Indicate the type of study whether the study is descriptive or analytic.

For each abstract: 1. Indicate the type of study whether the study is descriptive or analytic. If the study is analytic study, indicate whether it is a case control, cohort or an experimental study. (Each study 2 points) When the study is a case control, cohort or an experimental study, construct one 2×2 table summarizing result of the study. 2×2 table should be presented as follows. Outcome Total Exposure atb+c+d 2.1 For the 2×2 tables, indicate the exposure and the outcome studied. (Each study 2 points) 2.2 Give the value of the four cells of the table (a,b,c,d), the value of the two marginal totals (atc, b+d or a+b, c+d), and the grand total (a+b+c+d). (Each study 4 points) 2.3 Calculate the appropriate measure of association for each abstract. (4 points) A 10 year audit of a gynecological surgeries performed in the pediatric age group at the Jos university teaching hospital. Afr J Pediatric Surg. 2010Sep-Dec; 7(3): 178-80. Surgeries performed for the gynecological conditions in children and adolescents are not common in our environment. Adequate facilities and the risk to perform the required procedure may also be lucking. We were interested in reviewing the practice of pediatric gynecological surgery in our facility. A retrospective study of case files and theater records of children below the age of 16 years who had surgeries at the Jos university teaching hospital over a 10-year period was undertaken. A total of 89 surgeries were performed in this age group during the period under review. Twenty-eight (33.4%) of the patients were below the age of 11. The most common surgical procedure was for the management of septic abortion (21.3%). Correction of congenital malformations of the genital tract accounted for 21.4% of the surgeries performed. Fourteen (15.7%) laparotomies were performed for ovarian cysts. Association between HSV-2 and HIV serostatus in pregnant women of known HIV serostatus attending Mulago hospital antenatal clinic, Kampala, Uganda. J Infect Dev Ctries. 2009 Dec 15;3(10): 803-6 Studies show that STIs such as HSV-2 and HIV-2 increase the probability of HIV-1 acquisition and enhance transmission by increasing susceptibility and infectiousness respectively. This study included 50 pregnant women who were HIV positive and 200 pregnant women who were HIV negative and were aware of their serostatus. The proportion of HSV-2 was 86% among the HIV positive cases and 62% among the HIV negative controls. The odds of having HSV-2 was higher in HIV positive mothers than in the HIV negative mothers.
