BEST PR ACTICES 14 SEPTEMBER 2018 | Med Esthetics © GETTY IMAGES A study published in Plastic and Reconstructive Surgery (online July 2, 2018) revealed that human adipose cells transplanted into the scalps of mice caused a new layer of murine fat to form at the periphery of the graft. And the effect was enhanced when stromal vascular fraction (SFV) and a porcine extracellular matrix (Adipogel) was added to the grafted fat. For "Fate of free fat grafts with or without adipogenic adjuncts to enhance graft outcomes," Australian researchers Howard H. Tang, MBBS, et al, implanted human lipoaspirate into the scalps of immunodefi cient mice, with and without SVF and Adipogel. Volume retention as well as the composition of implanted or regenerated tissue was evaluated at 6 and 12 weeks. At 12 weeks, almost all of the human adipocytes had died, but a layer of host-derived adi- pose tissue had formed peripheral to the graft. The group that received fat plus SFV and Adipo- gel showed the greatest regeneration of new fat. The authors hypothesize that the fat regenera- tion may have been driven by the presence of the dying human adipocytes and enhanced with adipogenic adjuncts, noting "Future research should perhaps focus not only on improving graft survival but also enhancing the adipogenic environment conducive to fat regeneration." STRATEGIES THAT REDUCE RISK OF MALPRACTICE CLAIMS Plastic surgery practices that take part in in- surance carrier-provided malpractice training courses and offer procedure-specifi c patient education brochures are less likely to be sued for medical malpractice, according to a study published in Aesthetic Surgery (July 2018). Piper Boyll, BsC, of the University of Arizona College of Medicine, et al, emailed a prospective multiple choice questionnaire to all members of the American Society for Aesthetic Plastic Surgery (ASAPS) to evaluate attitudes and practices of informed consent in relation to medical malpractice. After reviewing the 129 returned questionnaires that were eligible for analysis, the researchers determined that surgeons who provided pro- cedure-specifi c brochures to their patients were signifi cantly less likely to be sued for medical malpractice than those who did not, as were surgeons who participated in mal- practice carrier-required courses on avoiding medical malpractice litigation.
