In patients presenting extensive burns, these therapies could be useful in the acute and chronic phases of wound healing. However, performing liposuction to harvest fat and isolate cells from these often critically ill patients is not an option. Some researchers collected burn surgical discards and isolated cells that showed multi-lineage differentiation. Therefore our aim was to provide an analysis of the literature regarding the use of these adipose stem cells obtained from excised wounds of burn patients. The most relevant in vivo studies are reported.

BACKGROUND:
There is an abundance of literature supporting the efficacy of fat grafting in aesthetic and reconstructive cases. There has been a recent emphasis on the regenerative capacity of adipose-derived stem cells and their utility in the improvement of wound healing and scarring provided by their cytokine and growth factor profiles. Despite the wealth of evidence supporting their efficacy, little attention has been paid to their utility in burn treatment. The authors' purpose was to provide an analysis of the literature regarding the use of fat grafting and regenerative cells in the treatment of burn wounds to guide surgeons and scientists on their clinical use.
METHODS:
A systematic review of the literature was performed by a thorough search of 12 terms using the PubMed, Medline, and Cochrane databases. Two hundred forty-one articles were subject to evaluation by predetermined inclusion and exclusion criteria.
RESULTS:
Six murine and 12 human studies were selected, including case-control studies, case series, and case reports. They describe histologic and clinical effects of fat grafting and regenerative cell therapy, including improvements in burn scar size and texture, enhanced angiogenesis, decreased inflammation, alleviation of pain, and return of function.
CONCLUSIONS:
There is a dearth of randomized controlled trials and quantitative analysis supporting the efficacy of fat grafting and adipose regenerative cells in burns. However, the subjective improvements in scars are encouraging. The authors hope that this review will be a foundation for future studies and will highlight the breadth of knowledge yet to be explored by this therapy.

Their ease of isolation, expansion and reduced ethical concern, coupled with their ‘plastic’ immune functions and homing abilities make MSCs an appealing choice as cellular vehicle for drug delivery, including the delivery of RNA.
However, while MSCs are currently listed for thousands of clinical trials, there are many confounding factors that have yet to be elucidated. In this review, we address many of the benefits of MSCs as therapeutic agents, and discuss confounding factors that require further scientific exploration.

Therefore the importance of cultivating a positive online reputation can't be ignored. This online presence and reputation is built primarily around a personal website, professional listings, ratings, profiles, patient reviews and social networking. While personal and professional websites are often not an option for plastic surgery trainees, online presence can still be maintained by careful use of high-traffic social sharing sites. In this article, we discuss ways that trainees and junior plastic surgeons can tailor their online profile to establish an internet presence without investing in a personal website.

Therefore, we compared the yield and cellular composition of SVCs obtained from lipoaspirates after centrifugation, vortexing and collagenase digestion.

However, complication rates in super obese patients or patients receiving large volume reductions are high, ranging from 35 to 78%. These complications include delayed healing, infection, seroma, nipple-areolar complex necrosis, fat necrosis and development of hypertrophic scars.
AIMS:
This study aimed to determine whether a modification to the standard Wise-pattern reduction technique, an expanded inframammary fold skin triangle, produces improved outcomes in high-risk large volume breast reduction patients. We report that this modification leads to improved outcomes by decreasing wound complications and improving aesthetic appearance.
SETTINGS AND DESIGN:
Twenty-two patients received the inferior pedicle Wise-pattern reduction mammaplasty, which was modified to include an 8 cm wide inferior pedicle. This pedicle was de-epithelialized and an 8 × 3 cm(2) triangle of skin was preserved at the inferior base to reduce tension at the triple point, inverted T-closure.
MATERIALS AND METHODS:
A retrospective review was performed on all patients who underwent reduction mammaplasty with the expanded inframammary fold (eIMF) technique as well as all patients who received the standard wise pattern technique.
STATISTICAL ANALYSIS USED:
A student t-test was performed for both reduction populations using SPSS software package. Statistical significance was defined as P < 0.05.
RESULTS:
The average patient age was 32.25 years old (range 18-59), average BMI was 35.0, and average tissue mass removed per breast was 1378.39 g. The modified technique was found to produce a statistically significant (P < 0.05) increase in the amount of breast tissue removed (693.96 g increase in the left and 571.21 g in the right) as well as a statistically significant (P < 0.05) reduction in dehiscence (75% reduction) and post-operative infection (44.10%).
CONCLUSIONS:
This method is an easily reproducible and reliable technique that produces a favourable cosmetic outcome with acceptable, sustainable results in high-risk reductions in obese patients.

Current autologous fat transfer techniques have several limitations, including availability, donor site morbidity, and unpredictable rates of resorption. We present an extracellular matrix (ECM) biomaterial derived from human adipose tissue as an off-the-shelf alternative for soft-tissue volume restoration and compare clinically relevant rheologic properties.
Objectives To determine the rheologic properties of adipose-derived ECM and to compare it with lipoaspirate, calcium hydroxylapatite, and cross-linked hyaluronic acid.
Design, Setting, and Participants Adipose-derived ECM (n = 4), lipoaspirate acquired from aesthetic liposuction (n = 4), calcium hydroxylapatite (n = 4), and cross-linked hyaluronic acid (n = 4) were obtained to determine the viscoelastic properties.
Interventions Dynamic frequency oscillation measurements were conducted using a rheometer (ARES-G2; TA Instruments). All injections were performed using a 20-gauge needle, and all measurements were performed using serrated 25-mm parallel-plate geometry with a 1.0-mm gap at 37°C.
Main Outcomes and Measures Oscillation measurements for storage modulus, a measure of the elastic properties, and complex viscosity were obtained over an angular frequency range of 0.01 to 100 rad/s.
Results At 1 Hz, adipose-derived ECM had a mean (SD) storage modulus of 713.2 (42.9) Pa and a mean (SD) complex viscosity of 115.8 (6.9) Pa/s. Lipoaspirate had a mean (SD) storage modulus of 382.1 (66.8) Pa and a mean (SD) complex viscosity of 61.5 (10.7) Pa/s. Calcium hydroxylapatite had a mean (SD) storage modulus of 1122.1 (67.1) Pa and a mean (SD) complex viscosity of 207.2 (11.6) Pa/s. Cross-linked hyaluronic acid had a mean (SD) storage modulus of 63.9 (3.0) Pa and a mean (SD) complex viscosity of 10.9 (0.5) Pa/s.
Conclusions and Relevance Of the 4 materials tested, calcium hydroxylapatite has the highest mean storage modulus and mean complex viscosity, and hyaluronic acid has the lowest. The viscoelastic properties of adipose-derived ECM are most similar to those of lipoaspirate, suggesting that it may be an ideal candidate for soft-tissue reconstruction.

Components separation has been proposed as a means to close large ventral hernia without undue tension. We report a modification on open components separation that allows for the incorporation of onlaid noncrosslinked porcine acellular dermal matrix (Strattice, LifeCell Corp, Branchburg, NJ) as a load-sharing structure. Methods. This was a retrospective case series including all cases using Strattice from July 2008 through December 2009. Data evaluated included patient demographics, comorbidities associated with risk of recurrence, hernia grade, and postoperative complications. The primary outcomes were hernia recurrence and surgical site occurrences. Results. There were 58 patients; 60.8% presented with a recurrent incisional hernia. Average length of follow-up was 384 days. There were 4 hernia recurrences (7.9%). Complications included surgical site infection (20.7%), seroma (15.5%), and hematoma (5%) requiring intervention. Four deaths occurred in the series due to causes unrelated to the hernia repair, only 1 within 30 days of operation. Conclusions. This series demonstrates that components separation reinforced with noncrosslinked porcine acellular dermal matrix onlay is an efficacious, single-stage repair with a low rate of recurrence and surgical site occurrences.

Os autores descrevem um modelo de treinamento acessível, prático e fácil, que utiliza retalho abdominal proveniente de abdominoplastias. O calibre dos vasos epigástricos superficiais encontrados nos retalhos abdominais excisados variou de 1,2 mm a 2 mm, dependendo do índice de massa corporal da paciente no pré-operatório. Esse retalho permitiu o treinamento de anastomoses microcirúrgicas em vasos de diferentes calibres. Esses vasos permaneciam com pequena quantidade de sangue em seu lúmen, o que permitia testar a qualidade e a patência das anastomoses. Esse modelo de treinamento em vasos abdominais humanos, quando comparado aos modelos animais ou inanimados, permite transição mais rápida e real aos pacientes. A prática de dissecção e de anastomoses terminoterminais e terminolaterais de uma maneira efetiva e prática aperfeiçoa a destreza cirúrgica.

However, postoperative wound complications remain common. The benefits of negative-pressure wound therapy (NPWT) in the management of open abdominal wounds are well described in the literature. Our study investigates the effects of incisional NPWT after primary closure of the abdominal wall. to analyze the outcomes of patients treated postoperatively with incisional NPWT versus conventional dry gauze dressings. Patient information collected included history of abdominal surgeries, smoking status, and body mass index. Postoperative complications were analyzed using W 2 exact test and logistic regression analysis. Results: Fifty-six patients were included in this study; of them, 23 were treated with incisional NPWT, whereas 33 received conventional dressings. The rates of overall wound complications in groups I and II were 22% and 63.6%, respectively (P = 0.020). The rates of skin dehiscence were 9% and 39%, respectively (P = 0.014). Both outcomes achieved statistical significance. Rates of infection, skin and fat necrosis, seroma, and hernia recurrence were 4%, 9%, 0%, and 4% for group I and 6%, 18%, 12%, 9% for group II, respectively. Conclusions: This study suggests that incisional NPWT following abdominal wall reconstruction significantly improves rates of wound complication and skin dehiscence when compared with conventional dressings. Prospective, randomized, controlled studies are needed to further characterize the potential benefits of this therapy on wound healing after abdominal wall reconstruction.

During these sessions, we rarely discuss day to day events that are happening in our field, new discoveries, meetings we’ve attended. As we are living in an era of social technologies that empower users to generate content and share information in real time1, we felt it was imperative we be informed and able to address questions of our patients and the public, about issues that may evolve in the online world. As most of us incorporate social media to communicate with friends, we have noticed recently that numerous Plastic Surgeons, Universities, Hospitals, societies, organizations, meetings and journals have incorporated the social network to benefit themselves and communities they serve. Methods: As there is no dedicated time or place to discuss these issues with our peers, and with many academic plastic surgeons not having the time or interest to consult daily social media, like those in private practice who do mainly to recruit patients, we created “Plastic Surgery Newsweek in 5 minutes”. Each week after grand rounds, the first author takes 5 minutes to go over the headlines in our field. By having an account with several social network websites, and by “Friending” or “Liking” societies (ASPS, ASAPS), journals (PRS, ASJ) or others, we receive updates, each day, that we can streamline and share with our peers. Results: Since we started in July 2011, we discussed relevant issues such as the ALCL breast implant scandal, followed ongoing FDA debates on stem cells, presented highlights of national and international meetings, shared most viewed articles2, to name a few. This initiative has been a success and received positive evaluations of all that attended throughout the weeks. Conclusion: This represents one of many opportunities through which social network can keep us apprised of the latest trends in our field and can serve as a complement for ongoing learning at other institutions.

Furthermore, others have noted aesthetic problems with closure of the umbilicus due to apparatus port proximity. Currently, no clinical protocol or formal industry guidance for LAGB apparatus management during abdominoplasty is available in the medical literature. In this article, the authors describe their procedure for safe LAGB apparatus management during abdominoplasty and illustrate key surgical principles by presenting unique cases from their series of 20 patients treated with this technique.

Lipoaspirate had a mean (SD) storage modulus of 382.1 (66.8) Pa and a mean (SD) complex viscosity of 61.5 (10.7) Pa/s. Calcium hydroxylapatite had a mean (SD) storage modulus of 1122.1 (67.1) Pa and a mean (SD) complex viscosity of 207.2 (11.6) Pa/s. Cross-linked hyaluronic acid had a mean (SD) storage modulus of 63.9 (3.0) Pa and a mean (SD) complex viscosity of 10.9 (0.5) Pa/s.
Conclusions and Relevance Of the 4 materials tested, calcium hydroxylapatite has the highest mean storage modulus and mean complex viscosity, and hyaluronic acid has the lowest. The viscoelastic properties of adipose-derived ECM are most similar to those of lipoaspirate, suggesting that it may be an ideal candidate for soft-tissue reconstruction.

Methods/Technique: With the help of residents, the encouragement of attendings, this subject was chosen as our thesis for the obtention of the Plastic Surgery diploma. We pioneered a project, in which we studied the most practical methods of preparation of fat to obtain less resorption and better fat grafting results overtime. This study led to several publications in peer-reviewed Plastic Surgery journals and many presentations at international and national meetings. When we start writing and publishing, at first our main goal is to add a long list of publications on our curriculum vitae, second comes the desire to be recognized by our peers, then we wish to contribute to the Plastic Surgery literature and ultimately make a significant difference in our field, by being useful to other plastic surgeons in their daily practice and to residents/fellows in training.
Results/Complications: Conducting Research, brings us close to Plastic Surgeons around the world, their ideas and allows us to make valuable exchanges through meetings, publications, fellowships. Most importantly research makes us question our choices and actions, compare our procedures with others, have our peers criticize our work, or serve as a bridge for other projects. Reporting series of hundreds of patients with descriptive images, sharing what we do in a country is advantageous to the surgeons, authors, the hospital, city, country where the procedures are performed and of course the ultimate goal, the field of Plastic Surgery. The industry also benefits from these studies as surgeons are encouraged to make more informed decisions on product choices. Research is demanding; it requires lots of paperwork, institutional review board and animal committee’s approvals, grant applications, dedication and time. All research is good, even reporting negative or unexpected outcomes, as all we know is still infinitely less than all that remains to be known. Journals and meetings are not only looking for new things per se, as almost everything has been written. They are looking rather for interesting approaches to conditions, improvement of procedures and most importantly Evidence based practice. It’s so interesting to see how we have evolved over the years. At a certain point in our career, we feel comfortable, when we obtain good results with a procedure, we like stability and consistency, and fear change. But nowadays, we are faced with constant changes with the advances in technology, we must accept them and adapt as some procedures are becoming easier with technology. Information flows quickly with social media, our society is internet-driven and we need to keep pace.
Conclusion: Overall, we Plastic Surgeons are all Creators, Innovators. Yes, in our operating room, clinic, when we stay up late at night thinking of patients or procedures, the difference is that some of us have time or make time to actually report the results. History has come full circle, we recently find ourselves going back to bench research with basic sciences and animal studies, to understand our clinical results, establish guidelines of care and open horizons working with other specialists (biochemists, physicists). It is the plastic surgeon that can commonly make the transition of bench research into a in vivo established procedure, rendering research more translational, more practical. The world no longer needs to dream about face transplant as a possibility in the future, as these efforts are in the present, with hand transplantation being almost routine in some institutions. Stem cells are at the forefront of our specialty with many registral trials around the world.We are living the golden age of plastic surgery again and again. We are fortunate to be practicing a specialty that has so much diversity and allows us to be creative, inventive and adventurous.
METHODS: We performed a retrospective chart review of patients having undergone abdominal wall reconstruction with the components separation technique and the use of porcine acellular dermal matrix, from September 2008 to May 2011. This population of patients had primary closure of their incisions and were treated in the immediate postoperative period with either incisional NPWT or conventional dry gauze dressings. Patient information collected included history of abdominal procedures, smoking status and body mass index. Postoperative complications were analyzed using chi-square exact test and logistic regression analysis.
RESULTS: Datas from 56 patients were included in this study. Group I included 23 patients treated with incisional NPWT and Group II included 33 patients who had conventional dry gauze dressings placed on their closed incisions. The rates of overall wound complications in Groups I and II were respectively 22% and 63.6%, (p=0.020). The rates of skin dehiscence were respectively 9% and 39%, (p=0.014). Both postoperative outcomes achieved statistical significance. Rates of infection, skin and fat necrosis, seroma and hernia recurrence were respectively 4%, 9%, 0% and 4% for group I and 6%, 18%, 12%, 9% for group II.
CONCLUSIONS: This study suggests that the use of NPWT on closed incisions of patients having undergone ventral hernia repair, significantly improves the rates of postoperative wound complications and skin dehiscence when compared to those who had conventional dry gauze dressings placed on their closed wounds. Prospective, randomized, controlled sutides are needed to further characterize the potential benefits of this therapy on wound healing after abdominal wall reconstruction."
