Peripheral facial palsy in the past: contributions from Avicenna, Nicolaus Friedreich and Charles Bell

Este estudo apresenta documentos de paralisia facial periférica nas artes plásticas no Egito antigo, Grécia e Roma, Idade Média, Renascimento e também dos últimos 4 séculos. Pensamos que a história da paralisia facial periférica acompanha a história da própria espécie humana. São apresentadas as contribuições de Avicenna e Nicolaus Friedreich, e são mostradas controvérsias sobre a descrição original de Charles Bell.

Treatment of pediatric myelodysplastic syndromes and juvenile myelomonocytic leukemia: the Brazilian experience in the past decade

Background: Therapy strategies for myelodysplastic syndromes (MDS) and juvenile myelomonocytic leukemia (JMML) vary considerably. Objective: To review the treatment of Brazilian children who were diagnosed with MDS or JMML in the past decade and reported to the Brazilian Cooperative Group on Pediatric Myelodysplastic syndromes (BCG-MDS-PED). Results: of 173 children reported to the BCG-MDS-PED from January 1997 to January 2003 with a suspected diagnosis of MDS or JMML, 91 had the diagnosis confirmed after central review of the bone marrow aspirate and biopsy. Information on previous treatments was available for 78 MDS/JMML patients. Treatment varied from different schedules of low-dose (14%) and standard-dose chemotherapy (50%), granulocyte-colony-stimulating factor (G-CSF 7%), interferon (5%), steroids (2%) and erythropoietin (2%) to allogeneic stem-cell transplantation (SCT) (14%). No survival advantage could be demonstrated based on Hasle's classification or based on treatment. Conclusion: This report reflects the current practice in treating Brazilian children with MDS/JMML without specific Cooperative Group guidelines. Treatment modalities were very heterogeneous. The strategies for implementing a national protocol should consider international guidelines and focus on local experience and available resources. (C) 2004 Elsevier Ltd. All rights reserved.

Immunoassays for pesticide analysis in environmental and food matrices

Immunochemical methods have increased considerably in the past years, and many examples of small and large scale studies have demonstrated the reliability of the immunotechniques for control and monitoring gf contaminant residues in different kinds of samples. Application of the immunoassay (IA) methods in pesticide residue control is an area with enormous potential for growth. The most extensively studied IA is the enzyme-linked absorbent assay (ELISA), but several other approaches, that include radioimmunoassay and immunoaffinity chromatography, have been also developed recently. In comparison with classical analytical methods, IA methods offer the possibility of highly sensitive, relatively vapid, and cost-effective measurements. This paper introduces the general IAs used until now, focusing on their use in pesticide analysis, and discussing briefly the effects of interferences from solvent residues or matrix components on the IA performance. Numerous immunochemical methods commonly used for pesticide determination in different samples such as food, crop and environmental samples are presented.

Anti-poverty policies in Brazil: Reviewing the past ten years

This article reviews the main anti-poverty policies implemented in Brazil from the early 1990s to the early 2000s. These include focused and universal policies - such as education and health care - as well as the rural development, a 'middle ground' policy. Though the inter-municipal consortium, a new institutional arrangement gathering municipalities together, has emerged as a promising policy implementation tool, anti-poverty policies have faced implementation difficulties. Lack of coordination between different programs, even within the same policy area, has impaired their effectiveness. As a consequence, compensatory programs, based on monetary transfers to poor families, which face fewer implementation problems, have become the dominant type of anti-poverty policies in Brazil. Despite these shortcomings, a small Brazilian state, Santa Catarina, was able to reduce by 46 percent the number of individuals living in poverty in just ten years. This is a sign that fighting poverty can, after all, be a feasible endeavor. © 2004 IIAS, SAGE Publications (London, Thousand Oaks, CA and New Delhi).

Energy efficiency in Latin America and the Caribbean: Progress and challenges of the past five years. Executive summary

The present document analyses the progress of national programmes and activities associated with the promotion and development of energy efficiency between the years 2008 and 2013 in the 27 Latin American and the Caribbean member countries of the Latin American Energy Organization (OLADE). The new study is based on the original report —prepared by ECLAC and OLADE between July 2008 and July 20091— taking into consideration any progress made over the past four to five years, an interval long enough to justify an update both of the current status of energy efficiency and its prospects, developments and challenges in the Region of Latin America and the Caribbean.
