Exaggerated Flare Up Effect Of GnRH Agonist Resulting In Multifollicular D...Mohamed Walaa El Deeb
1) A 25-year-old woman with PCOS and infertility underwent a long protocol with the GnRH agonist triptorelin. Surprisingly during monitoring, she had high estrogen levels and follicles ranging 14-23mm, nearly causing OHSS.

Tamoxifen is used for prophylaxis of breast cancer in high-risk women. It works by competing with estrogen for binding to estrogen receptors in breast tissue, thereby blocking the normal stimulatory effects of estrogen on breast growth. Some breast tumors may regress with tamoxifen treatment due to this antagonism of estrogen receptors in breast cells. The drug is administered orally where it undergoes extensive metabolism by the CYP450 system.
Hormone therapy in postmenopausal womenMayuriSimon
This document discusses hormone replacement therapy (HRT) for postmenopausal women. It defines menopause and describes the hormonal changes that occur. It explains that HRT can help relieve menopausal symptoms, prevent osteoporosis, and maintain quality of life. However, HRT also carries some risks like breast and endometrial cancer if not administered properly. The document discusses the various HRT preparations available, recommended durations of use, and the importance of monitoring women receiving HRT.
The document discusses the hypothalamic-pituitary-gonadal axis and its role in regulating the female reproductive cycle and secretion of sex hormones including estrogens and progesterone. It provides details on the types of estrogens and progestins, their mechanisms of action, therapeutic uses in hormone replacement therapy, contraception, and management of menopausal symptoms. Adverse effects and drug interactions are also summarized.
1. Hormonal contraceptives work by intercepting the birth process through mechanisms like inhibiting ovulation, thickening cervical mucus, or preventing implantation of a fertilized egg.
2. Common types include combined oral contraceptives containing estrogen and progestin, progestin-only pills, injectables, implants, and intrauterine devices.
3. Combined oral contraceptives primarily work by inhibiting the release of hormones needed for ovulation. Progestin-only methods thin the uterine lining to prevent implantation. Side effects are usually mild but can include changes to bleeding patterns or mood.
Enlargement of the male breast tissue.
Greek word Gynae-women
mastos-breast
Presence of >2cm of palpable,firm,sub areolar gland and ductal breast tissue.
A benign enlargement of the male breast resulting from a proliferation of the glandular component of the Brest.
It may cause due to the changes in endocrine system, presence of chronic diseases, certain metabolic dysfunctions.
Gynaecomastia is the enlargement of male breast tissue. It’s a common, benign (not cancer) condition that mainly affects teenage boys and older men, but it can affect men at any age.
Phytoestrogens are plant-derived compounds that are similar in structure to estrogen. They are found in various foods like soy, flaxseed, and sesame seed. Phytoestrogens bind to estrogen receptors in the body and may help reduce menopause symptoms like hot flashes.

Cell Therapy Expansion and Challenges in Autoimmune DiseaseHealth Advances
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.
