[Prevalence of malnutrition in a mid-long term stay unit].

Introduction: Malnutrition is a common health problem, especially in hospitalized patients, where it's associated with longer hospital stays and higher rates of morbidity and mortality. Furthermore, current scientific advances and life expectancy increase, have produced a progressive increase of mid- to long-term stay units (UMLE).

Aims: To determinate the prevalence of malnutrition on admission to a mid- to long-term stay unit, using MNA and VGS and to analyze the possible factors/clinical features associated with malnutrition and its consequences.

Differentiated thyroid carcinoma in a girl with resistance to thyroid hormone management with triiodothyroacetic acid.

Thyroid hormone resistance syndrome is characterized by a reduced target tissue response to the action of thyroid hormone, which leads to high levels of free thyroxine and free triiodothyronine with non-suppressed levels of thyrotropin (TSH). Recently, three cases of papillary thyroid carcinoma associated with thyroid hormone resistance syndrome were published. The main challenge in this situation is the difficulty of maintaining the suppression of TSH levels without producing symptoms of hyperthyroidism.

Metabolic acidosis as a complication of intravenous dextrose administration in a patient with insulinoma.

There are few cases published in literature in which the use of intravenous dextrose as treatment for an insulinoma resulted in a metabolic acidosis. This is due perhaps to the usual method of administration, which is usually at low concentrations, for limited periods or low volumes. We present the case of a woman with suspected insulinoma by laboratory findings in which an endogenous hyperinsulinism was observed.
