INTRODUCTION: Osteosarcoma is an aggressive primary bone tumor composed of connective tissue cells directly producing osteoid and bone. Prosthetic rehabilitations in post-oncological patients after bone reconstruction are not substantially different than those of patients affected by severe atrophy of upper or lower jaw after bone reconstruction. The treatment for patients with a malignant neoplasia of the oral cavity requires multidisciplinary approach by a team of different specialists that follow the patient through the phases of diagnosis, therapy and oral rehabilitation...

Autogenous bone grafts are the gold standard for reconstruction of atrophic jaws, pseudoarthroses, alveolar clefts, orthognathic surgery, mandibular discontinuity, and augmentation of sinus maxillary. Bone graft can be harvested from iliac bone, calvarium, tibial bone, rib, and intraoral bone. Proximal tibia is a common donor site with few reported problems compared with other sites. The aim of this study was to evaluate the use of proximal tibia as a donor area for maxillofacial reconstructions, focusing on quantifying the volume of cancellous graft harvested by a lateral approach and to assess the complications of this technique...

Dyskeratosis congenita is a rare congenital telomeropathy characterized by cutaneous and nail dystrophy, oral leukoplakia, and bone marrow failure. Pulmonary fibrosis and cancers are late manifestations. Allogeneic hematopoietic stem cell transplant represents the only cure for those with bone marrow failure with this disease, but outcomes reported are overall poor, with organ toxicities, graft failure, and graft-versus-host disease as main issues. Although reduced intensity conditioning regimens seem to be related to better outcomes, a standard regimen for dyskeratosis congenita has never been defined...

An antimicrobial decapeptide, KSL-W (KKVVFWVKFK-CONH₂), which could maintain stable antimicrobial activity in saliva, has therefore been widely used to inhibit biofilm formation on teeth and prevent the growth of oral microorganisms for related infectious diseases treatment. In order to control the release of KSL-W for long-term bacterial resistance, KSL-W-loaded PLGA/chitosan composite microspheres (KSL/PLGA/CS MSs) were prepared by electrospraying and combined crosslinking-emulsion methods. Different formulations of microspheres were characterized as to surface morphology, size distribution, encapsulation efficiency, in vitro drug release, and antimicrobial activity...

Dear Editor, An 83-year-old woman developed yellow-brownish infiltrates, nodules, and tumors mimicking xanthomas, mostly involving the periorbital and chest area within three months (Figure 1). She had no abnormalities in serum cholesterol or triglycerides levels. A detailed laboratory analysis revealed the presence of mild monoclonal gammopathy with a presence of immunoglobulin G (IgG) kappa light chains; however, according to hematologist consultation, it did not require medical intervention. Imaging assessment and ultrasound examination did not show any specific involvement of internal organs...

BACKGROUND: Insertion of an implant in the edentulous posterior maxilla is a challenging procedure because of poor bone quality and increased pneumatization of the maxillary sinus after tooth extraction. To increase the amount of bone, several surgical bone grafting techniques have been used-with considerable morbidity for patients. Osteotome sinus floor elevation (OSFE) is a less invasive technique. The clinical and radiographic outcome of 53 implants placed with this technique without bone graft has been reported previously...

INTRODUCTION: Exchange nailing is most acceptable for treating hypertrophic non-union of the long bones, requiring the removal of previously fixed implant. However, its main effect of mechanical stabilization is controversial in non-isthmal area. We hypothesized that minimally invasive plate augmentation over the non-union site may have a better option, without the need of bone grafting or removing pre-existing implants. MATERIALS AND METHODS: Seventeen patients with hypertrophic non-union of the long bones between 2010 and 2014 on radiography who previously underwent intramedullary (IM) nailing or plate osteosynthesis for long-bone fractures were included...

A pediatric patient presenting with an open forearm fracture with segmental defect is rare, and the pediatric orthopedic literature to guide treatment is sparse. There are several described methods to treat the defect, including bone grafting and bone transport techniques. In addition, there are reports of fibular regeneration after resection if the periosteum is left intact. We present a case report of complete regeneration of over half of a pediatric radial shaft with an intact periosteum, after traumatic extrusion from an open fracture...
