Twelve patients with 3,4-methylenedioxymethamphetamine (MDMA) toxicity from a single rave event presented to multiple San Francisco Bay area hospitals with various life-threatening complications including seizures and hyperthermia. Eight required emergent endotracheal intubation and six had hypotension. Hyperkalemia, acute kidney injury, and rhabdomyolysis were present in most of the patients. In all, 2 patients died, 4 survived with permanent neurologic, musculoskeletal, and/or renal sequelae, and 6 survived without any apparent lasting deficits. Hyperthermia was present in 10 patients and was severe (40.9-43° C) in 7. Using multiple cooling methods, the average time to achieve cooling was 2.7 hours. Serum drug analysis was performed on 3 patients, demonstrating toxic MDMA concentrations without the presence of other xenobiotics. Two capsules confiscated by police at the event contained 82% and 98% MDMA, respectively, without other pharmacologically active compounds. Capsule #2 contained 270 mg MDMA, which is more than twice the amount of MDMA usually contained in 1 dose. The MDMA-induced hyperthermia significantly contributed to the morbidity and mortality in this case series. Factors contributing to the severity of the hyperthermia include ingestion of large doses of MDMA, a warm ambient environment, and physical exertion.
Although pseudomembranous colitis is relatively common following antibiotic exposure, there have been few reported cases of pseudomembrane formation involving the small intestine. Herein we report a case of pseudomembranous enteritis of the small and large intestine that occurred after antibiotic exposure. The etiologic organism appears to be Clostridium difficile, as evidenced by the characteristic pseudomembranous lesions and a positive ELISA for toxin A in an ileal tissue specimen.
Background: Tapentadol (TAP) and tramadol (TRA) provide pain relief through similar monoaminergic and opioid agonist properties. Objective: To compare clinical effects and medical outcomes between TAP and TRA exposures reported to the National Poison Data System of the American Association of Poison Control Centers. Methods: A retrospective cohort study was conducted analyzing national data for single medication TAP or TRA cases reported from June 2009 through December 2011. Case outcomes, dichotomized as severe versus mild; clinical effects; and use of naloxone were compared. Results: There were 217 TAP and 8566 TRA cases. Significantly more severe outcomes were associated with TAP exposures for an all-age comparison (relative risk [RR] = 1.24; 95% CI = 1.04-1.48), and for the <6-year-old age group (RR = 5.76; 95% CI = 2.20-15.11). Patients with TAP exposures had significantly greater risk of respiratory depression (RR = 5.56; 95% CI = 3.50-8.81), coma (RR = 4.16; 95% CI = 2.33-7.42), drowsiness/lethargy (RR = 1.38; 95% CI = 1.15-1.66), slurred speech (RR = 3.51; 95% CI = 1.98-6.23), hallucination/delusion (RR = 7.25; 95% CI = 3.61-14.57), confusion (RR = 2.54; 95% CI = 1.56-4.13) and use of naloxone (RR = 3.80; 95% CI = 2.96-4.88). TRA exposures had significantly greater risk of seizures (RR = 7.94; 95% CI = 2.99-20.91) and vomiting (RR = 1.96; 95% CI = 1.07-3.60). Conclusion: TAP was associated with significantly more toxic clinical effects and severe outcomes consistent with an opioid agonist. TRA was associated with significantly higher rates of seizures and vomiting.
This is the second case report of a seizure occurring in a child after an unintentional ingestion of levothyroxine. The maximum amount possibly ingested is much lower than that previously reported. Pediatric ingestion of less than 5 mg of levothyroxine may result in serious outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
