Background: The human ATP-dependent SWItch/sucrose nonfermentable (SWI/SNF) complex functions as a primary chromatin remodeler during ontogeny, as well as in adult life. Several components of the complex have been suggested to function as important regulators of tumorigenesis in various cancers. In the current study, we have characterised a possible tumour suppressor role for the largest subunit of the complex, namely the AT-rich interaction domain 1B (ARID1B).

IntroductionAlthough surgery is the preferred treatment for grade III&IV pancreatic trauma, there is a growing movement for non-operative management. in blunt pancreatic trauma. Very few studies compare operative versus non-operative management in adult patients.MethodsRetrospective analysis of a prospectively maintained database was performed from 2004 to 2013 in the department of gastrointestinal surgery, NIMS, Hyderabad. Comparative analysis was performed between patients who failed versus those who were successfully managed with non-operative management.Results34 patients had grade III/IV trauma out of which 8 were operated early with the remaining 26 initially under a NOM strategy, 10 of them could be successfully managed without any operation. Post-traumatic pancreatitis, Necrotizing pancreatitis, Ileus, contusion on CT, surrounding organ injuries are independently associated with failure of NOM on a univariate analysis. On multivariate logistic regression presence of necrosis& associated organ injury are factors that predict failure of NOM independently. Development of a pseudocyst is the only significant factor that is associated with a success of NOM.ConclusionsNon-operative measures should be attempted in a select group of grade III&IV blunt pancreatic trauma. In hemodynamically stable patients with a controlled leak walled off as a pseudocyst without associated organ injuries and pancreatic necrosis, NOM has a higher success rate.

Highlights Heightened awareness and understanding of Obturator Hernias is important. Delays in diagnosis and treatment increase Morbidity and Mortality. Laparoscopic techniques of repair are met with increasing success in both elective and an emergency setting.

The survival rates of gastric cancer patients with cytology-positive peritoneal lavage fluid without macroscopic dissemination (CY+/P-) is the same as that of patients with overt peritoneal metastasis.The 5-year survival rate of such patients is only 2%. The current study aims to highlight its significance in the staging of gastrointestinal malignancies and its implications for patient care. Prospective nonrandom analysis of peritoneal wash cytology in patients with gastrointestinal malignancies was conducted in the department of Surgical Gastroenterology, Nizams Institute of Medical Sciences, Hyderabad from January 2012 to June 2013. Descriptive statistics and ANOVA variance analysis was performed to estimate incidence, risk factors and the effect of surgery in causing peritoneal dissemination of malignancy. A total of 60 patients with operable gastric cancer underwent peritoneal lavage for evaluation of malignant cells. The incidence of Positive peritoneal lavage cytology was 8.3% (5/60).Four patients with positive lavage fluid belong to T3 stage (11.7%, p-0.309).Poorly differentiating and mucinous tumors had a higher incidence of positive cytology (18.1% and 25%).None of the patients with positive cytology had positive resection margin. Tumors with advanced T stage, lymph nodal involvement, lympho-vascular and perineural invasion have higher incidence of positive peritoneal cytology. Surgical handling has a negligible effect in peritoneal dissemination of tumor. Large scale studies are warranted to validate the findings and define it's role in management of gastric cancer.
