Identification and initial management of intoxication by alcohol and other drugs in the pediatric emergency room / Identificação e manejo inicial de intoxicações por álcool e outras drogas na sala de emergência pediátrica

Abstract Objective: To review the screening, diagnosis, evaluation, and treatment of intoxication by alcohol and other drugs in children and adolescents in the emergency scenario. Data source: This was a narrative literature review. Data summary: The detection of this problem in the emergency room can be a challenge, especially when its assessment is not standardized. The intentional and episodic use of large amounts of psychoactive substances by adolescents is a usual occurrence, and unintentional intoxication is more common in children younger than 12 years. The clinical picture in adolescents and children differs from that in adults and some particularities are important in the emergency scenario. After management of the acute condition, interventions targeting the adolescent at risk may be effective. Conclusion: The diagnosis and treatment of intoxication by alcohol and other drugs in adolescents and children in the emergency scenario requires a systematic evaluation of the use of these drugs. There are few specific treatments for intoxication, and the management comprehends support measures and management of related clinical complications.

Resumo Objetivo: Revisar o rastreamento, o diagnóstico, a abordagem e o tratamento das intoxicações por álcool e outras drogas de crianças e adolescentes no contexto de emergência. Fontes dos dados: Foi feita uma revisão narrativa da literatura. Sumário dos achados: A detecção desse problema na sala de emergência pode ser um desafio, especialmente quando sua avaliação não é padronizada. O uso intencional e em grandes quantidades episódicas de substâncias psicoativas é o padrão em adolescentes e a intoxicação não intencional é mais comum em crianças menores de 12 anos. O quadro clínico em adolescentes e em crianças difere dos adultos e algumas particularidades são importantes no contexto de emergência. Após o manejo do quadro agudo, intervenções com vistas ao adolescente de risco podem ser efetivas. Conclusão: O diagnóstico e o tratamento das intoxicações por álcool e outras drogas em adolescentes e crianças em emergência requer uma avaliação sistemática do uso dessas drogas. Há poucos tratamentos específicos para intoxicação e o manejo é de apoio e das complicações clínicas relacionadas.

High rates of relapse in adolescents crack users after inpatient clinic discharge / Alto índice de recaída em adolescentes usuários de crack após a alta da internação

ABSTRACT Objective The objective of the present study was to evaluate 88 adolescent crack users referred to hospitalization and to follow them up after discharge to investigate relapse and factors associated with treatment. Methods Cohort (30 and 90 days after discharge) from a psychiatric hospital and a rehab clinic for treatment for chemical dependency in Porto Alegre between 2011 and 2012. Instruments: Semi-structured interview, conducted to evaluate the sociodemographic profile of the sample and describe the pattern of psychoactive substance use; Crack Use Relapse Scale/CURS; Questionnaire Tracking Users to Crack/QTUC; K-SADS-PL. Results In the first follow-up period (30 days after discharge), 65.9% of participants had relapsed. In the second follow-up period (90 days after discharge), 86.4% of participants had relapsed. Conclusion This is one of the first studies that show the extremely high prevalence of early relapse in adolescent crack users after discharge, questioning the cost/benefit of inpatient treatment for this population. Moreover, these results corroborate studies which suggested, young psychostimulants users might need tailored intensive outpatient treatment with contingency management and other behavioral strategies, in order to increase compliance and reduce drug or crime relapse, but this specific therapeutic modality is still scarce and must be developed in Brazil.

RESUMO Objetivo O objetivo do presente estudo foi avaliar 88 adolescentes usuários de crack no que se refere à hospitalização e dar-lhes seguimento após a alta, para investigar as recaídas e os fatores associados ao tratamento. Métodos Coorte (30 e 90 dias após a alta) de um hospital psiquiátrico e uma clínica de reabilitação, para o tratamento de dependência química em Porto Alegre, entre 2011 e 2012. Instrumentos: entrevista semiestruturada, realizada para avaliar o perfil sociodemográfico da amostra e descrever o padrão de uso de substâncias psicoativas; Escala de Recaída dos Usuários de Crack/ERUC; Questionário de Seguimento de Usuários de Crack/QSUC; K-SADS-PL. Resultados No primeiro período de seguimento (30 dias após a alta), 65,9% dos participantes recaíram. No segundo período de seguimento (90 dias após a alta), 86,4% dos participantes tiveram recaíram. Conclusão Este é um dos primeiros estudos que mostram a prevalência extremamente alta de recaída precoce em adolescentes usuários de crack após a alta, questionando o custo-benefício do tratamento em regime de internação para essa população. Além disso, esses resultados corroboram estudos que sugerem que usuários de psicoestimulantes jovens podem precisar de um adaptado Tratamento Ambulatorial Intensivo, com manejo de contingências e outras estratégias comportamentais, a fim de aumentar a adesão, reduzir o uso da droga ou recaída ao crime. No entanto, essa modalidade terapêutica específica ainda é escassa e deve ser desenvolvida no Brasil.

IL-6 and IL-10 levels in the umbilical cord blood of newborns with a history of crack/cocaine exposure in utero: a comparative study / Níveis de IL-6 e IL-10 no sangue de cordão umbilical de recém-nascidos com história de exposição intrauterina ao crack/cocaína: um estudo comparativo

Introduction Prenatal cocaine exposure (PCE) is associated with neurobehavioral problems during childhood and adolescence. Early activation of the inflammatory response may contribute to such changes. Our aim was to compare inflammatory markers (IL-6 and IL-10) both in umbilical cord blood and in maternal peripheral blood at delivery between newborns with history of crack/cocaine exposure in utero and non-exposed newborns. Methods In this cross-sectional study, 57 newborns with a history of crack/cocaine exposure in utero (EN) and 99 non-exposed newborns (NEN) were compared for IL-6 and IL-10 levels. Sociodemographic and perinatal data, maternal psychopathology, consumption of nicotine and other substances were systematically collected in cases and controls. Results After adjusting for potential confounders, mean IL-6 was significantly higher in EN than in NEN (10,208.54, 95% confidence interval [95%CI] 1,328.54-19,088.55 vs. 2,323.03, 95%CI 1,484.64-3,161.21; p = 0.007; generalized linear model [GLM]). Mean IL-10 was also significantly higher in EN than in NEN (432.22, 95%CI 51.44-812.88 vs. 75.52, 95%CI 5.64-145.39, p = 0.014; GLM). Adjusted postpartum measures of IL-6 were significantly higher in mothers with a history of crack/cocaine use (25,160.05, 95%CI 10,958.15-39,361.99 vs. 8,902.14, 95%CI 5,774.97-12,029.32; p = 0.007; GLM), with no significant differences for IL-10. There was no correlation between maternal and neonatal cytokine levels (Spearman test, p ≥ 0.28 for all measures). Conclusions IL-6 and IL-10 might be early biomarkers of PCE in newborns. These findings could help to elucidate neurobiological pathways underlying neurodevelopmental changes and broaden the range of possibilities for early intervention.

Introdução A exposição pré-natal à cocaína está associada a problemas neurocomportamentais durante a infância e adolescência. A ativação precoce da resposta inflamatória pode contribuir para tais alterações. Nosso objetivo foi comparar marcadores inflamatórios (IL-6 e IL-10) no sangue do cordão umbilical e no sangue periférico materno na hora do parto, entre recém-nascidos expostos ao crack intraútero e recém-nascidos não expostos. Métodos Neste estudo transversal, 57 recém-nascidos expostos ao crack intraútero (RNE) e 99 recém-nascidos não expostos (RNNE) foram comparados quanto aos níveis de IL-6 e IL-10. Dados sociodemográficos e perinatais, psicopatologia materna, consumo de nicotina e outras substâncias foram sistematicamente coletados em casos e controles. Resultados Após o ajuste para potenciais confundidores, a média de IL-6 foi significativamente maior nos RNE em comparação aos RNNE [10.208,54, intervalo de confiança (IC95%) 1.328,54-19.088,55 versus2.323,03, IC95% 1.484,64-3.161,21; p = 0,007; modelo linear generalizado (MLG)]. A média ajustada de IL-10 foi significativamente maior nos RNE do que nos RNNE (432,2189, IC95% 51,44-812,88 versus 75,52, IC95% 5,64-145,39, p = 0,014; MLG). Medidas pós-parto ajustadas de IL-6 foram significativamente maiores nas mães que usaram de crack/cocaína (25.160,05, IC95% 10.958,15-39.361,99 versus 8.902,14, IC95% 5.774,97-12.029,32; p = 0,007; MLG), sem diferenças significativas para IL-10. Não houve correlação entre níveis maternos e neonatais de citocinas (teste de Spearman, p ≥ 0,28 para todas as medidas). Conclusões IL-6 e IL-10 podem ser biomarcadores precoces da exposição pré-natal a cocaína em recém-nascidos. Esses resultados podem ajudar a elucidar as vias neurobiológicas subjacentes a alterações do desenvolvimento e aumentar a gama de possibilidades para intervenção precoce.

Cost-utility analysis of methylphenidate treatment for children and adolescents with ADHD in Brazil

Objective: To perform a cost-utility analysis on the treatment of attention deficit hyperactivity disorder (ADHD) with methylphenidate immediate-release (MPH-IR) in children and adolescents from Brazil. Method: A Markov model was constructed to compare MPH-IR vs. no treatment. A 24-week naturalistic study was conducted to collect transition probabilities and utility data. Effectiveness was expressed as quality-adjusted life-years (QALY), and costs reported in 2014 international dollars (I$). The perspective was the Brazilian Unified Health System as payer, and the time horizon was 6 years. Results: Of 171 patients, 73 provided information at baseline, and 56 at week 24. Considering the MPH-IR monthly cost of I$ 38, the incremental cost-effectiveness ratio (ICER) of treatment was I$ 9,103/QALY for children and I$ 11,883/QALY for adolescents. In two-way sensitivity analysis, considering one Gross National Product per capita (I$ 11,530) as willingness-to-pay, a cost of no-treatment lower than I$ 45/month would render MPH-IR a cost-saving strategy. Discussion: MPH-IR treatment of children and adolescents is cost-effective for ADHD patients from the Brazilian public health system perspective. Both patients and the healthcare system might benefit from such a strategy. Trial registration number: NCT01705613.

Socio-demographic and clinical characteristics of pregnant and puerperal crack-cocaine using women: preliminary data

BACKGROUND The literature provides several studies on the effects of cocaine when exposed to the fetus. However, the majority of these data comes from animal models. OBJECTIVE The objective of this study is to present socio-demographic and clinical data in crack-cocaine using pregnant women and their babies, as compared to non-users. METHODS Cross-sectional study, comprised by 56 dyads of crack-cocaine using mothers-babies and 89 control dyads. In addition to the socio-demographic data and the babies’ information, data collection was based on ABIPEMI for socioeconomic level, WAIS for IQ, MINI for psychopathology and ASSIST for drug use. RESULTS Most crack users, in comparison to non-users, did not have a partner (10.52% vs 4.4%, P = 0.001) and presented lower IQ (78.15, +/-8.07 vs 84.27 +/- 9.87; P = 0.002). The prevalence of antisocial personality disorder and suicide risk in users was higher than in non-users (24.44% vs none, P < 0.001; 28.26% vs 10.46% P = 0.01). Most of the users did not participate in prenatal care (75%). The babies that the crack-cocaine using mothers gave birth to weighed significantly less than the controls (2.858 g vs 3.240 g, P = 0.002). DISCUSSION Users had a higher degree of psychopathology and lower attendance in prenatal care. There was an overlap of adverse factors, both for exposed mothers and babies. The sum of these vulnerabilities could result in significant harm to the developing infant. .

Tratamento psicoterápico para adolescentes usuários de substâncias psicoativas / Psychotherapeutic treatment for adolescents with substance abuse

O uso de álcool e demais substâncias psicoativas é um dos problemas de maior prevalência entre adolescentes. Todo adolescente que for avaliado por profissional de saúde deve ser questionado sobre seu uso de álcool e substâncias psicoativas. Em caso positivo, esse uso deve ser investigado clinicamente e, mesmo quando minimamente problemático, o adolescente deve ser encaminhado para tratamento específico. O tratamento deve levar em conta várias particularidades da adolescência para ser efetivo. Há indicação do uso de psicoterapias no atendimento a esses adolescentes. Entre elas, estão a Terapia de Família, a Terapia Cognitivo-Comportamental e a Entrevista Motivacional. Todas essas modalidades de terapia apresentam evidências de eficácia nessa faixa etária e podem ser usadas separadamente ou em conjunto. Essas modalidades de tratamento serão revisadas, sendo explicados seu método de ação e suas principais evidências de eficácia em adolescentes.(AU)

The use of alcohol and drugs in the adolescence is a common problem. Every teenager that goes through psychological evaluation should be asked about use of alcohol and drugs of abuse. If positive, this use should be clinically investigated and, referred to treatment at the slightest signs of problems. Treatment must take account of age-specific characteristics in order to be effective. There are many kinds of psychotherapies based on evidence for this age group. Among them, are Family Therapy, Cognitive Behavioral Therapy and Motivational Interviewing. Those treatment modalities are addressed, explaining their means of action and their main proofs of efficacy in adolescents.(AU)

Interrater agreement for the schedule for affective disorders and schizophrenia epidemiological version for school-age children (K-SADS-E)

OBJETIVE: The main objective of this study was to assess the interrater agreement for the Schedule for Affective Disorders and Schizophrenia Epidemiological version for School-Age Children (K-SADS-E). METHODS: Four interviewers being trained with the K-SADS-E scored independently 29 videotaped interviews performed with psychiatric outpatients in the ADHD Outpatient Clinic at Hospital de Clínicas de Porto Alegre. Interrater agreement analysis was performed using the kappa coefficient (k). RESULTS: Kappa coefficients were .93 (p<.001) for affective disorders, .9 (p<.001) for anxiety disorders, .94 (p<.001) for attention-deficit/hyperactivity disorders and disruptive behavior disorders. CONCLUSION: These findings suggest an excellent interrater agreement for the diagnosis of several mental disorders in childhood and adolescence by the Brazilian Portuguese version of the K-SADS-E
