Impacto da reabilitaçāo implantossuportada na qualidade de vida de pacientes edêntulos: revisāo narrativa

A perda de dentes gera diversas consequências negativas para a saúde. Isto leva a diminuição da qualidade de vida (QoL) em diversos níveis. O edentulismo total é o marco final desta condição afetando drasticamente o bem-estar psicossocial. A terapia com implantes vem sendo usada em larga escala nos últimos anos em substituição das próteses totais. É visto como um método que resolve o problema da falta de estabilidade e retenção associada a estes tratamentos mais convencionais. Esta revisão narrativa da literatura teve como objetivo analisar o impacto da reabilitação implantossuportada na QoL do paciente edêntulo sob sua própria percepção. Os estudos analisados demonstraram, na sua maioria, um aumento desta, medida por questionários do tipo Patient Reported Outcome Measures e, por vezes, confirmada por testes objetivos. Todavia, a natureza subjectiva da QoL e a falta de guidelines padronizadas na sua avaliação tornam difíceis a interpretação e a comparação dos resultados.Tooth loss impairs many negative consequences to oral and general health. It brings less quality of life (QoL) in several levels. Total edentulism is the final mark of this condition that affects seriously the psychosocial well-being. Therapy with dental implants is being used in a large scale replacing the complete dentures. It is seeing as a method that solve problems like instability and lack of retention associated with conventional removable prostheses. The aim of this review was to verify the impact of implant supported rehabilitation in the QoL of the edentulous patients in their own perception. The studies evaluated demonstrated a QoL increase, measured by Patient Reported Outcome Measures questionnaires and confirmed sometimes by objective analysis. However, the subjective nature of QoL and lack of specific standard guidelines makes it difficult to analyze and to compare the outcomes

ARTHROSCOPIC TREATMENT OF FEMOROACETABULAR IMPINGEMENT

ABSTRACTObjective: The purpose of this study is to evaluate the short-term follow-up results of arthroscopic treatment of femoroacetabular impingement. Our hypothesis is that arthroscopic treatment results are favorable. Methods: Between August 2003 and August 2007, 28 hips had femoroacetabular impingement treated by hip arthroscopy. The mean age was 34 years, with mean follow-up period of 27 months. Clinical results were graded with the modified Harris hip score, which was measured pre- and postoperatively. Patients had also their internal rotation analyzed. These parameters were calculated by using Wilcoxon's t test for analysis of nonparametric paired samples performed. Results: The mean preoperative Harris Hip Score was 54.2, improving to 94.8 postoperatively (p<0,001). The mean increase was 37.5 points. We had 4 good results (15%) and 24 excellent results (85%). Preoperatively, the patients had a mean internal rotation of 17°, and, postoperatively, 36°. The average internal rotation increase was 19° (p<0,001). Conclusions: The arthroscopic treatment of femoroacetabular impingement presents satisfactory results

Isoenzyme variation in Melipona rufiventris (Hymenoptera: Apidae, Meliponina) in Minas Gerais State, Brazil

The stingless bee Melipona rufiventris is an important pollinator in several Brazilian ecosystems. Originally widely distributed in Minas Gerais (MG) state, this species is becoming very rare. Therefore this species was included in the endangered species list of MG. We used isoenzyme data for a better understanding of the genetic structure of several M. rufiventris colonies. Samples of 35 colonies were collected from 12 localities and evaluated by nine enzymatic systems, which yielded 17 loci. M. rufiventris genetic variation was found to be low, typical of an endangered species. The proportion of polymorphic loci was 5.88% in both ecosystems. Only Est-4 was polymorphic in colonies from the Forest and Mdh-1 in colonies from the Cerrado. The expected heterozygosity ranged from 0.0068 in the Cerrado to 0.0078 in the Forest. Despite this, enzyme electrophoretic analyses provided a good idea of the diversity between samples from Cerrado and Forest which reinforce the existence of two different “forms” of M. rufiventris in MG, one present in the Cerrado and the other in Forest. This information is of great importance for the conservation of, M. rufiventris in MG
