Valvular heart disease in patients with Parkinson's disease treated with pergolide, levodopa or both.

Cardiac valvulopathy has been reported in patients with Parkinson's disease treated with pergolide. The aim of this study was to clarify the frequency and severity of valvular heart disease (VHD) in patients treated with pergolide, levodopa or both. We evaluated VHD by transthoracic echocardiography in 25 patients who were taking pergolide, 29 patients taking levodopa and 20 patients taking both levodopa and pergolide.

Reduced P50 auditory sensory gating response in professional musicians.

Evoked potential studies have demonstrated that musicians have the ability to distinguish musical sounds preattentively and automatically at the temporal, spectral, and spatial levels in more detail. It is however not known whether there is a difference in the early processes of auditory data processing of musicians. The most emphasized and studied early process, especially for neuropsychiatric purposes, is sensory gating.

Cerebral artery hemodynamics in polycystic ovary syndrome.

Objective: The aim of the present study was to investigate hemodynamic changes in the medial cerebral artery and also the internal carotid artery in young women with polycystic ovary syndrome (PCOS) and polycystic ovaries (PCO).

Methods: Twenty-eight patients with PCOS, 16 patients with PCO and 24 healthy control subjects were included in the study. Blood flow rate, pulsatility index and back pressure of both the medial cerebral artery and the internal carotid artery were determined by transcranial Doppler ultrasonography and the results compared between groups.

Crocodile tears syndrome: botulinum toxin treatment under EMG guidance.

Crocodile tears syndrome is one of the rare complications of facial paralysis. There have been several reports of cases in which botulinum toxin was found to be useful in the treatment of crocodile tears syndrome. The adverse effects, due to the paralytic action of botulinum toxin, have been reported to involve the palpebral muscle, lateral rectus and superior rectus.

Sympathetic skin response in premenstrual syndrome.

Premenstrual syndrome is a term which includes a broad group of emotional, behavioral and physical symptoms that occur for several days before menses and subside following the menstrual period. Many women experience premenstrual syndrome symptoms, particularly physical ones such as breast tenderness and swelling. Approximately 5-10% women suffer from severe premenstrual syndrome and another 30-40% have moderate symptoms.

Cognitive event-related potential and neuropsychological findings in Behcet's disease without neurological manifestations.

Behcet's disease (BD) is a multisystem inflammatory disorder characterized by recurrent oral and genital ulcers and uveitis. BD patients without neurological involvement frequently have mild neurological symptoms. The aim of this study was to evaluate whether BD patients without neurological involvement have any changes in cognitive functions.

Isolated intracranial hypertension: a rare presentation of neurobrucellosis.

Brucella melitensis infection is endemic in the eastern and south-eastern Anatolia regions of Turkey. We report an unusual case of brucella meningitis presenting with bilateral papilla stasis, diplopia and absence of other neurological involvement. Diagnosis was made by positive culture of Brucella spp.

Topographic abnormalities in event-related potentials in children with monosymptomatic nocturnal enuresis.

Aims: A functional maturational delay in the central nervous system is dwelled upon in the pathogenesis of monosymptomatic nocturnal enuresis (MNE). In this study we studied whether according to controls N200 and P300, components of the event-related potential (ERP), which is related to aspects of cognitive processing, showed any difference in its topographic distribution in children within the age group 10-13 with monosymptomatic nocturnal enuresis and discussed its relation to the pathogenesis of MNE.

Methods: We performed P300 in 18 patients with MNE and in 16 age-matched healthy subjects.
