Background: The focus of research and management of Dupuytren's disease (DD) is shifting from relieving symptoms in the later stages of disease towards the prevention of contractures. Treatment services might likewise shift towards primary care. Studying characteristics of DD patients who seek medical care for the first time, may identify a symptomatic target group for early DD treatments. We present the first study that estimates the incidence and prevalence of DD in primary care by applying a text-mining algorithm to registration data., Methods: This is a population-based cohort study using electronic health records from Dutch general practices involved in a regional research network. Descriptive statistics were used to describe sex, age, comorbidities and lifestyle factors, the latter two were identified via International Classification of Primary Care (ICPC) codes. Incidence rate was calculated as number of patients with a first contact for DD/1000 person years for the years 2017-2021, point prevalence as the percentage of patients with a contact for DD in 2021. DD contacts were identified using a text-mining algorithm., Results: The incidence ranged between 1.41 and 1.72/1000 person years and the overall prevalence was 1.99%. Incidence and prevalence are higher among males and increase with age, peaking between 61 and 80 years., Conclusions: Our results of prevalence and incidence of DD in primary care give an insight into the relevant population of patients with symptomatic DD that might be the future target group for potential disease controlling treatments.

Previous studies suggest that Dupuytren's disease is associated with increased mortality, but most studies failed to account for important confounders. In this population-based cohort study, general practitioners' (GP) data were linked to Statistics Netherlands to register all-cause and disease-specific mortality. Patients with Dupuytren's disease were identified using the corresponding diagnosis code and assessing free-text fields from GP consultations. Multiple imputations were performed to estimate missing values of covariates, followed by 1:7 propensity score matching to balance cases with controls on confounding factors. A frailty proportional hazard model was used to compare mortality between both groups. Out of 209,966 individuals, 2561 patients with Dupuytren's disease were identified and matched to at least four controls. After a median follow-up of 5 years, mortality was found to be actually reduced in patients with Dupuytren's disease. There was no difference in mortality secondary to cancer or cardiovascular disease. Future studies with longer average follow-up using longitudinal data should clarify these associations in the longer term.

Objective(s): To explore learning effects when applying the clinician-graded electronic facial function scale (eFACE) and the Sunnybrook Facial Grading System (Sunnybrook)., Methods: Surgeons, facial rehabilitation therapists, and medical students were randomly allocated to the eFACE (n = 7) or Sunnybrook (n = 6) and graded 60 videos (Massachusetts Eye and Ear Infirmary open-source standard set); 10 persons with normal facial function and 50 patients with a wide variation of facial palsy severity. Participants received an introduction and individual feedback after each set of 10 videos. Scores were compared to the reference score provided with the set. Multilevel analysis was performed to analyze learning effect., Results: A learning effect was only found for the eFACE, with significant difference scores in set 1 and 2 compared to set 6, and no significant difference scores in the following sets. The difference score was associated with the reference score (severity of facial palsy) for eFACE (β = -0.19; SE = 0.04; p < 0.001) and Sunnybrook (β = -0.15; SE = 0.04; p < 0.001). Age of participants was also associated with the difference score in the eFACE group (β = 0.18; SE = 0.03; p < 0.001). No differences in scores were found between groups of participants., Conclusion: The eFACE showed a learning effect of feedback while the Sunnybrook did not., Level of Evidence: NA Laryngoscope, 134:3105-3111, 2024., (© 2024 The Authors.

Flap necrosis continues to occur in skin free flap autologous breast reconstruction. Therefore, we investigated the benefits of indocyanine green angiography (ICGA) using quantitative parameters for the objective, perioperative evaluation of flap perfusion. In addition, we investigated the feasibility of hyperspectral (HSI) and thermal imaging (TI) for postoperative flap monitoring. A single-center, prospective observational study was performed on 15 patients who underwent deep inferior epigastric perforator (DIEP) flap breast reconstruction (n=21). DIEP-flap perfusion was evaluated using ICGA, HSI, and TI using a standardized imaging protocol. The ICGA perfusion curves and derived parameters, HSI extracted oxyhemoglobin (oxyHb) and deoxyhemoglobin (deoxyHb) values, and flap temperatures from TI were analyzed and correlated to the clinical outcomes. Post-hoc quantitative analysis of intraoperatively collected data of ICGA application accurately distinguished between adequately and insufficiently perfused DIEP flaps. ICG perfusion curves identified the lack of arterial inflow (n=2) and occlusion of the venous outflow (n=1). In addition, a postoperatively detected partial flap epidermolysis could have been predicted based on intraoperative quantitative ICGA data. During postoperative monitoring, HSI was used to identify impaired perfusion areas within the DIEP flap based on deoxyHb levels. The results of this study showed a limited added value of TI. Quantitative, post-hoc analysis of ICGA data produced objective and reproducible parameters that enabled the intraoperative detection of arterial and venous congested DIEP flaps. HSI appeared to be a promising technique for postoperative flap perfusion assessment. A diagnostic accuracy study is needed to investigate ICGA and HSI parameters in real-time and demonstrate their clinical benefit., Competing Interests: Paul M.N.

Background: Dupuytren disease (DD) is a common complex trait, with varying severity and incompletely understood cause. Genome-wide association studies (GWAS) have identified risk loci. In this article, we examine whether genetic risk profiles of DD in patients are associated with clinical variation and disease severity and with patient genetic risk profiles of genetically correlated traits, including body mass index (BMI), triglycerides, high-density lipoproteins, type 2 diabetes mellitus, and endophenotypes fasting glucose and glycated hemoglobin., Methods: The authors used a well-characterized cohort of 1461 DD patients with available phenotypic and genetic data. Phenotype data include age at onset, recurrence, and family history of disease. Polygenic risk scores (PRSs) of DD, BMI, triglycerides, high-density lipoprotein, type 2 diabetes, fasting glucose, and hemoglobin A1c using various significance thresholds were calculated with PRSice using the most recent GWAS summary statistics. Control data from LifeLines were used to determine P value cutoffs for PRS generation explaining most variance., Results: The PRS for DD was significantly associated with a positive family history for DD, age at onset, disease onset before the age of 50, and recurrence. We also found a significant negative correlation between the PRSs for DD and BMI., Conclusions: Although GWAS studies of DD are designed to identify genetic risk factors distinguishing case/control status, we show that the genetic risk profile for DD also explains part of its clinical variation and disease severity. The PRS may therefore aid in accurate prognostication, choosing initial treatment and in personalized medicine in the future., Clinical Question/level of Evidence: Risk, III., (Copyright © 2023 The Authors.

Purpose: Crown-like structures (CLS) in breast adipose tissue are associated with inflammation and a potential factor in breast cancer behaviour. Whether this effect varies between breast cancer subtypes and is influenced by BMI and BRCA mutation status is presently unknown. Therefore, we compared CLS presence between adipose tissue of healthy controls, BRCA1/2 gene mutation carriers and breast cancer patients, and assessed the relation of CLS with clinical outcome in breast cancer patients., Methods: Immunohistochemical staining for CD68 was performed on breast adipose tissue sections of 48 healthy controls, 78 BRCA1/2 gene mutation carriers and 259 breast cancer patients. CLS presence and index (CLS/cm 2 ) were correlated with BMI, BRCA status, tumour presence, intrinsic tumour subtype and tumour characteristics. Associations with clinical outcome were assessed., Results: CLS were more often present in breast cancer patients compared to BRCA carriers and healthy controls. CLS presence was associated with the presence of breast cancer and high BMI. CLS were more often present in Luminal-B-like tumours compared to the other subtypes. No correlations between CLS and BRCA status or age was found. In TNBC, CLS were related to lymphovascular invasion. No association with survival was found., Conclusion: In conclusion, CLS were more frequently present in breast adipose tissue of breast cancer patients compared to BRCA1/2 gene mutation carriers and healthy controls. Furthermore, our study provides evidence of the association between obesity and presence of CLS. The prognostic significance and impact on clinical outcome of differences in CLS numbers should be further assessed in prospective studies., (© 2023.

Background: Patients with Dupuytren's disease (DD) are mostly surgically treated by percutaneous needle fasciotomy (PNF) or limited fasciectomy (LF), but data on time intervals to retreatment is lacking. We aimed to estimate the risk of retreatment within certain time periods after treatment with PNF and LF., Methods: We used data of participants of a cohort study on the course of DD who were treated only with PNF or LF. Our primary outcome measure was time to retreatment of DD. We included sex, age at first treatment and having a first degree relative with DD as confounders in our analysis. We applied a bivariate gamma frailty model to estimate the risk of retreatment within 1,3,5, 10 and 20 years after treatment with PNF and LF., Results: The time to retreatment was significantly shorter after treatment with PNF than after LF (Wald test 7.56, p<0.001). The estimated 10-year risk of retreatment for men who underwent their first treatment at a younger age and with a first degree relative with DD was 97% after PNF and 32% after LF. The estimated 10-year risk for women who underwent their first treatment at an older age without a first degree relative with DD was 20% after PNF and 6% after LF., Conclusions: Our results show that the patients treated with PNF have a higher risk of retreatment. The results of this study could contribute to individualized information on the treatment durability in the future, which would improve patient counseling about the expected retreatment needs., Competing Interests: Conflicts of interest and financial disclosure: PW was member of a Safety and Efficacy Review Board and is Data management committee member for Fidia ltd, Milan Italy.

Dupuytren's disease (DD) is a highly heritable fibrotic disorder of the hand with incompletely understood etiology. A number of genetic loci, including Wnt signaling members, have been previously identified. Our overall aim was to identify novel genetic loci, to prioritize genes within the loci for functional studies, and to assess genetic correlation with associated disorders. We performed a meta-analysis of six DD genome-wide association studies from three European countries and extensive bioinformatic follow-up analyses. Leveraging 11,320 cases and 47,023 controls, we identified 85 genome-wide significant single nucleotide polymorphisms in 56 loci, of which 11 were novel, explaining 13.3-38.1% of disease variance. Gene prioritization implicated the Hedgehog and Notch signaling pathways. We also identified a significant genetic correlation with frozen shoulder. The pathways identified highlight the potential for new therapeutic targets and provide a basis for additional mechanistic studies for a common disorder that can severely impact hand function., (© 2024.

Background: The shift of focus towards disease-controlling treatments to prevent DD progression at an early stage underlines the need for objective and reliable measurements that can monitor and predict the course of disease. Ultrasound has been studied as a potential tool for this purpose. This study examined to what extent echogenicity of early DD nodules predicts clinical progression., Methods: Sonographic assessments of Dupuytren's nodules were performed by the same observer on 151 participants as part of an ongoing prospective cohort study on the course of DD. Echogenicity was assessed by determining the greyness of a nodule relative to the surrounding tissue, using ImageJ software. Progression of disease was defined as 1) an increase in total passive extension deficit (TPED) of ≥15 degrees and 2) surgical intervention of the examined ray, both occurring after the sonographic assessment. The associations between echogenicity and time to progression were estimated using Cox-regression models., Results: The association between echogenicity and time to TPED progression showed that for every additional decrease of 1% in relative greyness (darker image) of a nodule, the risk of TPED progression during follow-up increases by 3.4% (hazard ratio [HR] = 0.966, 95% confidence interval [CI]: 0.935-0.966). Similarly, echogenicity was also associated with time to surgical intervention (HR = 0.967, 95% CI: 0.938-0.997), which indicates a higher risk for surgery during follow-up for darker nodules., Conclusions: These results suggest that echogenicity is predictive of the prognosis of the early stages of DD and might potentially be used as a prognostic imaging biomarker in the future., Competing Interests: Declaration of Competing Interest PW was member of a Safety and Efficacy Review Board of Fidia ltd, Milan, Italy.

Background: Web-based patient-reported outcome measures (PROMs) could help surgeons remotely assess the need for examination and subsequent treatment of patients with Dupuytren disease (DD). The authors studied whether the Unité Rhumatologique des Affections de la Main (URAM) and the Michigan Hand Questionnaire (MHQ) could predict DD treatment., Methods: In this prospective cohort study, the authors compared MHQ and URAM scores of treated patients with those of untreated patients. For the treatment group, the authors selected a score closest to 1 year before treatment. For controls, the authors randomly selected a score. The authors also tested the predictive value of a 1-year change score between 15 months and 6 weeks before treatment. The primary outcome measure was DD treatment. The predictive value was determined using the area under the curve (AUC). An AUC greater than 0.70 was considered good predictive ability; 0.70 to 0.50, poor predictive ability; and less than 0.50, no predictive ability., Results: The authors included 141 patients for the MHQ analysis and 145 patients for the URAM analysis. The AUC of the MHQ and URAM scores measured 1 year before treatment were 0.80 (95% CI, 0.71 to 0.88) and 0.75 (95% CI, 0.68 to 0.82), respectively. The 1-year change score resulted in an AUC less than 0.60 for both questionnaires., Conclusions: The results show that both the MHQ and URAM score measured around 1 year before treatment can predict treatment for DD. If future studies show that telemonitoring of patients with DD with PROMs is also cost-effective, web-based PROMs could optimize patient care and effectiveness of DD treatment., Clinical Question/level of Evidence: Risk, III., (Copyright © 2023 The Authors.

Background: Evidence for effectiveness of radiotherapy for Ledderhose disease was demonstrated in the LedRad-study. However, the health economic impact of Ledderhose disease is unclear. Therefore, an economic evaluation alongside the LedRad-study was planned., Methods: The economic evaluation was performed as a cost-effectiveness and cost-utility analysis from the societal perspective. Primary outcome parameters were pain burden and Quality Adjusted Life Years (QALY), until 12 months after the end of treatment. Secondary analyses were performed with outcomes until 18 months. Incremental cost-effectiveness (ICER) and cost-utility ratios (ICUR) were calculated to express costs per unit improvement in pain burden and costs per QALY gained, for radiotherapy compared to sham-radiotherapy. Bootstrap replication was used to assess uncertainty surrounding the ratios and to construct cost-effectiveness acceptability curves for QALY gain., Results: Previous analysis showed a statistically significant improvement in pain- and QoL scores in favour of radiotherapy at 12 and 18 months. At these timepoints and excluding treatment costs, cumulative total costs were considerably lower in the radiotherapy group. The ICER until 12 months after treatment was 4987 euro per unit of pain burden reduction. The ICUR was 14249 euro per QALY gained. Most of the bootstrap replications were in the upper right quadrant, indicating that health gain can be achieved at higher costs. At increasing levels of willingness to pay for a gain in QALY, the probability of cost-utility gradually increased to approximately 85%., Conclusions: In patients with symptomatic Ledderhose disease, radiotherapy, at a moderate threshold for willingness to pay, is cost-effective in terms of QoL gain., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: P.M.N.

Background: The aim of this prospective multicenter study was to evaluate whether autologous breast reconstruction (BR) leads to lower short-term quality of life (QoL) compared with alloplastic BR, due to the more physically demanding surgery and increased risk of severe complications of autologous BR., Methods: Changes in QoL after BR were measured in this prospective multicenter study using the BREAST-Q questionnaire, which was administered preoperatively and at 6 weeks and 6 months postoperatively. Characteristics and complications, classified according to Clavien-Dindo, were compared between alloplastic and autologous groups. Profile plots and generalized linear regression models were constructed to analyze the BREAST-Q subscales over time for both BR groups., Results: Preoperatively, women undergoing autologous BR scored lower on all BREAST-Q scales compared with women undergoing alloplastic BR, regardless of whether they underwent immediate or delayed BR. Women undergoing autologous BR scored higher at 6 weeks and 6 months postoperatively on the Satisfaction with Breasts ( P = 0.001), Psychosocial Well-Being ( P = 0.024), and Sexual Well-Being ( P = 0.007) subscales. Postoperative Physical Well-Being: Chest score was similar between the groups ( P = 0.533). Clavien-Dindo grade III or higher complications occurred more often among women in the autologous group (27% versus 12%, P = 0.042). Complications were not associated with worse BREAST-Q scores on any of the subscales., Conclusions: In contrast to the authors' expectations, and despite the higher incidence of severe complications and lower preoperative breast satisfaction and QoL scores, women undergoing autologous BR had higher levels of breast satisfaction and psychosocial and sexual well-being, both at 6 weeks and 6 months after BR, compared with women undergoing alloplastic BR., Clinical Question/level of Evidence: Therapeutic, II., (Copyright © 2023 The Authors.

The aim of this double anonymized, randomized controlled trial was to determine whether total joint arthroplasty has superior outcomes than trapeziectomy 1 year after surgery for trapeziometacarpal osteoarthritis. A total of 62 women aged 40 years and older, scheduled for surgery for stage II or III osteoarthritis of the trapeziometacarpal joint, were included and randomized to trapeziectomy or total joint arthroplasty. The primary outcome was the total score of the Michigan Hand Outcomes Questionnaire. Secondary outcomes were the Michigan Hand Outcomes Questionnaire subscale scores, Disability of the Arm, Shoulder and Hand Questionnaire, active range of motion, strength, return to work, patient satisfaction and complications. Data were collected at baseline and at 3 and 12 months. At 1 year, we found no superiority of total joint arthroplasty over trapeziectomy regarding the total score of the Michigan Hand Outcomes Questionnaire. The total joint arthroplasty did show a significant advantage in strength and range of motion.

Background: Plantar pressure distribution during walking in patients with painful Ledderhose disease is unknown., Research Question: Do patients with painful Ledderhose disease have an altered plantar pressure distribution during walking compared to individuals without foot pathologies? It was hypothesized that plantar pressure is shifted away from the painful nodules., Methods: Pedobarography data of 41 patients with painful Ledderhose disease (cases, mean age: 54.2 ± 10.4 years) was collected and compared to pedobarography data from 41 individuals without foot pathologies (controls, mean age: 21.7 ± 2.0 years). Peak Pressure (PP), Maximum Mean Pressure (MMP) and Force-Time Integral (FTI) were calculated for eight regions (heel, medial midfoot, lateral midfoot, medial forefoot, central forefoot, lateral forefoot, hallux and other toes) under the soles of the feet. Differences between cases and controls were calculated and analysed by means of linear (mixed models) regression., Results: Proportional differences in PP, MMP and FTI showed increased values for the cases compared to the controls, especially in the heel, hallux and other toes regions, and decreased values in the medial- and lateral midfoot regions. In naïve regression analysis, being a patient was a predictor for increased- and decreased values for PP, MMP and FTI for several regions. When dependencies in the data were taken into account with linear mixed-model regression analysis, the increased- and decreased values for the patients were most prevalent for FTI at the heel, medial midfoot, hallux and other toes regions., Significance: In patients with painful Ledderhose disease, during walking, a shift of pressure was found towards the proximal and distal foot regions, while offloading the midfoot regions., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: P.M.N.

Background and Purpose: Radiotherapy is considered a treatment option for Ledderhose disease. However, its benefits have never been confirmed in a randomised controlled trial. Therefore, the LedRad-study was conducted., Materials and Methods: The LedRad-study is a prospective multicentre randomised double-blind phase three trial. Patients were randomised to sham-radiotherapy (placebo) or radiotherapy. The primary endpoint was pain reduction at 12 months after treatment, measured with the Numeric Rating Scale (NRS). Secondary endpoints were pain reduction at 6 and 18 months after treatment, quality of life (QoL), walking abilities and toxicity., Results: A total of 84 patients were enrolled. At 12 and 18 months, patients in the radiotherapy group had a lower mean pain score compared to patients in the sham-radiotherapy group (2.5 versus 3.6 (p = 0.03) and 2.1 versus 3.4 (p = 0.008), respectively). Pain relief at 12 months was 74% in the radiotherapy group and 56% in the sham-radiotherapy group (p = 0.002). Multilevel testing for QoL scores showed higher QoL scores in the radiotherapy group compared to the sham-radiotherapy group (p < 0.001). Moreover, patients in the radiotherapy group had a higher mean walking speed and step rate with barefoot speed walking (p = 0.02). Erythema, skin dryness, burning sensations and increased pain were the most frequently reported side effects. These side effects were generally graded as mild (95%) and the majority (87%) were resolved at 18 months follow-up., Conclusion: Radiotherapy for symptomatic Ledderhose disease is an effective treatment resulting in a significant pain reduction, improvement of QoL scores and bare feet walking abilities, in comparison to sham-radiotherapy., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: P.M.N.

Background: The aim of this study was to evaluate the long-term patient satisfaction and quality of life 9 to 13 years after autologous versus alloplastic breast reconstruction and compare the data to those of an earlier study., Methods: This is a 9-year follow-up study of 92 women who underwent breast reconstruction (47 autologous and 45 alloplastic) between 2006 and 2010 and filled out the BREAST-Q questionnaire in 2010. Changes in BREAST-Q scores were analyzed by using a change score from baseline (2010) to follow-up (2019), which was presented by a mean change score with 95% confidence intervals. Linear regression analyses were performed to test which patient characteristics were related to the BREAST-Q change scores., Results: The response rate at follow-up was 60% (25 autologous and 30 alloplastic). Responders at follow-up had a lower body mass index and had less frequently undergone unilateral breast reconstruction compared to the nonresponders. Women undergoing both autologous and alloplastic breast reconstruction had significantly decreased satisfaction with breasts (-4 points), satisfaction with outcome (-8 points), and satisfaction with nipples (-20 points) over time. None of the patient characteristics, including reconstruction technique, were related to the BREAST-Q change scores., Conclusions: Satisfaction with breasts, satisfaction with outcome, and satisfaction with nipples decreased slightly over time for women undergoing alloplastic and autologous breast reconstruction. Women undergoing autologous breast reconstruction seemed to remain more satisfied with their breasts 9 to 13 years after breast reconstruction compared to women undergoing alloplastic breast reconstruction. Because of the small sample size, conclusions should be carefully drawn. However, the results were in line with the expectations based on previous literature., Competing Interests: Disclosure:The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article ., (Copyright © 2022 The Authors.

Objectives: Dupuytren's disease (DD) is a fibroproliferative disorder of the hands, characterised by the development of fibrous nodules and cords that may cause disabling contractures of the fingers. The role of manual work exposure in the aetiology of DD is controversial. We investigated whether current occupational exposure to manual work is associated with DD, and if there is a dose-response relationship., Methods: In this population-based cohort analysis, we used data from the UK Biobank cohort. Our primary outcome was the presence of DD. The exposure of interest was manual work, measured for each participant in two different ways to allow two independent analyses to be undertaken: (1) the current manual work status of the occupation at the time of recruitment, and (2) a cumulative manual work exposure score, calculated based on the occupational history. We performed propensity score matching and applied a logistic regression model., Results: We included 196 265 participants for the current manual work analysis, and 96 563 participants for the dose-response analysis. Participants whose current occupation usually/always involved manual work were more often affected with DD than participants whose occupation sometimes/never involved manual work (OR 1.29, 95% CI 1.12 to 1.49, p<0.001). There was a positive dose-response relationship between cumulative manual work exposure score and DD. Each increment in cumulative work exposure score increased the odds by 17% (OR 1.17, 95% CI 1.08 to 1.27, p<0.001)., Conclusions: Manual work exposure is a risk factor for DD, with a clear dose-response relationship. Physicians treating patients should recognise DD as a work-related disorder and inform patients accordingly., Competing Interests: Competing interests: PW was SERB-member and is DMC-member for Fidia Ltd, Milan Italy.

Background: Facial palsy rehabilitation therapy plays an essential role in treating facial palsy., Purpose: This study aimed to gain insight into therapists' perceptions and attitudes toward facial palsy rehabilitation therapy and to examine whether therapists could be categorized into distinct groups based on these attitudes and perceptions., Methods: Thirteen semi-structured, in-depth interviews were conducted in a purposive sample of therapists. Interviews were analyzed using thematic analysis. Next, a questionnaire containing questions about therapists' characteristics and perceptions and attitudes toward facial palsy rehabilitation therapy was sent to all facial palsy rehabilitation therapists in the Netherlands and Flanders (n = 292). Latent class analysis (LCA) was performed to identify and analyze distinct groups of therapists., Results: Seven themes were derived from the interviews: treatment goals, therapy content, indications, measurement instruments, factors influencing success, emotional support, and cooperation with colleagues. The questionnaire was filled out by 127 therapists. A 2-group structure consisting of a positive class and a negative class was found to fit the questionnaire data best. No distinction could be made regarding therapists' characteristics., Conclusion: Considerable variation in stated treatment practices was present among therapists. Therapists could be classified into 2 groups. This study raises several hypotheses that require further study.

Dupuytren's disease is a chronic, progressive fibroproliferative condition of the hand fascia which results in digital contraction. So far, treatments do not directly interfere with the (myo)fibroblasts that are responsible for the formation of the collagen-rich cords and its contraction. Here we investigated whether verteporfin (VP) is able to inhibit the activation and subsequent differentiation of DD nodular fibroblasts into myofibroblasts. Fibroblasts were isolated from nodules of 7 Dupuytren patients. Cells are treated (1) for 48 h with 5 ng/ml transforming growth factor β1 (TGF-β1) followed by 48 h with/without 250 nM VP in the absence of TGF-β1, or treated (2) for 48 h with TGF-β1 followed by 48 h with/without VP in the presence of TGF-β1. mRNA levels were measured by means of Real-Time PCR, and proteins were visualized by means of Western blotting and/or immunofluorescence. Quantitative data were statistically analyzed with GraphPad Prism using the paired t-test. We found that fibroblasts activated for 48 h with TGF-β1 show a decrease in mRNA levels of COL1A1, COL3A1, COL4A1, PLOD2, FN1EDA, CCN2 and SERPINE1 when exposed for another 48 h with VP, whereas no decrease is seen for ACTA2, YAP1, SMAD2 and SMAD3 mRNA levels. Cells exposed for an additional 48 h with TGF-β1, but now in the presence of VP, are not further activated anymore, whereas in the absence of VP the cells continue to differentiate into myofibroblasts. Collagen type I, fibronectin-extra domain A, α-smooth muscle actin, YAP1, Smad2 and Smad3 protein levels were attenuated by both VP treatments. We conclude that VP has strong anti-fibrotic properties: it is able to halt the differentiation of fibroblasts into myofibroblasts, and is also able to reverse the activation status of fibroblasts. The decreased protein levels of YAP1, Smad2 and Smad3 in the presence of VP explain in part the strong anti-fibrotic properties of VP. Verteporfin is clinically used as a photosensitizer for photodynamic therapy to eliminate abnormal blood vessels in the eye to attenuate macular degeneration. The antifibrotic properties of VP do not rely on photo-activation, as we used the molecule in its non-photoinduced state., (© 2022. The Author(s).)

Background: This study aimed to evaluate whether the implementation of extra perioperative safety measures and precautions through adopted standard operating procedures (SOPs) to ensure optimal anti-microbial conditions has led to less surgical site infections (SSI) after alloplastic breast reconstruction (BR)., Methods: This retrospective study compared two Cohorts of patients treated before and after the implementation of new SOPs (2009-2014: Cohort 1 versus 2014-2019: Cohort 2). Multivariate logistic regression analyses, adjusting for patient confounders, were implemented to compare SSI incidence between both Cohorts., Results: Overall, SSI incidence was equal in both groups (10%, p = 0.545). The incidence of deep SSI was 9% for Cohort 1 and 5% for Cohort 2 (p = 0.074). Incidence of SSI-related explantation was 8% and 5%, respectively (p = 0.136). After adjusting for patient confounders, no statistically significant difference was seen between both Cohorts in overall SSI, deep SSI incidence, and explantation due to SSI (OR adjusted : -0.31, p = 0.452, OR adjusted: 0.16, p = 0.747 and OR adjusted: 0.18, p = 0.712). Higher BMI, smoking, one-stage BR, and immediate BR were associated with the risk for SSI (p<0.001, p = 0.036, p<0.001, and p = 0.022, respectively)., Conclusion: Extra safety measures to assure optimal anti-microbial conditions did not contribute to lower SSI incidence or SSI-related explantation after alloplastic BR. Confounders such as BMI, smoking, immediate BR, and one-stage BR were correlated to an increased risk for overall SSI, deep SSI, and SSI-related explantation of TE/implants., Competing Interests: Declaration of Competing Interest None., (Copyright © 2022 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Introduction: Facial function correlates with quality of life in facial palsy. Previous studies have examined a linear relationship; based on clinical experience, we hypothesize a curved regression (i.e. quadratic or cubic) will be more fitting to show the correlation between quality of life and facial function., Methods: We compared the fit of a linear regression model between Sunnybrook scores (facial function) and FaCE and FDI scores (quality of life) to a quadratic and cubic regression model in 125 patients cross-sectionally., Results: A total of 125 patients were included, 53.6% female with a mean (standard deviation) age of 56.6 (16.7) and a median (interquartile range) duration of palsy of 6.6 (1.5; 18.3) years. The quadratic regression proved a significant improvement over a linear regression analysis in the model using the FaCE total score (linear R 2 =.346, quadratic R 2 = .378, p = .033) and the FDI physical score (linear R 2 = .245, quadratic R 2 =.276, p = .034). The cubic regression analysis was no significant improvement over a quadratic regression., Discussion: The relationship between facial function and quality of life in facial palsy is not linear meaning that there is a lot of variation in QoL in cases with severe and moderate facial impairment. This is most applicable to patients suffering from post-paralysis synkinesis, proving the highly individually experienced burden of synkinesis. As the relationship is not linear it should not be included as such in future research studies., (© 2022 John Wiley & Sons Ltd.)

Background: Predicting progression of Dupuytren disease becomes relevant in an upcoming era with progression-preventing treatment. This study aimed to determine the course of Dupuytren disease and identify factors associated with progression., Methods: Two hundred fifty-eight patients with Dupuytren disease participated in this prospective cohort study, obtaining 17,645 observations in 5 years. Outcomes were disease extent (surface area) and contracture severity (total passive extension deficit). Demographics, lifestyle, health status, exposure to manual work, and genetic risk scores were gathered as potential predictors. Subject-specific, mixed-effects models were used to estimate disease course, and logistic regression with least absolute shrinkage and selection operator was used to evaluate factors associated with the presence of progression., Results: On average, Dupuytren disease was progressive in all finger rays with regard to area [yearly increase, 0.07 cm2 (95% CI, 0.02 to 0.13 cm2) to 0.25 cm2 (95% CI, 0.11 to 0.39 cm2)]. Progression in total passive extension deficit was only present on the small finger side [yearly increase, 1.75 degrees (95% CI, 0.30 to 3.20 degrees) to 6.25 degrees (95% CI, 2.81 to 9.69 degrees)]. Stability or regression in area and total passive extension deficit was observed in 11 and 13 percent and 16 and 15 percent (dominant and nondominant hands), respectively. Smoking, cancer, genetic risk score, and hand injury were univariate associated with progression in area, but after multivariate variable selection, none of these associations remained. No predictors for progression in total passive extension deficit were found., Conclusions: Dupuytren disease is progressive, especially with respect to disease extent. Progression in contracture severity is mainly present on the small finger side of the hand. None of the traditional risk and diathesis factors were associated with progression, indicating that new hypotheses about Dupuytren disease progression might be needed., Clinical Question/level of Evidence: Risk, III., (Copyright © 2022 by the American Society of Plastic Surgeons.)

Introduction: The aim of this study was to evaluate whether sarcopenic obesity and muscle quality as expressed by skeletal muscle radiodensity (SMD) are associated to postoperative complications in women undergoing DIEP-flap breast reconstruction (BR)., Methods: All patients who underwent DIEP-flap BR at our tertiary center between 2010 and 2018 were asked to sign informed consent for the use of their electronic medical records and images. By outlining anatomical skeletal muscle contours on the preoperative abdominal CT-scan at lumbar level L3, SMD and skeletal muscle indices (SMI) were measured by two observers independently. Using logistic regression analyses, the association between sarcopenic obesity (BMI >25 & SMI <39), low SMD (<40HU), and Clavien-Dindo (CD) grade ≥ II complications was evaluated. In this way odds ratios (OR) and adjusted odds ratios (OR adjusted ) were provided., Results: Out of the 103 patients included in this study, 36% had CD grade ≥ II complications within 30 days of surgery. Twenty patients (19%) suffered from sarcopenic obesity of whom eleven patients (55%) had CD grade ≥ II complications (OR = 2.7, p = 0.05). In a multivariate analysis, sarcopenic obesity was not significantly related to a higher complication rate (OR adjusted = 2.2, p = 0.14) but women with SMD below average and those with prior radiotherapy had a higher risk for grade ≥ II complications (OR adjusted = 2.9, p = 0.02 and OR adjusted = 2.7, p = 0.02 respectively)., Conclusion: Below average SMD (<40HU) was found to be associated with the development of postoperative CD grade ≥ II complications in women undergoing DIEP-flap BR. Future research should evaluate whether improving SMD reduces the complication incidence in this patient group., Competing Interests: The authors declare the following conflict of interests: Paul Werker is member of a SERB for Fidia Ltd, Milan Italy., (© 2022 The Author(s).)

Objective(s): To interpret change in quality-of-life scores in facial palsy patients by calculating the smallest detectable change (SDC) and minimal important change (MIC) for the Facial Disability Index (FDI), Facial Clinimetric Evaluation (FaCE) scale, and Synkinesis Assessment Questionnaire (SAQ). Materials and Methods: The SDC, for individuals and groups, was calculated using previously collected test-retest data (2-week interval). The MIC (predictive modeling method) was calculated in a second similar facial palsy population using two measurements (1-1.5-year interval) and an anchor question assessing perceived change. Results: SDC individual of FaCE was 17.6 and SAQ was 28.2. SDC group of FaCE was 2.9 and SAQ was 4.6 ( n  = 62). Baseline FaCE and SAQ scores were 43.3 (interquartile range [IQR]: 35.8;55.0) and 51.1 (IQR: 32.2;60.0), respectively. MIC for important improvement of FDI physical/social function, FaCE total, and SAQ total were 4.4, 0.4, 0.7, and 2.8, respectively ( n  = 88). MIC for deterioration was 8.2, -1.8, -8.5, and 0.6, respectively. Baseline scores were 70.0 (IQR: 60.0;80.0), 76.0 (68.0;88.0), 55.0 (IQR: 40.0;61.7), and 26.7 (IQR: 22.2;35.6), respectively. Number of participants reporting important change for the different questionnaires ranged from 3 to 23 per subscale. Conclusion: Interpreting change scores of the FDI, FaCE, and SAQ is appropriate for groups, but for individual patients it is limited by a substantial SDC.

This study aimed to determine the association between the echogenicity of Dupuytren's disease nodules and myofibroblast load, and between echogenicity and nodule hardness. Thirty-eight nodules were assessed sonographically. The echogenicity of nodules was measured objectively with Image J (grey-value) and subjectively by visual inspection (hypo-, mixed and hyper-echogenicity). These findings were compared with myofibroblast load measured by histopathological analysis. In a different cohort, 97 nodules were assessed for grey-value and nodule hardness using a tonometer. There was a moderate, significant, negative association between grey-value and myofibroblast load and the subjective visual measurements corresponded to this finding. There was also a moderate, significant, negative association between grey-value and nodule hardness. Ultrasound and tonometry may be useful in the selection of patients for possible future preventive treatments.

Background: The purpose of this study was to investigate the long-term effects of radiotherapy for patients with Ledderhose disease., Methods: Questionnaires were sent to all patients with Ledderhose disease who had been treated with radiotherapy at our centre between 2008 and 2017 and who consented to participate. Radiotherapy was performed with orthovolt or electrons in two separate courses of five daily fractions of 3 Gy. The questionnaires addressed items such as pain from Ledderhose disease (Brief Pain Inventory), quality of life (EURO-QOL-5D-5L), long-term side effects, and patients' levels of satisfaction with the effect of treatment. Descriptive statistics and non-parametric tests were used to analyse the results., Results: A total of 102 feet were irradiated in 67 patients (28 men, 39 women). Radiotherapy resulted in significant pain reduction: the mean pain score prior to radiotherapy, collected retrospectively, was 5.7 and 1.7 at time of assessment (p-value < 0.001). The following pain response scores were reported: progressive pain (0%), no change (22%; 22 feet), partial pain response (37%; 38 feet) and complete pain response (absence of pain) (41%; 42 feet). Seventy-eight percent of patients were satisfied with the treatment effect and 57% did not consider radiotherapy burdensome. The scores for societal perspective (0.856) and patients' perspective on quality of life (82.3) were each comparable to the reference values from the Dutch population in the same age category (0.857 and 80.6, respectively). The most commonly reported residual long-term side effect was dryness of the skin (n = 10; 15%)., Conclusion: Radiotherapy for Ledderhose disease results in long-term pain reduction in the majority of patients and has limited side effects. The treatment is well tolerated, patients feel satisfied, and quality of life is comparable to the reference population., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: P.M.N.

Background: Little is known about how satisfied women are with their breasts and which factors influence breast satisfaction. Therefore, the aim of this study was to elucidate this by collecting data on breast satisfaction from the general population in relation to age, body mass index, lifestyle, psychological, and physical well-being., Method: This study was a cross-sectional population survey performed in 2019 in the north of the Netherlands, among randomly selected women between 20 and 80 years. Breast satisfaction was measured in the 1334 participants with the preoperative reconstruction BREAST-Q module. Other applied questionnaires were the Hospital Anxiety and Depression Scale, Short Form Survey (SF-36), and a custom-made questionnaire on lifestyle and baseline characteristics. Representativeness was assessed by comparing the participants with Dutch normative data. Possible factors influencing "satisfaction with breasts" were analyzed using multivariate linear regression analyses., Results: The median (IQR) BREAST-Q score for "satisfaction with breasts" was mediocre: 63 (58-79) on a 0-100 scale. Higher age and higher SF-36 scores had a positive effect on breast satisfaction ( P < 0.001 and P < 0.001, respectively) and a higher body mass index, smoking and anxiety score greater than 8 were negatively associated ( P < 0.001, P = 0.013 and P < 0.001 respectively, multivariate linear regression analyses)., Conclusion: These data are the first European normative data and can serve as a reference in future population and patient-based studies regarding breast satisfaction., Competing Interests: Disclosure: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: The worldwide prevalence of Dupuytren's disease (DD) is 8%. DD is a chronic disease for which there is no cure. Various treatments are available., Methods: This review is based on pertinent publications retrieved by a selective search in PubMed and Embase., Results: Genetic factors account for 80% of the factors involved in causing this disease. Diabetes mellitus, hepatic diseases, epilepsy, and chronic occupational use of vibrating tools are also associated with it. Limited fasciectomy is the most common treatment and is considered the reference standard. Possible complications include persistent numbness in areas where the skin has been elevated, cold sensitivity, and stiffness, with a cumulative risk of 3.6 -39.1% for all complications taken together. The recurrence rate at 5 years is 12-73%. Percutaneous needle fasciotomy is the least invasive method, with more rapid recovery and a lower complication rate than with limited fasciectomy. 85% of patients have a recurrence after an average of 2.3 years. Radiotherapy can be given before contractures arise in patients with high familial risk, or postoperatively in selected patients with a very high individual risk of recurrence., Conclusion: Although DD is not curable, good treatments are available. Recurrences reflect the pathophysiology of the disease and should not be considered complications of treatment. When counseling patients about the available treatment options, particularly the modalities and timing of surgery, the physician must take the patient's degree of suffering into account. Nowadays, fast recovery from surgery and less postoperative pain are a priority for many patients. Different surgical methods can be used in combination. It remains difficult to predict the natural course and the time to postoperative recurrence in individual patients; these matters should be addressed in future studies.

Importance: Understanding how the quality of life of adults (≥18 years) with peripheral facial palsy can be estimated using clinician measures of facial function and patient-reported variables might aid in counseling patients and in conducting research., Objectives: To analyze associations between clinician-graded facial function and patient-reported quality of life in adults with peripheral facial palsy, compare associations between facial function and the physical and social functions of quality of life, and examine factors that might influence the associations., Data Sources: A literature search was conducted in PubMed, Embase, CINAHL, Web of Science and PsycInfo on June 4, 2020, with no restrictions on the start date., Study Selection: Twenty-three studies reporting an association between clinician-graded facial function and patient-reported quality of life in adults with peripheral facial palsy were included. Facial function instruments included the House-Brackmann, Sunnybrook Facial Grading System, and electronic clinician-graded facial function assessment. Quality-of-life instruments included the Facial Disability Index and Facial Clinimetric Evaluation Scale., Data Extraction and Synthesis: Data extraction and qualitative synthesis were performed according to the Meta-analysis of Observational Studies in Epidemiology guidelines. Record screening, data extraction, and quality assessments were done by 2 researchers independently. Data were pooled using random-effects models., Main Outcomes and Measures: The main outcome was the association between facial function and quality of life, quantified by Pearson r, Spearman ρ, or regression analysis., Results: In total, 23 studies (3746 participants) were included. In the 21 studies that reported on the sex of the cohorts, there were 2073 women (57.3%). Mean or median age ranged from 21 to 64 years and mean or median duration of palsy ranged from newly diagnosed to 12 years. Bell palsy (n = 1397), benign tumor (n = 980), and infection (n = 257) were the most common etiologic factors. Pooled correlation coefficients were 0.424 (95% CI, 0.375-0.471) to 0.533 (95% CI, 0.447-0.610) between facial function and Facial Clinimetric Evaluation Scale total, 0.324 (95% CI, 0.128-0.495) to 0.397 (95% CI, 0.242-0.532) between facial function and Facial Clinimetric Evaluation Scale social function, 0.423 (95% CI, 0.322-0.514) to 0.605 (95% CI, -0.124-0.910) between facial function and Facial Disability Index physical function, and 0.166 (95% CI, 0.044-0.283) to 0.208 (95% CI, 0.031-0.373) between facial function and Facial Disability Index social function., Conclusions and Relevance: Associations noted in this systematic review and meta-analysis were overall low to moderate, suggesting that only a small part of quality of life is explained by facial function. Associations were higher between facial function and physical function than social function of quality of life.

The lotus petal flap can be applied for reconstruction of extensive defects in the vulvoperineal area. Studies on aesthetic outcomes are lacking. This study aimed to fill this gap., Methods: All patients who underwent lotus petal flap reconstruction between October 2011 and December 2015 were asked permission to have their photographs used. Two questionnaires were used: (1) the Strasser score to assess the overall aesthetic results (range 0-15) and (2) the Patient and Observer Scar Assessment Scale (POSAS; range 6-60). Six plastic surgeons and 6 laymen filled in the Strasser score and the Observer scale of the POSAS. Patients filled in the Strasser score, the Patient scale of the POSAS and scored their overall satisfaction with the aesthetic results on a Likert scale (0-10)., Results: The photographs of 11 patients were included. The median Strasser score of all observers of 11.9 (range 0.0-75.0) indicated a mediocre aesthetic result. The median total POSAS score of 15.6 (range 6.0-41.0) indicated an aesthetically acceptable scar. Strasser and POSAS scores of the plastic surgeons and laymen did not differ significantly from the patients' scores. The patient satisfaction score with the aesthetic result was a median of 6.0 of 10., Conclusions: The findings indicate that, overall, patients were moderately satisfied with the aesthetic results of their lotus petal flap reconstructions, as were the plastic surgeons and laymen. For clinical practice, it is important that the plastic surgeon manages expectations carefully before surgery, as it is possible that patients might experience a rather low aesthetic outcome after perineal reconstruction., (Copyright © 2021 The Authors.

Background: Vulvoperineal defects resulting from surgical treatment of (pre)malignancies may result in reconstructive challenges. The vertical rectus abdominis muscle flap and, more recently, the fasciocutaneous lotus petal flap are often used for reconstruction in this area. The goal of this review is to compare the postoperative complications of application of these flaps. Methods: A comprehensive literature search of the PubMed, MEDLINE and Cochrane Library databases was performed until 6 June 2020. Search terms included the lotus petal flap, vertical rectus abdominis muscle flap and the vulvoperineal area. Articles were independently screened by two researchers according to the PRISMA-guidelines. Results: A total of 1074 citations were retrieved and reviewed, of which 55 were included for full text analysis. Following lotus petal flap reconstructions, the complication rate varied from 0.0% to 69.9%, with more complications concerning the recipient site compared with the donor site complications (26.0% versus 4.5%). Following vertical rectus abdominis muscle flap reconstructions the complication rate varied between 0.0% and 85.7% with almost twice the number of recipient site complications compared to donor site complications (37.1% versus 17.8%). Conclusions: Overall, the lotus petal flap has lower complication rates at both the donor and the recipient site compared with the vertical rectus abdominis muscle flap. When both options seem viable, the lotus petal flap procedure may be preferred on the basis of the reported lower complication rates.

Aims: With novel promising therapies potentially limiting progression of Dupuytren's disease (DD), better patient stratification is needed. We aimed to quantify DD development and progression after seven years in a population-based cohort, and to identify factors predictive of disease development or progression., Methods: All surviving participants from our previous prevalence study were invited to participate in the current prospective cohort study. Participants were examined for presence of DD and Iselin's classification was applied. They were asked to complete comprehensive questionnaires. Disease progression was defined as advancement to a further Iselin stage or surgery. Potential predictive factors were assessed using multivariable regression analyses. Of 763 participants in our original study, 398 were available for further investigation seven years later., Results: We identified 143/398 (35.9%) participants with DD, of whom 56 (39.2%) were newly diagnosed. Overall, 20/93 (21.5%) previously affected participants had disease progression, while 6/93 (6.5%) patients showed disease regression. Disease progression occurred more often in patients who initially had advanced disease. Multivariable regression analyses revealed that both ectopic lesions and a positive family history of DD are independent predictors of disease progression. Previous hand injury predicts development of DD., Conclusion: Disease progression occurred in 21.5% of DD patients in our study. The higher the initial disease stage, the greater the proportion of participants who had disease progression at follow-up. Both ectopic lesions and a positive family history of DD predict disease progression. These patient-specific factors may be used to identify patients who might benefit from treatment that prevents progression. Cite this article: Bone Joint J  2021;103-B(4):704-710.

Abstract: Layperson assessments are becoming increasingly important in the evaluation of surgical procedures of the face, including smile reanimation. In this study, the authors set out to answer 3 questions: (1) are esthetic scores more dependent on the assessor or the person that is being assessed, (2) how does smile reanimation change esthetic scores, (3) do sex and age of the patient and assessor explain some of the esthetic outcomes?Thirty-five assessors scored pre and postoperative photographs of 21 facial palsy patients undergoing smile reanimation. Linear mixed-effect models were used to investigate the effects of assessor and patient factors on esthetic outcome assessments, to examine changes after smile reanimation, and to determine whether sex and age explained part of the esthetic outcomes.Fifty-eight percent of variation in the esthetic scores can be explained by some assessors being more positive in their esthetic scoring compared to other assessors. Twenty-nine percent was attributed to patient baseline esthetic scores. Overall esthetic scores improved after smile reanimation. Sex and age of the patient and assessor could not explain variation in the esthetic scores.Esthetic appearance highly depends on "who is looking." These findings are important for preoperative counseling, and for those treating and educating patients with facial palsy., Competing Interests: The authors report no conflicts of interest., (Copyright © 2020 by Mutaz B.

Background: Lotus petal flaps (LPF) may be used for the reconstruction of extralevator abdominoperineal defects that cannot be closed primarily. Limited data are available on how perineal reconstruction with the LPF impacts on patients' quality of life (QoL), sexual functioning, and physical functioning., Methods: A cross-sectional study was performed following perineal reconstruction with the LPF. The QoL of patients having undergone LPF reconstruction was compared with a control group in which perineal defects were closed without flaps. Sexual and physical functioning (presence of perineal herniation and range of motion [ROM] of the hip joints) could only be evaluated in the LPF group. Psychometrically sound questionnaires were used. Physical functioning was evaluated subjectively with binary questions and objectively by physical examination., Results: Of the 23 patients asked to participate, 15 (65%) completed the questionnaires and 11 (47%) underwent physical examination. In the control group, 16 patients were included. There were no significant differences in QoL between the LPF and control groups. Within the LPF group, 33% of patients were sexually active postoperatively compared with 87% preoperatively. No perineal herniation was found. The ROM of the hip joints was bilaterally smaller compared with the generally accepted values., Conclusions: Conclusions should be made with care given the small sample size. Despite a supposedly larger resection area in the LPF group, QoL was comparable in both groups. Nonetheless, reconstruction seemed to affect sexual function and physical function, not hampering overall satisfaction.

Peyronie's disease (PD) is a fibroproliferative disease of the penis. Since little is known about the molecular pathogenesis of PD, we compared the biochemical make-up of PD plaques with normal tunica albuginea to clarify pathological processes in the scarred tissue. Protein and mRNA levels were measured in plaques and in unaffected pieces of the tunica albuginea. We investigated the presence of myofibroblasts, the deposition of collagens, and some key elements of Wnt and YAP1 signaling at protein level. The expression of 45 genes, all related to collagen homeostasis and extracellular matrix proteins, was quantified. In plaques, more myofibroblasts were present, and we observed an activation of Wnt signaling and YAP1 signaling. Increased levels of the collagens types I and III confirm the fibrotic nature of plaques. The mRNA ratio of collagen types III, IV, and VI to type I was increased. The expression of lysyl hydroxylase 3 was higher, whereas a decreased expression level was seen for fibronectin and cathepsin K. The biochemical composition of plaques was different from unaffected tunica albuginea: the relative and absolute abundance of various extracellular matrix proteins were changed, as well as the quality of collagen and the level of the collagen-degrading enzyme cathepsin K.

Purpose: Patient-reported outcome measures are essential in the evaluation of facial palsy. Aim of this study was to translate and validate the Facial Disability Index (FDI) for use in the Netherlands., Methods: The FDI was translated into Dutch according to a forward-backward method. Construct validity was assessed by formulating 22 hypotheses regarding associations of FDI scores with the Facial Clinimetric Evaluation scale, the Synkinesis Assessment Questionnaire, the Short Form-12 and the Sunnybrook Facial Grading System. Validity was considered adequate if at least 75% (i.e. 17 out of 22) of the hypotheses were confirmed. Additionally, confirmatory factor analysis was performed. Cronbach's α was calculated as a measure of internal consistency. Participants were asked to fill out the FDI a second time after 2 weeks to analyse test-retest reliability. Lastly, smallest detectable change was calculated., Results: In total, 19 hypotheses (86.4%) were confirmed. Confirmatory factor analysis showed acceptable fit for the two factor structure of the original FDI (root mean square error of approximation = 0.064, standardized root mean square residual = 0.081, comparative fit index = 0.925, Chi-square = 50.22 with 34 degrees of freedom). Internal consistency for the FDI physical function scale was good (α > 0.720). Internal consistency for the FDI social/well-being scale was slightly less (α > 0.574). Test-retest reliability for both scales was good (intraclass correlation coefficients > 0.786). Smallest detectable change at the level of the individual was 17.6 points for the physical function and 17.7 points for the social/well-being function, and at group level 1.9 points for both scales., Conclusion: The Dutch version FDI shows good psychometric properties. The relatively large values for individual smallest detectable change may limit clinical use. The translation and widespread use of the FDI in multiple languages can help to compare treatment results internationally.

Background and Aims: The aim of this study was to evaluate the effect of smoking and body mass index on the occurrence of complications after alloplastic breast reconstruction., Materials and Methods: A consecutive series of 56 patients treated with immediate or delayed alloplastic breast reconstruction, including six cases combined with latissimus dorsi flap, at three hospitals between 2012 and 2018 were included. Complications were scored and defined according to Clavien-Dindo. To evaluate the impact of smoking, body mass index, and other potential risk factors on the occurrence of any and severe complications, univariate and multivariate logistic regression analyses were applied to estimate odds ratios and 95% confidence intervals., Results: In 56 patients, 22 patients had a complication. As much as 46% of smokers had severe complications compared to 18% of non-smokers. Of patients with body mass index ⩾ 25, 40% had severe complications compared to 10% with body mass index < 25. Smokers had eight times more chance of developing severe complications than non-smokers (OR adjusted  = 8.0, p  = 0.02). Patients with body mass index ⩾ 25 had almost 10 times more severe complications compared to patients with body mass index ⩽ 25 (OR adjusted  = 9.9, p  = 0.009). No other risk factors were significant., Conclusion: Smoking and body mass index ⩾ 25 both increased the complication rate to such an extent that patients should be informed about their increased risk for complications following alloplastic breast reconstruction and on these grounds surgeons may delay alloplastic breast reconstruction. It is an ethical dilemma whether one should deny overweight and obese patients and those who smoke an immediate alloplastic breast reconstruction. For both life style interventions, adequate guidance should be made available.

Purpose: In the future, it is expected that treatment of Dupuytren disease (DD) may shift toward control of early disease. Ultrasound might be an accurate method to measure the outcome of such treatment. The aim of this study was to assess the reliability of sonographic measurement of palmar nodules., Methods: Fifty patients with nodules characteristic for early disease were assessed with ultrasound by 2 observers. Four different aspects of DD nodules were measured in the transversal and sagittal planes, width, depth, circumference, and area. The intra- and interobserver reliabilities were calculated using the intraclass correlation coefficient (ICC). The standard error of measurement (SEM) and the smallest detectable change (SDC) were also calculated for each aspect., Results: The intraobserver reliability was good (ICC, 0.724 [0.562-0.833] to 0.886 [0.808-0.934]), except for width in the sagittal direction (ICC, 0.671 [0.484-0.799]). The interobserver reliability was moderate (ICC, 0.385 [0.126-0.596] to 0.757 [0.538-0.869]). The intraobserver ICCs of area were highest (transverse, 0.847 [0.744-0.893]; sagittal, 0.886 [0.808-0.934]). The SEM and SDC of area were 6.1 and 16.9 mm 2 in the transverse and 8.0 and 22.2 mm 2 in the sagittal plane., Conclusions: The intraobserver reliability of sonographic assessment of DD nodules is good. The measurement of area is the most reliable and is, therefore, recommended for future studies. However, even single-observer measurements have a clear dispersion, and a change beyond 16.9 (61%) and 22.2 mm 2 (79%) has to be observed in the transverse and sagittal planes, respectively, before it can be considered as regression or progression., Clinical Relevance: Repeated ultrasonographic measurements in DD should ideally be done by a single observer, using area of the nodule in the sagittal plane. Change beyond 16.9 (transverse) and 22.2 (sagittal) mm2 can be considered as a real change in nodule size., (Copyright © 2020 American Society for Surgery of the Hand. Published by Elsevier Inc.
