Autologous platelet-rich plasma (PRP) gel is increasingly used in the treatment of a variety of soft and bony tissue defects, such as accelerating bone formation and in the management of chronic non-healing wounds. We performed this study to assess the benefits of using autologous PRP gel in the treatment of acute limb soft tissue wounds. 59 patients with(More)
We present a retrospective study of the epidemiology and the results of treatment of fractures of the proximal femur in 74 patients aged 50 or under. Cervical fractures comprised 17% of the 74 fractures and were equally caused by high and low energy trauma. Trochanteric and subtrochanteric fractures comprised 83% of the total and were mainly caused by(More)
BACKGROUND It is well established that growth factors play a critical role in the healing process of connective tissues. To our knowledge, there are no studies in literature concerning the influence of PRP on growth factors expression. HYPOTHESIS The aim of this study was to assess the effect of a single application of platelet rich plasma (PRP) gel in a(More)
The imaging findings of intra-articular haemangiopericytomas have not been described previously. We report on a 35-year-old man with a primary malignant haemangiopericytoma of the left knee joint. MRI demonstrated joint effusion and a heterogeneous mass with haemorrhagic components and multiple peripheral serpentine signal voids, suggesting the presence of(More)
Ewing's sarcoma arising in the right fibula was diagnosed in a 12 years old female, considering clinical presentation, radiological findings and histological features. Our work points towards a possible neuroectodermal origin of Ewing's sarcoma, since MIC2/12E7 marker was found to be positive. Translocation t (11;22) (q24;q12) was found as the main(More)
OBJECTIVE CD30 antigen has long been considered to be restricted to the tumour cells of Hodgkin's disease and of anaplastic large cell lymphoma as well as to T and B activated lymphocytes. It is now apparent that the range of normal and neoplastic cells, which may express CD30 antigen, is much wider than was at first thought. In order to gain insight into(More)
Originally, expression of the CD30 antigen was shown to be typical of the tumor cells of Hodgkin disease and of anaplastic large cell lymphomas. In reactive lymphoid tissue, CD30 is expressed only in a small population of activated lymphoid blasts. Since then, several reports have been published describing CD30 expression in non lymphoid tissues and(More)
The aim of this laboratory work was to study the compressive and flexural characteristics of various commercially available bone graft substitute (BGS) ceramic cements, in their initial as-mixed condition, and compare them to polymethylmethacrylate (PMMA). The tested biomaterials were two different calcium phosphate cements, two different calcium sulphate(More)
The aim of this study was to explore the intensity of post-arthroscopy knee pain during the first 24 hours, and to study the influence of pre-operative pain, tourniquet time and amount of surgical trauma on post-arthroscopy pain. In 78 male patients that underwent elective arthroscopic menisectomy or diagnostic arthroscopy of the knee, preoperative and(More)
UNLABELLED Backround: The role of hyperhomocysteinemia as an independent risk factor for venous thrombosis after lower limb arthroplasty remains questionable. The objective of this study is to determine the relationship between hyperhomocysteinemia and postoperative thromboembolic events in patients undergoing total hip or knee arthroplasty. METHOD(More)
