Association between headache and suicidality: An analysis of universal suicide screening data at a large urban county hospital.

BACKGROUND: Identifying individuals at increased risk of suicide is important, particularly those who present for treatment for nonpsychiatric chief complaints who may go undetected. It has been found that pain symptoms, such as headache, are associated with suicide, although this association requires further characterization. This study examined specific components of suicidality in relation to headache subtypes. METHODS: This study retrospectively reviewed 2,832,835 nonpsychiatric adult clinical encounters at a large county hospital, where a standardized suicide risk screening tool, the Columbia-Suicide Severity Rating Scale (C-SSRS), was universally implemented. The C-SSRS assesses specific components of suicidality: wish to be dead and suicidal ideation, method, intent, plan, and action. Multivariate logistic regressions were performed to assess the association between headache, as well as headache subtype (migraine, tension, or cluster), and each component of suicidality. RESULTS: There were significant positive associations between presenting with a headache and 2 specific components of suicidality: wish to be dead and suicidal action. Individuals with tension headache may have a lower risk of wishing to be dead compared to those with migraine and cluster headaches. CONCLUSIONS: The association of headaches with specific elements of sui-cidality demonstrates the potential yield of identification of suicide risk among individuals with nonpsychiatric presentations.

Sex- and Age-specific Increases in Suicide Attempts by Self-Poisoning in the United States among Youth and Young Adults from 2000 to 2018.

OBJECTIVE: To evaluate the incidence and outcomes from intentional suspected-suicide self-poisoning in children and young adults ages 10-24 years old from 2000 to 2018. STUDY DESIGN: Retrospective review of intentional suspected-suicide self-poisoning cases reported to the National Poison Data System from US poison centers from 2000 to 2018 for patients 10-24 years old. For comparison of annual rates, population data by year of age were obtained from the US Census Bureau. We evaluated changes in the annual incidence, the annual rate per 100 000 population, and the medical outcome by patient age and sex. RESULTS: There were 1 627 825 intentional suspected-suicide self-poisoning cases, of which 1 162 147 (71%) were female. In children 10-15 years old from 2000 to 2010, there was a decrease in number and rate per 100 000 population followed by a significant increase (from 125% to 299%) from 2011 to 2018. In children 10-18 years old, the increase from 2011 to 2018 was driven predominantly by females. In 19-24 years old age groups, there was a temporal delay and reduced increase in slope compared with the younger groups. There were 340 563 moderate outcomes, 45 857 major outcomes, and 1404 deaths. The percentage of cases with a serious outcome, major effect, or death increased over time and with age. CONCLUSIONS: The incidence and rate of suicide attempts using self-poisoning in children less than 19 years old increased significantly after 2011, occurring predominantly in young girls. There has been an increase in the severity of outcomes independent of age or sex.

Evaluation of toxicity after acute accidental methotrexate ingestions in children under 6 years old: a 16-year multi-center review.

CONTEXT: There is little data on the frequency of adverse events following acute methotrexate ingestions in pediatric patients. Likewise, recommendations for observation length, site and management strategies in this population are not well established. Therefore, most recommendations are modeled after management of chronic overdose in patients with underlying medical conditions. OBJECTIVE: The primary objective of this study is to determine the frequency of acute toxicity after acute methotrexate accidental unsupervised ingestions in patients less than six years. In addition, we describe the frequency of late toxicity and characterize the management site and approaches. MATERIALS AND METHODS: This is a retrospective cohort study of pediatric accidental unsupervised methotrexate ingestions reported to six poison centers in the United States over a 16 year period. Demographic information, exposure details, signs, symptoms, treatments, length and location of observation and outcomes were collected. RESULTS: 103 patients met inclusion criteria. Methotrexate dose was reported in 86 patients (84%) and ranged from 1.3 mg-75 mg. The majority of cases (97%) ingested a dose ≤20 mg. The significant majority of cases experienced no clinical effects (99 of 103 cases; 96%). Three children experienced minor outcome (3%). There were no patients with a major outcome or death. CONCLUSIONS: The incidence of toxicity from pediatric single, acute ingestions of methotrexate is rare and when it occurs is generally limited to no or only minimally concerning effects. Because concentrations from single ingestions were consistent with low subtoxic exposures, we believe that home monitoring without hospital referral and without methotrexate specific therapy is reasonable in those with acute ingestions up to 20 mg.
