Reduction of recurrent tendinitis scar using autologous mesenchymal stem cells derived from adipose tissue from the base of the tail in Holsteiner horses (Equus ferus caballus) / Reducción de la cicatriz de tendinitis recidivante mediante células madre mesenquimales autólogas derivadas de tejido adiposo de la base de la cola en equinos Holsteiner (Equus ferus caballus)

As a result of their intense physical activity, racehorses suffer high tendon stress which may result in various pathologies. One of these is tendonitis in the tendon of the superficial digital flexor muscle (TSDFM). Conventional treatment with rest, has not shown to be very effective, and regenerative medicine through the application mesenchymal stem cells appears to be a promising therapy. The objective of this work was to assess the effect of the application of autologous MSC on reduction of the scar length in recurrent TSDFM tendinitis in Holsteiner horses, using image analysis. This study included two groups of five animals each: A control group that received conventional treatment (CG) and an experimental group which was also treated with intralesional injections of MSC (EG). Scar evolution was assessed by echographic analysis, with measurements taken of the scar length over a four month period; the length at month zero, was taken as the initial value of 100 %. During the first month, the mean scar length diminished to 81.14 % (EG) and 95.85 % (CG); after the second month, lengths were 64.4 % (EG) and 92.3 % (CG); following the third month lengths were 51.92 % (EG) and 87.42 % (CG); finally at the end of the fourth month the lengths recorded were 26.7 % (EG) and 83.92 % (CG). These results show that treatment with autologous MSC helps TSDFM scar length was significantly reduced, as compared to conventional treatment.

Reducción de la cicatriz de tendinitis recidivante mediante células Madre mesenquimales autólogas derivadas de tejido adiposo de la base de la cola en equinos Holsteiner (Equus ferus caballus). En equinos deportistas, la actividad física intensa ocasiona gran estrés en los tendones, pudiendo ocasionar diversas patologías como la tendinitis del tendón del músculo flexor digital superficial (TMFDS). El tratamiento convencional con reposo es poco eficaz, siendo la medicina regenerativa a través de la aplicación de células madres mesenquimáticas (MSC) una promisoria terapia. El objetivo de este trabajo, fue evaluar el efecto de la aplicación de MSC autólogas, sobre la reducción de la longitud de la cicatriz en tendinopatías recidivantes del TMFDS en equinos Holsteiner, a través del análisis de imagen. Este estudio conto con dos grupos de cinco animales cada uno, el grupo control mantuvo el tratamiento convencional (GC) y el grupo experimental fue tratado adicionalmente con inyección interlesional de MSC (GE). El análisis ecográfico permitió evaluar la evolución de la cicatriz, a través de la medición de su longitud durante los cuatros meses, tomando la longitud del mes cero como la medición inicial del 100 %. Durante el primer mes, la longitud de la cicatriz se redujo a un 81,14 % (GE) y 95,85 % (GC), al segundo mes la longitud fue de un 64,4 % (GE) y de 92,3 % (GC), al tercer mes, la longitud fue de 51,92 (GE) y un 87,42 (GC), finalmente al cuarto mes la longitud fue de 26,7 % (GE) y del 83,92 % (GC). Estos resultados muestran que el tratamiento con MSC autólogas favorece a la disminución de la longitud de la cicatriz del TMFDS de forma significativa respecto al tratamiento convencional.

Laser Photobiomodulation in the acute inflammatory response of the calcaneal tendon injury in rats exposed to cigarette smoke / Fotobiomodulação Laser na resposta inflamatória aguda em lesão do tendão calcâneo em ratos expostos a fumaça de cigarro / Fotobiomodulación láser en la respuesta inflamatoria aguda en lesión del tendón calcáneo en ratones expuestos a humo de cigarrillo

ABSTRACT Nicotine delays the healing process and increases the levels of myeloperoxidase (MPO), an enzyme that plays a key role in the production of reactive oxygen species during the inflammatory process. Laser Photobiomodulation (PBM) is one of the most used electrophysical agents in the treatment of the calcaneal tendon, however, its effects on MPO activity need to be further elucidated. This study aimed to evaluate the effects of laser PBM on MPO activity after inflicting an injury to the calcaneal tendon of rats exposed to cigarette smoke. Thirty-four male Wistar rats with 90 days of age were used. After 14 days of exposure to cigarette smoke, the animals were divided into three experimental groups: control group (CG, n=12), not submitted to injury or treatment; sham group (ShG, n=10), submitted to partial calcaneal tendon injury and laser PBM simulation; and laser PBM group (PBMG, n=12), submitted to partial calcaneal tendon lesion and treated with laser PBM within the first minute after injury. PBM decreased MPO activity levels in PBMG compared to ShG (CG: 1.38±0.69pg/ml; ShG: 3.78±1.09pg/ml; PBMG: 2.58±0.93pg/ml; p<0.005). In conclusion, applying laser PBM immediately after inflicting damage to the calcaneal tendon attenuates acute inflammatory activity in rats exposed to cigarette smoke.

RESUMO A nicotina retarda o processo de cicatrização e eleva os níveis da enzima mieloperoxidase (MPO), a qual possui um papel fundamental na produção de espécies reativas de oxigênio durante o processo inflamatório. A fotobiomodulação laser (FBM) é um dos agentes eletrofísicos mais utilizados no tratamento do tendão calcâneo, no entanto, os seus efeitos sobre a atividade da MPO carecem de maior elucidação. Este estudo objetivou avaliar os efeitos da FBM sobre a atividade da MPO, após lesão do tendão calcâneo em ratos expostos à fumaça de cigarro. Foram utilizados 34 ratos Wistar, machos, com 90 dias de vida. Após 14 dias de exposição à fumaça de cigarro, os animais foram divididos em três grupos experimentais: grupo controle (GC, n=12), não submetido à lesão ou tratamento; grupo sham (GSh, n=10), submetido à lesão parcial do tendão calcâneo e a simulação da FBM laser; grupo FBM laser (GFBM, n=12), submetido à lesão parcial do tendão calcâneo e tratados com FBM laser, no primeiro minuto após a lesão. A FBM diminuiu os níveis de atividade da MPO no GFBM em comparação ao GSh (GC: 1,38±0,69 pg/ml; GSh: 3,78±1,09pg/ml; GFBM: 2,58±0,93pg/ml; p<0,005). Conclui-se que a FBM laser aplicada imediatamente após lesão do tendão calcâneo, atenua a atividade inflamatória aguda em ratos expostos à fumaça de cigarro.

Uso de plasma rico en plaquetas para el tratamiento de tendinopatía rotuliana / Platelet-rich plasma in patellar tendinopathy

Objetivo: La tendinopatía rotuliana (TR) es una patología muy frecuente en la población deportista. Se trata de una patología de origen multifactorial en la que se produce un proceso degenerativo sobre el tendón rotuliano. Habitualmente es de muy difícil manejo y con tendencia a la recidiva. El tratamiento se basa en ejercicios isométricos y excéntricos con retorno progresivo a la actividad deportiva. El plasma rico en plaquetas (PRP) se utiliza con el objetivo de acelerar los tiempos de rehabilitación y mejorar el tejido de reparación. El objetivo de este trabajo es presentar los resultados de nuestra serie de pacientes con TR tratados con una o dos infiltraciones de PRP. Evaluación retrospectiva de pacientes tratados entre el año 2012 y 2017. Se analizaron las características del PRP, concentración y cantidad de plaquetas y cantidad de glóbulos blancos (GB) en relación a la concentración plasmática; el tiempo entre el comienzo de los síntomas y la infiltración; el retorno y nivel de retorno al deporte, y tiempo libre de dolor. Se registraron las complicaciones y grado de satisfacción. Veinticuatro pacientes, con una edad promedio de 32 años (DS 9.3 años), un promedio de seguimiento de 41,2 meses (DS 24). Tiempo promedio entre comienzo de los síntomas y la infiltración de 10 meses (DS 8.6). El promedio de concentración de plaquetas en relación con la concentración basal fue 335% (DS 132). Retornaron al deporte el 83%, 75% a menor nivel que previo al comienzo de los síntomas. Al momento del último seguimiento, 45% presentaban dolor nuevamente, con un promedio de tiempo libre de dolor de 21 meses (DS 20). El 80% de los pacientes con tendinopatía rotuliana tratados con PRP lograron retomar la actividad deportiva, aunque 75% de los mismos lo hizo a menor nivel que el previo a la aparición de los síntomas. Si bien el 45% continúan con dolor al momento del seguimiento, un 80% volvería a infiltrarse. Podría haber mayor ventaja infiltrando PRP dentro de los 4 meses de comenzados los síntomas

Background: Patellar tendinopathy (PT) is a very frequent pathology in the sports population. It has multifactorial origin with a degenerative process that´s occurs on the patellar tendon. Its management is usually very difficult and recurrences are frequent. Its treatment is based on isometric and eccentric exercises with progressive return to sports activity. Platelet-rich plasma (PRP) is used to accelerate rehabilitation times and improve repair tissue. The purpose of this paper is to analyze the results of a series of patients with PT treated with one or two infiltrations of PRP. A retrospective evaluation of patients treated between 2012 and 2017 was performed. The characteristics of PRP, concentration and amount of platelets and White Blood Cells count in relation to plasma concentration were analyzed; Also the time between the onset of symptoms and infiltration; the return and level of return to sport, and pain-free time were analyzed. Complications and degree of satisfaction were recorded. Twenty-four patients, with an average age of 32 years (SD 9.3 years), a mean follow-up of 41.2 months (DS 24). Average time between onset of symptoms and infiltration of 10 months (DS 8.6). The average platelet concentration in relation to the baseline concentration was 335% (DS 132). 83%, returned to sport. With 75% at a lower level than before the onset of symptoms. At the time of the last follow-up, 45% had pain again, with an average pain-free time of 21 months (DS 20). 80% of patients with patellar tendinopathy treated with PRP managed to retake the sport activity, although 75% of them did it at a lower level than before the onset of symptoms. Although 45% continue with pain at the time of follow-up, 80% would re-infiltrate. There could be a greater advantage in infiltrating PRP within 4 months of the onset of symptoms

Terapia de ondas de choque en patología músculo-esquelética / Pathology shock wave therapy muscle-skeletal

Extracorporeal shock waves are unique sound waves that generate a rapid increase in pressure in the tissues in which they are applied. They were first used on the management of urolithiasis and later spread to other pathologies such as musculoskeletal. A series of studies have been carried out to support the usefulness of shock waves in patients with plantar fasciitis, Achilles tendinopathy, epicondylitis, rotator cuff injury with or without calcification, patellar tendinopathy and peritrochanteric pathology that has lasted more than three months and have not responded to the initial handling. There is no consensus regarding the specific protocols to be used. In these conditions, shock waves are only a part of a comprehensive treatment, and should always be associated with other conventional therapies. (AU)

Calcific tendonitis and reflex sympathetic dystrophy in a patient with bilateral frozen shoulder syndrome

Calcific tendonitis is a common painful syndrome of the shoulder region that affects mainly women of 40 to 60 years of age. It usually remains asympatomatic at the early stages and in some patients, but produces severe and sometimes protracted pain during the resolution phase. Complex regional pain syndrome [CRPS] and the "frozen shoulder" syndrome are the main entities that need to be considered in the differential diagnosis of the syndrome. Although there are specific criteria to diagnose any of these painful syndromes but occasionally some of these may co-exist and make diagnosis and appropriate treatment quite a challenging task. We present a case with bilateral calcific tendonitis of the shoulders, complicated with causalgia and reflex sympathetic dystrophy [RSD] syndrome that make the two arms of the CRPS. After failure of the conservative treatment [e.g., non-steroidal anti-inflammatory medications, opioids, physiotherapy, intra-articular steroids] to treat both pain and causalgia, we applied repetitive trials of electroacupuncture together with auricular acupuncture and one trial of intravenous regional anesthesia. The patient gradually responded to treatment and regained normal, painless mobility of the shoulders. She returned to normal life activities after five years of debilitating pain in both of her shoulders. We believe that electroacupuncture deserves further clinical research in painful musculoskeletal disorders like calcific tendonitis

Histomorphometric analysis of the Achilles tendon of Wistar rats treated with laser therapy and eccentric exercise / Análise histomorfométrica do tendão calcanear comum de ratos Wistar tratado com laserterapia e exercício excêntrico

Low-level laser therapy is recommended for the treatment of tendinopathies despite the contradictory results related to the ideal dose of energy, wavelength and time of application. This study aimed to assess the effects of laser therapy and eccentric exercise on tendinopathy of the Achilles tendon of Wistar rats. Forty-eight adult male rats were randomly distributed into four groups (L= laser; E= eccentric exercise; LE = laser and eccentric exercise; and R= rest). Laser therapy (904nm/3J/cm2) and/or eccentric exercise (downhill walking; 15o incline treadmill; 12m/min; 50min/day) was started 24h after induction of unilateral tendinopathy and remained for 20 days. At 3, 7, 14 and 21 days after lesion induction, three rats from each group were euthanized and the tendons were collected for histological and morphometric analyses. There was no difference among groups or among times for the characteristics hemorrhage (p=0.4154), fibrinous adhesion formation (p=0.0712), and organization of collagen fibers (p=0.2583) and of the connective tissue (p=0.1046). For these groups, regardless of the time, eccentric exercise led to epitenon thickening (p=0.0204), which was lower in the group treated with laser therapy. Histological analysis revealed differences (p=0.0032) in the number of inflammatory cells over time. They were more numerous in the group that only exercised. This result was confirmed by morphometric analysis, which showed a significant interaction (groups x time) for this characteristic. Eccentric exercise increased (p=0.0014) the inflammatory infiltrate over time (3 and 21 days). However, association with laser therapy reduced inflammatory reaction. On the other hand, the combination of the treatments increased angiogenesis in morphometric (p=0.0000) and histological (p=0.0006) analyses compared with the other groups, while the isolated application of low-level laser reduced this characteristic over time. Animals maintained at rest presented the lowest amount (p=0.0000) of fibroblasts, according to the morphometric analysis. However, histological evaluation showed a significant group x time interaction (p=0.0024). Greater amounts of fibroblasts were observed in groups E, L and LE on the 7th, 14th and 21st days, respectively. The animals that received laser therapy and were exercised showed a greater (p=0.0000) amount of collagen fibers over time. Laser therapy at a dose of 3J and at a wavelength of 904nm, starting 24h after surgical induction of tendinopathy in Wistar rats, is suitable for angiogenesis and prevention of tendon thickening, which can be associated with the intensity of inflammatory process. When associated with eccentric exercise, the therapy has the advantage of increasing the amount of collagen fibers, reducing fibrinous adhesions and inflammatory infiltrate, despite prolonging angiogenesis. Therefore, eccentric exercise performed concomitantly with laser therapy improves the histological properties of the injured tendon.(AU)

O laser de baixa potência é recomendado para o tratamento das tendinopatias apesar dos resultados contraditórios no que se refere a dose de energia ideal, comprimento de onda e tempo de aplicação. O objetivo desse estudo foi avaliar os efeitos da laserterapia e do exercício excêntrico na tendinopatia do tendão calcanear comum de ratos Wistar. Foram utilizados 48 ratos machos adultos. Os animais foram distribuídos aleatoriamente em quatro grupos (L=laser; E=exercício excêntrico; LE=laser e exercício excêntrico, e R=repouso). Após 24h da indução de tendinopatia unilateral, foi iniciada laserterapia (904nm/3J/cm2) e/ou exercício excêntrico (caminhada em declive; esteira com 15o de inclinação; 12m/min; 50min/dia) que permaneceu por 20 dias. Aos 3, 7, 14 e 21 dias após indução da lesão, três ratos de cada grupo foram submetidos à eutanásia, e os tendões foram obtidos para análises histológica e morfométrica. Não houve diferença entre grupos nem entre tempos nas características hemorragia (p=0,4154), formação de aderência fibrinosa (p=0,0712) e organização das fibras colágenas (p=0,2583) e do tecido conjuntivo (p=0,1046). Considerando os grupos, independentemente do tempo, foi observado que o exercício excêntrico ocasionou espessamento do epitendão (p=0,0204), que foi menor no grupo submetido à laserterapia. A análise histológica revelou diferença (p=0,0032) na quantidade de células inflamatórias ao longo do tempo, sendo observado em maior quantidade no grupo apenas exercitado. Esse resultado foi confirmado pela análise morfométrica, que demonstrou haver interação significativa (grupos x tempo) nessa característica, na qual o exercício excêntrico aumentou (p=0,0014) o infiltrado inflamatório ao longo do tempo (3 e 21 dias), porém, quando associado à laserterapia, ocorreu redução da reação inflamatória. Por outro lado, a associação dos tratamentos ocasionou maior angiogênese observada nas análises morfométrica (p=0,0000) e histológica (p=0,0006), quando comparada com os demais grupos, enquanto a aplicação isolada do laser de baixa potência reduziu essa característica ao longo do tempo. Os animais mantidos em repouso foram os que apresentaram menor (p=0,0000) quantidade de fibroblastos, na análise morfométrica, porém na avaliação histológica foi observada interação significativa entre grupo e tempo (p=0,0024). Maior quantidade de fibroblastos foi observada nos grupos E, L e LE, no 7o, 14o e 21o dias, respectivamente. Os animais que receberam laserterapia e foram exercitados apresentaram maior (p=0,0000) quantidade de fibras colágenas ao longo do tempo. A laserterapia na dose de 3J e comprimento de onda de 904nm, iniciada 24h após indução cirúrgica de tendinopatia em ratos Wistar é adequada para angiogênese e para evitar o espessamento do tendão, que pode estar relacionado com a intensidade do processo inflamatório. Quando associada ao exercício excêntrico, a terapia apresenta a vantagem de aumentar a quantidade de fibras colágenas, reduzir a aderência fibrinosa e infiltrado inflamatório, apesar de prolongar a angiogênese. Portanto, o exercício excêntrico realizado concomitantemente com a laserterapia melhora as propriedades histológicas do tendão lesionado.(AU)

Avaliação da migração das células progenitoras após terapia da tendinite equina / Migration evaluation of progenitor cells after treatment of equine tendinitis

A terapia celular vem sendo utilizada com resultados promissores no tratamento da tendinite equina, entretanto ainda existem dúvidas quanto à persistência e ao comportamento dessas células quando implantadas no local da lesão, e quanto à sua migração para outros focos inflamatórios. O objetivo deste estudo foi avaliar a marcação das células-tronco mesenquimais (CTMs) com nanocristal antes e após o implante em lesões tendíneas experimentais do tendão flexor digital superficial (TFDS) de equinos, bem como observar a possibilidade de migração das CTMs marcadas para outro foco de lesão, o membro contralateral do mesmo animal. Para isso, foi realizada a indução de lesão experimental no TFDS em ambos os membros torácicos de cinco equinos e, após sete dias, foram implantadas as CTMs autólogas marcadas com o nanocristal Qtracker 655 em um dos membros dos animais. Após sete dias do implante, foi realizada a biópsia tendínea para posterior avaliação histopatológica, utilizando-se microscopia com fluorescência. Também foi realizado o teste de viabilidade celular antes e após a incubação com o nanocristal. As CTMs marcadas e injetadas no tecido tendíneo mantiveram sua fluorescência sete dias após seu implante, e não ocorreu migração para o membro contralateral. O uso do nanocristal para a marcação das CTMs derivadas da medula óssea equina mostrou-se efetivo pelo fato de essa nanopartícula não ter alterado a viabilidade celular e por ela ter permanecido ativa durante o período implantado...

Cell therapy has been used with promising results in the treatment of equine tendinitis. However, there are still doubts about the persistence and behavior of these cells implanted in the injured tissue and their migration to other inflamed sites. The aim of this study was to evaluate the labeling of mesenchymal stem cells (MSCs) with nanocrystals before and after implantation in experimental tendinitis of the superficial digital flexor tendon (SDFT) of horses, observing the migration possibility of MSCs marked to another lesion, performed on the contralateral limb of the same animal. An experimental lesion was induced in SDFT in both forelimbs of five horses, and after seven days autologous MSCs labeled with Qtracker(r) 655 were implanted in one member of the animals. Tendon biopsy was performed for subsequent histopathological evaluation using fluorescence microscopy seven days after the implant. Cell viability test was also performed before and after incubation with the cell labeling kit. MSCs labeled and injected into the tendon tissue maintained their fluorescence seven days after their implantation and there was no migration to the contralateral limb. The use of nanocrystals for labeling MSCs was effective because it does not alter cell viability and remains active during the experimental period...

Lesiones tendinosas en medicina del deporte: ciencias básicas aplicadas al tratamiento actual / Tendinopathy in sports medicine: the basic sciences and current management

Las lesiones del tendón, denominadas “Tendinosis” son muy frecuentes en la práctica de deportistas de alto rendimiento y recreacionales. Están dentro de las patologías de sobreuso que representan cerca del 60 por ciento de las lesiones deportivas y se relacionan con una sobrecarga cíclica repetidas. Los tendones más afectados del organismo son el rotuliano, aquiliano y manguito rotador. Estudios demuestran que la condición de tendinosis aumenta significativamente su incidencia en relación a la edad; sexo masculino y obesidad. El incremento de la vascularización y terminaciones nerviosas, asociado a un aumento en la producción local de neurotransmisores explicaría la presencia de dolor crónico en las tendinosis. Tendinosis implica una pérdida progresiva de la capacidad de respuesta del tendón para una adecuada regeneración o cicatrización cuando es sometido a una carga cíclica de gran volumen en forma reiterada. La carga cíclica alta repetida induce 1- Estrés oxidativo y apoptosis. 2- Genes cartílago sustituto. Histológicamente esta falla en la respuesta reparativa se refleja en descontrolada proliferación de Tenocitos, disrupción de fibras colágenas, alteraciones en la matriz extracelular, incremento en el fenómeno de apoptosis y cambios en la homeostasis de las Metalo-proteinasas. Se inicia la destrucción de la matriz, aumenta la vascularización y terminaciones nerviosas y el tendón presenta dolor y mecánicamente respuestas a la carga inferiores a un tendón sano. Existe una gran cantidad de opciones de tratamientos pero el objetivo de este artículo es presentar aquellas opciones que nuestro equipo de trabajo aplica, basada en las ciencias básicas y últimos hallazgos con evidencia científica 1- Ejercicios excéntricos asociados a aplicación de ondas de choque radiales han demostrado alto grado de éxito 2- Uso de sustancias esclerosante (polidocanol) y concentrado...

Tendinopathies account for a substantial proportion of overuse injuries associated with sports1 and are a common cause of disability. Most major tendons, such as the Achilles, patellar, rotator cuff, and forearm extensor tendons (among others), are vulnerable to overuse, which induces pathological changes in the tendon. Tendinopathy has an increased incidence with age and the male gender and with obesity. Excessive long-distance running, intensity, and hill work are risk factors for acute. Tendinopathy is a failed healing response of the tendon. The aim of this review is to identify recent advances in the understanding of tendinopathy, particularly from a cell and molecular biology perspective. There has been much new information and there are many gaps in our understanding of the pathogenesis of tendinopathy. The current hypothesisis that tendinopathy is induced when tendon cells experience a large volume of repetitive load. High doses of cyclical strain induce genes for two major pathways ) oxidative stress- apoptosis; and cartilage like genes. The tendon cells become rounded and apoptotic and produce a matrix that contains less Type I collagen and is more cartilaginous and ‘immature’’ in nature. The therapeutic options with clinical evidence are 1- Combining eccentric training and shock wave therapy produces higher success rates compared with eccentric loading alone or shock wave therapy alone. 2- The use of injectable substances such as platelet-richplasma, autologuos blood, polidocanol, corticosteroids, and aprotinin in and around tendons is popular, but there isminimal clinical evidence to support their use: 3- The aim of operative treatment is to excise fibrotic adhesions, remove areas of failed healing, and make multiple longitudinal incisions in the tendon to detect intratendinous lesions and to restore vascularity and possibly stimulate the remaining viable cells to initiate cell matrix response...

El objetivo de este trabajo es describir los resultados obtenidos durante la aplicación combinada de ondas de choque radiales más entrenamiento excéntrico en pacientes con tendinopatia rotuliana crónica de más de cuatro meses de evolución y que habían realizado por lo menos dos tratamientos conservadores con pobres o nulos resultados. A 4 meses de seguimiento, el VISA score se incrementó de 53,8 a 81,6 demostrando mejoras en la función y la actividad, así como la disminución del dolor. Veintitrés de los 30 (76 por ciento) pacientes refirieron excelentes y buenos resultados según la Roles and Maudsley Scale. Los resultados obtenidos con la combinación de ambos tratamientos demostraron ser una alternativa para el tratamiento conservador de la patología rotuliana crónica

Resultados de la terapia por onda de choque focal en calcificaciones del manguito rotador / Results of focal shock-wave therapy for calcifying tendinitis of the rotator cuff

Introducción: El objetivo del presente trabajo es evaluar, en forma prospectiva, los resultados del tratamiento mediante la aplicación de ondas de choque focales, en un grupo de pacientes con calcificaciones sintomáticas del manguito rotador. Materiales y métodos: Se incluyeron 44 casos consecutivos de calcificaciones localizadas en alguno de los tendones del manguito rotador, en 43 pacientes con cirugías fallidas o tratamiento previo, al menos, por 6 meses, con síntomas persistentes. Resultados: En la evaluación al año, la calcificación había desaparecido completamente en 20 pacientes (45,5 por ciento). En 13 casos (29,5 por ciento), hubo un cambio significativo en el tamaño o la densidad. En 11 casos (25 por ciento), no hubo modificaciones. El dolor, según la escala analógica visual descendió de un promedio de 5,5 a 1,4 (p <0,0001). El puntaje de UCLA pasó de un valor inicial promedio de 15,7 a un valor de 29,3 (p <0,0001). El puntaje de Autoevaluación ASES fue de 84,6 comparado con un valor inicial de 48 (p <0,0001). El 77 por ciento de los pacientes estuvieron satisfechos con el procedimiento. Conclusión: El estudio sugiere que la terapia por onda de choque es una alternativa válida para pacientes que no han respondido al tratamiento conservador ni al quirúrgico

Análise da eficácia do laser de baixa potência no tratamento da dor tendínea em ratos imunossuprimidos / Analysis of low-level laser therapy efficacy on tendon pain treatment in immunosuppressed rats

O comprometimento do sistema imune, que pode ser apresentado por indivíduos com doenças crônicas, leva à baixa resposta imunológica. Um dos tratamentos utilizados para lesões agudas em tendões é o laser de baixa potência, contudo há uma lacuna em relação ao seu uso em imunodepressão. O objetivo do presente estudo foi analisar se o laser de baixa potência é eficaz para o tratamento da dor em ratos imunodeprimidos submetidos a trauma tendíneo. Foram utilizados 23 ratos, machos, da linhagem Wistar, divididos aleatoriamente em três grupos: grupo controle, placebo e laser. Os animais foram imunodeprimidos (por administração de Ciclosporina A) e submetidos à lesão no tendão calcâneo direito, com impacto de cerca de 0,40 J. Para o tratamento, utilizou-se laser de baixa potência, 670 nm, 30 mW e dose de 2 J/cm2, durante 3 dias. A avaliação da dor foi realizada pelo teste de incapacidade funcional e por filamento de Von Frey digital. Os resultados apresentaram valores significativos para o grupo laser, com diminuição de dor funcional e da dor à pressão na superfície plantar e no local lesionado (tendão calcâneo direito). Portanto, concluiu-se que o laser de baixa potência é eficaz para reduzir a dor em ratos imunodeprimidos submetidos a trauma tendíneo.

The commitment of immune system, which may be presented by individuals with chronic diseases, leading to a low immune response. One of the treatments used for acute injuries in tendons is the low-power laser, however there is a gap in relation to its use in immunosuppression. The objective of this study was to analyze if low-level laser therapy is effective for the treatment of pain in immunosuppressed rats subjected to trauma tendon. We used 23 male rats of Wistar strain, divided randomly in three groups: control group, placebo and laser. The animals were immunosuppressed (by administration of Cyclosporin A) and underwent right Achilles tendon injury, with impact of about 0.40 J. For treatment, we used low-level laser, 670 nm, 30 mW and 2 J/cm2, during 3 days. Pain assessment was performed by the functional incapacitation test and von Frey filament digital. The results showed a reduction of functional pain and pressure pain on the plantar surface and the injured site (right Achilles tendon) for the laser group. Therefore, we concluded that the low-power laser is effective for reducing pain in immunosuppressed rats subjected to trauma tendon.

Estudo morfométrico da terapia LED de baixa potência em tendinite de ratos / Morphometric study of low power LED therapy tendonitis in rats

A terapia LED de baixa potência possui efeitos analgésico e antiinflamatório. O objetivo desse estudo foi analisar a ação da terapia com LED de baixa potência na reparação tendínea por meio de histologia e histomorfometria. Foram usados 25 ratos Wistar, de 220 a 250 g, divididos em três grupos experimentais avaliados no 7º e 14º dia: A, tendinite induzida sem tratamento; B, tendinite induzida tratada com LED de baixa potência, densidade de energia 4 J/cm² por 120 segundos; e C, sem indução de tendinite. A histomorfometria mostrou-se altamente significativa (p<0,001) na terapia com LED em contrarrelógio de 14 dias, comparada ao grupo saudável (C). Entretanto, não mostrou significância levando em conta o grupo tendinite (A14), em que valor p>0,05. As análises histológica e histomorfométrica demonstraram qualitativo e quantitativo aumento no número de fibroblastos aos sete dias de tratamento, e das fibras colágenas, aos 14 dias, para grupo tratado com LED de baixa potência em relação ao grupo sadio (C). O mesmo não foi percebido quando relacionado ao grupo tendinite (A14).

The low power LED therapy has analgesic and anti-inflammatory effects. The objective of this study was to analyze the action of therapy with low power LED on the tendon repair, using histology and histomorphometry. Were used 25 Wistar rats, with 220 to 250 g, divided into three experimental groups (7 and 14 days): A7 and A14 induced tendonitis without treatment; B7 and B14, induced tendinitis treated with LED low power density energy 4 J /cm² for 120 seconds; and C, without induction of tendinitis. Histomorphometry was highly significant (p<0.001) with LED therapy against the clock for 14 days, compared with the healthy group (C). But not significant compared with the tendinitis group (A14) (p> 0.05). Histology and histomorphometry analysis demonstrated qualitative and quantitative increase in the number of fibroblasts to seven days of treatment, and collagen fibers at 14 days for the group treated with LED low power compared to the healthy group (C). But it is unclear even when related to the tendinitis group (A14).

Ação anti-inflamatória da fração lipídica do Ovis aries associado ao ultrassom terapêutico em modelo experimental de tendinite em ratos (Rattus norvegicus) / Anti-inflammatory action of the Ovis aries lipidic fraction associated to therapeutic ultrasound in an experimental model of tendinitis in rats (Rattus norvegicus)

CONTEXTUALIZAÇÃO: Estudos demonstram o efeito benéfico da aplicação tópica de ácidos graxos como agentes cicatrizantes. A fração lipídica do Ovis aries apresenta uma ação anti-inflamatória que acelera o processo de cicatrização. O ultrassom aumenta o fluxo sanguíneo bem como a extensibilidade das estruturas de colágeno e tendões. OBJETIVOS: Analisar a ação anti-inflamatória da fração lipídica do Ovis aries associado ao ultrassom terapêutico (UST) pulsado e à fricção em modelo de tendinite induzida. MÉTODOS: Cinquenta ratos Wistar foram distribuídos nos seguintes grupos: controle, gel Ovis aries - uso tópico - UST pulsátil + loção estéril (oil free), UST pulsátil + gel Ovis aries, loção estéril (oil free) - uso tópico. Para induzir a tendinite, utilizou-se uma injeção intratendínea de 10µL de colagenase no tendão do calcâneo direito. O tratamento consistiu em aplicações diárias de ultrassom, com os seguintes parâmetros: modo pulsado 10 por cento, frequência de 1 MHz, pulsátil a 10 por cento com intensidade de 0,5W/cm², durante sete ou 14 dias. RESULTADOS: A variação do número de células inflamatórias, para os animais tratados por 14 dias, com relação aos grupos controle, UST + oil free e UST + Ovis aries, apresentou resultados significativos p<0,001. O grupo Ovis aries + massagem e o grupo massagem + oil free apresentaram resultados significativos, p<0,01. Nos animais tratados por sete dias, observou-se que o grupo UST + Ovis aries, em relação ao controle, é estatisticamente significativo, p<0,05 CONCLUSÃO: Pode-se concluir que o tratamento com UST + Ovis aries é mais efetivo que os outros tratamentos, visto que consegue reduzir o número de células inflamatórias no tempo de sete e 14 dias.

BACKGROUND: Studies have demonstrated the beneficial effects of topical application of fatty acids as healing agents. The lipid fraction of Ovis aries have an anti-inflammatory action that accelerates the healing process. Ultrasound increases blood flow and the extensibility of collagen structures and tendons. OBJECTIVES: To assess the anti-inflammatory action of the Ovis aries lipid fraction associated to pulsed therapeutic ultrasound and friction in an induced tendinitis model. METHODS: Fifty Wistar rats were divided into four groups: control that consisted of Ovis aries gel for topical use; pulsed ultrasound plus oil free sterile lotion; pulsed ultrasound plus Ovis aries gel; and oil free sterile lotion for topical use alone. To induce tendinitis a 10µL intratendinous injection of collagenase was injected into the right Achilles tendon of rats. Treatment consisted of daily applications of ultrasound using the following parameters: 10 percent pulsed mode, 10 percent pulsed frequency of 1 MHz and intensity of 0.5 W/cm² for seven or fourteen days. RESULTS: After 7 days of treatment, only the Ovis aries plus ultrasound group showed statistically significant difference when compared to the control group.The variation in the number of inflammatory cells on animals treated for fourteen days for the control, ultrasound plus oil free, ultrasound plus Ovis aries, Ovis aries plus massage and massage plus oil free groups were statistically significant different, p<0.01. It was observed in animals treated for seven days that the ultrasound plus Ovis aries group was statistically significant better than the control group, p<0.05. CONCLUSION: It can be concluded that treatment using ultrasound plus Ovis aries is more effective than other treatments as it produces significantly better reduction on the number of inflammatory cells at 7 and 14 days.
