The influence of serum substituents on serum-free Vero cell conditioned culture media manufactured from Dulbecco's modified Eagle medium in mouse embryo culture

OBJECTIVE: This study was conducted to examine the influences of supplementation of the serum substituents and available period of serum-free Vero cell conditioned media (SF-VCM) manufactured from Dulbecco's modified Eagle medium cultured with Vero cells for in vitro development of mouse preimplantation embryos. METHODS: A total of 1,099 two-cell embryos collected from imprinting control region mice were cultured in SF-VCM with 10% and 20% human follicular fluid (hFF), serum substitute supplement (SSS), and serum protein substitute (SPS). Development of embryos was observed every 24 hours. Results between different groups were analyzed by chi-square test, and considered statistically significant when P-value was less than 0.05. RESULTS: The rates of embryonic development cultured in SF-VCM supplemented with serum substituents were significantly higher compare with serum-free group (P < 0.05). The rates of embryonic development after 48 hours (morula< or =) and 96 hours (blastocyst< or =) were significantly higher in 20% SSS and 10% SPS than in 20% hFF supplementation (P < 0.05). And the rates of embryonic development after 96 hours (hatching blastocyst< or =) were significantly higher in 10% SPS (94.5%) than in 20% SSS (82.6%) and 20% hFF supplementation (68.5%). The rates of embryonic development according to storage period of the SF-VCM supplemented with 10% SPS showed no significant difference between control, 2 weeks and 4 weeks group. However developmental rate in 6 weeks storage group was significantly lower than other groups. CONCLUSION: The rate of embryonic development after 96 hours (hatching blastocyst< or =) was significantly higher in SF-VCM supplemented with 10% SPS. And storage period of media up to 4 weeks did not affect on embryonic development.

Six cases of laparoscopic assisted neovaginoplasty using pelvic peritoneal flap in MRKH syndrome / 대한산부인과학회지

Vaginal agenesis is rare gynecologic condition, and the most common etiology is Mayer-Rokitansky-Kster-Hauser (MRKH) syndrome, characterized by the absence of uterus and vagina and presence of normal ovaries and tubes. In such patients, the evaluation for associated malformations as well as careful non-surgical and surgical approach are essential. The neovaginoplasty is an important issue for these patients in regard of functional and psychological standpoint. There are many options available for creation of neovagina. We report six cases of laparoscopic assisted neovaginoplasty using pelvic peritoneal flap.

One case of vulva metastasis from cervical squamous cell carcinoma / 대한산부인과학회지

Metastasis to the skin occurs rarely in gynecologic cancer. Although carcinoma of the cervix is the fifth most common malignancy in Korean women, cutaneous involvement originating from cervical cancer is unusual. Common pattern of occurrence is multiple nodule in abdomen, vulva, lower extremities. We report a case of metastasis from squamous cell carcinoma of cervix to vulva. The patient was diagnosed with cervical cancer IIA. The extensive skin lesion on the vulva occurred 3 months after neoadjuvant chemotherapy, radical hysterectomy and concurrent chemoradiation. We have experienced such a case and report the case with brief review of literatures.

Three cases of vaginal evisceration after laparoscopic hysterectomy / 대한산부인과학회지

Vaginal evisceration is a rare but life threatening complication of gynecologic surgery. Most of them occur after abdominal or vaginal hysterectomy. The incidence after laparoscopic hysterectomy is unknown. The incidence of evisceration in the patients undergoing laparoscopic hysterectomy in our hospital was 0.1 %. The rapid recovery after laparoscopic hysterectomy, compared with abdominal hysterectomy, is widely acknowledged. Swift return to everyday activities and early resumption of intercourse could predispose to rupture of vaginal vault. Upon discharge, patients undergoing laparoscopic hysterectomy should be given careful instructions to avoid coitus until complete healing of vaginal vault. We described three cases of vaginal evisceration after laparoscopic hysterectomy including a review of the literature.
