may need potassium
- avoid hypo by adding dextrose when glucose is coming down
- monitor for signs of cerebral oedema
can give O2, consider ABX and consider NG tube
238
what is Kussmaul breathing
deep and labored breathing pattern often associated with severe metabolic acidosis, particularly diabetic ketoacidosis (DKA) but also kidney failure.
In metabolic acidosis, breathing is first rapid and shallow but as acidosis worsens, breathing gradually becomes deep, labored and gasping.
It is this latter type of breathing pattern that is referred to as Kussmaul breathing.
239
what needs recording once DKA diagnosed
blood gas - pH and pCO2, lactate
monitor ketones
level of consciouss
vital signs
clinical evidence of dehydration + weight
plasma sodium, potassium, urea and creatinine plasma bicarbonate
240
when should you think about sepsis in a child with DKA
has any of the following: fever or hypothermia, hypotension, refractory acidosis, lactic acidosis.
241
what fluids and when should be given in DKA
how much
only give oral fluids if alert, not nauseated or vomiting, and not clinically dehydrated
otherwise give IV and if IV don't let them have oral until ketosis is resolving
give the fluid gradually - not a bolus unless can consider in severe
Use 0.9% sodium chloride without added glucose until the plasma glucose concentration is below 14 mmol/litre.
Ensure that all fluids (except any initial bolus) administered to children and young people with DKA contain 40 mmol/litre potassium chloride, unless they have renal failure.
first 48 hours adding the estimated fluid deficit to the fluid maintenance requirement
assume if pH>7.1 5% deficit
if <7.1 assume 10% deficit
maintenance if they weigh less than 10 kg, give 2 ml/kg/hour if they weigh between 10 and 40 kg, give 1 ml/kg/hour if they weigh more than 40 kg, give a fixed volume of 40 ml/hour - this is reduced volume to avoid cerebral oedema
242
when should insulin be started and how
fixed rate insulin infusion start 1-2 hours after fluids started
use a soluble insulin infusion at a dosage between 0.05 and 0.1 units/kg/hour
243
when should normal insulin be restarted
subcut at least 30 minutes before stopping intravenous insulin. For a child or young person with DKA who is using insulin pump therapy, restart the pump at least 60 minutes before stopping intravenous insulin
244
signs of cerebral oedema
when to treat and how
assess for oedema if any of headache, agitation/irritability, increased BP or fall in HR
treat with mannitol or hypertonic sodium chloride if a child with DKA has any of deterioration in level of consciousness abnormalities of breathing pattern (for example respiratory pauses), oculomotor palsies, pupillary inequality or dilatation
escalate
245
potassium in DKA
insulin moves potassium which can lead to hypokalaemia
if falls below 3mmol/L consider temporarily suspending the insulin infusion and discuss with ICU
246
potassium in DKA
insulin moves potassium which can lead to hypokalaemia
if falls below 3mmol/L consider temporarily suspending the insulin infusion and discuss with ICU
247
basic types of insulin regimen in T1DM
1. Multiple daily injection basal–bolus insulin regimens: injections of short-acting insulin before meals, together with 1 daily injection of long-acting insulin.
2. Continuous subcutaneous insulin infusion (insulin pump therapy): a programmable pump and insulin storage device that gives a regular or continuous amount of insulin (usually a rapid-acting insulin analogue or short-acting insulin) by a subcutaneous needle or cannula.
248
optimal target ranges for short-term plasma glucose control
Fasting plasma glucose level of 4–7 mmol/litre on waking
a plasma glucose level of 4–7 mmol/litre before meals at other times of the day
a plasma glucose level of 5–9 mmol/litre after meals
a plasma glucose level of at least 5 mmol/litre when driving
measure 5x a day - more in illness or activity
249
management of mild to moderate hypoglycaemia
Give fast-acting glucose (for example, 10–20 g) by mouth and recheck BM within 15 minutes
repeat if persists
once resolved give oral complex long-acting carbohydrate to maintain blood glucose levels
250
treatment of severe hypoglycaemia
if in hospital with IV access; give 10% intravenous glucose.
if no access give intramuscular glucagon or a concentrated oral glucose solution (for example Glucogel). Do not use oral glucose solution if the level of consciousness is reduced as this could be dangerous
