ABSTRACT
BACKGROUND: People with stroke excessively move their trunk, when reaching and grasping objects. OBJECTIVE: To determine if the addition of trunk restraint to modified constraint-induced movement therapy (mCIMT) was better than mCIMT alone in improving strength, function, and quality of life after stroke. METHODS: A pilot randomized double-blinded clinical trial was conducted. Twenty-two participants with chronic stroke were randomly assigned to an experimental group that received mCIMT plus trunk restraint, or a control group (only mCIMT). Primary outcomes were the amount of use and quality of movement of the paretic upper limb (UL), determined by the Motor Activity Log (MAL) scores. Secondary outcomes included the observed performance of the paretic UL during unimanual and bimanual tasks, kinematics of reaching, strength, and quality of life. RESULTS: Both groups demonstrated significant improvements in the MAL scores and in the time to perform bimanual activities immediately after the interventions. However, no between-group differences were observed. CONCLUSIONS: The addition of trunk restraint to mCIMT resulted in no additional benefits, compared with mCIMT alone with stroke individuals with mild to moderate impairments. Unimanual and bimanual improvements were observed after mCIMT, regardless of trunk restraint, and the intervention did not adversely affect their reaching patterns.

BACKGROUND: Hand function impairment is the main disability among children with hemiplegic cerebral palsy. They start to perform most motor tasks exclusively with their unaffected upper limb, thereby causing a phenomenon described as learned nonuse. To minimize this phenomenon, constraint-induced movement therapy (CIMT) is emerging as a rehabilitation strategy for improving the functional use of the affected upper limb. OBJECTIVE: The aim of this study was to conduct a systematic review of the literature on the effects of CIMT among children with hemiparetic cerebral palsy. METHOD: This was a systematic review of the literature using randomized clinical trials to analyze the effects of CIMT on the functional performance of the affected upper limb among children with hemiparesis. RESULTS:Five studies fulfilled the inclusion criteria, and the methodological quality ranged from 2 to 6 (4.4±1.36), according to the PEDro scale. The studies included involved a total of 99 individuals who showed that CIMT had positive effects, compared with other rehabilitation strategies or no therapy. However, there was considerable variation between the studies regarding the measurement instruments used and the outcomes evaluated. CONCLUSION: Although the studies achieved positive results, it is difficult to draw any clear-cut conclusion regarding the effectiveness of CIMT because of the small number of studies and their methodological differences.
CONTEXTUALIZAÇÃO: A deficiência de função manual é a principal incapacidade em crianças com paralisia cerebral do tipo hemiplégica, as quais passam a realizar a maioria das tarefas motoras exclusivamente com o membro superior não acometido, determinando um fenômeno descrito como desuso aprendido. Para minimizar esse fenômeno, a terapia de movimento induzido por restrição (TMIR) emerge como estratégia de reabilitação para melhorar o uso funcional do membro superior acometido. OBJETIVO:O propósito desse estudo foi conduzir uma revisão sistemática da literatura para os efeitos da TMIR em crianças com hemiparesia devido à paralisia cerebral. MÉTODO: Revisão sistemática da literatura com ensaios clínicos aleatorizados analisando os efeitos da TMIR no desempenho funcional do membro superior acometido em crianças com hemiparesia. RESULTADOS:Cinco estudos preencheram os critérios de inclusão e a qualidade metodológica variou entre 2 e 6 (4.4±1.36) de acordo com a escala PEDro. Os estudos incluídos envolveram um total de 99 indivíduos e demonstraram efeitos positivos da TMIR em comparação a outras estratégias de reabilitação ou ausência de terapia. Entretanto, foram encontradas variações consideráveis nos estudos em relação aos instrumentos de medidas utilizados e os desfechos dos estudos. CONCLUSÃO: Embora os estudos tenham alcançado resultados positivos, a definição de uma conclusão sobre a efetividade da TMIR é dificultada em função do pequeno número de estudos e suas diferenças metodológicas.
ABSTRACT
OBJECTIVE: The effects on periodontal tissues of adjacent second molars after semi-impacted mandibular third molar surgery were evaluated. The influence of flap design was studied. METHODS: Twenty volunteers randomly underwent the three-cornered flap technique (group A) or the distal wedge flap technique (group B). The periodontal probing depth was measured by using a 'Williams'-type probe just prior to surgery and three months post-operatively. Six sites, mesio-buccal, buccal, disto-buccal, disto-lingual, lingual and mesio-lingual, around the second molar were selected for measurement. Kruskal-Wallis test and Dunn test (post hoc) were used. Significance level was set at 5%. RESULTS: There were no complications (oedema, alveolitis, etc.) in any of the patients of the study. The results showed that both methods caused shallow pocket depth (P > 0.05) and there were no statistically significant differences between the flap techniques (P > 0.05). Flap design was not an important factor affecting the periodontal status of the second molar. CONCLUSION: The decision to use any of the various flap designs for access to mandibular third molars should be based on operator preference rather than on the assumption that periodontal health of the adjacent second molar will be improved.

Introdução: A queda extrínseca dos mecanismos de defesa de um hospedeiro é vista classicamente como uma infecção, que resulta na aquisição de um tecido normal, de um novo microorganismo, cuja virulência é fundamental para a sua patogenia.Na década de 50, estudos comprovaram que bactérias e endotoxinas podem ultrapassar a barreira intestinal e atingir a circulação, demonstrando ainda, que a flora intestinal representa uma importante fonte para o desenvolvimento da infecção sistêmica. Objetivo: o presente estudo visa avaliar a ocorrência de transmigração bacteriana em apendicite experimental induzida em coelhos, mediante a oclusão completa do apêndice vermiforme. Métodos: foram utilizados 24 coelhos brancos, da linhagem Nova Zelândia, com peso corporal variando de 2500 a 3000 gramas, sendo então divididos em 2 grupos. Os animais do Grupo I foram submetidos a laparotomia mediana e retirada de fragmentos do baço, rim esquerdo, pulmão direito, linfonodo abdominal, conteúdo da luz do apêndice vermiforme e sangue da veia porta para cultura. Os animais do Grupo II foram submetidos a laparotomia mediana e oclusão completa do apêndice vermiforme para a indução de apendicite e, após 24 horas, realizada a coleta do material nos moldes do Grupo I. Resultados: No Grupo controle (Grupo I), não se observou o crescimento de bactérias nas amostras analisadas. No Grupo experimento (Grupo II), observou-se o crescimento de Escherichia coli em todos os animais. Conclusão: Ocorreu transmigração bacteriana após 24 horas de observação em coelhos com apendicite experimental.
