A Prospective, Multicenter Trial on the Efficacy and Safety of Poly-L-Lactic Acid for the Treatment of Contour Deformities of the Buttock Regions.

BACKGROUND: There is a significant emphasis on minimally invasive whole-body rejuvenation throughout the world. Recently, gluteal aesthetics have become an increasingly common patient concern. Although the application of poly-L-lactic acid (PLLA) to the face is already well known, there are relatively fewer publications on its use in other corporeal regions. This study aims to extend previous findings by evaluating the efficacy and safety of PLLA in the treatment of contour (including lifting) deformities of the buttock region. METHODS: This was a prospective, multicenter (3 sites), single cohort, open-label clinical trial. Thirty female subjects were treated with PLLA in the bilateral buttocks, with three treatment sessions, each spaced one month apart and followed for six months after completion of the treatment regimen. At each visit, various safety and clinical efficacy parameters were collected, these included: Global Assessment of Improvement Scale (GAIS), subject satisfaction, skin hydration, elasticity, scaliness, roughness, and 3-dimensional imagery. RESULTS: Six months following the last treatment, 84.00% of patients were rated as having “improved” or more on the physician assessed GAIS, accompanied by a 96.00% patient satisfaction rate. Approximately three vials of PLLA, per buttock and treatment were used. There were no serious adverse events throughout the duration of the trial, nor adverse events related to the investigational device. The most common subject-reported adverse events included pain during treatment (Mean: 70.97%) and bruising (Mean: 28.80%). Objective improvements were persistent after treatment in measurements of skin elasticity (improved 63.5% - 82.5% from weeks 16-32), hydration (increased ~11 Corneometer® units by week 16), roughness (decreased 36.95% at week 32), and scaliness (desquamation; decreased 60.41% at week 32). CONCLUSIONS: PLLA is safe and effective for the indication of buttock contouring and improving parameters of skin health. PLLA can provide long-lasting effects with a high level of patient and physician satisfaction. J Drugs Dermatol. 2022;21(3):304-308. doi:10.36849/JDD.5924.

Analysis of Utility Assessment Scores to Objectify the Health Burden Caused by Breast Conservation Therapy.

BACKGROUND: Lumpectomy followed by radiation, known as breast conservation therapy (BCT), is a viable surgical treatment option for early-stage breast cancer. However, the current literature suggests that patients prefer mastectomy over BCT, likely due to the wide variety of postmastectomy reconstructive options. Our aim is to investigate the objective health burden of living with BCT to help surgeons gain a better understanding of patient treatment preferences. METHODS: Three validated health state utility tools were used to objectify the burden of living with post-BCT results: visual analogue scale (VAS), time trade-off (TTO), and standard gamble (SG). A prospective sample of the general population and medical students were recruited, and their responses analyzed to attain these scores. RESULTS: Utility scores for living with BCT are VAS 0.81 ± 0.19, TTO 0.93 ± 0.10, and SG 0.92 ± 0.14. The TTO and SG suggest a willingness to trade 2.5 years of life years and an 8% chance of death undergoing reconstructive procedures to correct a BCT defect, respectively. Age, gender, race, education, and income were not statistically significant independent predictors for higher or lower utility scores. CONCLUSION: The impact of the health burden of BCT was ascertained using validated objective numeric utility scores. These indices demonstrate a willingness to trade less life years to undergo correction of a BCT defect than reconstruction following unilateral mastectomy. They can provide surgeons with the best objective understanding of patient preferences for shared decision-making in the management of breast cancer.

HISTORIQUE: La lumpectomie suivie d'une radiothérapie, ou conservation mammaire (CM), est un traitement chirurgical viable du cancer du sein précoce. Selon les publications, les patients préfèrent toutefois la mastectomie à la CM, probablement en raison du large éventail de possibilités de reconstructions après la mastectomie. Les chercheurs visent à explorer le fardeau objectif d'une vie avec une CM pour la santé, afin d'aider les chirurgiens à mieux comprendre les préférences des patientes en matière de traitement. MÉTHODOLOGIE: Les chercheurs ont utilisé trois outils utilitaires validés sur l'état de santé pour objectiver le fardeau de la vie après une CM : l'échelle visuelle analogique (ÉVA), l'arbitrage temporel (AT) et le pari standard (PS). Ils ont recruté un échantillon prospectif de la population générale et d'étudiants en médecine et ont analysé leurs réponses pour obtenir les scores. RÉSULTATS: Les scores d'utilité d'une vie avec une CM s'établissent comme suit : ÉVA 0,81 ± 0,19, AT 0,93 ± 0,10 et PS 0,92 ± 0,14. L'AT et le PS indiquent respectivement la volonté de perdre 2,5 années de vie et d'accroître le risque de décès de 8 % pendant les interventions de reconstruction pour corriger une anomalie de CM. L'âge, le genre, la race, l'instruction et le revenu n'étaient pas des prédicteurs indépendants statistiquement significatifs des scores d'utilité plus élevés ou plus faibles. CONCLUSION: Les chercheurs ont évalué les répercussions du fardeau de la CM sur la santé au moyen de scores d'utilité numériques validés. Ces indices démontrent la volonté de réduire le nombre d'années de vie pour corriger une anomalie de la CM plutôt qu'une reconstruction après une mastectomie unilatérale. Ils peuvent aider les chirurgiens à mieux comprendre les préférences des patientes pour parvenir à une décision commune en matière de prise en charge du cancer du sein.

Utility outcome assessment of pes planus deformity.

BACKGROUND: Despite being a common condition, there are no objective measures in the literature to reflect the burden of pes planus on affected individuals. Our primary objective was to evaluate this burden by recruiting a sample from the general population using validated utility outcome measures. METHODS: Participants were recruited online and filled a questionnaire to help measure the health burden of pes planus. Three recognized utility outcome scores were used to compare the health burden of monocular blindness, binocular blindness, and pes planus. These included the standard gamble (SG), time trade-off (TTO), and visual analogue score (VAS). Paired t test, independent t test, and linear regression were used for statistical analysis. RESULTS: Ninety-two participants were included in the final analysis. The utility outcome scores (VAS, TTO, SG) for pes planus were 73±17, 0.90±0.08, and 0.88±0.12, respectively. The linear regression analysis showed that age was inversely proportional to the time trade-off. However, race, educational level, and income were not significant predictors of utility outcome score for pes planus. CONCLUSIONS: This study shows that the perceived burden of living with pes planus is comparable to living with some debilitating conditions. Our participants were willing to sacrifice 3.6 years of life, and have a procedure with a theoretical 12% mortality risk to attain perfect health.

Prospective, Double-Blind Evaluation of Umbilicoplasty Techniques Using Conventional and Crowdsourcing Methods.

BACKGROUND: Umbilical reconstruction is an important component of deep inferior epigastric perforator (DIEP) flap breast reconstruction. This study evaluated the aesthetics of three different umbilical reconstruction techniques during DIEP flap breast reconstruction. METHODS: From January to April of 2013, a total of 29 consecutive patients undergoing DIEP flap breast reconstruction were randomized intraoperatively to receive one of three umbilicoplasty types: a diamond, an oval, or an inverted V incision. Independent plastic surgeons and members of the general public, identified using an online "crowdsourcing" platform, evaluated aesthetic outcomes in a blinded fashion. Reviewers were shown postoperative photographs of the umbilicus of all patients and a four-point Likert scale was used to rate the new umbilicus on the size, scar formation, shape, localization, and overall appearance. RESULTS: Results for the focus group of independent plastic surgeons and 377 members of the public were retrieved (n = 391). A total of 10 patients (34.5 percent) were randomized into having the diamond incision, 10 (34.5 percent) had the oval incision, and nine (31.0 percent) had the inverted V incision. Patients were well matched in terms of overall characteristics. The general public demonstrated a significant preference for the oval incision in all five parameters. There was no preference identified among surgeons. CONCLUSION: This study provides evidence that a sample of the U.S. general public prefers the aesthetics of the oval umbilicoplasty incision, which contrasted with the lack of preference identified within this focus group of plastic surgeons. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.

Impact of Living With Scoliosis: A utility Outcome Score Assessment.

STUDY DESIGN: Survey. OBJECTIVE: The aim of this study was to objectify the burden of adolescent idiopathic scoliosis (AIS) to better advocate for scoliosis care in the future. SUMMARY OF BACKGROUND DATA: AIS is a common spinal deformity that can affect individuals on many levels. Patients with big curves usually seek medical advice for surgical correction of their deformity. METHODS: Participants completed an online questionnaire to help measure the health burden of AIS. Three utility outcome measures were then calculated. These included the visual analog scale, time trade off, and standard gamble. Student t test and linear regression were used for statistical analysis. RESULTS: One hundred and ten participants were included in the analysis. The mean visual analog scale, time trade off, and standard gamble scores for AIS were 0.77 ±â€Š0.16, 0.90 ±â€Š0.11, and 0.91 ±â€Š0.13, respectively. Factors such as age, sex, income, and level of education were dependent predictors of utility scores for AIS. CONCLUSION: Our participants demonstrated a significant perceived burden of AIS. If faced with AIS, participants were willing to sacrifice 3.6 years of their lives and undergo a procedure with 9% mortality rate to gain perfect health. Such findings can guide future allocation of resources for better scoliosis care and management. LEVEL OF EVIDENCE: 4.

Bilateral Hallux Valgus: A Utility Outcome Score Assessment.

Hallux valgus is the most common forefoot problem in adults. Although it can cause considerable disability and affect the quality of life of those affected, many patients seek medical attention because of cosmetic concerns. Our aim was to objectively measure the perceived health burden of living with bilateral hallux valgus. Previously validated utility outcome measures, including the visual analog scale, time trade-off, and standard gamble tests, were used to quantify the health burden for single-eye blindness, double-eye blindness, and bilateral hallux valgus in 103 healthy subjects using an online survey. The Student t test and linear regression analysis were used for statistical analysis. The mean visual analog scale, time trade-off, and standard gamble scores for bilateral hallux valgus were 0.86 ± 1.6, 0.95 ± 0.5, and 0.95 ± 0.14, respectively. These were significantly greater than the utility scores for single-eye and double-eye blindness (p < .05). Age, gender, race, income, and education were not statistically significant independent predictors of the utility scores for hallux valgus. In conclusion, we have objectively demonstrated the effect of living with bilateral hallux valgus deformities. Our sample population reported being willing to undergo a procedure with a 5% mortality rate and sacrifice 1.8 years of life to attain perfect health and avoid the bilateral hallux valgus health state. Our findings will guide us in counseling our patients and understanding how they perceive their foot deformity.

Mastopexy for breast ptosis: Utility outcomes of population preferences.

BACKGROUND: Breast ptosis can occur with aging, and after weight loss and breastfeeding. Mastopexy is a procedure used to modify the size, contour and elevation of sagging breasts without changing breast volume. To gain more knowledge on the health burden of living with breast ptosis requiring mastectomy, validated measures can be used to compare it with other health states. OBJECTIVE: To quantify the health state utility assessment of individuals living with breast ptosis who could benefit from a mastopexy procedure; and to determine whether utility scores vary according to participant demographics. METHODS: Utility assessments using a visual analogue scale (VAS), time trade-off (TTO) and standard gamble (SG) methods were used to obtain utility scores for breast ptosis, monocular blindness and binocular blindness from a sample of the general population and medical students. Linear regression and the Student's t test were used for statistical analysis; P<0.05 was considered to be statistically significant. RESULTS: Mean (± SD) measures for breast ptosis in the 107 volunteers (VAS: 0.80±0.14; TTO: 0.87±0.18; SG: 0.90±0.14) were significantly different (P<0.0001) from the corresponding measures for monocular blindness and binocular blindness. When compared with a sample of the general population, having a medical education demonstrated a statistically significant difference in being less likely to trade years of life and less likely to gamble risk of a procedure such as a mastopexy. Race and sex were not statistically significant independent predictors of risk acceptance. DISCUSSION: For the first time, the burden of living with breast ptosis requiring surgical intervention was determined using validated metrics (ie, VAS, TTO and SG). The health burden of living with breast ptosis was found to be comparable with that of breast hypertrophy, unilateral mastectomy, bilateral mastectomy, and cleft lip and palate. Furthermore, breast ptosis was considered to be closer to 'perfect health' than monocular blindness, binocular blindness, facial disfigurement requiring face transplantation surgery, unilateral facial paralysis and severe lower extremity lymphedema. CONCLUSIONS: Quantifying the health burden of living with breast ptosis requiring mastopexy indicated that is comparable with other breast-related conditions (breast hypertrophy and bilateral mastectomy). Numerical values have been assigned to this health state (VAS: 0.80±0.14; TTO: 0.87±0.18; and SG: 0.90±0.14), which can be used to form comparisons with the health burden of living with other disease states.

HISTORIQUE: La ptose mammaire découle du vieillissement, d'une perte de poids et de l'allaitement. La mastopexie est une intervention utilisée pour modifier la taille, le contour et l'élévation des seins affaissés sans en modifier le volume. Pour en savoir plus sur le fardeau d'une ptose mammaire exigeant une mastectomie sur la santé, on peut utiliser des mesures validées pour la comparer à d'autres états de santé. OBJECTIF: Quantifier l'évaluation utilitaire de l'état de santé des personnes qui présentent une ptose mammaire et qui profiteraient d'une mastopexie et déterminer si les scores d'utilité varient selon la démographie des participants. MÉTHODOLOGIE: Les chercheurs ont utilisé des évaluations utilitaires au moyen d'une échelle analogique visuelle (ÉAV), de l'arbitrage temporel (AT) et de la méthode du pari standard (PS) pour obtenir les scores d'utilité de la ptose mammaire, de la cécité monoculaire et de la cécité binoculaire d'un échantillon de la population générale et d'étudiants dans une profession médicale. La régression linéaire et le test t de Student ont été utilisés pour l'analyse statistique. P<0,05 était considéré comme statistiquement significatif. RÉSULTATS: Les mesures moyennes (± ÉT) de la ptose mammaire de 107 volontaires (ÉAV : 0,80±0,14, AT : 0,87±0,18, PS : 0,90±0,14) étaient statistiquement différentes (P<0,0001) des mesures correspondantes de cécité monoculaire et de cécité binoculaire. Par rapport à un échantillon en population, des connaissances médicales démontraient une différence statistiquement significative dans la moins grande susceptibilité à échanger des années de vie et à parier sur le risque d'une intervention comme la mastopexie. La race et le sexe n'étaient pas statistiquement significatifs, quels que soient les prédicteurs d'acceptation du risque. EXPOSÉ: Pour la première fois, le fardeau de la ptose mammaire exigeant une intervention chirurgicale a été établi au moyen de mesures validées (ÉAV, AT et PS). Ainsi, le fardeau de la ptose mammaire sur la santé était comparable à celui de l'hypertrophie mammaire, de la mastectomie unilatérale, de la mastectomie bilatérale et de la fente labiopalatine. Par ailleurs, la ptose mammaire était considérée comme plus près de la « santé parfaite ¼ que la cécité monoculaire, la cécité binoculaire, la défiguration exigeant une transplantation faciale, une paralysie faciale unilatérale et un lymphœdème des membres inférieurs. CONCLUSIONS: La quantification du fardeau de la ptose mammaire exigeant une mastopexie sur la santé est comparable à d'autres problèmes mammaires (hypertrophie mammaire et mastectomie bilatérale). Des valeurs numériques ont été attribuées à cet état de santé (ÉAV : 0,80±0,14, AT : 0,87±0,18 et PS : 0,90±0,14), et peuvent être utilisées pour former des comparaisons avec le fardeau d'autres états pathologiques sur la santé.

Nipple-areolar Complex Reconstruction following Postmastectomy Breast Reconstruction: A Comparative Utility Assessment Study.

BACKGROUND: Nipple-areola complex (NAC) reconstruction occurs toward the final stage of breast reconstruction; however, not all women follow through with these procedures. The goal of this study was to determine the impact of the health state burden of living with a reconstructed breast before NAC reconstruction. METHODS: A sample of the population and medical students at McGill University were recruited to establish the utility scores [visual analog scale (VAS), time trade-off (TTO), and standard gamble (SG)] of living with an NAC deformity. Utility scores for monocular and binocular blindness were determined for validation and comparison. Linear regression and Student's t test were used for statistical analysis, and significance was set at P < 0.05. RESULTS: There were 103 prospective volunteers included. Utility scores (VAS, TTO, and SG) for NAC deformity were 0.84 ± 0.18, 0.92 ± 0.11, and 0.92 ± 0.11, respectively. Age, gender, and ethnicity were not statistically significant independent predictors of utility scores. Income thresholds of <$10,000 and >$10,000 revealed a statistically significant difference for VAS (P = 0.049) and SG (P = 0.015). Linear regression analysis showed that medical education was directly proportional to the SG and TTO scores (P < 0.05). CONCLUSIONS: The absence of NAC in a reconstructed breast can be objectively assessed using utility scores (VAS, 0.84 ± 0.18; TTO, 0.92 ± 0.11; SG, 0.92 ± 0.11). In comparison to prior reported conditions, the quality of life in patients choosing to undergo NAC reconstruction is similar to that of persons living with a nasal deformity or an aging neck requiring rejuvenation.

The utility of outcome studies in plastic surgery.

SUMMARY: Outcome studies help provide the evidence-based science rationalizing treatment end results that factor the experience of patients and the impact on society. They improve the recognition of the shortcoming in clinical practice and provide the foundation for the development of gold standard care. With such evidence, health care practitioners can develop evidence-based justification for treatments and offer patients with superior informed consent for their treatment options. Furthermore, health care and insurance agencies can recognize improved cost-benefit options in the purpose of disease prevention and alleviation of its impact on the patient and society. Health care outcomes are ultimately measured by the treatment of disease, the reduction of symptoms, the normalization of laboratory results and physical measures, saving a life, and patient satisfaction. In this review, we outline the tools available to measure outcomes in plastic surgery and subsequently allow the objective measurements of plastic surgical conditions. Six major outcome categories are discussed: (1) functional measures; (2) preference-based measures and utility outcome scores; (3) patient satisfaction; (4) health outcomes and time; (5) other tools: patient-reported outcome measurement information system, BREAST-Q, and Tracking Operations and Outcomes for Plastic Surgeons; and (6) cost-effectiveness analysis. We use breast hypertrophy requiring breast reduction as an example throughout this review as a representative plastic surgical condition with multiple treatments available.

Patient selection optimization following combined abdominal procedures: analysis of 4925 patients undergoing panniculectomy/abdominoplasty with or without concurrent hernia repair.

BACKGROUND: Massive weight loss following bariatric surgery causes unwanted excess skin and subcutaneous tissue. Intraoperative abdominal wall exposure during abdominal contouring surgery provides the possibility for concurrent ventral, umbilical, or inguinal hernia repair. The authors evaluated the incidence of postoperative complications following abdominal contouring surgery with or without concurrent hernia repair and the impact of surgical specialty. METHODS: Analysis of patients undergoing abdominal contouring surgery with or without concurrent hernia repair was performed using the American College of Surgeons National Surgical Quality Improvement Program from 2005 to 2011. The incidence of postoperative complications was determined. Logistic regression assessed influence of demographics and comorbidities on postoperative outcomes. Control group (body mass index > 27.5) and high-risk group (body mass index > 40) undergoing a hernia repair were also included for comparison. RESULTS: Among 4925 patients, 63.7 percent underwent abdominoplasty and/or panniculectomy only; 36.3 percent underwent a simultaneous hernia repair. The abdominal contouring surgery with simultaneous hernia repair group had a higher complication rate than the abdominal contouring surgery group (18.3 percent versus 9.8 percent, p < 0.001). Body mass index was associated with increased wound complications and major complications in both groups. Diabetes, smoking, chronic steroid use, and hypertension increased wound complications in the abdominal contouring surgery/hernia repair group. CONCLUSIONS: Patients undergoing hernia repair with abdominal contouring surgery may have higher postoperative complication rates than after abdominal contouring surgery alone. Hypertension, smoking, and chronic steroid use were predictors for negative outcomes. Furthermore, surgical specialty is associated with significantly different complication rates. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Population preferences of undergoing brachioplasty for arm laxity.

BACKGROUND: The number of patients requesting surgical procedures performed for brachioplasty and massive weight loss is increasing. The authors set out to quantify the health state utility outcome assessment of living with arm deformity requiring brachioplasty. METHODS: Utility assessments using the visual analog scale (VAS), time trade-off (TTO), and standard gamble (SG) were used to obtain utilities scores for arm deformity, monocular blindness, and binocular blindness from a sample of the general population and medical students. Linear regression and Student t test were used for statistical analysis. A P value less than 0.05 was deemed statistically significant. RESULTS: All the measures for arm deformity of the 107 volunteers (VAS, 0.80 ± 0.14; TTO, 0.91 ± 0.12; SG, 0.94 ± 0.10) were significantly different (P < 0.001) from the corresponding measures for monocular blindness and binocular blindness. When compared to the sample of the general population, having a medical education demonstrated a statistical significance of being less likely to trade years of life and less likely to gamble risk of death for a procedure such as a brachioplasty. Race and sex were not statistically significant independent predictors of risk acceptance. CONCLUSIONS: We have objectified the health state of living with upper arm deformity requiring brachioplasty. Utility outcome scores (VAS, 0.80 ± 0.14; TTO, 0.91 ± 0.12; SG, 0.94 ± 0.10) were comparable to living with health states such as aging neck needing rejuvenation, excess skin in the thighs necessitating thigh lift, and massive weight loss requiring panniculectomy based on previously reported studies.

The ideal nasolabial angle in rhinoplasty: a preference analysis of the general population.

BACKGROUND: In aesthetic rhinoplasty, the described ideal nasolabial angle ranges from 90 to 120 degrees, with variable anthropologic differences. The authors sought to verify the most aesthetic nasolabial angle as specifically perceived by a random prospective sample of the general population and determine whether age, sex, race, and education were independent associated predictors. METHODS: The authors prospectively recruited 98 random volunteers from the general population. They were asked to rank three different nasolabial angles for the female nose (100, 105, and 110 degrees) and the male nose (90, 100, and 105 degrees) as "most," "moderately," and "least aesthetic." Demographic data were used to determine correlations between aesthetic preferences. Pearson chi-square test and t test were used to determine statistical significance RESULTS: The most aesthetic female nasolabial angle was 104.9±4.0 degrees. The most aesthetic male nasolabial angle was 97.0±6.3 degrees. Male subjects, younger volunteers, Native Americans, and African Americans preferred more acute male nasolabial angles (90 degrees). Female subjects, volunteers older than 50 years, college graduates, those with a previous rhinoplasty, and Caucasian and Asian subjects preferred more obtuse male nasolabial angles. CONCLUSIONS: In the authors' sample of the general population, the ideal and most aesthetic nasolabial angle ranged from 100.9 to 108.9 degrees in the female nose and 90.7 to 103.3 degrees in the male nose. Age, sex, race, education, and having undergone a previous rhinoplasty were predictors of differences in the ideal male nasolabial angle but did not change preference of the female nasolabial angle.

Living with a unilateral mastectomy defect: a utility assessment and outcomes study.

BACKGROUND: The gold standard for the treatment of breast cancer includes mastectomy surgery. Our goal was to quantify the health state utility assessment of living with unilateral mastectomy. METHODS: The visual analogue scale (VAS), time trade-off (TTO), and standard gamble (SG) were used to obtain utilities for unilateral mastectomy, monocular blindness and binocular blindness from a prospective sample of the general population and medical students. RESULTS: All measures (VAS, TTO, SG) for unilateral mastectomy (0.75 SD 0.17, 0.87 SD 0.14, and 0.86 SD 0.18, respectively) of the 140 volunteers were significantly different from the corresponding scores for monocular (0.61 SD 0.18, 0.84 SD 0.17, and 0.84 SD 0.18, respectively) and binocular blindness (0.38 SD 0.17, 0.67 SD 0.24, and 0.69 SD 0.23, respectively). Age, gender, race, education, and income were not statistically significant independent predictors of utility scores. CONCLUSION: In a sample of the general population and medical students, utility assessments for living with unilateral mastectomy were comparable with those of living with bilateral mastectomy and severe breast hypertrophy. Our sample population, if faced living with unilateral mastectomy was willing to gamble a theoretical 14% chance of death and willing to trade 4.2 years of existing life-years.

The impact of living with severe lower extremity lymphedema: a utility outcomes score assessment.

BACKGROUND: Debilitating lower extremity lymphedema can be either congenital or acquired. Utility scores are an objective measure used in medicine to quantify degrees of impact on an individual's life. Using standardized utility outcome measures, we aimed to quantify the health state of living with severe unilateral lower extremity lymphedema. METHODS: A utility outcomes assessment using visual analog scale, time trade-off, and standard gamble was used for lower extremity lymphedema, monocular blindness, and binocular blindness from a sample of the general population and medical students. Average utility scores were compared using a paired t test. Linear regression was performed using age, race, and education as independent predictors. RESULTS: A total of 144 prospective participants were included. All measures [visual analog scale, time trade-off, and standard gamble; expressed as mean (SD)] for unilateral lower extremity lymphedema (0.50 ± 0.18, 0.76 ± 0.22, and 0.76 ± 0.21, respectively) were significantly different (P < 0.001) from the corresponding scores for monocular blindness (0.64 ± 0.18, 0.84 ± 0.16, and 0.83 ± 0.17, respectively) and binocular blindness (0.35 ± 0.17, 0.61 ± 0.28, and 0.62 ± 0.26, respectively). CONCLUSIONS: We found that a sample of the general population and medical students, if faced with severe lymphedema, is willing to theoretically trade 8.64 life-years and undergo a procedure with a 24% risk of mortality to restore limb appearance and function to normal. These findings provide a frame of reference regarding the meaning of a diagnosis of severe lower extremity lymphedema to a patient and will allow objective comparison with other health states.

The effects of Moufarrege total posterior pedicle reduction mammaplasty on breastfeeding: a review of 931 cases.

BACKGROUND: Since its original description in 1979, the Moufarrege total posterior pedicle reduction mammaplasty technique has proven to be a safe and reliable procedure providing aesthetic and functional enhancement. OBJECTIVES: To determine if the Moufarrege total posterior pedicle reduction mammaplasty affects successful breastfeeding. METHOD: Retrospective chart review was performed for patients operated on between 1981 and 1997, and a written questionnaire was given. Patients were asked about their ability to lactate and successfully breastfeed preoperatively and postoperatively. The t test and χ(2) test were used to compare means and categorical variables, respectively. Values were also compared with a sample of women (n = 2223) from the Quebec general population as collected by the Longitudinal Study of Child Development in Quebec (ELDEQ, 1998-2002). RESULTS: A total of 931 patients (all women) underwent reduction mammaplasty during the study period at Jewish General Hospital, Montreal, Quebec, Canada (H.S.) or Hopital Hotel-Dieu, Montreal, Quebec, Canada (E.B. and R.M). There was a 62% response rate to the questionnaire. There were no statistically significant differences in the percentage of women able to lactate postoperatively vs preoperatively (98% vs 100%, respectively; P = .2). The percentage of women able to successfully breastfeed for 4 and 6 months was also not statistically different when comparing postoperative vs preoperative ability (4 months: 33% vs 44 %, P = .13; 6 months: 29% vs 28%, P = .77). The sample of women from the Quebec population did not differ statistically from those undergoing the Moufarrege breast reduction in terms of successful breastfeeding for 1, 2, 3, and 4 months (59% vs 67%, 52% vs 47%, 42% vs 41%, and 40% vs 33%, respectively). CONCLUSIONS: The Moufarrege breast reduction technique is a reliable and safe procedure that does not seem to negatively affect the success of breastfeeding based on the results of our retrospective chart review and patient questionnaire. LEVEL OF EVIDENCE: 4.

Analysis of the National Surgical Quality Improvement Program database in 19,100 patients undergoing implant-based breast reconstruction: complication rates with acellular dermal matrix.

BACKGROUND: The use of acellular dermal matrices has become increasingly popular in immediate and delayed tissue expander/implant-based breast reconstruction. However, it is unclear whether their use is associated with increased postoperative complication rates. Using the American College of Surgeons National Surgical Quality Improvement Program database, the authors assessed baseline differences in demographics and comorbidities with and without acellular dermal matrix and determined whether postoperative complication rates varied. METHODS: Using the national surgical database (2005 to 2011), tissue expander/implant-based breast reconstruction cases were extracted using Current Procedural Terminology codes. Differences in preoperative demographics and comorbidities were assessed using chi-square and t test analysis using SPSS. The authors analyzed variations in complication rates and determined whether demographics and comorbidities affected outcomes using multivariate logistical analysis. A post hoc power study was calculated. RESULTS: Of 19,100 cases, 3301 involved acellular dermal matrix use. Overall complication rates were not statistically significant (acellular dermal matrix, 5.3 percent; non-acellular dermal matrix, 4.9 percent; p=0.396). Several risk factors were statistically significant associated factors of complications. Higher body mass index was associated with wound complications in both cohorts. In the non-acellular dermal matrix group, body mass index, smoking, and diabetes were associated with major complications, and radiotherapy and steroid use with minor complications. CONCLUSIONS: Acellular dermal matrix use did not appear to increase complication rates in tissue expander/implant-based breast reconstruction in this survey of a national surgical database. There was no significant difference in complication rates between the acellular dermal matrix and non-acellular dermal matrix groups. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Open reduction internal fixation poststernotomy mediastinitis.

Introduction. Mediastinitis has been reported to complicate 5% of sternotomy surgery. We have adopted an open reduction and rigid internal fixation (ORIF) approach during the conventional rescue surgery in the treatment of mediastinitis. Methods. A retrospective review was performed to compare the outcomes of patients that had an ORIF to correct postoperative mediastinitis following median sternotomy. These were compared with the outcome of the patients that did not undergo ORIF. Results. In the 5-year study period, we reviewed 35 mediastinitis patient charts. Postoperatively, the ORIF patient group remained in the Intensive Care Unit (ICU) and on a ventilator for a mean of 1.5 and 0.75 days, respectively. Patients treated without ORIF spent significantly more days in the ICU (mean of 7.5 days, P < 0.05) and on a ventilator (mean of 2.15 days, P = 0.1). Furthermore, it was found that none of the patients (0%) who underwent ORIF complained of any postoperative sternal instability or pain. Preoperatively, however, these rates were as high as 72%. Conclusions. In the select patient, ORIF can be a safe option in the management of mediastinitis, which we have shown to significantly decrease morbidity and mortality by providing anatomic reduction as well as physiologic stabilization. We have shown that ORIF will improve the quality of life of the patient by minimizing abnormal sternal mobility and pain and will also decrease inpatient costs by decreasing days spent in the ICU and ventilator dependence.

Complements and the wound healing cascade: an updated review.

Wound healing is a complex pathway of regulated reactions and cellular infiltrates. The mechanisms at play have been thoroughly studied but there is much still to learn. The health care system in the USA alone spends on average 9 billion dollars annually on treating of wounds. To help reduce patient morbidity and mortality related to abnormal or prolonged skin healing, an updated review and understanding of wound healing is essential. Recent works have helped shape the multistep process in wound healing and introduced various growth factors that can augment this process. The complement cascade has been shown to have a role in inflammation and has only recently been shown to augment wound healing. In this review, we have outlined the biology of wound healing and discussed the use of growth factors and the role of complements in this intricate pathway.

Complements c3 and c5 individually and in combination increase early wound strength in a rat model of experimental wound healing.

Background. Complements C3 and C5 have independently been shown to augment and increase wound healing and strength. Our goal was to investigate the combinatorial effect of complements C3 and C5 on wound healing. Methods. Each rat served as its own control where topical collagen was applied to one incision and 100 nM of C3 and C5 in collagen vehicle was applied to the other incision (n = 6). To compare between systemic effects, a sham group of rats (n = 6) was treated with collagen alone on one wound and saline on the other. At day 3, the tissue was examined for maximal breaking strength (MBS) and sectioned for histological examination. Results. There was a statistically significant 88% increase in MBS with the topical application of C3C5 when compared to sham wounds (n < 0.05). This was correlated with increased fibroblast and collagen deposition in the treated wounds. Furthermore, there appeared to be an additive hemostatic effect with the C3C5 combination. Conclusions. The combination of complements C3 and C5 as a topical application drug to skin wounds significantly increased wound healing maximum breaking strength as early as 3 days.

Thigh laxity after massive weight loss: a utilities outcomes assessment.

BACKGROUND: The presence of excess skin after massive weight loss, particularly in the thighs, not only contributes to a negative body image but can also lead to functional deficits in mobility. In the present study, we quantified the health state utility of living with excess skin in the thighs in an attempt to objectively establish the burden on the quality of life in patients living with excess thigh skin laxity. METHOD: Using visual analog scale (VAS), time trade-off (TTO), and standard gamble (SG), we compared the utility outcome scores for thigh skin excess with monocular and binocular blindness from a prospective sample of medical students and the general population. Utility scores were compared using paired t test. Linear regression was performed using age, race, and education as independent predictors of each of the utility scores. RESULTS: One hundred thirty-four prospective participants were enrolled during a 6-month period, and 112 participants met our inclusion criteria. The utility outcome scores for thigh lift (VAS, TTO, and SG, 0.77 ± 0.15, 0.90 ± 0.11, and 0.89 ± 0.14, respectively) were statistically different from binocular blindness (VAS, TTO, and SG, 0.37 ± 0.18, 0.70 ± 0.23, and 0.70 ± 0.26; P < 0.001), but other than VAS (0.67 ± 0.15, P < 0.001), similar to monocular blindness (TTO and SG, 0.89 ± 0.13 and 0.81 ± 0.14, respectively; P > 0.05). SG (0.89 ± 0.14 vs 0.97 ± 0.02, P = 0.003) and TTO (0.89 ± 0.11 vs 0.95 ± 0.03, P = 0.038) were different between general population and medical students, respectively, corresponding to 3.96 versus 1.80 potential years willing to be traded (P < 0.05). Additionally, SG was higher in whites versus nonwhites who were willing to take a potential 8% chance of mortality compared to 15%, respectively (P = 0.001), to achieve "perfect" health. CONCLUSIONS: We have objectified the utility of living with thigh deformity after massive weight loss. Our sample population if faced with the condition was willing to sacrifice a potential 3.6 years of life and potentially undergo a procedure with 11% chance of mortality to address excess thigh laxity.
