Decreased cerebral vasomotor reactivity in patients with obstructive sleep apnea syndrome.

Objective: In obstructive sleep apnea syndrome (OSAS), any of the activated neural, vascular, hemodynamic, metabolic, inflammatory, and thrombotic mechanisms may be related to increased cerebrovascular disease and risk of death; however, the possible pathophysiological process between obstructive sleep apnea syndrome and stroke has not been clearly explained. We hypothesize that alterations in vasomotor reactivity in patients may be responsible for their altered cerebral blood flow, and may contribute to the increased risk of ischemic stroke.

Methods: A total of 30 untreated patients with severe obstructive sleep apnea and 26 control subjects were included in the study.

Association of nerve conduction impairment and insulin resistance in children with obesity.

Aim: The objective of our study was to investigate nerve conduction in normoglycemic obese children.

Methods: A total of 60 children with obesity (30 female and 30 male) and 30 healthy children (15 female and 15 male) were enrolled in the study. Insulin resistance (IR) and other metabolic disturbances were investigated and nerve conduction was measured in all participants.

Is overactive bladder a nervous or bladder disorder? Autonomic imaging in patients with overactive bladder via dynamic pupillometry.

Purpose: To evaluate the changes in dynamic pupillometry in patients with idiopathic overactive bladder (OAB).

Methods: The study included 40 female patients with idiopathic OAB and 40 healthy female volunteers as a control group. Demographic and clinical data were recorded.
