RESUMO
INTRODUCTION: Aquatic envenomations are common injuries along the coastal United States that pose a public health risk and can cause significant morbidity. We examined aquatic envenomation exposures that were called in to poison control centers (PCC) in the United States from 2011 to 2020. METHODS: The Association of Poison Control Center's (AAPCC) National Poison Data System was queried for all aquatic envenomations reported during the 10 y period from January 1, 2011, to December 31, 2020. Data collected included date, exposure and geographic location, patient age and sex, signs and symptoms, management setting, treatments, and clinical outcome. Duplicated records, confirmed nonexposure, and reports not originating within the United States were excluded. RESULTS: There were 8517 human aquatic envenomations reported during the study period, 62% (5243) of whom were male; 56% (4264) of patients were 30 y or younger. There were an average of 852 calls per year, with 46% of calls occurring during June to August. California, Texas, and Florida had the highest number of envenomations during the study period. Fish (61%; 5159) and Cnidaria (30%; 2519) envenomations were the most common exposures. Overall, 37% (3151) of exposures were treated in healthcare facilities, with no deaths reported. CONCLUSIONS: The highest proportion of aquatic envenomations occurred among younger males (≤30 y) during the summer months. While rarely leading to major adverse events, aquatic envenomations were commonly reported injuries to PCC and occurred in all 50 states. Poison control centers continue to be real-time sources of information and data regarding aquatic envenomation trends.

BACKGROUND AND OBJECTIVES: Capecitabine is an oral prodrug of 5-fluorouracil. Toxicity can occur during therapy as well as acutely with overdose and particular genetic susceptibilities. Uridine triacetate is an effective antidote if given within 96 h of exposure. This study seeks to characterize accidental and intentional capecitabine exposures and uridine triacetate use, about which little has been published. METHODS: A retrospective review of capecitabine exposures from 30 April 2001 to 31 December 2021 reported to a statewide poison control center was performed. All single-substance oral exposures were included. RESULTS: In total, 81 of 128 reviewed cases were included, with a median age of 63 years. In total, 49 were acute-on-chronic exposures and 32 were acute exposures in capecitabine-naïve patients, 29 of which were accidental. Fifty-six (69%) were managed at home. Of these, none later recontacted the poison control center to report symptoms or were known to have later had healthcare facility evaluations. Of the 25 cases presenting for healthcare facility evaluation, 4 were acutely symptomatic. Thirteen were eligible for uridine triacetate, and six received it; no new or progressive toxicity was reported after. Three developed mild latent toxicity; otherwise, no morbidity or mortality was reported. CONCLUSIONS: Accidental acute-on-chronic and acute ingestions of capecitabine appear to be well tolerated; most cases were managed at home. Unfortunately, little is known regarding the threshold at which toxicity may present following exposures. The threshold may vary individually given genetic susceptibilities. Management was heterogeneous, likely reflecting inadequate guidelines. Further research is needed to better delineate at-risk populations and treatment strategies.

OBJECTIVES: Lithium is an uncommon pediatric exposure, and the effects of accidental or exploratory ingestions are not well characterized. This study examined the clinical effects and outcomes of unintentional lithium ingestions treated in a health care facility for patients up to 16 years old. METHODS: The database from a single-state Poison Control System was queried for all pediatric lithium exposures managed in a health care facility between January 2006 and December 2021. Inclusion criteria were 16 years or younger and acute lithium exposure treated in a health care facility. Those older than 16 years, nonoral exposures, intentional, chronic, or nonlithium exposures, and out-of-state patients were excluded. RESULTS: One hundred eighteen cases were included, and 619 were excluded. The median age was 2 years (range, 0.5-15 years). One hundred fifteen (97%) were 7 years or younger. Sixty-eight (57.6%) were boys. One hundred thirteen (96%) were exploratory ingestions. Lithium carbonate was the most common formulation, with a median reported dose of 525 mg (range, 100-13,500 mg). Sixty-seven (57%) had serum lithium concentrations available: 19 (28%) were detectable (>0.1 mEq/L) and 4 were supratherapeutic (>1.2 mEq/L).One hundred (85%) patients were coded as having no effects. Four (3%) patients had coded effects-1 mild, 2 moderate, and 1 major; all were polydrug ingestions and recovered fully with basic supportive care. The loss to follow-up rate was 12%.A small minority received treatment with intravenous fluids and/or whole bowel irrigation. Thirteen (11%) were admitted, 3 to the ICU. No morbidity or mortality was reported. CONCLUSIONS: The majority of unintentional pediatric lithium ingestions examined were exploratory and resulted in no significant symptoms. Only a small minority had detectable serum lithium concentrations. All isolated lithium exposures were asymptomatic. Unintentional exposures appear to be benign, even with detectable lithium levels. Further study is needed to better risk stratify for home care versus health care facility evaluation.

Bromism is an unusual syndrome characterized by a variety of nervous system impairments such as ataxia, confusion, and delusions. Contemporaneous cases are rare as therapeutic use of bromide-containing medications has declined, but bromides can still be obtained as unregulated dietary supplements. Bromism from dietary supplements is not well-described. We present a case of a 23-year-old male who was taking numerous supplements and developed bromism, characterized by ataxia, confusion, and persistent agitation. His laboratory evaluation revealed a large negative anion gap and a serum bromide level of 1200 mg/L (ref: 0-12 mg/L). He was treated with maintenance intravenous normal saline to promote excretion of the bromide ion and slowly returned to baseline over ten days. Bromism is an unusual but well-described constellation of neurologic impairments that presents insidiously and may be easily missed. The emergency physician should be aware of the dangers of bromide-containing dietary supplements and should educate patients taking these supplements of their risks.

ABSTRACT: There is a paucity of published reports of copper ammonium complex ingestion, as most published data describe overdoses of copper sulfate formulations. We report a case of suicide by ingestion of copper ammonium complex-containing fungicide with an elevated postmortem copper level. A 77-year-old woman was found dead at home by her relative after ingesting a fungicide containing 8% copper ammonium complex solution. Turquoise emesis was found at the scene, and on autopsy, turquoise material was found throughout the gastrointestinal tract. Postmortem central blood copper level was 500 µg/dL. Cause of death was determined to be acute copper toxicity.

There is no pediatric overdose information available for perampanel. We present twocases involving children 2 years of age. A female ingested 0.77mg/kg perampanel anddeveloped drowsiness and ataxia within an hour, followed by bradycardia after 6 hours.She was admitted to the pediatric intensive care unit and given fluids and was thendischarged after 20 hours. The other case involved a male who ingested 0.25mg/kgperampanel and developed ataxia within an hour, eventually he was discharged after 6hour observation in the emergency department without any treatment.

Cerbera odollam or "pong-pong" tree contains cardiac glycosides similar to digoxin, oleander and yellow oleander. Cerbera odollam is a common method of suicide in South East Asia and has also been used as a weight loss supplement. We present a case of a 33-year-old female presenting with lethargy, vomiting, bradycardia, severe hyperkalemia of 8.9 mEq/L, slow atrial fibrillation followed by cardiovascular collapse following the ingestion of "pong-pong", the kernel of Cerbera odollam, as a weight loss supplement. Despite the administration of a total of nine vials of digoxin-specific Fab the patient could not be resuscitated. Clinicians should be aware of natural cardiac glycosides being uses as weight-loss agents and consider acute cardiac glycoside poisoning in patients with hyperkalemia, abnormal cardiovascular signs, symptoms and abnormal ECG findings.

BACKGROUND: Historically, anticoagulants and antiplatelet agents included warfarin and aspirin, respectively. In recent years, numerous novel anticoagulants (eg, direct thrombin inhibitors and factor Xa inhibitors) as well as the adenosine diphosphate receptor antagonists have increased significantly. Little information on the bleeding risk after exploratory ingestion of these agents is available. The primary purpose of this study is to evaluate the bleeding risk of these agents after an exploratory ingestion in children 6 years or younger. METHODS: This retrospective multicenter poison control center study was conducted on calls between 2005 and 2014. The following agents were included: apixaban, clopidogrel, dabigatran, edoxaban, prasugrel, rivaroxaban, or ticagrelor. Bleeding characteristics and treatment rendered were recorded. RESULTS: A total of 638 cases were identified. Most cases involved antiplatelet agents. No patient developed any bleeding complication. The administration of charcoal was independent of the amount of drug ingested. CONCLUSION: Accidental, exploratory ingestions of these agents seem well tolerated, with no patient developing bleeding complications.

BACKGROUND: Most Americans take at least one medication on a daily basis. Inadvertently ingesting a double-dose of a medication with a narrow therapeutic index may lead to adverse effects. When a patient or medical professional contacts the local poison center after an overdose, a poison specialist fields the incoming information and, depending on the caller, provides specific recommendations. We sought to determine which medication classes were most likely to lead to significant adverse outcomes when an extra dose was ingested. METHODS: This was a retrospective review of all double-dose medication ingestions reported to the California Poison Control System (CPCS) between January 2006 and December 2015. Inclusion criteria were single-instance, single-medication ingestions where the dose was known. All ages and both sexes were included. We evaluated generalized outcomes per AAPCC criteria stratified as no effect, minor, moderate, major or death. We also documented specific symptoms and interventions noted by the poison control specialists. RESULTS: Out of 1286 cases, 876 ingestions met the inclusion criteria. Medications with antihypertensive and behavior modulating effects each accounted for over a third of all moderate and major effects. The medications/medication classes implicated in the 12 major outcomes included propafenone, beta blockers (ßBs), calcium channel blockers (CCBs), bupropion, and tramadol. Of these, vasoactive medications were associated with the most severe effects requiring cardiac pacing and vasopressor drips. Analgesics, antimicrobials, and anti-allergy medications were well tolerated. There were no deaths. CONCLUSIONS: Major adverse outcomes after a double dose ingestion were rare. Most double dose medication ingestions can be safely monitored at home, albeit with a few exceptions. Vigilance is warranted in cases of ßB and CCB ingestion due to the risk of hemodynamic collapse or seizures with tramadol and bupropion.

INTRODUCTION: Cyanoacrylate (Super Glue®) exposures are commonly reported to poison control centers, but little has been published in the medical literature regarding these exposures. We sought to characterize cyanoacrylate exposures reported to a poison control system. METHODS: We performed a retrospective review of a poison system's database for all cases of single-substance human exposure to cyanoacrylate-containing products from 2005 to 2015. Data collected included age, gender, route of exposure, clinical effects, treatments recommended and medical outcome. RESULTS: There were a total of 893 patients, 505 (56.6%) of which were female. Patient ages ranged from 6 months to 88 years with a median of 11 years. The vast majority of exposures (n = 871, 97.5%) were unintentional, but a small number of exposures (n = 22, 2.5%) were due to intentional misuse (such as trying to stop a bleeding cut) or malicious intent (such as purposefully gluing a person's eyes shut as a prank). Routes of exposure included: ingestion, n = 337 (37.7%); ocular, n = 322 (36.1%); dermatologic, n = 285 (31.9%); inhalation, n = 16 (1.8%); nasal, n = 1 (0.1%); and otic, n = 1 (0.1%); some patients had multiple routes of exposure. Treatments recommended by the poison center included irrigation (n = 411), petroleum jelly (n = 143), mineral oil (n = 131), topical antibiotic ointment (n = 82), peanut butter (n = 6), acetone (n = 4) and WD-40® (n = 2). A total of 657 patients (73.6%) were managed on-site, while 236 (26.4%) were seen in a health care facility. Among all exposures, effects were classified as none (n = 287), minor (n = 529) and moderate (n = 77). No major effects or deaths were reported. CONCLUSIONS: In this case series, the majority of cases occurred in children and most exposures did not result in significant morbidity. Notably, there was wide variation in terms of recommended treatments; further study is needed to determine the optimal treatment method and to standardize poison center recommendations for treating patients with cyanoacrylate exposures.

We studied stingray stings reported to our poison system to identify associated complications and treatments. We undertook a 14-year retrospective observational analysis of stingray stings reported to our poison system. Extracted data included caller age and gender, outcome, management site, symptoms, treatments, and geographical location of the sting. We examined suspected infection rate, hot water treatment efficacy, and possible presence of foreign bodies in the wound. Suspected infection rate was defined as "possible infection" or "likely infection." Hot water treatment efficacy was defined as cases that encoded hot water as a treatment and noted pain relief within 1 hour of treatment in the free-text record, before documentation of other analgesic administration. A total of 576 envenomations were reported. The majority were men (76%), with an average age of 24 years (range, 6-78 years). Symptoms were reported in 485 cases. A total of 9% recorded a foreign body or debris at the wound site. Symptoms included pain (79%), puncture wound (65%), and edema (25%). Infections were reported in 9% of cases. Hot/warm water immersion appeared effective for pain relief in 69% of cases where outcome was documented. The most common geographical location of stingray envenomations was Southern California. Stingray stings are common in California. Hot/warm water seemed to be effective in pain management in our series, whereas foreign bodies or retained spines and infections were other identified complications.

BACKGROUND: Death due to prescription opioid exposure has increased dramatically in North America. Currently, there is a lack of literature detailing potentially lethal doses as well as postmortem tissue analysis concentrations from prescription opioid fatalities in children. We report a pediatric hydromorphone fatality with postmortem peripheral blood, central blood, liver, and gastric concentrations. CASE REPORT: A 3-year-old male was found unresponsive on a couch. Emergency services were contacted and responders found him pulseless, apneic, and asystolic. Resuscitative measures were unsuccessful and he was pronounced dead at a local hospital soon after arrival. Postmortem investigations revealed that two hydromorphone tablets (2 mg each) were missing. There was no demonstrable natural disease or traumatic injury to which to attribute his death upon autopsy; while postmortem concentrations of hydromorphone were confirmed and quantitated in peripheral blood at 0.03 mg/L, central blood 0.06 mg/L, and liver 0.10 mg/kg. CONCLUSION: Given the paucity of reported pediatric opioid-related fatalities, we describe a hydromorphonep-related death in a child, which includes postmortem hydromorphone concentrations.

STUDY OBJECTIVE: With the increasing amount of information available on the Internet describing techniques for using loperamide either for self-treatment of opioid withdrawal syndromes or for recreational use (so-called legal highs), the objective was to describe a statewide poison control system's experience with loperamide misuse and abuse, with specific interest in cases of cardiotoxicity, and to determine if reported loperamide misuse or abuse cases have recently increased. DESIGN: Retrospective review. DATA SOURCE: Statewide poison control system electronic database. PATIENTS: A total of 224 adults who presented or were referred to a health care facility between January 1, 2002, and November 10, 2015, for intentional ingestions of loperamide, and whose cases were reported to the poison control system by either physicians or nurses at the bedside. MEASUREMENTS AND MAIN RESULTS: Between 2002 and 2013, the number of yearly calls to the poison control system regarding loperamide cases ranged from 12-19 (mean 16.4, median 17.5 calls). In 2014, a sharp increase to 41 calls was noted. On completion of the study (November 10, 2015), 27 calls had been recorded. Medical outcomes of loperamide exposure for each patient were classified in accordance with the American Association of Poison Control Center's classification system as minor, moderate, or severe. For those patients with known outcomes, 3 resulted in death, 9 had major effects, 49 had moderate effects, and 36 had minor effects. We identified nine reports of patients who developed cardiotoxicity, with eight of them occurring between 2012 and 2015. A spike in the number of cases of loperamide toxicity reported in 2014 and 2015 coincided with an abundance of online instructions on how to abuse this drug. Almost all cases of recorded cardiotoxicity occurred over the last 3 years. Cardiotoxicity from loperamide abuse has only recently been recognized as a potential complication during the last few years, so earlier cases of cardiotoxicity resulting from loperamide abuse were likely missed. CONCLUSION: Our data suggest that loperamide may be increasing in popularity as a drug of abuse and for treatment of opioid withdrawal symptoms. Given the potential for significant toxicity with loperamide exposure, including life-threatening cardiac dysrhythmias, clinicians should consider obtaining a screening electrocardiogram for patients presenting after acute or chronic high-dose ingestions of loperamide. In addition, increased control over the availability of loperamide may be warranted.

Tapentadol (TAP) is an analgesic agent indicated for the management of different types of pain. It has a novel mechanism of action in that it induces analgesia via both µ-opioid receptor agonism and norepinephrine reuptake inhibition. Although deaths associated with TAP use have been reported, there is a paucity of published literature regarding TAP concentrations in biological samples obtained from TAP-associated fatalities. We report a case of TAP toxicity resulting in death with postmortem peripheral and central blood concentrations, liver, vitreous, urine, and gastric contents. A 41-year-old female was found slumped over a sink at home following a welfare check by police. She was transported to a local hospital where she was pronounced dead despite all resuscitative measures. The autopsy was remarkable only for pulmonary edema and signs of aspiration pneumonia. Postmortem concentrations of TAP were confirmed in peripheral blood at 1.1mg/L, central blood 1.3mg/L, liver 9.9mg/kg, vitreous humor 0.94mg/L, urine 88mg/L, and the gastric contained 2mg. Also of note, oxycodone was found in the decedent's blood at a concentration of 0.58mg/L. We report a death related to an intentional ingestion of TAP and oxycodone-the cause and manner of death were determined to be mixed drug intoxication; suicide. We hope that the variety of TAP concentrations identified in this case provide valuable points of reference for future cases of TAP intoxication.
