Objective structured practical examination as a formative assessment tool for IInd MBBS microbiology students

Background: Assessment drives learning. It is well known that conventional or Traditional Practical Examination (TPE) has several limitations, especially in terms of subjectivity. In OSPE the procedures are standardized, so objectivity is ensured and also reliability maximized. Objectives of the study were to compare TPE & OSPE examination in formative assessment for IInd MBBS microbiology students on the topic culture media and to obtain feedback from students attending OSPE, and faculty.Methods: 76 students were taught about culture media and simultaneously were sensitized about OSPE and TPE, which followed the next week. Informed consent was taken. All students were randomly divided into 2 batches (TPE and OSPE) based on roll call. 71 students were tested, 33 for OSPE and 38 for TPE. Eight OSPE stations were set up with 8 culture media, plus a rest station after station 4. TPE students went for viva-voce to one examiner for same eight culture media. Both OSPE and TPE students were evaluated for a score of 20. OSPE students and the faculty were given a pre-validated questionnaire for feedback.Results: Mean scores, standard deviation (SD) and “p” values were calculated using the T-test from the scores obtained. The mean scores for OSPE and TPE were found to be statistically significant- p-value <0.01. Feedback from OSPE students & faculty was also evaluated.Conclusions: OSPE is more structured and eliminates examiner bias better, and should be practiced in formative assessments and also be introduced in summative assessments

Seroprevalence of dengue virus in a tertiary care hospital, Andhra Pradesh, South India

Background: Dengue fever and Dengue Haemorrhagic fever (DF/DHF) is an acute viral disease caused by Dengue virus. The infection is transmitted by the bite of an infected female mosquito- Aedes aegypti. The Dengue virus causes significant morbidity and mortality in many parts of the world, including India, where it was first isolated in Calcutta, West Bengal during 1945. This study was conducted to know the seroprevalence of Dengue virus in a tertiary care hospital, HyderabadMethods: Blood for serological studies are carefully collected taking due universal precautions from suspected DF/DHF cases (a) as soon as possible after hospital admission or attendance. All the patients were screened for anti-Dengue IgG and IgM antibodies By Enzyme Immunoassay. The study period was 18 months from 2012. Results: From a total of 1327serum samples tested were screened for Dengue IgM and IgG among which 706(53.2%) were positive. 125(17.7%) were only IgM positive and 198(28.05%) of the tested samples showed only IgG positive. 383(54.25%) of the tested samples revealed positive for both IgM and IgG antibodies. Conclusion: Surveillance is prerequisite for monitoring the dengue situation in the area and should be carried out regularly for early detection of an impending outbreak and to initiate timely preventive and control measures

To evaluate the prevalence of female genital tuberculosis in Hyderabad

Background: Tuberculosis (TB) is an increasing public health concern worldwide. It is one of the most important causes of infectious morbidity and mortality. Genital TB is one form of extra pulmonary TB and is not uncommon, particularly in communities where pulmonary TB is prevalent. The objective of the study was to evaluate the prevalence of female genital tuberculosis in Hyderabad and its presentational symptoms and methods of diagnosis.Methods: A total of 1102 cases of suspected genital TB who had been registered and treated in the AIMSR and few selected government urban health post and private hospitals and clinics in different zones of Hyderabad, from 2012 January to 2013 March were retrospectively and prospectively studied. From this group, 23 women were diagnosed as having genital TB based on the standard pathological and microbiological criteria of tissue specimens. Results:Out of 23 cases diagnosed as having genital tuberculosis, 3 patients (13.04 %) presented with abdominal or pelvic pain. In 17cases (73.91%) tuberculosis was diagnosed during studies performed to evaluate the cause of their infertility, and the most common diagnostic procedure was endometrial curettage. Remaining 3 cases (13.05 %) have past, present or contact history of tuberculosis. Female genital TB accounted for 2.08 % of all tuberculosis patients in this study.Conclusions: This study indicates the presence of a strong relationship between genital TB and infertility; therefore genital TB would be more frequently diagnosed if this possibility was considered in the evaluation of every infertile patient in areas where tuberculosis is endemic
