Patient-reported Outcomes Utilizing the Breast-Q Questionnaire After Breast Conserving Surgery With and Without Oncoplastic Breast Surgery: A Systematic Review and Meta-analysis. Aesthet Surg J 2024:sjae002. [PMID: 38195101 DOI: 10.1093/asj/sjae002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Revised: 12/15/2023] [Accepted: 12/20/2023] [Indexed: 01/11/2024] Open
Abstract
Oncoplastic breast surgery (OBS) arose to decrease the deformity following breast conserving surgery (BCS) for breast cancer. In this meta-analysis (MA), we pool Breast-Q™ questionnaire data to compare quality of life (QOL) in breast cancer patients who received BCS alone or in combination with Level I or II oncoplastic breast surgery (BCS+OBS). All relevant databases were searched following the PRISMA and QUOROM guidelines. All prospective or retrospective studies with a BCS or BCS+OBS cohort that reported QOL as assessed with the Breast-Q™ questionnaire were eligible. Fifty-five studies (75 distinct patient cohorts; 11,186 patients) were included in the MA, with 12 studies reporting both pre- and postoperative values and eligible for a pairwise MA. The pairwise MA showed a significant postoperative improvement in the overall satisfaction with the breast (MD +8.0%, p=0.003) and in the psychosocial well-being (MD +9.2%, 3.5-14.8, p=0.001) of the entire cohort (BCS and BCS+OBS). A subgroup MA of proportions highlighted a superiority of BCS+OBS to BCS in terms of overall satisfaction with the breast (72.0%, 68.0-76.1, versus 62.9%, 58.3-67.5; p=0.02) and psychosocial well-being (78.9%, 71.5-86.4, versus 73.3%, 67.3-76.5, p=0.0001). A leave-one-out sensitivity analysis confirmed the results of the pairwise MA and the MA of proportions. Oncoplastic breast surgery effectively improves QoL based on the patient-reported outcomes assessed using the Breast-Q™ questionnaire. The improvements were associated with acceptable complication rates, further supporting the use of BCS followed by OBS where mastectomy would otherwise be necessary.

Abstract
BACKGROUND Hybrid breast reconstruction (HBR) combines silicone implants with fat grafting to improve implant coverage, treating local tissue deficiencies and leading to a more natural breast appearance. Recent data also indicated less capsular contracture after HBR. The authors developed a novel technique and animal model of cell-assisted (CA) HBR to illuminate its effects on capsular contracture. METHODS Animals received silicone implants in a dorsal submuscular pocket. Although animals of the HBR group received fat grafting around the implant without stem cell enrichment, rats of the CA-HBR1 and the CA-HBR2 groups received stem cell-enriched fat grafting with 2 × 10 6 and 4 × 10 6 adipose-derived stem cells immediately after implant insertion. On day 60, animals underwent sonography and elastography imaging and were euthanized, and outcome analysis was performed by means of histology, immunohistochemistry, chemical collagen quantification, and gene expression analysis. RESULTS With this novel technique, long-term survival of adipose-derived stem cells within the implant pocket was demonstrated after 60 days after implant insertion. CA-HBR led to significantly reduced thickness and collagen density of capsular contractures. In addition, CA-HBR resulted in reduced fibrotic responses with less occurrence of collagen type I and transforming growth factor-β in capsule tissue. Moreover, the addition of stem cells suppressed fibrotic and inflammatory responses on a genetic level with significant underexpression of collagen type I and transforming growth factor-β1. CONCLUSIONS With this new technique and animal model, the authors observed a preventive effect on capsular contracture substantiating the basis of clinical outcomes of HBR. The authors propose that the addition of stem cells to HBR might booster its beneficial results. CLINICAL RELEVANCE STATEMENT Stem cell-enriched fat grafting around silicone implants may reduce the risk for capsular contracture after silicone breast implantation. While fat grafting alone already shows beneficial effects, the addition of stem cells to the fat graft can potentiate this effect.

Enzymatic Debridement in Geriatric Burn Patients—A Reliable Option for Selective Eschar Removal. J Clin Med 2023; 12:jcm12072633. [PMID: 37048716 PMCID: PMC10095072 DOI: 10.3390/jcm12072633] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2023] [Revised: 03/20/2023] [Accepted: 03/29/2023] [Indexed: 04/05/2023] Open
Abstract
The treatment of geriatric burn patients represents a major challenge in burn care. The objective of this study was to evaluate the efficacy of enzymatic debridement (ED) in geriatric burn patients. Adult patients who received ED for treatment of mixed pattern and full thickness burns (August 2017–October 2022) were included in this study and grouped in the younger (18–65 years) and geriatric (≥65 years) groups. Primary outcome was a necessity of surgery subsequent to ED. Both groups (patient characteristics, surgical and non-surgical treatment) were compared. Multiple logistic and linear regression models were used to identify the effect of age on the outcomes. A total of 169 patients were included (younger group: 135 patients, geriatric group: 34 patients). The burn size as indicated by %TBSA (24.2 ± 20.4% vs. 26.8 ± 17.1%, p = 0.499) was similar in both groups. The ASA (2.5 ± 1.1 vs. 3.4 ± 1.1, p < 0.001) and ABSI scores (6.1 ± 2.8 vs. 8.6 ± 2.3, p < 0.001) were significantly higher in the geriatric group. The %TBSA treated with ED (5.4 ± 5.0% vs. 4.4 ± 4.3%, p = 0.245) were similar in both groups. The necessity of additional surgical interventions (63.0 % vs. 58.8 %, p = 0.763) and the wound size debrided and grafted (2.9 ± 3.5% vs. 2.2 ± 2.1%; p = 0.301) were similar in both groups. Regression models yielded that age did not have an effect on efficacy of ED. We showed that ED is reliable and safe to use in geriatric patients. Age did not have a significant influence on the surgical outcomes of ED. In both groups, the size of the grafted area was reduced and, in many patients, surgery was avoided completely.

Patient-Reported Outcomes After Reduction Mammoplasty Using BREAST-Q: A Systematic Review and Meta-Analysis. Aesthet Surg J 2023; 43:NP231-NP241. [PMID: 36411260 DOI: 10.1093/asj/sjac293] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Revised: 10/23/2022] [Accepted: 10/25/2022] [Indexed: 11/23/2022] Open
Abstract
BACKGROUND The BREAST-Q questionnaire reduction module is an established tool for outcomes after reduction mammoplasty. OBJECTIVES This systematic review and meta-analysis assess key parameters affecting pre- and postoperative scores, with specific foci on patient characteristics and tissue resection weights. METHODS This study was conducted per PRISMA guidelines. PUBMED (National Institutes of Health; Bethesda, MD), Google Scholar (Google; Mountain View, CA), and Web of Science (Clarivate Analytics; Philadelphia, PA) were searched. All studies published before August 1, 2021, were assessed for eligibility by 2 independent reviewers. Inclusion criteria were prospective or retrospective studies in 6 languages that reported quality of life after reduction mammoplasty employing the BREAST-Q questionnaire reduction module. Quality of included studies was assessed employing the Newcastle-Ottawa-Scale. Analysis was performed per Cochrane Collaboration and the Quality of Reporting of Meta-analyses guidelines. RESULTS A total of 28 papers were included in the systematic review, 13 for preoperative meta-analysis, and 17 for postoperative meta-analysis. Postoperative scores in all 3 quality of life domains (psychosocial, physical, and sexual well-being) and satisfaction with breasts increased significantly after reduction mammoplasty compared with preoperative scores. Satisfaction with breasts showed the greatest improvement, from 22.9 to 73.0. Preoperative scores were lower than normative data, with improvement to comparable scores as the healthy population postoperatively. Improvements in BREAST-Q scores did not correlate with patient comorbidities, complication rates, or amount of breast tissue resected. CONCLUSIONS Reduction mammoplasty provides marked improvement in BREAST-Q patient-reported quality of life as well established in literature. However, these improvements do not correlate with tissue resection weights, warranting further inquiry of insurance-defined resection requirements. LEVEL OF EVIDENCE: 3

Effective or Harmful-Evaluation of Locally Applied Antibiotics on Adipose Tissue during Lipofilling to the Breast-An In Vitro Study. Int J Mol Sci 2023; 24:ijms24032323. [PMID: 36768647 PMCID: PMC9917044 DOI: 10.3390/ijms24032323] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2022] [Revised: 01/19/2023] [Accepted: 01/21/2023] [Indexed: 01/26/2023] Open
Abstract
Lipofilling is a frequently used and safe procedure for breast reconstruction. One of the most feared complications is soft tissue infection following lipofilling. Because of this, some surgeons propose the practice of rinsing fat grafts with antibiotics. This study investigates the effect of antibiotic rinses on fat grafts in an in vitro model. Adipocytes and stem cells were isolated from fat tissue harvested during 24 lipofilling procedures and incubated with different doses of clindamycin or cefazolin. Cell viability, metabolism, proliferation, and differentiation capacities were analyzed by gross morphology, fluorescence staining, -(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazoliumbromid (MTT-), and Glyceraldehyde 3 Phosphate Dehydrogenase (G3PD)-assay as well as reactive oxygen species (ROS)-assay. Cefazolin and clindamycin led to significant reduction of cell viability of adipocytes. High doses of both antibiotics led to a rupture of adipocytes with visible free lipid droplets. Cell metabolism was significantly decreased after incubation with both antibiotics. There was a significant increase in ROS production. Exposure to clindamycin and cefazolin led to morphological changes in stem cells in a dose- and time-dependent manner. Furthermore, differentiation potential was significantly reduced. Antibiotic susceptibility testing, however, showed that low concentrations of antibiotics effectively inhibited bacterial growth in contaminated fat grafts. This study confirms that rinsing fat grafts with clindamycin or cefazolin not only overly prevents infection but also has cytotoxic and metabolic effects on adipocytes. Therefore, based on these results, the routine clinical application in high doses cannot be recommended.

Abstract
We retrospectively compared 64 scaphoid reconstructions in cases that had not undergone previous surgery with 31 cases in which previous surgery had been performed. The characteristics of the groups were similar except that there were more smokers in the group without previous surgery and a more frequent use of vascularized bone grafts in the group with previous surgery. At final follow-up, 66 and 65 months, respectively, after reconstruction, union incidence was 89% and 90%. In patients with previous surgery, grip strength was higher but not when expressed in percent of the contralateral hand. There were no differences in pinch strength, active wrist motion, functional scores, carpal height or scapholunate angle. We conclude that repeat surgery to the scaphoid did not seem to be a major risk factor for the overall outcomes, keeping in mind that a vascularized bone graft was more frequently used for secondary reconstructions.Level of evidence: III.

Oral doxycycline prevents skin-associated adverse effects induced by injectable collagenase in a rodent model of capsular contracture around silicone implants. PLoS One 2022; 17:e0270112. [PMID: 35793344 PMCID: PMC9258873 DOI: 10.1371/journal.pone.0270112] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2021] [Accepted: 06/03/2022] [Indexed: 11/24/2022] Open
Abstract
Background The collagenase of the bacterium Clostridium histolyticum (CCH) is already an established treatment for fibroproliferative diseases like M. Dupuytren and M. Peyronie Although results are comparable to surgical intervention, skin laceration is a severe and relevant side effect. Doxycycline (DOX) recently rose interest as an inhibitor of matrix-metalloproteinases alongside its capabilities of skin accumulation. It therefore might be a potential skin protective agent in the use of CCH. Methods For simulation of a fibroproliferative disease adjacent to the skin, we utilized a rodent model of capsular fibrosis involving silicone implants and subsequent fibrotic capsule formation. For in-vitro studies, fibrotic capsules were excised and incubated with 0.9 mg/ml CCH and four different doses of DOX. For in-vivo experiments, animals received 0.0, 0.3 or 0.9 mg/ml CCH injections into the fibrotic capsules with or without prior oral DOX administration. Outcome analysis included histology, immunohistochemistry, gene expression analysis, chemical collagen and DOX concentration measurements as well as μCT imaging. Results In-vitro, DOX showed a dose-dependent inhibition of CCH activity associated with increasing capsule thickness and collagen density and content. In-vivo, oral DOX administration did neither interfere with capsule formation nor in effectiveness of CCH dissolving fibrotic capsule tissue. However, skin thickness and especially collagen density was significantly higher compared to control groups. This led to a reduced rate of clinical skin lacerations after DOX administration. Conclusion DOX inhibits CCH and accumulates in the skin. Thereby, DOX can effectively reduce skin laceration after CCH treatment.

The modified 5-item frailty index is a predictor of perioperative risk in breast reconstruction: An analysis of 40,415 cases. J Plast Reconstr Aesthet Surg 2022; 75:2941-2954. [PMID: 35599223 DOI: 10.1016/j.bjps.2022.04.035] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2021] [Revised: 02/23/2022] [Accepted: 04/12/2022] [Indexed: 10/18/2022]
Abstract
BACKGROUND The aging population has presented surgeons with new challenges as they increasingly must operate on greater numbers of frail patients. The modified frailty index 5 (mFI-5) is a concise comorbidity-based scale that has been shown to accurately predict adverse surgical outcomes. In this study, we sought to evaluate the ability of the mFI-5 to predict the risk of postoperative outcomes in breast reconstruction patients. METHODS Utilizing the 2015-2019 American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database, we identified 40,415 patients who underwent breast reconstruction, of which 29,562 were implant-based reconstructions and 10,853 were autologous breast reconstructions. Demographic and preoperative variables as well as 30-day postoperative outcomes, including mortality, operation duration, length of hospital stay, medical and surgical complications, and discharge destination, were extracted. RESULTS Increases in the mFI score correlated with higher rates of reoperation (mFI≥3: 13.5% vs. mFI=0: 5.9%), unplanned readmission (mFI≥3: 10.8% vs. mFI=0: 3.6%), surgical (mFI≥3: 12.2% vs. mFI=0: 4.3%) and medical complications (mFI≥3: 6.8% vs. mFI=0: 1.2%), and lower rates of home discharge (mFI≥3: 96% vs. mFI=0: 99.5%). Multivariate analysis to control for confounders verified significantly higher rates of reoperation (OR=0.01, 95%CI 0.005-0.016), unplanned readmission (OR=0.009, 95%CI 0.005-0.014), and occurrence of surgical complications (OR=0.014, 95%CI 0.009-0.019) and medical complications (OR=0.005, 95%CI 0.002-0.008). Stratification by age showed that the mFI-5 was a stronger risk predictor in younger patients who are frail. Stratification by type of reconstruction showed that increased mFI scores significantly correlated with complications in both autologous and implant-based reconstruction, but the correlation was greater in autologous procedures. CONCLUSION The mFI-5 is identified as a powerful risk predictor in breast reconstruction. The application of this easily accessible tool in the preoperative risk stratification of patients undergoing breast reconstruction can enhance treatment planning and support, optimizing patient counseling, informed consent, and decision-making.

Abstract
Microsurgical breast reconstruction demands the highest level of expertise in both reconstructive and aesthetic plastic surgery. Implementation of such a complex surgical procedure is generally associated with a learning curve defined by higher complication rates at the beginning. The aim of this study was to present an approach for teaching deep inferior epigastric artery perforator (DIEP) and transverse upper gracilis (TUG) flap breast reconstruction, which can diminish complications and provide satisfying outcomes from the beginning. DIEP and TUG flap procedures for breast reconstruction were either performed by a senior surgeon (>200 DIEP/TUG, "no-training group"), or taught to one of five trainees (>80 breast surgeries; >50 free flaps) in a step-wise approach. The latter were either performed by the senior surgeon, and a trainee was assisting the surgery ("passive training"); by the trainee, and a senior surgeon was supervising ("active training"); or by the trainee without a senior surgeon ("after training"). Surgeries of each group were analyzed regarding OR-time, complications, and refinement procedures. A total of 95 DIEP and 93 TUG flaps were included into this study. Before the first DIEP/TUG flap without supervision, each trainee underwent a mean of 6.8 DIEP and 7.3 TUG training surgeries (p > 0.05). Outcome measures did not reveal any statistically significant differences (passive training/active training/after training/no-training: OR-time (min): DIEP: 331/351/338/304 (p > 0.05); TUG: 229/214/239/217 (p > 0.05); complications (n): DIEP: 6/13/16/11 (p > 0.05); TUG: 6/19/23/11 (p > 0.05); refinement procedures (n): DIEP:71/63/49/44 (p > 0.05); TUG: 65/41/36/56 (p > 0.05)), indicating safe and secure implementation of this step-wise training approach for microsurgical breast reconstruction in both aesthetic and reconstructive measures. Of note, despite being a perforator flap, DIEP flap required no more training than TUG flap, highlighting the importance of flap inset at the recipient site.

Abstract
BACKGROUND Metabolic syndrome (MetS) can predispose patients to poorer surgical outcomes. In this study, we sought to evaluate the impact of MetS on the postoperative outcomes of head and neck microvascular reconstruction. METHODS Review of the 2015-2019 NSQIP database identified 5,323 cases of microvascular reconstruction, of which 3,809 were head and neck cases. Of the included patients, 184 had MetS and 3625 did not. The groups were compared in terms of demographics and comorbidities. Postoperative outcomes assessed included mortality, average operative time and length of hospital stay, surgical and medical complications, and nonhome discharge. RESULTS The MetS group had higher rates of medical complications (p<0.0001), sepsis (p=0.02), septic shock (p=0.01), and skilled care-discharge (p=0.0004). Analysis by flap type revealed that MetS patients receiving free skin flaps experienced higher rates of organ space infection (p=0.02), sepsis (p<0.0001), and lower home-discharge (p=0.01). In the free muscle group, superficial incisional infection (p=0.04), UTI (p=0.02), and septic shock (p=0.01) were higher in MetS patients. Stratification by surgical site showed that the occurrence of sepsis was significantly higher in the patients receiving microvascular flap reconstruction of the larynx (p=0.04) or tongue(p=0.03). Stratification of the MetS patients according to treatment for diabetes showed that patients receiving insulin experienced a higher rate of superficial incisional infection (p=0.04). A multivariate analysis verified significantly higher rates of medical complications (p<0.0001), sepsis (p=0.03) and septic shock (p=0.01) in the MetS group. CONCLUSION Patients with MetS undergoing head and neck microvascular reconstruction are at increased risk of postoperative medical complications, including sepsis and septic shock, and are more likely to be discharged to a skilled care facility. Surgical outcomes were found to depend on the type of flap and site of surgery.

Abstract
BACKGROUND Tenolysis is an established treatment for flexor tendon adhesions at the hand. Concomitant finger nerve injuries with incomplete reinnervation may negatively influence outcomes. This study investigates the impact of finger nerve injuries on outcomes of flexor tendon tenolysis. METHODS A retrospective pair-matched study was conducted, including patients undergoing tenolysis for flexor tendon adhesion after primary repair of isolated superficial and deep flexor tendon injury and both finger nerves (test group [TG]). These were compared with patients (control group [CG]) with similar injuries without affection of nerves and pair-matched in age, zone of injury and follow-up. Patients' demographics, finger sensitivity, total active range of motion (TAM) before and after tenolysis and complications were retrieved. RESULTS For both study groups, 10 patients each were included in this study. There were no significant differences regarding patients' demographics and follow-up. Mean follow-up was 37 (CG) and 41 (TG) months. Total active range of motion was preoperatively 81 ± 47° (CG) and 68 ± 54° (TG) and reached postoperatively 125 ± 57° (CG) and 79 ± 43° (TG). Hence, TAM improvement was significantly higher in patients without nerve damage (58 ± 16 vs 21 ± 11%; P > 0.05). Tendon ruptures occurred significantly more frequent in patients with nerve injury (n = 0.4 ± 0.52) compared with patients of the CG (n = 0; P < 0.05). CONCLUSIONS This study shows that finger nerve injury with incomplete recovery after combined flexor tendon and nerve injuries of the finger negatively influences the outcomes of flexor tendon tenolysis.

Abstract
BACKGROUND The modified frailty index 5 (mFI-5)-a scale based on the five variables diabetes, hypertension, chronic obstructive pulmonary disease, congestive heart failure, and functional dependency-has been shown to be a valid predictor of surgical outcomes. In this study we sought to evaluate the ability of the mFI-5 to predict the postoperative outcomes of head and neck microvascular reconstruction. METHODS Review of the 2015-2019 American College of Surgeons, National Surgical Quality Improvement Program (ACS NSQIP) database identified 5323 cases of microvascular reconstruction, of which 3795 were head and neck cases that provided parameters necessary to calculate the mFI-5. The groups were compared in terms of demographics and comorbidities. Post-operative outcomes assessed included mortality, average operative time and length of hospital stay, surgical and medical complications, and non-home discharge. RESULTS Increases in the mFI were associated with longer hospitalization periods (10.5 ± 7.5 days in mFI 0 vs 14.9 ± 15.4 in mFI ≥ 3; p < 0.0001) higher rates of mortality (1% in mFI 0 vs 3.1% in mFI ≥ 3; p = 0.02), reoperation (15.4% in mFI 0 vs 17.2% in mFI ≥ 3; p = 0.002) and unplanned readmission (7.6% in mFI 0 vs 18.8% in mFI ≥ 3; p = 0.001). Rates of any complications (p < 0.0001), as well as surgical (p < 0.002) and medical (p < 0.0001) complications specifically were higher with greater mFI scores. Higher mFI scores also predicted decreased home discharge (p < 0.0001). Differences remained significant on multivariate analysis and subgroup analysis by age. CONCLUSION The mFI-5 is a significant predictor of risk in microvascular head and neck reconstruction. Subgroup analysis by age highlights that the tool can help identify younger patients who are frail and hence at risk. Through appropriate pre-operative identification of frail patients surgeons can prospectively modify their operative and discharge planning as well as post-operative support.

Abstract
BACKGROUND Irradiation therapy limits the utilization of silicone implants for breast reconstruction due to a significant risk for capsular contracture. The injection of the collagenase of the bacterium Clostridium histolyticum (CCH) might trivialize this risk by providing a minimal-invasive treatment option by capsular contracture degradation. However, efficacy in degrading breast implant capsules induced by fractionated irradiation remains unclear. METHODS Twenty-four rats in three groups received miniature silicone implants in a submuscular pocket. After 3D dose calculation and treatment field definition, rats of two groups underwent fractionated radiotherapy (6 × 8 Gy) using a linear accelerator. A third group served as control. On day 120, one irradiated group received injections of 0.3 mg/ml collagenase. Administration of plain solvent solution served as control in the two other groups. Outcome parameters included CT-imaging, histology, vessel wall analysis, immunohistochemistry, chemical collagen quantification and gene expression analysis. RESULTS Fractioned irradiation leads to a significant increase in collagen deposition around silicone implants with higher capsule thickness and collagen density when comparing all groups. Additionally, significant alterations of collagen fiber deposition were evident. Vessel wall thickness was significantly increased after radiotherapy. The injection of collagenase led to a significant reduction of capsule thickness, collagen density and content. However, the collagenase application induced a significant overexpression of TGFβ1. No side effects were monitored. CONCLUSIONS The CCH proved to be a safe and effective approach to degrade capsule tissue induced by fractionated irradiation in an animal model. This may pave its way for clinical application in implant-based breast reconstruction patients.

Abstract
INTRODUCTION Enzymatic debridement (ED) has become a reliable tool for eschar removal. Although ED application is simple, wound bed evaluation and therapy decision post-intervention are prone to subjectivity and failure. Experience in ED might be the key, but this has not been proven yet. Aim of this study was to assess interrater reliability (IR) in post-intervention wound bed evaluation and therapy decision as well as the impact of experience. In addition, the authors introduce video assessment as a valuable tool for post-ED decision making and education. MATERIAL AND METHODS A video-based survey was conducted among physicians with various experience in ED. The survey involved multiple choice and 5-point Likert scale questions about professional status, experience in ED, confidence in post-ED wound bed evaluation and therapy decision. Subsequently, videos of 15 mixed pattern to full thickness burns immediately after removal of the enzyme complex were demonstrated. Participants were asked for evaluation of each burn wound, including bleeding pattern and consequent therapy decision. IR ≥80% was considered as a consensus. Responses were stratified according to participants' experience in applying ED (<10; 10-19; 20-49; ≥50 applications). IR was assessed by Chi^2-test (raw agreement (RA); ≥80% was considered as a consensus) and by Krippendorff's Alpha-test. In addition, expert consensus for therapy decision was compared to the actual clinical course of each shown patient. Last, participants were asked for their opinion on video as an assessment tool for post-ED wound bed evaluation, decision making and training. RESULTS 31 physicians from 11 burn centers participated in the survey. Overall consensus (RA≥80%) in post-ED wound bed evaluation and therapy decision was achieved in 20 and 40%, respectively. Krippendorff's Alpha are given by 0.32 (95% CI: 0.15,0.49) and 0.31 (95% CI: 0.16,0.47), respectively. Subgroup analysis revealed that physicians with high experience in ED achieved significantly more consensus in post-intervention wound bed evaluation and therapy decision compared to physicians with moderate experience (60% vs. 13.3%; p=0.02 and 86.7 vs. 33.3%; p=0.04, respectively). Video analysis was considered a feasible (90.3%) and beneficial (93.5%) tool for post-intervention wound bed evaluation and therapy decision as well as useful for training purposes (100%). CONCLUSION Reliability of wound bed evaluation and therapy decision after ED depends on the experience of the rating physician. Video analysis is deemed to be a valuable tool for ED evaluation, decision making and user training.

ICF-based multidisciplinary rehabilitation program for complex regional pain syndrome of the hand: efficacy, long-term outcomes, and impact of therapy duration. BMC Surg 2020; 20:306. [PMID: 33256710 PMCID: PMC7708143 DOI: 10.1186/s12893-020-00982-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2020] [Accepted: 11/23/2020] [Indexed: 11/24/2022] Open
Abstract
Background Complex regional pain syndrome (CRPS) is a rare but feared complication in hand surgery. Although multimodal therapy concepts are recommended, there is only low evidence on efficacy of such approaches. Furthermore, recommendations regarding therapy duration are lacking. Aim of this study was to validate the efficacy of an International Classification of Functioning, Disability and Health (ICF)-based multidisciplinary rehabilitation concept for treatment of CRPS of the hand and to find correlations between therapy duration and outcome measures. Methods Patients with CRPS of the hand after occupational trauma that underwent an ICF-based rehabilitation program between 2010 and 2014 were included in this retrospective study. Besides demographic data, outcomes included pain (VAS), range of motion assessed by fingertip-to-palm-distance (PTPD) and fingernail-to-table-distance (FTTD) as well as strength in grip, 3-point pinch and lateral pinch. All measures were gathered at admission to and discharge from inpatient rehabilitation therapy as well as at follow-up. Statistical analysis included paired t-test, ANOVA and Pearson's correlation analysis. Results Eighty-nine patients with a mean age of 45 years were included in this study. Duration of rehabilitation therapy was 53 days on average. All outcomes improved significantly during rehabilitation therapy. Pain decreased from 6.4 to 2.2. PTPD of digit 2 to 5 improved from 2.5, 2.8, 2.6, and 2.3 cm to 1.3, 1.4, 1.2, and 1.1 cm, respectively. FTTD of digit 2 to 5 decreased from 1.5, 1.7, 1.5, and 1.6 cm to 0.6, 0.8, 0.7, and 0.7 cm, respectively. Strength ameliorated from 9.5, 3.7, 2.7 kg to 17.9, 5.6, 5.0 kg in grip, lateral pinch, and 3-point pinch, respectively. Improvement in range of motion significantly correlated with therapy duration. 54% of patients participated at follow-up after a mean of 7.5 months. Outcome measures at follow-up remained stable compared to discharge values without significant differences. Conclusion The ICF-based rehabilitation concept is a reliable and durable treatment option for CRPS of the hand. Range of motion improved continuously with therapy duration and thus may serve as an indicator for optimum length of therapy.

Radial collateral ligament repair of the thumb: long-term outcomes and predictive factors of postoperative deficits. Arch Orthop Trauma Surg 2020; 140:1293-1299. [PMID: 32500203 DOI: 10.1007/s00402-020-03509-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/24/2020] [Accepted: 05/31/2020] [Indexed: 10/24/2022]
Abstract
BACKGROUND The thumb's radial collateral ligament (RCL) plays an important role in stabilizing the first metacarpophalangeal joint (MCP-1). RCL injuries are rare and treatment recommendations are inconsistent in the current literature. The aim of this study was to report on long-term outcomes following surgical repair of thumb RCL tear and to identify prognostic risk factors for treatment failure. METHODS Patients with RCL tear from 10/1998 to 10/2019 were included in the present retrospective single center cohort study. In follow-up visits, participants were assessed regarding pain, range of motion and strength as well as with disability of shoulder, arm and hands (DASH), and the Short-Form 36 (SF36) questionnaires. Finally, predictive factors of postoperative deficits were identified. RESULTS 43 patients fulfilled inclusion criteria. Median age was 43.5 years (range 18-80 years). The most frequent mechanism of injury was a fall or impact. Bony avulsions were identified in 46.5% (20/43). Time from injury to surgery was 12 days (0-276 days). One Stener-like lesion was observed intraoperatively among our patients. After surgical repair, the MCP-1 joint was stable in every patient. Mean time to follow-up was 5.3 years (1 month to 17 years). Persistency of pain in the MCP-1 joint was reported by 11 patients. Postoperative averaged score was 3.75 on DASH and 44.96 on SF36, respectively. The average grip and pinch strength was 32.7 kg and 8.37 kg, respectively. Predictive factors of postoperative deficits were delay of surgery of > 3 weeks (OR 10.72, p 0.017) and palmar subluxation prior to surgery (OR 8.86, p 0.019). CONCLUSION Long-term follow-up has proven that surgical repair of RCL enables the patient to regain adequate stability and strength of the MCP-1 joint and minimizes disability. Predictive risk factors of pain persistency after surgery are surgical delay and palmar subluxation of the MCP-1 joint.

Negative pressure wound therapy with instillation and dwell time (NPWTi-d) with V. A. C. VeraFlo in traumatic, surgical, and chronic wounds-A helpful tool for decontamination and to prepare successful reconstruction. Int Wound J 2020; 17:1740-1749. [PMID: 32716140 PMCID: PMC7948994 DOI: 10.1111/iwj.13462] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2020] [Revised: 06/24/2020] [Accepted: 06/28/2020] [Indexed: 01/10/2023] Open
Abstract
For nearly two decades, Negative Pressure Wound Therapy (NPWT) has been used for temporary wound coverage as well as wound bed preparation. The addition of instillation and dwell time as an adjunct to NPWT (NPWTi‐d) enables wound bed cleaning and improved wound bed granulation. Thirty patients with different types of colonised wounds (traumatic, surgical, and chronic) were treated with NPWTi‐d using saline for instillation. Patient data, microbiological data and wound characteristics were collected and analysed. Endpoints were bacterial decontamination (count and type), effect on wound bed granulation, and successful reconstruction. Additionally, subgroup analyses for traumatic, surgical, and chronic wounds as well as patients pretreated with conventional NPWT or isolated gram‐positive or negative germs were performed. NPWTi‐d was applied on average for 13 days with a total hospitalisation time of 51 days. After NPWTi‐d, decontaminated wounds were detected in 23% of cases. The number of different bacteria as well as bacterial count could be significantly reduced from 2.38 to 1.16 and 3.9 to 1.3, respectively. This was similar for all subgroups except surgical wounds, in which NPWTi‐d did not lead to a significant reduction of the bacterial count. NPWTi‐d resulted in a significant stimulation of granulation tissue. Successful reconstruction was achieved in 90% of cases. NPWTi‐d enabled wound pre‐conditioning by powerfully reducing or decontaminating the bacterial load and spectrum in most of the wounds. The wound bed integrity was re‐established to prepare successful reconstruction.
