Background: Radiotherapy is part of the complex treatment of pituitary tumors; it is an effective treatment for residual postoperative tumors or recurrent tumors, but cerebrovascular events and secondary intracranial tumors may occur during long term follow-up.Aim: To assess prevalence of cerebrovascular events, secondary intracranial tumors and other neoplasia in patients with non-acromegaly pituitary tumors and craniopharyngiomas submitted to radiother...

Background: Surgery is the standard treatment in patients with medullary thyroid carcinoma (MTC), 43% being biochemically cured postoperative in a large series, the most important prognostic factor being the stage of the disease.Material and methods: We present 3 cases of biochemical cured patients after surgery with different preoperative presentation. Calcitonin and carcinoembryonic antigen (CEA) were measured by chemiluminescence. Histological examina...

Introduction: The incidence of parathyroid carcinoma in primary hyperparathyroidism is less than 1% and the association with ACTH-independent Cushing syndrome is very rare.Case report: A 40-year-old female was admitted for weight gain and reddish-purple striae. One month earlier she had a ¾ parathyroidectomy for primary hyperparathyroidism with histopathological examination showing a parathyroid carcinoma and two parathyroid adenomas. She also had a...

Background: Prevalence and type of amiodarone-induced thyroid dysfunction in a population depend on geographical iodine intake.Aims: To assess differences in amiodarone-induced thyrotoxicosis pattern before and after iodine supplementation.Patients and methods: 84 patients (41M/43F) with amiodarone-induced thyrotoxicosis, aged 60.1±11.9 years, were retrospectively reviewed. 28 patients were resident in former iodine-deficient ...

Background: Screening for primary aldosteronism (PA) needs aldosterone-to-renin ratio (ARR) measurement, followed by confirmative tests.Aim: To assess the clinical value of captopril challenge test (CCT) in PA diagnosis.Methods: Thirty patients were screened for secondary endocrine hypertension; study group consisted in 15 PA patients (7M/8F, aged 44.6±13.3 years). Control group consisted in 15 patients (5M/10F) with negative ...

Introduction: Primary aldosteronism is associated with increased prevalence of cardiometabolic complications. The mechanisms are not fully elucidated, but an association with autonomous cortisol secretion could increase vascular and metabolic risk.Aims: To assess glucocorticoid axis in patients with primary aldosteronism as compared to patients with ACTH-independent Cushing syndrome and control hypertensive patients without gluco or mineralocorticoid exc...

Introduction: Ectopic thyroid tissue (ETT) is a rare entity; it is more frequent in women (80%) and is usually located along the obliterated thyroglossal duct. ETT in the midline is even rarer (1.79%). Incidence of malignancy in this group is lower than in orthotopic thyroid nodules.Case report: A 40 years old woman, resident in iodine sufficient area, but originating from an iodine deficient area, presented for a midline neck mass. TSH and FT4 were meas...

Background: Thyroid nodules were reported with high prevalence in acromegalic patients.Patients and methods: 63 acromegalic patients (16 males and 47 females), aged at diagnosis 43.6±12.7 years were retrospectively reviewed. Median duration of acromegaly was 8 years. 25 patients were residents in iodine deficient areas. GH, IGF1, TSH, FT4 were measured by chemiluminescence (Liaison). Thyroid ultrasound was performed. In suspected nodules,...

Acromegaly control/remission is defined by stringent criteria: normal age-/sex-adjusted IGF1 and random GH (GHr) <1 ng/ml or a GH nadir (GHn) during oral glucose tolerance test (OGTT) of <0.4 ng/ml. However discordances between GH and IGF1 have been recorded in about 30% of patients. We retrospectively analyzed the evolution in patients with acromegaly and discordant GH–IGF1 levels while being treated with somatostatin analogs (SSA) and/or cabergoline (CAB).<p...

Introduction: An improvement of survival in patients with acromegaly was claimed in the last years, with multimodal new therapies.Aims: To assess cure rates of different therapeutic protocols and the impact of these therapies on survival.Methods: 334 patients (224 F/110 M, mean age 48.1±0.7 years) with acromegaly admitted in a single Neuroendocrinology Department between Jan 2001 and Dec 2013 were retrospectively studied by GH...
