BACKGROUND Rectal cancer patients have a higher incidence of pulmonary metastases than those with colon cancer. This study aimed to examine the effects of rectal cancer level on recurrence patterns in rectal cancer patients. METHODS Patients with T3/T4 rectal cancers who underwent surgery between 2002 and 2006 were recruited in this study. All the patients were followed up on until death. Rec...

BACKGROUND Faecal impaction is frequently observed in children with chronic constipation. The term megarectum is often used to describe this finding. AIM To evaluate rectal functioning and rectal measures in constipated children with a filled rectum, in order to define the terms faecal impaction, enlarged rectum, and megarectum. METHODS All children underwent radiological investigation, col...

Adjacent parallel hot-wire anemometers at different temperatures have sometimes been used to measure fluctuating temperatures in turbulent flows. This work presents an extensive experimental comparison of temperatures measured with a parallel-wire probe to temperatures simultaneously measured with a standard cold-wire probe. The results show the parallel-wire probe to work well in low intensity...

2. Working Equations of the Vibrating-Wire Instrument Our implementation [1] of the steady-state vibrating-wire technique is similar to that described by Audonnet and Pádua [2] in which the wire is driven at frequency f by a constant sinusoidal current I, and the emf V(f) generated across the vibrating wire is measured with a two-phase lock-in amplifier. This measured emf generally comprises tw...

Temperature was measured in the left ventricle, aorta, liver, brain, lung, bone marrow, kidney, and spontaneous solid tumors in dogs undergoing whole body hyperthermia in a radiant heat device. Rectal temperature was found to be a satisfactory indicator of systemic arterial temperature during plateau temperature conditions but rectal temperature underestimated arterial temperature during heatin...

Background: The aim of this study was to investigate the association between plasma levels of homocysteine and the occurrence and progression of rectal cancer. Material/Methods: The 320 study participants included healthy controls (n=80). and patients with rectal tumors (n=240), including 155 patients with rectal cancer, Stage I (n=32), Stage II (n=38), Stage III (n=50), and Stage IV (n=35), an...

background and objectives: the etiology, pathophysiology, nomenclature and clinical manifes-tation of solitary rectal ulcer syndrome (srus) is poorly understood. aim: to examine the pathology of mucosal changes and clinical features of this syndrome. materials and methods: the mucosal biopsies of 19 patients with clinical evidence of solitary rectal ulcer as been reviewed in accordance with the...

background the sitting position, rather than squatting, during defecation has been hypothesized to be a risk factor for colorectal cancer (crc). methods we conducted a case-control study to test this hypothesis. a total of 100 crc cases from two hospitals in iran and 100 control subjects, selected from the coronary care unit (ccu) of those same hospitals were selected for this study. we adminis...

Background and aims: To elucidate the dynamics of nitric oxide (NO) production induced by rectal gluten challenge and the relation between NO production and mucosal granulocyte activation. Subjects and methods: Release of rectal NO was measured in 13 patients with coeliac disease and in 18 controls before and after rectal wheat gluten challenge. Rectal gas was collected with a rectal balloon us...
