BACKGROUND Staphylococcus aureus is a common bacterial pathogen associated with chronic rhinosinusitis with/without nasal polyps (CRSw/sNP). We investigated the effect of S. aureus on the secretion of eotaxin, interleukin (IL)-5, IL-8, IL-13, matrix metalloproteinase (MMP) 2, MMP-9, and tissue inhibitor of MMP (TIMP) 1 in nasal mucosae from CRSwNP patients(More)
OBJECTIVE Tutoplast-processed fascia lata (TPFL) is a commercially available homograft, which has been successfully used as human graft tissue for physical support procedures. The present report evaluates the use of TPFL in rhinoplasty. STUDY DESIGN AND SETTING The study involved a retrospective analysis of rhinoplasty cases using TPFL. The study(More)
OBJECTIVES/HYPOTHESIS Viral upper respiratory tract infections are often followed by secondary bacterial infections in the form of acute rhinosinusitis. We investigate the effect of rhinovirus infection on the expression of cell adhesion molecules and bacterial adherence to primary human nasal epithelial cells. METHODS Cells were infected with rhinovirus(More)
BACKGROUND Using A549 alveolar epithelial type II-like cells, we investigated the effects of cigarette smoke on the expression of rhinovirus (RV)-induced Toll-like receptor (TLR) 3, interleukin (IL)-6, and IL-8 secretion and viral replication. METHODS Cigarette smoke extract (CSE) was prepared by smoking two commercial cigarettes with filters (0.9-mg of(More)
OBJECTIVES/HYPOTHESIS Postviral olfactory dysfunction (PVOD) develops after a common cold, but little is known about the viral pathogen inducing olfactory dysfunction. We hypothesized that human parainfluenza virus 3 (PIV3) may cause PVOD. We therefore assayed the nasal cavity mucosae of PVOD patients for the presence or persistence of PIV3. METHODS We(More)
CONCLUSION While the complication rate for silicone sheets was similar to that reported for silicone rubber, there are several advantages to the use of silicone sheets for correcting minor dorsal irregularities. Therefore, silicone sheets can be used as a versatile graft material for dorsal augmentation in rhinoplasty. OBJECTIVES Silicone implants mostly(More)
OBJECTIVES Retention cysts of the maxillary sinus are an incidental finding on radiographs. These cysts usually appear as rounded, dome-shaped, soft tissue masses, most often on the floor of the maxillary sinus. The aim of this study was to investigate the long-term natural course of retention cysts of the maxillary sinus. METHODS Between November 1997(More)
We have evaluated the usefulness of direct soft tissue measurements in profile photographs for determining the nasal proportions and angles of young Korean individuals and those of rhinoplasty patients, and we compared these findings with existing norms of Caucasian populations. We retrospectively compared preoperative profile measurements of nasal length,(More)
The objective of this study was to evaluate the effect of dietary supplementation of antibacterial peptide and zinc methionine on performance and some serum biochemical parameters of weaned piglets. Rongchang male piglets (28 days of age, initial weight 8.4 ± 0.65 kg) were used. All piglets were randomly allotted to four diets including the control group,(More)
OBJECTIVE To analyze the incidence of prolonged epiphora after maxillectomy according to transected nasolacrimal duct management technique, type of tumor, radiotherapy, and timing of tube removal and performance of dacryocystorhinotomy. DESIGN Retrospective medical record review. Settings University hospitals. PATIENTS We studied 89 patients (90 cases)(More)
