[Basics in diagnostics and therapy of allergic diseases for ENT consultations]. / Grundlagen der Allergologie für die HNO-Sprechstunde.

Allergies play a pivotal role in the daily practice of ENT specialists. Allergic symptoms induced by inhalant allergens are widespread in the population and can manifest through a wide range of symptoms, including rhinorrhea, sneezing, conjunctival redness, cough and dyspnea. Inconsistent diagnosis and treatment of allergic conditions can lead to reduced quality of life, decreased work performance, and socioeconomically significant secondary diseases. In addition to the medical history, the skin prick test and serological IgE diagnostics are the most important diagnostic procedure for detecting type-I allergies. To clarify clinical relevance, molecular diagnostics and nasal provocation testing may be employed. The key to effective treatment lies in a comprehensive allergological diagnosis coupled with a detailed patient history. General treatment recommendations such as allergen avoidance and nasal irrigation should complement pharmacological therapy. In the treatment of allergic rhinitis topical steroids are first line treatment options. The primary goal of treatment is symptom control, and if control is insufficient, causal therapy through specific allergen immunotherapy is recommended. Challenges in the ENT clinic involve selecting the necessary diagnostics and appropriate, effective treatments. Hence, using diagnostic and treatment algorithms, as well as standardized patient history questionnaires, can serve as invaluable tools in daily patient interactions, especially considering limited time availability.

[The potential of complementary music interventions in patients with head and neck cancer]. / Das Potenzial komplementärer Musikinterventionen bei Patienten mit malignen Kopf-Hals-Tumoren.

PURPOSE: The established treatment regimen for patients suffering from cancer in the head and neck region often leads to physical and mental health problems and therefore can significantly reduce the quality of life (QoL) in these patients. The available data indicate that additional complementary treatments, such as music interventions, may improve patients' QoL and compliance and reduce symptoms during therapy. METHODS: Anonymous data collection using a self-designed questionnaire was conducted in patients suffering from cancer in the head and neck area in our outpatient department. The questionnaire particularly asked the patients about their need and interest in music interventions during therapy. RESULTS: In total, 138 patients were consecutively enrolled in the study. The mean age was 64.9 years, including 68.1% men and 31.9% women. Only 11.5% listened to music regularly during their therapy at the time of data collection, yet 52.2% stated that they would be interested in music interventions. Patients especially conceived the relaxing and encouraging effects from listening to music. Most patients would prefer group therapies (56%) or listening to their own music (36.6%). CONCLUSION: Our data suggest that there is a need for music interventions in patients suffering from cancer in the head and neck, as they anticipate they would experience positive effects, including reduced somatic and non-somatic symptoms and improved QoL. The lack of homogenous data emphasizes the need for further trials in the field of complementary music interventions to establish science-based concepts in the future.

Methods for measuring pre-, intra-, and postoperative skin thickness for cochlear implants.

Objective: This study was conducted to determine whether there is a reliable method for measuring the thickness of the retroauricular skin before, during, and after cochlear implantation, which allows the assessment of the optimal force of the external magnet of the cochlear implant (CI). Methods: The retroauricular skin thickness of 83 patients who received a CI was measured using three different methods. The thickness was measured on pre- and postoperative CT images, as well as intraoperatively. The magnet category chosen by the surgeon was recorded when the implant was switched on and during the first follow-up visit. Correlation analyses were performed on the different skin thickness measurements and between the skin thickness and magnet strength categories. Results: Only six patients required an exchange of the magnet until the follow-up. Although the median absolute thickness differed significantly between the three measures (p < 0.0001), their thickness values showed highly significant correlations (Pearson's r = 0.457-0.585; p < 0.01). In addition, magnet strength, was significantly correlated with the flap thickness determined pre-, post-, and during surgery. The lowest correlation with magnet strength was found in the intraoperative needle method. Conclusion: All three measurements methods provided a suitable base for determining the ideal magnetic force. However, of particular interest were the pre- and postoperative CT measurements. The first enabled the early assessment of the required magnetic strength and thus a timely postoperative supply, whereas the latter helped to estimate the need for magnetic strength reduction during follow-up care and the feasibility of an early swith-on.

Cocaine Reduces Ciliary Beat Frequency of Human Nasal Epithelial Cells.

BACKGROUND/AIM: Cocaine is a widely used recreational drug and is known for its nasal complications including epithelial, cartilage and bone damage. The aim of the study was to analyze the impact of cocaine on ciliary beat frequency (CBF) of human nasal epithelial cells and therefore better understand its side effects on nasal mucosa. MATERIALS AND METHODS: Nasal epithelial cells of 21 healthy subjects were harvested and exposed in vitro to cocaine hydrochloride solutions ranging from 0.875% to 7%. High-speed video footage was acquired with phase contrast microscopy and CBF was analyzed with Sissons-Ammons Video Analysis (SAVA) software. RESULTS: All tested concentrations led to a significant reduction in CBF compared to the control. Effects increased over time and with concentration. A mechanical inhibition of cilia by cocaine crystals was also observed. CONCLUSION: We assume that CBF reduction is part of the pathomechanism leading to nasal complications in cocaine abuse. Considering these results, clinical usage of cocaine should be critically evaluated and restricted to select cases only.

Early Migration Predicts Aseptic Loosening of Cementless Femoral Stems: A Long-term Study.

BACKGROUND: Excessive early migration of cemented stems and cups after THA has been associated with poor long-term survival and allows predictable evaluation of implant performance. However, there are few data regarding the relationship between early migration and aseptic loosening of cementless femoral components, and whether early migration might predict late failure has not been evaluated, to our knowledge. Einzel-Bild-Röntgen-Analyse-femoral component analysis (EBRA-FCA) is a validated technique to accurately measure axial femoral stem migration without the need for tantalum markers, can be performed retrospectively, and may be a suitable tool to identify poor performing implants before their widespread use. QUESTIONS/PURPOSES: We asked: (1) Is axial migration within the first 24 months as assessed by EBRA-FCA greater among cementless stems that develop aseptic loosening than those that remain well fixed through the second decade; (2) what is the diagnostic performance of implant migration at 24 months postoperatively to predict later aseptic loosening of these components; and (3) how does long-term stem survivorship compare between groups with high and low early migration? METHODS: We evaluated early axial stem migration in 158 cementless THAs using EBRA-FCA. The EBRA-FCA measurements were performed during the first week postoperatively (baseline measurement) and at regular followups of 3, 6, and 12 months postoperatively and annually thereafter. The mean duration of followup was 21 years (range, 18-24 years). The stems studied represented 45% (158 of 354) of the cementless THAs performed during that time, and cementless THAs represented 34% (354 of 1038) of the THA practice during that period. No patient enrolled in this study was lost to followup. Multivariate survivorship analysis using Cox's regression model was performed with an endpoint of aseptic loosening of the femoral component. Loosening was defined according to the criteria described by Engh et al. and assessed by two independent observers. Patients with a diagnosis of prosthetic joint infection were excluded. Receiver operating characteristic (ROC) curve analysis was used to evaluate diagnostic performance of axial stem migration 1, 2, 3, and 4 years postoperatively as a predictor of aseptic loosening. Survivorship of hips with high (≥ 2.7 mm) and low (< 2.7 mm) migration was compared using a competing-events analysis. RESULTS: Femoral components that had aseptic loosening develop showed greater mean distal migration at 24 months postoperatively than did components that remained well fixed throughout the surveillance period (4.2 mm ± 3.1 mm vs 0.8 mm ± 0.9 mm; mean difference, 3.4 mm, 95% CI, 2.5-4.4; p ≤ 0.001). Distal migration at 24 months postoperatively was a strong risk factor for aseptic loosening (hazard ratio, 1.98; 95% CI, 1.51-2.57; p < 0.001). The associated overall diagnostic performance of 2-year distal migration for predicting aseptic loosening was good (area under the ROC curve, 0.86; 95% CI, 0.72-1.00; p < 0.001). Sensitivity of early migration measurement was high for the prediction of aseptic loosening during the first decade after surgery but decreased markedly thereafter. Stems with large amounts of early migration (≥ 2.7 mm) had lower 18-year survivorship than did stems with little early migration (29% [95% CI, 0%-62%] versus 95% [95% CI, 90%-100%] p < 0.001). CONCLUSIONS: Early migration, as measured by EBRA-FCA at 2 years postoperatively, has good diagnostic capabilities for detection of uncemented femoral components at risk for aseptic loosening during the first and early second decades after surgery. However, there was no relationship between early migration patterns and aseptic loosening during the late second and third decades. EBRA-FCA can be used as a research tool to evaluate new cementless stems or in clinical practice to evaluate migration patterns in patients with painful femoral components. LEVEL OF EVIDENCE: Level III, diagnostic study.
