Enteroparasitosis and their ethnographic relationship to food handlers in a tourist and economic center in Paraná, Southern Brazil

This study reports on the occurrence of enteroparasites based on data from an ethnographic study of food handlers in the city of Cascavel, Paraná, Brazil. Fecal material from 343 food handlers of both sexes, between 14 and 75 years of age, was analyzed using Lutz, modified Ritchie and Ziehl-Neelsen techniques. Ethnographic relationships were investigated by means of specific questionnaires. Positive fecal samples were found for 131 (38.2%) handlers. Endolimax nana (67.9%) was the predominant species, followed by Entamoeba coli (35.9%), Blastocystis hominis (28.2%), Entamoeba histolytica/dispar (10.1%) and Giardia duodenalis (8.4%). Protozoan infections were more common than helminth infections (p = 0.00). The positive results for some parasites were associated with the male sex, professional category, and the performance of other activities (p < 0.05). The high overall occurrence of enteroparasites found indicates improper hygiene and sanitation conditions. Effective educational measures should be implemented to prevent the transfer of pathogenic organisms to food via handling.

A criação de valor no mercado da saúde enquanto fator diferenciador para a negociação de preços e competitividade em contexto de crise mundial

Numa altura em que o setor da saúde é apontado como uma área crítica de gastos, nunca foi tão pertinente, pela falta de verbas, refletir e discutir o formato de contratação e de gestão dos cuidados de saúde. A sua fundamentação em custo, volume ou diferenciação, bem como, os indicadores que refletem o investimento, a eficiência e eficácia dos cuidados. Pretendeu-se como objetivo principal estudar a criação de valor no mercado da saúde enquanto fator diferenciador para a negociação de preços e competitividade em contexto de crise económica. Com vista a alcançar este objetivo, procedeu-se à revisão dos modelos teóricos, recorrendo a pesquisa bibliográfica. Procedeu-se também à comparação dos resultados operacionais de uma empresa enquanto prestadora de serviços de oxigenoterapia ao domicílio, tendo por base duas estratégias diferentes: redução direta de preços ou manutenção de preços com criação de valor para o cliente. Tendo em vista as duas estratégias, foram elaboradas duas propostas e posteriormente apresentadas para avaliação e votação on-line por um grupo oito gestores hospitalares. O valor em cuidados de saúde é visível nos benefícios clínicos alcançados pelo dinheiro investido. A estrutura dos atuais sistemas de saúde apenas reconhece redução de gastos, fontes de receita, volume de cuidados, sem orientação para a valorização dos resultados clínicos. Os prestadores deviam competir pela focalização na obtenção de melhores resultados clínicos, pois deve ser a essa a preocupação central dos serviços médicos. Uma boa gestão pode levar a que numa negociação de contratos, uma proposta baseada em valor possa garantir a manutenção dos preços.

Hidrossalpinge e Outras Causas de Factor Tubário Efeito Deletério do Hidrossalpinge?

Introdução: A Técnica de fertilização in vitro-transferência embrionária (FIV-TE) foi desenvolvida para permitir a gravidez em mulheres com patologia tubária. Inúmeros artigos foram publicados referindo que no grupo de Infertilidade Feminina por Factor Tubário isolado (FTi), o sub-grupo de Hidrossalpinge (HS), apresentava piores resultados nos ciclos FIV-TE. Material e Métodos: Estudo retrospectivo de 99 ciclos FIV-TE efectuados em 88 mulheres com FTi entre Janeiro de 1997 e Dezembro de 1999, na Unidade de Medicina da Reprodução da Maternidade Dr. Alfredo da Costa (MAC). O objectivo foi comparar as diferentes taxas de gravidez entre o subgrupo de Hidrossalpinge (n=28) e o grupo de FTi sem hidrossalpinge (n=71). Resultados: A análise estatística entre o grupo HS e o grupo de Fti sem HS relativamente aos parâmetros do protocolo FIV foi estatisticamente não significativa. Discussão: Um grande número de estudos na literatura confirmam o efeito negativo do HS nos resultados da técnica FIV-TE, relativamente às outras causas de factor tubário, excepto os estudos de Sharara et al (1996) e Bazar et al (1995). Provavelmente as diferentes técnicas para o diagnóstico do HS resultam em diferentes percentagens de diagnóstico da patologia, interferindo nos resultados finais. Conclusão: Na população em estudo na MAC o efeito deletério do HS não demonstrou significado estatístico. No entanto, em valor absoluto a taxa de gravidez é discretamente inferior.

Fiscal decentralisation and economic theory

There is no complete overview or discussion of the literature of the economics of federalism and fiscal decentralization, even though scholarly interest in the topic has been increasing significantly over recent years. This paper provides a general, brief but comprehensive overview of the main insights from the literature on fiscal federalism and decentralization. In doing so, literature on fiscal federalism and decentralization is grouped into two main approaches: “first generation of theories” and “second generation of theories”.

Deficiência de Factor C3 – Um Caso Clínico

O sistema do complemento é um componente essencial do sistema imunitário inato, pelo que as deficiências de proteínas da sua complexa cascata podem ter consequências mais ou menos graves, de acordo com a importância do factor afectado. As complicações mais usuais das deficiências do complemento são infecções recorrentes a bactérias encapsuladas e distúrbios autoimunes. Os autores apresentam um caso clínico de deficiência do factor C3, situação extremamente rara, discutindo a fisiopatologia, apresentação clínica, investigação laboratorial e abordagem terapêutica.

Acquired-Transient Factor X Deficiency in a Teenager with Extensive Burns

Acquired factor X deficiency is an extremely rare situation. It has shown to be associated with systemic amyloidosis, respiratory mycoplasma infection, factor X inhibitors, antiphospholipid antibodies, vitamin K defi ciency/liver disease as well as the use of certain medications (meropenem, valproic acid). The pathogenesis and transient nature of this deficit remain poorly understood. The authors describe the case of a teenager hospitalised for extensive burns that developed active bleeding after removal of central venous catheter. He was diagnosed with transient factor X deficiency. Normalisation of coagulation status and factor X levels occurred spontaneously 10 days after the bleeding episode.

Factor V Leiden and Prothrombin G20210A in Portuguese Women with Recurrent Miscarriage: Is it Worthwhile to Investigate?

OBJECTIVE: To compare the prevalence of factor V Leiden (FVL) and prothrombin (PT) G20210A mutations in Portuguese women with unexplained recurrent miscarriage (RM) and a control group of parous women. MATERIALS AND METHODS: FVL and PT G20210A analysis were carried out in 100 women with three or more consecutive miscarriages and 100 controls with no history of pregnancy losses. Secondary analysis was made regarding gestational age at miscarriage (embryonic and fetal losses). RESULTS: Overall, the prevalence of FVL and PT G20210A was similar in women with RM (5 and 3%) compared with controls (5 and 1%) OR 1.36 (CI 95% 0.45-4.08). In RM embryonic subgroup, PT G20210A was observed in 1.3% of women and FVL prevalence (2.6%) was inclusively lesser than that of controls. Both polymorphisms were more prevalent in women with fetal losses than in controls, although statistical significance was not reached due to the small size of the >10 weeks' subgroup. CONCLUSION: These data indicate that neither FVL nor PT G20210A is associated with RM prior to 10 weeks of gestation. Therefore, its screening is not indicated as an initial approach in Portuguese women with embryonic RM and negative personal thromboembolic history.

Anti-Tumor Necrosis Factor Alpha-Induced Drug Eruptions: One Patient, More Than a Pattern

Background: Tumor necrosis factor alpha (TNFα) antagonists are effective in treating several immune-inflammatory diseases, including psoriasis and inflammatory bowel disease. The paradoxical and unpredictable induction of psoriasis and psoriasiform skin lesions is a recognized adverse event, although of unclear aetiology. However, histological analysis of these eruptions remains insufficient, yet suggesting that some might constitute a new pattern of adverse drug reaction, rather than true psoriasis. Case report: The authors report the case of a 43-year-old woman with severe recalcitrant Crohn disease who started treatment with infliximab. There was also a personal history of mild plaque psoriasis without clinical expression for the past eight years. She developed a heterogeneous cutaneous eruption of psoriasiform morphology with pustules and crusts after the third infliximab infusion. The histopathological diagnosis was of a Sweet-like dermatosis. The patient was successfully treated with cyclosporine in association with both topical corticosteroid and vitamin D3 analogue. Three weeks after switching to adalimumab a new psoriasiform eruption was observed, histologically compatible with a psoriasiform drug eruption. Despite this, and considering the beneficial effect on the inflammatory bowel disease, it was decided to maintain treatment with adalimumab and to treat through with topicals, with progressive control of skin disease. Discussion: Not much is known about the pathogenesis of psoriasiform eruptions induced by biological therapies, but genetic predisposition and Koebner phenomenon may contribute to it. Histopathology can add new facets to the comprehension of psoriasiform reactions. In fact, histopathologic patterns of such skin lesions appear to be varied, in a clear asymmetry with clinical findings. Conclusion: The sequential identification in the same patient of two clinical and histopathologic patterns of drug reaction to TNFα antagonists is rare. Additionally, to the authors’ knowledge, there is only one other description in literature of a TNFα antagonist-induced Sweet-like dermatosis, emphasizing the singularity of this case report.

Analysis of mental health service financial models with a particular emphasis of Ireland

ABSTRACT: Financing is a critical factor in ensuring the optimal development and delivery of a mental health system. The primary method of financing worldwide is tax-based. However many low income countries depend on out-of-pocket payments. There is a report on Irish Health Care funding but none that deals exclusively with mental health care. This paper analyses the various financial models that exist globally with respect to financing the mental health sector, examines the impact of various models on service users, especially in terms of relative ‘financial burden’ and provides a more detailed examination of the current mental health funding situation in Ireland After extensive internet and hardcopy research on the above topics, the findings were analysed and a number of recommendations were reached. Mental health service should be free at the point of delivery to achieve universal coverage. Government tax-based funding or mandatory social insurance with government top-ups, as required, appears the optimal option, although there is no one funding system applicable everywhere. Out-of-pocket funding can create a crippling financial burden for service users. It is important to employ improved revenue collection systems, eliminate waste, provide equitable resource distribution, ring fence mental health funding and cap the number of visits, where necessary. Political, economic, social and cultural factors play a role in funding decisions and this can be clearly seen in the context of the current economic recession in Ireland. Only 33% of the Irish population has access to free public health care and the number health insurance policy holders has dramatically declined, resulting in increased out-of-pocket payments. This approach risks negatively impacting on the social determinants of health, increasing health inequalities and negatively affecting economic productivity. It is therefore important the Irish government examines other options to provide funding for mental health services.
