OBJECTIVE: To review pediatric poisonings evaluated at the bedside by medical toxicologists and reported in the ToxIC registry, by sex and age group. METHODS: Pediatric poisoning cases age < /=18 years, reported between January 2010 and December 2016, were reviewed. Descriptive statistics were used to describe study variables by age group and sex. RESULTS: A total of 12,699 cases were analyzed. There were 7517 females and 5182 males. Those < 2 years old represented 12.5% of the study group (n = 1584), 17.2% were 2-6 years old (n = 2178), 8.6% were 7-12 years old (n = 1097), and 61.7% were 13-18 years old (n = 7840). The most common primary reasons for encounter were intentional pharmaceutical with 4900 females and 1836 males; intentional non-pharmaceutical with 952 females and 1213 males; unintentional pharmaceutical with 539 females and 644 males; and unintentional non-pharmaceutical with 435 females and 593 males. Overall, pharmaceuticals were the most commonly involved agents, including analgesics (20.9% of cases) and antidepressants (11% of cases): 27.8% of females and 10.7% of males were reportedly exposed to an analgesic.13.7% of females and 7.0% of males were reportedly exposed to an antidepressant. Among 1584 cases under 2 years, there were 747 females and 837 males; among 2178 cases aged 2-6 years, there were 954 females and 1224 males; among 1097 cases aged 7-12 years, there were 555 females and 542 males; and among 7840 cases aged 13-18 years, there were 5261 females and 2579 males. Death was reported in 0.7% of the cases: 20 females and 18 males. 6.1% of cases were managed with intubation: 421 females and 351 males. CONCLUSIONS: Sex-based characteristics of poisonings varied by age group among pediatric poisoning presentations reported to the ToxIC registry and further research is needed to determine implications for education and prevention efforts.

Background: Variations between male and female populations are previously reported in classes of harmfully used/misused drugs, severity of substance use disorder and risk of relapse. The aim of this study was to provide a review of bedside medical toxicologist managed, sex-specific poisonings in adults that present with harmful drug use/misuse. Methods: ToxIC Registry cases > /=19 and < /=65 years old, with harmful drug use or misuse during the timeframe June 2010-December 2016, were studied. Demographics, primary agents of toxic exposure, administration route and complications were analyzed. Descriptive methods were used in the analysis. Results: The database included 51,440 cases. Of these, 3426 cases were analyzed in which the primary reason for the encounter was harmful substance use/misuse. Females were found to harmfully use/misuse pharmaceutical drugs (N=806, 65.6%) more than nonpharmaceutical drugs (N=423, 34.4%). Males more frequently used nonpharmaceutical drugs (N=1189, 54.1%) than pharmaceutical drugs (1008, 45.9%). Analgesics were used by females (N= 215, 18.2%) and males (N=137, 6.6%). Sedative hypnotics were used by females (N=165, 14%) and males (N=160, 7.8%). Psychoactive agents were used by males (N=325, 15.8%) and females (N=67, 5.7%). Sympathomimetics were used by males (N=381, 18.5%) and females (N=151, 12.8%). The majority of both male and female participants, 1712 (57.9%), utilized an oral route of administration. However, 312 (16.5%) of males utilized inhalation vs 73 (6.8%) of females inhaled their substance. Conclusion: There were sex-specific differences among patients evaluated for harmful substance use/misuse by toxicologists. Considering these differences in regards to management and preventive approaches may be indicated.

INTRODUCTION: The Toxicology Investigator's Consortium (ToxIC) maintains a prospective case registry of all patients that have been managed at the bedside by medical toxicologists. We set out to characterize the differences in toxicological suicide attempts between men and women among adult patients with poisonings managed by medical toxicologists. METHODS: ToxIC database consults for adults aged 19-65 whose primary reasons for encounter were classified as suicide attempt were used for this study (1/2010-12/2016). Data used for analysis included primary agents of toxic exposure, routes of administration, and complications. The statistical analysis was limited to descriptive methods. RESULTS: Out of 51,440 registry cases, 33,259 cases remained for analysis after applying the ages 19-65 and removing those without complete data. Of these, there were 4827 suicide attempts (14.5% of toxicological exposures) which were sub classified by gender. There were more females (F) than males (M) whose toxicology consults were due to suicidal attempts (57.6% versus 42.4%). We also found that more males used alcohol as their primary agent (2.8%M v 1.5%F) or a nonpharmaceutical (%7.4M v %2.3 F). CONCLUSIONS: In our study, we found that there were more females than males who attempted suicide by self-poisoning; and more of them used pharmaceuticals than males. In contrast, a greater number of males used nonpharmaceuticals such as alcohol. We did not find large sex-differences in suicide completion rates, routes of administration, or subsequent symptomologies. In summary, sex-based differences were observed between adult patients with suicidal-intent exposures/ingestions managed at the bedside by medical toxicologists.
