Welcome to The Pearl Log — where post-shift wisdom surfaces, one shiny clinical take at a time. Some pearls are fresh, some are rough, all are found under pressure.

Migraine Headache Pathophys + Diagnosis
Migraine is a primary disorder of neuronal dysfunction, driven by abnormal brain excitability and dysregulated pain modulation. Cortical spreading depression and trigeminovascular activation lead to CGRP-mediated neurogenic inflammation and progressive sensitization, leading to aura, headache pain, and associated symptoms. This modern framework clarifies why migraine presents in predictable phases and why early, mechanism-targeted treatment in the ED matters.
a BIG Deal.
The Brain Injury Guidelines provide an evidence-based framework to safely risk stratify patients with blunt traumatic brain injury and intracranial hemorrhage. By incorporating clinical context alongside imaging findings, mBIG helps reduce unnecessary neurosurgical consultations, repeat CT scans, and admissions. Implementation should remain institution-specific and grounded in clinical judgment and system capabilities.
A Case of Altered Speech
A patient presented with several days of unusual, deliberate speech changes without other focal neurologic deficits, prompting an unexpected finding on neuroimaging.
Potpourri: Recurrent Hypoglycemia, Valproic Acid Overdose, Vertigo, and Autism
A mixed bag of medicine and myth from this week’s shifts:
recurrent hypoglycemia (think meds, organ failure, and missed meals), valproic acid toxicity (with carnitine on your side), and a reminder to assess for the timing and triggers of vertigo. Oh—and Tylenol doesn’t cause autism. Read the studies, follow the money, and keep your critical lens sharper than your 10-blade.
