This study aims to determine why patients with migraine present to an emergency department (ED). While migraine accounts for over 800,000 ED visits annually, no prospectively gathered data characterize patients' reasons for presenting to an ED. ⋯ Most migraineurs presenting to the ED have a PCP and health insurance. ED visits commonly result from an inability to access care elsewhere and because patients consider pain to be an emergency condition. Missed opportunities for diagnosis and treatment likely contribute to ED visits.

To prospectively describe the clinical characteristics of classical trigeminal neuralgia (TN) in a standardized manner. ⋯ This, the first study in a series of papers focusing on the clinical, radiological, and etiological aspects of TN, revealed that the symptomatology of TN includes a high percentage of concomitant persistent pain, autonomic symptoms, and sensory abnormalities. These findings offer new insights to the prevailing clinical impression of the clinical characteristics in TN.

Prevalence of primary headaches in an urban slum in Enugu South East Nigeria: a door-to-door survey.
This study aims to determine the prevalence of primary headache disorders using the second edition of international classification of headache disorders among urban slum dwellers. Headache is a common neurological disorder and one of the most common reasons for visiting the neurology clinics in Nigeria. Low socioeconomic status has been linked with primary headaches. Factors that may precipitate and sustain headaches are common in Africa especially in urban slums. There are limited population based data on the prevalence of headache from Nigeria and other African countries. ⋯ Headache is a common health problem in an urban slum in Enugu south east Nigeria where 66.7% of participants had experienced headache in their lifetime, and 49.4% had experienced primary headaches. The prevalence of migraine and TTH were 6.4% (5% in males and 7.5% in females) and 13.8% (12.2% in males and 15.1% in females), respectively. The peak ages of migraine and tension-type headache were 30-39 and 60-69 years, respectively. The prevalence of primary headaches was significantly higher among subjects who used alcohol significantly.

To determine whether the utilization of healthcare resources is reduced after chronic migraine patients are treated for 6 months with onabotulinumtoxinA. ⋯ Although we are unable to distinguish onabotulinumtoxinA's treatment effect from other potential confounding variables, our analysis showed that severely afflicted, treatment-refractory patients with chronic migraine experienced a significant cost-offset through reduced migraine-related emergency department visits, urgent care visits, and hospitalizations in the 6 months following treatment initiation of onabotulinumtoxinA. Future analyses will assess the longer-term effect of onabotulinumtoxinA treatment and the potential contribution of regression to the mean.

Occipital nerve blocks are commonly performed to treat a variety of headache syndromes and are generally believed to be safe and well tolerated. We report the case of an otherwise healthy 24-year-old woman with left side-locked occipital, parietal, and temporal pain who was diagnosed with probable occipital neuralgia. She developed complete left facial nerve palsy within minutes of blockade of the left greater and lesser occipital nerves with a solution of bupivicaine and triamcinolone. ⋯ Unintended spread of the anesthetic solution along tissue planes seems the most likely explanation for this adverse event. An aberrant course of the facial nerve or connections between the facial and occipital nerves also might have played a role, along with the patient's prone position and the use of a relatively large injection volume of a potent anesthetic. Clinicians should be aware that temporary facial nerve palsy is a possible complication of occipital nerve block.
