Patients with Parkinson disease often have orthostatic hypotension. Neurocirculatory abnormalities underlying orthostatic hypotension might reflect levodopa treatment. Sixty-six Parkinson disease patients (36 with orthostatic hypotension, 15 off and 21 on levodopa; 30 without orthostatic hypotension) had tests of reflexive cardiovagal gain (decrease in interbeat interval per unit decrease in sy...

INTRODUCTION I-gel is a relatively new supra-glotitc airway device which is claimed to be superior to laryngeal mask airway. It can be used ingeneral anesthesia with spontaneous ventilation as well as with positive pressure ventilation.This study was designed to assess whether I-gel creates adequate laryngeal seal during positive pressure ventilation in patients undergoing laparoscopic surgery....

The Valsalva maneuver was performed during cardiac catheterization in 9 patients who had undergone a Fontan operation (Fontan group) and in 10 control subjects. The Fontan group had higher right atrial (RA) pressure (16 f 1 vs 4 f 0.5 mm Hg, p <O.OOi), lower cardiac index (2.5 f 0.1 vs 3.7 f 0.2 liters/min/m*, p <0.05), lower stroke index (32 f 2 vs 44 f 2 ml/beat/m*, p <0.05), and higher syste...

PURPOSE Urodynamic studies are commonly performed as part of the preoperative work-up of patients undergoing surgery for stress urinary incontinence (SUI). We aimed to assess the extent to which these urodynamic parameters influence patient selection and postoperative outcomes. MATERIALS AND METHODS Patients presenting with SUI were randomly assigned to two groups: one undergoing office evalu...

PURPOSE Tape tension adjustment is an essential procedure in mid-urethral sling surgery. The goal of this study was to determine if intraoperative maximal urethral closing pressure (MUCP) elevation could be used as a reference value for adequate tape tension adjustment and predict transobturator (TOT) sling surgery outcome. MATERIALS AND METHODS A prospective study was performed using MUCP me...

Thirty-seven patients were evaluated before cardiac catheterisation by bedside physical examination, including Valsalva manoeuvre, to assess the value of the sphygmomanometrically determined arterial pressure responses during the Valsalva manoeuvre and to compare its sensitivity, specificity, and predictive accuracy in the detection of left ventricular dysfunction with that of the commonly used...

PURPOSE Recently, intrinsic sphincter deficiency (ISD) has been identified as one important factor in the outcome of stress urinary incontinence (SUI) related surgery. Clinical factors that can predict ISD are uncommon. The aim of this study was to determine predictive clinical factors for ISD in female patients with SUI. METHODS The patients were classified into 3 groups according to the val...

PURPOSE Detrusor overactivity (DO) cannot be predicted by clinical symptoms. Although it is possible that DO could be related to anatomical structures, scanty data exist about the relations between DO and anatomical structures. The aim of this study was to investigate anatomical differences in DO by measuring the thickness of the urethrovaginal space (UVS) and the urethral length (UL) in women ...
