We show that the number of labeled cubic planar graphs on n vertices with n even is asymptotically αn −7/2 ρ −n n!, where ρ −1. = 3.13259 and α are analytic constants. We show also that the chromatic number of a random cubic planar graph that is chosen uniformly at random among all the labeled cubic planar graphs on n vertices is three with probability(More)
BACKGROUND Volar plating is commonly used in the management of distal radius fractures; bioresorbable plates have attractive features. We compared a bioresorbable plate with a latest generation and an established locked titanium plate. METHODS Twenty-four fresh-frozen radii (12 pairs) were assigned to three mean bone mineral density-matched groups of(More)
Postcataract extraction ptosis is a common complication of cataract surgery. While many factors have been implicated in its etiology, trauma to the superior rectus/levator complex is considered the most important factor. We prospectively evaluated the effect of two superior rectus bridling techniques on the degree and severity of ptosis present three months(More)
The purpose was to evaluate the feasibility of diagnosing vesicovaginal fistulas by colour Doppler ultrasound with contrast media. Twelve consecutive patients were examined by vaginoscopy, methylene blue test, cystogram and cystoscopy. For ultrasound examination, the bladder was filled with saline. Then diluted contrast media (Levovist) was instilled.(More)
OBJECTIVES To determine the outcome of patients with a serum prostate-specific antigen (PSA) level >20 ng/ml that underwent radical prostatectomy (RP). METHODS We retrospectively reviewed the medical records of 147 patients who underwent RP for clinically localized prostate cancer with a pre-treatment PSA (PSApt) >20 ng/ml. Fifty-two patients had positive(More)
AIM Standard diagnostic tools for vesico-intestinal fistulas are cystoscopy, cystography, colonoscopy, and contrast enema. The aim of our study was to evaluate the efficacy of transrectal 3D-ultrasound with contrast media in these patients. METHOD From 5/98 to 12/99 we examined 10 patients with symptoms of a vesico-intestinal fistula (pneumaturia,(More)
INTRODUCTION Treatment options for lymph node positive prostate cancer are limited. We retrospectively compared patients who underwent external radiotherapy (ERT) to patients treated by radical prostatectomy (RPX). MATERIALS AND METHODS A total of 102 lymph node positive patients from the RPX series at Ulm University were evaluated. In all, 76 patients(More)
Anisometropic and strabismic amblyopes were studied using the Regan Contrast Sensitivity Charts. At all levels of contrast, the amblyopic eyes of both the strabismic and anisometropic patients scored significantly lower than did their fellow normal eyes, which were used as controls. In comparing the differences between the normal and amblyopic eyes of both(More)
