Predicting migraine responsiveness to botulinum toxin type A injections.

Background: Botulinum toxin type A (BTX) is used prophylactically to reduce the frequency of migraine headaches, with inconsistent responses reported in the literature. The purpose of our study was to determine whether BTX injections at doses used for upper-face cosmetic purposes, which differ from doses typically used by headache specialists, could prevent imploding and ocular but not exploding migraines.

Observations: Study participants were recruited among patients who had received or were planning to receive BTX injections for upper-face cosmetic purposes but also reported having migraines.

Pancreatic panniculitis associated with acinic cell adenocarcinoma: a case report and review of the literature.
