ERCP practice at a tertiary care hospital in Kashmir, North India: a large single-center cross-sectional study with focus on quality indicators, success rate, and indications.

Endoscopic retrograde cholangiopancreatography (ERCP) is the most technically demanding endoscopic procedure with significant adverse events that mandate appropriate training, competence and careful decision-making. The American Society for Gastrointestinal Endoscopy (ASGE) and the European Society of Gastrointestinal Endoscopy (ESGE) updated a list of quality indicators and performance measures for pancreatobiliary endoscopy. Nevertheless, real-life data are scarce, especially from developing countries. The study aimed to assess overall quality, procedural success, and indications of ERCP at our center. Methods: An audit of our endoscopy center at the start of the study for quality and performance indicators and a retrospective analysis of the 4 years of the prospectively maintained data of patients who underwent ERCP regarding procedural success and indications was done. Results: The study showed that ERCP is performed by meeting good quality standards, but structured training, sedation practice, and microbiological surveillance are subpar. A total of 3544 procedures were carried out with successful cannulation of the naive papilla in 93%, with 60% of procedures carried out on females, 80.5% of procedures done for benign diseases, and 19.5% on suspected or proven malignancy (47% men and 53% women) with perihilar obstruction being commonest in both sexes (32-33%) followed by carcinoma gallbladder in women (21%) and distal cholangiocarcinoma in men (27%). Among benign diseases (2711), 12% had benign pancreatic diseases, and 64.8% had common bile duct (CBD) stones, with 31% of CBD stones requiring more than one session for clearance. Conclusion: ERCP at our center is performed by meeting quality standards and by competent endoscopists with good procedural success. Improving sedation strategies, microbiological surveillance, and training programs remains an unmet need.

Predictors of Rebleeding in Non-variceal Upper Gastrointestinal Bleeding of Peptic Ulcer Etiology in Kashmiri Population.

Background Upper gastrointestinal bleeding (UGIB) represents a substantial clinical and economic burden and rebleeding is one of the most important predictors of morbidity and mortality. Identifying patients who are likely to rebleed is a critical component of effectively managing patients with bleeding peptic ulcers. So, the study was undertaken to look for predictors of rebleeding in patients with bleeding peptic ulcers and try to find out the new scoring system to predict rebleeding in our population. Material and methods A retrospective analysis of prospectively maintained hospital data of UGIB patients was done and 480 patients of endoscopically documented peptic ulcers whose complete data was available were taken for study. Results Among the studied patients, men constituted 84.6%, and most of the patients were in the third to sixth decade of life with a mean age of 40.9±15.9 years, 76% were from rural areas. Only males with a mean age of 38.4±19.8 rebled with a rebleeding rate of 2.9% only. Half of the patients who rebled were in shock at the time of presentation. Those who rebled received more units of blood transfusion (mean 3±1.8), had a large mean ulcer size of Forest class IIa and IIb and epinephrine injection monotherapy group with varied statistical significance. Among rebleeders (n=14), eight patients were managed by a second endoscopic therapy, and six (42.8%) rebleeders and 1.25% of patients in total needed surgery. Two patients ultimately died giving overall mortality of 0.4% and mortality of 14.3% among rebleeders. Conclusion Our study found a very low rebleeding rate and mortality which could be explained by a young population with fewer co-morbidities and better response to proton pump inhibitor therapy. The significant parameters related to rebleeding were shock at presentation, degree of smoking, units of blood transfused, ulcer size, and high-risk endoscopic stigmata.

Occult hepatitis B virus infection as a cause of posttransfusion hepatitis in patients with cancers.

BACKGROUND: Prevalence of hepatitis B virus (HBV) infection is increased in patients of cancer with increased mortality. Multiple transfusions of blood and blood-related products are a potential source. AIMS: This study aims to assess the incidence of hepatitis B surface antigen (HBsAg) seroconversion in cancer patients receiving transfusion of blood or blood-related products and identify possible reasons for infection in these patients. MATERIAL AND METHODS: Patients of cancer receiving blood products, who were HBsAg-, anti-hepatitis B core (HBc)-, and HBV DNA-negative prior to transfusion, were tested for HBsAg by ELISA at 6, 12, and 24 weeks after the last transfusion. Blood donors were screened for HBsAg by ELISA. RESULTS: Twenty of 3,600 (0.56 %) blood donors tested positive for HBsAg and were rejected. Nine of 150 (6 %) cancer patients became HBsAg-positive posttransfusion which included seven patients who presented with acute hepatitis B and other two patients who remained HBsAg-positive without hepatitis. In 6/9 (66.6 %) patients, HBsAg positivity was related to blood transfusion as their corresponding blood donors on retesting the stored samples were positive for anti-HBc antibody and HBV DNA. In other three patients, the cause of their HBsAg positivity could not be ascertained. CONCLUSION: Occult HBV infection in blood donors is a potential source of posttransfusion HBV infection in recipients. Anti-HBc antibody and HBV DNA should be tested in blood donors especially when blood is given to cancer patients receiving chemotherapy.

Perioperative complications of intraocular lens exchange in patients with opacified Aqua-Sense lenses.

PURPOSE: To evaluate the perioperative complications of intraocular lens (IOL) exchange in 25 eyes of 22 patients with opacified Aqua-Sense IOLs (Ophthalmic Innovations International). SETTING: Department of Ophthalmology, University Hospital Aintree, Liverpool, United Kingdom. METHODS: The study comprised 22 patients (25 eyes) who had previous phacoemulsification and implantation of Aqua-Sense single-piece hydrophilic acrylic IOLs in the capsular bag and developed severe late opacification of the IOL. All patients reported glare and deterioration in vision. The IOLs were explanted and replaced with new lenses. The perioperative complications were evaluated. The best corrected visual acuity (BCVA) before and after surgery was compared. RESULTS: In 24 eyes, the opacification was complete, involving the optic, haptics, and substance of the IOLs. Uneventful IOL exchange and placement of a new IOL in the bag was achieved in 13 eyes (52%). Complications occurred in the remaining 12 eyes (48%). Ten eyes (40%) developed zonular dehiscence, 4 (16%) of which were managed with anterior chamber IOL implantation. One eye (4%) developed posterior capsule rupture and 1 eye (4%), posterior capsule rupture and zonular dehiscence. The cornea decompensated in 2 eyes (8%). One eye (4%) developed Pseudomonas keratitis. The mean BCVA (decimal scale) before and after IOL exchange was 0.57 +/- 0.24 and 0.60 +/- 0.28, respectively. There was no significant difference in visual acuity between before and after IOL exchange (P=.782, paired t test). CONCLUSIONS: Explantation of Aqua-Sense IOLs was challenging because of the tight adherence of the optic and haptics to the capsule. Long-term follow-up of patients with Aqua-Sense IOLs should be maintained.

In vitro Inhibition of HHV-6 replication by sophocarpines.

The virostatic activity of sophocarpines and gancyclovir (GCV) was tested using HHV-6 Z29 strain and Molt-3 cells. The cytotoxic (IC(50)) and the antiviral (ED(50)) values were first experimentally determined and selective indices (SI) were then calculated. The SI values for sophocarpines 1 and 2 and GCV were in the order 184, 183, and 23, respectively. Though preliminary, these findings indicate that sophocarpines have the potential to inhibit HHV-6 replication.
