Two groups of researchers report on the prevalence of HIV and hepatitis C virus infections in different inmate populations — people in provincial prisons in Quebec, and adult and young offenders admitted to remand facilities (jails, detention centres and youth centres) in Ontario. In both studies, injection drug use was the most important risk factor, and the prevalence of hepatitis C virus infection was much higher than that of HIV infection. In a related commentary, Elliott discusses the continued lack of response by government policy-makers regarding the implementation of evidence-based harm-reduction strategies in prisons.

**Disclosing medical errors to patients**

In this issue's Clinical Vistas Briefs, readers are asked to diagnose a **persistent asymptomatic lesion** on the sole of a 70-year-old man's foot, to determine the source of **sharp pain** in the big toe of a 72-year-old man and to spot the cause of **progressive dyspnea** in a 57-year-old woman after a cerebral artery infarction (page [249](http://www.cmaj.ca/lookup/volpage/177/249?iss=3)).
