Pediatric respiratory, cardiovascular and genetic cases
Select one of six paediatric case studies, explain the differential diagnosis and which is most likely and why, describe the unique characteristics of the primary diagnosis, give a treatment and management plan with appropriate dosages, and explain strategies for educating patients and families.

One case, and the requirement most posts skip
Choose one of the six cases, then read the posting instruction carefully because it asks for five distinct things and one of them is easy to miss. You must explain the differential, say which diagnosis is most likely and why, include an explanation of the unique characteristics of the disorder you identified as the primary diagnosis, give a treatment and management plan with appropriate dosages, and explain education strategies for patients and families. The unique characteristics requirement is the one most often folded into the differential and lost. It asks what makes this disorder itself rather than its nearest neighbour — the findings, course or pathophysiology that no other candidate on your list shares, and it is scored separately from the reasoning that got you to the diagnosis in the first place. Answer it as its own paragraph, and answer it comparatively — the characteristic is only unique relative to something, so name the mimic you are separating it from.
Case one is worth reading closely as the model. A 14-month-old with four days of nasal congestion and congested cough, now tachypnoeic at 58, with diminished bases, pronounced intercostal and subcostal retractions, expiratory wheeze throughout, moderate clear rhinorrhoea, normal tympanic membranes, capillary refill under three seconds, alert and smiling, and a positive RSV rapid antigen test. That is bronchiolitis, and the details matter in both directions: the wheeze and retractions establish lower airway involvement, while the alertness, smiling and normal capillary refill argue against imminent decompensation. Its unique characteristics against asthma and pneumonia are the age, the viral prodrome and the RSV result. The management answer should reflect current guidance, which is largely supportive — hydration, suctioning, oxygen if indicated — and should say what bronchiolitis does not need, since bronchodilators, corticosteroids and routine antibiotics are all recommended against. Family education then centres on expected course, feeding and the signs that warrant return.
Likely learning objectives
Inferred from the brief — check these against your own rubric.
- 01Build a differential from a paediatric respiratory, cardiovascular or genetic presentation.
- 02Justify the most likely diagnosis from the specific findings given.
- 03State the unique characteristics that separate a diagnosis from its nearest mimics.
- 04Give management consistent with current guidance, including therapies to withhold.
- 05Educate families on expected course and on the signs that warrant return.

Review before submission
Common mistakes
- Answering several cases rather than selecting one.
- Folding the unique characteristics requirement into the differential and losing it.
- Recommending bronchodilators or corticosteroids for bronchiolitis against current guidance.
- Giving management without dosages when the preparation asks for them.
- Ignoring the reassuring findings that argue against escalation.
- Writing family education as a list of facts rather than as return precautions.
Submission checklist
- One case is selected and identified.
- The differential is explained rather than listed.
- The unique characteristics have their own section.
- Management reflects current guidance, including what is not recommended.
- Dosages are given where treatment is pharmacologic.
- Family education covers expected course and return precautions.
