Quality of Life and Screening on Body Dysmorphic Disorder, Depression, Anxiety in Septorhinoplasty

OBJECTIVES

Septorhinoplasty (SRPL) can improve quality of life (QoL) in functional and aesthetical aspects of the nose. A key factor compromising postoperative satisfaction is symptoms of body dysmorphic disorder (BDD), defined by excessive concerns and distress over slight or imagined physical defects. Although a high prevalence of BDD in SRPL patients is evident, the effect of positive screening on BDD and other psychiatric disorders is understudied. It was hypothesized that patients screening positive for BDD, depression or anxiety do not show increased postoperative QoL.

METHODS

A multicenter, prospective study including 259 patients. For psychiatric evaluation, the BDD concern questionnaire-aesthetic version and the Hospital Anxiety and Depression Scale were used; for disease-specific QoL the Rhinoplasty Outcomes Evaluation (ROE) and the Functional Rhinoplasty Outcome Inventory (FROI-17).

RESULTS

In preoperative evaluation, 32.5% had a positive screening for BDD, 42.2% for increased anxiety, and 32.9% for depression. Mean QoL improved in the whole cohort (FROI total score: 54.4 ± 21.8 to 32.8 ± 23.7 and ROE: 32.3 ± 15.6 to 69.8 ± 23.1, both p < 0.001). Patients screening positive for BDD, depression or anxiety did show an increased postoperative QoL, but to a significantly lower degree and with lower pre- and postoperative QoL levels.

CONCLUSIONS

SRPL patients show a high prevalence of BDD symptoms, elevated anxiety, and depression. These subgroups show lower QoL levels and an impaired QoL increase after surgery. Rhinoplasty surgeons must be aware of the disorders and their symptoms, discuss potential concerns with the patients, and potentially refer them to a specialist.

[Pediatric chronic rhinosinusitis]

Pediatric chronic rhinosinusitis (PCRS) differs from adult chronic rhinosinusitis (CRS) in several aspects. The confrontation with the environment takes place in the growing sinus system, and the immune system is also developing. The inflammatory mechanisms differ to some extent from those of adult CRS patients. The adenoid vegetations play an important role, particularly during the first 6 years of life. Other pathogenetic aspects are important (e.g., asthma, gastroesophageal reflux disease, immunodeficiency). Genetically determined systemic diseases such as cystic fibrosis cause specific challenges in diagnostics and treatment already in childhood. Consistent conservative therapy is often successful, but surgical procedures that have been proven to be effective and associated with few complications are also increasingly used.

[Choanal atresia repair in Germany : Resection of dorsal septal parts and stents in focus]

BACKGROUND

Various surgical techniques using transpalatinal, transseptal, and transnasal approaches for surgical repair of choanal atresia have been developed over the past 200 years. Endoscopic endonasal surgery with resection of dorsal septal parts and without the use of stents is the current scientific trend, as high success rates with low complication rates can be achieved. This study examined whether this technique has actually become standard in Germany, and also investigates the role played by stents.

METHODS

A total of 52 ear, nose, and throat (ENT) hospitals in Germany, including all 39 university ENT hospitals and 13 non-university maximum-care ENT hospitals, were asked which surgical technique they use for choanal atresia repair and whether stents are used.

RESULTS

For dorsal septal resection, 39 of 44 responding hospitals (89%) indicated that they resect dorsal septal parts, 85% of the university hospitals and 100% of the non-university hospitals. For use of stents, 20 of 48 responding hospitals (42%) reported not using stents, whereas 39% of the university hospitals and 50% of the non-university hospitals do use them.

CONCLUSION

Endoscopic endonasal choanal atresia repair with resection of dorsal septal parts is, in most instances, used as the standard technique in large ENT hospitals in Germany. Routine use of stents is still widespread. The future aim should be to reduce the use of stents in the treatment of choanal atresia and to use this method only in difficult, individual cases.

Magnetic Resonance Imaging of Pulmonary and Paranasal Sinus Abnormalities in Children with Primary Ciliary Dyskinesia Compared to Children with Cystic Fibrosis

Rationale: Primary ciliary dyskinesia (PCD) and cystic fibrosis (CF) are characterized by inherited impaired mucociliary clearance leading to chronic progressive lung disease as well as chronic rhinosinusitis (CRS). The diseases share morphological and functional commonalities on magnetic resonance imaging (MRI) of the lungs and paranasal sinuses, but comparative MRI studies are lacking. Objectives: To determine whether PCD shows different associations of pulmonary and paranasal sinus abnormalities on MRI and lung function test results in children (infants to adolescents) compared with children with CF. Methods: Eighteen children with PCD (median age, 9.5 [IQR, 3.4-12.7] yr; range, 0-18 yr) and 36 age-matched CF transmembrane conductance regulator modulator-naive children with CF (median age, 9.4 [3.4-13.2] yr; range, 0-18 yr) underwent same-session chest and paranasal sinus MRI as well as spirometry (to determine forced expiratory volume in 1 s percent predicted) and multiple-breath washout (to determine lung clearance index z-score). Pulmonary and paranasal sinus abnormalities were assessed using previously validated chest MRI and CRS-MRI scoring systems. Results: Mean chest MRI global score was similar in children with PCD and CF (15.0 [13.5-20.8] vs. 15.0 [9.0-15.0]; P = 0.601). Consolidations were more prevalent and severe in children with PCD (56% vs. 25% and 1.0 [0.0-2.8] vs. 0.0 [0.0-0.3], respectively; P < 0.05). The chest MRI global score correlated moderately with forced expiratory volume in 1 second percent predicted in children with PCD and children with CF (r = -0.523 and -0.687; P < 0.01) and with lung clearance index in children with CF (r = 0.650; P < 0.001) but not in PCD (r = 0.353; P = 0.196). CRS-MRI sum score and mucopyocele subscore were lower in children with PCD than in children with CF (27.5 [26.3-32.0] vs. 37.0 [37.8-40.0] and 2.0 [0.0-2.0] vs. 7.5 [4.8-9.0], respectively; P < 0.01). CRS-MRI sum score did not correlate with chest MRI score in PCD (r = 0.075-0.157; P = 0.557-0.788) but correlated moderately with MRI morphology score in CF (r = 0.437; P < 0.01). Conclusions: MRI detects differences in lung and paranasal sinus abnormalities between children with PCD and those with CF. Lung disease does not correlate with CRS in PCD but correlates in CF.

[Chronic rhinosinusitis in people with cystic fibrosis-an up-to-date review from the perspective of otorhinolaryngology]

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.

[CF Lung Disease - a German S3 Guideline: Pseudomonas aeruginosa]

Cystic Fibrosis (CF) is the most common autosomal recessive genetic multisystemic disease. In Germany, it affects at least 8000 people. 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 airway epithelial lining fluid which leads to reduction of the mucociliary clearance.Even if highly effective, CFTR modulator therapy has been available for some years and people with CF are getting much older than before, recurrent and chronic infections of the airways as well as pulmonary exacerbations still occur. In adult CF life, Pseudomonas aeruginosa (PA) is the most relevant pathogen in colonisation and chronic infection of the lung, leading to further loss of lung 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 in order to give guidance for individual treatment options.

Impact of Psychiatric Symptoms on Nasal Perception in Septorhinoplasty Patients

Psychological assessment plays a crucial role in the preoperative phase of septorhinoplasty (SRPL), exerting potential influence on both pre- and postoperative aspects of quality of life (QoL). In this prospective study, SRPL patients were systematically screened using two validated questionnaires for body dysmorphic disorder (BDD) and one each for anxiety, depression, and somatic symptom disorder (SSD). Nasal perception was evaluated utilizing two disease-specific, self-report instruments: The Rhinoplasty Outcomes Evaluation (ROE) and the Functional Rhinoplasty Outcome Inventory-17 (FROI-17). A total of 95 patients were enrolled. Positive screening rates were 40.4 and 28.3% for BDD, 37.3% for elevated anxiety, 16.4% for depression, and 22.4% for SSD. Mean scores on the ROE and FROI indicated lower QoL in all positive screening groups. Statistically significant differences were observed for anxiety (FROI total score: 47.1 ± 14.6 to 37.8 ± 16.2; p = 0.021) and BDD (ROE: 43.7 ± 15.7 to 32.5 ± 15.5; p = 0.003 and FROI total score: 47.4 ± 15.3 to 37.8 ± 17.1; p = 0.014). The Hospital Anxiety and Depression Scale exhibited a significant correlation with the preoperative FROI score (r = 0.34, p = 0.005). Patients with positive screenings for depression, anxiety, BDD, and SSD demonstrated compromised QoL during preoperative assessments compared with their negative counterparts, reflecting diminished nasal perception in both esthetic and functional dimensions. Surgeons must be cognizant of these psychological aspects during preoperative evaluations.

Orbital complications of sinusitis in children - Retrospective analysis of an 8.5 year experience

OBJECTIVE

Orbital complications account for approximately 74-85 % of all complications of acute sinusitis, affect the pediatric population more frequently, and can have devastating consequences. In the years following the COVID-19 pandemic (2022, 2023), a high number of children presented to our clinic with orbital complications. 1)Has there been an increase in orbital complications in the post-covid era? 2)To what extent has the use of MRI reduced radiation in pediatric patients?

DESIGN

In our retrospective data analysis, all pediatric patients (age 0-16 years) treated at a university ENT clinic during the period 01/2014-06/2023 who presented with an orbital complication of rhinosinusitis were included. The analysis was descriptive.

RESULTS

Forty-four children with orbital complications of rhinosinusitis were treated during the study period, 14 females and 30 males. Most patients (n = 23, 52 %) presented during the years of the waning Covid-19 pandemic (01/2022 to 06/2023). MRI was the initial imaging modality (n = 22,50 %); CT was performed in 17 of 44 cases (39 %) when surgery was indicated. The most common germ detected was of the Streptococcus species, and the predominant antibiotic administered was amipicillin/sulbactam.

CONCLUSION

The standard operating procedure (SOP) established at our hospital in 2014 was followed in 42/44 cases. Except for 2 cases, CT was performed exclusively when surgery was indicated. Imaging-related radiation could be avoided in 27 patients (61 %). There was a 30 % increase in orbital complications related to sinus infections postpandemically.

Elexacaftor/tezacaftor/ivacaftor improves chronic rhinosinusitis detected by magnetic resonance imaging in children with cystic fibrosis on long-term therapy with lumacaftor/ivacaftor

INTRODUCTION

Previous studies using magnetic resonance imaging (MRI) demonstrated early onset and progression of chronic rhinosinusitis (CRS) from infancy to school age, and response to lumacaftor/ivacaftor (LUM/IVA) therapy in children with cystic fibrosis (CF). However, the effect of elexacaftor/tezacaftor/ivacaftor (ELX/TEZ/IVA) on CRS detected by MRI in children with CF and at least one F508del mutation, and potential incremental effects of ELX/TEZ/IVA compared to LUM/IVA in F508del homozygous children have not been studied.

METHODS

30 children with CF with at least one F508del mutation underwent three longitudinal paranasal sinus MRI before (MRI1), without (n = 16) or with LUM/IVA therapy (n = 14, MRI2), and with ELX/TEZ/IVA therapy (MRI3, mean age at therapy initiation 11.1 ± 3.4y, range 6-16y). MRI were evaluated using the CRS-MRI score.

RESULTS

After therapy initiation with ELX/TEZ/IVA, the prevalence and in maxillary and sphenoid sinuses the dominance of mucopyoceles decreased (35% vs. 0 %, p<0.001 and 26% vs. 8 %, p < 0.05, respectively). This leads to a reduction in mucopyocele subscore (-3.4 ± 1.9, p < 0.001), and sinus subscores in MRI3 (maxillary sinus: -5.3 ± 3.1, p < 0.001, frontal sinus: -1.0 ± 1.9, p < 0.01, sphenoid subscore: -2.8 ± 3.5, p < 0.001, ethmoid sinus: -1.7 ± 1.9, p < 0.001). The CRS-MRI sum score decreased after therapy initiation with ELX/TEZ/IVA by -9.6 ± 5.5 score points (p < 0.001). The strength in reduction of mucopyoceles subscore and CRS-MRI sum score was independent of a pretreatment with LUM/IVA from MRI1-MRI2 (p = 0.275-0.999).

CONCLUSIONS

ELX/TEZ/IVA therapy leads to improvement of CRS in eligible children with CF. Our data support the role of MRI for comprehensive monitoring of CRS disease severity and response to therapy in children with CF.

[Fundamentals and practice of the application of nasal packing in sinonasal surgery]

BACKGROUND AND OBJECTIVES

This paper presents an overview on nasal packing materials which are available in Germany. The current literature is analyzed whether there are robust criteria regarding use nasal packing after sinonasal surgery, whether there are fundamental and proven advantages or disadvantages of products, and what this means in clinical practice.

MATERIALS AND METHODS

Selective literature analysis using the PubMed database (key words "nasal packing", "nasal tamponade", "nasal surgery", "sinonasal surgery", or "sinus surgery"), corresponding text books and resulting secondary literature.

RESULTS AND CONCLUSIONS

Because of systematic methodological shortcomings, the literature does not help in the decision-making about which nasal packing should be used after which kind of sinonasal surgery. In fact, individual approaches for the many different clinical scenarios are recommended. In principle, nasal packing aims in hemostasis, should promote wound healing, and should not result in secondary morbidity. Nasal packing materials should be smooth (non-absorbable materials), inert (absorbable materials), and should not exert excessive pressure. Using non-absorbable packing entails the risk of potentially lethal aspiration and ingestion. For safety reasons inpatient control is recommended as long as this packing is in situ. With other, uncritical packing materials and in patients with special conditions, outpatient control could be justified.

Normative data for interpreting the SNOT-22

Objectives

The Sino-Nasal Outcome Test 22 (SNOT-22) is a validated patient-reported outcome instrument to evaluate the health-related quality of life (HRQoL) in patients with chronic rhinosinusitis (CRS). There are no published normative SNOT-22 scores, limiting its interpretation.

Methods

Symptom scores from 1,000 SNOT-22 questionnaires were analysed by principal component analysis (PCA) and exploratory factor analyses. Data were derived from a survey with 1,000 healthy Europeans (reference cohort) who were recruited using the Respondi panel for market and social science research. This subsample was quoted to the population distribution of the German Microcensus and selected from a non-probability panel.

Results

The overall normative SNOT-22 score can be detected to be 20.2 ± 19.44. Male (18.49 ± 19.15) and older (> 50 years old; 18.3 ± 17.49) participants had overall lower SNOT-22 mean results than females (21.8 ± 19.6) and younger (21.4 ± 20.55) participants, indicating higher levels of satisfaction. PCA proposed two SNOT-22 domains ("physiological well-being" and "psychological well-being"), which explained 65% of the variance.

Conclusions

These are the first published (German) normative scores for the SNOT-22 and provide a clinical reference point for the interpretation of data.

[Validity of the German Menière's Disease Patient-Oriented Symptom Severity Index]

BACKGROUND

The MD POSI is a disease-specific questionnaire to determine the health-related quality of life (HRQoL) of patients with Menière's disease (MD).

OBJECTIVES

Validity and reliability of the German translation of the MD POSI.

MATERIAL AND METHODS

Prospective data analysis of a patient group with vertigo (n = 162), which was treated in the otorhinolaryngology of a University Hospital from 2005-2019. A clinical selection was made according to the new Bárány classification in a "definite" and "probable" Menière's disease. HRQoL was assessed using the German translation of the MD POSI, the Vertigo Symptom Score (VSS) and the Short Form (SF-36). Reliability was measured by Cronbach's α and test-retesting after 12 months and again 2 weeks later. Content and agreement validity were examined.

RESULTS

Cronbach α values greater than 0.9 indicated good internal consistency. There was no statistically significant difference from baseline to 12 months, except for the subscore "during the attack". There were significant positive correlations between the VSS overall/VER/AA and the overall index of the MD POSI and negative significant correlations with the SF-36 domains physical functioning, physical role functioning, social functioning, emotional role functioning, mental well-being. There were low SRM (standardized response mean) values below 0.5.

CONCLUSIONS

The German translation of the MD POSI is a valid and reliable instrument to evaluate the impact of MD on patients' disease-specific quality of life.

Does a tonsillectomy indicated according to the German S2k guideline affect short-term quality of life in adults?

BACKGROUND

Tonsillectomy (TE) for recurrent tonsillitis (RT) is one of the most common surgical interventions. Since 2015, the indication criteria for TE have become much stricter (German S2k guideline). Patient-reported outcome measures (PROMs) of short-term quality of life (QoL) after TE have not yet been investigated.

PURPOSE

To clarify if stringent indication for TE will better identify patients worthy of surgery and patients' QoL.

METHODS

We prospectively studied the Tonsillectomy Outcome Inventory 14 (TOI-14) responses of 38 RT-patients recruited according to the S2k guideline in 2020 and compared their TOI-14 scores with those of a historical RT cohort from 2006 to 2008 and with a healthy middle-European cohort. New RT patients were assessed before, 2, 4, and 14 days and 6 months after TE. TOI-14 was measured as total and as disease-specific score.

RESULTS

From pre- to 6-month postoperative, patients' QoL was significantly different, measured by TOI-14 (49.92 vs. 6.35; p < 0.001) and disease-specific score (60.35 vs. 9.9; p < 0.001). Preoperative disease-specific score was not different from that of the 2nd and 4th postoperative days but from the 14th postoperative day (60.35 vs. 29.26; p < 0.001). The historical cohort had significantly less RT complaints than the new cohort beforehand, but more dissatisfaction in QoL after TE. New TE patients had worse QoL pre- (49.92 vs. 11.78; p < 0.001) but more QoL postoperatively (6.34 vs. 11.78; p = 0.004) than healthy individuals.

CONCLUSIONS

Our results show that the tightening of the indication criteria for TE was justified and that TE patients significantly benefit from this surgery from day 14.

[The complex pediatric middle ear hemangioma]

Hemangiomas in the pediatric middle ear are a rare occurrence. We present the case of a 3-year-old boy with unilateral hearing impairment and recurrent otitis media with effusion due to a hemangioma in the middle ear. This caused a venous sinus thrombosis, osteomyelitis, and mastoiditis. Interdisciplinary treatment was performed. This case shows that even benign lesions in the middle ear can cause severe, life-threatening complications due to the close proximity of important anatomic structures in the middle ear. Every case of asymmetric hearing loss should thus be examined in detail.

Numerical and Machine Learning Analysis of the Parameters Affecting the Regionally Delivered Nasal Dose of Nano- and Micro-Sized Aerosolized Drugs

The nasal epithelium is an important target for drug delivery to the nose and secondary organs such as the brain via the olfactory bulb. For both topical and brain delivery, the targeting of specific nasal regions such as the olfactory epithelium (brain) is essential, yet challenging. In this study, a numerical model was developed to predict the regional dose as mass per surface area (for an inhaled mass of 2.5 mg), which is the biologically most relevant dose metric for drug delivery in the respiratory system. The role of aerosol diameter (particle diameter: 1 nm to 30 µm) and inhalation flow rate (4, 15 and 30 L/min) in optimal drug delivery to the vestibule, nasal valve, olfactory and nasopharynx is assessed. To obtain the highest doses in the olfactory region, we suggest aerosols with a diameter of 20 µm and a medium inlet air flow rate of 15 L/min. High deposition on the olfactory epithelium was also observed for nanoparticles below 1 nm, as was high residence time (slow flow rate of 4 L/min), but the very low mass of 1 nm nanoparticles is prohibitive for most therapeutic applications. Moreover, high flow rates (30 L/min) and larger micro-aerosols lead to highest doses in the vestibule and nasal valve regions. On the other hand, the highest drug doses in the nasopharynx are observed for nano-aerosol (1 nm) and fine microparticles (1-20 µm) with a relatively weak dependence on flow rate. Furthermore, using the 45 different inhalation scenarios generated by numerical models, different machine learning models with five-fold cross-validation are trained to predict the delivered dose and avoid partial differential equation solvers for future predictions. Random forest and gradient boosting models resulted in R² scores of 0.89 and 0.96, respectively. The aerosol diameter and region of interest are the most important features affecting delivered dose, with an approximate importance of 42% and 47%, respectively.

Long-term effects of lumacaftor/ivacaftor on paranasal sinus abnormalities in children with cystic fibrosis detected with magnetic resonance imaging

Introduction: Chronic rhinosinusitis (CRS) usually presents with nasal congestion, rhinorrhea and anosmia impacts quality of life in cystic fibrosis (CF). Especially mucopyoceles pathognomonic for CRS in CF may cause complications such as spread of infection. Previous studies using magnetic resonance imaging (MRI) demonstrated early onset and progression of CRS from infancy to school age in patients with CF, and mid-term improvements of CRS in preschool and school-age children with CF treated with lumacaftor/ivacaftor for at least 2 months. However, long-term data on treatment effects on paranasal sinus abnomalities in preschool and school-age children with CF are lacking. Methods: 39 children with CF homozygous for F508del (mean age at baseline MRI 5.9 ± 3.0 years, range 1-12 years) underwent MRI before (MRI1) and about 7 months after starting lumacaftor/ivacaftor and then annually (median 3 follow-up MRI, range 1-4) (MRI2-4). MRI were evaluated using the previously evaluated CRS-MRI score with excellent inter-reader agreement. For intraindividual analysis ANOVA mixed-effects analysis including Geisser-Greenhouse correction and Fisher's exact test, and for interindividual group analysis Mann-Whitney test were used. Results: The CRS-MRI sum score at baseline was similar in children starting lumacaftor/ivacaftor in school age and children starting therapy at preschool age (34.6 ± 5.2 vs.32.9 ± 7.8, p = 0.847). Mucopyoceles were the dominant abnormality in both, especially in maxillary sinus (65% and 55%, respectively). In children starting therapy in school age the CRS-MRI sum score decreased longitudinally from MRI1 to MRI2 (-2.1 ± 3.5, p < 0.05), MRI3 (-3.0 ± 3.7, p < 0.01) and MRI4 (-3.6 ± 4.7, p < 0.01), mainly due to a decrease in the mucopyoceles subscore (-1.0 ± 1.5, p = 0.059; -1.2 ± 2.0, p < 0.05; -1.6 ± 1.8, p < 0.01; and -2.6 ± 2.8, p = 0.417, respectively). In children starting lumacaftor/ivacaftor in preschool age, the CRS-MRI sum score remained stable under therapy over all three follow-up MRI (0.6 ± 3.3, p = 0.520; 2.4 ± 7.6, p = 0.994; 2.1 ± 10.5, p > 0.999 and -0.5 ± 0.5, p = 0.740; respectively). Conclusion: Longitudinal paranasal sinus MRI shows improvements in paranasal sinus abnormalities in children with CF starting lumacaftor/ivacaftor therapy at school age. Further, MRI detects a prevention of an increase in paranasal sinus abnormalities in children with CF starting lumacaftor/ivacaftor therapy at preschool age. Our data support the role of MRI for comprehensive non-invasive therapy and disease monitoring of paranasal sinus abnormalities in children with CF.

Does a closed reduction improve aesthetical and functional outcome after nasal fracture?

BACKGROUND AND PURPOSES

How closed reduction (CR) to repair a nasal fracture affects the patient's quality of life (QoL) has not been investigated. Here, we assessed QoL before and after CR using disease-specific questionnaires and compared the QoL scores of patients with nasal fractures with normative scores from a reference cohort.

METHODS

This was a prospective study of 96 patients with nasal fractures undergoing CR. Patients were interviewed about aesthetic, functional, and QoL issues before and after surgery using the Functional Rhinoplasty Outcome Inventory (FROI-17) and the Rhinoplasty Outcome Evaluation (ROE). Photographs of the nasal area were taken before and after surgery and reviewed. Data were compared with those from a reference cohort (n = 1000).

RESULTS

Most fractures were type I (80.6%) and most were caused by sport-related accidents (36.5%). The ROE scores increased from 67.3 preoperatively to 73.4 postoperatively (p = 0.001). The FROI-17 also improved, indicating the overall effect of the nose on QoL (p = 0.002). Compared with the reference cohort, patients felt more affected by nasal symptoms before surgery (- 9.37, p = 0.02) than by more general aspects. ROE scores returned to normative values after surgery (p < 0.001). The postoperative cohort had lower scores for the FROI-17 item overall effects of the nose on QoL than the reference cohort did, although the nasal symptom score remained higher in patients than in reference controls.

CONCLUSIONS

This study showed that CR can improve the aesthetical but not the functional outcome of the nose.

[Statement on hospitalization of children after otorhinolaryngologic interventions in Germany : Position paper from the Pediatric Otorhinolaryngology Working Group of the German Society of Otorhinolaryngology, Head and Neck Surgery]

The inpatient care of children after ENT surgery is organized heterogeneously across Germany. In this statement, the working group on Pediatric ENT comments a national survey on the status quo of child care after ENT interventions in German hospitals. The statement should serve as a basis for further interdisciplinary discussion.

Long-term outcomes and quality of life following parotidectomy for benign disease

Objective

Parotidectomy worsens quality of life (QoL) in the short-term, but the long-term impact is unknown. In this study, we analysed the long-term effects of parotidectomy on QoL.

Methods

In this prospective long-term follow-up study, participants were divided into three groups: short-term (ST) follow-up of six weeks, long-term (LT) follow-up of 13 years and short- and long-term (SLT) follow-up. QoL was assessed using the Parotidectomy Outcome Inventory (POI-8). Parotidectomies were classified based on whether the great auricular nerve (GAN) had been preserved or sacrificed.

Results

In total, 164 observations were analysed, 74 in the LT group, 57 in the ST group and 33 in the SLT group. Hypoaesthesia was a major problem and facial palsy was a minor problem. Pain (p < 0.01) and hypoaesthesia (p < 0.001) were significantly lower after 13 years compared with after six weeks, and QoL was higher after 13 years compared with after six weeks (p = 0.04). The disease-specific impairment rate decreased from 70% at short-term follow-up to 30% at long-term follow-up. Removal of the GAN was associated with hypoaesthesia in the ST group (p = 0.028).

Conclusions

Hypoaesthesia has a long-term impact on the QoL, and this should be emphasised during preoperative discussions.

Pulsatile Bi-Directional Aerosol Flow Affects Aerosol Delivery to the Intranasal Olfactory Region: A Patient-Specific Computational Study

The nasal olfactory region is a potential route for non-invasive delivery of drugs directly from the nasal epithelium to the brain, bypassing the often impermeable blood-brain barrier. However, efficient aerosol delivery to the olfactory region is challenging due to its location in the nose. Here we explore aerosol delivery with bi-directional pulsatile flow conditions for targeted drug delivery to the olfactory region using a computational fluid dynamics (CFD) model on the patient-specific nasal geometry. Aerosols with aerodynamic diameter of 1 µm, which is large enough for delivery of large enough drug doses and yet potentially small enough for non-inertial aerosol deposition due to, e.g., particle diffusion and flow oscillations, is inhaled for 1.98 s through one nostril and exhaled through the other one. The bi-directional aerosol delivery with steady flow rate of 4 L/min results in deposition efficiencies (DEs) of 50.9 and 0.48% in the nasal cavity and olfactory region, respectively. Pulsatile flow with average flow rate of 4 L/min (frequency: 45 Hz) reduces these values to 34.4 and 0.12%, respectively, and it mitigates the non-uniformity of right-left deposition in both the cavity (from 1.77- to 1.33-fold) and the olfactory region (from 624- to 53.2-fold). The average drug dose deposited in the nasal cavity and the olfactory epithelium region is very similar in the right nasal cavity independent of pulsation conditions (inhalation side). In contrast, the local aerosol dose in the olfactory region of the left side is at least 100-fold lower than that in the nasal cavity independent of pulsation condition. Hence, while pulsatile flow reduces the right-left (inhalation-exhalation) imbalance, it is not able to overcome it. However, the inhalation side (even with pulsation) allows for relatively high olfactory epithelium drug doses per area reaching the same level as in the total nasal cavity. Due to the relatively low drug deposition in olfactory region on the exhalation side, this allows either very efficient targeting of the inhalation side, or uniform drug delivery by performing bidirectional flow first from the one and then from the other side of the nose.

Qualification of the Low-pressure Cold Gas Spraying for the Additive Manufacturing of Copper-Nickel-Diamond Grinding Wheels

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.

Health status and labour force participation among older workers: a growth curve analysis

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.

How to predict the outcome of septorhinoplasty? A normative study of ROE and FROI-17 scores

Objective

Normative values of patient-reported outcome instruments are needed to identify good candidates for rhinoplasty. Rhinoplasty Outcome Evaluation (ROE) and Functional Rhinoplasty Outcome Inventory-17 (FROI-17) are disease-specific questionnaires that evaluate quality of life in patients undergoing rhinoplasty.

Methods

The reference cohort contained 1,000 participants, selected from a non-probability panel. Normative ROE and FROI-17 scores from this reference cohort were compared with ROE and FROI-17 scores from a patient cohort before (n = 104) and 6 (n = 55) and 12 months (n = 32) after septorhinoplasty.

Results

Mean FROI-17 scores (± SD) were: overall score, 20.8 ± 17; nasal symptoms, 16.8 ± 7; general symptoms, 24.8 ± 22; and self-confidence, 16.4 ± 21. The ROE total score was 73.1 ± 16. Normative values differed significantly from the preoperative ROE and FROI-17 scores of septorhinoplasty patients (p < 0.01). Except for the FROI-17 general score at 12 months postoperatively (p = 0.004), there were no significant differences between normative ROE/FROI-17 and septorhinoplasty scores postoperatively, indicating that they returned to normalcy.

Conclusions

Normative scores for ROE and FROI-17 provide a reference point from which to identify patients who are most likely to benefit from rhinoplasty.

Cross-cultural adaptation and validation of the 22-item sinonasal outcome test (SNOT-22) in German-speaking patients: a prospective, multicenter cohort study

Purpose

Chronic rhinosinusitis (CRS) is a common condition associated with a significant reduction of the health-related quality of life. One of the most widely used assessment tools in CRS is the disease-specific, health-related questionnaire SNOT-22. The aim of this study was to translate and validate the SNOT-22 into the German language.

Methods

The questionnaire was translated using the forward–backward translation technique. After the translation its reliability, validity, and sensitivity were evaluated. For this purpose, the questionnaire was completed by patients diagnosed with CRS before, 3 months and 1 year after endoscopic sinus surgery and by healthy individuals as controls at three university hospitals in Germany. The individual scores of the questionnaire before surgery was correlated with the Lund–Mackay score as well as a global disease-specific question.

Results

A total of 139 CRS patients and 31 healthy individuals participated in the study. Internal consistency at all timepoints was very good, with Cronbach’s alpha scores of 0.897, 0.941, and 0.945. The questionnaire was able to discriminate between CRS patients and control subjects (p < 0.0001) and scores improved significantly 3 month and 1 year after sinus surgery (p < 0.0001), indicating a good test–retest reliability, validity, and responsiveness. A significant correlation to the single global disease-specific question could be found (p < 0.0001), but no correlation with the Lund–Mackay score.

Conclusion

The German Version of the SNOT-22 is a reliable, valid, and sensitive instrument for measuring health-related quality of life in patients with CRS. It can be recommended for clinical practice and outcome research for German-speaking patients.

Chronic rhinosinusitis with nasal polyps is associated with impaired TMEM16A-mediated epithelial chloride secretion

BACKGROUND

Chronic rhinosinusitis with nasal polyps (CRSwNP) is one of the most common chronic disorders with limited therapeutic options. However, the pathogenesis of CRSwNP remains poorly understood.

OBJECTIVE

We sought to determine the role of abnormalities in nasal epithelial ion transport in primary epithelial cultures and patients with CRSwNP.

METHODS

We studied epithelial ion transport and transcript levels of the Cl^- channels cystic fibrosis transmembrane conductance regulator and transmembrane protein 16A (TMEM16A) in human primary nasal epithelial cultures of patients with CRSwNP and healthy controls. Furthermore, we determined expression levels of proinflammatory cytokines that have been implicated in the regulation of epithelial ion channels (IL-1β, INF-γ, TNF-α, IL-13) and studied effects of the key T_H2 signaling molecule IL-13 in CRSwNP and control nasal epithelial cultures. Finally, we measured in vivo nasal potential difference to compare epithelial ion transport in patients with CRSwNP and controls.

RESULTS

Bioelectric studies demonstrated that Ca²⁺-activated Cl^- secretion was reduced in CRSwNP versus control nasal epithelial cultures. Transcript levels of IL-13 and the Ca²⁺-activated Cl^- channel TMEM16A were increased in CRSwNP cultures. Stimulation with IL-13 increased TMEM16A expression further and restored Ca²⁺-activated Cl^- secretion in CRSwNP cultures. Nasal potential difference measurements demonstrated reduced Ca²⁺-activated Cl^- transport in patients with CRSwNP versus controls.

CONCLUSIONS

This study demonstrates that TMEM16A-mediated Ca²⁺-activated Cl^- secretion is reduced in primary nasal epithelial cultures and nasal epithelia of patients with CRSwNP. Our data suggest that the Ca²⁺-activated Cl^- channel TMEM16A may be implicated in the pathogenesis and serve as a novel therapeutic target in patients with CRSwNP.

Clivus chordomas: Heterogeneous tumor extension requires adapted surgical approaches

OBJECTIVE

Clivus chordomas are semi-malignant, but infiltratively growing tumors. Currently, a widely-accepted treatment concept encompasses maximal, but safe, surgical resection and radiotherapy. Caused by the size and the tumor extension, different surgical approaches, especially in recurrent cases, might be necessary.

METHODS

Retrospective review of 50 patients on whom 70 surgeries were performed: 29 in primary and 41 in recurrent cases. Based on MRI images, all cases were asserted according to the size and the extension of the tumor. Used surgical approaches were evaluated. Postoperative complications, neurological function prior to and after the surgery, the extent of tumor resection on postoperative MR images were assessed and progression-free survival was calculated.

RESULTS

Tumor size was estimated as small (< 5 cm³) in 8, as medium (5-20 cm³) in 21, as large (20-100 cm³) in 17, and as giant (> 100 cm³) in 4 patients. Most frequently used surgical approaches in primary cases were the transsphenoidal one and midfacial degloving (51.7 % and 17.2 %, respectively). In recurrent cases, dependent on the tumor extension, transsphenoidal (21.9 %), retrosigmoidal (29.3 %), and pterional (19.5 %) approaches, as well as midfacial degloving (17.1 %) were used. Due to the vast tumor extension and infiltration, gross total or near total resection could be achieved in 12 patients (24 %), only. There was no mortality and no major complications in primary cases. In recurrences, however, postoperative hemorrhages and strokes emerged in 4.9 % and 7.1 %. Minor complications occurred in 17.1 % and were dominated by CSF leaks (12.2 %), both in primary in recurrent cases. While most cranial nerve impairments were caused by tumor infiltration of the cavernous sinus, and hence have not improved by treatment, the sixth nerve palsy as a consequence of tumor mass compression, could significantly be improved by surgery. Following surgery, patients were subjected to radiotherapy (68.9 % for primary cases, and 36.6 % for recurrences) mainly with carbon ions. Overall, 5-year progression-free survival was 44.7 %.

CONCLUSION

Caused by the heterogenous pattern of growth of clivus chordomas, surgical approaches should be chosen individually. Vast and infiltrative tumor extension constitute major limitations of surgical resection, and hence result in poor progression-frees survival.

Normative tonsillectomy outcome inventory 14 values as a decision-making tool for tonsillectomy

Purpose

The study aimed to determine normative values for the Tonsillectomy Outcome Inventory 14 (TOI-14) in a healthy middle-European cohort. We also compared these generated values with TOI-14 scores from a patient population with recurrent tonsillitis (RT) and explored the factorial structure of the TOI-14.

Methods

We systematically studied the responses of healthy individuals (reference cohort) and patients with RT (clinical cohort) to the TOI-14 survey. The reference cohort contained 1000 participants, who were recruited using the Respondi panel for market and social science research. This subsample was quoted to the population distribution of the German Microcensus and selected from a non-probability panel. Tonsillitis patients were assessed before and 6 and 12 months after tonsillectomy.

Data were analysed using principal component and exploratory factor analyses.

Results

The PCA revealed three TOI-14 domains (physiological, psychological and socio-economic), which explained 73% of the total variance. The reference cohort perceived a good quality of life (QOL) with a TOI-14 total score of 11.8 (physiological: 8.0, psychological: 5.8, and socio-economic subscale score: 13.9). TOI-14 scores were higher in the patient cohort, indicating that the TOI-14 discriminates between patients with RT and healthy individuals with no RT. Age and female gender significantly influenced the total TOI-14 score, especially in the psychological (age) and socio-economic (gender) subscales.

Conclusion

We have developed a set of normative values that, together with the TOI-14, can determine the disease burden indicating tonsillectomy.

Tumor Control and Quality of Life in Skin Cancer Patients With Extensive Multilayered Nasal Defects

OBJECTIVES

The reconstruction after nasal skin cancer (NSC) resection is often practiced differently. The objective of this study is to evaluate the influence of patient-, tumor- and management-related factors on the role of surgery and choice of reconstruction.

METHODS

This was a monocentric retrospective study of patients who were diagnosed with a NSC (squamous cell or basal cell carcinoma) and suffered from an extended defect after ablative surgery between 2003 and 2013. Twenty-five patients were included. Tumors were staged using the Union for International Cancer Control (eighth edition) TNM classification for primary cutaneous skin cancer of the head and neck. Preferred treatment was surgery in all patients. Health-related quality of life (HRQoL) measurement was evaluated by one generic (36-Item Short Form Health Survey [SF-36]) and two organ-specific questionnaires (Rhinoplasty Outcome Evaluation [ROE] and Functional Rhinoplasty Outcome Inventory 17 [FROI-17]) after therapy. Survival data were estimated by the Kaplan-Meier method and statistical analysis was performed by log-rank, analysis of variance, Levene's and t-tests. The median follow-up time was 2.1 years.

RESULTS

According to the Union for International Cancer Control classification, 13 of 25 tumors were staged as pT1 (52%), four as pT2 (16%), seven as pT3 (28%) and one as pT4a (4%). Seventy-two percent of patients (n=18) chose plastic reconstruction, and for the remaining 28% (n=7) of the patients opted for an implant-retained prosthesis. The overall survival was 69.5% after 5 years, the 5-year recurrence-free survival was 90.9% and the 5-year disease-specific survival was 100%. There was no significant difference in the HRQoL outcome between both rehabilitation methods.

CONCLUSION

Surgery in NSC gives an excellent oncologic prognosis. Nasal reconstruction and prostheses are both very viable options depending on tumor stage and biology, the patient's wishes as well as the experience of the surgeon.

Validating the Xerostomia Inventory in a radiation-induced xerostomia population in German language

OBJECTIVES

Though xerostomia is a frequent oral symptom, there is no validated disease-specific questionnaire in German. The purpose of this study was to translate and validate versions of the Xerostomia Inventory and the Summated Xerostomia Inventory in a German-speaking population.

PARTICIPANTS AND METHODS

Thirty-nine patients including 18 patients suffering from radiation-induced xerostomia enrolled in this study. Both questionnaires were translated into German language according to international accepted guidelines. For validation, we evaluated reliability, validity, and responsiveness using the COSMIN manual for cross-cultural adaptation.

RESULTS

Cronbach's α was 0.92 for XI and 0.91 for SXI, showing both high internal consistency. Patients suffering from xerostomia showed significantly higher average scores demonstrating its discriminant validity. Confirmatory factor analysis showed excellent "goodness-of-fit" values for SXI and good to moderate values for XI, confirming the assumed factor structures. The Xerostomia Inventory and its summated version both showed excellent test-retest reliability in the non-xerostomia group (ICC = 0.85 and 0.84).

CONCLUSIONS

The XI and SXI in their cross-cultural adapted versions are the first validated self-report assessments for xerostomia in German language. They are characterized by practical design and can be easily interpreted by the treating physician.

[Social reimbursement-the Spanish-German ENT Society's (SDGHNO) Latin America project]

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.

[State of the art of quality-of-life measurement in patients with chronic otitis media and conductive hearing loss]

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.

[Development and validation of the Stapesplasty Outcome Test 25 (SPOT-25)]

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.

[Acupuncture in posttonsillectomy pain : A prospective double-blind randomized controlled trial. German version]

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.

Prolongation of working life and its effect on mortality and health in older adults: Propensity score matching

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.

Quality of life after nasal cancer resection - surgical versus prosthetic rehabilitation

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.

International validation of the revised European Organisation for Research and Treatment of Cancer Head and Neck Cancer Module, the EORTC QLQ-HN43: Phase IV

BACKGROUND

We validated the new European Organisation for Research and Treatment of Cancer Quality of Life Head and Neck Module (EORTC QLQ-HN43).

METHODS

We enrolled 812 patients with head and neck cancer from 18 countries. Group 1 completed the questionnaire before therapy, and 3 and 6 months later. In group 2 (survivors), we determined test-retest reliability using intraclass correlation coefficients (ICC). Internal consistency was assessed using Cronbach's Alpha, the scale structure with confirmatory factor analysis, and discriminant validity with known-group comparisons.

RESULTS

Cronbach's alpha was >0.70 in 10 of the 12 multi-item scales. All standardized factor loadings exceeded 0.40. The ICC was >0.70 in all but two scales. Differences in scale scores between known-groups were >10 points in 17 of the 19 scales. Sensitivity to change was found to be sufficient in 18 scales.

CONCLUSIONS

Evidence supports the reliability and validity of the EORTC QLQ-HN43 as a measure of quality of life.

Quality of Life Gain After Septorhinoplasty: An Analysis of Health Utility and Cost Utility Values Associated with Septorhinoplasty

PURPOSE

Septorhinoplasty is a common procedure performed in rhinology and facial plastic surgery. Despite this, the health benefits associated with the procedure remain controversial. In this study, a health utility assessment of patients undergoing septorhinoplasty was performed. Health gains associated with the procedure, and the cost at which they were acquired, were also determined.

METHODS

Sixty-seven patients undergoing septorhinoplasty at a German tertiary-level hospital were included in the study. Study participants completed the Short Form 36 (SF-36) and satisfaction questionnaires before and 12 months after septorhinoplasty. The Short Form six-dimensional (SF-6D) instrument was used to acquire quality-adjusted life year (QALY) values from SF-36 responses, thus allowing estimation of pre- and post-operative health utilities. Health utility gains after septorhinoplasty were determined and combined with cost data to estimate cost per QALY gained.

RESULTS

Patients undergoing septorhinoplasty reported mean pre-operative health utility values of 0.70 pre-operatively and 0.74 post-operatively resulting in health gains of 0.04 QALYs. Patients satisfied with their procedures had significant health utility gains, while dissatisfied patients did not experience any significant gains. The cost of septorhinoplasty to statutory health insurance was €3487.69. When compared to the baseline, the incremental utility ratio for septorhinoplasty was €94,797.30 per QALY gained.

CONCLUSIONS

This study successfully estimated the health utilities and gains associated with septorhinoplasty. The findings indicate that the procedure has associated health gains but at a high cost-utility ratio. These values provide a reference point for further much-needed economic evaluations.

Impact of sialendoscopy on improving health related quality of life in patients suffering from radioiodineinduced xerostomia

Introduction: Xerostomia following radioiodine therapy (RIT) in patients suffering from differentiated thyroid cancer is a common side effect in 2 % to 67 % of patients treated with radioiodine (I-131). In order to evaluate the impact of sialendoscopy on health related quality of life (HRQOL) in patients suffering from therapy induced sialadenitis and xerostomia, we analyzed findings from two dedicated questionnaires (Xerostomy Questionnaire XQ and Xerostomy Inventory XI) in patients before and three months after sialendoscopy. Procedures: In total, 12 patients suffering from differentiated thyroid carcinoma (10 women and 2 men) were evaluated. All patients had experienced conservative management. Patients were offered a sialendoscopy procedure if no major contradictions were present. Patients who denied the procedure formed the control group. Pre- and (three months) postoperative HRQOL was measured with the Patient Reported Outcome Measures (PROM) Xerostomia Questionnaire (XQ) and the Xerostomia Inventory (XI), as well as by a pre- and post-interventional salivary gland scintigram. Patients were graded according to their sialendoscopical findings. Results: Interventional group presented with significant improvements in HRQOL measurements regarding XQ and XI-scores three months postoperatively. Control group showed no significant changes in the XQ or the XI scores. Number of RIT and cumulative activity of I-131 did not correlate with higher disease grade in regards to sialendoscopical findings nor did it correlate with higher XQand XI scores. Pre- and post-interventional salivary gland scintigram stated that parotid glands are more severely damaged than submandibular glands (SMG), but no significant scintigraphically changes could be detected after sialendoscopy. Conclusion: Sialendoscopy in patients suffering from therapy induced sialadenitis and xerostomia seems to be beneficial when evaluating the impact on HRQOL. Functional parameters measured by salivary gland scintigram did not show significant changes in post-interventional scintigrams.

[CF Lung Disease - a German S3 Guideline: Module 2: Diagnostics and Treatment in Chronic Infection with Pseudomonas aeruginosa]

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.

Patients Screening Positive for Body Dysmorphic Disorder Show No Significant Health-Related Quality of Life Gain after Functional Septorhinoplasty at a Tertiary Referral Center

Body dysmorphic disorder (BDD) is a psychiatric disorder defined by an excessive concern about one's physical appearance, especially regarding slight or imagined abnormities of the body. This study was conducted to compare postoperative quality of life (QOL) changes after primary septorhinoplasty among patients screening positive and those screening negative for BDD. Two common instruments for the screening of BDD were used namely the Dysmorphic Concern Questionnaire (DCQ) and the BDD Concern Questionnaire (BDDQ). For the determination of QOL changes, three validated screening instruments were used. The Functional Rhinoplasty Outcome Inventory (FROI-17) and the Rhinoplasty Outcomes Evaluation (ROE) were used as disease-specific instruments and the Short Form 36 Health Survey (SF-36) was used as a general instrument. All patients completed the FROI-17, the ROE, and the SF-36 preoperatively and 60 months postoperatively. The BDD questionnaires were singularly obtained 60 months after surgery. The authors identified 9.8% of our patients with a possible BDD diagnosis. The patients screening positive for BDD showed significantly lower ROE scores postoperatively, compared with those screening negative for BDD. QOL gains detected by the disease-specific instruments (ROE and FROI-17) were only significant in the non-BDD group. No significant QOL gains were detectable with the FROI-17, the ROE, and the SF-36 in the BDD group. In patients screening negative for BDD, QOL, as measured with the SF-36, improved significantly in five categories: physical functioning, role-functioning physical, bodily pain, general health, and social functioning. Patients screening positive for BDD did not improve in any categories of the general SF-36 questionnaire. Instead, their score in the "mental health" category was significantly lower 5 years after their surgery compared with preoperatively. Patients retrospectively screening positive for BDD in our cohort did not improve in QOL postoperatively. Alternative nonsurgical treatments such as cognitive behavioral treatment and/or selective serotonin reuptake inhibitors have been reported to be effective and should be considered as the treatment of choice. Some studies suggest that a smaller subgroup of BDD patients may benefit from functional rhinoplasty. Further research and larger long-term prospective outcome studies are needed to understand the influence of BDD symptoms on postoperative satisfaction and QOL changes after septorhinoplasty.

Impact of Gender on General Health-Related Quality of Life in Patients with Chronic Sinusitis

Background

The aim of this study was to evaluate the impact of gender on health-related quality of life (HRQOL) in patients with chronic sinusitis

Methods

A prospectively administered survey was performed. For measuring HRQOL, we used the German versions of the Short Form 36 (SF-36; eight subscales) and the European Quality of Life—5 Dimensions (EQ-5D) (two subscales). For all SF-36 subscales we used norm-based scoring of the general German population.

Results

One hundred twenty-three patients (45 women and 78 men) underwent HRQOL evaluation at baseline (preoperatively) and 3 months after endonasal sinus surgery. Compared with male patients, female patients scored a significantly worse baseline in all SF-36 and one EQ-5D subscales and 3 months later in only one SF-36 subscale. Compared with the norm-based scores, both women's and men's SF-36 scores reached normal levels in seven subscales after 3 months.

Conclusion

Compared with men, women assessed preoperative HRQOL as being worse. Most women's and men's SF-36 subscales reached normal levels at the 3-month follow-up.

Long-term quality of life changes after primary septorhinoplasty

PURPOSE

Health-related quality of life measurements are gaining in importance in clinical medicine. Little is known about the long-term quality of life changes after septorhinoplasty. This study was designed to analyse the long-term quality of life impacts of septorhinoplasty, using disease-specific instruments-rhinoplasty outcome evaluation (ROE) and Functional Rhinoplasty Outcome Inventory-17 (FROI-17); as well as a generic instrument-Short-Form 36 Health Survey (SF-36).

METHODS

Patients completed the FROI-17, the ROE and the SF-36 preoperatively and at 12 and 60 months postoperatively. General demographic and clinical information (age, gender, allergies, medication, medical and surgical history) were collected from all patients.

RESULTS

We report a significant increase in disease-specific QOL after primary septorhinoplasty (as measured with the ROE & FROI-17) and in two scales of the SF-36 generic instrument (role-functioning physical and mental health) 1 year after surgery. Our patients showed further significant increase in disease-specific QOL (FROI-17) after their primary septorhinoplasty (1 year vs. 5 years postoperatively). SF-36 results showed significant improvements 5 years postoperatively (compared to preoperative scores) in six out of eight scales (physical functioning, role-functioning physical, bodily pain, vitality, social functioning and mental health).

CONCLUSION

Septorhinoplasty can improve disease-specific and non-disease-specific QOL in the short- and long-term postoperative period. These improvements remain measurable 5 years after surgery.
