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...

Introduction: Ectopic thyroid is a rare entity, resulting from developmental defects at early stages of thyroid embriogenesis. It’s prevalence is 1/100 000–300 000 in general population and 1/4000–8000 in patients with thyroid disease. This condition is more common in females, in Asians and may occur at any age, although it’s most common at younger ages. The most frequent location of ectopic thyroid tissue is at the base of the tongue. In 70–75% of cas...

Introduction: MEN1 is inherited as an autosomal dominant trait, with a prevalence of 2–20/100 000 in the general population. It is characterized by tumors envolving the parathyroid glands, the endocrine pancreas and the pituitary. Other tumors are more rarely associated: adrenal adenomas, carcinoid tumors, pheocromocytomas, angiofibromas, lipomas, collagenomas and meningiomas. The presence of two or more of MEN1 associated tumors is diagnostic of the syndrome.<p class...

Background: Insulinomas are rare neuroendocrine tumours (4 cases/million patients per year), representing an important cause of hyperinsulinemia. Usually are benign and sporadic, but can be part of multiple endocrine neoplasias. To establish the diagnosis it is essential to document inappropriately high levels of insulin during episodes of hypoglycaemia.Aim: Retrospective analysis of the clinical files of the patients followed in our department since Jan...

Graves’ disease is characterized by the occurrence of antibodies against thyroid-stimulating hormone (TSH) receptor that stimulate the gland to produce T4 and T3. It can be accompanied by an infiltrative orbitopathy and oftalmopathy. Another seldom- regognized feature of this disease is thymic hyperplasia.The authors report the case of a 22-year-old woman with Graves’ disease (TSH receptor antibodies 178 U/l) with exuberant oftalmopathy and an ...
