Distal colon decompression had sensitivities and specificities of 91% (10 of 11 patients) and 83% (10 of 12 control subject), respectively, on topograms and of 91% (10 of 11 patients) and 92% (11 of 12 patients), respectively,
on CT images. On cross-sectional CT images, greater than 10-cm cecal distention, left upper quadrant cecal apex, whirl, ileocecal twist, transition point(s), X-marks-the-spot, and split wall had sensitivities of 45% (five of 11 patients), 36% (four of 11 patients), 73% (eight of 11 patients), 54% (six of 11 patients), 82% (nine of 11 patients), click here 27% (three of 11 patients), and 54% (six of 11 patients), respectively; each had 100% specificity. Pneumatosis intestinalis and free air had 100% (four of four control subjects) specificity. Overall, CT signs of bowel ischemia correlated poorly with pathology report findings.
Conclusion: When cecal volvulus is suspected, the absence of distal colonic BI 2536 cell line decompression on CT topograms makes the diagnosis very unlikely. Whirl, ileocecal twist, transition points, X-marks-the-spot, and split wall
have high specificity for cecal volvulus. (C) RSNA, 2010″
“Kayexalate (sodium polystyrene sulfonate) is a cation-exchange resin used to treat patients with hyperkalemia. Concomitant administration DAPT of kayexalate and sorbitol may induce gastrointestinal injury, which is potentially lethal. However, this well-documented complication is often underrecognized both clinically and pathologically. We propose a typical case along with colonoscopic photos and microscopic pictures. Additionally, we also present a review of the literature on this rare drug-induced side effect.”
“This article described the preparation of temperature-responsive chromatographic column containing poly(N-isopropylacrylamide) and poly quaternary
ammonium salt. Poly (N-isopropylacrylamide) and poly ([2-(methacryloyloxy)ethyl] trimetylammonium chloride) were synthesized and grafted to amino modified silica gel. The temperature responsive polymer grafted silica gel was characterized using Fourier transform infrared spectroscopy, thermoweight loss, and elemental analysis. The temperature responsive chromatographic column was used to analyze lactic acid and creatine phosphate disodium salt by controlling of the column temperature from 10 to 50 degrees C. The mixture of lactic acid and creatine phosphate disodium salt was baseline separated at pH 6.93. (C) 2011 Wiley Periodicals, Inc.
