Relação entre eventos vitais adversos e estratégias de enfrentamento com o transtorno de pânico

Research literature and clinical experience shows that panic patients are often able to identify stressors that preceded the onset of their first attacks. In this study we investigated the relation between life events, coping skills, and panic disorder. METHODS: Forty-tree panic patients were compared with 29 control subjects regarding the occurrence and the impact of stressful life events in a 1-year period preceding the onset of panic attacks using the Social Readjustment Rating Scale and London Life Event and Difficulty Schedule. Coping skills were measured using the Ways of Coping Questionnaire. RESULTS: No differences were observed between panic patients and controls regarding the number of reported stressful life events in the previous year. Panic patients compared to controls reported loss of social support as the most meaningful class of events significantly more often. In response to stressful situations, panic patients more often used coping skills judged as ineffective. CONCLUSIONS: The present study suggests that the type of life event and the coping skills used in response to them, more than the occurrence of stressful events itself, may be associated with the onset of panic disorder.Os relatos da literatura e a experiência clínica tem demonstrado que pacientes com transtorno de pânico são capazes de identificar estressores que precederam o primeiro ataque de pânico. O objetivo deste trabalho é investigar a relação entre eventos vitais, estratégias de enfrentamento a estresse e transtorno de pânico. MÉTODO: Foram comparados 43 pacientes com transtorno de pânico com 29 sujeitos controle no que diz respeito a ocorrência e impacto dos eventos vitais estressores no ano que precedeu o primeiro ataque de pânico. Para tanto utilizou-se a Escala de Reajustamento Social e London Life Event and Difficulty Schedule. As estratégias de enfrentamento foram avaliadas pelo Inventário de Estratégias de Coping. RESULTADOS: O número de eventos vitais estressores relatados por ambos os grupos era estatísticamente equivalente. Os sujeitos do grupo experimental mas não os do grupo controle relataram perda de suporte social como a mais importante classe de eventos vitais. As estratégias de enfrentamento utilizadas em resposta aos eventos estressores foram pouco efetivas e desadaptadas, diferentemente do grupo controle. CONCLUSÕES: O presente estudo indica que não é o número de eventos vitais que determina a relevância de sua ocorrência para os pacientes de pânico, mas as estratégias de enfrentamento utilizadas, bem como o significado adverso atribuído aos eventos e o impacto desses eventos em suas vidas

O uso do cloridrato de betanecol no tratamento da disfunção orgásmica induzida pela clomipramina em pacientes do sexo masculino

PURPOSE: To investigate whether bethanecol chloride may be an alternative for the clinical management of clomipramine-induced orgasmic dysfunction, reported to occur in up to 96% of male users. METHODS: In this study, 12 fully remitted panic disorder patients, complaining of severe clomipramine-induced ejaculatory delay, were randomly assigned to either bethanecol chloride tablets (20 mg, as needed) or placebo in a randomized, double-blind, placebo-controlled, two-period crossover study. A visual analog scale was used to assess severity of the orgasmic dysfunction. RESULTS: A clear improvement was observed in the active treatment period. No placebo or carry-over effects were observed. CONCLUSION: These findings suggest that bethanecol chloride given 45 minutes before sexual intercourse may be useful for clomipramine-induced orgasmic dysfunction in males.OBJETIVO: Investigar se o uso do cloridato de betanecol é uma alternativa útil no manejo clínco da disfunção orgásmica induzida pela clomipramina, relatada por até 96 % dos usuários do sexo masculino. MÉTODOS: Foram estudados 12 pacientes do sexo masculino em remissão completa de transtorno de pânico porém com queixas de disfunção orgásmica grave secundária ao uso da clomipramina. Os pacientes foram aleatoriamente distribuídos ao tratamento com cloridrato de betanecol (20 mg quando necessário) ou placebo em um estudo duplo cego "crossover" de dois períodos. RESULTADOS: Foi observado um benefício claro no período de uso da droga ativa. Não foram observados efeito placebo ou "carry-over" nos pacientes inicialmete alocados ao medicamento ativo. CONCLUSÕES: Os resultados deste estudo sugerem que o cloridato de betanecol, usado em doses únicas, 45 minutos antes da relação sexual, pode ser útil em pacientes do sexo masculino apresentado disfunção orgásmica secundária ao uso da clomipramina

Endophenotypes and serotonergic polymorphisms associated with treatment response in obsessive-compulsive disorder

OBJECTIVES: Approximately 40-60% of obsessive-compulsive disorder patients are nonresponsive to serotonin reuptake inhibitors. Genetic markers associated with treatment response remain largely unknown. We aimed (1) to investigate a possible association of serotonergic polymorphisms in obsessive-compulsive disorder patients and therapeutic response to selective serotonin reuptake inhibitors and (2) to examine the relationship between these polymorphisms and endocrine response to intravenous citalopram challenge in responders and non-responders to serotonin reuptake inhibitors and in healthy volunteers. METHODS: Patients with obsessive-compulsive disorder were classified as either responders or non-responders after long-term treatment with serotonin reuptake inhibitors, and both groups were compared with a control group of healthy volunteers. The investigated genetic markers were the G861C polymorphism of the serotonin receptor 1D&#946; gene and the T102C and C516T polymorphisms of the serotonin receptor subtype 2A gene. RESULTS: The T allele of the serotonin receptor subtype 2A T102C polymorphism was more frequent among obsessive-compulsive disorder patients (responders and non-responders) than in the controls (p<0.01). The CC genotype of the serotonin receptor subtype 2A C516T polymorphism was more frequent among the non-responders than in the responders (p<0.01). The CC genotype of the serotonin receptor subtype 1D&#946; G681C polymorphism was associated with higher cortisol and prolactin responses to citalopram (p<0.01 and p<0.001, respectively) and with a higher platelet-rich plasma serotonin concentration among the controls (p<0.05). However, this pattern was not observed in the non-responders with the same CC genotype after chronic treatment with serotonin reuptake inhibitors. This CC homozygosity was not observed in the responders

Traços de personalidade e resposta terapêutica no transtorno obsessivo-compulsivo

OBJECTIVE: Comorbidity with personality disorders in obsessive-compulsive patients has been widely reported. About 40% of obsessive-compulsive patients do not respond to first line treatments. Nevertheless, there are no direct comparisons of personality traits between treatment-responsive and non-responsive patients. This study investigates differences in personality traits based on Cloninger's Temperament and Character Inventory scores between two groups of obsessive-compulsive patients classified according to treatment outcome: responders and non-responders. METHOD: Forty-four responsive and forty-five non-responsive obsessive-compulsive patients were selected. Subjects were considered treatment-responsive (responder group) if, after having received treatment with any conventional therapy, they had presented at least a 40% decrease in the initial Yale-Brown Obsessive Compulsive Scale score, had rated "better" or "much better" on the Clinical Global Impressions scale; and had maintained improvement for at least one year. Non-responders were patients who did not achieve at least a 25% reduction in Yale-Brown Obsessive Compulsive Scale scores and had less than minimal improvement on the Clinical Global Impressions scale after having received treatment with at least three selective serotonin reuptake inhibitors (including clomipramine), and at least 20 hours of cognitive behavioral therapy. Personality traits were assessed using Temperament and Character Inventory. RESULTS: Non-responders scored lower in self-directedness and showed a trend to score higher in persistence than responders did. CONCLUSION: This study suggests that personality traits, especially self-directedness, are associated with poor treatment response in obsessive-compulsive patients.OBJETIVO: Comorbidade com transtornos de personalidade tem sido extensamente descrita no transtorno obsessivo-compulsivo. Aproximadamente 40% dos pacientes com transtorno obsessivo-compulsivo não respondem a tratamentos de primeira linha. Não obstante, não existem estudos comparando diretamente traços de personalidade entre pacientes responsivos e refratários ao tratamento do transtorno obsessivo-compulsivo. Este estudo investiga diferenças nos traços da personalidade baseados no Inventário de Temperamento e Caráter de Cloninger (TCI) entre dois grupos de pacientes com transtorno obsessivo-compulsivo classificados segundo desfecho terapêutico: responsivos e refratários. MÉTODO: Quarenta e cinco pacientes refratários e 44 responsivos foram selecionados. Os indivíduos foram considerados responsivos se, após tratamento com terapêutica convencional, apresentaram diminuição de ao menos 40% no escore inicial da Yale-Brown Obsessive Compulsive Scale, foram classificados como "melhor" ou "muito melhor" na Clinical Global Impressions; e mantiveram melhora por pelo menos um ano. Os refratários eram os pacientes que não atingiram redução de ao menos 25% na Yale-Brown Obsessive Compulsive Scale e tiveram a melhoria menor que "mínima" na Clinical Global Impressions após o tratamento com ao menos três inibidores seletivos da recaptura de serotonina, incluindo clomipramina, e ao menos 20 horas da terapia cognitiva-comportamental. Os traços da personalidade foram avaliados através do Temperament and Character Inventory. RESULTADOS: Refratários pontuaram menos em autodirecionamento e tenderam a pontuar mais em persistência. CONCLUSÃO: Este estudo sugere que os traços de personalidade, especialmente autodirecionamento, estão associados com a resposta pobre do tratamento em pacientes com transtorno obsessivo-compulsivo.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP, The State of São Paulo Research Foundation)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPQ), Brazilian Council for Scientific and Technological Developmen

Benzodiazepine use in Sao Paulo, Brazil

OBJECTIVES: To report the prevalence and factors associated with the use of benzodiazepines in the general population and those with a mental health condition in the metropolitan area of Sa˜o Paulo, Brazil. METHODS: 5,037 individuals from the Sao Paulo Megacity Mental Health Survey data were interviewed using the Composite International Diagnostic Interview, designed to generate DSM-IV diagnoses. Additionally, participants were asked if they had taken any medication in the previous 12 months for the treatment of any mental health condition. RESULTS: The prevalence of benzodiazepine use ranged from 3.6% in the general population to 7.8% among subjects with a mental health condition. Benzodiazepine use was more prevalent in subjects that had been diagnosed with a mood disorder as opposed to an anxiety disorder (14.7% vs. 8.1%, respectively). Subjects that had been diagnosed with a panic disorder (33.7%) or bipolar I/II (23.3%) reported the highest use. Individuals aged X50 years (11.1%), those with two or more disorders (11.2%), those with moderate or severe disorders (10%), and those that used psychiatric services (29.8%) also reported higher use. CONCLUSION: These findings give an overview of the use of benzodiazepines in the general population, which will be useful in the public health domain. Benzodiazepine use was higher in those with a mental health condition, with people that had a mood disorder being the most vulnerable. Furthermore, females and the elderly had high benzodiazepine use, so careful management in these groups is required

Avaliação de traços de personalidade em pacientes com fobia social

BACKGROUND: The symptoms of personality disorders (Axis II) commonly found in social phobia patients overlap highly with the symptoms that typify the Axis I disorder and are thus linked to diagnostic process in symptomatic patients. OBJECTIVE: The aim of the present study was to evaluate personality traits of social phobia patients. METHOD: One hundred and eight subjects were selected, from 18 to 65 years of age, who fulfilled the criteria of social phobia. The Cloninger's Temperament and Character Inventory (TCI) was applied. RESULTS: Social phobia patients differed in normalized data in the following personality traits: Novelty Seeking, Harm Avoidance, Persistence, Self Directedness, and Self-Transcendence. DISCUSSION: These findings point to a high overlap between Cloninger's description of the observed predominant personality traits and DSM-IV Axis I symptoms description for social phobia.CONTEXTO: Os sintomas de transtornos de personalidade (Eixo II) comumente encontrados em pacientes com fobia social se sobrepõem com os sintomas que descrevem o transtorno pelo Eixo I. OBJETIVO: O presente estudo teve por objetivo avaliar traços de personalidade em pacientes com diagnóstico de fobia social. MÉTODO: Cento e oito sujeitos com idade entre 18 e 65 anos foram avaliados pelo Inventário de Temperamento e Caráter de Cloninger. RESULTADO: Os pacientes com fobia social diferiram dos dados normativos nos seguintes traços de personalidade: Busca à Novidade, Fuga de Danos, Persistência, Autodirecionamento e Autotranscendência. CONCLUSÃO: Esses achados apontam para uma sobreposição entre a descrição dos traços de personalidade citados por Cloninger e a descrição dos sintomas de fobia social do DSM-IV, Eixo I

Primary headaches in patients with generalized anxiety disorder

Although anxiety disorders and headaches are comorbid conditions, there have been no studies evaluating the prevalence of primary headaches in patients with generalized anxiety disorder (GAD). The aim of this study was to analyze the lifetime prevalence of primary headaches in individuals with and without GAD. A total of 60 individuals were evaluated: 30 GAD patients and 30 controls without mental disorders. Psychiatric assessments and primary headache diagnoses were made using structured interviews. Among the GAD patients, the most common diagnosis was migraine, which was significantly more prevalent among the GAD patients than among the controls, as were episodic migraine, chronic daily headache and aura. Tension-type headache was equally common in both groups. Primary headaches in general were significantly more common and more severe in GAD patients than in controls. In anxiety disorder patients, particularly those with GAD, accurate diagnosis of primary headache can improve patient management and clinical outcomes
