Abstract
Human temporal bone specimens are used in experiments measuring the sound transfer of the middle ear, which is the standard method used in the development of active and passive middle ear implants. Statistical analyses of these experiments usually require that the TB samples are representative of the population of non-pathological middle ears. Specifically, this means that the specimens must be mechanically well-characterized. We present an in-depth statistical analysis of 478 data sets of middle ear transfer functions (METFs) from different laboratories. The data sets are preprocessed and various contributions to the variance of the data are evaluated. We then derive a statistical range as a reference against which individual METF measurements may be validated. The range is calculated as the two-sided 95% tolerance interval at audiological frequencies. In addition, the mean and 95% confidence interval of the mean are given as references for assessing the validity of a sample group. Finally, we provide a suggested procedure for measuring METFs using the methods described herein.

Abstract
Objectives Medulloblastoma (MB) is treated with surgery and chemotherapy, with or without irradiation, but unfortunately >20% of the patients are not cured, and treatment comes with serious long-term side effects, so novel treatments are urgently needed. Phosphoinositide 3-kinases (PI3K), fibroblast growth factor receptors (FGFR), and cyclin-D kinases (CDK) play critical roles in cancer, and especially PI3K is crucial in MB, so here targeted therapies against them were explored. Methods MB cell lines DAOY and UW228-3 were exposed to PI3K (BYL719), FGFR (JNJ-42756493), and CDK4/6 (PD-0332991) inhibitors, as single or combined treatments, and their viability, cell confluence, apoptosis, and cytotoxicity were examined. Moreover, the inhibitors were combined with cisplatin, vincristine, or irradiation. Results Single treatments with FGFR, PI3K, or CDK4/6 inhibitors decreased viability and proliferation slightly; however, when combining two inhibitors, or the inhibitors with irradiation, sensitivity was enhanced and lower doses could be used. A more complex pattern was obtained when combining the inhibitors with cisplatin and vincristine. Conclusions The data suggest that combination treatments with PI3K, FGFR, and CDK4/6 inhibitors for MB could be beneficial and their use should be pursued further. Likewise, their combination with irradiation gave positive effects, while the addition of cisplatin and vincristine resulted in more complex patterns, which need to be investigated further.

Abstract
Medulloblastoma (MB) is the most frequent malignant brain tumor in children. Treatment of MB is based on histopathological and molecular stratification, and includes surgical intervention, often with craniospinal irradiation and adjuvant chemotherapy. Unfortunately, however, this treatment leads to a high morbidity rate, and it does not cure all patients either, with around 30% succumbing to their disease. With improved cancer genomics and better molecular characterization, MB has been classified into four major subgroups, wingless-activated, sonic hedgehog-activated, Group 3, and Group 4, with each group consisting of additional subtypes. Recently disclosed genetic drivers of MB may in the future help improve treatment, and in this way reduce therapy-related toxicity. In this review, we describe the heterogeneity of the MB subgroups, and potential new options for targeted therapy.

Abstract
Neurinomas in the nose and the nasal sinuses are rare. In the present work, we present an exceedingly rare case of a disfiguring neurinoma involving the nasal columella. Treatment of choice is complete resection of the tumor. For an optimal view for tumor resection and esthetic and functional reconstruction, we recommend an open surgical approach.

Abstract
Balloon dilation of the Eustachian tube has been recently introduced as a novel and minimally invasive method for treating chronic obstructive Eustachian tube dysfunction. For the first time worldwide, we assessed the role of this technique in the treatment of children with Eustachian tube dysfunction who did not respond to other treatments. We retrospectively analysed the medical records of 60 children (mean age: 6.3 years, range: 28 months to 12 years) who underwent balloon dilation of the Eustachian tube using the Bielefeld balloon catheter. In addition, the parents of a further 66 children who underwent balloon dilation (mean age: 8 years, range: 4 to 13 years) were asked to complete a standardised written questionnaire and were interviewed by telephone about the postoperative course of their children. There were no complications during surgery. Clinical symptoms improved in more than 80% of patients. No patient reported a deterioration of symptoms. Of the participating parents, 81.3% were very satisfied or satisfied with the outcome of treatment. Balloon dilation is a rapid, simple and safe method for the treatment of both adults and children with Eustachian tube dysfunction that does not respond to other treatments. Further studies, ideally multicentre studies, are required in order to optimise the definition of existing and potential new indications for this treatment approach and to establish this treatment in the management of children with refractory chronic Eustachian tube dysfunction.

Abstract
BACKGROUND Psoriasiform and eczematous eruptions are the most common dermatological adverse reactions linked to anti-tumour necrosis factor (TNF)-α therapy. Yet, a detailed characterization of their immune phenotype is lacking. OBJECTIVES To characterize anti-TNF-α-induced inflammatory skin lesions at a histopathological, cellular and molecular level, compared with psoriasis, eczema (atopic dermatitis) and healthy control skin. METHODS Histopathological evaluation, gene expression (quantitative real-time polymerase chain reaction) and computer-assisted immunohistological studies (TissueFAXS) were performed on 19 skin biopsies from patients with inflammatory bowel disease (n = 17) and rheumatoid arthritis (n = 2) with new-onset inflammatory skin lesions during anti-TNF-α-therapy. RESULTS Although most biopsies showed a psoriasiform and/or spongiotic (eczematous) histopathological architecture, these lesions were inconsistent with either psoriasis or eczema on a molecular level using an established chemokine (C-C motif) ligand 27/inducible nitric oxide synthase classifier. Despite some differences in immune skewing depending on the specific histopathological reaction pattern, all anti-TNF-α-induced lesions showed strong interferon (IFN)-γ activation, at higher levels than in psoriasis or eczema. IFN-γ was most likely produced by CD3/CD4/Tbet-positive T helper 1 lymphocytes. CONCLUSIONS New-onset anti-TNF-α-induced eruptions previously classified as psoriasis or spongiotic dermatitis (eczema) exhibit a molecular profile that is different from either of these disorders.

Abstract
BACKGROUND Adaptive desensitization still remains the only causative therapy for acetylsalicylic acid (ASA) hypersensitivity and is carried out nearly worldwide. To date there are hardly any data available on disease development under current desensitization therapy and longitudinal data in particular are missing. STUDY DESIGN Out of a large collective of patients with proven hypersensitivity to ASA, 194 patients with initiated desensitization treatment were observed for periods up to 5 years (average 32 months). RESULTS Patients with immediate reactions to systemic challenge tests revealed a response rate of 77% after 12 months of therapy. In this period 12% reached complete remission, 38% showed a clear reduction in symptoms, 32% reached partial remission, 13% remained unchanged and 5% suffered from disease progression. CONCLUSION Adaptive desensitization therapy for hypersensitivity to ASA has been shown to be an effective causative therapy and chronic hyperplastic sinusitis as well as bronchial asthma could be improved. For the determination of maintenance dosages and required time periods more data are needed.

Abstract
Mutations in the GJB2 gene are known to represent the commonest cause of hereditary and congenital hearing loss. In this study, a complete sequencing of the GJB2 gene in a cohort of 506 patients from a single, large cochlear implant program in Europe was performed. Audiological testing for those patients who could actively participate was performed using pure tone audiometry (PTA). Those unable to undergo PTA were measured using click-auditory brainstem response (ABR). Data analysis was performed to determine genotype-phenotype correlations of the mutational status vs. audiological profiles and vs. age at the time of presentation. An overall prevalence of biallelic mutations of 13.4% was found for the total collective. When subsets of younger patients were examined, the prevalence increased to 27% of those up to age 18 and 35% of those up to age 5 at the time of testing, respectively. This increase was found to be highly significant (p < 0.001). Analysis of the mean PTA thresholds revealed a strong correlation between allele combination status and mean PTA (p = 0.021). The prevalence of simple heterozygotes was found to be approximately 10.1%, which is around 3.3 times the value expected in the general population. As GJB2 follows a recessive pattern of inheritance, the question arises as to why such a large fraction of simple heterozygotes was observed among the hearing impaired patients included in this study.

Abstract
Tissue from endometrial diagnostic curettage material may show small clumps of stromal cells, which are pushed together (stromal collapse) and present a picture of glandular and stromal breakdown. This can be misinterpreted as small cell structured carcinoma, possibly of neuroendocrine or basal cell origin. Immunohistochemical investigations (e.g. estrogen receptor, epithelial and neuroendocrine markers and proliferation markers) are helpful in identifying the correct differential diagnosis.

Abstract
BACKGROUND High-dose corticosteroids are currently recommended for idiopathic sudden sensorineural hearing loss (ISSNHL) treatment. Intratympanic injections (ITI) are of growing importance, especially in cases of therapy resistance. The selection of patients for this procedure in SSNHL has not been adequately examined so far. STUDY DESIGN A total of 77 patients with ISSNHL after ineffective systemic pretreatment underwent intratympanic administration of dexamethasone and hyaluronic acid. Improvement after treatment was determined by pure tone audiometry for both ears before and of the treated ear after ITI. RESULTS In this study 34 female and 43 male patients with mean age of 57 years showed a pre-ITI hearing loss of 35 dB in the lower frequencies and 69 dB in the higher frequencies. The mean hearing gain was 10 dB and the response rate was 62%. Absolute hearing gain revealed significant improvements at 500 Hz, 1 kHz and 2 kHz. Under inclusion of contralateral thresholds there were hardly any differences up to 4 kHz. In a detailed analysis of responders moderate improvements could be observed even in higher frequencies. Overall, no relevant adverse events occurred. CONCLUSION Treatment of ISSNHL resistant to systemic regimens by ITI of steroids provides an option that offers additional prospects of auditory improvement for affected patients. The presented results indicate that these modalities are also valid for patients with pancochlear ISSNHL.

Abstract
This article presents the case of a patient with a submandibular cervical tumor initially suspected to be a large lymph node or glomus tumor. However, the diagnostic workup prior to taking a biopsy sample revealed an extracranial aneurysm of the internal carotid artery. In order to prevent a permanent neurologic deficit arising from thromboembolism, the aneurysm was excluded by resection and arterial continuity was restored. Extracranial aneurysms of the internal carotid artery are rare, but serious differential diagnoses of cervical nodes. It is of paramount importance that this differential diagnosis be considered before initiating invasive diagnostics of these tumors.

Abstract
Deep-seated lipomatous tumors of the peripheral soft tissue of the extremities are uncommon. The majority represent atypical lipomatous tumors or well-differentiated liposarcomas. On rare occasions benign adipocytic tumors, such as hibernoma may present as huge, deep-lying subfascial masses. As a consequence of the deep location and usually heterogeneous signal intensities in imaging, they are particularly at risk to be misinterpreted as liposarcomas on clinical grounds. Furthermore, the rarity and thus limited familiarity with the morphological appearance and spectrum still represent a pitfall for the histopathological assessment.

Abstract
INTRODUCTION Hamartomas are benign tumor-like lesions resulting from incorrectly differentiated germplasm and can manifest in different organ systems. In the nasal cavity and the sinuses these lesions are rare. Only few data on etiology, epidemiology and clinical significance of these tumors exist to date. MATERIALS AND METHODS In a retrospective study, material from patients treated in the Clinic for Otorhinolaryngology, Head and Neck Surgery of the Ulm Military Hospital was screened on the incidence and clinical courses of respiratory epithelial adenomatoid hamartomas (REAH) of the nose and nasal cavity. Furthermore, for cases of REAH, formalin-fixated paraffin-embedded tissue samples were re-evaluated and examined for human papillomavirus (HPV) DNA by PCR. RESULTS Tissue samples from 8145 surgical interventions on the nose and nasal sinuses from 2003 to 2012 were included. A total of 22 patients (3 female, 19 male; median age 57.5 years) diagnosed with REAH could be identified. Major complaints were nasal blockage (91 %), sinusitis (82 %), rhinorrhea (36 %) and cephalgia (23 %). Nasal endoscopy showed polyps in 68 % of patients. Native nasal sinus CT scans revealed no indications of REAH. Intraoperatively, hamartomas were found in 12 patients originating from the ethmoid bone, in 8 from the middle meatus or infundibulum and in 2 from the olfactory cleft. Macroscopic and histological examination showed compact lesions sized between 4 and 25 mm in the largest diameter containing homologous tissue, without signs of dysplasia or malignancy. HPV DNA was not identified in any case. CONCLUSION REAH of the nasal cavity and sinuses are rare benign local tissue lesions, usually without any autonomous proliferation. Clinical signs and findings correspond to those in polypoid pansinusitis. Only with single-sided or olfactory cleft location might CT scans provide indication of a tumorous lesion. For differentiation from true neoplasms, surgical resection and histopathological clarification is indicated. On the basis of current knowledge, complete surgical resection is adequate therapy.

Abstract
OBJECTIVE Implantable hearing aids have become a valid option for the therapy of various forms of hearing loss. The Codacs™ Direct Acoustic Cochlear Implant System is the first vibratory implant available for patients with severe to profound mixed hearing loss (MHL). By directly coupling sound energy into the perilymph, a very high maximum power output (MPO) is achieved over a broad frequency range. Via a conventional stapedotomy, the vibratory energy of the electromagnetic actuator is transferred directly to the perilymph through the oval window. PATIENTS AND METHODS This article describes the technical principle, basic surgical aspects and audiological outcomes of two clinical studies. Additional coupling procedures and extensions to the spectrum of indications are also discussed. Surgically, the two-component system can either be implanted via a purely transmastoid approach with posterior tympanotomy, or additionally via transmeatal access to the stapes footplate. Pre- and postoperative audiological results of patients wearing conventional hearing aids and with severe to profound MHL, who were implanted with the Codacs™ system at the Medical University Hannover, were compared. RESULTS Significant improvements over conventional hearing aids could be achieved with initial bone conduction thresholds between 44 and 63 dB HL (Ø 54 dB HL) and an air-bone gap between 19 and 51 dB HL (Ø 34 dB HL) in patients with MHL caused by advanced otosclerosis or tympanosclerosis and an intact posterior wall of the auditory canal. The mean functional gain was 50 ± 9 dB (0.5-4 kHz) and the monosyllabic word score was 85% at 65 dB presentation level compared to conventional hearingaids with 25%. Speech intelligibility in noise (S0N0) improved by 7.1 to Ø 0.3 dB SNR with Codacs™. The mean bone conduction threshold remained unchanged or showed a minimal increase in the low-frequency range. CONCLUSION The CODACS system provides an effective new treatment for patients with severe to profound MHL for the first time.

Abstract
95Mo and 97Mo Fourier transform NMR studies of several alkali molybdate solutions in H2O and D2O are reported. The Larmor frequency of the molybdenum nuclides is remarkably dependent on the solute and the solvent.
In potassium molybdate the chemical shifts of 39K were observed. The ratio of the Larmor frequencies of 95Mo and 39K was measured with high accuracy in a 2.6 molal solution of K2MoO4 in H2O. From this value a nuclear magnetic moment of 95Mo and 97Mo in the molybdate ion was derived using the concentration dependencies of the Larmor frequencies of 39K and 95Mo and the ratio of the Larmor frequencies of 97Mo and 95Mo.
In solid Ag2MoO4 and metallic molybdenum the 95Mo and 97Mo NMR signals were detected; line widths and shifts are given.

Abstract
Photozellen mit Sekundär-Elektronenvervielfachung (sog. Multiplier) wurden in den letzten Jahren zunehmend für die photometrische Messung kleiner Strahlungsintensitäten herangezogen. Bei den zu diesem Zweck entwickelten Methoden wird fast immer vorausgesetzt, daß Beleuchtungsstärke und vom Vervielfacher gelieferte Stromstärke einander innerhalb der verlangten Meßgenauigkeit von etwa 1% proportional sind. In Analogie zu früheren Messungen an Photozellen wird gezeigt, daß diese für den Primär-Photoeffekt vorauszusetzende Proportionalität bei technischen Photozellen und Vervielfachern keineswegs immer vorhanden ist, sondern daß Abweichungen auftreten können, die diese Genauigkeit um mehr als eine Zehnerpotenz überschreiten. Photometrische Präzisionsmessungen sind mit Photozellen wie mit Vervielfachern nur möglich, wenn man echte Nullmethoden mit optischer Kompensation von Intensitätsänderungen benutzt.

Abstract
BACKGROUND AND OBJECTIVE A case-control study was conducted to investigate occupational and other risk factors for squamous cell carcinoma of the oral cavity, the pharynx and the larynx. The study included 209 male cancer patients and 110 male control persons without known malignant disease, matched for age, alcohol consumption and tobacco consumption. PATIENTS/METHODS Cases and controls were interviewed using a standardized questionnaire which has been used before in the Heidelberg case-control studies. RESULTS AND CONCLUSIONS The educational level in the cancer group was significantly lower (p < 0.001). 17.2% of the cancer patients and 7.3% of the control persons had not completed their professional training. The percentage of so-called "blue-collar workers" was significantly higher in the cancer group (20.9% vs. 7.3%; p < 0.002). An increased cancer risk was observed for workers exposed to asbestos (OR = 8.7; p = 0.004) and cement dust (OR = 12.9; p < 0.001). A frequent consumption of various vegetable food like carrots (OR = 0.17; p < 0.001), fruits (OR = 0.38; p < 0.001) or green salad (OR = 0.25; p < 0.001) was associated with a significant reduction of cancer risk.

Abstract
There is increasing evidence worldwide that human papillomavirus is a major risk factor for head and neck cancer. Only few studies on this association have been performed in Germany to date. For the purposes of the present study, tumor specimens from 223 patients with squamous cell cancer of the oral cavity, oropharynx, hypopharynx and larynx were analyzed for HPV DNA and p16INK4a expression. The prevalence of HPV genotype 16 (HPV16) DNA in the study population was 17.5%. Further high-risk HPV types were not detected. All HPV16-positive tumors showed intense p16INK4a expression. HPV16 prevalence was highest in tonsillar carcinoma (37.5%) and lowest in laryngeal cancer (2.8%). We observed a significantly higher incidence of cervical lymph node metastases in patients with HPV16-positive tonsillar carcinoma in comparison to HPV-negative tumors (p < 0.016). Tobacco and/or alcohol consumption was significantly lower in patients with HPV-positive tumors (p < 0.0001).

Abstract
BACKGROUND Unlike malignant primary central nervous system (CNS) tumours outcome data on non-malignant CNS tumours are scarce. For patients diagnosed from 1996 to 2002 5-year relative survival of only 85.0% has been reported. We investigated this rate in a contemporary patient cohort to update information on survival. METHODS We followed a cohort of 3983 cases within the Austrian Brain Tumour Registry. All patients were newly diagnosed from 2005 to 2010 with a histologically confirmed non-malignant CNS tumour. Vital status, cause of death, and population life tables were obtained by 31 December 2011 to calculate relative survival. RESULTS Overall 5-year relative survival was 96.1% (95% CI 95.1-97.1%), being significantly lower in tumours of borderline (90.2%, 87.2-92.7%) than benign behaviour (97.4%, 96.3-98.3%). Benign tumour survival ranged from 86.8 for neurofibroma to 99.7% for Schwannoma; for borderline tumours survival rates varied from 83.2 for haemangiopericytoma to 98.4% for myxopapillary ependymoma. Cause of death was directly attributed to the CNS tumour in 39.6%, followed by other cancer (20.4%) and cardiovascular disease (15.8%). CONCLUSION The overall excess mortality in patients with non-malignant CNS tumours is 5.5%, indicating a significant improvement in survival over the last decade. Still, the remaining adverse impact on survival underpins the importance of systematic registration of these tumours.

Abstract
Hearing loss is the most frequently occurring congenital sensory defect in humans. It is believed that between one and five of every 1000 children born suffers from hearing loss of at least 40 dB. The economic consequences of deafness are staggering and affect not only the individual patient but also society as a whole. A genetic cause is suspected in 50 %-70 % of cases of congenital hearing loss. To date over 130 loci have been associated with genetic hearing loss, with some loci containing more than one gene and others containing as yet unidentified genes. The present article is intended to provide some insight into the complex background issues involved and offer guidance on appropriate decision-making with regard to genetic testing in affected patients. Part 1 is concerned with non-syndromic hearing loss, while part 2 deals with syndromic hearing loss.

Abstract
Allergen-specific immunotherapy for grass pollen allergy has been reported to be effective in up to 85% of patients. Sensitisation to profilin and calcium-binding protein (CBP) can possibly influence treatment results and may thus be a reason for treatment failures. During a study period of 3 years, the distribution patterns of antibodies to marker allergens were continuously investigated in all blood serum samples with a level of immunoglobulin E antibodies to timothy and birch pollen higher than 0.7 kUA/l (n = 556). Sensitisation to timothy grass pollen alone was found in 33% of the cases, to birch pollen alone in 19%, and to both in 48%. The group of polysensitised patients showed an inhomogenous distribution of antibodies to marker allergens. IgE against minor allergens was detected in 40%. Sensitisation to major allergens, especially to the major birch allergen, was not present in 13% of the polysensitised patients. Of the patients who were sensitised to minor allergens, 82% were sensitised to profilin, 11% to CBP, and 8% to both profilin and CBP. Profilin and CBP frequently cause polysensitisations to pollen. The data obtained justify the measurement of serum levels of antibodies to marker allergens in patients who are sensitised to more than one group of allergens.

Abstract
BACKGROUND Extracapsular spread of cervical lymph nodes deteriorates the prognosis of patients with head and neck squamous cell carcinoma. Postoperative radiochemotherapy is superior to postoperative radiotherapy alone in patients with histologically proven extracapsular spread. If extracapsular spread can be detected preoperatively, patients may favor primary radiochemotherapy instead of primary surgery plus postoperative radiochemotherapy. METHODS Computed tomography (CT) scans of nodal positive head and neck squamous cell carcinoma patients treated between 2008 and 2010 with comprehensive neck dissection as part of first line surgical treatment were retrospectively scanned for extracapsular spread by two blinded radiologists. If a positive lymph node was identified by the pathologist, CT scans were assessed for extracapsular spread retrospectively. CT criteria for Extracapsular spread were apparent fat and soft tissue infiltration or infiltration of sternocleidomastoid muscle, internal jugular vein or carotid artery. Radiologic judgment was compared with histological evidence of extracapsular spread and specificity and sensitivity of CT detection was calculated. RESULTS Forty-nine patients with histologically proven positive lymph nodes (pN+) were included. Extracapsular spread was histologically proven in 17 cases; the number of all affected lymph nodes was not listed. Radiologist 1 found extracapsular spread in CT scans of 15/49 patients and radiologist 2 in 16/49 patients (Cohen's kappa=0.86; p<0.01). Sensitivity of radiologic extracapsular spread detection was 73% (95% confidential index (CI): 44.0-89.7%) and specificity 91% (75.0-98.0%). CONCLUSION Extracapsular spread depicted on computed tomography using strict criteria has high specificity.
