Endocrine pathology is the subspecialty of diagnostic pathology which deals with the diagnosis and characterisation of neoplastic and non-neoplastic diseases of the endocrine system. This relatively young subspecialty was initially focused mainly on thyroid and parathyroid pathology, with some participants also involved in studies of the pituitary, the endocrine pancreas, and the adrenal glands. However, the endocrine system involves much more than these traditional endocrine organs and the discipline has grown to encompass lesions of the dispersed neuroendocrine cells, including neuroendocrine tumours (NETs) of the lungs, gastrointestinal tract, thymus, breast and prostate, as well as paraganglia throughout the body, not just in the adrenals...

Cytology in China developed from nothing and underwent a long journey from gynecologic cytology to that of all organs, laying a solid foundation for new developments in the 21st century. Thyroid fine-needle aspiration (FNA) was primarily developed in an endocrinology department and then in the clinical laboratory department or pathology department in the 1970-80s. Wrights staining is popular in endocrine and clinical laboratory departments, while hematoxylin and eosin staining is common in pathology. Liquid based cytology is not common in thyroid FNA cytology, while BRAFV600E mutation analysis has been the most popular molecular test...

Polycystic ovary syndrome (PCOS)is a gynecological endocrine disorder which is associated with systemic inflammatory status inducing red blood cells (RBC) membrane alterations related to insulin resistance and testosterone levels which could be greatly improved by myo-inositol (MYO) uptake. In this study we aim to evaluate the effect of MYO in reducing oxidative-related alterations through in vitro study on PCOS RBC. Blood samples from two groups of volunteers, control group (CG, n = 12) and PCOS patient group (PG, n = 12), were analyzed for band 3 tyrosine phosphorylation (Tyr-P), high molecular weight aggregate (HMWA), IgG in RBC membranes, and glutathione (GSH) in cytosol, following O/N incubation in the presence or absence of MYO...

Chronic stress induces endocrine disturbance, which contributes to the development of polycystic ovary syndrome (PCOS), a condition that remains a challenge for clinicians to cope with. The present study investigated the effect of Xiao-Yao-San (XYS), a traditional Chinese medicine formula used for treatment of gynecological disease, on the chronic stress-induced polycystic ovary and its underlying mechanism. Female Sprague-Dwaley rats underwent a 3 weeks chronic unpredictable mild stress (CUMS) procedure to establish the PCOS model, followed by 4 weeks treatment with XYS (0...

STUDY QUESTION: What is the physiological function of Yes-associated protein-1 (Yap1), a susceptibility gene for polycystic ovary syndrome (PCOS), in ovarian granulosa cells (GCs)? SUMMARY ANSWER: Physiologically, steroid sex hormones stimulate follicle growth by activating YAP1; however, the preovulatory inhibition of YAP1 activity in GCs is a prerequisite of LH actions. WHAT IS KNOWN ALREADY: PCOS is a common gynecologic and endocrine disease with multiple short and long-term consequences...

Most prior studies of primary diagnosis in surgical pathology using whole slide imaging (WSI) versus microscopy have focused on specific organ systems or included relatively few cases. The objective of this study was to demonstrate that WSI is noninferior to microscopy for primary diagnosis in surgical pathology. A blinded randomized noninferiority study was conducted across the entire range of surgical pathology cases (biopsies and resections, including hematoxylin and eosin, immunohistochemistry, and special stains) from 4 institutions using the original sign-out diagnosis (baseline diagnosis) as the reference standard...

REVIEW

Hippocrates attributed women's high emotionality - hysteria - to a 'wandering womb'. Although hysteria diagnoses were abandoned along with the notion that displaced wombs cause emotional disturbance, recent research suggests that elevated levels of oxytocin occur in both bipolar disorder and endometriosis, a gynecological condition involving migration of endometrial tissue beyond the uterus. We propose and evaluate the hypothesis that elevated oxytocinergic system activity jointly contributes to bipolar disorder and endometriosis...

A number of paraneoplastic syndromes have been described with gynecological cancers. These syndromes are induced by substances secreted by the tumor or by an immune response triggered by the cancer. Each system of the human body can be affected by different syndromes. Indeed, paraneoplastic syndromes occurring from tumors of the gynecologic tract were found to involve the nervous, ophthalmologic, dermatologic, rheumatologic, endocrine, hematologic and renal systems. These syndromes can manifest before, at the time, or after the diagnosis of cancer...

A 31-year-old lady, diagnosed to have premature ovarian failure in the gynecology clinic, was referred for endocrine assessment because of an abnormal thyroid function test. Clinical examination revealed hypotension, and fungal skin infection under her atrophic breasts. Thyroid stimulating hormone (TSH) level was very high. Assessment of the suprarenal function revealed evidence of Addison's disease. Polyglandular autoimmune dysfunction was diagnosed. She was treated with prednisone, fludrocortisone, and levothyroxine with significant improvement of her general condition and blood pressure...

17β-estradiol (E2) can contribute to the progression of epithelial ovarian cancer (EOC). Although the majority of patients with EOC are postmenopausal woman, when de novo estrogen production in the ovary has ceased, ovarian cancer cells remain exposed to estrogens synthesized locally in the cancer cells from inactive sulfonated steroid hormone precursors-such as estrone sulfate taken up from the circulation via the sulfatase pathway. An abundance of the estrogen-modifying enzymes, including estrogen-activating steroid sulfatase (STS) and estrogen-inactivating estrogen-sulfotransferase (SULT1E1), is important for providing active estrogen to EOC cells...

Lynch syndrome (LS) is a genetic condition conferring an elevated risk of gastrointestinal, gynecologic and other malignancies, often before the age of 50. Current guidelines recommend prophylactic gynecologic surgery to manage inherited cancers for female mutation carriers. Data is lacking on women's quality of life following surgery. In this pilot study, we explored how women described their quality of life post-prophylactic gynecologic surgery and the factors that affected post-surgery experiences. A qualitative interview study was the chosen design...

Personalized healthcare relies on accurate companion diagnostic assays that enable the most appropriate treatment decision for cancer patients. Extensive assay validation prior to use in a clinical setting is essential for providing a reliable test result. This poses a challenge for low prevalence mutations with limited availability of appropriate clinical samples harboring the mutation. To enable prospective screening for the low prevalence AKT1 E17K mutation, we have developed and validated a competitive allele-specific TaqMan® PCR (castPCR™) assay for mutation detection in formalin-fixed paraffin-embedded (FFPE) tumor tissue...

Ovarian cancer is the seventh most common cancer in women and the most lethal gynecological cancer, causing over 151,000 deaths worldwide each year. Dysregulated production of endocrine hormones, known to have pluripotent effects on cell function through the activation of receptor signaling pathways, is believed to be a high-risk factor for ovarian cancer. An increasing body of evidence suggests that endocrine G protein-coupled receptors (GPCRs) are involved in the progression and metastasis of ovarian neoplasms...

Polycystic ovarian syndrome (PCOS) is the most common endocrine disorder in gynecology. In PCOS patients vascularization parameters are altered. Transvaginal hydrolaparoscopy (THL) is a mini-invasive approach for ovarian drilling in PCOS patients. In this study, we assessed the effect of ovarian drilling using THL on ovarian volume (OV) and vascularization index (VI) using 3D power Doppler ultrasonography in CC-resistant PCOS patients. A case-control study on 123 CC-resistant PCOS women who underwent THL ovarian drilling was performed...

OBJECTIVE: To study the contribution of hormonal cytology in contemporary disturbances of fertility. DESIGN: Over a 10-year period (2006-2015), 6,688 vaginal fornix cytologies of 2,350 patients were investigated. For a more detailed analysis, a 3-year period from 2013 to 2015 was chosen. Four hundred and fifty-two patients were investigated, many of them several times and for a period longer than the 3 years analyzed. RESULTS: The main disorders examined and treated via a gentle hormonal medication support and life style corrections by a pediatric gynecologist were: pubertas praecox - thelarche praecox and early menarche; dysfunctional juvenile metrorrhagia; central and peripheral endocrine disorders; eating disorders - anorexia mentalis and bulimia; obesity; excessive sport activities; autoimmune disorders, and others...
