Chromogenic chromID® CARBA medium was compared with CDC method and MacConkey agar with imipenem for its performance in detecting carbapenemase-producing Enterobacteriaceae (CPE) during a faecal screening surveillance program. Double rectal swabs were collected from patients hospitalized in the ICU. One swab was inoculated onto the solid media chromID® CARBA(More)
BACKGROUND The aim of the present study was to evaluate the recovery potential of the parotid glands after using either 3D-conformal-radiotherapy (3D-CRT) or intensity-modulated radiotherapy (IMRT) by sparing one single parotid gland. METHODS Between 06/2002 and 10/2008, 117 patients with head and neck cancer were included in this prospective,(More)
INTRODUCTION To identify potential risk factors for the development of jaw osteoradionecrosis (ORN) after 3D-conformal radiotherapy (3D-CRT) and intensity-modulated radiotherapy (IMRT) among patients with newly diagnosed head and neck cancer. MATERIAL AND METHODS This study included 776 patients who underwent 3D-CRT or IMRT for head and neck cancer at the(More)
PURPOSE To determine the influence of concomitant radiochemotherapy with cisplatin on parotid gland tissue complication probability. METHODS AND MATERIALS Patients treated with either radiotherapy (n = 61) or concomitant radiochemotherapy with cisplatin (n = 36) for head-and-neck cancer were prospectively evaluated. The dose and volume distributions of(More)
The aim was to improve the prediction rate of hyposalivation after using a modern 3D-conformal-radiotherapy-technique (3D-CRT) by sparing of the contralateral parotid gland. Between June 2002 and October 2006, 107 patients (90 male, 17 female, average age: 58 years) with squamous cell carcinoma of the head and neck were included in a prospective,(More)
The aim of the present study was to evaluate whether radiation damage on dental hard tissue depends on the mean irradiation dose the spared parotid gland is subjected to or on stimulated whole salivary flow rate. Between June 2002 and October 2008, 70 patients with neck and cancer curatively irradiated were included in this study. All patients underwent(More)
The aim of this study was to evaluate the clinical performance of fixed dental prostheses (FDPs) with computer-aided design (CAD)/computer-aided manufacturing (CAM)-fabricated titanium substructures veneered with low-fusing porcelain after 6 years. Thirty-one FDPs for 23 patients were fabricated. The frameworks were designed and milled using an early(More)
STATEMENT OF PROBLEM Computer-aided design/computer-aided manufacturing (CAD/CAM) titanium ceramic restorations were developed with the potential for replacing expensive, high noble metal ceramic restorations. However, little information exists about the clinical performance of CAD/CAM titanium ceramic single crowns. PURPOSE The purpose of this study was(More)
The accumulation of 5 alpha-dihydrotestosterone (DHT), particularly in stroma, is a possible etiological factor in regard of the age-dependent development of benign prostatic hyperplasia (BPH). In this context, we have recently demonstrated age-dependent alterations of 5 alpha-reductase, which is responsible for the irreversible conversion of testosterone(More)
