Obsessive-compulsive symptoms in patients with panic disorder

Comorbidity studies have shown an important association between panic disorder (PD) and obsessive-compulsive disorder (OCD). The aim of the current study was to evaluate the prevalence of obsessive-compulsive symptoms (OCS) and OCD in patients with PD. Forty-eight consecutive PD cases (DSM-IV diagnostic criteria) referred to a Brazilian university hospital clinic were studied. The Yale Brown Obsessive Compulsive scale (Y-BOCS) checklist was used to identify the OCS. Subclinical OCD was considered when subjects met all but one DSM-IV criteria for OCD (symptoms did not cause significant distress and interference, did not last more than 1 hour per day, or were not considered excessive or irrational), and OCS when only the criterion for presence of obsessions or compulsions was met. Twenty-nine (60.4%) of the 48 patients evaluated (19 men and 29 women) had at least one OCS: nine (18.8%) had mild OCS, 11 (22.9%) had subclinical OCD, and nine (18.8%) had comorbid OCD. Therefore, 41.7% of the patients had either clinical or subclinical OCD. OCS occurred more frequently in women and, in 70.4% of the cases, preceded the onset of PD. Our results suggest that it is important to evaluate systematically the co-occurrence of OCS in patients with PD, due to the considerable overlap found in symptoms, which may have therapeutic implications. As panic symptoms are usually the main complaint, OCS are often found only when directly investigated. (C) 2004 Elsevier B.V. All rights reserved.

Raciocínio moral na tomada de decisões em relação a questões sociocientíficas: o exemplo do melhoramento genético humano

Nos últimos anos, os avanços nas Ciências Biológicas têm levado a sociedade a discutir diversas questões no campo da moral e da ética. Questões como engenharia genética, clonagem e pesquisas com células-tronco são questões chamadas de sociocientíficas por estarem na interface entre a ciência e a sociedade. Nesse trabalho buscamos entender como estudantes de Ensino Médio percebem e interpretam questões relacionadas à manipulação genética em seres humanos. Houve divisão de opiniões em relação à eugenia negativa, que se destina a remover características desfavoráveis das pessoas; mas a eugenia positiva, que busca melhoramento de características estéticas, foi rejeitada por todos os estudantes. As variações nas opiniões em relação ao assunto tratado podem ser, em grande medida, devidas às representações sociais dos estudantes.

Fighting by sleep-deprived rats as a possible manifestation of panic: effects of sodium lactate

Increased fighting is an effect of desynchronized sleep deprivation (DSD) in rats, and recently this behavior has been suggested to be spontaneous panic and equivalent to panic disorder. In the present study we tested this hypothesis by evaluating the effect of sodium lactate on this aggressiveness, because this substance is recognized to induce spontaneous panic attacks in patients. A total of 186 male albino Wistar rats, 250-350 g, 90-120 days of age, were submitted to DSD (multiple platform method) for 0, 4, or 5 days. At the end of the deprivation period the rats were divided into subgroups respectively injected intraperitoneally with 1.86, 2.98 and 3.72 g/kg of 1 M sodium lactate, or 1.86 and 3.72 g/kg of 2 M sodium lactate. The control animals were submitted to the same procedures but received equivalent injections of sodium chloride. Regardless of DSD time, sleep-deprived animals that received sodium lactate presented a significantly higher mean number of fights (0.13 ± 0.02 fights/min) and a longer mean time spent in confrontation (2.43 ± 0.66 s/min) than the controls (0.01 ± 0.006 fights/min and 0.12 ± 0.07 s/min, respectively; P<0.01, Student t-test). For the sodium lactate group, concentration of the solution and time of deprivation increased the number of fights, with the mean number of fights and mean duration of fighting episodes being greater with the 2.98 g/kg dose using 1 M lactate concentration. These results support the hypothesis that fighting induced by DSD is probably a spontaneous panic manifestation. However, additional investigations are necessary in order to accept this as a promising animal model for studies on panic disorder.

Ética e moral como modos de produção de subjetividade

Deleuze e Guattari entendem as idéias de Ética e Moral como movimentos produtores de realidade psicossocial ou sentidos de produção da vida psicossocial. Buscamos entender como os modos de funcionamento psicossociais produzem sentidos e podem ser captados nas práticas psicossociais éticas e morais. Nossa intenção é demonstrar, a partir da literatura kafkiana, os modos de subjetivação ética e moral.

A formação de personalidades éticas: representações de si e moral

O artigo apresenta os estudos de uma investigação atual entre 75 adolescentes de 12 a 15 anos, estudantes de colégios particulares da cidade de Campinas, que tem como principal objetivo constatar a possível correspondência entre os julgamentos morais e as representações que os sujeitos têm de si mesmos. A partir de um questionário, os estudos destacam as representações desses sujeitos e respondem a um questionamento de que teriam um caráter ético ou não e se corresponderiam a seus julgamentos morais. Os resultados apontam para uma correspondência entre aqueles cujas representações de si são caracterizadas por conteúdos éticos e julgamentos mais evoluídos quanto à sensibilidade aos sentimentos dos personagens envolvidos nas situações descritas. Tais estudos validam a intenção deste artigo de discutir as correspondências entre ética (como o sujeito se vê) e moral (como julga as situações morais).

Potentiation of panic-like behaviors of the rat by subconvulsive doses of strychnine

The present study was carried out to determine possible panicogenic effects of strychnine administered in subconvulsive doses to rats. Two experiments were conducted to assess two major features of panic in animal models: panic-related flight (through the observation of wild running [WR]) and defensive fights. In the first one, 20 adult male Wistar rats were injected with six different doses of strychnine ranging from 0.5 to 4.0 mg/kg. After 15 min of free observation, the animals were submitted to high-intensity acoustic stimulation and the incidence of WR was recorded. Higher doses of strychnine (above 2.5 mg/kg) easily evoked seizures, but lower doses raised the incidence of WR in a dose-dependent manner. The most effective dose for WR (1.5 mg/kg) was used in the second experiment, in which we investigated the effects of strychnine on sleep-deprivation-induced fights (SDIFs) that have defensive characteristics. For this purpose, 40 subjects were submitted to 5 days of REM-sleep deprivation by the single-platform method and were then assigned into two groups, i.e., strychnine vs. control. After the injections, the animals were observed in social groupings for SDIF recordings over a period of 60 min. The strychnine-treated groups had more SDIF than the control groups (P<.05, Mann-Whitney U test). We conclude that the high level of neural excitability promoted by partial blockade of the glycinergic system can contribute to the manifestation of panic reactions. (C) 2003 Elsevier B.V.

A validação do Teste de Juízo Moral (MJT) para diferentes culturas: o caso brasileiro

The present article deals with the adaptation of the Moral Judgment Test (MJT) for the Portuguese language. The principles of the test, its format and the process of content, construct and criterion validation are presented. In the same way, reliability is discussed using Brazilian research results that produced the necessity of elaborating another dilemma to compose the MJT-xt (extended).

B. F. Skinner: Teórico da ciência e teórico da moral?

Would Skinner's moral theory be dependent on his scientific theory to the point of becoming meaningless without it? The mere suggestion of such hypothesis brings the problem of naturalistic fallacy, that is, the problem of deriving statements of ought kind from statements of is kind. This issue is used here as an indication that suggests how problematic sustaining a moral and a scientific theory in the same ambit can be. The aim of this article, in this context, is to analyze if that is the case of Radical Behaviorism. Inspired by the naturalistic fallacy dilemma, the first step is to expose the structural and functional differences between statements of ought kind and statements of is kind. To do so, the strategy is to present, under the scope of language philosophy, the differences between factual and valuative assertions. The next step consists in analyzing what the nature of relations between Skinner's scientific and moral theories is. That is, if there are necessary or contingencial relations. By doing so it is expected to be plausible the presentation of a possible answer to the central question of this article.

Moral judgment competence of medical students: a transcultural study

The authors conducted a cross-sectional short-term study using Lind's Moral Judgment Test (MJT) to compare moral judgment competence (C-score) among students from a medical school in the Northeast region of Brazil and a medical school in the Northern region of Portugal. This study compares the C-scores of groups in the first and eighth semesters of study within each medical school and groups from corresponding semesters between the two medical schools. This study also evaluates the influence of such factors as age and gender on moral competence. A regression of moral judgment competence among the students in their eighth semester versus the students in the first semester of Brazilian medical school (p < 0.001) and a stagnation of moral competence among students in their eighth semester versus the first semester students in the Portuguese medical school (p = 0.06) were observed. For both the first semester and eighth semester groups, the students in the Portuguese medical school had higher C-scores than the students in the Brazilian medical school. In the analysis of the students' performances in terms of MJT dilemmas, the phenomenon of moral segmentation was observed in all of the groups, and the students performed better on the worker's dilemma than on the doctor's dilemma. Among students in the same semester of study, older students had lower C-scores. There was generally no significant difference between men's and women's C-scores. © 2013 Springer Science+Business Media Dordrecht.
