Background: Estrogen and progesterone immunoregulate the genital environment by expression of cytokines and growth factors.
Objective: To investigate the pattern of expression of T-helper cytokines during the ovarian cycle compared with women with chronic anovulation resistant to clomiphene citrate.
Hypothesis: Expression of T-helper cytokines in women with chronic anovulation may be different from the pattern in women with a normal ovarian cycle.
Methods: We evaluated 31 infertile women having laparoscopy for evaluation of tubal patency and evidence of ovulation in two groups during (a) the luteal phase (17 women) and (b) the follicular phase (14 women). A third group was composed of 14 women with polycystic ovarian syndrome, but they were resistant to clomiphene citrate for induction of ovulation and had laparoscopic ovarian cautery. Peritoneal fluid was collected during laparoscopy. Estimation of T-helper cytokine interleukin (IL)-2, tumor necrosis factor (TNF)-alpha, IL-4 and IL-6 in serum, peritoneal fluid and culture of the peritoneal mononuclear cells was performed by ELISA. Serum luteinizing hormone (LH), follicle stimulating hormone (FSH), prolactin, estradiol and progesterone were evaluated by the Vidas Parametric System.
Results: The LH : FSH ratio was significantly higher in the women with polycystic ovaries than in the ovulatory groups. IL-2 and IFN-gamma were more highly expressed in the follicular phase but the T-helper 2 cytokines IL-4 and IL-6 predominated in the luteal phase, serum, peritoneal fluid and culture of the peritoneal mononuclear cells. From the follicular to the mid-luteal phase, IL-6 increased three to fivefold in the serum and peritoneal fluid, but there was low expression with anovulation.
Conclusions: The peritoneal fluid levels of IL-4 and IL-6 are higher in the luteal phase. Low IL-6 levels in chronic anovulation may be a marker of resistance to clomiphene citrate.

Previous abdominal surgery (PAS) increases risk of small bowel obstruction (SBO) due to adhesions, and appendectomy (appy) is an independent risk factor for abdominal adhesion-related complications. Peritoneal inflammation, e.g.

Background: The beneficial impact of peritoneal dialysis (PD) catheter placement following cardiopulmonary bypass in young infants has been demonstrated. But the indications to start early peritoneal dialysis are not agreed upon.
Methods: This retrospective single center study was conducted to evaluate the performance of a clinical strategy for early PD start.

High-grade serous ovarian carcinoma (HGSOC) remains the most common and deadly form of ovarian cancer. However, available cell lines usually fail to appropriately represent its complex molecular and histological features. To overcome this drawback, we established OVAR79, a new cell line derived from the ascitic fluid of a patient with a diagnosis of HGSOC, which adds a unique set of properties to the study of ovarian cancer.

Endometriosis is a common gynecological condition affecting approximately 10% of women of reproductive age, characterized by the abnormal presence of endometrial-like tissue outside the uterus. Although endometriosis was first described over 300 years ago, its underlying mechanisms remain poorly understood, and accurate, prompt diagnosis continues to be challenging. Currently, there is a lack of effective, non-invasive diagnostic methods, and available treatments often come with significant side effects and high recurrence rates.

Background: Patients with peritoneal carcinomatosis often experience intestinal failure throughout the course of their disease, and total parenteral nutrition (TPN) can be used as a temporary solution or as a bridge to definitive cytoreductive surgery. Guidelines for TPN are well established for inpatients and in 2014, guidelines were established for the initiation of TPN for outpatients in a home setting. However, the safety and efficacy of home start TPN in advanced oncology patients remain unknown.
