Background: In several conditions we have face cranial bone defects. Reconstruction of these defects remains one of the most challenging problems encountered by craniofacial surgeons. Objective: To evaluate bone repair in cranial bone defects by use of an implant made of octacalcium phosphate in combination with bone matrix gelatin (OCP/BMG). Methods: We used 40, 5–6-week-old male Sprague-Dawle...

conclusion for the identification of nasal bone fractures, ct was significantly superior to conventional radiography. although a staff radiologist showed better values in the identification of nasal bone fracture and differentiation between depressed and non-depressed fractures than a trainee, there was no statistically significant difference in the interpretation of conventional radiography an...

The treatment of non union and delayed union of fractures and also defects resulting from bone cysts or bone tumors by bone grafting is reported and also we have used it. In these Papers the results of bone grafting for surgical treatment of 23 war injured patients with bone lost is reported, and our results were good. 

background mandibular continuity defects occur after tumor resection, maxillofacial injury, or osteomyelitis. despite the current availability of a plethora of treatment modalities, bone substitutes, and various clinical adjuncts, an exact reconstructive recapitulation of large bony defects continues to be beyond reach. in this clinical pilot study, we report a novel method for reconstruction o...

Introduction: Gold standard for alveolar cleft bone grafting is autogenous bone. Advantage of adding the growth factors to the bone is established, so adding PRF to the autogenous bone may have beneficial effects. Methods:  Platelet-rich plasma admixed with autogenous bone and as a biologic membrane over the bone grafted alveolar cleft was used. Results:  Autogenous bone in all (four cases...

statement of problem: it is not known whether endochondral and intramembranous bones have distinct biological characteristics. octacalcium phosphate (ocp), a hydroxyapatite precursor, has been reported to stimulate bone formation after being implanted in parietal bone defects of rats. purpose: the present study was designed to investigate the response of endochondral and intramembranous bones t...

Introduction One of the important applications of nuclear physics in medicine is the use of radioactive elements as radiopharmaceuticals. Metastatic bone disease is the most common form of malignant bone tumors. Samarium-153-ethylene diamine tetramethylene phosphonate (153Sm-EDTMP) as a radiopharmaceutical is used for pain palliation. This radiopharmaceutical usually emits beta particles, which...

A case of malakoplakia and papillary urothelial carcinoma of the urinary bladder is reported. In this case, malakoplakia was an incidental finding in a biopsy of the urinary bladder of a 74-yr old female, who presented with hematuria. The biopsy showed a low-grade papillary urothelial carcinoma in close association with malakoplakia. This is a rare association of these lesions.
