Sourdough bacterial dynamics revealed by metagenomic analysis in Brazil.

This study dealt with the influence of the temperature on the bacterial dynamics of two spontaneously fermented wheat sourdoughs, propagated at 21 ±â€¯1 °C (SD1) and 30 ±â€¯1 °C (SD2), during nine backslopping steps (BS1 to BS9). Proteobacteria was the only phylum found in flour. Escherichia hermannii was predominant, followed by Kosakonia cowanii, besides species belonging to the genera Pantoea and Pseudomonas. After one step of propagation, Clostridium and Bacillus cereus group became predominant. Lactobacillus curvatus was found at low relative abundance. For the second backslopping step, Clostridium was flanked by L. curvatus and Lactobacillus farciminis. From BS4 (6th day) onward, lactic acid bacteria (LAB) became predominant. L. farciminis overcame L. curvatus and remained dominant until the end of propagations for both sourdoughs. At 21 °C, Bacillus, Clostridium, Pseudomonas, and Enterobacteriaceae were gradually inhibited. At the end of propagation, SD1 harbored only LAB. Otherwise, the temperature of 30 °C favored the persistence of atypical bacteria in SD2, as Pseudomonas and Enterobacteriaceae. Therefore, the temperature of 21 °C was more suitable for sourdough propagation in Brazil. This study enhanced the knowledge of temperature's influence on microbial assembly and contributed to the elucidation of sourdough microbial communities in Brazil.

Indicadores de sa?de bucal da aten??o b?sica: a compreens?o e a informa??o registrada pelos cirurgi?es-dentistas / Oral health indicators in primary health care: the understanding andthe information recorded by dentist-surgeons

Objective: This study aimed to know the understanding of Oral health indicators recommended by the Ministry of Health by dentists in the family health strategy of the state of Cear? in 2008. Methods: It is a descriptive, cross-sectional study in which it was used a questionnaire to obtain the data concerning the way information on oral health actions performed in Family Health Care Units and other social spaces are registered, as well as investigate their knowledge about oral health indicators. The calculation of the sample of dentist-surgeons adopted an absolute sampling error of 6.8% and a significance level of 5%, resulting in an initial sample of 175 dentists; however, only 159 participated in this study according to the inclusion criteria. For instance, they should have been working in the service in the period from 2001 to 2007. In all, 32 cities participated in the research, distributed in 18 Regional Health Cells selected by drawing lots. The data were processed in the program SPSS version 17.0 and considered statistically significant the inferential analyses with p < 0.05.Results: it was observed that there are differences between the interpretation of the indicators objectives and the data relating to oral health actions recorded by dentist-surgeons from the Family Health Strategy. They also differ from the guidelines of the Ministry of Health.Conclusion: The pregnant present some knowledge about oral health that can be improved by means of educational, preventive and healing programs. This group exert big it influences in the family ambit, could act as agents multipliers and avoiding the child's precocious contamination.

Objetivo: Conhecer o entendimento e informa??es fornecidas pelos cirurgi?es-dentistas atuantes na Estrat?gia Sa?de da Fam?lia do Estado do Cear? no ano de 2008 acerca dos indicadores de Sa?de Bucal preconizados pelo Minist?rio da Sa?de. M?todos: Para isso, utilizou-se um instrumento (question?rio) que foi aplicado aos cirurgi?es-dentistas atuantes na Estrat?gia Sa?de da Fam?lia do Estado, onde se indagou a respeito do conhecimento deles sobre os indicadores de Sa?de Bucal e como costumavam informar as a??es de Sa?de Bucal que realizavam diariamente nas Unidades B?sicas de Sa?de da Fam?lia e nos demais espa?os sociais em que atuavam. Resultados: Observou-se que h? diverg?ncias entre a interpreta??o dos objetivos dos indicadores e o registro dos dados relativos ?s a??es de Sa?de Bucal pelos cirurgi?es-dentistas atuantes na Estrat?gia Sa?de da Fam?lia. Conclus?o: H? a necessidade de serem implementadas medidas de capacita??o permanente para esclarecer aspectos relacionados aos indicadores deSa?de Bucal.

Osteoporose idiopatica juvenil. Apresentacao de dois casos. / Juvenile idiopathic osteoporosis. Report of 2 cases

A osteoporose idiopatica juvenil e uma forma rara de osteoporose que tem inicio, geralmente, entre os 8 e 14 anos de idade, evoluindo ate a puberdade, epoca em que tende para a cura espontanea, deixando como sequelas as complicacoes que tenham ocorrido durante seu desenvolvimento. Nao ha tratamento especifico. E uma entidade que deve merecer a atencao de reumatologistas e pediatras, apesar de sua insignificante frequencia, pois, alem de entrar no diagnostico diferencial de inumeras doencas (sindrome de Cushing, leucoses agudas, anemia falciforme, talassemia, osteogenese imperfeita, raquitismo, etc.), pode ser erroneamente interpretada como doenca do grupo propriamente reumatico, como aconteceu com os nossos dois pacientes aqui descritos, um tendo sido diagnosticado como febre reumatica e outro como artrite reumatoide juvenil
