[Seizures secondary to hypomagnesemia in patients with short bowel syndrome].

Magnesium (Mg) is the fourth most abundant cation in the body and plays a key role in numerous cellular functions such as glycolysis and energy metabolism. Its deficit may cause gastrointestinal disturbances, cardiovascular and neurological diseases. Among the latter, the symptoms may range from muscle weakness and numbness, to lethargy, hyperreflexia, ataxia, tetany, convulsions and coma.

[Prevalence of carbohydrate metabolism disturbances in a population of children and adolescents with severe obesity].

Introduction: There is currently a disproportionate increase in childhood and adolescent obesity worldwide, together with other disorders involving substantial cardiometabolic risk in adulthood, such as alterations in carbohydrate metabolism.

Objective: To establish the prevalence of prediabetes, defined as impaired fasting glucose (IFG) and/or impaired glucose tolerance (IGT) after an oral glucose tolerance test, and the prevalence of type 2 diabetes mellitus (DM-2) in a pediatric population with severe obesity. Additionally, we aimed to assess clinical metabolic differences between prediabetic obese patients and obese subjects without prediabetes.
