Objetivo: Realizar uma revisão sistemática da literatura científica sobre o uso de antipsicóticos atípicos (APAs) no tratamento da agressividade patológica em crianças e adolescentes. Método: Foi realizada busca eletrônica nas bases de dados MEDLINE, SciELO e LILACS, de 1992 a agosto 2011, considerando artigos publicados em língua inglesa e portuguesa. Foram utilizadas associações das seguintes expressões: mental disease, child, adolescent, treatment, atypical antipsychotic, aggressive behaviour, aggression e violent behavior. Resultados: Foram identificados 67 artigos de boa qualidade metodológica, de relevância e interesse clínico para o tema em foco. De modo geral, os estudos são relativamente limitados para esta faixa etária, resultado do fato de poucos APAs terem sido aprovados pela Food and Drug Administration (FDA). Dentre as medicações consideradas nesta revisão (risperidona, olanzapina, quetiapina, ziprazidona, aripiprazol e clozapina), todas elas podem ter alguma efetividade no tratamento da agressividade em crianças e adolescentes, ficando a escolha baseada na indicação clínica e perfil de efeitos colaterais. Conclusão: O número ainda limitado de estudos acerca da efetividade e segurança na população pediátrica demanda pesquisas futuras com grupos maiores de pacientes e com mais categorias diagnósticas (como, por exemplo, as formas graves de transtorno de conduta e transtorno desafiador de oposição), desenhadas de forma randomizada e controlada. Assim poderão ser confirmados os achados até o momento e o impacto do uso em longo prazo.

Objective: To review the literature about the use of atypical antipsychotics in the treatment of pathological aggression in children and adolescents. Method: The databases MEDLINE, SciELO, and LILACS were searched for publications in Portuguese or English from 1992 to August 2011 using the following keywords: mental disease, child, adolescent, treatment, atypical antipsychotic, aggressive behavior, aggression, and violent behavior. Results: Sixty-seven studies of good methodological quality and clinical interest and relevance were identified. Studies including children and adolescents were relatively limited, because few atypical antipsychotics have been approved by the Food and Drug Administration (FDA). All the medications included in this review (risperidone, olanzapine, quetiapine, ziprasidone, aripiprazole and clozapine) have some effectiveness in treating aggression in children and adolescents, and choices should be based on clinical indications and side effects. Conclusions: There are few studies about the effectiveness and safety of atypical antipsychotics for the pediatric population, and further randomized controlled studies with larger groups of patients and more diagnostic categories, such as severe conduct disorder and oppositional defiant disorder, should be conducted to confirm the results reported up to date and to evaluate the impact of long-term use.

OBJETIVO: Estudar crianças e adolescentes vítimas de violência doméstica da Unidade de Emergência Referenciada Pediátrica (UERP) do Hospital das Clínicas (HC) - Universidade Estadual de Campinas (UNICAMP) e ambulatório especializado, entre janeiro de 2003 e dezembro de 2007, enfatizando o abuso sexual. MÉTODOS: Analisou-se: gênero, idade, procedência e classificação. Para as vítimas de abuso sexual estudou-se: tipo de abuso (estupro), local (doméstico/urbano), duração (aguda/crônica), autor (conhecido; incestuoso), alterações no exame médico, notificação ao conselho tutelar, medicação antirretroviral e sorologias (HIV, Lues, hepatite B e C). Dividiu-se em dois grupos com relação ao tipo de abuso e ao autor e associou-se a gênero, idade e duração. Para a comparação calculou-se o Qui-quadrado ou Exato de Fisher (significância p < 0,05) e a razão de chance prevalente bruta. RESULTADOS: Do total (551), predominou a negligência (33,9%) e abuso sexual (31,9%), sendo 55,9% nas meninas e 50% até 5 anos. Do abuso sexual (95), 80% eram meninas e 58,9% entre 5-10 anos. Observou-se estupro entre 39% e atentado ao pudor em 59,6%; 72,6% foram em área doméstica, 81,1% por autor conhecido, 31,6% por relação incestuosa, 47,4% crônica e 76,5% sem alteração clínicas, sendo 81,1% encaminhados ao conselho tutelar. Medicação antirretroviral foi indicada para 49,1% dos pacientes, e sorologias: HIV em 46 (48,4%), Lues em 42 (44,2%), hepatite B em 44 (46,3%) e hepatite C em 45 (47,4%), todas negativas, mais frequente nas vítimas de estupro (p = 0,00). Ocorreu associação entre estupro e idade (10 e 15 anos p = 0,01) e autor incestuoso e duração crônica (p = 0,01). CONCLUSÃO: Apesar de não refletir a realidade, serve como alerta aos pediatras.

OBJECTIVE: To study children and adolescents victims of domestic violence treated at the Referenced Pediatric Emergency Unit of the Hospital de Clínicas of the Universidade Estadual de Campinas and its specialized outpatient clinic between January 2003 and December 2007, emphasizing sexual abuse. METHODS: The variables gender, age, origin, and classification were studied. For victims of sexual abuse, the following variables were also studied: type of abuse (rape), location (domestic/urban), duration (acute/chronic), perpetrator (known, incestuous), alterations at medical examination, notification to child protection agencies, and antiretroviral medication and serology (HIV, syphilis, hepatitis B and C). Patients were divided into two groups according to the type of abuse and type of perpertrator and they were associated with gender, age, and duration. For the comparison, chi-squared or Fisher's exact test were performed (significance p < 0.05), as well as raw prevalence odds ratio. RESULTS: Of the total cases of abuse (551), neglect (33.9%) and sexual abuse (31.9%) predominated; the victims were female in 55.9% of the cases, and 50% were up to 5 years of age. Of the sexual abuse cases (95), 80% were female, and 58.9% were between 5 and 10 years of age. Rape was observed in 39% and indecent assault in 59.6%; 72.6% occurred in the domestic area, 81.1% by known perpetrator; 31.6% were incestuous, 47.4% were chronic, and 76.5% had no clinical alterations. 81.1% were referred to child protection agencies. Antiretroviral medication was prescribed to 49.1% of patients, and serological tests (HIV in 46 [48.4%], syphilis in 42 [44.2%], hepatitis B in 44 [46.3%] and hepatitis C in 45 [47.4%]%), all of which were negative, were more frequent in rape victims (p = 0.00). There was an association between rape and age (10 and 15 years, p = 0.01) and between incestuous perpetrator and chronic duration (p = 0.01). CONCLUSION: Although this study does not reflect reality, it can be used as a warning to pediatricians.

Os autores traduzem, pela primeira vez para o português, o artigo de Charles Darwin "A Biographical Sketch of an Infant", publicado no periódico Mind em julho de 1877. Utilizando anotações de observações do desenvolvimento de seus filhos, especialmente de seu filho mais velho William Erasmus (Doddy), Darwin descreve e estuda, a partir de seu enfoque naturalista, o filhote humano, narrando os primeiros indicativos comportamentais de emoções tais como raiva e medo, curiosidade e senso moral, o brincar e o prazer envolvido nesta atividade, a capacidade de imitação e os primeiros indícios daquilo que hoje conhecemos como "teoria da mente". Colocando-se questões sobre as capacidades do bebê, como eles aprendem e como se comunicam e levantando hipóteses sobre possíveis significados de certos comportamentos, questões ainda hoje fundamentais para o estudo do desenvolvimento humano, Darwin mostra-se também um pioneiro no estudo do bebê e da criança pequena, numa época na qual as capacidades dos bebês eram extremamente subestimadas e desconsideradas.

The authors provide the first translation into Portuguese of Charles Darwin's article "A Biographical Sketch of an Infant," published in the journal Mind in July of 1877. Using notes from observations of the development of his children, especially his oldest son William Erasmus (Doddy), Darwin uses his naturalistic approach to describe and study "human puppies," providing the first behavioral indicators of emotions such as anger and fear, curiosity and moral sense. He also notes the play and pleasure involved in these activities, along with the ability to imitate and the earliest indicators of what we refer to today as "theory of the mind." Darwin raises questions about the capabilities of babies, how they learn and how they communicate and generate hypotheses about possible meanings of certain behaviors. These issues are still critical to the study of human development. This shows that he was also a pioneer in the study of babies and young children at a time when the capacity of babies was underestimated and ignored.

Les auteurs ont effectués la traduction inédite en portugais de l'article de Charles Darwin, "A Biographical Sketch of an Infant" publié dans la revue Mind en Juillet 1877. En utilisant les notes d'observations sur le développement de ses enfants, notamment de son fils aîné, William Erasmus (Doddy), Darwin étudie et décrit l'enfant humain de son point-de-vue naturaliste. Il décrit ainsi les premiers indicateurs du comportement sentimental, comme la colère et la peur, la curiosité et le sens moral, le jeu et le plaisir qu'implique cette activité, la capacité d'imiter et le début de ce que nous appelons aujourd'hui la "théorie de l'esprit". Dans cet article, Darwin pose des questions sur les capacités de l'enfant, leur façon d'apprendre et de communiquer. Il crée des hypothèses sur les possibles significations de certains comportements, questions qui sont encore aujourd'hui critiques à l'étude du développement humain et qui montrent que Darwin fut également un pionnier des études sur les bébés et les petits enfants à une époque où la capacité des bébés était gravement sous-estimée et négligée.

This paper presents an automatic procedure employing a reagent in the form of a slurry in a flow-injection system. The feasibility of the proposal is demonstrated by sulphate determination in water using the Barium Chloranilate method, which is based on the precipitation of barium sulphate. The release of a stoichiometric amount of highly colored chloranilic ions is monitored at 528 nm. The reaction is carried out in alcoholic medium in order to reduce the solubility of the reagent. A considerable improvement in the sensitivity is attained by adding ferric ions to the released chloranilic ions. An on-line filtration step to separate the excess reagent from the released chloranilic ions was necessary. In addition, a column containing a cation exchange resin was included in the manifold to remove potentially interfering ions. The proposed procedure is suitable for 30 determinations per hour and the relative standard deviation is less than 2%. The analytical curve is linear between 0.0 and 40 mg L-1 and the determination limit is about 2.0 mg L-1SO4(2-). Accuracy was confirmed by running several samples already analysed by a standard turbidimetric procedure.

This paper presents a system for electrochemical hydride generation using flow-injection and atomic absorption spectrometry to determine selenium in biological materials. The electrolytic cell was constructed by assembling two reservoirs, one for the sample and the other for the electrolytic solution separated by a Nafion membrane. Each compartment had a Pt electrode. The sample and electrolyte flow-rates, acidic media, and applied current were adjusted to attain the best analytical performance and ensure the membrane lifetime. The atomisation system used a T quartz tube in an air-LPG flame. The composition of the flame, the observation height, and the argon flow rate used to carry the hydrides were critically investigated. The system allowed to perform thirty determinations per hour with a detection limit of 10 mug L-1 of Se. Relative standard deviations were in general lower than 1.5% for a solution containing 20.0 and 34.0 mug L-1 of Se in a typical sample digest. Accuracy was assessed analysing the certified materials: rice flour (NIST-1568) from National Institute of Standard and Technology and dried fish (MA-A-2), whole animal blood (A-2/1974) from the International Atomic Energy Agency.
