RESUMO
INTRODUCTION: An increasing number of jurisdictions have legalized recreational cannabis for adult use. The subsequent availability and marketing of recreational cannabis has led to a parallel increase in rates and severity of pediatric cannabis intoxications. We explored predictors of severe outcomes in pediatric patients who presented to the emergency department with cannabis intoxication. METHODS: In this prospective cohort study, we collected data on all pediatric patients (<18 years) who presented with cannabis intoxication from August 2017 through June 2020 to participating sites in the Toxicology Investigators Consortium. In cases that involved polysubstance exposure, patients were included if cannabis was a significant contributing agent. The primary outcome was a composite severe outcome endpoint, defined as an intensive care unit admission or in-hospital death. Covariates included relevant sociodemographic and exposure characteristics. RESULTS: One hundred and thirty-eight pediatric patients (54% males, median age 14.0 years, interquartile range 3.7-16.0) presented to a participating emergency department with cannabis intoxication. Fifty-two patients (38%) were admitted to an intensive care unit, including one patient who died. In the multivariable logistic regression analysis, polysubstance ingestion (adjusted odds ratio = 16.3; 95% confidence interval: 4.6-58.3; P < 0.001)) and cannabis edibles ingestion (adjusted odds ratio = 5.5; 95% confidence interval: 1.9-15.9; P = 0.001) were strong independent predictors of severe outcome. In an age-stratified regression analysis, in children older than >10 years, only polysubstance abuse remained an independent predictor for the severe outcome (adjusted odds ratio 37.1; 95% confidence interval: 6.2-221.2; P < 0.001). As all children 10 years and younger ingested edibles, a dedicated multivariable analysis could not be performed (unadjusted odds ratio 3.3; 95% confidence interval: 1.6-6.7). CONCLUSIONS: Severe outcomes occurred for different reasons and were largely associated with the patient's age. Young children, all of whom were exposed to edibles, were at higher risk of severe outcomes. Teenagers with severe outcomes were frequently involved in polysubstance exposure, while psychosocial factors may have played a role.

INTRODUCTION: While the opioid crisis has claimed the lives of nearly 500,000 in the U.S. over the past two decades, and pediatric cases of opioid intoxications are increasing, only sparse data exist regarding risk factors for severe outcome in children following an opioid intoxication. We explore predictors of severe outcome (i.e., intensive care unit [ICU] admission or in-hospital death) in children who presented to the Emergency Department with an opioid intoxication. METHODS: In this prospective cohort study we collected data on all children (0-18 years) who presented with an opioid intoxication to the 50 medical centers in the US and two international centers affiliated with the Toxicology Investigators Consortium (ToxIC) of the American College of Medical Toxicology, from August 2017 through June 2020, and who received a bedside consultation by a medical toxicologist. We collected relevant demographic, clinical, management, disposition, and outcome data, and we conducted a multivariable logistic regression analysis to explore predictors of severe outcome. The primary outcome was a composite severe outcome endpoint, defined as ICU admission or in-hospital death. Covariates included sociodemographic, exposure and clinical characteristics. RESULTS: Of the 165 (87 females, 52.7%) children with an opioid intoxication, 89 (53.9%) were admitted to ICU or died during hospitalization, and 76 did not meet these criteria. Seventy-four (44.8%) children were exposed to opioids prescribed to family members. Fentanyl exposure (adjusted OR [aOR] = 3.6, 95% CI: 1.0-11.6; p = 0.03) and age ≥10 years (aOR = 2.5, 95% CI: 1.2-4.8; p = 0.01) were independent predictors of severe outcome. CONCLUSIONS: Children with an opioid toxicity that have been exposed to fentanyl and those aged ≥10 years had 3.6 and 2.5 higher odds of ICU admission or death, respectively, than those without these characteristics. Prevention efforts should target these risk factors to mitigate poor outcomes in children with an opioid intoxication.

This article aimed to determine the association between the Affordable Care Act young adult mandate and suicidal behavior. From 2007 to 2013, we used the Nationwide/National Inpatient Sample and National Poison Data System to examine suicide attempt, and Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research to examine suicide. We aggregated each outcome by quarter/year and conducted a difference-in-differences linear regression to compare young adults aged 19 to 25 years with those 27 to 29 years before and after implementation. There were not statistically significant associations between the mandate and suicide attempt inpatient hospitalizations (unstandardized beta coefficient [b] = -0.72, p = .12, standard error [SE] = 0.42) and percentage of poisoning cases due to suspected suicidal intent (b = 0.23, p = .19, SE = 0.16). There was a statistically significant association when examining suicide prevalence (b = -0.03, p = .01, SE = 0.001). The results suggest that health insurance may buffer against but is unlikely to reverse the increasing suicide rate.

OBJECTIVES: Adolescent depression and attempted and completed suicide are increasing in the United States. Because suicide is often impulsive, the means of self-harm are frequently items of convenience like medication. Authors of a recent study compared tricyclic antidepressant overdose to bupropion overdose. Fluoxetine and escitalopram are the only agents with Food and Drug Administration approval for pediatric depression, but off-label bupropion prescriptions are common. We sought to compare the effects of selective serotonin reuptake inhibitors (SSRIs) and bupropion in overdose. METHODS: This was an analysis of the National Poison Data System from June 2013 through December 2017 for adolescent (ages 10-19) exposures to SSRIs or bupropion coded as "suspected suicide." Demographics, clinical effects, therapies, and medical outcome were analyzed. RESULTS: There were 30 026 cases during the study period. Sertraline and fluoxetine accounted for nearly 60%, whereas bupropion was reported in 11.7%. Bupropion exposure was significantly associated with death (0.23% vs 0%; P < .001) or serious outcome (58.1% vs 19%; P < .001) as well as the 10 most common clinical effects, including seizures (27.0% vs 8.5%; P < .001) and hallucinations (28.6% vs 4.3%; P < .001). Bupropion exposure was significantly associated with the need for cardiopulmonary resuscitation (0.51% vs 0.01%; P < .001), intubation (4.9% vs 0.3%; P < .001), vasopressors (1.1% vs 0.2%; P < .001), and benzodiazepines (34.2% vs 5.5%; P < .001). There was a significant increase in all exposures and in proportion of serious outcomes over time. CONCLUSIONS: Adolescents who attempt self-harm are at higher risk for serious morbidity and poor outcomes with bupropion than with SSRIs. These risks, and the patient's propensity for self-harm, should be evaluated when therapy with bupropion is considered.

Background: In the United States, adolescent suicide attempts are increasing. Indiana has the highest rate of adolescent suicidal ideation in the US. Using the National Poison Data System (NPDS), we analyzed Indiana's increase in suicide attempts by poisoning. Methods: Utilizing NPDS and Toxicall data repositories, we selected 10-19 year-old intentional overdose cases with suspected suicidal intent from 2006-2016. Age, sex, outcome, involved substances and case volume by weekday and month were assessed. Geospatial analysis of the proportion of cases by county was also performed. To determine the association between known social determinants of health and adolescent intentional overdose cases with suspected suicidal intent, we correlated county-wide statistics from the County Health Rankings and Roadmaps dataset from 2010-2016 with the proportion of teen suicide cases by county. Results: Over the eleven years, adolescent intentional overdoses with suspected suicidal intent cases significantly increased starting in 2012 (p-value < .001). The majority of cases (73.7%) involved females with an average age of 15.96 ± 0.27 years. Monday and Tuesday had the highest rates and Saturday had the lowest. June and July had the lowest case rate while November had the highest. The most commonly involved agents were over-the-counter analgesics and antidepressants. Geospatial analysis shows an increased number of cases in the northern third of the State. Among county statistics analyzed, only violent crime was associated, albeit intermittently, with the 11-year proportion of adolescent intentional overdoses with suspected suicidal intent by county. Conclusions: Intentional overdoses with suspected suicidal intent involving adolescent females are significantly increasing. These rates correlate with the school schedule with summer months and weekends having a lower frequency of calls. We did not find associations between county wide social determinants of care with the exception of violent crime. Further studies are needed to establish the factors that might better predict adolescents at risk for suicide.

The use of ketamine as a drug of abuse has increased and so too has the risk of accidental overdose. Here, the authors report the case of a 10-month-old infant who inadvertently ingested ketamine. The child demonstrated severe cerebellar swelling that required emergency surgical intervention. The authors describe the clinical course of this child and present the radiographic characteristics of the brain. The imaging characteristics were not consistent with purely anoxic injury, thus suggesting a specific effect of this drug. To the authors' knowledge, similar imaging characteristics in this context have not been described.

BACKGROUND: Vilazodone is a selective serotonin reuptake inhibitor and 5HT1A agonist recently approved to treat depression in adults. To date, there are minimal data available regarding the expected course and treatment of acute vilazodone ingestions. CASE REPORT: We report a case of a previously healthy 19-month-old girl who presented after an acute ingestion of an estimated 37 mg/kg vilazodone. She was taken to an outside emergency department approximately 1 h after an unwitnessed ingestion. Initially, the patient was noted to have decreased responsiveness, sluggish but reactive pupils, altered mental status, and reported seizure activity. She was given intravenous lorazepam for seizure control, intubated, and transferred to a pediatric tertiary care facility, where she continued to show signs of serotonin toxicity and received treatment with benzodiazepines and cyproheptadine. Despite vilazodone's long half-life and the large amount ingested, the patient was extubated within 10 h of presentation, had returned to baseline mental status by 22 h, and was discharged home approximately 57 h after ingestion. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Accidental ingestions are common in the pediatric population. Emergency physicians need to be aware of the signs and symptoms of acute medication toxicities, the expected clinical course, and the necessary supportive measures used to treat these patients. Because vilazodone is a recently approved medication, there is little experience with acute vilazodone ingestions. This report considerably increases the understanding of vilazodone's effects in the setting of an acute ingestion.

The objective of this study was to characterize the acute clinical effects, laboratory findings, complications, and disposition of patients presenting to the hospital after abusing synthetic cathinone. We conducted a retrospective multicenter case series of patients with synthetic cathinone abuse by searching for the terms bath salts, MDPV, methylenedioxypyrovalerone, mephedrone, methcathinone, methylone, methedrone, and cathinone within the "agent" field of a national clinical toxicology database (ToxIC). The medical records of these patients were obtained and abstracted by investigators at each study site. Patients with confirmatory testing that identified a synthetic cathinone in either blood or urine were included in the series. Patients who had either an undetectable synthetic cathinone test or no confirmatory testing were excluded. A data abstraction sheet was used to obtain information on each patient. We entered data into an Excel spreadsheet and calculated descriptive statistics. We identified 23 patients with confirmed synthetic cathinone exposure--all were positive for methylenedioxyprovalerone (MDPV). Eighty-three percent were male and 74 % had recreational intent. The most common reported clinical effects were tachycardia (74 %), agitation (65 %), and sympathomimetic syndrome (65 %). Acidosis was the most common laboratory abnormality (43 %). Seventy-eight percent of patients were treated with benzodiazepines and 30 % were intubated. Ninety-six percent of patients were hospitalized and 87 % were admitted to the ICU. The majority (61 %) of patients was discharged home but 30 % required inpatient psychiatric care. There was one death in our series. The majority of patients presenting to the hospital after abusing MDPV have severe sympathomimetic findings requiring hospitalization. A number of these patients require inpatient psychiatric care after their acute presentation.

OBJECTIVES: The objective was to ascertain whether acetaminophen (APAP) concentrations less than 100 µg/mL obtained between 1 and 4 hours after acute ingestion accurately predict a nontoxic 4-hour concentration. METHODS: The authors performed a multicenter, prospective cohort study involving five emergency departments (EDs) participating in the ToxIC Research Network. Data were collected from May 2009 to December 2011. Patients with APAP concentrations <100 µg/mL drawn between 1 and 4 hours after acute ingestions, and concentrations drawn 4 or more hours after ingestions, were included in the study. Exclusion criteria included initial concentration >100 µg/mL, initial APAP concentration drawn prior to 1 hour, two undetectable APAP concentrations, the second concentration drawn prior to 4 hours, and unknown time of ingestion. Toxic concentrations 4 or more hours after ingestion were defined as concentrations that plotted above the 150 µg/mL line on the Rumack-Matthew nomogram. RESULTS: Data were collected on 83 patients who met inclusion criteria. Of the 83 patients with APAP concentrations <100 µg/mL between 1 and 4 hours, one patient (1.2%) had a ≥ 4-hour toxic concentration. Negative predictive value (NPV) for an APAP concentration <100 µg/mL obtained between 1 and 4 hours after an acute ingestion was 98.8% (95% confidence interval [CI] = 93.5% to 99.8%). CONCLUSIONS: An APAP concentration of <100 µg/mL obtained between 1 and 4 hours after ingestion has a high NPV for excluding toxic ingestion. We do not recommend reliance on concentrations obtained between 1 and 4 hours to exclude toxicity, because of a potential false-negative rate of 6.5%.

UNLABELLED: Oral and intravenous (IV) N-acetylcysteine (NAC) are used for the treatment of acetaminophen poisoning. The objective of this multicenter study was to compare the safety of these two routes of administration. METHODS: We conducted a multicenter chart review of all patients treated with NAC for acetaminophen poisoning. The primary safety outcome was the percentage of patients with NAC-related adverse events. RESULTS: A total of 503 subjects were included in the safety analysis (306 IV-only, 145 oral-only, and 52 both routes). There were no serious adverse events related to NAC for either route. Nausea and vomiting were the most common related adverse events and were more common with oral treatment (23 vs. 9%). Anaphylactoid reactions were more common with IV administration (6 vs. 2%). CONCLUSIONS: IV and oral NAC are generally mild adverse drug reactions.

Of the known elements, nearly 80% are either metals or metalloids. The highly reactive nature of most metals result in their forming complexes with other compounds such oxygen, sulfide and chloride. Although this reactivity is the primary means by which they are toxic, many metals, in trace amounts, are vital to normal physiological processes; examples include iron in oxygen transport, manganese and selenium in antioxidant defense and zinc in metabolism. With these essential metals toxicity occurs when concentrations are either too low or too high. For some metals there are no physiological concentrations that are beneficial; as such these metals only have the potential to cause toxicity. This chapter focuses on four of these: arsenic, mercury, lead and thallium.

Each year over 100,000 exposures to toxic plants are reported to poison centers throughout the United States. Most of these exposures are of minimal toxicity largely because of the fact that they involve pediatric ingestions, which are of low quantity. The more serious poisonings usually involve adults who have either mistaken a plant as edible or have deliberately ingested the plant to derive perceived medicinal or toxic properties. The plants within this manuscript have been chosen because they have been documented to cause fatalities or account for emergency medicine visits. In this discussion, plants are grouped by their toxins rather than on the basis of their taxonomy.

Humans have had a long and tumultuous relationship with heavy metals. Their ubiquitous nature and our reliance on them for manufacturing have resulted at times in exposures sufficient to cause systemic toxicity. Their easy acquisition and potent toxicity have also made them popular choices for criminal poisonings. This article examines the clinical manifestation and pathophysiology of poisoning from lead, mercury, arsenic, and thallium.
