One hundred and thiry-four patients with hypertrophic cardiomyopathy were evaluated by standard 12-lead electrocardiography. Normal electrocardiograms were extremely uncommon, occurring in less than 7% of each subgroup of patients (i.e., those with or without either symptoms or obstruction to left ventricular outflow), with the exception of those who were both asymptomatic and had no left ventr...
PURPOSE Virtual colonoscopy is the most recently developed tool for detecting colorectal cancers and polyps, but its effectiveness is limited. In our study, we compared the result of preoperative virtual colonoscopy to result of preoperative and postoperative colonoscopy. We evaluated also the accuracy of preoperative virtual colonoscopy in patients who had obstructive colorectal cancer that di...

DESIGN Retrospective chart review. SETTING Tertiary referral center. PATIENT(S) Men with nonobstructive azoospermia and MA who underwent micro-TESE. INTERVENTION(S) Microdissection TESE.

BACKGROUND Although atrial fibrillation (AF) has been linked to underlying coronary artery disease (CAD), data supporting this association have been based on ECG and clinical history for the definition of CAD rather than direct visualization of atherosclerosis. METHODS AND RESULTS The prevalence of CAD among patients with paroxysmal or persistent AF and without history of CAD was evaluated us...
INTRODUCTION Urinary bladder diverticula are frequently resulting from obstructions. Our literature review did not reveal any cases of acquired urinary bladder diverticulum caused by long-term transurethral catheterization. CASE PRESENTATION We report a rare case of a nonobstructive big urinary bladder diverticulum developed after a long-term urethral catheterization in a 62-year old male dia...
Simultaneous intraventricular pressure gradients and ejection flow patterns were measured by a multisensor catheter in 6 patients with normal left ventricular function and no valve abnormalities, at rest and in exercise. Peak measured intraventricular pressure gradients were attained very early in ejection, amounted to 6.7 +/- 1.9 (SD) mm Hg at rest, and were intensified to 13.0 +/- 2.3 mm Hg d...
The clinical management of men with nonobstructive azoospermia (NOA) seeking fertility has been a challenge for andrologists, urologists, and reproductive medicine specialists alike. This review presents a personal perspective on the clinical management of NOA, including the lessons learned over 15 years dealing with this male infertility condition. A five-consecutive-step algorithm is proposed...
