Background: Schmidt’s syndrome, also known as poliglandular autoimmune syndrome type 2, is a rare disease that has a prevalence between 1.5-4.5 cases per 100 000 inhabitants. The diagnosis consists in the concomitant presentation of Addison disease, autoimmune thyroid disease and other autoimmune endocrinological conditions. The aim of this paper is to describe a case of Schmidt’s syndrome in the peruvian context and to analyze the difficulties in the diagnosis. Clinical case: We present the case of a 43-year-old woman that presents to the emergency room with headache, nausea, vomits and a “syncope episode”...

Uterine leiomyoma is the most common benign tumour in women, and an appropriate animal model for leiomyoma would be useful for exploring new therapeutic strategies. Therefore, we have been challenged to develop a new simple mouse model for human leiomyoma. Leiomyoma tissues were harvested from myomas resected by different surgical procedures with or without gonadotropin-releasing hormone agonist (GnRHa) treatment and were subcutaneously implanted into BALB/c nude mice with an estradiol/progesterone-releasing pellet...

Neonates can be exposed to bisphenol A (BPA) through placenta and milk, and BPA is associated with disorders such as precocious puberty and obesity. We evaluated the effects of BPA exposure during breastfeeding on the biochemical and endocrine profiles in young and adult rat progeny. From postnatal day (PND) 3 to 15 dams were divided into low-dose BPA treatment [50 μg/kg/day s.c. (BPA-LD)], high-dose BPA treatment [5 mg/kg/day s.c. (BPA-HD)], and Control (vehicle) groups. Milk was collected at PND15 and 21, which represents the end of exposure and 6 days after withdrawal, respectively...

Leptin (Lep) is a key factor for the regulation of food intake and energy homeostasis in mammals. To date, a number of studies have provided evidence for the existence of multiple leptin genes in teleosts, but not much information is available in fish regarding the regulation of leptin genes by sex steriods. As a first step, two leptin genes (lepa and lepb) and a leptin receptor (lepr) gene were cloned from the half-smooth tongue sole (Cynoglossus semilaevis), a representative species of the order Pleuronectiformes...

OBJECTIVE: Neurogenesis is the principal regenerative mechanism to sustain the plasticity potential in adult brains. Decreased neurogenesis parallels the cognition decline with aging, and has been suggested as a common hallmark in the progression of many neurodegeneration diseases. We previously reported that acute exposure to segesterone acetate (ST-1435; Nestorone), alone or in combination with 17β-estradiol (E2), increased human neural stem cells proliferation and survival both in vitro and in vivo...

BACKGROUND: Caudal dorsomedial hindbrain detection of hypoglycemia-associated lactoprivation regulates glucose counter-regulation in male rats. In females, estradiol (E) determines hypothalamic neuroanatomical and molecular foci of hindbrain energy sensor activation. This study investigated the hypothesis that E signal strength governs metabolic neuropeptide and counter-regulatory hormone responses to hindbrain lactoprivic stimuli in hypoglycemic female rats. METHODS: Ovariectomized animals were implanted with E-filled silastic capsules [30 (E-30) or 300 μg (E-300)/mL] to replicate plasma concentrations at estrous cycle nadir versus peak levels...

Low energy availability (LEA), and subsequent relative energy deficiency in sport (RED-S), has been observed in endurance, aesthetic, and team sport athletes, with limited data on prevalence in athletes in short-burst activities such as sprinting. We examined prevalence of signs and symptoms of LEA in elite female sprinters at the start of the training season (PRE), and at the end of a 5-month indoor training period (POST). Four of 13 female sprinters (31%) presented at PRE testing with at least one primary (amenorrhea, low BMD, low FSH, LH, or estradiol, RMR ≤ 29kcal/kg FFM, Low Energy Availability in Females Questionnaire (LEAF-Q) score ≥8) and one secondary indicator of LEA (fasting blood glucose < 4mmol/L, free triiodothyronine < 3...
