We report a rare case of a cavernous transformation of portal vein (CTPV) thrombosis accompanied by Thalassemia and thrombophilia during pregnancy that was successfully treated by low molecular weight heparin. The clinical presentation, diagnosis and the treatment are discussed.
Breech presentation is the most common of malpresentations, occurring in 3-4% of all term deliveries. The fetus may adopt breech presentation because of many factors. In the past, the mode of delivery (vaginal or abdominal) was determined by clinical considerations. Current recommendations are for cesarean section in all breech presentations. Successful External Cephalic Version is the only effective way to avoid cesarean section in breech presentation. Considering success rates and related factors, this review article emphasizes the importance of considering ECV to every woman with breech presentation.
Chickenpox during pregnancy is very uncommon and is known to cause fatal malformation during the first half of pregnancy. The infection during pregnancy is also associated with maternal morbidity and mortality. Furthermore, there may also be neonatal complications. Thus, any pregnant woman with Varicella infection should be hospitalized and followed-up closely. In this review, we examined the literature on Varicella Zoster during pregnancy with regard to prevalence, prenatal diagnosis, management and prevention.
OBJECTIVE: The purpose of this study was to compare complications and outcome of preterm neonates weighing < or =1,500 g who developed necrotizing enterocolitis (NEC) to neonates without NEC. STUDY DESIGN: During January, 1995 to December, 1998, 211 live preterm neonates were born with birth weight < or =1,500 g. A cross sectional prospective study was designed and two groups were defined: 17 neonates who developed NEC and 194 without NEC. Multiple logistic regression analysis was performed to determine independent risk factors for the development of NEC. RESULTS: The prevalence of NEC was 8% (17/211). The following complications were found to be significantly higher among mothers of neonates with NEC: mild pre-eclampsia (11.8 vs. 2.6%, p=0.04); severe pre-eclampsia (35.5 vs. 12.9%, p=0.01); chronic hypertension (29.4 vs. 5.7%, p<0.001) and low birth weight (968 +/- 233 vs. 1,123 +/- 257 g, p=0.02). In contrast, mean maternal age, mean gestational age at delivery and parity were not significantly different between the groups. A multivariate analysis including the following factors: maternal hypertensive disorders, pregestational diabetes mellitus, birth weight and gestational age at delivery, found only maternal hypertensive disorders to be independent risk factors for NEC (OR=5.21, 95% CI 1.64-16.58). CONCLUSIONS: Maternal hypertension is an independent risk factor for the development of NEC in preterm neonates weighing <1,500 g. Thus, maternal vascular disorders may play an important role in the pathophysiology of NEC.
