This is the second part of the Brazilian S20 mental health report. The mental health working group is dedicated to leveraging scientific insights to foster innovation and propose actionable recommendations for implementation in Brazil and participating countries. In addressing the heightened mental health challenges in a post-pandemic world, strategies should encompass several key elements. This second part of the S20 Brazilian Mental Health Report will delve into some of these elements, including: the impact of climate change on mental health, the influence of environmental factors on neurodevelopmental disorders, the intersection of serious mental illness and precision psychiatry, the co-occurrence of physical and mental disorders, advancements in biomarkers for mental disorders, the use of digital health in mental health care, the implementation of interventional psychiatry, and the design of innovative mental health systems that integrate principles of innovation and human rights. Reassessing the treatment settings for psychiatric patients in general hospitals, where their mental health and physical needs are addressed, should be prioritized in mental health policy. As the S20 countries prepare for the future, we need principles that can advance innovation, uphold human rights, and strive for the highest standards in mental health care.

Generalized anxiety disorder is a highly prevalent mental disorder. Previous data indicate that more than 18 million Brazilians suffer from this condition. Traditionally, generalized anxiety disorder has been considered a mild mental health disorder, despite its links to lower life expectancy, cardiovascular disease, and suicide. The aim of this article is to combine elements of systematic and critical reviews to produce a synthesis of the best evidence about generalized anxiety disorder treatment. Systematic reviews, meta-analyses, and randomized controlled trials were included. The descriptor used in the search was “generalized anxiety disorder,” which resulted in 4,860 articles and seven other studies, of which 59 were selected. Antidepressants and benzodiazepines were indicated, as was pregabalin, and atypical antipsychotics, such as quetiapine, have been studied. Individual cognitive behavior therapy (third wave) has proven effective. There is extensive literature on many effective treatments for generalized anxiety disorder. The present review summarizes the therapeutic possibilities, emphasizing those available in Brazil. Further studies are needed to compare other available medications, assess psychotherapies and new treatments in greater depth, as well as to assess the ideal duration of therapy.

This paper tries to summarize the results of studies from different areas of knowledge supporting the idea that temperamental traits, such as “reckless/hyper-exploratory” attitudes, commonly believed to be associated with psychopathology, surprisingly turn out as adaptive under specific stress conditions. In particular, this paper analyzes an ethologic line of research on primates suggesting models for a sociobiological interpretation of mood disorders in humans; a study that found high frequencies of a genetic variance associated with bipolar disorder in people without bipolar disorder but with hyperactivity/novelty-seeking traits; the outcomes of socio-anthropological-historical surveys on the evolution of mood disorders in Western countries in the last centuries; surveys on changing societies in Africa and African migrants in Sardinia; and studies that found higher frequencies of mania and subthreshold mania among Sardinian immigrants in Latin American megacities. Although it is not unequivocally accepted that the prevalence of mood disorders has increased, it would be logical to suppose that a nonadaptive condition should have disappeared over time; mood disorders, on the contrary, persist and their prevalence might have even increased. This new interpretation could lead to counter discrimination and stigma towards people suffering from the disorder and would be a central point in psychosocial treatments in addition to pharmacological therapy. Our aim is to hypothesize that bipolar disorder, strongly characterized by these traits, may be the result of the interaction between genetic characteristics, not necessarily pathological, and specific environmental conditions rather than a mere product of an aberrant genetic profile. If mood disorders were mere nonadaptive conditions, they would have disappeared over time; however, their prevalence paradoxically persists if not even increases over time. The hypothesis that bipolar disorder may result from the interaction between genetic characteristics, not necessarily pathological, and specific environmental factors seems more credible than considering bipolar disorder as a mere product of an aberrant genetic profile.

RESUMO Objetivo: Na prática clínica, é importante diferenciar problema e conflito, porque os passos sugeridos na técnica de resolução de problemas costumam não ser suficientes para auxiliar o cliente a lidar com conflitos. Esta revisão sistemática teve como objetivos: investigar como a terapia cognitivo-comportamental (TCC) pode auxiliar na resolução de problemas e na mediação de conflito; sugerir uma estratégia que favoreça a melhor capacidade de mediar conflitos (QPD). Métodos: Foi realizada uma busca nas bases de dados: PubMed, PsycINFO, Web of Science (ISI) e Scopus. O método prisma foi utilizado, e foram selecionados para leitura na íntegra artigos experimentais. Resultados: Trezentos e sessenta e quatro ensaios clínicos aplicaram a resolução de problemas, apontando a eficácia dessa técnica juntamente com outras estratégias/intervenções da TCC. Livros-guias de TCC: não diferenciam problema e conflito; descrevem detalhadamente passos para resolução de problemas, focando na perspectiva do cliente, no momento presente e no uso da razão lógica; não abordam a mediação de conflitos pela TCC. Sugerimos uma estratégia que pode ajudar na mediação de conflitos: auxiliando na coleta/organização de informações; melhorando a comunicação – empática e assertiva; favorecendo escolhas com o intuito de causar o menor dano possível a todas as partes envolvidas no conflito. Conclusões: Para treinar terapeutas para aplicarem a resolução de problemas, há descrição detalhada dos passos a serem seguidos. Entretanto, para capacitar os terapeutas para mediarem conflitos, práticas clínicas que têm sido frequentemente descritas/utilizadas nas terapias cognitivas contextuais podem ser necessárias: aceitação psicológica, mindfulness , entender valores individuais, vivenciar/considerar a emoção em tomadas de decisão, ativar a compaixão/autocompaixão.

Abstract Humanity is sporadically subjected to leaders with deviant behavior, ego problems, or psychiatric disorders, potentially leading to social instability. Bipolar disorder is not common in all populations, but, coincidentally, studies suggest that it affected two sovereigns that were contemporaries, King George III of England, who died 201 years ago, and Queen Maria I of Portugal, who died 205 years ago. They lived during a time when Europe was in turmoil with the French Revolution and Napoleonic Wars, which also coincided with the rise of psychiatry. Both monarchs were forced to have prince regents rule in their place, due to their emotional decline, and they shared the same medical consultant, Francis Willis.

ABSTRACT An omphalocele is a defect in the closure of the abdominal wall during the embryonic stage, preventing the return of some abdominal organs to the cavity. In stillborn animals, the involvement of the liver in the omphalocele has been reported. The aim of the present study is to report the success of a partial liver resection in a female bovine at two days of age which presented an omphalocele at birth. Surgical intervention was indicated to reduce and suture the abdominal wall. During the surgical procedure, the presence of hard, reddish tissue was noted inside the sac covered by the amniotic membrane, with characteristics consistent with hepatic parenchyma. Due to the impossibility of reducing the contents added to the suggestion of tissue infection, we elected to perform a partial resection. The histopathological examination confirmed that the resected tissue was of the hepatic parenchyma. Antibiotic and systemic anti-inflammatory therapies were performed post-surgery. Fifteen days after surgery, infection was detected at the surgical site in addition to abdominal wound dehiscence; surgical reintervention was performed. On physical examination, carried out 4 months after the second operation, the heifer presented normal development for the species. In conclusion, omphalocele may contain liver. Ectopic liver is an extremely rare condition. Surgical treatment in the presented case focused on umbilicus with exploration of the abdominal cavity appeared to be sufficient.

Objective: The aim of the present study was to analyze the body sway response in specific phobia (SP) patients and healthy controls while viewing neutral, phobic, and disgusting images. Methods: The participants’ heart rate (HR) and skin conductance were also recorded during the procedure. Nineteen patients with arachnophobia and 19 healthy volunteers matched by age, gender, and years of education underwent a postural control test on a stabilometric platform. Results: The platform recorded increased body sway in the SP group when exposed to spider images (SPI). The SP group presented increases in most parameters (SD, velocity, frequency, area, p ≤ 0.05) when viewing pictures of the SPI category. Psychometric measures of subjective anxiety (State-Trait Anxiety Inventory, STAI) and physiological states (HR; skin conductance responses; spontaneous fluctuations in skin conductance) showed increased anxiety (p ≤ 0.05) in the SP group compared to healthy volunteers. High anxiety levels were observed throughout the assessment, including the task of exposure to SPI (p ≤ 0.05). No significant effect or correlation was found between skin conductance and body sway measures (p > 0.05). Conclusions: The results of the postural control test suggest the occurrence of a defensive escape response in SP, in agreement with previous evidence.

Panic disorder (PD) pathophysiology is very heterogeneous, and the discrimination of distinct subtypes could be very useful. A subtype based on respiratory symptoms is known to constitute a specific subgroup. However, evidence to support the respiratory subtype (RS) as a distinct subgroup of PD with a well-defined phenotype remains controversial. Studies have focused on characterization of the RS based on symptoms and response to CO2. In this line, we described clinical and biological aspects focused on symptomatology and CO2 challenge tests in PD RS. The main symptoms that characterize RS are dyspnea (shortness of breath) and a choking sensation. Moreover, patients with the RS tended to be more responsive to CO2 challenge tests, which triggered more panic attacks in this subgroup. Future studies should focus on discriminating respiratory-related clusters and exploring psychophysiological and neuroimaging outcomes in order to provide robust evidence to confirm RS as a distinct subtype of PD.

Abstract Introduction The objective of this study was to conduct a review of the literature covering the use of different mindfulness-based therapy approaches in treatment of mood and anxiety disorders, including mindfulness skills and mindfulness linked to emotional regulation and fear of negative appraisal. Methods A review was conducted of literature identified by searching the scientific databases PubMed and PsycINFO with the following keywords: mindfulness, mood disorders, and anxiety disorders. The search covered the past 10 years. The search returned 532 articles, 24 were selected, their full texts were read, and 16 were included in this review. Results Six articles about mindfulness-based stress reduction, four about mindfulness-based cognitive therapy, and three about fear of negative appraisal and emotional regulation were reviewed. All of the articles covered mindfulness in relation to mood and anxiety disorders. Conclusions The literature in this field suggests that mindfulness is an effective strategy for the treatment of mood and anxiety disorders and is effective in therapy protocols with different structures including virtual modalities. Use of mindfulness in scientific models continues to expand.

Objective: To ascertain lifetime prevalence of positivity to a screening questionnaire for bipolar disorders (BD) in Sardinian immigrants to Argentina and residents of Sardinia and assess whether such positivity affects quality of life (QoL) in either group. Our hypothesis is that screen positivity for BD may be more frequent in immigrants. Methods: Observational study. Subjects were randomly selected from the membership lists of associations of Sardinian immigrants in Argentina. A study carried out in Sardinia using the same methodology was used for comparison. The Mood Disorder Questionnaire was used to screen for mania/hypomania and the Short-Form Health Survey-12 to measure QoL. Results: A higher prevalence of manic/hypomanic episodes was found in Sardinian immigrants to Argentina (p < 0.0001; odds ratio = 3.0, 95% confidence interval 1.87-4.77). Positivity at screening was associated with a lower QoL both in Sardinian immigrants to Argentina and in residents of Sardinia. Conclusions: To the best of our knowledge, this is the first study to show a higher lifetime prevalence of manic/hypomanic episodes in a general-population sample of individuals who migrated to a foreign country. Our results are in agreement with the hypothesis that hyperactive/novelty-seeking features may represent an adaptive substrate in certain conditions of social change.

Objective: To investigate the reactions of women with driving phobia to a therapeutic program of scheduled virtual reality exposure treatment (VRET) sessions. Methods: The study intervention consisted of a computer game with car-driving scenarios that included several traffic situations. We investigated the participants’ sense of presence, subjective distress, and physiological responses during eight virtual-reality exposures. We also evaluated clinical characteristics, driving cognitions, and quality of life in the participants. Results: Thirteen women were selected. Eight were able to complete the protocol. After VRET, there was a decrease in the frequency of distorted thoughts and state anxiety scores, as well as a slight improvement in quality of life. Subjective discomfort scores, heart rate variation, and sense of presence scores confirmed that there was sense of presence in the virtual reality environment. Conclusion: All patients showed some degree of improvement and demonstrated different levels of anxiety in subsequent in vivo driving experiences. Our findings suggest that VRET could be used to facilitate in vivo exposure, because it can induce presence/immersion and reduce anxiety in patients with specific phobia. Furthermore, VRET is not associated with any type of risk.

Objective: To present the most relevant findings regarding the Brazilian Medical Association guidelines for the diagnosis and differential diagnosis of panic disorder. Methods: We used the methodology proposed by the Brazilian Medical Association for the Diretrizes Project. The MEDLINE (PubMed), Scopus, Web of Science, and LILACS online databases were queried for articles published from 1980 to 2012. Searchable questions were structured using the PICO format (acronym for “patient” [or population], “intervention” [or exposure], “comparison” [or control], and “outcome”). Results: We present data on clinical manifestations and implications of panic disorder and its association with depression, drug abuse, dependence and anxiety disorders. In addition, discussions were held on the main psychiatric and clinical differential diagnoses. Conclusions: The guidelines are proposed to serve as a reference for the general practitioner and specialist to assist in and facilitate the diagnosis of panic disorder.

INTRODUCTION: Respiratory changes are associated with anxiety disorders, particularly panic disorder (PD). The stimulation of respiration in PD patients during panic attacks is well documented in the literature, and a number of abnormalities in respiration, such as enhanced CO2 sensitivity, have been detected in PD patients. Investigators hypothesized that there is a fundamental abnormality in the physiological mechanisms that control breathing in PD. METHODS: The authors searched for articles regarding the connection between the respiratory system and PD, more specifically papers on respiratory challenges, respiratory subtype, and current mechanistic concepts. CONCLUSIONS: Recent evidences support the presence of subclinical changes in respiration and other functions related to body homeostasis in PD patients. The fear network, comprising the hippocampus, medial prefrontal cortex, amygdala and its brainstem projections, may be abnormally sensitive in PD patients, and respiratory stimulants like CO2 may trigger panic attacks. Studies indicate that PD patients with dominant respiratory symptoms are particularly sensitive to respiratory tests compared to those who do not manifest dominant respiratory symptoms, representing a distinct subtype. The evidence of changes in several neurochemical systems might be the expression of the complex interaction among brain circuitsINTRODUÇÃO: As anormalidades respiratórias estão associadas a transtornos de ansiedade, especialmente ao transtorno do pânico (TP). A estimulação respiratória em pacientes com TP durante os ataques de pânico está bem documentada na literatura, e vários problemas respiratórios como uma elevada sensibilidade ao CO2 foram detectados em pacientes com TP. Os pesquisadores levantam a hipótese de que existe um distúrbio fundamental nos mecanismos fisiológicos que controlam a respiração no TP. MÉTODOS: Os autores pesquisaram artigos sobre a conexão entre o sistema respiratório e TP, mais especificamente artigos sobre testes respiratórios, subtipo respiratório e conceitos mecanicistas atuais. CONCLUSÕES: Evidências recentes apoiam a existência de alterações subclínicas na respiração e em outras funções relacionadas à homeostase corporal em pacientes com TP. O circuito do medo, composto pelo hipocampo, córtex pré-frontal medial, amígdala e suas projeções para o tronco encefálico, pode estar anormalmente sensível em pacientes com TP, e os estimulantes respiratórios, como o CO2, podem desencadear ataques de pânico. Estudos indicam que os pacientes com TP que apresentam sintomas respiratórios dominantes são particularmente sensíveis a testes respiratórios, comparados àqueles que não manifestam sintomas respiratórios dominantes, representando um subtipo distinto. A constatação de anormalidades em vários sistemas neuroquímicos pode ser a expressão da interação complexa entre os circuitos cerebrais.

OBJECTIVES: To review and describe studies of the non-psychotomimetic constituent of Cannabis sativa, cannabidiol (CBD), as an anxiolytic drug and discuss its possible mechanisms of action. METHOD: The articles selected for the review were identified through searches in English, Portuguese, and Spanish in the electronic databases ISI Web of Knowledge, SciELO, PubMed, and PsycINFO, combining the search terms "cannabidiol and anxiolytic", "cannabidiol and anxiolytic-like", and "cannabidiol and anxiety". The reference lists of the publications included, review articles, and book chapters were handsearched for additional references. Experimental animal and human studies were included, with no time restraints. RESULTS: Studies using animal models of anxiety and involving healthy volunteers clearly suggest an anxiolytic-like effect of CBD. Moreover, CBD was shown to reduce anxiety in patients with social anxiety disorder. CONCLUSION: Future clinical trials involving patients with different anxiety disorders are warranted, especially of panic disorder, obsessive-compulsive disorder, social anxiety disorder, and post-traumatic stress disorders. The adequate therapeutic window of CBD and the precise mechanisms involved in its anxiolytic action remain to be determined.OBJETIVOS: Revisar e descrever os estudos do constituinte não psicotomimético da Cannabis sativa, o canabidiol (CBD), como ansiolítico e discutir seus possíveis mecanismos de ação. MÉTODO: Os artigos selecionados para a presente revisão foram identificados por meio de busca eletrônica em inglês, português e espanhol nos bancos de dados ISI Web of Knowledge, SciELO, PubMed e PsycINFO e combinando os termos "canabidiol e ansiolíticos", "canabidiol e semelhante ao ansiolítico" e "canabidiol e ansiedade". Foram também revisadas as listas de referências dos artigos incluídos, de revisões da literatura e de capítulos de livro. Incluímos trabalhos experimentais em humanos e em animais, sem limite de tempo. RESULTADOS: Estudos com modelos animais de ansiedade e envolvendo voluntários saudáveis sugerem claramente que o CBD possui efeitos ansiolíticos. Além disso, o CBD mostrou-se capaz de reduzir a ansiedade em pacientes com transtorno de ansiedade social. CONCLUSÃO: Futuros ensaios clínicos com pacientes portadores de diferentes transtornos de ansiedade, em especial pacientes com transtorno do pânico, obsessivo-compulsivo, ansiedade social e estresse pós-traumático, são oportunos. Além disso, ainda é necessário determinar a adequada faixa terapêutica do CBD e os exatos mecanismos envolvidos nessa ação ansiolítica.

INTRODUCTION: There is substantial evidence regarding the impact of negative life events during childhood on the aetiology of psychiatric disorders. We examined the association between negative early life events and social anxiety in a sample of 571 Spanish University students. METHODS: In a cross-sectional survey conducted in 2007, we collected data through a semistructured questionnaire of sociodemographic variables, personal and family psychiatric history, and substance abuse. We assessed the five early negative life events: (i) the loss of someone close, (ii) emotional abuse, (iii) physical abuse, (iv) family violence, and (v) sexual abuse. All participants completed the Liebowitz Social Anxiety Scale. RESULTS: Mean (SD) age was 21 (4.5), 75% female, LSAS score was 40 (DP = 22), 14.2% had a psychiatric family history and 50.6% had negative life events during childhood. Linear regression analyses, after controlling for age, gender, and family psychiatric history, showed a positive association between family violence and social score (p = 0.03). None of the remaining stressors produced a significant increase in LSAS score (p > 0.05). CONCLUSION: University students with high levels of social anxiety presented higher prevalence of negative early life events. Thus, childhood family violence could be a risk factor for social anxiety in such a population.INTRODUÇÃO: Existem evidências substanciais sobre o impacto de eventos negativos da vida durante a infância na etiologia dos transtornos psiquiátricos. Examinamos a associação entre os eventos negativos ocorridos na infância e a ansiedade social em uma amostra de 571 estudantes universitários espanhóis. MÉTODOS: Em um estudo transversal realizado em 2007, foram coletados os dados de variáveis sociodemográficas, história psiquiátrica pessoal e familiar e abuso de substâncias por meio de um questionário semiestruturado e avaliamos cinco eventos negativos ocorridos na infância: (i) a perda de alguém próximo, (ii) abuso emocional, (iii) abuso físico, (iv) violência familiar e (v) abuso sexual. Todos os participantes preencheram a escala de Liebowitz para ansiedade social. RESULTADOS: A média (DP) de idade foi de 21 anos (4,5); 75% eram do sexo feminino; o escore na LSAS foi 40 (DP = 22); 14,2% tinham história psiquiátrica familiar e 50,6% tiveram eventos negativos durante a infância. A análise de regressão linear, após o controle para idade, sexo e história psiquiátrica familiar, mostraram associação positiva entre violência familiar e escore de ansiedade social (p = 0,03). Nenhum dos fatores estressores restantes produziu aumento significativo no escore da LSAS (p > 0,05). CONCLUSÃO: Os estudantes universitários com altos níveis de ansiedade social apresentaram prevalência maior de eventos negativos precoces. Portanto, a violência familiar na infância pode ser um fator de risco para ansiedade social em tal população.

OBJECTIVE: Specific phobia (SP) is characterized by irrational fear associated with avoidance of specific stimuli. In recent years, neuroimaging techniques have been used in an attempt to better understand the neurobiology of anxiety disorders. The objective of this study was to perform a systematic review of articles that used neuroimaging techniques to study SP. METHOD:A literature search was conducted through electronic databases, using the keywords: imaging, neuroimaging, PET, spectroscopy, functional magnetic resonance, structural magnetic resonance, SPECT, MRI, DTI, and tractography, combined with simple phobia and specific phobia. One-hundred fifteen articles were found, of which 38 were selected for the present review. From these, 24 used fMRI, 11 used PET, 1 used SPECT, 2 used structural MRI, and none used spectroscopy. RESULT: The search showed that studies in this area were published recently and that the neuroanatomic substrate of SP has not yet been consolidated. CONCLUSION: In spite of methodological differences among studies, results converge to a greater activation in the insula, anterior cingulate cortex, amygdala, and prefrontal and orbitofrontal cortex of patients exposed to phobia-related situations compared to controls. These findings support the hypotheses of the hyperactivation of a neuroanatomic structural network involved in SP.A Fobia Específica (SP do inglês) é caracterizada por medos irracionais associados à evitação de estímulos específicos. Nos últimos anos, técnicas de neuroimagem vêm sendo empregadas na tentativa de melhor compreender a neurobiologia dos transtornos de ansiedade. O objetivo do presente estudo é realizar uma revisão sistemática dos artigos que utilizaram neuroimagem para estudar a SP. A busca na literatura foi realizada por intermédio de indexadores eletrônicos, utilizando-se as palavras-chave: imaging, neuroimaging, PET, spectroscopy, functional magnetic ressonance, structural magnetic ressonance, SPECT, MRI, DTI e tractography, cruzadas individualmente com os termos simple phobia e specific phobia. Foram encontrados 115 artigos, sendo 38 deles selecionados para a presente revisão. Desses, 24 usaram fMRI, 11 usaram PET, 1 usou SPECT, 2 usaram MRI estrutural e nenhum artigo de espectroscopia. Verifica-se que os estudos na área foram publicados recentemente e que, até o momento, o substrato neuroanatômico deste transtorno não está consolidado. Apesar das diferenças metodológicas entre os estudos, os resultados convergem para maior ativação na ínsula, cíngulo anterior, amídala e córtex préfrontal e orbitofrontal dos pacientes expostos a situações phobia related quando comparados aos controles. Esses achados reforçam hipóteses a respeito da hiperativação de uma determinada rede de estruturas neuroanatômicas envolvidas no transtorno de SP.

INTRODUÇÃO: O transtorno de ansiedade social (TAS) é o transtorno de ansiedade mais comum, freqüentemente sem remissões, sendo comumente associado com importante prejuízo funcional e psicossocial. A Associação Médica Brasileira (AMB), através do "Projeto Diretrizes", busca desenvolver consensos de diagnóstico e tratamento para as doenças mais comuns. O objetivo deste trabalho é apresentar os achados mais relevantes das diretrizes relativas ao tratamento do TAS, servindo de referência para o médico generalista e especialista. MÉTODO: O método utilizado foi o proposto pela AMB. A busca foi realizada nas bases de dados do MEDLINE (PubMed), Scopus, Web of Science e Lilacs, entre 1980 e 2010. A estratégia utilizada baseou-se em perguntas estruturadas na forma P.I.C.O (acrônimo das iniciais "paciente ou população"; "intervenção, indicador ou exposição"; "controle ou comparação" e; "outcome ou desfecho"). RESULTADOS: Estudos evidenciam que o tratamento farmacológico de primeira linha para adultos e crianças são os inibidores seletivos de recaptação de serotonina e os inibidores de recaptação de serotonina e noradrenalina, enquanto que a terapia cognitivo-comportamental é apontada como melhor tratamento psicoterápico. Além disso, algumas comorbidades psiquiátricas foram associadas a uma pior evolução do TAS. CONCLUSÕES: Apesar da alta prevalência, o TAS acaba por não receber a devida atenção e tratamento. A melhor escolha para o tratamento de adultos é a associação psicoterapia cognitivo-comportamental com inibidores seletivos de recaptação de serotonina e os inibidores de recaptação de serotonina e noradrenalina. Outras opções como benzodiazepínicos ou inibidores da monoamino-oxidase devem ser usados como segunda e terceira opção respectivamente.INTRODUCTION: Social anxiety disorder (SAD) is the most common anxiety disorder, usually with no remission, and is commonly associated with significant functional and psychosocial impairment. The Brazilian Medical Association (BMA), with the project named Diretrizes (Guidelines, in English), seeks to develop consensus for the diagnosis and treatment of common diseases. The aim of this article is to present the most important findings of the guidelines on the treatment of SAD, serving as a reference for the general practitioner and specialist. METHOD: The method used was proposed by the BMA. The search was conducted in the databases of MEDLINE (PubMed), Scopus, Web of Science and LILACS, between 1980 and 2010. The strategy used was based on structured questions as PICO (acronym formed by the initials of "patient or population", "intervention, display or exhibition", "control or comparison" and "outcome"). RESULTS: Studies show that the first-line pharmacological treatment for adults and children are serotonin selective reuptake inhibitors and serotonin and norepinephrine reuptake inhibitors, whereas cognitive-behavioral therapy is considered the best psychotherapeutic treatment. Moreover, some psychiatric comorbidities were associated with a worse outcome of SAD. CONCLUSIONS: Despite its high prevalence, SAD does not receive adequate attention and treatment. The best choice for the treatment of adults is a combination of cognitive-behavioral psychotherapy with serotonin selective reuptake inhibitors and serotonin and norepinephrine reuptake inhibitors. Other options as benzodiazepines or monoamine oxidase inhibitors must be used as second and third choices, respectively.

Objectivo: comparar os scores dos diversos domínios de qualidade de vida e quadro clínico entre os doentes com subtipos respiratório e não respiratório de transtorno de pânico (TP) em tratamento no Laboratório de Pânico e Respiração da UFRJ. Método: estudo transversal com 32 doentes com TP com ou sem comorbidades em tratamento ambulatorial, selecionados consecutivamente e diagnosticados através do MINI v.4.4. Destes, 12 (37,5%) apresentam o subtipo respiratório (SR) e 20 (62,5%) o subtipo não respiratório (SN), de acordo com Briggs et al. Resultados: Em relação aos índices de qualidade de vida, houve apenas diferença no domínio psicológico, sendo que os doentes do subgrupo SN apresentaram piores scores. Os diferentes subtipos de TP (SR e SN) não apresentaram diferenças significativas quanto à distribuição por género, idade, escolaridade, ocupação, estado civil, tabagismo e comorbidades. Clinicamente também não foram encontradas diferenças significativas nos scores de ansiedade, nem de gravidade do TP (BAI, STAI -T, STAI -S, PAS), bem como não se observaram diferenças quanto à idade de início do transtorno ou tempo de evolução da doença. Conclusão: Doentes do subtipo não respiratório, que apresentam índices semelhantes de ansiedade e gravidade do TP, quando em tratamento, apresentam piores scores de qualidade de vida psicológica do que os do subtipo respiratório.Aim: to compare the scores of the WHOQOL quality of life domains with the clinical features of patients with respiratory and non-respiratory panic disorders (PD) treated at the UFRJ Panic and Respiration Laboratory. Method: cross sectional study. Thirty-two PD outpatients under treatment were consecutively selected and evaluated by the MINI v.4.4. They were divided into two different groups according to Briggs et al. classification of respiratory and non-respiratory PD subtypes. Twelve (37.5%) patients had the respiratory subtype (SR) and 20 (62.5%) the non-respiratory subtype (SN). Results: the SN patients presented worse scores in the psychological domain of the WHOQOL. There were no differences between groups in gender, age, level of schooling, occupational status, marital status, smoking and comorbidities. There were no differences in the anxiety questionnaires and PD questionnaire (BAI, STAI-T, STAI-S, PAS) scores and in the age at the beginning of the disorder and the disorder’s duration. Conclusion: non-respiratory subtype patients presented worse scores in the psychological domain of WHOQOL than the respiratory subtype group, when they had similar anxiety and PD scores.

Clinica-mente também não foram encontradas diferenças significativas nos scores de ansiedade, nem de gravidade do TP (BAI, STAI-T, STAI-S, PAS), bem como não se observaram diferenças quanto à idade de início do transtorno ou tempo de evolução da doença.Conclusão: Doentes do subtipo não respiratório, que apresentam índices semelhantes de ansiedade e gravidade do TP, quando em tratamento, apresentam piores scores de qualidade de vida psicológica do que os do subtipo respiratório.Rev Port Pneumol 2009; XV (5): 859-874 Abstract: Aim: to compare the scores of the WHOQOL quality of life domains with the clinical features of patients with respiratory and non-respiratory panic disorders (PD) treated at the UFRJ Panic and Respiration Laboratory.Method: cross sectional study. Thirty-two PD outpatients under treatment were consecutively selected and evaluated by the MINI v.4.4. They were divided into two different groups according to Briggs et al. classification of respiratory and non-respiratory PD subtypes. Twelve (37.5%) patients had the respiratory subtype (SR) and 20 (62.5%) the non-respiratory subtype (SN).Results: the SN patients presented worse scores in the psychological domain of the WHOQOL. There were no differences between groups in gender, age, level of schooling, occupational status, marital status, smoking and comorbidities. There were no differences in the anxiety questionnaires and PD questionnaire (BAI, STAI-T, STAI-S, PAS) scores and in the age at the beginning of the disorder and the dis-orderâs duration.Conclusion: non-respiratory subtype patients presented worse scores in the psychological domain of WHOQOL than the respiratory subtype group, when they had similar anxiety and PD scores.Rev Port Pneumol 2009; XV (5): 859-874 Palavras-chave: Ansiedade, transtorno de pânico, qualidade de vida, subtipo respiratório, Key-words: Anxiety, panic disorder, quality of life, respiratory subtype

OBJECTIVE: Our aim was to identify the personality traits in patients with panics disorder, major depression and with both disorders (comorbidity). METHOD: Diagnoses were made with the Structured Clinical Interview for DSM-IV before the treatment, and the personality evaluation with the Maudsley Personality Inventory was made during the follow-up. Four groups were analyzed: a control group (n = 30), a major depression without panic disorder group (n = 45); a panic disorder without major depression group (n = 56) and a comorbidity group (n = 21), with major depression and panic disorder, simultaneously. RESULTS: All disorder groups had significantly higher neuroticism means when compared to the control group. The highest mean was in the comorbidity group, followed by the major depression group and the panic disorder group. The difference of neuroticism means between the comorbidity group and the panic disorder group also reached statistical significance. The lowest extraversion mean was in the comorbidity group, followed by the major depression group, the panic disorder group, and the control group. Compared to normal controls, extraversion was significantly low in the comorbidity and major depression groups. CONCLUSION: In our sample, there was a continuum of personality traits between panic disorder and major depression and, the co-occurrence of these disorders was associated with accentuated personality traits.OBJETIVO: Identificar os traços de personalidade presentes em pacientes com transtorno do pânico, depressão maior e comorbidade. MÉTODO: Os diagnósticos foram feitos com o Structured Clinical Interview para o DSM-IV antes do início do tratamento, e a avaliação dos traços de personalidade com o Maudsley Personality Inventory foi feita durante o acompanhamento desses pacientes. Quatro grupos foram comparados: um grupo controle (n = 30), um grupo de depressão maior sem transtorno do pânico (n = 45); um grupo de transtorno do pânico sem depressão maior (n = 56) e um grupo de comorbidade (n = 21), com transtorno do pânico e depressão maior, simultaneamente. RESULTADOS: Todos os grupos de pacientes tiveram médias de neuroticismo significativamente maiores quando comparados ao grupo controle. A maior média foi no grupo de comorbidade, seguida pelas dos grupos de depressão maior e transtorno do pânico. A diferença de neuroticismo entre o grupo de comorbidade e de transtorno do pânico também foi estatisticamente significativa. Entre os grupos de pacientes, a menor média de extroversão foi a do grupo de comorbidade, seguida pelas de depressão maior e transtorno do pânico. Quando comparados ao grupo controle, apenas os grupos de comorbidade e depressão maior tiveram extroversão significativamente mais baixa. CONCLUSÃO: Na nossa amostra, houve uma continuidade de traços de personalidade entre o transtorno do pânico e a depressão maior, e a sobreposição de sintomas de pânico-agorafobia e de depressão estava associada a traços de personalidade acentuados.

OBJECTIVE: To compare nocturnal and diurnal panic attacks in a cross-sectional study and in a longitudinal prospective short-term follow-up. METHODS: We selected 57 panic disorder (PD) subjects (DSM-IV) and rated them with the Panic Disorder Severity Scale (PDSS) at baseline and after 30 days of treatment with nortriptyline, and with the Eysenck Personality Inventory and the Brown Attention Deficit Disorder (ADD) Scale at baseline. RESULTS: The sample was divided into a nocturnal and diurnal panic attack (NDPA) group - 57.9% (n = 33) - and a diurnal panic attack (DPA) group - 42.1% (n = 24). The groups showed a similar mean age at onset of PD and a pattern of prominent respiratory symptoms. The PDSS did not differ between the groups following short-term treatment (p = 0.451). There were also neither significant differences in Neuroticism (p = 0.094) and Extroversion (p = 0.269) nor in the Brown ADD Scale (p = 0.527). CONCLUSION: In our study, patients with both nocturnal and diurnal panic attacks showed similar features in their phenomenology and short-term outcome when compared to pure diurnal panic attacks patients.OBJETIVO: Comparar ataques de pânico noturnos e diurnos em um estudo de acompanhamento prospectivo de curto prazo MÉTODOS: Selecionamos 57 indivíduos com transtorno do pânico (TP) segundo o DSM-IV e os classificamos com a Panic Disorder Severity Scale (PDSS) na linha de base e após 30 dias de tratamento com nortriptilina, e com o Eysenck Personality Inventory e a escala Brown Attention Deficit Disorder (ADD) na linha de base. RESULTADOS: A amostra foi dividida em um grupo com ataques de pânico noturnos e diurnos (NDPA) - 57,9% (n = 33) - e um grupo com ataques de pânico diurnos (DPA) - 42,1% (n = 24). Os grupos tiveram idades médias de início de transtorno do pânico e um padrão de sintomas respiratórios proeminentes similares. A Panic Disorder Severity Scale não apresentou diferenças entre os grupos após tratamento de curto prazo (p = 0,451). Tampouco houve diferenças significativas em Neuroticismo (p = 0,094) e Extroversão (p = 0,269) e na escala Brown Attention Deficit Disorder (p = 0,527). CONCLUSÃO: Em nosso estudo, os pacientes com ataques de pânico noturnos e diurnos tiveram características similares quanto aos seus resultados fenomenológicos e resultados em curto prazo em comparação com pacientes que tiveram somente ataques diurnos de pânico.

OBJETIVOS: O Transtorno de Pânico (TP) é um transtorno de ansiedade que permite um estudo comparativo de modelos animais visando à elucidação dos circuitos cerebrais envolvidos na sua gênese, embora estes ainda tenham sido pouco discutidos. MÉTODOS: Os autores realizam uma revisão da literatura sobre neurobiologia e neuroanatomia do TP. RESULTADOS: Uma revisão de dados demonstra a existência de uma "rede de medo", que tem como ponto principal o núcleo central da amígdala e compreende o hipotálamo, o tálamo, o hipocampo, a substância cinzenta periaquedutal, o locus ceruleus e outras estruturas do tronco cerebral. Sua presença é evidenciada em estudos de modelos animais de estados emocionais e comportamentais, e sua presença e importância podem ser extrapoladas para o TP em humanos. CONCLUSÃO: Esta rede de medo pode permitir que novos avanços e estudos utilizando técnicas de neuroimagem e/ou psicofármacos possam auxiliar na maior elucidação da circuitos cerebrais do TP.OBJECTIVES: Animal model studies may allow greater elucidation of the cerebral circuits involved in the genesis of panic disorder (PD), but these studies have not yet been fully analyzed. METHODS: The authors review recent literature on the neurobiology and neuroanatomy of PD. RESULTS: In this update, the authors present a revision of data that demonstrates the existence of a "fear network", which has as its main point the central nucleus of the amygdale and includes the hypothalamus, the thalamus, the hippocampus, the periaqueductal gray region, the locus ceruleus and other brainstem structures. Its existence is evidenced in animal studies of emotional and behavioral states, and its presence and importance can be extrapolated to the study of PD in humans. CONCLUSION: This fear network can allow new progresses and studies using neuroimaging techniques and/or psychopharmacological trials, further elucidating the cerebral circuits of PD.

OBJECTIVE: There is evidence that asthma is associated with increased frequency of psychiatric symptoms and mental disorders. Our aim was to assess the frequency of anxiety and depressive disorders in a sample of asthmatic outpatients and observe if there is any relationship between this comorbidity and the severity of asthma. METHOD: Sixty-two consecutive patients of two outpatient asthma clinics located in university hospitals were evaluated. Psychiatric diagnoses were assessed with the Mini-International Neuropsychiatric Interview 4.4 Version. RESULTS: Twenty-seven patients (43.5%) met criteria for at least one psychiatric diagnosis. The most frequent diagnoses were major depression (24%), generalized anxiety disorder (20.9%) and panic disorder/agoraphobia spectrum disorders (17.7%). We found no significant differences in the prevalence of anxiety disorders and depression between the groups with mild/moderate and severe asthma. Despite the high frequency of depression and anxiety disorders, only 4 (6.5%) patients were under psychiatric treatment and 13 (20.9%) patients were taking benzodiazepines. Twelve of 15 (80%) patients who reported present use of psychotropic medication were not under psychiatric treatment at the moment of the study. CONCLUSIONS: Our results support the high morbidity of anxiety and depressive disorders in asthmatic patients, independent of the severity of asthma.
