Acute Pediatric Liquid Nicotine Ingestions.

Electronic cigarette and vaping device use in the household represents a possible source of unintentional nicotine exposure to pediatric patients. Although most ingestions of nicotine may be mild, there is a potential for significant toxicity. Nicotine toxicity can present similarly to many other types of ingestions, which makes the history an important piece of the encounter. Treatment of nicotine toxicity is primarily supportive care directed at the presenting signs and symptoms. There is no antidotal therapy for nicotine toxicity. This review covers information that can assist clinicians who might treat a pediatric patient presenting with significant nicotine toxicity after the accidental ingestion of liquid nicotine products.

Pediatric Edible Cannabis Exposures and Acute Toxicity: 2017-2021.

OBJECTIVES: This study evaluates trends in pediatric cannabis edible ingestions in children younger than age 6 years with regard to toxicity, medical outcome, and health care utilization for the years 2017-2021. METHODS: We performed retrospective analysis of the National Poison Data System data for pediatric exposures to edible cannabis products in children <6 years from 2017 to 2021. Data were analyzed quantitatively with a focus on incidence, common clinical effects, medical outcomes, health care utilization, and changes in acute toxicity between the pre-COVID years (2017-2019) to the COVID years (2020-2021). RESULTS: There were 7043 exposures reported during 2017-2021. In 2017, there were 207 reported cases, and in 2021 there were 3054 cases, an increase of 1375.0%. Most exposures (97.7%) occurred in a residential setting. Seventy percent of cases followed to a known outcome were reported to have central nervous system depression. Of all reported cases, 22.7% of patients were admitted to the hospital. There was a significant increase in both ICU and non-ICU admissions, whereas the number of patients treated and released decreased when comparing the pre-COVID years (2017-2019) to the COVID years (2020-2021) (P < .05). Major and moderate effects also significantly increased during the prepandemic years compared with the 2 years during the pandemic (P < .05). CONCLUSIONS: There has been a consistent increase in pediatric edible cannabis exposures over the past 5 years, with the potential for significant toxicity. It is important for providers to be aware of this in their practice and it presents an important opportunity for education and prevention.

Predictors of severe outcome following opioid intoxication in children.

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.

Rising incidence and high mortality in intentional sodium nitrite exposures reported to US poison centers.

INTRODUCTION: Sodium nitrite is an oxidizing agent capable of producing profound methemoglobinemia. Large quantities of sodium nitrite can be purchased online, and recent literature has identified several cases of intentional self-poisoning, including multiple cases of mortality. This has raised concern that intentional sodium nitrite poisoning and resultant severe methemoglobinemia may be increasing in incidence and could represent a substantial public health threat. MATERIALS AND METHODS: This study used data obtained from the National Poison Data System (NPDS) to evaluate the incidence and mortality rate of intentional sodium nitrite poisoning of suicidal intent reported to US poison centers over a five-year period. Patient demographics, exposure characteristics, treatments administered, and patient outcomes were analyzed. Temporal patterns in exposure were also investigated. RESULTS: Forty-seven cases were identified in the NPDS database, of which three were excluded due to lack of outcome data. Median patient age was 23 years, 52% of patients were female and 86% of exposures occurred at the patient's residence. Serious outcomes were observed in 84% of cases, 77% of patients included were treated with methylene blue and 30% of patients died. No intentional sodium nitrite exposures were reported in the first two years studied, but we observed an increase in the incidence of exposures reported through the remainder of the investigation period. DISCUSSION/CONCLUSIONS: The incidence of intentional self-poisoning with sodium nitrite has been increasing since 2017. Many of these exposures result in toxicity requiring antidotal therapy, and a high mortality rate was observed. Recent literature indicates that this trend may be the result of ready access to this poison through online vendors combined with recommendations shared in online communities that sodium nitrite be used as an effective method of suicide. Further study is needed to better characterize this phenomenon and develop public health interventions to prevent future morbidity and mortality.
