We conducted a pilot study followed by a large clinical trial in Nepal of the use of the capsular polysaccharide of Salmonella typhi (Vi) as a vaccine to prevent typhoid fever. In the pilot study, involving 274 Nepalese, there were no significant side effects of the Vi vaccine; about 75 percent responded with a rise in serum antibodies of fourfold or more. In the clinical trial, residents of five villages were given intramuscular injections of either Vi or, as a control, pneumococcus vaccine dispensed in coded, randomly arranged, single-dose syringes. There were 6907 participants, of whom 6438 were members of the target population (5 to 44 years of age); each was visited every two days. Those with temperatures of 37.8 degrees C or higher for three consecutive days were examined and asked to give blood for culture. Typhoid was diagnosed as either blood culture-positive or clinically suspected on the basis of bradycardia, splenomegaly, and fever, with a negative blood culture. Seventeen months after vaccination, the codes were broken for the 71 patients meeting the criteria for either culture-positive or clinically suspected typhoid. The attack rate of typhoid was 16.2 per 1000 among the controls and 4.1 per 1000 among those immunized with Vi (P less than 0.00001). The efficacy of Vi was 72 percent in the culture-positive cases, 80 percent in the clinically suspected cases, and 75 percent in the two groups combined. These data provide evidence that Vi antibodies confer protection against typhoid. Surveillance continues to determine the duration of Vi-induced immunity.

During the first six months of 1983, an epidemic of serogroup A meningococcal meningitis occurred in the Kathmandu valley of Nepal, resulting in 875 cases and 95 deaths. The annual attack rate was 103 cases per 100,000 population, with a peak attack rate occurring in April. Epidemic meningococcal disease had not been recognized previously in Nepal. Early in 1984, a review of hospital-based data on pyogenic meningitis in Kathmandu showed three times as many cases per month compared with the same period the previous year, suggesting that a recurrent epidemic was unfolding. Beginning in February 1984, a vaccination campaign directed at a high-risk target population of people aged 1-24 years was launched; over 329,000 doses of bivalent A/C meningococcal vaccine were given, achieving approximately 64% coverage of the target population. A dramatic decline in the number of new meningitis cases occurred coincident with the initiation of the mass vaccination campaign. This experience demonstrates that it is possible, with appropriate surveillance efforts, to detect an evolving epidemic of meningococcal disease early in its course and to institute control measures in advance of the expected epidemic peak.

This article summarizes the geotechnical effects of the 25 April 2015 M 7.8 Gorkha, Nepal, earthquake and aftershocks, as documented by a reconnaissance team that undertook a broad engineering and scientific assessment of the damage and collected perishable data for future analysis. Brief descriptions are provided of ground shaking, surface fault rupture, landsliding, soil failure, and infrastructure performance.

Introduction: High risk pregnancy is a major cause of morbidity and mortality in a developing country. These patients are recognized in the initial prenatal office visit as they have a poor obstetrical history or a well recognized medical complication however; pregnancy becomes high risk because they develop unexpected complications in the course of otherwise normal pregnancies. The objective of this study is to identify various type of high risk pregnancy and fetal outcome. Methods: This was a descriptive study conducted in Shree Birendra military hospital over a period of 9 months. Patients were recognized as high risk during antenatal visit and during admission. They were followed till delivery. The case records of all high risk pregnancy with their fetal outcome were analyzed. Statistical analysis was done using simple percentage. Results: Total deliveries during study period was 626. High risk pregnancy identified were 99 (15.81%). Previous lower segment cesarean section was the most common identified high risk pregnancy 34 (5.43%) followed by young primigravida 3.19%, breech 2.23%. There were total 13 low birth weight baby (13.13%) and 2 stillbirth (2%) as fetal outcome. Conclusion: Identification of high risk pregnancy during antenatal period will reduce adverse perinatal outcome.

Introduction: The management of gynecological emergencies is essential for the preservation of the life of affected woman, her sexual functions and fertility particularly in disease conditions that threaten her life. The main objective of the study is to determine the proportion of the surgical emergencies among gynecological surgeries in a tertiary care center. Methods: This is a descriptive cross-sectional study conducted in the department of gynecology and obstetrics in Shree Birendra Hospital, Kathmandu, Nepal from April 2013 till March 2017. Ethical approval was taken from the Institutional Review Committee (IRC) in November 2019. This study was conducted among 515 gynecological surgeries by using convenience sampling methods. Point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data. Data were analyzed using EXCEL software. Results: In our study, the proportion of surgical emergencies among total gynecological surgeries performed in the department of gynecology and obstetrics in Shree Birendra Hospital was 120 (23.30%). The highest number of surgical emergencies was observed in the age group of 20-29 years old, followed by less than 19 years of old age group. Ectopic pregnancy accounting for 85 (70.83%) is found to be the most common surgical emergencies in our study. Out of all surgical emergency cases, most of them underwent salpingectomy 65 (54.16%) followed by salpingectomy with tubal ligation 20 (16.16%). Conclusions: Surgical emergencies among gynecological surgeries are found to be in greater proportion in the department of gynecology and obstetrics in Shree Birendra Hospital. Ectopic pregnancy accounted for more than half of the diagnoses in this study.
