Bottle Gourd (Lagenaria siceraria) Toxicity Diagnosed in the Emergency Department.

BACKGROUND: Bottle gourd (Lagenaria siceraria) is sometimes used in complementary medicine practice for the treatment of chronic ailments. However, there have been reports of toxicity due to consumption of bottle gourd juice, leading to severe abdominal upset and upper gastrointestinal bleeding. CASE REPORT: We present a case of a 41-year-old gentleman who presented to the Emergency Department with multiple episodes of vomiting, hematemesis, and diarrhea after consuming bottle gourd juice. The patient was resuscitated and stabilized with fluids, proton pump inhibitors, and antiemetics. He was subsequently admitted to the General Medicine ward for further management. He continued to receive symptomatic treatment in the ward and underwent esophagogastroduodenoscopy during his hospitalization stay. His symptoms improved and he was discharged stable 5 days later. Why Should an Emergency Physician Be Aware of This? Early recognition of this rare presentation of bottle gourd toxicity is important in our local context, especially where traditional medicine is widely prevalent nowadays. Treatment is supportive. Public awareness of dangerous effects from the consumption of bitter bottle gourd juice and complementary medicine without proper consultation with a practitioner plays a crucial role to prevent further cases. Physicians need to advise patients on the use of traditional medicine and their potential side effects.

Datura and Brugmansia plants related antimuscarinic toxicity: an analysis of poisoning cases reported to the Taiwan poison control center.

INTRODUCTION: Datura and Brugmansia plants, especially Datura species, have been used for their hallucinogenic effects in the United States and Europe; whereas Datura plants have been used as a traditional medicine in many Asian countries. This study was conducted to better understand the pattern and outcome of Datura/Brugmansia plant related poisoning in Taiwan. METHODS: This is a retrospective case series study of all cases with Datura/Brugmansia exposure reported to the Taiwan Poison Control Center between 1986 and 2015. Data for patients with relevant poisoning were reviewed and abstracted. Logistic regression analysis was used to identify potential predictors of the severity of poisoning; bivariate analysis was employed to assess the effectiveness of physostigmine in the treatment of Datura/Brugmansia poisoning. RESULTS: A total of 203 cases involving 114 Datura exposures and 89 Brugmansia suaveolens exposures were eligible for analysis. Using Datura/Brugmansia for a medicinal purpose by the patients without consulting Chinese medicine practitioners was the most common reason of poisoning (81.2%); whereas only 2% of the patients were poisoned after medicinal use associated with the prescription from Chinese medicine practitioners. None of the 203 patients had used Datura/Brugmansia plant for recreational purpose. Most frequently observed clinical effect was mydriasis (53.2%), followed by confusion (40%), tachycardia (35.5%), dry mouth (35.5%), dizziness (34%), dry skin (32.5%), and delirium (31%). Seventy-three cases (36%) had severe effects; none of them died. Misidentification of the plants and ingestion of plant parts other than flowers were positively associated with the severity of poisoning. Forty patients (19.7%) received physostigmine therapy and patients receiving physostigmine had an earlier resolution of central nervous system toxicity than those who did not. CONCLUSIONS: Medicinal use without consulting Chinese medicine practitioners is the main reason for Datura/Brugmansia poisoning in Taiwan. Consumption of parts other than flowers and misidentification of the plants predicted the severity of poisoning in this study. Patients who received physostigmine appear to have earlier improvement in the central nervous system effects. No adverse events were reported from physostigmine administration.

Aconitine intoxication mimicking acute myocardial infarction.

INTRODUCTION: Cardiotoxicity in acute aconitine intoxication is well known; however, elevation of troponin I level and abnormal scintigraphy findings had not previously been reported. CASE REPORT: A 60-year-old man developed chest tightness, syncope and convulsion after ingesting processed Aconitum carmichaeli (Chuanwu) extract for treatment of headache. Electrocardiogram showed first degree atrioventricular (AV) block. Troponin I level was elevated at 14.8 ng/mL 13 hours post-ingestion. Creatine kinase was also increased to 414 U/L. However, echocardiography did not show any abnormal cardiac wall motion. Tc-99m-PYP scintigraphy revealed diffusely increased uptake in the myocardium, suggesting the presence of myocardial necrosis or myocarditis. DISCUSSION: Aconitine poisoning can mimic acute myocardial infarction with chest tightness and elevated cardiac enzymes. Increased cardiac markers and myocardial insult seen in this patient were likely to be related to the toxicity of aconitine. Care should be taken in making the diagnosis in such instances. Management is primarily supportive.

Human Melia azedarach poisoning.

INTRODUCTION: In traditional Chinese medicine, Melia azedarach (Ku-lian) is used orally and topically as an antiparasitic and antifungal agent. Although toxicity of this plant has been widely described in veterinary literature, human poisoning is rarely reported. We describe five patients with M. azedarach poisoning who recovered with supportive care. CASE SERIES: Five patients were identified retrospectively from the database of the Taiwan National Poison Center at the Taipei Veterans General Hospital. Three cases were on-site patients, and two were telephone consultations from outside hospitals. Neurological symptoms were the major manifestation in four cases: weakness, myalgia, numbness, and ptosis. Treatment was symptomatic and supportive; all patients recovered without sequelae. DISCUSSION: It is not known which limonoids are responsible for human toxicity. In the Chinese medical literature, human M. azedarach poisoning is said to occur if six to nine fruits, 30 to 40 seeds, or 400 g of the bark is consumed. Onset of symptoms typically occurs within 4-6 h, but as short as 0.5 h had been documented. In our patients, the onset of M. azedarach poisoning was variable, ranging from a few hours to up to 3 weeks after consumption of the herb. CONCLUSIONS: M. azedarach poisoning may result in gastrointestinal, cardiovascular, respiratory, or neurological effects, and death in severe cases.
