Vasileios Charalampakis, Abd A Tahrani, Ahmed Helmy, Janesh K Gupta, Rishi Singhal
One of the most effective methods to tackle obesity and its related comorbidities is bariatric surgery. Polycystic ovary syndrome (PCOS) and endometrial hyperplasia (EH), which are associated with increased risk of endometrial carcinoma, have been identified as potentially new indications for bariatric surgery. PCOS is the most common endocrine disorder in women in the reproductive age and is associated with several components of the metabolic syndrome such as obesity, insulin resistance and hypertension. EH is a pre-cancerous condition which arises in the presence of chronic exposure to estrogen unopposed by progesterone such as both in PCOS and obesity...

: Glucose-regulated protein (GRP)-78, the key regulator of endoplasmic reticulum (ER) stress, is associated with endometrial cancer (EC) development and progression. However, its role in the continuum from complex atypical hyperplasia (CAH) to EC is unknown and the focus of this study. METHODS: 252 formalin-fixed, paraffin-embedded endometrial biopsies from patients with CAH diagnosed between 2003 and 2011 were evaluated for GRP78 expression by immunohistochemistry...

This work investigated the role of paired box 2 (PAX2) in endometrial cancer and its epigenetic regulation mechanism. Endometrial cancer tissues and cell lines exhibited increased PAX2 expression compared with hyperplasia, normal endometrium and endometrial epithelial cells. Knock-down of PAX2 resulted in reduced cell viability, invasion and migration, and PAX2 overexpression caused the opposite effects. Increased methylation of the PAX2 promoter was observed in both cancer tissues and cell lines and was positively correlated with PAX2 expression...

Endometrial tissue is under a strong influence of sex hormones. These hormones are considered as developmental factors of endometrial hyperplasia and endometrial cancer. We examined the influence of gonadotropins (follicle-stimulating and luteinizing hormone) and sex hormones (estradiol, progesterone) on oxidant/antioxidant parameters in blood and endometrial tissue of women with complex endometrial hyperplasia. In blood, superoxide dismutase activity was significantly higher in luteal phase and postmenopause compared to the follicular phase...

Two 54-year-old women developed abdominal cramps and vaginal hemorrhage as a result of endometrial hyperplasia during treatment with a hop-containing phytotherapeutic product (MenoCool(®)) for post-menopausal complaints. The women used the hop-containing phytotherapeutic product (418 mg of hop per tablet) twice daily (1 and 0.5 tablets by both patient A and B). Patient A developed abdominal cramps and vaginal hemorrhage after 2 months of use. After gynecological examination, she was diagnosed with endometrial hyperplasia...

Ovarian hyperthecosis, a source of estrogen, may occur in postmenopausal women. In this study, we evaluated the possible association of ovarian hyperthecosis with endometrial polyp, endometrial hyperplasia, and endometrioid adenocarcinoma in postmenopausal women. Our study consisted of 238 postmenopausal women: 108 with endometrioid adenocarcinoma and 130 without endometrial carcinoma. The International Federation of Gynecology and Obstetrics system was used to grade endometrioid adenocarcinoma. Within the endometrioid adenocarcinoma cases, 48 (44...

The 2014 World Health Organization (WHO) classification of uterine tumors revealed simplification of the classification by fusion of several entities and the introduction of novel entities. Among the multitude of alterations, the following are named: a simplified classification for precursor lesions of endometrial carcinoma now distinguishes between hyperplasia without atypia and atypical hyperplasia, the latter also known as endometrioid intraepithelial neoplasia (EIN). For endometrial carcinoma a differentiation is made between type 1 (endometrioid carcinoma with variants and mucinous carcinoma) and type 2 (serous and clear cell carcinoma)...

Endometritis is nowadays rare in developed countries and typically shows a subclinical or mild course; therefore, there are probably more cases of endometritis than diagnosed but they lack clinical relevance. In the fertile period of life it can be the reason for vaginal bleeding and infertility. The most common causes for non-specific endometritis are residual placental tissue after abortion or childbirth, intrauterine interventions, lesions within the uterine cavity, such as endometrial polyps, endometrial hyperplasia and neoplasms, intrauterine devices (IUD) and cervical stenosis...

Reproductive pathology of domestic guinea pigs is underreported to date. To provide a comprehensive review of uterine disease in guinea pigs, we performed a retrospective study of the pathology archives of the University of Tennessee, College of Veterinary Medicine. By histology, 13 of 37 uterine lesions in 23 animals were neoplastic; the other 24 nonneoplastic lesions included cystic endometrial hyperplasia (16 of 24), endometrial hemorrhage (3 of 24), pyometra (2 of 24), polyp (2 of 24), and mucometra (1 of 24)...

Steroidogenic acute regulatory protein (StAR) mutations are the most frequent aetiologies of congenital lipoid adrenal hyperplasia (CLAH). Phenotypes may vary, and puberty may be absent in affected individuals. To date, only two pregnancies have been described in 46,XX CLAH patients with StAR mutations; these patients exhibited ovarian steroidogenesis along with spontaneous puberty and menarche and normal menses. The patient described here presented with CLAH caused by the homozygous (unreported, 1 bp) deletion c...

Making an incorrect histopathological diagnosis of an endometrial lesion may lead to unwanted loss of fertility and therapy-associated morbidity; therefore, endometrial carcinomas need to be correctly typed and differentiated from hyperplastic precursors, benign lesions and artifacts. Typical diagnostic pitfalls are described in this article. Misdiagnosing endometrial lesions can be avoided by paying thorough attention to gross as well as microscopic features and by taking crucial differential diagnoses into consideration...

A total of 13 rabbits were treated with a subcutaneous deslorelin long-term release implant (4.7 mg) to study the effect on ovarian function and histologic features of the uterus. Seven rabbits (group 1) were implanted with a slow-release deslorelin implant before onset of puberty for 273 days as a part of a previous study. After resumption of ovarian function had been confirmed, they were implanted again at the age of 430 days. Six adult rabbits (>177 days old; group 2) were implanted with a slow-release deslorelin implant for 273 days...

Several studies have demonstrated that the combination of hysteroscopy with endometrial biopsy is more accurate in differentiating endometrial polyps from endometrial hyperplasia and cancer. However, blind biopsy not always confirms hysteroscopic findings due to high rates of inadequate or insufficient material. The objective of this clinical, prospective, and comparative study was to establish a correlation between the histological results of office-based endometrial biopsies (hysteroscopically guided and blind) with the surgical polypectomy specimens...
