To assess the influence of the body mass index (BMI) on the prevalence and severity of chronic daily headache (CDH) and its most frequent subtypes, transformed migraine (TM) and chronic tension-type headache (CTTH). ⋯ Chronic daily headache and obesity are associated. Obesity is a stronger risk factor for transformed migraine than for chronic tension-type headache.

Multicenter Study Comparative Study
Medication-overuse headache in patients with cluster headache.
Medication-overuse headache (MOH) in cluster headache (CH) patients is incompletely described, perhaps because of the relatively low prevalence of CH. ⋯ Medication-overuse headache is a previously underrecognized and treatable problem associated with cluster headache (CH). CH patients should be carefully monitored, especially those with a personal or family history of migraine.

Comparative Study
Neurologic prognosis and withdrawal of life support after resuscitation from cardiac arrest.
To study the impact of neurologic prognostication on the decision to withdraw life-sustaining therapies (LST) in comatose patients resuscitated after cardiac arrest. ⋯ In patients with poor neurologic recovery early after resuscitation from cardiac arrest, physicians appear to use the cortical evoked potential grade to estimate prognosis. Cortical evoked potential grade correlated with the waiting time until life sustaining therapies were withdrawn after no improvement in neurologic examination was seen.
