Comparison between clinical and ultrasonographic findings in cases of periportal fibrosis in an endemic area for schistosomiasis mansoni in Brazil

INTRODUCTION: Abdominal palpation and ultrasound findings among patients from an endemic area for schistosomiasis in Brazil who had been followed up for 27 years were compared. METHODS: In 2004, 411 patients from Brejo do Espírito Santo, in the State of Bahia, were selected for the present investigation after giving their written informed consent. Based on clinical data, they were divided into three groups: 41 patients with evidence of liver fibrosis in 2004 (Group 1); 102 patients with evidence of liver fibrosis in the past (1976-1989) but not in 2004 (Group 2); and 268 patients without evidence of liver fibrosis at any time during the 27-year follow-up (Group 3). All of the patients underwent abdominal ultrasound in which the examiner did not know the result from the clinical examination. The data were stored in a database. RESULTS: The prevalence of periportal fibrosis on ultrasound was 82.9%, 56.9% and 13.4% in Groups 1, 2 and 3, respectively. In the presence of hard, nodular liver or prominent left lobe and a hard palpable spleen, ultrasound revealed periportal fibrosis in 70.9%. However, periportal fibrosis was diagnosed using ultrasound in 25.4% of the patients in the absence of clinical evidence of liver involvement. Thus, ultrasound diagnosed periportal fibrosis 3.1 times more frequently than clinical examination did. CONCLUSIONS: Although clinical examination is important in evaluating morbidity due to Manson's schistosomiasis in endemic areas, ultrasound is more accurate in diagnosing liver involvement and periportal fibrosis.

Prevalence of intestinal parasites in preschool children in the region of Uberlândia, State of Minas Gerais, Brazil

INTRODUCTION: Children are an important high-risk group for helminth and protozoa infections. Daycare centers are environments where children have proven to be more susceptible to acquiring intestinal parasites. Thus, the purpose of this study was to verify the prevalence of intestinal parasites in children who attended the two daycare centers maintained by the local government of Uberlândia, State of Minas Gerais, Brazil. METHODS: Fecal samples were collected from 133 children (73 children at the Public Preschool for Early Childhood Education, PPECE A, and 60 at the PPECE B) following identification according to sex and age and agreement to participate by parents or guardians who signed the free, informed consent form. The samples were examined by the Lutz method. RESULTS: Coproparasitological tests performed on 133 children showed that 29.3% of them were parasitized for enteroparasites or commensals, 6.7% of the children presented polyparasitism. Among the protozoa, Giardia lamblia were the most prevalent and Hymenolepis nana were the most frequent among the helminths. CONCLUSIONS: Thus, analysis of the results showed that intestinal parasites still represent a public health problem, especially among children and in areas where the socioeconomic and educational conditions are less favorable.

Segurança do doente e boas práticas de consentimento esclarecido na realização de exames de tomografia computorizada

RESUMO - O presente trabalho pretende centrar-se no estudo da Segurança do Doente e das boas práticas de Consentimento Esclarecido na realização de exames de Tomografia Computorizada. Nos dias de hoje, a assinatura do documento de Consentimento Esclarecido tem-se mostrado um ato banal, sem a merecida atenção que entidades de saúde, Médicos e Técnicos de Radiologia lhe deviam conceder, uma vez que os Eventos Adversos, aquando da realização de uma TC com Meio de Contraste, poderão ser vários e complicados; por outro lado, o doente muitas vezes não está preparado nem devidamente informado sobre os seus efeitos e as medidas necessárias que deverão ser acionadas para os combater. A necessidade da veiculação de uma informação capaz, de uma elucidação total para o doente pôr em prática a sua autonomia, fruto da consciência que tem dos factos, revela-se fundamental, mas para que tal aconteça é urgente ultrapassar obstáculos respeitantes às práticas profissionais de entidades de saúde, Médicos e Técnicos de Radiologia, assim como aspetos sociais, linguísticos, idade, vulnerabilidade individual, entre outros. Neste contexto, a apresentação de boas práticas de Consentimento Esclarecido revela-se de extrema importância para o desenvolvimento desta dissertação. Para consubstanciar as ideias a desenvolver, para além da pesquisa bibliográfica, revelou-se importante a recolha de dados através de uma entrevista e de um inquérito a elementos que participam neste processo, nomeadamente, doentes, Médicos e Técnicos de Radiologia e, posteriormente, uma análise dos conteúdos dos resultados obtidos e a sua integração nos princípios teóricos do estudo.

Contributo da curva de débito-volume na detecção da obstrução da via aérea central

RESUMO: Introdução: A obstrução da via aérea central (OVAC) refere-se a um processo patológico que conduz a limitação do fluxo de ar ao nível do espaço glótico e subglótico, traqueia e brônquios principais. O seu correcto diagnóstico e tratamento constituem um território de interesse e preocupação para os profissionais de saúde, e requerem um profundo conhecimento da sua etiologia, fisiologia, diagnóstico e opções terapêuticas dado o potencial em originar significativa morbilidade e mortalidade. A avaliação da OVAC abrange múltiplas vertentes, entre as quais se salienta o componente clínico (sinais e sintomas), a repercussão fisiopatológica (função respiratória) e o estudo imagiológico (TC do tórax e broncoscopia). A compilação destes dados associada à etiologia, constituem factores importantes para estabelecer o prognóstico, determinar a necessidade de tratamento ou delinear uma futura intervenção terapêutica. A broncoscopia é o Gold Standard de avaliação desta condição, mas desde há cerca de 40 anos a curva de débito-volume constitui uma ferramenta não invasiva de detecção de OVAC. Apesar deste método ser utilizado até os nossos dias, poucos têm sido os estudos com o objectivo de verificar a sensibilidade e especificidade da curva de débito-volume na detecção de OVAC, bem como averiguar a relação entre as alterações morfológicas e quantitativas da mesma com a localização, o tipo e o grau da obstrução. Material e Métodos: Entre 1 de Novembro de 2009 e 30 de Abril de 2010, os doentes com indicação para a realização de broncoscopia diagnóstica ou terapêutica na Unidade de Técnicas Invasivas Pneumológicas (UTIP) do Centro Hospitalar Lisboa Norte – Hospital Pulido Valente (CHLN – HPV) foram seleccionados de forma consecutiva de acordo com os critérios de inclusão e exclusão. As avaliações (broncoscopia, curva de débito-volume e avaliação da dispneia) realizaram-se com um intervalo de tempo máximo de sete dias. A broncoscopia flexível foi realizada segundo as normas da British Thoracic Society e as curvas de débito-volume segundo as normas da ATS/ERS TaskForce 2005. Para a avaliação da dispneia recorreu-se à escala de dispneia MRC (Medical Research Council). Um painel de peritos realizou a avaliação da morfologia da curva de débito-volume (sugestiva ou não de OVAC) e um elemento independente a verificação dos critérios quantitativos e morfológicos (variáveis intra e extratorácica e fixa) da curva. O estudo foi aprovado pela Comissão de Ética para a Saúde do CHLN e todos os doentes assinaram um consentimento informado de participação. Resultados: Estudaram-se 82 doentes, 36 (44%) dos quais com OVAC. A predominância foi do género masculino, em relação ao feminino. A sensibilidade e especificidade dos critérios quantitativos da curva de débito-volume na detecção de OVAC foi de 91.3% e 88.9% respectivamente. Quando se utilizaram os critérios morfológicos da curva de débito-volume os valores foram de 93.5% e 30.6%. A agregação dos critérios morfológicos e quantitativos permitiu alcançar uma sensibilidade de 95.7% e especificidade de 86.1%. Nesta amostra, o critério quantitativo com maior ocorrência foi o FEF50/FIF50≥1 (83% dos doentes com OVAC). Este mostrou relacionar-se com todas as localizações de obstrução excepto o terço médio da traqueia. Mostrou, ainda, ter uma relação forte e positiva com o grau e tipo de obstrução (intra e extraluminal). O segundo foi o FEV1/PEF≥8, presente em 36% dos casos de OVAC. Relacionou-se com as obstruções no terço inferior da traqueia e brônquio principal direito (BPD). Também apresentou relação forte e positiva com o grau de obstrução e com os tipos de obstrução anteriormente descritos. Quanto à sintomatologia foi possível associar o grau de obstrução com o de dispneia e a presença de estridor com o grau e localização da obstrução na traqueia. Conclusões: Os resultados deste estudo demonstram que os critérios quantitativos da curva de débito-volume têm elevada sensibilidade e especificidade na detecção de OVAC. O critério FEV50/FIF50≥1 tem um bom poder discriminativo na detecção dessa condição, tendo sido relacionado com a localização, o grau e o tipo de obstrução. O critério FEV1/PEF≥8, embora com menor poder discriminativo, também se relaciona com o grau, a localização e o tipo de obstrução. A morfologia da curva tem uma boa sensibilidade mas baixa especificidade na detecção de OVAC, mas a agregação entre os critérios morfológicos e quantitativos aumenta a sensibilidade e especificidade. A dispneia e o estridor foram relacionados com o grau de obstrução e o último com a localização ao nível da traqueia.-------------ABSTRACT: Introduction: Central airway obstruction (CAO) refers to a pathological process that leads to restriction of airflow at the level of the glottis and subglottis, trachea and main bronchi. It’s proper diagnosis and treatment is an area of interest and concern to health professionals, and requires a deep knowledge of its etiology, physiology, diagnosis and treatment options, concerning the potential to cause significant morbidity and mortality. The evaluation of CAO covers multiple aspects: the clinical component (signs and symptoms), the pathophysiological effect (lung function) and the imaging study (bronchoscopy and chest CT). The compilation of this data associated with the etiology, are important for establishing prognosis, determine the need for treatment or outline a future therapeutic intervention. Bronchoscopy is the gold standard for evaluating this condition, but for the last 40 years the flow-volume loop has been used as a noninvasive tool for detecting CAO. Although this method is still in use, only few studies were made in order to verify its sensitivity and specificity in detecting CAO, and investigate the relation between morphological and quantitative changes of the curve to location, type and degree of obstruction. Methods: Between 1st November 2009 and 30th April 2010, patients with indication to perform diagnostic or therapeutic bronchoscopy in Interventional Pulmonology Unit - Hospital Pulido Valente (CHLN - HPV), were selected consecutively according to the inclusion and exclusion criteria. All assessments (bronchoscopy, flow-volume loop and dyspnea) were carried out within a period of seven days. The flexible bronchoscopy was performed according to the standards of the British Thoracic Society and the flow-volume loops in accordance with the standards of the ATS / ERS Taskforce 2005. For the evaluation of dyspnea was used to MRC dyspnea scale (Medical Research Council). A panel of experts evaluated the morphology of flow-volume loop (suggestive or non-suggestive of CAO) and an independent element established the quantitative criteria and morphological (intra and extrathoracic variables and fixed) of the curve. This study was approved by the Ethics Committee for Health CHLN and all the patients signed an informed consent to participate. Results: We’ve studied 82 patients, 36 (44%) of those with CAO. The majority of the patients were males, compared to females. The sensitivity and specificity of the quantitative criteria of the flow-volume curve in detecting CAO was 91.3% and 88.9% respectively. When we used the morphological criteria of flow-volume loop these values were 93.5% and 30.6%. The combination of quantitative and morphological criteria produced values of 95.7% sensitivity and 86.1% specificity. FEF50/FIF50≥1 was the most representative quantitative criterion (83% of patients with CAO) and it was correlated with all sites of obstruction except in the middle third of the trachea. It has shown a strong and positive association with the degree and type of obstruction (intra and extraluminal). The second was the FEV1/PEF ≥ 8, present in 36% of cases of CAO. It could be correlated with the obstruction in the lower third of the trachea and right main bronchus. It also showed a strong positive relation with the degree and types of obstruction described above. Regarding symptoms, we found a link between the degree of obstruction and dyspnea. The presence of stridor was correlated with the location and the degree of obstruction in the trachea. Conclusion: The results of this study demonstrate that the quantitative criteria of the flow-volume loop have a high sensitivity and specificity in detecting CAO. The criterion FEV50/FIF50 ≥ 1 has a good discriminative power to detect this condition and was related to the location, degree and type of obstruction. The criterion FEV1/PEF ≥ 8, although with a weaker discriminative power, also relates to the degree, location and type of obstruction. The morphology of the curve has a good sensitivity but low specificity in detecting CAO although the combination between the morphological and quantitative criteria increases sensitivity and specificity. Dyspnea and stridor were related to the degree of obstruction and the last one with its location in the trachea.

Plasmodium falciparum infection in pregnant women attending antenatal care in Luanda, Angola

INTRODUCTION: Malaria during pregnancy remains a serious public health problem. The aim of this study was to establish the prevalence and possible risk factors for malaria in pregnant women attending antenatal care at Augusto Ngangula Specialized General Hospital in Luanda, Angola. METHODS: Pregnant women (679 total) who attended antenatal care from April to September 2008 were included in the study after signing informed consent. For each participant, the social-demographic profile and malaria and obstetric histories were investigated via a questionnaire. Diagnosis was made by optic microscopy, and hemoglobin concentration measured. The associations between age, parity, gestational age, residence, schooling, malaria during gravity, anemia and treatment with incidence of Plasmodium falciparum infection were analyzed through logistic regression. RESULTS: During the period of study, 74 (10.9%) out of 679 women were infected by P. falciparum. The average concentration of hemoglobin was 11.1 ± 0.07g/dL, and there were significant associations between the history of malaria during pregnancy, P. falciparum infection (p<0.01) and anemia at the time of observation (p<0.001). CONCLUSIONS: Previous history of malaria during pregnancy represents a risk factor for current infection and anemia was an important complication associated with malaria, even in women who were treated with sulfadoxine-pyrimethamine during pregnancy.

Intervenção da fisiopetarpia em indivíduos com osteoartrose do joelho: características da prática clínica e resultados obtidos em contexto de prática convencionada

RESUMO: Introdução: A osteoartrose do joelho em particular constitui uma das maiores causas de incapacidades no dia-a-dia, morbilidade e aumento dos custos de saúde na população, na medida em que é uma condição que quando sintomática progride para um padrão que incluí dor articular, perda de força, incapacidade para a marcha e redução da aptidão física. A sua prevalência aumenta com a idade, 7% entre pessoas dos 65-70 anos, e 11,2% para aqueles com 80 anos ou mais, pouco variando entre os estudos existentes. Um recente estudo da Organização Mundial da Saúde (OMS) refere que a osteoartrose é a quarta causa mais importante de incapacidade entre as mulheres e a oitava entre os homens. Objetivo do estudo: Descrever a intervenção da fisioterapia em contexto de prática clínica convencionada e os resultados obtidos em indivíduos com OA, ao nível da intensidade da dor, capacidade funcional e perceção global de melhoria. Desenho Metodológico: Trata-se de um Estudo de coorte prospetivo onde foram incluídos indivíduos de ambos os géneros, entre os 60 e os 80 anos, com osteoartrose do joelho referenciada clinicamente. Após o consentimento informado, os pacientes foram, avaliados em quatro momentos: num primeiro momento (T0), antes de iniciarem o tratamento; (T1) após 4 semanas do início do tratamento; (T2) coincidente com o final do tratamento; e (T3) 3 meses após o início do tratamento. Foi utilizado um Questionário de Caracterização Sócio-Demográfica e Clínica, a Escala numérica da dor – END, o questionário KOOS (Knee Injury and Osteoarthritis Outcome Score) e a versão portuguesa da Patient Global Impression Change (PGIC-PT). A base de seleção dos indivíduos foi realizada numa clínica convencionada do Algarve. Resultados: Foi observado um aumento significativo em todos os outcomes avaliados pelo KOOS, END e PGIC num período até 3 meses após a intervenção. Na avaliação da END em T3 o valor da média foi de 1,63(±0,71). Para o KOOS nas subescalas Sintomas foi de 87,60(±5,86), Dor 85,71(±3,99), AVD 78,23(±3,48), ADL 67,71(±7,16), QV 80,71(±9,14), para a PGIC-AVD 5,29(±0,57), PGIC-DOR 5,97(±0,61). Os resultados obtidos pelo teste de Friedman, revelaram um valor de p<0,005. Assim, a melhoria da incapacidade funcional reportada pelos participantes neste grupo é estatisticamente diferente, e de forma significativa nos diferentes momentos de recolha de dados, durante e após o tratamento (X2 (3)=208,862, p<0,005)/ (X2(3)=205,041, p<0,005). Por fim os valores do somatório dos participantes, que estão inseridos em no grupo dos “Bons Resultados”( ≥5) foi de 27,14% em T0 passando para 100,00% em T3, enquanto que o grupo dos “Maus Resultados”(<5) foi de 72,86% em T0 e 100% em T3. Conclusão: Os resultados do presente estudo sugerem que a intervenção da Fisioterapia efetuadas em clínicas convencionadas nos casos da Osteoartrose do joelho são efetivas na redução significativa dos níveis de dor e incapacidade funcional e na Perceção global de melhoria em pacientes com Osteoartrose do joelho. ---------- ABSTRACT: Introduction: Osteoarthritis of the knee in particular is a major cause of disabilities in their day-to-day morbidity and increased healthcare costs in the population, in that it is a disease that when symptomatic progresses to a pattern that included joint pain, strength loss, inability to walk and reduction of physical fitness. It is referred as a risk factor for falls and fractures. Its prevalence increases with age, 7% of people between 65-70 years, and 11.2% for those aged 80 or more, ranging from some existing studies. A recent study by the World Health Organization (WHO) reports that osteoarthritis is the fourth leading cause of disability among women and eighth among men. Objective: To describe the characteristics and the outcomes of the physiotherapy practice in patients with knee osteoarthritis. Methodology: A prospective cohort study, with 70 individuals, aged between 60 and 80 years with the diagnosis of knee osteoarthritis and referred to physiotherapy treatment, was carried out. After informed consent, patients were evaluated in four different moments: at baseline (T0), before starting treatment; 4 weeks after starting their treatment (T1); 8 weeks after starting their treatment (T2); and in a 3 months follow-up (T3). Patients were assessed for their socio-demographic and clinical characteristics, pain intensity (using the numeric pain rating scale- NRS), disability (using the Knee Injury and Osteoarthritis Outcome Score), and for their global impression of change (using the Portuguese version of the Patient Glogal Impression of Change scale). Results: The findings of this study indicate a significant increase in all outcomes assessed (pain, disability and global impression of change), during and after the physiotherapy treatment. At T3, the average value for the NRS was 1.63 (± 0.71). For KOOS in the symptoms subscales was 87.60 (± 5.86), pain 85.71 (± 3.99), ADL 78.23 (± 3.48), ADL 67.71 (± 7.16), QV 80.71 (± 9.14) for the PGIC-AVD 5.29 (± 0.57), PGIC-PAIN 5.97 (± 0.61). The results obtained though the Friedman test revealed a p-value <0.005. Thus, the improvement of functional capacity reported by participants in the group was statistically different at the different moments of data collection, during and after treatment (X 2 (3) = 208.862, p <0.005) / (X 2 (3) = 205.041, p <0.005). Conclusion: The results of this study show that the physiotherapy treatments made on agreed clinics in cases of osteoarthritis of the knee, are effective in significant reduction in the levels of pain and disability and in perception of overall improvement perception in patients with osteoarthritis of the Knee.

Prevalence and risk factors for Toxoplasma gondii infection among pregnant and postpartum women attended at public healthcare facilities in the City of Niterói, State of Rio de Janeiro, Brazil

IntroductionTo determine the prevalence of immunoglobulin G (IgG) and immunoglobulin M (IgM) anti-Toxoplasma gondii antibodies among pregnant and postpartum women attended within the public healthcare system in Niterói, State of Rio de Janeiro, and to detect possible exposure factors associated with T. gondii infection in this population.MethodsIgM and IgG anti-T. gondii antibodies were investigated in 276 pregnant and 124 postpartum women by using the indirect immunofluorescence (IFAT) and immunoenzymatic assay (ELISA) techniques. The participants were selected by convenience sampling. All these 400 patients filled out a free and informed consent statement, answered an epidemiological questionnaire and were informed about the disease.ResultsAmong the 400 samples analyzed, 234 (58.5%) were reactive to IgG anti-T. gondii antibodies, according to the IFAT and/or ELISA assay. One pregnant woman was found to be reactive to IgM anti-T. gondii antibodies, with an intermediate IgG avidity test. Risk factor analysis showed that seropositivity was significantly associated (p<0.05) with age, contact with cats and presence of rodents at home. Through a logistic regression model, these associations were confirmed for age and contact with cats, while education at least of the high school level was found to be a protective factor.ConclusionsThe prevalence rate of IgG anti-T. gondii antibodies in the City of Niterói was high and the risk factors for infection detected after multivariate analysis were: age over 30 years, contact with cats and education levels lower than university graduate level.

Risk factors for hepatitis C virus transmission in the municipality of Catanduva, State of São Paulo: a case-control study

Introduction Hepatitis C virus (HCV) is primarily transmitted via contact with the blood of infected patients, although the form of contact has not been identified for a significant percentage of carriers. The present study evaluated possible risk factors for HCV transmission in a medium-sized town located in the northwest region of the State of São Paulo. Methods This was a case-control study, with the case group consisting of 190 chronic HCV carriers older than 18 years residing in the municipality of Catanduva. The control group also consisted of 190 individuals with HCV-negative serology. The groups were paired (1:1) for gender, age range (± five years), and place of residence. The same structured questionnaire was applied to all subjects, who gave written informed consent to participate in the study. The data were statistically analyzed using crude and adjusted logistic regression, and the results were expressed as odds ratios with a 95% confidence interval. Results The demographic profiles of the groups indicated a predominance of males (68.9%) and mean ages of 47.1 years (case group) and 47.3 years (control group). After adjusting for conditional regression, the following factors were found to represent risks for HCV: history of sexually transmitted disease (STD) and blood transfusion; accidents with syringes and/or needles; tattoos; and the use of non-injectable drugs and injectable medications. Conclusions The transmission of HCV via the blood route has been well characterized. Other forms of contact with human blood and/or secretions are likely to transmit the virus, although with a lower frequency of occurrence.

Implementation of WHO Quality Rights assessment in Kabul Mental Health Hospital

RESUMO: Objetivo Avaliar a qualidade dos serviços de saúde mental e a situação dos direitos humanos no Hospital de Saúde Mental de Kabul (KMHH) e fornecer recomendações para o desenvolvimento de um plano de melhoria, actualização e revisão da Política, Estratégia e Plano Nacionais de Saúde Mental,. Métodos A avaliação foi realizada em Janeiro de 2015 no KMHH e na Burn Ward do Hospital Terciário de Isteqlal por uma equipa multidisciplinar usando Qualidade Direitos Tool Kit da OMS. Antes da avaliação, o protocolo foi aprovado pelo Institutional Review Board e obtido o consentimento informado de cada entrevistado. Realizaram-se entrevistas com 16 utentes do serviço, 17 funcionários do hospital e 7 familiares, além da revisão de documentos e da observação das unidades de internamento do KMHH e das interações interpessoais entre funcionários do hospital e utentes do serviço. A comissão de avaliação reviu também a documentação e observou a Unidade de Queimados do Hospital Terciário de Isteqlal, a fim de avaliar e comparar a paridade entre as duas instalações. Após a avaliação, todos os membros da comissão se reuniram e puseram em conjunto todas as conclusões num relatório final. Resultados Encontrámos algumas lacunas graves no nível de prestação de serviços e no respeito pelos direitos humanos dos utentes dos serviços e dos seus familiares. Uma série de políticas, diretrizes e procedimentos relacionados com os direitos humanos dos pacientes estavam ausentes. O ambiente terapêutico e o padrão de vida eram inadequados, existia má qualidade do atendimento e dos serviços prestados, os utilizadores enfrentavam violações do direito ao exercício da capacidade legal e da liberdade pessoal, eram quimica e fisicamente (uso de correntes) contidos e expostos a abusos verbais, físicos e emocionais, e havia grande ênfase no tratamento institucional. Todos estes aspectos foram considerados como extensa violação dos direitos humanos dos utentes de serviço do KMHH. Conclusão Os serviços disponíveis para utentes dos serviços de saúde mental apresentam alguns problemas devido à desconfiança e falta de consciencialização sobre os direitos das pessoas com doença mental e precisam ser alterados de forma positiva. A Lei de Saúde Mental existente difere muito das recomendações da Convenção sobre os Direitos das Pessoas com Incapacidades (CRPD) e requer revisão e adaptação de acordo com esta Convenção. -------------------------------- ABSTRACT: Objective To assess the quality of mental health services and human rights condition in the Kabul Mental Health Hospital (KMHH) and provide recommendations for development of an improvement plan and to update and revise the National Mental Health Policy, Strategy and Plan. Methods The assessment was conducted in January 2015 in the KMHH and the Burn Ward of Isteqlal Tertiary Hospital by a multidisciplinary team using WHO Quality Rights Tool Kit. Before the assessment, Institutional Review Board approval and informed consent from each interviewee were obtained. Interviews were conducted with 16 service users, 17 hospital staffs and 7 family members in addition to documents review and observation of inpatient units of KMHH plus interpersonal interactions between hospital staff and service users. The assessment committee reviewed the documentation and observed the Burn Ward of Isteqlal Tertiary hospital in order to measure and compare parity between the two facilities. After the assessment, all committee members gathered and synchronized all findings into a final report. Results There were some serious gaps on service provision level and respecting human rights of service users and their family members. A series of policies, guidelines and procedures related to patients’ human rights were absent. Inadequate treatment environment and standard of living, poor quality of care and services, violations of the right to exercise legal capacity and personal liberty, being chemically and physically (e.g. chain) restrained, being exposed to verbal, physical and emotional abuse, and emphasis on institutional treatment were all extensive human rights violation that service users were experiencing in KMHH. Conclusion The available services for mental health service users are questionable due to mistrust and lack of awareness about rights of people with disabilities and need to be positively changed. Existing Mental Health Act has a large number of disparities with the CRPD and requires revision and adaptation in accordance to CRPD.

Antecipação e experiência emocional de parto

Este estudo tem como objectivo geral analisar a forma como as mulheres por um lado antecipam e, por outro lado, experienciam emocionalmente o parto do seu primeiro filho. Foi também nosso interesse averiguar a relação entre a antecipação e a experiência real de parto. Para o efeito, 197 grávidas primíparas, com idades compreendidas entre 15 e 39 anos e utentes da Consulta Externa de Obstetrícia da Maternidade Júlio Dinis (Porto) participaram no estudo. Após consentimento informado as participantes preencheram um Questionário Socio-demográfico e o Questionário de Antecipação do Parto (QAP, Costa, Figueiredo, Pacheco, Marques, & Pais, 2005) no 2º trimestre de gravidez. Na primeira semana após o parto foram novamente contactadas as participantes na Unidade de Internamento na Maternidade de Júlio Dinis no sentido de responderem ao Questionário de Experiência e Satisfação com o Parto (QESP, Costa, Figueiredo, Pacheco, Marques, & Pais, 2005). Os resultados mostram que o planeamento do parto parece ser benéfico para algumas mulheres em termos do medo, dor e preocupação em relação ao bebé durante o parto. Deste modo, a implementação de medidas que promovam a informação, suporte emocional e envolvimento nas tomadas de decisão por parte dos serviços de saúde materno-infantis poderiam constituir uma mais-valia para o melhoramento das experiências dos pais.

Dipyridamole stress myocardial perfusion by computed tomography in patients with left bundle branch block

Abstract Background: Functional tests have limited accuracy for identifying myocardial ischemia in patients with left bundle branch block (LBBB). Objective: To assess the diagnostic accuracy of dipyridamole-stress myocardial computed tomography perfusion (CTP) by 320-detector CT in patients with LBBB using invasive quantitative coronary angiography (QCA) (stenosis ≥ 70%) as reference; to investigate the advantage of adding CTP to coronary computed tomography angiography (CTA) and compare the results with those of single photon emission computed tomography (SPECT) myocardial perfusion scintigraphy. Methods: Thirty patients with LBBB who had undergone SPECT for the investigation of coronary artery disease were referred for stress tomography. Independent examiners performed per-patient and per-coronary territory assessments. All patients gave written informed consent to participate in the study that was approved by the institution’s ethics committee. Results: The patients’ mean age was 62 ± 10 years. The mean dose of radiation for the tomography protocol was 9.3 ± 4.6 mSv. With regard to CTP, the per-patient values for sensitivity, specificity, positive and negative predictive values, and accuracy were 86%, 81%, 80%, 87%, and 83%, respectively (p = 0.001). The per-territory values were 63%, 86%, 65%, 84%, and 79%, respectively (p < 0.001). In both analyses, the addition of CTP to CTA achieved higher diagnostic accuracy for detecting myocardial ischemia than SPECT (p < 0.001). Conclusion: The use of the stress tomography protocol is feasible and has good diagnostic accuracy for assessing myocardial ischemia in patients with LBBB.

Subclinical femoral neuropathy after anterior cruciate ligament reconstruction

Background and aim of the study: Patients with anterior cruciate ligament (ACL) reconstruction and femoral catheter analgesia may develop quadriceps amyotrophy. We aimed to determine whether this amyotrophy might be related to a femoral neuropathy. Material and method: After Ethical Committee approval and patients' written informed consent, 17 patients ASA I and II scheduled to undergo ACL reconstruction were recruited. An electromyography (EMG) was performed before the operation in order to exclude a femoral neuropathy. A femoral nerve catheter was inserted before the surgery with the aid of a nerve stimulator, and 20 ml of 0.5% ropivacaine was injected. The operation was done under spinal or general anaesthesia. Postoperative analgesia was provided with 0.2% ropivacaine for 72 hours, in association with oxycodone, paracetamol and ibuprofen. A second EMG was performed 4 weeks after the ACL repair. A femoral neuropathy was defined as a reduction of the surface of the motor response of more than 20%, compared to the first EMG. A third EMG was performed at 6 months if a neuropathy was present. Results: Mean age of this group of patients was 27 years old (range 18-38 y.). Among the 17 patients, 4 developed a transient femoral neuropathy (incidence of 24%) without clinical complain. Conclusion: In this study, the incidence of subclinical femoral neuropathy after ACL reconstruction is high. This lesion may be caused by the femoral catheter (mechanical damage, toxicity of local anaesthesia) or by the Tourniquet. Further studies are needed to investigate the incidence of subclinical neuropathy, according to the type of analgesia (epidural analgesia, PCA) and surgery.
