Neuropathie optique lors d'un traitement par disulfirame [Optic neuropathy while taking disulfiram]

INTRODUCTION: Disulfiram has been used since the late 1940s to treat chronic alcoholism. This drug interferes with alcohol metabolism resulting in an acetaldehyde increase. This causes painful symptoms, encouraging abstinence. Side effects include rare cases of bilateral optic neuropathies. Visual recovery occurs frequently upon cessation of therapy. METHOD AND OBSERVATION: We retrospectively studied patients referred for visual loss while treated with disulfiram between 1987 and 2005. Fourteen patients (three females, 11 males; aged 35-62 years) complained of visual loss, but a toxic, disulfiram-related, optic neuropathy was diagnosed in only five patients. Following cessation of disulfiram therapy, visual acuity and field improved in all five patients. DISCUSSION: and conclusion: When disulfiram toxicity is suspected with optic neuropathy, cessation of treatment is mandatory. Visual prognosis is good in the majority of cases, as illustrated by our series. Disulfiram toxicity can be diagnosed only after excluding all other possible causes of visual loss.

In 2011, new tools to evaluate life expectancy are available. Controversy about PSA-based screening for prostate cancer is still going on, with new data from the US Preventive services task force. A brief behavioral treatment for insomnia can be efficient and durable. Gliptines are be useful to avoid treatment-induced hypoglycemia in diabetic patients. New Alzheimer diagnostic criteria, including biomarkers, have been published.
