Radiographic features of pulmonary tuberculosis in patients infected by HIV: is there an objective indicator of co-infection?

This study aimed to compare the radiographic characteristics of patients with pulmonary tuberculosis (TB) and human immunodeficiency virus (HIV) infection with those of HIV-negative patients. In all, 275 TB patients attending the outpatients clinics at the University Hospital/UFPE, were studied from January 1997 to March 1999. Thirty nine (14.2%) of them were HIV+, with a higher frequency of males in this group (p=0.044). Seventy-five percent of the HIV+ patients and 19% of the HIV- had a negative tuberculin test (PPD) (p < 0.001). The proportion of positive sputum smears in the two groups was similar. The radiological finding most strongly associated with co-infection was absence of cavitation (p < 0.001). It may therefore be concluded that the lack of cavitation in patients with pulmonary TB may be considered a useful indicator of the need to investigate HIV infection. This approach could contribute to increasing the effectiveness of local health services, by offering appropriate treatment to co-infected patients.

Assessment of hydrogen sulfide removal from biogas using a field scale anoxic biotrickling filter.

Hydrogen sulphide is one of the most toxic and corrosive compound present in swine-derived biogas streams.In this study, afield scale biotrickling filter for the removal of hydrogen sulfide was investigated.A Biofilter packed with supporting biofilm materials was fed continuously with a proprietary nutrient solution and operatedfor over 73days. The system has been operating with a H2S inlet concentrations ranging from 1,000to 3,000 ppm.Significant removal efficiencies >95% was demonstrated. pH of the stock feeding solution decreased from 6.2 to as low as 3.5within couple days.The resulting drop in pH provided circumstantial evidence to support biological H2 Soxidation to sulphuric acid by sulfide-oxidizers. Sulfur precipitation was also observed to occur. The results suggested that H2S removal from biogas stream can be efficiently achieved using portable, low cost and maintenance free biotrickling filters.

Development of population-specific function assessment intrument in Lebanon

RESUMO: Contexto: O funcionamento tem sido reconhecido como um dos principais indicadores de resultados para avaliar se as pessoas beneficiam das intervenções destinadas a melhorar a sua saúde mental. O funcionamento refere-se à forma como um indivíduo consegue responder às suas tarefas e solicitações, dos seus familiares e da sua comunidade, de acordo com os requisitos do local e a cultura em que vive (eg, tarefa de cozinhar e limpar para as mulheres em algumas culturas ). O funcionamento é altamente dependente da cultura - por isso, tem sido recomendado o desenvolvimento de medidas de funcionamento específicas de cada cultura. Desenvolver localmente os instrumentos de medida evita problemas de adequação, associados com a adaptação de instrumentos ocidentais. Embora os instrumentos criados desta forma sejam específicos de um meio cultural, eles são simultaneamente "transculturais", no sentido em que cada um se refere às tarefas mais importantes para a população local . Esta abordagem mostrou-se útil para investigadores e agências de ajuda (eg, ONGs) que trabalham em países não-ocidentais . Este estudo descreve o trabalho da agência International Medical Corps (IMC) na criação e validação de um questionário de funcionamento específico nas dimensões cultura e gênero, no Líbano, destinado a avaliar eventuais melhorias em pessoas que receberam intervenções de para problemas de saúde mental, a nível dos cuidados primários de saúde. Método: O instrumento foi desenvolvido usando um método que é uma alternativa à abordagem existente de adaptação de instrumentos ocidentais a outras culturas e situações; esta abordagem é rápida e exequível, tendo já demonstrado ser útil no desenvolvimento de instrumentos válidos e fidedignos. Inicialmente, foi solicitado que as pessoas identificassem, de uma lista livre, as tarefas mais importantes para cuidar de si próprias, da sua família e da sua comunidade; as tarefas identificadas foram posteriormente usadas como base para um instrumento de avaliação de funcionamento culturalmente válido. A partir daqui, foram desenvolvidos questionários específicos da comunidade em questão, posteriormente testados no terreno nas vertentes da validade (de conteúdo, facial e de constructo) e da fiabilidade (teste-reste e inter-entrevistadores). Resultados. O estudo resultou na criação e validação de um questionário de funcionamento específico de cultura e gênero capaz de medir efectivamente a capacidade de execução de tarefas importantes do quotidiano,como parte da avaliação de resultados levada a cabo por profissionais da CSP previamente treinados na identificação, suporte e encaminhamento de pessoas com problemas de saúde mental no Líbano. Conclusão. Neste trabalho descreve-se o desenvolvimento de um questionário de funcionamento específico de cultura e gênero, orientado para a avaliação de resultados, num contexto mais lato de um sistema abrangente de avaliação e monitorização de um serviço comunitário. --------------ABSTRACT: Background. Functioning has been recognized as one of the most important key outcomes to assess whether people benefit from interventions aimed to improve their mental health. Functioning refers to how well na individual can complete the tasks and demands for themselves, their family, and their community which are required by them depending on the setting and the culture they live in (e.g. task of cooking and cleaning for women in some cultures). Functioning is highly dependent on culture. Therefore, it has been recommended to develop culture-specific measures of function. Developing instruments locally avoids the problems of limited local relevance and appropriateness associate with adapting western instruments. Although each instrument created in this way is culturally bound, they are “cross cultural” in the sense that each refers to the tasks most important to local people. This approach proves useful for both researchers and aid agencies working in non-western countries. This study describes International Medical Corps’ (IMC) work in Lebanon to create and validate a culture and gender specific functioning questionnaire to assess improvements in people who received treatment interventions for mental health problems at the primary health care (PHC) level. Method. The measure was developed using a method that is an alternative to the existing approach of adapting western function instruments to other cultures and situations; an approach which has been demonstrated as rapid, feasible and which can yield valid and reliable instruments. Function was assessed by first asking local people what tasks are important to care for themselves, their family and their community using free listing, then using these tasks as the basis for a culturally valid function assessment instrument. Community specific function questionnaires based on these tasks were then created, and field-tested for validity using content, face and construct validity methods, and also field tested for reliability using inter-rater and test retest reliability methods. Results. The study resulted in the creation and validation of a culture and gender specific functioning questionnaire that would effectively measure the ability to do tasks important to daily existence, as part of assessing client level outcomes where PHC providers were trained in the identification, management and referral of people with mental health problems in Lebanon. Conclusion. The paper describes a successful pilot for developing culture and gender specific functioning questionnaires that evaluate client level outcomes as part of a more comprehensive system for monitoring and evaluation of community based case management supports and services.

Evaluation of intrathecal synthesis of specific IgG antibodies against Toxoplasma gondii in the diagnosis assessment of presumptive toxoplasma encephalitis in aids patients

The diagnosis of neurotoxoplasmosis in patients with acquired immunodeficiency syndrome is mainly based on tomographic or magnetic resonance findings and on the response to specific treatment. We studied 55 patients with AIDS and neurotoxoplasmosis according to these diagnostic criteria (group 1), 37 patients with AIDS and neurological involvement of other etiology (group 2), and 16 anti-HIV-negative individuals with neurological manifestations (group 3). Serum and cerebrospinal fluid were examined for the presence of anti-T. gondii IgG, by indirect immunofluorescence. In 72 of them, the total amounts of these antibodies were determined in order to assess local production of anti-T. gondii antibodies in the central nervous system and to correlate their titers with infection activity in patients with AIDS and neurotoxoplasmosis. IgG titers > 1/64 in cerebrospinal fluid reached 100% specificity for the diagnosis of neurotoxoplasmosis in AIDS. Evidence of local synthesis of these antibodies was detected in 42.8% of patients of group 1, in 29.1% of patients of group 2 and in no patient of group 3. The test showed 70.8% specificity and therefore was not useful in our study for the differential diagnosis of neurotoxoplasmosis in patients with AIDS.
