RESUMO
This is a case report of a 19-month-old female who presented to the emergency department in cardiac arrest after methamphetamine exposure. Prior to presentation, she had seizure-like activity and then became unresponsive. On arrival, she had dilated pupils, intermittent clonus, and pulseless electrical activity. She was found to have full thickness circumferential burns of her bilateral lower extremities. She received 12 doses of epinephrine, cardiopulmonary resuscitation, and volume resuscitation after which she had return of spontaneous circulation and was transferred to the intensive care unit on an epinephrine drip. Initial laboratory studies showed a mixed metabolic and respiratory acidosis and hyperglycemia. An initial urine immunoassay for drugs of abuse was negative, however, 5 h later, a second urine immunoassay was positive for amphetamine. The first specimen was also sent for liquid chromatography-mass spectrometry analysis that later returned positive for methamphetamine and amphetamine. In retrospect, the initial urine screen was found to have evidence of amphetamine below the threshold for positivity (500 ng/mL), and the second urine specimen was highly positive, with an amphetamine level of >1450 ng/mL. In this case, what turned out to be a sub-threshold rather than undetectable level was clinically significant, highlighting the challenges of urine screening in cases of suspected poisoning syndromes with atypical presentations. Our case also suggests the possibility of PEA as a presentation of methamphetamine toxicity in a child.

Ethanol intoxication of infants and young children can be a challenging diagnosis in the pediatric emergency department, and features of the poisoning may differ in comparison with adolescents. The sources of ethanol exposures in this age are varied and include unintentional, malicious, and iatrogenic etiologies. Young children exposed to ethanol often present with mixed clinical signs and symptoms that may not fit the traditional ethanol or sedative-hypnotic toxidrome. Pediatric ethanol intoxications are often managed supportively, and recovery is usually rapid. The purpose of this review is to describe the sources of ethanol poisoning among children 6 years and younger, highlight presenting symptoms and pharmacokinetic considerations unique to this age group, and review management strategies. In addition, published cases of ethanol poisoning due to ingestion among young infants are compiled for presentation.

In December 2011 and December 2013, the Philadelphia Department of Public Health (PDPH) received separate reports of clusters of photokeratitis linked to gymnasium events. Photokeratitis, a painful eye condition resulting from unprotected exposure to ultraviolet radiation, has previously been linked to metal halide lamps with broken outer envelopes (1,2). To investigate the cause of these clusters and further characterize patients with photokeratitis, PDPH administered questionnaires to potentially exposed persons, established a case definition, and conducted environmental assessments of both gymnasiums. Because event attendee registration information was available, a cohort study was conducted to evaluate the 2011 cluster of 242 persons who met the photokeratitis case definition. A case-series investigation was conducted to evaluate the 2013 cluster of 20 persons who met the photokeratitis case definition for that event. These investigations indicated that Type R metal halide bulbs with broken outer envelopes found in both gymnasiums were the probable cause of the photokeratitis. The Food and Drug Administration has made a number of recommendations regarding the use of metal halide bulbs in facilities where bulbs are at elevated risk for breaking, such as schools and indoor sports facilities (3). Because Type R metal halide lamps do not self-extinguish once the outer envelope is broken, these bulbs should be removed from settings with a high risk for outer envelope rupture, such as gymnasiums, or should be placed within enclosed fixtures. In instances where these bulbs cannot be exchanged for self-extinguishing lamps, Type R lamps with a broken outer envelope should be replaced immediately to limit exposure to ultraviolet radiation. A broken outer envelope can be detected by the presence of glass on the floor, or visual examination of the bulb when the power is turned off. A broken outer envelope is difficult to detect when the lamp is emitting light.

BACKGROUND AND OBJECTIVES: Fatal poisoning is a preventable cause of death among young children. Understanding factors surrounding these deaths will inform future prevention efforts. Our objective was to describe the characteristics of fatal pediatric poisonings using child death review data. METHODS: We acquired data from 40 states participating in the National Fatality Review-Case Reporting System on deaths attributed to poisonings among children aged ≤5 years from 2005 to 2018. We analyzed select demographic, supervisor, death investigation, and substance-related variables using descriptive statistics. RESULTS: During the study period, 731 poisoning-related fatalities were reported by child death reviews to the National Fatality Review-Case Reporting System. Over two-fifths (42.1%, 308 of 731) occurred among infants aged <1 year, and most fatalities (65.1%, 444 of 682) occurred in the child's home. One-sixth of children (97 of 581) had an open child protective services case at time of death. Nearly one-third (32.2%, 203 of 631) of children were supervised by an individual other than the biological parent. Opioids (47.3%, 346 of 731) were the most common substance contributing to death, followed by over-the-counter pain, cold, and allergy medications (14.8%, 108 of 731). Opioids accounted for 24.1% (7 of 29) of the substances contributing to deaths in 2005 compared with 52.2% (24 of 46) in 2018. CONCLUSIONS: Opioids were the most common substances contributing to fatal poisonings among young children. Over-the-counter medications continue to account for pediatric fatalities even after regulatory changes. These data highlight the importance of tailored prevention measures to further reduce fatal child poisonings.

BACKGROUND: Case studies and small series have demonstrated that beverage ethanol may pose a serious poisoning hazard to infants. Intoxicated infants may not present with the classic signs or symptoms of ethanol poisoning. The objective of this study was to describe the epidemiology of beverage ethanol exposures among infants reported to the United States poison control centers. METHODS: Data from the National Poison Data System were retrospectively analyzed for infants <12 months of age who were exposed to beverage ethanol from 2009-2018. RESULTS: Over the 10-year study period, 1,818 infant exposures to beverage ethanol were reported. Most exposures were single substance (95.2%), and the most common route of exposure was ingestion (n = 1,738). Infants 9-11 months were the most commonly exposed age group subset (45.3%). The annual number and rate of alcoholic beverage exposure increased by 37.5% and 42.9%, respectively, from 2009 to 2018. Of the 563 infants evaluated at a healthcare facility, 38% of exposures were hospitalized. Infants 0-5 months of age had higher odds of being admitted to a non-critical (OR: 2.35, 95% CI: 1.41-3.92) or critical care unit (OR: 2.39; 95% CI: 1.50-3.79) compared to infants 6-11 months of age. Infants 0-5 months of age were more likely to (OR: 4.65; 95% CI: 3.18-6.79) experience a serious outcome compared to infants ages 6-11 months. Five fatalities in infants <6 months old were documented. An in-depth case review identified improper storage and subsequent formula preparation with beverage ethanol as a common exposure mechanism. CONCLUSIONS: Beverage ethanol exposures among infants are associated with hospitalization, serious clinical effects, and mortality. Infants may present with atypical signs and symptoms of intoxication, requiring a high index of suspicion. Opportunities exist to reduce exposures by addressing improper storage of beverage alcohols.

Exotic snakebites (i.e. from non-native species) are a rare occurrence, but they present a unique challenge to clinicians treating these patients. Poison control centers are often contacted to assist in the management and care of these medical emergencies. In this study, we analyzed case records of the two Pennsylvania poison control centers from 2004 to 2018 to describe clinical features reported as a result of exotic snakebite envenomation. For the 15-year period reviewed, 18 exotic snakebites were reported with effects ranging from mild local tissue injury to patients who were treated with mechanical ventilation due to respiratory failure. The mean age of the patients was 35 years and males accounted for 83% of the cases. Antivenom, the only specific treatment, was administered in seven of 18 patients within an average of four h of envenomation. The procurement of antivenom against these exotic species may require substantial logistical efforts due to limited stocking of this rarely used treatment. Newer, targeted, small molecule treatments that are being currently investigated may aid in the treatment of snakebites in general. However, people should be cautious when handling these exotic species, and clinicians should be aware of these bites and relevant clinical effects in order to manage these when reported.

Animal studies show efficacy of intravenous lipid emulsion in the treatment of severe cardiotoxicity associated with local anesthetics, clomipramine, and verapamil, possibly by trapping such lipophilic drugs in an expanded plasma lipid compartment ("lipid sink"). Recent case reports describe lipid infusion for the successful treatment of refractory cardiac arrest caused by parenteral administration of local anesthetics, but clinical evidence has been lacking for lipid's antidotal efficacy on toxicity caused by ingested medications. A 17-year-old girl developed seizure activity and cardiovascular collapse after intentional ingestion of up to 7.95 g of bupropion and 4 g of lamotrigine. Standard cardiopulmonary resuscitation for 70 minutes was unsuccessful in restoring sustained circulation. A 100-mL intravenous bolus of 20% lipid emulsion was then administered, and after 1 minute an effective sustained pulse was observed. The patient subsequently manifested significant acute lung injury but had rapid improvement in cardiovascular status and recovered, with near-normal neurologic function. Serum bupropion levels before and after lipid infusion paralleled triglyceride levels. This patient developed cardiovascular collapse because of intentional, oral overdose of bupropion and lamotrigine that was initially refractory to standard resuscitation measures. An infusion of lipid emulsion was followed rapidly by restoration of effective circulation. Toxicologic studies are consistent with the lipid sink theory of antidotal efficacy.

Niacin (vitamin B3) is promoted for rapidly clearing the body of drugs of abuse, such as cocaine and cannabis, and is alleged to interfere with urine drug screening. We present 4 cases of such novel use associated with significant adverse effects. Two cases had isolated skin manifestations, whereas the other 2 presented with life-threatening manifestations, including nausea, vomiting, dizziness, hepatotoxicity, metabolic acidosis, and hypoglycemia evolving into hyperglycemia. One patient also had profound neutrophilia and QT(C)-interval prolongation. All patients improved after cessation of the drug use and supportive treatment. Health care providers should be aware of these potential adverse effects of niacin and of the misguided use of this vitamin by patients seeking to interfere with urine drug screening.

CONTEXT: Our poison control center observed a large increase in the cost of many antidotes over the past several years. The high cost of antidotes has previously been cited as a factor leading to inadequate antidote supply at some hospitals. Continued increases in the cost of antidotes may lead to further reductions in antidote supply and represent serious concerns. This research aims to quantify recent trends in the costs of antidotes in the U.S. METHODS: Antidotes and minimum stocking recommendations were retrieved from published guidelines. RED BOOK Online® was used to identify the U.S. average wholesale price (AWP) of each antidote in 2010 and 2015. The AWP in 2010 was adjusted using the U.S. Consumer Price Index to adjust for inflation. The cost of minimum stocking levels for each antidote was calculated and compared between the year 2010 and 2015. RESULTS: The cost of stocking many antidotes demonstrated a large increase in AWP from 2010 to 2015. Of the antidotes evaluated, 15 out of 33 had greater than 50% increase in AWP and 8 out of 33 had greater than $1000 increase in AWP. Only four antidotes demonstrated decreases in AWP greater than 10% and only one antidote had its cost of stocking decrease in AWP by more than $1000. DISCUSSION: The price increase over the last 5 years may further hinder the willingness of hospitals to stock recommended antidotes at adequate quantities. This may impede timely treatment of patients, and negatively impact poisoning outcomes. CONCLUSIONS: The price of many antidotes substantially increased in the United States from 2010 to 2015. Strategies should be investigated to help decrease the cost associated with stocking and use of antidotes, including dose rounding, consignment, and regional sharing.

Antidotal therapy can be lifesaving in the management of poisoned children. Although supportive care is sufficient in many cases, a specific antidote can significantly reduce morbidity and mortality in a number of poisoning scenarios, and so the pediatric emergency medicine practitioner must be familiar with its indications for use, dosage and administration, and contraindications. A number of new antidotes have emerged in recent years. This review discusses the pediatric uses and limitations of intravenous N-acetylcysteine, octreotide, crotaline Fab antivenom, fomepizole, atropine and pralidoxime autoinjectors and provides some brief discussion on newer antidotes for which data is only starting to emerge.
