OBJETIVO: Avaliar o efeito da corrente catódica de alta voltagem sobre a dor em um modelo experimental de ciatalgia. MÉTODOS: Foram utilizados 16 ratos Wistar, machos, submetidos a um modelo de ciatalgia experimental no membro pélvico direito. Os sujeitos foram divididos em grupo simulacro (GS) e grupo tratado com corrente catódica (GP-) por 20 min diários durante 10 dias. O modelo de compressão foi realizado com amarria por fio catgut 4.0 cromado, em quatro pontos ao longo do nervo isquiático. A avaliação da nocicepção foi realizada, de forma funcional, com o tempo de elevação da pata (TEP), e à pressão, pelo limiar de retirada, via analgesímetro eletrônico. Os dados foram coletados antes do modelo de ciatalgia (AV1), três dias depois da compressão (antes, AV2, e após o tratamento, AV3), após o quinto dia de tratamento (AV4) e em seguida ao décimo dia de tratamento (AV5). RESULTADOS: Pela avaliação funcional, em ambos os grupos houve aumento da nocicepção, sem redução da mesma em qualquer momento da avaliação. À pressão, no entanto, o GS mostrou redução do limiar de retirada em todos os momentos, enquanto o GP- apresentou redução do limiar apenas inicialmente - em AV5 o limiar foi restaurado. CONCLUSÃO: Não houve alteração na nocicepção pela avaliação funcional; porém, à pressão, o tratamento com corrente catódica mostrou efeito com a somatória de terapias.

OBJETIVO: Avaliar a ação precoce do laser terapêutico e do ultrassom no processo de regeneração de uma lesão experimental em ratos. MÉTODO: Utilizou-se 24 ratos. Dezoito foram submetidos ao procedimento cirúrgico de lesão do nervo ciático por compressão, através de uma pinça hemostática acima da fossa poplítea. Os animais foram divididos em três grupos com seis animais em cada. Grupo controle normal. GI: controle lesado sem intervenção terapêutica. GII: intervenção terapêutica do laser ArGaAl. GIII: intervenção terapêutica do ultrassom Pulsado. Iniciamos as intervenções terapêuticas 24 horas após a lesão, com aplicações diárias, por um período de quatorze dias consecutivos. RESULTADOS: Ao avaliar a perimetria dos músculos da coxa direita obteve-se os seguintes valores médios de diminuição (mm), para cada grupo GI: 0,45; GII: 0,42; GIII: 0,40. Quanto ao tempo de deslocamento tanto o GII e GIII apresentaram diferença significativa, quando comparados ao GI. Na avaliação final do IFC o GII sobressaiu ao GIII. Quanto a cicatrização observou-se grande melhora no GII e GIII. CONCLUSÃO: Os resultados evidenciaram que a recuperação nervosa foi maior com a aplicação do laser.

A base do tratamento cirúrgico da Síndrome do Desfiladeiro Torácico (SDT) é a ressecção da primeira costela, podendo associar-se à escalenectomia ou ainda à ressecção de costela cervical. Esta última é feita tradicionalmente por meio de um acesso supraclavicular ou mesmo axilar, o qual é tecnicamente mais trabalhoso. Pode ser realizada também por meio de acesso paraescapular. Embora tecnicamente atrativa e associada à menor invasividade e maior segurança, com ótimo resultado estético, a ressecção da primeira costela torácica, por intermédio de cirurgia videoassistida transaxilar ou pela técnica videotoracoscópica, é pouco relatada na literatura, e nenhuma referência foi encontrada sobre ressecção de costela cervical mediante essa técnica. Neste artigo, apresentamos essa inovação cirúrgica realizada com sucesso para ressecção de costela cervical em duas pacientes.

This paper looks at the severe fasting practices most commonly found among young women. Almost all explanations for this behaviour centre around the notion of the pathological condition 'anorexia nervosa'. However, food asceticism has a well-documented history, particularly when it concerns religious fasting. In ancient Greece, dietary asceticism constituted an important part of the means by which individuals constructed an acceptable 'self'. Ascetic fasting then later resurfaced at various historical moments and in various different places — such as amongst medieval religious women and, in a broader way, amongst contemporary young women. It is argued that these practices have traditionally formed part of the mechanisms by which differentiation by age and sex occurs. Overall, it is hoped that this analysis will permit not only a different focus on 'anorexia nervosa', but also on some of the ways in which young people become gendered.

As with the ancient Greeks, the `self' is not something to be discovered, it is something to be created. Practices such as ascetic fasting are not expressions of the struggle between the authentic self and the external world, they are the very practices by which a `self' is formed.

INTRODUCTION: Anorexia nervosa (AN) is a growing problem among young female Singaporeans. We studied the demographics and follow-up data of AN patients referred to dietitians for nutritional intervention. METHODS: A retrospective nutritional notes review was done on 94 patients seen from 1992 to 2004. All patients were given nutritional intervention, which included individualised counselling for weight gain, personalised diet plan, correction of poor dietary intake and correction of perception towards healthy eating. We collected data on body mass index (BMI), patient demographics and outcome. RESULTS: 96 percent of the patients were female and 86.2 percent were Chinese. The median BMI at initial consultation was 14.7 kilogramme per square metre (range, 8.6-18.8 kilogramme per square metre). 76 percent were between 13 and 20 years old. 83 percent of the patients came back for follow-up appointments with the dietitians in addition to consultation with the psychiatrist. Overall, there was significant improvement in weight and BMI from an average 37 kg to 41 kg and 14.7 kilogramme per square metre to 16.4 kilogramme per square metre, respectively, between the fi rst and fi nal consultations (p-value is less than 0.001). The average duration of followup was about eight months. Among the patients on follow-up, 68 percent showed improvement with an average weight gain of 6 kg. Patients that improved had more outpatient follow-up sessions with the dietitians (4.2 consultations versus 1.6 consultations; p-value is less than 0.05), lower BMI at presentation (14.2 kilogramme per square metre versus 15.7 kilogramme per square metre; p-value is less than 0.01) and shorter duration of disease at presentation (one year versus three years; p-value is less than 0.05) compared with those who did not improve. Seven patients with the disease for more than two years did not show improvement with follow-up. CONCLUSION: We gained valuable understanding of the AN patients referred to our tertiary hospital for treatment, two-thirds of whom improved with adequate follow-up treatment. Patients that had suffered AN longer before seeking help appeared more resistant to improvement.

Previous studies on lay theories of anorexia nervosa have examined the 'accuracy' of lay knowledge, and the identification of factors by family and friends that would encourage early interventions. In contrast to these approaches, we examine lay theories of anorexia nervosa using a critical psychology perspective. We argue that the use of a discourse analysis methodology enables the examination of the construction of lay theories through dominant concepts and ideas. Ten semi-structured interviews with five women and five men aged between 15 and 25 years were carried out. Participants were asked questions about three main aspects of anorexia nervosa: aetiology, treatment and relationship to gender. Each interview was analysed in terms of the structure, function and variability of discourse. Three discourses: sociocultural, individual and femininity, are discussed in relation to the interview questions. We conclude that, in this study, lay theories of anorexia nervosa were structured through key discourses that maintained a separation between sociocultural aspects of anorexia nervosa and individual psychology. This separation exists in dominant psychomedical conceptualizations of anorexia nervosa, reinforcing the concept that it is a form of psychopathology.

The purpose of this study was to examine how men account for the diagnosis in men of anorexia nervosa (AN), a condition commonly associated with women. Male students participated in focus group discussions of topics related to AN. Discussions were tape-recorded with participants' consent, transcribed, and then analyzed using discourse analysis. The participants spontaneously constructed AN as a female-specific condition. When asked to account for AN in men, they distanced AN from hegemonic masculinities in ways that sustained both dominant masculine identities and gender-specific constructions of AN. These findings show how issues of health and gender are interlinked in everyday understandings of AN. Future researchers might usefully consider how the construction of gender-specific illness implicates wider notions of both feminine and masculine gender identities.

It is always difficult to know what reviewers such as Colin Holmes (2001) want from a book. While he knows something of the claims that Gull was thought by some to be Jack the Ripper – an historical digression deliberately omitted from the book – Holmes has, it would seem, little understanding of the practice implications of Foucauldian analysis...

"In this wide-ranging book, Julie Hepworth casts a critical light on our contemporary understanding of anorexia nervosa. She locates contemporary discourses of anorexia nervosa within their historical context, showing how current practices continue to be influenced by medicine, psychology, ideology and politics. She argues that anorexia nervosa must be considered within the political, social and gendered relationships that continue to contribute to its definition. The book demonstrates the need for a new conceptualization of anorexia nervosa which would draw on the insights of discourse theory, feminism and postmodernism to create new understandings of anorexia nervosa within contemporary health care practices." -- publisher website

Previous studies on lay theories of anorexia nervosa have examined the ‘accuracy’ of lay knowledge, and the identification of factors by family and friends that would encourage early interventions (Huon, Brown, & Morris, 1988, 7, 239–252; Murray, Touyz, & Beumont, 1990, 9, 87–93). In contrast to these approaches, we examine lay theories of anorexia nervosa using a critical psychology perspective. We argue that the use of a discourse analysis methodology enables the examination of the construction of lay theories through dominant concepts and ideas. Ten semi-structured interviews with five women and five men aged between 15 and 25 years were carried out. Participants were asked questions about three main aspects of anorexia nervosa: aetiology, treatment and relationship to gender. Each interview was analysed in terms of the structure, function and variability of discourse. Three discourses: sociocultural, individual and femininity, are discussed in relation to the interview questions. We conclude that, in this study, lay theories of anorexia nervosa were structured through key discourses that maintained a separation between sociocultural aspects of anorexia nervosa and individual psychology. This separation exists in dominant psychomedical conceptualizations of anorexia nervosa, reinforcing the concept that it is a form of psychopathology.
