Mother-to-child transmission (MTCT) of HBV is responsible for approximately half of the HBV transmission routes and continues to be a challenging problem worldwide. Even after the development of effective vaccines and clear World Health Organization guidelines toward HBV several decades ago, 1-9% newborns of HBV-carrying mothers still acquire HBV in early life as a result of in utero infection. The prevention of MTCT is of high importance, because chronically infected individuals function as a reserve for sustained HBV transmission, and 25% of them can develop asymptomatic liver cirrhosis and hepatocellular carcinoma. In this article, we review the canonical and novel HBV infection routes/mechanisms, influencing factors, diagnostic criteria, and interruption strategies for HBV MTCT. The preventative strategy of HBV MTCT has evolved from routine postpartum HB immune globulin (HBIG) plus HB vaccine schedules to administration of HBIG or nucleoside analogs during pregnancy and minimizing the exposure of maternal body fluids to the newborn during delivery.

Authors evaluated the outcome of intracapsular cesarean myomectomy by a prospective case-control study on 68 patients who underwent intracapsular cesarean myomectomy, compared with a control group of 72 patients with myomatosic pregnant uterus who underwent cesarean section (CS) without myomectomy. Mostly of removed myomas were subserous or intramural, fundal in 37 women (54.4%), corporal in 22 (32.3%) and peri-low uterine segment in 9 women (18.7%). The average myoma' size was 8 cm (1.5-20), in 40 women, with 8 myomas measuring 4-6 cm, 14 myomas between 10 and 12 cm and >13 cm in 6 patients. Difference in blood tests and surgical outcome in intracapsular cesarean myomectomy was non significant (p > 0.05). The average duration of hospitalization of intracapsular cesarean myomectomies was 5 days. There was no correlation between complications or duration of hospital stay and patient age, gravidity, parity or indication for CS. The intracapsular cesarean myomectomy could be a reliable, feasible and safe obstetric procedure. Meticulous attention to gentle hemostasis, sharp pseudocapsule dissection, adequate approximation of the myometrium edges and all dead spaces to prevent hematoma formation, can further increase the safety of the procedure, without significant complications by experienced obstetricians.
