It also has a significant, non-con- traceptive impact on women’s body. These drugs can be used in various endocrinological disorders, because of their ability to reduce the level of male hormones. The aim of our study is to establish a correlation between taking different types of anti-androgenic drugs and intensity of hirsutism, acne, menstrual pain intensity and sexuality . Material and methods: 570 women in childbearing age that had been using oral contraception for at least three months took part in our research. We examined women and asked them about quality of life, health, direct causes and effects of that treatment, intensity of acne and menstrual pain before and after. Our research group has been divided according to the type of gestagen contained in the contraceptive pill: dienogest, cyproterone, chlormadynone and drospirenone. Ad- ditionally, the control group consisted of women taking oral contraceptives without antiandrogenic component. Results: The mean age of the studied group was 23 years ± 3.23. 225 of 570 women complained of hirsutism.

  • Prescribing Support Information GONADORELIN ANALOGUES To
    Pending CCG approval Prescribing Support Information GONADORELIN ANALOGUES to achieve feminisation or masculinisation following assessment and diagnosis of Gender Incongruence at the NHS commissioned Cheshire and Merseyside Gender Identity Service AMBER patient retained by specialist Your patient has been identified as being suitable to receive a gonadorelin analogue in accordance with the indications detailed below. They have been started on treatment and have been reviewed to assess the efficacy and adverse effects of the treatment by the specialist team. Prescribing has been retained by the specialist team for the first 6-12 months until stabilisation of the dose and monitoring requirements has been achieved. Triptorelin is the Pan Mersey first line choice. Gonadorelin analogue treatment will continue until gonadectomy. Gonadorelin analogue treatment has been considered as appropriate for prescribing in primary care and the information contained in this document has been provided to support you to prescribe the medicine for your patient in the community. Your patient’s dose is now stable and is detailed in the attached clinic letter. There has been a significant amount of experience in the treatment of gender incongruence over the last 40 years, using several well-established hormonal protocols, and the available evidence demonstrates that, for carefully selected patients, hormone therapy is a safe and effective means of alleviating the potentially debilitating condition of gender dysphoria.1.2 Although these medicines are not licensed for the treatment of gender incongruence, they are medicines with which GPs may be familiar. Your patient will remain under the care of a specialist team within Cheshire and Merseyside Gender Identity Collaborative (CMAGIC) whilst receiving this medicine and will be able to be fast tracked back into the gender service if there are any issues.

The current HMMC decision recommends triptorelin as Decapeptyl SR® injection as the gonadorelin analogue of choice within licensed indications (which include endometriosis) link to decision. A request was made by ENHT to use nafarelin nasal spray as an alternative to triptorelin intramuscular injection during the COVID-19 pandemic. The hospital would provide initial 1 month supply, then GPs would continue for further 5 months as an alternative to the patient attending for further clinic appointments for administration of triptorelin. Previously at ENHT, triptorelin was the only gonadorelin analogue on formulary for gynaecological indications. At WHHT buserelin nasal spray 150mcg/dose is RED (hospital only) for infertility & endometriosis indications. Nafarelin nasal spray 2mg/ml is licensed for: . The hormonal management of endometriosis, including pain relief and reduction of endometriotic lesions. Use in controlled ovarian stimulation programmes prior to in-vitro fertilisation, under the supervision of an infertility specialist. Use of nafarelin in endometriosis aims to induce chronic pituitary desensitisation, which gives a menopause-like state maintained over many months.

  • Prostate Cancer and Sexual Function
    Prostate Cancer and Prostatic Diseases (1998) 1, 179 ±184 ß 1998 Stockton Press All rights reserved 1365±7852/98 $12.00 http://www.stockton-press.co.uk/pc Review Prostate cancer and sexual function RS Kirby,1 A Watson2 and DWW Newling3 1St. George's Hospital, London, UK; 2Watson Biomedical, Maidstone, UK; and 3Academisch Ziekenhuis der Vrije Universiteit, Amsterdam, The Netherlands Erectile dysfunction is a condition affecting 1 in every 10 men. Although its occurrence is related to ageing, illness and its necessary therapy can play a major role. Prostate cancer can lead to erectile dysfunction both psychologically through depression and emotional distress, and physically through therapy for the disease. An international quality of life survey involving 401 patients with prostate cancer was conducted. The objectives of the study were to investigate the patients' understanding of the treatment options they received, to explore the importance of the patient±doctor communication in the treatment of prostate cancer and to see what effect treatment had on patient's sexual function. One of the main ®ndings of the survey was that too little counselling or information on treatment options and their effects on sexual function was provided to patients. Patients themselves felt that psychosexual counselling, in particular, would be helpful. In addition, therapy for prostate cancer appears to have a signi®cant impact on patients' lifestyle and also on their libido, sexual function and activity.

  • Determination of 17 Hormone Residues in Milk by Ultra-High-Performance Liquid Chromatography and Triple Quadrupole Mass Spectrom
    No. LCMSMS-065E Liquid Chromatography Mass Spectrometry Determination of 17 Hormone Residues in Milk by Ultra-High-Performance Liquid Chromatography and Triple Quadrupole No. LCMSMS-65E Mass Spectrometry This application news presents a method for the determination of 17 hormone residues in milk using Shimadzu Ultra-High-Performance Liquid Chromatograph (UHPLC) LC-30A and Triple Quadrupole Mass Spectrometer LCMS- 8040. After sample pretreatment, the compounds in the milk matrix were separated using UPLC LC-30A and analyzed via Triple Quadrupole Mass Spectrometer LCMS-8040. All 17 hormones displayed good linearity within their respective concentration range, with correlation coefficient in the range of 0.9974 and 0.9999. The RSD% of retention time and peak area of 17 hormones at the low-, mid- and high- concentrations were in the range of 0.0102-0.161% and 0.563-6.55% respectively, indicating good instrument precision. Method validation was conducted and the matrix spike recovery of milk ranged between 61.00-110.9%. The limit of quantitation was 0.14-0.975 g/kg, and it meets the requirement for detection of hormones in milk.

Upon administration, tanibirumab specifically binds to VEGFR2, thereby preventing the binding of its ligand VEGF. This may result in the inhibition of tumor angiogenesis and a decrease in tumor nutrient supply. VEGFR2 is a pro-angiogenic growth factor receptor tyrosine kinase expressed by endothelial cells, while VEGF is overexpressed in many tumors and is correlated to tumor progression.
