Organophosphorus poisoning induced delayed neurotoxicity: a report of two cases.

INTRODUCTION: Organophosphorus compounds (OPC) are one of the most commonly used pesticides worldwide and are often misused for suicidal poisoning due to their easy availability. Acute manifestations and management of organophosphorus (OP) poisoning have been reported several times. Organophosphorus-induced delayed neurotoxicity (OPIDN) is a rare delayed presentation of OP poisoning that involves central-peripheral distal axonopathy.

CASE PRESENTATION: In this study, we report two cases of OPIDN developed after a few weeks of OP poisoning. Clinical features, electrodiagnostic study findings, and rehabilitative measures adopted for the patients and their follow-up have been described in the report.

DISCUSSION: Organophosphorus (OP) poisoning may rarely produce features of delayed neurotoxicity, which may gradually appear after acute cholinergic symptoms. This report shows the importance of considering the delayed presentation of possible OPC toxicity in patients with neurological symptoms and a history of OPC exposure.
