ABSTRACT
Objective: To evaluate the validity of 50 g oral Glucose Challenge Test as a screening tool for GDM in our population
Materials and Methods: This cross sectional study was carried out in Obstetrical clinic, Combine Military Hospital [CMH] Lahore. 100 women carrying singleton pregnancy between 20-35 years of age, booked in first trimester were included while patients with risk factor of GDM or with established type I or II DM were excluded from study. 50 g GCT was administered to patients between 24-28 weeks of gestation after informed consent. Venous plasma glucose levels after 1 hour of glucose load, were taken, using 140 mg/dl as a cut off value. Regardless of results of screening, all patients were tested with 100 g OGTT as a gold standard of diagnosis of GDM.. Validity of 50g GCT was calculated for sensitivity, specificity, positive and negative predictive value. Data was analysed by SPSS version 16
Results: Out of 100 patients, 19% were screen positive and 81% screened negative with 50g GCT. With100 g OGTT, true positive were 10 out of 19[52.6%] screen positive, and false positive were 9 out of 19[47.4%] screen positive. False negative were 3 out of 81[3.7%] screen negative, whereas true negative were 78 out of 81[96.3%] screen negative. Validity of 50 g GCT has been calculated to be having sensitivity of 76.92%, specificity of 89.6%, positive predictive value of 52.6% and negative predictive value of 96.2%
Conclusion: 50 g GCT is an effective screening tool for GDM between 24-28 weeks of gestation with adequate sensitivity and specificity
ABSTRACT
To determine the frequency of self-compliance to cervical screening guidance among the sexually active female gynecologists in tertiary care hospitals. To identify the possible barriers to effective screening in those who do not undergo cervical screening. Cross sectional study. This study was conducted in the obstetrics and Gynecology department of various tertiary care hospitals of Lahore from 1[st] Jun 2012 to 30[th] Nov 2012. Total 157 female gynecologists, serving in various positions in tertiary care hospitals of Lahore were interviewed by using a structured self reporting performa. The performa was designed to find out the number of gynecologists undergoing pap screening, and in those who fail to undergo screening the single most important barrier presumed to be preventing them from undergoing screening was also evaluated. In this study, only 3.1% of the subject population was found to be undergoing pap-screening, which reflects the national level of screening in urban areas,in sharp constrast to the studies being conducted in developed countries, with screening coverage rates of more than 80%. The prevalence of pap screening in the subject population is disappointingly low and drastic steps are needed to bring about a change in attitude of the subject population which cannot be brought about without changing the current culture of self-negligence and least prioritization for self, in the feminine part of our society
