Management outcome of residual common bile duct stones at Aga Khan University Hospital

Background: The frequency of residual common bile duct (CBD) stones in patients with previous cholecystectomy ranges from 2-10%, and a minimally invasive approach is generally recommended for these patients. This study reviews the experience in the management of residual CBD stones at the Aga Khan University Hospital.Methods: All adult patients diagnosed to have residual CBD stones, from 1993 to 2001, were identified and analyzed in terms of the treatment modality utilized and its associated complications. The role of endoscopic sphincterotomy was particularly analyzed in our set-up.Results: The study population consisted of 66 patients. The mean age was 52 (range:18-84 years) years with a female to male ratio of 51:15. The primary mode of management consisted of endoscopic sphincterotomy in 61 patients (92.5%). The initial clearance rate for these patients was 75%, while the remaining 25% required ancillary procedures to achieve a complete clearance. Procedure related complications were observed in 17 (28%) patients, with zero mortality. The other 5 patients (7.5%) underwent an open choledochotomy as a primary procedure with no further complications.CONCLUSIONS: Endoscopic sphincterotomy is the most frequent treatment modality used for the management of residual CBD stones at our hospital. Although initial success rate seems low, the fact that endoscopic sphincterotomy is a less invasive procedure justifies its preferential utilization. The study does not compare the results of endoscopic management with open surgery, as the number of patients managed by open choledochotomy is very small

On some properties of ideal convergent double sequences in fuzzy normed spaces

Recently, Rashid et al. [Rashid, Mohammad HM and Kočinac, Ljubiša DR. Ideal convergence in 2–fuzzy 2–normed spaces, Hacettepe Journal of Mathematics and Statistics, 46(1):149–162, 2017] defined the notion of ideal convergence of single sequences in 2–fuzzy 2–normed linear spaces. The aim of this paper is to generalize this notion to the double sequences in such spaces. For the sake of generalizing we define some concepts that contribute basically to outcomes that we came up with and study some basic properties of these new definitions.Publisher's Versio

Effects of Microwave Radiations on the Morphological and Biochemical Aspects of some Economically Important Herbs

The purpose of present work was to observe the effects of microwave radiation on some economically important herbs  by treating them with microwaved water. Plants studied were Brassica campestris, Lycopersicon esculentum, Pedilanthus tithymaloides, Portulaca grandiflora, Solanum melongena and Zinnia elegans. The results showed that microwave treated water and warm water both inhibited the growth of treated plants as there was significant decrease in the root and shoot length, diameter, fresh and dry weight, reduction in chlorophyll content, leaf area and enzyme activity of peroxidases which was also altered in all the treated plants. It was reported that the microwave radiations were harmful to treated plants and therefore the use of microwave appliances for heating purposes can affect the biochemical nature of food and ultimately can have an affect on human health
