Intrauterine devices (IUDs) have a low complication rate and minimal side effects and are pervaded contraceptive methods. Perforation of the uterus by an IUD is very rare. But perforation of the uterus is one of the most serious complications associated with insertion of IUD. During the puerperium when the uterus is small and the uterine wall is thin the risk of perforation increase. The frequency has been estimated between 0.05 and 13 per 1000 insertions. When the IUD strings are not visible during pelvic examinations, physicians make efforts to locate the IUD. We experienced a laparosopic removal of perforated intrauterine device, which had been inserted on postpartum 5 th week, at posterior lower segment of uterus with intrauterine pregnancy. So we report a case with a brief review of the literature.

A bartholin gland cysts and abscesses are common problems in women of reproductive age. Although the cysts are usually asymptomatic, they may become enlarged or infected and cause significant pain. Bartholin gland abscesses usually develop over two to four days and can become larger than 8 ㎝ by literature but huge bartholin abscess is very rare. A number of vulvar and vaginal lesions can mimic bartholin gland cysts or abscesses and should be included in the differential diagnosis. So we report a case of hemorrhagic huge bartholin abscess with a brief review of the literatures.

Uterine papillary serous carcinoma (UPSC) has been recognized as an aggresive tumor with early and deep myometrial invasion, frequent lympho-vascular space involvement, and a high relapse rate. It has also been shown that deep myometrial invasion cannot p

Purpose: The objective of the present study was to predict the gestational age at preterm birth using artificial neural networks for singleton pregnancy. Methods: Artificial neural networks (ANNs) were used as a tool for the prediction of gestational age at birth. ANNs trained using obstetrical data of 125 cases, including 56 preterm and 69 non-preterm deliveries. Using a 36-variable obstetrical input set, gestational weeks at delivery were predicted by 89 cases of training sets, 18 cases of validating sets, and 18 cases of testing sets (total: 125 cases). After training, we validated the model by another 12 cases containing data of preterm deliveries. Results: To define the accuracy of the developed model, we confirmed the correlation coefficient (R) and mean square error of the model. For validating sets, the correlation coefficient was 0.839, but R of testing sets was 0.892, and R of total 125 cases was 0.959. The neural networks were well trained, and the model predictions were relatively good. Furthermore, the model was validated with another dataset of 12 cases, and the correlation coefficient was 0.709. The error days were 11.58±13.73. Conclusion: In the present study, we trained the ANNs and developed the predictive model for gestational age at delivery. Although the prediction for gestational age at birth in singleton preterm birth was feasible, further studies with larger data, including detailed risk variables of preterm birth and other obstetrical outcomes, are needed.
