RESUMO

OBJECTIVE: To evaluate the diagnostic performance of 50-g glucose challenge test for diagnosis of gestational diabetes. MATERIAL AND METHOD: A retrospective study was conducted by reviewing the medical records of pregnant women who had a 50-g glucose challenge test of 140 mg/dL or higher and followed by a 100-g glucose tolerance test. Results were categorized in 10 mg/dL increments. Gestational diabetes was diagnosed using National Diabetes Data Group criteria. RESULTS: The present study included 2,226 cases from universal screening of 11,084 pregnant women. The incidence of gestational diabetes was 3.2% (351/11,084). Only 1.6% (6/374) of patients with positive screening results of less than 145 mg/dL had gestational diabetes. All of the 6 women undiagnosed by this threshold were gestational diabetes class A1 and had at least one risk factor Of 1,875 women, seven cases (0.4%) would be over diagnosed as gestational diabetes if 100-g glucose tolerance test was not performed after a result of 50-g glucose challenge test of > or = 250 mg/dL (99.6% specificity, 85.8% negative predictive value, 12.3% sensitivity and 86.0% positive predictive value). CONCLUSION: A 50-g glucose challenge test may be used as a diagnostic test when the value is > or = 250 mg/dL. The present data suggested that the value of glucose screening of > or = 145 mg/dL can be used as a threshold for a positive test in the low risk women.

RESUMO

OBJECTIVE: To identify the risk factors for cesarean hysterectomy. MATERIAL AND METHOD: A case-control study was conducted by reviewing the medical records of pregnant women delivered in King Chulalongkorn Memorial Hospital between January 1994 and December 2004. Cases included pregnant women who underwent hysterectomy immediately or within 24 hours after cesarean delivery, whereas control referred to pregnant women who underwent cesarean section at the same period. RESULTS: Of the 109,005 deliveries, twenty-seven women (0.25/1000-delivery) underwent cesarean hysterectomy. With multivariate analysis, the risk factors significantly associated with peripartum hysterectomy were placenta previa (adjusted OR = 67.96, 95% CI = 15.32, 301.46) and multiparity (adjusted OR = 7.30, 95% CI = 1.24, 43.19). When compared to controls, cases with cesarean hysterectomy had higher incidence of maternal and neonatal morbidities, needed more blood transfusion and required longer hospital stays. Operation performed in daytime found to have less mean blood loss (1,766 ml) compared to operation at nighttime (5,730 ml). CONCLUSIONS: Placenta previa and multiparity were significant risk factors of cesarean hysterectomy. Cesarean section in these cases should be done by experienced obstetricians with good preoperative care and if possible, during the daytime. Before an operation, each patient and her family should be counseled and informed regarding the risk for complications included hysterectomy.

RESUMO

OBJECTIVE: To compare the effectiveness of single hydrogen peroxide vaginal douching and a single oral dose of metronidazole for the treatment of bacterial vaginosis. METHOD: A randomized trial was performed at the outpatient clinic in King Chulalongkorn Memorial Hospital. 142 patients diagnosed as having bacterial vaginosis were randomly allocated into two groups. The subjects in the first group were douched with 20 milliliters of 3 per cent hydrogen peroxide and received an oral placebo. The subjects in the second group received oral metronidazole 2 grams orally and were douched with a placebo. The cure rate in each group was assessed using Amsel's criteria 2 weeks after treatment. RESULT: The cure rate in the subjects treated with hydrogen peroxide douching was lower than the cases who received oral metronidazole (62.5% versus 78.6%, p-value = 0.036). Rate of gastrointestinal side effects in metronidazole group was higher than in the hydrogen peroxide group (48.6% versus 13.9%, p-value < 0.001). CONCLUSION: Single hydrogen peroxide vaginal douching was less effective than a single oral dose of metronidazole in the treatment of bacterial vaginosis.

RESUMO

OBJECTIVE: To determine whether random urinary protein-to-creatinine ratio correlated with the quantitation of 24-hour proteinuria in cases of preeclampsia. DESIGN: Cross-sectional descriptive study. SUBJECTS: Pregnant patients hospitalized in the obstetric ward, King Chulalongkorn Memorial Hospital due to preeclampsia. METHOD: The random urine specimens were obtained from the eligible subjects for protein-to-creatinine ratio determination, the subjects were then instructed to collect 24-hour urine samples for protein measurement. RESULTS: Twenty-five pregnant patients completed the study. There was a strong correlation between the random urinary protein-to-creatinine ratio and the quantitation of 24-hour proteinuria (r = 0.929, p < 0.001). CONCLUSION: The presented data support a strong correlation between random urinary protein-to-creatinine ratio and quantitation of 24-hour proteinuria in hospitalized pregnant patients with preeclampsia.
