brachial pulse
what is oppositional defiant disorder
paed psychiatric diagnosis in which children show persistent defiant and hostile behaviour towards figures of authority, like a parent or teacher. The behaviour is not significant enough to be a serious disability in social functioning, unlike the more serious diagnosis of conduct disorder.
what is conduct disorder
examples of problems
Conduct disorder is a diagnosis given to patients under the age of 18 years old who show behaviour and attitudes that
continuously
disrespect and violate the rights of other people. It is more common in males.
continuously - conduct
Common problems include:
physical agression
destructive behaviour
stealing
1 - A 12 year old boy is taken to the GP by his mother, asking for help because her son is “out of control”. He is frequently in trouble for physical fighting at school, lighting fires in the school and severe temper tantrums when things do not go his way. He has been found shoplifting from local stores and last week his mother found him throwing stones at their cat, which she felt could have caused serious injury if she had not stopped him.
2 - An 11 year old girl is brought to the GP because her mother is ‘beyond despair with her’.
The mother reports that her daughter is consistently hostile and angry towards her. She always does the opposite of what she asks her to do, shouts at her mother if she tries to get her to do anything, and insults her mother at every opportunity. Otherwise, the girl is fit and well. She has not yet reached puberty. She is getting on well at school, although occasionally her report card mentions that she talks back to teachers. She has lots of friends and gets on well with her younger brother.
what is conduct and what is oppositional defiant disorder
Conduct disorder
This boy presents with a history in keeping with conduct disorder, characterised by a repetitive and persistent pattern of dissocial, aggressive or defiant behaviour. Common presentations include stealing, bullying, lying, fighting, fire-setting and cruelty to animals. Temper tantrums which are not age-appropriate can also be seen
Oppositional defiant disorder
This 11 year old girl shows persistent defiant and hostile behaviour towards her mother, a figure of authority. Given that this is having an impact on their relationship, but she is otherwise getting on well socially with her peers and performing well at school, there is no significant debility that would be more consistent with conduct disorder
intersusseption imaging modality and what will it see
Abdominal ultrasound will demonstrate the target/doughnut sign - concentric rings of hyper- and hypo- echogenicity.
A 3 month old boy, corrected for gestational age, born in May, with trisomy 21 has a ventricular septal defect. He is currently on a high-calorie nastrogastric feed and furosemide.
What prophylactic therapy is indicated for this patient?
Palivizumab
This is a premature boy under the age of six months (corrected) approaching bronchiolitis season. He has significant acyanotic heart disease, requiring furosemide to prevent from him being symptomatic. He meets the indications for RSV prophylaxis. Palivizumab is a monoclonal antibody that minimises the risk of infection by RSV. It is given subcutaneously once a month during bronchiolitis season
A 14 year old boy with learning difficulties presents to the GP with his parents for follow up of anxiety. He has suffered from severe anxiety in social situations since early childhood, and often bites his hands to help himself cope. He also has epilepsy which is well controlled on valproic acid.
On inspection, he appears well but will not make eye contact with you. He has a long thin face, a large jaw and his ears stick out prominently. He repeats everything you say to him. His chest is clear to auscultation. Heart sounds I + II are present, with a 2/6 systolic murmur with mid-systolic click loudest at the apex.

congential heart block caused by
linked to prescene of what antibodies
It is most commonly associated with maternal Systemic Lupus Erythematosus. It is linked to the presence of maternal anti-Ro and/or anti-La antibodies, although the exact mechanism is poorly understood.
Symptoms of heart block in children can vary, from asymptomatic to severe heart failure
Neonates may be noted to be bradycardic or be in circulatory shock
Most commonly, children do not have symptoms for the first few years of life, and then present with pre-syncope (feeling faint) and syncope (fainting)
Management
If children with heart block are symptomatic, they will require a pacemaker.
A six-year old girl presents to ED with her mother, who is worried. Over the last week and a half the child has had a fever with a headache. In the last two days the child has developed diarrhoea and a red rash covering her cheeks that spares the nasolabial folds. She is also complaining of pain in her knees. The child has been otherwise well, and has completed her vaccines. What is the most likely diagnosis?
rash that spares nasolabial folds
slapped cheek - lace like rash
complciations
Red cell aplasia
Parvovirus infection also reduces erythropoiesis.
especially sickle cell anaemia and hereditary spherocytosis that rely on erythropoiesis, infection can precipitate a severe anaemia, causing an aplastic crisis
Infection in the first half of pregnancy can also cause severe foetal anaemia that can precipitate hydrops foetalis and subsequent miscarriage
Cardiomyopathy

hydrops fetalis
A 14-year-old boy presents to the GP with abdominal pain, arthralgia and a non-blanching purpuric rash on his shins. He is normally fit and well; however, for the last week he has been suffering from coryzal symptoms. The doctor suspects a diagnosis of Henoch-Schonlein Purpura.
Which of the following is the next best step in the management of this patient?
urine dip
classic triad of symptoms of HSP
arthralgia
abdo pain
purpura - extensor surfaces
factors affecting foetal growth leading to intrauterine growth restriction
Maternal BMI and nutritional status (including poor weight gain during pregnancy)
Co-morbidities such as diabetes, anaemia, hypertension, infection, sickle cell anaemia, pulmonary or cardiovascular disease, renal disease, coeliac disease
Cigarette smoking, alcohol and substance abuse
Structural uterine malformations
Chromosomal defects
Multiple pregnancy
Vertically transmitted infection (e.g. CMV, rubella, toxoplasmosis)
Utero-placental insufficiency
Pre-eclampsia
An 18-month-old girl is brought into the Paediatric Emergency Department following a witnessed seizure. The girl’s mother explains that she was crying inconsolably prior to the event. During the episode, the girl’s mother describes seeing her collapse, followed by her first going limp, then having some rhythmic movements of her hands and feet and seeing a slight blue tinge in her face. The episode lasted for 30 s. Following this, the girl’s mother says she was ‘completely fine’ and was running around as if nothing had happened.
Given the most likely diagnosis, which of the following would be the definitive management plan?
reassure and discharge
breath holding spell
what is stridor
musical noise heard during inspiration from partial obstruction of the larynx or large airways.
croup, epiglottisi, and trachiestiis
differnce between croup epilgootis and bacterial tracheitis
Croup
The child would present with cough and coryzal symptoms and in moderate and severe cases with inspiratory stridor.
The symptoms will worsen at night and this is the most common time for these patients to be brought into A&E.
Epiglottitis
The child classically presents with a high temperature, inspiratory stridor and is struggling to breath and drooling.
They are normally very irritable and it is not advisable to disturb these children as they can cry which will result in an obtunded airway.
Bacterial Tracheitis
The child presents with symptoms which are intermediary between those of croup and epiglottitis.
Patients may present with difficulty breathing and shortness of breath combined with a temperature.

An 8 year old boy presents to the GP with a runny nose, sore throat and cough that he has had for the past 2 days.
He reports feeling OK and asks if he can play football this afternoon, but his mother is worried. He is normally fit and well.
He appears well with a respiratory rate of 20 and saturations of 100%. On ENT examination, his throat is pink with no swelling or exudate of the tonsils, and his tympanic membranes are visible with no bulging or effusion. On auscultation of the chest, you hear a soft systolic murmur at the left sternal edge. The murmur does not radiate and there is no thrill on palpation. He has never been noted to have a murmur before.
What is the most appropriate management for this murmur?
if persists after this what do you do?
Review again in 2 weeks
This patient is presenting to the GP with a common cold and a soft systolic murmur at the left sternal edge. This is most likely to be an innocent murmur. Innocent murmurs are very common in children (up to 30% of children at some point), and can be precipitated by febrile illness. As this child currently has a mild viral infection, the best option is to review the murmur in a few weeks once the infection has resolved, to see if the murmur has disappeared with the infection. The infection is likely to be a mild viral upper respiratory tract infection, as evidenced by a lack of tonsillar exudate, angry red throat and no sign of ear infection (bulging tympanic membrane with effusion)
Soft
Systolic (note: all diastolic murmurs are pathological)
Sensitive (changes with the child’s position / alongside respiration)
Short (not holosystolic)
Single (no additional sounds)
Small (localised, non-radiating)

A 1 year old girl is brought in to A/E by her parents as they are concerned about her breathing. She has been feeling unwell with the flu over the last few days. The parents describe a barking cough. They think she has had all her immunisations. She has a high grade fever. A constant high-pitched sound on inspiration can be heard and she has a hoarse voice.
Humidified oxygen, dexamethasone and nebulised adrenaline is given. The symptoms do not improve.
What is the most likely diagnosis?
bacterial trachietis
A 9 month old boy is rushed into the paediatric emergency department with an ongoing seizure which has failed to terminate following initial treatment with buccal midazolam. Following a full DRABC assessment and further treatment with IV lorazepam his seizure is successfully terminated and he is transferred to the paediatric high dependency unit for further management. On review it is noted that he has 4 large hypo pigmented macules each measuring over 2cm in diameter on his back and torso. There is also noted to be angiofibromas on the nose. Ophthalmological examination reveals the presence of a small retinal hamartoma in the right eye. An electroencephalogram (EEG) is requested and shows evidence of hypsarrhythmia. An echocardiogram comes back as normal.
The paediatric consultant requests an MRI head and in the meantime asks you what is most likely to be the diagnosis?
Tuberous sclerosis complex
Correct. Tuberous sclerosis complex is the most likely diagnosis given the history and you would expect the MRI head to show evidence of benign tubers in the cerebral hemispheres. The hypo pigmented macules described (ash leaf spots) and angiofibromas of the nose are all characteristic of tuberous sclerosis. Tuberous sclerosis is also associated with epilepsy and the hypsarrhythmia if a classic finding on electroencephalogram
42%
The disease has 2 genetic loci:
TSC1, found on chromosome 9q34 - hamartin;
TSC2, found on chromosome 16p13 - tuberin;
The clinical phenotype can result from a mutation in either of these genes.
Clinical features
Infantile spasms with hypsarrhythmia seen on electroencephalogram
Skin: Ash leaf macules; Shagreen patches; facial angiofibromas; subungual fibromas
Neurological/Cognitive: Learning disabilities; Sub-ependymal nodes; Seizures/Epilepsy
Renal: Angiomyolipomas
Cardiac: Cardiac rhabdomyomas
Management
Angiofibromas <2mm in diameter will respond to laser therapy
Angiofibromas >2mm in diameter require dermabrasion or surgical resection
Many patients with renal disease will require anti-hypertensive therapy
Tubers should be regularly imaged and may require surgical resection

A 2 month old baby boy is seen by the GP because of difficulty breastfeeding and poor weight gain.
The mother reports that although the baby has a good latch and a strong suck, he gets really tired and out of breath after a few minutes of feeding. This has been getting worse since he was about a week old. He was born by spontaneous vaginal delivery at 39+6 weeks after a normal pregnancy and antenatal scans.
On inspection, he is active, alert and smiley. There is a 2/6 pan-systolic murmur loudest at the lower left sternal edge. The lung fields are clear to auscultation. His abdomen is soft with no organomegaly. His temperature is 36.9 degrees. Plotting his weight on his growth chart shows he has dropped two centiles between 6 and 8 weeks of life.
Which of the following is the best investigation to definitively diagnose this patient’s underlying condition?
left lower sternal edge pansystolic murmur - VSD
echo
A 2 year old girl is brought to A&E at night with a fever and noisy breathing. Her parents say she has had a cough and a runny nose for the last 2 days.
On examination, there is a harsh rasping sound on inspiration. Her respiratory rate is 36, oxygen saturations are 95% and temperature is 38.9 degrees.
What pathogen is most commonly responsible for the most likely diagnosis?
parainfluenze croup
epiglotois caused by
haemophilus influenza
