Primary Ciliary Dyskinesia – Board-Style Questions

What this deck covers

Primary Ciliary Dyskinesia in 18 board-style clinical cases with worked explanations. Each case gives you a clinical vignette, four options, the correct answer, and an explanation of why each of the other three is wrong, with the guideline or textbook it follows named on the answer.

Board-style teaching questions for paediatricians and trainees preparing for paediatric board, MRCPCH and licensing examinations. Written from published guidelines and standard paediatric textbooks, with the source named on every answer.

The 18 cases, in order

1. Not the usual fast breathing
2. Why the heart is misplaced
3. Her little brother
4. Too young to hold his breath
5. Why the sweat test too
6. Brushed after a cold
7. Under the microscope
8. The picture that looked fine
9. Only one change found
10. Nothing to spit out
11. A flare with a known organism
12. Can the pool replace it
13. A blocked nose every day
14. He hears us fine
15. The live injection
16. Clouds instead of cigarettes
17. Where the scan changes
18. Her own future

Diagnoses and management options tested

Across the 18 cases you are asked to choose between options such as: Needing supplemental oxygen at all, The two are unrelated and occurred by chance, Test him only if bronchiectasis appears, Brushing cannot be performed without a sweat result, Absence of the outer dynein arms, It means the brushing was taken from the wrong site, It shows X-linked transmission from his mother, Airway samples only when he is unwell with a flare, Oral clarithromycin for atypical organisms, A decongestant spray used continuously for months, Formal hearing assessment now and at intervals, Avoid all live vaccines, as his immunity is impaired, Nicotine-free vaping is harmless, Middle lobe, lingula and lower lobes.

Clinical pearls from this deck

• Transient tachypnoea is early and brief; ciliary distress is late, long and collapses a lobe.
• One faulty cilium, two problems: a wet chest and a heart on the wrong side.
• One affected child: test the brothers and sisters.
• Too young to close the palate: skip the nose test and go to the cilia.
• A low nose number narrows the field; it does not remove cystic fibrosis.
• Brush a recently infected nose and you may film the virus, not the gene.

Work through the deck once for recognition, then again a week later to test yourself — each question gives the answer and explains why every other option fails.
