We have observed 27 migraineurs whose headaches occurred in groups separated by headache-free periods. Twenty-one of the patients were women. The headaches occurred on either side in most patients. The headaches were severe lasting for an average of 25.5 hours, often preceded by scintillating scotomas, and often associated with nausea, vomiting, and(More)
The syndrome of cluster headache variant is characterized by the occurrence of three combined symptoms: atypical cluster headaches, multiple jabs, and background vascular headaches. Atypical cluster headaches are localized headaches that occur several times daily, usually without any headache-free periods. They differ from the typical chronic cluster(More)
Three patients presented with sudden visual impairment followed by agitated delirium one to three days later. Examination revealed marked agitation, dementia, and loss of vision. Computerised axial tomography demonstrated temporo-occipital infarctions. All recovered from the agitated state in four days to two months, but their visual impairment and dementia(More)
BACKGROUND In HIV-infected patients, combination antiretroviral therapy (cART) is associated with clinical lipodystrophy (CL) and metabolic abnormalities (MA). This study aimed to evaluate the prevalence of the metabolic syndrome (MS) and its components, and to determine whether patients with or without CL had a different prevalence of MA. METHODS We(More)
We describe seven patients with vascular headaches. Five of them had cluster headaches, which were preceded by migrainous scotamata (two patients), weakness contralateral to the pain (one), accompanied by ipsilateral photopsias (one), or by contralateral paresthesias (one). The other two patients had "clusters" of daily common migraine headaches separated(More)
One year after a gunshot wound in the popliteal fossa, a 30-year-old man began to experience cramps and myokymia in the left gastrocnemius muscle. Myokymia was characterized by vermicular fibrillary movements localized to the gastrocnemius muscle and accompanied by plantarflexion and dorsiflexion of the toes. Neurologic examination, nerve conduction(More)
The endocrine system may be the target of different types of trauma with varied consequences. The present article discusses trauma of the hypothalamic-pituitary axes, adrenal glands, gonads, and pancreas. In addition to changes in circulating hormone levels due to direct injury to these structures, there may be an endocrine response in the context of the(More)
BACKGROUND Lipodystrophies are characterized by adipose tissue redistribution, insulin resistance (IR) and metabolic complications. Adipokines and hormones related to body composition may play an important role linking these alterations. Our aim was to evaluate adipocyte-derived hormones (adiponectin, leptin, resistin, TNF-α, PAI-1) and ghrelin plasma(More)
