Vertical Scar Mastopexy With a Centrally Based Auto-Augmentation Flap.

The authors describe their technique for vertical scar mastopexy with a centrally based auto-augmentation flap. Since 2011, the authors have performed this procedure in 212 patients and found that this operative technique has allowed us to achieve reproducible aesthetic outcomes while minimizing complications. Vertical scar mastopexy with a centrally based auto-augmentation flap is an excellent procedure for patients with breast ptosis who desire improved breast shape and superior pole fullness without the use of a breast implant. The perioperative management and detailed steps of the procedure are outlined.

Comparison of Clinical Outcomes of Lower Extremity Burns in Diabetic and Nondiabetic Patients: A Retrospective Analysis.

Diabetes mellitus is an increasingly prevalent chronic disease that leads to long-term health consequences. Some long-term clinical sequelae of diabetes include coronary artery disease, peripheral vascular disease, peripheral neuropathy, and impaired wound healing. These can increase hospital stay and complications such as wound infections and amputations among patients with lower extremity burns. A retrospective analysis was performed of all isolated lower extremity burns from a single tertiary burn care center from 2006 to 2017. Patients were stratified by diabetic status and the incidence of lower extremity amputations was the primary outcome. Multivariable regression was used to model the association between diabetes and amputations, adjusting for patient and injury characteristics. A total of 198 patients were identified as meeting inclusion criteria, 160 were nondiabetic and 38 were diabetic. Age was significantly different between nondiabetic and diabetic patients; mean age was 46 ± 18 vs 62 ± 17 years (P < .0001). Length of stay was also significantly different, median length of stay was 11 (interquartile range 7-15) vs 18 (interquartile range 12-24; P < .001), with diabetic patients staying longer. There was a significantly greater proportion of diabetic patients that had an amputation (control 4% vs diabetic 29%; P < .0001). After adjustment for patient and injury characteristics, there was a significant association between diabetes and amputation (P = .002). Among patients with isolated lower extremity burns, those with a preexisting condition of diabetes had a longer hospitalization and increased amputations, despite similar size of burn. Diabetes is an important risk factor to acknowledge in patients with these injuries to optimize care.

The impact of surgical manipulation on lower lateral cartilage stiffness.

BACKGROUND: Cephalic trimming of the alar (or lower lateral) cartilage may cause weakening leading to external nasal valve collapse. Numerous methods have been proposed to combat this weakening in order to maintain lateral crural stiffness. The purpose of this study was to quantify the effect of mucosal stripping, cephalic trimming, cephalic turn-in flap, and lateral crural strut grafting on lateral crural stiffness. METHODS: In situ cyclic compressive loading was performed on eight lateral crura in 4 fresh frozen cadaveric specimens. Testing was performed on the unaltered degloved cartilage (intact) and following each of the following interventions: mucosal stripping, cephalic turn-in flap, cephalic trimming, and lateral crural strut grafting. Linear regression of the generated force-displacement curves was used to calculate stiffness. Each intervention was compared to the intact cartilage. RESULTS: Alar cartilage of all of the specimens demonstrated a linear response to compressive loading. Intact cartilage had a mean stiffness of 3.53 N/mm. Mucosal stripping and cephalic turn-in flaps yielded similar stiffness values to intact cartilage. Cephalic trimming reduced stiffness in all cases by a mean of 1.09 N/mm (p = 0.003). Lateral crural strut grafting significantly increased stiffness by a mean of 3.67 N/mm (p = 0.0001). CONCLUSIONS: Cephalic trimming leads to decreased lateral crural stiffness in cadaveric specimens. Cephalic turn-in flaps restore pre-trimmed stiffness, and lateral crural strut grafting increases overall stiffness of the cartilage. These findings should be considered in patients undergoing rhinoplasty, particularly if there are concerns regarding potential external valve collapse.

Best Evidence in Emergency Medicine (BEEM) rater scores correlate with publications' future citations.

BACKGROUND: The "BEEM" (best evidence in emergency medicine) rater scale was created for emergency physicians (EPs) to evaluate the physician-derived clinical relevance score of recently published, emergency medicine (EM)-related studies. BEEM therefore is designed to help make EPs aware of studies most likely to confirm or change current clinical practice. OBJECTIVES: The objective was to validate the BEEM rater score as a predictor of literature citation, using a bibliometric construct of clinical relevance to EM based on author-, document-, and journal-level measures (first and last author h-indices, number of authors including corporate and group authors, citations from date of publication to 2011, and journal impact factor scores) and study characteristics (design, category, and sample size). METHODS: Each month from 2007 through 2012, approximately 200 EPs from around the world voluntarily reviewed the titles and conclusions of recently published EM-related studies identified by BEEM faculty via the McMaster Health Information Research Unit. Using the BEEM rater scale, a reliable seven-item instrument that evaluates the clinical relevance of studies, raters independently assigned BEEM scores to approximately 10 to 20 articles each month. Two investigators independently abstracted the bibliometric indices for these articles. A citation rate for each article was calculated by dividing the Thomson Reuters Web of Science (WoS) total citation count by the number of years in publication. BEEM rater scores were correlated with the citation rate using Spearman's rho. The performance of the BEEM rater score was assessed for each article using negative binomial regression with composite citation count as the criterion standard, while controlling for other independent bibliometric variables in three models. RESULTS: The BEEM raters evaluated 605 articles with a mean (±SD) BEEM score of 3.84 (±0.7) and a median BEEM score of 3.85 (interquartile range = 3.38 to 4.30). Articles were primarily therapeutic (59%) and diagnostic (27%), with various designs, including 37% systematic reviews, 32% randomized controlled trials (RCTs), and 30% observational designs. The citation rate and BEEM rater score correlated positively (0.144), while the BEEM rater score and the Journal Citation Report (JCR) impact factor score were minimally correlated (0.053). In the first model, the BEEM rater score significantly predicted WoS citation rate (p < 0.0001) with an odds ratio (OR) of 1.24 (95% confidence interval [CI] = 1.106 to 1.402). In subsequent models adjusting for the JCR impact factor score, the h-indices of the first and last authors, number of authors, and study design, the BEEM rater score was not significant (p = 0.08). CONCLUSIONS: To the best of our knowledge, the BEEM rater score is the only known measure of clinical relevance. It has a high interrater reliability and face validity and correlates with future citations. Future research should assess this instrument against alternative constructs of clinical relevance.
