Torsion of greater omentum is a rare cause of acute abdominal pain. It can be primary or secondary. Secondary omental torsions are associated with a number of preexisting conditions like inguinal hernia (most common), tumours, cysts, internal or external herniation, foci of intra-abdominal inflammation and postsurgical wound or scarring. Torsion of omentum causes twisting along its long axis resulting in impaired blood supply. This condition is rare and predominant in males. Most patients are middleaged adults. It clinically mimics acute appendicitis. If evaluated properly and diagnosed in time, good results can be achieved. We are presenting herewith a case of primary greater omental torsion and review of available literature.
Early diagnosis and treatment of tubercular meningitis (TBM) is one of the best predictors of survival. The smear testing of the cerebrospinal fluid (CSF) has a low sensitivity and cultures, though having higher sensitivity, take a long time in TBM diagnosis. The present study was done to evaluate the proportion of positive Gene Xpert test, a rapid nucleic acid amplification test, in clinically suspected patients with TBM. The results of Gene Xpert tests were then compared with the culture results. One hundred and fifty prospective patients with a clinical suspicion of TBM were classified as probable or possible TBM and underwent CSF examination for culture and Gene Xpert assay. Out of 124 patients available for statistical evaluation, 52 were in the probable and 72 in possible TBM group. The proportion of patients with Gene Xpert positivity were significantly more in probable compared to possible TBM (63.15% vs 36.85%, p<0.001). Twenty-eight patients had a positive culture result. The sensitivity of Gene Xpert relative to culture testing was 68.42%, specificity of 97.61%, a positive predictive value of 92.85% and a negative predictive value of 87.23%. Gene Xpert testing provided a rapid diagnosis in patients suspected with TBM. The high sensitivity and specificity of this test relative to culture testing is a strong indication that it should be included as one of the gold standard tests in patients with suspected TBM.
Recurrent and chronic rectal prolapse might lead to irreducibility and ultimately gangrene of the rectum if neglected. Gangrenous rectal prolapse is a surgical emergency and needs urgent surgical management. In view of irreducibility and gangrenous bowel, it is not advisable to attempt manual reduction of rectal prolapse. The only safe option that remains is perineal rectosigmoidectomy (Altemeier's operation). Here, we present our experience of five such cases operated in our institute from 2000 to 2015 with available literature review.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
