Vascular Pedicle and Microchannels: Simple Methods Toward Effective In Vivo Vascularization of 3D Scaffolds.

Poor vascularization remains a key limiting factor in translating advances in tissue engineering to clinical applications. Vascular pedicles (large arteries and veins) isolated in plastic chambers are known to sprout an extensive capillary network. This study examined the effect vascular pedicles and scaffold architecture have on vascularization and tissue integration of implanted silk scaffolds.

Fate of Free Fat Grafts with or without Adipogenic Adjuncts to Enhance Graft Outcomes.

Background: Free fat grafting is popular, but it is still unclear how it works. Although focusing on graft survival seems an obvious direction for improving clinical results, the authors' research suggests that long-term volume retention is in part attributable to new fat regeneration. Measures to facilitate adipogenesis may therefore be equally important.

Steroid therapy for problematic proliferating haemangioma.

Aim: To evaluate the effectiveness and the safety of systemic and intralesional steroid therapy for problematic proliferating haemangioma.

Method: 233 patients with haemangioma were identified from our vascular anomalies database 1996-2007. 46 (36%) out of 129 patients with proliferating haemangioma required intervention.

Ivory osteoma of the craniofacial skeleton.

The authors describe the clinical presentation, investigation, and surgical management of two cases of benign ivory osteoma of the craniofacial skeleton. In the first case, a bony mass located over the frontal region had become a cosmetic burden to the patient, and she requested removal with minimal morbidity. Accordingly, an endoscopic procedure, with minimal access incisions located behind the hairline, was devised.
