Tradução e validação de conteúdo da versão em português do Childhood Trauma Questionnaire

OBJETIVO: O Childhood Trauma Questionnaire é um instrumento auto-aplicável em adolescentes e adultos que investigam história de abuso e negligência durante a infância. O objetivo do trabalho foi de traduzir, adaptar e validar o conteúdo do questionário para uma versão em português denominada Questionário Sobre Traumas na Infância. MÉTODOS: O processo de tradução e adaptação envolveu cinco etapas: (1) tradução; (2) retradução; (3) correção e adaptação semântica; (4) validação do conteúdo por profissionais da área (juízes) e (5) avaliação por amostra da população-alvo, por intermédio de uma escala verbal-numérica. RESULTADOS: As 28 questões e as instruções iniciais traduzidas e adaptadas criaram o Questionário Sobre Traumas na Infância. Na avaliação pela população-alvo, 32 usuários adultos do Sistema Único de Saúde responderam a avaliação, com boa compreensão do instrumento na escala verbal-numérica (média=4,86±0,27). CONCLUSÕES: A versão mostrou ser de fácil compreensão obtendo-se adequada validação semântica. Entretanto, ainda carece de estudos que avaliem outras qualidades psicométricas.

Occupational exposure to particulate matter and respiratory symptoms in Portuguese swine barn workers

Certain environmental conditions in animal and plant production have been associated with increased frequency in respiratory illnesses, including asthma, chronic bronchitis, and hypersensitivity pneumonitis, in farmers occupationally exposed in swine production. The aim of this study was to characterize particulate matter (PM) contamination in seven Portuguese swine farms and determine the existence of clinical symptoms associated with asthma and other allergy diseases, utilizing the European Community Respiratory Health Survey questionnaire. Environmental assessments were performed with portable direct-reading equipment, and PM contamination including five different sizes (PM0.5, PM1.0, PM2.5, PM5.0, PM10) was determined. The distribution of particle size showed the same trend in all swine farms, with high concentrations of particles with PM5 and PM10. Results from the questionnaire indicated a trend such that subjects with diagnosis of asthma were exposed to higher concentrations of PM with larger size (PM2.5, PM5, and PM10) while subjects with sneezing, runny nose, or stuffy nose without a cold or flu were exposed to higher concentrations of PM with smaller size (PM0.5 and PM1). Data indicate that inhalation of PM in swine farm workers is associated with increased frequency of respiratory illnesses.

Factors associated with depression symptoms in high school students in São Paulo, Brazil

OBJECTIVE: To assess factors associated with depression symptoms in high school students. METHODS: A cross-sectional study involving high school students was conducted in the city of São Paulo, Brazil, 2001. A total of 724 students aged 14-18 years answered questionnaires on life and health conditions. Another questionnaire was applied to working (44.8%) and unemployed (22.9%) students to collect information on working conditions. Factors associated to depressive disorders were analyzed using multiple logistic regression controlled for occupational status. RESULTS: Overall prevalence rate of depression was 7.5%. Rates according to gender were 39 (10.3%) in females and 15 (4.3%) in males. The multiple logistic regression analysis showed that factors associated with depressive disorders were: poor self-perception of health (OR=5.78), being female (OR = 2.45), and alcohol consumption (OR=2.35). CONCLUSIONS: The study results showed that sociodemographic, lifestyle and health variables were associated with symptoms of depression in this population. These ndings suggest that it is important to have mental health professionals available in high schools for early detection of mental conditions and student counseling.

Clinical and functional aspects of work-related musculoskeletal disorders among active workers

OBJECTIVE: To evaluate musculoskeletal disorders among active industrial workers. METHODS: The study was carried out in São Carlos, Southeastern Brazil, in 2005. One hundred and thirty-four female workers were physically evaluated and answered questions about their physical symptoms, filled out a pain scale and gave responses in the Oswestry Disability Questionnaire, and the Work Ability Index questionnaire. The data were analyzed descriptively, and in correlation tests and through applying logistic regression. The outcome was evaluated in relation to the perceptions of pain, symptoms, physical assessment, ability to work and disability. RESULTS: Clinical evaluations and sick leave presented positive correlations with the subjective variables. The Work Ability Index presented a negative correlation with the physical disability index (r=-0.69). Symptoms reported at the time of the assessment presented a good correlation with the results from the pain scale and the clinical findings. Previous sick leave showed an association with disability (OR=1.13; 95% CI:1.08;1.18). CONCLUSION: Symptom reports and pain scales may be useful for assessing current conditions at the time of evaluating individuals with work-related musculoskeletal disorders, as they are easier to apply. In more severe cases of such injuries, clinical and functional evaluations and questionnaires such as those relating to ability to work and disability are preferable. Precise and specific evaluations of these disorders may contribute towards fairer legal and administrative decisions.

Qualidade de vida de vítimas de trauma seis meses após a alta hospitalar

OBJETIVO: O trauma ocupa o terceiro lugar dentre as causas de morte no Brasil. Contudo, seu impacto na qualidade de vida dos sobreviventes tem sido pouco estudado no País. O objetivo do estudo foi avaliar a qualidade de vida de vítimas de trauma atendidas em unidade hospitalar de emergências, seis meses após a alta hospitalar. MÉTODOS: Foram incluídos 35 pacientes de unidade de emergência de hospital universitário de Ribeirão Preto (SP), entre 2005 e 2006. Os pacientes foram entrevistados em seus domicílios, seis meses após terem tido alta hospitalar. Foi aplicado o instrumento World Health Organization Quality of Life, versão breve, para avaliação dos domínios físico, psicológico, relações sociais e meio ambiente. As associações entre os escores dos domínios e as variáveis permanência hospitalar, idade, sexo e Injury Severity Score foram exploradas por modelos de regressão linear. RESULTADOS: Observou-se diminuição significativa na qualidade de vida do grupo estudado, quando comparado a amostras de pessoas normais em estudos nacionais e internacionais, em particular nos domínios físico, psicológico e de meio ambiente. O domínio relações sociais apresentou a maior média de escores, com 69,7 pontos, enquanto o domínio meio ambiente recebeu a menor pontuação (52,4), ambos na escala percentual. As variáveis associadas a domínio físico foram permanência hospitalar (p=0,02), idade (p<0,01) e sexo (p=0,03). Para os demais domínios, a análise não mostrou associação com as variáveis estudadas. CONCLUSÕES: As vítimas de trauma apresentaram diminuição nos escores de qualidade de vida. Embora o aspecto físico tenha sido o mais atingido, há evidências de que os domínios psicológico e de meio ambiente permaneceram distantes das condições ideais esperadas para a população em geral.

Depressive symptoms in institutionalized older adults

OBJECTIVE To estimate the prevalence of depressive symptoms among institutionalized elderly individuals and to analyze factors associated with this condition. METHODS This was a cross-sectional study involving 462 individuals aged 60 or older, residents in long stay institutions in four Brazilian municipalities. The dependent variable was assessed using the 15-item Geriatric Depression Scale. Poisson’s regression was used to evaluate associations with co-variables. We investigated which variables were most relevant in terms of presence of depressive symptoms within the studied context through factor analysis. RESULTS Prevalence of depressive symptoms was 48.7%. The variables associated with depressive symptoms were: regular/bad/very bad self-rated health; comorbidities; hospitalizations; and lack of friends in the institution. Five components accounted for 49.2% of total variance of the sample: functioning, social support, sensory deficiency, institutionalization and health conditions. In the factor analysis, functionality and social support were the components which explained a large part of observed variance. CONCLUSIONS A high prevalence of depressive symptoms, with significant variation in distribution, was observed. Such results emphasize the importance of health conditions and functioning for institutionalized older individuals developing depression. They also point to the importance of providing opportunities for interaction among institutionalized individuals.

Screening for depressive symptoms in older adults in the Family Health Strategy, Porto Alegre, Brazil

OBJECTIVE To analyze the prevalence of depression in older adults and associated factors. METHODS Cross-sectional study using a stratified random sample of 621 individuals aged ≥ 60 from 27 family health teams in Porto Alegre, RS, Southern Brazil, between 2010 and 2012. Community health agents measured depression using the 15-item Geriatric Depression Scale. Scores of ≥ 6 were considered as depression and between 11 and 15 as severe depression. Poisson regression was used to search for independent associations of sociodemographic and self-perceived health with both depression and its severity. RESULTS The prevalence of depression was 30.6% and was significantly higher in women (35.9% women versus 20.9% men, p < 0.001). The variables independently associated with depression were: female gender (PR = 1.4, 95%CI 1.1;1.8); low education, especially illiteracy (PR = 1.8, 95%CI 1.2;2 6); regular self-rated health (OR = 2.2, 95%CI 1.6;3.0); and poor/very poor self-rated health (PR = 4.0, 95%CI 2.9;5.5). Except for education, the strength of association of these factors increases significantly in severe depression. CONCLUSIONS A high prevalence of depression was observed in the evaluations conducted by community health agents, professionals who are not highly specialized. The findings identified using the 15-item Geriatric Depression Scale in this way are similar to those in the literature, with depression more associated with low education, female gender and worse self-rated health. From a primary health care strategic point of view, the findings become still more relevant, indicating that community health agents could play an important role in identifying depression in older adults.

Asthenopic symptoms and binocular vision of professional users of optical microscope

Desde 1935 que tem sido demonstrada a relação entre a execução de um trabalho de perto prolongado e o aparecimento de queixas visuais astenópicas. Anomalias da VB encontram-se significativamente aumentadas ao fim de um dia de trabalho com fixação de perto. Diminuição significativa da amplitude de acomodação e convergência depois de quatro dias a realizar uma atividade de perto. Objectivo geral: avaliar o estado da visão binocular dos profissionais de Anatomia Patológica utilizadores de microscópio ótico. Objectivos específicos: identificar as queixas astenópicas mais frequentes dos profissionais durante o trabalho com o microscópio ótico; comparar o estado da VB no início e no final de uma semana de trabalho; correlacionar o estado da VB com as queixas astenópicas sentidas pelos profissionais; correlacionar as queixas astenópicas com as horas e o número de anos de trabalho com o microscópio.

Validity of selected clinical signs and symptoms in diagnosis of Schistosoma mansoni infection

Sensitivity, specificity and positive predictive values of selected clinical signs and symptoms in the diagnosis of Schistosoma mansoni infection were evaluated in 403 individuals (69% of inhabitants over 1 year of age) in an endemic area in Brazil (Divino). Highest sensitivity (13%) was found for blood in stools. Specificity over 90% was found for blood in stools, palpable liver with normal consistency and palpable hardened liver at middle clavicular (MCL) or middle sternal lines (MSL). Hardened liver at MSL (83%) or MCL (75%), and blood in stools (78%) presented higher positive predictive values for S. mansoni infection, while palpable liver with normal consistency at MCL (45%) or MSL (48%) presented smaller values. Enlarged liver without specification of its consistency has been traditionally used as an indicator of the infection in areas where malaria or Kalazar are not endemic. Our results demonstrate that the probability that a person with blood in stools or hardened palpable liver is infected is higher than among those with palpable liver with normal consistency.

Relevant prevalence of Mycoplasma hominis and Ureaplasma urealyticum serogroups in HIV-1 infected men without urethritis symptoms

M. hominis and U. urealyticum are the better-known mycoplasma species pathogenic to the human genitourinary tract, causing mainly urethritis, bacterial vaginosis and pregnancy complications. In HIV-infected patients, the prevalence and role of these species is still not well known. The aim of this work was to determinate the prevalence of these species in this group of male patients (HIV group), in comparison to a group of men with clinical symptoms of urethritis (STD group). M. hominis was isolated from 7.5% patients (8/106) and U. urealyticum from 18.9% patients (20/106) from the HIV group, being among these 62.5% and 85% in significant concentrations, respectively. In the STD group these rates were 0.9% (1/110) for M. hominis and 13.6% (15/110) for U. urealyticum, being 100% and 93.3% in significant concentrations, respectively. We could demonstrate infection rates by these mycoplasma species in the HIV group as high as the one found in the STD one, what may indicate the occurrence of opportunistic infections in our population. This fact is discussed here because in immunosuppressed patients, specially M. hominis has been reported causing severe infections, even systemically.

A Memória e o Impacto do Trauma: Numa Perspectiva Desenvolvimental

Pretende-se realizar uma revisão sobre as estruturas neuroanatómicas e os processos de neurotransmissão e de modulação neuronal envolvidos na memória. A memória é vista como um processo activo, baseado na reunião de variados aspectos dos padrões de activação neuronal, num processo dependente da experiência. Descreve-se a importância das regiões límbicas e sua inter-relação no processamento da memória, desde a codificação até à consolidação que implica uma reestruturação neuronal. Procede-se à caracterização dos tipos de memória (implícita e explícita) e suas características,a relação com as diferentes fases do desenvolvimento, tocando alguns aspectos mais descritivos de diferentes componentes da memória. Numa perspectiva contextual são também focadas as áreas da amnésia infantil, a lembrança, o esquecimento e o trauma. O esquecimento é parte essencial da memória explícita. Vários estudos apontam para um efeito de curva em U invertida, em relação com o impacto emocional. Eventos com intensidade moderada a elevada parecem ser etiquetados como importantes (envolvimento de estruturas do sistema límbico como a amígdala e o córtex orbito-frontal) e são mais facilmente recordadas no futuro. Se os eventos são muitos intensos o processamento no hipocampo da codificação memoria explícita e subsequentemente a recordação são inibidos,há também um bloqueio da consolidação cortical da experiência, porém mantém-se a memória implícita, que pode levar a vivência de imagens intrusivas não elaboradas. No que concerne ao trauma, levanta-se a questão da precisão da memória e do seu impacto, tanto ao nível das implicações neurofisiológicas como das consequências psicopatológicas. As alterações ao nível das neurotransmissões induzidas pelo stress vão condicionar alterações na mielinização, sinaptogénese e neurogénese, que podem levar a alterações a longo prazo em várias regiões do cérebro entre as quais a amígdala. Nestas condições, o processo explícito e a aprendizagem podem ser cronicamente impedidas, para além do risco importante para o desenvolvimento de psicopatologia, nomeadamente: Perturbação da Personalidade, Perturbações de Humor (depressão); Perturbações de Ansiedade; Perturbações Dissociativas e maior risco de Psicose.

Aracnoidite Adesiva Lombar

Spinal arachnoiditis, an inflammatory process involving all three meningeal layers as well as the nerve roots, is a cause of persistent symptoms in 6% to 16% of postoperative patients. Although spinal surgery is the most common antecedent associated with arachnoiditis, multiple causes have been reported, including infection, intrathecal steroids or anesthetic agents, trauma, subarachnoid hemorrhage and ionic myelographic contrast material--both oil soluble and water soluble. In the past, oil-based intrathecal contrast agents (Pantopaque) were associated with arachnoiditis especially when this material was introduced into the thecal sac and mixed with blood. Arachnoiditis is apparently rarely idiopathic. The pathogenesis of spinal arachnoiditis is similar to the repair process of serous membranes, such as the peritoneum, with a negligible inflammatory cellular exudate and a prominent fibrinous exudate. Chronic adhesive arachnoiditis of the lower spine is a myelographic diagnosis. The myelographic findings of arachnoiditis were divided into two types by Jorgensen et al. In type 1, "the empty thecal sac" appearance, there is homogeneous filling of the thecal sac with either absence of or defects involving nerve root sleeve filling. In type 2 arachnoiditis, there are localized or diffuse filling defects within the contrast column. MRI has demonstrated a sensitivity of 92% and a specificity of 100% in the diagnosis of arachnoiditis. The appearance of arachnoiditis on MRI can be assigned to three main groups. The MRI findings in group I are a conglomeration of adherent roots positioned centrally in the thecal sac. Patients in group II show roots peripherally adherent to the meninges--the so called empty sac. MRI findings in group III are a soft tissue mass within the subarachnoid space. It corresponds to the type 2 categorization defined by Jorgensen et al, where as the MRI imaging types I and II correspond to the myelographic type 1.

Minimal Criteria for the Diagnosis of Avulsion of the Puborectalis Muscle by Tomographic Ultrasound

Introduction and hypothesis Puborectalis avulsion is a likely etiological factor for female pelvic organ prolapse(FPOP). We performed a study to establish minimal sonographic criteria for the diagnosis of avulsion. Methods We analysed datasets of 764 women seen at a urogynecological service. Offline analysis of ultrasound datasets was performed blinded to patient data. Tomographic ultrasound imaging (TUI) was used to diagnose avulsion of the puborectalis muscle. Results Logistic regression modelling of TUI data showed that complete avulsion is best diagnosed by requiring the three central tomographic slices to be abnormal. This finding was obtained in 30% of patients and was associated with symptoms and signs of FPOP (P<0.001). Lesser degrees of trauma (‘partial avulsion’) were not associated with symptoms or signs of pelvic floor dysfunction. Conclusions Complete avulsion of the puborectalis muscle is best diagnosed on TUI by requiring all three central slices to be abnormal. Partial trauma seems of limited clinical relevance.

Tradução com adaptação cultural para portugês e determinação da reprodutibilidade do questionnaire on respiratory symptoms in preschool children

RESUMO: Introdução: A asma brônquica é uma entidade frequente em idade pediátrica, apresentando uma grande heterogeneidade clínica e significativa morbilidade quando não controlada. A identificação de crianças sintomáticas pode atrasar ou até mesmo diminuir a ocorrência de algumas alterações estruturais. Reconhece-se a necessidade de questionários sobre sintomas respiratórios em língua portuguesa, devidamente validados, que tenham como população-alvo os grupos etários inferiores a 3 anos. Deste modo, será possível não só um conhecimento mais rigoroso da asma e da sibilância infantil mas também a uniformização de metodologias para o desenvolvimento de estratégias a nível nacional. Objetivos: Tradução com adaptação cultural para português e determinação da reprodutibilidade do Questionnaire on respiratory symptoms in preschool children de Strippoli e colaboradores. Material e métodos: A escolha do questionário obedeceu a vários critérios, entre os quais o grupo etário, o tipo e número de perguntas. O Questionnaire on respiratory symptoms in preschool children de Strippoli e colaboradores é um questionário de autopreenchimento, dirigido a crianças entre os 12 e os 24 meses de idade e destinado a estudos epidemiológicos ao nível da comunidade. Aborda aspetos referentes a sintomas respiratórios (sibilância, tosse crónica, sintomas das vias aéreas superiores), cuidados médicos, terapêutica, características ambientais, história familiar e situação social. Procedemos à sua tradução, com especial atenção para a adaptação do ponto de vista cultural e linguístico, utilizando o método da tradução / retroversão, amplamente utilizado e descrito na literatura internacional. Seguidamente determinámos a reprodutibilidade da versão final em língua portuguesa – Questionário de sintomas respiratórios em idade pré-escolar – utilizando o teste-reteste. Para tal, incluíram-se crianças entre os 12 e os 36 meses de idade recrutadas num Centro de Saúde e em creches de Lisboa. A distribuição dos questionários decorreu em duas fases: na primeira fase foram entregues pessoalmente nos locais de recrutamento e na segunda fase foram enviados por correio para os domicílios das crianças, respeitando-se um intervalo mínimo de 2 semanas entre ambos. Resultados: Na primeira fase foram distribuídos 180 questionários, com uma taxa de reposta de 41% (n=74). Na segunda fase enviaram-se para os respetivos domicílios 70 questionários,obtendo-se uma taxa de resposta de 66% (n=46). Para a análise de reprodutibilidade foram incluídos apenas os questionários preenchidos em ambos os momentos pelo mesmo indivíduo (mãe, pai ou representante legal) (n=41). A idade média das crianças foi, na primeira fase, de 22,5 meses e, na segunda fase, de 23,7 meses, com um predomínio do sexo feminino (F:M =1:0,6). A mediana do tempo decorrido entre os dois momentos de preenchimento dos questionários foi de 26 dias. Obtivemos valores de concordância globalmente bons a muito bons, à semelhança do sucedido no trabalho original. Conclusões: Procedemos à tradução e avaliação da reprodutibilidade do Questionnaire on respiratory symptoms in preschool children. Pretende-se que venha a ser uma ferramenta útil para estudos epidemiológicos e programas de rastreio na comunidade, contribuindo deste modo para uma otimização da abordagem da asma / sibilância infantil a nível nacional. -------------ABSTRACT: Background: Asthma is a very common feature in childhood, with important clinical heterogeneity and morbidity if not properly controlled. Identifying symptomatic children may delay or even reduce several structural changes. The development of questionnaires on respiratory symptoms in Portuguese for children under 3 years old will allow not only a more accurate knowledge of infantile asthma and recurrent wheezing but also the standardization of methodologies to develop nationwide strategies. Objectives: The aim of this study was to translate and adapt to the Portuguese culture and to determine the repeatability of the Questionnaire on respiratory symptoms in preschool children by Strippoli et al. Material and methods: The choice of the questionnaire took in consideration several criteria, among which the target age, the type and the number of questions. The Questionnaire on respiratory symptoms in preschool children by Strippoli et al is a parent-completed questionnaire for assessment of respiratory symptoms in 1 to 2-year-old children, developed for cross-sectional and longitudinal studies. It contains sections on respiratory symptoms (wheezing, chronic cough and upper airways symptoms), healthcare utilization, treatment, environmental exposure, family history and social situation. For the process of translation we used the method of translation and back-translation, with particular concern to cultural and linguistic adaptation. To assess the repeatability of the final Portuguese version - Questionário de sintomas respiratórios em idade pré-escolar - we used the test–retest analyses. The questionnaires were distributed to parents of children between 12 and 36 months old attending nurseries and a Primary Care Center of Lisbon. The distribution took place in two phases: the first questionnaires were delivered in person (phase one) and an identical questionnaire was posted to the families that participated in the first phase, 2 weeks after the first one was returned (phase two). Results: The response rates were 41% (180/74) in the first phase and 66% (70/46) in the second phase. For test–retest analyses, we included the 41 children with the same respondent (mother, father or legal representative) in both occasions. The median age of the children was 22,5 months at the first phase and 23,7 months at the second phase, with a predominance of girls (F:M = 1:0,6). The median time between the fillings of both questionnaires was 26 days. Globally, agreement values were good to excellent, similarly to the original work. Conclusion: In the present study we translated the Questionnaire on respiratory symptoms in preschool children and assessed its repeatability. Overall, we expect it to be a valuable tool for epidemiological studies and community-based screening programs, thus contributing to improve the management of infantile asthma / recurrent wheezing nationwide.

Unilateral Versus Bilateral Prostatic Arterial Embolization for Lower Urinary Tract Symptoms in Patients with Prostate Enlargement

PURPOSE: This study was designed to compare baseline data and clinical outcome between patients with prostate enlargement/benign prostatic hyperplasia (PE/BPH) who underwent unilateral and bilateral prostatic arterial embolization (PAE) for the relief of lower urinary tract symptoms (LUTS). METHODS: This single-center, ambispective cohort study compared 122 consecutive patients (mean age 66.7 years) with unilateral versus bilateral PAE from March 2009 to December 2011. Selective PAE was performed with 100- and 200-μm nonspherical polyvinyl alcohol (PVA) particles by a unilateral femoral approach. RESULTS: Bilateral PAE was performed in 103 (84.4 %) patients (group A). The remaining 19 (15.6 %) patients underwent unilateral PAE (group B). Mean follow-up time was 6.7 months in group A and 7.3 months in group B. Mean prostate volume, PSA, International prostate symptom score/quality of life (IPSS/QoL) and post-void residual volume (PVR) reduction, and peak flow rate (Qmax) improvement were 19.4 mL, 1.68 ng/mL, 11.8/2.0 points, 32.9 mL, and 3.9 mL/s in group A and 11.5 mL, 1.98 ng/mL, 8.9/1.4 points, 53.8 mL, and 4.58 mL/s in group B. Poor clinical outcome was observed in 24.3 % of patients from group A and 47.4 % from group B (p = 0.04). CONCLUSIONS: PAE is a safe and effective technique that can induce 48 % improvement in the IPSS score and a prostate volume reduction of 19 %, with good clinical outcome in up to 75 % of treated patients. Bilateral PAE seems to lead to better clinical results; however, up to 50 % of patients after unilateral PAE may have a good clinical outcome.
