BACKGROUND: Acute carbon monoxide (CO) poisoning is one of the most common poisons worldwide and neuropsychiatric sequelae (NS) are the most frequent form of its morbidity. OBJECTIVES: This study aimed to measure the percentage of patients liable to NS, to evaluate the cognitive profile of patients with NS and to assess the role of neuron specific enolase (NSE) and glial fibrillary acidic protein (GFAP) in predicting the development of NS after acute CO poisoning. METHODS: This prospective study included 50 patients with acute CO poisoning presented to the Poison Control Center, Ain Shams University Hospitals during the period from beginning of November 2015 till the end of January 2017. Patients' demographic characteristics, clinical manifestations and blood carboxyhemoglobin levels were recorded. Serum levels of NSE and GFAP were determined on admission. Every patient was invited to participate in a follow-up visit at a dedicated outpatient clinic one month after CO exposure. During the visit, a complete neurological examination, as well as a psychiatric evaluation using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders version 4 Axis-I were performed for detection of neurological and psychiatric disorders. Wechsler memory scale test was administrated for detection of cognitive deficits. The patients were divided into two groups based on the presence or absence of NS. RESULTS: Cognitive impairment was found in 38 % of patients in the NS group. The serum levels of NSE and GFAP were significantly high in the NS group in comparison to the non-NS group. Receiver operating characteristic curves (ROC) determined the cut-off level of NSE at 39 ng/mL achieved 100 % sensitivity with 88.64 % specificity to predict the development of NS after acute CO poisoning while GFAP had 95.24 % sensitivity and 69.23 % specificity at a cut-off value of 2.8 ng/mL. CONCLUSION: NSE and GFAP could be useful in the early identification of patients at risk of developing NS after CO poisoning helping in treatment plans and thus improving quality of care.

Benzodiazepines, often used to treat anxiety, insomnia, and other conditions, are prescribed more frequently to women than men, and emergency department visits and overdose deaths involving benzodiazepines have increased significantly among women in recent years. This study describes characteristics and trends associated with benzodiazepine exposures among women of reproductive age (15-49 years old) that were reported to United States poison control centers from 2004 through 2018. The National Poison Data System recorded 258,370 first-ranked benzodiazepine exposures among women 15-49 years old during the study period. More than one-half (56.9%) of exposures involved a single-substance and one-third (34.0%) occurred among women 20-29 years old. The majority were categorized as "intentional, suspected suicide" (73.2%) or "intentional" (12.9%). Exposures frequently resulted in admission to a psychiatric facility (20.6%), critical care unit (18.1%), or non-critical care unit (9.3%). Twenty percent of cases resulted in a serious medical outcome, including 205 deaths. The substantial percentage of benzodiazepine exposures among women of reproductive age that were intentional and associated with suicide attempts or suicide deaths indicate that increased prevention efforts are needed to address this issue.

CONTEXT/OBJECTIVES: A significant proportion of individuals aged 50+ in the U.S. use cannabis for medical or recreational purposes, sometimes with adverse effects. Given differences in cannabis use among men and women, we examined sex differences in (1) cannabis forms used, (2) exposure reasons, and (3) medical outcomes in older-adult poison control center (PCC) cases. METHODS: Data came from the American Association of Poison Control Centers' National Poison Data System, 2009-2019. We focused on the 3633 cases aged 50+ in which plant and other non-synthetic cannabinoid cannabis forms were the only or primary substance. Logistic regression was used to examine associations of sex with cannabis forms. Multinomial logistic regression models were fit to examine associations of sex with exposure reasons (therapeutic errors/adverse reactions, intentional misuse/abuse, other) and medical outcomes (no-to-minimal, moderate, or major effects). RESULTS: Females constituted 57.4% of cases. In multivariable analyses, female cases had 1.20 (95% CI = 1.01-1.43) greater odds of involving cannabis forms other than plant forms and 1.93 greater odds (95% CI = 1.66-2.24) of therapeutic errors/adverse effects compared to intentional misuse/abuse. Older age and occurrence in recreational-cannabis-legal states were positively associated with other cannabis forms. Older age, recreational and/or medical cannabis-legal states, CBD, pharmaceuticals, concentrated extracts, and chronic exposure were associated with higher odds of therapeutic errors/adverse effects. Sex was not significantly associated with medical outcomes. CONCLUSIONS: Female cases compose a large share of PCC cases aged 50+ and are associated with higher odds of involving cannabis forms other than plants and therapeutic errors/adverse reactions compared to intentional misuse/abuse.

Data System. The American Association of Poison Control Centers (AAPCC) and the Centers for Disease Control and Prevention (CDC) jointly monitor the National Poison Data System (NPDS) for incidents of public health significance (IPHSs).Data Collection/Processing. NPDS is the data repository for US poison centers, which together cover all 50 states, the District of Columbia, and multiple territories. Information from calls to poison centers is uploaded to NPDS in near real time and continuously monitored for specific exposures and anomalies relative to historic data.Data Analysis/Dissemination. AAPCC and CDC toxicologists analyze NPDS-generated anomalies for evidence of public health significance. Presumptive results are confirmed with the receiving poison center to correctly identify IPHSs. Once verified, CDC notifies the state public health department.Implications. During 2013 to 2018, 3.7% of all NPDS-generated anomalies represented IPHSs. NPDS surveillance findings may be the first alert to state epidemiologists of IPHSs. Data are used locally and nationally to enhance situational awareness during a suspected or known public health threat. NPDS improves CDC's national surveillance capacity by identifying early markers of IPHSs.

Objectives. To evaluate the effect of the voluntary safety standard for liquid laundry packets on the rate of injury involving children younger than 5 years in the United States.Methods. Semiannual national estimates of child injuries involving liquid laundry packets treated in US hospital emergency departments were developed for the July 2012 through December 2018 study period. We used a negative binomial regression model to estimate the effect of the voluntary standard on the injury rate following the standard's publication at the end of 2015. The analysis controlled for the rapid growth of laundry packet use during the study period. Results are presented as relative risks and percentage changes in the injury rate.Results. The voluntary standard was associated with a 49.4% to 61.6% reduction in the rate of child injury.Conclusions. The results suggest that the requirements of the voluntary standard have effectively reduced the rate of child injury involving liquid laundry packets and may have prevented 9200 to 23 000 emergency department-treated injuries during the study period.

BACKGROUND: Our objective was to describe trends and deaths in young children associated with opioid analgesics. METHODS: Analysis of pediatric exposures using the RADARS System Poison Center Program from July 1, 2010 through December 31, 2018. Cases involving a child < 6 years, with an exposure to one or more opioids: buprenorphine, fentanyl, hydrocodone, hydromorphone, methadone, morphine, oxycodone, oxymorphone, and tramadol. Poisson regression was used to model the shape of the time response curve. RESULTS: 48,560 cases were identified, median age 2 years (IQR 1.4, 2.0), 52.4 % male. The most commonly involved opioid was hydrocodone (32.5 %); buprenorphine and methadone had the highest exposure rates when adjusted for dispensed prescriptions (0.84 and 0.73 per 10,000 prescriptions). There were 28 deaths, methadone being the most commonly involved opioid (16). Exposures decreased significantly accounting for population (from 8.39 to 4.19 exposures per 100,000 children) and per prescription (from 0.33 to 0.25 exposures per 10,000 prescriptions). After adjustment for prescriptions, the exposure rate for hydromorphone and fentanyl increased over the study period, while buprenorphine had the greatest decrease in exposure rate. Among 28 deaths, 11 (39 %) were known or suspected to have been exposed, but medical care was not sought or was delayed. CONCLUSION: Pediatric opioid exposure rates by prescription and population decreased from July 2010 through December 2018. However, with over 48,000 exposures and 28 deaths, the opioid epidemic continues to impact young children. Many exposures including deaths were preventable. Continued improvements in prevention require a multifaceted approach.

France is experiencing an increase in the number of opioid prescriptions and related fatalities. We carried out a retrospective observational study using data from the Paris PCC over a 10-year period. The main objective was to obtain an epidemiological description of the severe reported cases. The secondary objectives were to assess the evolution of the number of these cases and their severity defined by the use of fentanyl and its derivatives, the use of the opioid-poisoning treatment naloxone, and the number of fatalities. During 2008-2017, 268 511 cases were recorded, including 1 122 cases of opioid-related poisoning that required medical management. These poisonings involved tramadol (43%), codeine (25%), dextropropoxyphene (13%), and morphine (8%); most resulted from self-exposure (60%). During the 10-year study period, 130 opioid-related fatalities were recorded in the Paris area, mainly resulting from suicides (39%) in men and were attributed to morphine (27%), tramadol (24%), and methadone (21%). We did not identify an increase in the number of severe opioid-related poisonings or fatalities or in the use of fentanyl or its derivatives. Conversely, we observed an increase in the use of naloxone, suggesting an increase in the severity of opioid poisonings. Our findings show that, until 2017, the opioid overdose epidemiology in the Paris area is different to that in the USA. The systematic analysis of data from the PCCs could be a good tool for health monitoring. To assess trends in France, a national study over a longer period would also be useful.

OBJECTIVES: States in the US are controlling opioid prescribing to combat the opioid epidemic. Prescription Drug Monitoring Programs (PDMPs) were widely adopted, whereas less attention was given to pain clinic laws. This study examined the associations of mandatory use of PDMPs and pain clinic laws with prescription opioid exposures. METHODS: State-level quarterly prescription opioid exposures reported to the National Poison Data System during 2010-2017 were analyzed. The primary outcome was age-adjusted rates of prescription opioid exposures per 1,000,000 population. The primary policy variables included the implementation of mandatory use of PDMPs alone, the implementation of pain clinic laws alone, and the implementation of both mandatory use of PDMPs and pain clinic laws. Linear regressions were used to examine the associations, controlling for other opioid policies, marijuana policies, socioeconomic factors, state fixed effects, time fixed effects, and state-specific time trends. RESULTS: Requiring mandatory use of PDMPs alone was not associated with significant changes in prescription opioid exposures. The implementation of pain clinic laws with or without concurrent mandatory use of PDMPs was associated with 5 fewer prescription opioid exposures per 1,000,000 population or a 9 % reduction compared to the pre-policy period (pâ¯<â¯0.01). Further analysis revealed that the reduction associated with pain clinic laws was pronounced in exposures reported by healthcare facilities. CONCLUSIONS: This multi-state study provided new evidence that the implementation of pain clinic laws was associated with a significant reduction in prescription opioid exposures. Pain clinic laws may deserve further evaluation and consideration.

OBJECTIVE: This study aims to evaluate the trends and risk factors of severe buprenorphine outcomes (SBO) reported to the U.S. Poison Centers (PCs). METHODS: We queried the National Poison Data System for exposures to buprenorphine from 2011 to 2016. SBO cases were defined as exposures that resulted in either a death or major clinical outcomes. Trends were tested using Poisson regression. Characteristics of the exposures were descriptively assessed. Logistic regression was used to evaluate the risk factors of SBO. RESULTS: SBO cases (967) reported to the PCs increased by 66.6% during this period (114-190, pâ¯<â¯0.001). While adults between 20 and 39 years were more frequent in the SBO group (50.4%) compared to the non-SBO group (38.7%), cases under 6 years (29.6% vs 13.8%) were more common among the non-SBO group. Intentional abuse (20.1% vs 24.9%) and suspected suicides (13.7% vs 37.5%) were significantly higher among the SBO group. Multisubstance exposures were more frequent among the SBO cases (36.4% vs 71.4%). SBO risk increased with age, with cases above 60 years (AOR: 1.66, 95% CI: 1.14-2.42) demonstrating significantly increased odds. Suspected suicide (AOR: 1.87, 95% CI: 1.53-2.28) and abuse (AOR: 1.40, 95% CI: 1.13-1.73) cases were more likely to result in a SBO. Multisubstance exposures significantly increased the risk of a SBO. CONCLUSIONS: This study reflected an increase in the cases of SBO paralleling the rise in the buprenorphine prescriptions. Age, reasons for exposure and multi-substance exposures significantly increased the risk of SBO.

BACKGROUND: Lacosamide (Vimpat®) is an anticonvulsant used to treat partial-onset seizures. Little is known about the characteristics and outcomes of patients exposed to lacosamide. OBJECTIVE: To characterize lacosamide exposures reported to US poison centers with regard to patient demographics, clinical effects, and outcomes. METHODS: This retrospective observational study queried the National Poison Data System (NPDS) for single substance lacosamide exposures from January 2008 to December 2016. Variables of interest included age, gender, medical outcome, management site, level of healthcare facility, reason for exposure, and clinical effects. RESULTS: Lacosamide exposures were identified in 1124 patients, ranging from ages 2 months to 99 years. Six hundred and twenty-two patients (55.3%) were female. Nine hundred and seventy-six patients (86.8%) had minimal or no toxic effects. Life-threatening exposures numbered 30 cases (2.7%). There was one death. Five hundred and forty-eight patients (48.8%) did not require healthcare management while 537 (47.7%) were either referred to or already at a hospital. Among those treated at a healthcare facility, 269 (50.1%) did not require admission. Thirty-three patients (6.1%) were admitted to a psychiatric facility, 68 (12.7%) to a non-critical care unit, and 93 (17.3%) to a critical care unit. Six hundred and thirty-two exposures (56.2%) were due to therapeutic error. Suicide attempts numbered 168 (14.9%). Neurologic, gastrointestinal, and cardiovascular symptoms were commonly encountered. CONCLUSION: Lacosamide exposures infrequently cause death or disability; however, a considerable proportion of the study population required intensive care. Exposed patients with symptoms require healthcare evaluation.

OBJECTIVES: Adolescent depression and attempted and completed suicide are increasing in the United States. Because suicide is often impulsive, the means of self-harm are frequently items of convenience like medication. Authors of a recent study compared tricyclic antidepressant overdose to bupropion overdose. Fluoxetine and escitalopram are the only agents with Food and Drug Administration approval for pediatric depression, but off-label bupropion prescriptions are common. We sought to compare the effects of selective serotonin reuptake inhibitors (SSRIs) and bupropion in overdose. METHODS: This was an analysis of the National Poison Data System from June 2013 through December 2017 for adolescent (ages 10-19) exposures to SSRIs or bupropion coded as "suspected suicide." Demographics, clinical effects, therapies, and medical outcome were analyzed. RESULTS: There were 30 026 cases during the study period. Sertraline and fluoxetine accounted for nearly 60%, whereas bupropion was reported in 11.7%. Bupropion exposure was significantly associated with death (0.23% vs 0%; P < .001) or serious outcome (58.1% vs 19%; P < .001) as well as the 10 most common clinical effects, including seizures (27.0% vs 8.5%; P < .001) and hallucinations (28.6% vs 4.3%; P < .001). Bupropion exposure was significantly associated with the need for cardiopulmonary resuscitation (0.51% vs 0.01%; P < .001), intubation (4.9% vs 0.3%; P < .001), vasopressors (1.1% vs 0.2%; P < .001), and benzodiazepines (34.2% vs 5.5%; P < .001). There was a significant increase in all exposures and in proportion of serious outcomes over time. CONCLUSIONS: Adolescents who attempt self-harm are at higher risk for serious morbidity and poor outcomes with bupropion than with SSRIs. These risks, and the patient's propensity for self-harm, should be evaluated when therapy with bupropion is considered.

In 2008, 30 active substances from plant protection products were banned from marketing in France. Nevertheless, the French Poison Control Centers continue to see cases of poisoning caused by these active substances that are no longer approved. The aim of this study was to describe the characteristics of the reported cases in mainland France and in overseas French territories, over the period 2012-2016. A total of 408 cases of human exposure were reported during the study period. The most commonly reported substances were dichlorvos (24.8%, n = 108), paraquat (23.8%, n = 97), aldicarb (14.7%, n = 60), diuron (9.6%, n = 39), dinocap (5.1%, n = 21), methomyl (4.2%, n = 17), carbofuran (3.9%, n = 16), anthraquinone (2.9%, n = 12) and carbendazim (2.7%, n = 11). The number of cases of intoxication dropped sharply between 2012 (n = 119) and 2016 (n = 47), except in the overseas French territories. Among the 72 serious cases (severe or life-threatening or with a fatal outcome), the most common substances involved were paraquat (n = 34), aldicarb (n = 24) and carbofuran (n = 7). This study suggests persistent use of carbamate insecticides, the existence of illegal imports of dichlorvos or paraquat-based products, and the use of certain banned fungicides in the professional agricultural sector. Information and collection campaigns are therefore essential after the withdrawal of marketing authorization for the plant protection products.

OBJECTIVE: Adolescent intentional ingestions remain a significant public health problem in the United States with little research to date on the over-the-counter or prescription medicines that adolescents abuse. These data are important for anticipatory guidance by primary care providers, preventive health, and poison center outreach. METHODS: This was an observational study using the American Association of Poison Control Centers National Poison Data System. The study population consisted of all cases of patients aged 13 to 19 years from 2004 to 2013 with a coding of "intentional abuse." RESULTS: There were 95,695 patient calls that were coded for intentional abuse between 2004 and 2013 for adolescents aged 13 to 19 years. The most common agent reportedly ingested in intentional-abuse cases was antihistamine and/or decongestant with dextromethorphan, and this agent remained the most common throughout the 10-year study period. The next 4 most common agents remained similar across the study period as well and included ethanol, benzodiazepines, dextromethorphan alone, and marijuana. These 5 agents remained the most commonly reported across the study period for all US regions (West, Midwest, South Northeast, and US territories). CONCLUSIONS: Over a recent 10-year period, common cough preparations remain the most commonly reported intentional abuse ingestion among all years and regions for adolescents.

AIM: to describe trends in baclofen reports to Australia's largest Poisons Information Centre (PIC) and present a case series detailing severity of overdoses. SHORT SUMMARY: PBS data demonstrates baclofen use is increasing in Australia, while calls to NSWPIC illustrate an increase in number of exposures associated with toxicity. Baclofen toxicity may require prolonged intensive care admission. To minimize harms associated, especially with off-label baclofen prescribing for AUD, prescribers should pay careful attention to psychiatric comorbidities, and closely monitor treatment and dispensing. METHODS: this is a retrospective observational study of baclofen overdoses reported to New South Wales PIC (NSWPIC) from January 1 2004 to 31 December 2016. In addition, referrals to a metropolitan toxicology service relating to baclofen toxicity from 2014 to 2017 were analysed. The number of Pharmaceutical Benefit Scheme (PBS) claims for baclofen were also reviewed. RESULTS: during the 13-year study period, 403 cases of baclofen toxicity were reported to NSWPIC. There was a 230% increase in annual exposures over this period, 71% of patients were symptomatic, with 77% requiring hospitalization. Coingestants were reported in 53%, with 57% being psychoactive medications (including alcohol). An increase in number of baclofen dispensing episodes was also noted. From the five cases of deliberate self-harm reported to the metropolitan toxicology service, three obtained baclofen for management of alcohol use disorder (AUD) and required prolonged treatment in the intensive care unit (ICU). CONCLUSIONS: NSWPIC data shows an increase in number of calls regarding intentional baclofen exposures in parallel with increase the number of baclofen PBS claims. These closely parallel the increase in dispensing of baclofen since 2008. Case studies presented reinforce the severity of baclofen toxicity. Together, they demonstrate the potential risk of harm of baclofen prescribing, and the greater need for caution. Baclofen should be considered carefully in patients high risk of overdose or be used only in specialist services with close monitoring.

BACKGROUND: This study sought to examine ketamine exposures reported to US poison centers over the past 16â¯years and identify trends in exposures and outcomes. METHODS: A retrospective review was performed of all cases involving ketamine exposures reported to US poison centers and entered into the National Poison Data System from 2000 to 2015. Cases were divided into those involving ketamine alone and those involving ketamine and other agents. Data collected included: age, sex, form of ketamine used, reason for exposure, and outcome. RESULTS: A total of 3109 cases were evaluated. 1595 (51%) reported ketamine to be the only substance exposure, while 1514 (49%) involved multiple substances with ketamine. For single agent exposures, more involved males (67%) between the ages of 16-25â¯years (49%). Single agent ketamine exposures peaked between 2000 and 2002, fell consistently until 2008; then rebounded to previous peak levels through 2015. Intentional exposures (65% of all cases) were the most common reason for single agent ketamine exposures. 53% of ketamine-only cases resulted in minor effects, with two deaths. In contrast, ketamine exposures with multiple agents resulted in outcomes judged as moderate or worse in 62% of cases, including 20 deaths. CONCLUSION: Single-agent ketamine exposures reported to US poison centers have rebounded to historical peaks in recent years. More deaths and serious outcomes were reported in ketamine exposures involving multiple substances.

CONTEXT: Prior works demonstrates an increased risk of death when opioid analgesics and benzodiazepines are used concomitantly to gain a high. Using poison center data, we described trends in abuse or misuse of benzodiazepines and opioid analgesics. We quantified mortality risk associated with abuse or misuse of benzodiazepines, opioid analgesics and the combination of opioid analgesics and benzodiazepines. METHODS: This was a retrospective chart review of data from the National Poison Data System which collects information from 55 poison centers located across the United States. We identified reported cases of "intentional abuse or misuse" of benzodiazepine and/or opioid analgesic exposures. Poisson regression was used to compare the number of cases from each year between 2001 and 2014 to the year 2000. Logistic regression was used to determine whether cases exposed to both benzodiazepines and opioids had greater odds of death relative to cases exposed to opioid analgesics alone. RESULTS: From 2000 to 2014, there were 125,485 benzodiazepine exposures and 84,627 opioid exposures among "intentional abuse or misuse" cases. Of the benzodiazepine exposures, 17.3% (n = 21,660) also involved an opioid. In 2010, exposures involving both opioids and benzodiazepines were 4.26-fold (95% CI: 3.87-4.70; p < .001) higher than in 2000. The risk of death was 1.55 (95% CI: 1.01-2.37; p = .04) times greater among those who used both an opioid and a benzodiazepine compared to opioids alone. This association held after adjusting for gender and age. CONCLUSION: Intentional abuse or misuse of benzodiazepines and opioids in combination increased significantly from 2000 to 2014. Benzodiazepine abuse or misuse far exceeded cases of opioid abuse or misuse. Death was greater with co-abuse or misuse of benzodiazepines and opioids. Population-level campaigns to inform the public about the risk of death with co-abuse or misuse of benzodiazepines and opioids are urgently needed to address this overdose epidemic.

OBJECTIVE: To describe current trends in nonopioid substance exposures and associated outcomes among teenagers nationwide. STUDY DESIGN: In this cross-sectional study, we used 2010-2015 data from the American Association of Poison Control Centers' National Poison Data System and Poisson tests to document trends in the rate of calls to poison control centers involving adolescents stratified by sex, exposures by substance category, proportion of intentional exposures, and severity of exposures. RESULTS: The number of calls per 1000 persons increased from 5.7 to 6.8 for teenage girls and decreased from 4.7 to 4.3 for boys. Reported exposures to prescription and over-the-counter medications and illicit street drugs increased between 24% and 73%, and reported opioid exposures decreased by 16%. Among teenage girls, intentional exposures increased from 57% to 68%, with cases increasingly managed in health care facilities and more likely to result in worse health outcomes. CONCLUSIONS: The increase in intentional nonopioid substance exposures among teenage girls, with serious and potentially life-threatening consequences, is a matter of serious concern. Similar trends were not observed among teenage boys.

AIM: To examine temporal trends in accesses to the UK's National Poison Information Service's TOXBASE database in Britain. METHODS: Generalized additive models were used to examine trends in daily numbers of accesses to TOXBASE from British emergency departments between January 2008 and December 2015. Day-of-the-week, seasonality and long-term trends were analysed at national and regional levels (Wales, Scotland and the nine English Government Office Regions). RESULTS: The long-term trend in daily accesses increases from 2.8 (95% confidence interval (CI): 2.6-3.0) per user on 1 January 2008 to 4.6 (95% CI: 4.3-4.9) on 31 December 2015, with small but significant differences in population-corrected accesses by region ( p < 0.001). There are statistically significant seasonal and day of the week patterns ( p < 0.001) across all regions. Accesses are 18% (95% CI: 14-22%) higher in summer than in January and at the weekend compared to weekdays in all regions; there is a 7.5% (95% CI: 6.1-8.9%) increase between Friday and Sunday. CONCLUSIONS: There are consistent in-year patterns in access to TOXBASE indicating potential seasonal patterns in poisonings in Britain, with location-dependent rates of usage. This novel descriptive work lays the basis for future work on the interaction of TOXBASE use with emergency admission of patients into hospital.
