Aortic dissection, febrile infants and headache treatment

May 30, 2026

Sudden maximal chest pain with syncope or neurological signs needs aortic CTA before anticoagulation escalates on an acute coronary syndrome pathway.

PEARL OF THE DAY

Sudden maximal chest pain plus syncope needs aortic imaging.

Summary

Sudden severe chest, back, flank or abdominal pain that is maximal at onset should keep aortic dissection active before anticoagulation, antiplatelets or thrombolysis escalate. Aortic dissection should come first because the bedside actions are immediate: ask about onset, tearing quality and migration, check bilateral pulses or blood pressures and neurological features, request dedicated aortic CTA of chest, abdomen and pelvis, and begin analgesia plus beta-blocker-based impulse control while surgical input is arranged.

The emergency medicine megamix adds risk-based documentation for febrile infants, bruising, anaphylaxis, ketamine-related urinary harm, asthma and diagnostic AI. Headache medicine adds personalised treatment history before triptan switching, while prion disease research reminds clinicians to separate mechanism, population and aspiration from proven benefit.

TSN 5 - The Aortic Dissection Dilemma with Dr. Kenny Chang

Severe sudden chest, back, flank or abdominal pain that is maximal at onset or migratory should interrupt an acute coronary syndrome pathway. Check pulses, blood pressures, neurological features and perfusion, then request dedicated aortic CTA rather than pulmonary embolism protocol imaging.

RCEM AC Interview Megamix May 2026

Emergency medicine reasoning across febrile infants, bruising, anaphylaxis, ketamine harm, diagnostic AI and asthma depends on using tools as support. The concrete habit is to document age, appearance, findings, assumptions and safety-netting before a pathway drives the decision.

Headache Medicine Highlights from the 2026 AAN Annual Meeting - Part 2

Recurrent headache reviews need a treatment history that names what worked, partly worked or failed. Triptan choice, preventive therapy and AI-supported recommendations should sit beside broad history, prior response and red or amber features rather than default prescribing habits.

Prion Disease Clinical Trial NN112

First-in-human prion disease research needs clear separation between symptomatic stabilisation and prevention in genetic-risk carriers. PRISM targets RNA encoding prion protein; the clinical point is to distinguish mechanism, population and aspiration from proven benefit.

What to change on your next shift

When severe chest, back, flank or abdominal pain is maximal at onset, pause before heparin, antiplatelets or thrombolysis. Ask about migration, syncope and neurological symptoms, check bilateral pulses or blood pressures, then arrange dedicated aortic CTA and impulse control when concern persists.

Questions from today’s episodes

Which pain pattern should bring aortic dissection forward?

Severe sudden chest, back, flank or abdominal pain that is maximal at onset, tearing or migratory should trigger concern. Chest pain with syncope, neurological signs, pulse deficit or abnormal perfusion strengthens the case for aortic imaging.

What imaging should be requested when dissection is suspected?

Request dedicated aortic CTA of chest, abdomen and pelvis. Pulmonary embolism protocol CTA, chest X-ray, POCUS, D-dimer or an unvalidated risk score should not be used as a standalone rule-out.

In a well febrile infant aged 29–60 days, what has to be in place before low-risk discharge?

Negative urine, low C-reactive protein and low neutrophil count may support discharge only with senior review and clear safety-netting. The age group, appearance and local pathway assumptions must fit the patient.
