BACKGROUND Ovarian adult-type granulosa cell tumors (GCTs) are characterized as low-malignant and late-recurrent ovarian tumors. Although some clinical and pathological prognostic factors have been reported, other factors have yet to be sufficiently investigated for necessary confirmation. The aim of this study was to test the correlation between clinical(More)
Rupture of a pregnant uterus in early pregnancy and an unscarred uterus are extremely rare, and some non-specific symptoms might appear before this occurrence. We report the case of a multiparous woman (gravida 3, para 2) with uterine fundal rupture in her early second trimester (17+ weeks of gestational age), who presented upper abdominal discomfort and(More)
The inflammatory process has direct effects on normal and abnormal wound healing. Hypertrophic scar formation is an aberrant form of wound healing and is an indication of an exaggerated function of fibroblasts and excess accumulation of extracellular matrix during wound healing. Two cytokines--transforming growth factor-beta (TGF-beta) and prostaglandin E2(More)
OBJECTIVE There is a possible correlation between endometriosis and an increased risk of epithelial ovarian cancer (EOC), but many uncertainties remain, including race, exposure or surveillance time, and surgical confirmation. Therefore, we carried out a large-scale, nationwide, controlled cohort study in the Taiwanese women to respond to these(More)
OBJECTIVE Clinical experience in the management of post-abortion hemorrhage is limited. CASE REPORTS Two women with severe post-abortion hemorrhage were reported. One case occurred after methotrexate treatment of Cesarean scar pregnancy and the other occurred after abortion surgery. Both patients were successfully treated with a double-balloon cervical(More)
Epidemiological evidence of relationships between endometriosis and epithelial ovarian cancer (EOC) has been obtained mainly from Western countries. Our goal was to determine the risk of EOC due to endometriosis in Taiwanese women. A retrospective cohort study was performed by linking to the National Health Insurance Research Database (NHIRD) of Taiwan. A(More)
AIM To evaluate the efficacy of uterine artery occlusion and myomectomy (UAO+M) for pregnant women with uterine leiomyomas who are undergoing cesarean section (CS). METHODS Seventy-two women with uterine leiomyomas undergoing CS for obstetrical reasons were enrolled into this case-control study. Thirty-six patients underwent UAO+M during CS (UAO+M group),(More)
OBJECTIVE Amniocentesis is a popular and effective prenatal diagnostic tool for chromosomal disorders. It is well-established that the risk of chromosomal abnormalities increases with maternal age; however, other related indications are seldom reported. Herein, we report our 30-year experience with amniocentesis from a single medical center, focusing on the(More)
This article aims to test the hypothesis that the risk of epithelial ovarian cancer (EOC) in women with endometriosis might be changed by enrolling different population. A nationwide 14-year historic cohort study using the National Health Insurance Research Database (NHIRD) of Taiwan and the Registry for Catastrophic Illness Patients was conducted. A total(More)
Adenomyosis of the uterus is defined as the presence of endometrial tissue, including glands and stroma, situated at least 2.5 mm below the endometrial-myometrial junction and widely distributed within the myometrium layer of the uterus. There is no consensus on the appropriate treatment for symptomatic uterine adenomyosis in women who want to preserve(More)
