Background: Tumour growth is critically dependent on blood perfusion, its source of oxygen and nutrients. Therefore, tumour vascularization has become an attractive target for the treatment of many cancers types. The study of endocrine-responsive tumours, in particular, needs improved platforms to screen drugs targeting vascularization that have better resolution and that do not compromise on inter-individual variability.Aim: Hence, we’ve set out to...

Introduction: Sulphonylureas (SU) are an effective therapy for type 2 diabetes (T2DM). As insulin secretagogues, hypoglycemia is a potencial adverse effect. Hypoglycemia may cause neuroglycopenic brain injury, which can mimetize stroke and infections of the central nervous system. Case ReportThe authors report the case of an autonomous 71 year-old woman, with medical history of hypertension and T2DM, treated with enalapril and gliclazide, that was admitted in the Emergency Roo...

Introduction: Diabetes mellitus (DM) results from a defect in insulin secretion and/or its action. The Breast-Cancer Susceptibility Gene 2 (BRCA2), like BRCA1, is a tumour suppressor gene, and its mutation is associated with an increased risk of breast cancer and, in males, testicular cancer. In patients with the BRCA1/2 mutation, the level of Insulin-like Growth Factor (IGF)-1 and, consequently, the peripheral sensitivity to insulin are reduced, suggesting that this ...

Background and aims: Maternal BMI and weight gain are associated with maternal and fetal complications in gestational diabetes (GD), but their relative contribution is not clearly defined. Our aim was to determine the influence of BMI and weight gain in the evolution of GD.Material and methods: Multicenter, retrospective study of women diagnosed with GD at the medical centers of the Portuguese Group for the Study of Diabetes and Pregnancy in 2011. We use...

Background: Catecholamine-secreting tumors that arise from chromaffin cells of the adrenal medulla and the sympathetic ganglia are respectively referred to as pheochromocytomas and paragangliomas. The classic triad of symptoms in patients with pheochromocytoma (PHEO)consists of episodic headache, sweating, and tachycardia. Approximately one-half have paroxysmal hypertension; the rest have either primary hypertension or normal blood pressure. Clinicians should always consider P...

Diabetes Mellitus (DM) has been associated with lung dysfunction and impairment of cardiorespiratory fitness and increasing evidences have suggested that comorbidities and systemic inflammation may be involved in these derangements. However, the results regarding cardiopulmonary dysfunction and its underlying mechanisms in DM are still controversial. In this study, we evaluated the relationship between metabolic variables and inflammation marker, including hemoglobin A1C (HbA1...

Introduction: Thyroid hormones play an important role in bone metabolism. The potential action of prolonged levothyroxine therapy on bone mass reduction is still a matter of debate.Objective: The aim of the present study was to assess the effects of levothyroxine treatment on bone mineral density (BMD) and biochemical bone turnover markers.Methods: We determined thyroid function – TSH and free T4 (FT4), r...

Backgroud: Primary hyperparathyroidism is the most common cause of hypercalcemia, which is associated with an increased frequency of hypertension. However, there are no data on the prevalence of primary hyperparathyroidism in patients who present with hypertension.Clinical case: We present the case of a 40-year-old woman with a history of hypertension for ten years. In 2017 she was referred for evaluation of hypercalcemia. The patient denied any symptoms...

*These authors contributed equally to this work.BackgroundRegular physical activity has a crucial role in the control of Type 1 Diabetes (T1D). Insecurity in the management of insulin therapy and fear for dysglycemia are barriers to the practice of exercise in T1D.AimTo identify barriers to regular physical activity in adult patients with T1D; to evaluate the impact of two ed...

Background: Cerebral malaria may present with altered cognition, severe hemolysis, renal and metabolic dysfunction. The endocrine abnormalities induced by malaria include: hypoglycemia, hypocalcemia, hypercortisolism and compromised pituitary function due to sequestration of drepanocytes in hypothalamo-pituitary portal microvasculature.Aim: To raise awareness for the risk of pituitary dysfunction in severe malaria.Case: A previousl...
