PURPOSE To determine effectiveness of Valsalva maneuver and standing position on scrotal color Doppler ultrasound (CDU) for the varicocele diagnosis. MATERIALS AND METHODS We reviewed the physical examination and CDU finding in 87 patients who visited National Police Hospital from January 2011 to April 2014. Diameters of pampiniform plexus were measured bilaterally during resting and Valsalva...

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...

To determine the possible relationship between left ventricular dilatation and heart rate changes provoked by the Valsalva maneuver (Valsalva ratio), we studied 9 patients with isolated chronic aortic insufficiency. Left ventricular systolic function was assessed by two-dimensional echocardiography and cardiac catheterization. All patients were asymptomatic (functional class I of the New York H...

The dose dependent responses to atropine of 11 indices of autonomic function were investigated in 10 healthy volunteers. Five subjects were given cumulative doses of atropine (0.1-2.0 mg/70 g, intravenously). The other five received equivalent volumes of water for injection. The ratio of the longest to the shortest R-R intervals in the electrocardiogram during forced expirations and deep inspir...

The purpose of this study was to investigate the influence of the Valsalva maneuver (VM) on cardiac hemodynamics in patients with patent foramen ovale (PFO). Sixty-five patients who were highly suspected to have PFO were included. The changes in E, A, E/A ratio of mitral valve blood flow, E, A, E/A ratio of tricuspid valve blood flow, left ventricular end-diastolic volume, area and right atrial...

PURPOSE To investigate lamina cribrosa (LC) displacement during the Valsalva maneuver in young healthy eyes using enhanced depth imaging (EDI) spectral-domain optical coherence tomography (SD-OCT). METHODS Forty-eight eyes of 48 young healthy volunteers (age range: 20-34 years) underwent intraocular pressure (IOP) measurement by Goldmann applanation tonometry as well as Cirrus HD-OCT scans be...

Background: Cervical spondylosis is a common progressive degenerative disorder of the human spine often caused by the natural aging process. Osteophytic formations contribute to biomechanical changes that result in neural and vascular compression. The spinal compression of the obliquely passing cervical nerve roots can result in possible autonomic imbalance in the body. Valsalva maneuver is a s...

BACKGROUND The Valsalva manoeuvre is an internationally recommended treatment for supraventricular tachycardia, but cardioversion is rare in practice (5-20%), necessitating the use of other treatments including adenosine, which patients often find unpleasant. We assessed whether a postural modification to the Valsalva manoeuvre could improve its effectiveness. METHODS We did a randomised cont...
