Introduction: In the area of Immunotherapy, immunological checkpoints, such as CTLA-4, PD-1 or PD-L1, are membrane proteins involved in the immune response that, when inhibited, cause an increase in T cell activity and a consequent anti-tumor effect. However, this inhibition can also cause adverse effects, including endocrinopathies, such as thyroid dysfunction and hypophysitis.Clinical case: 59-year-old man, diagnosed with lung cancer, treated with nivo...

Introduction: Acute Kidney Injury (AKI) is highly prevalent during hospitalization of patients with type 2 diabetes (T2D), and has been associated with increased risk of hypoglycaemia in Intensive Care Units. However, this association in non-critically ill patients is less clear and evidence on the impact of AKI’s severity and duration on hypoglycaemia is lacking.Objectives: To assess the impact of AKI and its severity and duration on the risk of hy...

Introduction: : Adrenocortical carcinoma (ACC) is a rare tumor, often with an unfavorable prognosis. The management of ACC is challenging due to its low frequency and limited experience. The objective of this study was to describe the adverse events (AE) in patients diagnosed with ACC treated in the Divisions of Endocrinology and Oncology at the Ramón y Cajal University Hospital (Madrid, Spain) in the last seven years.Methods: Records of patients wi...

Thyroid dysfunction has been traditionally related to several lipid abnormalities. Indeed, even within the normal range of thyroid-stimulating hormone (TSH) values, a linear increase in total cholesterol, low-density lipoprotein cholesterol and triglycerides and a linear decrease in high-density lipoprotein cholesterol (HDL-C) levels has been observed with increasing TSH. With respect to serum high-density lipoprotein (HDL) cholesterol concentrations, high, normal, or low valu...

Estrogen-producing adrenal gland tumors (EPAGT) are extremely rare, accounting for only 1–2% of all adrenal tumors. They are most commonly observed in men or in children, and are unusual in women. They are almost always malignant even if they seem benign at presentation, and most of them have a poor prognosis. We present a case of a 71-year-old man with painful bilateral gynecomastia, without galactorrhea, over 4 months. Markedly elevated plasma estradiol levels were foun...

Introduction: Pheochromocytoma is one of the major secondary causes of hypertension. The classic triad of pheochromocytoma symptoms of headache, sweating and tachycardia is not present in a high percentage of patients and is sometimes diagnosed as incidentaloma or atypical presentations.Case report: The authors present a 56-year-old man, with no known diseases, referred to Endocrinology evaluation by incidentaloma of the right adrenal gland, from the Pne...

Introduction: Autosomal dominant hypocalcemia (ADH) is a rare condition, caused by activating mutations in the calcium-sensing receptor (CASR) gene. Affected individuals have hypocalcemia with inappropriately low parathyroid hormone (PTH) levels.Case report: A 50-year-old woman, asymptomatic, was referred to our Endocrinology department for investigation of hypocalcemia detected in routine blood analysis (serum corrected calcium was 7.4 mg/dl &#...

Several studies have shown a link between pro-inflammatory activity and the presence or relative deficit of some fatty acids. A low amount of omega 3 fatty acids, appears to promote an inflammatory profile. The omega 6 fatty acids have also the same effect. It is well known that a chronic low-grade inflammation is associated to several diseases, namely, diabetes. The follow-up of children and young people with Type 1 diabetes involves the periodic evaluation of their lipidic p...

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...

Background: Adolescent girls with type 1 diabetes (T1DM) have a higher incidence of metabolic risk factors like hypertension, dyslipidemia, non-alcoholic hepatic steatosis (NASH), abdominal adiposity and polycystic ovarian syndrome (PCOS) when compared with their non-diabetic peers. Moreover, metabolic risk factors seem to appear even in T1DM girls without overweight or obesity. We aimed to determine the prevalence of several metabolic risk factors in adolescent T1DM females, ...
