Wireless mobile ultrasonography-assisted parotid duct stone removal.

Ultrasonography is highly sensitive for the diagnosis of sialoliths. Recently, wireless mobile ultrasonography was developed. We describe the case of a 49-year-old man who presented with painful postprandial left cheek swelling.

SERPINB2 is a novel indicator of stem cell toxicity.

The toxicological evaluation of potential drug candidates is very important in the preclinical phase of drug development. Toxic materials may cause serious decline in stem cell function and loss of stemness. Indeed, we found that toxic exposure more profoundly suppressed the growth of stem cells than terminally differentiated fibroblasts.

The Effect of Human Adipose Tissue-Derived Mesenchymal Stem Cells in Rat's Subglottic Stenosis Model.

Objective: Subglottic stenosis remains a clinical challenge. The aim of this study was to evaluate the effect of human adipose tissue-derived mesenchymal stem cells (hAMSCs) in rat model of subglottic stenosis.

Subjects And Methods: Ninety-six 13-week-old male rats were enrolled in this study.

Is Surgical Navigation Useful for Treating Zygomatic Arch Fractures?

Objective: To report the case of a 58-year-old man with a zygomatic arch fracture, which was well localized and reduced using a surgical navigation system.

Methods: In this clinical report, the authors suggest intraoperative surgical navigation systems are useful diagnostically and for localizing sites of zygomatic arch fractures.

Results: The patient underwent successful closed reduction of zygomatic arch fractures using a surgical navigation system.

Age-Related Changes in Nuclear Factor Erythroid 2-Related Factor 2 and Reactive Oxygen Species and Mitochondrial Structure in the Tongues of Fischer 344 Rats.

Objectives: Previously the authors reported age-related changes in the activities of anti-oxidative enzyme activities and protein expressions in the tongues of rats. Because more information is required about relations between aging and oxidative stress and anti-oxidative enzyme efficiency, the authors investigated differences between the expression of master regulator of anti-oxidative enzymes (nuclear factor erythroid 2-related factor 2 [Nrf2]), levels of reactive oxygen species (ROS), and mitochondrial structures in the tongues of young and aged Fischer 344 rats.

Methods: Age-dependent changes in Nrf2 protein and ROS were determined by Western blotting and using chemical kits, respectively.

Efficacy of Posterior Canal Wall Reconstruction Using Autologous Auricular Cartilage and Bone Pâté in Chronic Otitis Media with Cholesteatoma.

Objective: This study was designed to investigate the long-term results using the technique of canal wall up mastoidectomy and reconstruction of the posterior canal wall using bone pâté and auricular cartilage in the treatment of chronic otitis media with cholesteatoma.

Materials And Methods: A retrospective review was performed on 42 patients who underwent canal wall up mastoidectomy and posterior canal wall reconstruction at a single institution between November 2005 and November 2012.

Results: Of the 42 patients, postoperative tympanic membranes were normal in 38 (90.

Failed septal extension graft in a patient with a history of radiotherapy.

Background: This report describes the authors' experience of "melting" septal cartilage after placement of a septal extension graft in a nasopharyngeal cancer patient that had been previously undergone radiation therapy, and provides a review of the literature.

Methods: Electronic medical records were used to obtain details of the patient's clinical history.

Results: A 32-year-old woman, who had previously undergone radiotherapy for nasopharyngeal cancer, visited our department to for rhinoplasty.

Health-Related Quality of Life in Korean Adults with Hearing Impairment: The Korea National Health and Nutrition Examination Survey 2010 to 2012.

Background: As the global population ages, disabling hearing impairment (HI) have been increased rapidly. The impact of HI on health-related quality of life (HRQoL) is of great importance to aid the development of strategic plans and to guide therapeutic interventions.

Purpose: To evaluate HRQoL in Korean adults with different degrees of HI using EuroQol five-dimensional (EQ-5D) and EQ-visual analogue scale (VAS), the preference-based generic measures of HRQoL.

Age-Related Changes in Antioxidative Enzyme Capacity in Tongue of Fischer 344 Rats.

Objectives: Antioxidative enzyme efficiency changes in some organs with age. However, no study has been conducted on age-related antioxidant enzyme changes in tongue. In the present study, the authors investigated the activities of four antioxidative enzymes and their protein expressions in the tongues of young and old Fischer 344 rats.

A case of pediatric ectopic thyroid in lateral lymph nodes.

On average, ectopic thyroids are positioned in the embryotic decent path that emerges as a lingual thyroid or a thyroglossal duct cyst. It is uncommon for ectopic thyroids to be located in the lateral neck, which only represents 1%-3% of all cases. Any ectopic thyroids that emerge in the posterior lateral neck in pediatric patients should be regarded as an extremely unique case.

Delayed treatment of zygomatic tetrapod fracture.

Since maxillofacial injury is frequently accompanied by other diseases, its evaluation and treatment are open delayed. When the evaluation is delayed, the surgical treatment can be difficult or impossible. A 21-yr-old man presented with right facial swelling and deformity after injury.
