Introduction: Cystic masses of neck consist of a variety of pathologic entities. The age of presentation and clinical examination narrow down the differential diagnosis. In adults are considered to be malignancies until proven otherwise (thyroid lesions, salivary gland neoplasms, metastatic squamous cell carcinoma and lymphatic malformations such as the cystic lymphangioma. Ultrasound (US) is often used for initial evaluation. Computed tomography (CT) and MRI provides addition...

Introduction: Subclinical hypercortisolism (SH), a condition of biochemical cortisol excess without the classical signs or symptoms of overt hypercortisolism, is thought to be present in the 5–30% of patients with incidentally discovered adrenal mass (adrenal incidentalomas). Some evidence suggest that this condition may lead to long-term consequences of cortisol excess, but indication and potential benefits of adrenalectomy in this state are still in doubt. We analyse a ...

Introduction: Multiple Endocrine Neoplasia type 1 is an underdiagnosed autosomal dominant disorder, with inter and intrafamilial variability without a genotype-phenotype correlation.Case report: A young female (born in 1986) presented with galactorrhea and secondary amenorrhea in 2002, and investigation revealed a prolactinoma. Her brother (born in 1982) presenting gynecomastia and erectile dysfunction at age 21, was also diagnosed with prolactinoma. The...

Introduction: Contradictory associations between sleep disturbances and changes in cortisol levels or unfavourable metabolic conditions like obesity and diabetes mellitus have been observed.The aim of the present study was to examine salivary cortisol in persons with reduced sleep quality and to evaluate the relationship between sleep quality and metabolic parameters.Methods: The Pittsburgh Sleep Quality Index (PQ8I) was used in 15...

Macroprolactin is a collective term for a heterogenous group of high molecular mass forms of prolactin with minimal bioactivity in vivo. Objective: to determine prevalence of macroprolactinemia (macroPRL) and clinical characteristics of patients with hyperprolactinemia (hyperPRL) who underwent assessment for macroPRL in Endocrinology outpatient clinic.Methods: We reviewed the medical records of 54 patients who were evaluated for macroPRL between...

Vitamin D has a role in the pathogenesis of thyroid autoimmunity.There is evidence in humans that serum levels of 1,25(OH) D3 were found to be significantly lower in patients with autoimmune thyroid diseases.We have evaluated all samples performed in the endocrine labs tested for vitamin D, AbTg, Ab-TPO and TSH from 2006 to 2015; 29216 samples for vitamin D and 41014 for TSH, AbTg and TPO were considered.We s...

Aim: To know if Tg levels after treatment (total thyroidectomy and radioiodine ablation) in the DTC can predict their prognosis in the long term.Material and methods: Basal Tg and Tg after rh-TSH were measured in 229 patients with DTC without any evidence of residual tumour (negative neck ultrasonography) after treatment. The group was followed until tumour recurrence or, if recurrence was not found, a minimum of 12 month (mean ± SD =63±37 mont...

Introduction: Incidental papillary thyroid carcinoma (PTC) in patients undergoing thyroidectomy for benign multinodular disease is a well-recognised finding. Its true prevalence remains uncertain and shows great variability between studies, ranging from 7–25%. Our purpose was to review the prevalence of PTC in thyroid glands removed for benign nodular disease at a Northern Portuguese tertiary hospital.Methods: From December 2012 to December 2014, th...

Thyroid cancer is one of the most frequent malignancies of the endocrine system, and its incidence is predicted to become the fourth leading cancer diagnosis by 2030. Among thyroid carcinomas, anaplastic thyroid cancer (ATC) is the most aggressive and lethal tumor, which grows very rapidly, invades adjacent tissues and metastasizes, causing death in 1 year from diagnosis. We recently showed that in thyroid cancer PATZ1 expression is downregulated compared to normal thyroid and...

Introduction: Bilateral macronodular adrenal hyperplasia (BMAH) is a rare aetiology of Cushing syndrome. Familial clustering suggests a genetic cause that was recently confirmed, after identification of inactivating germline mutations in armadillo repeat containing 5 (ARMC5) gene.Clinical case: A 70 years old female admitted due to femoral neck fracture in May 2014, presented central obesity, rubeosis and hypertension. Laboratory work up reveale...
