BACKGROUND/AIMS: According to recent studies, central auditory impairments are closely related to neurodegenerative diseases. However, the mechanism of central presbycusis remains unclear. Ubiquitin C-terminal hydrolase L1 (UCHL1) is important in maintaining proteasomal activity; however, the detailed mechanism has not yet been fully elucidated. This study aims to investigate the molecular alterations involved in UCHL1 regulation during auditory cortex aging. METHODS: D-Galactose (D-gal) induces oxidative stress and senescence in the auditory cortex, as reported in our previous studies...

BACKGROUND: A postintubation tracheoesophageal fistula is a rare complication of a tracheotomy. Surgical repair is the only viable option for these patients, but the repair techniques presented in the literature vary. METHODS: We used a modified tracheal transaction approach to repair 5 cases of nonmalignant tracheoesophageal fistulas. The procedure was performed with a low cervical collar incision, and the trachea was transected directly. All the procedures were only carried out in the surgical field created by tracheostomy and paratracheal and esophageal dissection was no longer necessary...

PURPOSE: Benign mesenchymal sinonasal neoplasms (BMSN) are rare and histologically heterogeneous. Differential diagnosis, appropriate management, and outcome are still a matter of debate. The aim of this study is to provide evidence for further refinement of assessment and treatment in the future. PROCEDURES: We retrospectively reviewed data on 93 patients with neuroradiologically verified BMSN treated at our university reference center during the past 22 years...

Transmembrane C-X-C chemokine receptor 4 (CXCR4) and its ligand C-X-C motif chemokine 12 (CXCL12) came into focus in many solid cancers, allowing a more fundamental diagnostic and therapeutic approach by modulating the immune response against cancer cells. CXCR4 and CXCL12 mediate cell proliferation, migration, and metastatic outgrowth in head and neck squamous cell carcinoma (HNSCC) and are strongly associated with cancer recurrence and patient survival. Despite recent advances in molecular imaging and cancer therapy in lymphoma using CXCL12 analogues, clinical trials evaluating the diagnostic and therapeutic impact on HNSCC are missing...

Obstructive sleep apnea is one of the most common diseases in Western industrialized countries. A variety of conservative and surgical treatment options are available for its treatment. In recent years, selective upper airway stimulation (sUAS) has been shown to be effective and safe. Different biomarkers have been investigated as predictive clinical success factors in a number of clinical trials. Age does not matter in sUAS, as compared to its predictive role in other therapies. Weight seems to play a limited role, depending on drug-induced sleep endoscopy to rule out a complete concentric collapse with an increased body mass index...

Chronic rhinosinusitis is an umbrella term for several phenotypes and mechanistically distinct inflammatory diseases of the nose and the paranasal sinuses affecting around 11% of the population in Europe and the USA. Approximately 20% of the patients present with uncontrolled disease despite adequate treatment, and revision surgery is common. While a clinical characterization alone does not improve treatment results, novel but expensive biologics have increasingly become available, but they require a better understanding of the mechanism...

In Europe, ultrasound (US) is the diagnostic gold standard for the visualisation of parotid gland disorders. While high-resolution B-mode US reliably visualises focal lesions, its diagnostic capacity to distinguish tumour entities or to characterise diffuse lesions remains poor. Strain elastography (SE) and shear wave elastography (SWE) are novel imaging techniques that provide additional information about tissue elasticity. SE analyses the strain or displacement in response to force or compression and, therefore, shows the relative tissue elasticity within a selected region of interest (ROI)...

The immune system functions to defend the organism against infectious microorganisms but also against transformed cells. This key role of the immune system, in particular cancer-specific T cells, in eliminating cancer cells is compromised by various immune escape strategies employed by cancer cells and the cancer microenvironment. Here, we review the current knowledge about the immune escape mechanisms of cancer and the attempts to reconstitute cancer-specific immunity by using checkpoint inhibitors in head and neck squamous cell carcinoma...

BACKGROUND: Angiotensin-converting enzyme inhibitor-induced angioedema (ACEi-AE) is the most frequent drug-induced angioedema. The aim of this study was to evaluate potential biomarkers for the detection of the risk to develop an ACEi-AE. METHODS: Adult patients who started antihypertensive treatment with ramipril were included and followed up for 4-6 weeks. At baseline, 3 days, and 4-6 weeks after onset of therapy, blood samples were obtained. RESULTS: Twenty-four patients could be enrolled...

In oncology, biomarkers that describe the characteristics of a malignancy on different levels (clinical, histological, molecular) and the patient's outcome and treatment response are increasingly integrated into the clinical routine. Extensive screening tools, "omics," offer incredible opportunities and vast amounts of data. During the last years, the field of "omics" gained a new promising partner, the "radiomics." Based on radiological imaging, multiple features can be extracted and linked to clinical, genomic, and histopathological data from other sources...

A review of more than 20 years of experience with vibratory stimulation in vestibular diseases is given. Vibrations in a frequency frame of 30-60 Hz are applied on the mastoid during 20 s. Eye movements are recorded by video-oculography to detect a vibration-induced nystagmus (VIN). A VIN occurs in cases of a side difference between the peripheral vestibular receptors beating to the side of better excitability. In patients with central lesions, a VIN does not appear generally, only exceptionally if the lesion is located laterally in the brain stem...

In medicine, biomarkers are a metric for disease state. More generally, a biomarker is anything that can be used as an indicator for a particular disease state or any physiological state of an organism. Here, we introduce functional and molecular biomarkers that are useful for categorizing defined subtypes of hearing disorder, which can help to selectively trace a particular dysfunction of the inner ear and the auditory pathway to disease.

Curative treatment of head and neck squamous cell carcinoma includes surgery and/or (chemo)radiation, whereas in the palliative setting, chemotherapy and/or immunotherapy represent(s) the standard approach. With regard to quality control, methods for determining treatment response are sorely needed. For surgical therapy, histopathology is the standard quality control. Established criteria for high-risk patients include resection margins of the primary tumor and extracapsular extension of lymph node metastases...

Hans P Zenner
Molecular personalized medicine tries to generate individual predictive biomarkers to assist doctors in their decision making. These are thought to improve the efficacy and lower the toxicity of a treatment. The molecular basis of the desired high-precision prediction is modern "omex" technologies providing high-throughput bioanalytical methods. These include genomics and epigenomics, transcriptomics, proteomics, metabolomics, microbiomics, imaging, and functional analyses. In most cases, producing big data also requires a complex biomathematical analysis...

Clinical diagnoses of allergic airway disease need confirmation of a relevant sensitization to allergens. Serum-based component-resolved diagnosis has become increasingly popular and allows the precise assessment of specific IgE to molecular allergens. Molecular allergen diagnosis has improved our understanding of disease phenotypes in allergic patients, including cross-reactive patterns and food allergy. Beyond sensitization profiles, characterization of the (endo-)type and severity of a local allergic disease is useful for targeted therapy with biologics in advanced allergic airway disease...

Salivary glands are frequent sites of manifestations of autoimmune disorders in the head and neck. Sjögren syndrome, sarcoidosis, granulomatosis with polyangiitis, and IgG4-related sialadenitis represent the most important autoimmune salivary gland disorders. Due to the lack of specific symptoms, diagnosis of these conditions remains a challenge. Diagnosis is usually based on classification criteria involving clinical tests, histopathological evaluation, and serological examinations. Depending on the disease, biomarkers are of different value and have to be interpreted carefully...

BACKGROUND/OBJECTIVE: In multilevel surgery for obstructive sleep apnea (OSA), the contribution of distinct operative steps is still unclear. The aim of the present study is to retrospectively compare different combinations of multilevel surgeries in order to estimate the contribution of hyoid and tonsillar procedures to the outcome. METHODS: A total of 45 patients were selected in a retrospectively matched case-control study from a database of patients who underwent surgery for OSA at our institution: group A (n = 15) had hyoid suspension, tonsillectomy, and radiofrequency-assisted uvulopalatoplasty (RAUP); group B (n = 15) had hyoid pharyngoplasty with resection of the hyoid body and preepiglottic fat tissue, tonsillectomy, and RAUP; and group C (n = 15) had hyoid suspension and RAUP but no tonsillectomy, because the tonsils had already been removed...

BACKGROUND AND PURPOSE: Human papilloma virus-related oropharyngeal carcinoma (HPV+ OPC) is a unique entity compared to HPV-unrelated (HPV-) OPC. Previous studies were inconclusive regarding the differences between HPV+ and HPV- OPCs on diffusion-weighted imaging (DWI). This study sought to determine if there is an association between HPV status and apparent diffusion coefficient (ADC) values as an imaging biomarker in OPCs. MATERIALS AND METHODS: OPC patients with pretreatment MRI including DWI were retrospectively reviewed and analyzed as a blinded, controlled cohort...
