PURPOSE To examine the proposed relation between gastroesophageal reflux disease and cancers of the larynx and pharynx. EXPERIMENTAL DESIGN A cohort of 66,965 patients with discharge diagnoses of heartburn, hiatal hernia, or esophagitis was identified in the Swedish Inpatient Register. We observed a total of 376,622 person-years in the cohort. Identification of laryngeal and pharyngeal cancer...

PURPOSE Recently, several studies have suggested that distal ureteral dilatation is an important factor influencing the spontaneous resolution of primary vesicoureteral reflux (VUR). We evaluated the relationship between distal ureteral dilatation and the spontaneous resolution of primary VUR. MATERIALS AND METHODS The medical records of 114 patients with primary VUR maintained on prophylacti...

AIMS To evaluate association between duodenogastric reflux and early gastric mucosal changes before and after the cholecystectomy procedure. MATERIALS AND METHODS Patients were evaluated with preoperative and postoperative endoscopy and endoscopic biopsy. Demographic and clinical characteristics, histological parameters, presence of duodenogastric reflux, and Updated Sydney scores were noted....

BACKGROUND/AIMS Obstructive sleep apnea is becoming more important in gastroesophageal reflux disease (GERD) patients. This study investigated the prevalence of high risk for obstructive sleep apnea in GERD patients in comparison with that in healthy controls using the Berlin Questionnaire. We also investigated the risk factors for obstructive sleep apnea in GERD patients. METHODS We enrolled...

BACKGROUND/AIMS This study was designed to investigate risk factors related to asymptomatic erosive esophagitis and the natural history of both endoscopic findings and reflux-related symptoms in subjects with asymptomatic erosive esophagitis. MATERIALS AND METHODS On a retrospective basis, data were gathered from patients with erosive esophagitis (Los Angeles classification 3A) who had underg...

OBJECTIVE This study aimed to evaluate the possible effects of Helicobacter pylori (H. pylori) infection in reflux esophagitis with scleroderma. PATIENTS AND METHODS There were a total of 138 patients with scleroderma in our hospital between October 1998 and June 2005. Among these patients, 64 consecutive patients of scleroderma, who did not receive medication for gastrointestinal diseases, u...

Pitch button blocking (PBB), involving attaching small pitch buttons between the back of a thin workpiece (i.e., optic) and a blocking plate, enables noncompliant convergent polishing in which the workpiece stiffness and block interface strength are maintained. This process has been optimized, and practical design criteria (number, size, and spacing of pitch buttons) have been determined both e...

Topology optimized architectures are designed and printed with programmable Poisson's ratios ranging from -0.8 to 0.8 over large deformations of 20% or more.

This paper mainly studied the inhibitory effect of total ethanol extract of Radix Sophorae Flavescentis on proliferation of colon cancer HT29 cells. By reflux extraction method and with ethanol as extraction solvent, different extracts were obtained at different ethanol concentrations, different solid-liquid ratios, and at different times. And their inhibitory activities against HT29 cells were...
