Triagem para formas atenuadas de mucopolissacaridose em pacientes com problemas ósteo-articulares de etiologia desconhecidaSiqueira, Thabata Caroline da Rocha January 2015 (has links)
Introdução: As mucopolissacaridoses (MPS) são um conjunto de sete doenças genéticas incluídas dentro das Doenças Lisossômicas que por sua vez fazem parte dos Erros Inatos do Metabolismo (EIM). São doenças multissistêmicas que afetam todo o organismo, com variações conforme o tipo de MPS, sendo que algumas delas possuem tratamento específico. Quase todas comprometem, em graus variados, o sistema osteoarticular, e praticamente todos os pacientes apresentam excreção alterada de glicosaminoglicanos (GAGs) na urina. As MPS são doenças raras que podem ser subdiagnosticadas em função do pouco conhecimento dos profissionais de saúde sobre elas, do pouco acesso aos métodos de triagem e diagnóstico e da sua ampla heterogeneidade clínica, podendo ocorrer formas atenuadas nas quais pode ser difícil de levantar a suspeita clínica de MPS. Material e métodos: o presente estudo foi realizado no período de março de 2012 à janeiro de 2014, tendo incluído 55 pacientes atendidos em serviços de Reumatologia e/ou Ortopedia de Porto Alegre, RS, Brasil e que, apresentavam como principal queixa, manifestações articulares sem etiologia definida. Esses pacientes foram inicialmente investigados através da avaliação quantitativa e qualitativa dos GAGs urinários. Resultados e Discussão: entre os 55 casos investigados, em 1 paciente de 15 anos de idade foi observada na análise dos GAGs urinários excreção aumentada e alteração do padrão qualitativo, sendo posteriormente confirmado o diagnóstico de uma forma atenuada de MPS II, a qual não havia sido suspeitada anteriormente. Conclusão: embora a proporção de pacientes identificados com MPS na amostra estudada tenha sido pequena (1/55), este estudo mostra que ocorre subdiagnóstico dessas doenças e que a triagem sistemática pode contribuir para a identificação de pacientes, os quais podem se beneficiar das medidas de tratamento disponíveis. / Introduction: Mucopolysaccharidoses (MPS) are a set of 7genetic diseases including Lysosomal Diseases , which in turn are part of Inborn Errors of Metabolism (IEM). The MPS are multisystemic conditions that affect the entire body, with variations depending on the type, some of which have specific treatment. Almost all affect, in variable degrees, the osteo-articular system, and virtually all patients have abnormal excretion of glycosaminoglycans (GAGs) in urine. The MPS are rare diseases that are being underdiagnosed due to the little knowledge of health professionals about them, the poor access to screening and diagnostic methods and their extensive clinical heterogeneity. Also, attenuated forms may occur in which it may be difficult to raise the clinical suspicion of MPS. Material and Methods: The present study was conducted from March 2012 to January 2014 and included 55 patients from Rheumatology and/or Orthopedics services of Porto Alegre, RS, Brazil and which had, as main complaint, articular manifestations without defined etiology. These patients were screened by quantitative and qualitative assessment of urinary GAGs. Results and Discussion: Among the 55 cases investigated, in 1 patient 15 years of age was observed in the analysis of urinary GAG excretion and increased change in qualitative standard and subsequently confirmed the diagnosis of an attenuated form of MPS II, which had not previously been suspected. Conclusion: Although the proportion of patients with MPS identified in the study sample was small (1/55), this study shows that occurs underdiagnosis of these diseases and that systematic screening can help to identify patients who may benefit from measures treatment available.

Improving the prevention of sexually transmitted infections (STIs) : a study using Chlamydia trachomatis as a model infectionNovak, Daniel January 2006 (has links)
Despite the current preventive strategies sexually transmitted infections (STIs) are rising. This thesis presents a model with the aim of improving the prevention of STIs. Chlamydia being the most common STI in Sweden serves as a model infection. The presented model is based on five performed studies. First we evaluated the feasibility of taking a urine sample at home and sending it with mail for Chlamydia analysis. Postal screening was thereafter analyzed for cost effectiveness estimating the cost per prevented sequel and the prevalence threshold. A population based study of all the 22-year old men in Umeå tested the feasibility of the Internet as a tool in facilitating Chlamydia testing and also attempted to engage men who often have low participation in Chlamydia screening programs. A questionnaire to all 18-year old youths in four northern Swedish cities was analysed concerning condom use. Finally, ordering home a Chlamydia test from the Internet was tested as method for self-selective screening. The studies showed that it was both feasible and acceptable by the population to send in urine samples with mail for Chlamydia analysis. Large-scale postal screening would be cost-effective in a female population if the C. trachomatis prevalence exceeds 5% and cost effective in a male population if the C. trachomatis prevalence exceeds 12.3%. Using the Internet as a tool in Chlamydia testing proved feasible and almost 38% of all the 22-year old men in Umeå participated. Condom usage being the most important STI preventive measure during a sexual intercourse proved to be dependent on more male factors than female factors, where the use of oral contraceptives was the strongest factor associated with non-condom use. Ordering a test on the Internet proved to be a feasible self-selective screening method. Condom use should continuously be promoted to sexually active people especially if oral contraception is used. Success and cost effectiveness in controlling STI transmission is likely to depend on achieving consistent and regular coverage of testing and partner notification among both women and men. The suggested model uses the Internet as a tool in communicating preventive STI information and allowing a self-selective screening, which may be used as an adjunct to regular recruitment in striving for improving the STI prevention. Key words: STI, prevention, Chlamydia, postal screening, cost effective, condom, Internet, self-selective screening.
