ABSTRACT
INTRODUCTION: Thrombocytosis, defined as a platelet count >400,000, has been implicated as a risk factor in free flap failure. Despite proposed mechanisms of pedicle thrombosis, recent studies have suggested that thrombocytosis has no effect on free tissue transfer viability. Risk factors that may compromise successful free tissue transfer should be understood and elucidated, with particular attention to thrombocytosis and its conflicting evidence in the literature. We hypothesize that thrombocytosis has no bearing on free flap success or the rates of pedicle thrombosis. METHODS: Our institution performed a retrospective chart review on all patients who underwent free flap reconstruction over the past 6 years. Patient demographics, medical history, type and location of free tissue transfer, preoperative platelets, postoperative platelets, and flap outcomes and complications (wound dehiscence, infection, hematoma, seroma, and need for blood transfusion) were recorded. Independent t test, Mann-Whitney U tests, χ2 test, and Fisher exact tests were used to determine P values to compare flap outcomes in patients with thrombocytosis (platelet count >400,000) and those with platelet counts less than 400,000. RESULTS: In our 502-patient cohort, 71 were found to have a platelet count >400,000 (35 preoperatively and 36 postoperatively) and 431 patients had platelet counts <400,000. There were 42 reconstructive failures (flap success rate of 91.6%) and 111 returns to the operating room (OR). For patients with postoperative thrombocytosis, 24 flaps returned to the OR (44.4%), whereas in patients without thrombocytosis, 87 flaps returned to the OR (19.4%; P < 0.001). In patients with postoperative thrombocytosis, 10 OR returns were due to pedicle venous thrombosis (18.5%), in comparison to 10 returns for venous thrombosis in those with normal platelets (2.2%; P < 0.001). There was a small difference in free flap success rates between those with postoperative thrombocytosis and normal platelets, 88.7% versus 92.11%; however, this was not statistically significant ( P = 0.71). The thrombocytosis group had a higher incidence of overall postoperative complications ( P = 0.002). CONCLUSIONS: Thrombocytosis has historically been cited as a risk factor for free flap reconstruction failure with recent conflicting evidence in the literature. In patients with postoperative thrombocytosis, we found an increased risk of venous thrombosis; however, this did not result in increased flap failure. There was an increase in postoperative complications, which corresponds with National Surgical Quality Improvement Program data reported in the literature. We suspect that thrombocytosis is not a harbinger of free flap failure but rather a marker for overall inflammation, which may confer a higher rate of venous thrombosis requiring reoperation and postoperative complications.

Background: Treating facial aging with CO2 lasering or microneedling are cornerstones of facial rejuvenation. Skin rejuvenation utilizing thermal and mechanical treatments have historically been considered too injurious to be combined at a single setting. Autologous nanofat has been shown to deliver wound healing properties. We investigated the safety and efficacy of co-terminus CO2 lasering and microneedling to resolve fine lines and rhytids in facial skin with addition of autologous nanofat to aid in recovery. Objectives: Combination treatments may result in better results with faster recovery. We investigated the safety and efficacy of co-terminus CO2 lasering and microneedling to resolve fine lines and rhytids in facial skin with addition of autologous nanofat to aid in recovery. Methods: Twenty-three patients underwent facial treatment with CO2 lasering followed by microneedling and application of autologous nanofat (LaMiNa). One volunteer patient had tissue biopsies of treatment areas to demonstrate histologic tissue level changes. Results: All patients verbally reported no pain (Numerical Rating System 0-10) following procedure and had rapid recovery within an average of 5 days. Pathology results demonstrated that CO2 and microneedling had persistent epidermal disruption and perineural inflammation at 4 days, while the introduction of autologous nanofat at the time of CO2 and microneedling resulted in full recovery of epidermis and resolution of perineural inflammation. Conclusions: Triple therapy (LaMiNa) with thermal CO2 remodeling and mechanical microneedling penetration have accelerated and pain-free recovery with the addition of autologous nanofat. Histologic analysis reveals that epidermal recovery is accelerated and perineural inflammation is reduced with the addition of autologous nanofat following skin remodeling from combined CO2 and microneedling.
ABSTRACT
BACKGROUND: With the increasing demand for body contouring procedures in the United States over the past 2 decades, more surgeons with diverse specialty training are performing these procedures. However, little is known regarding the comparative outcomes of these patients. OBJECTIVES: The purpose of this study was to compare outcomes of body contouring procedures based on the specialty training of the surgeon. METHODS: Data from the American College of Surgeons National Surgical Quality Improvement Program (2005-2015) were reviewed for all body contouring procedures. Patients were stratified by surgeon training (plastic surgery [PS] vs general surgery [GS]). Descriptive statistics and regression analyses were used to evaluate differences in outcomes. RESULTS: A total of 11,658 patients were included; 9502 PS cases and 2156 GS cases. Most were women (90.4%), aged 40 to 59 (52.7%) and white (79.5%). Compared with PS patients, GS patients were more likely to be obese (61.4% vs 40.6%), smokers (13.6% vs 9.8%), and with ASA classification ≥3 (35.3% vs 18.6%) (all P < 0.001). Abdominal contouring procedures were the most common (76%) cases. Multivariate regression revealed that compared with PS cases, those performed by GS practitioners were associated with increased wound and infectious complications (adjusted odds ratio [aOR], 1.81; 95% confidence interval [CI], 1.44-2.27), reoperation (aOR, 1.85; 95% CI, 1.31-2.62), and predicted mean length of stay (1.12 days; 95% CI, 0.64-1.60 days). CONCLUSIONS: The variable outcomes in body contouring procedures performed by PS compared with GS practitioners may imply procedural-algorithmic differences between the subspecialties, leading to the noted outcome differential.

Among U.S. youth (N = 14,041), perceived (odds ratio [OR]adj. = 1.45, 95% confidence interval [CI]: 1.18-1.72) and actual overweight (ORadj. = 1.31, 95% CI: 1.07-1.60) were associated with suicide attempts in analyses controlling for demographic characteristics and potential confounders. There is a need to better understand associations between perceived and actual overweight and risk for suicide attempts and to develop appropriate strategies for prevention.
