Issues of internal medicine in psychiatric patients.

In opposition to opinions of a sectorialization of psychiatric illness, phenomena of comorbidity due to susceptibility of psychiatric patients to contract other diseases--whose co-presence is difficult to translate and treat--are more and more evident. In this review we have marked main issues of internal medicine in psychiatric patients. This review will discuss particularly main cardiovascular diseases (CAD, VTE), lung diseases (COPD,asthma, restrictive lung disease) gastroenterologic disease (IBS, coeliac disease, ulcerous rectocolitis), diabetes and metabolic syndrome, more likely infections verified in these patients (HIV, viral hepatitis), cancers considerably underlined (breast cancer, colon-rectal cancer and lung cancer), internistic issues in alcohol abuse which is a frequent state in these subjects. A special chapter is dedicated to antipsychotics. These drugs are characterized by a complex action modality and by frequent interactions with a large number of other drugs.
