A retrospective study was done of the gastric pathology specimen results of 656 patients who underwent LSG at Amiri Hospital from 2008 to 2012.
Of the 656 patients, the average age was 33 years, and 480 (73.2 %) were female while 176 (26.8 %) were male. The histopathology results identified 488 (74.4 %) cases with chronic gastritis, 63 (9.6 %) with follicular gastritis, and 12 (1.8 %) with atrophic gastritis. A total of 12 (1.8 %) cases showed findings other than gastritis, including https://www.selleckchem.com/products/blu-285.html four (0.6 %) cases of gastric polyps, three (0.5 %) cases of granulomatous disease, and one (0.2 %) case each of the following: gastro-intestinal stromal tumor,
gastro-intestinal autonomic nerve tumor, intestinal metaplasia, collagenous gastritis,
and crypt cell apoptosis. Helicobacter pylori was discovered in 48 (7.3 %) of the patients.
The majority of gastric histopathology results after LSG in this study had an element of chronic gastritis (74.4 %), which is in keeping with previous studies showing its high prevalence among the obese population. However, a few cases had clinically significant pathologies, and this may alter post-operative management. In view of these results, Salubrinal nmr routine histological examination of the gastric specimens is highly recommended.”
“Objectives: Preoperative mapping of arterial and venous anatomy helps to prevent postoperative complications after vascular access creation. The use of gadolinium in contrast-enhanced (CE) magnetic resonance angiography (MRA) has been linked to nephrogenic
systemic fibrosis in patients with end-stage renal disease (ESRD). The purpose of this study was to evaluate non-contrast-enhanced (NCE) MRA for assessment of upper extremity and central vasculature and to compare it with CE-MRA.
Methods: NCE and CE-MRA images were acquired in 10 healthy volunteers and 15 patients with ESRD. In each data set, two observers analysed 11 arterial and 16 venous segments with regard to image quality (0-4), presence of artefacts (0-2) and vessel-to-background ratio.
Results: More arterial segments were depicted using CE-MRA compared to NCE-MRA (99% vs. 96%, p = 0.001) with mean image quality of 3.80 vs. 2.68, (p < 0.001) and mean vessel-to-background SN-38 ic50 ratio of 6.47 vs. 4.14 (p < 0.001). Ninety-one percent of the venous segments were portrayed using NCE-MRA vs. 80% using CE-MRA (p < 0.001). Mean image quality and vessel-to-background ratio were 2.41 vs. 2.21 (p = 0.140) and 5.13 vs. 3.88 (p < 0.001), respectively.
Conclusions: Although arterial image quality and vessel-to-background ratios were lower, NCE-MRA is considered a feasible alternative to CE-MRA in patients with ESRD who need imaging of the upper extremity and central vasculature prior to dialysis access creation.
