Preventing Pediatric Opioid Poisoning: Unusual Sources and Scenarios.

This retrospective study analyzed 230 pediatric opioid exposures from a statewide poison control center over a 5-year period. Most exposures involved pharmaceutical opioids and children below 2-years-old. Narrative details were reviewed to identify uncommon sources of opioids involved in poisoning and highlight the need for tailored prevention strategies and guidance.

Management patterns of multiple magnet ingestion reported to New Jersey Poison Information and Education System.

BACKGROUND: Ingestion of multiple high-powered neodymium rare-earth magnets poses a significant risk for gastrointestinal (GI) injury such as bowel perforation or ischemia. Given the rising incidence of rare earth magnetic ingestions and the corresponding increase in serious injuries in children, published guidelines recommend urgent endoscopic removal of all magnets within endoscopic reach in cases involving ingestions of two or more magnets. RESEARCH QUESTION: Do management patterns for multiple magnet ingestion align with current practice guidelines, and does hospital length of stay (LOS) differ based on the initial emergency department (ED) approach? METHODS: This is a retrospective chart review of consecutive patient encounters reported to the New Jersey Poison Information and Education System (NJPIES) between January 2021 and April 2022 involving multiple magnet ingestion. Potential cases were retrieved from the NJPIES TOXICALL® database, using substance codes relating to magnet or foreign body ingestion. Two-sample T tests were used to determine the statistical difference in the hospital LOS between the group of patients receiving early emergent esophagogastroduodenoscopy (EGD) versus those receiving expectant management on initial presentation. RESULTS: There was a difference in the average LOS of 2.7 days (p = 0.023) longer in the expectant management group with no medical complications in either group. Twenty-five percent or 2 out of 8 cases deviated from guidelines. CONCLUSION: The initial ED decision to pursue expectant management instead of attempting emergent EGD removal of magnets may result in prolonged hospitalization, increased risk for readmission, and delayed definitive removal of magnets due to nonprogression along the GI tract.

Lead encephalopathy presenting as status epilepticus: a case report.

BACKGROUND: Lead encephalopathy, while thankfully rare, is a devastating and potentially fatal consequence of lead intoxication. Owing to successful public health measures, severe lead toxicity is not often encountered by most practicing physicians in the United States, making both its recognition and management challenging. A case study of a 4-year-old female presenting in refractory status epilepticus, found to have severe microcytic anemia and lead level > 100 mcg/dL. CASE PRESENTATION: We report a case of a 4-year-old girl who presented with refractory seizures, severe microcytic anemia, and a history of developmental delay who was ultimately diagnosed with lead encephalopathy, requiring multiple courses of calcium disodium ethylenediaminetetraacetic acid (EDTA) and succimer for rebounding lead levels. CONCLUSION: Rapid recognition and appropriate management is essential to ensure neurologically intact survival. This case documents one of the first cases of successful lead chelation after multiple courses of calcium disodium EDTA and succimer dual therapy since the removal of dimercaprol from the United States market. This case also highlights the importance of using body surface area dosing for chelation therapy in order to prevent under-dosing in young children.

Extracorporeal Treatment for Gabapentin and Pregabalin Poisoning: Systematic Review and Recommendations From the EXTRIP Workgroup.

Toxicity from gabapentin and pregabalin overdose is commonly encountered. Treatment is supportive, and the use of extracorporeal treatments (ECTRs) is controversial. The EXTRIP workgroup conducted systematic reviews of the literature and summarized findings following published methods. Thirty-three articles (30 patient reports and 3 pharmacokinetic studies) met the inclusion criteria. High gabapentinoid extracorporeal clearance (>150mL/min) and short elimination half-life (<5 hours) were reported with hemodialysis. The workgroup assessed gabapentin and pregabalin as "dialyzable" for patients with decreased kidney function (quality of the evidence grade as A and B, respectively). Limited clinical data were available (24 patients with gabapentin toxicity and 7 with pregabalin toxicity received ECTR). Severe toxicity, mortality, and sequelae were rare in cases receiving ECTR and in historical controls receiving standard care alone. No clear clinical benefit from ECTR could be identified although major knowledge gaps were acknowledged, as well as costs and harms of ECTR. The EXTRIP workgroup suggests against performing ECTR in addition to standard care rather than standard care alone (weak recommendation, very low quality of evidence) for gabapentinoid poisoning in patients with normal kidney function. If decreased kidney function and coma requiring mechanical ventilation are present, the workgroup suggests performing ECTR in addition to standard care (weak recommendation, very low quality of evidence).

Acute coronary syndrome and transient global amnesia with sumatriptan.

Triptans are potent serotoninergic vasoconstrictors. They are generally avoided in elderly patients age greater than 65 or in patients with a history of CAD. Although there are reported cases of Acute Coronary Syndrome (ACS) or Transient Global Amnesia (TGA) in patients after ingesting therapeutic doses of triptan or dihydroergotamine, this is the first case report, up to our knowledge, of a patient, who had no previous cardiac history, that was diagnosed with both ACS and TGA. A 59-year-old woman with a long-standing history of migraine, gastroesophageal reflux disease, and hypothyroidism, presented to the Emergency Department (ED) complaining of amnesia, chest pain, and left arm numbness after ingesting a single dose of oral sumatriptan approximately 1-2 h prior to arrival. She had no recollection of the events that occurred after taking sumatriptan. No acute laboratory abnormalities were found except for an elevated troponin, which continued to trend upwards. Her EKG had no ST-T wave abnormalities. She was diagnosed with Acute Coronary Syndrome (ACS), non-ST elevation MI. She had a negative noncontrast CT head. Neurology was consulted for her amnesia and diagnosed her with Transient Global Amnesia (TGA). They recommended discontinuing sumatriptan and beginning topiramate as a prophylactic therapy. There is an increasing number of reports delineating sumatriptan's adverse effects. Emergency medicine physicians should promptly recognize the toxic effects and adverse reactions from triptans. Sumatriptan-induced vasoconstriction may lead to cardiac and cerebral ischemic events.

Synthetic Cannabinoid Exposure in Adolescents Presenting for Emergency Care.

OBJECTIVE: The objective of this study was to characterize the clinical picture and management of synthetic cannabinoid exposure in a cohort of adolescents. METHODS: Using the 45 participating sites of the Toxicology Investigators Consortium Registry, a North American database, we conducted an observational study of a prospectively collected cohort. We identified all adolescent (12-19 years) cases of synthetic cannabinoid exposure who have received medical toxicology consultation between January 2012 and December 2016. Clinical and demographic data were collected including age, sex, circumstances surrounding exposure, coingestants, clinical manifestations, treatment, disposition, and outcome. RESULTS: We identified 75 adolescents who presented to the emergency department with synthetic cannabinoid exposure. Most were male (91%) and between the ages of 16 and 19 (66%). The most common symptoms were neuropsychiatric with 50 adolescents (67%) exhibiting central nervous system (CNS) manifestations. There was no predominant toxidrome, and 9 patients (12%) were mechanically ventilated. Mainstay of treatment was supportive care. No deaths were reported. CONCLUSIONS: Synthetic cannabinoid exposure in adolescents is primarily characterized by CNS manifestations, which are varied and may be life-threatening. Frontline caregivers should maintain a high index of suspicion for synthetic cannabinoids, especially in adolescents who present with unexplained CNS manifestations, as there is no specific toxidrome or confirmatory rapid drug screen to detect them.

Cleaning and Disinfectant Chemical Exposures and Temporal Associations with COVID-19 - National Poison Data System, United States, January 1, 2020-March 31, 2020.

On January 19, 2020, the state of Washington reported the first U.S. laboratory-confirmed case of coronavirus disease 2019 (COVID-19) caused by infection with SARS-CoV-2 (1). As of April 19, a total of 720,630 COVID-19 cases and 37,202 associated deaths* had been reported to CDC from all 50 states, the District of Columbia, and four U.S. territories (2). CDC recommends, with precautions, the proper cleaning and disinfection of high-touch surfaces to help mitigate the transmission of SARS-CoV-2 (3). To assess whether there might be a possible association between COVID-19 cleaning recommendations from public health agencies and the media and the number of chemical exposures reported to the National Poison Data System (NPDS), CDC and the American Association of Poison Control Centers surveillance team compared the number of exposures reported for the period January-March 2020 with the number of reports during the same 3-month period in 2018 and 2019. Fifty-five poison centers in the United States provide free, 24-hour professional advice and medical management information regarding exposures to poisons, chemicals, drugs, and medications. Call data from poison centers are uploaded in near real-time to NPDS. During January-March 2020, poison centers received 45,550 exposure calls related to cleaners (28,158) and disinfectants (17,392), representing overall increases of 20.4% and 16.4% from January-March 2019 (37,822) and January-March 2018 (39,122), respectively. Although NPDS data do not provide information showing a definite link between exposures and COVID-19 cleaning efforts, there appears to be a clear temporal association with increased use of these products.

Shot by a Gun Missed by a Provider.

BACKGROUND: Botulism is a paralytic disease caused by the neurotoxin produced by Clostridium botulinum. The majority of cases are due to ingestion or injection drug use. Wound botulism from traumatic injury is exceedingly rare, with only one to two cases reported each year in the United States. CASE REPORT: A 27-year-old man presented to the Emergency Department with diplopia, dysphagia, and progressive weakness 10 days after sustaining a gunshot wound to his right lower leg. He had been evaluated for the same complaints at a different facility the day prior and was discharged. His wound appeared well-healing, but a high suspicion for wound botulism led to rapid consultation with the state Poison Control Center and the Centers for Disease Control and Prevention. The patient developed worsening respiratory insufficiency and required mechanical ventilation. Expeditious treatment with equine heptavalent botulinum antitoxin resulted in significant recovery of strength in 4 days. Serum toxin bioassay tested positive for botulinum neurotoxin type A. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Wound botulism now accounts for the majority of adult botulism in the United States. It should be considered in any patient with signs of neuromuscular disease and a recent injury, even if the wound appears uninfected.

Radial Head Subluxation: Factors Associated with Its Recurrence and Radiographic Evaluation in a Tertiary Pediatric Emergency Department.

BACKGROUND: Radial head subluxation (RHS) is a common complaint seen in the pediatric emergency department in children ages 6 months to 4 years. Classically, injury occurs due to axial traction on the arm, but this mechanism is not universal. Some patients will have recurrent RHS; some may undergo x-ray (XR) evaluation for alternative diagnosis. OBJECTIVES: To determine factors associated with recurrences and radiographic evaluations in RHS. METHODS: A retrospective study with inclusion criteria: under 10 years of age with discharge diagnosis "nursemaid," "radial head," or "subluxation." We examined factors associated with RHS recurrences, circumstances when radiographic evaluations performed, physician's training background (pediatric vs. general emergency medicine), mechanisms of injury, and demographic factors including age, gender, and arm involved. RESULTS: In 246 visits, median age was 27 months (interquartile range 16.1), with females comprising 55.7% (n = 137), and left-sided predominance (52%, n = 130). Mechanisms of injury were classified as "pull" (65.9%, n = 162), "non-pull" (15.9%, n = 39), and "unknown" (18.3%, n = 45). Eighteen patients with recurring RHS were more likely to be male (p = 0.008). In 61 visits where radiography was performed, patients were older (p = 0.03), with a higher frequency seen in non-pull and unknown mechanism (p = 0.0001). No significant difference was found in frequency of radiographs obtained in regard to physician training (p = 0.4660). CONCLUSION: RHS can result from a myriad of mechanisms. We found that recurrence was more likely in male patients. Factors associated with radiographic evaluation included atypical mechanism, older age, and unclear history, regardless of physician training background.

Extracorporeal Treatment for Metformin Poisoning: Systematic Review and Recommendations From the Extracorporeal Treatments in Poisoning Workgroup.

BACKGROUND: Metformin toxicity, a challenging clinical entity, is associated with a mortality of 30%. The role of extracorporeal treatments such as hemodialysis is poorly defined at present. Here, the Extracorporeal Treatments In Poisoning workgroup, comprising international experts representing diverse professions, presents its systematic review and clinical recommendations for extracorporeal treatment in metformin poisoning. METHODS: A systematic literature search was performed, data extracted, findings summarized, and structured voting statements developed. A two-round modified Delphi method was used to achieve consensus on voting statements and RAND/UCLA Appropriateness Method to quantify disagreement. Anonymized votes and opinions were compiled and discussed. A second vote determined the final recommendations. RESULTS: One hundred seventy-five articles were identified, including 63 deaths: one observational study, 160 case reports or series, 11 studies of descriptive cohorts, and three pharmacokinetic studies in end-stage renal disease, yielding a very low quality of evidence for all recommendations. The workgroup concluded that metformin is moderately dialyzable (level of evidence C) and made the following recommendations: extracorporeal treatment is recommended in severe metformin poisoning (1D). Indications for extracorporeal treatment include lactate concentration greater than 20 mmol/L (1D), pH less than or equal to 7.0 (1D), shock (1D), failure of standard supportive measures (1D), and decreased level of consciousness (2D). Extracorporeal treatment should be continued until the lactate concentration is less than 3 mmol/L (1D) and pH greater than 7.35 (1D), at which time close monitoring is warranted to determine the need for additional courses of extracorporeal treatment. Intermittent hemodialysis is preferred initially (1D), but continuous renal replacement therapies may be considered if hemodialysis is unavailable (2D). Repeat extracorporeal treatment sessions may use hemodialysis (1D) or continuous renal replacement therapy (1D). CONCLUSION: Metformin poisoning with lactic acidosis appears to be amenable to extracorporeal treatments. Despite clinical evidence comprised mostly of case reports and suboptimal toxicokinetic data, the workgroup recommended extracorporeal removal in the case of severe metformin poisoning.

Emergency Department Visits for Gastroenteritis Before and After Rotavirus Vaccine Implementation in 2006.

OBJECTIVES: Gastroenteritis (GE) accounts for a significant number of emergency department (ED) visits in children. Several studies since the introduction of a new rotavirus vaccine in 2006 have found decreases in rotavirus illness. We sought to determine in a large multicenter ED database whether there was also a decrease in ED visits in young children for GE. DESIGN: Retrospective cohort of ED visits. SETTING: 28 EDs with annual visits between 22,000 and 82,000. POPULATION: Consecutive patients between January 1, 1996, and December 31, 2011. PROTOCOL: We identified GE visits using International Classification of Diseases 9th revision (ICD-9) codes. For each year, less than 5 years, we determined the average daily percent of total ED visits for GE. We calculated the decreases from 2005 to 2011 in the average daily percent GE visits for each year of life and their 95% confidence intervals. RESULTS: There were 7,740,823 total visits in the database, and 811,317 (10.5%) are younger than 5 years. The annual percent of GE visits rose for all years of life from 1999 to 2005 and then decreased from 2005 to 2011. The decreases from 2005 to 2011 were greatest in the earliest years of life ranging from 41% in the first year of life to 15% in the fifth year of life. CONCLUSIONS: We found a decrease in average daily ED visits for GE in each year of life for those younger than 5 years after the introduction of the rotavirus vaccine. This was most pronounced during the earliest years of life.

Guidelines for reporting case studies on extracorporeal treatments in poisonings: methodology.

A literature review performed by the EXtracorporeal TReatments In Poisoning (EXTRIP) workgroup highlighted deficiencies in the existing literature, especially the reporting of case studies. Although general reporting guidelines exist for case studies, there are none in the specific field of extracorporeal treatments in toxicology. Our goal was to construct and propose a checklist that systematically outlines the minimum essential items to be reported in a case study of poisoned patients undergoing extracorporeal treatments. Through a modified two-round Delphi technique, panelists (mostly chosen from the EXTRIP workgroup) were asked to vote on the pertinence of a set of items to identify those considered minimally essential for reporting complete and accurate case reports. Furthermore, independent raters validated the clarity of each selected items between each round of voting. All case reports containing data on extracorporeal treatments in poisoning published in Medline in 2011 were reviewed during the external validation rounds. Twenty-one panelists (20 from the EXTRIP workgroup and an invited expert on pharmacology reporting guidelines) participated in the modified Delphi technique. This group included journal editors and experts in nephrology, clinical toxicology, critical care medicine, emergency medicine, and clinical pharmacology. Three independent raters participated in the validation rounds. Panelists voted on a total of 144 items in the first round and 137 items in the second round, with response rates of 96.3% and 98.3%, respectively. Twenty case reports were evaluated at each validation round and the independent raters' response rate was 99.6% and 98.8% per validation round. The final checklist consists of 114 items considered essential for case study reporting. This methodology of alternate voting and external validation rounds was useful in developing the first reporting guideline for case studies in the field of extracorporeal treatments in poisoning. We believe that this guideline will improve the completeness and transparency of published case reports and that the systematic aggregation of information from case reports may provide early signals of effectiveness and/or harm, thereby improving healthcare decision-making.

Prednisone for emergency department low back pain: a randomized controlled trial.

BACKGROUND: Although oral corticosteroids are commonly given to emergency department (ED) patients with musculoskeletal low back pain (LBP), there is little evidence of benefit. OBJECTIVE: To determine if a short course of oral corticosteroids benefits LBP ED patients. DESIGN: Randomized, double-blind, placebo-controlled trial. SETTING: Suburban New Jersey ED with 80,000 annual visits. PARTICIPANTS: 18-55-year-olds with moderately severe musculoskeletal LBP from a bending or twisting injury ≤ 2 days prior to presentation. Exclusion criteria were suspected nonmusculoskeletal etiology, direct trauma, motor deficits, and local occupational medicine program visits. PROTOCOL: At ED discharge, patients were randomized to either 50 mg prednisone daily for 5 days or identical-appearing placebo. Patients were contacted after 5 days to assess pain on a 0-3 scale (none, mild, moderate, severe) as well as functional status. RESULTS: The prednisone and placebo groups had similar demographics and initial and discharge ED pain scales. Of the 79 patients enrolled, 12 (15%) were lost to follow-up, leaving 32 and 35 patients in the prednisone and placebo arms, respectively. At follow-up, the two arms had similar pain on the 0-3 scale (absolute difference 0.2, 95% confidence interval [CI] -0.2, 0.6) and no statistically significant differences in resuming normal activities, returning to work, or days lost from work. More patients in the prednisone than in the placebo group sought additional medical treatment (40% vs. 18%, respectively, difference 22%, 95% CI 0, 43%). CONCLUSION: We detected no benefit from oral corticosteroids in our ED patients with musculoskeletal LBP.
