PURPOSE To determine the association between ocular dominance and spherical or astigmatic anisometropia, age, and sex. METHODS Medical records of 10,264 myopic refractive surgery candidates were filtered. Ocular dominance was assessed with the hole-in-the-card test. Manifest refractive error was measured in each subject and correlated to ocular dominance.(More)
PURPOSE The aim of this study was to assess the tolerance dose of gastric mucosa for single-fraction computed tomography (CT)-guided, high-dose-rate (HDR) brachytherapy of liver malignancies. METHODS AND MATERIALS A total of 33 patients treated by CT-guided HDR brachytherapy of liver malignancies in segments II and/or III were included. Dose planning was(More)
Neuroendocrine tumors (NET) of the stomach are on the rise. In the United States they have increased about tenfold in the last 35 years. Prognosis has been much improved over the last three to four decades. Nowadays most of such NETs are diagnosed at an early stage. Quite often gastric NETs are found incidentally during a gastroscopy, performed for other(More)
Ein 23-jähriger Patient stellte sich mit schwerer, anbehandelter kontaktlinsenassoziierten Keratitis und Descemetozele vor. Nach 1 Woche intensiver antibiotischer Therapie wurde der Erreger Aspergillus fumigatus nachgewiesen. Trotz angepasster antimykotischer Therapie kam es zur kornealen Perforation. Um bei peripheren Randinfiltrationen auf eine(More)
The term "field cancerization" was coined by Slaughter in1953 when describing multifocal synchronous and metachronous carcinogenesis in the upper aerodigestive system. Patients suffering from head and neck cancer (HNC) have or develop a second esophageal squamous cell cancer (ESCC) or bronchial cancer (BC) in 5-14% of cases. When a second esophageal cancer(More)
A pseudoaneurysm of the hepatic artery is a rare complication of interventional endoscopy or transhepatic puncture. The present case report describes a symptomatic pseudoaneurysm of the left hepatic artery following endoscopic retrograde cholangio-pancreatography (ERCP). The indication was a biliary pancreatitis, and it was treated by(More)
PURPOSE This study was initiated to evaluate biomechanical changes using the Corvis ST tonometer (CST) on the cornea after laser in situ keratomileusis (LASIK). SETTING University Medical Center Hamburg-Eppendorf, Germany, and Care Vision Refractive Centers, Germany. DESIGN Retrospective cohort study. METHODS This retrospective study included 37 eyes(More)
PURPOSE To evaluate the effect of corneal cross-linking (CXL) in progressive keratoconus by applying in vivo static and dynamic Scheimpflug analyses. METHODS In this longitudinal retrospective study, corneal topography and tomography (Pentacam HD) and dynamic Scheimpflug-based biomechanical analyses (CorvisST [CST]) of 24 eyes of 24 patients with(More)
Two cases of delayed (36-month) Ancure hook fracture are reported in patients who experienced a decrease in aneurysm size and no evidence of endoleak. Both devices used redesigned hooks and are otherwise identical to those devices currently used in clinical practice. Notably, hook fractures were not visualized on all abdominal radiographic views, nor were(More)
The present study evaluated the clinical efficacy of a combined graft of autolysed antigen-extracted allogeneic (AAA) bone and microfibrillar collagen (Zyderm) covered with a resorbable collagen membrane in human infrabony defects. The results were compared at 1 year with debrided controls, AAA bone grafts alone, combined AAA bone-collagen grafts (without(More)
