Medical complications of bulimia nervosa.

Bulimia nervosa, a mental illness 4 times more common than anorexia nervosa, is characterized by binge-eating followed by compensatory purging behaviors, which include self-induced vomiting, diuretic abuse, laxative abuse, and misuse of insulin. Patients with bulimia nervosa are at risk of developing medical complications that affect all body systems, especially the renal and electrolyte systems. Behavior cessation can reverse some, but not all, medical complications.

Paliperidone: a new extended-release oral atypical antipsychotic.

Paliperidone extended release (ER) is the most recent atypical antipsychotic to become available for the treatment of schizophrenia. It has a unique extended-release delivery system, allowing once/day dosing with steady plasma concentrations of the medication. Several randomized, double-blinded, placebo-controlled trials have shown paliperidone ER to be efficacious in the management of acute schizophrenia as well as for the prevention of symptom recurrence when compared with placebo.
