Alternative RNA splicing results in the translation of diverse protein products arising from a common nucleotide sequence. These alternative protein products are often functional and can have widely divergent actions from the canonical protein. Studies in humans and other vertebrate animals have demonstrated that alternative splicing events increase with advanced age, sometimes resulting in pathological consequences. Menopause represents a critical transition for women, where the beneficial effects of estrogens are no longer evident; therefore, factors underlying increased pathological conditions in women are confounded by the dual factors of aging and declining estrogens...

This review is focused on the ovarian cancer risk reduction management in BRCA mutation carriers and is intended to assist with clinical decision-making. Obviously, treatment decisions must be based on the available evidence. Despite risk-reducing salpingo-oophorectomy is firmly recommended, several separate questions can be raised to address the variety of intense controversy of this approach. A special emphasis lies in the effective preventive surgical measure against ovarian cancer risk, in an attempt to detect the optimal timing and mitigate the impact on patients...

Congenital combined pituitary hormone deficiency (CPHD) may present with cholestasis in the neonate or during early infancy. However, its precise mechanism is unknown. A 3-mo-old boy presented with cryptorchidism and hypoplastic scrotum after birth. Neonatal jaundice was noted but temporarily improved with phototherapy. Jaundice recurred at 2 mo of age. Elevated direct bilirubin (D-Bil) and liver dysfunction were found but cholangiography showed no signs of biliary atresia (BA). Liver biopsy findings showed giant cell formation of hepatocytes with hypoplastic bile ducts...

Perimenopause marks a period of increased migraine prevalence in women and many women also report troublesome vasomotor symptoms. Migraine is affected by fluctuating estrogen levels with evidence to support estrogen 'withdrawal' as a trigger of menstrual attacks of migraine without aura, while high estrogen levels can trigger migraine aura. Maintaining a stable estrogen environment with estrogen replacement can benefit estrogen-withdrawal migraine particularly in women who would also benefit from relief of vasomotor symptoms...

Estrogens are commonly used in gynecologic area, such as oral contraception, hormone replacement therapy, and in vitro fertilization-embryo transfer. Although estrogen is a common cause of acute drug-induced pancreatitis, there has been paucity of report in Korea. Clinical course of estrogen-induced acute pancreatitis is usually mild to moderate, but fetal case can occur. In addition, there can be a latency from the first administration to the symptom. Therefore, physicians should consider the possibility of the disease when a woman taking estrogen or previous history of taking estrogen presents with acute abdominal pain...

Treatment of primary adrenal insufficiency (PAI) requires lifelong hormone replacement with glucocorticoids (GCs) and mineralocorticoids. Impaired quality of life and increased standardized mortality ratio in these patients emphasize the importance of tailoring therapy to individual needs. Role of education is paramount in improving patient compliance and in anticipating and preventing adrenal crises. Although discovery of synthetic GCs was a major breakthrough in treatment of patients with this life-threatening condition, management of PAI continues to be challenging...

We present a case of severe calciphylaxis in both thighs and calves in a patient with end-stage renal disease and advanced secondary hyperparathyroidism with successful outcome after modified therapeutic approach. The cause of calciphylaxis is multifactorial. In our case, not only severe hyperparathyroidism and mediocalcinosis, but also medication (warfarin, calcium and active vitamin D) was involved. Because the initial conservative therapy was not successful, we indicated parathyroidectomy. However, we were not able to localize parathyroid glands and we contraindicated bilateral neck exploration due to the patient's critical status...

BACKGROUND: No clear guideline exists for the management of female hormone therapy in the perioperative period. Besides oral contraceptives (OCPs), hormone medications have been prescribed to treat cancer, osteoporosis, and menopausal symptoms. Since the introduction of OCPs in the 1960s, the thromboembolic risk associated with these medications has been studied and alterations have been made in the hormone content. The continuation of hormone therapy in the perioperative period and its possible interactions with commonly used anesthetic agents are important information for all perioperative health care providers...

BACKGROUND AND AIM: Subclinical hypothyroidism has been linked to increased risk of atherosclerotic disease. Soluble CD40 ligand (sCD40L), mainly derived from activated platelets, and the lipid peroxidation product 8-iso-prostaglandin F2α (8-iso-PGF2α) are known to play a relevant pathophysiological role in atherogenesis. In this study, we analyzed the relationship between thyroid hormones and circulating levels of sCD40L and 8-iso-PGF2α in patient with recent-onset post-thyroidectomy subclinical hypothyroidism under replacement therapy...

The Transcription factor BarH like homeobox 1 (BARHL1) is overexpressed in medulloblastoma and plays a role in neurogenesis. However, much about the BARHL1 regulatory networks and their functions in neurodegenerative and neoplastic disorders is not yet known. In this study, using a tissue microarray (TMA), we report for the first time that BARHL1 is downregulated in hormone-negative breast cancers and Alzheimer's disease (AD). Furthermore, using an integrative bioinformatics approach and mining knockout mouse data, we show that: (i) BARHL1 and Estrogen Receptor 1 (ESR1) may constitute a network that regulates Neurotrophin 3 (NTF3)- and Brain Derived Neurotrophic Factor (BDNF)-mediated neurogenesis and neural survival; (ii) this is probably linked to AD pathways affecting aberrant post-translational modifications including SUMOylation and ubiquitination; (iii) the BARHL1-ESR1 network possibly regulates β-amyloid metabolism and memory; and (iv) hsa-mir-18a, having common key targets in the BARHL1-ESR1 network and AD pathway, may modulate neuron death, reduce β-amyloid processing and might also be involved in hearing and cognitive decline associated with AD...

James I Raeside
The role of steroids in human medicine is well recognized, but the major contributions made by the large domestic animals as a source of material in the discovery, isolation, and determination of the structure of the steroid hormones is less well appreciated. After a brief reminder of the early efforts to obtain a reliable source of steroids for clinical use, the narrative here is to outline one example where success was ultimately achieved for estrogen replacement therapy. Whereas knowledge of the high concentrations of estrogens in urine of pregnant women and mares dates from the late 1920s, it was not until the 1940s that the latter was shown to be a practical source...
