UNASSIGNED: Ethylene glycol poisoning causes metabolic acidosis, organ injury, and death. Ethylene glycol testing is unavailable in many areas. Our laboratory uses an automated glycerol dehydrogenase enzymatic assay to screen for ethylene glycol. We sought to determine how often ethylene glycol results were available within 12 h of the first dose of fomepizole.
UNASSIGNED: Records from a single poison center were reviewed from December 2016 to December 2019. Cases were identified by searching for cases that received fomepizole. Outcomes included whether results were available within 12 h, and the turnaround time from time of laboratory order to result.
UNASSIGNED: Of the 125 cases of suspected toxic alcohol poisoning identified, 73 had screening for ethylene glycol by enzymatic assay. Results were available within 12 h of the initial fomepizole dose in 58 (79%) cases with a median turnaround time of 391 min.
UNASSIGNED: We have demonstrated clinically acceptable turnaround times using an automated screening ethylene glycol assay. The major limitations include lack of approval for this test at this time, the use of voluntarily reported poison center data, and lack of assessment of patient outcomes.
UNASSIGNED: Enzymatic screening for ethylene glycol yielded results within 12 h in 79% of cases.

Loxosceles is an arachnid genus comprising several species in the United States, popularly known as brown recluse spiders. The venom is cytotoxic, complex, and has a mixture of many proteins, some of which function as proteases. Envenomation can cause necrotic skin lesions that may become extensive and take many months to heal. Even more rarely, venom may cause systemic effects, leading to widespread hemolysis, coagulopathy, and death. These symptoms typically occur rapidly within 24-48 hours following the bite. We describe a rare case of a 44-year-old male with fatal systemic loxoscelism with orbital compartment syndrome requiring emergent lateral canthotomy and cantholysis.

Mushroom poisonings are common in the United States. Gyromitrin (acetaldehyde N-methyl-N-formylhydrazone) is a clinically significant mycotoxin primarily associated with the lorchel (i.e. the false morel) Gyromitra esculenta. Resemblance between \'true and false morels\' has resulted in misidentification of Gyromitra spp. as edible and sought after Morchella spp., resulting in toxicity. Despite literature evidence outlining toxic sequalae, Gyromitra spp. mushrooms are commonly consumed and prepared for culinary purposes. Classic clinical teachings emphasize significant neurotoxicity, including seizures, associated with ingestion of gyromitrin-containing mushrooms, stemming from gyromitrin\'s terminal metabolite monomethylhydrazine. We performed a longitudinal descriptive review of the clinical toxicity associated with ingestion of mushroom species known or suspected to contain gyromitrin in cases reported to the Michigan Poison & Drug Information Center between January 1, 2002, to December 31, 2020. Our 19-year descriptive case series of gyromitrin-containing mushroom ingestions reported to our Center demonstrated a preponderance of gastrointestinal signs and symptoms, including hepatotoxicity. Of 118 identified cases, 108 (91.5%) of the reported ingestions involved Gyromitra esculenta. The most frequent clinical findings associated with symptomatic ingestions (n = 83) were the aforementioned gastrointestinal symptoms (n = 62; 74.7%). Neurological symptoms were less frequent (n = 22, 26.5%) while hepatotoxicity occurred in fewer patients (n = 14; 16.9%). Of symptomatic patients, most were treated with symptomatic and supportive care (n = 58; 70%). Pyridoxine was used in a total of seven patients (n = 7; 8.4%) with either hepatotoxicity or neurotoxicity. Medical outcomes ranged from minor to major, with no reported deaths. Patient presentations (i.e. GI vs. neurotoxic symptoms) following ingestion of gyromitrin-containing mushrooms may be highly variable and multifactorial, owing to differences in dose ingested, geographical distribution, genetic variability of both patient and mushroom species, and species-specific differences in toxin composition. Future research warrants species-level identification of ingested gyromitrin-containing mushrooms and investigating the contribution of genetic polymorphisms to differences in clinical toxidromes.

UNASSIGNED: To independently validate the negative predictive value of the Tanta University risk model for intensive care requirements in poison center telephone consultations with other physicians.
UNASSIGNED: This study included 400 consecutive patients with acute poisoning. Clinical and laboratory parameters were recorded during the initial consultation with the poison center. Patients who were already ventilated or on vasopressors at the time of consultation were excluded. The Tanta University risk model score was calculated from the data according to the following equation: Tanta University risk model score = 1.966*Glasgow Coma Scale + 0.329*oxygen saturation (percent) + 0.212*diastolic blood pressure (mmHg) - 0.27*respiratory rate (breaths/minute) + 0.33*standard bicarbonate (mmol/L). Twenty-four hours later, the patients\' courses were followed up by telephone. The Tanta University risk model was then compared to a composite endpoint indicating the requirement for admission to an intensive care unit (vasopressors, need for intubation, or death).
UNASSIGNED: Four hundred patients with acute poisoning were included. Thirty-seven patients had a complicated clinical course as defined by the composite endpoint. Receiver operating characteristic analysis revealed the area under the curve to be 0.87 (95 percent confidence interval 0.83-0.90). An unfavorable Tanta University risk model score was defined as less than 73.46, using a cut-off derived from a previous study of an unrelated series of patients with acute poisoning admitted to our service. Thirty-one of 37 patients with complicated courses had an unfavorable Tanta University risk model score compared to six patients with complicated courses among 306 patients with a favorable Tanta University risk model score (P < 0.0002, Fisher\'s exact test). Sixty-three patients had an unfavorable Tanta University risk model score but an uneventful course. The negative predictive value of the Tanta University risk model was 0.98 (95 percent confidence interval 0.96-0.99), sensitivity was 0.84, and specificity 0.83.
UNASSIGNED: In the present study of poison center telephone consultations, the Tanta University risk model was significantly related to the outcomes in patients with acute poisoning. Patients with a favorable Tanta University risk model score (greater than or equal to 73.46) were unlikely to need intensive care unit level of care.

UNASSIGNED: Acute accidental poisoning in children remains a significant public health issue and a predictable cause of morbidity around the world. To take preventive measures, it is necessary to identify the pattern of this problem.
UNASSIGNED: To determine the extent and characteristics of paediatric poisoning, an epidemiological investigation specific to each country is required. The goal of our research was to determine the current pattern of acute poisoning in children between (0-5) years old in Jordan.
UNASSIGNED: This retrospective study performs a descriptive analysis of the Jordan University Hospital\'s National Poison Information Center (NPIC) database and describes the epidemiology of acute poisoning in children between (0-5) years old during a period of two years (2018-2019).
UNASSIGNED: Paediatric poisoning (0-5) years old accounts for approximately 88% of poisoning cases in Jordan between 2018 and 2019.Out of 3531 paediatric poisoning cases, 44.9% of cases were in children between (2-3) years old, 63.4% of subjects were male. 40.9% of calls were from governmental hospitals. Most cases occurred at home (98.7%) and were unintentional (98.6%). Medication poisoning was the commonest among cases (71.0%). Besides, 89.4% were asymptomatic at the time of call, and Central Nervous System (CNS) symptoms being the most common (3.6%) among the symptomatic cases.
UNASSIGNED: Most cases of paediatric poisoning handled by the NPIC was due to medications. To prevent or minimize these cases, it is necessary to educate parents and other caregivers about proper medication storage and use, and in case of poisoning, urgent referral to health facilities is required.

In July 2020, an outbreak of methanol-contaminated hand sanitizers in the United States prompted our regional poison center to implement a more conservative triage guideline for hand sanitizer exposures. All pediatric hand sanitizer ingestions of more than a \"taste\" were referred to a healthcare facility for assessment. We then evaluated the effect of this change on identifying patients with methanol poisoning.
This was a single-center, retrospective review of pediatric (<19 years) hand sanitizer ingestions reported to our poison center from May 1, 2020 through January 28, 2022. Methanol and ethanol concentrations were collected if available.
During the study period, we received 801 calls regarding hand sanitizer exposure, of which 140 children were referred to a healthcare facility for hand sanitizer ingestions. Of those, 88 (63%) had methanol and/or ethanol concentrations measured. No child had a detectable methanol concentration, 78 had ethanol testing, and 12 had a detectable ethanol concentration.
In this sample, no patient tested had a detectable methanol concentration. Children who consumed enough to have a detectable ethanol concentration were symptomatic or had an intentional ingestion. Asymptomatic children with unintentional ingestion of hand sanitizer were at low risk for methanol toxicity.

Although poisonings due to a toxic substance being decanted into a secondary container are often reported to poison centers, we were unable to locate prior European data about their circumstances, incidence and consequences. We sought to describe the circumstances and outcomes of this behavior.
We conducted a prospective study of all poison exposures involving transfer to a secondary container reported to our poison center during a six month interval (January 1, 2021 through June 30, 2021). We called patients and clinicians for follow up the next day. We used a prepared questionnaire and added the responses to the national database for French poison centers.
We identified and included 238 patients (104 male, 134 female) with a median age of 39 years [range 0-94 y]. Exposure was mainly oral (n = 221), the secondary container was mainly a water bottle (n = 173), toxic substances were essentially cleaning products (n = 63) or bleach (n = 48). Symptoms were gastrointestinal (vomiting, diarrhea, abdominal pain) (n = 143) or respiratory (cough, dyspnea, aspiration pneumonia) (n = 15). The World Health Organisation/International Programme on Chemical Safety/European Commission/European Association of Poison Centres and Clinical Toxicologists Poisoning Severity Score was none in 76 cases (31.9%), minor in 147 (61.8%), moderate in 12 (5%), and severe in three cases (1.3%). Products that led to severe poisoning contained either ammonium hydroxide or sodium hydroxide. Two of the patients required intensive care treatment. At the end of the follow-up, 235 patients fully recovered, and three patients had sequelae.
The study illustrates the risk of toxic substance transfer. Water bottles were the secondary containers in most exposures to decanted substances. Most had minor or no effects, but nearly one-quarter were admitted to the hospital. The few severe exposures involved either ammonium hydroxide or sodium hydroxide.

Acute poisoning is a significant international public health issue and one of the leading causes of death in the emergency department (ED). In the absence of any previous reports describing the poisoning profile in Syria, we present this study to assess the epidemiological and clinical characteristics of poisoning over 21 years.
We collected the data retrospectively from the Syrian Poisons Information Centre (SPIC) from January 1999 until December 2020. The data included patients who had accidental or non-accidental exposure to poisons, either by drugs, medicaments, and biological substances or substances chiefly nonmedicinal sources such as soaps and detergents, corrosive substances, pesticides, and other miscellaneous products.
We collected the data of 120,972 poisoned patients, of whom 52.6% were females, and 47.4% were males. Aleppo governorate reported the highest number of poisoned cases (28.6%), followed by Damascus governorate (19.9%). The highest poisoning rates were recorded in 2020, 2014, and 2010. Pharmaceutical (37.0%) and animal (33.8%) sources were the most common causative agents. The oral route was the route of poisoning in 58.3% of patients, and 33.4% through the skin. The most common poison was scorpion stings 19.5% while the most common cause of death was organophosphates 15.7%.
The differences in socioeconomic status, cultural habits, and agricultural and industrial activities between countries have led to a state of fluctuation regarding the most common poisoning agents.
Damascus and Aleppo, the two major governorates in Syria, had the highest poisoning cases. Oral administration of pharmaceutical agents was responsible for most of the poisoning cases. The most common individual poison was the scorpion poison, while the top killer was organophosphates.

The objective of this study was to evaluate trends and characteristics in adolescent poison center (PC) exposure calls before and during the COVID-19 pandemic.
A retrospective review of PC calls for adolescents aged 13-17 years from January 1, 2018 through June 30, 2021.
During the pandemic, US PCs had a higher proportion of adolescent exposure calls managed in a healthcare facility (71.9% vs. 67.4%) and hospital admissions (27.2% vs. 25.7%) than prior to the pandemic. There was a higher proportion with suicide intent (55.8% vs. 48.8%), moderate/major clinical effects (22.8% vs. 20.1%), and deaths (0.07% vs. 0.05%). Monthly calls significantly increased from 30 calls/month to 204 calls/month (p < .001). The slope of hospital admissions significantly increased (0.19% per month, p < .001) during the pandemic.
During the COVID-19 pandemic, US PCs observed an increase in adolescent suicidal intent exposure calls with more severe outcomes, hospitalizations, and deaths.
