Synopsis Endometriois has been associated with infertility, however the mechanism by which it affects fertility are still not fully understood. This manuscript reviews the proposed mechanisms of endometriosis pathogenesis, it affects on fertility and treatments of endometriosis-associated infertility. Theories on etiology of disease include retrograde menstruation, coelomic metaplasia, altered immunity, stem cells, and genetics. Endometriosis affects gametes and embryos, the fallopian tubes and embryo transport, and the eutopic endometrium; these abnormalities likely all impact fertility. Current treatment options of endometriosis-associated infertility include surgery, superovulation with IUI, and IVF. We also discuss potential future treatments for endometriosis related infertility such as stem cells transplantation and immune therapy.
Pelvic inflammatory disease (PID) is a common medical problem, with almost 1 million cases diagnosed annually. Historically, PID has been a clinical diagnosis supplemented with the findings from ultrasonography (US) or magnetic resonance (MR) imaging. However, the diagnosis of PID can be challenging because the clinical manifestations may mimic those of other pelvic and abdominal processes. Given the nonspecific clinical manifestations, computed tomography (CT) is commonly the first imaging examination performed. General CT findings of early- and late-stage PID include thickening of the uterosacral ligaments, pelvic fat stranding with obscuration of fascial planes, reactive lymphadenopathy, and pelvic free fluid. Recognition of these findings, as well as those seen with cervicitis, endometritis, acute salpingitis, oophoritis, pyosalpinx, hydrosalpinx, tubo-ovarian abscess, and pyometra, is crucial in allowing prompt and accurate diagnosis. Late complications of PID include tubal damage resulting in infertility and ectopic pregnancy, peritonitis caused by uterine and/or tubo-ovarian abscess rupture, development of peritoneal adhesions resulting in bowel obstruction and/or hydroureteronephrosis, right upper abdominal inflammation (Fitz-Hugh-Curtis syndrome), and septic thrombophlebitis. Recognition of these late manifestations at CT can also aid in proper patient management. At CT, careful assessment of common PID mimics, such as endometriosis, adnexal torsion, ruptured hemorrhagic ovarian cyst, adnexal neoplasms, appendicitis, and diverticulitis, is important to avoid misinterpretation, delay in management, and unnecessary surgery. Correlation with the findings from complementary imaging examinations, such as US and MR imaging, is useful for establishing a definitive diagnosis. (©)RSNA, 2016.
Objective To study whether infertility treatments, including IVF and non-IVF fertility treatments (NIFT), are associated with diseases of placental insufficiency in early gestation. First trimester placental volumes by ultrasound and chorionic villi weight during sampling (CVS) were performed to detect differences between pregnancies conceived spontaneously versus with fertility treatments. Design Retrospective cohort Setting Academic tertiary center Patients Women with singleton pregnancies undergoing CVS and first trimester ultrasound from 4–2007 to 11–2015. Interventions Estimated placental volume (EPV) was calculated from ultrasound images using a validated computation and CVS estimated tissue weight was performed using a validated visual analog scale. Main Outcomes Measured Adjusted linear regression was used to compare EPV and CVS weight based on mode of conception. Results 1977 spontaneous, 334 conceived with fertility treatments (133 NIFT, and 201 IVF) were included. Significant differences in maternal age, gravidity, hypertension and smoking status were identified. EPV and CVS weight were correlated with maternal age, gestational age, and maternal hypertension. Adjusted linear regression showed no difference in EPV in pregnancies conceived with fertility treatments versus spontaneously. CVS weight was significantly lower in the IVF conceptions in unadjusted univariate analyses. However, following adjusted regression, this was no longer significant. Conclusions Mode of conception does not appear to affect first trimester placental size. As differences in maternal age, hypertension and smoking status differ among the groups and are correlated to placental size, it may be the underlying patient population leading to abnormal placentation and insufficiency, not the fertility treatments utilized.
Background. Pelvic inflammatory disease (PID) rarely results in diffuse ascites. Severe adhesive disease secondary to PID may lead to the formation of inclusion cysts and even pelvic peritoneal nodularity due to postinflammatory scarring and cause an elevation of serum CA-125 levels. The constellation of these findings may mimic an ovarian neoplasm. Case. We report a case of a 22-year-old female who presented with multiple pelvic cysts and diffuse ascites due to Chlamydia trachomatis infection. The initial gynecologic exam did not reveal obvious evidence of PID; however, a positive Chlamydia trachomatis test, pathologic findings, and the exclusion of other etiologies facilitated the diagnosis. Conclusion. Chlamydia trachomatis and other infectious agents should be considered in the differential diagnosis of a young sexually active female with abdominal pain, ascites, and pelvic cystic masses. Thorough workup in such a population may reduce the number of more invasive procedures as well as unnecessary repeat surgical procedures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
