Lesões desportivas na ginástica artística: estudo a partir de morbidade referida

INTRODUÇÃO: Os níveis de exigência biomecânica devidos ao alto grau de dificuldade na realização de gestos fazem da ginástica artística (GA) uma modalidade com elevado risco de lesões. Assim, é necessário que os aspectos a elas relacionados sejam controlados. OBJETIVO: Analisar a ocorrência de lesões na Ginástica Artística, associando-as a fatores de risco específicos da modalidade e do atleta, a partir de inquérito de morbidade referida. MÉTODOS: Foram entrevistados 54 ginastas, recrutados ao acaso, classificados segundo o nível competitivo em duas categorias: regional e nacional. Utilizou-se o inquérito de morbidade referida (IMR) com a finalidade de reunir dados sobre a natureza da lesão, região corporal e aparelho ginástico. Os dados foram organizados e apresentados sob a forma de distribuição de freqüências e as variáveis, analisadas segundo nível de associação a partir do teste de Goodman para contrastes entre populações multinomiais, considerando significante o valor P < 0,05. RESULTADOS: Presença de lesão durante a temporada foi relatada por 39 (71,70%) atletas, sendo 22 (56,41%) mulheres e 17 (43,59%) homens. Nas categorias regional masculino e feminino e nacional feminino, a maior ocorrência de lesões foi de origem articular, correspondendo a 55,56%, 50% e 45,45% do total, respectivamente. Para o sexo feminino nacional, os membros inferiores foram os mais referidos (68,18%) e, em ambas as categorias, as lesões ocorreram nos aparelhos de saltos (79,41%), enquanto que no sexo masculino nacional o maior número de agravos foi verificado nos aparelhos de apoio e suspensão (72%). CONCLUSÕES: Há elevada freqüência de lesões, acometendo principalmente articulações e membros inferiores, sendo os aparelhos de saltos os mais referidos quanto à ocorrência de acometimentos. Foi observado também que, quanto maiores as exigências de desempenho técnico, maior a freqüência de lesões.

Fibular Nerve Injury After Small Saphenous Vein Surgery

Superficial nerve injuries are very common during varicose vein surgery. In contrast, deep nerve injuries are rare and reported especially when surgery involves the small saphenous vein (SSV). The deep motor nerves most commonly injured are the tibial nerve and the peroneal nerve, which are directly or indirectly affected by extrinsic compression, stretching, or healing process involvement. In this report, two cases of common fibular nerve injury after SSV stripping are described, including treatment used and patient outcomes. Nerve damage mechanisms, anatomy, and prevention strategies are also discussed. In conclusion, fibular nerve damage may occur during SSV stripping. Preventive measures include careful preoperative ultrasonographic investigation of the anatomy of the vein, determining location of the saphenopopliteal joint, and careful dissection far from fibular nerve and restricted to the popliteal fossa.

Orbitoethmoidal impacted injury by kitchen knife causing abducens nerve palsy

Introduction: Impacted knife injuries in the maxillofacial region are rare and infrequently reported. In cases of injury involving orbit or eye, these reports are even rarer. Discussion: Damage to the orbital contents may result in a rupture of the globe, extraocular muscle injury, lacrimal gland damage, and others. Orbital foreign bodies are not only difficult to detect, and clinical features vary according to its size, characteristics, shape, penetrating method, and site. In this report, a case of abducens nerve palsy after orbitoethmoidal knife injury is presented. © 2010 Springer-Verlag.

Effect of mesenchymal stem cells on movement and urination of rats with spinal cord injury

Cell therapy has frequently been reported as a possible treatment for spinal trauma in humans and animals; however, without pharmacologically curative action on damage from the primary lesion. In this study, we evaluated the effect of administering human adipose-derived stem cells (hADSC) in rats after spinal cord injury. The hADSC were used between the third and fifth passages and a proportion of cells were transduced for screening in vivo after transplantation. Spinal cord injury was induced with a Fogarty catheter no. 3 inserted into the epidural space with a cuff located at T8 and filled with 80 mu L saline for 5 min. The control group A (n = 12) received culture medium (50 mu L) and group B (n = 12) received hADSC (1.2 x 10(6)) at 7 and 14 days post-injury, in the tail vein. Emptying of the bladder by massage was performed daily for 3 months. Evaluation of functional motor activity was performed daily until 3 months post-injury using the Basso-Beattie-Bresnahan scale. Subsequently, the animals were euthanized and histological analysis of the urinary bladder and spinal cord was performed. Bioluminescence analysis revealed hADSC at the application site and lungs. There was improvement of urinary bladder function in 83.3% animals in group B and 16.66% animals in group A. The analysis of functional motor activity and histology of the spinal cord and urinary bladder demonstrated no significant difference between groups A and B. The results indicate that transplanted hADSC improved urinary function via a telecrine mechanism, namely action at a distance.
