GH deficiency (GHD) in adults is characterized by a tendency towards fat mass gain and may predispose to type 2 diabetes mellitus.GH replacement (GHR) is associated with impaired insulin sensitivity shortly after starting therapy, reflected by increased fasting glucose and insulin levels. Available evidence suggests that concerns regarding glucose intolerance in patients receiving long-term GHR have not been substantiated. However, several environmental and lifestyle-related f...

Generously supported by IPSEN)-->GH replacement (GHR) in adults has demonstrated to improve body composition, inflammatory cardiovascular biomarkers and quality of life. However, this benefit is uneven, and factors that stratify treatment response are required.According to current guidelines, low IGF-I levels in specific conditions provide strong evidence for GH deficiency (GHD). Nevertheless, normal levels do ...

Introduction: Nodular thyroid disease is a common problem in clinical practice. Fine-needle aspiration (FNA) has become the principal test in the diagnosis of nodular thyroid disease. However, sometimes the information provided by this procedure is not definitive as it happens in those cases where the cytologic specimens are suspicious or indeterminate and a clear cytologic diagnosis can not be made. Based on that, we therefore undertook a study to investigate the histological...

Introduction: Langerhans cell histiocytosis (LCH) is a rare granulomatous disease of unknown etiology. LCH may be localized or be a systemic disease. The diagnosis is frecuent in pediatric age. In adults, infiltration is most frecuently in bones, lungs and skin, and shows particular predilection for hypothalamo-pituitary axis.Case: A 51 years old man was referred due to polyuria of ~15 l of daily urine output. His past medical history revealed bronchiect...

Introduction: Islet hyperplasia and nesidioblastosis are described in the non neoplastic pancreas of patients with gastrinoma. It is not definately established whether hypergastrinemia can influence these changes. Moreover, rarely insulinoma and gastrinoma occur in the same patient but cases of single tumours cosecreting both insulin and gastrin have been described. Otherwise, the syndrome of hyperinsulinemic hypoglycaemia with nesidioblastosis after Roux-en-Y gastric bypass h...

Purpose: The aim of this study was to evaluate the sensitivy of contrast-enhanced ultrasound (CEUS) in the detection of pathological parathyroid gland in patients with primary hyperparathyroidism in comparison to the 99m-MIBI-SPECT scintigraphy.Methods: 29 patients consecutive (22 female, 7 male) with biochemically confirmed primary hyperparathyroidism, who underwent preoperative imaging with Technetium 99m-MIBI-SPECT scintigraphy and CEUS and subsequent...

Introduction: Incidentally discovered adrenal masses (incidentalomas) are common and in some cases differential diagnosis could be a challenge.Case report: A 55-years old woman presented with an incidental left adrenal mass of 36mm discovered on an abdominal ultrasound. As sole background she underwent resective surgery of an ovarian serous cyst. She denied symptoms like flushing, headache, diaphoresis or palpitations. Physical examination was irrelevant...

Introduction: Clinically non-functioning pituitary adenomas (NFPA) are heterogeneous group. Some previous research has found that this type of pituitary adenomas may be smaller and have better prognostic in men. The aim of this study is to analyze if there are gender-related differences in NFPA.Material and methods: Retrospective study of patients with NFPA followed up in regional hospitals (Community of Madrid, Spain). All NFPA had molecular analysis. T...

Background: Acromegaly is usually caused by a benign pituitary tumour, with increased production of growth hormone (GH) and insulin-like growth factor 1 (IGF-1). Treatment options include surgery, followed by pharmacological treatment with dopamine agonists, somatostatin analogues, GH receptor antagonists or radiotherapy. Treatment optimization is important to decrease the burden of this often-chronic disease on the patient.Objectives: To evaluate the ef...

Introduction: Primary aldosteronism (PA) is the most common cause of secondary hypertension (5–10%) and it is underdiagnosed. Less than 50% of patients with PA have hypokalemia. The tests for determinate subtype of PA are cross-sectional imaging (adrenal CT or MRI) and adrenal vein sampling (AVS). The AVS seems to be important to direct appropriate therapy and surgery is the preferred treatment for patients with unilateral disease.Material and metho...
