A eficácia entre duas intervenções na Síndrome do Canal Cárpico

A Síndrome do Canal Cárpico (SCC) é a neuropatia compressiva mais comum do membro superior, causada pela compressão direta sobre o nervo mediano no interior do canal cárpico.Os resultados deste estudo mostram em cada um dos grupos, após a intervenção, uma melhoria estatisticamente significativa da sintomatologia no G-AFN (p=0,02) e no GTRN/ EAA (p=0,004) e uma melhoria estatisticamente significativa do estado funcional no G-AFN (p=0,022). Verificamos também em cada um dos grupos, após a intervenção, uma melhoria estatisticamente significativa na “Força de preensão” (p=0,005), na “Pinça polegar/dedo indicador” (p=0,021), na “Pinça polegar/dedo médio” (p=0,026) e “Pinça polegar/dedo anular” (p=0,026) no G-AFN, e uma melhoria estatisticamente significativa na “Pinça polegar/indicador” (p=0,016), na “Pinça polegar/dedo médio” (p=0,035), na “Pinça polegar/dedo anular” (p=0,010), na “Pinça trípode” (p=0,005) e na “Pinça lateral” (p=0,051) no G-TRN/EAA. Após a intervenção, não verificamos diferenças estatisticamente significativas nos valores das escalas de gravidade de sintomas (p=0,853) e de estado funcional (p=0,148) entre os grupos, mas diferenças estatisticamente significativas nos valores dos testes neurofisiológicos (p=0,047) e força de preensão da mão (p=0,005). Do estudo, concluímos que a utilização da intervenção articular/fascial/neural (AFN) e a intervenção com tala de repouso noturna e exercícios de auto alongamento (TRN/EAA), beneficia os indivíduos com SCC não severa, como nos casos incipientes, ligeiros ou moderados. Os indivíduos com esta condição clínica apresentam sintomatologia caraterística de dor, parestesia, especialmente noturna e disfunção muscular da mão. Tais manifestações originam perda funcional com implicações nas áreas de desempenho ocupacional, nomeadamente, nas atividades da vida diária, produtivas e de lazer. O tratamento conservador na SCC não severa, como nos casos incipientes, ligeiros e moderados, apesar de controverso, é recomendado. O tema suscita o nosso interesse, razão pela qual nos propomos realizar um estudo experimental em indivíduos com o diagnóstico clínico de SCC não severa e aplicar num grupo a intervenção articular, fascial e neural (AFN) e noutro grupo a intervenção com tala de repouso noturna e exercícios de auto alongamento (TRN/EAA). O estudo tem como principais objetivos, por um lado, verificar o impacto das intervenções em cada um dos grupos e, por outro lado, comparar o seu impacto entre os grupos, no que respeita à gravidade de sintomas, ao estado funcional, à força de preensão da mão e força de pinças finas. Fomos também comparar os resultados dos testes neurofisiológicos (Velocidade de Condução Motora) antes e depois da intervenção AFN e da intervenção com TRN/EAA, e averiguar o seu impacto nos valores da latência motora distal e da velocidade de condução sensitiva, entre os grupos. Identificamos também quais as variáveis sócio demográficas e as que caraterizam a patologia que estão relacionadas com o problema em estudo e com os valores obtidos com as escalas do Boston Carpal Tunnel Questionnaire (BCTQ), no grupo articular, fascial e neural (G-AFN) e no grupo com tala de repouso noturna e exercícios de auto alongamento (G-TRN/EAA). Para a concretização do estudo, recorremos a uma amostra de 23 indivíduos de ambos os sexos do Hospital Curry Cabral, Empresa Pública Empresarial -Centro Hospitalar de Lisboa Central (HCC, EPE -CHLC).

Acupuntura na abordagem da Síndrome da Cauda Equina em pequenos animais Trabalho

Nowadays, in any area that acts within the veterinary medicine, we talk a lot of specialists. Specialists in neurology, cardiology, dermatology, endocrinology, finally, more specialized in a subject, better is the veterinarian. However, on one hand to deepen the knowledge helped in the discovery of new diagnostics and treatments, secondly, a bit lost sight of the patient as a whole. Traditional Chinese medicine, one of whose branches is acupuncture, is aimed at exactly this approach to be fully alive, where all body is interconnected and the disease is not seen as the imbalance of one system, but, as the imbalance between our being and the environment external. Acupuncture is an alternative in the treatment of many diseases, among them Cauda Equina Syndrome, and consists of stimulating specific points on the body surface, which help the body return to its natural harmony. A Cauda Equina Syndrome is a frame subsequent to a neuromuscular spinal cord at the level of the spinal canal of the lower lumbar spine and sacral, whose treatment is almost always surgical. This study aims to show the relevance of acupuncture treatment in this condition and report the importance of the philosophy of traditional Chinese medicine nowadays, even when their arms are not in the treatment of choice

Is there a difference between narrowing of the spinal canal and neurological deficits comparing Denis and Magerl classifications?

We have read with great interest the retrospective study by Caffaro and Avanzi1 evaluating the relation between narrowing of the spinal canal and neurological deficits in patients with burst-type fractures of the spine. The authors are to be commended for obtaining detailed neurological and radiological data in a large cohort of 227 patients. The authors conclude: “The percentage of narrowing of the spinal canal proved to be a pre-disposing factor for the severity of the neurological status in thoracolumbar and lumbar burst-type fractures according to the classifications of Denis and Magerl.” Although this conclusion is mainly in accordance with previous findings, we would like to comment on the methodological approach applied in the current study.

Porous Ca-Si-based nanospheres : a potential intra-canal disinfectant-carrier for infected canal treatment

The aim of this study is to develop a new intra-canal disinfectant-carrier for infected canal treatment. To achieve this purpose, a new porous Ca-Si (CS)-based nanosphere was synthesized and characterized. Results showed that the nanospheres can infiltrate into dentinal tubules and released the ampicillin over one week time in a sustained manner. The release of ampicillin from spheres has significantly antibacterial property. Extensive and well-organized in vitro mineralization and crystallization of apatite were induced on the surface of dentin slices covered by CS nanospheres. All these features indicate that the porous CS nanospheres may be developed into a new intra-canal disinfectant-carrier for infected canal treatment.

Revascularization and tissue regeneration of an empty root canal space is enhanced by a direct blood supply and stem cells

Background Regenerative endodontics is an innovative treatment concept aiming to regenerate pulp, dentin and root structures. In the diseased or necrotic tooth, the limitation in vascular supply renders successful tissue regeneration/generation in a whole tooth challenging. The aim of this study is to evaluate the ability of vascularized tissue to develop within a pulpless tooth using tissue engineering techniques. Materials and methods A pulpless tooth chamber, filled with collagen I gel containing isolated rat dental pulp cells (DPC) and angiogenic growth factors, was placed into a hole created in the femoral cortex or into its own tooth socket, respectively. The gross, histological and biochemical characteristics of the de novo tissue were evaluated at 4 and 8weeks post-transplantation. Results Tooth revascularization and tissue generation was observed only in the femur group, confirming the important role of vascular supply in tissue regeneration. The addition of cells and growth factors significantly promoted connective tissue production in the tooth chamber. Conclusion Successful revascularization and tissue regeneration in this model demonstrate the importance of a direct vascular supply and the advantages of a stem cell approach. © 2012 John Wiley & Sons A/S.

A fuzzy logic based dynamic wave model inversion algorithm for canal regulation

A fuzzy logic based centralized control algorithm for irrigation canals is presented. Purpose of the algorithm is to control downstream discharge and water level of pools in the canal, by adjusting discharge release from the upstream end and gates settings. The algorithm is based on the dynamic wave model (Saint-Venant equations) inversion in space, wherein the momentum equation is replaced by a fuzzy rule based model, while retaining the continuity equation in its complete form. The fuzzy rule based model is developed on fuzzification of a new mathematical model for wave velocity, the derivational details of which are given. The advantages of the fuzzy control algorithm, over other conventional control algorithms, are described. It is transparent and intuitive, and no linearizations of the governing equations are involved. Timing of the algorithm and method of computation are explained. It is shown that the tuning is easy and the computations are straightforward. The algorithm provides stable, realistic and robust outputs. The disadvantage of the algorithm is reduced precision in its outputs due to the approximation inherent in the fuzzy logic. Feed back control logic is adopted to eliminate error caused by the system disturbances as well as error caused by the reduced precision in the outputs. The algorithm is tested by applying it to water level control problem in a fictitious canal with a single pool and also in a real canal with a series of pools. It is found that results obtained from the algorithm are comparable to those obtained from conventional control algorithms.

Analysis of transients in a canal network

A generalised formulation of the mathematical model developed for the analysis of transients in a canal network, under subcritical flow, with any realistic combination of control structures and their multiple operations, has been presented. The model accounts for a large variety of control structures such as weirs, gates, notches etc. discharging under different conditions, namely submerged and unsubmerged. A numerical scheme to compute and approximate steady state flow condition as the initial condition has also been presented. The model can handle complex situations that may arise from multiple gate operations. This has been demonstrated with a problem wherein the boundary conditions change from a gate discharge equation to an energy equation and back to a gate discharge equation. In such a situation the wave strikes a fixed gate and leads to large and rapid fluctuations in both discharge and depth.
