Introduction: Secondary causes of diabetes refer to a category in which diabetes is associated with other diseases. They are thought to constitute less than 2% of the total cases of diabetes.Case report: A 56 year-old caucasian man, with no relevant medical history, presented to the Emergency Department with fatigue, polyuria, polydipsia, polyphagia and involuntary weight loss (6 kg in two weeks). He was hemodynamically stable and exhibited a glycaemia o...

Introduction: The endocrine system is often affected in the course of HIV infection. However, hypopituitarism and diabetes insipidus are uncommon disorders in these patients and have been related to drugs, infections of the central nervous system and neoplastic infiltration, in extremely rare cases.Case report: We present a case of a 42-year-old man with HIV infection known since 2005, but undergoing antiretroviral therapy only since 2010 (emtricitabine/...

Background: Continuous subcutaneous insulin infusion (CSII), alongside multiple daily injections (MDI) are the most frequent therapeutic of type 1 Diabetes Mellitus (DM). We aimed to evaluate the effects of the transition from MDI to CSII in the treatment of type 1 DM.Patients and methods: This retrospective longitudinal study analysed patients that received treatment with CSII from 2006 to 2014. Our sample had 85 patients, 35 male (41.2%) and 50 female ...

Background: Diabetes is an important risk factor for major adverse cardiovascular events (MACE). Although the increased risk for MACE is well known, the impact on the in-hospital outcomes remains incompletely understood. Our aim was to evaluate the interrelation between diabetes and MACE in a central hospital in the North of Portugal between 2009 and 2015.Methods: We evaluated retrospectively the hospitalizations due to MACE including stroke or transient...

Aim: The aim of this study was to evaluate the association between thyroid function in Graves’ disease (GD) with high-sensitivity C-reactive protein (hs-CRP), lipid profile, homocysteine, folate, vitamin B12 and insulin resistance.Methods: We performed a cross-sectional of 104 patients with recently diagnosed GD. All participants were in the first cycle of treatment with methimazole. We collected demographic information, body mass indexes (BMI), lab...

Background: Pheochromocytomas (PHEO) are rare neuroendocrine tumors derived from chromaffin cells of the adrenal medulla. Catecholamins’ secretion is associated with a high risk of cardiovascular complications. Malignancy is rare, but still demands effective treatment. Metformin has been shown to have antiproliferative properties in several cancer cell lines, possibly related to its ability to inhibit cell proliferation pathways. Accordingly, we aimed to evaluate the effe...

Background: Maturity onset diabetes of the young (MODY) has an estimated prevalence of 1–5% in the diabetic population, but misdiagnosis as type 1 or type 2 diabetes is common. It comprises a heterogeneous group of monogenic diseases characterized by primary dysfunction of β cell, young onset, autosomal dominant inheritance, without autoimmunity and without ketosis. Early diagnosis remains a challenge with important future implications, since it allows treatment opti...

Introduction: The Marine–Lenhart syndrome is a rare cause of hyperthyroidism that is associated with the simultaneous or sequential presence of characteristics related to Graves’ disease and toxic nodular or multinodular goiter. It’s validity as a disease is controversial and some authors believe that these are cases of hyperthyroidism where both etiologies coexist. The presence of hyperfunctioning nodules in Graves’ disease patients ranges between 0.8 and ...

Introduction: Intensive diabetes type 1 management can be achieved either with multiple daily insulin injection therapy or with continuous subcutaneous insulin infusion (CSII). The former is becoming increasingly popular do to its positive effects on glycemic control.Objectives: Evaluate the evolution of total daily insulin dose (TDID) and weight on patients with CSII.Methods: Patients with CSII of our department were included. Dat...

Papillary carcinoma is the most common histological type of thyroid cancer. The optimal treatment remains controversial, particularly with regard to the papillary microcarcinoma (≤ 10 mm).The aim of this study is the characterization of patients with this condition undergoing surgery in our hospital over a period of 30 years, evaluating treatment outcomes.Between January 1, 1980 and December 31, 2010, a total of 564 patients ...
