Introduction: Les tendinopathies sont des pathologies d’hyper-utilisation très fréquentes, tant chez des sujets sportifs ou non-sportifs. Leur incidence est actuellement en augmentation. La tendinopathie patellaire proximale est une des tendinopathies les plus réfractaires au traitement conservateur et peut affecter la qualité de vie en limitant les activités sportives qu'elles soient récréationnelles ou professionnelles. Objectifs : L’objectif de cette étude est d’évaluer les effets à long terme du PRP pour traiter les tendinopathies patellaires proximales et éventuellement d’en identifier des facteurs de bon pronostic. Matériel et méthodes: 25 tendinopathies patellaires proximales ont été traités par PRP et ont été suivie à plus d’un an (dont 9 sujets sont suivi jusque 48 mois post-infiltration). Les patients sont évalués selon les questionnaires VISA-P, IKDC et un questionnaire reprenant leurs habitudes. Les scores VISA-P et IKDC sont croisés avec le troisième questionnaire afin d’obtenir des moyennes en rapport avec les réponses de ce dernier. Résultats : Aucun patient n’a été traité par chirurgie après l’infiltration. L’évolution des patients a tendance à être toujours positive jusqu’à 48 mois. Les facteurs semblant être bénéfiques sur l’évolution des patients sont : l’activité sportive à une fréquence de six à huit heures de sport par semaine, la réalisation d’exercices excentriques à domicile, une hydratation de plus d’un litre et demi par jour, un échauffement de plus de dix minutes ainsi que l’âge des patients (<30 ans). Conclusion : Le traitement d’une tendinopathie patellaire proximale par infiltration de PRP est efficace à long terme (jusque 4 ans). La réalisation d’exercices excentriques réguliers semble nécessaire et permet d’observer la poursuite de l’amélioration clinique des patients. [less ▲]

Intoduction : De nos jours, la majorité des patients consultent un dentiste pour des problèmes dentaires stricto senso et fort peu pour des pathologies liées au parodonte. Ce dernier est pourtant leur structure d’ancrage permettant le maintien des dents et donc de l’appareil manducateur. La présence d’un saignement gingival au brossage quotidien, étant la plupart du temps non douloureux, ne déclenche souvent aucune inquiétude ni demande de consultation. Il s'agit pourtant d'un des signes cliniques les plus évidents des parodontopathies qui affectent, à des degrés divers, pratiquement 90% de la population en France dans toutes les tranches d'âge et cause la perte de 30 à 40% des dents. Objectif : Le parodonte représente un des points fragiles de notre corps permettant facilement l’entrée de bactéries dans la circulation sanguine et expliquant une relation entre la maladie parodontale et certaines maladies systémiques. Qu’en est-t-il des tendinopathies? Cette étude a pour objectif de mettre en évidence les relations entre l’hygiène bucco-dentaire et ses répercussions sur les tendinopathies. Matériel & méthode : Soixante-quatre sportifs réguliers ont participé à un examen parodontal complet au cours duquel les paramètres cliniques suivants ont été enregistrés: indices de plaque (PI), indice gingival (GI) et indice de saignement papillaire (PBI). Les athlètes ont été répartis en trois groupes en fonction de leur état de santé : « athlètes non blessés » (ANB), « athlètes blessés » (AB) et « athlètes régulièrement blessés » (ARB). Résultats : En comparant les groupes ANB et AB on remarque une différence significative entre les trois valeurs enregistrées (IP : p=0.023 ; IG : p<0.0001 ; PBI : p<0.0001). Le groupe ARB ne montre pas de différences significatives avec les deux autre groupes. Discussion et Conclusion : Notre étude montre une relation entre les parodontopathies et les tendinopathies mais le modèle ne permet pas à déterminer l’origine ni l’importance de cette relation. Il est recommandé aux athlètes de prêter suffisaient attention à leur hygiène de vie générale et de ne pas négliger leur hygiène dentaire. [less ▲]

Introduction Every physical activity is tiresome for the body; muscles produce metabolites and lactic acid which limit its working ability. It is then necessary to efficiently and quickly recover after the effort. In fact, a bad recovery could bring prejudice to the following performance and the athlete's physical state. Active recovery and balneotherapy together with new techniques such as cryotherapy and electro stimulation are upcoming tools to recover better. The goal of this study was to compare the impact of 2 types of electro stimulator : « VeinoPlus Sport » (VPS) and « TENS » on amateur soccer players after Yo-Yo-type effort. Material and methods In an identical context, each athlete (20 soccer players; average age 17,1 ± 0,79) benefited from VPS and TENS during 2 different treatment sessions after 2 Yo-Yo-type efforts. Four blood samples were taken (lactate, blood gases, ions, cardiac markers,...) and an explosiveness Myotest evaluation was conducted respectively before effort, just after effort, after recovery, and after the second effort. A questionnaire on the fatigue state was filled out by each athlete. For the statistical analysis, we used the Anova algorithm of the StatPlus system and a Scheffé test. Results All athletes have ran a greater distance in their second effort especially in the VPS group but differences were insignificant. The test lead to a significant variation of lactate, HCO3- ions and myoglobin. The study of other blood parameters and of the explosiveness parameters didn't show any significant variations. Nevertheless according to the subjective athlete's opinion the VPS group has noted less legs pain, less overall fatigue, less diminishment of strength and fitter than the TENS group between 12 and 24 hours after effort. Finally all athletes have said to like the use of a electro-stimulation recovery device better than their normal daily recovery techniques without expressing any preferences between VPS and TENS. Discussion - Conclusion This comparative study only shows minor differences, non significant, between the two devices. The two groups have ran the greatest distance during the second effort which suggests that the test wasn't tiresome despite biological signs of "fatigue". However on subjective criteria of recovery and well-being a slight preference was shown for the VPS device. The results should be taken into consideration in a other comparative study of the recovery devices with more tiresome effort. [less ▲]

Les thérapeutiques «passives» classiques (anti-inflammatoires, infiltrations de corticoïdes…) des tendinopathies, utilisées de manière relativement empirique, réduisent la douleur et l’inflammation, sans modifier fondamentalement la structure du tendon, expliquant leur vocable et caractère «passif». La rééducation excentrique a été appliquée aux tendinopathies chroniques, non seulement de par l’échec des traitements classiques, mais aussi en raison d’une meilleure compréhension physiopathologique des tendinopathies. Diverses études soulignent l’efficacité de la rééducation excentrique qui, après 20-30 séances, entraîne la guérison et surtout prévient le risque de chronicité. Les ondes de choc, modifiant la structure tendineuse, permettraient une guérison à plus long terme. [less ▲]

Objectives: The restorative properties of platelets, through the local release of growth factors, are used in various medical areas. This article reviews fundamental and clinical research relating to platelet-rich plasma applied to tendinous lesions. Materials and method: Articles in French and English, published between 1 January 2012 and 30 September 2014 dealing with PRP and tendons were searched for using the Medline and Scopus data bases. Results: Forty-seven articles were identified which addressed pre-clinical and clinical studies: 27 relating to in vitro and in vivo animal studies and 20 relating to human studies. Of these, 5 addressed lateral epicondylitis, 2 addressed rotator cuff tendinopathies, 10 dealt with patellar tendinopathies and 3 looked at Achilles tendinopathies. Conclusions: The majority of pre-clinical studies show that PRP stimulates the tendon's healing process. However, clinical series remain more controversial and level 1, controlled, randomised studies are still needed. [less ▲]

INTRODUCTION: Cardiopathies are the world's leading cause of mortality and morbidity. Although rare, cardiovascular accidents can occur during intense and infrequent sporting activity, particularly among those who are unaware of their heart condition. The development of cardiospecific biochemical markers has led to a reconsideration of the role of biology in the diagnosis of cardiovascular illnesses. The aim of this study therefore was, through the use of cardiac biomarker assays, to highlight the impact of sustained physical effort in the form of intense and prolonged concentric isokinetic exercise and to research potential cardiovascular risks. MATERIALS AND METHODS: Eighteen subjects participated in a maximal concentric isokinetic exercise involving 30 knee flexion-extensions for each leg. Five blood tests were taken to study the kinetics of the cardiac biomarkers. Haemodynamic parameters were measured continuously using a Portapres, and respiratory parameters were measured using a Sensormedics Vmax 29C. RESULTS: The results showed significant increases in the creatine kinase, myoglobin, homocysteine and haemoglobin cardiac markers. Evolutionary trends were also observed for the following biomarkers: NT-proBNP, myeloperoxydase and C-reactive protein. All the physiological parameters measured presented statistically significant changes. CONCLUSION: Isokinetic effort leads to the release of cardiac markers in the blood, but these do not exceed the reference values in healthy subjects. Maximal concentric isokinetic exercise does not, therefore, lead to an increased risk of cardiovascular pathologies. [less ▲]

Infiltration of Platelet-Rich Plasma (PRP) may be considered as a recent therapeutic option for chronic tendinopathies. The aim of this study is to evaluate the clinical status and the return to sports activities in patients with chronic proximal patellar tendinopathies. Twenty subjects with chronic proximal patellar tendinopathy benefited from 1 infiltration of PRP coupled with a standardized eccentric rehabilitation. The follow-up (up to 1 year) was assessed by means of a Visual Anologue Scale (VAS), the International Knee Documentation Committee (IKDC) form and the Victorian Institute of Sport Assessment (VISA-P) score. Moreover, subjects had to answer an information questionnaire concerning their life and sports activities. Seventy percents of the patients reported a favourable evolution with decrease of pain, and returned to sports activities. With time, VAS dropped significantly and both IKDC and VISA-P scores improved also significantly. This study confirms that a local injection of PRP coupled with a program of eccentric rehabilitation for treating a chronic jumper’s knee, improves pain symptoms and the functionaliti [less ▲]

The anterior tarsal tunnel syndrome is a rare entrapment neuropathy of the deep peroneal nerve beneath the inferior extensor retinaculum of the ankle. It is unrecognized and may lead to misdiagnosis and delayed treatment. We report the case of a 77 years old patient complaining of anterior tarsal tunnel syndrome’s symptoms with neuropathic pain located at the dorsal part of the foot without any sensorimotor loss. The electroneuromyography was in favour of the motor impairment of the deep peroneal nerve. MRI exploration of the ankle showed a millimetric bony overgrowth of the upper pole of the navicular irritative to the deep peroneal nerve. Infiltration at overgrowth of the navicular provided a partial and temporary decrease in pain symptoms. Surgical nerve decompression was then considered. [less ▲]

Introduction: Some clinical series have evaluated the effect of platelet-rich plasma (PRP) in the treatment of jumper’s knee. Although it is possible that a single infiltrative administration may prove to be an effective treatment for this indication, most of the existing studies evaluated the effects of 2 or 3 successive infiltrations. The aim of this study was to evaluate whether 2 infiltrations of PRP proves moreeffective than a single treatment. Methods: Twenty patients suffering from chronic jumper’s knee were enrolled into our prospective, randomized and comparative study of level 2, and split into two randomized groups (1 or 2 infiltrations of PRP, respectively). The 3-month follow-up evaluation consisted of VAS, IKDC and VISA-P scores, along with algometer, isokinetic and ultrasounds evaluations. After 1 year, subjects were contacted to define their functional evolution. Results: The concentration of the PRP used for each infiltration was similar in both groups, and contained no red or white cells. Results revealed no difference in treatment efficacy between the groups.Discussion: The comparison between 1 or 2 infiltrations of PRP did not reveal any difference between the 2 groups at short to mid term. A second closely-timed infiltration of PRP to treat jumper’s knees is not necessary to improve the efficacy of this treatment in the short term.

Introduction: Gal-3 is a carbohydrate binding lectin produced by macrophages, upregulated in hypertrophied heart, emerging as a mediator for fibrosis development and cardiac remodeling. ST2 is a family member of IL-1 receptors initially known for its role in immunological processes. It has a potential role in the cardiac pathogenesis. These receptors are led in cardiomyocytes and fibroblasts due to a mechanical stress. We aimed to examine the evolution of Gal-3 and ST2 in trailers who ran one of the most challenging ultra-marathon in the world: the Tor des Géants (330 km, altitude range: 24000m). Methods: Levels of plasma Gal-3 and ST2 were determined at 4 times: before the start, after 158km, at the end and 3 days after the end of the race in 33 trailers. Samples were directly centrifuged and frozen at -80°C. Gal-3 measurement was performed on the VIDAS (Biomerieux) and ST2 was analyzed with the Presage ST2 Assay (Critical Diagnostic). The reference values are <17.8ng/mL for Gal-3 and <35ng/mL for ST2. Statistica was used for the statistical analysis (ANOVA). We calculated the difference between the different time and expressed in delta: Δ1=(T2-T1)/T1*100, Δ2=(T3-T2)/T2*100, Δ3=(T4-T3)/T3*100, Δ4=(T3-T1)/T1*100, Δ5=(T4-T1)/T1*100. After that, we tried to correlate the delta between them (results= R(p-value)). Results were considered as significant with p<0.05. Results: Plasmatic levels of Gal-3 did never exceed the cut-off of 17.8ng/mL, except for 1 trailer in T2. A slight increase of levels of Gal-3 was observed at T2 (min-max:7.5-17.6ng/mL). These ones did not vary a lot at T3 (min-max:7.0- 18.8ng/mL) but return to normality at T4 (min-max:6.0-12.8ng/mL). For ST2, at T1, 12 subjects had plasmatic levels above the reference value of 35ng/ml. At T2, only 2 trailers blood samples were still in the reference interval. Indeed, a great increase of ST2 plasmatic levels observed (min-max:18.8-158.8ng/mL). A slight decrease of ST2 levels was observed at T3, but only one subject had a value below 30ng/ml (min-max:20.1-182.7ng/mL). However, a subject had still plasmatic levels above T2 values. A return to normality was observed at T4 with 16 trailers blood levels in the reference interval (min-max:12.0-56.4ng/mL). We observed an increase for Gal-3 and ST2, above the reference values only for ST2. We noted for both a decrease up to the normal values 3 days after the trail. For the correlation between deltas, we observed that Gal-3 and ST2 are correlated for each delta. Discussion: A logical correlation is observed between Gal-3 andST2 as they are involved in cardiac fibrosis and inflammation. But we do not known why it is not in the same proportion. We know that some trailers take NSAIDs and painkillers during the race. The results of this study demonstrate that this exercise was associated with biochemical abnormalities that may reflect adverse consequences on cardiac structure as fibrosis. However, ST2 values were higher, perhaps due to a mechanical stress more than a cardiac stress. Gal-3 is perhaps then more cardiospecific than ST2. [less ▲]

BACKGROUND: Besides magnetic resonance imaging, dual energy X-ray absorptiometry (DXA) seems the most reliable tool to evaluate body composition and is often considered as the gold standard in clinical practice. Bioelectrical impedance analysis (BIA) could provide a simpler, portative, and less expensive alternative. Because the body composition assessment by BIA is device-dependent, the aim of this study was to appraise the concordance between the specific bioelectrical impedance device InBody S10 and DXA for the body composition evaluation. METHODS: Body composition, included appendicular lean mass divided by height squared (ALM/ht2) was measured by DXA (Hologic QDR Discovery device) and by BIA (InBody S10 Biospace device). Agreement between tools was assessed by means of the Bland Altman method and reliability was determined using the IntraClass Coefficient (ICC). ICC was also computed to assess the reliability of the test-retest performed by the same operator or by two different ones. RESULTS: A total of 219 subjects were enrolled in this study (mean age: 43.7 +/- 19.1 years old, 51.6% of women). For the ALM/ht2, reliability of the test-retest of the BIA was high with an ICC of 0.89 (95%CI: 0.86-0.92) when performed by the same operator and an ICC of 0.77 (95%CI: 0.72-0.82) when performed by two different operators. Agreement between ALM/ht2 assessed by DXA and BIA was low (ICC = 0.37 (95%CI: 0.25-0.48)). Mean ALM/ht2 was 9.19 +/- 1.39 kg/m2 with BIA and 7.34 +/- 1.34 kg/m2 with DXA, (p < 0001). A formula developed using a multiple regression analysis, and taking into account muscle mass assessed by BIA, as well as sex and body mass index, explains 89% of the ALM/ht2 assessed by DXA. CONCLUSIONS: Although our results show that the measure of ALM/ht2 by BIA is reliable, the agreement between DXA and BIA is low. Indeed, BIA seems to overestimate ALM/ht2 compared to DXA and, consequently, it is important to use an adapted formula to obtain measurement of the appendicular lean mass by BIA close to that measured by DXA.

Teeth are the object of multiple attentions and care but unfortunately, it is not the same case of the periodonte, their point of anchoring and essential support. What could be more commonplace than a bleeding arising during the daily brushing? Being not painful, it activates very often no concern and no request of consultation. It is nevertheless about one of the most obvious clinical signs of the periodontal diseases which affect, to varying degrees, practically 90 % of the population in France in all groups of ages and is responsible of the loss from 30 to 40 % of the teeth. For several decades, the scientific world admits a relation between the periodontal disease and certain systematic diseases, as the endocarditis, the atherosclerosis, the diabetes… And what about tendinopathies? Their appearance is often spontaneous without specific medical origin and their cure turns out long and painful. This review has for objective to highlight the relations between the oral hygiene and sportsmen. [less ▲]
