RESUMEN
BACKGROUND: In patients with Hirschsprung disease (HSCR), soiling may be related to anal sphincter damage following the initial pull-through. No optimal treatment has been developed for such patients, although enemas (rectal or antegrade) have been applied with some success. We present the one-year outcomes of a new technique for anal sphincter reconstruction. METHODS: All patients with HSCR referred from other institutions for post pull-through soiling were studied. Seven patients with patulous sphincters underwent sphincter reconstruction. Six had a full preoperative evaluation and were included in the study. Their 12-month outcomes were assessed. RESULTS: All six patients had soiling without voluntary bowel movements (VBMs). One patient was clean on Malone flushes when referred. Three underwent pre- and post-reconstruction non-sedated three-dimensional anorectal manometry, and objectively were able to close their sphincters following the reconstruction. All patients without Down syndrome (4 of 6) showed improvement in the abbreviated Baylor Continence Scale (4.5 vs. 0.75). One patient has achieved total bowel control without antegrade flushes, three now have VBMs which they did not have before but have occasional accidents and use antegrade flushes intermittently. They reported higher productivity, the ability to participate in sports and be away from home with confidence in their regimen. Two of 6 patients have Down syndrome and required a redo pull-through for other indications and underwent empiric sphincter reconstruction. For these two patients we do not have an outcomes assessment. CONCLUSIONS: A new technique for sphincter reconstruction shows promising results in improvement of bowel control at one year. LEVEL OF EVIDENCE: IV.

Introduction: Shifting the training from the operating room (OR) to simulation models has been proven effective in enhancing patient safety and reducing the learning time to achieve competency and increase the operative efficiency. Currently the field of pediatric surgery only offers few low-cost trainers for specialized training and these feature predominantly artificial and often unrealistic tissue. The aim of this study was to develop an easy access low-cost tissue-realistic simulation model for open training of esophageal atresia and to evaluate the acceptance in trainees and junior pediatric surgeons. Materials and methods: The model is fashioned using reconfigured chicken skin from a chicken leg. To create a model of esophageal atresia, the chicken skin is dissected off the muscle and reconfigured around a foley catheter balloon to recreate the proximal pouch and a feeding tube to recreate the distal pouch. Surrounding structures such as the tracheo-esophageal fistula and the azygos vein can be easily added, obtaining a realistic esophageal atresia (Type C) prototype. Evaluation of model construction, usage and impact on user were performed by both a self-assessment questionnaire with pre- and post-training questions as well as observer-based variables and a revised Objective Structured Assessment of Technical Skills (OSATS) score. Results: A total of 10 participants were constructing and using the model at two different timepoints. OSATS score for overall performance was significantly higher (p = 0.005, z = -2.78) during the second observational period [median (MD): 4,95% confidence interval CI: 3.4, 5.1] compared to the first (MD: 3, 95% CI 2.4, 4.1). Self-reported boost in confidence after model usage for performing future esophageal atresia (EA) repair and bowel anastomosis (BA) in general was significantly higher (EA: U = 1, z = -2.3, p = 0.021, BA: U = 1, z = -2.41, p = 0.016) in participants with more years in training/attending status (EA MD:5, BA MD: 5.5) compared to less experienced participants (EA MD: 1.5, BA: 1). Conclusion: Our easy access low-cost simulation model represents a feasible and tissue realistic training option to increase surgical performance of pediatric surgical trainees outside the OR.
RESUMEN
Introduction Anorectal malformations (ARM) affect 1 in 5,000 newborns with a wide range of defects. In the absence of a visible fistula, the diagnosis and classification of ARM require an augmented pressure distal colostogram. This procedure can be done after a diverting colostomy has been performed and implies exposing the child to radiation. We hypothesized that high-resolution transperineal ultrasound could correctly diagnose the type of ARM, thus sparing radiation exposure. Case Description Four full-term male newborns with ARM and no visible anal opening were referred to our center for further management. A diverting descendostomy was performed in the first 48 hours of life in all cases. Prior to the reconstructive surgery, we performed a high-resolution transperineal ultrasound with 3D tomographic reconstruction of the perineal region to assess the urethra, the rectum, and a possible fistula. Findings were compared with a conventional augmented pressure distal colostogram. The image acquisition was fast and did not cause any additional distress to the children. Conclusion In all cases the results of the distal colostogram nicely correlated with the high-resolution transperineal ultrasound with 3D tomographic reconstruction. In the future, we envision a time when it can potentially replace the distal colostogram in preoperative assessment of ARM with no distress and exposure to radiation.
RESUMEN
OBJECTIVE: The objective of this study was to analyze the feasibility and acceptance of a non-invasive, daily and proactive screening program for SARS-CoV-2 infection employing serial saliva testing, in combination with a digital questionnaire among healthcare providers (HCPs) in a multi-professional setting. DESIGN: This was a prospective cohort study involving HCPs from different units at a single tertiary care center, over a pilot phase of 4 weeks during the first wave of the COVID-19 pandemic from April 18th to June 6th, 2020. SETTING: Pediatric tertiary patient care units, Comprehensive Center for Pediatrics, Medical University of Vienna. SUBJECTS: HCPs from different units, including physicians, nurses, midwives, and administrative staff (with patient contact) were considered eligible for the study. Study participants were working in different settings in our center at varying levels of risk exposure. INTERVENTIONS: Saliva collection from mouth gargle and electronic symptom and exposure monitoring (eSEM) was performed by participants at the onset of each regular clinical shift (day or night shift), using an anonymous ID for matching the results. MEASUREMENTS: RT-PCR of all saliva samples, eSEM, as well as feasibility and acceptance thereof. RESULTS: Two hundred and seventy-five volunteers collected 1,865 saliva samples and responded 1,378 times in the eSEM during a 4-week period. 1,331 (96.7%) responses were that the testing was feasible and acceptable. The most common severe symptom during the 4-week period mentioned by HCPs was headache, reported 54 times (3.9%). Two SARS-CoV-2 positive samples-one of them being associated with symptoms-were identified. The acceptance rate among HCPs was 96.6%. CONCLUSION: Serial saliva screening was a well-accepted and feasible method for monitoring SARS-CoV-2 infectious state in health care professionals. Combination of regular SARS-CoV-2 tests with sequential saliva collection and storage could potentially represent a highly efficient strategy to identify and trace virus positive staff for employee and patient safety.
RESUMEN
INTRODUCTION: The correction of an anorectal malformation (ARM) is complex and relatively infrequent. Simulation training and subsequent assessment may result in better clinical outcomes. Assessment can be done using a competency assessment tool (CAT). This study aims to develop and validate a CAT for the posterior sagittal anorectoplasty (PSARP) on a simulation model. MATERIALS AND METHODS: The CAT-PSARP was developed after consultation with experts in the field. The PSARP was divided into five steps, while tissue and instrument handling were scored separately. Participants of pediatric colorectal hands-on courses in 2019 and 2020 were asked to participate. They performed one PSARP procedure on an ARM simulation model, while being assessed by two objective observers using the CAT-PSARP. RESULTS: A total of 82 participants were enrolled. A fair interobserver agreement was found for general skills (intraclass correlation coefficient [ICC] = 0.524, p < 0.001), a good agreement for specific skills (ICC = 0.646, p < 0.001), and overall performance (ICC = 0.669, p < 0.001). The experienced group scored higher on all steps (p < 0.001), except for "anoplasty (p = 0.540)," compared with an inexperienced group. CONCLUSION: The CAT-PSARP is a suitable objective assessment tool for the overall performance of the included steps of the PSARP for repair of an ARM on a simulation model.

BACKGROUND/PURPOSE: The anal sphincter complex (ASC) plays a key role in continence and is often dysfunctional in infants born with anorectal malformations (ARM). The ASC is well depicted by magnetic resonance (MR) imaging but volumetric reference data are lacking in infants. Thus, we tested the feasibility of MR based ASC volumetry, collected reference data, and compared them with cases of favorableprognosis and unfavorable prognosis (as defined by the type of ARM). METHODS: We determined ASC volume on T2 weighted MR images of seventy six infants (ARM n = 33; controls n = 43) by manual segmentation. Inter operator agreement was assessed by intraclass correlation coefficient. Linear regression was used to establish weight dependent reference data. Observed to expected ASC volumes of patients with unfavorable and favorable prognosis were compared (unpaired t test). RESULTS: ASC volumetry was feasible in all cases. Patients with ARM had low 'observed to expected' ASC volume ( 18.1%; p = 0.006). 'Observed to expected' ASC volume differed significantly between patients with favorableand unfavorable prognosis (p < 0.001). CONCLUSION: We confirmed the feasibility of MRI based ASC volumetry and provided initial reference data for infants. Although ASC volumes were lowest in infants with ARM of unfavorable prognosis for fecal continence, the value of ASC volume as prognostic parameter remains to be determined.

INTRODUCTION: An anorectal malformation (ARM) is a congenital malformation that requires surgical correction. To acquire the skills needed to perform this complex procedure, an affordable simulation model has previously been developed and validated. The aim of this study is to evaluate the suitability of this ARM model (with perineal fistula) for training in hands-on workshops. MATERIALS AND METHODS: The ARM model consists of a wooden casing with disposable perineal body. Participants in several international pediatric colorectal hands-on workshops in 2019 and 2020 were asked to participate. They were divided in a target group and an experienced group based on experience. All practiced the posterior sagittal anorectoplasty procedure on the model with multimodality guidance. Subsequently, statements on the suitability of the model for use during hands-on workshops were scored on a 5-point Likert scale. RESULTS: A total of 80 participants were included (43 surgical specialists, 13 pediatric surgery fellows, and 25 residents). Nearly, all statements scored at least a mean of >4.0, all scored significantly better than a neutral opinion. The target group (n = 58) scored higher compared with the experienced group (n = 22) on "transferability of the skills to the clinical setting" (means 4.4 vs. 4.0, p = 0.038); however, the "suitability as a replacement for an animal model" scored significantly lower (means 3.6 vs. 3.9, p = 0.049). No other differences were found. CONCLUSION: This affordable ARM model was regarded a suitable model for training during preclinical hands-on workshops and could be used for the specified steps of the procedure.

INTRODUCTION: For the classification of the complexity of cloacal malformations and the decision on the operative approach, an exact anatomical assessment is mandatory. To benefit from using three-dimensional (3D)-printed models in preoperative planning and training, the practicability of these models should be guaranteed. The aim of this study was to evaluate the quality and feasibility of a real-size 3D-printed cloaca model for the purpose of cysto-vaginoscopic evaluation. MATERIALS AND METHODS: We performed a 3D reconstruction and printed a real-size, rubber-like 3D model of an infant pelvis with a cloacal malformation and asked invited pediatric surgeons and pediatric urologists to perform a cysto-vaginoscopy on the model and to complete a brief questionnaire to rate the quality and feasibility of the model and to indicate whether they would recommend the model for preoperative planning and training. RESULTS: Overall, 41 participants rated the model quality as good to very good (M = 3.28, standard deviation [SD] = 0.50, on a scale from 1 to 4). The model was rated as feasible for preoperative training (M = 4.10, SD = 0.75, on a scale from 1 to 5) and most participants (85.4%) would recommend the model for preoperative training. The cysto-vaginoscopy of the model was considered as a valid training tool for real-life cases and improved the confidence on the anatomy of a cloaca. CONCLUSION: The results of our study indicate that patient-specific 3D-printed models might be a useful tool in the preoperative evaluation of complex anorectal malformations by simulation of cysto-vaginoscopy with an excellent view on anatomical structures to assess the whole spectrum of the individual cloacal malformation. Our model might be a valuable add-on tool for specialty training in pediatric colorectal surgery.

INTRODUCTION: In patients with anorectal malformations (ARM), the sacral ratio (SR) serves as an established predictive marker for functional prognosis and is derived from conventional radiographs. More recently, magnetic resonance imaging (MRI) has emerged as a diagnostic alternative for preoperative/baseline assessment of patients with ARM. With this study we aimed to evaluate if the SR could be reliable be measured from MRI images and if it correlated to SR measurements obtained from radiographs. METHODS: Two raters analyzed MRI data and conventional radiographs from thirty-one subjects (n = 17 with ARM; n = 14 controls). We calculated intra-class correlation coefficients (ICCs) to test inter-rater reliability and applied paired t-tests to examine if SR parameters from MRI were comparable with those from pelvic radiograph. We further computed Pearson's correlation coefficients to test the linear relationship between SR calculated from MRI and conventional radiographs. RESULTS: The ARM and control groups did not statistically differ in their age and weight on the day of the MRI scan. Reliability analysis revealed an excellent inter-rater agreement for SR from radiograph parameters with an intraclass correlation coefficient (ICC) of 0.94, respectively of 0.86 for MRI (frontal plane), and of 0.84 for MRI (sagittal plane). The correlation coefficient between SR calculated from the sagittal MRI and SR calculated from radiograph images was significant and high (r = 0.80, P < 0.001). The SRs from MRI images did not significantly differ from SRs from radiographs, but were also not statistically equivalent. CONCLUSION: Our results demonstrate that the SR can be derived from MRI images with good inter-rater reliability. The SR value is marginal higher when calculated on MRI, presumably due to inclusion of cartilaginous yet unossified structures.

INTRODUCTION: Short-term international medical service trips (MSTs) provide specialized care in resource-constrained countries. There are limited data on immediate and long-term reported outcomes following specialty MST. We hypothesized that dedicated collaborative MST team and host institution produce outcomes and results comparable to those of high-income settings. Our primary aim was to analyze the long-term surgical and functional outcomes of our specialty-specific MSTs following five years of annual MST in Honduras. METHODS: We performed a single-institution retrospective analysis of 56 children who underwent colorectal and pelvic reconstructive operations between 2014 and 2018. Demographics, diagnosis, comorbidities, type of repair, long-term complications, and functional bowel and bladder results were recorded. RESULTS: We included a total of 56 children, 47 with ARM and 9 with HD, with a median age of 43.5â¯months (17-355) at the time of surgery. 25% (22) of the patients were lost to follow-up. Fecal continence was achieved by 23 (60%) patients <5â¯years who reported toilet training (nâ¯=â¯39) and by 5 (45%) patients >5â¯years (nâ¯=â¯11). Complications included constipation in 18 (42.9%) children with ARM and in 1 (12.5%) with HD. Eleven (19.6%) patients required revisional surgery for skin level anal stricture. Seventy-five percent of the patients with pediatric colorectal disorders attending the MST were compliant with continued long-term follow-up. CONCLUSION: We were able to demonstrate that with organized, dedicated site and surgeon, results achieved can be comparable to those in the high-income countries (HICs). We conclude that this type of specialized care is feasible and beneficial for affected pediatric colorectal patients in resource-limited settings, when a strong partnership with a system of preoperative assessments and peri- and postoperative care can be established. LEVEL OF EVIDENCE: Level IV (retrospective cohort study).

Soiling and fecal incontinence are troubling complications which can occur after a pull-through for Hirschsprung disease. They can usually be improved with proper medical management, but in some cases are the result of an anatomic defect related to overstretching of the sphincters and/or damage of the anal canal. For such patients the treatment of this true fecal incontinence is limited to a structured bowel management program with ante- or retrograde enemas to achieve social continence. Herein we report two such patients with overstretched sphincters and loss of the dentate line after an initial pull-through and describe a sphincter tightening technique to improve bowel control.

Introduction: Short-term international medical service trips (MST) are established means to access specialized medical aid in resource-limited areas. The field of pediatric colorectal surgery is a subspecialty in pediatric surgery that mainly treats anorectal malformations (ARM) and Hirschsprung disease (HD). This study aimed to investigate the impact of MST on the donors' perception of competency concomitantly to the impact on patients in the donors' home country. We also wanted to investigate whether the donors' pre-existing experience in the field of ARM and HD affects the experience they gain during the MST, and the subjective perception in treating patients in their base country. Methods: We created a questionnaire for the international medical staff participating in MSTs on the unique topic of pediatric colorectal diseases. The questionnaire was split into three parts: essential experience (1) in the field of colorectal surgery of the participant, the experience and impact on patient care in the home country during and after the MST in ARM (2), and in HD (3). Results: We collected data from 20 participants (6 female, 14 male). The majority of them had prior experience with the MST program (75%) and came from institutions specialized in the treatment of pediatric colorectal disorders (80%). Participants felt that MST improved patient care in both the host country (p < 0.001) and their home country (p < 0.001). Experienced and less experienced participants did not differ in the overall MST evaluation (ps > 0.08). They reported that their competencies to treat ARM and HD improved significantly in response to the MST (ps < 0.001). Improvements in ARM and HD treatment were associated with the number of supervised HD surgeries during MST, while the other forms of participation were unrelated to the improvements. Conclusion: The results of our questionnaire indicate that participation in MST in the specialized field of pediatric colorectal surgery helps to improve confidence in the care and treatment of affected patients in both the host and donor countries, independent of previous surgical experience.

Introduction: Training in laparoscopic surgery seems to be an important aspect in gaining and maintaining professional competency. In experimental settings, camera navigation skills improved after simulation-based training, but the effect of camera work on the surgeon's performance is not well studied. The aim of this study was to investigate whether a fixed camera or an operated camera, as well as the experience of the camera operator has an effect on the performance of the surgeon. Materials and Methods: The study was performed on the LapSim laparoscopic training system. The task was to tie an intracorporal knot in a static surgical environment with three different camera conditions: fixed camera, camera operated by an inexperienced person (inexpert camera), and camera operated by an experienced surgeon (expert camera). The camera conditions were counterbalanced across trials. Performance variables were completion time in seconds and the extend of movements in path length and angular pathway. Gaze behavior was measured with eye-tracking glasses worn by the surgeon as well as the camera operator and was evaluated for performance-harming effects. Results: Completion time varied across conditions, with participants performing significantly longer in the fixed camera condition than in the expert or the inexpert condition. The expert and inexpert conditions did not differ. The performance-harming effect of non-focusing on the tissue was especially visible in the fixed camera condition but disappeared in the expert camera condition. Neither the camera operators' gaze behavior nor the surgeon-camera operator fixation agreement predicted task performance. Discussion: A camera operator can potentially eliminate performance-harming effects of maladaptive gaze behavior and promote optimal visual behavior of a surgeon. In our experimental task, there was no significant difference in whether the camera operator had previous training in laparoscopic surgery or not.

BACKGROUND/PURPOSE: We conduct an annual medical mission to Hospital Ruth Paz para Niños Quemados y Cirugía Pediátrica in Honduras to operate on cases of anorectal malformations (ARM). To improve our knowledge of these patients, we compared their health-related quality of life (HRQoL), and the health literacy of their caregivers from this hospital and ours in the United States. METHODS: The BRIEF Health Literacy Screen (BHLS) and Pediatric Quality of Life Inventory 4.0 (PedsQL) were used, respectively, to assess the health literacy and HRQoL of their guardians. All patients scheduled for an ARM-related operation in October 2016 were eligible for inclusion, and a matched population was selected in Nationwide Children's Hospital, Columbus, Ohio. RESULTS: The sample comprised 127 patients, with 22 from Honduras and 105, the US. About 13.6% and 80% of Honduran and American caregivers, respectively, had adequate literacy. Honduran and American caregivers of patients aged 12 months and below rated the HRQoL of their children at 87 and 82, respectively; aged between two and four years, at 84 and 77; aged between two and four years, at 85 and 79; and of teens, at 59 and 66. For adults, the rate was 71 and 77 in Honduras and the US, respectively. CONCLUSION: Although health literacy is extremely low in the Honduran group, its HRQoL was comparable to that of its American counterpart. Improving health literacy by educating caregivers could be an additional goal for medical missions in the future. LEVEL OF EVIDENCE: Level III.

PURPOSE: Objective cosmetic analysis is important to evaluate the cosmetic outcome after breast surgery or breast radiotherapy. For this purpose, we aimed to improve our recently developed objective scoring software, the Breast Analyzing Tool (BAT®). METHODS: A questionnaire about important factors for breast symmetry was handed out to ten experts (surgeons) and eight non-experts (students). Using these factors, the first-generation BAT® software formula has been modified and the breast symmetry index (BSI) from 129 women after breast surgery has been calculated by the first author with this new BAT® formula. The resulting BSI values of these 129 breast cancer patients were then correlated with subjective symmetry scores from the 18 observers using the Harris scale. The BSI of ten images was also calculated from five observers different from the first author to calculate inter-rater reliability. In a second phase, the new BAT® formula was validated and correlated with subjective scores of additional 50 women after breast surgery. RESULTS: The inter-rater reliability analysis of the objective evaluation by the BAT® from five individuals showed an ICC of 0.992 with almost no difference between different observers. All subjective scores of 50 patients correlated with the modified BSI score with a high Pearson correlation coefficient of 0.909 (p < .001) which was better compared to the old software (r = 0.769; p < .001). CONCLUSIONS: The modified BAT® software improves the correlation between subjective and objective BSI values, and may be a new standard for trials evaluating breast symmetry.

OBJECTIVE: To determine the attitude of referring pediatricians towards the decision of treatment modalities for undescended testis (UDT) in neurologic impaired boys (NIB). METHODS AND MATERIALS: An online questionnaire was offered to registered pediatricians in Austria and Germany for online completion. RESULTS: 221 male (61.6%) and 138 female (38.4%) pediatricians completed the survey; 326 (90.8%) believe that UDT should be treated according to national guidelines; 31 (8.6%) believe that UDT should be treated according to the parental wish, whereas only 2 (0.6%) tend to no treatment at all. Tumor prophylaxis, further sexual life, legal concerns, risks of anesthesia, and the choice of the parents have major impact on the perception of UDT. Moreover, fertility and limited life expectancy seem to be of minor importance only. In general, Pearson χ2 test could not identify age and sex of pediatricians as significant predictor of how the importance of the treatment of UDT is appraised. CONCLUSION: From the pediatric point of view UDT in NIB is an important issue and should be treated according to guidelines. Nevertheless, this study indicates the problems in decision-making and choosing the best management for UDT in NIB. Undoubtedly, further ethical discussion is needed to optimize treatment of UDT in NIB.

BACKGROUND: Hypospadias is a challenging field of urogenital reconstructive surgery, with different techniques currently being used. OBJECTIVE: Evaluate international trends in hypospadias surgery. DESIGN, SETTING, AND PARTICIPANTS: Paediatric urologists, paediatric surgeons, urologists, and plastic surgeons worldwide were invited to participate an anonymous online questionnaire (http://www.hypospadias-center.info). MEASUREMENTS: General epidemiologic data, preferred technique in the correction of hypospadias, and preferred technique in the correction of penile curvature were gathered. RESULTS AND LIMITATIONS: Three hundred seventy-seven participants from 68 countries returned completed questionnaires. In distal hypospadias (subcoronal to midshaft), the tubularised incised plate (TIP) repair is preferred by 52.9-71.0% of the participants. Meatal advancement and glanuloplasty (MAGPI) is still a preferred method in glandular hypospadias. In the repair of proximal hypospadias, the two-stage repair is preferred by 43.3-76.6%. TIP repair in proximal hypospadias is used by 0.9-16.7%. Onlay flaps and tubes are used by 11.3-29.5% of the study group. Simple plication and Nesbit's procedure are the techniques of choice in curvature up to 30°; urethral division and ventral incision of the tunica albuginea with grafting is performed by about 20% of the participants in severe chordee. The frequency of hypospadias repairs does not influence the choice of technique. CONCLUSIONS: In this study, we identified current international trends in the management of hypospadias. In distal hypospadias, the TIP repair is the preferred technique. In proximal hypospadias, the two-stage repair is most commonly used. A variety of techniques are used for chordee correction. This study contains data on the basis of personal experience. However, future research must focus on prospective controlled trials.

UNLABELLED: Two programs were recently developed for the aesthetic evaluation of results in breast cancer conservative treatment: the Breast Cancer Conservative Treatment cosmetic results (BCCT.core) and the Breast Analyzing Tool (BAT). Both make use of a face-only photographic view of the patient and were developed to overcome the lack of reproducibility observed with subjective visual evaluation. The BCCT.core analyses several parameters related to asymmetry, color differences and scar appearance, while the BAT considers only asymmetry measurements. The purpose of this study was to compare the performance of these two methods. MATERIAL AND METHODS: Digital pictures of 59 patients from Porto and 60 from Vienna were evaluated subjectively by two panels using the four-class Harris scale. The Porto photographs had a similar backlight and better quality, and were evaluated by an international panel of 23 experts. The Vienna photographs had different backlight and lower quality, and were evaluated by four students and two breast cancer specialists. All 119 cases were submitted to analysis using the BCCT.core and BAT. Agreement between the software programs and the subjective evaluation was calculated using kappa (k), weighted kappa statistics (wk) and error rate (er). RESULTS: In overall analysis, BCCT.core program obtained a better agreement with the subjective evaluation (k = 0.56; wk = 0,64; er = 0.20) than the BAT software (k = 0.39; wk = 0.46; er = 0.42) (P < 0.0007). Results were again better for the BCCT.core program, when analysing the photographs obtained in Porto (k = 0.71; wk = 0.78; er = 0.14) than for the BAT (k = 0.35; wk = 0.41; er = 0.51) (P < 0.0003) while no significant differences in agreement were obtained regarding the Vienna images (P > 0.1). CONCLUSIONS: The results suggest that the inclusion of multiple parameters in image analyses of aesthetic results has the potential to improve results. However, picture quality is probably important for analysis of other features besides asymmetry.
