Reduction Mammoplasties: Risk Factors and Early Complications-About 1442 Cases.

BACKGROUND: Breast reduction surgery is a widely performed plastic surgery procedure. The incidence of such complications has been steadily decreasing in recent years but is still nonetheless 5.6%. The primary aim of this study was to analyze the incidence of the main postoperative complications of breast reduction surgery. In addition, we identified cause-and-effect links between complications and characteristics of the patients, such as smoking, age, weight resection, BMI, and wound drainage. MATERIALS AND METHODS: This retrospective study was performed on a population of 1442 women who underwent breast reduction surgery between January 2016 and October 2022 in the plastic surgery unit at Saint-Louis Hospital, Paris, France. At the follow-up examination, we evaluated the patients for complications. RESULTS: The average resection weight was 1297.7 g in a population for which the average BMI was 28.9. We found 19.9% rate of total complications, of which 3.5% were major complications. We found that only the resection weight was a risk factor for complications. DISCUSSION: The main strength of our study is the size of our sample. The large number of patients allowed us to conduct numerous analyses and obtain significant results despite the rarity of certain events. This large cohort was also responsible for the high statistical power of our results. CONCLUSION: The risk of developing a postoperative infection was 7.5% for resections of less than 2.4 kg, increasing to 13.9 % when greater than that. Thus, the administration of prophylactic antibiotic therapy to affected women to reduce the risk of infection is a distinct consideration. For the other factors, while none of them appeared to promote the occurrence of adverse events and, therefore, do not formally contraindicate breast reduction surgery, some preventive measures still strike us as being relevant, such as blade drainage, weight loss, diabetes control, and smoking cessation.

Short- and long-term morbidity after Taylor flap (oblique rectus abdominis flap) for perineal reconstruction after abdominoperineal resection: A single-center series of 140 patients.

BACKGROUND: Abdominoperineal resection (APR) leads to a substantial loss of tissue and a high rate of complications. The Taylor flap is a musculocutaneous flap used in reconstruction after APR. OBJECTIVES: We aimed to analyze the short and long-term morbidity of reconstruction with a Taylor flap (oblique rectus abdominis flap) after APR and to identify the risk factors for postoperative complications. METHODS: We retrospectively included all patients who had undergone APR with immediate reconstruction with a Taylor flap in our department between July 2000 and June 2018. Demographics, oncological data, treatment, and short- and long-term morbidity were reviewed. RESULTS: Among the 140 patients included, we identified early minor complications in 42 patients (30%) and 14 early major complications (10%). Total necrosis of the flap requiring its removal occurred in four patients (2.8%). Eleven patients (7.9%) presented with a midline incision hernia, and seven (5%) presented with a subcostal incision hernia. No perineal hernia was found. No risk factors for the complications were identified. CONCLUSION: The Taylor flap is a safe procedure with few complications and limited donor site morbidity. Moreover, it prevents perineal hernias. These results confirm that the Taylor flap is a well-suited procedure for reconstruction after APR.

The Acute Achilles Tendon Rupture: An Evidence-Based Approach from the Diagnosis to the Treatment.

Background and Objective: Acute Achilles tendon rupture (AATR) is a common injury with a significant impact on daily living. Although various systematic reviews and meta-analyses have been written on the topic, no actual consensus exists on the best treatment. We aimed to collect the highest quality of evidence on the subject and to produce a document to which to refer, from the diagnosis to the final treatment. Material and Methods: Inclusion criteria were systematic reviews discussing Achilles tendon rupture, concerning either diagnostic criteria, classification, or treatment; English language; clearly stated inclusion and exclusion criteria for patients' selection. Results: Thirteen systematic reviews were included in the study. A strong consensus exists about the higher risk of re-rupture associated with non-operative treatment and a higher risk of complications associated with surgical repair. Conclusions: The combination of minimally invasive repair and accelerated functional rehabilitation seems to offer the best results in the treatment of Achilles tendon rupture.

Epidemiology and Prevention of Breast Prosthesis Capsular Contracture Recurrence.

INTRODUCTION: Baker grade III and IV breast prosthesis capsular contractures represent a major problem for patients undergoing mammoplasties. The risk factors involved in recurrence are debated, and the best surgical approach for their prevention is not established. The objective was to identify these. MATERIALS AND METHODS: We carried out a retrospective study of patients operated on for capsular contracture at the Saint-Louis Hospital in Paris from 2012 to 2014. The characteristics at inclusion were compared so as to determine the risk factors of recurrence. The surgical approaches were compared between the patients with recurrence and those without at 5 years. RESULTS: Of the 100 patients included, 24 had a recurrence. The minimal follow-up was 5 years. No risk factors of recurrence of capsular contracture were identified. The surgical approach associated with the lowest rate of recurrence was anterior capsulectomy [OR total capsulectomy = 2.36 (0.73; 8.037) OR capsulotomy = 4.33 (1.37; 14.81)] (p < 0.040) with alteration of the volume of the implant, whether greater or less than initially [OR greater volume = 0.30 (0.096; 0.83); OR smaller volume = 0.14 (0.008; 0.85)] (p < 0.018). CONCLUSION: The occurrence of capsular contracture is a major problem with prosthetic breast surgery. The main risk factors identified to date are essentially in regard to the occurrence of a first episode. No significant risk factors for recurrence were identified. The best prevention appears to be an anterior capsulectomy with reducing the volume of the implant.

[Skin aging: Pathophysiology and innovative therapies]. / Vieillissement cutané - Physiopathologie et thérapies innovantes.

One of the major challenges of the 21st century is the fight against aging, defined as a set of physiological mechanisms altering the physical and intellectual capacities of human beings. Aging of the skin is only one visible part of this process. It is associated with major healing defects linked in part to the alteration of the biomechanical properties of skin cells, mainly dermal fibroblasts. The immune system, another key component in maintaining skin homeostasis and the efficient healing of wounds, also suffers the effects of time: the consequent skin immunosenescence would limit the anti-infectious and vaccine response, while promoting a pro-tumor environment. The main skin damages due to aging, whether intrinsic or extrinsic, will be detailed before listing the effective anti-aging strategies to combat age-related dermal and epidermal stigmas.

TITLE: Vieillissement cutané - Physiopathologie et thérapies innovantes. ABSTRACT: Un des enjeux majeurs de ce XXIe siècle est la lutte contre le vieillissement, défini comme un ensemble de mécanismes physiologiques altérant les capacités physiques et intellectuelles de l'organisme. Le vieillissement de la peau n'est qu'un trait visible de ce processus. Il est associé à des défauts de cicatrisation majeurs liés à l'altération des propriétés biomécaniques des cellules cutanées, essentiellement des fibroblastes dermiques. Le système immunitaire, autre composante clé du maintien de l'homéostasie cutanée et du bon déroulement de la cicatrisation des plaies, subit aussi les effets du temps : l'immunosénescence cutanée consécutive limiterait la réponse anti-infectieuse et vaccinale, tout en favorisant un environnement pro-tumoral. Les principales atteintes cutanées dues au vieillissement, que celui-ci soit intrinsèque ou extrinsèque, seront détaillées avant d'énumérer les stratégies anti-âges efficaces pour lutter contre les stigmates dermiques et épidermiques liées à l'âge.

A Melanoma-Tailored Next-Generation Sequencing Panel Coupled with a Comprehensive Analysis to Improve Routine Melanoma Genotyping.

BACKGROUND: Tumor molecular deciphering is crucial in clinical management. Pan-cancer next-generation sequencing panels have moved towards exhaustive molecular characterization. However, because of treatment resistance and the growing emergence of pharmacological targets, tumor-specific customized panels are needed to guide therapeutic strategies. OBJECTIVE: The objective of this study was to present such a customized next-generation sequencing panel in melanoma. METHODS: Melanoma patients with somatic molecular profiling performed as part of routine care were included. High-throughput sequencing was performed with a melanoma tailored next-generation sequencing panel of 64 genes involved in molecular classification, prognosis, theranostic, and therapeutic resistance. Single nucleotide variants and copy number variations were screened, and a comprehensive molecular analysis identified clinically relevant alterations. RESULTS: Four hundred and twenty-one melanoma cases were analyzed (before any treatment initiation for 94.8% of patients). After bioinformatic prioritization, we uncovered 561 single nucleotide variants, 164 copy number variations, and four splice-site mutations. At least one alteration was detected in 368 (87.4%) lesions, with BRAF, NRAS, CDKN2A, CCND1, and MET as the most frequently altered genes. Among patients with BRAFV600 mutated melanoma, 44.5% (77 of 173) harbored at least one concurrent alteration driving potential resistance to mitogen-activated protein kinase inhibitors. In patients with RAS hotspot mutated lesions and in patients with neither BRAFV600 nor RAS hotspot mutations, alterations constituting potential pharmacological targets were found in 56.9% (66 of 116) and 47.7% (63 of 132) of cases, respectively. CONCLUSIONS: Our tailored next-generation sequencing assay coupled with a comprehensive analysis may improve therapeutic management in a significant number of patients with melanoma. Updating such a panel and implementing multi-omic approaches will further enhance patients' clinical management.

Intermittent Versus Continuous Dosing of MAPK Inhibitors in the Treatment of BRAF-Mutated Melanoma.

The development of BRAF and MEK inhibitors (BRAFi/MEKi) has led to major advances in melanoma treatment. However, the emergence of resistance mechanisms limits the benefit duration and a complete response occurs in less than 20% of patients receiving BRAFi ± MEKi. In this study, we evaluated the impact of an intermittent versus continuous dosing schedule of BRAF/MEK inhibition in a melanoma model mildly sensitive to a BRAF inhibitor. The combination of a BRAFi with three different MEKi was studied with a continuous or intermittent dosing schedule in vivo, in a xenografted melanoma model and ex vivo using histoculture drug response assays (HDRAs) of patient-derived xenografts (PDX). To further understand the underlying molecular mechanisms of therapeutic efficacy, a biomarker pharmacodynamic readout was evaluated. An equal impact on tumor growth was observed in monotherapy or bitherapy regimens whether we used continuous and intermittent dosing schedules, with no significant differences in biomarkers expression between the treatments. The antitumoral effect was mostly due to modulations of expression of cell cycle and apoptotic mediators. Moreover, ex vivo studies did not show significant differences between the dosing schedules. In this context, our preclinical and pharmacodynamic results converged to show the similarity between intermittent and continuous treatments with either BRAFi or MEKi alone or with the combination of both.

A 10-Year Follow-Up Experience of 383 Patients with Bilateral Smooth Inflatable Breast Implants Filled with Saline Solution.

INTRODUCTION: In light of the concerns regarding the occurrence of anaplastic large-cell lymphoma, seromas, and scar capsules, there appears to be merit in analysis and presentation of the results of our series of inflatable smooth implants filled with saline solution, for which the follow-up was more than 10 years. PATIENTS AND METHOD: We carried out a retrospective study, including all of the patients who underwent a first breast implant for cosmetic reasons, between 2003 and 2006. RESULTS: A total of 383 patients with 766 smooth implants filled with saline solution were included in our study. No cases of lymphoma and seroma were diagnosed. Eleven patients exhibited a postoperative hematoma, and four went on to develop a capsule. Twenty-two patients (5.7%) developed a Baker Grade III or IV capsule that required revision surgery. Two patients (0.5%) opted for a bilateral prosthesis replacement due to visual rippling. In total, there were 26 (3.4%) early deflations of prostheses. DISCUSSION: There is not a statistically significant correlation between the occurrence of hematomas and the formation of a capsule. We found a lower shell rate with smooth-walled versus textured implants. The fact of having a decline of 10 years allows to be exhaustive. As for wrinkling and ripples, their occurrence has not been increased by the use of inflatable retropectoral implants. CONCLUSION: Smooth inflatable implants filled with saline solution have numerous advantages such as the possibility of a very small approach route and perioperative adaptability of the volume. In light of the lack of indication of anaplastic large-cell lymphoma with smooth implants, they are clearly an attractive alternative to textured implants filled with silicone gel.

Prediction of major adverse kidney events in critically ill burn patients.

OBJECTIVE: We aimed at assessing the predictive value of plasmatic Neutrophil Gelatinase Associated Lipocalin (pNGAL) at admission and severity scores to predict major adverse kidney events (MAKE, defined as death and/or need for renal replacement therapy (RRT) and/or non-renal recovery at day 90) in critically ill burn patients. MATERIAL AND METHODS: Single-center cohort study in a burn critical care unit in a tertiary center, including all consecutive severely burn patients (total burned body surface >20%) from January 2012 until January 2015 with a pNGAL dosage at admission. Reclassification of patients was assessed by Integrated Discrimination Improvement (IDI). MEASUREMENTS AND RESULTS: 87 patients were included. Mean age was 47.7 (IQ 25-75: 33.4-65.2) years; total burn body surface area was 40 (IQ 25-75: 30-55) % and ICU mortality 36%. 39 (44.8%) patients presented a MAKE, 32 (88.9%) patients died at day 90. pNGAL was higher in the MAKE group (423 [IQ 25-75: 327-518]pg/mL vs 184 [IQ 25-75: 147-220]pg/mL, p<0.001). In multivariate analysis, pNGAL and abbreviated burn severity index (ABSI) remained associated with MAKE (OR 1.005 [CI 95% 1.0005-1.009], p=0.03 and OR 1.682 [CI95%1.038-2.726], p=0.035 respectively). Adding pNGAL to abbreviated burn severity index, simplified organ failure assessment and the simplified acute physiology score 2 did outperform clinical scores for the prediction of MAKE and AKI and for most severe forms of AKI and allowed a statistically significant reclassification of patients compared to ABSI for MAKE, RRT, AKI at Day 7 and AKI during hospitalization with a number of patients needed to screen to detect one extra episode of MAKE was 44, 13 for severe AKI and 15 for AKI. CONCLUSIONS: pNGAL at admission is associated with the risk of MAKE in this population, and outperform severity scores when associated. Interventional studies are now needed to assess if impact of biomarkers-guided strategies would improve outcome.

Improving Safety after Abdominoplasty: A Retrospective Review of 1128 Cases.

BACKGROUND: Over the course of several decades, abdominoplasty has undergone numerous improvements, thereby improving patient safety. The choice of the site of the incision and the extent of the detachment directly influence the occurrence of the main complications. METHODS: A retrospective study was carried out involving 1128 patients who underwent abdominoplasty between January of 1990 and June of 2014. The main postoperative complications were analyzed. RESULTS: The hematoma rate was 5.7 percent; in addition, infections (4.5 percent), cutaneous necrosis (2.7 percent), seromas (2.7 percent), disunions (1.3 percent), and deep venous thrombosis (0.2 percent) were observed. Three main risk factors for complications were highlighted: age older than 40 years, obesity, and smoking. The authors noted a significant variation in the rate of complications depending on the technique used, with a substantial rate of necrosis in case of inverted-T abdominoplasty. Liposuction was not a source of complications, regardless of the patient's background or the type of intervention. CONCLUSIONS: Abdominoplasty is currently a reliable technique that allows the abdomen to be repaired and quality of life to be restored. Other means remain to be explored to improve the overall treatment and to move toward a maximal reduction of the risks. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Ongoing Development and Evaluation of a Method of Telemedicine: Burn Care Management With a Smartphone.

In cases involving small burns in patients without a comorbidity or associated pathology, a referral from a surgeon is necessary and sometimes it cannot be ascertained when the patient is not brought in by a specialized team. The purpose of this retrospective study was to evaluate the quality of our method for performing telemedicine. This retrospective study included the 323 patients who were initially treated using the telemedicine system implemented between 2011 and 2016. This procedure only involved patients burned over a small portion of their body's surface area (ie, ≤15%) who were between 15 and 75 years of age and who did not have a major comorbidity. The purpose of the procedure was to evaluate the need for surgery. The initial diagnosis regarding the need for a surgical procedure was accurate in 94.4% (305/323) of the cases. Eleven patients (3.4%) were transferred unnecessarily as they ultimately did not require surgery, and seven patients (2.2%) were ultimately transferred even though the need for surgery was not initially established at the time that the pictures were viewed. No initial errors in the photographic evaluation caused a worsening in the life-threatening, functional, or aesthetic prognoses. We have recently opted to use telemedicine for initial patient management. In 94.4% of cases, the opinion that was provided was accurate. Only 3.2% of the patients for whom outpatient treatment was recommended ultimately underwent surgery without subsequently experiencing the slightest injury due to any delay in therapy. Although it will never replace clinical examination, these results have encouraged us to develop telemedicine based on digital photography.

The M-Y Axilloplasty After Massive Weight Loss: Analysis of 159 Consecutive Patients.

BACKGROUND: Brachioplasties often culminate in unsightly scars that are a source of disappointment to patients. We aimed to evaluate the results of M-Y axilloplasty following massive weight loss. PATIENTS: We performed a retrospective assessment of our technique for brachioplasty with an M-Y axilloplasty in 159 female patients after massive weight loss. This retrospective study covered a study period of 10 years. METHOD: After substantial lipoaspiration, the incision is placed on the internal side of the arm, with an M-shaped axilloplasty. RESULTS: The satisfaction rate was 154/159 (97%) and 120/159 (75.5%) being happy with their esthetic results. Nineteen percent (30/159) of the patients had complications and 12/159 (7.5%) underwent a surgical revision. CONCLUSION: M-Y axilloplasty for brachioplasty is an effective procedure for treating women who are unhappy with their upper arms after massive weight loss. The satisfaction rate is high, and the result leaves no excess skin on the chest. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

Closed-Suction Drains After Subcutaneous Mastectomy for Gynecomastia: Do They Reduce Complications? A Different Approach.

INTRODUCTION: We read the manuscript entitled "Closed-suction drains after subcutaneous mastectomy for gynecomastia: do they reduce complications? ¼ published by Chao et al. (Aesthetic Plast Surg, 2017. https://doi.org/10.1007/s00266-017-0959-z ). They have concluded that drains may reduce rates of seromas requiring needle aspiration after surgical treatment, but also that there are several adverse effects of drains: patients' discomfort, anxiety, cost and additional clinic visits. They also recalled several limitations: (1) bias in terms of surgeon decision to place a drain, (2) nuances in technique. Here we want to discuss our different technique of drainage. To prevent all the disadvantages, we have chosen to replace closed-suction drains with silicone blades and a wide scar opening at the level of the periareolar scar. METHOD: We carried out a retrospective study in our department in 2016. RESULTS: This series consisted of 83 patients (153 breasts) aged 26.7 years of age (15-67), with an average BMI of 28.6 (19.5-39). All were followed during the 12 months postoperatively. We considered here only grade 1-2a gynecomastia with palpable fibrous glandular tissue. The surgical procedure consisted of initial liposuction, then open surgical excision via the periareolar approach. We did not notice any seroma or collection requiring intervention. However, 4 patients (4/153; 2.6%) had hematomas requiring intervention the day after surgery. CONCLUSION: Our technique presents a lot of advantages, reduced length of stay in the hospital, costs from drain site care and clinic visits, patients' discomfort, and antibiotic prescriptions.
