[Evaluation of platelet serotonin levels in migraine without aura].

Objectives: The relation between migraine and serotonin levels is not clear. Plasma serotonin levels in migraineurs were investigated in previous studies. However, in the current literature, it is stated that measurement of serotonin level in platelets is more reliable.

Attenuated lactate response to ischemic exercise in migraine.

Background: Although the pathogenesis of migraine still remains unclear, certain metabolic studies done on patients with migraine indicate possible deficits in mitochondrial activity. Previously, the forearm ischemic exercise test (FIT) has been used as a screening tool to evaluate mitochondrial dysfunction in metabolic myopathies.

Material/methods: We studied the response of migraine patients to exercise using the modified FIT and compared this to the responses in a healthy group.

Determination of nerve conduction abnormalities in patients with impaired glucose tolerance.

Recent studies have shown that impaired glucose tolerance (IGT) is associated with dysfunction in the peripheral and autonomic nerves. The aim of this study was to determine the electrophysiological abnormalities of IGT. To determine electrophysiological abnormality in the large sensorimotor and sudomotor autonomic nerves with IGT patients, 43 patients and 34 healthy subjects have been studied.

Cutaneous drug eruptions by current antiepileptics: case reports and alternative treatment options.

Serious cutaneous drug eruptions due to antiepileptics have been defined for many drugs like carbamazepine, diphenylhydantoin, phenytoin and valproate. In recent years, adverse cutaneous reactions due to the current antiepileptic drugs have also been reported. In this paper, two cases are presented: a 48-year-old female receiving gabapentin for postherpetic neuralgia who developed leukocytoclastic vasculitis after 8 weeks and a 23-year-old male receiving lamotrigine for epileptic seizures who developed toxic epidermal necrolysis (TEN) in 15 days.
