Diabetes insipidus is a disease characterized by the inability to concentrate urine. The common form is central diabetes insipidus (CDI) caused by a lack of AVP after destruction of supraoptic–paraventricular nuclei. Further investigations are needed to establish its cause.: Case reportA 38-year-old woman presented with prompt polyuria–polydipsia. She has been taking contraceptive tablets for 2 years, smoked four to five cigarettes per day....

Objectives: To evaluate the different insulin regimens and types of insulin used in our population of type 1 diabetes (DM1) patients in the last revision in our clinic.Method: A descriptive study was carried out in our population of 535 DM1 patients. They had their initial diagnosis between 1967 and 2014.Results: In our population, 47.3% were women and 52.3% were men. The mean age of our patients was 33.8 years (S.D....

Thyrotropin-secreting pituitary tumors are <1% of pituitary adenomas. Clinical manifestations are similar to other forms of hyperthyroidism. Most of them are diagnosed as macroadenoma (microadenomas <10%).Case 1: A 48 years old woman with menopause presented 6 years ago, consulting in 2009 for weight loss and palpitations. She had elastic goiter and distal tremor. Blood test: TSH 8.66 μUI/ml (0.2–4.2), FT4 4.7 ng/dl (0.7&#150...

Introduction: After menopause, an abrupt drop in estrogen levels happens, while ovary androgens secretion declines gradually with aging. This relative hyperandrogenism may lead to the development of hyperandrogenic symptoms. However, the development of marked hirsutism and/or symptoms/signs of virilization, make necessary a detailed study in order to rule out tumorous cause (from adrenal glands or ovaries).Case report: 58 years old woman with progressive...

Introduction: Oncocytomas are tumours composed by oncocytes, cells with granular and eosinophilic cytoplasm filled with mitochondria. It is a neoplasm that can arise in several organs (more commonly described in the kidney, salivary gland and thyroid). Oncocytoma arising in the adrenal gland is a rare finding. Most of them are benign and non-functioning and are detected incidentally. However, functional adrenal oncocytomas presenting as Cushing’s syndrome and phaeochromoc...

Introduction: Cushing’s syndrome (CS) due to macronodular adrenal hyperplasia ACTH-independent (MAHAI) is rare. Regulation of cortisol secretion by G-protein-coupled receptors (GPCRs) aberrantly expressed is frequently found in MAHAI. Various aberrant receptors have been reported, mostly: GIP, vasopressin, beta-adrenergic, LH/hCG and serotonin.Case report: 61 years old woman. Medical history: type 2 diabetes, hypertension, obesity, dyslipidaemia and...

Introduction: New long-acting insulin analogues (insulin degludec –ID- and insulin glargine 300 U/ml –IG300-) have proved, in clinical trials, that improve metabolic control with lower hypoglycemia rate in T2D.Objective: To assess characteristics of T2D patients who were given ID and IG300 and to evaluate their effect on metabolic control, weight and insulin dose.Material and methods: We studied T2D patients whose treatme...
