Pediatric water bead-related visits to United States emergency departments.

OBJECTIVE: To evaluate the characteristics and trends of pediatric water bead-related visits to US emergency departments (EDs) using a large national database. METHODS: Data from the National Electronic Injury Surveillance System regarding ED visits by individuals <20 years old associated with water beads from January 1, 2007, through December 31, 2022, were retrospectively analyzed. RESULTS: Based on 307 reported cases, there were an estimated 8159 visits (95% CI: 4447-11,870) to US EDs from 2007 through 2022 involving water beads among <20-year-olds, and more than half (55.0%) of the 307 ED cases involved <5-year-olds. Most cases were treated and released (92.2%), which was consistent across all age groups. The proportion of cases admitted was highest among children <5 years old (10.1%), and this age group accounted for 17 of the 19 admissions (89.5%) in this study. All admissions among children <5 years old involved ingestions. Ingestion was the most common mechanism of injury (45.9%), followed by ear canal insertion (32.6%), nasal insertion (11.7%), and eye injury (8.8%). Although ingestions occurred most frequently among children one (28.4%) and two (23.4%) years of age, children 3 and 4 years old accounted for one-fifth of ingestions. The number of ED cases increased rapidly by 130.9% from 55 cases in 2021 to 127 in 2022. CONCLUSIONS: The number of pediatric water bead-related ED visits is increasing rapidly. Children <5 years old are most commonly involved, usually via water bead ingestion. Increased prevention efforts are needed.

Pediatric Dance-Related Injuries Treated in Emergency Departments in the United States, 2000-2020.

OBJECTIVE: This study investigated the characteristics and trends of children aged 3 to 19 years treated in US emergency departments for dance-related injuries. METHODS: Retrospective analysis of data from the National Electronic Injury Surveillance System from 2000 through 2020 was conducted. RESULTS: An estimated 489,119 children received emergency treatment for a dance-related injury, averaging 23,291 children annually, and the rate of injury increased 68.1% during the 21-year study period. Girls accounted for 80.3% and children aged 15 to 19 years accounted for 46.5% of cases. Sprains/strains were the most frequent diagnosis (44.4%), and lower extremities were the most commonly injured body region (56.4%). Compared with other body regions, patients aged 3 to 10 years were more likely to sustain head/neck injuries (odds ratio, 3.94, 95% confidence interval, 3.42-4.52) than 11- to 19-year-olds. Falls and noncontact mechanisms of injury accounted for 35.6% and 32.1% of injuries, respectively. Unstructured dance activity was associated with 30.8% of dance-related injuries overall and 67.0% among children aged 3 to 5 years. Ballet/pointe dancers frequently sustained lower extremity sprains/strains (39.2%). Compared with other dance types, break dancing was more commonly associated with injuries to an upper extremity than other body regions (odds ratio, 4.76, 95% confidence interval, 3.66-6.19). CONCLUSIONS: The rate of pediatric dance-related injuries treated in US emergency departments is increasing. Unstructured dance activity was an important source of dance-related injury, especially among children aged 3 to 5 years. The injury diagnosis and body region injured varied by child age and type of dance. Additional targeted prevention efforts should be implemented that address the injury characteristics of dancer subgroups.

Suicide-related over-the-counter analgesic exposures reported to United States poison control centers, 2000-2018.

PURPOSE: To investigate suicide-related over-the-counter (OTC) analgesic medication exposures among individuals ≥6 years old reported to United States (US) poison control centers. METHODS: Data from the National Poison Data System for the years 2000-2018 were retrospectively analyzed. RESULTS: From 2000 to 2018, US poison control centers recorded 549 807 suicide-related cases involving OTC analgesics, including 327 781 cases (59.6%) admitted to the hospital and 1745 deaths (0.3%). Most cases involved a single substance (67.5%) and occurred among females (72.7%) and individuals 6-19 years old (49.7%). Overall, the rate of exposures increased significantly by 33.5% from 2000 to 2018, primarily driven by the increasing exposure rate among 6- to 19-year-old females. From 2000 to 2018, exposure rates for acetaminophen and ibuprofen increased, while that for acetylsalicylic acid decreased. Additionally, the proportion of cases resulting in a serious medical outcome or healthcare facility admission increased for all types of OTC analgesics. Acetaminophen and acetylsalicylic acid accounted for 48.0% and 18.5% of cases, respectively, and 64.5% and 32.6% of deaths, respectively. Both acetaminophen and acetylsalicylic acid had greater odds of healthcare facility admission (ORs 2.56 and 2.63, respectively) and serious medical outcomes (ORs 2.54 and 4.90, respectively) compared with ibuprofen. CONCLUSIONS: The rate of suicide-related OTC analgesic cases is increasing. Acetaminophen and acetylsalicylic acid cases are associated with greater morbidity and mortality. Prevention efforts should include implementing unit-dose packaging requirements and restrictions on package sizes and purchase quantities for acetaminophen and acetylsalicylic acid products to reduce access to large quantities of these analgesics.

Differences in Overuse Injuries in Gender-Comparable Sports: A Nationally Representative Sample of High School Athletes.

CONTEXT: Participation in high school sports has physical, physiological, and social development benefits, while also increasing the risk of acute and overuse injuries. Risk of sport-related overuse injury differs between boys and girls. OBJECTIVE: To investigate differences in overuse injuries among US high school athletes participating in the gender-comparable sports of soccer, basketball, and baseball/softball. DESIGN: Descriptive epidemiology study using a nationally representative sample from the High School Reporting Information Online (RIO) database. SETTING: High schools. PATIENTS OR OTHER PARTICIPANTS: Athletes with overuse injuries during the 2006-2007 through 2018-2019 academic years. MAIN OUTCOME MEASURE(S): National estimates and rates of overuse injuries were extrapolated from weighted observed numbers with the following independent variables: sport, gender, academic year, class year, event type, body site, diagnosis, recurrence, activity, and position. RESULTS: Among an estimated 908 295 overuse injuries nationally, 43.9% (n = 398 419) occurred in boys' soccer, basketball, and baseball, whereas 56.1% (n = 509 876) occurred in girls' soccer, basketball, and softball. When comparing gender across sports, girls were more likely to sustain an overuse injury than boys (soccer, injury rate ratio [IRR]: 1.37, 95% CI = 1.20-1.57; basketball, IRR: 1.82, 95% CI = 1.56-2.14; baseball/softball, IRR: 1.21, 95% CI = 1.04-1.41). Most overuse injuries in soccer and basketball for both genders occurred to a lower extremity (soccer: 83.9% [175 369/209 071] for boys, 90.0% [243 879/271 092] for girls; basketball: 77.0% [59 239/76 884] for boys, 80.5% [81 826/101 709] for girls), whereas most overuse injuries in baseball and softball were to an upper extremity (72.5% [81 363/112 213] for boys, 53.7% [73 557/136 990] for girls). For boys' baseball, pitching (43.5% [47 007/107 984]) was the most common activity associated with an overuse injury, which differed from the most common activity of throwing (31.7% [39 921/126 104]) for girls' softball. CONCLUSIONS: Gender differences observed in this study can help guide future strategies that are more specific to gender and sport to reduce overuse injuries among high school athletes.

Gabapentin and pregabalin exposures reported to United States poison centers, 2012-2022.

BACKGROUND: Gabapentin and pregabalin were originally introduced as anticonvulsant medications but are now also prescribed on- and off-label for multiple medical disorders, especially for pain management. The national opioid crisis has led to increased use of non-opioid pain medications, including gabapentinoids, which has been associated with changing patterns of adverse events associated with these medications. This study investigated the characteristics and trends of gabapentin and pregabalin exposures reported to US poison centers from 2012 to 2022. METHODS: National Poison Data System data involving gabapentin and pregabalin exposures for 2012 to 2022 were analyzed. RESULTS: There were 124,161 exposures involving gabapentin and pregabalin as the primary substance reported to US poison centers during the study period. Most exposures involved gabapentin (85.9%), females (59.4%), single-substance exposures (62.9%), or occurred at a residence (97.2%). Suspected suicides accounted for 45.2% of exposures. Most exposures were associated with a minor effect (27.4%) or no effect (34.0%), while 22.1% experienced a serious medical outcome, including 96 fatalities. The rate of gabapentin and pregabalin exposures per one million US population increased by 236.1% from 22.7 in 2012 to 76.5 in 2019 (P < 0.001), followed by a non-significant decrease to 68.5 in 2022 (P = 0.068). CONCLUSIONS: The rate of gabapentin and pregabalin exposures reported to US poison centers increased by more than 230% from 2012 to 2019 before plateauing from 2019 to 2022. The observed rate trend was driven primarily by gabapentin exposures and by cases associated with suspected suicide. Although most exposures were associated with a minor or no effect, 22% of individuals experienced a serious medical outcome, including 96 fatalities. These findings contribute to the discussion of rescheduling gabapentin as a federally controlled substance, which is the current status of pregabalin. Prevention of suicide associated with gabapentin and pregabalin merits special attention.

Glucagon-Like Peptide-1 Receptor Agonist Cases Reported to United States Poison Centers, 2017-2022.

INTRODUCTION: Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are a class of medications for management of diabetes and obesity. The objective of this study is to characterize the epidemiology of GLP-1RA cases reported to US poison centers. METHODS: We analyzed cases involving a GLP-1RA reported to the National Poison Data System during 2017-2022. RESULTS: There were 5,713 single-substance exposure cases reported to US poison centers involving a GLP-1RA. Most cases were among females (71.3%) and attributable to therapeutic errors (79.9%). More than one-fifth (22.4%) of cases were evaluated in a healthcare facility, including 0.9% admitted to a critical care unit and 4.1% admitted to a non-critical care unit. Serious medical outcomes were described in 6.2% of cases, including one fatality. The rate of cases per one million US population increased from 1.16 in 2017 to 3.49 in 2021, followed by a rapid increase of 80.9% to 6.32 in 2022. Trends for rates of serious medical outcomes and admissions to a healthcare facility showed similar patterns with 129.9% and 95.8% increases, respectively, from 2021 to 2022. CONCLUSIONS: Most GLP-1RA cases reported to US poison centers were associated with no or minimal effects and did not require referral for medical treatment; however, a notable minority of individuals experienced a serious medical outcome or healthcare facility admission. The rate of reported cases increased during the study period, including an 80.9% increase from 2021 to 2022. Opportunities exist to improve provider and patient awareness of the adverse effects of these medications.

Consumer Product-Related Pediatric Eye Injuries Treated in United States Emergency Departments.

PURPOSE: This study investigates characteristics and trends of children <18 years old treated in United States emergency departments (EDs) for consumer product-related eye injuries. METHODS: Data from the National Electronic Injury Surveillance System for January 1, 1997 through December 31, 2019 were analyzed. RESULTS: During the 23-year study period, an estimated 1,453,283 children were treated for consumer product-related eye injuries, averaging 63,186 children annually. Overall, the eye injury rate per 100,000 children <18 years old increased initially from 82.64 in 1997 to 104.53 in 2001 (p = .0492) and then decreased by 32.1% to 70.95 in 2019 (p < .0001). Almost two-thirds (64.5%) were boys and 32.1% were <5 years old. Overall, 2.6% of patients were admitted, but injuries involving non-powder firearms and golf had the highest admission rates (18.8% and 14.7%, respectively). Compared with other product categories, children were more frequently admitted if they had an eye injury associated with non-powder firearms (18.8% admitted; OR: 10.92, 95% CI: 8.67-13.76) or golf (14.7% admitted; OR: 6.59, 95% CI: 3.51-12.34). Contact with a non-chemical product was the leading mechanism of eye injury in all age groups, except children <5 years old, in which the leading mechanism was contact with a chemical product (34.2%). Corneal abrasion (36.5% overall) was the most frequent diagnosis across all age groups. CONCLUSIONS: Although the rate of consumer product-related pediatric eye injuries treated in US EDs has decreased since 2001, these injuries remain common among children. Therefore, increased prevention efforts are needed.

Caregivers' Perceptions of Child Trauma Symptomatology, Stress, and Child Abuse Disclosures.

Caregivers consider child abuse disclosures stressful life events, but research has not investigated whether this stress affects caregiver ratings of child trauma symptomatology. Secondary data from a Child Advocacy Center in the Midwestern United States between the period of January 1, 2018, and April 31, 2019, stepwise logistic regression models, and change in estimate calculations were used to assess (1) the relationship between child abuse disclosure(s) and caregiver stress and (2) the association between caregiver stress disclosure and clinically significant ratings on the Trauma Symptom Checklist for Young Children (TSCYC). While a child's physical abuse disclosure was associated with caregiver stress and caregiver stress was significantly associated with clinically significant ratings for child depression and anger/aggression TSCYC scales, abuse disclosure did not affect the relationship between caregiver stress and TSCYC scale ratings. Moving forward, caregiver-reported stress should be considered when utilizing caregiver-completed child trauma symptom screens.

Child maltreatment among victims of violent death: an analysis of national violent death reporting system data, 2014-2018.

BACKGROUND: Limited information is known about the impact of childhood maltreatment on lifetime risk of violent death. This study aimed to compare manner of death, demographics, age at time of death, and the presence of a mental health or substance use disorder among decedents of violent deaths with a history of child maltreatment to those without. METHODS: This cross-sectional study compared characteristics of pediatric and adult violent deaths with and without a history of child maltreatment that were captured in the National Violent Death Reporting System from 2014 through 2018. RESULTS: Decedents who were male, multiracial, and had adulthood substance or mental health disorders were more likely to have a history of maltreatment. All-age decedents with a history of maltreatment were more likely to die by homicide. Adult decedents with a history of maltreatment were more likely to die by suicide. Maltreated decedents died significantly younger than non-maltreated decedents. CONCLUSIONS: Among victims of violent deaths, an identified history of child maltreatment was associated with increased risk of homicide across the lifespan, adult suicide, and earlier death. A history of child maltreatment was also associated with mental health and substance use disorders, which may reflect one of the pathways through which the child maltreatment-to-death association functions.

Longitudinal trends in liquid laundry detergent packet exposures: 2014-2022.

BACKGROUND: Liquid laundry detergent packet exposures modestly declined in the mid-2010s among children less than 6 years of age due to public awareness and voluntary product safety standards. We aimed to assess longitudinal trends in the number and rate of liquid laundry detergent packet exposures in the United States by age. METHODS: Data from the National Poison Data System were analyzed to characterize liquid laundry detergent packet exposures between January 2014 and December 2022. RESULTS: From 2014-2022, there were 114,826 single and polysubstance exposures to liquid laundry detergent packets. Children less than 6 years of age (86.8 percent) were most commonly exposed. When evaluating multi-year trends, we found that the annual exposure rate per 1 million children less than 6 years old increased by 16.8 percent from 392.6 in 2018 to 458.7 in 2020. Subsequently, the annual exposure rate in children less than 6 years of age declined by 6.8 percent from 2020 to 2022 (427.4 exposures per 1 million). The annual rate of adolescent exposures increased by 85.4 percent from 2014 (4.1 exposures per 1 million) to 2017 (7.6 exposures per 1 million), with a subsequent increase of 155.3 percent from 2017 to 2018 (19.4 exposures per 1 million). Among adults, the annual exposure rate increased by 147.1 percent from 2014 (1.7 exposures per 1 million) to 2022 (4.2 exposures per 1 million). The number of more serious medical outcomes and hospital admissions among children less than 6 years of age declined by 44.3 percent and 68.6 percent, respectively, between 2014 and 2018. CONCLUSIONS: Despite declines in the number, rate, and severity of liquid laundry detergent packet exposures among children less than 6 years old, the exposure burden remains high. Additionally, exposures have increased among older children, adolescents, and adults. Renewed safety efforts are warranted to protect prior public health gains and further reduce exposures.

Hydrocarbon ingestions among individuals younger than 20 years old reported to United States Poison Centers, 2000-2021.

BACKGROUND: Hydrocarbon-based products have many household and commercial uses and exposure to these substances is common. Severe clinical effects can occur if these products are ingested. This study investigated the characteristics and trends of hydrocarbon ingestions reported to United States Poison Centers. METHODS: Data from the National Poison Data System were analyzed for cases of hydrocarbon ingestion among individuals < 20 years old reported to United States Poison Centers from January 1, 2000 through December 31, 2021. RESULTS: There were 284,085 hydrocarbon ingestions reported during the 22-year study period in which a hydrocarbon was the first-ranked substance. Most of these cases occurred among children < 6 years old (83.2%), males (64.6%), at a residence (96.5%), were single-substance exposures (98.3%), and were managed on-site rather than in a health care facility (74.9%). However, 4.5% of cases were associated with a serious medical outcome, including 34 deaths. Thirty-two deaths were among children < 6 years old and most were associated with aspiration. Gasolines accounted for 24.6% of total cases, followed by lubricating oils and/or motor oils (19.9%), other types of hydrocarbons (14.9%), lamp oils (11.3%), and lighter fluids and/or naphtha (10.3%). The rate of hydrocarbon ingestions among United States youth < 20 years old decreased significantly (p < 0.0001) by 66.5% from 2000 to 2021. The greatest rate decrease was observed among lamp oils (- 78.4%, p < 0.0001), followed by gasolines (- 75.9%, p < 0.0001). CONCLUSIONS: Although the rate of hydrocarbon ingestions decreased during the study period and most reported cases resulted in non-serious outcomes, the number of cases remains high with a non-trivial minority (4.5%) of cases associated with a serious medical outcome, including death. Most deaths were among children < 6 years old. This underscores the need to increase primary prevention efforts, especially for young children.

Pediatric Suspected Suicides and Nonfatal Suicide Attempts Reported to United States Poison Control Centers Before and During the COVID-19 Pandemic.

INTRODUCTION: This study investigated the characteristics and compared the trends of pediatric suspected suicide and nonfatal suicide attempts reported to United States (US) poison control centers (PCCs) before and during the first year of the COVID-19 pandemic. METHODS: An interrupted time series analysis using an ARIMA model was conducted to evaluate the trends of suspected suicides and nonfatal suicide attempts among children 6-19 years old reported to the National Poison Data System during March 2020 through February 2021 (pandemic period) compared with March 2017 through February 2020 (pre-pandemic period). RESULTS: The annual number of cases of suspected suicides and nonfatal suicide attempts increased by 4.5% (6095/136,194) among children 6-19 years old during March 2020 through February 2021 compared with the average annual number during the previous three pre-pandemic years. There were 11,876 fewer cases than expected from March 2020 to February 2021, attributable to a decrease in cases during the initial three pandemic months. The average monthly and average daily number of suspected suicides and nonfatal suicide attempts among children 6-12 years old and 13-19 years old was higher during school months than non-school months and weekdays than weekends during both the pre-pandemic and pandemic periods. CONCLUSIONS: There was a greater than expected decrease in the number of suspected suicides and nonfatal suicide attempts among children 6-19 years old reported to US PCCs during the early pandemic months, followed by an increase in cases. Recognizing these patterns can help guide an appropriate public health response to similar future crises.

Inhalant misuse reported to America's Poison Centers, 2001-2021.

CONTEXT/OBJECTIVE: This study investigated characteristics and trends of inhalant misuse reported to United States poison centers from 2001 through 2021. METHODS: Using data from the National Poison Data System and the United States Census Bureau, analyses were conducted of demographic and other characteristics, inhalant category, level of health care received, and medical outcome, and population-based rate trends were assessed. RESULTS: United States poison centers managed 26,446 inhalant misuse cases from 2001 through 2021, which equaled an annual average of 1,259 cases. Most inhalant misuse involved males (73.0%) or a single substance (91.0%). Teenagers accounted for 39.7% of cases. Among inhalant misuse cases, 41.4% were associated with a serious medical outcome and 27.7% were admitted to a healthcare facility. Overall, the rate of inhalant misuse per 1,000,000 United States population increased by 9.6% (P = 0.0031) from 5.33 in 2001 to 5.84 in 2010, followed by a decrease to 2.60 (-55.5%, P < 0.001) in 2021. "Freon and other propellants" showed the largest change in rate, increasing from 1.28 in 2001 to 3.55 in 2010 (P < 0.001), before decreasing to 1.36 in 2021 (P < 0.001). This trend was driven by the 13-19-year-old age group, and the trend reversal in 2010 among teenagers coinciding with an almost complete ban on FreonTM by the United States Environmental Protection Agency, which it implemented under the Clean Air Act. CONCLUSIONS: Although the annual rate of inhalant misuse reported to United States poison centers has been decreasing since 2010, it remains an important public health problem. The United States Environmental Protection Agency's 2010 regulation of FreonTM may have been an important contributor to the dramatic trend reversal and decrease in inhalant misuse rates starting in that year. This may exemplify the potential effect that regulatory efforts can have on public health.

Age-Dependent Responsiveness to Smoke Alarm Signals Among Children.

OBJECTIVES: Although it has been established that smoke alarms have more difficulty awakening children from sleep than adults, no attempt has been previously made to characterize how smoke alarm responsiveness changes with age during childhood. The objective of this study is to evaluate the age-dependent responsiveness to various smoke alarm signals among children 5 to 12 years old. METHODS: The effect of age on children's response to 4 types of smoke alarms (human voice, hybrid voice-tone, low-frequency tone, and high-frequency tone) was evaluated using combined data from 3 previous studies. RESULTS: There were 540 subjects (median age 9 years; 51.7% male). The proportion of children who awakened demonstrated a statistically significant (P < .001) increase of 3.1% to 7.6% for each additional year of age between 5 and 12 years old for the 4 alarm types. Similarly, child age showed a statistically significant (P < .001) effect on the proportion who escaped for each of the 4 alarm types. The proportion of subjects who awakened or escaped did not differ significantly by sex for any of the alarm types. Median time-to-awaken and median time-to-escape decreased with increase in child age for all alarm types. CONCLUSIONS: This study demonstrates the substantial influence of child age on the effectiveness of audible smoke alarms during childhood. Among 12-year-olds, only 56.3% escaped within 1 minute (and 67.6% within 2 minutes) to a high-frequency tone. However, a hybrid voice-low-frequency tone alarm is >96% effective at awakening and prompting escape within 1 minute among children 9 years and older.

Epidemiological Comparison of ACL Injuries on Different Playing Surfaces in High School Football and Soccer.

Background: Anterior cruciate ligament (ACL) injuries are among the most common serious injuries to athletes in the United States. Among high school sports, the highest rates of ACL injury occur in soccer and football. Purpose: To compare ACL injuries on artificial turf and natural grass using a nationally representative sample of high school athletes participating in football and boys' and girls' soccer. Study Design: Descriptive epidemiology study. Methods: ACL injuries among high school athletes participating in football and soccer were obtained from the High School Reporting Information Online surveillance system during the 2007-08 through 2018-19 school years. National estimates and injury proportion ratios (IPRs) with 95% CIs were calculated for ACL injuries that occurred on artificial turf versus natural grass. Results: A total of 1039 ACL injuries were reported, which represented an estimated 389,320 (95% CI, 358,010-420,630) injuries nationally. There were 74,620 estimated football-related ACL injuries on artificial turf and 122,654 on natural grass. Likewise, 71,877 of the estimated soccer-related ACL injuries occurred on artificial turf and 104,028 on natural grass. A contact-injury mechanism accounted for 50.2% of football-related ACL injuries on artificial turf and 60.8% on natural grass. For soccer-related ACL injuries, a noncontact mechanism predominated on artificial turf (61.5%) and natural grass (66.4%). Among all injuries, ACL injuries were more likely to occur on artificial turf than natural grass in both football (IPR, 1.23 [95% CI, 1.03-1.47]) and girls' soccer (IPR, 1.53 [95% CI, 1.08-2.16]); however, no significant association was found in boys' soccer (IPR, 1.65 [95% CI, 0.99-2.75]). Among lower extremity injuries, ACL injuries were more likely to occur on artificial turf than natural grass in both boys' soccer (IPR, 1.72 [95% CI, 1.03-2.85]) and girls' soccer (IPR, 1.61 [95% CI, 1.14-2.26]); however, the association was not significant in football (IPR, 1.17 [95% CI, 0.98-1.39]). Conclusion: ACL injuries were more likely to occur (ie, had larger IPRs) on artificial turf than natural grass; however, this relationship was not statistically significant for all sports.

Pediatric poison exposures reported to United States poison centers before and during the COVID-19 pandemic.

OBJECTIVE: To assess the association of the COVID-19 pandemic with pediatric poison exposures with a focus on unintentional exposures associated with exploratory behavior among children <6 years old. METHODS: An interrupted time series analysis was conducted to evaluate the association of the pandemic with poison exposures among youth <20 years old. Exposures reported to US poison centers (PCs) from 1 March 2017 through 28 February 2020 (pre-pandemic) compared with 1 March 2020 through 28 February 2021 (pandemic) were analyzed. RESULTS: From March 2017 through February 2021, there were 5,244,684 exposures reported to US PCs involving youth <20 years old. There was a 6.0% decrease in poison exposures among youth <20 years old reported to US PCs from pre-pandemic (annual average) to pandemic periods, and there were 93,336 (95% CI: 92,738-93,937) fewer exposures than expected among these individuals during March 2020 through February 2021. Unintentional poison exposures associated with exploratory behavior among children <6 years old accounted for 91.4% of exposures in this age group, and although there were 17,207 (95% CI: 16,951-17,466) fewer of these exposures than expected during the pandemic period, these exposures initially increased during the first two months of the pandemic before decreasing. CONCLUSIONS: The COVID-19 pandemic was associated with changes in poison exposure patterns among youth <20 years old, resulting in a decrease in the number of exposures reported to US PCs during the first pandemic year. Exposure patterns changed with progression from the initial months of the pandemic to later months and varied by age group and reason for exposure. Unintentional poison exposures associated with exploratory behavior among children <6 years demonstrated an increase during the initial first two months of the pandemic before decreasing. Understanding these patterns will help guide an appropriate response to similar future public health events.

An epidemiologic comparison of acute and overuse injuries in high school sports.

BACKGROUND: Acute and overuse injuries affect millions of high school athletes annually and a better understanding of differences between these injuries is needed to help guide prevention, treatment, and rehabilitation strategies. This study compares acute and overuse injuries using a nationally representative sample of high school athletes. METHODS: Injuries among United States high school athletes participating in 5 boys' sports (football, soccer, basketball, wrestling, baseball) and 4 girls' sports (soccer, volleyball, basketball, softball) reported in the High School RIO™ surveillance system during the 2006-07 through 2018-19 school years were classified as acute or overuse. National estimates and injury rates were calculated. RESULTS: Of 17 434 646 estimated injuries, 92.0 % were acute and 8.0 % were overuse. The acute injury rate was higher than the overuse injury rate among both male (Rate Ratio [RR] 16.38, 95 % CI: 15.70-17.10) and female (RR 8.14, 95 % CI: 7.71-8.60) athletes. The overuse injury rate per 10,000 athlete exposures among female athletes (1.8) was slightly higher than among males (1.4). The rate of acute injury compared with the rate of overuse injury was higher during competition (RR 32.00, 95 % CI: 29.93-34.22) than practice (RR 7.19, 95 % CI: 6.91-7.47). Boys' football contributed the most acute (42.1 %) and overuse (23.7 %) injuries among the 9 sports. Among female sports, girls' soccer contributed the most acute (15.6 % of all acute injuries) and overuse (19.4 % of all overuse injuries) injuries. The lower extremity was most commonly injured in acute (48.9 %) and overuse (65.9 %) injuries. Ligament sprain (31.7 %) and concussion (21.0 %) were the most common acute injury diagnoses, while muscle strain (23.3 %) and tendonitis (23.2 %) were the most common overuse injury diagnoses. Compared with acute injuries, overuse injuries were more likely to result in time loss from sports participation of < 1 week among both boys and girls and across most sports. Acute injuries were more likely than overuse injuries to cause a time loss of 1-3 weeks or medical disqualification from sports participation. CONCLUSIONS: Acute and overuse injuries display many differences that provide opportunities for data-informed athlete preparation, treatment, and rehabilitation, which may reduce injuries and improve injury outcomes in high school athletics.

Optimizing smoke alarm signals: Testing the effectiveness of children's smoke alarms for sleeping adults.

BACKGROUND: Being asleep is an important risk factor for death during a residential fire; however, the high-frequency tone smoke alarms in many homes will not adequately awaken children who are old enough to self-rescue. In a series of previous studies, we identified smoke alarm signals that effectively awaken children 5-12 years old and prompt their escape. Because it is impractical to have separate alarms for children and adults in a household, the purpose of this study is to test whether alarms that are effective in awakening children and prompting their escape are also effective among adults. METHODS: Using a randomized, non-blinded, repeated measures design, 150 adults 20-49 years old were exposed during stage 4 sleep to four different smoke alarms. Statistical tests included the Kaplan-Meier estimator, generalized Wilcoxon test, and hazard ratios with Wald's 95% confidence intervals. RESULTS: The median age of study subjects was 30.0 years and 67.3% were female. Almost all (n = 149) subjects awakened and performed the escape procedure to all four alarms; one individual did not awaken or escape to the high-frequency tone alarm. The median time-to-awaken was 2.0 s for the high-frequency tone alarm and 1.0 s for the other three alarms. The median time-to-escape for the high-frequency tone alarm was 12.0 s, compared with 10.0 s for the low-frequency tone alarm and 9.0 s each for the female and male voice alarms. All pairwise comparisons between the high-frequency tone alarm and each of the other three alarms were statistically significant for the probability functions for time-to-awaken and time-to-escape. There were no significant differences in these outcome measures between the latter three alarms, except for female voice versus low-frequency tone alarms for time-to-escape. CONCLUSIONS: All alarms performed well, demonstrating that smoke alarms developed for the unique developmental requirements of sleeping children are also effective among sleeping adults. Compared with a high-frequency tone alarm, use of these alarms may reduce residential fire-related injuries and deaths among children, while also successfully alerting adult members of the household.

Nonfatal All-Terrain Vehicle-Related Head and Neck Injuries to Children Treated in US Emergency Departments.

This study investigates children <18 years old with nonfatal all-terrain vehicle (ATV)-related head and neck injuries treated in United States emergency departments by analyzing data from the National Electronic Injury Surveillance System from 1990 to 2014. An estimated 279 391 children received emergency treatment during the 25-year study period. The number of injuries remained relatively constant from 1990 to 1997, increased by 142.9% from 1997 to 2007, and then decreased by 37.4% from 2007 to 2014. The most common diagnoses were concussion/closed head injury (32.6%) and fracture (32.6%); 15.4% of children were admitted. The most common injury mechanisms include ejection (30.0%), crash (18.8%), and rollover (15.8%). Patients who were injured on a street/highway were 1.49 times (95% confidence interval = 1.11-1.99) more likely to be admitted than patients injured at other locations. Although the number of nonfatal ATV-related head and neck injuries decreased during the latter part of the study period, they remain common and can have serious medical outcomes.

Children With Facial Burns Treated in United States Emergency Departments, 2000 to 2018.

OBJECTIVE: To investigate the characteristics and trends of facial burns among children. METHODS: Data from the National Electronic Injury Surveillance System database were retrospectively analyzed for children <20 years old treated in United States (US) emergency departments (EDs) from 2000 to 2018 and national facial burn estimates were calculated. RESULTS: During 2000 to 2018, there were an estimated 203,180 children <20 years old treated in US EDs for facial burns, averaging 10,694 burns or 130 burns per million children annually. Boys accounted for 66.4% of cases, and 41.9% were patients <5 years old. The most common type of burn was thermal (51.9%), followed by scalds (30.7%). The 2 most common injury mechanisms were light/lit (22%) and spilled/splashed (15.1%). Fuels and fuel burning equipment (13.1%) were most commonly associated with burns. Overall, the number of facial burns decreased significantly by 53.1% during the 19-year study period with 6525 cases treated in 2018. Although the number of thermal and radiation burns decreased significantly by 69.6% and 63.5%, respectively, the number of scald burns remained relatively constant. CONCLUSIONS: Although the number of children treated in US EDs for facial burns decreased significantly from 2000 to 2018, these injuries remain common. Contrary to the observed decline in thermal and radiation burns, scald burns did not demonstrate a significant temporal trend. These findings indicate a need for increased prevention efforts, especially focused on scalds. Because the type of burn, mechanisms involved, and consumer products associated with facial burns vary by age group, prevention strategies should be developmentally tailored.
