Subacute L5 Paresis Following a Capoeira Presentation

A young female suffered minor low back trauma during a capoeira presentation. She was initially diagnosed with an acute episode of uncomplicated low back and radicular pain. She kept training and competing until developing paresthesia and weakness of the right leg six weeks later. Physical examination revealed sensory and motor deficits compatible with L5 nerve root compression. The MRI revealed an L5-S1 disc extrusion compressing the right L5 nerve root. Nerve root decompression and partial discectomy were performed, and seven months later she was competing without restrictions. We present our approach and discuss possible pathological mechanisms that may explain this unusual presentation.info:eu-repo/semantics/publishedVersio

Total bilateral ruptures of the knee extensor apparatus

OBJECTIVE: Bilateral extensor tendon ruptures of the knee are rare and have only been published in the form of case reports or small series. METHODS: Seven patients corresponding to 14 extensor tendon ruptures of the knee were evaluated by the same examiner after a minimum one year post-surgery. Clinical and radiographic evaluations were performed; for statistical analysis, the level of significance was set at 0.05. RESULTS: The most common injury was patellar tendon rupture (n = 9; 64.29%) followed by quadriceps tendon rupture (n = 5, 35.71%). The intrasubstance was the most affected location (57.15%), followed by the myotendinous junction (21.43%) and the patellar bone insertions (21.43%). Quadriceps tendon ruptures were more prevalent in patients older than 50 years, while patellar tendon ruptures tended to occur in younger individuals. All but one patient had recognized risk factors for tendinous degeneration and rupture: 75% of the cases suffered from diseases, 50% had history of drug use and/or abuse, and 37.5% had both disease and drug use history. Mean attained values for flexion ROM were 124.64° ± 9.43 (110-140°) and 89.57 ± 6.02 (78-94) for Kujala score. More than half of the patients complained of residual pain and quadriceps muscular weakness. Mean age was younger in the individuals who complained of residual pain. CONCLUSION: Bilateral tendon ruptures of the knee extensor apparatus ruptures are rare and serious injuries, mostly associated with risk factors. Early surgical repair and intensive rehabilitation program for bilateral extensor tendon ruptures of the knee may warrant satisfactory functional outcomes in the medium to long term, despite non-negligible levels of residual pain, quadriceps muscle weakness, and atrophy.info:eu-repo/semantics/publishedVersio

A new approach for predicting PAT-pumps operating point from direct pumping mode characteristics

144-148This study presents diverse correlations used to predict Pumps-as-Turbines (PAT)-pumps operating point, based on results from direct mode of pump operation. In order to ascertain accuracy of correlations, flow in the pump is computed for direct (pump) and reverse (turbine) operating modes. Accuracy of computations is checked by comparing RANS (Reynolds-Averaged Navier-Stokes) results with experiments for direct mode. A new approach is proposed for PAT power plant design based on a  constant head, instead of traditional operation, in constant flow rate. A full PAT characteristic curve map can be obtained using numerical computation

White Book on Physical and Rehabilitation Medicine (PRM) in Europe. Chapter 10. Science and research in PRM: specificities and challenges

In the context of the White Book of Physical and Rehabilitation Medicine (PRM), this paper deals with Research, the future of PRM. PRM students and specialists are mainly involved in biomedical research, investigating the biological processes, the causes of diseases, their medical diagnosis, the evaluation of their consequences on functioning, disability and health and the effects of health interventions at an individual and a societal level. Most of the current PRM research, often interdisciplinary, originates from applied research which, using existing knowledge, is directed towards specific goals. Translational medical research, research and development, implementation research and clinical impact research are in this field. PRM physicians, mainly master or PhD students, are nowadays increasing their participation in basic research and in pre-clinical trials. PRM physicians are involved in primary research, which is an original first hand research, but also in secondary research, which is the analysis and interpretation of primary research publications in a field, with a specific methodology. Secondary research remains an important activity of the UEMS PRM section and it will be the field of the new created Cochrane Rehabilitation. Secondary research with interest for persons with disabilities, will be developed world wide on the basis of evidence based medicine, with the participation of PRM physicians and of all other health and social professionals involved in rehabilitation. The development of research activities with interest for PRM in Europe is a challenge for the future, which has to be faced now. The European PRM schools, the European master and PhD program with their supporting research and clinical facilities, the European PRM organizations with their websites, the PRM scientific journals and European congresses are a strong basis to develop research activities, together with the development of Cochrane Rehabilitation field and of our cooperation with European high level research facilities, European and international scientific societies in different fields. PRM will be a leader in this field of research
