IntroductionThe Sodium Iodide Symporter (NIS) is responsible for the active transport of iodide into thyroid cells. Most of differentiated thyroid carcinomas (TC) retain the functional expression of NIS, which allows the use of radioiodide (RAI) as the systemic treatment of choice for metastatic disease. Still, a significant proportion of patients with advanced thyroid cancer fail to respond to RAI therapy (refractory-TC), which makes their management ve...

IntroductionAlthough most patients with COVID-19 have mild symptoms, some develop severe manifestations of the disease, leading to hospitalization and death. Previous studies reported that calcium played a central role in viral infections and replicative mechanisms of SARS-CoV. Hypocalcemia is a common finding among these patients. The aim of this study was to investigate the prevalence of hypocalcemia in a population of COVID-19 patients and to evaluate...

IntroductionSome studies have shown low-density lipoprotein cholesterol (LDL) and triglyceride (TG) levels were significantly lower in high-Killip (III + IV) patients compared with low-Killip (I + II) patients and in those who died after acute myocardial infarction (AMI) compared with those who survived beyond 30 days, which they called lipid paradox. Elevated levels of LDL and triglycerides are important risk factors for cardiovascular disease, ...

BackgroundAutosomal dominant hypocalcaemia, caused by either inherited or de novo mutations in calcium-sensing receptor gene (CASR), is biochemically characterized by the presence of hypocalcaemia, hypercalciuria and inappropriately low levels of PTH. Receptor-activating mutations induce an increase sensitivity to calcium by parathyroid and renal cells, leading to suppression of PTH synthesis and consequently hypocalcaemia. Clinical manifestations are va...

BackgroundType 2 Diabetes Mellitus (T2DM) and Heart Failure (HF) are two directly related diseases associated with considerable morbimortality. The prevalence of HF in T2DM populations is up to 20%, 4 times higher than the general population. Additionally, health-related quality of life, hospitalizations for HF (HHF) and mortality risk are more common when both are present. Hence, HHF risk assessment in T2DM patients may lead to prompt preventive interve...

IntroductionThe Indoleamine 2.3-dioxygenase (IDO) is an enzyme involved in tryptophan metabolism, encoded by the IDO1 gene in humans. In Caucasians, the rs9657182 polymorphism of IDO gene was found to be associated with neurobehavioral complications, especially depression. Several studies in Type 2 Diabetes Mellitus (T2DM) describe psychological factors as barriers to the successful implementation of a healthy eating plan. According to our knowledge ther...

IntroductionAmong other organic functions, Prolactin (PRL) can influence metabolism.AimTo evaluate basal glucose metabolism in women with prolactinoma, according to menstrual cycle, presence of hyperprolactinemia, and dopamine agonist (DA) treatment.Material and methodsCross-sectional study of 17 women with microprolactinoma and 11 healthy controls. Variables eval...

Introduction: Hutchinson-Gilford Progeria Syndrome (HGPS) is a rare disease (1:4 million) characterized by a fatal premature aging. There are 162 cases worldwide, five of them in Portugal. It is caused by a sporadic autosomal dominant mutation in LMNA gene that encodes an abnormal variant of the laminin-A protein, named progerin. Although most babies born looking healthy, they begin to display some characteristics of Progeria around 18–24 months of life. The ear...

Introduction: Addison Disease is a rare condition with an estimated incidence in the developed world of 0.8 cases per 100 000 population. It is associated with relevant morbidity and mortality rates, but once the diagnosis is made it can be easily managed. When Addison Disease is associated with other autoimmune diseases, the diagnosis of polyglandular autoimmune syndrome can be set. The recognition of symptoms and signs can be challenging and clinicians should be aware of aty...

Introduction: Malignant or necrotizing external otitis (MEO) is an invasive infection between external auditory canal and skull base. It is more frequent in elderly and in diabetic patients or with compromised immune system. As MEO advance osteomyelitis can developed. It is a severe and potential mortal complication of external otitis (EO).Clinical case: 78 years old man with history of type2 diabetes (good metabolic control) and right ear external otiti...
