Efeito do kinesio taping® no desempenho neuromuscular do quadríceps e no equilíbrio em sujeitos submetidos à reconstrução do ligamento cruzado anterior: ensaio clínico e randomizado

Objetivo: Investigar os efeitos imediatos do Kinesio Taping® no desempenho neuromuscular do Quadríceps Femoral (QF) de indivíduos submetidos à reconstrução do Ligamento Cruzado Anterior (LCA). Metodologia: trata-se de um ensaio clínico e randomizado composto por 45 indivíduos do sexo masculino que se encontravam entre 12ª e 17ª semanas após reconstrução do LCA. Todos foram submetidos a uma avaliação inicial composta pela análise do equilíbrio postural, através da baropodometria; determinação do Senso de Posição Articular (SPA), seguidas das avaliações isocinéticas excêntricas e concêntricas a 600/s, concomitante com a captação do sinal eletromiográfico do músculo Vasto Lateral (VL). Posteriormente foram alocados de forma aleatória em Grupo Controle (GC), Grupo Placebo (GP) e Grupo Experimental (GE). Os indivíduos do GE foram submetidos ao protocolo sugerido (aplicação do Kinesio Taping® no QF do membro acometido), enquanto os do GP utilizaram a aplicação do Kinesio Taping® sem as recomendações propostas pelo método. Já os indivíduos do GC permaneceram em repouso por dez minutos, sendo todos os indivíduos submetidos a uma reavaliação de forma idêntica à primeira. Foram analisadas as seguintes variáveis: pico de torque médio, pico de torque/peso corporal, potência muscular e erro absoluto do SPA para a dinamometria; amplitude ântero-posterior e médio-lateral para a baropodometria; e a amplitude de ativação muscular (Root Means Square - RMS) por meio da eletromiografia de superfície. Resultados: Nenhuma das variáveis analisadas apresentou diferenças intergrupo ou intragrupo. Conclusão: O Kinesio Taping® não altera o desempenho neuromuscular do quadríceps femoral de indivíduos submetidos à reconstrução do LCA para nenhuma das variáveis analisadas.

Dual path: a concept to improve the esthetic replacemente of missing anterior teeth with removable partial denture

The dual path of insertion concept for removable partial denture (RPD) design may be used in esthetically demanding situations. When compared to conventional RPDs, the main advantage of this design is the minimal use of clasps. This clinical report describes the treatment of a patient with an anterior maxillary edentulous area using a dual path RPD. The diagnostic cast was surveyed to ensure the adequacy of the undercuts on the mesial surfaces of the anterior abutments, where rigid minor connectors were placed. Inverted V-shaped canine cingulum rest seats were prepared to provide resistance to tooth movement during function. The dual path RPD concept allows excellent esthetic results, minimizes tooth preparation, and reduces the tendency toward plaque accumulation in a Kennedy class IV partially edentulous arch.

The role of supraspinal excitability in the development of healthy-limb deficits following anterior cruciate ligament injury

In the current study, we examined how supraspinal and spinal excitability were altered bilaterally after unilateral anterior cruciate ligament reconstruction (ACLr). 7 participants with ACLr and 7 healthy controls underwent transcranial magnetic stimulation (TMS) and electrical stimulation. To evaluate supraspinal excitability, resting motor thresholds (RMT) and motor evoked potential (MEP) stimulus response curves (SRC) were used. To measure spinal excitability, H-reflex SRC gain was assessed. Mixed factorial ANOVAs were used to compare measures between limbs and between groups. Cohen’s d was used to assess effect sizes between groups. Data indicated no significant differences between subject groups or between limbs. However, large effect sizes were found between limbs for H-reflex gain and RMTs suggesting that ACLr can have an effect on some of the variables examined. This study identified decreases in strength in the injured limbs and that subjects with an ACL injury exhibited decreases in spinal and supraspinal excitability of the quadriceps compared to Healthy controls.

Cambios en el polo anterior tras la ortoqueratología nocturna

La Ortoqueratología nocturna (OKN) es una técnica que utiliza lentes de contacto especialmente diseñadas y adaptadas al ojo con el fin de modificar el contorno corneal induciendo un aplanamiento en la región central de la córnea, cambiando así el estado refractivo del mismo. El efecto buscado es similar al de la cirugía refractiva salvo que con este sistema, el efecto inducido es reversible. La aparición de lentes capaces de inducir de forma efectiva los cambios deseados en la córnea, en tan sólo siete días de manera rápida, eficaz y reversible, ha propiciado que esta técnica haya comenzado a utilizarse con resultados muy satisfactorios permitiendo que el paciente pueda estar libre de gafas o lentes de contacto durante el día. Esta terapia ha despertado un gran interés en la comunidad científica, convirtiéndose en una alternativa real a la Cirugía Refractiva. Además, se ha reportado en diversos estudios que el uso de lentes de OKN en niños, reduce el crecimiento axial entre un 30% y un 50%, en comparación con los niños que usan gafas o lentes de contacto 1-6 . El auge de la OKN y la creciente utilización de esta técnica en niños para el control de la miopía implica la necesidad de una mayor comprensión del mecanismo por el cual las LC de geometría inversa inducen la corrección del error refractivo en el ojo...

Prevalence of biomicroscopic findings in the anterior segment and ocular adnexa among schoolchildren in Natal/Brazil

Objective: To determine the prevalence of ocular findings of the external structures and anterior segment of the eye, detected by biomicroscopic examination in schoolchildren in Natal (RN) - Brazil. Methods: After previous random selection, 1,024 pupils from elementary and secondary public and private schools in the city of Natal were evaluated from March to June 2001. All were submitted to preestablished standard research norms, consisting of identification, demographic information, ophthalmologic biomicroscopic examination, with slit lamp, performed by ophthalmologists from the “Onofre Lopes” University Hospital. Results: Alterations of the conjunctival and palpebral conditions were the most prevalent (10.4% and 6.2% respectively). Follicles (4.2%) and papillae (3.0%) were the frequent conjunctival lesions, while blepharitis (3.5%) and meibomitis (1.1%) were the most detected abnormalities in the eyelids. Upon examining the cornea, iris, lens and anterior vitreous, the most encountered findings were nubecula (0.5%), papillary membrane reliquiae (0.5%), posterior capsula opacity (0.8%) and hyaloid arteria reliquiae (2.0%). Conclusion: The most prevalent findings affecting the external structures of the eye such as eyelids and conjunctiva, consisted of blepharitis followed by follicular reaction of the conjunctiva. The most prevalent abnormalities in the cornea, iris, lens and anterior vitreous were nubecula, papillary membrane reliquiae, posterior capsular opacity and hyaloid arteria reliquiae, in that order

Identification and functional analysis of novel genes expressed in the Anterior Visceral Endoderm

During early vertebrate development, the correct establishment of the body axes is critical. The anterior pole of the mouse embryo is established when Distal Visceral Endoderm (DVE) cells migrate to form the Anterior Visceral Endoderm (AVE). Symmetrical expression of Lefty1, Cer1 and Dkk1 determines the direction of DVE migration and the future anterior side. In addition to the establishment of the Anterior-Posterior axis, the AVE has also been implicated in anterior neural specification. To better understand the role of the AVE in these processes, we have performed a differential screening using Affymetrix GeneChip technology with AVE cells isolated from cer1P-EGFP transgenic mouse embryos. We found 175 genes which were upregulated in the AVE and 36 genes in the Proximal-posterior sample. Using DAVID software, we characterized the AVE cell population regarding cellular component, molecular function and biological processes. Among the genes that were found to be upregulated in the AVE, several novel genes were identified. Four of these transcripts displaying high-fold change in the AVE were further characterized by in situ hybridization in early stages of development in order to validate the screening. From those four selected genes, one, denominated Adtk1, was chosen to be functionally characterized by targeted inactivation in ES cells. Adtk1 encodes for a serine/threonine kinase. Adtk1 null mutants are smaller and present short limbs due to decreased mineralization, suggesting a potential role in chondrogenesis during limb development. Taken together, these data point to the importance of reporting novel genes present in the AVE.

Abordajes endoscópicos a la base de cráneo anterior

Los abordajes endoscópicos a la base de cráneo anterior se han desarrollado de forma muy importante en las últimas décadas y continúan extendiéndose paralelamente a la aparición de nuevo instrumental y equipo que facilitan su aplicación. Factores importantes que han contribuido a ello son la posibilidad de acceder de forma directa a zonas difíciles y la disminución de morbilidad que pueden aportar, manteniendo los resultados esperados. Pero también tienen desventajas y limitaciones pues requieren conocimiento anatómico y el uso de material específico en un campo quirúrgico limitado por el espacio, estructuras anatómicas vitales y la visión bidimensional. La correcta planificación quirúrgica y la selección de los pacientes son elementos fundamentales. Esto nos permitirá determinar si es posible este tipo de abordaje, conocer la localización de la lesión, la zona de entrada al cráneo y el corredor que deberemos utilizar para ello. Los abordajes endoscópicos, correctamente indicados y planificados son procedimientos seguros y efectivos.
