RESUMEN
Liquid nicotine used in electronic cigarette devices is highly concentrated, unreliably packaged, and poorly regulated. We present a case report of a 6-year-old female who developed severe toxicity and required intubation after an unintentional oral ingestion of approximately 703 mg (35 mg/kg) of liquid nicotine, with accompanying serum and urine concentrations of nicotine and its metabolites. Analysis of the ingested liquid suggests a nicotine concentration of 140.6 mg/mL in the purchased commercial product, or 234% of its labeled concentration. Clinicians should be aware of these products and the potential severity of toxicity they may incur.

Objective: We describe the clinical effects of, and products associated with, acute exposures to cannabis during the early legalization period of recreational cannabis in Oregon and Alaska. Methods: This was an observational study of Oregon/Alaska Poison Center data between 4 December 2015 and 15 April 2017. A standardized data collection instrument was created for this study that captured information about cannabis product description, route of exposure, intentional vs unintentional exposure, product dose, product manufacture source, product ownership source, initial vital signs, clinical signs and symptoms, and subject disposition. Subjects were included if the Poison Center received a call about an acute exposure to cannabis from the subject, subject's family member or friend, or healthcare worker participating in the subject's care. Subjects were excluded if there was no evident exposure, the exposure was chronic, there were co-ingestants, or the subject was non-human (e.g. pet). Results: Two hundred fifty three individuals were acutely exposed to cannabis (median age 20 years; range 8 months - 96 years; 54.2% males): 71 (28.1%) children (<12 years), 42 (16.6%) adolescents (12-17 years), and 140 (55.3%) adults (≥18 years). Children were most likely to unintentionally (98.6%) ingest (97.2%) homemade (35.2%) edibles (64.8%) belonging to a family member (73.2%) and experience sedation (52.1%). Adults were most likely to intentionally (88.6%) ingest (66.4%) retail (40.0%) edibles (48.6%) and experience neuroexcitation (47.1%). Adolescents' exposures had similarities to both adult and children; they were most likely to intentionally (81.0%) ingest (50.0%) homemade (23.8%) edibles (45.2%) belonging to a friend (47.3%) and to experience either neuroexcitation (42.9%) or sedation (40.5%). Among all ages, tachycardia and neuroexcitation were more likely following inhalation exposures compared to ingestions. Eight subjects were admitted to an intensive care unit, including three patients who were intubated; one subject died. Edibles were the most common products to cause symptoms in all age groups, while concentrated products were more likely to lead to intubation, especially when ingested. Children in particular had a higher likelihood of intensive care unit admission and intubation following exposure to concentrated products. Conclusions: Neurotoxicity is common after acute cannabis exposures. Children experienced unintentional exposures, particularly within the home and occasionally with major adverse outcomes. Concentrated products such as resins and liquid concentrates were associated with greater toxicity than other cannabis products. These findings may help guide other states during the early retail cannabis legalization period.

CONTEXT: Mercury exposure has been described among small-scale gold mining communities in developing countries, but reports of inhalational mercury toxicity among home gold extractors in the US remain uncommon. OBJECTIVE: We sought to identify inhalational mercury exposures and toxicity among artisanal gold extractors. METHODS: This is an observational case series of a single Poison Center database from 2002-2015. We review all cases of "mercury" or "mercury inhalation" exposures, with detailed description of a recent representative case. RESULTS: Nine cases were reported, with patients' ages ranging 32-81 years. Eight (89%) patients were male. Seven of eight (88%) patients with acute exposures reported pulmonary symptoms consistent with mercury vapor inhalation such as dyspnea and cough; two (29%) patients had severe toxicity requiring intubation. Four of six (67%) patients had markedly elevated whole blood mercury concentrations up to 346 mcg/L; each received a different chelation regimen. Four (44%) patients used methamphetamines at the time of their exposure. The case report describes a patient with elevated mercury concentrations who required intubation for hypoxic respiratory failure. He received chelation therapy based on chelator availability, with decreasing 24-hour urine mercury concentrations. The house where he was exposed remains uninhabitable from elevated ambient mercury vapor concentrations. CONCLUSION: Artisanal gold extraction may be associated with inhalational mercury toxicity, including elevated blood mercury concentrations and acute hypoxic lung injury requiring intubation.

Pain is highly prevalent in health care settings; however, disparities continue to exist in pain care treatment. Few studies have investigated if differences exist based on patient-related characteristics associated with aging. The objective of this study was to determine if there are differences in acute pain care for older vs younger patients. This was a multicenter, retrospective, cross-sectional observation study of 5 emergency departments across the United States evaluating the 2 most commonly presenting pain conditions for older adults, abdominal and fracture pain. Multivariable adjusted hierarchical modeling was completed. A total of 6,948 visits were reviewed. Older (⩾ 65 years) and oldest (⩾ 85 years) were less likely to receive analgesics compared to younger patients (<65 years), yet older patients had greater reductions in final pain scores. When evaluating pain treatment and final pain scores, differences appeared to be based on type of pain. Older patients with abdominal pain were less likely to receive pain medications, while older patients with fracture were more likely to receive analgesics and opioids compared to younger patients. Differences in pain care for older patients appear to be driven by the type of presenting pain.
