A 36-year-old woman in follow-up due to early ovarian failure of idiopathic origin. No family history of interest. History of menarche at 12 years of age with regular menses until 18 years of age, when it begins with amenorrheic spells lasting up to 8 months. Laboratory tests revealed hypergonadotropic hypogonadism with negative ovarian autoantibodies, normal karyotype, and gynecological ultrasound showing a normal-looking uterus with slight bilateral ovarian atrophy. Negative...

Introduction: Demand for health care for transsexual people has increased exponentially in last years, especially among adolescents and young adults. Gender-affirming hormones (GAHs) are initiated to accommodate secondary sexual characteristics to the desired sex. Published studies about metabolic repercussion of GAHs are heterogeneous and report diverse results. Our objective is to evaluate the effect of GAHs on cardiovascular risk factors in transsexual population treated in...

Introduction: Adrenal incidentalomas are a frequent finding (1.4-7.3% on abdominal CT) and increasingly common with age, obesity, diabetes and hypertension. When approaching adrenal masses, clinicians should exclude malignancy and hormonal hypersecretion. Black adrenal adenomas (BAA), first reported in 1938, are rare benign adrenocortical tumours with black/brown appearance, containing lipofuscin. Most are non-functional, rarely inducing hypercortisolism. We present a case of ...

Introduction and objectives: The inhalation of tobacco smoke leads to an acute increase in cortisol, ACTH and GH concentration, both in chronic smokers as in non-smokers. However, most studies have failed to demonstrate differences between both groups in basal levels of these hormones in plasma or urine. Additionally, cholinergic pathways have been shown to play an inhibitory role in ACTH secretion in non-smokers. UFC and circulating levels of cortisol, ACTH and GH were evalua...

Introductions: Alterations of the somatotrophic and hypothalamic–pituitary–adrenal (HPA) axes occur frequently in patients with poorly controlled DM-1. These disorders could be related to abnormalities in the cholinergic tone regulating both hormonal axes.Subjects and Methods: UFC (urinary free cortisol) on 24 h urine samples and the effects of placebo and pyridostigmine on ACTH, cortisol, GH and glucose circulating levels were studied in 16 yo...

Introduction and Objectives: In patients with poorly controlled DM-1, the frequently observed alterations of somatotrophic axis seem to be related to abnormalities in the hypothalamic cholinergic tone regulating this axis. The effects of cholinergic stimulation on GH responses to GHRH were evaluated in patients with poorly controlled DM-1 and the relationship of these responses to metabolic control and kidney function tests.Subjects and Methods: Microalb...

Cushing’s Syndrome (CS) is an uncommon disease worldwide, being characterized by an increased production of glucocorticoids, and if left untreated can lead to serious consequences and women with CS rarely get pregnant. The aim of our work is to make a systematic review of the cases of pregnancy in patients with previously diagnosed CS, being performed an extensive research of the Medline and Web of Knowledge databases, and add three new cases observed in our institution. ...

Background: Catecholamine-secreting tumors that arise from chromaffin cells of the adrenal medulla and the sympathetic ganglia are respectively referred to as pheochromocytomas and paragangliomas. The classic triad of symptoms in patients with pheochromocytoma (PHEO)consists of episodic headache, sweating, and tachycardia. Approximately one-half have paroxysmal hypertension; the rest have either primary hypertension or normal blood pressure. Clinicians should always consider P...

Introduction: Androgen secreting neoplasms of the ovary are rare and usually show autonomous secretion. Steroid cell tumors of the ovary represent less than 0.1% of all ovarian tumors and are a subgroup of sex cord-stromal tumors. In most cases, patients present with androgenic clinical features.Case report: A 58-year-old woman complained of rapid onset of androgenic alopecia, excessive hirsutism and clitoromegaly. Endocrine assessment showed high levels...

Introduction: Central and Peripheral Diabetes Insipidus are both rare conditions. Combined they may result in serious hypernatremia and water deficit that may pose a therapeutic challenge.Case report: MHBCR, a caucasian female aged 52, was admitted to the Endocrine Department because of serious hypernatremia. A previous diagnosis of pituitary failure and central diabetes insipidus was established 4 years before, after pituitary surgery for a non-secretin...
