BACKGROUND AND OBJECTIVES The volume of the air cavities in the paranasal sinuses is not only the simplest, but also the most important index for paranasal sinus evaluation. However, few volumetric studies have been performed in all age groups. The purpose of the current study was to outline the normal development of paranasal sinuses in all age groups, and(More)
The aim of this study was to characterize the association between trait anhedonia and regional gray matter volume in patients with schizophrenia. Forty-six patients with schizophrenia and 56 healthy controls underwent magnetic resonance imaging (MRI) to acquire high-resolution T1-weighted images. Trait anhedonia was measured using the Chapman Revised(More)
Pott's puffy tumor is an infrequent entity characterized by a subperiosteal abscess associated with frontal bone osteomyelitis. It has become rare due to the development of antibiotics and is usually seen as a complication of frontal sinusitis. Although Pott's puffy tumor is more commonly described in children, it should also be included in the differential(More)
OBJECTIVE The objective of this study was to explore the possibility of the use of Virtual Reality Functional Skills Assessment (VRFSA) in a future regular clinical trial, as well as to report a preliminary result about effectiveness of atypical antipsychotics to social competence in schizophrenia. METHODS We developed the VRFSA that measured subjects'(More)
BACKGROUND Noninvasive evaluation of nasal airflow has remained a constant challenge for clinicians. A recently developed method for measurement of nasal obstruction has been evaluated. This study was designed to compare results of nasal sound spectral analysis (NSSA) with results of peak nasal inspiratory flow (PNIF) and visual analog scale (VAS) of nasal(More)
PURPOSE Based on the close relationship between histamine and interleukin 6 (IL-6), we hypothesized that histamine may regulate the production of cytokines, such as IL-6, during allergic inflammation. Here, we examined the role of histamine in IL-6 production and histamine receptor activity in nasal fibroblasts, along with the mechanisms underlying these(More)
OBJECTIVE Sublingual immunotherapy is currently accepted as a suitable alternative to subcutaneous immunotherapy because of its easy and painless administration and improved safety. Many clinical trials have demonstrated that sublingual immunotherapy is an effective and safe treatment for pollen or mite allergic rhinitis. However, there have been very few(More)
BACKGROUND Allergy test results can differ based on the method used. The most common tests include skin-prick testing (SPT) and in vitro tests to detect allergen-specific IgE. This study was designed to assess allergy test results using SPT, individual specific IgE tests, and a multiallergen IgE assay (multiple allergen simultaneous test) in patients with(More)
OBJECTIVES Caffeic acids are known to have anti-oxidant, anti-inflammatory, immunomodulatory, and tissue reparative effects. The purposes of this study were to determine the effect of caffeic acid on transforming growth factor (TGF) β1-induced myofibroblast differentiation and collagen production, and to determine whether caffeic acid is involved in the(More)
BACKGROUND Macrolides are known to have anti-inflammatory, immunomodulatory, and tissue reparative effects. The purpose of this study was to determine the effect of macrolides (erythromycin [EM] and roxithromycin [RXM]) on the differentiation of fibroblasts into myofibroblasts and extracellular matrix accumulation in transforming growth factor (TGF)(More)
