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...

Objective: To evaluate the prevalence of thyroid cancer in patients with suspected thyroid nodule referred from primary care.Methods: Retrospective cohort study which included patients with suspected thyroid nodule referred from primary care to a high-resolution thyroid nodule clinic. Demographic and clinical characteristics were collected, all patients underwent thyroid ultrasound and subsequently, a fine-needle aspiration (FNA) was performed if thyroid...

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....

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: Differentiated thyroid cancer (DTC) represent 85- 90 % of all thyroid cancer cases. Most of these have an excellent prognosis with standard treatment. However, between 7 and 23% will develop distant metastases and, of these, more than 65% will become radioactive iodine-refractory. In some of these patients who are considered to be radioiodine-refractory with rapidly progressive or symptomatic disease, or in patients who are not candidates for other therapies, the...

Objective: The aim of this study is to evaluate the effectiveness of once-weekly exenatide on metabolic control, weight, blood pressure, and lipid profile in obese patients with type 2 diabetes (T2DM), and to assess possible predictive factors of response.Material and methods: Retrospective observational study, conducted with adult obese (BMI ≥30 kg/m2) T2DM subjects that had been initiated once-weekly exenatide following routine clinica...
