The effects of the use of platelet-rich plasma gel on local recurrence in an animal model of human fibrosarcoma.

Background: Platelet-rich-plasma (PRP) is largely used, thanks to its properties, as wound therapy after surgical resection. Several studies and clinical findings have demonstrated that the PRP can accelerate the regeneration and the repair of tissues through the action of the platelet-derived growth factors.

Material And Methods: Our study aimed to investigate the effects of PRP-gel on the rate of tumor relapse by using a mouse model of Human Fibrosarcoma (HF).

The natural phosphoinositide derivative glycerophosphoinositol inhibits the lipopolysaccharide-induced inflammatory and thrombotic responses.

Inflammatory responses are elicited through lipid products of phospholipase A activity that acts on the membrane phospholipids, including the phosphoinositides, to form the proinflammatory arachidonic acid and, in parallel, the glycerophosphoinositols. Here, we investigate the role of the glycerophosphoinositol in the inflammatory response. We show that it is part of a negative feedback loop that limits proinflammatory and prothrombotic responses in human monocytes stimulated with lipopolysaccharide.

Autologous Platelet Gel Improves Bone Reconstruction of Large Defects in Patients with Bone Giant Cell Tumors.

Background/aim: Giant cell tumors are mostly benign but locally aggressive tumors. The excision of bone tumors can result in large defects, therefore bone reconstruction is still one the most demanding procedures in orthopedic surgery. Our study addresses the opportunity for improving surgical outcome by employing β-tricalcium phosphate (β-TCP) with platelet-rich plasma (PRP) at the surgical site.

Use of allogeneic platelet gel in the management of chemotherapy extravasation injuries: a case report.

The allogeneic platelet (PLT) gel offers to be a valid supportive measure in the management of chemotherapy extravasation injuries. We report a case of a 58-year-old patient with multiple myeloma enrolled for high-dose chemotherapy and autologous stem cell transplantation. As pretransplant therapy, the patient received induction therapy with bortezomib, adriblastina, and desametazone.

Distribution pattern of hepatitis C virus genotypes and correlation with viral load and risk factors in chronic positive patients.

Objective: Hepatitis C virus (HCV) has emerged as a leading cause of chronic hepatitis, liver cirrhosis and hepatocellular carcinoma worldwide. The purpose of this study was to describe the distribution pattern of HCV genotypes in chronic hepatitis patients in the Campania region of southern Italy and estimate their association with risk factors and viral load.

Materials And Methods: 404 consecutive HCV ribonucleic acid-positive patients were included in the study.

HBV transmission from an occult carrier with five mutations in the major hydrophilic region of HBsAg to an immunosuppressed plasma recipient.

We describe the case of transmission of an HBsAg-negative hepatitis B infection to an immunosuppressed patient by plasma donation from an HBsAg-negative subject, but with very low serum HBV DNA (about 50 IU/ml) and five mutations in the major hydrophilic region of HBsAg.

Age and gender distribution of hepatitis C virus genotypes in the metropolitan area of Naples.

Objective: To assess any time-related variations in the distribution of hepatitis C virus (HCV) genotypes in the metropolitan area of Naples, Italy.

Methods: HCV genotypes were analysed in 255 HCV RNA-positive patients with chronic HCV infection, observed from 2009 to 2011, and compared with data pertaining to a sample of 176 HCV RNA-positive patients observed from 2006 to 2008.

Results: In both periods of analysis, genotype 1b was predominant (51.

Platelet gel in cutaneous radiation dermatitis.

Introduction: Radiotherapy, alone or in combination with chemotherapy and/or surgery, is a fundamental and irreplaceable method of treating tumours. Nonetheless, although the technological advances made during recent years and the associated improvements in this type of treatment have reduced the incidence of complications, 5-15 % of patients still experience damage to the healthy tissues exposed to radiation. Cutaneous and mucosal lesions are severe collateral effects of radiotherapy that have an enormous impact on a patient's quality of life.
