Aim of the study: Injections of platelet-rich plasma (PRP) constitute a new therapeutic for treating chronic tendinopathies. The injection being carried out in the tendon, the volume of PRP should thus be minimal (to decrease the intra-tendinous pressure and to minimize pain). This PRP should also have a raised platelet count. The quantity of released growth factors could be related to the system of preparation employed. We thus carried out a comparative study of 5 techniques of preparation of PRP described in the literature. Patients and methods: Samples of venous blood were taken among 5 patients in order to compare 5 techniques of preparation of PRP: University Hospital of Liège technique, Curasan® PRP Kit, Plateltex®, GPS® and RegenLab®. Results: The various techniques make it possible to obtain more important platelet concentration than in blood, with variable volumes (0,3 mL to 6 mL). The number of platelets/microlitre appears higher with Plateltex® and obtains smallest volume of PRP. The other techniques also give small volumes excepted for the GPS® II. The number of collected platelets with this technique appears thus higher. The best collect efficiency is obtained with RegenLab®. Conclusion: The technique Plateltex® makes it possible to collect the highest concentration of platelets in the smallest volume available. [less ▲]

We report a rare case of single cervical metas- tasis of breast cancer. Bone metastases are the most frequent in breast cancer. early diagnosis combined with the new the- rapeutic advances have considerably improved the quality of life and increased the survival. imaging plays a great role in the diagnosis, particularly scintigraphy and radiography, but sometimes also ct and Mri. the treatment is currently not standardized and it combines hormone therapy, chemotherapy, radiotherapy, and / or surgery.

Introduction.— La force et l’endurance respiratoires seraient susceptibles d’influencer certaines performances sportives. Outre la spirométrie classique, les pressions inspiratoires et expiratoires maximales ainsi que le reniflement maximal apprécient la force respiratoire. La musculature respiratoire pourrait être améliorée par l’utilisation régulière d’appareils avec résistance inspiratoire ou expiratoire. Méthodes.— Dix-neuf sujets, âgés de 18 à 30 ans, pratiquant un sport de loisir ont bénéficié d’un entraînement de huit semaines sur Powerbreathe® (60 inspirations par jour), la résistance étant fixée à 85 % de la pression inspiratoire maximale déterminée lors d’une évaluation préalable. Résultats.— Une augmentation de 21,77 % de la pression inspiratoire maximale, de 17 % de la pression expiratoire maximale et de 18 % du test de reniflement ont été constatées après huit semaines d’entraînement. Conclusions.— Un entraînement spécifique de la musculature inspiratoire augmente effectivement la puissance de ces muscles (manoeuvres volontaires et non-invasives - Macro 5000® - mesure des pressions respiratoires et du sniff test).

Introduction: The tendon is a tissue which does not heal easily. Recently, several studies have demonstrated the positive effects of platelets on the healing process of tendons. A local injection of platelet–rich plasma (PRP), which releases in situ many growth factors, has the potentiality to enhance the tendon healing process. The aim of our experiment was to ascertain by an original mechanical measure whether the use of PRP was of interest for accelerating the healing process of rats’ Achilles tendons after surgical induced lesion. Methods: A 5mm defect was surgically induced in 90 rats’ Achilles tendon. Rats were divided into 2 groups of 45: (A) control (no treatment) and (B) PRP treatment. Rats of group B received a PRP injection in situ after the surgery. Afterwards, rats of both groups were placed in their cages without immobilization. After 5, 15 and 30 days, 10 traumatized Achilles tendons of each group were dissected and removed. Immediately after sampling, tendons were submitted to a biomechanical tensile test up to rupture, using a “Cryo-jaw”. After that, transcriptomic analyses were made on the tendon samples, to study the expression of type III collagen, matrix metalloproteases and tenomodulin. A hydroxyproline dosage was done to quantify the collagen in the tendon during its healing process. Tendons of the 15 remaining rats of each group were subjected to a histological study, respectively at day 5, 15 and 30 (5 rats for each time). Results: We demonstrated that the force necessary to induce tendon rupture during biomechanical tensile test study was greater for tendons which had been submitted to an injection of PRP compared to the control group: +19% (day 5), +30% (day 15) and +43% (day 30). Histological study showed that PRP could enhance cells proliferation, angiogenesis and collagen organisation. Our biochemical analyses did not explain beneficial effects of PRP. Indeed, there was no significant difference neither between the expression of different studied genes, nor in the quantity of hydroxyproline between both groups. Conclusion: This experimentation has shown that a PRP injection could accelerate the tendons healing process and improve its quality. [less ▲]

Cartilaginous exostosis, a frequent benign bone tumour, develops mainly during the growth. Often asymptomatic, it can be painful, compressive or unsightly, involving a surgical treatment. The diagnostic is based on radiological imaging. At adulthood, pains, a growth of the exostosis volume or characteristic imaging modifications lead to a resection in order to exclude a sarcomatous transformation. We report the case of a patient showing a painful exostosis of the femur distal metaphysis. [less ▲]

J Strength Cond Res 24(x): 000-000, 2009-The purpose of this study was to investigate the ability of the load-velocity relationship to accurately predict a bench press 1 repetition maximum (1RM). Data from 3 different bench press studies (n = 112) that incorporated both 1RM assessment and submaximal load-velocity profiling were analyzed. Individual regression analysis was performed to determine the theoretical load at zero velocity (LD0). Data from each of the 3 studies were analyzed separately and also presented as overall group mean. Thereafter, correlation analysis provided quantification of the relationships between 1RM and LD0. Practically perfect correlations (r = approximately 0.95) were observed in our samples, confirming the ability of the load-velocity profile to accurately predict bench press 1RM. [less ▲]

Introduction: For a few years, the positive effect of platelets on the healing process of different tissues (skin, bones...) was demonstrated. In fact platelets contain lots of growth factors which can be release locally and enhance the healing process. Thus the aim of our experiment was to ascertain by an original mechanical measure whether the use of PRP was of interest for accelerating the healing process of rats’ Achilles tendons after surgical induced lesion. Methods: Ninety rats’ Achilles tendons were sectioned. Forty-two rats beneficed of a PRP injection in situ. After 5, 15 and 30 days, 15 rats of both groups were euthanized after tendon sampling which were immediately submitted to a biomechanical tensile test until tendon rupture, using an original method of measurement (“cryo-jaw”). Histological and biochemical analyses were made as well as a quantification of collagen with an original procedure (quantification of the “greys” on histological cross-sections). Results: Tendons in the PRP group were more resistant to rupture than those in the control group. Histological findings showed in this group an increase of collagen proliferation and better collagen fibres reorganization. However, we did not find any biochemical difference neither in term of encoding gene expression for type III collagen, matrix metalloprotease 9 and tenomodulin. Conclusion: Our animal study demonstrated that an injection of PRP could accelerate the tendons healing process and improve its quality. [less ▲]
