background: central obesity and hyperinsulinaemia of polycystic ovary syndrome (pcos) are associated with chronic sympathetic over activity. objective: to evaluate the autonomic functions and to indicate the superiority, if any, for those functions in the diagnosis of sympathetic over activity in pcos women. materials and methods: sixty-four pcos patients and 40 women served as the control grou...

Knowledge of the physiology underlying the autonomic nervous system is pivotal for understanding autonomic dysfunction in clinical practice. Autonomic dysfunction may result from primary modifications of the autonomic nervous system or be secondary to a wide range of diseases that cause severe morbidity and mortality. Together with a detailed history and physical examination, laboratory assessm...

Results In the present study, 16% of HIV +ve with the AIDS had abnormal autonomic dysfunction and 4% of HIV positive without AIDS had abnormal autonomic dysfunction. Reduced heart rate variability is the commonest manifestation of autonomic dysfunction noted in both HIV positive without AIDS and HIV positive with AIDS groups. Diastolic BP response to sustained handgrip has a limited role in dis...

one of the important complications of diabetes mellitus that physicians pay less attention to is diabetic autonomic neuropathy(DNA) ,especially cardiac autonomic neuropathy (CAN).this has a poor prognosis and is accompanied by sudden death risk,recently several investigations that were carried out for CAN detection ,suggested that QT-interval prolongation in these patients is an important diagn...

 Abstract Background: Dysfunction of the autonomic nervous system has long been a subject of considerable debate and a large number of studies have disclosed contradictory results. The aim of this study was to compare cerebral vasomotor reactivity in migraine with aura (MWA) patients with migraine without aura (MWO) ones. Methods: Ten MWA patients (7 females and 3 males mean age: 39.70 years, S...

Study of autonomic nervous system activity in chronic liver disease has aroused great interests due to its increasing prevalence due to various etiologies. The present study was undertaken to assess the autonomic nervous system activity in chronic liver disease patients by five standard autonomic function tests. Forty patients (20 with alcoholic liver disease and 20 with nonalcoholic liver dise...

BACKGROUND AND PURPOSE The potential association between the severity of autonomic dysfunction and peripheral neuropathy has not been extensively investigated, with the few studies yielding inconsistent results. We evaluated the relationship between autonomic dysfunction and peripheral neuropathy in chronic hemodialysis patients in a cross-sectional study. METHODS Cardiovascular autonomic fun...

BACKGROUND It was formerly believed that since fibrocalculous pancreatic diabetes (FCPD) is a secondary form of diabetes, specific diabetic complications were uncommon. This is no longer considered to be true. Our objective was to study the prevalence and pattern of cardiac autonomic neuropathy (CAN) in patients with FCPD. MATERIALS AND METHODS A cross-sectional study on consecutive male pati...
