Headache

The main symptoms of acute primary angle-closure glaucoma (PACG) include pain in the head and/or the eyes in addition to the characteristic halo and blurred vision. When loss of vision is accompanied by such pain, PACG is usually suspected. However, no information has been available regarding painless acute angle-closure glaucoma. ⋯ The formation of microemboli derived from the heart or carotid artery and/or the occurrence of some hemodynamic abnormality due to arteriosclerosis is closely related to amaurosis fugax, and most cases are complicated by intracranial or extracranial arterial lesions. In the present case, we provisionally diagnosed transient amaurosis fugax which, however, was shown by additional ocular testing to be painless PACG. Herein we describe our diagnostic process and the outcome.

Randomized Controlled Trial Multicenter Study
Efficacy and tolerability of naratriptan for short-term prevention of menstrually related migraine: data from two randomized, double-blind, placebo-controlled studies.
In a pilot study, naratriptan was significantly more effective than placebo in preventing menstrually related migraine (MRM) when given as 1 mg twice daily for 5 days beginning 2 days before the predicted onset of MRM for up to 4 menstrual cycles. ⋯ Naratriptan 1 mg twice daily for 6 days per month is effective and well tolerated when used for short-term prevention of MRM. More patients receiving naratriptan than placebo were satisfied with treatment. The observed increase in posttreatment attacks needs further study.

To examine the headache characteristics of women with migraine and endometriosis (EM), and differences in the prevalence of comorbid conditions between female migraineurs with EM, without EM and nonheadache controls. ⋯ Prevalence of EM is higher in women with migraine than in nonheadache controls. Migraineurs with EM have more frequent and disabling headaches, and are more likely to have other comorbid conditions affecting mood and pain, compared to migraineurs without EM.

To determine if patients with new daily persistent headache (NDPH) have elevated levels of tumor necrosis factor alpha (TNF alpha) in the CSF. ⋯ An elevation of CSF TNF alpha levels was found in almost all NDPH patients and suggest a role for TNF alpha in the pathogenesis of this condition. Surprisingly, all CM and PT patients tested had elevated CSF TNF alpha levels. In most patients with elevated CSF levels, serum TNF alpha levels were normal. All of these syndromes may be manifestations of CNS inflammation. As most of the positive-tested patients showed minimal to no improvement during aggressive inpatient treatment, persistent elevation of CSF TNF alpha levels may be one of the causes of treatment refractory CDH.

To evaluate the structure and quality of sleep and the circadian rhythm of body core temperature (BcT degrees ) in patients with drug-resistant chronic cluster headache (CH) before and during deep brain stimulation (DBS) of the posterior hypothalamus. ⋯ Our data show that DBS of posterior hypothalamus in drug-resistant chronic CH is effective in curtailing nocturnal CH attacks, and is associated with improved sleep structure and quality. Chronic CH displays a normal circadian rhythm of BcT degrees, unchanged during hypothalamic DBS.
