Clinically Significant Envenomation From Postmortem Copperhead (Agkistrodon contortrix).

Over 14,000 copperhead (Agkistrodon contortrix) bites were reported to United States poison centers between 1983 and 2008, and 1809 cases were reported to poison centers in 2014. The copperhead is primarily found in the southeastern United States and belongs to the pit viper subfamily Crotalinae, which also includes the water moccasin (Agkistrodon piscivorus) and rattlesnakes (Crotalus and Sistrurus genera). Postmortem rattlesnakes have been reported to cause clinically significant envenomation; we report a case of a postmortem copperhead causing clinically significant envenomation after inadvertent puncture with the deceased copperhead fang. The copperhead was transected twice, leaving the snake in 3 separate pieces. While handling the snake head, an inadvertent puncture occurred on the right index finger followed by pain and swelling in the affected extremity necessitating antivenom administration. Care should be taken when handling deceased pit vipers due to the continued risk of envenomation.

A Case Series of Clenbuterol Toxicity Caused by Adulterated Heroin.

BACKGROUND: Adulteration of drugs of abuse may be done to increase profits. Some adulterants are relatively innocuous and others result in significant toxicity. Clenbuterol is a ß2-adrenergic agonist with veterinary uses that has not been approved by the U.S. Food and Drug Administration for human use. It is an infrequently reported heroin adulterant. We describe a cluster of hospitalized patients with laboratory-confirmed clenbuterol exposure resulting in serious clinical effects. CASE SERIES: Ten patients presented with unexpected symptoms shortly after heroin use. Seven evaluated by our medical toxicology service are summarized. Presenting symptoms included chest pain, dyspnea, palpitations, and nausea/vomiting. All patients were male, with a median age of 40 years (interquartile range [IQR] 38-46 years). Initial vital signs included a heart rate of 120 beats/min (IQR 91-137 beats/min), a respiratory rate of 20 breaths/min (IQR 18-22 breaths/min), a temperature of 36.8°C (IQR 36.7-37.0°C), a systolic blood pressure of 107 mm Hg (IQR 91-131 mm Hg), and a diastolic blood pressure of 49 mm Hg (IQR 40-70 mm Hg). Serum potassium nadir was 2.5 mEq/L (IQR 2.2-2.6 mEq/L), initial glucose was 179 mg/dL (IQR 125-231 mg/dL), initial lactate was 9.4 mmol/L (IQR 4.7-10.5 mmol/L), and peak creatine phosphokinase was 953 units/L (IQR 367-10,363 units/L). The median peak troponin level in six patients was 0.7 ng/mL (IQR 0.3-2.4 ng/mL). Three patients underwent cardiac catheterization and none had significant coronary artery disease. Clenbuterol was detected in all patients after comprehensive testing. All patients survived with supportive care. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Atypical presentations of illicit drug intoxication may raise concern for drug adulteration. In the case of heroin use, the presence of adrenergic symptoms or chest pain with hypokalemia, lactic acidosis, and hyperglycemia suggests adulteration with a ß-agonist, such as clenbuterol, and patients presenting with these symptoms often require hospitalization.

Airway compromise in children exposed to single-use laundry detergent pods: a poison center observational case series.

INTRODUCTION: Single-use laundry detergent pods (LDPs) were introduced to the United States in 2010 but had been available in Europe as early as 2001. Case reports of unintentional exposures noted vomiting, ocular injuries, respiratory depression, and central nervous system depression. We summarize clinical effects from unintentional LDP exposures reported to a single poison center over 15 months. METHODS: Electronic poison center records were searched using verbatim field and both product and generic codes to identify laundry pod exposures from January 1, 2012, through April 9, 2013. Clinical effects were abstracted to a database and summarized using descriptive statistics. RESULTS: We identified 131 cases between March 2012 and April 2013. Median (interquartile range) age was 2.0 (1.5) years with 4 adult cases; all were coded as unintentional. The most common route was ingestion (120) followed by ocular (14) and dermal (6). Some patients had multiple routes of exposure. Of ingestion exposures, 79 (66%) were managed at home; and 41 (34%) were evaluated in a hospital, of which 9 patients were admitted. The median (interquartile range) age of admitted patients was 1.4 (1.1) years. Relevant findings in these admitted children included emesis (78%), central nervous system depression (22%), upper airway effects (56%), lower respiratory symptoms (33%), seizure (n = 1), and intubation (67%). One child with emesis initially managed at home was subsequently intubated for respiratory distress. DISCUSSION: Exposure to LDP can cause significant toxicity, particularly in infants and toddlers. Compared to traditional detergents, clinicians should be aware of the potential for airway compromise following exposure to LDP.
