Platelet-rich plasma (PRP) is a natural concentrate of autologous blood growth factors experimented in different fields of medicine in order to test its potential to enhance tissue regeneration. The aim of our study is to explore this novel approach to treat degenerative lesions of articular cartilage of the knee. One hundred consecutive patients, affected(More)
BACKGROUND There is great interest in the use of bone substitutes to improve bone repair. We compared the osteogenic potential of lyophilized bone chips combined with platelet gel, or with platelet gel and bone marrow stromal cells, with that of lyophilized bone chips alone in the healing of a high tibial osteotomy. METHODS A prospective, randomized,(More)
A retrospective study of 37 patients with haematological malignancy (21 acute myeloid leukaemia, 11 acute lymphoid leukaemia, two lymphoma, two hairy cell leukaemia, one Hodgkin's disease) and histologically documented mucormycosis was conducted to evaluate the clinical characteristics and ascertain the factors which influenced the outcome from mycotic(More)
To compare the safety and efficacy of two different approaches of platelet-rich plasma (PRP) production methods as intra-articular injection treatment for knee cartilage degenerative lesions and osteoarthritis (OA). The study involved 144 symptomatic patients affected by cartilage degenerative lesions and OA. Seventy-two patients were treated with 3(More)
BACKGROUND Platelet rich plasma (PRP), a blood-derived product rich in growth factors, is a promising treatment for cartilage defects but there is still a lack of clinical evidence. The aim of this study is to show, through a randomized double blind prospective trial, the efficacy of this procedure, by comparing PRP to Hyaluronic Acid (HA) injections for(More)
Platelet-rich plasma (PRP) therapy is a simple, low-cost and minimally invasive method that provides a natural concentrate of autologous blood growth factors (GFs) that can be used to enhance tissue regeneration. In a previous analysis of a 12-month follow-up study, promising results were obtained when treating patients affected by knee degeneration with(More)
Myelodysplastic syndromes (MDS) are a group of hematopoietic disorders characterized by uni- or multilineage maturation defects of the bone marrow. Controversial therapeutic results have been obtained using growth factors or differentiating agents such as 13-cis retinoic acid. In this pilot study we evaluated the effects of all-trans retinoic acid (ATRA) in(More)
Twenty-eight patients with poor prognosis acute myeloid leukemia (AML) received therapy with two courses of fludarabine 30 mg/m2/day + ara-C 2 g/m2/day (days 1-5) and G-CSF 5 mg/kg/day (FLAG) (from day 0 to polymorphonuclear recovery). Eighteen patients were considered 'refractory' (eight primarily resistant, five relapsing within 6 months of initial(More)
Studies on new procedures for bone reconstruction suggest that autologous cells seeded on a resorbable scaffold can improve the treatment of bone defects. It is important to develop culture conditions for ex vivo expansion of stromal stem cells (SSC) that do not compromise their self-renewing and differentiation capability. Bone marrow SSC and platelet gel(More)
