The true HCV MTCT and de-carrier rates were found to be much higher and lower than those reported previously. The maternal liver dysfunction (sALT >or=110 IU/mL) and blood loss (>or=500 g) at delivery are the next risk factors to maternal viral load (>or=10(5) copies/mL) for MTCT.

PurposeTo determine whether the cycle regimens that are used for endometrial preparation are associated with the birthweight (BW) after assisted reproductive technology (ART) using frozen‐thawed embryo transfer (FET).MethodsThe BW of singletons who were born by ART using FET was compared retrospectively, according to whether a FET was conducted in a hormone replacement therapy cycle (HRT, n = 403) or an ovulatory cycle (OVL, n = 117). The BW after timed intercourse (NAT, n = 162) also was investigated.ResultsThere were no significant differences in the age of the mothers, percentage of primiparas, gestational periods, Body Mass Index, and sex ratio between the HRT and OVL cycles. The average BW from HRT was significantly greater than that of OVL. The BW from HRT was also greater, compared with NAT, while statistical significance was not achieved between OVL and NAT. The putative factors affecting the BW, such as ovarian stimulation protocols, endometrial thickness, and the stage and quality of embryos, could not explain the difference in the BW between the HRT and OVL cycles.ConclusionAn increased BW from ART using FET seems to be ascribable to conditions of the endometrium, but not cryopreservation procedures per se, which might provide a mechanistic framework for understanding heavier neonates who are born by FET.

Retrorectal epidermoid cyst is one of the developmental cysts which arise from remnants of embryonic tissues. We report a rare case of retrorectal epidermoid cyst, initially diagnosed as an ovarian tumor. Serum SCC value as tumor marker was elevated to the high level. Laparoscopy revealed ovaries, uterus and other pelvic organs were all normal. This tumor existed in the retroperitoneal cavity and compressed the rectum. Later, complete tumor resection was performed by laparotomy. Histological study revealed the epithelium of this tumor consisted of only squamous cells without atypia, and the diagnosis of this tumor was retrorectal epidermoid cyst. Retrorectal epidermoid cyst is very rare, and difficult to diagnose before surgery. However, if we have-knowledge of developmental cysts, and by careful digital examination and image diagnosis, a differential diagnosis can be made.

We investigated the prevalence of measles-sensitive pregnant women and the clinical usefulness of measles vaccination in postpartum women. Measles antibody levels were measured in 751 pregnant women. Forty-four women were vaccinated postpartum, and screened for antibody levels and adverse effects 1 month after vaccination. The prevalence of measles-sensitive pregnant women was 10-20%, with the highest prevalence in those under 24 years of age. Almost all (97.7%) vaccinated women acquired immunity, and did not show any adverse effects. Serum measles antibody levels should be determined in all pregnant women as a screening tool, and sensitive women should be vaccinated immediately after delivery.

Our results suggest that there is a positive association between defensin levels and neutrophil activation in pregnant and post-partum women.
