ABSTRACT
To compare Wet smear and Gram staining for Clue cells in screening Bacterial Vaginosis [BV] in a clinical setting where laboratory facilities are not readily available. Cross-Sectional .This study was conducted in the Department of Microbiology, Basic Medical Sciences Institute Jinnah Postgraduate Medical Center Karachi. High vaginal swabs [HVS] were collected from Gyne and Obstetric Department of Jinnah Postgraduate Medical Centre, Karachi, from Jan 2005 to Feb 2007. One hundred and fifty high vaginal swabs [HVS] were collected from married females with or without complain of vaginal discharge. BV was diagnosed on the basis of clinical Amsel's criteria BV was diagnosed. Subsequently, clinical diagnosis was compared with laboratory based diagnosis for each woman. Two methods used were Wet Mount and Gram Staining. Out of total 150 cases, 100 females were complaining of vaginal discharge and after clinical assessment by Amsel's criteria 34 [34%] were diagnosed as cases of BV. Fifty females as [as controls] were those who were not complaining of any discharge. But among this group 8 [16%] were discovered to be suffering from BV. With the help of wet mount, the clue cells were visualized in 61 [40.7%] cases, while by Gram staining 54 cases [36.0%] were seen. BV screening is important as it affects both groups of females with or without complains of discharge. For easier recognition of clue cells, which are an excellent predictor of BV, wet mount is better as compared to Grams staining method
ABSTRACT
To determine the laboratory method that best predicts Bacterial Vaginosis. Descriptive Observational study. This study was conducted in the Department of Microbiology, Sindh Medical College [DUHS] and Basic Medical Sciences Institute, Jinnah Postgraduate Medical Centre, Karachi from Jan. 2005 to Feb. 2007. A total of 150 randomly selected women were included in this study from OPD of various tertiary care hospitals and family planning clinics of the city. In this study we compared and calculated the sensitivity, specificity and predictive value of positive and negative tests for wet mount, Gram stained vaginal smears and Gardnerella vaginalis [G.vaginalis] cultures with clinical sign Amsel's criteria [Gold standard], for the diagnosis of bacterial vaginosis [B.V]. We diagnosed 54 [36%] cases of bacterial vaginosis by Gram's staining method, 61 [41.7%] cases by Wet Mount method, and 42 [28.0%] cases by Amsel's criteria and 47 [31.3%] cases by culturing. Amsel's criteria were comparable with other laboratory tests for diagnosis of BV. Culture was laborious, expensive and least sensitive method
