Epidemiology of hydrogen phosphide exposures in humans reported to the poison center in Mainz, Germany, 1983-2003.
Poisonings with rodenticides containing hydrogen phosphide-releasing compounds may lead to deleterious organ dysfunction and death. Since data of hydrogen phosphide poisonings is limited to case reports/series, this study was intended to elucidate hydrogen phosphide poisonings based on a 20-year data collection. ⋯ Route of exposure, severity of symptoms, and the necessary treatment differs substantially between unintentional and intentional poisonings. In this study, two initially symptomatic intentional poisonings were later reported fatal. Careful monitoring is recommended in symptomatic intentional poisonings.

Practice Guideline Guidelinebeta-blocker ingestion: an evidence-based consensus guideline for out-of-hospital management.
In 2003, US poison centers were contacted regarding ingestion of beta-blockers by 15,350 patients including 3766 (25%) under 6 years of age; 7415 (48%) were evaluated in healthcare facilities and 33 died. An evidence-based expert consensus process was used to create this guideline. Relevant articles were abstracted by a trained physician researcher. ⋯ Consider the oral administration of activated charcoal if it is available and no contraindications are present but do not delay transportation to administer charcoal (Grade A). 4) Asymptomatic patients who ingest more than the referral dose should be sent to an emergency department if the ingestion occurred within 6 hours of contacting the poison center for an immediate-release product other than sotalol, within 8 hours of contacting the poison center for a sustained-release product, and 12 hours if they took sotalol (Grade C). 5) Ambulance transportation is recommended for patients who are referred to emergency departments because of the potential for life-threatening complications of beta-blocker overdose. Provide usual supportive care en route to the hospital, including intravenous fluids for hypotension (Grade D). 6) Follow-up calls should be made to determine outcome at appropriate intervals for up to 12-24 hours based on the judgment of the poison center staff (Grade D). 7) Asymptomatic patients who are referred to healthcare facilities should be monitored for at least 6 hours after ingestion if they took an immediate-release preparation other than sotalol, 8 hours if they took a sustained-release preparation, and 12 hours if they took sotalol. Routine 24-hour admission of an asymptomatic patient who has unintentionally ingested a sustained-release preparation is not warranted (Grade D).

Case ReportsSevere acute poisoning with homemade Aconitum napellus capsules: toxicokinetic and clinical data.
Aconitum napellus is an extremely dangerous plant that contains various toxic diterpenoid alkaloids, mainly aconitine primarily concentrated in the roots. We report a case of acute intoxication of a 21-year-old man admitted to our Emergency Department after the ingestion, in order to sleep, of three homemade Aconitum napellus capsules. Capsules were measured to contain 237 mg of root and 19 microg of aconitine. ⋯ The calculated half-life of aconitine was 3 hours. To our knowledge, this is the first reported case with an aconitine toxicokinetic-effect relationship. The authors stress that clinicians must be aware of possible occurrence of acute poisoning with Aconitum napellus in European countries and in the United States as herbal medicine is becoming increasingly popular.
