Background: TSH seems to be positively related to the degree of obesity and weight loss seems to induce a reduction in the TSH levels and T3Total. TSH is the first regulatory mechanism of total energy expenditure and T3 regulates energy metabolism and thermogenesis (1)Objective: The aim of this study was to investigate the association between thyroid function and body mass index (BMI) in obese population. And evaluate the influence of weight reduction af...

Introduction: 131I-iodide therapy (RIT) is an important treatment modality for patients with differentiated thyroid carcinoma (DTC). However, despite the overall excellent outcome, some DTC patients with poor prognosis may require multiple doses of radioactive iodine.Aim: The purpose of our study was to evaluate the efficacy of cumulative doses (CDs) of RIT in metastatic DTC patients.Material and methods: A retrospective study was ...

Introduction: Hypothyroidism can affect the nervous system, commonly causing mono and polyneuropathies which show a variable frequency and pattern. Its mechanisms are not fully understood. Symptoms usually correlate better with the duration of the dysfunction rather than with its severity and typically improve significantly after medical therapy.Case report: A 58-year-old woman was admitted at our hospital with a one-year history of progressive weakness ...

Background: Calcitonin is a hormone secreted by thyroid C cells, and is considered an excellent marker for medullary thyroid carcinoma (MTC). However, the use of calcitonin to screen patients with nodular thyroid disease (NTD) remains controversial.Objective: Defining the frequency of hypercalcitoninemia among NTD patients followed at a tertiary referral hospital.Methods: Retrospective analysis of basal calcitonin measurements and ...

Objective: The recommendations for action in a Bethesda category III are to repeat the cytology or to perform molecular tests, and if these are inconclusive, surveillance or surgical indication may be maintained, depending on the risk factors, ultrasound characteristics of the nodule and patient preference. In case of category IV of Bethesda, the recommendation is the surgery. The objective of this study was to evaluate the impact of age, gender and nodule size on the incidenc...

Objective: Thyroid cancer is the most common of the endocrine tumors, with papillary being the most frequent. There is no consensus about prophylactic central cervical dissection in patients with papillary carcinoma of the thyroid. The aim of this study is to analyze surgical complications and the rate of recurrence of papillary carcinoma in patients undergoing total thyroidectomy and prophylactic central cervical dissection, and patients submitted to total thyroidectomy alone...

Introduction: Bilateral macronodular adrenal hyperplasia ACTH-independent (BMAH) represents less than 1% of the causes of Cushing’s syndrome (CS). Studies have shown that mutations in the gene ARMC5 are a common cause of family BMAH and are associated with severe clinical disease and the development of meningiomas.Case report: 64-years-old man presented to our consult due to bilateral macronodular adrenal hyperplasia. He had diabetes mellitus, arter...

Introduction: Leiomyomas are benign tumors originating from the smooth muscle cells. They occur more frequently in the uterus and in the gastrointestinal system. Adrenal leiomyomas are rare tumors arising from the smooth muscle of the adrenal vein and its tributaries.Case report: Man, 72-years-old, referred to Endocrinology in the context of an adrenal incidentaloma (20 mm maximum diametre) detected in abdominal-pelvic CT performed for the study of splen...

Introduction: Central diabetes insipidus (CDI) is a rare complication of acute myeloid leukemia (AML) occurring in less than 0.6% of patients. It is associated with genetic changes in chromosomes 3 and 7. CDI may precede; occur simultaneously or after the diagnosis of AML.Case report: 51-year-old man, with no relevant past medical history, began complaining with polyuria, polydipsia, weakness and weight loss in March 2015.The patient was evaluated in the...

Introduction: Mauriac Syndrome is characterized by the presence of hepatomegaly, growth retardation, delayed puberty and cushingoid features. This entity is traditionally diagnosed during the work-up of hepatic enzymes alterations in children/young adults with type 1 diabetes mellitus (T1DM) with poor glycaemic control. However, the impact of metabolic control in the normalization of hepatic analytic profile is not clarified.Methods and design: Retrospec...
