Hemorrhoidal disease affects more than one million Americans per year. We reviewed the treatment pattern for patients who presented with symptomatic hemorrhoids to our large university-affiliated group practice over a 66-month period. Over 21,000 patients presented to the practice with bleeding, thrombosis, or prolapse. Only 9.3 percent of patients required(More)
OBJECTIVE To present a pathology not previously informed in national literature. BACKGROUND Colitis cystica profunda (CCP) is a rare benign entity and with an unknown etiology. There are 148 cases documented in world literature at the present time. Histologically it is defined as the obliteration of lamina propria by fibroblasts and the presence of(More)
IPAA surgery has evolved to assume a major role in the operative management of CUC and FAP. In experienced centres, the safety of performing this somewhat complex procedure, often in gravely ill patients, has been confirmed. A significant decrease in morbidity has accompanied increased experience and simplification of the operative techniques. Two major(More)
Arterial blood gases are critical in regulation of cerebral blood flow (CBF) and cerebral metabolic rate for O(2) (CMRO(2)). However, the relation of these variables to cortical tissue (t ), and electrocorticographic (ECoG) activity (high voltage low frequency, HVLF, versus low voltage high frequency, LVHF), are not well defined. In the fetus, we tested the(More)
Communication within recreational computer-mediated settings has received less attention than interaction in instrumental and organizational contexts. The present study compared the socioemotional and task-oriented content of 5,826 text messages produced by participants of an online video game. The results suggest that participants produced significantly(More)
BACKGROUND Almost all colorectal cancers develop from adenomatous polyp, its detection and resection prevent the malignization. Several adenoma characteristics like: number, size, morphology, histologic type and grade of dysplasia have become considered as malignization risk factors. AIMS This study was designed to determine the frequency of colorectal(More)
OBJECTIVE We tested the hypothesis that supplemental CO2 can enhance the effect of maternal oxygen administration on fetal cerebral oxygenation. STUDY DESIGN In near-term fetal sheep (n = 6), we instrumented the cerebral cortex with tissue PO2-laser Doppler flow probes, and placed arterial catheters. Following a 30-minute control period, the ewe breathed(More)
