Decoding the Prevalent High-Risk Breast Cancers: Demographics, Pathological, Imaging Insights, and Long-Term Outcome.

Objective: To investigate the features and outcomes of breast cancer in high-risk subgroups. Materials and Methods: REB approved an observational study of women diagnosed with breast cancer from 2010 to 2019. Three radiologists, using the BI-RADS lexicon, blindly reviewed mammogram and MRI screenings without a washout period. Consensus was reached with 2 additional reviewers. Inter-rater agreement was measured by Fleiss Kappa. Statistical analysis included Mann-Whitney U, Chi-square tests for cohort analysis, and Kaplan-Meier for survival rates, with a Cox model for comparative analysis using gene mutation as a reference. Results: The study included 140 high-risk women, finding 155 malignant lesions. Significant age differences noted: chest radiation therapy (median age 44, IQR: 37.0-46.2), gene mutation (median age 49, IQR: 39.8-58.0), and familial risk (median age 51, IQR: 44.5-56.0) (P = .007). Gene mutation carriers had smaller (P = .01), higher-grade tumours (P = .002), and more triple-negative ER- (P = .02), PR- (P = .002), and HER2- (P = .02) cases. MRI outperformed mammography in all subgroups. Substantial to near-perfect inter-rater agreement observed. Over 10 years, no deaths occurred in chest radiation group, with no significant survival difference between gene mutation and familial risk groups, HR = 0.93 (95% CI: 0.27, 3.26), P = .92. Conclusion: The study highlights the importance of age and specific tumour characteristics in identifying high-risk breast cancer subgroups. MRI is confirmed as an effective screening tool. Despite the aggressive nature of cancers in gene mutation carriers, early detection is crucial for survival outcomes. These insights, while necessitating further validation with larger studies, advocate for a move toward personalized medical care, strengthening the existing healthcare guidelines.

Effects of delayed callback from screening mammography due to the COVID-19 pandemic.

OBJECTIVE: To determine the frequency and distinguishing imaging characteristics of breast cancers detected on screening mammography which was initially evaluated as a probably benign lesion and the workup was delayed due to the COVID-19 pandemic. MATERIALS AND METHODS: REB-approved multicenter retrospective screening mammography studies and patient's chart review carried out between February 2020 and March 2020. According to an institutional decision, the frequency and imaging findings deemed probably benign on screening mammography after review by a breast fellowship-trained radiologist with workup deferred until after the first pandemic wave plateau in late July 2020 were recorded. Results were correlated with histopathology if tissue sample performed or an uneventful 2 years follow-up. Descriptive statistical analysis was used to describe the retrieved data set. RESULTS: Out of 1816 mammography screening between February 2020 and March 2020, 99 women, median age 58 years (range 35-84), 99 mammography had possibly benign findings with workup delayed, and two patients, age 49 and 56, had cancers (2.02%), misinterpreted as benign findings. Both malignant cases were focal asymmetries, with pathology of invasive ductal carcinoma, 12 mm and 9 mm in size. No in-situ carcinoma was detected. CONCLUSION: The low rate of cancer detected suggests that a delay callback may be a reasonable option for some likely benign findings when immediate callback is not an option, such as during a pandemic. Larger studies would be helpful to support our findings and may allow us to translate the adoption of such a model during potential future pandemic. CLINICAL RELEVANCE: The results of this study may be helpful for a future situation when delaying a call back from screening mammography is again required.

What does immunology have to do with brain development and neuropsychiatric disorders?

Introduction: Neural development is an enormously complex and dynamic process. From very early in brain development 'immune cells' play a key role in a number of processes including the formation and refinement of neural circuits, as well as sexual differentiation. There is a growing body of evidence that the immune system also plays an important role in the pathobiology of several neurodevelopmental and neuropsychiatric disorders. Objective: The goal of this article is to review the currently available data concerning the role of the 'immune system' in normal brain development, as well as its role in the pathobiology of neurodevelopmental and neuropsychiatric disorders. Methodology: We conducted a traditional literature search using PubMed and recent special issues of journals to locate relevant review articles. Results: The cellular and molecular processes that make up our 'immune system' are crucial to normal brain development and the formation and maintenance of neural circuits. It is also increasingly evident that the immune system and neuroinflammation play important roles in the pathobiology of at least a subset of individuals with Autism Spectrum Disorder (ASD), schizophrenia, obsessive-compulsive disorder, Tourette syndrome and mood disorders, such as depression, as well as autoimmune and neurodegenerative disorders. Emerging evidence also points to the importance of the 'gut-brain axis' and an individual's microbiome, which can impact an individual's somatic and mental well-being. Conclusions: There are multidirectional interconnections across multiple biological systems in our brains and bodies that are mediated in part by the immune system. At present, however, the 'promise' of this field remains greater than the 'deliverables'. Time will tell whether novel interventions will be developed that will make a positive difference in the care of our patients. It is also possible that valid biomarkers will emerge that will guide a more personalized approach to treatment.

Introdução: O desenvolvimento neural é um processo extremamente complexo e dinâmico. Tao pronto se inicia o desenvolvimento do cérebro, as "células imunológicas" desempenham um papel fundamental em vários processos, incluindo a formação e aperfeiçoamento de circuitos neurais, bem como a diferenciação sexual. Há um crescente corpo de evidências de que o sistema imunológico também desempenha um papel importante na fisiopatologia de diversos transtornos neurodesenvolvimentais e neuropsiquiátricos. Objetivo: O objetivo deste artigo é revisar os dados atualmente disponíveis sobre o papel do "sistema imunológico" em relação ao desenvolvimento normal do cérebro, bem como a fisiopatogenia dos transtornos de neurodesenvolvimento e neuropsiquiátricos. Metodologia: Foi realizada uma pesquisa bibliográfica tradicional para localizar artigos de revisão relevantes. Resultados: Os processos celulares e moleculares que compõem o nosso "sistema imunológico" são cruciais para o desenvolvimento normal do cérebro e a formação e manutenção de circuitos neurais. É cada vez mais evidente que o sistema imunológico e neuroinflamação desempenham papéis importantes na etiopatogenia de pelo menos um subconjunto de indivíduos com autismo, esquizofrenia, transtorno obsessivo-compulsivo, síndrome de Tourette, depressão e transtornos do humor, bem como distúrbios autoimunes e neurodegenerativos. Evidências emergentes também apontam para a importância do eixo intestino-cerebral e do microbioma de um indivíduo em relação à sua saúde e bem-estar somático e mental. Conclusões: Existem interconexões multidirecionais entre múltiplos sistemas biológicos em nossos cérebros e corpos que são mediados em parte pelo sistema imunológico. No momento, no entanto, a "promessa" desse campo continua sendo maior do que os "resultados finais". O tempo dirá se novas intervenções serão desenvolvidas que farão uma diferença positiva no cuidado de nossos pacientes. Também é possível que surjam biomarcadores válidos que orientarão uma abordagem mais personalizada ao tratamento.

Assessment of Safety and Outcome of Lateral Hypothalamic Deep Brain Stimulation for Obesity in a Small Series of Patients With Prader-Willi Syndrome.

Importance: Deep brain stimulation (DBS) has been investigated for treatment of morbid obesity with variable results. Patients with Prader-Willi syndrome (PWS) present with obesity that is often difficult to treat. Objective: To test the safety and study the outcome of DBS in patients with PWS. Design, Setting, and Participants: This case series was conducted in the Hospital das Clínicas, University of São Paulo, Brazil. Four patients with genetically confirmed PWS presenting with severe obesity were included. Exposure: Deep brain stimulation electrodes were bilaterally implanted in the lateral hypothalamic area. After DBS implantation, the treatment included the following phases: titration (1-2 months), stimulation off (2 months), low-frequency DBS (40 Hz; 1 month), washout (15 days), high-frequency DBS (130 Hz; 1 month), and long-term follow-up (6 months). Main Outcomes and Measures: Primary outcome measures were adverse events recorded during stimulation and long-term DBS treatment. Secondary outcomes consisted of changes in anthropometric measures (weight, body mass index [calculated as weight in kilograms divided by height in meters squared], and abdominal and neck circumference), bioimpedanciometry, and calorimetry after 6 months of treatment compared with baseline. The following evaluations and measurements were conducted before and after DBS: clinical, neurological, psychiatric, neuropsychological, anthropometry, calorimetry, blood workup, hormonal levels, and sleep studies. Adverse effects were monitored during all follow-up visits. Results: Four patients with PWS were included (2 male and 2 female; ages 18-28 years). Baseline mean (SD) body mass index was 39.6 (11.1). Two patients had previous bariatric surgery, and all presented with psychiatric comorbidity, which was well controlled with the use of medications. At 6 months after long-term DBS, patients had a mean 9.6% increase in weight, 5.8% increase in body mass index, 8.4% increase in abdominal circumference, 4.2% increase in neck circumference, 5.3% increase in the percentage of body fat, and 0% change in calorimetry compared with baseline. Also unchanged were hormonal levels and results of blood workup, sleep studies, and neuropsychological evaluations. Two patients developed stimulation-induced manic symptoms. Discontinuation of DBS controlled this symptom in 1 patient. The other required adjustments in medication dosage. Two infections were documented, 1 associated with skin picking. Conclusions and Relevance: Safety of lateral hypothalamic area stimulation was in the range of that demonstrated in patients with similar psychiatric conditions receiving DBS. In the small cohort of patients with PWS treated in our study, DBS was largely ineffective.

DBS for Obesity.

Obesity is a chronic, progressive and prevalent disorder. Morbid obesity, in particular, is associated with numerous comorbidities and early mortality. In patients with morbid obesity, pharmacological and behavioral approaches often have limited results. Bariatric surgery is quite effective but is associated with operative failures and a non-negligible incidence of side effects. In the last decades, deep brain stimulation (DBS) has been investigated as a neurosurgical modality to treat various neuropsychiatric disorders. In this article we review the rationale for selecting different brain targets, surgical results and future perspectives for the use of DBS in medically refractory obesity.

N-Acetylcysteine in the Treatment of Pediatric Tourette Syndrome: Randomized, Double-Blind, Placebo-Controlled Add-On Trial.

BACKGROUND: Current pharmacological treatments for Tourette Syndrome (TS), such as antipsychotic agents and α-2 agonists, are moderately effective in the treatment of tics, but have substantial side effects that limit their use. N-acetylcysteine (NAC) modulates glutamatergic systems, and has been used safely as an antioxidant agent with minimal side effects for decades. NAC has been increasingly studied for the treatment of other obsessive-compulsive spectrum disorders. We aim to examine the efficacy of NAC for the treatment of pediatric TS in a double-blind, placebo-controlled, add-on study. METHODS: Thirty-one children and adolescents 8-17 years of age with TS were randomly assigned to receive NAC or matching placebo for 12 weeks. Our primary outcome was change in severity of tics as measured by the Yale Global Tic Severity Scale (YGTSS), Total tic score. Secondary measures assessed comorbid obsessive-compulsive disorder (OCD), depression, anxiety, and attention-deficit/hyperactivity disorder (ADHD). Linear mixed models in SAS were used to examine differences between NAC and placebo. RESULTS: Of 31 randomized subjects, 14 were assigned to placebo (two females; 11.5 + 2.8 years) and 17 to active NAC (five females; 12.4 + 1.4 years) treatment. No significant difference between NAC and placebo was found in reducing tic severity or any secondary outcomes. CONCLUSIONS: We found no evidence for efficacy of NAC in treating tic symptoms. Our findings stand in contrast to studies suggesting benefits of NAC in the treatment of other obsessive-compulsive spectrum disorders in adults, including OCD and trichotillomania, but are similar to a recent placebo-controlled trial of pediatric trichotillomania that found no benefit of NAC.

High risk cohort study for psychiatric disorders in childhood: rationale, design, methods and preliminary results.

The objective of this study is to present the rationale, methods, design and preliminary results from the High Risk Cohort Study for the Development of Childhood Psychiatric Disorders. We describe the sample selection and the components of each phases of the study, its instruments, tasks and procedures. Preliminary results are limited to the baseline phase and encompass: (i) the efficacy of the oversampling procedure used to increase the frequency of both child and family psychopathology; (ii) interrater reliability and (iii) the role of differential participation rate. A total of 9937 children from 57 schools participated in the screening procedures. From those 2512 (random = 958; high risk = 1554) were further evaluated with diagnostic instruments. The prevalence of any child mental disorder in the random strata and high-risk strata was 19.9% and 29.7%. The oversampling procedure was successful in selecting a sample with higher family rates of any mental disorders according to diagnostic instruments. Interrater reliability (kappa) for the main diagnostic instrument range from 0.72 (hyperkinetic disorders) to 0.84 (emotional disorders). The screening instrument was successful in selecting a sub-sample with "high risk" for developing mental disorders. This study may help advance the field of child psychiatry and ultimately provide useful clinical information.

Sintomas obsessivo-compulsivos em escolares: prevalência, dimensões psicopatológicas, agregação familiar, comorbidades e fatores clínicos associados / Obsessive-compulsive symptoms in schoolchildren: prevalence, dimensions, familial aggregation, comorbidities and associated clinical factors

O objetivo central desta tese de doutorado foi investigar as características clínicas de sintomas obsessivo-compulsivos (SOC), como fenômeno intermediário entre o desenvolvimento normal e o transtorno obsessivo-compulsivo (TOC), em uma ampla amostra comunitária (não-clínica) composta por crianças em idade escolar (6 a 12 anos) e seus familiares biológicos. Para tal, determinou-se a prevalência e a distribuição sociodemográfica dos SOC descrevendo sua fenomenologia caracterizada a partir de dimensões de SOC, agregação familiar, associação com outras comorbidades psiquiátricas e outras variáveis de comprometimento clínico (ex: fatores de risco, problemas sociais, escolares e de comportamento). Dividimos o presente estudo em duas etapas. Na Etapa I, o objeto de estudo foram 9.937 crianças de 6 a 12 anos regularmente matriculadas em escolas públicas (crianças-index) e seus familiares biológicos (n total=29.459). Nesta etapa utilizou-se a Family History Screening (FHS), escala de rastreamento para sintomas psiquiátricos internacionalmente validada, e um módulo adicional com sete itens para identificar quatro dimensões de SOC ("Agressão/ sexual/ religiosa"; "arranjo/ simetria"; "contaminação/ lavagem" e colecionismo"). Nessa primeira etapa obtivemos dados sobre 9.937 crianças-index (podendo ser irmãos entre si), 3.305 irmãos biológicos (13 a 18 anos) e 16.218 pais. As mães biológicas foram informantes em 88% das entrevistas. Os SOC estiveram presentes em 19.4% da amostra total, sendo 14,7% das crianças-index; 15,6% dos irmãos; 34,6% das mães e 12,1% dos pais. A presença dos SOC foi associada ao sexo masculino e aumento da idade em crianças e adolescentes. Houve agregação familiar das dimensões de SOC nas famílias, sendo que a dimensão de "contaminação/ lavagem" foi a mais familiar (OR: 1,44; IC 95% 1,23-1,67; p < 0,001). Crianças-index com SOC apresentaram maior frequência de outros sintomas psiquiátricos, bem como maior comprometimento escolar...

The present thesis investigated the clinical characteristics of obsessive-compulsive symptoms (OCS), as an intermediate phenomenon between normal development and obsessive-compulsive disorder (OCD) by assessing an extensive community (non- clinical) sample of schoolchildren (6-12 years) and their biological relatives. We determined the prevalence and sociodemographic status of OCS, describing its phenomenology characterized from OCS dimensions, familial aggregation, association with other psychiatric comorbidities, and other variables of clinical impairment (e.g.: risk factors , social, school and behavior problems). The study was divided in two phases. In phase I, 9,937 children (aged 6 to 12 years) enrolled in regular public schools (index-children) and their biological relatives (overall n = 29,459) were assessed. In this phase, we used the Family History Screening (FHS), an internationally validated instrument developed for psychiatric symptoms assessment. An additional seven-item module to identify four OCS dimensions ("aggressive/ sexual/ religious"; "symmetry/ arranging", "contamination/ cleaning" and "hoarding ") was also used. In the first phase data on 9,937 index-children (may be siblings to each other), 3,305 biological siblings (13-18 years) and 16,218 parents were obtained. The biological mothers were informants in 88 % of the interviews. OCS were present in 19.4 % of the total sample, 14.7 % of index-children, 15.6 % of siblings, 34.6 % of mothers and 12.1 % of parents. The presence of OCS was associated with male gender and increasing age in children and adolescents. Familial aggregation of OCS dimensions was found; the "contamination/ cleaning" was the most familial dimension (OR: 1.44; 95% IC 1.23 to 1.67; p < 0.001). OCS were associated with higher frequency of other psychiatric symptoms as well as greater rates of social/ school problems and searching for previous treatments. The main limitations of this phase include by proxy interviews...

Gender differences in obsessive-compulsive disorder: a literature review / Diferenças de gênero no transtorno obsessivo-compulsivo: uma revisão da literatura

INTRODUCTION: Obsessive-compulsive disorder (OCD) is a heterogeneous condition, in which subtypes have been proposed. Previous studies suggested that gender plays a relevant role in OCD phenotypic expression. This study aimed to review the literature on gender differences in clinical, genetic or familial aspects of OCD. METHOD: A conventional review was conducted, including all papers that investigated demographic, clinical, and genetic aspects of OCD according to gender. The search was based on data available in Medline and PsycINFO databases in the last 20 years, using as keywords: obsessive-compulsive disorder; and: gender, sex, male, female, demographic characteristics, clinical features, clinical characteristics, genetic, genes, genetics gender OCD, genes OCD, genes OCD males, genes OCD females. RESULTS: Sixty three of 487 phenotypical and genetics studies were selected. Most studies indicate that male patients are more likely than females to be single, present early onset of symptoms and chronic course of the disorder, greater social impairment, more sexual-religious and aggressive symptoms, and greater comorbidity with tic and substance use disorders. Female patients present more contamination/cleaning symptoms and greater comorbidity with eating and impulse-control disorders. Genetic and family studies are inconclusive, but suggest that gender may play a role in the disease expression. CONCLUSIONS: Gender is a relevant factor that should be taken into account when evaluating OCD patients. More studies are necessary to determine whether in fact it defines a homogeneous and particular group in OCD.

INTRODUÇÃO: O transtorno obsessivo-compulsivo (TOC) é um quadro heterogêneo, no qual subtipos têm sido propostos. Estudos anteriores sugerem que gênero desempenha papel relevante na expressão fenotípica. O objetivo foi realizar uma revisão convencional da literatura sobre diferenças de gênero em relação a aspectos clínicos e genéticos ou familiares do TOC. MÉTODO: Realizou-se uma revisão convencional da literatura incluindo todos os artigos que investigaram aspectos sociodemográficos, clínicos e genéticos do TOC, de acordo com o gênero. A pesquisa foi baseada em publicações disponíveis nas bases de dados Medline e PsycInfo nos últimos 20 anos, usando como palavras-chave: obsessive-compulsive disorder (OCD), e: gender, sex, male, female, demographic characteristics, clinical features, clinical characteristics, genetic, genes, genetics gender OCD, genes OCD, genes OCD males, genes OCD females. RESULTADO: Sessenta e três artigos de fenótipo e genética foram selecionados. Na maioria dos estudos, o sexo masculino associou-se mais que o feminino com: ser solteiro, apresentar início mais precoce dos sintomas, maior prejuízo social, mais sintomas sexuais, religiosos e de agressão, e mais comorbidade com transtorno de tiques e abuso de substâncias. Pacientes do sexo feminino apresentam mais sintomas de contaminação/limpeza e mais comorbidade com transtornos alimentares e do controle de impulsos. Estudos genéticos e familiares são controversos, mas indicam que o gênero pode desempenhar um papel na expressão da doença. CONCLUSÃO: Gênero é um fator relevante a ser considerado na avaliação de pacientes com TOC. São necessários mais estudos para determinar se este fator define de fato um grupo homogêneo e particular de TOC.

Instruction in developmental psychiatry: preliminary findings at the undergraduate level in Brazil / Educação em psiquiatria do desenvolvimento: resultados preliminares em estudantes de graduação no Brasil

BACKGROUND: Although knowledge on developmental psychiatry is fundamental for the early recognition, treatment, and prevention of mental disorders, this subject has not been incorporated into the medical curriculum or psychiatric practice in Brazil. OBJECTIVE: To evaluate the effect of a short course on developmental psychiatry for undergraduate students and to expand education policies concerning developmental psychiatry in Brazil. METHODS: Before and after attending an extracurricular 12-hour, 4-day course on the fundamentals of developmental psychiatry, undergraduate health sciences students were tested regarding their knowledge of the subject. The pre-test/post-test included 12 randomly selected multiple-choice questions designed to evaluate knowledge related to developmental psychiatry and was administered together with a questionnaire designed to evaluate students' attitudes. To compare performances between groups, nonparametric analyses of ordinal categorical data were employed. RESULTS: The final sample comprised 43 students. The mean post-test score was significantly higher than the mean pre-test score (65.0 percent vs 39.9 percent; p < 0.0001). We found that strongly positive attitudes correlated with better performance. The 3rd and 4th year medical students performed better than the 1st and 2nd year medical students and the non-medical students. Sex differences favoring males were also observed. CONCLUSION: Our findings encourage additional educational policies related to developmental psychiatry which may result in direct clinical implications.

CONTEXTO: Apesar de vital para o reconhecimento precoce, tratamento e prevenção de transtornos mentais, a psiquiatria do desenvolvimento ainda não foi incorporada à grade curricular ou prática psiquiátrica no Brasil. OBJETIVO: Avaliar o impacto de um curso extracurricular em psiquiatria do desenvolvimento na graduação e a viabilidade de expansão de políticas de ensino em psiquiatria do desenvolvimento no Brasil. MÉTODO: Antes e após assistirem um curso de 12 horas durante 4 dias sobre fundamentos da psiquiatria do desenvolvimento, estudantes de graduação em saúde responderam um questionário composto por 12 questões de múltipla escolha randomizadas para avaliação de retenção do conhecimento e questões destinadas à avaliação de atitudes. A análise estatística incluiu testes não-paramétricos de variáveis categóricas ordinais. RESULTADOS: Em uma amostra final composta por 43 estudantes, verificou-se um desempenho significativamente superior no pós-teste (65.0 por cento vs. 39.9 por cento; p < 0.0001). Atitudes positivas em relação ao curso relacionaram-se a um melhor desempenho. Estudantes dos 3º e 4º anos de medicina apresentaram resultados superiores quando comparados aos do 1º e 2º anos de medicina e aos estudantes de outras áreas da saúde. Constatou-se melhor desempenho no sexo masculino. CONCLUSÃO: Este estudo encoraja políticas de ensino em psiquiatria do desenvolvimento que poderão ter implicações clínicas diretas.

Custos dos problemas causados pelo abuso do álcool / The cost of problems caused by alcohol abuse

CONTEXTO: O abuso de álcool é considerado atualmente um dos maiores problemas de saúde devido ao impacto mundial que esta problemática gera em termos sociais e financeiros. OBJETIVOS: Discutir, a partir do referencial econômico, as conseqüências sociais do abuso do álcool e introduzir os conceitos relacionados à economia da saúde. MÉTODOS: Revisão da literatura com base nos sistemas Medline, LILACS e Scielo de artigos publicados nas línguas, portuguesa e inglesa no período de 1987 a 2007, e posterior busca manual com base na bibliografia de interesse dos artigos selecionados. RESULTADOS: Foram encontrados 50 artigos sobre estudos econômicos e conceitos econômicos em diversas áreas; desses, 15 diretamente relacionados ao custo social do abuso do álcool. O método de apuração dos custos e a composição dos itens de custos foram semelhantes em todos os estudos. CONCLUSÕES: Os estudos econômicos se apresentam incipientes no Brasil e avançados nos países desenvolvidos. A necessidade de pesquisas nacionais que abordem o custo social do abuso do álcool tem como uma das finalidades promover subsídios para se pensar e efetivar a construção de políticas públicas mais consistentes e que estejam em consonância com o perfil epidemiológico e socioeconômico do país.

BACKGROUND: Alcohol abuse is currently considered one of the largest worldwide health problems due to its social and financial impact. OBJECTIVES: To discuss the economic and social impact of alcohol abuse and to introduce concepts related to health economics. METHODS: Literature review of articles written in Portuguese and in English (published between 1987 and 2007) stored in the MEDLINE, LILACS and Scielo databases was carried out. RESULTS: Fifty articles on economic studies and economic concepts in various areas were found, among which 15 were directly related to the social costs of alcohol abuse. The costs assessment methods and the composition of cost items were similar in all studies. CONCLUSIONS: Economic studies are new in Brazil, but are advanced in developed countries. National research on the social costs of alcohol abuse is necessary in order to promote knowledge as a means of creating and implementing public policies that are more consistent with and in alignment with the epidemiological and socioeconomic profile of the country.

Jogos de azar e uso de substâncias em idosos: uma revisão da literatura / Gambling and substance use by the elderly: a review of the literature

CONTEXTO: A literatura mostra comorbidade entre jogo patológico, abuso de substâncias e transtornos afetivos (maior prevalência de depressão) em adultos. É alta a prevalência de depressão nos idosos, tornando-os vulneráveis à dependência de jogos de azar e ao abuso de substâncias. Com o aumento desta população em todo o mundo, faz-se necessário mais pesquisas sobre esse tema. OBJETIVOS: Avaliar o grau de envolvimento do idoso que aposta em jogos de azar e sua correlação com uso de substâncias. MÉTODOS: Revisão bibliográfica dos bancos de dados MEDLINE, LILACS e PsycINFO, sem limite de tempo. RESULTADOS: Idosos apostadores recreativos de jogos de azar apresentam consumo principalmente de álcool e boa avaliação de saúde geral. Idosos com problemas com jogo apresentam abuso de álcool, mais transtornos psiquiátricos e doenças cardiovasculares que os idosos jogadores recreativos. Quando comparados com adultos ou jovens jogadores, os idosos apresentam menos problemas relacionados ao consumo de álcool. CONCLUSÕES: Assim como nos adultos, também existe correlação entre apostas em jogos de azar e consumo de substâncias nos idosos. Quanto mais problemático o envolvimento com jogo, mais problemático é o consumo de substâncias (álcool) e maior prevalência de transtornos do humor (depressão). No entanto, não se pode afirmar uma relação causal entre esses fatores, sendo necessária realização de mais pesquisas sobre esse tema.

BACKGROUND: Literature presents comorbidity between pathological gambling, substance use/abuse and affective disorders (depression being the most prevalent) in adults. The prevalence of depression disorder in elderly people is high, making them vulnerable to pathological gambling and substance abuse. With the increase of this population worldwide, more research regarding these issues has become necessary. OBJECTIVES: Assess the involvement of the elderly in gambling activities and its correlation with substance abuse. METHODS: Literature review of MEDLINE, LILACS and PsycINFO databases without time limits. RESULTS: Elderly recreational gamblers present alcohol consumption and good general health. Elderly problem gamblers present alcohol abuse, with more psychiatric disorders and heart disease than recreational gamblers. When compared with adult or young gamblers, the elderly present fewer problems with alcohol consumption. Conclusions: As with adults, in the elderly a correlation also exists between gambling and substance abuse. The more problematic the gambling is, the more problematic the substance (alcohol) abuse, and the higher the prevalence of mood disorders (depression). A causal relationship between these factors can not yet be affirmed however, as more research is needed.

Uso de olanzapina e eletroconvulsoterapia em um paciente com esquizofrenia catatônica refratária e antecedentes de síndrome neuroléptica maligna / Olanzapine and ECT combined therapy in a refractory catatonic subtype schizophrenia patient with previous neuroleptic malignant syndrome episodes

Este artigo descreve a história clínica e o manejo de um paciente masculino adulto com esquizofrenia catatônica refratária a dois neurolépticos típicos (haloperidol e clorpromazina) e a outro agente atípico (risperidona), e com antecedente de dois episódios de síndrome neuroléptica maligna em vigência de neurolépticos típicos. Os autores optaram pela associação de eletroconvulsoterapia (ECT) e olanzapina (7,5 mg). Foram obtidos consideráveis benefícios para o paciente.

Marcador D8-17: implicações para a neuropsiquiatria / D8/17 marker: implication to neuropsychiatry

Estudos recentes sugerem uma associação entre febre reumática (FR) e transtornos do espectro obsessivo-compulsivo, o que levou à hipótese de que alterações na resposta imune pudessem ter um papel na etiologia destes últimos. Um marcador biológico que talvez identifique maior susceptibilidade para o desenvolvimento de FR e desses transtornos neuropsiquiátricos tem causado grande interesse na literatura. Trata-se do D8/17, um anticorpo monoclonal contra um antígeno de membrana de linfócitos B. Neste artigo introduzimos conhecimentos sobre o D8/17 e discutimos suas implicações como um possível marcador biológico de transtornos neuropsiquiátricos associados ou não à FR.
