The objective of the present study was to translate, adapt and validate a Brazilian Portuguese version of the Disabilities of the Arm, Shoulder and Hand (DASH) Questionnaire. The study was carried out in two steps. The first was to translate the DASH into Portuguese and to perform cultural adaptation and the second involved the determination of the reliability and validity of the DASH for the Brazilian population. For this purpose, 65 rheumatoid arthritis patients of either sex (according to the classification criteria of the American College of Rheumatology), ranging in age from 18 to 60 years and presenting no other diseases involving the upper limbs, were interviewed. The patients were selected consecutively at the rheumatology outpatient clinic of UNIFESP. The following results were obtained: in the first step (translation and cultural adaptation), all patients answered the questions. In the second step, Spearman's correlation coefficients for interobserver evaluation ranged from 0.762 to 0.995, values considered to be highly reliable. In addition, intraclass correlation coefficients ranged from 0.97 to 0.99, also highly reliable values. Spearman's correlation coefficients and the intraclass correlation coefficients obtained during intra-observer evaluation ranged from 0.731 to 0.937 and from 0.90 to 0.96, respectively, being highly reliable values. The Ritchie Index showed a weak correlation with Brazilian DASH scores, while the visual analog scale of pain showed a good correlation with DASH score. We conclude that the Portuguese version of the DASH is a reliable instrument.

A osteoporose é uma doença caracterizada por baixa massa óssea e deterioração da microarquitetura do tecido ósseo, com conseqüente aumento da fragilidade óssea e suscetibilidade a fraturas . Os recursos utilizados no tratamento de fraturas por osteoporose são siginificativos e com custos elevados. OBJETIVO: Dimensionar a utilização de recursos e custo anual por pacientes com osteoporose pós-menopausa. MÉTODOS: Cem pacientes foram consecutivamente selecionados do ambulatório de doenças osteometabólicas da Universidade Federal de São Paulo-Escola Paulista de Medicina (UNIFESP-EPM), entre abril de 1997 a agosto de 1998. Os critérios de inclusão foram: osteoporose pós-menopausa (OMS, 1994) há pelo menos um ano; mínimo de um ano em acompanhamento ambulatorial; mínimas condições de entendimento e expressão verbal para responder aos questionários. Características socio-econômicas, clínicas, utilização de recursos e custos no último ano foram levantadas através de entrevistas empregando-se dois questionários. Os custos unitários dos recursos utilizados no Serviço Público de Assistência à Saúde basearam-se na Tabela SUS de agosto de 1998. RESULTADOS: A média de idade foi 65,85 anos e a renda familiar média-mensal, R$ 534,14. Foram realizadas em média sete consultas/paciente/ano. Das pacientes, 77% usaram cálcio e 38% estrógenos por algum período durante o último ano. Os custos médios totais anuais para o tratamento das pacientes com osteoporose pós-menopausa, sob a perspectiva da sociedade, no Sistema Público em São Paulo, foram de R$ 908,18/paciente/ano. CONCLUSÃO: Os custos com o tratamento de osteoporose pagos pelas pacientes representaram 11% da renda familiar mensal média (R$ 534). Em função do envelhecimento da população e aumento da incidência de osteoporose, políticas de alocação racional de recursos basedas em análises econômicas devem ser implementadas.

BACKGROUND: Osteoporosis is characterized by low bone mass, deterioration of the microarchitecture of the bone tissue and increase susceptibility to fractures. Clinical manifestations are fractures and their complications. The most common fractures are hip,spine and wrist, although any bone is susceptible. OBJECTIVES: To assess the resource utilization and the annual costs incurred by patients with postmenopausal osteoporosis METHODS: One hundred consecutive patients were studied in the Universidade Federal de São Paulo. The inclusion criteria were: postmenopausal osteoporosis (WHO 1994) for at least one year b) at least one year attending the outpatient clinic, minimal comprehensive and speaking conditions.The socioeconomic and clinical characteristics, the resource utilization and costs in the last year were assessed using 2 questionnaires. The unitary costs were based in the Public Healthcare System Index (1998). RESULTS:The mean age was 66 years and the monthly family income was R$ 534.14 (US$ 456 -<FONT FACE=Symbol></FONT>in 1998). There was a mean of 7 visits/patient/ year. 77% of the patients used calcium and 38% used estrogens. The mean total annual costs for osteoporosis treatment, considering societal perspective, were R$ 908.18 (US$ 776-in 1998) per patient per year. CONCLUSION: The costs related to osteoporosis treatment represented 11% of the mean monthly household income from the patients' perspective (R$ 534=US$ 456). As the population is ageing and the osteoporosis incidence is increasing, health policy should be implemented to rationally allocate the scarce resources available, based on economic analysis.

The authors performed a study of bone mass in eutrophic Brazilian children and adolescents using dual-energy X-ray absorptiometry (DXA) in order to obtain curves for bone mineral content (BMC) and bone mineral density (BMD) by chronological age and correlate these values with weight and height. Healthy Caucasian children and adolescents, 120 boys and 135 girls, 6 to 14 years of age, residents of São Paulo, Brazil, were selected from the Pediatric Department outpatient clinic of Hospital São Paulo (Universidade Federal de São Paulo). BMC, BMD and the area of the vertebral body of the L2-L4 segment were obtained by DXA. BMC and BMD for the lumbar spine (L2-L4) presented a progressive increase between 6 and 14 years of age in both sexes, with a distribution that fitted an exponential curve. We identified an increase of mineral content in female patients older than 11 years which was maintained until 13 years of age, when a new decrease in the velocity of bone mineralization occurred. Male patients presented a period of accelerated bone mass gain after 11 years of age that was maintained until 14 years of age. At 14 years of age the mean BMD values for boys and girls were 0.984 and 1.017 g/cm², respectively. A stepwise multiple regression analysis of paired variables showed that the "vertebral area-age" pair was the most significant in the determination of BMD values and the introduction of a third variable (weight or height) did not significantly increase the correlation coefficient.

The purpose of the present study was to translate the Roland-Morris (RM) questionnaire into Brazilian-Portuguese and adapt and validate it. First 3 English teachers independently translated the original questionnaire into Brazilian-Portuguese and a consensus version was generated. Later, 3 other translators, blind to the original questionnaire, performed a back translation. This version was then compared with the original English questionnaire. Discrepancies were discussed and solved by a panel of 3 rheumatologists and the final Brazilian version was established (Brazil-RM). This version was then pretested on 30 chronic low back pain patients consecutively selected from the spine disorders outpatient clinic. In addition to the traditional clinical outcome measures, the Brazil-RM, a 6-point pain scale (from no pain to unbearable pain), and its numerical pain rating scale (PS) (0 to 5) and a visual analog scale (VAS) (0 to 10) were administered twice by one interviewer (1 week apart) and once by one independent interviewer. Spearman's correlation coefficient (SCC) and intraclass correlation coefficient (ICC) were computed to assess test-retest and interobserver reliability. Cross-sectional construct validity was evaluated using the SCC. In the pretesting session, all questions were well understood by the patients. The mean time of questionnaire administration was 4 min and 53 s. The SCC and ICC were 0.88 (P<0.01) and 0.94, respectively, for the test-retest reliability and 0.86 (P<0.01) and 0.95, respectively, for interobserver reliability. The correlation coefficient was 0.80 (P<0.01) between the PS and Brazil-RM score and 0.79 (P<0.01) between the VAS and Brazil-RM score. We conclude that the Brazil-RM was successfully translated and adapted for application to Brazilian patients, with satisfactory reliability and cross-sectional construct validity.

Heart transplantation is associated with rapid bone loss and an increased prevalence and incidence of fractures. The aim of the present study was to compare the bone mineral density (BMD) of 30 heart transplant (HT) recipients to that of 31 chronic heart failure (CHF) patients waiting for transplantation and to determine their biochemical markers of bone resorption and hormone levels. The BMD of lumbar spine and proximal femur was determined by dual-energy X-ray absorptiometry. Anteroposterior and lateral radiographs of the thoracic and lumbar spine were also obtained. The mean age of the two groups did not differ significantly. Mean time of transplantation was 25.4 ± 21.1 months (6 to 88 months). Except for the albumin levels, which were significantly higher, and magnesium levels, which were significantly lower in HT patients when compared to CHF patients, all other biochemical parameters and hormone levels were within the normal range and similar in the two groups. Both groups had lower BMD of the spine and proximal femur compared to young healthy adults. However, the mean BMD of HT patients was significantly lower than in CHF patients at all sites studied. Bone mass did not correlate with time after transplantation or cumulative dose of cyclosporine A. There was a negative correlation between BMD and the cumulative dose of prednisone. These data suggest that bone loss occurs in HT patients mainly due to the use of corticosteroids and that in 30% of the patients it can be present before transplantation. It seems that cyclosporine A may also play a role in this loss.
