Aconitum is an extremely dangerous plant that contains various toxic diterpenoid alkaloids, primarily concentrated in the roots. We report a case of acute intoxication of a 60-year-old man admitted to our emergency department after ingestion of a large amount of homemade aconitine decoction. At presentation about one hour after intake, the patient was unconscious and electrocardiographic analysis showed a ventricular tachycardia/fibrillation. Several times defibrillation was applied and antiarrhythmic agents were administered, but the patient still exhibited a refractory ventricular fibrillation and failed to return to spontaneous circulation. Sustained cardiopulmonary resuscitation finally produced a pulsatile cardiac rhythm at two hours after intake. The patient was discharged from our hospital on day 8. The authors stress that clinicians must be aware of the possible occurrence of life-threatening ventricular arrhythmia in cases of aconitine intoxication and be prepared to persist with prolonged CPR as necessary.

Purpose: Various electrocardiogram (ECG) changes can occur in patients with acute organophosphate poisoning (OPP) and may be associated with the clinical severity of poisoning. The present study aimed to evaluate the extent and frequency of ECG changes and cardiac manifestations, and their association with acute OPP clinical severity. Methods: Seventy-two adult patients admitted to our emergency department with a diagnosis of acute OPP were studied retrospectively. ECG changes and cardiac manifestations at admission were evaluated. ECG changes between respiratory failure (RF) group and no respiratory failure (no RF) groups were compared. Results: Prolongation of QTc interval (n=40, 55.6%) was the most common ECG change, followed by sinus tachycardia (n=36, 50.0%). ST-T wave changes such as ST segment elevation or depression and T wave change (inversion or non-specific change) were evident in 16 patients (22.2%). Prolongation of QTc interval was significantly higher in the RF group compared with the no RF group (p=0.03), but was not an independent predictor for RF in acute OPP (OR; 4.00, 95% CI; 0.70-23.12, p=0.12). Conclusion: While patients with acute OPP can display ECG changes that include prolongation of QTc interval, sinus tachycardia, and ST-T wave changes at admission, these changes are not predictors of respiratory failure.

Phytolaccaceae had been used as a pharmaceutical drugs or food in Korea. Nowadays, it is rarely used due to its toxicity, and then, case reports as to poisoning also are rare. Recently, Authors experienced a case of an occurrence in a group intoxication after ingestion of roots of phytolacca american a misidentifying as arrowroot. We report this case with review of phytolacca radix poisoning.

Purpose: Unrefined tablets prepared from Aconitum tubers are occasionally used in Korean folk medicine. This study defines the potential sources, clinical toxicology, and treatment of aconitine poisoning. Methods: A retrospective survey was conducted in 63 patients in the ED of a tertiary University Hospital with suspected toxicity from an unrefined tablet prepared from Aconitum tubers from 1999 to 2007. Results: A total of 63 cases enrolled included 26 men and 37 women, aged 30 to 86 years. Forty-eight patients ingested aconitine tablets as digestives, 26 tablets on average. After a latent period of 30 to 450 minutes, patients developed a combination of neurologic (87.3%), gastrointestinal (82.5%), cardiopulmonary (41.3%), and other (28.6%) features typical of aconitine poisoning. Initial ECG abnormalities revealed dysrhythmia (61.9%), conduction disturbance (42.9%), and abnormal waveforms (39.7%), with 28.6% of patients having normal ECGs. All patients received supportive treatment or close observation regardless of ingestion amounts. Patients with hypotension or ventricular arrhythmia were treated with inotropic agents or amiodarone. Conclusion: Toxicologic signs and symptoms can occur after the consumption of aconitine tablets, regardless of ingestion amount. The risk occurs because of inadequately processed aconitine roots. This study will provide important data for public education and distribution regulations for Aconitum sp. in Korea.

The plant Korean rosebay are members of the Ericaceae(Heath) family and may contain grayanotoxins, which exert toxic effects by binding to sodium channels in cell membranes. We had experience of 2 cases of Korean rose bay intoxication, who exposed to Rhododendron mucronulatum. Patients were presented to our ED with nausea and vomiting, hypotension, and dizziness or depressed mentation. The patients were performed monitoring and supportive treatment and were fully recovered within 48hours. Korean rose bay intoxication should be considered in patients with clinical evidence of gastrointestinal irritation, cardiac arrhythmias, and/or neurologic signs without identifiable causes, especially in spring or early summer.

Some carnivorous gastropods have heat stable tetramine toxins in their salivary glands. This toxin is an autonomic ganglionic blocking agent that enables them to catch the prey easily by paralyzing their targets. Acute tetramine toxin poisoning in humans from eating whelks has been well described based on numerous cases, but is rare in Korea. Symptoms of tetramine poisoning include eyeball pain, blurred vision, headache, dizziness, muscular twitching, tingling of hands and feet, weakness, paralysis and sometimes collapse. Gastrointestinal symptoms, such as abdominal pain, nausea, and vomiting can also occur. However, intoxication is self-limiting and patients will usually recover in about 24 hours. Herein, we report 2 cases of tetramine poisoning after ingestion of Buccinum striatissinum as meat and soup.
