Introduction: Primary thyroid angiosarcoma (TAS) is a rare malignancy that arises from endothelial cells, and nearly all reported cases originate from the Alpine region of central Europe. Most of the patients are female, elderly, with a history of goiter. Generally, TAS arises as a painless infiltrating mass and patients present with compression symptoms due to the brisk tumor growth. Other TAS clinical presentations are varied and highly non-specific. Metastasis occur early i...

A 50-year-old woman with no history of interest who was admitted in hospital for progressive headache 2 weeks of evolution refractory to treatment that was accompanied by emetic syndrome and paresthesias in face and arms. A CT scan of the skull (urgency) was performed which was normal. Neurology improves with analgesia and steroids, presenting mild drowsiness and mild hyponatremia (121 mEq/l). A cerebral MRI was performed, showing a right subacute hemorrhagic adenoma of 1 cm t...

Introduction: Hypercalcemia can be caused by a variety of pathologies/factors. Vitamin D plays a central role in calcium homeostasis, where a tight control of its metabolism is necessary. Inadequate 24-hydroxylase-enzime (CYP24A1) activity leads to failure of 25-hydroxyvitamin and 1,25-dihydroxy-vitamin D3 inactivation, resulting in hypercalcemia.Case report: An asymptomatic, 22-year-old woman was admitted in an Endocrinology appointment for evaluation o...

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: In patients with type 1 diabetes, exercise has not consistently been shown to improve glycemic control, as measured using HbA1c levels. Participation in competitive sports may even worsen glycaemic control. Free radicals and oxidative stress markers are known to increase during acute exercise in parallel to decreased circulating antioxidant concentrations. We aimed to analyze the effects of chronic and acute exercise on circulating HbA1c and fructosamine levels.<...

We present the case of a 24-year-old melanodermic male patient from Angola referred to the Endocrinology department of a central hospital, in Lisbon, Portugal. He presented skeletal deformities and joint laxity, and numerous mucosal neuromas of the oral cavity since early childhood. Recurrent diarrhea was also reported but elevated blood pressure was not observed at that time. Multinodular goiter (nodules>40 mm) was identified in physical examination and microcalcification...

This is a 38-year-old male, a regular user of a gym with the sole purpose of improving his physical performance and muscular strength and habitual consumer of hyperproteic dietary supplements. Among his PAs he denies toxic habits, and highlights the removal of the right testicle in childhood. Consultation for decreased desire and sexual potency, together with pain and turgor in the left breast; hair loss at the frontal level, in analytic carried out by the Primary Care Physici...

Aim: Obesity was shown to be related to global cognitive decline, being especially altered the executive function and the information processing speed. Bariatric surgery (BS) is an effective means of weight reduction in severely obese patients and correlates with improvements in neurocognition. The mechanisms underlying these improvements are not fully elucidated.Material and Methods: Prospective, observational study, including consecutive patients that ...

Objective: The carbohydrate metabolism dysfunctions are common in critical ill patients with diabetes or stress hyperglycaemia and the correct management of them has an important prognostic value. Despite its limitations, capillary glucose (CG) was collected more than arterial glucose (gold standard) because of its good correlation. However, the usefulness of intermittent intersticial glucose monitoring (IGM) in keeping blood glucose within target range in critical ill patient...

Background: 3q29 microduplication syndrome is a very uncommon genetic disorder with fewer than 40 cases reported, although the wide and heterogenous clinical features make this syndrome hard to diagnose. This syndrome is clinically milder than the 3q29 microdeletion syndrome, which contributes to the high rate of underdiagnosed cases that may exist. Patients affected with this syndrome have a complex phenotype, with non-specific clinical features such as autism spectrum disord...
