Background: Despite its preventable nature, poisoning remains one of the leading causes of morbidity and mortality in the pediatric population. In Lebanon, this population is poorly studied and there is no poison center to which healthcare providers and the public can refer in case of toxicological exposure, leading to unnecessary Emergency Department (ED) visits. This study describes the pediatric toxicological exposures seen at the largest tertiary care center in Lebanon. It also evaluates the appropriateness of ED visits among confirmed or suspected toxicological exposures in children, in order to assess the role of a national poison center in reducing unnecessary ED visits. Methods: This is a secondary analysis of a database for a telephonic medical toxicology service at the American University of Beirut Medical Center, the largest tertiary care center in Lebanon. Data relating to all pediatric patients aged 0-19 years of age were entered into the database by the medical toxicology team. The cases were independently reviewed by 2 medical toxicologists for the adequacy of referral to the ED and performance of invasive procedures. Results: Two hundred and nine exposures were recorded between 15 April 2015 and 31 December 2019, of which 53.1% were females. Children aged less than 5 years were involved in 67.0% of cases while adolescents aged 13-19 years were involved in 21.1%. The most commonly involved substances were analgesics (14.8%) and cardiovascular drugs (10.0%). The majority had no (59.3%) or minor (26.3%) effects and were treated and discharged home (67.5%). More than a third of ED visits were deemed unnecessary by the toxicologists (Kappa ¼ 0.705), and when including only unintentional cases, around 45% of the ED visits were deemed unnecessary (Kappa ¼ 0.677). Conclusion: Our data show that 37% of all pediatric poisoning ED visits and 45% of ED visits due to unintentional pediatric poisonings were unnecessary. Additionally, more often than not lavage suctions were done unnecessarily. Future research investigating the possibility of preventing unnecessary visits by establishing a national poison center is needed.

Household products intoxication is a common and preventable problem. Household product hazard awareness is lacking among consumers in Lebanon, posing a public health hazard. A cross-sectional observational study was conducted at the American University of Beirut Medical Center by administering surveys to 176 adult participants. The surveys focused on demographics, awareness of product toxicity, practices used to avoid intoxication, and sources of information. Each participant was given a score for behavior and awareness. Informative brochures were handed to increase awareness among consumers. We surveyed 176 patients, of whom (84.7%) were females with a mean age of 42.2 ± 13.5 years. Most were married (77.3%), had a college education (76.7%), were employed (62.5%), and were in charge of household cleaning (76.7%). Toilet cleaners were the substances most perceived to be toxic (94.0%). Most people (86.4%) had low to medium scores on behavior, while most (77.3%) had high scores on awareness. Male gender and using product labels as sources of information were associated with higher behavior scores, while referring to a friend or a relative as a source of information on product intoxication was associated with a lower behavior score. Greater awareness scores were strongly associated with being married, having a higher monthly income, and referring to warning signs presented on the labels as a source of knowledge. Unsafe handling and storage of household products are common among consumers in our population. Therefore, it may be necessary to launch education campaigns to improve consumer handling of household products.

Neuro-ophthalmological emergencies require prompt assessment and management to avoid vision or life-threatening sequelae. The decision to perform a neuroimaging procedure is based on the clinical judgment of the medical team, without defined indications. This study aims to identify presenting symptoms and physical exam findings associated with relative positive findings on neuroimaging studies. Electronic medical records of patients presenting to the emergency department (ED) with isolated neuro-ophthalmologic complaints between January 1, 2013 and September 30, 2019 were reviewed. We collected data on the clinical presentation, neuroimaging procedures and results, consults, and diagnoses. Two hundred eleven patients’ charts were reviewed. Most presented with unilateral eye complaints (53.6%), and the most common symptoms were blurred vision (77.3%) and headaches (42.2%). A total of 126 imaging procedures were performed of which 74.6% were normal, while 25.4% showed relevant abnormal findings. Complaining of blurry vision (P = .038) or visual field changes (P = .014) at presentation as well as having a visual field defect (P = .016), abnormal pupil reactivity (P = .028), afferent pupillary defect (P = .018), or abnormal optic disc exam (P = .009) were associated with positive findings on imaging. Neuroimaging is more likely to yield positive findings in patients presenting to the ED with visual field irregularities, afferent pupillary defects, or abnormal optic discs. These findings – when combined with the proper clinical setting – should lower the threshold to proceed with neuroimaging in the emergency department. Based on our results, larger-scale studies might lead to a well-structured algorithm to be followed by ED physicians in decision making.
