Abstract: with more than one hundred years of history, the division of labor in dentistry is a process that is affected by distinct and sometimes opposing principles: professional (social) and administrative (technical/economic). the circumstances created by the historical dynamics of these recursively contending principles redefine the possibilities of their operation. in brazil today, the inordinate number of dentistry surgeons in the dentistry field has created anomalies in the professionalization process in brazil, as well as ineffectiveness and unfairness in the rationalization process and expansion of the division of labor (team work) in the public health system (sus), particularly with regards to the basic health care provided by the family health strategy, and the perpetuation of interpretative disputes around normative instruments in the legal system, such as law no. 11,889/2008, which governs the professions of buccal health technician and buccal health assistant. all of these are crucial elements for the future of the organization of the buccal health sector of basic health care, as well as the future disposition of the work force in the epidemiological transition process that is currently underway in the country.

Abstract: the objective of this work was to evaluate the effect of periods of pre-wilting of stargrass [cynodon plectostachyus (k. schum.) pilg.] and tifton 85 bermudagrass (cynodon sp.) on some characteristics of their silage. arandomized design with ten treatments and three replications was used. the treatments were arranged in a 2x5 factorial, two grasses (stargrass and tifton 85) and five periods of pre-wilting of forage (0, 1, 2, 3 and 4 h). the grasses were harvested at 50 days regrowth and stored for 55 days in experimental silos. the pre-wilting caused an increase in dry matter content of forage and silage of both, tifton 85 and stargrass. there was a decrease in the levels of ammonia-n (n-nh3/n-total) of the stargrass silage at a rate of 1.66 percentage unit per hour of pre-wilting, but there was no change in this variable of tifton 85 silage. the tifton 85 silage presented higher dry matter recovery and content of ndf and lower protein content than the silage stargrass. the ph and adf content of the silage were not affected by pre-wilting.

Abstract: Objetivo do estudo: Avaliar o padr o da evolu o dos fluxos e volumes pulmonares dinamicos dos pacientes com fibrose cística (FC), assim como analisar a rela o entre a gravidade do comprometimento ventilatório com a idade, sexo, genótipo e coloniza o pulmonar. Material e método: Na Unidade de Pneumologia Infantil e Servi o de Pneumologia do Hospital de Clínicas de Porto Alegre, foram avaliadas 243 espirometrias de 52 pacientes portadores de FC maiores de quatro anos realizadas no período de 1987 a 1999. Do prontuário médico foram extraídas informa es sobre idade ao diagnóstico, pesquisa genética, coloniza o br nquica e os valores absolutos e percentuais para fluxos e volumes da melhor espirometria de cada ano. Resultados: A idade dos pacientes variou de quatro a 26 anos (média = 13,04 ± 4,82). Dos 52 pacientes, 49 (94%) tiveram pelo menos uma cultura de escarro com P. aeruginosa, 45 (86%) com S. aureus e 13 (25%) com B. cepacia. Na avalia o inicial dos quatro aos seis anos (n = 40), os valores médios da CVF e do VEF1 foram de 114,24% e 112,25%, respectivamente. A média da CVF manteve-se acima do normal até os 18 anos, quando apresentou queda súbita para 67,2% (p = 0,0002). A média do VEF1 atingiu valores abaixo de 80% aos dez anos, estando em 50% aos 18 anos (p < 0,00001). A rela o VEF1/CVF%, índice mais sensível de obstru o, mostrou-se diminuída já na primeira avalia o, sendo 85% entre os quatro e seis anos, com declínio lento progressivo, chegando a 63% aos 18 anos. Os valores médios do FEF50, FEF75 e FMEF inicialmente foram normais (94%, 80% e 90%, respectivamente), mostraram queda maior e mais precoce, estatisticamente significativa, atingindo valores médios aos 18 anos de 37%, 12,5% e 19%, respectivamente. Embora houvesse tendência para fluxos terminais mais baixos para as meninas, as diferen as n o tiveram valor estatístico. Também n o foram detectadas correla es estatisticamente significativas entre a fun o pulmonar e o germe colonizador da via aérea ou o genótipo. Conclus o: O padr o evolutivo das altera es funcionais pulmonares encontrado nos pacientes está de acordo com o descrito na literatura, onde predomina o distúrbio ventilatório obstrutivo com redu o precoce dos fluxos terminais e acometimento tardio da CVF.
