Developmental delay should be judged against thresholds, not reassurance alone. No words at 16 months or no sitting at 9 months warrants assessment, and early hand preference before 18 months can signal hemiplegic cerebral palsy rather than normal variation.

Eating disorders are missed when clinicians focus on weight alone. Parotid enlargement, dental erosion and Russell sign can indicate bulimia at normal weight, while more than five days of minimal intake should trigger refeeding-risk assessment before nutrition is restarted.

Social communication difficulty, language regression and rigid routines are the centre of this episode, which is the more focused paediatric listen today. It is most useful as a reminder to build the diagnosis from patterns across time and settings, not a single screening impression.

A reduced eGFR only becomes clinically useful when it is staged properly. This episode shows how urine albumin:creatinine ratio and chronicity turn abnormal bloods into chronic kidney disease risk, then links that stage to cardiovascular risk reduction, ACE inhibitor and SGLT2 choices, and referral thresholds.
