ABSTRACT
Background: Candida species are known to be the most common fungal pathogens isolated from blood cultures of neonates. Recent reports from our country indicates trend towards an increasing prevalence of non-albicans candidemia. Candida species possess a number of virulence factors which enable them to cause hematogenously disseminated infections in susceptible hosts with increased morbidity and mortality. Objective of current study was to know the prevalence of nonalbicans candidemia in neonates and their antifungal susceptibility pattern. Methods: Blood samples from suspected cases of neonatal septicaemia were subjected to culture, incubated for 7 days and subcultures performed. Culture yielding pure growth of Candida were included for the study and identified by standard methodology. Antifungal susceptibility was performed. Results: A total of 255/500 (51%) cases were blood culture positive. Pure growth of Candida species was isolated from 52/255 (20.39%) cases. A total of 52 Candida isolates were obtained over a period of one year accounting for 20.39% of all neonatal septicemia cases. Among 52 isolates, 14/52 (26.92%) were Candida albicans, followed by C. tropicalis 19/52 (36.53%), C. glabrata 10/52 (19.23%), C. parapsilosis 4/52 (7.69%), C. guillermondii 2/52 (3.84%) and C. krusei 1/52 (1.92%). C. tropicalis, the most common species isolated, was 91 per cent susceptible to fluconazole, whereas C. parapsilosis and C. glabrata showed lower sensitivity rates of 67.8% and 62.5% respectively. Conclusion: In this study non albicans candida was the common isolate & they showed decreased resistance to Fluconazole. In neonatal septicemia speciation& antifungal susceptibility may help in management.
ABSTRACT
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, Hyderabad Methods: 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.
ABSTRACT
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.
