From Finland : How to increase health issues in endometriosis patients

Dr. Henna-Riikka Rossi and associates from the University of Oulu, Oulu, Finland have published their recent prospective cohort study on possible existing comorbidities of endometriosis patients in the journal Fertility and Sterility. Endometriosis is an estrogen-dependent chronic ailment affecting about 6-10% of women which may be associated with painful periods, dyspareunia, chronic pelvic pain, abdominal bloating, nausea, fatigue, and sometimes depression, anxiety, and infertility. Besides, this common gynecological disorder seems to have an increased risk of other health issues like…

Is the pathogenesis of endometriosis hidden in immune-related gene profiles ?

Yanan He and colleagues from the Department of Gynecology, Harbin Medical University, China  have published their manuscript on potential immune markers in endometriosis in a recent issue of  “Journal of Immunology Research” Pathophysiologic mechanisms involving endometriosis are complicated and have various parameters like local inflammation, proliferation, invasion, and angiogenesis of endometrial cells. All these have not been well understood yet. The majority agrees that immune factors have a major role in the viability of ectopic endometria with depressed immunosurveillance and…

Rare but important entity: perineal endometriosis

Dr. Zhu and colleagues from Peking Union Medical College Hospital have published their retrospective research on "surgically treated perineal endometriosis cases" in a recent issue of BMC’s Women’s Health. Perineal endometriosis is a rare type of endometriosis accounting for at most 0.37% of women consulting for treatment of endometriosis. A literature search starting from 1923 for perineal endometriosis revealed around three hundred cases till 2021. Diagnosis and therapy could be problematic mainly due to its rarity and low awareness of…

Antimicrobial agent ornidazole yields promising effects in an animal model of endometriosis

Xiaoduo Qin and collaborators from Chinese medical centers, have published their results on the role of ornidazole using an experimental rat model in a recent issue of the periodical “Gynecologic and Obstetric Investigation”. Progression of endometriotic foci depends on the presence of an adequate blood supply, i.e. angiogenesis, and chronic inflammatory response is also closely related in its pathogenesis. Ornidazole is a well-known antimicrobial agent with a strong anti-inflammatory effect besides possessing some antiangiogenetic and anticancer properties. In this regard, ornidazole could…

TSH receptor antibodies show promising results in the diagnostic workup of endometriosis

Dr. Svensson with collaborators from the Swedish Lund University has published their results on the possible role of TSH receptor antibodies as biomarkers in endometriosis diagnosis in a recent issue of “European Journal of Obstetrics & Gynecology and Reproductive Biology”. Possible pathophysiologic mechanisms in endometriosis include molecular abnormalities and a defective immune system enabling the growth of ectopic endometria. Besides, the presence of a wide range of autoimmune diseases, including thyroid disorders is known to be increased in endometriosis patients.…

Understanding what we see: endometriosis laparoscopic appearance and microscopic verification

Chia-Sui Weng and colleagues from the Mayo Clinic, USA have published their results on laparoscopic appearances and microscopy of endometriotic lesions in “The Journal of Minimally Invasive Gynecology”. Even though the diagnosis of endometriosis has evolved greatly with advanced imaging techniques surgery with histopathologic evaluation is still the diagnostic gold standard. Nevertheless, this diagnostic pathway may have difficulties due to various factors depending on the patient and surgical pathologist. Laparoscopic biopsies yield opportunities in confirming endometriosis via the pathologist’s microscope…
