Persistent neuropathy and hyperkeratosis from distant arsenic exposure.

The purpose of this case series is to assess long-term sequelae of arsenic exposure in a cohort acutely exposed to arsenic in drinking water from a well dug into a landfill containing arsenical pesticides. Ten of the 13 individuals (or next of kin) in the initial study agreed to participate in the follow-up study. Next of kin provided questionnaire data and released medical information on the three individuals who had died.
