Objective: To report about a case of acute renal failure due to absence of communication between physician and patient., Case Summary: A 78 year old man with human immunodeficiency virus (HIV) accessed our hospital and was brought to our attention in August 2011 for severe renal failure. Clinical history revealed that he had been taking highly active antiretroviral therapy with lamivudine/abacavir and fosamprenavir since 2006. In April 2011 due to an augmentation in creatinine plasma levels, a reduction in lamivudine dosage to 100 mg/day and the prescription of abacavir 300 mg/day became necessary. Unfortunately, the patient took both lamivudine and abacavir therefore the association of the two medications (lamivudine/abacavir) lead to asthenia and acute renal failure within a few days., Conclusions: This case emphasizes the importance about how physicians must pay very careful attention during drug prescription, most particularly, as far as elderly patients are concerned. In fact, communication improvement between physicians and patients can prevent increase of adverse drug reactions related to drug dispensing, with consequential reduction of costs in the healthcare system., (Copyright © 2012 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

Phenobarbital (PB) has a reputation for safety, and it is commonly believed that PB-related increases in serum aminotransferase levels do not indicate or predict the development of significant chronic liver disease. Here we report of two adult patients with a long history of epilepsy treated with PB who died suddenly: one as consequence of cardiac arrest, the other of acute bronchopneumonia. At autopsy, analysis of liver parenchyma revealed rich portal inflammatory infiltrate, which consisted of mixed eosinophil and monocyte cells, associated with several foci of necrosis surrounded by a hard ring of non-specific granulomatous tissue. Inflammatory reactions of internal and external hepatic biliary ducts were also seen. Our findings illustrate that PB may be associated with chronic liver damage, which may lead to more serious and deleterious consequences. For this reason, each clinician should recognize this entity in the differential diagnosis of PB-related asymptomatic chronic hepatic enzyme dysfunction.
