Lessons Learned from Three Different Acellular Dermal Matrices in Direct-to-Implant Breast Reconstruction

Modern Plastic Surgery 2021年第1期11卷 22-35页

作者： Claas Spengler Roland Mett Frank Masberg peter M. vogt Tobias R. Mett Department of Plastic Reconstructive Aesthetic Surgery HELIOS Klinik Schwerin Schwerin Germany Department of Plastic Aesthetic Hand and Reconstructive Surgery Hannover Medical School Hannover Germany

The aim of the study was to show significant differences regarding postoperative complications and outcomes using three different Acellular Dermal Matrices (ADM), namely Epiflex®, Strattice® and Braxon®, in immediate implant-based subpectoral breast reconstruction cases. Background: The use of Acellular Dermal Matrices for implant-based breast reconstruction cases continues to evolve. There is a wide variety of products which differ significantly in their biological features. It remains unclear if and how these differences manifest in clinical practice. Methods: 82 cases of primary breast reconstruction in the Department of Plastic and Aesthetic Surgery of HELIOS Clinics Schwerin, Germany between 2010 and 2018 were analyzed. 25 patients received Strattice® acellular dermal matrix (SADM), 22 cases Epiflex® acellular dermal matrix (EADM) and the remaining 35 cases Braxon® acellular dermal matrix (BADM). The mean follow-up was 1.8 years. Cases were analyzed regarding minor or major complications and rate of capsular contracture grade III or IV (Baker Classification). Results: The overall complication rate was 34.1% for all groups (SADM = 40%, EADM = 50%, BADM = 20%, p-value = 0.051). Of all cases, 6 patients underwent implant exchange or secondary autologous reconstruction due to capsular contracture (7.3%). The mean time between revision due

When you've worked so hard to get the first job after college, the last thing you want1 is to screw it up2. Sadly, new grads3 do it all the time. The problem rarely stems from4 lack of knowledge or poor technical skills. It often goes back to something simpler: Your persona5 in the workplace, particularly during your first few weeks on the job.

Utility of different glycemic control metrics for optimizing management of diabetes

引用

World Journal of Diabetes 2015年第1期6卷 17-29页

作者： Klaus-Dieter Kohnert peter Heinke Lutz vogt Eckhard Salzsieder Institute of Diabetes "Gerhardt Katsch" Diabetes Service Center

The benchmark for assessing quality of long-term glycemic control and adjustment of therapy is currently glycated hemoglobin(Hb A1c). Despite its importance as an indicator for the development of diabeticcomplications, recent studies have revealed that this metric has some limitations; it conveys a rather complex message, which has to be taken into consideration for diabetes screening and treatment. On the basis of recent clinical trials, the relationship between Hb A1 c and cardiovascular outcomes in long-standing diabetes has been called into question. It becomes obvious that other surrogate and biomarkers are needed to better predict cardiovascular diabetes complications and assess efficiency of therapy. Glycated albumin, fructosamin, and 1,5-anhydroglucitol have received growing interest as alternative markers of glycemic control. In addition to measures of hyperglycemia, advanced glucose monitoring methods became available. An indispensible adjunct to Hb A1 c in routine diabetes care is selfmonitoring of blood glucose. This monitoring method is now widely used, as it provides immediate feedback to patients on short-term changes, involving fasting, preprandial, and postprandial glucose levels. Beyond the traditional metrics, glycemic variability has been identified as a predictor of hypoglycemia, and it might also be implicated in the pathogenesis of vascular diabetes complications. Assessment of glycemic variability is thus important, but exact quantification requires frequently sampled glucose measurements. In order to optimize diabetes treatment, there is a need for both key metrics of glycemic control on a day-to-day basis and for more advanced, user-friendly monitoring methods. In addition to traditional discontinuous glucose testing, continuous glucose sensing has become a useful tool to reveal insufficient glycemic management. This new technology is particularly effective in patients with complicated diabetes and provides the opportunity to characterize g
