ABSTRACT

Iliotibial band syndrome (ITBS), as an overused injury of the lower extremities, has developed into a common cause of lateral knee pain. At present, the treatment of ITBS includes drug therapy, muscle strength training, physical therapy, and surgical treatment. Among these methods, physical therapy, drug therapy, and surgical treatment can only alleviate the symptoms of patients. As a safe and effective treatment, lower limb muscle strength training can improve patients' muscle strength, correct abnormal gait, and reduce the recurrence rate of the disease by paying attention to the dynamic changes of patients' recovery process. At present, the pathogenesis of ITBS remains unclear, and the treatment methods are not unified. It is necessary to further study the biomechanical factors related to the lower extremities and develop more scientific and comprehensive muscle strength training methods.

ABSTRACT

Para promover la reparación y regeneración muscular, se han desarrollado diferentes estrategias, sin embargo, aún no existe un tratamiento único aceptado. Investigaciones relacionan los efectos terapéuticos de la miel en el proceso de cicatrización de heridas de diversas etiologías. Considerando lo anterior, el propósito de este estudio fue evaluar los efectos de una formulación basada en miel nativa (Ulmoplus®) en la reparación de lesiones musculares por incisión quirúrgica. A cinco conejos (Oryctolagus cuniculus) se les realizó una incisión de 20 mm de largo y 3 mm de ancho en la región anterior de cada pierna, atravesando la epidermis, dermis y el músculo tibial anterior, hasta alcanzar el periostio de la tibia. La pierna izquierda de cada animal fue clasificada como grupo sutura (S) y la derecha como grupo sutura más Ulmoplus® (S+U). Posteriormente, al grupo S+U se le aplicó Ulmoplus® en toda la extensión de la herida. Luego, en ambos grupos, la incisión fue suturada con cuatro puntos intradérmicos (vicryl 2/0). Un animal fue considerado como control para obtener imágenes histológicas del músculo tibial anterior sin injuria. A los 10 días post incisión, fueron tomadas las biopsias del músculo y posteriormente fueron procesadas para su observación en microscopio de luz. El estudio se llevó a cabo considerando las recomendaciones de la Guía para el Cuidado y Uso de Animales de Laboratorio. A los 10 días post incisión, las injurias, en ambos grupos de animales, se encontraban cerradas y sin signos de infección. El músculo tibial anterior de los especímenes del grupo S se encontraba en la fase de reparación, con procesos concomitantes de fagocitosis del tejido necrotizado, regeneración de miofibras y formación de tejido conectivo cicatrizal. El músculo tibial anterior de los animales del grupo S+U se encontraba en la fase de remodelación, ya que la arquitectura muscular se evidenciaba restablecida. Ulmoplus®, como coadyuvante en el proceso de cierre de heridas quirúrgicas de músculo esquelético utilizando sutura convencional, es una buena alternativa, ya que acelera el proceso de reparación muscular, y reduce el tejido conectivo cicatrizal.


To promote muscle repair and regeneration, different strategies have been developed, however, there is still no single accepted treatment. Research relates the therapeutic effects of honey in the wound healing process of various etiologies. The aim of this study was to evaluate the effects of native honey formulation (Ulmoplus®) in the repair of muscle injuries by surgical incision. In five rabbits (Oryctolagus cuniculus) were made an incision 20 mm long and 3 mm wide in the anterior region of each leg, crossing the epidermis, dermis and anterior tibial muscle, until reaching the tibia periosteum. The left leg of each animal was classified as a suture group (S) and the right leg as a suture group plus Ulmoplus® (S + U). Subsequently, Ulmoplus® was applied to the entire S + U group throughout the entire length of the wound. Then, in both groups, the incision was sutured with four intradermal points (vicryl 2/0). An animal was considered as a control to obtain histological images of the anterior tibial muscle without injury. At 10 days post incision, muscle biopsies were taken and subsequently processed for observation under light microscopy. The study was carried out considering the recommendations of the Guide for the Care and Use of Laboratory Animals. At 10 days post incision, the injuries, in both groups of animals, were closed and without signs of infection. The anterior tibial muscle of the S group specimens was in the repair phase, with concomitant processes of phagocytosis of the necrotized tissue, myofiber regeneration and formation of scar connective tissue. The anterior tibial muscle of the animals of the S + U group was in the remodeling phase, since the muscular architecture was evidenced restored. Ulmoplus®, as an adjunct in the process of closing surgical wounds of skeletal muscle using conventional suture, is a good alternative, since it accelerates the muscle repair process and reduces scar connective tissue.

ABSTRACT

Introducción: El desgarro muscular agudo es el tipo de lesión más frecuente en actividades deportivas. El interés se ha centrado en buscar modalidades que reduzcan y mejoren el tiempo de curación. El uso de plasma rico en plaquetas ha crecido en los últimos años, pero no estuvo acompañado de suficiente respaldo científico sobre su eficacia. Este estudio intenta recabar, analizar y sintetizar la información publicada para esclarecer los efectos del uso de plasma rico en plaquetas en desgarros musculares agudos, mediante una revisión sistemática y un metanálisis. Materiales y Métodos: Se realizó una revisión bibliográfica sistemática sobre el uso de plasma rico en plaquetas para tratar lesiones musculares agudas. Se llevó a cabo un metanálisis para evaluar los efectos del plasma rico en plaquetas. Resultados: Siete artículos cumplieron los criterios de inclusión (6 ensayos controlados aleatorizados y 1 estudio de cohorte). La media del tiempo hasta el retorno al deporte en el grupo con plasma rico en plaquetas fue de 29 días (rango 10-50.9) y de 35.4 días (rango 22-52.8) en el grupo de control. Cinco de 7 artículos fueron incluidos en el metanálisis y se halló una diferencia significativa en el retorno deportivo con el uso de plasma rico en plaquetas comparado con la terapia convencional (-7.80 días; p = 0,007). No se informaron diferencias en la tasa de recurrencia. Conclusiones: El metanálisis mostró un efecto favorable del plasma rico en plaquetas en comparación con la terapia convencional. Sin embargo, nuestro análisis demostró una heterogeneidad significativa en el estudio. Los resultados deben interpretarse con cautela. Aún no podemos recomendar el plasma rico en plaquetas para tratar desgarros musculares agudos. Nivel de Evidencia: II


Introduction: Acute muscle tear is the most common type of injury in sports activities. There is a present interest in the search of modalities that could shorten and improve healing time. The use of platelet-rich plasma (PRP) has increased over the past years, but such popularity does not count with sufficient scientific support to back up its effectiveness. The purpose of this study is to collect, analyze and summarize the available published data so as to clarify the effects of PRP use on muscle tears through a systematic review and meta-analysis. Materials and Methods: We conducted a systematic review of the literature on the use of PRP for the treatment of acute muscle injuries. A meta-analysis was conducted to evaluate the effects of PRP. Results: A total of 7 papers met the inclusion criteria for analysis: six randomized controlled trials and one cohort study. The overall time to return to sports after PRP treatment was a mean of 29 days (range, 10 to 50.9 days), and in the control groups was a mean of 35.4 days (range, 22 to 52.8 days). The meta-analysis (5 of the 7 papers) showed a significant difference in earlier return to sports with the use of PRP when compared to conventional therapy (-7.80 days; P=0.007). No difference in the recurrence rate was reported. Conclusions: The meta-analysis demonstrated a favorable effect of PRP when compared to conventional therapy. However, our analysis demonstrated significant study heterogeneity. Thus, our findings should be interpreted with caution. We still cannot recommend the use of PRP for the treatment of muscle tears. Level of Evidence: II

ABSTRACT

AIMS: To investigate the effects of resistance exercise and fish oil intake on muscle morphology in Wistar rats. METHODS: Forty-eight animals that performed resistance exercise were initially divided into two groups. One group did not take fish oil and the other group took fish oil. The animals of the second group underwent training and took fish oil for eight weeks. At the end of the last resistance exercise session, the 48 rats were organized into six subgroups of eight each, according to the time gap (12, 24 or 48 hours) elapsed until the gastrocnemius muscle withdrawal procedure. At each established time after the last resistance exercise session, the gastrocnemius muscle was removed for morphological analysis. RESULTS: Skeletal muscle cells of the animals that did not receive fish oil presented higher scores of edema, especially those from the groups that had their muscles withdrawn at 24 and 48 hours of time gap. As for the group that took fish oil, we observed a smaller amount of inflammatory infiltrate and reduced areas of necrosis compared to animals that exercised without the use of fish oil, at all post-exercise time gaps. CONCLUSIONS: Fish oil intake attenuated morphological changes in muscle tissue after high-intensity exercises


OBJETIVOS: Investigar os efeitos do exercício resistido e da ingestão de óleo de peixe na morfologia da fibra muscular em ratos Wistar. MÉTODOS: Quarenta e oito animais realizaram exercício resistido e foram divididos inicialmente em dois grupos. Um dos grupos não recebia óleo de peixe e o outro grupo ingeria o óleo de peixe. Os animais do segundo grupo realizaram o treinamento e ingeriram o óleo de peixe por um período de oito semanas. Ao final da última sessão de exercício resistido os animais foram organizados em seis subgrupos de oito cada, segundo o intervalo de tempo (12, 24 e 48 horas) transcorrido até o procedimento de retirada do músculo gastrocnêmio. Em cada tempo determinado após a última sessão de exercício resistido, o músculo gastrocnêmio foi retirado para análise morfológica. RESULTADOS: As células do músculo esquelético dos animais que não receberam óleo de peixe apresentaram escores maiores de edema, especialmente as dos grupos que tiveram os músculos retirados em 24 e 48 horas. No grupo que ingeriu o óleo de peixe observou-se menor quantidade de infiltrado inflamatório e áreas de necrose reduzidas em comparação com os animais que se exercitavam sem o uso de óleo de peixe, em todos os intervalos de tempo pós-exercício. CONCLUSÕES: A ingestão de óleo de peixe atenuou as alterações morfológicas no tecido muscular após exercícios de alta intensidade.

ABSTRACT

This study describes aspects of infections caused by the myxosporidian Kudoa orbicularis in filter-feeding cichlids, Chaetobranchopsis orbicularis, caught in the Arari River in the municipality of Cachoeira do Arari, on Marajó Island, Pará, Brazil. The parasite forms pseudocysts scattered throughout the striated epaxial and hypaxial muscles. Samples embedded in paraffin were analyzed histologically using hematoxylin-eosin, Gömöri, Ziehl-Neelsen, and Giemsa staining. Necropsy of the C. orbicularis specimens revealed that 100% (50/50) were infected with K. orbicularis. The specimens presented grossly abnormal muscle texture, resulting in extensive inconsistencies and weakness. Progressive softening of the muscles was observed during necropsy, indicating the rapid enzymatic autolysis of the tissue. The parasite found in the muscle tissue of C. orbicularis was identified as K. orbicularis, with clinical signs of disease being observed in the fish. The necropsy revealed extensive damage to the host organism, with well-established fibrocystic infections in the muscle fibers, associated with post mortem myoliquefaction.(AU)


O presente estudo descreve os aspectos histopatológicos de infecção causada por mixosporídio da espécie Kudoa orbicularis, o qual forma pseudocistos dispersos em toda a musculatura estriada esquelética, epi e hipoaxial, de Chaetobranchopsis orbicularis, capturados no Rio Arari, município de Cachoeira do Arari, Ilha do Marajó, Pará. Foram realizadas as técnicas histológicas de impregnação em parafina, utilizando-se as colorações de hematoxilina-eosina, Gomori, Ziehl-Neelsen e Giemsa. As análises necroscópicas dos espécimes de C. orbicularis revelaram 100% (50/50) de infecção por K. orbicularis. Os espécimes apresentavam macroscopicamente musculatura com características anormais de textura, se mostrava inconsistente e frágil. Durante a necropsia, pôde ser observado um progressivo amolecimento da musculatura, o que demonstra um rápido processo enzimático autolítico. Com base nos achados descritos neste trabalho, caracterizou-se uma infecção da musculatura de C. orbicularis por K.orbicularis, com demonstração de sinais clínicos de doença no peixe; os achados necroscópicos mostraram danos ao organismo hospedeiro, com instalação de infecção fibrosística nas fibras musculares, associada com uma mioliquefação post mortem.(AU)

ABSTRACT

En el presente los desgarros musculares son una causa muy frecuente de lesión en la práctica deportiva. Según los estudios actuales, un 30% de las lesiones en atletas afecta los músculos, siendo particularmente comunes a nivel de los isquiotibiales, el recto anterior de los cuádriceps, los gemelos y los aductores. El diagnóstico se realiza en forma sencilla mediante un estudio ecográfico. Sin embargo, existe un número importante de lesiones musculares de localización profunda e infrecuente, que pueden pasar inadvertidas en la ecografía y que causan largos períodos de inactividad para el deportista. La resonancia magnética (RM), por su resolución anatómica y capacidad multiplanar, es el método de elección para el estudio de este tipo de afecciones, ya que permite descartar otras patologías de similar presentación clínica y realizar un diagnóstico específico. En este artículo describimos los desgarros musculares de localización inusual, particularmente los de localización pelviana, evaluando también la pared torácica, abdominal y miembros superiores e inferiores. En todos los casos, se usaron equipos de alto campo 1.5 y 3 Tesla.


Muscle injuries are currently particularly frequent among people who participate in sports. Current studies show that 30% of injuries in athletes affect muscles, with hamstrings, quadriceps, gastrocnemius, and adductors being particularly prevalent. The diagnosis is easily made with an ultrasound study. However, there are a significant number of muscle injuries, considered uncommon, that may be not be detected by ultrasound, mainly because of their depth, and could be responsible for long periods of inactivity for the sportsman. Magnetic resonance imaging (MRI), with a better anatomical resolution and multiplanar capability, is the method of choice for detecting the precise location and severity of the injury and can establish their severity. The aim of this article is to review muscle tears of unusual location, particularly in the pelvic area, but also evaluating the chest wall, abdomen, and upper and lower limbs. All patients were evaluated by 3 and 1.5 Tesla MRI units.

ABSTRACT

A necessidade de opções terapêuticas para lesões musculares, cada vez mais fre quentes entre os esportistas, fundamentou este estudo experimental, cujo objetivo foi avaliar os efeitos histológicos do plasma rico em plaquetas (PRP) no reparo do tecido mus cular de ratos. Métodos: O PRP foi obtido por dupla centrifugação do sangue de cinco animais. Em 30 ratos, foi produzido um trauma no terço médio do ventre do músculo gastrocnêmio de cada mem bro traseiro. Essas lesões não receberam tratamento em seis ratos (12 patas). Em 24 ratos, injeções intralesionais de soro fisiológico a 0,9% e de PRP foram aplicadas nas patas esquer das e direitas, respectivamente. Amostras do tecido tratado e não tratado foram avaliadas histologicamente sete e 21 dias após os procedimentos. Resultados: A quantidade de colágeno nas lesões tratadas com PRP foi significativamente menor do que a das demais lesões na avaliação feita sete dias após o procedimento, mas se equiparou à dos demais grupos na avaliação feita no 21° dia. Houve aumento significativo (p < 0,001) na quantidade de colágeno do sétimo para o 21° dia nas lesões tratadas com PRP, o que não ocorreu nas lesões tratadas de outra forma. O processo inflamatório se mostrou mais intenso nas lesões tratadas com PRP em comparação com as lesões dos outros grupos de tratamento na avaliação feita sete dias após o procedimento; todavia, os aspectos mor fológicos dessas lesões se mostraram similares ao das lesões não tratadas 21 dias após o procedimento. Conclusão: OPRP promoveu completa restituição tecidual entre o sétimo e o 21° dia em lesões musculares experimentais.


The need for therapeutic options for muscle injuries, which are increasingly frequent among sports practitioners, was the motivation for this experimental study, which had the aim of evaluating the histological effects of platelet-rich plasma (PRP) on repairs to muscle tissues of rats. METHODS: PRP was obtained by means of double centrifugation of blood from five animals. In 30 rats, an injury was produced in the middle third of the belly of the gastrocnemius muscle of each hind limb. These injuries did not receive any treatment in six rats (12 legs). In 24 rats, 0.9% physiological serum was injected into the injury in the left leg and PRP into the injury in the right leg. Samples from the treated and untreated tissue were evaluated histologically 7 and 21 days after the procedures. RESULTS: The quantity of collagen in the injuries treated with PRP was significantly lower than that in the other injuries, in the evaluation made 7 days after the procedure, but it became equal to the other groups in the evaluation done on the 21st day. There was a significant increase (p < 0.001) in the quantity of collagen from the 7th to the 21st day in the injuries treated with PRP, but this was not seen in the injuries treated using other methods. The inflammatory process was shown to be more intense in the injuries treated with PRP than in the injuries of the other treatment groups, in the evaluation done 7 days after the procedure. However, the morphological aspects of these injuries were seen to be similar to those of the untreated injuries, 21 days after the procedure. CONCLUSION: PRP promoted complete tissue restitution between the 7th and 21st days in experimental muscle injuries.

ABSTRACT

Avaliar a influência da suplementação oral com arginina na regeneração de lesão por estiramento do músculo tibial anterior de ratos. MÉTODO: Usaram-se 24 ratos Wistar (492,5 ± 50,45 gramas), induzidos com lesão por estiramento dos músculos tibiais anteriores e separados em três grupos com oito ratos cada. No grupo não tratado (GNT), após a indução das lesões, os ratos foram observados por 24 horas, nos grupos simulação (GS) e arginina (GA) receberam, por gavagem diariamente, respectivamente solução salina isotônica e solução de arginina, durante sete dias. Ao término dos períodos foram coletadas amostras de sangue para as avaliações séricas de creatina-quinase (CK), desidrogenase lática (LDH), aspartato-aminotransferase (AST) e proteína C reativa (PCR). Foram ressecados os músculos tibiais anteriores (direitos e esquerdos) para avaliações histopatológicas das lesões musculares e pesquisa de edema, hemorragia, desorganização ou alteração morfométrica das fibras musculares. E foi feita a reparação tecidual, para pesquisa da proliferação de tecido adiposo, angiogênese e fibras colágenas. Empregaram-se os testes ANOVA e tde Student com p ≤ 0,05 para significação estatística. RESULTADOS: Nas avaliações séricas o GA mostrou valores menores nas dosagens de CPK e maiores nas dosagens de AST. Nas avaliações histopatológicas, no GNT foram evidenciados edema e hemorragia compatíveis com lesões por estiramento, no GS edema, hemorragia com proliferação de tecido adiposo e fibras colágenas e no GA. Além dos achados do GS destacou-se intensa angiogênese. CONCLUSÃO: A suplementação oral com arginina não causou alterações metabólicas importantes que contraindiquem seu uso e induziu angiogênese durante a reparação de lesões musculares por estiramento.


To evaluate the influence of oral supplementation with arginine on regeneration of injuries due to straining of the anterior tibial muscle of rats. METHODS: Twenty-four Wistar rats of weight 492.5 ± 50.45 g were used. Injuries were induced through straining the anterior tibial muscles. The rats were separated into three groups of eight rats each. In the untreated group (UTG), after induction of injuries, the rats were observed for 24 h. In the simulation group (SG) and the arginine group (AG) respectively, the rats received isotonic saline solution and arginine solution via direct gavage, over a seven-day period. At the end of the period, blood samples were collected for serum evaluations of creatine kinase (CK), lactic dehydrogenase (LDH), aspartate aminotransferase (AST) and C-reactive protein (CRP). The right and left anterior tibial muscles were resected for histopathological evaluations on the muscle injuries, investigating edema, hemorrhage and disorganization or morphometric alteration of the muscle fibers. The tissue repair was investigated in terms of proliferation of adipose tissue, angiogenesis and collagen fibers. The ANOVA and Student's tmethods were used and p≤ 0.05 was taken to be statistically significant. RESULTS: In the serum evaluations, the AG showed lower CK assay values and higher AST values. In the histopathological evaluation, the UTG presented edema and hemorrhage compatible with injuries due to strain; the SG presented edema and hemorrhage with proliferation of adipose tissue and collagen fibers; and the AG presented not only the findings of the SG but also, especially, intense angiogenesis. CONCLUSION: Oral supplementation with arginine did not cause any significant metabolic alterations that would contraindicate its use and it induced angiogenesis during the repair of muscles injured due to strain.

ABSTRACT

Estiramento muscular e outras desordens musculoesqueléticas são as principais causas que desabilitam atletas e praticantes de atividades físicas. Seu tratamento inclui AINES que desencadeiam vários efeitos adversos. Objetivo: o objetivo do estudo foi avaliar o efeito dos tratamentos com Laserterapia de Baixa Potência e do anti-inflamatório diclofenaco, tanto individualmente quanto combinados (laser + aplicação por vias tópica ou intramuscular de diclofenaco) em aspectos histológicos no modelo experimental de lesão muscular por estiramento controlado em ratos. Materiais e Métodos: a lesão por estiramento foi induzida, por sobre carga, no músculo tibial anterior de ratos (n=6). O grupo controle não recebeu tratamento, grupos lesados receberam um único tratamento com diclofenaco através das vias tópica ou intramuscular, irradiação com laser (3 J, 830 nm, 100 mW) ou os dois tratamentos conjuntamente, laser e diclofenaco, totalizando seis grupos experimentais. Os tratamentos foram realizados 1 hora após a lesão. O músculo tibial foi removido para análise histológica, três horas após a indução da lesão e também seis horas após indução. Resultados e discussão: a avaliação histológica demonstrou uma melhor organização estrutural do tecido muscular, células bem delineadas e menor quantidade de fibras fragmentadas e menor descontinuidade de acidofilia nos grupos tratados com laser e diclofenaco, nas duas vias de aplicação, tanto no período de 3 horas quanto no de 6 horas após a lesão. Conclusão: a irradiação do laser de baixa potência conjuntamente ao diclofenaco tópico e intramuscular melhorou aspectos histológicos do tecido muscular, após lesão por estiramento, na fase aguda quando comparado com os demais tratamentos...

Objective: the objective of the study the effect of treatments with Low Power Laser (LPL) Therapy and the anti-inflammatory diclofenac, both individually and combined (LPL + intramuscular or topical application of diclofenac pathways) in histological aspects in an experimental model was to evaluate muscle injury in rats controlled stretch. Materials and Methods: the injury was induced by muscle stretch, overload, the tibialis anterior muscle of rats (n = 6). The control group received no treatment, injured groups received a single treatment with diclofenac through the anti-inflammatory topical or intramuscular (AT and AIM), irradiation with LPL (3 J 830 nm, 100 mW), or the two treatments together, LPL and diclofenac (LPL/LPL or AT/AIM), totaling six experimental groups. All treatments were performed 1 hour after the injury. The right anterior tibial muscle was removed for histological analysis, within 3 hours after induction of the lesion and also 12 hours after induction. Results and discussion: histological evaluation in this study showed a better estructural organization of muscle tissue, cells and less well defined amount of fragmented fibers in the group treated with LPL and LPL AT + 3J 3J + AIM in both the 3-hour period and in 6 hours following injury. Conclusion: treatment with LPL jointly to the topic and intramuscular diclofenac improved the histological aspects of muscle tissue after stretch injury in the acute phase compared with the other treatments...

ABSTRACT

Los desgarros musculares son lesiones frecuentes que pueden producir ausencia deportiva y altas tasas de recurrencia. Las tasas de prevalencia de las lesiones musculares se han reportado entre 12% y 16% y las tasas de repetición de la lesión puede ser tan alta como 34% después de 1 año. Estudios realizados en animales sugieren que los factores de crecimiento y las citoquinas liberadas por las plaquetas podrían acelerar el proceso natural de curación. Sin embargo. el efecto del Plasma Rico en Plaquetas (PRP) en el tratamiento de los desgarros musculares no está bien definido ya que insuficiente cantidad de estudios están disponibles en la literatura. Por lo que el objetivo de nuestro trabajo es reportar los efectos de la inyección intralesional de PRP en el tiempo de retorno al deporte y el índice de recurrencia en los desgarros musculares agudos grado 2 en deportistas de nivel recreacional y competitivo. Material y Métodos: Setenta y cinco pacientes diagnosticados con desgarro muscular agudo grado 2 fueron asignados mediante randomización a Grupo l (PRP+ Programa de rehabilitación) y Grupo 2 (Programa de rehabilitación únicamente)...

ABSTRACT

Objective: To evaluate the management, procedures and perspectives of sports physicians and orthopedists in Brazil with regard to diagnosing and treating muscle injuries. Methods: A questionnaire containing 20 questions relating to the topic of muscle injury was applied to sports physicians and orthopedists during the Second Brazilian Congress of Arthroscopy and Sports Traumatology, in 2013. Results: Completely answered questionnaires were received from 168 sports physicians and orthopedists. Doctors from all regions of Brazil with a mean of 11 years of experience of treating muscle injuries were interviewed. Lower limbs were affected in 97% of the cases, particularly the quadriceps, adductor and sural triceps. The injury occurred during the eccentric phase in 62% of the interviews; 39% underwent ultrasound examination and 37% magnetic resonance imaging (MRI) for the injury to be diagnosed. Medication, rest and cryotherapy during the acute phase (87.5%) and medication, rest and physiotherapy during treatment of the injury (56%) were the prevalent options. The criteria for returning to sports were very subjective and disparate among the options presented, and most of the interviewees had already used some therapy that was adjuvant to traditional methods. Conclusion: The number of muscle injuries treated per year was greater than 30, independent of whether in the public or private sector. These injuries occurred mainly at the muscle–tendon junction, in the lower limbs and during the eccentric phase of muscle contraction. Ultrasound was the examination most performed, while MRI was considered ideal. For most of the interviewees, the preferred treatment involved rest, medication and physiotherapy. In addition, 52% believed that platelet-rich plasma was an efficient treatment and 42% said that they had already used it...


Objetivo: Avaliar as condutas, os procedimentos e as perspectivas do médico do esporte e ortopedista do Brasil no diagnóstico e no tratamento de lesões musculares. Métodos: Questionário com 20 questões relacionadas ao tema lesão musculares. Foi aplicado em médicos do esporte e ortopedistas durante o II Congresso Brasileiro de Artroscopia e Traumatologia do Esporte, em 2013. Resultados: Responderam completamente o questionário 168 médicos do esporte e ortopedistas. Foram entrevistados médicos de todas as regiões do Brasil, com média de 11 anos de experiência no tratamento da lesão muscular. Membros inferiores são acometidos em 97% dos casos, principalmente quadríceps, adutor e tríceps sural. A lesão ocorre na fase excêntrica para 62% dos entrevistados, 39% fazem ultrassom (USG) e 37% ressonância magnética (RM) para diagnóstico da lesão. Medicação, repouso e crioterapia na fase aguda (87,5%) e medicação, repouso e fisioterapia durante o tratamento da lesão (56%) são as opções prevalentes. Os critérios de retorno ao esporte foram bastante subjetivos e díspares entre as opções apresentadas e a maioria dos entrevistados já usou alguma terapia adjuvante às tradicionais. Conclusão: O número de lesões musculares tratadas anualmente é superior a 30, independentemente de se no setor público ou privado. Ocorre principalmente na junção miotendínea, nos membros inferiores e na fase excêntrica da contração muscular. O USG é o exame mais feito e a RM o considerado ideal. Para a maioria dos entrevistados o tratamento de escolha envolve repouso, medicação e fisioterapia. Além disso, 52% acreditam na eficiência do plasma rico em plaquetas (PRP) e 42% referem já tê-lo usado...

ABSTRACT

En la actualidad en Cuba algunos adolescentes y jóvenes, en su afán de aumentar rápido el tamaño de sus músculos se están inyectando aceite de soya de uso doméstico, lo cual les ha conducido a graves lesiones que incluso han puesto en peligro sus vidas. El objetivo de este trabajo es presentar una nueva afección, mostrar las características de las lesiones y divulgar los resultados con fines educativos y de prevención. Se presentaron 3 casos sobre los efectos nocivos de la inyección de aceite de uso doméstico en músculos, en pacientes ingresados en el Hospital Pediátrico Eliseo ¨Noel¨ Caamaño de Matanzas de diciembre 2010 a mayo 2011. Sus características clínicas son gran aumento de volumen en músculos inyectados, el calor, rubor, intenso dolor e impotencia funcional con toma del estado general. El tratamiento quirúrgico fue incisión, desbridamiento y drenaje, que mostró abundante aceite, pus, sangre y fibras musculares necrosadas; proceder que se debe realizar múltiples veces. Las lesiones no ocurren de inmediato sino con intervalos variables, no al unísono sino desorganizadamente, con gran dificultad para su cicatrización. Se utilizó además tratamiento antibiótico de amplio espectro y cámara hiperbárica. Se concluye que la utilización de aceite de uso doméstico trae graves consecuencias a la salud, como la sepsis y necrosis severa de los músculos, hepatitis C, septicemia y peligro para la vida de quienes lo usan(AU)


At present, some teenagers and young people in Cuba, in their desire to quickly increase the size of their muscles, are injecting soybean oil for domestic use, which has led them to serious injuries and even risk to their lives. The aim of this work is to present this new condition, to show the characteristics of the lesions and spread the results for education and prevention. We presented three cases on the adverse effects of oil injection into muscles in patients who were admitted to the Paediatric Hospital Eliseo ¨Noel¨ Caamaño of Matanzas from December 2010 to May 2011. Their clinical features were a high increase in volume of the injected muscles, heat, redness, intense pain and functional impotence with general malaise. The surgical treatment consisted on the incision, debridement and drainage which showed abundant oil, pus, blood and necrotic muscle fibres, procedure that had to be performed many times. The lesions did not occur immediately, but with varying intervals and not in unison but in a disorganized form with great difficulty in healing. Treatment with broad-spectrum antibiotic was also used as well as hyperbaric chamber. We conclude that the use of domestic oil provokes serious consequences to health such as sepsis and serious muscle necrosis, Hepatitis C, septicaemia and danger to the lives of those who use it(AU)


Afin de développer rapidement leur masse musculaire, les adolescents et jeunes gens à Cuba ont l'habitude de s'injecter par voie intramusculaire de l'huile de soya à usage domestique, résultant en graves lésions et mettant même leurs vies en péril. Le but de ce travail est de présenter cette nouvelle affection, de montrer les caractéristiques des lésions, et de diffuser les résultats à des fins éducative et préventive. Les cas des trois jeunes patients hospitalisés à l'hôpital pédiatrique Eliseo Noel Camaño, à Matanzas, depuis décembre 2010 jusqu'à mais 2011, montrant les effets néfastes de l'injection intramusculaire de l'huile à usage domestique, sont présentés. Les caractéristiques cliniques comprennent une grande augmentation du volume des muscles injectés, chaleur, douleur intense, rougeur, impotence fonctionnelle, et malaise générale. Le traitement chirurgical a consisté en incision, débridement et drainage, montrant une quantité excessive d'huile, pus, sang et fibres musculaires nécrosées; cette opération a été répétée plusieurs fois. Les lésions ne se produisent pas d'immédiat, mais en intervalles variables et de façon désorganisée, rendant la cicatrisation difficile. Les patients ont été aussi traités par des antibiotiques à large spectre et par oxygénothérapie hyperbare. On conclu que l'emploi de l'huile à usage domestique a des conséquences nuisibles pour la santé telles que l'infection et la nécrose sévère des muscles, hépatite C, septicémie et danger pour la vie de ceux qui l'utilisent(AU)

ABSTRACT

Due to the anatomical distribution and function, striated muscle is susceptible to injury especially traumatic requiring imaging methods for diagnosis, the degree of disease and establish the extent possible recovery time. Ultrasonography is a method that has gained an important place in the evaluation of muscle to be safe, affordable, and by allowing static and dynamic assessment of the muscle. The current classification of muscle injuries seen by Ultrasonography has limitations because it does not allow an adequate correlation between the percentage of condition and prognosis.


Debido a la distribución anatómica y función, el músculo estriado es susceptible de sufrir lesiones sobre todo traumáticas que requieren de métodos de imagen para determinar el diagnóstico, el grado de afección y establecer en la medida de lo posible el tiempo de recuperación. La Ultrasonografía es un método que ha ido ganando un lugar preponderante en la evaluación del músculo por ser inocua, de bajo costo, así como por permitir una evaluación estática y dinámica del músculo. La clasificación actual de lesiones musculares vistas por Ultrasonografía tiene limitantes porque no permite fundamentar una adecuada correlación entre el porcentaje de afección y el pronóstico.

ABSTRACT

In Mexico, medicinal plants are widely used. The use of Randia aculeata by healers against snakebites has never been scientifically tested in relation to possible effects on blood parameters and muscle tissue damage. Interviews were carried out in Jamapa, Veracuz, Mexico, with local residents to collect information about the traditional use of Randia aculeata. In this locality, seven pieces of fruit from the plant are mixed in a liter of alcohol, and then administered orally against snakebites. By using histological techniques and a murine model, we explored its cytoprotective properties against the effects of Crotalus simus and Bothrops asper venoms. Possible protections provided by the plant against tissue damage to skeletal and cardiac muscles and against the typical loss of red blood cells were analyzed. Randia aculeata caused an increase in microhematocrit and total hemoglobin, parameters that are often decremented in association with the loss of red blood cells, which is a characteristic effect of animal venom. Randia aculeata was also shown to protect against the lowering of platelet levels caused by Bothrops asper venom. Finally, Randia aculeata produced a partial inhibition of necrosis following administration of snake venom in skeletal and myocardial muscles. The present results provide solid evidence for the traditional use of Randia aculeata against snakebites, as demonstrated by protection against muscular tissue damage and the diminution of red blood cells.

ABSTRACT

Estudos realizados na área de saúde fazem crer que os ácidos graxos poli-insaturados ômega-3 (AGPI-n3) derivados de óleo de peixe, possam ser úteis em meio atlético. Visando um melhor esclarecimento, essa revisão tem como objetivo reunir e abordar evidências acerca do uso da suplementação com AGPI-n3 no exercício físico e os efeitos dessa suplementação, além de contribuir tanto para o conhecimento quanto para a compreensão sobre o tema. Desta forma foi realizada uma pesquisa bibliográfica, que revisou periódicos nacionais e internacionais em banco de dados, livros, monografias, dissertações e teses. Há indícios de que o uso dos AGPIn3 possam atenuar os efeitos do processo inflamatório em lesões musculares por ajudarem na modulação e liberação de citocinas pró-inflamatórias. .


Abstract: Studies in health survey suggest that the polyunsaturated fatty acids omega-3 (PUFA-n3) derived from fish oil, may be useful in athletic environment. For a better explanation, the aim of this review is bring together and address the evidence regarding the use of supplementation PUFA-n3 inthe exercise and the effects of it, as well as contributing to both knowledge and understanding of the topic. Thus was performed a literature search that reviewed national and international journals in the database, books, monographs, dissertations and theses. There is evidence that the use of PUFAn3 can mitigate the effects of inflammation in muscle injuries by helping in the modulation andrelease of inflammatory cytokines.

ABSTRACT

O triatlo é um esporte de destaque e ampla participação mundial. Incorpora três diferentes modalidades de endurance - natação, ciclismo e corrida - dentro de um único evento. Há uma variedade de distâncias sobre as quais os eventos de triatlo são realizados, sendo a prova de ultradistância (ironman) a mais extensa. Autores diversos já relataram a ocorrência de lesões após esforço intenso, seja diretamente, através de alterações histológicas no sarcômero, ou indiretamente, pela quantificação da concentração de proteínas musculares específicas (biomarcadoras de lesão) no plasma. Entre esses marcadores de lesão muscular destacam-se a mioglobina e a creatina cinase. Efetivamente, a creatina cinase é o indicador bioquímico mais utilizado na literatura como indicador da ocorrência de lesão muscular. Dentro desse contexto justifica-se o objetivo do presente trabalho que visa verificar o efeito do exercício nas concentrações séricas de creatina cinase em triatletas de ultradistância frente a um período de competição. Para tanto, foram avaliados os dados das concentrações séricas de CK de 10 atletas que participaram da prova do Ironman Brasil de 2007. As análises sanguíneas foram realizadas em cinco períodos distintos: 19 dias antes da prova do ironman (CK1), 48 horas antes da prova (CK2), imediatamente após (CK3), cinco dias após (CK4) e 12 dias depois da prova (CK5). Os resultados apontaram aumento significativo nas concentrações de CK nos períodos 3 e 4 em relação aos demais períodos avaliados. Estas alterações evidenciam a influência do exercício exaustivo sobre as concentrações de CK, revelando a possibilidade de desenvolvimento de lesões musculares durante essa competição. Este fato reforça a importância do monitoramento de biomarcadores, como a CK, que permite a treinadores e atletas ajustarem suas cargas de treinamento para aumentar os benefícios do treinamento e para evitar o supertreinamento, melhorando o desempenho, a saúde e a qualidade de vida do atleta.


Triathlon is a popular sport with world wide participation. It combines three different endurance modalities - swimming, cycling and running - within a single event. There is a variety of distances on which triathlon events are made, the Ironman race being the longest. Many authors have already reported injury occurrence after intense exertion, either directly, through histological sarcomere alterations, or indirectly, over the quantification of specific muscle proteins concentration (injury biomarkers) in the plasma. Among these markers of muscle injury, Myoglobin and Creatine Kinase stand out. In fact, creatine kinase is the most used biochemical indicator of muscle injury occurrence. Within this context, it is justified the purpose of this study, that intends to verify exercise effects on serum levels of creatine kinase in ultra-distance triathletes in the course of a competition period. Serum levels of CK from 10 triathletes who competed in the Ironman Brazil event, 2007 were evaluated. Blood analyses were done at five distinct periods: 19 days before Ironman Brazil competition (CK1), 48 hours before it (CK2), immediately after it (CK3), five days after the competition (CK4) and 12 days after the event (CK5). The results showed significant increase on CK concentrations at periods 3 and 4, when compared to the other evaluated periods. These alterations evidence the influence of the Ironman competition exhaustive exercise over the CK concentrations, revealing the possibility of muscle injuries development during the event. This fact enhances the importance of biomarkers' monitoring, like CK, that allow coaches and athletes to adapt training loads to increase their benefits and to avoid overtraining, improving performance, health and quality of life.

ABSTRACT

As características macroscópicas da origem do músculo deltoide foram estudadas em 12 ombros de cadáveres. A origem acromial anterior e lateral do deltoide foi dissecada e analisada macroscopicamente com auxílio de computação gráfica. Determinamos as medidas dos diâmetros ântero-posterior do acrômio e do deltoide e suas respectivas áreas e, a seguir, realizamos simulações por computação de descompressões subacromiais de 4, 6 e 8 mm. As descompressões subacromiais simuladas de 8 mm, 6 mm e 4 mm desinserem 34,7%, 32 % e 29,1% da área de origem do deltoide, respectivamente. Concluímos que os diâmetros ântero-posteriores e as áreas do acrômio e deltoide possuem diferenças estatísticas significantes. Os diâmetros lateromediais do acrômio em relação ao deltoide não apresentam diferenças estatísticas, assim como a área do deltoide remanescente após uma descompressão subacromial de 4 mm, quando comparada com a área do acrômio.
