Introduction: Stimulation of the nonauditory nervous systems via the trigeminal nerve pathways can be a promising intervention for patients with tinnitus refractory to medical, conservative, and other treatment options. Therapy of the mandibular division of the trigeminal nerve through the auriculotemporal nerve has been reported as useful for patients with tinnitus.

Objectives: The objective of our study was to study the long-term effects of pulsed radiofrequency of the auriculotemporal nerve in a large group of tinnitus sufferers and to find predictors for a prosperous result.

Tinnitus Background: Vagal nerve stimulation is a promising therapy for tinnitus. Pulsed radiofrequency is a minimally invasive neuromodulator technique that could be applied repeatedly without damage to neural tissue. In this case-study we document the use of pulsed radiofrequency of the vagal nerve as a successful therapy without harm for patients with tinnitus.

Introduction: Tinnitus distress is associated with the perceived loudness of the tinnitus.

Objectives: To evaluate the psychosocial problems in tinnitus patients and to explore any relation with the tinnitus loudness.

Design: From all patients who were treated in our clinic from January 2017 to September 2019 for their tinnitus, patients chart and a questionnaire with the psychosocial variables were studied retrospectively.

Introduction: The second cervical nerve ganglion bar appears to be beneficial in patients with treatment safe tinnitus. As far as anyone is concerned, the viability of this methodology in patients with tinnitus has never been evaluated.

Objectives: The point of this investigation was to decide the adequacy of beat radiofrequency of C2 dorsal root ganglion for treating patients with tinnitus, and all the more explicitly, to survey the parameters related with a long haul advantage so as to improve understanding determination.

Introduction: The high prevalence together with the serious impact of sleep disturbances assessed in tinnitus patients urge the need for effective therapy that could improve patients' sleep quality.

Objectives: The purpose of this study was to assess the reported prevalence and severity of sleep disturbance in chronic tinnitus patients and to extract possible tinnitus specific factors that increase the risk of developing sleep disturbances.

Design: Subjects were 165 consecutive patients who came to our clinic from January 2017 to January 2019 for consultations on their tinnitus that persisted for one month or longer.

Introduction: Patients with tinnitus without an identifiable cause may have temporomandibular joint dysfunction and can be treated by an intra-articular injection of steroids.

Objectives: The aim of this study was to determine the efficacy of temporomandibular steroids for treating patients with tinnitus, and more specifically, to assess the parameters associated with a long-term benefit in order to improve patient selection.

Design: Subjects were 70 consecutive patients who came to our clinic from October 2016 to October 2018 for consultations on their tinnitus that persisted for one month or longer and were treated with an intra-articular injection of the temporomandibular joint with steroids.

Genetic studies have identified Protocadherin-1 (PCDH1) and Mothers against decapentaplegic homolog-3 (SMAD3) as susceptibility genes for asthma. PCDH1 is expressed in bronchial epithelial cells and has been found to interact with SMAD3 in yeast two-hybrid (Y2H) overexpression assays. Here, we test whether PCDH1 and SMAD3 interact at endogenous protein levels in bronchial epithelial cells and evaluate the consequences thereof for transforming growth factor-β1 (TGF-β1)-induced gene transcription.

Protocadherin-1 (PCDH1) is a novel susceptibility gene for airway hyperresponsiveness, first identified in families exposed to cigarette smoke and is expressed in bronchial epithelial cells. Here, we asked how mouse Pcdh1 expression is regulated in lung structural cells in vivo under physiological conditions, and in both short-term cigarette smoke exposure models characterized by airway inflammation and hyperresponsiveness and chronic cigarette smoke exposure models. Pcdh1 gene-structure was investigated by Rapid Amplification of cDNA Ends.

Tinnitus represents one of the most common and distressing otologic problems, and it causes various somatic and psychological disorders that interfere with the quality of life. Treatments for tinnitus include pharmacotherapy, cognitive and behavioral therapy, sound therapy, music therapy, tinnitus retraining therapy, massage and stretching, and electrical suppression. In this case report we present a potential treatment, namely pulsed radiofrequency to the ganglion C2.

Protocadherin-1 (PCDH1) is a novel susceptibility gene for asthma that is expressed in airway epithelium. We aimed to characterize PCDH1 mRNA transcripts and protein expression in primary bronchial epithelial cells and to determine regulation of PCDH1 during mucociliary differentiation. Total RNA and protein were isolated from human primary bronchial epithelial cells.

Background:   Eczema and asthma share a common genetic background and show linkage to chromosome 5q31-33. Protocadherin-1 (PCDH1) is located in this region and was identified as a susceptibility gene for bronchial hyper-responsiveness (BHR), a hallmark of asthma. PCDH1 encodes an adhesion molecule, expressed in airway and skin epithelium.
