Reliability of a questionnaire for diagnosing the severity of temporomandibular disorder
CONTEXTUALIZAÇÃO: Disfunção temporomandibular (DTM) é um termo coletivo que engloba vários problemas clínicos envolvendo a musculatura da mastigação, as articulações temporomandibulares (ATM) e suas estruturas associadas, com alta prevalência nas populações. OBJETIVOS: Sabendo-se que estudos brasileiros vêm utilizando o instrumento proposto por Da Fonseca et al. (1994) para diagnóstico da severidade desta disfunção, realizou-se este estudo com o objetivo de verificar e estimar a consistência interna e a reprodutibilidade do mesmo. MÉTODOS: O delineamento amostral adotado foi o probabilístico, e participaram 1230 indivíduos moradores da cidade de Ribeirão Preto (SP), maiores de 18 anos de idade. As entrevistas foram realizadas por um único entrevistador por meio de ligações telefônicas. Para estudo da consistência interna, calculou-se o Coeficiente de Kuder-Richardson (kr-20) e para estimar a reprodutibilidade, utilizou-se a estatística Kappa (κ). RESULTADOS: A consistência interna do formulário foi de 0,5594, apontando para uma validação abaixo do desejado. Observou-se maior contribuição das questões 1, 2, 3, 6 e 7 para o coeficiente kr-20 total e maior consistência do instrumento quando composto apenas pelas mesmas (0,7044). Observou-se reprodutibilidade "Boa" e "Ótima" para as questões. CONCLUSÕES: Frente ao exposto, sugere-se que o formulário proposto por Da Fonseca et al. (1994) seja adaptado, ficando composto apenas pelas questões 1, 2, 3, 6 e 7 da versão inicial, colaborando, assim, para aumento da confiabilidade do instrumento. Deve-se ressaltar ainda a necessidade da realização de estudos de validade para assegurar adequadas características psicométricas à nova versão do instrumento.BACKGROUND: Temporomandibular disorder (TMD) is a collective term that encompasses many clinical problems involving the masticatory muscles, temporomandibular joints (TMJ) and associated structures and it has high prevalence among populations. OBJECTIVES: Because Brazilian studies have used the instrument proposed by Da Fonseca et al. (1994) to diagnose the severity of TMD, this study was conducted to investigate and estimate the internal consistency and reproducibility of this method. METHODS: We used a probability sampling design to select 1230 participants over the age of 18 years who were living in the city of Ribeirão Preto, SP, Brazil. The interviews were conducted by a single interviewer over the phone. The internal consistency was analyzed by calculating the Kuder-Richardson coefficient (kr-20), and kappa statistics (κ) were used to estimate the reproducibility. RESULTS: The internal consistency of the questionnaire was 0.5594, thus indicating that validation was lower than desired. Questions 1, 2, 3, 6 and 7 had greater contribution towards the total kr-20 coefficient, and the consistency of the instrument was higher when it was composed only of these questions (0.7044). "Good" and "Excellent" reproducibility was observed for these same questions. CONCLUSIONS: Based on these data, it is suggested that the questionnaire proposed by Da Fonseca et al. (1994) should be adapted to include only questions 1, 2, 3, 6 and 7 of the initial version. This would help improve the reliability of the instrument. The need for validation studies must also be emphasized to ensure that the new version of the instrument has adequate psychometric characteristics

Acetazolamide for the prophylaxis of migraine in CADASIL: a preliminary experience
Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an inherited microangiopathy caused by NOTCH3 mutations. It is characterized by migraine, with or without aura, ischemic events, psychiatric and cognitive disturbances. There is no approved treatment for migraine prophylaxis in CADASIL, but acetazolamide has been anecdotally reported to be effective. We retrospectively reviewed our database of patients with a genetic diagnosis of CADASIL to identify how many of them were treated with acetazolamide for the prophylaxis of migraine. The efficacy and the tolerability of this treatment were checked looking at the clinic reports. Acetazolamide was prescribed in seven patients; the mean duration of treatment was 6 months, and the daily dose ranged from 125 to 500 mg. Three patients had a total and sustained remission, while in two patients a reduction in attacks and an improvement of the headache intensity were recorded. In one of these, acetazolamide was deliberately taken only during the migraine attack and the beneficial effect started 1 h after administration. In two patients, the drug did not produce any beneficial effect. Mild side effects were recorded in two patients. Our preliminary experience expands previous reports and confirms the possible efficacy of acetazolamide in CADASIL migraine. Based on these data, a randomized controlled trial seems worthy to be carried out to test the efficacy and safety of this drug

Prevalence and costs of headaches for the public health system in a town in the interior of the state of São Paulo Prevalência e custos das cefaléias para o Sistema Público de Saúde de uma cidade do interior do Estado de São Paulo
Despite the high prevalence, impact and economic importance of headaches, studies on this subject are rare in Brazil. The aim of the present study was to estimate the prevalence of headaches in the public health system of a town in the interior of the State of São Paulo, as well as to estimate the costs resulting from its management. Data refer to the year of 1998 and were obtained according to the following steps: 1) territorial and demographic characterization of the municipality; 2) characterization of the financial indices and social well-being; 3) budget characteristics of the municipality; 4) evaluation of the structuring of the medical service; 5) determination of the prevalence of headaches at different patient care levels; and 6) calculation of the costs of headaches. Headaches represented 7.9% of all visits at basic health units, 9.7% in the emergency room and 1.1% of hospital admissions. The total costs were R 70,942.76) corresponding to R 6,32) per inhabitant/year. The present study shows the need for epidemiological and economic impact studies, which would provide the basis for the rational use of health funds.<br>Apesar da grande prevalência, impacto e importância econômica das cefaléias, são incomuns os estudos referentes a esses aspectos em nosso meio. O presente estudo visa estimar a prevalência das cefaléias no sistema público de uma cidade do interior do Estado de São Paulo, bem como estimar os custos decorrentes de seu manejo. Os dados referem-se ao ano de 1998 e obedeceram às seguintes etapas: 1 -- caracterização territorial e demográfica do município; 2 -- caracterização de índices financeiros e de bem estar social; 3 -- características orçamentárias do município; 4 -- avaliação da estruturação do atendimento médico; 5 -- levantamento da prevalência das cefaléias nos diversos níveis de atendimento; 6 -- cálculo dos custos das cefaléias. Cefaléias foram responsáveis por 7,9% dos atendimentos em unidades básicas de saúde, 9,7% em pronto socorro e 1,1% das internações hospitalares. Os custos totais foram de R 70,942.76) o que equivale a R 6,32) por habitante/ano. Esse estudo demonstra a necessidade da realização de trabalhos epidemiológicos e de impacto econômico que permitam racionalizar o emprego de verbas para a saúde
