Purpose: To examine the outcomes of vitreoretinal surgery for retinal disorders at Tilganga Eye Centre in kathmandu, Nepal. Design: Retrospective noncomparative case series. Participants: Records of 255 patients undergoing vitreoretinal surgery from December 2000 to January 2003 were reviewed. methods: Demographics, diagnoses, duration of symptoms, vision, and examination findings were noted before and after vitreoretinal surgery. main Outcome measures: Postoperative data were categorized by surgery type and analyzed by anatomic success, symptoms, and visual acuity (VA). Results: Sixteen percent of patients had >6/60 vision preoperatively, and the mean duration of vision loss before presentation was 4.9 months. major indications for surgery were retinal detachment (RD) (75% ) and vitreous hemorrhage (19% ). Anatomic success was achieved in 74.5% of patients. Postoperatively,39% of patients experienced improved VA, with 33% obtaining >6/60 vision. Conclusions: Despite prolonged duration of vision loss at presentation, vitreoretinal surgery in the developing world can restore useful vision in many patients with RD and vitreous hemorrhage.

The steep North to South (N-S) gradient and complex topography markssignificant variations in the spatial and temporal patterns of climatic variationsurrounding within a few distances in the Nepal Himalayas. Hence,to validate climatic linkages between the stations under two distinct topographicconditions, the study examines the observational climatic data from106m a.s.l. and 1801m a.s.l., as a representative station from a plain andhilly area. Different statistical tools including Pearson correlation analysisand a best-fit regression model were applied to analyze climate data. Theanalysis of 13129 daily average temperature records and 13147 daily totalprecipitation records showed that the variation in their sum and average ofdaily, five days, ten days, and monthly values between the stations in thedifferent elevations marked *** these variations, temperaturerecords are measured to be consistent in different altitudes and stronglycorrelated. The precipitation data showed a comparatively weaker *** coefficients (0.85-1.6) with R2>0.50 in the regression models forthe lower elevation and higher elevation station in the mid-mountain regionexcept for the monsoon season. It indicated a similar fluctuation of temperaturebetween these two stations in the respective area. The strong degreeof association and the change of climatic parameters in different rangeand elevations indicate the possibilities of using climatic data from Terai torepresent the mid-mountain region of central Nepal.

Endoscopic stent insertion into the gallbladder entails placement of a double-pigtail polyethylene stent between the gallbladder and the duodenum at ERCP. This proceduremay be an effective temporary measure in patients with severe comorbid conditions, especially end-stage liver disease, that subsequently allows more definitive therapy, including liver transplantation. The records for 29 patients who underwent attempted endoscopic gallbladder stent insertion between may 1999 and may 2004 were reviewed retrospectively. mean patient age was 47 years; 86%of the patients were listed for liver transplantation, with a mean model for end-stage liver disease score of 15; 72%had Child’s class B cirrhosis. Indications for gallbladder stent placement included recurrent biliary colic (69%), acute cholecystitis (17%), acalculous cholecystitis (7%), and gallstone pancreatitis (7%). Of the 29 patients who underwent ERCP, stent placement was successful in 26 (90%). median follow-up was 9.4 months (range 0.1-40.5 months). Of those who had a stent placed, 6 (22%) subsequently underwent liver transplantation and another 15 (56%) were alive, most awaiting liver transplantation. Only 3 patients had late a complication or recurrence of biliary symptoms after stent placement. Endoscopic stent placement in the gallbladder is a safe and an effective palliative treatment for patients with symptoms caused by gallbladder disease who are poor surgical candidates.
