Visual programming of XSLT from examples

Vishnu is a tool for XSLT visual programming in Eclipse - a popular and extensible integrated development environment. Rather than writing the XSLT transformations, the programmer loads or edits two document instances, a source document and its corresponding target document, and pairs texts between then by drawing lines over the documents. This form of XSLT programming is intended for simple transformations between related document types, such as HTML formatting or conversion among similar formats. Complex XSLT programs involving, for instance, recursive templates or second order transformations are out of the scope of Vishnu. We present the architecture of Vishnu composed by a graphical editor and a programming engine. The editor is an Eclipse plug-in where the programmer loads and edits document examples and pairs their content using graphical primitives. The programming engine receives the data collected by the editor and produces an XSLT program. The design of the engine and the process of creation of an XSLT program from examples are also detailed. It starts with the generation of an initial transformation that maps source document to the target document. This transformation is fed to a rewrite process where each step produces a refined version of the transformation. Finally, the transformation is simplified before being presented to the programmer for further editing.

An engine for generating XSLT from examples

XSLT is a powerful and widely used language for transforming XML documents. However its power and complexity can be overwhelming for novice or infrequent users, many of which simply give up on using this language. On the other hand, many XSLT programs of practical use are simple enough to be automatically inferred from examples of source and target documents. An inferred XSLT program is seldom adequate for production usage but can be used as a skeleton of the final program, or at least as scaffolding in the process of coding it. It should be noted that the authors do not claim that XSLT programs, in general, can be inferred from examples. The aim of Vishnu - the XSLT generator engine described in this paper – is to produce XSLT programs for processing documents similar to the given examples and with enough readability to be easily understood by a programmer not familiar with the language. The architecture of Vishnu is composed by a graphical editor and a programming engine. In this paper we focus on the editor as a GWT web application where the programmer loads and edits document examples and pairs their content using graphical primitives. The programming engine receives the data collected by the editor and produces an XSLT program.

Fulminant hepatitis: a clinical review of 11 years

24 cases of fulminant hepatitis (FH) hospitalized in the Clínica de Doenças Infecciosas e Parasitárias do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo during the period from January 1976 to December 1986 were reviewed from their clinical, epidemiological and laboratorial aspects. 88% of the patients died; 20 patients (83%) presented hemorrhages and, of these, 19 died. Bacterial infections occurred in 14 patients (58%) all of whom died. Ascitis was noted in 3 cases; cerebral edema was present in 16 cases. Maximal ALT levels for each patient during hospitalization ranged widely from 81 to 4,460 UI/l. Thirteen patients presented high creatinine levels (54%). Prothrombin time activity ranged from 2.1% to 67%. Fever was present in 20 cases (83%). Encephalopathy occurred within the first 2 weeks of illness in 72% of the cases. In 7 cases other illnesses were present. The etiology could not be determined in 13 cases. In 3 cases it was due to yellow fever and 6 cases were caused by viruses other than yellow fever. In one case the cause was drug usage and in another case, possibly alcohol. The authors believe that the clinical definition of FH requires further discussion before it is established. In this study FH is a young person's disease. The mortality found was similar to that by other authors. Factors that contributed to death were: hemorrhages and bacterial infection. Factors that worsened the prognosis of hepatitis were: associated illnesses and surgical procedure. The levels of ALT during hospitalization did not correlate well with the severity of the hepatitis. The authors believe that yellow fever should be considered a cause of FH where the clinical picture meets the criteria for such, although its mechanisms of encephalopathy remain obscure. The clinical details of the 3 cases of yellow fever are presented.

Determination du niveau d'anticorps antitetaniques en donneurs de sang au moyen du test ELISA-TÉTANOS (São Paulo, SP, Bresil)

Le test ELISA-TÉTANOS (Biosys, France) a été utilisé pour le titrage des anti-corps tétaniques (sensibilité = 0,0025 UI/ml) en sérums humains de donneurs de sang, 566 hommes et 108 femmes, âges de 18 à 58 ans, moyenne de 29 ans, provenant de São Paulo, SP, Brésil. L'OMS, acceptant seulement la séroneutralisation sur souris (NT), la méthode de référence, pour les études sur la protection contre le tétanos, préconise le titre de 0,01 UI/ml comme minimum protecteur. BOURLEAUD & HUET ont proposé la limite de 0,06 UI/ml quand s'emploie le test ELISA, en attendant à une certaine discordance inévitable entre les méthodes. Parmi les 674 sérums étudiés, 178 (26,41%) n'ont pas présenté d'anticorps (< 0,0025 UI/ml); 413 (61,28%) ont présenté des résultats égaux ou supérieurs à 0,01 UI/ml et en 232 (34,42%) les titres ont été égaux ou supérieurs à 0,06 UI/ml. Le pourcentage d'individus protégés a été inversement proportionnel à 1'âge: environ 50% dans le groupe le plus jeune (hommes de 18 à 35 ans et femmes de 18 à 23 ans) contre environ 10% dans le groupe de plus de 42 ans ont présenté des titres sûrement protecteurs (> 0,06 UI/ml).

Engano na administração de soro-vacinação para raiva. Emprego de esquema improvisado e sua avaliação: apresentação de um caso

Apresentamos registro de caso de paciente agredida por cão que morreu 4 dias depois, e que se apresentou para tratamento 11 dias após o acidente. Foi indicado esquema de soro-vacinação a ser iniciado imediatamente com administração de soro anti-rábico (9ml, correspondente a 40 UI/Kg de peso) e série de 10 doses de vacina aplicadas em dias consecutivos e 3 doses de reforço, com 10 dias de intervalo, conforme normas da Secretaria da Saúde do Estado de São Paulo. Por engano, entretanto, foram aplicadas inicialmente 9 doses de vacina em 3 locais anatômicos diferentes. Verificado o erro de imediato, optamos pela suspensão do tratamento por alguns dias e sua reimplantação completa, o que só foi feito após 8 dias. O seguimento sorológico (pelas provas de soro-neutralização em cultura celular) evidenciou resposta inteiramente satisfatória, superando largamente em níveis, precocidade e duração as recomendações da OMS. A paciente permanecia sadia até o 240º dia após o acidente, quando foi observada pela última vez antes desta publicação.

Evaluacion de la tecnica de contraimmunoelectroforesis para determinar la potencia antigena de las vacunas antirrabicas

El método recomendado por la Organización Mundial de la Salud (OMS) para la prueba de potencia de vacunas antirrábicas como producto final es la prueba NIH. Algunas técnicas in vitro se han propuesto para el control durante el proceso de produción y complementan el ensayo in vivo antes mencionado. Este trabajo presenta los resultados obtenidos cuando se utilizó la técnica de contrainmunoelectroforésis (CIE) para determinar el contenido de antígenos en muestras de 84 y 40 lotes de vacunas antirrábicas producidas en tejido nervioso de cerebro de ratón lactante mediante cultivo de tejidos, respectivamente. La evaluación de las muestras en, y en torno de, las 0.3 UI por ambos métodos muestran que, en la práctica, un título CIE de 1:4 cumpliría con un mínimo de potencia de la prueba NIH. Un bajo grado de variabilidad de la prueba CIE fue observada en nuestro laboratorio cuando dos lotes de vacunas de referencia de trabajo y 7 lotes de vacunas antirrábicas, de diferente origen y actividad, fueron ensayadas en cinco pruebas independientes. Todos los títulos se ubicaron dentro de una dilución doble, lo que es indicativo de su reproducibilidad. Se observó buena sensibilidad para detectar el deterioro del antígeno en el ensayo de degradación térmica, cuando muestras de 3 lotes de vacuna líquida de cerebro de ratón lactante fueron mantenidas a4 y 37ºC cada una, por 28 días. Se evaluaron semanalmente por los ensayos de CIE y NIH. Finalmente, se observó que el ensayo de CIE podría ser utilizado por los productores para estimar el punto final de los procesos de concentración para que se corresponda con un valor antigénico deseado en la prueba de potencia NIH.
