Background: The glucocorticoid receptor gene (NR3C1) encodes the receptor to which cortisol and other glucocorticoids bind. Steroids in either oral, intratympanic, or intravascular forms are the treatment of choice for sudden sensorineural hearing loss (SSNHL), but the outcome varies. The outcomes of SSNHL have been investigated for related factors, including age, initial hearing loss severity and pattern, vertigo, genetic variations, and the time between onset and treatment.

Methods: This was a retrospective study performed in an academic medical center. Patients who received tympanoplasty with mastoidectomy for COM with and without cholesteatoma were included.
Background: Many factors are thought to be associated with the development of cholesteatoma, while the mechanisms of its formation remain unclear. This study aimed to identify the potential mechanisms of the proliferation and growth of cholesteatoma by analysis of the differential expressions of proteins in cholesteatoma and retroauricular skin tissue collected from the same patients.
Methods: The present study is a retrospective study performed in an academic medical center.
Objectives: Quantum molecular resonance (QMR) devices have been applied as energy-based devices in many head and neck surgeries; however, research on their use in thyroid surgery is lacking. This study aimed to investigate the safety parameters of QMR devices during thyroidectomy when dissection was adjacent to the recurrent laryngeal nerve (RLN).
Methods: This study included eight piglets with 16 RLNs, and real-time electromyography (EMG) signals were obtained from continuous intraoperative neuromonitoring (C-IONM).
Background: Sudden sensorineural hearing loss (SSNHL) is a disease with an unknown etiology; damage to the auditory nerve from inflammation due to viral infection or vascular incidents has been implicated. According to several studies, cytokines, including interleukins, are associated with SSNHL in terms of serum expression and genetic polymorphisms. Interleukin-1 (IL-1) plays a key role in inflammation and may be associated with SSNHL.

Background: Age-related hearing impairment (ARHI) is a major disability among the elderly population. Heat shock proteins (HSPs) were found to be associated with ARHI in animal studies. The aim of this study was to analyze the associations of single nucleotide polymorphisms (SNPs) of HSP genes with ARHI in an elderly population in Taiwan.

Objective: Delayed facial palsy is a complication of otologic surgery. Tympanoplasty is commonly employed in chronic otitis media. We compared the incidence and characteristics of delayed facial palsy and hearing restoration between endoscopic and microscopic tympanoplasty for the treatment of simple chronic otitis media.

Background: The treatment of middle ear cholesteatoma has been challenging due to an insufficient understanding of the underlying disease mechanism.
Background: Age-related hearing impairment (ARHI) is a major disability among the elder population. Chronic inflammation is an important factor in the development of ARHI. Interleukin-1 (IL-1) plays a key role in inflammation and may be associated with ARHI.

The aim of this study was to explore the relationship between NAFLD fibrosis score (NFS) and the estimated glomerular filtration rate (eGFR), and identify possible risk factors related to the NFS among Taiwanese subjects.
Methods: Subjects were enrolled from the database of the Department of Preventive Medicine of Kaohsiung Municipal Hsiao-Kang Hospital.
Objectives: Age-related hearing impairment (ARHI) is a major disability among the elderly. This study aimed to analyze the association of single nucleotide polymorphisms (SNPs) of metabotropic glutamate receptor 7 (GRM7) gene with ARHI in an elderly population in Taiwan.
Materials And Methods: This was a community-based study performed in a metropolitan hospital.
Background: The aim of this study was to ascertain the relationships of blood pressure, fasting sugar level, triglyceride (TG) level, uric acid level, and body mass index (BMI) with proteinuria and the estimated glomerular filtration rate (eGFR) in a population from southern Taiwan.
Methods: The 20,900 subjects enrolled in this study had undergone a free adult health examination under the National Health Insurance scheme between September 2005 and June 2011. Factors such as blood pressure, blood sugar, TG, uric acid and BMI were examined in terms of their relationships with the eGFR (calculated according to the Taiwanese Modification of Diet in Renal Disease (Taiwanese-MDRD)) and proteinuria.
The glutathione peroxidase 3 gene (GPX3) is reported to be a risk factor for arterial ischaemic stroke and cerebral venous thrombosis. GPX3 may be one of the aetiologies of sudden sensorineural hearing loss (SSNHL), which might be attributed to the genetic effect of GPX3 by influence reactive oxygen species (ROS). Unbalanced ROS have been associated with susceptibility to SSNHL.

The phosphodiesterase 4D (PDE4D) gene has been reported as a risk gene for ischemic stroke. The vascular factors are between the hypothesized etiologies of sudden sensorineural hearing loss (SSNHL), and this genetic effect might be attributed for its role in SSNHL. We hypothesized that genetic variants of the PDE4D gene are associated with susceptibility to SSNHL.
