Emergency clinicians and educators get a reflective, systems-focused discussion of teamwork, diagnostic uncertainty, technology and clinician wellbeing. Clear roles, shared mental models, patient advocacy and deliberate revision of the working diagnosis are presented alongside practical recognition of burnout, moral injury and post-traumatic stress.

Paediatric emergency and respiratory clinicians get an antibiotic-stewardship update for moderate to severe preschool wheeze. The episode links PRAM scoring, oxygenation, work of breathing, bronchodilator response and systemic corticosteroids with evidence that azithromycin does not improve symptom severity, length of stay or early return visits without a separate bacterial indication.

Emergency and critical-care teams get a focused appraisal of restricted fluids and early norepinephrine in adult septic shock. The ARISE Fluids findings are placed alongside fluid responsiveness, pulmonary oedema risk, peripheral vasopressor use and repeated bedside reassessment rather than automatic volume targets.

Paediatric emergency clinicians get a foreign-body ingestion risk-stratification episode. Small smooth blunt plastic objects in a well child usually pass spontaneously, while button batteries, multiple magnets, sharp objects, symptoms, uncertain high-risk history and deterioration require urgent escalation.

Acute-care and surgical teams get a practical framing for CT-confirmed uncomplicated appendicitis. It keeps antibiotics with observation tied to careful selection, appendicolith risk, surgical involvement, patient trade-offs, local antimicrobial guidance and written safety-netting for deterioration or recurrence.

Disaster medicine becomes less abstract when surge capacity, triage, evacuation and incident command are taught in plain language. Bite-sized learning helps clinicians and learners, with children and families kept visible in preparedness planning.

Selected stable adults with mild to moderate DKA may not need automatic intravenous insulin when a validated subcutaneous pathway and monitoring exist. The safety check is severity, mental state, haemodynamic status, pregnancy, comorbidity, potassium and local nursing capacity.

A dramatic paediatric wrist X-ray does not always predict long-term function. Choose this for children aged 4–10 years with displaced distal radius fractures, where neurovascular status, skin integrity, remodelling potential, surgical harms and family discussion shape cast-first care.

Coffee and tea data should reassure more than prescribe. Read this for the clean explanation of why observational associations do not prove dementia prevention, and for the sensible counselling line that tolerant moderate drinkers do not need to stop, but non-drinkers do not need to start.

Start here: a well-appearing febrile neonate still needs a disciplined first pass. Use urinalysis, absolute neutrophil count and procalcitonin to identify low-risk infants, then discuss selective lumbar puncture while keeping inpatient observation, culture results and clinical deterioration in view.
