Introduction: Noninsulinoma pancreatogenous hypoglycemia syndrome (NIPHS) is an entity with low prevalence (4%), more frequent in neonates and infants and with a male preponderance, characterized by endogenous hyper insulinemic hypoglycemia, not caused by an insulinoma. Pancreatic histology usually reveals diffuse nesidioblastosis.Case report: A 21-years-old man without a remarkable personal or family history was referred describing a 15 kg weight g...

Introduction: Trabecular Bone Score (TBS) is a new non-invasive method to evaluate trabecular bone quality at the lumbar spine. The literature has contradictory results concerning the influence of insulin resistance and adipose tissue on bone, for this reason it is of interest to evaluate factors that determine bone health and risk of fracture in patients with T2DM.Objective: To analyze the relationship between insulin resistance and adipose tissue with ...

Obesity and type–2 diabetes (T2D) represent a global health crisis. However, only a few, and often sub–effective pharmacological tools are available to treat these disorders. Though beneficial for glycemic control, GLP–1 receptor (GLP–1R) agonists show scarce weight–lowering and insulin–sensitizing efficacy.New molecules able to selectively block the activity of the cannabinoid receptor type–1 (CB1R) in periphera...

Measurement of electrical impedance has been proposed as a way to determine whether a hyponatremic patient is hypovolemic or euvolemic. We compare the usefulness of the physical examination (PE) with bioimpedance for determination of volemia in an outpatient hyponatremia clinic.Method: Descriptive prospective analysis. 11 patients attended at the hyponatremia clinic of a tertiary hospital were evaluated. Impedance was measured by a SECA, indicating the p...

ESE Young Investigator AwardIntroduction: GH and IGF1 are thought to promote breast carcinogenesis as circulating levels of GH/IGF1 are positively correlated with breast cancer risk in epidemiologic studies, and mouse models with developmental GH/IGF1 deficiency or resistance are less susceptible to breast cancer development. However, no studies have shown that high levels of circulating GH/IGF1 can promote mammary tumorigenesis. In this...

Introduction: Different studies have published that testosterone therapy in men and women results in decreased HDL cholesterol and increased LDL cholesterol, and therefore an increased cardiovascular risk.Aims: To determine whether testosterone therapy has this effect on lipid parameters and markers of metabolic syndrome (MetSyn) in female-to-male transsexuals (FMT).Material and methods: We studied 50 FMT, aged 27.8±7.6 years,...

There is a direct relation between the degree of glycemic control and the incidence and progression of diabetic complications. In addition improving glycemic control improves diabetic complications.Aim: To assess the degree of glycemic control, according to published guidelines, in treated type 2 diabetes mellitus patients who live in a district of Madrid, Spain.Methods: Cross-sectional study in 501 consecutive patients with T2DM w...

The Nonclassical Congenital Adrenal Hyperplasia (NCCAH) is an autosomal recessive disorder. The importance of the diagnosis in fertile women relies in its therapeutic implications, genetic counseling and antenatal care during pregnancy. Diagnosis is established by the presence of basal 17-OH-progesterone (17-OHP) levels ≧6 ng/ml or stimulated after ACTH test ≧15 ng/ml. Basal values between 2-6 ng/ml or stimulated between 10–15 ng/ml would require further con...

Introduction: The transsexuals are persons that having born with a biological sex feel to belong to the opposite sex. To obtain the sexual characters opposite to his (her) biological sex they need treatment with cross-sex hormones.This treatment with sexual steroids can produce changes in cardiovascular risk factors (CRF). There has been described that hyperhomocysteinemia is an independent CRF that is modifiable by cross-sex hormonal treatment (CHT) in ...

Introduction: Hyponatremia is the most common electrolyte disorder in hospitalized patients. SIADH is characterized by euvolemic hyponatremia with sodium and urine osmolality inappropriately high. The selective antagonist of the vasopressin V2 receptor (tolvaptan) helps to eliminate water free of solute (aquaresis), being effective in treating this condition.Objetive: Evaluate the efficacy and safety of tolvaptan in the treatment of SIADH.<p class="a...
