Profiling osteogenesis

Expression profiling reveals alternative macrophage activation and impaired osteogenesis in periprosthetic osteolysis.

Interactions between periprosthetic cells and prosthetic wear debris have been recognized as an important event in the development of osteolysis and aseptic loosening. Although the ability of wear debris to activate pro-inflammatory macrophage signaling has been documented, the full repertoire of macrophage responses to wear particles has not been established. Here, we examined the involvement ...

Distraction Osteogenesis

Distraction osteogenesis is increasingly used for bone lengthening of facial skeleton. Distractors may be intraoral and extraoral. The authors present development of distractors and their use for treatment of facial bones. Procedure may be used for treatment of malformations, syndroms, posttraumatic bone defects and deformities. The advantage of a distractor are a simple and fast procedure, sho...

Distraction Osteogenesis

Osteogenesis imperfecta.

Our clinical files on osteogenesis imperfecta are brought up-to-date reviewing a total of 33,555 cases admitted between 4/XII/48 and 31/VIII/76. From these, 5 clinical cases were found. The extreme rareness of this regional pathology in our Cátedra y Sericio de Pediatría, which is the largest concentration center in Paraguay had led us to make this publication. From our casuistics, we may singl...

Distraction Osteogenesis

Distraction osteogenesis is a treatment modality for the correction of bone anomalies and abnormalities which are either pathological or developmental in origin. Its use in the field of dentistry began in the late twentieth century. Successfulresults from clinical trials has led to more researchers to explore this field. Its use in dentistry involves the correction of craniofacial anomalies, al...
