Efficacy of a 4-Week Nurse-Led Exercise Rehabilitation Program in Improving the Quality of Life in Women Receiving a Post-Mastectomy Reconstruction Using the Motiva ErgonomixTM Round SilkSurface.

We assessed the efficacy of a 4-week nurse-led exercise rehabilitation (ER) program in improving the quality of life (QOL) of breast cancer survivors (BCS) receiving an implant-based breast reconstruction. The eligible patients were equally randomized to either of both groups: the intervention group (n = 30; a 4-week nurse-led ER program) and the control group (n = 30; a 4-week physical therapist-supervised one). Both after a 4-week ER program and at baseline, the patients were evaluated for the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) and Fatigue Severity Scale (FSS) scores. There was a significantly higher degree of increase in global health status/QOL scores, physical functioning scores, role functioning scores, and emotional functioning scores at 4 weeks from baseline in the intervention group as compared with the control group (p = 0.001). However, there was a significantly higher degree of decrease in fatigue scores, nausea/vomiting scores, pain scores, dyspnea scores, and FSS scores in the intervention group as compared with the control group (p = 0.001). In conclusion, our results indicate that a 4-week nurse-led ER program might be effective in the QOL in BCS receiving a post-mastectomy implant-based reconstruction using the Motiva ErgonomixTM Round SilkSurface.

Expert consensus on the facial rejuvenation using the Mint Lift® in Koreans: Perspectives of plastic surgeons.

BACKGROUND: It would be mandatory for plastic surgeons to consider anthropometric and anatomical differences between Asians and Caucasians in performing facial rejuvenation procedures using absorbable threadlifts in Asians. METHODS: A consensus meeting was convened to discuss indications, treatment procedures, possible combination treatments, clinical outcomes, and safety of an absorbable polydioxanone (PDO) monofilament threadlift (Mint Lift® ; HansBiomed Co. Ltd., Seoul, Korea), for which the "Mint Aesthetics Expert Group" was organized with four Korean board-certified specialists in plastic and reconstructive surgery. RESULTS: Our recommendations are as follows: First, the entry and exit points should be determined considering anatomical characteristics of the face (Level of evidence III). Second, treatment procedures may vary depending on indications (Level of evidence III). Third, short-term efficacy and safety of facial rejuvenation using the Mint Lift® have been well documented (Level of evidence I and III). Third, facial rejuvenation using the Mint Lift® may be combined with a liposuction (Level of evidence III). CONCLUSIONS: Here, we propose expert consensus on facial rejuvenation using a novel absorbable PDO monofilament threadlift in Koreans. Of note, this is the only expert consensus prepared by board-certified specialists in plastic surgery in Korea. But more evidence-based efforts should be made to update and to expand the current recommendations.

Four-Year Interim Results of the Safety of Augmentation Mammaplasty Using the Motiva Ergonomix™ Round SilkSurface: A Multicenter, Retrospective Study.

BACKGROUND: The Motiva Ergonomix™ Round SilkSurface (Establishment Labs Holdings Inc., Alajuela, Costa Rica) is the fifth generation of a silicone gel-filled breast implant that is commercially available in Korea. OBJECTIVES: In this study, we describe 4-year interim results of the safety of augmentation mammaplasty using the Motiva Ergonomix™ Round SilkSurface in Korean women. METHODS: In the current multicenter, retrospective study, we performed a retrospective review of medical records of a total of 1314 patients who received augmentation mammaplasty using the Motiva Ergonomix™ Round SilkSurface at our hospitals between September 1, 2016, and August 31, 2020. For safety assessment, we analyzed incidences of postoperative complications and Kaplan-Meier complication-free survival of the patients. RESULTS: We included a total of 873 patients (1746 breasts, mean age = 32.18 ± 6.88 years) in the current study. There were a total of 111 cases (12.70%) of postoperative complications; these include 24 cases (2.70%) of early seroma, 18 cases (2.10%) of hematoma, 18 cases (2.10%) of capsular contracture, 17 cases (1.95%) of dissatisfaction with shape, 16 cases (1.83%) of dissatisfaction with size, 9 cases (1.03%) of asymmetry, 6 cases (0.70%) of infection and 3 cases (0.34%) of rippling. Moreover, time-to-events were estimated at 918.34 ± 36.22 days (95% CI 845.44-988.52). CONCLUSIONS: Here, we describe 4-year interim results of the safety of augmentation mammaplasty using the Motiva Ergonomix™ Round SilkSurface in Korean women in a non-manufacturer-sponsored study. But further large-scale, prospective, multicenter studies with a long period of follow-up are warranted to establish our results.

Alcohol Intoxication-Related Soft Tissue Injuries in Patients With Orbital Wall Fractures.

BACKGROUND: To date, involvement of alcohol intoxication (AI) in the occurrence of traumatic bone injuries has been well described in the literature. Still, however, there is a paucity of data regarding its involvement with soft tissue injuries in the oral and maxillofacial region. Considering that it is one of the significant predisposing factors that are involved in facial bone fractures in assault victims, we have speculated that they are also vulnerable to soft tissue injuries. We therefore examined the incidence, type and, pattern of soft tissue injuries in patients with trauma owing to the AI in a single-institution setting. MATERIALS AND METHODS: A total of 488 patients underwent reconstructive surgery for orbital wall fracture at our medical institution between 2012 and 2017. Of these, 162 eligible patients were enrolled in the present study; they were divided into 2 groups (the AI group and the control group) based on a history of the AI. Then, we compared baseline and clinical characteristics, including the incidence, type, and pattern of soft tissue injury, between the 2 groups. RESULTS: In our series, assault was the most common cause of traumatic injuries. We found that the patients with AI were at increased risks of preoperatively developing subconjunctival hemorrhage and diplopia and postoperatively developing infraorbital nerve (ION) hypesthesia. CONCLUSIONS: In conclusion, our results indicate that the AI is closely associated with the preoperative risks of subconjunctival hemorrhage and diplopia and the postoperative risks of ION hypesthesia. But further large-scale, multicenter studies are warranted to establish our results.

Association between sphingosine-1-phosphate-induced signal transduction via mitogen-activated protein kinase pathways and keloid formation.

We conducted this experimental study to analyze the relationship between sphingosine-1-phosphate (S1P)-induced mitogen-activated protein (MAP) kinase pathways and keloid formation. We collected samples of the normal tissue and the keloid tissue from 10 normal healthy individuals and 12 patients with keloid scars, respectively. Then, we compared the level of sphingosine-1-phosphate receptor (S1PR1/S1PR2) mRNA/protein expression between the normal tissue and the keloid tissue. Moreover, we also compared the level of S1PR protein expression, that of S1P-induced COL1A1 (collagen Type I, α-1 chain) expression, that of S1P-induced JNK/ERK phosphorylation, that of S1P-induced COL1A1 expression following the treatment with 30 µM PD98059 (ERK inhibitor) or 30 µM SP600125 (JNK inhibitor) and that of S1P-induced COL1A1 expression following the treatment with W146 (S1PR1 inhibitor) or JTE013 (S1PR2 inhibitor) between the normal fibroblasts and the keloid fibroblasts. We found that the level of S1PR1/S1PR2 mRNA/protein expression was significantly higher in the keloid tissue as compared with the normal tissue. Our results also showed that the level of S1P-induced COL1A1 expression and that of S1P-induced JNK/ERK phosphorylation were significantly higher in the keloid fibroblasts as compared with the normal ones (P < 0.05). Furthermore, there were significant decreases in the level of S1P-induced COL1A1 expression when the keloid fibroblasts were treated with 30 µM SP600125 or 30 µM PD98059 and that of S1P-induced COL1A1 expression when the treated with 100 nM W146 or 100 nM JTE013 (P < 0.05). Our results indicate that S1P-induced signal transduction is associated with increased collagen synthesis via S1PR-mediated signaling pathways in the keloid tissue.
