Hypophysitis are a heterogeneous group of inflammatory lesions affecting the hypophysis. Have been described hypophysitis secondary to administration of immunomodulatory drugs such as interferon and anti-cytotoxic T lymphocyte antigen-4 antibodies (CTLA-4). Ipilimumab is an anti-CTLA-4 human monoclonal antibody that blocks the union between CTLA-4 and B7 receptor on antigen-presenting cells causing an antitumoral effect and increasing the production of autoantibodies. Hypophys...

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....

Progression of metabolic syndrome to diabetes is not easily predicted in patients with morbid obesity. We hypothesized that no insulin-resistance is more usual as we thought.Objective: Evaluate prevalence of no insulin-resistance status in patients with morbid obesity.Patients and method: The study was undertaken in 130 patients with a BMI of 53.93±6.67 kg/m2. The morbidly obese patients were divided into four group...

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: The European Society of Endocrinology Clinical Practice Guideline defines follow-up recommendations for AI based on the 1 mg overnight dexamethasone suppression test and the presence of associated comorbidities. Follow-up is not recommended for AI presenting serum cortisol levels post dexamethasone ≤1.8 μg/dl neither those presenting serum cortisol levels post dexamethasone between 1.9–5 μg/dl (defined as ‘possible autonomous cortisol se...

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...

Pituitary ACTH-secreting tumour presents with variety of clinical features: normal cortisol secretion and ACTH-immunopositive staining and mild hypercortisolism without typical features of Cushing’s disease. We present a 53-year-old male with history of hypertension. First visit (2005): visual loss, bitemporal hemianopsia in campimetry and in MRI pituitary adenoma (2.5 cm) invading cavernous sinus and suprasellar cister. Hormonal study supported panhypopituitarism. After ...

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 and objectives: The treatment with monoclonal antibodies that inhibit proprotein convertase subtilisin-kexin type 9 (PCSK9) is a new group of drugs that allows us to reach the therapeutic targets of low density cholesterol (LDL-c) in patients intolerant to statins or those who despite treatment with maximum doses of them do not obtain a proper lipid control.Material and methods: We performed a descriptive observational study. We include all ...
