Hyponatremia is the most frequent electrolytic disorder in hospitalized patients, and the syndrome of inappropriate secretion of antidiuretic hormone (SIADH), the most frequent cause of hiponatremia with clinically normal extracellular volume. It consists of a disorder of the regulation of body water that obeys to different causes, mainly cancer, pulmonary illnesses, disorders of the central nervous system and diverse drugs. ⋯ The available data until the moment show that the clinical diagnosis of SIADH made by professionals is mainly not supported on the established criteria drawn by experts and this lack of accuracy probably hits in the therapeutic result. The basis of the treatment of the SIADH is to correct its cause, water restriction, solutes (sodium chloride) and the use of vaptans in case of failure of the previous measures.

Observational Study
Association of carbohydrate 125 antigen with sepsis mortality in critical patients.
The increased synthesis of CA125 in mesothelial cells is connected with pathophysiological processes, also present in sepsis, that link inflammation with systemic congestion. We propose to evaluate serum levels of this biomarker in patients with sepsis and to study its association with the severity and evolution of the disease. ⋯ Septic patients presented high levels of CA125 on the study days, being higher in abdominal infections. In our study, serial determination of CA125 is a prognostic marker of mortality independent of age, origin of infection or severity.

To develop an insight scale for Prader-Willi Syndrome (PWS), a genetically determined neurodevelopmental disorder with different psychopathological and behavioural problems. ⋯ The Adapted version for Prader-Willi patients of the Scale of Unawareness of Mental Disorder (APW-SUD) showed adequate psychometric properties and it is an easy to administer means to assess insight in this population.
