Background: Imaging of the biliary tract for cholelithiasis and its complications has changed dramatically in recent decades. Ultrasonography (US) is the method of choice for detection of cholelithiasis and cholecystitis. In experienced hands it has a sensitivity of 96% and a specificity of 93% in imaging of biliary tract.
Aim and objective: To determine the sensitivity and specificity of USG in evaluation of cholelithiasis. To evaluate associated cholecystitis with cholelithiasis.
Material and methods: The study was conducted in Radio-diagnosis department. A retrospective cross-sectional study was conducted reviewing 46 patients requisitioned for USG abdomen scan. The information obtained was recorded on a self-designed data capture sheet. Data was analyzed using Microsoft Excel 2010.
Results: The study was conducted on 46 patients in which 27 (58.69%) were females and 19 (41.31%) were males.  Maximum number of patients was in the age group between 51 and 60 years, about 28%. A total number of patients scanned during ultrasonography were Fourty six (46) out of which Twenty four (24) patients were declared normal, Twenty two (22) patients were diagnosed with biliary tract diseases. The study shows that females are more susceptible to biliary tract diseases as compared males.
Conclusion: Biliary ultrasound (US) is a versatile and useful examination technique. Ultrasound is an accessible, inexpensive, and fast investigation for decision making in patients with biliary tract symptoms and for guidance in the further intervention. Ultrasonography plays important roles in the early diagnosis of anomalies of the biliary system. The most common disease among these patients was cholelithiasis, followed by the cholecystitis.

Stress mainly  refers to the perceived or actual threat on physical and/or psychological homeostasis of the human body. The stress-reduction approach based on mindfulness practices has recently enjoyed an explosion of interest from a variety of healthcare and epidemiological researchers. Disrupted homeostasis elicits the so called “stress response”, meaning the activation of central and peripheral neuroendocrine mechanisms responsible for various adaptive responses and behaviors The purpose of this study was to measure  the level of perceived stress among the students of Post Graduation. The study used a convenience sample of female and male college students. A scale for measuring the perceived stress level was adopted. PSS assess the perception of stressful experiences by asking the respondent to rate the frequency of his/her feelings and thoughts related to events and situations that occurred over the previous month in order to collect data from the respondents. Majority of the respondents agreed that they often perceived stress because of something that happened unexpectedly in the last month, they were unable to control the important things in their life, they were not confident enough to handle their personal problems or being unable to control irritations etc. Students often perceived stress when things were out of their control or they found it difficult to pile the things up because of uncontrollable situations.
