The main clinical problems for dental implants are (1) formation of biofilm around the implant-a condition known as peri-implantitis and (2) inadequate bone formation around the implant-lack of osseointegration. Therefore, developing an implant to overcome these problems is of significant interest to the dental community. Chitosan has been reported to have good biocompatibility and anti-bacteri...
OBJECTIVES To determine the difference in light reflection of oral mucosa covering titanium (Ti) or zirconia (ZrO(2)) abutments as it relates to the thickness of the covering mucosa. MATERIAL AND METHODS Fifteen anterior implants (Astra Osseo speed(®)) in 11 patients were fitted with a Ti or a ZrO(2) abutment (cross-over, within-subject comparison). Hyper-spectral images were taken with a cam...
Approximately one-third of patients with myelodysplastic syndrome (MDS) receiving allogeneic hematopoietic stem cell transplantation (HSCT) are cured by this treatment. Treatment failure may be due to transplant complications or relapse. To identify predictive factors for transplantation outcome, we studied 519 patients with MDS or oligoblastic acute myeloid leukemia (AML, <30% marrow blasts) w...
There is a growing interest in the use of peripheral blood stem cells (PBSC) for allogeneic transplantation. This is due in part to the idea that, as with autologous transplantation, increasing the number of allogeneic hemopoietic progenitors infused may lead to reduced complications. However, introducing the PBSC technique into allogeneic transplants implies theoretical as well as ethical prob...
We have evaluated the difference in the migration patterns over two years of two cementless stems in a randomised, controlled trial using radiostereophotogrammetric analysis (RSA). The implants studied were the Furlong HAC stem, which has good long-term results and the Furlong Active stem, which is a modified version of the former designed to minimise stress concentrations between the implant a...
Allogeneic transplants with PBSC are rapidly expanding, but a number of problems concerning both donors and recipients are still unsolved. GITMO (Italian Bone Marrow Transplant Group) has established a committee for allogeneic PBSC transplants. We present here an analysis of the main aspects of this evolving area and suggest revised guidelines for the use of allogeneic PBSC transplantation.
BACKGROUND Allogeneic stem cell transplantation is a potentially curative treatment for myelofibrosis, although its use is limited by a high rate of transplant-related mortality. In this study, we evaluated the outcome of patients with myelofibrosis who underwent allogeneic stem cell transplantation, and the impact of prognostic factors. DESIGN AND METHODS One hundred patients were transplant...
