Background: High prevalence of hypovitaminosis D in diabetic patients has been reported and has been associated with microvascular complications and insulin treatment in type 2 diabetic patients.Methods: Observational study in 92 inhospital patients with different types of diabetes. We analyzed the relationship between serum 25-hydroxyvitamin D (25-OHD) concentration and the clinical features associated with diabetes.Results: Of 36...

Objective: Acromegaly (ACRO) is associated with abnormal bone remodeling and reduced volumetric bone mineral density (vBMD) at the lumbar spine and proximal femur. Circulating microRNAs (miRNAs) modulate the activity of osteoblasts and osteoclasts, and are currently being investigated as potential biomarkers of osteoporosis. The aims of our study were: 1) To identify differentially expressed miRNAs in the serum of five patients with active ACRO vs. healthy controls, and 2) To ...

Introduction: Neonatal diabetes mellitus is a rare form of diabetes, diagnosed within the first six months of life. We report a case of a 24-year-old patient with permanent neonatal diabetes.Case Report: The patient had no relevant family history. Her mother had no gestational diabetes. Personal history included: Normal birth weight, polycystic ovarian syndrome and ovarian teratomas. She was diagnosed of diabetes at 3 months of age, starting immediately ...

Introduction: MODY 5 is a rare type of dominantly inherited diabetes mellitus. It is asociated with mutations of the hepatocyte nuclear factor-1beta (HNF-1beta) gene. They are mostly missense mutations that produce truncated proteins with a variable clinical spectrum that encompasses among others: kidney, genital and pancreatic abnormalities.Case-report: A 35 years-old man without relevant medical history, presented with acute hypergycemia (541 mg/dl) an...

Introduction: Roux-en-Y gastric bypass (RYGB) places patients at an increased risk of hypocalcemia due to the reduction in calcium absorption (because the procedure bypasses the duodenum and jejunum) and vitamin D deficiency. Subsequent thyroid surgery increases the risk of severe hypocalcemia due to potential post-operative hypoparathyroidism. Only a few cases have been published before of this kind of treatment-challenging hypocalcaemia.Case report: We...

Introduction: Diabetes mellitus is a condition on the increase, carrying a high risk of macro and microvascular disease. Previous studies suggest a link between microvascular and macrovascular complications in diabetes. However, just a few studies have investigated whether the presence of peripheral vascular disease (PVD) is associated with other macrovascular and microvascular complications in diabetes patients. So, this was the aim of our study.Patient...

Introduction: It is well known that diabetes confers a substantial burden of macrovascular disease. However, just a few studies have investigated the association between diabetic kidney disease (DKD) and cardiovascular disease. The purpose of this study is to investigate whether the presence of DKD is associated with macrovascular disease in diabetic patients.Patients and methods: 98 diabetic patients (48 males/50 females) were included in the study. DKD...

Introduction: HNF-1β maturity-onset diabetes of the young (MODY5) is uncommon, nevertheless accurate diagnosis guides individualized management and informs prognosis in probands and relatives.Objective: To emphasize the importance of the appropriate use of clinical, biochemical and genetic investigations for the correct classification of diabetes etiology.Case-report: A 35-year-old overweight Latin-American male was diagnosed ...

Introduction: Maternally inherited diabetes and deafness (MIDD), is a rare entity. Most commonly, it is related to a point mutation in the mitochondrial DNA (mtDNA) at position 3243 (m.3243A>G) encoding the gene for tRNA. A high index of suspicion is required for the diagnosis due to a wide heterogeneity in its clinical presentation which reflects different levels of mutated mtDNA among mitochondria in a given tissue (heteroplasmy). Thyroid cancer risk has never been speci...

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...
