Rapid eye movement dependent central apnea with periodic leg movements.

Central sleep apnea is a period of at least 10 s without airflow, during which no ventilatory effort is present. Most of the central apneas occur in Non-Rapid eye movement (NREM) sleep. Central apnea occuring in Rapid eye movement (REM) sleep is extremely rare.

The relationship of median nerve F-wave parameters with severity and subtypes of carpal tunnel syndrome.

Purpose: F-wave analysis may help affirm or disprove a compression neuropathy. In this study we have analysed the effects of focal median nerve injury on F wave in Carpal Tunnel Syndrome (CTS).

Method: We studied 57 patients (100 hands) with clinical and electrophysiological CTS and 31 (62 hands) healthy subjects.

Paraoxonase 1 gene polymorphisms, paraoxonase/arylesterase activities and oxidized low-density lipoprotein levels in patients with migraine.

The vascular endothelial dysfunction has been implicated in the pathogenesis of migraine. Oxidized low-density lipoprotein (ox-LDL) may impair endothelial function. Paraoxonase-1 (PON-1) prevents oxidative modification of LDL cholesterol (LDL-C).

Prognostic values of lesion volume and biochemical markers in ischemic and hemorrhagic stroke: a stereological and clinical study.

Purpose: Our aim was to evaluate the relationship between lesion volume, serum level of biochemical markers, and clinical situation in ischemic and hemorrhagic stroke.

Methods: MRI was obtained on 33 ischemic and 28 hemorrhagic strokes. The Cavalieri method was used to measure the volume.

Sensitivities of conventional and new electrophysiological techniques in carpal tunnel syndrome and their relationship to body mass index.

The purpose of this study is to evaluate prospectively the sensitivities of conventional and new electrophysiological techniques and to investigate their relationship with the body mass index (BMI) in a population of patients suspected of having carpal tunnel syndrome (CTS). In this study, 165 hands of 92 consecutive patients (81 female, 11 male) with clinical diagnosis of CTS were compared to reference population of 60 hands of 30 healthy subjects (26 female and 4 male). Extensive sensory and motor nerve conduction studies (NCSs) were performed in the diagnosis of subtle CTS patients.
