ABSTRACT
OBJECTIVE: To determine the value of random urinary protein to creatinine ratio (UPCR) for diagnosis of proteinuria in pregnant women with preeclampsia. Preeclampsia is the most common complication of pregnancy and one of the main causes of maternal mortality. So, early diagnosis of preeclampsia is very important. MATERIALS AND METHODS: In this cross-sectional study 66 pregnant women suspected preeclampsia at ≥24 week of gestational age and BP ≥ 140/90 mm/Hg were checked by two urine samples of 10am and 4pm to determine random UPCR, as well as a 24-hour urine sample to evaluate 24-hour protein excretion. RESULTS: The result revealed that 74.2% of the studied population had significant proteinuria. There was a correlation between UPCR and 24-hour urine protein excretion. Pearson's correlation coefficient was 0.502 at 10am and 0.428 at 4pm. The best cutoff for the random urine protein to creatinine ratio at 10am was 0.470 with sensitivity and specificity equal to 87.5% and 84.2%, respectively. The best cutoff for the random UPCR at 4pm was 0.595 with sensitivity and specificity equal to 91.7% and 94.7%, respectively. CONCLUSION: Result of 24-hour urine collection showing random UPCR is considered as an appropriate situated method for emergency time.
ABSTRACT
OBJECTIVE: Birth trauma at delivery is a rare but significant prenatal complication. The aim of this study was to determine the incidence of birth trauma and risk factors related to fetal injury. MATERIALS AND METHODS: Birth trauma was evaluated in singleton fetuses with no major anomalies and with vertex presentations over a 3-year period from 2002 to 2005. One hundred and forty-eight neonates, who experienced birth trauma, were prospectively identified and compared with 280 normal neonates. Both groups were delivered vaginally. Maternal and infant characteristics were evaluated as possible risk factors for fetal injury. RESULTS: Among the 148 infants with birth trauma, nine had multiple injuries. The most common injury was cephalohematoma (n = 77). Other injuries included clavicle fractures (n = 56), brachial plexus paralysis (n = 13), asphyxia (n = 7), facial lacerations (n = 4), brain hemorrhage (n = 1), and skin hematoma (n = 2). Multiple regression analysis identified premature rupture of membranes, instrumental delivery, birth weight, gestational age, induction of labor, and academic degree of attendant physician at delivery as the most significant risk factors for birth trauma. CONCLUSION: The incidence of birth trauma was 41.16 per 1,000 vaginal deliveries. Induction of labor, premature rupture of membranes, academic degree of attendant physician at delivery, higher birth weight, and gestational age were associated with fetal injuries.
