Fatal Suicidal Attempt by Deliberate Ingestion of Nicotine-containing Solution in Childhood-onset Depression Mediated through Internet Suicide Guideline: A Case Report

Nicotine is one of the most easily accessible, commonly abused drugs worldwide and if taken in overdose can cause serious clinical presentation, including cardiac arrhythmias and neurotoxicity mediated through oxidative stress. Its toxicity though rare can cause sudden deaths by cardiovascular arrest, respiratory muscle paralysis, and/or central respiratory failure. Here, we describe a case of intentional fatal ingestion of nicotine sulfate decoction used as a mean for fatal suicidal attempt by a 15-year-old adolescent male who was suffering from childhood-onset depression since about 3 months. He developed drooling of saliva, syncopal attacks, paroxysmal episodes of hematemesis, abdominal pain, signs and symptoms of hypoxia, nonfatal atrial tachycardia, and encephalopathy after ingestion of heavy dose of nicotine-containing concoction; however, he recovered successfully within 24-48 hours without any significant cardiac, respiratory, or neurological deficits (except short-term verbal memory). Authors discussed the details of management and reasons behind the reversible encephalopathy and molecular mechanism of nicotine toxicity.
