Relationship of cryptosporidiosis to abdominal pain and diarrhea in Mayan Indians

Demonstration of cryptosporidiosis in Mayan Indians living around Lake Atitlan provided an opportunity to correlate infection with abdominal pain and/or diarrhea in different age groups of children. 94 subjects experiencing abdominal pain and/or diarrhea, between the ages of 2 and 13 were studied in towns around Lake Atitlan, Guatemala, over a two-year period. Cryptosporidium oocysts were found in the feces of 29% of children who presented with abdominal pain and 21% with diarrhea. Of the 60 infected subjects, 45% were experiencing abdominal pain and 33% diarrhea, 22% had abdominal pain and diarrhea. Both abdominal pain and diarrhea were significantly higher in children under 10 years of age and were most prevalent in the 6-9 year old age group but the correlation of symptoms to infection was not significantly different as the ages of the children increased. The high frequency of abdominal pain and/or diarrhea with infection in children was consistent with cryptosporidiosis, a disease considered as one of several common intestinal infections that produce these symptoms.

Wii-Workouts on Chronic Pain, Physical Capabilities and Mood of Older Women: A Randomized Controlled Double Blind Trial

Chronic Low Back Pain (CLBP) is a public health problem and older women have higher incidence of this symptom, which affect body balance, functional capacity and behavior. The purpose of this study was to verifying the effect of exercises with Nintendo Wii on CLBP, functional capacity and mood of elderly. Thirty older women (68 ± 4 years; 68 ± 12 kg; 154 ± 5 cm) with CLBP participated in this study. Elderly individuals were divided into a Control Exercise Group (n = 14) and an Experimental Wii Group (n = 16). Control Exercise Group did strength exercises and core training, while Experimental Wii Group did ones additionally to exercises with Wii. CLBP, balance, functional capacity and mood were assessed pre and post training by the numeric pain scale, Wii Balance Board, sit to stand test and Profile of Mood States, respectively. Training lasted eight weeks and sessions were performed three times weekly. MANOVA 2 x 2 showed no interaction on pain, siting, stand-up and mood (P = 0.53). However, there was significant difference within groups (P = 0.0001). ANOVA 2 x 2 showed no interaction for each variable (P > 0.05). However, there were significant differences within groups in these variables (P < 0.05). Tukey's post-hoc test showed significant difference in pain on both groups (P = 0.0001). Wilcoxon and Mann-Whitney tests identified no significant differences on balance (P > 0.01). Capacity to Sit improved only in Experimental Wii Group (P = 0.04). In conclusion, physical exercises with Nintendo Wii Fit Plus additional to strength and core training were effective only for sitting capacity, but effect size was small.

Exercise-Induced Intraventricular Obstruction in a Child with Near Syncope and Chest Pain During Exercise

We report the case of a 10-year-old girl with two episodes of light-headedness and chest pain during exercise. She had an unremarkable clinical record, physical examination, ECG, and echocardiogram. Noninvasive ischemia tests were positive, but coronary angiography was normal. Exercise stress echocardiogram revealed an exercise-induced intra-left-ventricular obstruction with a peak gradient of 78 mmHg and replicated her symptoms. After starting beta-blocker therapy her clinical status improved and no residual obstruction was detected. The authors review this unsuspected clinical condition, seldom reported in the adult population and, to our knowledge, never before in a child.

Thoracic Manifestations of Connective Tissue Diseases

Connective tissue diseases (CTDs) comprise several immunologic systemic disorders, each of which associated with a particular set of clinical manifestations and autoimmune profile. CTDs may cause numerous thoracic abnormalities, which vary in frequency and pattern according to the underlying disorder. The CTDs that most commonly involve the respiratory system are progressive systemic sclerosis, systemic lupus erythematosus, rheumatoid arthritis, Sjögren syndrome, polymyositis, dermatomyositis, and mixed connective tissue disease. Pulmonary abnormalities in this group of patients may result from CTD-related lung disease or treatment complications, namely drug toxicity and opportunistic infections. The most important thoracic manifestations of CTDs are interstitial lung disease and pulmonary arterial hypertension, with nonspecific interstitial pneumonia being the most common pattern of interstitial lung disease. High-resolution computed tomography is a valuable tool in the initial evaluation and follow-up of patients with CTDs. As such, general knowledge of the most common high-resolution computed tomographic features of CTD-related lung disease allows the radiologist to contribute to better patient management.

Women's Attachment as a Predictor of Pain During Labour and Post-Delivery: a Prospective Observational Study

INTRODUCTION: Labour is considered to be one of the most painful and significant experiences in a woman's life. The aim of this study was to examine whether women's attachment style is a predictor of the pain experienced throughout labour and post-delivery. MATERIAL AND METHODS:Thirty-two pregnant women were assessed during the third trimester of pregnancy and during labour. Adult attachment was assessed with the Adult Attachment Scale ' Revised. The perceived intensity of labour pain was measured using a visual analogue scale for pain in the early stage of labour, throughout labour and post-delivery. RESULTS:Women with an insecure attachment style reported more pain at 3 cm of cervical dilatation (p < 0.05), before the administration of analgesia (p < 0.01) and post-delivery (p < 0.05) than those securely attached. In multivariate models, attachment style was a significant predictor of labour pain at 3 cm of cervical dilatation and before the first administration of analgesia but not of the perceived pain post-delivery. DISCUSSION: These findings confirm that labour pain is influenced by relevant psychological factors and suggest that a woman's attachment style may be a risk factor for greater pain during labour. CONCLUSION:Future studies in the context of obstetric pain may consider the attachment style as an indicator of individual differences in the pain response during labour. This may have important implications in anaesthesiology and to promote a relevant shift in institutional practices and therapeutic procedures.

Contributo para a validação da versão portuguesa da Quebec Back Pain Disability Scale : fiabilidade e poder de resposta em utentes com dor lombar crónica

RESUMO: Um dos principais resultados das intervenções de Fisioterapia dirigidas a utentes com Dor Lombar Crónica (DLC) é reduzir a incapacidade funcional. A Quebec Back Pain Disability Scale (QBPDS) é um instrumento amplamente aceite a nível internacional na medição do nível de incapacidade funcional reportada pelos indivíduos com DLC. O objetivo deste estudo é dar um contributo para a adaptação cultural da versão portuguesa da QBPDS (QBPDS-VP) e investigar o poder de resposta e interpretabilidade da escala. Metodologia: Realizou-se um estudo metodológico, multicentro, baseado num coorte prospetivo de 132 utentes com DLC. Os utentes foram recrutados a partir da lista de espera de 16 serviços de Medicina Física e de Reabilitação/Fisioterapia de várias áreas geográficas de Portugal. A QBPDS- VP foi administrada 3 vezes, em 3 momentos de recolha de dados distintos: T0 - momento inicial (utentes em lista de espera); T1 - 1 semana de intervalo (início dos tratamentos de Fisioterapia); e T2 - 6 semanas de intervalo (pós-intervenção de Fisioterapia). Os dados recolhidos em T0 foram utilizados para a análise fatorial e para o estudo da consistência interna (n=132); os dados da amostra emparelhada de T0 e T1 (n=132) para a fiabilidade teste-reteste; e os dados da amostra emparelhada de T0 e T2 (n=120) para a análise do poder de resposta e interpretabilidade. A âncora externa utilizada foi a perceção global de mudança, neste caso a PGIC- VP, que foi respondida em T1 e T2. O nível de significância para o qual os valores se consideraram satisfatórios foi de p≤ 0,05. O tratamento dos dados foi realizado no software IBM SPSS Statistics (versão 20). Resultados: A QBPDS- VP é uma escala unidimensional, que revela uma excelente consistência interna (α de Cronbach= 0,95) e uma fiabilidade teste-reteste satisfatória (CCI= 0,696; IC 95%: 0,581–0,783). Esta escala demonstrou um poder de resposta moderado, quando aplicada em utentes com DLC ( = 0,426 e AAC= 0,741; IC 95%: 0,645 – 0,837). A Diferença Mínima Detetável (DMD) estimada foi de 19 pontos e as estimativas da Diferença Mínima Clinicamente Importante (DMCI) variaram entre 7 (pelo método curva ROC) e 8 pontos (pelo método “diferença média de pontuação”). A estimativa pela curva ROC deriva do ponto ótimo de corte de 6,5 pontos, com Área Abaixo da Curva (AAC)= 0,741, sensibilidade de 72%, e especificidade de 71%. Uma análise complementar da curva ROC baseada nas diferenças de pontuações da QBPDS, expressa em percentagem, revelou um ponto ótimo de corte de - 24% (AAC= 0,737, sensibilidade de 71%, e especificidade de 71%). Para pontuações iniciais da QBPDS- VP mais altas (≥34 pontos), foi encontrado um ponto ótimo de corte de 10,5 pontos (AAC= 0,738, sensibilidade de 73%, e especificidade de 67%). Conclusão: A QBPDS-VP demonstrou bons níveis de fiabilidade e poder de resposta, recomendando-se o seu uso na medição e avaliação da incapacidade funcional de utentes com DLC. A DMD estimada, de 19 pontos, determinou uma amplitude válida da QBPDS-VP de 19 a 81 pontos. Este estudo propõe estimativas de DMCI da QBPDS- VP numa aplicação específica da escala (em utentes com DLC que são referidos para a intervenção de Fisioterapia). A pontuação inicial da QBPDS- VP deve ser considerada na interpretação de mudanças de pontuação, após a intervenção de Fisioterapia.------------ ABSTRACT: One of the main results of physiotherapy interventions for patients with Chronic Low Back Pain (CLBP) is decrease the functional disability. The Quebec Back Pain Disability Scale (QBPDS) is an instrument widely accepted internationally, in measuring the level of disability reported by individuals with CLBP. The purpose of this study is to contribute to the cultural adaptation of the Portuguese version of QBPDS (QBPDS - PV) and investigate the Responsiveness and Interpretability of QBPDS-PV. Methodology: This was a methodological and multicenter study, based on a sample of 132 subjects with CLBP. The patients were recruited from the waiting lists of 16 medicine rehabilitation service, in many Portugal districts. The Quebec Back Pain Disability Scale was administered in three different moments: T0 – baseline (patients in the waiting list); T1- one week after T0 (the beginning of treatment); and T2 – six weeks after T1 (the posttreatment). The data collected at T0 were used for factor analysis and to study the internal consistency (n = 132); paired sample data of T0 and T1 (n=132) were used for test-retest reliability, and sample data paired for T0 and T2 (n=120) used for responsiveness and interpretability analysis. The external anchor was the global perception of change, measured by the Portuguese version of Patient’s Global Impression of Change (PGIC) Scale. The minimal level of significance established was p ≤ 0,05. Data analysis was performed using the IBM SPSS Statistics software (version 20). Results: The QBPDS-PV is a unidimensional scale, demonstrates an excellent internal consistency (Cronbach's α=0.95) and satisfactory test-retest reliability (ICC= 0.696, 95% CI: 0.581–0.783). The scale revealed moderate responsiveness when applied to patients with CLBP ( = 0.426 and AUC= 0.741, 95% CI: 0.645 - 0.837). The Smallest Detectable Change (SDC) was 19 points, whereas the Minimal Clinically Important Change (MCIC) ranged between 7 (ROC curve method) and 8 points (by the "mean difference score"). The estimate was derived from the ROC curve by an optimal cutoff point of 6.5 points, with Area Under the Curve (AUC)= 0.741, sensitivity 72%, and specificity of 71%. A complementary analysis of the ROC curve based on differences in QBPDS scores from baseline, expressed in percentage, revealed an optimal cutoff point of -24% (AUC= 0.737, sensitivity of 71%, and specificity of 71%). For the highest initial scores of QBPDS-PV (≥ 34 points) was found an optimal cutoff of 10.5 points (AUC= 0.738, sensitivity of 73%, and specificity 67%). Conclusion: The QBPDS-PV demonstrated good levels of reliability and responsiveness, being recommended its use in the measurement and evaluation of disability of patients with CLBP. The SDC of 19 points determined the QBPDS‟ scale width of 19 to 81. This study proposes MCIC values for QBPDS –PV for this specific setting (in CLBP patients who are referred for physiotherapy intervention). The QBPDS –PV baseline score have to be taken into account while interpreting the score change after physiotherapy intervention.

Thoracic Duct Decompression for Protein-Losing Enteropathy in Failing Fontan Circulation

An infrequent but devastating late complication of Fontan circulation is protein-losing enteropathy (PLE), which results from unbalanced lymphatic homeostasis. Surgical decompression of the thoracic duct by redirecting its drainage to the pulmonary venous atrium has been introduced recently as a possible treatment. This report describes a single-institution experience with this innovative procedure in 2 patients with failing Fontan circulation with PLE refractory to optimized medical therapy.

Adaptação cultural e contributo para a validação da escala petterns of activity measura - pain (POAM-P)

RESUMO: A dor lombar crónica (DLC) é uma das condições clínicas mais comuns e com elevados custos socioeconómicos no mundo ocidental. Estudos recentes indicam que os utentes com DLC apresentam diferentes padrões de atividade que influenciam os níveis de incapacidade funcional. Contudo, a evidência acerca destas associações é, ainda, limitada e inconclusiva. Em Portugal, não existe, do nosso conhecimento, nenhuma escala validada para a população portuguesa que meça estes padrões de atividade em utentes com DLC. Objetivos: Adaptar culturalmente a escala Patterns of Activity Measure – Pain (POAM-P) para a população portuguesa com dor lombar crónica inespecífica (DLCI) e contribuir para a sua validação. Metodologia: A versão original (inglesa) do POAM-P foi traduzida e adaptada para a língua portuguesa (POAM-P-VP) através de uma equipa multidisciplinar que incluiu tradutores, retrotradutores (cegos e independentes), peritos de diferentes áreas e utentes com DLCI, de acordo com as recomendações de linhas orientadoras atuais para este processo. A análise factorial e das propriedades psicométricas da POAM-P-VP contou com uma amostra de 132 utentes. A consistência interna foi analisada através do coeficiente alpha de Cronbach (α) e para a análise da fiabilidade teste-reteste recorreu-se ao coeficiente de correlação intraclasse (ICC:2,1). A análise da validade de construto convergente e discriminativa das componentes da POAM-P-VP foi conseguida através da aplicação da versão portuguesa da escala Tampa Scale of Kinesiophobia (TSK-13-VP), e recorrendo ao cálculo do coeficiente de Spearman. Todos os cálculos estatísticos foram realizados no software IBM SPSS Statistics (versão 20). Resultados: A análise factorial permitiu identificar três componentes da POAM-P-VP (evitamento, persistência excessiva e persistência consistente com a dor), sendo estruturalmente diferentes das subescalas do POAM-P original. Estas componentes apresentaram uma consistência interna boa a elevada. As componentes 1 e 2 apresentaram uma fiabilidade teste-reteste moderada a excelente, e a componente 3 uma fiabilidade teste-reteste pobre, limitando o seu poder de uso na prática clínica e em investigação. Relativamente à validade de construto, nenhuma das hipóteses estabelecidas no estudo apriori foram verificadas, não podendo aferir acerca da relação dos padrões de atividade com a cinesiofobia, medida pelo TSK-13-VP. Porém, a componente de evitamento da POAM-P-VP parece medir conteúdos partilhados com a TSK-13-VP (rs = 0.15, p<0.048). Conclusão: A adaptação e contributo para a validação da versão portuguesa da escala POAM-P constituiu um ponto de partida para a existência de um instrumento de medição de padrões de atividade de utentes portugueses com DLC, requerendo mais estudos para a sua validação. Apesar de algumas limitações, considera-se que este estudo é de grande importância para os fisioterapeutas e investigadores que buscam um maior conhecimento e efetividade das abordagens de intervenção em utentes com dor lombar crónica.-------------- ABSTRACT: Chronic low back pain (CLBP) is one of the most common clinical conditions as well as one with high economical costs within western countries. Recent studies have shown that patients with LBP present different patterns of activity which influence their levels of functional capacity. However, evidence on these associations is still limited and inconclusive. To our knowledge, there is in Portugal no valid scale for measuring these patterns of activity in CLBP patients. Purpose: Culturally adapt the Patterns of Activity Measure – Pain (POAM-P) scale to the Portuguese population with non-specific chronic low back pain (NSLBP) and contribute to its validation. Method: The original English version of POAM-P was blindly and independently translated, back translated and adapted to the Portuguese language (POAM-P-VP) by a multidisciplinary team of translators, experts from different fields, and patients with NSLBP, according to established guidelines for this process. Factorial and psychometric properties’ analysis of POAM-P-VP comprised a sample of 132 patients. The internal consistency was analyzed based on Cronbach's alpha-coefficient (α) and for test-retest reliability analysis the Intraclass Correlation Coefficient (ICC) was used. The analysis of convergent and discriminant construct validity of POAM-P-VP components was achieved through the use of the Portuguese version of the Tampa Scale of Kinesiophobia (TSK-13-VP), using the Spearman coefficient calculation. All statistical calculations were performed using IBM SPSS Statistics software (v.20). Results: The factor analysis allowed for the identification of three components of POAM-P-VP (avoidance, excessive persistence and pain-contingent persistence), structurally different from the original POAM-P subscales. These components demonstrated a good to high level of internal consistency. Components 1 and 2 demonstrated moderate to excellent test-retest reliability, whereas component 3 presented low test-retest reliability thus limiting its clinical and investigative use. With regard to construct validity, none of the previously established hypothesis was verified, therefore not making it possible to assess the relation between activity patterns and kinesiophobia, measured by TSK-13-VP. However, the avoidance component of POAM-P-VP seems to share measurable contents with TSK-13-VP (rs = 0.15, p<0.048). Conclusion: The adaptation and contribution to the validation of the Portuguese version of POAM-P scale, sets a starting point to the existence of a useful instrument for measuring activity patterns in Portuguese CLBP patients, requiring further studies towards its validation. Despite some limitations, this study is considered of high importance to physiotherapists as well as investigators in search of deeper knowledge and effective practical approaches on chronic low back pain patients.

Electromyography function, disability degree, and pain in leprosy patients undergoing neural mobilization treatment

INTRODUCTION: This study aimed to evaluate the effect of the neural mobilization technique on electromyography function, disability degree, and pain in patients with leprosy. METHODS: A sample of 56 individuals with leprosy was randomized into an experimental group, composed of 29 individuals undergoing treatment with neural mobilization, and a control group of 27 individuals who underwent conventional treatment. In both groups, the lesions in the lower limbs were treated. In the treatment with neural mobilization, the procedure used was mobilization of the lumbosacral roots and sciatic nerve biased to the peroneal nerve that innervates the anterior tibial muscle, which was evaluated in the electromyography. RESULTS: Analysis of the electromyography function showed a significant increase (p<0.05) in the experimental group in both the right (Δ%=22.1, p=0.013) and the left anterior tibial muscles (Δ%=27.7, p=0.009), compared with the control group pre- and post-test. Analysis of the strength both in the movement of horizontal extension (Δ%right=11.7, p=0.003/Δ%left=27.4, p=0.002) and in the movement of back flexion (Δ%right=31.1; p=0.000/Δ%left=34.7, p=0.000) showed a significant increase (p<0.05) in both the right and the left segments when comparing the experimental group pre- and post-test. The experimental group showed a significant reduction (p=0.000) in pain perception and disability degree when the pre- and post-test were compared and when compared with the control group in the post-test. CONCLUSIONS: Leprosy patients undergoing the technique of neural mobilization had an improvement in electromyography function and muscle strength, reducing disability degree and pain.

Degree of disability, pain levels, muscle strength, and electromyographic function in patients with Hansen's disease with common peroneal nerve damage

INTRODUCTION: This study evaluated the degree of disability, pain levels, muscle strength, and electromyographic function (RMS) in individuals with leprosy. METHODS: We assessed 29 individuals with leprosy showing common peroneal nerve damage and grade 1 or 2 disability who were referred for physiotherapeutic treatment, as well as a control group of 19 healthy participants without leprosy. All subjects underwent analyses of degree of disability, electromyographic tests, voluntary muscle force, and the Visual Analog Pain Scale. RESULTS: McNemar's test found higher levels of grade 2 of disability (Δ = 75.9%; p = 0.0001) among individuals with leprosy. The Mann-Whitney test showed greater pain levels (Δ = 5.0; p = 0.0001) in patients with leprosy who had less extension strength in the right and left extensor hallucis longus muscles (Δ = 1.28, p = 0.0001; Δ = 1.55, p = 0.0001, respectively) and dorsiflexion of the right and left feet (Δ = 1.24, p = 0.0001; Δ = 1.45, p = 0.0001, respectively) than control subjects. The Kruskal-Wallis test showed that the RMS score for dorsiflexion of the right (Δ = 181.66 m·s-2, p = 0.001) and left (Δ = 102.57m·s-2, p = 0.002) feet was lower in patients with leprosy than in control subjects, but intragroup comparisons showed no difference. CONCLUSIONS: Leprosy had a negative influence on all of the study variables, indicating the need for immediate physiotherapeutic intervention in individuals with leprosy. This investigation opens perspectives for future studies that analyze leprosy treatment with physical therapeutic intervention.

Indicadores de prognóstico em utentes com disfunção do ombro submetidos a uma intervenção terapêutica direcionada para a estabilidade dinâmica da escápulo-torácica

RESUMO: Introdução/ Objetivo: Segundo a revisão sistemática de Chester e colaboradores (2013b)apenas dois fatores de prognóstico demonstraram uma associação consistente com o resultado que foram a duração dos sintomas e a funcionalidade na avaliação inicial. O objetivo do estudo é identificar indicadores de bom e mau prognóstico em utentes com disfunção do complexo articular do ombro (DCAO), tendo por base, aspetos da avaliação inicial do utente e critérios de alta de abolição da dor, aumento da funcionalidade e da estabilidade dinâmica considerando uma intervenção terapêutica direcionada para o aumento da estabilidade dinâmica da escápulo-torácica. Metodologia: Efetuou-se um estudo de coorte clínico retrospetivo. Para tal, aplicou-se um protocolo de intervenção terapêutica e analisou-se os resultados. A amostra foi constituída por 82 indivíduos com DCAO [53 com síndrome do conflito subacromial (SCSA) e 29 com instabilidade da glenoumeral (IGU)], residentes nos distritos de Lisboa, Setúbal e Santarém com o intuito de iniciar tratamento de fisioterapia. A análise dos dados foi efetuada tendo em consideração dois procedimentos: análise univariada (através do método de Kaplan-Meier para cada CVP) e análise multifatorial (pela análise de regressão de Cox e regressão logística nos grupos de utentes com SCSA, IGU e DCAO). Resultados: O tempo mediano de continuação no tratamento em fisioterapia foi de 7 semanas para os utentes com SCSA e 6 semanas para utentes com IGU. Segundo o teste de Logrank, na análise univariada, existem sete e oito covariáveis preditoras (CVP) com associação estatisticamente significativa (p<0,05) para o subgrupo SCSA e IGU, respectivamente. De acordo com estes resultados, a primeira parte da DASH e a SPADI são as únicas CVP com associação comuns às duas disfunções. Pela análise multifatorial e, em congruência com o teste de Wald, nenhuma das CVP contribui estatisticamente para o modelo preditivo de continuidade do tratamento de fisioterapia em qualquer um dos três modelos estudados: subgrupo SCSA, subgrupo IGU e utentes com DCAO. Conclusão: Por uma análise univariada verificou-se que existem CVP associadas à alta dos tratamentos em fisioterapia e estas não são as mesmas em ambas as DCAO. Contudo, a magnitude do efeito de cada CVP nos modelos multifatoriais definidos para os grupos de utentes com SCSA, IGU e DCAO não demonstraram valor estatisticamente significativo pelo que não foi possível determinar modelos de prognóstico em utentes com DCAO.-------------ABSTRACT: Background/ Purpose: According with the systematic review from Chester and collaborators (2013b) just two prognostic factors demonstrated a consistent association with the outcome: the duration of symptoms and functionality in the initial assessment. The purpose of the study is to identify indicators of good and poor prognosis in patients with shoulder’s dysfunctions, based on aspects of the initial assessment and discharge criteria of absence of pain, increased functionality and dynamic stability considering a therapeutic intervention used to increase the dynamic stability of scapulo-thoracic. Methodology: It was conducted a retrospective study of clinical cohort. For this purpose it was applied a protocol with therapeutic intervention and the results were analyzed. The sample consisted of 82 individuals with shoulder’s dysfunction (53 with subacromial impingement (SIMP) and 29 with shoulder instability (SINS) residing in the districts of Lisbon, Setúbal and Santarém in order to start physiotherapy. Data analysis was performed taking into account two procedures: univariate analysis [using the Kaplan-Meier method for each co-variant predictor variable (CVP)] and multifactorial analysis [analysis by Cox regression and logistic regression on groups of patients with SIMP, SINS and shoulder’s dysfunction (SD)]. Results: The median time of follow-up treatment at physical therapy was 7 weeks for patients with SIMP and 6 weeks for patients with SINS. According to the Logrank test in the univariate analysis, there are seven and eight CVP with a statistically significant association (p<0.05) for the patients with SIMP and SINS, respectively. According to these results, the first part of the DASH and SPADI are the only CVP common to both disorders association. By multifatorial analyses, and in agreement with the Wald test, none of the CVP contributes statistically to the predictive model of continuity of physiotherapy treatment in any of the three studied models: patients with SIMP, patients with SINS and patients with SD. Conclusion: In an univariate analysis, it was verified that there are CVP associated with discharge from treatments of physical therapy and these are not the same in both SD. However, the magnitude of effect of each CVP in multifactorial models for defined patients groups with SIMP, SINS and SD showed no statistically significant. Therefore, it was not possible to determine prognostic models for patients with SD.

Adaptação cultural e contributo para a validação da pain attitudes and believes scale for physiotherapists (PABS-PT) para a população de fisioterapeutas portugueses

RESUMO: Introdução: Vários estudos têm encontrado evidência para a relação entre as crenças e atitudes dos profissionais de saúde, a sua abordagem de tratamento, referida como orientada segundo o modelo biomédico ou modelo biopsicossocial (Bishop, 2008; Mutsaers, 2012), e os resultados obtidos. É sugerido que, no tratamento da dor lombar crónica, os profissionais que orientam o seu raciocínio e prática segundo o modelo biomédico, tendem a obter piores resultados quando comparados com os obtidos pelos profissionais que orientam o seu raciocínio e prática segundo uma abordagem biopsicossocial. Esta área de estudo tem salientado a importância de desenhar instrumentos capazes de identificar a orientação preferencial dos profissionais de saúde no tratamento da dor crónica de natureza músculo-esquelética, entre os quais se encontra a “Pain Attitudes and Beliefs Scale for Physiotherapists” (PABS-PT). Objetivo: Adaptar culturalmente a PABS-PT para a população de fisioterapeutas portugueses que intervêm em utentes com dor (lombar) crónica, e contribuir para a sua validação Metodologia: A versão original (língua inglesa) do PABS-PT foi adaptada para a língua e cultura portuguesas, através das etapas definidas nas normas orientadoras estabelecidas para este processo (Beaton et al., 2002; MAPI Institute, 2001). A avaliação das propriedades psicométricas da versão portuguesa foi realizada com recurso a uma amostra de 202 fisioterapeutas e estudantes finalistas do curso de licenciatura em Fisioterapia. Inicialmente foi realizada a análise fatorial exploratória da escala através do método das componentes principais. Posteriormente avaliou-se a consistência interna das componentes obtidas com recurso ao alpha de Cronbach (α). Para analisar a validade de constructo foram correlacionadas as componentes obtidas com a versão portuguesa da “Health Care Providers’ Pain and Impairment Relationship Scale” (HC-PAIRS), recorrendo ao cálculo do coeficiente de Spearman. Resultados: O processo de adaptação cultural não revelou dificuldades importantes sendo considerado que a versão portuguesa da PABS-PT é de fácil compreensão e preenchimento, e os seus itens adequados para avaliar as crenças e atitudes dos fisioterapeutas portugueses relativas à intervenção na dor crónica músculo-esquelética. Os resultados revelaram uma estrutura fatorial de duas componentes, identificadas com as componentes da escala original que explicam 30,96% da variância total. A consistência interna encontrada é boa, para a componente biomédica (α de Cronbach = 0,826), mas muito fraca para a componente biopsicossocial (α de Cronbach= 0,589). Relativamente à validade convergente e discriminativa, foi encontrada uma associação estatisticamente significativa e positiva, entre as componentes 1 (biomédica) da versão nportuguesa da PABS e a HC-PAIRS (Rs = 0,481, p≤ 0,005), e negativa, fraca e significativa entre a pontuação total da componente 2 (biopsicossocial) e a HC-PAIRS (Rs = -0,038, p=0,612). Conclusão: A versão portuguesa do PABS-PT é de fácil compreensão e aparenta ser um instrumento válido para a medição da orientação preferencial dos fisioterapeutas, relativamente às suas atitudes e crenças na avaliação e tratamento de utentes com dor crónica de natureza músculo-esquelética. No entanto, a componente biopsicossocial requer uma análise mais aprofundada para que possa, com rigor, ser utilizada na definição de uma orientação preferencialmente biopsicossocial.--------------ABSTRACT: Introduction: Previous studies have found a relation between the beliefs and attitudes of health professionals, their treatment approach, which can follows a biomedical or a biopsychosocial orientation (Bishop, 2008; Mutsaers, 2012), and the outcomes obtained. Therefore, is suggested that the professionals who tend to approach chronic low back pain patients according to the biomedical model have worse outcomes than professionals who use a biopsychosocial approach in there clinical reasoning. This research field has highlighted the importance of developing measures capable of identifying the preferred orientation of health professionals in the treatment of chronic pain of musculoskeletal nature, including the “Pain Attitudes and Beliefs Scale for Physiotherapists” (PABS-PT). Objective: To cross culturally adapt and validate the PABS-PT for the Portuguese population of physiotherapists. Methodology: The original version (English version) of the PABS-PT was adapted to the Portuguese language and culture, through the guidelines established for these processes (Beaton et al., 2002; MAPI Institute, 2001). The psychometric evaluation of the Portuguese version was carried out on a sample of 202 p physiotherapist and final year students of the physiotherapy course. Initially, an exploratory factorial analysis was performed through the method of the main components. Then, the internal consistence of the main components was evaluated using the Cronbach’s alpha (α). The convergent construct validity was analysed through the correlation between the obtained components of PABS-PT and the Health Care Provider’s Pain and Impairment Relationship Scale (HC-PAIRS), using the Spearmen correlation coefficient. Results: No major difficulties were found during the cultural adaptation process of PABS-PT to Portugal, which means that the Portuguese version is easy to understand and fulfill, and items are appropriated to evaluate the beliefs and attitudes of the Portuguese physiotherapists who treat chronic pain of musculoskeletal origins. The results revealed a factorial structure of two components, as the original scale, explaining 30,96% of the total variance. Internal consistence results were good, for the biomedical component (Cronbach’s α = 0,826), but very weak for the biopsychosocial componente (Cronbach’s α = 0,589). Relatively to convergent and discriminative validity, a statistically significant association was found, between the components 1 (biomedical) of the Portuguese version of PABS-PT and the HC-PAIRS (Rs= 0,481, p≤ 0,005) and negative, weak and significant between the total score of component 2 (biopsychosocial) and the HC-PAIRS (Rs = -0,038, p=0,612). Conclusion: The Portuguese Version of PABS-PT is easy to understand and seems to be a valid instrument to measure the attitudes and beliefs of physiotherapists in the management of patients with chronic low back pain. However, the biopsychosocial component requires a further deep analysis to examine a preferable biopsychosocial orientation.

Bone tuberculosis: a case report on child

The authors report a case of a 12-year-old child with a complaint of pain and deformity in the lower thoracic region that had lasted for two years. Clinical, epidemiological and laboratory characteristics associated with images of apparent damage in the T9-T10 and T11-T12 vertebrae taken by radiography of the thoracic spine and nuclear magnetic resonance in addition to the positivity of the molecular test based on the polymerase chain reaction, led to tuberculous spondylitis being diagnosed and specific therapy was started. Culture of vertebral biopsy was positive for Mycobacterium tuberculosis after thirty days.
