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.

ObjectivesDupuytren’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.MethodsIn 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.ResultsWe 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, pConclusionsManual 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.

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.

Item does not contain fulltext 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.

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.

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.

BackgroundLotus 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.MethodsA 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.ResultsOf 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.ConclusionsConclusions 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.

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 cm(2) (95% CI, 0.02 to 0.13 cm(2)) to 0.25 cm(2) (95% CI, 0.11 to 0.39 cm(2))]. 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.

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.

Objectives: We aimed to determine the relation between breast reconstruction method, patient satisfaction, and surgeon reported cosmetic outcome among women who underwent breast reconstruction after mastectomy.Study Design: A cross-sectional study of patients treated between 2006 and 2010.Main Outcome: Women's satisfaction with cosmetic outcomes after breast reconstruction.Measures: Cosmetic outcomes were evaluated by (1) women using the Breast-Q to rate satisfaction with breasts outcomes, and (2) an independent panel using the Strasser score. The relationships between the Breast-Q rating, Strasser scores, and breast reconstruction methods, including laterality and timing, were evaluated by Mann-Whitney U tests, Spearman's rank correlations, and Wilcoxon signed-rank tests.Results: Ninety-four women were included. Patients were more satisfied with their breasts if they had undergone autologous, unilateral, or secondary breast reconstruction compared with those who underwent alloplastic, bilateral, or primary breast reconstruction (p-values 0.008, 0.011, and 0.001, respectively). The Strasser system did not reveal significant cosmetic differences, with all breast reconstructions graded as mediocre or poor.Conclusions: Patient satisfaction with breast outcomes, as measured by the Breast-Q, was described as mediocre or poorly reflected by the Strasser score. If doctors are to support patients to make informed decisions on the optimal method of breast reconstruction, we need a more sensitive, comprehensive tool reflecting patients' cosmetic outcomes.

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 Pearsonr, 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.

Dupuytren disease (DD), a fibroproliferative disorder of the palmar fascia that causes flexion contractures in the fingers, is prevalent in people of North-Western European descent and less so in other ethnicities. DD is a complex disorder, influenced by genetic risk variants. We aimed to study if the marked differences in prevalences in DD between ethnic (sub)groups could be explained by differences in allele frequencies of the 26 known genetic risk variants of DD. Therefore, genetic risk scores (GRS) composed of the 26 DD risk variants were calculated for the 26 populations from the 1000 Genomes database and correlated to observed DD prevalences from literature. For comparison, GRSs were generated for 10,000 sets of 26 random SNPs and also correlated to the observed DD prevalences to determine the significance of the observed correlation. To determine whether differences in allele frequencies between ethnicities were caused by natural selection, fixation indices (Fst) were calculated from the 26 SNPs and from the sets of 26 random SNPs for comparison. Observed prevalences could be determined from literature for 10 populations. Their correlation with the GRS composed of DD SNPs proved to be 0.60 (p = 0.0003). The Fsts between British and other populations were low for European, ad mixed American, and South-Asian populations, and moderate for East-Asians. African populations were significantly different from expected values determined from the random sets. In conclusion, the 26 known genetic risk variants associated with DD explain for a substantial part (R-2 = 0.36) the differing DD prevalences observed between ethnicities.

KEY POINTS: Synkinesis can decrease quality of life in facial palsy patients. Patient-perceived severity of synkinesis may be of additional value in predicting facial palsy related-quality of life. We analyzed the additional value of the SAQ total score (perceived severity of synkinesis) in predicting FaCE total scores (quality of life) in 92 patients cross-sectionally. SAQ total score accounted for a relatively large improvement in the prediction of FaCE total scores (R2 change = 0.113, total R2 = 0.428). Patient-perceived severity synkinesis should be included in clinical management and studies of synkinesis. This article is protected by copyright. All rights reserved.

Objectives/Interrogation: Activity of Dupuytren nodules may be measured with ultrasound. It has been suggested that early nodules appear hypo-echogenic, whereas older nodules appear iso- to hyper-echogenic. The aim of this study was to analyse whether echogenicity of Dupuytren nodules can be used[for full text, please go to the a.m. URL], 14th Triennial Congress of the International Federation of Societies for Surgery of the Hand (IFSSH), 11th Triennial Congress of the International Federation of Societies for Hand Therapy (IFSHT), 11th Triennial Congress of the International Federation of Societies for Hand Therapy (IFSHT)

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 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 (ORadjusted = 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.

BACKGROUND: Literature suggests that patient-informing process prior to obtaining surgical informed consent (SIC) does not function well. This study aimed to provide insight into the current practice of SIC in the Netherlands.METHODS: This is a prospective, observational, and multicenter study, conducted in one academic and two non-academic teaching hospitals in the Netherlands. Audio recordings were made during outpatient consultations with patients presenting with Dupuytren Disease. The recorded informing process was scored according to a checklist. Written documentation of the SIC process in the patient's chart was compared to these scored checklists. Time spent on SIC during the consultations was also recorded.RESULTS: A total of 41 outpatient consultations were included in the study. Consultations were conducted by 25 plastic surgeons and their residents. Average time spent on SIC was 55.6% of the total consultation time. Considerable variation was observed concerning the amount and type of information given and discussed. In 59% of the consultations, discrepancies were observed between written documentation of consultations and audio recordings. Information on treatment risks, the postoperative period, and the operating surgeon was addressed the least.CONCLUSION: Despite a relatively large part of the consultation time being spent on SIC, patients received scarce information concerning treatment risks, postoperative period, and who their operating surgeon would be. Discrepancies were observed between the written documentation of SIC and information recorded on the audio recordings. This occurred predominantly in one hospital that used a pre-made list of 'discussed information' in its digital patient chart.

IMPORTANCE Study of the association of regional facial dysfunction with quality of life will lead to a better understanding of quality of life in facial palsy.OBJECTIVE To determine the association of regional facial dysfunction with facial palsy-related quality of life.DESIGN, SETTING, AND PARTICIPANTS This retrospective cohort analysis included patients with flaccid and nonflaccid (synkinetic) facial palsy treated at a tertiary care facial nerve center; the flaccid facial palsy group included 529 patients, and the nonflaccid facial palsy group included 391 patients. Data were included from all patients with facial palsy who had an eFACE score and Facial Clinimetric Evaluation (FaCE) scale total score acquired at the same time from February 1, 2014, through October 31, 2017. Linear regression analysis was performed to calculate the amount of variance in quality of life explained by the severity of facial palsy (eFACE). A relative weight analysis was performed for the contribution of each individual eFACE item in estimating quality of life.MAIN OUTCOMES AND MEASURES Facial palsy severity was measured using all 15 individual eFACE items (rated on a scale of 0 to 200, where 0 represents complete flaccidity, 100 represents a balanced aesthetic appearance, and 200 represents the worst imaginable hypertonia of a patient with synkinesis, with a transformation used for values from 101 to 200), and facial palsy-related quality of life was measured using the FaCE scale total score (range, 0 [worst] to 100 [best]).RESULTS Data of 920 individual patients (59.5% female; mean [SD] age, 48.6 [16.6] years) were available. The eFACE composite score accounted for 21.2% of the quality-of-life variance in the flaccid group and 13.9% in the nonflaccid group. With the use of all 15 individual eFACE items, these proportions increased to 29.7% and 16.8%, respectively. In both groups, oral commissure movement with smile was found to be the most important contributing item (relative weight, 0.108 [95% CI, 0.075-0.148] for the flaccid group and 0.025 [95% CI, 0.005-0.052] for the nonflaccid group). Items related to the function of periocular muscles were found to be of low importance.CONCLUSIONS AND RELEVANCE The present study suggests that the function of individual facial regions is not equally important for estimating facial palsy-related quality of life. The ability to smile is of greatest importance among patients with flaccid and nonflaccid facial palsy. The true importance of periocular function in the estimation of quality of life should be studied further in future research.

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.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.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.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

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.

Little is known about facial function assessments of inexperienced observers in facial palsy. In this observational study learning curve was examined of two inexperienced observers assessing facial function of 100 patients using the Sunnybrook Facial Grading System. Interobserver agreement gradually improved over time, stabilizing after approximately 70 assessments. Best agreement on the voluntary movement subscore was observed, followed by synkinesis and resting symmetry subscores. Inexperienced observers can perform facial function assessments in facial palsy, but should be adequately trained first.

Three-dimensional stereophotogrammetry is not much used in assessing facial palsy and a comprehensive understanding of sources of variation in these measurements is lacking. The present study assessed intra- and interobserver reliability of a novel three-dimensional stereophotogrammetry measurement of facial asymmetry and examined sources of variation in these outcomes. Three photographs (rest, closed mouth smile, and maximum smile) were made of 60 participants, 30 facial palsy patients and 30 control subjects. All images were analyzed twice by 2 observers independently, to determine intra- and interobserver reliability. Variance component analysis was performed to investigate sources of variation in the outcomes. Intraobserver reliability was good with intraclass correlation coefficients ranging from 0.715 to 0.999. Interobserver reliability ranged from 0.442 to 0.929. Reliability of the smile image measurements was not clearly different from the rest images. Variation in measurement results was largely due to the status of a participant, facial palsy versus control. When splitting the sample, the facial expression was a major source of variation. Acceptable reliability of the proposed 3D facial asymmetry measurement was found, in facial palsy patients and control subjects. Interobserver reliability was marked less compared to intraobserver reliability. For follow-up data only one observer should assess 3D stereophotogrammetry measurements.

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 mm2 in the transverse and 8.0 and 22.2 mm2 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 mm2 (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.

Background: This review aimed to meta-analyze the quality of life of alloplastic versus autologous breast reconstruction, when measured with the BREAST-Q. Methods: An electronic PubMed and EMBASE search was designed to find articles that compared alloplastic versus autologous breast reconstruction using the BREAST-Q. Studies that failed to present BREAST-Q scores and studies that did not compare alloplastic versus autologous breast reconstruction were excluded. Two authors independently extracted data from the included studies. A standardized data collection form was used. Quality was assessed using the Newcastle-Ottawa Scale. The mean difference and 95 percent confidence intervals between breast reconstruction means were estimated for each BREAST-Q subscale. Forest plots and the I2statistic were used to assess heterogeneity and funnel plot publication bias. The Z test was used to assess overall effects. Results: Two hundred eighty abstracts were found; 10 articles were included. Autologous breast reconstruction scored significantly higher in the five subscales than alloplastic breast reconstruction. The Satisfaction with Breasts subscale indicated the greatest difference, with a mean difference of 6.41 (95 percent CI, 3.58 to 9.24; I2= 70 percent). The Satisfaction with Results subscale displayed a mean difference of 5.52. The Sexual Well-Being subscale displayed a mean difference of 3.85. The Psychosocial Well-Being subscale displayed a mean difference of 2.64. The overall difference in physical well-being was significant, with high heterogeneity (mean difference, 3.33; 95 percent CI, 0.18 to 6.48; I2= 85). Conclusion: Autologous breast reconstruction had superior outcomes compared with alloplastic breast reconstruction as measured by the BREAST-Q.

BACKGROUND: Dupuytren, Peyronie, and Ledderhose diseases are related fibroproliferative disorders characterized by abnormalities in the connective tissue of the palm of the hand, the tunica albuginea of the penis, and the sole of the foot, respectively. Concomitant prevalence rates of these diseases have only been described in a few small populations. This article aims to report on a large population and to raise awareness in surgeons treating Dupuytren disease for concurring related fibroproliferative disorders.METHODS: Patients diagnosed as having Dupuytren disease were recruited from outpatient clinics in the northern part of the Netherlands from 2007 to 2016. Questionnaires concerning demographics, clinical characteristics, the coexistence of Ledderhose and/or Peyronie diseases, and other factors were filled in by the participants and by plastic surgeons.RESULTS: For 730 men with Dupuytren disease, the surgeons' reported prevalence rate of Peyronie disease was 7.8 percent and of Ledderhose disease was 16.1 percent. The participants themselves reported prevalence rates of 8.8 percent for Peyronie disease and of 22.0 percent for Ledderhose disease.CONCLUSIONS: In the Dupuytren patient cohort, the prevalence of Peyronie disease was lower than that described in the literature. The prevalence of Ledderhose disease corresponded with the rates from the literature. However, both were underreported by plastic surgeons, which calls for a rise in awareness, recognition, and referral to a urologist when the conditions are bothersome or symptomatic.

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.

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.

ObjectiveResection of (pre) malignant lesions in the vulvoperineal area may result in large defects that cannot be closed primarily. The lotus petal flap technique is widely used for reconstruction. The aim of this study was to evaluate both quality of life (QoL) and sexual functioning of patients who underwent the lotus petal flap procedure, because no data are available on this topic.MethodsA cross-sectional study was performed on all eligible patients (N = 38) who underwent the lotus petal flap procedure between 2005 and 2016. The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30, Female Sexual Function Index, and Body Image Scale were used to evaluate QoL and sexual functioning. The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 and Female Sexual Function Index scores were compared with scores of age-matched healthy women.ResultsTwenty-six patients (68%) responded. The mean (SD) age was 65.5 (16.3) years, and the median follow-up time was 38.5 months (range 16–141 months). Quality of life scores were lower compared with healthy women in the domains physical, role, and social functioning. Sexual activity rates were comparable with healthy women; however, sexual functioning was worse. Although patients were satisfied about their sexual life, pain was reported.ConclusionsPatients who underwent vulvar reconstructive surgery with lotus petal flaps seem to have a lower QoL compared with healthy women. Patients report more pain during sexual activity but are satisfied about their sexual functioning. These results should be included in preoperative counseling and follow-up of future patients eligible for vulvar reconstruction with a lotus petal flap.

Clinicians struggle with limited efficacy and durability of standard treatments when treating patients with Dupuytren disease diathesis. Alternative treatments such as low-dose radiation therapy in early phase of disease, supplemental pharmacotherapy with anti-inflammatory and/or anti-mitotic drugs, as well as other pharmacologic targets, and more aggressive surgery such as dermofasciectomy all have been reported with variable success or with serious side effects that hamper their standard use. This article gives an overview of the available literature.

The temporalis muscle transposition is a reliable, one-stage reanimation technique for longstanding facial paralysis. In the variation described by Rubin, the muscle is released from the temporal bone and folded over the zygomatic arch towards the modiolus. This results in unsightly temporal hollowing and zygomatic bulging. We present a modification of this technique, which preserves the temporal fat pad in its anatomical location as well as conceals temporal hollowing and prevents zygomatic bulging.The data of 23 patients treated with this modification were analysed. May classification was used for evaluation of mouth reanimation. Experts and patients scored visibility of the contour deformity on a 100-mm visual analogue scale (VAS) (score 0 = poor/100 = best). 3D images of the face were used to measure temporal hollowing and zygomatic bulging. 3D images were compared to those of controls with a similar gender and age distribution.After a median follow-up of 5.7 years, all patients achieved symmetry at rest. Eleven patients achieved symmetry while smiling with closed lips (May classification "Good"). A median (interquartile range [IQR]) VAS score of 19 (6; 41) was given by experts and 25 (5; 59) by patients themselves. 3D volumes of zygomatic bulging differed from those of control subjects, although all volume differences were small (medianOn the basis of our results, we conclude that our modified Rubin temporalis transposition technique provides an elegant way to conceal bulging over the zygomatic arch and prevents temporal hollowing, without the need for fascial extensions to reach the modiolus.

Data of a prospective longitudinal cohort study including 233 Dupuytren’s patients was used to determine: (1) whether the Unité Rhumatologique des Affections de la Main scale and Michigan Hand outcomes Questionnaire can detect change in hand function due to Dupuytren’s disease progression and to compare their abilities; (2) the concurrent validity, reliability, responsiveness and interpretability of the Dutch Unité Rhumatologique des Affections de la Main. The Unité Rhumatologique des Affections de la Main and Michigan Hand outcomes Questionnaire had comparable measurement properties, and were both able to distinguish participants with disease progression from those without progression (resp.

Supplemental Digital Content is available in the text., Background: The role of diabetes mellitus, liver disease, and epilepsy as risk factors for Dupuytren disease remains unclear. In this systematic review and meta-analysis, the strength and consistency of these associations were examined. Methods: The MEDLINE, EMBASE, and Web of Science databases were searched for articles reporting an association between Dupuytren disease and diabetes mellitus, liver disease, and epilepsy published before September 26, 2016. The frequencies of Dupuytren disease and diabetes mellitus, liver disease, and epilepsy were extracted, as was information on potential confounders. Generalized linear mixed models were applied to estimate pooled odds ratios, adjusted for confounders. Heterogeneity between studies was quantified using an intraclass correlation coefficient and was accounted for by a random effect for study. Results: One thousand two hundred sixty unique studies were identified, of which 32 were used in the meta-analyses. An association between Dupuytren disease and diabetes mellitus was observed (OR, 3.06; 95 percent CI, 2.69 to 3.48, adjusted for age), which was stronger for type 1 diabetes mellitus than for type 2 diabetes mellitus but was not statistically significant (p = 0.24). An association between Dupuytren disease and liver disease was observed (OR, 2.92; 95 percent CI, 2.08 to 4.12, adjusted for sex). Dupuytren disease and epilepsy were associated, yielding an OR of 2.80 (95 percent CI, 2.49 to 3.15). Heterogeneity between studies was moderate to low. Conclusions: These findings demonstrate an association between Dupuytren disease and diabetes mellitus, liver disease, and epilepsy. Prospective, longitudinal studies are needed to elucidate the pathways causing these associations.

Background: 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 Liken. 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.

Summary Nerve reconstructions are the preferred technique for short-standing facial paralysis, most commonly using the contralateral facial nerve or ipsilateral hypoglossal nerve. The hypoglossal nerve provides a strong motor signal, whereas the signal of a cross-face nerve graft is weaker but spontaneous. Spontaneity in facial expression is believed to be important for psychological wellbeing. Therefore, a combination of the two procedures incorporates the best of both: a strong motor signal and a spontaneous smile. This study aimed to objectify this expected benefit. Of the 20 patients who received a hypoglossal–facial nerve anastomosis from 1995 to 2015 in our institutions, 12 patients were included in this study, 5 with and 7 without a cross-face nerve graft. The outcomes were compared using photographs, disease-specific quality of life (Facial Clinimetric Evaluation (FaCE) scale), a self-reported synkinesis scale (Synkinesis Assessment Questionnaire) and the presence of a spontaneous smile. Significant differences were found in preoperative excursion of the affected side of the mouth and the change in excursion. Median Total FaCE scores were considerably larger (18.3 points) for patients who underwent the combined procedure. A spontaneous smile was observed both with ( n = 2) and without ( n = 1) a cross-face nerve graft. The addition of a cross-face nerve graft to a hypoglossal–facial nerve anastomosis resulted in a positive trend in disease-specific quality of life. This benefit could also be present with the combination of a cross-face nerve graft with another nerve transfer such as a masseteric-facial nerve anastomosis.

Background: Percutaneous needle fasciotomy is a minimally invasive treatment modality for Dupuytren disease. In this study, the authors analyzed the efficacy and complication rate of percutaneous needle fasciotomy using a statistical method that takes the multilevel structure of data, regarding multiple measurements from the same patient, into account.Methods: The data of 470 treated rays from 451 patients with Dupuytren disease that underwent percutaneous needle fasciotomy were analyzed retrospectively. The authors described the early postoperative results of percutaneous needle fasciotomy and applied linear mixed models to compare mean correction of passive extension deficit between joints and efficacy of primary versus secondary percutaneous needle fasciotomy.Results: Mean preoperative passive extension deficits at the metacarpophalangeal, proximal interphalangeal, and distal interphalangeal joints were 37, 40, and 31 degrees, respectively. Mean preoperative total passive extension deficit was 54 degrees. Results were excellent, with a mean total passive extension deficit correction of 85 percent. Percutaneous needle fasciotomy was most effective for metacarpophalangeal joints and less effective for proximal interphalangeal and distal interphalangeal joints. Secondary percutaneous needle fasciotomy was as effective as primary percutaneous needle fasciotomy. Complications were rare and mostly minor.Conclusion: The results of this study confirm that percutaneous needle fasciotomy is an effective and safe treatment modality for patients with mild to moderate disease who prefer a minimally invasive procedure.

The anatomy in the region of the palmodigital junction has been relatively little studied, but it is very relevant for the surgical treatment of Dupuytren’s disease. To study the microanatomy of the palmodigital junction, we dissected 26 cadaveric digits from 13 human cadaveric hands using microsurgical techniques. The dynamics of the different ligaments were studied in three hands preserved by Thiel’s method. We found a structure, which we propose to name the ‘palmodigital spiralling sheet’ (PSS), which has not been described before. It has a spiralling course around the neurovascular bundle giving rise to a neurovascular tunnel distally in the palm of the hand. It is formed proximally by fibres from the pretendinous band and the intrinsic muscle fascias and distally is in continuity with Cleland’s and Grayson’s ligaments. As such it connects the palmar and digital fascias. Its spiralling course stabilizes the neurovascular bundle in the healthy hand, but can displace it in Dupuytren’s disease, which may contribute to the development of spiral cords.

Syndactyly correction without skin grafting is advocated because it prevents graft-related complications and donor site morbidity. In this cross-sectional study, we compared satisfaction among patients who underwent correction with and without skin grafting to determine preference based on subjective and objective parameters. Retrospective chart analysis was performed among 27 patients (49 webs) who were seen at follow-up after a median follow-up period of 7.4 years, at which the Patient and Observer Scar Assessment Scale, the Withey score and a satisfaction survey were used. Notably, there were no significant differences in complication rates or observer rated scar scores. Although the need for an additional surgical procedure was higher after skin grafting, patient-rated satisfaction scores were similar irrespective of the use of grafting. Our data suggest that corrections can best be performed without skin grafts if seeking to minimize the need for an additional procedure, but that the use of skin grafts does not appear to affect patient satisfaction.

Supplemental Digital Content is available in the text., Background: Dupuytren’s disease is a very common, highly heritable palmar fibromatosis. In a recent genome-wide association study, 26 single-nucleotide polymorphisms were found to be associated with development of Dupuytren’s disease. The authors generated a weighted genetic risk score based on the genotype at these single-nucleotide polymorphisms. In two independent cohorts, they tested the association among high weighted genetic risk score, clinical features that predict a high risk of recurrence, and recurrence after surgery. Methods: Clinical data were obtained from patient questionnaires and clinical records, with missing data accounted for by imputation. Genotyping was performed as part of the recent genome-wide association study. Logistic regression was performed to study the association among weighted genetic risk score, high-risk clinical features, and recurrence, with a weighted genetic risk score analyzed as a continuous variable, and also grouped into four categories. Results: Using univariable logistic regression, a high weighted genetic risk score was associated with the presence of all high-risk clinical features: early age of onset, bilateral disease, ectopic disease, and a positive family history (p ≤ 0.004). After multivariable logistic regression accounting for these factors, an increased weighted genetic risk score was still associated with the need for repeated Dupuytren’s disease surgery (p = 0.004). Conclusions: The authors’ results suggest that a weighted genetic risk score is useful in predicting the risk of disease recurrence, and may be used by surgeons to personalize prognostication. In the future, a weighted genetic risk score may be useful for determining the most appropriate initial surgical procedure in patients with Dupuytren’s disease.

Background: In longstanding facial palsy, gracilis free functional muscle transfer (FFMT) is currently considered to be the gold standard in smile reanimation. An alternative to muscle free flaps is local muscle transposition, with the temporalis muscle transposition being the preferred procedure, because of its direction of pull when transposed. The present study aimed to compare outcomes of gracilis FFMT neurotised by the masseteric nerve and temporalis muscle transposition in longstanding facial palsy using patient-reported and aesthetic outcomes.Methods: A cross-sectional comparison of gracilis FFMT and temporalis muscle transpositions was performed. Pre- and postoperative excursion measures were obtained. Patients were asked to answer a satisfaction questionnaire, quality of life questionnaire (FaCE scale) and a depression and anxiety questionnaire (HADS). Laypeople were asked to rate the pre- and postoperative aesthetic appearance.Results: Of 28 eligible patients, 10 gracilis and 12 temporalis patients participated. No significant differences were found between both groups in postoperative quality of life or depression/anxiety. Layperson observers judged the aesthetic appearance to be similar.Conclusion: In the present study, gracilis FFMT did not lead to superior quality of life and aesthetic outcomes compared to temporalis muscle transpositions. The facial nerve specialist should perform the procedure he or she expects to lead to optimal results for the patient. (C) 2018 European Association for Cranio-Maxillo-Facial Surgery.

Genetic background plays an important role in the development of Dupuytren’s disease. A genome-wide association study (GWAS) showed that nine loci are associated with the disease, six of which contain genes that are involved in Wnt signaling (WNT2, WNT4, WNT7B, RSPO2, SFRP4, SULF1). To obtain insight in the role of these genes, we performed expression studies on affected and unaffected patient’s tissues. Surgically obtained nodules and cords from eight Dupuytren’s patients were compared to patient-matched control tissue (unaffected transverse palmar fascia). The Wnt-related genes found in the GWAS, the classical Wnt-downstream protein β-catenin, as well as (myo)fibroblast markers were analyzed using real-time qPCR and immunohistochemical stainings for mRNA levels and protein levels, respectively. The collagen-coding genes COL1A1 and COL3A1 were highly upregulated on mRNA level, both in cords and nodules. Three Wnt-related genes were found to be differently regulated compared to control tissue: WNT2 was downregulated in nodules, WNT7B was upregulated in nodules, and SFRP4 was upregulated in nodules and cords. Immunohistochemistry revealed significantly less staining of Wnt2 in cords, but significantly more staining for Wnt7b in nodules. There was significantly more staining of α-SMA in nodules and cord and β-catenin in nodules than in control tissue. We found differences in expression, both at mRNA and protein level, in several Wnt-related genes found earlier to be associated with Dupuytren’s disease. Of these, Wnt7b was upregulated and found in close association with both α-SMA and β-catenin expressing cells, making it a candidate pro-fibrotic mediator in Dupuytren’s disease.

Dupuytren disease is a fibrotic disorder characterized by contraction of myofibroblast-rich cords and nodules in the hands. The Hippo member Yes-associated protein 1 (YAP1) is activated by tissue stiffness and the profibro tic transforming growth factor-beta 1, but its role in cell fibrogenesis is yet unclear. We hypothesized that YAP1 regulates the differentiation of dermal fibroblasts into highly contractile myofibroblasts and that YAP1 governs the maintenance of a myofibroblast phenotype in primary Dupuytren cells. Knockdown of YAP1 in transforming growth factor-beta 1-stimulated dermal fibroblasts decreased the formation of contractile smooth muscle alpha-actin stress fibers and the deposition of collagen type I, which are hallmark features of myofibroblasts. Translating our findings to a clinically relevant model, we found that YAP1 deficiency in Dupuytren disease myofibroblasts resulted in decreased expression of ACTA2, COL1A1, and CCN2 mRNA, but this did not result in decreased protein Levels. YAP1-deficient Dupuytren myofibroblasts showed decreased contraction of a collagen hydrogel. Finally, we showed that YAP1 Levels and nuclear localization were elevated in affected Dupuytren disease tissue compared with matched control tissue and partly co-localized with smooth muscle alpha-actin-positive cells. In conclusion, our data show that YAP1 is a regulator of myofibroblast differentiation and contributes to the maintenance of a synthetic and contractile phenotype, in both transforming growth factor-beta 1-induced myofibroblast differentiation and primary Dupuytren myofibroblasts.

Introduction: Adipose tissue is a major component of the breast cancer microenvironment, and preclinical studies have suggested that adipose tissue might play a pivotal role in breast cancer progression. In this study we investigated the effect of adipose tissue from patients with ER positive breast cancer on migration of ER positive MCF-7 breast cancer cells. Materials and Methods: Adipose tissue samples were collected from patients with ER positive breast cancer undergoing a mastectomy. In total, adipose tissue samples from 3 normal weight (BMI: 18.5-24.9) and 7 overweight breast cancer patients (BMI: 25-29.9) were collected. Samples from the mastectomy specimens were minced in small pieces, incubated in RPMI-1640 and after 48 hours (h) the supernatant was harvested. The effect of adipose tissue supernatant on the migration of MCF-7 cells was monitored in real-time for 48 h with the xCELLigence cell invasion and migration plates expressed in delta cell index (DCI). In addition, effect of adipose tissue supernatant on migration was assessed by quantification of F-actin positive lamellipodia of MCF-7 cells in a scratch assay after 24 h. In all experiments, RPMI-1640 with 1% or 20% FCS was used as a negative or positive control respectively. Results: Supernatant of overweight patients significantly induced MCF-7 migration compared to supernatant of normal weight patients after 24 h (xCELLigence DCI: 1.22 ± 0.15 vs. 0.95 ± 0.19 (P=0.038)), 36 h (DCI 1.40 ± 0.21 vs. 0.91 ± 0.31 (P=0.019)) and 48 h (DCI 1.72 ± 0.23 vs. 0.98 ± 0.43 (P=0.007)). In addition, there was a significant difference between the overweight group and negative control at 36 h, and 48 h (DCI 1.40 ± 0.21 vs. 1.06 ± 0.12, P=0.038 and DCI 1.72 ± 0.23 vs. 1.11 ± 0.21, P=0.004 respectively). No significant difference between normal weight group and negative control was found at any of the time points. After 24 h MCF-7 cells incubated with supernatant of overweight patients developed significantly more F-actin positive lamellipodia compared to MCF-7 cells incubated with supernatant of normal weight patients (44.26 ± 3.26% vs. 25.47 ± 1.88% P Conclusion: In this study, we showed that adipose tissue supernatant of patients with ER positive breast cancer can promote migration of MCF-7 breast cancer cells in a weight dependent manner. Whether this is the case in other breast cancer subtypes as well, and the potential clinical implication, is of interest for future studies. Citation Format: Jie Ma, Hetty Timmer-Bosscha, Paul M.

Importance: Knowledge of factors associated with health-related quality of life in patients with facial palsy may aid in better interpreting outcomes of research and treatment.Objective: To identify factors associated with health-related quality of life in patients with facial palsy.Design, Setting, and Participants: The inclusion period for participants in this cross-sectional study at the University Medical Center Groningen, a tertiary referral center for facial reanimation surgery, was March 1 to June 1, 2019. Patients aged at least 18 years with facial palsy who had undergone surgery for facial palsy between January 1, 2007, and January 1, 2018, and patients visiting the outpatient clinic of the University of Groningen Department of Plastic Surgery for their facial palsy between March 1 and June 1, 2019, were also asked to participate. Of 276 patients invited, 145 gave informed consent. Twenty patients did not respond after consent, 3 patients withdrew from the study, and 1 patient was wrongly included.Main Outcomes and Measures: Health-related quality of life was measured using the Facial Clinimetric Evaluation Scale and the Facial Disability Index (physical score and social score). Facial function was assessed with the Sunnybrook Facial Grading System. Other variables were investigated using validated questionnaires, including the Duke University Religion Index, Ten-Item Personality Inventory, and Hospital Anxiety and Depression Scale. Multivariable linear regression analyses with stepwise backward selection were performed to identify associations with health-related quality of life. Because 44 Sunnybrook composite scores were missing, a sensitivity analysis was performed that excluded the Sunnybrook composite scores from the multivariable analysis.Results: In total, 121 patients with facial palsy were included; their median age was 62 years (interquartile range, 48-71 years), and 63 (52%) were women. Sunnybrook composite score (β = 0.4; 95% CI, 0.2-0.5), extraversion (β = 2.6; 95% CI, 0.4-4.8), and anxiety (β = -2.4; 95% CI, -4.1 to -0.8) were associated with the Facial Clinimetric Evaluation Scale total score (R2 = 0.380; 95% CI, 0.212-0.548). The Sunnybrook composite score was associated with the Facial Disability Index physical score (β = 0.2; 95% CI, 0.0-0.4) (R2 = 0.084; 95% CI, -0.037 to 0.205). Bilateral facial palsy (β = -21.2; 95% CI, -32.3 to -10.1), extraversion (β = 2.7; 95% CI, 1.3-4.1), conscientiousness (β = 2.7; 95% CI, 0.2-5.2), emotional stability (β = 3.3; 95% CI, 1.7-4.8), and depression (β = -1.3; 95% CI, -2.5 to -0.1) were associated with the Facial Disability Index social score (R2 = 0.400; 95% CI, 0.262-0.538). In the sensitivity analysis, the Sunnybrook composite score was associated with age (Spearman ρ = -0.252).Conclusions and Relevance: Bilateral facial palsy, age, severity of facial palsy, mental distress, and personality traits should be taken into account in future research and treatment of patients with facial palsy.
