Osteogenic capacities of tibial and cranial periosteum: a biochemical and histologic study.

The periosteum has an important role in bone regeneration. The purpose of this study was to evaluate and compare the osteogenic capacities of tibial and cranial periosteum. To achieve this, 44 New Zealand male rabbits were divided into two groups, each consisting of 22 rabbits.

[Surgical coverage technics of pressure sores and their outcomes].

Background: We reviewed the outcome of 66 patients with 100 pressure sores between 1984 and 2002.

Methods: In the current study, 100 pressure sores in 66 patients (45 male, 21 female; mean age 39.4; range 13 to 80 years) who underwent surgical repair of pressure sores reconstructed using myocutaneous or fasciocutaneous flaps, skin grafts, excision and closure.

Free fibula flap mandible reconstruction in benign mandibular lesions.

The mandible may be affected by a variety of pathological conditions such as ameloblastomas, odontogenic keratocysts, central giant cell granulomas, fibro-osseous lesions, and osteomas. They generally are benign, and conservative treatment can be enough in most of the cases. However, they can be clinically aggressive, and especially ameloblastomas, odontogenic keratocysts, and fibro-osseous lesions are prone to recur.

A rare location of benign osteoblastoma: review of the literature and report of a case.

Benign osteoblastoma is a rare primary bone tumor that constitutes approximately 1% of all primary bone tumors. Its occurrence in the craniomaxillofacial region as also rare and represents only 15% of all osteoblastomas. The tumor shows a predilection for the male gender and constitutes less than 1% of all tumors of the maxillofacial region.

Benign osteoma with Gardner syndrome: review of the literature and report of a case.

Gardner syndrome, a variant of familial adenomatous polyposis, is an autosomal dominant disease characterized by gastrointestinal polyps that develop in the colon as well as in the stomach and upper intestine (duodenum), multiple osteomas, and skin and soft tissue tumors. Cutaneous findings include epidermoid cysts, desmoid tumors, and other benign tumors. Polyps have a 100% risk of undergoing malignant transformation; consequently, early identification and therapy of the disease are critical.
