Endoscopic Transpapillary Gallbladder Drainage for Acute Cholecystitis.

The mainstay of management of acute cholecystitis has been surgical, with percutaneous gallbladder drainage in patients deemed high risk for surgical intervention. Endoscopic management of acute cholecytitis with transpapillary and transmural drainage of the gall bladder is emerging as a viable alternative in high-risk surgical patients. In this article, we discuss the background, current status, technical challenges and strategies to overcome them, adverse events, and outcomes of endoscopic transpapillary gallbladder drainage for management of acute cholecystitis.

Use of "Parasep filter fecal concentrator tubes" for the detection of intestinal parasites in stool samples under routine conditions.

Parasitic gastrointestinal infections are a major cause of morbidity and mortality in the developing world, with stool microscopy being the mainstay of diagnostic practice. Both direct microscopy and concentration techniques can be utilized; direct microscopy may be time consuming and tedious; however clinical laboratories in developing countries lack trained staff who can effectively use concentration methods. In our practice we used the Parasep O and P filter concentrator tubes (manufactured by DiaSys Ltd, Berkshire, England. Product Code 146000) along with direct microscopic techniques and found that Parasep filters enhanced the ability to detect intestinal parasites that would have been missed on routine microscopy. We found the Parasep filter concentration method to be easy, cost-effective and reliable for routine stool examinations.

Causes of smoking in Pakistan: an analysis of social factors.

OBJECTIVE: To determine the factors contributing to the initiation and propagation of smoking in visitors to a major tertiary health center in Karachi, Pakistan. METHODS: Seven major contributing factors to the initiation and propagation of smoking were presented to consenting study participants (n=170) in a questionnaire. Participants were then requested to use their experience and opinion to rate each of the given factors on a scale of 1 to 5 regarding its importance as a causative factor in the initiation and propagation of smoking. Results were analyzed using SPSSv16.0. RESULTS: Preliminary analysis revealed occupational stress relief as the most important factor contributing to smoking with a mean score of 3.25 +/- 1.32. Peer pressure ranked second (Score 3.20 +/- 1.42). Domestic stress relief ranked third with a score of 3.19 +/- 1.32. Smokers gave lower rating than non-smokers to most factors. Younger participants gave higher ratings to peer pressure, and most participants were found to have begun smoking at a young age. CONCLUSIONS: Even though the addictive power of nicotine or stress may appear as a factor in middle aged smokers, the root of their habit lies in the initiation due to peer pressure.
