What this deck covers

cystic fibrosis-related diabetes 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.

Diagnoses and management options tested

Across the 18 cases you are asked to choose between options such as: Autoimmune destruction of her beta cells, It becomes common from adolescence onwards, A fasting glucose the next morning only, Today, as one high reading is diagnostic, Check it often, giving insulin for persistent highs, Metformin, as it avoids injections, Cut her calories to lower the glucose, No treatment, as his fasting glucose is always normal, Rapid-acting insulin with meals, matched to food, Immediately, at the time of diagnosis, Her lungs are clearing the ketones, Untreated, it worsens his lungs and survival, No screening, as she had no diabetes before the transplant, Stop the insulin now, as he is cured.

Clinical pearls from this deck

CF diabetes: the scarred pancreas loses its islets.
CF diabetes arrives with adolescence, so screening starts at ten.
Night feeds in CF: check the glucose mid-feed and at the end.
A high glucose in a CF exacerbation: diagnose when well, not on the ward.
CF exacerbation on steroids with high glucose: monitor and give insulin.
CF diabetes: insulin, and only insulin.

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.
