To assess programwide (outpatient plus inpatient) outcome using prospective measures for the first 6 months of treatment at a comprehensive headache center. Background.-There is little published data on the overall programwide efficacy of comprehensive, multidisciplinary treatment centers for severe, refractory headache disorders. ⋯ Despite a mean of only 3.50 medical visits in a population of complex patients, significant improvement was demonstrated in several key economically relevant variables within 6 months of referral. If maintained over the long term, the results support the concept that matching intensity of treatment (comprehensive/tertiary care) to severity of illness (complex/refractory cases) is cost-effective.

Hemicrania continua is a rare, benign headache disorder characterized by a low-level baseline hemicranial headache with superimposed exacerbations of more severe pain. Exacerbations last from minutes to days and may be associated with ipsilateral autonomic features such as ptosis, miosis, conjunctival injection, lacrimation, or rhinorrhea; when present, these features tend to be less pronounced than those seen with cluster headache. ⋯ To date, in the majority of instances, hemicrania continua appears to have arisen de novo, without any identifiable trigger. We report four patients in whom the onset of hemicrania continua was temporally linked to head trauma.

Cluster analysis was used to validate headache diagnostic criteria of the International Headache Society (IHS). Structured diagnostic interviews were conducted on 443 headache sufferers from a community sample, which was randomly split to allow replication. Hierarchical cluster analysis of symptoms in both subsamples revealed two distinct (P<.001) clusters: (1) unilateral pulsating pain, pain aggravated by activity, and photophobia and phonophobia, and (2) bilateral pressing/tightening pain, mild to moderate intensity, and absence of nausea/vomiting. ⋯ These results indicate that headache symptoms cluster empirically in a manner consistent with IHS criteria for migraine and tension-type headaches. Criterion overlap problems regarding pain intensity and duration were identified. Overall, these data support migraine and tension-type headache as distinct entities, and provide support for the IHS diagnostic criteria with minor modifications.

To evaluate autonomic function and sympathovagal balance in migraineurs and healthy controls. ⋯ Subjects with migraine with aura had resting supine sympathetic hypofunction and intact parasympathetic function. With head-up tilt, sympathovagal balance is increased. The dynamic alterations in autonomic nervous system function may contribute to the development of aura in patients with migraine.

A 64-year-old woman presented with bradycardia from sinus pauses during exacerbations of postherpetic trigeminal distribution neuralgia. She had underlying systemic lupus erythematosus. ⋯ The episodes of bradycardia resolved with successful alleviation of pain. This report emphasizes that a sphenopalatine ganglion blockade can be employed in the treatment and prevention of sinus arrest associated with postherpetic trigeminal distribution neuralgia.
