A humanização no parto e no nascimento: os saberes e as práticas no contexto de uma maternidade pública brasileira

The practice of medicine related to the gestational processes tend to be organized according to the context and the place of work, being thus dependent of the conditions both social and economical, and of the physical structure and the functionality of the services. The high mortality rate in this process has diminished, since 1986, the study made by the World Health Organization (WHO) as to the technical aspects and the social inequalities that influence this situation in different geographical contexts. This culminated recommendations that proposed the reorientation of the dynamical practice of medicine, with a focus on the safety of maternities. Brazil adopted, in the year 2000, the suggestions of the OMS, emphasizing the humanization as the main reason for these actions. However, this discussion tends to not consider the problems caused by the social inequalities and the epidemiological and social conditionings that define the actions of the Unified Health System (Sistema Único de Saúde SUS). In this area, this research seeks to analyze the practices, cares taken, and the universal symbol that promotes and rewards the assistance to the birth of children by the SUS. Besides the analysis of the public documents that deal with this subject, an ethnographic study was developed in a maternity in Natal/RN, considered a model of humanization after receiving the Galba de Araújo prize in 2002. In this stage, the methodological strategies were observed, and the focus of the individual interviews with workers and users of this service. In the analysis of the data, it became evident that the different professional workers and women who gave birth, tend to show concern of the standards the delimit production and reproduction of the practice of medicine, as they favor the absence of a critical posture of the actions destined to the population. Besides this, if became evident that the institutional difficulties associated to the economical, cultural, and political problems also difficult the involvement and the reflection of the workers in favor of assisting changes of the process. There is also a utilization of a perspective prescriptive of humanization in the everyday life of the social workers, without reflection of its meaning. Some workers present, in their statements, a preoccupation with the social and economical aspects that affect the practice of medicine, and with the limitations of the humanization discourse that disarticulates the necessities of those involved in the process of formation, and soon tend to return to the discussion of humanization while a kind practice characterized by the minimization of the interventionist actions. Now the users of the system show themselves before the dynamic of the services, submitting themselves to what is offered while assistance, without questioning and/or reflecting about their usual shortages. Therefore, to think of changes in the know and do of the practice of medicine destined to the birth of children implies reflection on the quotidian production of these practices and of the social contexts that influence the process of assistance in the practice of medicine. Herein it would be possible to predict the appropriation, by different workers concerning their exasperations and necessities, making them active in the pursuit of their rights as citizens

Atividade antifúngica de extratos de plantas a Colletotrichum gloeosporioides

The present work aimed to evaluate the effect fungitoxic of plant extracts on the mycelial growth and on the spores germination of C. gloeosporioides. The plant extracts were obtained starting from dried ground plants, using water and ethilic alcohol as extractor. Twenty-two plant species were used to obtain the extracts. The extracts were tested by means of the incorporation of 20% (v/v) in PDA medium, before or after sterilization. The percentage of inhibition of the mycelial growth (PIM) was determined. Extract in the proportion of 50% was added to a spore suspension used to determine the percentage of inhibition of the spores germination (PIS). The hidroetanolic extracts provided larger PIM of C. gloeosporioides, while larger PIS was obtained with the aqueous extracts. Non autoclaved extracts was the most efficient in mycelial growth of C. gloeosporioides, even more than the autoclaved ones. Aqueous and hidroetanolic extracts of Momordica charantia and hidroetanolic extract of Eucalyptus citriodora provided higher PIM. Aqueous extracts of Luffa acutangula, Eucalyptus citriodora, Chenopodium ambrosioides, and Bauhinia, and hidroetanolic extracts of Ruta graveolens, Eucalyptus citriodora, Zingiber officinale and Chenopodium ambrosioides inhibited more than 90% of spores germination.

Usefulness of catheter tip culture in the diagnosis of neonatal infections

Objective: To determine the number of colony-forming units (CFU) that best correlates with catheter-related infections (CRI) in newborns.Methods: This was a prospective study of semiquantitative cultures of catheter tips obtained from newborns in the neonatal unit at Faculdade de Medicina de Botucatu, state of São Paulo, Brazil. The microorganisms isolated from catheter and peripheral blood cultures were identified and submitted to a drug susceptibility test. The optimal cutoff point was determined by the receiver operating characteristic (ROC) curve.Results: A total of 85 catheters obtained from 63 newborns were studied. Staphylococcus epidermidis was the predominant species in the catheters (75%). Eight of 11 (72.7%) CRI episodes were associated with coagulase-negative staphylococci, six of which were of the S. epidermidis type. ROC curve analysis indicated that the optimal cutoff point for the diagnosis of CRI was 122 CFU.Conclusions: The cutoff point of 122 CFU correlated best with the diagnosis of CRI in newborns.

Exposure to rabies virus in a population of free-ranging capuchin monkeys (Cebus apella nigritus) in a fragmented, environmentally protected area in southeastern Brazil

The aim of this study is to assess the frequency of rabies antibodies in free-ranging capuchin monkeys (Cebus apella nigritus) in a fragmented, environmentally protected, rural area of southeastern Brazil. Thirty-six free-ranging monkeys were tested by the rapid fluorescent focus inhibition test for detection of antibodies against rabies virus. Four individuals (11.11 %) had neutralizing antibody titers a parts per thousand yen0.25 IU/mL, demonstrating rabies virus exposure.

Effect of Nd:YAG Irradiation and Fluoride Application on Dentine Resistance to Erosion in Vitro

Objective: In this paper we evaluated the effect of two fluoridated agents and Nd:YAG irradiation separately and in combination on dentine resistance to erosion. Background Data: The morphological changes in dentin induced by laser treatment may reduce the progression of erosive lesions. Due to the possibility of a synergistic effect of laser with fluoride, this study was conducted. Materials and Methods: Eighty bovine dentine samples (4 x 4 mm) were randomly divided into eight groups, according to the following treatments: G1: untreated (control); G2: acidic phosphate fluoride gel (APF 1.23%) for 4 min; G3: fluoride varnish (NaF 2.26%) for 6 h; G4: 0.5 W Nd: YAG laser (250 mu sec pulse, 10 Hz, 35 J/cm(2), 30 sec); G5: 0.75 W Nd: YAG laser (52.5 J/cm(2)); G6: 1.0 W Nd: YAG laser (70 J/cm(2)); G7: APF + 0.75 W Nd: YAG laser; and G8: NaF + 0.75 W Nd: YAG laser. After the treatments, half of each dentine surface was protected with nail varnish. The samples were stored in artificial saliva (30 mL/sample) for 24 h and submitted to four erosive 1-min cycles. Between the erosive attacks, the blocks were maintained in artificial saliva for 59 min. The erosive wear was evaluated by profilometry. Results: The mean wear (+/- SD, mu m) was: G1: 1.20 +/- 0.20; G2: 0.47 +/- 0.06; G3: 0.81 +/- 0.11; G4: 1.47 +/- 0.32; G5: 1.52 +/- 0.24; G6: 1.49 +/- 0.30; G7: 0.49 +/- 0.11; and G8: 1.06 +/- 0.31 (Tukey's test, p < 0.05). Conclusions: Laser irradiation was not able to reduce dentine erosion. However, fluoride application was able to increase the dentine's resistance to erosion, and APF showed better results than fluoride varnish.
