RESUMO
BACKGROUND: Local recurrence (LR) rates of dermatofibrosarcoma protuberans (DFSP) treated with different surgical modalities are unknown. OBJECTIVE: To evaluate the differences in LR rates of DFSP treated with wide local excision (WLE) versus Mohs micrographic surgery (MMS). MATERIALS AND METHODS: Pertinent studies of DFSP treated with either WLE or MMS were identified through a search of multiple databases, including Ovid MEDLINE (1946-2018), Embase (1988-2018), Web of Science (1975-2018), and Scopus (1970-2018). Comparative 2-arm and noncomparative single-arm studies were assessed through meta-analyses. RESULTS: Of the 517 studies identified, 88 met inclusion criteria (12 comparative studies; 76 single-arm studies). In the 12 comparative studies, 352 patients with DFSP underwent MMS and 777 patients with DFSP underwent WLE. The LR rate was 1.7% after MMS and 3.7% after WLE (odds ratio, 1.549; 95% CI, 0.710-3.381; p = .27). In the 76 noncomparative studies, 980 patients underwent MMS (LR rate, 1.5%; 95% CI, 0.9%-2.1%; p < .001), and 2,215 patients underwent WLE (LR rate, 9.4%; 95% CI, 7.5%-11.3%; p < .001). CONCLUSION: The LR rate of DFSP in patients treated with MMS is lower than in patients treated with WLE. Because of high rates of postoperative DFSP LR, MMS should be strongly considered when available.

BACKGROUND: The COVID-19 pandemic has brought about immense change in health care. Surgical specialties in particular have had to make major adjustments because of the cancellation of nonemergent surgeries. Aesthetic surgery fellowships are uniquely affected because of the high number of elective cases and the length of the fellowship. The impact of the COVID-19 pandemic on current and upcoming aesthetic surgery fellows has not been studied. OBJECTIVE: The aim of this article was to study the potential impact of the COVID-19 pandemic on both American Society for Aesthetic Plastic Surgeons-endorsed and nonendorsed aesthetic fellowship programs. METHODS: A 23-question anonymous web-based survey was sent to aesthetic surgery fellowship directors with an active program in the United States. Surveys were collected from April 18, 2020, through May 14, 2020, with Qualtrics and then analyzed with Microsoft Excel. A 7-question follow-up survey was sent to directors, and a 23-question survey was sent to aesthetic surgery fellows. Data for these surveys were collected from June 6, 2020, through August 18, 2020. The surveys asked questions pertaining to adjustments and impact on current fellow training, as well as possible impact on fellows starting in 2020 and 2021. RESULTS: There was a 65.5% (19 of 29) response rate for the initial director survey, a 31% (9 of 29) rate for the director follow up survey, and a 28% (9 of 32) rate for the fellow-specific survey. All directors and fellows reported that the pandemic had some impact on aesthetic fellow training. A total of 5.3% of directors reported that they believe COVID-19 would have a "significant impact" on their fellows becoming well-trained aesthetic surgeons, whereas 66.7% of fellows reported that it will have a "mild impact." Predicted impact on future fellows was not as significant. CONCLUSION: Telemedicine, educational efforts, and standardization of guidelines can be increased to minimize loss of training due to COVID-19. Ongoing evaluation and shared experiences can assist fellowships in customizing programs to provide well-rounded education during the pandemic.

BACKGROUND: Lipoplasty has undergone a series of refinements since its inception. It is now possible to apply superficial suction to enhance the outline of a muscle in order to improve the results of aesthetic lipoplasty. OBJECTIVES: The aim of this study was to summarize the available evidence on the techniques and surgical outcomes of high-definition lipoplasty (HDL) in male patients. METHODS: A systematic search across PubMed MEDLINE, Web of Science, Ovid MEDLINE In-Process & Other Non-Indexed Citations, and SCOPUS was performed in accordance with the PRISMA guidelines. Data regarding the surgical techniques, outcomes, and complications were extracted. RESULTS: Thirteen studies comprising 1280 patients fulfilled the inclusion criteria. The age of patients ranged from 18 to 71 years. The average BMI was 26.5 kg/m2. The follow-up ranged from 2 weeks to 10 years. The liposculpting concepts reported were abdominal etching, high-definition, muscular sculpture, and dynamic definition. Four studies used conventional liposuction, 3 used VASER-assisted HDL, and 6 studies used power-assisted liposculpting. Eight studies reported the use of fat grafting. All studies reported the use of postoperative garments and a well-established wound treatment protocol. Overall satisfaction ranged from 84% to 100%. The most common complications reported were fluid collection, hyperpigmentation, contour irregularities, anemia, and port dehiscence. CONCLUSIONS: A wide variety of techniques are available to perform HDL with a variable degree of definition. Careful patient selection is critical for successful results because HDL is not suitable for every patient. Finally, proper training and adequate knowledge of abdominal anatomy is necessary to avoid complications.

BACKGROUND: Cleft lip and cleft palate (CLP) are among the world's most common congenital malformation and has a higher prevalence in developing nations due to environmental and genetic factors. Global efforts have been developed in order to prevent and treat the malformation. Telemedicine has been implemented in various humanitarian global missions with success and is currently the primary means of care due to COVID-19. OBJECTIVE: To assess the benefits and barriers of telehealth in the care of patients with CLP through a global approach. METHODS: Systematic review of the PubMed and Cochrane Review databases with relevant terms related to telemedicine in cleft lip and palate surgery. RESULTS: Eight articles fit the inclusion criteria and suggested benefits with the use of telemedicine in regard to education, preoperative, and postoperative care as well as increased access to underserved populations. Barriers included connectivity and accessibility concerns. CONCLUSION: Telehealth is a beneficial way to evaluate patients with CLP in developing countries with proper care and follow-up to reduce complications and to improve health outcomes.

BACKGROUND: Autologous breast reconstruction (ABR) has grown in popularity due to improved aesthetic and long-term patient reported outcomes, but data regarding sensory reinnervation of autologous flaps remain limited. Traditionally, the lateral cutaneous branch of the fourth intercostal nerve has been used for flap neurotization, but the use of the anterior cutaneous branch of the intercostal nerves (ACB) offer a more optimal location to the microsurgical field when using internal mammary vessels for the microanastomosis. This study aimed to evaluate the optimum ACB recipient site level for sensory nerve coaptation in ABR. METHODS: Twelve hemi-chests were dissected from six fresh cadaveric females. Costal cartilages were removed and the anterior cutaneous intercostal nerve (ACB) and the lateral (subcutaneous) division of the anterior cutaneous branch (LACB) of the intercostal nerve were exposed. Anatomical measurements were recorded, and nerve samples were evaluated histologically with carbonic anhydrase staining to differentiate sensory fascicles. Assessment of fascicular diameter, axonal counts, and fascicular area were compared. RESULTS: A total of 75 nerve specimens were assessed. The ACB was identified at all levels (100%) and the subcutaneous LACB was noted consistently in the second to fourth rib space (96% cadavers), with a median length of 43, 37.5, and 37 mm, respectively. Across all rib spaces, the fascicular and axonal counts were comparable between the LACB and ACB. Nerves in the second intercostal space had a significantly larger mean fascicular area mean (112,816 ± 157,120 µm2) compared with that in the fourth (mean 26,474 ± 38,626 µm2), p = 0.03. Axonal count of sensory fascicles was the highest in the second intercostal nerves (p < 0.05). CONCLUSION: This study provides anatomical and histological basis to determine the optimum recipient site choice for sensory coaptation in microsurgical breast reconstruction. This would aid in operative decision-making regarding the ideal recipient anterior cutaneous intercostal nerve branches for recipient site coaptation in ABR.

INTRODUCTION: Although an infrequent cause of small penile size in adult men, acquired penile shortening represents a particular reconstructive challenge due to preexisting penile anatomic deformities. AIM: With numerous techniques being performed, the purpose of our study is to assess available literature on length enhancement procedures used for acquired penile shortening deformities. METHODS: A systematic review was performed using the guidelines outlined in the Preferred Reporting Items for Systematic reviews and Meta-analyses. Medline/PubMed, Scopus, and Cochrane Databases were used to identify papers on augmentation Phalloplasty in non-transgender males with acquired penile shortening from 1990 to 2018. MAIN OUTCOME MEASURE: Outcomes, complications, and patient-reported satisfaction were analyzed. RESULTS: 12 articles, involving 931 patients and 8 primary procedures, met our inclusion criteria. The majority of articles had level of evidence of 4 (83%) and Newcastle Ottawa Scale score of 6 (92%, moderate risk of bias). All studies reported mean penile length gain; however, inconsistent methodology was used when measuring penile dimensions. Mean length gain ranged from 0.6 to 6.4 cm. Overall, the mean complication rate for all techniques ranged from 0% to 50%. Post-operative satisfaction was reported in 10 (83%) studies, 7 of which used a validated scale. Patients were generally satisfied, with reported satisfaction rates ranging from 77% to 100%. CLINICAL IMPLICATIONS: While numerous procedures have been described, the significant limitations in the available data preclude identifying a single superior procedure. STRENGTHS & LIMITATIONS: The significant heterogeneity in the reported literature is a limitation of this study and highlights the need for standardized reporting. However, this study is the first to analyze augmentation phalloplasty literature in the setting of acquired penile shortening. CONCLUSION: Augmentation phalloplasty techniques for acquired penile shortening are evolving and are continuously being modified; best-practice guidelines are crucial to achieve safe and satisfactory outcomes in this population.

Abdominal wall reconstruction is indicated when 1 or more of the abdominal wall components (skin, fascia, or muscle) are either injured or absent. When faced with defects requiring flap reconstruction, the decision regarding flap choice should take into consideration the volume of soft tissue required, the extent of the defect, donor site morbidity, and prior surgical scars that affect flap vascularity. We present a case of an abdominal wall defect with limited reconstructive options in which a spare ileal bowel segment was filleted to create a seromuscular flap for improving the abdominal wall blood supply. The postoperative course was complicated by abdominal fluid collection, which resolved following an ultrasound-guided drain. The patient had normal wound healing and recovery without further postoperative complications at the 7-month follow-up. Seromuscular flaps are a practical option in the armamentarium of plastic surgeons performing abdominal wall reconstruction, especially when other alternatives are limited.

INTRODUCTION: Autologous fat grafting (AFG) is a popular and effective method of breast reconstruction after mastectomy; however, the oncological safety of AFG remains in question. The aim of this study was to determine whether AFG increases the risk of cancer recurrence in the reconstructed breast. METHODS: A matched, case-control study was conducted from 2000 to 2017 at the senior author's institution. Inclusion was limited to female patients who underwent mastectomy and breast reconstruction with or without AFG. Data were further subdivided at the breast level. χ analyses were used to test the association between AFG status and oncologic recurrence. A Cox proportional-hazards model was constructed to assess for possible differences in time to oncologic recurrence. The probability of recurrence was determined by Kaplan-Meier analyses and confirmed with log-rank testing. RESULTS: Overall, 428 breasts met study criteria. Of those, 116 breasts (27.1%) received AFG, whereas 312 (72.9%) did not. No differences in the rates of oncologic recurrence were found between the groups (8.2% vs 9.0%, P < 1.000). Unadjusted (hazard ratio = 1.03, confidence interval = 0.41-2.60, P < 0.957) and adjusted hazard models showed no statistically significant increase in time to oncologic recurrence when comparing AFG to non-AFG. In addition, no statistical differences in disease-free survival were found (P = 0.96 by log rank test). CONCLUSION: Autologous fat grafting for breast reconstruction is oncologically safe and does not increase the likelihood of oncologic recurrence. Larger studies (eg, meta analyses) with longer follow-up are needed to further elucidate the long-term safety of AFG as a reconstructive adjunct.

BACKGROUND: Penile prostheses are commonly used to achieve erectile rigidity after phalloplasty in trans masculine patients. Implantation poses significant challenges because of the delicate nature of the neophallus and lack of native erectile tissue. Many groups have developed novel phalloplasty and prosthesis insertion techniques, but none have proven superior. AIM: To analyze and aggregate reported characteristics and outcomes of penile prosthesis implantation in the trans masculine patient. METHODS: A comprehensive literature search of Medline, EMBASE, and Cochrane Registry databases was conducted for studies published through February 19, 2019, with multiple search terms related to penile prosthesis use in gender-affirming surgical procedures. OUTCOMES: Studies were included and tabulated if they reported prosthesis outcomes in patients who received a neophallus as part of a gender-affirming procedure. RESULTS: 23 journal articles met inclusion criteria from 434 references identified. All selected articles were either retrospective or case series/reports. A total of 1,056 patients underwent phalloplasty, and 792 received a penile prosthesis. Most (83.6%) of the prostheses were inflatable, whereas 16.4% were non-inflatable. The number of cylinders used for each prosthesis was 61.0% single-cylinder and 39.0% double-cylinder. The mean follow-up duration was 3.0 years. Of patients who received a prosthesis, 36.2% reported a prosthesis complication; at follow-up 60.0% of patients had their original implant present, and 83.9% reported achieving penetration. CLINICAL IMPLICATIONS: Prosthesis implantation in gender-affirming operations poses significant risk of complication, but it is still a reasonable and useful method to achieve rigidity necessary for sexual intercourse. STRENGTH & LIMITATION: This is the first study to aggregate all reported penile prosthesis characteristics and outcomes in trans masculine patients. This study was significantly limited by inconsistent reporting of demographics, sensation, urinary health, patient satisfaction, and penetrative sex. The lack of comparative studies precluded any meaningful meta-analytical comparison. CONCLUSIONS: There is a great need for a prosthesis designed to meet the specific needs of the trans masculine patient after phalloplasty. Standardized methods of reporting implant outcomes including sexual function, sensation, and patient satisfaction should be refined for future studies. This study can assist patients and surgeons about the risks and benefits of this procedure. Rooker SA, Vyas KS, DiFilippo EC, et al.

BACKGROUND: The Goldilocks mastectomy procedure involves local contouring of completely autologous breast tissue created by preserving and de-epithelializing the residual mastectomy flaps. The purpose of this study was to provide outcomes data for 96-Goldilocks mastectomy procedures analyzing indications, complications, relevant comorbidities, and adjuvant cancer treatment impacting reconstructive and aesthetic outcomes. METHODS: Comprehensive review of every patient who underwent Goldilocks mastectomy from 2012 to 2018 included relevant medical and surgical comorbidities, as well as complication profiles. Aesthetic outcomes were also assessed in those with postoperative imaging available. RESULTS: A total of 53 patients (96 breasts) were included in this study. Bilateral cases consisted of 81.1% of the total cohort (n = 86 cases), and 18.9% (n = 10 cases) were unilateral procedures. Mean age at the time of reconstruction was 55.8 (33-77) years. Mean body mass index (BMI) at the time of reconstruction was 33.7 (19.2-54.6). The overall complication rate was 9.38% (seroma = 2, hematoma = 1, cellulitis = 2, wound dehiscence = 3, and operating room take back = 1). CONCLUSIONS: Goldilocks breast reconstruction is a safe, effective option in patients with higher than average BMI or excess local breast tissue, or in patients meeting these criteria preferring a single-stage reconstruction. This study qualifies its use in patients with higher than average risk factors for more extensive reconstructive modalities.

BACKGROUND: Acquired defects of the cranium represent a reconstructive challenge in patients with calvarial bone loss due to trauma, infection, neoplasia, congenital malformations, or other etiologies. The objective of this study was to compare postoperative rates of infection, local complications, and allograft failures following cranioplasty reconstruction using titanium mesh (Ti), polymethyl methacrylate (PMMA), polyether ether ketone (PEEK), and Norian implants in adult patients. METHODS: This constitutes the first systematic review of available literature on 4 different methods of alloplastic cranioplasty reconstruction, including Ti, PMMA, PEEK, and Norian implants, using the Newcastle-Ottawa Quality Assessment Scale guidelines for article identification, screening, eligibility, and inclusion. Electronic literature search included Ovid MEDLINE/PubMed, EMBASE, Scopus, Google Scholar, and Cochrane Database. Pearson exact test was utilized at P < 0.05 level of significance (J.M.P. v11 Statistical Software). RESULTS: A total of 53 studies and 3591 patients (mean age, 40.1 years) were included (Ti = 1429, PMMA = 1459, PEEK = 221, Norian = 482). Polymethyl methacrylate implants were associated with a significantly higher infection rate (7.95%, P = 0.0266) compared with all other implant types (6.05%). Polyether ether ketone implants were associated with a significantly higher local complication rate (17.19%, P = 0.0307, compared with 12.23% in all others) and the highest ultimate graft failure rate (8.60%, P = 0.0450) compared with all other implant types (5.52%). CONCLUSIONS: This study qualifies as a preliminary analysis addressing the knowledge gap in rates of infection, local surgical complication, and graft failure in alloplastic cranioplasty reconstruction with different implant types in the adult population. Longer-term randomized trials are warranted to validate associations found in this study.

BACKGROUND: With the demand for stem cells in regenerative medicine, new methods of isolating stem cells are highly sought. Adipose tissue is a readily available and non-controversial source of multipotent stem cells that carries a low risk for potential donors. However, elevated donor body mass index has been associated with an altered cellular microenvironment and thus has implications for stem cell efficacy in recipients. This review explored the literature on adipose-derived stem cells (ASCs) and the effect of donor obesity on cellular function. METHODS: A review of published articles on obesity and ASCs was conducted with the PubMed database and the following search terms: obesity, overweight, adipose-derived stem cells and ASCs. Two investigators screened and reviewed the relevant abstracts. RESULTS: There is agreement on reduced ASC function in response to obesity in terms of angiogenic differentiation, proliferation, migration, viability, and an altered and inflammatory transcriptome. Osteogenic differentiation and cell yield do not show reasonable agreement. Weight loss partially rescues some of the aforementioned features. CONCLUSIONS: Generally, obesity reduces ASC qualities and may have an effect on the therapeutic value of ASCs. Because weight loss and some biomolecules have been shown to rescue these qualities, further research should be conducted on methods to return obese-derived ASCs to baseline.

BACKGROUND: The purpose of this study is to describe our experience and outcomes in oncoplastic pelvic reconstruction for patients who underwent either vertical rectus abdominis musculocutaneous (VRAM) or omental flap following abdominoperineal resection (APR) at a single tertiary care institution. METHODS: All patients who underwent pelvic reconstruction following APR with either VRAM or omental flaps from January 1992 to January 2017 were retrospectively reviewed. Patient demographics and relevant comorbidities including chemotherapy and radiation therapy data were collected and analyzed. In addition, margin status at the time of oncologic resection was analyzed. Flap-specific data were collected for each approach. Oncologic data collected included cancer type, stage at time of APR, and rate of tumor recurrence within the flap. RESULTS: A total of 562 patients were identified who underwent pelvic reconstruction with either VRAM or omental pedicle flaps. Of these, 274 (48.8%) underwent VRAM reconstruction and 288 (51.2%) underwent omental flap reconstruction. All margins were negative at time of cancer ablation surgery. Complications data included: seroma (VRAM = 2 [0.36%]; omentum = 32 [5.69%], p < 0.0001), wound dehiscence (VRAM = 31 [5.52%]; omentum = 17 [3.02%], p = 0.022), abscess (VRAM = 4 [0.71%]; omentum = 27 [4.8%], p < 0.0001), cellulitis (VRAM = 2 [0.36%]; omentum = 10 [1.78%], p = 0.025). Statistical comparison of tumor recurrence between these two reconstructive approaches showed a significantly higher recurrence rate in omental flaps compared with VRAM flaps (p = 0.000127). CONCLUSION: The results of this study suggest a significantly higher tumor recurrence rate in omental flap pelvic reconstruction compared with VRAM flaps. This knowledge has the potential to influence surgical planning and flap selection in pelvic reconstruction.

BACKGROUND: Dendritic cells (DCs) are bone marrow-derived, professional antigen-presenting cells with tolerogenic function. The ability of DCs to regulate alloantigen-specific T cell responses and to promote tolerance has aligned them ideally for a role in vascularized composite allotransplantation (VCA). In this study, we summarize the current evidence for DC therapies for tolerance induction to alleviate the requirement for chronic immunosuppression. METHOD: A comprehensive and structured review of manuscripts published on VCA was performed using the MEDLINE and PubMed databases. All eligible studies published from the year 2000 to 2017 were included in the final results. RESULT: Nineteen original preclinical and clinical studies that employed cell therapy for VCA were included in this review. In vivo DC therapy was found to direct the alloimmune response toward either transplant rejection or tolerance in VCA models. While injection of mature DCs rapidly increases T-cell activity in humans and promotes transplant rejection, the injection of immature DCs acts as an immunosuppressant and inhibits T-cell activity. In addition to immature DCs, mesenchymal stem cells were also found to have a positive effect on allotransplantation of solid organs and bone marrow via cytokine expression which decreases the alloreactive effector lymphocytes and increases CD4+/CD25+/FoxP3 Tregs. Despite the promising findings, the efficacy of cell-based therapies varies greatly across studies, partly due to different methods of cell isolation and purification techniques, source, route and timing of administration, and combination immunosuppressive therapy. CONCLUSION: Additional research is needed to evaluate the efficacy and safety of DC and other cell-based therapeutic measures in human allotransplant recipients. Future direction will focus on the development of novel methods to reduce immunosuppression and develop more individualized management, as well as the clinical application of basic research in the mechanisms of immunologic tolerance.

BACKGROUND: Telemedicine, the use of information technology and telecommunication to provide healthcare at a distance, is a burgeoning field with applications throughout medicine. Given the visual nature of plastic surgery and dermatology, telemedicine has a myriad of potential applications within the field. METHODS: A comprehensive literature review of articles published on telemedicine since January 2010 was performed. Articles were selected for their relevance to plastic and reconstructive surgery and dermatology, and then reviewed for their discussion of the applications, benefits, and limitations of telemedicine in practice. RESULTS: A total of 3119 articles were identified in the initial query. Twenty-three articles met the inclusion criteria in plastic surgery (7 wound management, 5 burn management, 5 trauma, 4 free flap care, 2 in cleft lip/palate repair). Twenty-three (100%) reported a benefit of telemedicine often related to improved postoperative monitoring, increased access to expertise in rural settings, and cost savings, either predicted or actualized. Eight (35%) reported limitations and barriers to the application of telemedicine, including overdiagnosis and dependence on functional telecommunication systems. Sixty-six articles focused on telemedicine in dermatology and also demonstrated significant promise. CONCLUSIONS: Telemedicine holds special promise in increasing the efficiency of postoperative care for microsurgical procedures, improving care coordination and management of burn wounds, facilitating interprofessional collaboration across time and space, eliminating a significant number of unnecessary referrals, and connecting patients located far from major medical centers with professional expertise without impinging on-and in some cases improving-the quality or accuracy of care provided. Teledermatology consultation was found to be safe and has a comparable or superior efficacy to the traditional in-patient consultation. The system was consistently rated as convenient and easy to use by patients, referring physicians, and consulting dermatologists. Teledermatology has also been used as an educational tool for patients. A significant number of studies detailed strategies to improve the current state of teledermatology, either by implementing new programs or improving technologies. Telemedicine use is widespread among plastic surgeons and is enabling the spread of expertise beyond major medical centers. Further research is needed to conclusively demonstrate benefit in routine clinical care.

Purpose Penile replantation is an uncommonly performed procedure, which can alleviate physical and psychosocial sequelae of penile amputation. This study critically appraises the current literature on penile replantation. Methods A comprehensive literature search of the Medline, PubMed, and Google Scholar databases was conducted with multiple search terms related to penile replantation. Data on outcomes, complications, and patient satisfaction were collected. Results A total of 74 articles met inclusion criteria. One hundred and six patients underwent penile replantation, but outcome, complication, and satisfaction data were not standardized across all patients. Penile amputation most often resulted from self-mutilation or trauma. The majority were complete amputations (74.8%). Full sensation was maintained in 68.4% of patients. Most reported adequate urinary function (97.4%) and normal erection (77.5%). Skin necrosis (54.8%) and venous congestion (20.2%) were the most common complications. Urethral stricture (11.0%) and fistula (6.6%) were common urethral complications. Most (91.6%) patients reported overall satisfaction although there was a lack of patient-reported outcomes. Multivariate analysis suggested that complete amputation (ß = 3.15, 95% CI 0.41-5.89, p = 0.024), anastomosis of the superficial dorsal artery (ß = 9.88, 95% CI 0.74-19.02, p = 0.034), and increasing number of nerves coapted (ß = 1.75, 95% CI 0.11-3.38, p = 0.036) were associated with favorable sexual, urinary, and sensation outcomes. Increasing number of vessels anastomosed (ß = -3.74, 95% CI -7.15 to -0.32, p = 0.032) was associated with unfavorable outcomes. Conclusion Although penile replantation is associated with complications, it has a high rate of satisfaction and efficacy. Coaptation of multiple nerves and anastomosis of the superficial dorsal artery should be completed.

Wounds are dynamic environments in which dead tissue, exudate, and the bacterial bioburden interact in a complex manner among themselves and with the tissue of the host. Bacteria organize into biofilms, reducing their susceptibility to elimination by the host immune response and antimicrobials. Early detection of biofilms in wounds is crucial to successful chronic wound management; and although many techniques have developed to identify planktonic counterparts in viable wounds, few have been able to quickly and accurately identify bacterial biofilms. Future studies are needed to find means of identifying and monitoring biofilm colonization at the bedside to permit timely initiation of treatment. In this review, we examine some promising new technologies that hope to identify and quantify the process of biofilm formation in chronic wounds.

Fat grafting has become a widely accepted modality of soft tissue restoration and has found applications in many areas of aesthetic and reconstructive plastic surgery. Numerous claims have been made regarding the regenerative effects of fat grafting on the recipient bed. The purpose of this paper is to survey the available literature to answer the question of whether fat grafting has a positive effect on the surrounding tissues. It has been convincingly demonstrated that fat grafts contain viable adipose-derived stem cells (ASCs). The fate of these cells is determined by the microenvironment of the recipient bed, but animal studies have shown that a large fraction of ASCs survive engraftment. Numerous clinical studies have demonstrated the positive effects of fat grafting on recipient tissues. Improvement in validated scar scores as well as scar stiffness measurements have been documented after fat grafting of burn scars. Fat grafting has also been convincingly demonstrated to improve the quality of irradiated tissues, as measured by validated clinical scales and staged histology. It is ultimately unclear whether ASCs are responsible for these effects, but the circumstantial evidence is weighty. Fat grafting is effective for volumizing and improving skin quality in the setting of radiation, burns, and other scars. The observed effects are likely due to ASCs, but the evidence does not support the routine use of ASC-enriched fat grafts.

PURPOSE: The management of occult tumor involvement of the nipple during total skin-sparing mastectomy (TSSM) and immediate reconstruction is not well addressed in the literature. We reviewed our experience with positive nipple core biopsies, comparing outcomes of different management options. METHODS: Mastectomy and implant/expander reconstructions over a 5-year period were reviewed. Patient characteristics, type of mastectomy, and complications were analyzed. Patients were grouped by type of mastectomy/immediate reconstruction and delayed reconstruction to compare outcomes. Positive intraoperative core nipple biopsy cases formed a subset of the TSSM group. RESULTS: Forty-four of 240 (18%) cases were TSSMs performed through inferolateral incisions. All were reconstructed immediately, 24 with tissue expanders and 20 with implants. Major complications (necrosis, infection, seroma) were significantly lower than for skin-sparing mastectomies, but higher than delayed reconstruction. One case of full thickness nipple necrosis occurred. Seven of the TSSM group had positive core nipple biopsies (16%). Three of these patients underwent nipple excision and tissue expander placement at the initial surgery, of which 2 developed subsequent mastectomy skin flap necrosis requiring explantation. A third patient underwent staged nipple excision without complication. The remaining 3 patients underwent delayed nipple resection at the time of tissue expander replacement without complication. Pathology in the nipple core was invasive ductal carcinoma and ductal carcinoma in situ. No TSSM patients have developed local recurrence at follow-up. CONCLUSIONS: Concurrent excision of the nipple and an inferolateral incision increase the incidence of skin flap necrosis. Delaying nipple excision may prove to be a safer option.
