Canalicular adenoma of the palate: case report and literature review.

Canalicular adenoma is a rare benign salivary gland tumor of the oral cavity, typically located in the upper lip and buccal mucosa and infrequently found on the palate. The tumor is usually confined to soft tissue and rarely presents with bone erosion. A case of a large and locally-aggressive palatal canalicular adenoma is presented.

Platelet-rich plasma: Growth factor enhancement for bone grafts.

Platelet-rich plasma is an autologous source of platelet-derived growth factor and transforming growth factor beta that is obtained by sequestering and concentrating platelets by gradient density centrifugation. This technique produced a concentration of human platelets of 338% and identified platelet-derived growth factor and transforming growth factor beta within them. Monoclonal antibody assessment of cancellous cellular marrow grafts demonstrated cells that were capable of responding to the growth factors by bearing cell membrane receptors.

Detection of radiation-induced, accelerated atherosclerosis in patients with osteoradionecrosis by panoramic radiography.

Purpose: Osteoradionecrosis (ORN) of the mandible has long been considered the most destructive complication of head and neck irradiation. Recently, therapeutic irradiation has been implicated as the cause of induced/accelerated atherosclerosis of the cervical carotid artery and subsequent stroke. Panoramic radiography, previously shown to be capable of identifying carotid artery atherosclerosis in nonirradiated individuals, was used to assess the carotid vasculature of patients being treated for ORN.
