[Second degree atrioventricular block in mixed connective tissue disease].

INTRODUCTION: Mixed connective tissue disease (MCTD) is characterized by overlapping features of progressive systemic sclerosis, dermatomyositis and systemic lupus erythematosus, and by high rate of antibodies to an extractable nuclear antigen ribonucleoprotein. Cardiac manifestations in MTCD are rare. EXEGESIS: A 58 years old man was admitted for mild fever, a impairment of the general status, muscular pain and a Raynaud's phenomenon. Biologic abnormalities were an inflammatory syndrome, elevated serum CPK and high rate anti-RNP antibodies. Diagnosis of mixed connective tissue disease was made. Shortly after, a Wenckebach atrioventricular block occurred. Systemic corticosteroids were efficient. CONCLUSION: Heart blocks are rarely described in MCTD. Three cases have been reported. It's a systemic complication resulting of an inflammatory process often responsive to steroids.

[Encephalopathy and acute renal failure during acyclovir treatment].

INTRODUCTION: Adverse neurological and renal effects can occur in patients taking acyclovir. Neurotoxicity of acyclovir results from an accumulation of the antiviral and its metabolites in the bloodstream. This can be observed in the elderly or in patients with chronic renal failure, generally in dialysis patients. Acute renal failure results from intratubular crystallization of acyclovir. OBSERVATION: A 78-year-old right-handed woman was admitted in an emergency setting for aphasia. Analysis of the cerebrospinal fluid was normal, but herpetic meningo-encephalitis was suspected and intravenous treatment was initiated with acyclovir. After the second infusion, the patient began to suffer from visual hallucinations, confusion and acute renal failure. Herpes PCR was negative in the cerebrospinal fluid, and the adverse drug reactions regressed completely after 72 hours. CONCLUSION: Renal function has to be checked often in patients given acyclovir for appropriate dose titration. Patients recover prompt from the adverse effects at drug withdrawal.
