BackgroundDiagnosing intestinal (Luminal) tuberculosis is challenging due to limited yield of diagnostic modalities like CT scan, colonoscopy with blind ileal biopsies. GeneXpert MTB/RIF (Xpert) assays for diagnosing tuberculosis have been performed in the body secretions with excellent results. Its yield in stool is tested in this study.ObjectiveThe study aims to evaluate the yield of GeneXpert assay in stool of suspected cases of intestinal tuberculosis.MethodsHundred patients with suspected intestinal tuberculosis underwent routine biochemical tests, radiological investigations, colonoscopy with caecal and blind ileal biopsies for histopathology. Fresh stool samples were collected, processed for DNA extraction, tested using 2:1 ratio of GeneXpert reagent to sample to give positive or negative results for Mycobacterium tuberculosis and Rifampicin resistance.ResultsOut of hundred participants, 52% were female. Mean age was 28.21 ± 12.13. CT scan and colonoscopy findings suggestive of TB were present in 47% and 43% participants respectively. GeneXpert in stool was positive in 20% cases. Considering mucosal biopsy with histopathology of intestinal specimens as diagnostic of abdominal Tuberculosis, sensitivity and specificity of GeneXpert was 39.1% and 85.7% respectively.ConclusionStool GeneXpert assay offers an alternative approach to detect intestinal tuberculosis rapidly with good diagnostic accuracy. Although it cannot replace the AFB culture and histopathology but contribute for early diagnosis and management.
Behcet's disease (BD), also known as Behcet's syndrome, is a rare, chronic, autoimmune disorder of unknown origin. Its manifestations are thought to be caused by vasculitis, resulting in damage to blood vessels of all sizes throughout the body. We report a 25-year-old Pakistani male who is sexually active and presents with a one-year history of shortness of breath, cough, exertional dyspnea, and neck and facial swelling. On examination, he had severe anemia, mouth ulcers, distended neck and chest veins, prominent abdominal veins, and a scrotal ulcer. After going through mandatory investigations to evaluate the presenting signs and symptoms, thromboses were found in the major veins, including the superior vena cava (SVC) and external iliac vein, as well as a positive pathergy test. Accordingly, a diagnosis of Behcet's disease with cardiomyopathy and venous thrombosis was made. He was treated with anticoagulants, steroids, and azathioprine for six months and subsequently went into remission.
Study Design Systematic review and meta-analysis. Objective The clinical decision to pursue harmonic scalpel (HS) method vs conventional hemostasis to treat head and neck cancers has been arguably predicated on the clinical outcomes observed. This study aims to evaluate the surgical outcomes of neck dissection between both techniques and perform an updated meta-analysis using the available literature. Methods We searched PubMed, Scopus, and Cochrane Library through 31st December 2021, according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Outcome metrics included operative time and intraoperative blood loss. Secondary outcomes consisted of length of hospital stay, length of drain stay, total drain output, and postoperative complications. A meta-analysis was conducted using Review Manager Version 5.3 (RevMan) software employing the Random Effects Model. Results We identified 114 articles, out of which 10 randomized control trials (RCTs) analyzing a combined total of 558 patients met the inclusion criteria after title and full-text screening. Meta-analysis shows the group treated with HS had a significantly shorter operative time. [MD = −23.21, 95% CI (−34.30, −12.12) P value <.0001 I2 = 92%] but an insignificant lesser intraoperative blood loss [MD = −61.53, 95% CI (−88.61, −34.45) P < .00001 I2 = 79%]. Conclusions This study confirms that that HS use in neck dissection yields a reduced operative time and intra operative blood loss relative to conventional hemostasis. Furthermore, our paper shows no superiority of HS method over conventional hemostasis where length of hospital stays, length of drain stays, and postoperative complications are concerned. Future RCTs with high-level evidence may further elucidate the relative effectiveness of HS method over conventional hemostasis in treating head and neck cancers.
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.
