PURPOSE: Progesterone resistance is thought to be a major factor that contributes to progression of endometriosis. However, it is not clear what causes progesterone resistance in endometriosis. This study aimed to assess whether cytokines or peritoneal fluid can affect progesterone receptor (PR) expression in endometrial cells and to verify whether PR expression is reduced in endometriosis. MATERIALS AND METHODS: The PR-B/A ratio was measured via real-time polymerase chain reaction after in vitro culture, in which endometrial cells were treated with either tumor necrosis factor-alpha (TNF-α), interleukin-1 beta, or peritoneal fluid obtained from women with advanced-stage endometriosis. Immunohistochemistry was performed to compare PR-B expression between eutopic and ectopic endometrial tissues from women with and without advanced-stage endometriosis. RESULTS: The PR-B/A ratio was significantly decreased by treatment with either TNF-α (p=0.011) or peritoneal fluid from women with advanced-stage endometriosis (p=0.027). Immunoreactivity of PR-B expression was significantly lower during the secretory phase than during the proliferative phase in endometrial tissues from control subjects (p<0.001). PR-B expression was significantly reduced in the eutopic endometrium (p=0.031) and ovarian endometrioma (p=0.036) from women with advanced-stage endometriosis compared with eutopic endometrium tissues from control subjects. CONCLUSION: Progesterone resistance in endometriosis may be caused by proinflammatory conditions in the pelvic peritoneal microenvironment.

Coronary arteriovenous fistula (CAVF) is a rare condition defined as an anomalous termination of the coronary arteries. The etiology of CAVF is either congenital or acquired, and iatrogenic CAVF is most commonly caused by cardiovascular surgery or percutaneous intervention. Most of the prenatally diagnosed CAVFs were related to complex heart disease, and only few cases of an isolated CAVF have been reported to date. We successfully diagnosed an isolated CAVF by fetal echocardiography at 25.3 weeks of gestation. Accurate prenatal diagnosis resulted in the prompt decision for postnatal surgical correction, and the neonate thrived well without any complications.
