BACKGROUND: Endometrial cancer is the sixth most common cancer in women worldwide and most commonly occurs after the menopause (75%) (globocan.iarc.fr). About 319,000 new cases were diagnosed worldwide in 2012. Endometrial cancer is commonly considered as a potentially 'curable cancer,' as approximately 75% of cases are diagnosed before disease has spread outside the uterus (FIGO (International Federation of Gynecology and Obstetrics) stage I). The overall five-year survival for all stages is about 86%, and, if the cancer is confined to the uterus, the five-year survival rate may increase to 97%...

Self-prescribing of sexual hormones for gender affirmation is a potentially widespread and poorly studied phenomenon that many clinicians are unaware of. The uncontrolled use of hormones poses significant health hazards, which have not been previously reported in the literature. We have collected seven clinical cases in general adult psychiatry settings (both inpatient and outpatients), describing transgender and gender non-conforming individuals' (TGNC) self-prescribing and self-administering hormones bought from the Internet without any medical consultation...

REVIEW
Ian S Fentiman
Male breast cancer (MBC) is a rare disease but, as a result of epidemiological collaborations, there is now greater clarity concerning endocrine risk factors. The significant rise in global age-standardised mean BMI in men is likely to lead to increases in incidence of maturity-onset diabetes and MBC. The metabolic changes accompanying obesity decrease androgens and sex hormone-binding globulin (SHBG), thereby increasing available oestrogens. The higher rates of MBC in North and Equatorial Africa are largely due to liver damage from endemic bilharziasis and hepatitis B causing elevated oestradiol (E2 ) levels from hepatic conversion of androgen...

Mediastinal cysts with Mullerian differentiation are characterized by oestrogen receptor and progesterone receptor positive cell linings. We treated four patients with mediastinal cysts with Mullerian differentiation. All patients were female, from 46 to 52 years old, and had BMIs greater than 26 kg/m2 . All but one patient with cough were asymptomatic. The tumours were located in the paravertebral areas around the Th-1-7 vertebrae. There was no left/right difference. All of the preoperative diagnoses were bronchial cysts...

The current issues with endocrine therapy for treatment of advanced breast cancer include balance of efficacy of therapy versus tolerability as well as hormone resistance. The efficacy of fulvestrant, a selective oestrogen receptor degrader (SERD), has been demonstrated in hormone receptor positive patients previously untreated or treated with hormonal therapy. Areas covered: This article discusses the journey of fulvestrant licensing, its efficacy in combination with other endocrine therapies and the future role it may have within breast cancer treatment...

Conjugated oestrogen is one of the more affordable secondary hormonal options available for castrate-resistant prostate cancer (CRPC) in Jamaica. The present study was conducted to examine the disease response in Jamaican men with CRPC treated with conjugated oestrogen. This study retrospectively reviewed the medical notes of patients who attended the urologic clinic of the University Hospital of the West Indies from 1 January 2009 to 31 December 2013 and a private urology clinic from 2 November 2005 to 3 June 2015 to identify patients diagnosed with CRPC treated with conjugated oestrogen (Premarin ®) as secondary therapy...

OBJECTIVE: To formulate clinical consensus recommendations on bone health assessment and management of women with oestrogen receptor-positive early breast cancer receiving endocrine therapy. METHODS: Representatives appointed by relevant Australian Medical Societies used a systematic approach for adaptation of guidelines (ADAPTE) to derive an evidence-informed position statement addressing five key questions. RESULTS: Women receiving adjuvant aromatase inhibitors and the subset of premenopausal woman on tamoxifen have accelerated bone loss and increased fracture risk...

Sensory responses to courtship signals can be altered by reproductive hormones. In seasonally-breeding female songbirds, for example, sound-induced immediate early gene expression in the auditory pathway is selective for male song over behaviourally irrelevant sounds only when plasma estradiol reaches breeding-like levels. This selectivity has been hypothesized to be mediated by release of monoaminergic neuromodulators in the auditory pathway. We previously showed that in oestrogen-primed female white-throated sparrows, exposure to male song induced dopamine and serotonin release in auditory regions...

Identification of patients at risk for fragility fractures is the first important step in the management of osteoporosis. Bisphosphonates have been the mainstay of treatment for decades, whereas denosumab and selective oestrogen receptor modulators are other available licensed antiresorptive drugs. Currently teriparatide is the only approved anabolic agent in Europe, while abaloparatide and romosozumab are awaiting approval and might be available in the near future. For bisphosphonates, current guidance suggests an initial treatment course of 3-5 years and more prolonged treatment should be pursued in patients with higher fracture risk...

Endometrial cancer is one of the most common gynaecological cancers in developed countries. Its incidence has increased 20% over the last decade and the death rate has increased >100% over the past two decades. Current models for prediction of prognosis and treatment response are suboptimal, and as such biomarkers to support clinical decision-making and contribute to individualised treatment are needed. In this study, we show that the E3-ubiquitin ligase PIR2/RNF144B is a potential targetable biomarker in endometrial cancer...

Parabens are used as antimicrobial preservative agent in many commercial products including cosmetics and pharmaceuticals. Weak oestrogenic and antiandrogenic activities have been attributed to parabens in in vitro and in vivo studies. In this study, human spermatozoa were exposed to different concentrations of an equimolar paraben mixture containing methyl, ethyl, propyl and butylparaben as well as to methylparaben alone at a concentration that is typical of commercially available vaginal lubricants. The induction of oxidative stress and DNA damage was then assessed at different time points...

Breast cancer (BC) is a heterogeneous disease that varies in presentation, morphological features, behaviour and response to therapy. High throughput molecular profiling studies have revolutionised our understanding of BC heterogeneity and demonstrated that molecular portraits of tumours are not only variable between tumours but also within individual tumours. Current evidence indicates that spatial and temporal intra-tumour heterogeneity of BC exists at levels beyond common anticipations. Intra-tumoural heterogeneity poses critical challenges in the diagnosis, prediction of behaviour and management of BC...

OBJECTIVE: A prolonged QTc (LQT) is a surrogate for the risk of torsade de pointes (TdP). QTc interval duration is influenced by sex hormones: oestradiol prolongs and testosterone shortens QTc. Drugs used in the treatment of breast cancer have divergent effects on hormonal status. METHODS: We performed a disproportionality analysis using the European database of suspected adverse drug reaction (ADR) reports to evaluate the reporting OR (ROR χ2 ) of LQT, TdP and ventricular arrhythmias associated with selective oestrogen receptor modulators (SERMs: tamoxifen and toremifene) as opposed to aromatase inhibitors (AIs: anastrozole, exemestane and letrozole)...

Drug discovery is a long, expensive and risky process. Evaluating drugs that have already been proved safe for use in humans and testing them for a new indication greatly reduces the time and monetary costs involved in finding treatments for life-threatening conditions. Here tamoxifen, a drug that is used for the treatment of breast cancer, is investigated in a mouse model of Duchenne muscular dystrophy. Tamoxifen was efficacious in countering the symptoms of the disease without affecting the underlying genetic cause...

Genital chronic graft-versus-host disease (GVHD) in women posthaematopoietic cell transplantation may cause vaginal mucosal sclerosis. Human papillomavirus (HPV) reactivation, also common post-transplantation, limits local immunosuppressive, but not oestrogen treatment. A 36-year-old nulliparous woman developed coincidental genital chronic GVHD and HPV 22 months after transplant for aplastic anaemia. Topical immunosuppression for GVHD led to an eruption of warts successfully treated with laser surgery and cone biopsy...

Triple-negative breast cancer (TNBC) tumours that lack expression of oestrogen, and progesterone receptors, and do not overexpress the HER2 receptor represent the most aggressive breast cancer subtype, which is characterised by the resistance to therapy in frequently relapsing tumours and a high rate of patient mortality. This is likely due to the resistance of slowly proliferating tumour-initiating cells (TICs), and understanding molecular mechanisms that control TICs behaviour is crucial for the development of effective therapeutic approaches...

Objective: A comprehensive survey was conducted courtesy of the Turkish Turner study group to evaluate the shortcomings of clinical care in patients with Turner syndrome (TS) in Turkey. Methods: A structured questionnaire prepared by the Turner study group in Turkey, which covers relevant aspects of the care of patients with TS, was sent to all pediatric endocrinology centers. Results: Eighteen centers (41%) returned the questionnaire. In the majority of the centers, diagnostic genetic testing, screening for Y chromosomal material, protocols regarding the timing and posology of growth hormone (GH) and estrogen, thrombophilia screening, fertility information, and screening for glucose intolerance, thyroid, and coeliac diseases in patients with TS were in line with the current consensus...

Variance in spatial abilities are thought to be determined by in utero levels of testosterone and oestrogen, measurable in adults by the length ratio of the 2nd and 4th digit (2D:4D). We confirmed the relationship between 2D:4D and spatial performance using rats in two different tasks (paired-associate task and watermaze) and replicated this in humans. We further clarified anatomical and functional brain correlates of the association between 2D:4D and spatial performance in humans.
