Abstract
BACKGROUND Cystic fibrosis (CF) is a complex systemic disease involving numerous organ systems. With improved treatment options and increasing life expectancy of persons with CF (PwCF), extrapulmonary manifestations are coming increasingly into the focus. From birth, almost all PwCF have radiologically detectable pathologies in the upper airways attributable to CF-associated chronic rhinosinusitis (CF-CRS). OBJECTIVE The aim of this work is to provide an up-to-date overview of CF-CRS from the otorhinolaryngology perspective and to provide the reader with background knowledge and current developments. PATHOPHYSIOLOGY The cystic fibrosis transmembrane conductance regulator (CFTR) gene defect leads to increased viscosity of sinonasal secretions and reduced mucociliary clearance, causing chronic infection and inflammation in the upper airway segment and, consequently, to CF-CRS. CLINICAL PICTURE AND DIAGNOSTICS The clinical picture of CF-CRS comprises a wide spectrum from asymptomatic to symptomatic courses. CF-CRS is diagnosed clinically and radiologically. THERAPY Sinonasal saline irrigation is recommended as a conservative treatment measure. Topical corticosteroids are also commonly used. Surgical therapy is reserved for highly symptomatic treatment-refractory patients without a sufficient response to conservative treatment including CFTR modulator (CFTRm) therapies. Depending on the CFTR mutation, CFTRm therapies are the treatment of choice. They not only improve the pulmonary and gastrointestinal manifestations in PwCF, but also have positive effects on CF-CRS. CONCLUSION The ENT specialist is part of the interdisciplinary team caring for PwCF. Depending on symptom burden and treatment responsiveness, CF-CRS should be treated conservatively and/or surgically. Modern CFTRm have a positive effect on the clinical course of CF-CRS.

Abstract
Vocal fatigue refers to the feeling of tiredness and weakness of voice due to extended utilization. This paper investigates the effectiveness of neural embeddings for the detection of vocal fatigue. We compare x-vectors, ECAPA-TDNN, and wav2vec 2.0 embeddings on a corpus of academic spoken English. Low-dimensional mappings of the data reveal that neural embeddings capture information about the change in vocal characteristics of a speaker during prolonged voice usage. We show that vocal fatigue can be reliably predicted using all three types of neural embeddings after 40 minutes of continuous speaking when temporal smoothing and normalization are applied to the extracted embeddings. We employ support vector machines for classification and achieve accuracy scores of 81% using x-vectors, 85% using ECAPA-TDNN embeddings, and 82% using wav2vec 2.0 embeddings as input features. We obtain an accuracy score of 76%, when the trained system is applied to a different speaker and recording environment without any adaptation.

Abstract
Grinding wheels are usually manufactured by powder metallurgical processes, i.e., by molding and sintering. Since this requires the production of special molds and the sintering is typically carried out in a continuous furnace, this process is time-consuming and cost-intensive. Therefore, it is only worthwhile for medium and large batches. Another influencing factor of the powder metallurgical process route is the high thermal load during the sintering process. Due to their high thermal sensitivity, superabrasives such as diamond or cubic boron nitride are very difficult to process in this way. In this study, a novel and innovative approach is presented, in which superabrasive grinding wheels are manufactured by thermal spraying. For this purpose, flat samples as well as grinding wheel bodies were coated by low-pressure (LP) cold gas spraying with a blend of a commercial Cu-Al2O3 cold gas spraying powder and nickel-coated diamonds. The coatings were examined metallographically in terms of their composition. A well-embedded superabrasive content of 12 % was achieved. After the spraying process, the grinding wheels were conditioned and tested for the grinding application of cemented carbides and the topographies of both the grinding wheel and the cemented carbide were evaluated. Surface qualities of the ground surface that are comparable to those of other finishing processes were reached. This novel process route offers great flexibility in the combination of binder and hard material as well as a cost-effective single-part and small-batch production.

Abstract
Abstract
Objectives
We investigate how individual trajectories of health status and labor force participation among older workers in Switzerland are interrelated and how this relationship varies by occupation.
Methods
We use data from the Swiss Household Panel (SHP) to analyze the long-term trajectories of older workers, measured in terms of working hours and general health status. The sample includes more than 7,000 workers aged 50 to 65(men)/64(women). We run a bivariate response multilevel model for growth that allows examining between- and within-individual changes over time.
Results
All occupational groups become more heterogeneous in terms of health status with increasing age. At the same time, working hours decrease in all occupational groups with increasing age. A look at the individual level indicates that the working hours of manual workers seem to be more dependent on their health status compared to those of non-manual workers and that this dependence increases over time. This result confirms our hypothesis that the labor market participation of manual workers is more sensitive to their health status.
Conclusions
Our findings contribute to the debate about the importance of older workers' health in the context of working life extension.
Key messages
All occupational groups become more heterogenous in terms of health status with increasing age, however working hours of manual workers seem to be more dependent on their health status. Manual workers experience a stronger effect of health on working hours and that this effect increases over time, therefore prevention of ill health may be particularly beneficial in manual workers.

Abstract
Nowadays, social projects are usually oriented in such a way that after a given period of time, they can either support themselves independently or even allow a pecuniary reimbursement. In the latter case, experts speak of a profit-oriented reimbursement. On the other hand, there is so-called social reimbursement, which in contrast to the abovementioned form is not profit oriented, but, for example, considers its task fulfilled by the fact of successful knowledge transfer. The Spanish-German Society for ENT Medicine and Head and Neck Surgery (SDGHNO) launched the Latin America project in 2001 under the patronage of the then President Prof. Dr. Wolfgang Draf (Fulda). The goal of the SDGHNO was and is to create a professional as well as cultural platform for Spanish- and German-speaking ENT doctors. This platform can and should be used for professional purposes, e.g., for knowledge transfer. Since the beginning of its existence, the Latin America project has thus brought numerous scientific events into being and created specific contacts which have lasted until today or have even been continued and further developed. Particularly successful examples are Chile, Colombia, and Peru. This is a vivid example of social reimbursement, because the participating German-speaking members/speakers carried out their tasks on an entirely voluntary basis. Thus, the SDGHNO did not bear any travel, catering, or accommodation costs. The activities of the SDGHNO within the framework of the Latin America project are explained.

Abstract
The evaluation of results after middle ear reconstruction has been mainly based on functional parameters. In clinical practice as well as in otological research, the pure tone audiogram represents the gold standard in the assessment of the postoperative outcome. In order to assess the patient's subjective outcome, outcome analyzes focus increasingly on the health-related quality of life (HRQOL). However, the evaluation of HRQOL requires reliable and validated measuring instruments. A modest number of validated questionnaires for determination of the disease-specific HRQOL in patients with chronic otitis media and/or conductive hearing loss are currently available. Three of seven available questionnaires were developed and validated in the German-speaking countries, the Zurich Chronic Middle Ear Inventory 21 (ZCMEI-21), the Chronic Otitis Media Outcome Test 15 (COMOT-15) and the Stapesplasty Outcome Test 25 (SPOT-25). In this review, all seven available disease-specific measuring instruments as well as the generic questionnaires, which were used in previous clinical trials, are explained and current findings of quality-of-life research in patients with chronic otitis media and/or conductive hearing loss are presented.

Abstract
BACKGROUND Otosclerosis affects health-related quality of life (HRQOL). Until now, measurements have only been performed using audiometric data or non-validated quality of life questionnaires. OBJECTIVE The objective of this study was to develop the first validated disease-specific HRQOL measuring instrument to determine HRQOL in otosclerosis. MATERIALS AND METHODS After sequential analysis and item reduction of the initial Stapesplasty Outcome Test 47 (SPOT-47), the SPOT-25 was validated prospectively on 52 otosclerosis patients undergoing stapes surgery. In addition to the overall score, four subscores were defined (hearing function, tinnitus, social restrictions, mental condition). RESULTS The SPOT-25 showed a high internal consistency (Cronbach's α > 0.7), allowed discrimination between otosclerosis patients and healthy subjects, and demonstrated acceptable test-retest reliability (r = 0.85). After stapes surgery, the HRQOL improved significantly. The responsiveness was high. CONCLUSION The SPOT-25 is the first validated disease-specific instrument for HRQOL measurement in otosclerosis patients. It should be used routinely for quality control.

Abstract
BACKGROUND Postoperative swallowing pain is one of the most unpleasant after-effects of tonsillectomy. During recent years, the demand for alternatives to drug-based pain therapy has continued to grow, although the topic has received little research attention until now. MATERIALS AND METHODS A total of 46 patients were randomized into verum acupuncture, control acupuncture, and drug-based treatment groups. All patients received nonsteroidal antirheumatic drugs (NSAIDs). One hour after drug intake, the verum group also received acupuncture according to classical acupuncture rules (S34, S44 and PC5). The control group had acupuncture needles placed at nonspecific acupuncture points in the midaxillary line. Acupuncture was performed by a blinded acupuncturist, who had learnt exclusively these techniques in the run up to the study. Patients were asked to evaluate their pain before, and at intervals of 20 min, 1 h, 2 h, and 3 h after drug intake/acupuncture treatment using a visual analog scale (VAS). RESULTS The analgesic effect of acupuncture was significant up to 3 hours in the verum group (p < 0.05). The analgesic effect in the control acupuncture group was significant for up to 1 h after acupuncture (p < 0.05). With reference to the time point before acupuncture, the differences between both acupuncture groups and the drug group were significant (p < 0.01) over the whole time. CONCLUSION Acupuncture is an effective complement to NSAIDs in the treatment of posttonsillectomy pain. Particularly patients with allergies, drug intolerance, or reduced response to the commonly administered drugs may benefit from acupuncture.

Abstract
Many countries are raising the age of pension eligibility because of increases in life expectancy. Given the social gradient in life expectancy and health, it is important to understand the potential late-life health effects of prolonging working life and whether any effects differ by socioeconomic position. We examined the effect of prolonging working life beyond age 65 on mortality and a series of indicators of late-life physical health (the ability to climb stairs without difficulty, self-rated health, ADL limitations, and musculoskeletal pain) in a representative sample of the Swedish population. In addition to average effects, we also examined heterogeneous effects, for instance by occupational social class. To do this, we use propensity score matching, a method suitable for addressing causality in observational data. The data came from two linked Swedish longitudinal surveys based on nationally representative samples with repeated follow-ups; The Swedish Level of Living Survey and the Swedish Panel Study of Living conditions of the Oldest Old, and from national income and mortality registries. The analytical sample for the mortality outcome included 1852 people, and for late-life physical health outcomes 1461 people. We found no significant average treatment effect on the treated (ATT) of working to age 66 or above on the outcomes, measured an average of 12 years after retirement: mortality (ATT -0.039), the ability to climb stairs (ATT -0.023), self-rated health (ATT -0.009), ADL limitations (ATT -0.023), or musculoskeletal pain (ATT -0.009) in late life. Analyses of whether the results varied by occupational social class or the propensity to prolong working life were inconclusive but suggest a positive effect of prolonging working life on health outcomes. Accordingly, more detailed knowledge about the precise mechanisms underlying these results are needed. In conclusion, working to age 66 or above did not have effect on mortality or late-life physical health.

Abstract
BACKGROUND Nose reconstruction following resection of nasal carcinomas is controversial. The objective of this study is to investigate the effect of surgical reconstruction versus prosthetic rehabilitation on patient quality of life (QOL). DESIGN This was a monocentric prospective study of patients diagnosed with nasal carcinoma from 2003 to 2013. QOL was evaluated using two organ-specific questionnaires (Rhinoplasty Outcome Evaluation [ROE] and the Functional Rhinoplasty Outcome Inventory-17 [FROI-17]) and a generic questionnaire, the Short-Form 36 Health Survey (SF-36). MATERIAL AND METHODS Sixty-four patients were included. Patients completed the ROE, FROI-17, and SF-36 questionnaires after nasal reconstruction. Questionnaires were completed by 62.8% of the 51 alive patients. RESULTS Recurrence-free survival (RFS) was 89.9%, disease-specific survival was 94.5%, and overall survival was 75.5% after five years according to the Kaplan-Meier method. Considering initial tumor stage, early stage patients had a significantly higher self-confidence score in FROI-17 subgroup analysis. In contrast, advanced stage patients showed a significantly higher score for social functioning in SF-36. Prosthetically fitted patients scored highly on the ROE questionnaire showing a high degree of aesthetic satisfaction. Surgically reconstructed patients showed a high degree of self-confidence on the FROI-17 questionnaire. However, the organ-specific ROE and FROI-17 scores were not significantly different between patients who received surgical reconstruction and prosthetic rehabilitation after oncological resection. When comparing the rehabilitation method as a function of tumor stage, there was significantly better score for physical functioning in early stage surgically reconstructed patients in the SF-36, but no significant differences in organ-specific QOL. CONCLUSION Surgical reconstruction and prosthetic rehabilitation after nasal cancer resection have the same effect on organ- and non-organ-specific QOL.

Abstract
Cystic Fibrosis (CF) is the most common autosomal-recessive genetic disease affecting approximately 8000 people in Germany. The disease is caused by mutations in the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene leading to dysfunction of CFTR, a transmembrane chloride channel. This defect causes insufficient hydration of the epithelial lining fluid which leads to chronic inflammation of the airways. Recurrent infections of the airways as well as pulmonary exacerbations aggravate chronic inflammation, lead to pulmonary fibrosis and tissue destruction up to global respiratory insufficiency, which is responsible for the mortality in over 90 % of patients. The main aim of pulmonary treatment in CF is to reduce pulmonary inflammation and chronic infection. Pseudomonas aeruginosa (Pa) is the most relevant pathogen in the course of CF lung disease. Colonization and chronic infection are leading to additional loss of pulmonary function. There are many possibilities to treat Pa-infection. This is a S3-clinical guideline which implements a definition for chronic Pa-infection and demonstrates evidence-based diagnostic methods and medical treatment for Pa-infection in order to give guidance for individual treatment options.

Abstract
BACKGROUND Quality of life measurements are gaining in importance. The present study was conducted with the aim to compare patient satisfaction after septorhinoplasty according to their preoperative nasal deformity. METHODS The patients completed two disease-specific questionnaires before their surgery: the Functional Rhinoplasty Outcome Inventory (FROI-17), the Rhinoplasty Outcome Evaluation (ROE) and as a general instrument, the Short Form 36 Health Survey (SF-36). The second measurement was taken during an outpatient examination 12 months after their primary septorhinoplasty. Patients were grouped in nasal axis deviation (NAD), nasal hump deformity (NHD) and NAD plus NHD. Additionally the patients with preoperative NAD and NAD+NHD were combined as deviated nose and compared to the non-deviation group. RESULTS One hundred and two patients (51 male and 51 female) underwent primary septorhinoplasty. The ROE- and the FROI-17 overall score including all three subgroups showed significant postoperative improvements. Regarding the SF-36, the postoperative score improved significantly only in two scales (role-functioning physical and mental health). Looking at the the different QoL questionnaires, there were significant postoperative differences in regards to deviated versus non-deviated nose in the FROI-17 overall- and FROI-17 subscores (nasal and general symptoms) and in three scales of the SF-36 (vitality, social functioning, role-functioning emotional), showing a greater postoperative satisfaction in the deviated-nose patient. CONCLUSION Patients with and without nasal deviation showed improved QoL after their surgery, as measured with the ROE, the FROI-17 and the SF-36. The patients with a nasal deviation showed a significantly better outcome, as measured with the FROI-17, in comparison with the non-deviated group.

Abstract
BACKGROUND Vestibular schwannoma (VS) is a disease which might affect health-related quality of life (HR-QOL) in a negative manner. For many years, only generic quality of life instruments such as SF-36 were available to measure HR-QOL. However, some years ago, the Penn Acoustic Neuroma Quality Of Life (PANQOL) tool, a disease-specific instrument, was developed and validated. It is expected that the application of this instrument will be able to better assess relevant aspects of the HR-QOL of VS patients in the future. A validated German version of the instrument does not exist yet. The disease-specific symptoms most frequently named by patients are headache and dizziness. RESULTS AND DISCUSSION The available literature shows that the therapeutic approaches affect HR-QOL differently. In particular, radiation therapy of small and medium-sized tumors has no pronounced negative effects on HR-QOL. However, restrictions after surgery become similar to those after radiotherapy over the course of several years. For large VS with a diameter >3 cm, no guiding data on this aspect are currently available. To clarify the outstanding issues, future prospective studies with long-term follow-up of 10 years and more are desirable.

Abstract
In cystic fibrosis (CF) mucociliary clearance of the entire respiratory system is impaired. This allows pathogens, such as Pseudomonas aeruginosa to persist and proliferate, which by progressive pulmonary destruction causes 90 % of premature deaths due to this inherited disease. The dramatic improvement in life expectation of patients due to intensive therapy has resulted in the inevitable but variably expressed sinonasal involvement coming into the clinical and scientific focus. Thereby, almost all CF patients reveal sinonasal pathology and many suffer from chronic rhinosinusitis. Recently, the sinonasal niche has been recognized as a site of initial and persistent colonization by pathogens. This article presents the pathophysiological background of this multiorgan disease as well as general diagnostic and therapeutic standards. The focus of this article is on sinonasal involvement and conservative and surgical options for treatment. Prevention of pathogen acquisition is an essential issue in the otorhinolaryngological treatment of CF patients.

Abstract
Butyric acid is a valuable building-block for the production of chemicals and materials and nowadays it is produced exclusively from petroleum. The aim of this study was to develop a suitable and robust strain of Clostridium tyrobutyricum that produces butyric acid at a high yield and selectivity from lignocellulosic biomasses. Pretreated (by wet explosion) and enzymatically hydrolysed wheat straw (PHWS), rich in C6 and C5 sugars (71.6 and 55.4 g l−1 of glucose and xylose respectively), was used as substrate. After one year of serial selections, an adapted strain of C. tyrobutyricum was developed. The adapted strain was able to grow in 80% (v v−1) PHWS without addition of yeast extract compared with an initial tolerance to less than 10% PHWS and was able to ferment both glucose and xylose. It is noticeable that the adapted C. tyrobutyricum strain was characterized by a high yield and selectivity to butyric acid. Specifically, the butyric acid yield at 60–80% PHWS lie between 0.37 and 0.46 g g−1 of sugar, while the selectivity for butyric acid was as high as 0.9–1.0 g g−1 of acid. Moreover, the strain exhibited a robust response in regards to growth and product profile at pH 6 and 7.

Abstract
Fanconi anemia (FA) is a genomic instability syndrome associated with bone marrow failure, myelodysplastic syndrome (MDS), and/or acute myeloid leukemia (AML) requiring hematopoietic stem cell transplantation (HSCT) to restore normal hematopoiesis. Although low-intensity fludarabine-based preparative regimens without radiation confer excellent outcomes in FA HSCTs with HLA-matched sibling donors, outcomes for FA patients with alternative donors are less encouraging, albeit improving. We present our experience with 17 FA patients who completed mismatched related or unrelated donor HSCT using a non-radiation fludarabine-based preparative regimen at Charité University Medicine Berlin. All patients engrafted; however, one patient had unstable chimerism in the setting of multi-viral infections that necessitated a stem cell boost to revert to full donor chimerism. Forty-seven percent of patients developed grade I acute graft-verus-host disease (aGVHD). No grade II-IV aGVHD or chronic graft-versus-host disease of any severity occurred. At a median follow-up of 30 months, 88 % of patients are alive with normal hematopoiesis. Two patients died of infections 4 months post-transplantation. These results demonstrate that short-term outcomes for FA patients with mismatched and unrelated donor HSCTs can be excellent using chemotherapy only conditioning. Viral reactivation, however, was a major treatment-related complication.

Abstract
BACKGROUND Until now, no validated instrument to measure disease-specific, health-related quality of life (HR-QOL) in adults with chronic tonsillitis (CTO) exists. MATERIAL AND METHODS After an item reduction of the alpha-version of the Tonsillectomy Outcome Inventory (TOI), the TOI-14 resulted. In addition to the total score, it includes the subscales throat problems, overall health, resources, and social-psychological restrictions. In phase 2, the TOI-14 was prospectively validated on 108 adults with CTO, who had undergone a tonsillectomy. RESULTS The TOI-14 had, on average, good reliability. It included all important aspects of the HR-QOL. Patients with CTO can be distinguished with high sensitivity from healthy subjects. All scores showed moderate to good correlation with the subjective limitation in quality of life. The sensitivity of the questionnaire demonstrated major effects postoperatively. CONCLUSION The TOI-14 constitutes the first worldwide-validated, disease-specific instrument to measure HR-QOL in adults with CTO. Due to its ease of use, it can be utilized both in the outcome research and in clinical routine.

Abstract
Facial pain and headaches are heterogeneous, therefore, a differential diagnosis, interdisciplinary survey and mapping of the pain symptoms are essential for determination of treatment concepts. This requires an otorhinolaryngology (ENT) adapted zoning of the various pains in the head and neck in line with the classification of the International Headache Society (IHS). In this review, idiopathic, symptomatic and neuralgic facial pain and headaches will be differentiated and classified according to their location from the ENT medical point of view. This provides otolaryngologists with a simplified, targeted diagnosis and subsequent indication for therapy.

Abstract
INTRODUCTION The audiometric results after reconstructive tympanic surgery on 504 patients carried out between October 2005 and October 2007, including 190 cases of tympanoplasty type I and 314 cases of tympanoplasty type III according to Wullstein, were retrospectively analyzed at the Department of Otolaryngology, Ruprecht-Karls-University in Heidelberg. PATIENTS AND METHODS To investigate the influence of the frequencies used to compare the outcome, the pure tone average air-bone gaps (PTA-ABG) of the preoperative and postoperative audiograms of tympanoplasties type I and III were analyzed. The frequencies covered the ranges of 0.5 kHz, 1 kHz, 2 kHz, 4 kHz and 6 kHz. In each case the 3-frequency, 4-frequency and 5-frequency analyses were calculated for the different surgical groups. RESULTS The 3-frequency analysis (0.5 kHz, 1 kHz and 2 kHz) of the type 1tympanoplasties were 18.8 ± 11.8 dB preoperative and 12.3 ± 11.8 dB postoperative. In 58.9% of cases the PTA-ABG ≤ 10 dB and in 86.7% it was ≤ 20 dB. The 3-frequency analysis showed that the tympanoplasties type III had a PTA-ABG of 30.6 ± 15.3 dB preoperatively and 21.8 ± 15.1 dB postoperatively. In 30.4% of cases the PTA-ABG was ≤ 10 dB and ≤ 20 dB for 56%. DISCUSSION The detailed itemization of frequencies in this study and the consequent opportunity to modify the frequency range, allowed the impact of this selection on the PTA-ABG to be illustrated and various comparisons with other studies could be carried out. In this article, the exclusion criteria were dealt with liberally and risk patients were also included and data from patients who displayed prognostic risks regarding the successful surgery in terms of the audiometric reports were integrated. These prognostic risks were due to the poor aeration of the tympanum and recent (sometimes diverse), pre-surgery as well as chronic inflammatory processes. This study has proved that all surgery collectives showed significant improvements of the PTA-ABG. Therefore, all surgery collectives (measured against the audiometric evaluation) benefited from the surgery.

Abstract
Human epidermal growth factor receptor 2 (HER2) testing is an essential part of pathological assessment in breast cancer patients, as HER2 provides not only prognostic but also predictive information on response to targeted therapy. So far, HER2 test accuracy of immunohistochemistry/in situ-hybridization techniques is still under debate, and more reliable and robust technologies are needed. To address this issue and to evaluate the predictive value of HER2 on chemotherapy, we investigated a cohort of 278 patients from the GeparTrio trial, a prospective neoadjuvant anthracycline/taxane-based multicenter study. In the GeparTrio trial, patients were not treated with any anti-HER2 therapy, as this was not standard therapy at this time. The HER2 status was analyzed by three different approaches: local and central evaluation using immunohistochemistry combined with in situ-hybridization as well as evaluation of HER2 mRNA expression using kinetic RT-PCR from formalin-fixed, paraffin-embedded (FFPE) tissue samples using a predefined cutoff. HER2 overexpression/amplification was observed in 37.3% (91/244) and 17.9% (41/229) of the informative samples in the local and central evaluations, respectively. Positive HER2 mRNA levels were found in 19.8% (55/278). We observed a highly significant correlation between central HER2 expression and HER2 status measured by kinetic RT-PCR (r = 0.856, P < 0.0001) and an overall agreement of 95.6% (κ statistic, 0.862, CI 0.77-0.94). Further, central HER2 as well as HER2 mRNA expression were predictors for a pathological complete response after neoadjuvant anthracycline/taxane-based primary chemotherapy in a univariate binary logistic regression analysis (OR 3.29, P = 0.002; OR 2.65, P = 0.004). The predictive value could be confirmed for the central HER2 status by multivariate analysis (OR 3.04, P = 0.027). The locally assessed HER2 status was not predictive of response to chemotherapy. Our results suggest that standardized methods are preferable for evaluation of HER2 status. The kinetic RT-PCR from FFPE tissue might be an additional approach for assessment of this important prognostic and predictive parameter but has to be confirmed by other studies.

Abstract
Septoplasty is one of the most frequently performed otorhinolaryngological procedures which might be very challenging for the surgeon. An accurate preoperative diagnosis of pathologies of the septum in the context of the nasal cavity is essential for the success of surgery. Intraoperative visualization through microscope or endoscope is very helpful for the surgeon and for the training of the residents. The modern technique of septoplasty with the phases of approach, mobilization, resection/repositioning and reconstruction/fixation is presented. Furthermore, the extracorporeal septoplasty in extreme deviations of the septum and alternative techniques for use in cases with limited pathologies as well as aspects of septoplasty in children are discussed. As particularly pathologies of the caudal septum are responsible for failures of septal surgery, some special problems of this region such as the vertical fracture of the caudal septum, the lack of caudal septum or anterior convexities of the cartilaginous septum are argued. Finally, advices for the management of intra-and postoperative complications are given.

Abstract
Subjective assessment of quality of life (QOL) as an important aspect of outcomes research has received increasing importance during the past decades. QOL is measured with standardized questionnaires which had been tested with regard to reliability, validity, and sensitivity. Surgical procedures of the nasal septum (septoplasty) and the external nose (rhinoplasty) are frequently performed. Since many years subjectively assessed results of these operations have been reported in the literature. Nevertheless, validated QOL instruments were applied only for one decade. Beforehand, measurements were performed using retrospective assessment of contentment or visual analogue scales. Prospective application of validated disease-specific and general measuring instruments has to be demanded for future studies.Most of the septoplasty patients as well as most of the rhinoplasty patients evaluate the operation being successful. Nevertheless, a relevant number of patients is not satisfied with the result of surgery. In this context, QOL instruments have the potential to identify further factors influencing the outcome. Especially in rhinoplasty patients, special attention has to be drawn on potential psychosocial effects of the operation.

Abstract
INTRODUCTION Quality of life measurements with the Sino-Nasal Outcome Test-20 German Adapted Version (SNOT-20 GAV) in chronic rhinosinusitis (CRS) patients require normative values measured in a comparison group taken from the normal population. These will make it possible to reach conclusions on correlations between scores and severity of symptoms and also on how close such patients' scores can get to those scores recorded in healthy subjects after surgical treatment. PATIENTS AND METHODS We collected SNOT-20 GAV data and data on the presence of CRS from 778 subjects via a web-based survey of employees of the University Hospital in Heidelberg. For comparison we used data collected before surgery and at 3 months and 1 year after surgery from 163 CRS patients who had undergone endonasal sinus surgery (ESS). RESULTS Gender and age had no clinically significant impact on the SNOT-20 GAV scores. We defined an assessment scale with four classes of symptom intensity. Surgically treated patients with CRS showed a persisting small disadvantage in the scales of the SNOT-20 GAV compared with the reference subgroup without CRS. When surgically treated CRS patients were compared with the entire reference group these disadvantages were only obvious in the Primary Nasal Symptoms (PNS) scale and not in the other scales measuring quality of life. CONCLUSION Patients with CRS benefit from ESS and subsequently reach scores similar to those recorded in the reference group. The newly developed four-level assessment scale is easy to use and gives the attending physician additional information about the severity of the patients' illness and its effects on their subjective wellbeing.

Abstract
BACKGROUND Against the background of constantly intensifying economic pressure in the healthcare sector, in the future confirmation of subjective and economic benefit of different forms of therapy will be the criterion applied by the health insurance companies to decide whether to reimburse the costs they involve. The aim of this study was to provide confirmation that patients with chronic rhinosinusitis (CRS) do benefit from functional endonasal sinus surgery (FESS). PATIENTS AND METHODS One year after undergoing FESS for the treatment of CRS, 82 patients completed various questionnaires. The Glasgow Benefit Inventory (GBI) was used, as it is a validated instrument for the assessment of benefit. In addition, the patients were asked to complete questionnaires relating to pre- and postoperative use of resources (use of antibiotics, visits to their doctors and time unfit for work) and also to give an overall rating of their satisfaction with the outcome, the difference in their symptoms after FESS and the likelihood that they would recommend this treatment to friends or relatives. RESULTS Three out of four GBI scales [total score (+22.6), general benefit (+26.8), physical functioning (+23.7)] indicated that patients experienced significant benefit. The frequency of visiting their doctors, their intake of antibiotics and the amount of time off work were all significantly reduced. The vast majority of patients were satisfied with the overall result and the level of symptom relief achieved and would recommend FESS to friends and relatives. CONCLUSION The vast majority of these patients with CRS experienced FESS as highly beneficial. A significant reduction of resource usage was reported after the operation.

Abstract
Myelodysplastic syndromes (MDS) are a heterogenous group of acquired hematopoietic stem cell disorders. Refractory cytopenia (RC) is the most common subtype of childhood MDS and hematopoietic stem cell transplantation (HSCT) is the only curative treatment. HSCT following a myeloablative preparative regimen is associated with a low probability of relapse and considerable transplant-related mortality. In the present European Working Groups of MDS pilot study, we investigated whether a reduced intensity conditioning regimen (RIC) is able to offer reduced toxicity without increased rates of graft failure or relapse. Nineteen children with RC were transplanted from an unrelated donor following RIC consisting of fludarabine, thiotepa and anti-thymocyte globulin. Three patients experienced graft failure. Neutrophil and platelet engraftment occurred at a median time of 23 and 30 days, respectively. Cumulative incidence of grade II-IV and grade III and IV acute graft-versus-host disease (GVHD) was 0.48 and 0.13, respectively; three patients developed extensive chronic GVHD. Although infections were the predominant complications, only one patient with extensive chronic GVHD died from infectious complications. Overall and event-free survival at 3 years were 0.84 and 0.74, respectively. In conclusion, our results were comparable to those of patients treated with myeloablative HSCT. Long-term follow-up is needed to demonstrate the expected reduction in long-term sequelae.
