Cluster headache is almost always idiopathic, but, in rare cases, associated intracranial lesions have been found. We describe a patient who had chronic cluster headache for more than 20 years. The headache immediately resolved upon resection of a tentorial meningioma. Prior reports of cluster headache as a manifestation of structural disease are briefly(More)
Four patients with typical anterior ischemic optic neuropathy experienced progressive deterioration of visual function, to acuity levels of finger-counting in two eyes, 20/400 in one, and 20/50 in the fourth. All subsequently enjoyed significant spontaneous recovery of vision to 20/60, 20/60, 20/40, and 20/25, respectively. No previous reports have(More)
We used [18F]fluorodeoxyglucose with positron emission tomography to explore the functional basis of lid opening apraxia (LOA). We studied four patients with LOA without associated pyramidal or extrapyramidal motor dysfunction (mean age 65.5 +/- 4.7 years). We compared measures of glucose metabolism with those calculated for 10 age-matched normal volunteers(More)
Lyme disease is a multisystem disorder caused by infection with the Borrelia burgdorferi spirochete. The diagnosis of Lyme disease usually is based on several clinical criteria, with supportive data from laboratory testing. The presence of the bullseye skin lesion, erythema migrans, is the single pathognomonic criterion. In the 20 years since the initial(More)
The proportions and some of the properties of X and Y cells in lateral geniculate nucleus (LGN) of adult cats were measured 14-16 days after monocular paralysis. The paralysis was produced by sectioning cranial nerves III, IV and VI. No difference from normal was observed in the proportions of X and Y cells either in the A layer driven by the paralyzed eye(More)
After radial keratotomy (RK) to correct myopia, some patients complain of 'glare'. Effects of a glare source on contrast sensitivity were measured in fifteen patients after unilateral RK. With each eye, determinations were made of the contrast required for detection of steady gratings (spatial frequencies of 0.7 and 2.9 cycles/deg), and for detection of(More)
The diagnosis of myasthenia gravis is usually confirmed by a Tensilon test, which can be complicated by cholinergic side effects that include cardiopulmonary arrest. An alternative, the Sleep test, based on the characteristic of myasthenia that symptoms and signs worsen with fatigue and improve after a period of rest, is safe, moderately sensitive, and(More)
Six patients (11 eyes) with virologically confirmed cytomegalovirus (CMV) retinitis involving the posterior pole of the eye were treated with a new drug, ganciclovir. Treatment with intravenous ganciclovir consistently halted progression of retinitis and produced improvement in measures of visual function. However, within three weeks after cessation of(More)
A 79-year-old man with myelodysplastic syndrome developed a right optic neuropathy with optic disc edema and intractable periocular pain, one month after undergoing removal of a gangrenous gallbladder. Although results of a temporal artery biopsy were negative, he was treated with prednisone for presumed temporal arteritis. Attempts at tapering the(More)
