Qualidade de vida em mulheres no climatério atendidas na Atenção Primária

The experience of menopause is increasingly present, and demand strategies to improve the quality of life of women during this period. This research aimed to evaluate the quality of life for women in the climacteric phase, with or without the use of hormone replacement therapy (HRT). This is a longitudinal epidemiological study of a sample of 99 women per group. It was evaluated the sociodemographic, clinical and behavioral characteristics. It was used the Menopause Rating Scale (MRS) and the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36). For data analysis, it was used the Student t test, chi-square and Tukey. HRT users had an average age of 50.76 ± 3.63 years, and nonusers of 48.95 ± 6,27anos (p = 0.01). It was identified a higher frequency of moderate climacteric symptoms of mild intensity. The social aspects evidenced scores below 50 for the two groups. There were differences between groups with respect to the components of the SF-36 and MRS to general health, functional capacity, lower capacity, depression, insomnia and vasomotor phenomena.

Caracterização estrutural da Zona de Falha de Cássia-MG

A Zona de Falha de Cássia constitui um feixe de falhas de direção preferencial NW-SE e aproximadamente 2 km de largura. Dados de campo, petrográficos e microestruturais evidenciam uma longa história deformacional da zona de falha. Assim, foram caracterizadas três fases de atividade/movimentação da Zona de Falha de Cássia. A primeira fase (précambriana) é caracterizada por deformação em regime dúctil, acarretando na geração de milonitos formados em condições metamórficas de fácies xisto verde. Este é o estágio de formação da falha, apresentando caráter transcorrente oblíqua, com movimentação sinistral inversa. A segunda fase corresponde a uma reativação da zona de falha como uma falha normal, com bloco alto a NE e bloco baixo a SW da referida estrutura. Seu registro é dado pela ocorrência localizada de brechas e cataclasitos. Este episódio de deformação eminentemente rúptil é correlacionado com o Soerguimento do Alto Paranaíba, o que indica movimentação da falha no Neocretáceo. A terceira e última fase é marcada pela formação de depósitos sedimentares plio-pleistocênicos compostos por brecha sedimentar de leques aluviais e sedimentos argilosos lacustres. Tais depósitos são interpretados como originados pelo represamento da drenagem subatual e conseqüente mudança do nível de base local, em decorrência de uma reativação da Zona de Falha de Cássia. O referido pacote sedimentar apresenta-se localmente cortado por fraturas, zonas brechadas e falhas, caracterizando atividade neotectônica na região. Além disso, foi mostrada a forte influência da zona de falha no desenvolvimento da paisagem da região, sendo constatada a inversão do relevo e da drenagem na área estudada.

Estudo da influência das resinas termofixas uréia formaldeído (UF) e melamina formaldeído (MF) nas características físicas e mecânicas de painéis MDF

Thermosetting resins are very important in the production of MDF panels. They act as an adhesive in the process of compacting and consolidating the fiberboard. Thermoset resins commonly used in this process are based resin urea formaldehyde (UF) and melamine formaldehyde (MF). The first has a higher demand due to its low cost and good performance in meeting the specifications and standards. The second has a high cost compared to MF resin, but adds greater value to the MDF panel, because it gives greater moisture resistance. The process of manufacture of MDF boards was briefly presented in this study to facilitate the understanding of the work. Samples of thermosetting resins (UF and MF) were subjected to physical-chemical seeking to relate these results to the technological performance presented by their respective samples of MDF boards. Two other samples of MDF panels were subjected to physical and mechanical tests. Results were analyzed and related to the award of their respective thermoset resin. Instruments like Dahmos Trend Manager ® and Grecon Dax 5000 and TG - DSC analysis were used in this study to assist in the analysis of the results. It was observed that the results of the analysis of thermosetting resins were within the specified. Such resins do not directly influence the technological tests provided by the MDF panels, but it has been found that the process variables such as humidity and fiber production rate interfere with the performance of the resin accelerating the reaction and therefore their influence on the physical-mechanical properties of the panels MDF. Samples of MDF panels with UF and MF met all the specifications required by the Brazilian standard with regard to the technological quality. The increased demand for UF resin market is justified by the service specifications...

Uma proposta para utilização do computador no processo de ensino e aprendizagem dos primeiros números do sistema hindu-arábico

The aim of this work is presenting the development and the results of a research, which focus of interest has been the making of softwares that could help the process of teaching and learning of the hindu-arabic numerals system, on children in the alphabetical stage. Since the most important presupposes to this work are the development of the number concept according to Jean Piaget (1986-1980) and the reality of the classroom, then three different moments have been fixed: the creation of a beginning scheme of computer activities; the aplication of these activities on children in the alphabetical stage; and, finally, an analysis of the limits and possibilities of these activities while an environment cause of actions that would benefit the process of teaching and learning of the mentioned content. Finally, based on the anlysis of the results obtained, the next step was fixing a more consistant set of computer activities, which makes up a proposal to the use of computer in the process of teaching and learning of the first hindu-arabic numbers

Morphology and adhesion on blood components in root surfaces treated by a piezoelectric ultrasonic: an in vitro study

The aim of this study was to evaluate the morphology and adhesion of blood components on root surfaces instrumented with piezoelectric ultrasonic Piezon Master Surgery. Methods 10 teeth were used in this study. The teeth had their proximal divided into four areas that received different treatments: Group 1: untreated control Group 2: scaling with manual instrument; Group 3: scaling with ultrasound; Group 4: Scaling with manual instruments and ultrasound. We obtained 20 samples, 10 of which were used to analyze the morphology and the other 10 were used for analysis of adhesion of blood components. The specimens were analyzed by scanning electron microscopy. Photomicrographs were analyzed by the scores of adhesion of blood components and the index of root morphology. The results were statistically by the Kruskall-Wallis and Mann-Whitney with a significance level of 95%. Results The morphological analysis showed that the Group 1 had a surface unchanged in relation to other groups (Group 1 X Group 2 = 0.0025; Group 1 X Group 3 = 0.0003; Group 1 X Group 4 = 0.0003) and Group 2 presented a smoother surface compared to Group 1 and groups instrumented with ultrasound (Group 2 X Group 3 = 0.0025; Group 2 X Group 4 = 0.0025) there were no statistical differences between the Groups 3 and 4. analysis of adhesion of blood components showed that the Groups 2, 3 and 4 had no statistically significant differences between themselves, but more biocompatible surfaces promoted the surface untreated control (Group 1 X Group 2 = 0.02; Group 1 X Group 3 = 0.04; Group 1 X Group 4 = 0.005). Conclusion The instrumentation with piezoelectric ultrasonic promoted an irregular root surface, but did not negatively affect the adhesion of blood components.

The influence of different implant surfaces on osseointegration in diabetes: a systematic review of the literature

AIM: The aim of this study was to evaluate, through a systematic review of the literature, the effects of different implant surface modifications on osseointegration in diabetic subjects. METHODS: A search was performed of the PubMed database, using a combination of the following keywords: “Implant surface” OR “Dental implants” AND “Diabetes” OR “Hyperglycemia”. Papers published in English between January 1960 and November 2013 were selected. All experimental models were considered in this search, but case reports and in vitro studies were excluded from this review. RESULTS: The initial search identified 182 articles. After reading the titles and abstracts, 39 articles were selected for full reading. Finally, 4 papers were selected after evaluation of all the papers, and these papers are discussed in this review. Due to the methodological heterogeneity of the selected studies, it was not possible to perform a meta-analysis of the data. CONCLUSION: It can be concluded that although the benefits of surface modifications present in individuals with diabetes have biological plausibility, there is little evidence of the benefits of these modifications.

A utilização do enxerto ósseo autógeno para tratamento de lesão de furca grau II

Destruction of bone and periodontal ligament as a result of periodontal disease can lead to anatomical defects in the furcation area. Treatment of these lesions is a major challenge to the clinician. Periodontal instruments have limited access to this area and plaque and calculus removal from root surfaces are extremely difficult. For proper treatment planning a number of factors must be taken into consideration to achieve immediate and long term success. Surgical therapy associated with bone grafts may be a viable option in the treatment of class II furcation defects, aiming to restore lost tissues. The aim of this paper is to report a clinical case where a simplified surgical approach with the use of autogenous graft was used to treat a class II furcation defect Twelve months after the surgery, an increase in clinical attachment level and pocket depth reduction resulted in a complete closure of the furcation lesion.

Tratamento de recessões gengivais múltiplas: uma abordagem mais conservadora

Periodontal therapy has undergone significant changes in recent decades. While in the past the only goal was to restore gingival health, with no concern about the possible consequences of the disease treatment, currently the procedures are performed in a less invasive manner, to maintain aesthetic periodontal results or even recover them. Gingival recession is an alteration frequently found in patients and may be a complaint for causing various complications. For their treatment, several surgical techniques are reported in the literature. The techniques that are more predictable are those that associate a subepithelial connective tissue graft and a coronally repositioned flap. The original technique consists in performing two vertical incisions for an extensive release of the flap and its stabilization in a coronal position. Although this procedure is extremely widespread in the literature, the search for less invasive surgeries without the use of vertical incisions are the current aim of periodontal plastic surgeries, since they present several advantages. The aim of this paper is to demonstrate a case where adjacent, deep and multiple recessions were present resulting in aesthetic problems, which was resolved by a less invasive approach using a surgical technique in envelope and a subepithelial connective tissue graft.
