Abstract
BACKGROUND Colonization of near-patient surfaces in hospitals plays an important role as a source of healthcare-associated infections. Routine disinfection methods only result in short-term elimination of pathogens. AIM To investigate the efficiency of a newly developed antimicrobial coating containing nanosilver in long-term reduction of bacterial burden in hospital surfaces to close the gap between routine disinfection cycles. METHODS In this prospective, double-blinded trial, frequently touched surfaces of a routinely used treatment room in an emergency unit of a level-I hospital were treated with a surface coating (nanosilver/DCOIT-coated surface, NCS) containing nanosilver particles and another organic biocidal agent (4,5-dichloro-2-octyl-4-isothiazolin-3-one, DCOIT), whereas surfaces of another room were treated with a coating missing both the nanosilver- and DCOIT-containing ingredient and served as control. Bacterial contamination of the surfaces was examined using contact plates and liquid-based swabs daily for a total trial duration of 90 days. After incubation, total microbial counts and species were assessed. FINDINGS In a total of 2880 antimicrobial samples, a significant reduction of the overall bacterial load was observed in the NCS room (median: 0.31 cfu/cm2; interquartile range: 0.00-1.13) compared with the control coated surfaces (0.69 cfu/cm2; 0.06-2.00; P < 0.001). The nanosilver- and DCOIT-containing surface coating reduced the relative risk of a critical bacterial load (defined as >5 cfu/cm2) by 60% (odds ratio 0.38, P < 0.001). No significant difference in species distribution was detected between NCS and control group. CONCLUSION Nanosilver-/DCOIT-containing surface coating has shown efficiency for sustainable reduction of bacterial load of frequently touched surfaces in a clinical setting.

Abstract
BACKGROUND Frontal sinus median drainage according to Draf is an established procedure for achieving maximum drainage of the frontal sinus. Despite great efforts and several modifications, restenosis of the neo-ostium is still a persistent problem. This study presents an approach by implementing local mucosal flaps to prevent restenosis and compares it with the conventional technique without using the flap. METHODS Description of endonasal, lateral pedicle mucosal flap. A Draf III procedure was performed on 156 patients between 2012 and 2021. Data for 123 of the included patients were retrospectively analyzed in terms of surgical indication, technique, postoperative aftercare and patency of the drainage pathway. The follow-up observation period was between 3 and 24 months. RESULTS Treatment with the pedicle mucosal flap took place in 86 cases. 37 patients were treated as a control group without this flap. The analysis showed a significant association to the event "total closure of the drainage pathway" for surgical technique, as well as in the case of the presence of an allergy and the existence of Samter's triad. Furthermore, there was a significant association between the onset of "near total closure of the frontal sinus ostium" and Samter's triad, CRS and revision surgery was involved. CONCLUSIONS Use of an endonasal lateral pedicle flap for reconstruction of mucosal defects in frontal sinus surgery improves the long-term chances of a patent drainage pathway. Bone exposed by drilling was covered with a local mucosal flap for a faster epithelialization, healing and less scarring.

Abstract
BACKGROUND Neovascular age-related macular degeneration (nAMD) is the most frequent cause of pigment epithelial detachment (PED). In the clinical routine the treatment of fibrovascular PED (fPED) and serous vascularized PED (svPED) with intravitreal vascular endothelial growth factor (VEGF) inhibitors has a restricted prognosis. OBJECTIVE There are limited data on the long-term outcome of PED under anti-VEGF therapy. Therefore, this study recorded the course of treated PEDs in nAMD eyes over a period of 5 years. METHODS All eyes with fPED or svPED that underwent anti-VEGF medication between 2006 and 2015 were retrospectively analyzed regarding the clinical course and the morphology seen on optical coherence tomography (OCT). The inclusion criteria were the detection of a PED on OCT, the angiographic verification of nAMD, a documented clinical history over 5 years and a good image quality. RESULTS A total of 23 eyes from 22 patients met the inclusion criteria. After 5 years a significant deterioration of visual acuity (VA) was seen in all eyes (p = 0.007) and in the subgroup of cases with fPED (p = 0.045). In the eyes with svPED the decline of VA was not significant (p = 0.097). In the collective study group a statistically significant reduction of PED height (p = 0.006) and an increase of PED diameter was measured (p = 0.002). In the subgroup analysis the decrease of PED height and increase of PED diameter were significant for cases with svPED (p = 0.004, p = 0.013, respectively) but were not statistically significant for fPED eyes (height: p = 0.616; diameter: p = 0.097). In 17 (74%) eyes fibrosis or atrophy were seen on the final assessment of OCT images. DISCUSSION After 5 years of anti-VEGF therapy for nAMD-associated PED the VA declined in half of the eyes and the OCT showed an unfavorable morphology in 3/4 of the cases. The average number of visits and injections was distinctly lower than in clinical trials and other real-life analyses. In summary, we observed an undertreatment with a worse functional and anatomical outcome in our clinical routine compared to other studies.

Abstract
Abstract
Background
Arrhythmias may often be a result of heart failure, but they can also cause left-ventricular systolic dysfunction (LVSD), thereby presenting as arrhythmia-induced cardiomyopathy (AIC). AIC-diagnosis is established retrospectively when LVSD normalizes or improves significantly over time following rhythm restoration. However, the prevalence and most importantly the time course of this relevant disease remain unclear and hence merit investigation to enable the correct diagnosis.
Purpose
Therefore, our aim was to evaluate a) the occurrence of AIC in this clinical relevant cohort of patients with newly diagnosed and otherwise unexplainable LVSD and concomitant tachycardia and b) the time needed to fulfill the diagnostic criteria of AIC in order to facilitate a diagnostic algorithm.
Method
We prospectively screened patients hospitalized for newly diagnosed and otherwise unexplainable LVSD (i.e. left ventricular ejection fraction (LVEF) <50%) and coexisting tachyarrhythmia (atrial fibrillation/flutter + heart rate (HR) >100/min) in 3 cardiological centers. Coronary angiography and cardiac magnetic resonance imaging were performed to exclude other causes for LVSD. Patients underwent a rhythm control strategy in accordance to the local clinical pathways. LVEF was assessed by echocardiography at presentation and at follow-up (FU) visits after 2, 4, and 6 months. Patients who lost sinus rhythm (SR) during FU were excluded. Patients with any increase of ≥15% in absolute EF or an EF ≥50% with an improvement of ≥10% after 6 months of FU were assigned to the AIC-group, which is a common definition of AIC. All others were assigned to an idiopathic DCM-group as final comparator.
Results
68 patients were eligible, 18 of them were excluded: 1 lost to follow-up, 1 PCI, 2 COVID-19, 1 diagnosed cancer, 1 withdraw consent and 12 lost SR. Thus, our sample consists of a total of 50 patients. At presentation, mean±SD HR was 121±17/min. After rhythm therapy, HR normalized (67±10/min) and LVEF increased in both groups, see fig. 1. Surprisingly, only 9 patients did not fulfill the AIC-criteria in this specific collective resulting in a prevalence of 82% (95%-CI: 68% – 92%). This high prevalence of AIC underlines the importance of the disease. 2 and 4 months after rhythm intervention, 58% and 73% of patients fulfilled AIC-criteria (fig. 2). The sensitivity for detection of AIC by echocardiographic LVEF-measurement at months 2 and 4 of FU was 65% and 86% with a specificity of 100%, emphasizing that a FU of 6 months is necessary to certainly distinguish between AIC and idiopathic DCM.
Conclusion
The prevalence of AIC in patients with newly diagnosed and otherwise unexplainable LVSD with concomitant tachycardia is 82%. Analysis of the time course of AIC clearly suggests that the final diagnosis cannot be established before 6 months after successful rhythm restoration. These results may help to improve diagnosis of AIC in daily clinical practice.

Abstract
Purpose Photodynamic diagnosis and white-light TURB with adjuvant intravesical chemotherapy (ICT) is widely used in treatment of bladder cancer. This non-inferiority trial is designed to demonstrate non-inferiority regarding recurrence-free survival (RFS) of Hexvix® TURB followed by immediate instillation compared to white-light TURB with immediate instillation followed by maintenance ICT. Methods Between 07/2010 and 12/2016, 129 patients with EORTC intermediate risk non-muscle invasive bladder cancer treated with TURB were included in this multicentre phase III study. Patients were randomized and received either white-light TURB with immediate ICT followed by maintenance ICT (n = 62, 20 mg Mitomycin weekly for 6 weeks as induction phase, afterwards 20 mg/month for 6 months) or Hexvix® TURB with immediate ICT only (n = 67, 40 mg Mitomycin). Primary study endpoint was RFS after 12 months. Hexvix® TURB was counted as non-inferior to white light alone if the upper limit of the one-sided 95% confidence interval of hazard ratio was lower than 1.676. Due to the non-inferiority design, the per-protocol population was used as the primary analysis population (n = 113) Results Median follow-up was 1.81 years. Hexvix® group showed more events (recurrence or death) than white-light group (19 vs. 10) resulting in a HR of 1.29 (upper limit of one-sided 95%-CI = 2.45; pnon-inferiority = 0.249). The ITT population yielded similar results (HR = 1.67); 3.18], pnon-inferiority = 0.493). There was no significant difference in overall survival between both groups (p = 0.257). Conclusion Non-inferiority of Hexvix® TURB relative to white-light TURB with maintenance Mitomycin instillation in intermediate risk urothelial carcinoma of the bladder was not proven. Hence a higher effect of maintenance ICT is to assume compared to a Hexvix®-improved TURB only, confirming its important role in patient treatment.

Abstract
OBJECTIVE Over the past decade numbers of bilateral mastectomy have increased steadily. As a result, bilateral breast reconstruction is gaining popularity. The presented study compares complications and outcomes of unilateral and bilateral DIEP free-flap breast reconstructions using the largest database available in Europe. METHODS Female breast cancer patients (n = 3926) receiving DIEP flap breast reconstructions (n = 4577 free flaps) at 22 different centers were included in this study. Free flaps were stratified into two groups: a unilateral- (UL) and a bilateral- (BL) breast reconstruction group. Groups were compared with regard to surgical complications and free flap outcome. RESULTS Mean operative time was significantly longer in the BL group (UL: 285.2 ± 107.7 vs. BL: 399.1 ± 136.8 min; p < 0.001). Mean ischemia time was comparable between groups (p = 0.741). There was no significant difference with regard to total (UL 1.8% vs. BL 2.6%, p = 0.081) or partial flap loss (UL 1.2% vs. BL 0.9%, p = 0.45) between both groups. Rates of venous or arterial thrombosis were comparable between both groups (venous: UL 2.9% vs. BL 2.2%, p = 0.189; arterial: UL 1.8% vs. BL 1.2%, p = 0.182). However, significantly higher rates of hematoma at the donor and recipient site were observed in the UL group (donor site: UL 1.1% vs. BL 0.1%, p = 0.001; recipient site UL 3.9% vs. BL 1.7%, p < 0.001). CONCLUSIONS The data underline the feasibility of bilateral DIEP flap reconstruction, when performed in a setting of specialized centers.

Abstract
INTRODUCTION Several patient-related factors have been identified with regard to the safety and efficacy of breast reconstructions. This study analyzed the largest series of microsurgical breast reconstructions in Germany using deep inferior epigastric perforator (DIEP) flaps, with a focus on the impact of patient body mass index (BMI). PATIENTS AND METHODS A total of 3911 female patients underwent 4561 free DIEP flap breast reconstructions across 22 different centers. The cases were divided into five groups using World Health Organization BMI criteria: underweight group (BMI <18.5 kg/m2), normal weight/ control group (BMI: 18.5-24.9 kg/m2), overweight group (BMI: 25-29.9 kg/m2), moderately obese group (BMI: 30-34.9 kg/m2), and severely obese group (BMI ≥ 35 kg/m2). Surgical complications were accounted for and the five BMI groups were then compared. RESULTS Overall, there was no significant difference regarding the rate of partial- and total flap loss between all BMI groups (p > 0.05). However, overweight and obese patients showed significantly higher rates of postoperative infections at the donor and recipient sites than the control group (donor site infections: overweight 0.6%; moderately obese 0.9%; severely obese 2.4% vs control 0.1%; all p<0.01; recipient site infections: overweight 0.5%; moderately obese 0.8%; severely obese 1.4% vs control 0.1%; all p < 0.05). The rate of medical complications also differed significantly between groups, with the highest rates in moderately and severely obese women (moderately obese: 8.4%; severely obese: 13.0% vs. control: 5.1%; p < 0.01). CONCLUSION Our findings suggest that successful free tissue transfer can be achieved even in an underweight and severely obese population with acceptable risk for complications.

Abstract
We developed a time-efficient semi-automated axon quantification method using freeware in human cranial nerve sections stained with paraphenylenediamine (PPD). It was used to analyze a total of 1238 facial and masseteric nerve biopsies. The technique was validated by comparing manual and semi-automated quantification of 129 (10.4%) randomly selected biopsies. The software-based method demonstrated a sensitivity of 94% and a specificity of 87%. Semi-automatic axon counting was significantly faster (p < 0.001) than manual counting. It took 1 hour and 47 minutes for all 129 biopsies (averaging 50 sec per biopsy, 0.04 seconds per axon). The counting process is automatic and does not need to be supervised. Manual counting took 21 hours and 6 minutes in total (average 9 minutes and 49 seconds per biopsy, 0.52 seconds per axon). Our method showed a linear correlation to the manual counts (R = 0.944 Spearman rho). Attempts have been made by several research groups to automate axonal load quantification. These methods often require specific hard- and software and are therefore only accessible to a few specialized laboratories. Our semi-automated axon quantification is precise, reliable and time-sparing using publicly available software and should be useful for an effective axon quantification in various human peripheral nerves.

Abstract
Background So far only single cases with short follow-up have been reported on the use of intravitreal anti-VEGF for traumatic choroidal neovascularizations (CNV). This paper reports a large case series of patients with CNV secondary to choroidal rupture after ocular trauma receiving intravitreal anti-VEGF (vascular endothelial growth factor) injections. Methods Fifty-four patients with unilateral choroidal rupture after ocular trauma diagnosed between 2000 and 2016 were retrospectively evaluated. Eleven patients with CNV secondary to choroidal rupture were identified. Five eyes with traumatic secondary CNV were treated with anti-VEGF and were systematically analysed. The other 4 patients with inactive CNV underwent watchful observation. Results Four men and one woman with a mean age of 29 years (SD 12.4; range 19–45) had intravitreal anti-VEGF therapy for traumatic CNV. Another 4 patients with a mean age of 37 years (SD 6.6; range 31–46) presented with inactive CNV and did not receive specific treatment. In all 9 cases the mean interval between the ocular trauma and the diagnosis of CNV was 5.7 months (SD 4.75; range 2–12). In the treatment group per eye 4.2 injections (SD 3.2; range 1–8) were given on average. Four eyes were treated with bevacizumab and one eye with ranibizumab. Regression of CNV was noted in all eyes. In 4 eyes visual acuity (VA) improved, one eye kept stable visual acuity. Conclusions Here, we present the up to now largest case series of traumatic CNV membranes treated with anti-VEGF injections with a mean follow-up period of 5 years. Intravitreal anti-VEGF therapy seems to be safe and effective for secondary CNV after choroidal rupture. Compared to exudative age-related macular degeneration fewer injections are needed to control the disease. Trial registration Retrospective registration with local ethics committee on 21 March 2019. Trial registration number is 19-1368-104.

Abstract
BACKGROUND Currently only few data are available on a direct comparison of the treatment reality with ranibizumab and aflibercept in patients with diabetic macular edema (DME). This study assessed best corrected visual acuity (BCVA) outcomes and central retinal thickness (CRT) under treatment with ranibizumab and aflibercept. MATERIAL AND METHODS Patients with DME involving the fovea in treatment-naïve eyes and a follow-up period of least 12 months were retrospectively identified. Patients underwent treatment with ranibizumab 0.5 mg or aflibercept 2.0 mg. The findings were obtained using clinical examination, fluorescein angiography and spectral domain optical coherence tomography (SD-OCT, measuring CRT). RESULTS A total of 41 treatment-naïve eyes were identified in 29 patients with DME involving the fovea. The mean 12-month improvement was +9.5 letters in 19 eyes treated with ranibizumab and BCVA improving from 0.57 log MAR (95% confidence interval, CI 0.45-0.70 log MAR) to 0.38 log MAR (95% CI 0.25-0.50 log MAR; p < 0.001) and +8.5 letters in the aflibercept group with 22 eyes and BCVA improving from 0.38 log MAR (95% CI 0.25-0.51 log MAR) to 0.21 log MAR (95% CI 0.08-0.34 log MAR; p < 0.001). The difference between the two groups was not statistically significant (p = 0.599). When the initial visual acuity was 0.4 or less, the mean BCVA improved in 14 eyes treated with ranibizumab from 0.62 log MAR (95% CI 0.47-0.79 log MAR) to 0.38 log MAR (95% CI 0.21-0.55 log MAR), an improvement of 12.0 letters (p < 0.001), in 11 eyes treated with aflibercept from 0.63 log MAR (95% CI 0.42-0.84 log MAR) to 0.29 log MAR (95% CI 0.08-0.50 log MAR), an improvement of 17.0 letters (p < 0.001). The difference between the two groups was significant (p < 0.001). The mean number of intravitreal injections was 6.4 (95% CI 5.1-7.7) in the ranibizumab group, 7.5 (95% CI 6.2-8.8) in the aflibercept group (p = 0.199). The mean CRT decreased significantly (p < 0.001) in patients treated with both ranibizumab and aflibercept without any evidence of a significant difference between the two groups (p = 0.514). DISCUSSION In the patients studied ranibizumab and aflibercept showed a good safety and efficacy in the treatment of DME regarding BCVA and CRT under real-life conditions after 12 months. In cases of lower initial visual acuity (0.4 or 20/50 or less) aflibercept was more effective at improving vision.

Abstract
PURPOSE Bone block augmentation from the iliac crest can be used for reconstruction of the osteochondral unit to restore the underlying subchondral bone upon restoration of the cartilaginous layer via matrix-induced chondrocyte transplantation. To critically understand the successful restoration of the defect, biomechanical and histological analysis of the implanted bone blocks is required. The aim of the study was to analyse the ability of the bone block technique to restore huge bone defects by mimicking the physiological subchondral zone. METHODS The experiments were performed using lateral femoral condyles and iliac crest bone grafts from the same cadavers (n = 6) preserved using the Thiel method. CT scans were made to evaluate bone pathology. Bone mineral density of all specimens was evaluated in the femoral head prior to testing. A series of tests were conducted for each pair of specimens. A static compression test was performed using an electro dynamic testing machine with maximal strength and failure behavior analyzed. Biomechanical tests were performed in the medial-lateral direction for iliac crest and for femoral condyles with and without removal of the cartilage layer. Histological analysis was performed on decalcified specimens for comparison of the condyle at lesion site and the graft. RESULTS No significant difference in failure load could be found for iliac crest (53.3-180.5 N) and femoral condyle samples upon cartilage removal (38.5-175.1 N) (n.s.). The femoral condyles with an intact cartilage layer showed significantly higher loads (118.3-260.4N) compared to the other groups indicating that native or regenerated cartilage can further increase the failure load (p < 0.05). Bone mineral density significantly influenced failure load in all study groups (p < 0.05). Histological similarity of the cancellous bone in the femoral condyle and in the iliac crest was observed. However, within the subchondral zone, there was a higher density of sponge like organized trabeculae in the bone samples from the iliac crest. Tide mark was only detected at the osteochondral interface in femoral condyles. CONCLUSION This study demonstrated that, bone blocks derived from the iliac crest allow a biomechanical appropriate and stable restoration of huge bony defects by resembling the subchondral zone of the femoral condyle. Therefore, bone augmentation from the iliac crest combined with matrix-induced autologous chondrocyte transplantation seems to be a reasonable method to treat these challenging injuries.

Abstract
Objective To evaluate the influence of an active inflammatory process in the liver on Gd-EOB-DTPA-enhanced MR imaging in patients with different degrees of fibrosis/cirrhosis. Material and methods Overall, a number of 91 patients (61 men and 30 women; mean age 58 years) were included in this retrospective study. The inclusion criteria for this study were Gd-EOB-DTPA-enhanced MRI of the liver and histopathological evaluation of fibrotic and inflammatory changes. T1-weighted VIBE sequences of the liver with fat suppression were evaluated to determine the relative signal change (RE) between native and hepatobiliary phase (20min). In simple and multiple linear regression analyses, the influence of liver fibrosis/cirrhosis (Ishak score) and the histopathological degree of hepatitis (Modified Hepatic Activity Index, mHAI) on RE were evaluated. Results RE decreased significantly with increasing liver fibrosis/cirrhosis (p < 0.001) and inflammation (mHAI, p = 0.004). In particular, a correlation between RE and periportal or periseptal boundary zone hepatitis (moth feeding necrosis, mHAI A, p = 0.001) and portal inflammation (mHAI D, p < 0.001) was observed. In multiple linear regression analysis, both the degree of inflammation and the degree of fibrosis were significant predictors for RE (p < 0.01). Conclusion The results of this study suggest that the MR-based hepatic enhancement index RE is not only influenced by the degree of fibrosis, but also by the degree of inflammation.

Abstract
BACKGROUND New medicinal and surgical oncological treatment strategies not only improve overall survival rates but continually increase the importance of Health-Related Quality of Life (HRQOL). The purpose of this retrospective cross-sectional study was to analyze HRQOL of patients with oral squamous cell carcinoma after ablative surgery and to evaluate predictive factors for HRQOL outcome. METHODS The study included 88 patients with histologically confirmed oral squamous cell carcinoma of whom 42 had undergone local reconstruction (LR) and 46 microvascular reconstruction (MVR). During follow-up, all patients completed the University of Washington Quality of Life Questionnaire (UW-QOL) containing 12 targeted questions about the head and neck. Descriptive analyses were made for the tumor site, the T-stage, and adjuvant therapies. HRQOL was compared between the LR and the MVR group with parametric tests. Further analyses were impact of the tumor site, the T-status, and the time from surgery to survey on HRQOL. Statistics also included multivariate correlations and different interaction effects. RESULTS HRQOL in the LR group was 'very good' with 84.3 ± 13.7 and 'good' in the MVR group with 73.3 ± 16.5 points. The physical domains swallowing (p = 0.00), chewing (p = 0.00), speech (p = 0.01), taste (p = 0.01), and pain (p = 0.04) were significantly worse in the MVR group. An increase in the T-status had a significant negative effect on swallowing (p = 0.01), chewing (p = 0.01), speech (p = 0.03), recreation (p = 0.05), and shoulder (p = 0.01) in both groups. Regarding the tumor site and subsequent loss of HRQOL, patients with squamous cell carcinoma on the floor of the mouth had significantly worse results in the categories pain (p = 0.002), speech (p = 0.002), swallowing (p = 0.03), activity (p = 0.02), and recreation (p = 0.01) than patients with tumors in the buccal mucosa. Speech (p = 0.03) and pain (p = 0.01) had improved 1 year after surgery. CONCLUSION Patients with flap reconstruction because of oral squamous cell carcinoma showed very good overall HRQOL. Outcomes for microvascular reconstruction were good, even in the case of larger defects. The T-status is a predictor for HRQOL. Swallowing, chewing, speaking, taste, and pain were the most important issues in our cohort. Implementing HRQOL questionnaires for the assessment of quality of life could further increase the treatment quality of patients with oral cancer.

Abstract
AIM Gohel et al. aimed to compare early endovenous ablation vs. deferred endovenous ablation of superficial venous reflux with regard to time to healing of venous leg ulcers, rate of healing at 24 weeks, recurrence rate, ulcer-free time and health-related quality of life. SETTING AND DESIGN This multicentre, parallel-group (ratio 1 : 1), randomized controlled trial was conducted in a vascular surgery department setting at 20 participating centres across the U.K. STUDY EXPOSURE A total of 450 patients with venous leg ulcers were randomly assigned to receive compression therapy and undergo early endovenous ablation of superficial venous reflux within 2 weeks after randomization (early-intervention group) or to receive compression therapy alone, with consideration of endovenous ablation deferred until after the ulcer was healed or until 6 months after randomization if the ulcer was unhealed (deferred-intervention group). OUTCOMES The primary outcome was the time to ulcer healing. Secondary outcomes were the rate of ulcer healing at 24 weeks, the rate of ulcer recurrence, the length of time free from ulcers (ulcer-free time) during the first year after randomization, and patient-reported health-related quality of life. TRIAL INTERVENTIONS Endovenous laser or radiofrequency ablation, ultrasound-guided foam sclerotherapy, or nonthermal, nontumescent methods of treatment (such as cyanoacrylate glue or mechanochemical ablation) were performed either alone or in combination. The treating clinical team determined the method and strategy of endovenous treatment. RESULTS The time to ulcer healing was shorter in the early-intervention group than in the deferred-intervention group. Furthermore, more patients had healed ulcers with early intervention [hazard ratio for ulcer healing 1·38, 95% confidence interval (CI) 1·13-1·68; P = 0·001]. The median time to ulcer healing was 56 days (95% CI 49-66) in the early-intervention group and 82 days (95% CI 69-92) in the deferred-intervention group. The rate of ulcer healing at 24 weeks was 85·6% in the early-intervention group and 76·3% in the deferred-intervention group. The median ulcer-free time during the first year after trial enrolment was 306 days (interquartile range 240-328) in the early-intervention group and 278 days (interquartile range 175-324) in the deferred-intervention group (P = 0·002). The most common complications were pain and deep vein thrombosis (DVT) (early-intervention group: pain, six of 28; DVT, nine of 28; deferred-intervention group: pain, six of 24; DVT, three of 24). CONCLUSIONS Gohel et al. conclude that early endovenous ablation of superficial venous reflux results in faster healing of venous leg ulcers than deferred endovenous ablation. Patients assigned to the early-intervention group also had longer ulcer-free time during the first year after randomization.

Abstract
PURPOSE In total knee arthroplasty (TKA), intramedullary guides are often used for aligning the distal femoral cutting block. Because of the highly varying angles between the mechanical axis and the anatomical femoral axis (AMA), different valgus pre-sets have been recommended. The present study investigated the optimal valgus pre-set (measuring the AMA in long-leg radiographs or at 5°, 6°, 7° or 8° valgus) to align the cutting block perpendicularly to the mechanical axis. METHODS The AMA was preoperatively measured in weight-bearing long-leg radiographs. After alignment of the cutting block by means of an intramedullary rod, deviation of the block from the mechanical femoral axis was measured with a pinless navigation device. The true AMA (tAMA) was calculated by adding the valgus pre-set of the alignment rod to the deviation measured with the navigation device. Mean deviations between the tAMA and (a) the AMA measured by the surgeon, (b) the AMA calculated with the computer software, (c) 5°, (d) 6°, (e) 7° and (f) 8° valgus pre-sets were measured for each patient. The lowest mean differences were determined. RESULTS The 40 knees measured showed a mean tAMA of 7.2° valgus (1.7 SD) (range 4°-11.5°). The following mean differences and 95 % limits of agreement were calculated: 2.2 (-1.2, 5.5) to the tAMA for the 5° valgus pre-set, 1.2 (-2.2, 4.5) for 6°, 0.2 (-3.2, 3.5) for 7° and -0.8 (-4.2, 2.5) for 8°. AMA measurements by the surgeon and with the digital medical planning software yielded mean differences of 0.6 (-3.1, 4.3) and 0.4 (-4.1, 4.8), respectively. CONCLUSION In the present setting, the best mean distal femoral cutting block alignment perpendicular to the mechanical femoral axis could be achieved with a valgus pre-set of 7° and not by measuring the AMA. Nevertheless, we recommend conducting weight-bearing radiographs of the entire leg prior to TKA for easy detection of any anatomical varieties, old fractures, long stems of total hip arthroplasties or cement. However, surgeons must be aware that exact coronal component alignment can only be achieved by navigational devices. LEVEL OF EVIDENCE Diagnostic study, Level II.

Abstract
BACKGROUND Photodynamic therapy with daylight (DL-PDT) is efficacious in treating actinic keratosis (AK), but the efficacy of field-directed, repetitive DL-PDT for the treatment and prophylaxis of AK in photodamaged facial skin has not yet been investigated. METHODS/DESIGN In this multicenter, prospective, randomized, controlled, two-armed, observer-blinded trial, patients with a minimum of 5 mild-to-moderate AK lesions on photodamaged facial skin are randomly allocated to two treatment groups: DL-PDT with methyl aminolevulinate (MAL) and cryosurgery. In the DL-PDT group (experimental group), 5 treatments of the entire face are conducted over the course of 18 months. After preparation of the lesion and within 30 min after MAL application, patients expose themselves to daylight for 2 h. In the control group, lesion-directed cryosurgery is conducted at the first visit and, in the case of uncleared or new AK lesions, also at visits 2 to 5. The efficacy of the treatment is evaluated at visits 2 to 6 by documenting all existing and new AK lesions in the face. Cosmetic results and improvement of photoaging parameters are evaluated by means of a modified Dover scale. Primary outcome parameter is the cumulative number of AK lesions observed between visits 2 and 6. Secondary outcome parameters are complete clearance of AK, new AK lesions since the previous visit, cosmetic results independently evaluated by both patient and physician, patient-reported pain (visual analogue scale), patient and physician satisfaction scores with cosmetic results, and patient-reported quality of life (Dermatology Life Quality Index). Safety parameters are also documented (adverse events and serious adverse events). DISCUSSION This clinical trial will assess the efficacy of repetitive DL-PDT in preventing AK and investigate possible rejuvenating effects of this treatment.

Abstract
PURPOSE To assess the outcome of patients with choroidal neovascularization (CNV) secondary to punctate inner choroidopathy (PIC) receiving intravitreal anti-VEGF (vascular endothelial growth factor) injections. METHODS Sixteen eyes of 16 patients diagnosed with CNV secondary to PIC were retrospectively assessed. RESULTS Eleven women and five men with a mean age of 35 years (SD 11, range 16-56 years) received intravitreal anti-VEGF for PIC-related CNV. On average, 3.5 injections (SD 2.7, range 1-9) were given per eye. Thirteen eyes were treated with bevacizumab, two eyes with ranibizumab and one eye received both substances. The mean follow-up was 15 months (SD 11, range 6-40 months). BCVA improved in eight eyes (mean Δ +2.8 lines), remained stable in four eyes and decreased in four eyes (mean Δ -4.3 lines). CONCLUSIONS CNV development is a frequent complication of PIC. Intravitreal anti-VEGF therapy seems to be safe and effective for PIC-related CNV.

Abstract
AIM To determine different perfusion characteristics of histo-pathologically proven adenomas and carcinomas of the thyroid gland with CEUS and perfusion software. MATERIAL AND METHODS Retrospective perfusion analysis of 25 patients with carcinomas and 41 cases of adenomas of the thyroid gland (30 males, 36 females; aged 18 - 85 years, mean 56 years). All cases were histologically analyzed. Perfusion analysis was independently performed using external perfusion software (VueBox®). TTP, mTT, Peak and Rise time were calculated. RESULTS Lesions' sizes ranged from 0.2 to 10.2 cm in carcinomas (mean 2.18 cm), and from 0.6 to 5.0 cm in adenomas (mean 2.25 cm). In 20 out of 25 carcinomas that were evaluated with CEUS, a complete wash-out in the late venous phase was found. Adenomas showed wash-out at the border.Perfusion analysis in VueBox® revealed some parameters which tend to show differences between adenomas and carcinomas, however did not reach the level of significance.Median Peak in carcinomas was highest at the margins (2945 rU), and lowest in the surroundings (1110 rU). Mean Transit Time (mTT) values showed no differences between center, margin and surrounding.In adenomas healthy tissue showed higher mTT values compared to the center (24.6 vs. 20.7 sec). Median Peak was highest in the surrounding tissue and lowest in the margins (1999 vs. 1129 rU). No statistical differences could be found in the comparisons. CONCLUSION CEUS with perfusion analysis offers new possibilities for the dynamic evaluation of micro-vascularization in thyroid adenomas and carcinomas. Using VueBox® the perfusion analysis of the arterial phase provides new parameters that help determine a lesion's malignancy or benignity. However a final assessment regarding malignancy and benignity of thyroid lesions using only CEUS and perfusion analysis of the arterial phase is not yet possible.

Abstract
PURPOSE To determine the influence of preoperative aneurysmal thrombus quantity and distribution on the development of type II endoleak with aneurysm sac enlargement after endovascular aneurysm repair (EVAR). MATERIALS AND METHODS We retrospectively analyzed the pre- and postoperatively performed CT scans of 118 patients who had follow-up imaging for at least 1 year after EVAR available. We assessed preoperative thrombus perimeter (T Peri), diameter (T Dia), cross-sectional area (T CSA), and volume (T Vol). The preoperative thrombus distribution was classified into no thrombus, semilunar-shaped (anterior, right side, left side, posterior) thrombus, and circumferential type thrombus. The number of preoperative patent aortic side branches (ASB) was identified. Endpoint was type II endoleak with aneurysm volume (A Vol) increase of ≥5 % during follow-up. RESULTS During follow-up (2 years, range 1-9 years), 17 patients with type II endoleak had significant A Vol increase. Less preoperative T Peri, T Dia, T CSA, and T Vol were associated with A Vol increase. A circumferential thrombus distribution significantly protected against aneurysm enlargement (p = 0.028). The variables with the strongest significance for A Vol increase were preoperative T Vol/A Vol ratio (OR 0.95; p = 0.037) and number of patent ASB (OR 3.52; p < 0.001). CONCLUSION A low preoperative T Vol/A Vol ratio and a high number of patent ASB were associated with aneurysm sac enlargement after EVAR.

Abstract
PURPOSE The aim of this prospective study is to validate a vector arithmetic method for measuring acetabular cup orientation after total hip arthroplasty (THA) and to verify the clinical practice. MATERIALS AND METHODS We measured cup anteversion and inclination of 123 patients after cementless primary THA twice by two examiners on AP pelvic radiographs with a vector arithmetic method and compared with a 3D-CT based reconstruction model within the same radiographic coronal plane. RESULTS The mean difference between the radiographic and the 3D-CT measurements was - 1.4° ± 3.9° for inclination and 0.8°± 7.9° for anteversion with excellent correlation for inclination (r = 0.81, p < 0.001) and moderate correlation for anteversion (r = 0.65, p < 0.001). The intraclass correlation coefficient for measurements on radiographs ranged from 0.98 (95 %-CI: 0.98; 0.99) for the first observer to 0.94 (95 %-CI: 0.92; 0.96) for the second observer. The interrater reliability was 0.96 (95 %-CI: 0.93; 0.98) for inclination and 0.93 (95 %-CI: 0.85; 0.96) for anteversion. CONCLUSION The largest errors in measurements were associated with an extraordinary pelvic tilt. In order to get a valuable measurement for measuring cup position after THA on pelvic radiographs by this vector arithmetic method, there is a need for a correct postoperative ap view, with special regards to the pelvic tilt for the future. KEY POINTS • Measuring acetabular cup orientation on anteroposterior radiographs of the hip after THA is a helpful procedure in everyday clinical practice as a first-line imaging modality• CT remains the golden standard to accurately determine acetabular cup position.• Future measuring on radiographs for cup orientation after THA should account for integration of the pelvic tilt in order to maximize the measurement accuracy.

Abstract
BACKGROUND The surgical treatment of pleural empyema should be carried out depending on the stage of the disease and the patient's symptoms. The aim of this study was to evaluate the outcomes of surgical pleural empyema treatment. PATIENTS AND METHODS Retrospective analysis of all patients with pleural empyema treated surgically between January 2008 and December 2013. The primary endpoint of the study was inpatient lethality. Secondary endpoints included duration of inpatient stay, type of treatment (surgical/conservative), proof of pathogen and type, alteration and duration of antibiotic therapy. RESULTS Of 359 patients, 0.8 % (n = 3) had stage I empyema, 50.4 % (n = 181) had stage II and 48.7 % (n = 175) had stage III. The most frequent causes (32.4 %) included acute pneumonia (parapneumonic pleural empyema), surgery (usually thoracic) in 18.0 % of cases and previous pneumonia (postpneumonic pleural empyema) in 15.4 %. Surgery was performed in 86 % of cases (operative procedures: open thoracotomy 85 %, VATS 15 %). The average duration of inpatient stay was 20 days for stages II and III. Recovery following VATS was significantly shorter in stage II compared to thoracotomy (p = 0.022). Hospital lethality amounted to 7.0 % (25 patients). The lethality rate was 5.5 % (10/185) in stage II and 8.6 % (15/175) in stage III. Patients with confirmed pathogens had a significantly worse mortality rate across all stages (9.8 %) than patients with no confirmed pathogens (4.0 %, p = 0.034). Age, malignant underlying disease, multiple comorbidities, immunosuppression, a change in antibiotic regimens and sepsis were significant risk factors. CONCLUSION The inpatient lethality of patients with pleural empyema correlates with the stage of the condition. Positive confirmation of pathogens, sepsis, a higher age, multiple comorbidities, malignant tumour disease, immunosuppression and a change of antibiotics are negative prognostic factors.

Abstract
PURPOSE Aim of our study was to assess understanding of risks associated with intravascular application of contrast media in patients undergoing CT examination. We wanted to evaluate epidemiologic and socio-economic prognostic factors for a higher understanding of risks. Additionally, we evaluated a possible correlation between an extensive, outcome-oriented oral informed consent and better understanding of risks. MATERIALS AND METHODS 120 patients distributed in 2 study arms participated in this prospective study. In study arm I, the treating physician was not informed that his patients participated in a study whereas the physician in study arm II knew about the survey. After the informed consent we performed a standardized, semi-structured interview to enquire the 3 most frequent risks of intravascular application of contrast agents (anaphylactoid reactions, nephropathy and thyrotoxic crisis) and epidemiologic data. The understanding of the risks was evaluated using a 6 point scale. RESULTS Patients scored 3.73 points in study arm I and 4.93 points in arm II on average. The statistical difference between both study arms was highly significant (p <0.001). In a combined logistic regression analysis, only "higher education" (p = 0.001) and participation in study arm II (p =0 .001) showed a significant connection to a better understanding of risks. CONCLUSION Patients profit from an outcome-oriented and individualized informed consent. Due to the significant correlation between educational level and understanding of risks, informed consent should be adjusted to the educational status of the individual patient, e. g. by using didactic aids or individualized information sheets.

Abstract
BACKGROUND In many centers the standard anesthesiological care for deep brain stimulation (DBS) surgery in Parkinson's disease patients is an asleep-awake-asleep procedure. However, sedative drugs and anesthetics can compromise ventilation and hemodynamic stability during the operation and some patients develop a delirious mental state after the initial asleep phase. Further, these drugs interfere with the patient's alertness and cooperativeness, the quality of microelectrode recordings, and the recognition of undesired stimulation effects. In this study, we correlated the incidence of intraoperative delirium with the amount of anesthetics used intraoperatively. METHODS The anesthesiologic approach is based on continuous presence and care, avoidance of negative suggestions, use of positive suggestions, and utilization of the patient's own resources. Clinical data from the operations were analyzed retrospectively, the occurrence of intraoperative delirium was extracted from patients' charts. The last 16 patients undergoing the standard conscious sedation procedure (group I) were compared to the first 22 (group II) psychologically-guided patients. RESULTS The median amount of propofol decreased from 146 mg (group I) to 0mg (group II), remifentanyl from 0.70 mg to 0.00 mg, respectively (P<0.001 for propofol and remifentanyl). Using the new procedure, 12 of 22 patients (55%) in group II required no anesthetics. Intraoperative delirium was significantly less frequent in group II (P=0.03). CONCLUSIONS The occurrence of intraoperative delirium correlates with the amount of intraoperative sedative and anesthetic drugs. Sedation and powerful analgesia are not prerequisites for patients' comfort during awake-DBS-surgery.

Abstract
BACKGROUND Extracorporeal carbon dioxide removal (ECCO2-R) allows lung protective ventilation using lower tidal volumes (VT) in patients with acute respiratory failure. The dynamics of spontaneous ventilation under ECCO2-R has not been described previously. This retrospective multivariable analysis examines VT patterns and investigates the factors that influence VT, in particular sweep gas flow and blood flow through the artificial membrane. METHODS We assessed VT, respiratory rate (RR), minute ventilation (MV), and levels of pressure support (0-24 cm H2O), sweep gas flow (0-14 L/min) and blood flow through the membrane (0.8-1.8 L/min) in 40 patients from the moment they were allowed to breathe spontaneously. Modest hypercapnia was accepted. RESULTS Patients tolerated moderate hypercapnia well. In a generalized linear model the increase in sweep gas flow (P<0.001), a low PaCO2 (P=0.029), and an increased breathing frequency (P<0.001) were associated with lower VT. Neither blood flow through the membrane (P=0.351) nor the level of pressure support (P=0.595) influenced VT size. CONCLUSION Higher sweep gas flow is associated with low VT in patients on extracorporeal lung assist and augmented spontaneous ventilation. Such a technique can be used for prolonged lung protective ventilation even in the patient's recovery period.

Abstract
PURPOSE The purpose of this study was to identify clinical factors influencing Gd-EOB-DTPA liver uptake in patients with healthy liver parenchyma. MATERIALS AND METHODS A total of 124 patients underwent contrast-enhanced MRI with a hepatocyte-specific contrast agent at 3 T. T1-weighted volume interpolated breath-hold examination (VIBE) sequences with fat suppression were acquired before and 20 minutes after contrast injection. The relative enhancement (RE) between plain and contrast-enhanced signal intensity was calculated. Simple and multiple linear regression analyses were performed to evaluate clinical factors influencing the relative enhancement. Patients were subdivided into three groups according to their relative liver enhancement (HRE, RE ≥ 100 %; MRE, 100 % > RE > 50 %; NRE, RE ≤ 50 %) and were analyzed according to the relevant risk factors. RESULTS Simple regression analyses revealed patient age, transaminases (AST, ALT, GGT), liver, spleen and delta-liver volume (the difference between the volumetrically measured liver volume and the estimated liver volume based on body weight) as significant factors influencing relative enhancement. In the multiple analysis the transaminase AST, spleen and delta liver volume remained significant factors influencing relative enhancement. Delta liver volume showed a significant difference between all analyzed groups. CONCLUSION Liver enhancement in the hepatobiliary phase depends on a variety of factors. Body weight-adapted administration of Gd-EOB-DTPA may lead to inadequate liver enhancement after 20 minutes especially when the actual liver volume differs from the expected volume. KEY POINTS • Differences between actual and expected liver volume can cause inadequate liver enhancement after 20 min. • A liver volume-adapted dose of Gd-EOB-DTPA may help to improve liver enhancement.
