Abstract
Background and Objective The numbers of prescriptions for continuous positive airway pressure and automatic positive airway pressure (APAP) machines have increased dramatically since the Korean government changed national health insurance coverage. This study examined adherence to APAP therapy in patients with obstructive sleep apnea who completed the 3-month adaptation period required by the insurance service, and evaluated the factors predictive of good adherence.Methods We retrospectively reviewed the medical records of a total of 315 patients who received APAP prescriptions between July 2018 and December 2019. After screening, 189 patients were analyzed. Patients were divided into an adherent (AD) group and a non-adherent (NAD) group based on 9 months’ APAP adherence. Patient demographics, medical history, body mass index and pretreatment polysomnography results, as well as APAP therapy adherence-related variables, the 90th percentile pressure, residual apnea hypopnea status, and type of devices or managers were compared between the two groups.Results We found mean usage times, mean pressures, days with ≥ 4 hours of use a day, and 90th percentile pressures differed significantly between the AD and NAD groups. The device-related data at months 1 and 3 and 9 were similar. One type of device performed differently compared to the other devices, but this did not affect adherence.Conclusions The mean pressure and 90th percentile pressure were the main determinants of adherence in patients who passed a 3-month compliance assessment conducted by the Korean National Institute of Health. The data on adherence at months 1, 3 and 9 were similar.

Abstract
BACKGROUND Diverse immune cells contribute to the pathogenesis of chronic rhinosinusitis (CRS), an inflammatory disease of the nasal cavity and paranasal sinuses. However, whether mucosal-associated invariant T (MAIT) cells are present in human sinonasal tissues remains unclear. Furthermore, the characteristics of sinonasal MAIT cells have not been studied in patients with CRS. OBJECTIVE We investigated the phenotype, function, and clinical implications of MAIT cells in patients with CRS. METHODS Peripheral blood and sinonasal tissue were obtained from patients with CRS with (CRSwNP) or without nasal polyps (CRSsNP) and healthy controls. MAIT cells were analyzed by flow cytometry. RESULTS We found that MAIT cells are present in human sinonasal tissues from healthy controls and patients with CRS. The sinonasal MAIT cell population, but not peripheral blood MAIT cells, from patients with CRSsNP, noneosinophilic CRSwNP (NE-NP), or eosinophilic CRSwNP (E-NP) had a significantly higher frequency of activated cells marked by CD38 expression. In functional analysis, the sinonasal MAIT cell population from NE-NP and E-NP had a significantly higher frequency of IL-17A+ cells but lower frequency of IFN-γ+ or TNF+ cells than control sinonasal tissues. Furthermore, CD38 expression and IL-17A production by sinonasal MAIT cells significantly correlated with disease extent evaluated by the Lund-Mackay computed tomography score in patients with E-NP. CONCLUSIONS Sinonasal MAIT cells exhibit an activated phenotype and produce higher levels of IL-17A in patients with CRSwNP. These alterations are associated with the extent of disease in patients with E-NP.

Abstract
BACKGROUND Exposure to airborne urban particulate matter (UPM) has been closely related to the development and aggravation of respiratory disease, including sinonasal disorders. OBJECTIVE The aims of this study were to investigate the effect of UPM on nasal epithelial tight junctions (TJs) and mucosal barrier function and delineate the underlying mechanism by using both in vitro and in vivo models. METHODS In this study, human nasal epithelial cells (hNECs) and BALB/c mice were exposed to UPMs. UPM 1648a and 1649 b were employed. TJ and endoplasmic reticulum (ER) stress marker expression was measured using western blot analysis and immunofluorescence. TJ integrity and nasal epithelial barrier function were evaluated by transepithelial electric resistance (TER) and paracellular flux. In addition, the effects of N-acetyl-L-cysteine (NAC) on UPM-induced nasal epithelial cells were investigated. RESULTS UPM significantly impaired the nasal epithelial barrier, as demonstrated by decreased protein expression of TJ and ER stress markers in human nasal epithelial cells. This finding was in parallel to reduced transepithelial electrical resistance and increased fluorescein isothiocyanate-dextran permeability. Pretreatment with NAC decreased the degree of UPM-mediated ER stress and restored nasal epithelial barrier disruption in human nasal epithelial cells (hNEC) and the nasal mucosa of experimental animals. CONCLUSION These data suggest that UPMs may induce nasal epithelial barrier dysfunction by targeting TJs and ER stress could be related in this process. Based on these results, we suggest that suppression of this process with an inhibitor targeting ER stress responses could represent a novel promising therapeutic target in UPM-induced sinonasal disease.

Abstract
Background and Objectives: Sinonasal inverted papilloma (IP) is a benign tumor with a locally aggressive nature and a propensity to recur. Many risk factors for recurrence have been reported, but they are still controversial. The aim of this study was to comprehensively assess the demographic data, clinical features, and potential risk factors for recurrence of IP.Subjects and Method: This work is a retrospective review of 382 patients diagnosed with and treated for sinonasal inverted papilloma between 1986 and 2017 at a single tertiary medical center. Demographic data, presence of associated malignancy, information about previous surgeries, tumor location, Krouse stage, surgical approach, follow-up duration, and data on recurrence were obtained.Results: In our study, 31 of 382 cases (8.1%) were associated with malignancy. Mean age was significantly higher in patients with associated malignancy compared to the benign IP group. Of the 351 benign cases, 263 (74.9%) were primary, and 88 (25.1%) were revision cases (residual or recurrent disease). Although the proportion of patients with high Krouse stage or multifocal involvement was high in the revision cases, there was no significant difference in recurrence rate. The 226 patients with a minimum follow-up of 1 year were included for recurrence analysis. Recurrence rate was significantly higher in the conventional surgery group (17.4%) compared to that of the endoscopic and combined surgery groups (8.1% and 3.6%, respectively). Also, the recurrence group showed significantly larger proportion of patients with high Krouse stage and multifocal involvement.Conclusion: Risk factors for recurrence of IP found in this study are comparable to those previously published. Generally, the factors associated with recurrence of IP were prior surgery, clinical stage, involved site, and surgical approach. Therefore, surgeons should always consider these risk factors to reduce the chance of recurrence.

Abstract
BACKGROUND Povidone-iodine (PVP-I) is well known as an antiseptic and exhibits extensive activity against various pathogens. However, due to its uniquely unpleasant nature, it cannot be used locally to deactivate various sinonasal pathogens. Therefore, we developed a PVP-I composite that blocks the unpleasant odor of PVP-I for use as a local antiseptic in the sinonasal cavity and evaluated its effect on bacterial biofilm's formation and elimination in in vivo and in vitro models. METHODS MTT, lactate dehydrogenase, and live/dead staining assay were performed to examine the cellular toxicity of PVP-I composites on the primary human nasal epithelial and RPMI 2650 cells. Crystal violet assay was performed to quantify bacterial biofilm after treating with various agents, including PVP-I and antibiotics. Hematoxylin-and-eosin staining, live/dead staining assay, and scanning electron microscopy were conducted to evaluate the effect of PVP-I on biofilm formation in a mice biofilm model. RESULTS It was observed that the PVP-I composite did not have any significant toxic effect on the nasal epithelial cells. Furthermore, the PVP-I composite effectively inhibited the formation of bacterial biomass within a dose-dependent manner after 48 hours of incubation with Pseudomonas aeruginosa and Staphylococcus aureus. In mice, it effectively eliminated biofilm from the mucosa of the nasal cavity and maxillary sinus at the tested concentrations. CONCLUSION The results of this study indicate that the PVP-I composite is a promising compound that could be used locally to prevent the formation of biofilms and to eliminate them from the sinonasal cavity.

Abstract
OBJECTIVES There is a great deal of interest in the possibility that environmental factors may influence the risk of developing allergic rhinitis (AR) in early life. We investigated the simultaneous effects of mode of delivery and duration of breastfeeding on the development of AR in children. METHODS Data from 1,374 children participating in the Allergic Rhinitis Cohort Study for kids (ARCO-kids study) was analyzed. All subjects were divided into AR or non-allergic rhinitis (NAR) groups. Data on environmental factors, mode of delivery and duration of breastfeeding were collected using a questionnaire. RESULTS Compared with short-term breastfeeding (<6 months), long-term breastfeeding (≥12 months) was significantly associated with a lower prevalence of AR (adjusted odds ratio [aOR], 0.54; 95% confidence interval [CI], 0.34 to 0.88). Children in the AR group also had a higher cesarean delivery rate than those in the NAR group (39.1% vs. 32.8%, P=0.05). Regarding the combined effects of mode of delivery and duration of breastfeeding, long-term breastfeeding with a vaginal delivery strongly suppressed the development of AR, compared to short-term breastfeeding with a cesarean delivery (aOR, 0.47; 95% CI, 0.30 to 0.73). CONCLUSION Long-term breastfeeding (≥12 months) and a vaginal delivery are associated with a lower risk of developing childhood AR.

Abstract
Objectives This study was performed to investigate the effects of aging on nasality and the influence of age-related changes in nasal cavity volume and nasal patency on nasality. Methods A total of 180 healthy Korean-speaking adult volunteers, who had no nasal or voice-related complaints, were enrolled in this study. Nasometry, acoustic rhinometry, and rhinomanometry were performed to obtain the nasalance score, nasal cavity volume, and nasal resistance, respectively. Changes in these parameters with age were analyzed. Results Nasal cavity volume increased significantly, and nasal resistance decreased significantly, with age. The nasalance scores for the nasal passage and oronasal passage decreased significantly with age, while there were no age-related changes in nasalance scores for the oral passage. Conclusion Nasalance scores for the passages containing nasal consonants decreased with age although significant increases were observed in nasal cavity volume and nasal patency with age. Therefore, the age-related decreases in nasalance scores may result from factors other than changes in the nasal cavity.

Abstract
Sinonasal organized hematoma, which has locally aggressive characteristics, is a non-neoplastic disease. We report a rare case of sphenoid sinus organized hematoma causing acute visual loss. A 35-year-old male presented with progressive headaches, retro-orbital pain, and frequent epistaxis. He had a medical history of aplastic anemia and of taking warfarin for a valvular heart disease. On image studies, an expansive soft tissue density lesion with bony destruction was found in his left sphenoid sinus. While waiting for elective surgery, acute visual loss occurred. Emergent endoscopic surgery was performed after correction of abnormal hematological profiles, but his visual disturbance did not improve. Although sphenoid sinus organized hematoma is a rare disease, organized hematoma should be considered in the differential diagnosis for sphenoid sinus lesion with acute visual loss. Rapid and correct diagnosis and timely treatment are essential to prevent permanent sequela.

Abstract
Background and objective Interleukin (IL)-25 has been shown to play an important role in the pathogenesis of chronic rhinosinusitis with nasal polyps. Nasal polyps are associated with chronic inflammation of the mucous membranes in the paranasal sinuses and are involved in extracellular matrix (ECM) accumulation. The aim of this study is to evaluate the effects of IL-25 on myofibroblast differentiation, ECM production and the expression of matrix metalloproteinases in nasal polyp derived fibroblasts (NPDFs) and to determine the molecular mechanism underlying these processes. Materials and methods A total of 40 patients were enrolled in this study for Immunofluorescence studies. Expression of IL17 receptor B was evaluated by real time reverse transcription polymerase chain reaction (PCR) in NPDFs. NPDFs were stimulated with IL-25 for 48 h in the presence or absence of mitogen-activated protein kinase (MAPK) and NF-κB inhibitors or small interfering RNAs (siRNA). The protein levels of fibrosis active mediators were examined using western blotting. Fibroblast migration was evaluated with a scratch assay. The total collagen amount was analyzed with the Sircol collagen assay. Results IL-25 induced α-SMA, fibronectin, and MMP-1 and -13, which were dependent on IL-17RB. IL-25 also induced activation of NF-κB and mitogen-activated protein kinase (MAPKs). By using the specific inhibitor of ERK, p38, JNK and NF-κB (U, SB, SP and Bay), we found that IL-25-induced expressions of α-SMA, fibronectin, and MMPs was regulated by the signaling pathways of MAPKs and NF-κB. IL-25 also induces α-SMA, fibronectin, and MMPs expression through IL-17RB-dependent pathways in NPDFs. The increased migration ability induced by IL-25 was suppressed by the specific inhibitors of MAPKs and NF-κB. Conclusion Our data indicate that IL-25 induced myofibroblast differentiation, fibronectin production, and MMP-1 and -13 expressions through the signaling pathways of MAPKs and NF-κB. in NPDFs and increased expression of IL-25 were also involved in the pathogenesis of nasal polyposis by affecting nasal fibroblasts in chronic rhinosinusitis with nasal polyps.

Abstract
BACKGROUND B cells, plasma cells, and local immunoglobulins, are important as a mucosal immune barrier function, and tend to increase in patients with chronic rhinosinusitis with nasal polyposis (CRSwNP). However, their association with eosinophils' aggregation has not been fully understood. The objectives of this study was to explore whether BAFF expression in the subepithelial area in nasal polyp tissues of CRSwNP was associated with eosinophils' accumulation, and also to evaluate cells which cells produce BAFF. METHODOLOGY Immunohistochemical and immunofluorescence staining were used to analyse expression of BAFF, CD20, immunoglobulin A (IgA) and a proliferation inducing ligand (APRIL) on nasal tissues from CRSwNP patients to control subjects. To identify the relationship between BAFF and tissue eosinophilia, CRSwNP subjects were divided into eosinophilic polyp and non-eosinophilic groups. Double immunofluorescence analysis for BAFF and CD11c or CD11b was performed to identify cells producing BAFF. RESULTS The numbers of BAFF, CD20, and IgA-positive cells in the subepithelial area were significantly higher in the CRSwNP group (both eosinophilic polyps and non-eosinophilic polyps. There were statistically significant correlations between the number of BAFF and CD20-positive cells, CD20 and IgA-positive cells, and BAFF and IgA-positive cells. CD11b-positive were co-localized with BAFF positive cells. CONCLUSION The subepithelial expression of BAFF was associated with increased number of B cells and plasma cells, and increased production of IgA in the patients with CRSwNP, especially eosinophilic nasal polyps. Therefore, BAFF-induced IgA production may be associated with eosinophils' aggregation and degranulation, which cause aggravation of tissue inflammation and finally polyp formation. The expression of BAFF in the subepithelial area may be associated with innate inflammatory cells (CD11b+ cells), such as monocytes, granulocytes, macrophages, and natural killer cells.

Abstract
Background and Objectives Interleukin 10 (IL-10) is a potent anti-inflammatory cytokine. The dysregulation of IL-10 is associated with an enhanced immunopathologic response to infection, as well as with an increased risk for developing numerous autoimmune diseases. In this study, we investigated IL-10 expression in chronic rhinosinusitis with nasal polyps (CRSwNP) and assessed the possible role of IL-10 in the pathogenesis of CRSwNP. Materials and Methods Thirty-five patients with CRSwNP, 12 patients with chronic rhinosinusitis without NP (CRSsNP) and 10 control subjects were enrolled in this study. NP tissues and uncinated tissues (UT) were collected for analysis. Dispersed NP cells (DNPCs) were cultured in the presence or absence of IL-25 and IL-10, and a flow cytometric assay was performed to identify the constitutive cell populations of the DNPCs. Murine NP (n = 18) models were used for the in vivo experiments. Real-time PCR, immunohistochemistry, western blotting analysis and ELISA were performed to measure the expression levels of the selected inflammatory cytokines and inflammation-associated molecules. Results The mRNA expression levels of IL-10, IL-5, IL-17A, IL-25 and interferon gamma (IFN-γ) were significantly higher in the NP tissues than in the UT tissues. Strong positive correlations were observed between IL-10 and a variety of inflammatory cytokines (IL-5, IL-17A, IL-25, IFN-γ) and inflammation-associated molecules (B-cell activating factor; BAFF, CD19). Other than the IL-25 to IL-10 ratio, the expression ratios of the other measured inflammatory cytokines to IL-10 were significantly lower in the CRSwNP group than in the CRSsNP or control groups. Administrating IL-25 into the cultured DNPCs significantly increased the production of IL-10, but administrating IL-10 had no effect on the production of IL-25. Conclusion Increased expression of IL-10, IL-10 related inflammatory cytokine, and IL-10 related B cell activation indicated that IL-10, a potent anti-inflammatory cytokine, has a pivotal role in the pathogenesis of CRSwNPs.

Abstract
We learned a significant lesson about diagnosis & treatment through very interesting experience in the aggressive change after the first surgery. We have to consider complete resection of indefinite GCG as a means of the high priority, despite younger age. Pediatric aggressive GCG is the first published a pediatric case of GCG occurring in the nasal cavity with intracranial invasion.
Introduction Giant cell granuloma (GCG) is a non-neoplastic osseous proliferative lesion of unknown etiology. Although a benign disease process, GCG can be locally destructive. It is extremely rare to have a pediatric case of GCG occurring in the nasal cavity with intracranial invasion. Presentation of case We report a case of an aggressive and recurrent giant cell granuloma with intracranial invasion in a 10 years old female patient which was completely excised with endoscopic craniofacial resection. Discussion A literature review on pathogenesis, diagnosis and management is also performed. Conclusion The most common treatment for giant cell granuloma is surgery, ranging from simple curettage to resection. However, it must be completely excised in cases of aggressive and extensive lesion because of the high recurrence rate after incomplete removal.

Abstract
OBJECTIVE The aim of this study was to investigate the prevalence of olfactory dysfunction and evaluate the relationship between olfactory function and nutritional status, comorbidity, and the results of a neurocognitive test in geriatric patients who do not suffer from neurodegenerative disease. MATERIALS AND METHODS A total of 45 patients who visited the Geriatric Health Center of Chungnam National University Hospital were enrolled in this study. Olfactory function was assessed using a Korean Version of Sniffin' Stick Test II. Cognitive status of all participants was assessed with the MMSE-K (Korean version of the Mini-Mental State Examination). Nutritional status was assessed with body mass index, Mini-Nutritional Assessment (MNA), and serum total protein and albumin. RESULTS A total of 45 participants were enrolled in this study. Of these subjects, 28 were men and 17 were women, with a mean age of 71.7±5.16 years. Nine (20%) were normosmia, 13 (28.9%) were hyposmia, and 23 (51.1%) were anosmia. Thirty-six patients (80%) suffered from olfactory dysfunction (anosmia or hyposmia). MMSE score showed significant correlation with MNA score. There were significant negative correlations between age and total TDI (threshold, discrimination, and identification) score, discrimination score, identification score, and MMSE score. MMSE score showed significant correlation with discrimination score and identification score. However, MNA score did not show any significant correlation with olfactory function test results. CONCLUSION Although olfactory function was not influenced by nutritional status, abilities of discrimination and identification of odors were associated with cognitive function in geriatric patients.

Abstract
OBJECTIVES/HYPOTHESIS Organized hematoma (OH) is a rare non-neoplastic disease. We studied the clinical characteristics of 17 patients with sinonasal OH and those of 75 cases in the English literature. STUDY DESIGN Retrospective review of medical records and systematic review of the literature on OH. METHODS Comprehensive review of the English-language literature on OH was performed. We screened all eligible cases based on initial features, and 75 eligible cases found in 15 publications were analyzed. We also retrospectively analyzed and compared medical records of 17 patients diagnosed with pathologically proven sinonasal OH. Data such as demographics, clinical characteristics, pathologic features, radiologic findings, treatment modalities, and follow-up results were compared to the 75 previously mentioned cases. RESULTS Fifteen cases involved the maxillary sinus, one case involved the frontal sinus, and one case involved the sphenoid sinus. There were six patients over 60 years old, and all were taking an antiplatelet agent. The paranasal sinus computed tomography (CT) of seven patients showed bony destruction of the involved sinus. A review of the available literature revealed mostly similar results with our cases, except for the proportion of patients taking aspirin (5.3%) and sex distribution (male:female = 49:25). CONCLUSIONS We reported 17 cases of OH, including a case of frontal sinus and a case of sphenoid sinus lesion. A large proportion of OH patients had bony destruction of the affected sinus on CT. In these patients, a careful diagnosis should be made to distinguish them from a malignant tumor or other expansile diseases. LEVEL OF EVIDENCE 4.

Abstract
Purpose To evaluate the efficacy and safety of once-daily ciclesonide in comparison to both levocetirizine alone, and a ciclesonide/levocetirizine combination in patients with seasonal allergic rhinitis (SAR) and perennial allergic rhinitis (PAR). Methods Subjects exhibiting moderate to severe allergic rhinitis for longer than 1 year were randomized in an open-label, 3-arm, parallel group, multicenter study. Subjects received 200 µg ciclesonide, 5 mg levocetirizine, or a combination of both. Changes from baseline until the end-of-study visit (2 weeks following) were evaluated by reflective total nasal symptom scores (rTNSSs), reflective total ocular symptom scores (rTOSSs), physician-assessed overall nasal signs and symptoms severity (PANS), and rhinoconjunctivitis quality-of-life questionnaires (RQLQ). Results Significant improvements in rTNSS, PANS, and RQLQ in the ciclesonide monotherapy group were observed in comparison to the levocetirizine alone group. Three individual symptoms of rTNSS, including runny nose, nasal itching, and congestion, were improved in the ciclesonide-treated group. rTOSS scores for ciclesonide monotherapy improved from baseline, but no superiority over levocetirizine was shown. The absolute score and changes in rTNSS and PANS were positively correlated. Ciclesonide spray was more effective than levocetirizine in reducing nasal symptoms in both SAR and PAR patients. Ciclesonide and levocetrizine were well tolerated alone and in combination. Conclusions Our results provide support for an AR and its Impact on Asthma (ARIA) recommendation stipulating that ciclesonide is superior to levocetirizine for the treatment of AR, with tolerable safety. Addition of levocetirizine to ciclesonide did not give further clinical benefit over monotherapy.

METHODOLOGY Immunohistochemical and immunofluorescence staining were used to analyse expression of BAFF, CD20, immunoglobulin A (IgA) and a proliferation inducing ligand (APRIL) on nasal tissues from CRSwNP patients to control subjects. To identify the relationship between BAFF and tissue eosinophilia, CRSwNP subjects were divided into eosinophilic polyp and non-eosinophilic groups. Double immunofluorescence analysis for BAFF and CD11c or CD11b was performed to identify cells producing BAFF. RESULTS The numbers of BAFF, CD20, and IgA-positive cells in the subepithelial area were significantly higher in the CRSwNP group (both eosinophilic polyps and non-eosinophilic polyps. There were statistically significant correlations between the number of BAFF and CD20-positive cells, CD20 and IgA-positive cells, and BAFF and IgA-positive cells. CD11b-positive were co-localized with BAFF positive cells. CONCLUSION The subepithelial expression of BAFF was associated with increased number of B cells and plasma cells, and increased production of IgA in the patients with CRSwNP, especially eosinophilic nasal polyps. Therefore, BAFF-induced IgA production may be associated with eosinophils' aggregation and degranulation, which cause aggravation of tissue inflammation and finally polyp formation. The expression of BAFF in the subepithelial area may be associated with innate inflammatory cells (CD11b+ cells), such as monocytes, granulocytes, macrophages, and natural killer cells.

Abstract
BACKGROUND We investigated the risk factors of the regional lymph node (LN) recurrence in papillary thyroid cancer (PTC) patients underwent thyroidectomy and neck dissection according to the clinicopathologic features, preoperative clinical nodal status and the recurrence in previously dissected or undissected compartment of the neck. METHODS A retrospective analysis was performed on 297 patients who underwent total thyroidectomy and LN dissection between 2004 and 2010. Patients with and without regional recurrence were compared by the various clinicopathological factors. Recurrence-free survival rates were estimated by the Kaplan-Meier and Cox regression method. RESULTS With a median follow-up of 53 months, 22 (7.4%) patients developed regional LN recurrence. Initial LN metastasis and tumor size ⩾1 cm were independent predictive factors for regional recurrence. In patients without preoperative clinical LN, Tumor size ⩾1 cm and extrathyroidal extension were significant risk factors for regional recurrence. In cases with preoperative clinical LN, there was no specific significant factor for recurrence. Tumor size ⩾1 cm, capsular invasion, extrathyroidal extension, and lymphovascular invasion were significant risk factors of regional recurrence in previously dissected compartments. Tumor size ⩾1 cm and extrathyroidal extension were significant predictive factors of regional recurrence in previously undissected compartments. CONCLUSIONS Tumor size and LN metastasis were independent predictors of regional LN recurrence in PTC patients after total thyroidectomy and central neck dissection. Patients with tumor size >1 cm or extrathyroidal extension were more likely to have tumor recur both within the previously dissected field as well as the un-dissected compartments.

Abstract
BACKGROUND Allergic rhinitis (AR) is often accompanied by multiple ocular symptoms. This study aimed to evaluate the prevalence of ocular symptoms and the impact of ocular symptoms on the quality of life in patients with AR. METHODS One thousand one hundred seventy-four patients with AR were enrolled from 24 centers in Korea. They were classified into four groups according to the Allergic Rhinitis and Its Impact on Asthma (ARIA) guideline and also classified into perennial AR (PAR) and seasonal AR groups. All patients were asked to complete the questionnaire regarding the presence of ocular symptoms, such as eye itching, watery eyes, and red eyes. The correlation between ocular symptoms and the rest of the quality-of-life areas in the Mini-Rhinoconjunctivitis Quality of Life Questionnaire (Mini-RQLQ) was also asked. RESULTS Seven hundred nineteen (61.2%) of 1174 patients had ocular symptoms. In detail, the numbers of patients with eye itching, watery eyes, red eyes, and other ocular symptoms were 605 (51.5%), 313 (26.7%), 207 (17.6%), and 66 (5.6%), respectively. Female patients (72.5%) complained of ocular symptoms more commonly than male patients (55.1%). The patients with moderate-severe persistent AR showed the highest prevalence of ocular symptoms. The correlation coefficients between ocular symptoms and the rest of the quality-of-life areas in the Mini-RQLQ were statistically significant (p < 0.05). CONCLUSION Sixty-one percent of Korean AR patients experienced ocular symptoms. The patients who were women and had PAR and more severe AR showed higher prevalence of ocular symptoms. The ocular symptoms might have a significant impact on the quality of life in patients with AR.

Abstract
Background The pathogenesis of nasal polyposis has not been fully understood. Recent studies indicate that there is a subset of CD4+CD25high FoxP3+T cells (regulatory T cells [Tregs]) that express retinoic acid receptor related orphan receptor C (RORC) or IL-17, and these cells might be new proinflammatory cells because of the expression of IL-17 with loss of their suppressive function. The goals of this study were to localize Th17-like Tregs (Th17-like Tregs or RORC+Tregs) in nasal polyps and to investigate the role of staphylococcal enterotoxin B (SEB) on the differentiation of Tregs to RORC+Tregs in vitro. Methods A total of 60 patients were enrolled in this study. Of the 60 patients, 40 had chronic rhinosinusitis with nasal polyps (CRSwNPs), and 20 subjects who were undergoing septoplasty were enrolled as control subjects. The nasal polyps of CRSwNP patients were subclassified as either eosinophilic polyp (EP) and noneosinophilic polyp (NEP) according to the result of hematoxylin and eosin stain. Tissues and whole blood were collected from all subjects. Double immunofluorescent staining and reverse-transcription polymerase chain reaction for RORC and FOXP3 were conducted on the tissues. RORC expressions of Tregs were measured in the tissue using flow cytometry. The proportions of RORC+Tregs subsets and cytokines profiles from the supernatant were measured using flow cytometry after stimulation with SEB. Results The cells that express both RORC and FOXP3 and RORC+Tregs were significantly higher in the nasal polyps, especially in EPs compared with NEPs, and control mucosa. RORC+Tregs in peripheral blood mononuclear cells significantly increase in patients with EPs 24 hours after SEB stimulation in vitro. Conclusion The results indicate that SEB may be involved in the differentiation of Tregs to RORC+Tregs, and these cells may be involved in the pathogenesis of eosinophilic nasal polyposis.

Abstract
OBJECTIVES/HYPOTHESIS Hypoxia-inducible factor-1α (HIF-1α) is considered as a key molecule in regulating Th17:regulatory T-cells (Tregs) balance. The aims of this study were to investigate whether HIF-1α is associated with the RORγ (RAR-related orphan receptor gamma) expression of Tregs in nasal polyps and to verify whether Staphylococcus enterotoxin B (SEB) is involved in this process. STUDY DESIGN Clinical experimental study. METHODS Forty patients with chronic rhinosinusitis with nasal polyposis were enrolled and divided into eosinophilic nasal polyps (EPs) and noneosinophilic nasal polyps (NEPs) according to the proportion of eosinophils. Fifteen subjects who were undergoing septoplasty were enrolled as control subjects. Expression of HIF-1α in the tissue was measured using reverse transcriptase-polymerase chain reaction (RT-PCR), Western blot, and flow cytometry. The mRNA expression of RORC (RAR-related orphan receptor C) and HIF-1α in Tregs separated from tissues were measured by RT-PCR. Double immunofluorescent staining for RORC/FOXP3 and HIF-1α/FOXP3 were conducted on the tissues. Expression of RORC and HIF-1α in Tregs from peripheral blood mononuclear cells (PBMCs) was measured using flow cytometry after stimulation with SEB. RESULTS Expression of RORC and HIF-1α in Tregs was significantly higher in EPs and NEPs compared with control mucosa, and there was a significant correlation between RORC and HIF-1α expression in Tregs. Expression of RORC and HIF-1α mRNA in Tregs separated from the tissues was also significantly higher in nasal polyps compared with control mucosa. Expression of RORC and HIF-1α in Tregs were increased after 24-hour stimulation with SEB in the PBMCs. CONCLUSIONS HIF-1α-induced RORC expression in Tregs may play a key role in the pathogenesis of nasal polyps.

Abstract
OBJECTIVE Staphylococcus aureus enterotoxin B (SEB) might participate in the pathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP). However, the exact mechanism of polyp formation in CRSwNP remains unclear. Since the endoplasmic reticulum (ER) stress response is closely associated with chronic inflammation, we investigated the association between ER stress and SEB in the pathogenesis of CRSwNP. DESIGN AND METHODS Twenty-three CRSwNP patients with eosinophilic polyps (EP) or non-eosinophilic polyps (NEP) and 10 healthy subjects who were undergoing septoplasty were enrolled in this study. ER stress response was investigated using immunohistochemical staining and Western blotting. RESULTS We show in this study that there are significantly more SEB-positive cells and higher production of reactive oxygen species (ROS) in the epithelial layer of EP than NEP or control tissue. Both SEB and protein A were detected strongly in tissues from patients with CRSwNP. We observed SEB induced the ER stress response in RPMI 2650 cells. GRP78 elevation by SEB was reduced by ROS scavenger pretreatment. In addition, the induction of GRP78 and p47 phox was increased significantly in EP compared with NEP or control mucosa. CONCLUSIONS SEB may induce ER stress via ROS production in CRSwNP. Therefore, we suggest that SEB-induced ER stress may play important roles in the pathogenesis of nasal polyposis.

Abstract
Interleukin (IL)-17A is a highly inflammatory cytokine and is known to be produced by Th17 cells. The importance of IL-17A expression in nasal epithelial cells is not well understood. The goal of this study is to explore the expression of IL-17A in nasal epithelial cells in vivo and in vitro. IL-17A and staphylococcal enterotoxin B (SEB) were detected by immunofluorescence (IF) in nasal epithelial cells of control mucosa (n = 10) and nasal polyps (n = 20). Expression of IL-17A, RORC, IL-6, and TGF-β1 was also measured by RT-PCR in the tissue of control nasal mucosa (n = 10) and nasal polyps (n = 20). IL-17A expression was evaluated in the human nasal epithelial cells after SEB stimulation. Finally, IL-17A expression was demonstrated by immunohistochemistry and IF following intranasal SEB instillation in mice. Expression of IL-17A in nasal epithelial cells was higher in nasal polyps compared to control mucosa. There was a significant correlation between IL-17A and SEB detection in nasal polyps using IF. SEB increased IL-17A expression in human nasal epithelial cells, and in epithelial cells of SEB instilled mice. In conclusion, SEB exposure of nasal epithelial cells induces the enhanced expression of IL-17A. SEB may be involved in pathogenesis of nasal polyps by enhancing IL-17A expression in epithelial cells in nasal polyps.

Abstract
OBJECTIVE Cyclooxygenases (COXs) are enzymes that catalyze the conversion of arachidonic acid to prostaglandins. Many studies have suggested that COX-2, the inducible form of COX, is important in carcinogenesis. However, little is known about the pattern of expression of COX-2 in a multistep process of malignant transformation of sinonasal inverted papilloma (IP). In this study, we investigated COX-2 expression in IPs, IPs with dysplasia, IPs with squamous cell carcinoma (SCC), and primary SCCs of sinonasal tract. STUDY DESIGN A retrospective study was conducted. SETTING The setting was a tertiary care referral center. SUBJECTS AND METHODS The expression of COX-2 was evaluated by immunohistochemistry in 56, 7, 18, and 17 cases of IPs, IPs with dysplasia, IPs with SCC, and primary SCCs, respectively. Furthermore, we investigated the possible correlation between the expression of COX-2 and clinicopathologic variables in patients with IPs with SCC and primary SCC patients. RESULTS Positive immunoreactivity for COX-2 was observed in 3 (5.4%) of 56 IPs, 7 (38.9%) of 18 IPs with SCC, and 7 (41.2%) of 17 primary SCCs, whereas it was not observed in IPs with dysplasia. The percentage of tumors with COX-2-positive immunostaining was significantly higher in IPs with SCC and primary SCCs compared with benign IPs. There was no significant correlation between the expression of COX-2 and clinicopathologic variables, such as tumor stage, histologic differentiation, and the proportion of malignant areas in patients with IPs with SCC. CONCLUSION Cyclooxygenase-2 may play an important role in the process of malignant transformation from IP to SCC.

Abstract
OBJECTIVES/HYPOTHESIS The scaffold protein IQGAP1 is a ubiquitously expressed 190 kDa protein that participates in protein-protein interactions, integrating diverse signaling pathways. In this study, we examined the expression of IQGAP1 in sinonasal inverted papillomas (IP) and sinonasal squamous cell carcinomas (SCC), which include IP with SCC (IPcSCC) and SCC alone. We also tried to elucidate whether the amount of IQGAP1 expression is related with any clinicopathologic features of sinonasal SCCs. STUDY DESIGN This was a retrospective study. METHODS The expression of IQGAP1 was analyzed by means of immunohistochemistry. The degrees of IQGAP1 expression and subcellular localization (rim formation) were analyzed with respect to the following clinicopathologic variables: age, gender, T stage, histologic differentiation, local recurrence, and distant metastasis. RESULTS The expression of IQGAP1 was significantly higher in patients with IPcSCC (3.62 ± 0.14), and SCC (2.93 ± 0.34) compared with IP (1.43 ± 0.26). The rim formation scale was significantly higher in IPcSCC (2.39 ± 0.24) compared with IP (1.68 ± 0.15). Distant metastasis in patients with SCC significantly correlated with an increased IQGAP1 rim formation (p = 0.011). Histologic differentiation was also significantly correlated with a positive staining scale for IQGAP1 in IPcSCCs (p = 0.038). CONCLUSION These results indicated that IQGAP1 expression is associated with both the histologic differentiation of IPcSCCs and is present in SCC cases where distant metastasis has occurred.

Abstract
OBJECTIVE To evaluate the apurinic/apyrimidinic endonuclease 1 (APE1) expression in sinonasal squamous cell carcinomas (SCC) and to examine the correlation between APE1 expression patterns and various clinicopathological factors associated with sinonasal SCC that include SCC with inverted papilloma (SCCwIP) and SCC alone. STUDY DESIGN Case-control study. SETTING Chungnam National University Hospital. SUBJECTS AND METHODS The expressions of APE1 were analyzed by means of immunohistochemistry in 30 sinonasal SCC, including 14 SCC patients associated with IP and 16 patients with SCC alone. A total of 19 patients who had been diagnosed with chronic rhinosinusitis with nasal polyposis and who required endoscopic sinus surgery were used as the control group. The degrees of APE1 expression were analyzed with respect to the following clinicopathologic variables: age, sex, T stage, histologic differentiation, distant metastasis, and recurrence. RESULTS Cytoplasmic staining of APE1 was significantly higher in SCC compared with SCCwIP (68.75% vs 14.29%). Cytoplasmic staining of APE1 was significantly associated with T stage (P = .044) in SCC and histologic grade (P = .0025) in sinonasal SCC. Nuclear staining of APE1 was significantly associated with distant metastasis (P = .022) in SCC. CONCLUSION These results suggest that the nuclear and cytoplasmic expression of APE1 may be related to tumor invasiveness and prognosis in sinonasal SCC. The suppression of APE1 expression can potentially be a new target for future sinonasal SCC therapies.

Abstract
BACKGROUND E-cadherin and &#946;-catenin are molecules that mediate cell-cell adhesion in normal epithelium. Aberrant expression of these adhesion molecules results in the loss of intercellular adhesion, with possible cell transformation and tumour progression. We determined the role of E-cadherin and &#946;-catenin in the pathogenesis of sinonasal inverted papilloma (IP) and its malignant transformation. METHODS We determined the expression of E-cadherin and &#946;-catenin by immunohistochemistry in paraffin-embedded tissue of 21 subjects with nasal polyps, 56 with IPs, 7 IPs with dysplasia and 18 IPs with squamous cell carcinoma (SCC). The clinicopathological variables of the IPs with SCC correlated with the degree of expression of E-cadherin and &#946;-catenin. RESULTS The degree of expression of E-cadherin and &#946;-catenin in the cell membrane was significantly lower in IPs with SCC than in nasal polyps and IPs. The degree of expression of &#946;-catenin was significantly lower in IPs with SCC with a malignant proportion > 50% compared to a malignant proportion &#8804; 50%. However, there was no significant association between the degree of expression of E-cadherin and &#946;-catenin and clinicopathological variables, such as age, gender, T stage, tumour differentiation, or SCC type (metachronous vs. synchronous). In addition, there was no significant relationship between recurrence or survival rate in IPs with SCC and the degree of expression of E-cadherin or &#946;-catenin in the cell membrane or nuclear &#946;-catenin. CONCLUSION Decreased expression of E-cadherin and &#946;-catenin in the cell membrane may be associated with carcinogenesis of IPs and help predict malignant transformation in sinonasal IPs.

Abstract
OBJECTIVES/HYPOTHESIS The study group for sinonasal tumors at the Korean Rhinologic Society analyzed the results of the Korean multicenter experience for sinonasal inverted papilloma (IP) surgeries. STUDY DESIGN Multicenter cohort study and retrospective analysis. METHODS In total, 939 patients diagnosed with sinonasal IP treated between 1998 and 2007 at 17 university hospitals were enrolled. Demographic data and information about previous surgeries, the origin and involved site of the tumor, the surgical approach, follow-up duration, recurrence, and the presence of malignancy were collected. There were 361 patients whose follow-up was <12 months who were excluded, and 578 patients were included for recurrence analysis. RESULTS The mean follow-up duration for recurrence analysis was 41.0 months, and 15.7% (91/578) had recurrences, with a mean time to recurrence of 32.6 months. However, the group whose follow-up was longer than 3 years had a higher chance of tumor recurrence. Patients whose IPs involved the frontal sinus or the medial wall of the maxillary sinus had higher recurrence rates. There was no significant difference in recurrence rates according to stage or surgical approach. In the T3 stage of Krouse, the T3-A stage of Furuta, and group B of the Citardi staging system, the endoscopic approach alone resulted in higher recurrence rates. CONCLUSIONS Generally, there were no significant differences in recurrence rates according to clinical stage or surgical approach. Given the rate of delayed recurrence, follow-up of >3 years is required. Moreover, surgeons should always consider combined approaches to reduce the chances of recurrence.

Abstract
Background It has been suggested that sinonasal inverted papilloma (IP) can progress to squamous cell carcinoma (SCC); however, mechanisms of malignant transformation are not fully understood. This study investigated alterations in the expression of cell cycle–related proteins in a multistep process of malignant transformation of IPs. Methods The expression of cell cycle–related proteins, including p53, p21, p16, and p63, was evaluated by immunohistochemistry in 21, 56, 7, and 18 cases of nasal polyps, IPs, IPs with dysplasia, and IPs with SCC, respectively. Furthermore, we determined the possible correlation between the expression of these proteins and clinicopathological variables in patients with IPs with SCC. Results Expression of p53 was found only in 8 of 18 IPs with SCC (44.4%). The frequency of p21 positivity was significantly higher in IPs with dysplasia (71.4%) and IPs with SCC (77.8%) compared with nasal polyps (0%) and IPs (12.5%). A p16 positivity was observed in 82.1% of IPs and 57.1% of IPs with dysplasia, whereas 83.3% of IPs with SCC showed an apparent loss of p16 protein expression. A p63 positivity was found in all specimens, but the percentage of positive cells was significantly increased in IPs with dysplasia and IPs with SCC compared with nasal polyps and IPs. There was no significant correlation between the expression of these proteins and clinicopathological variables, such as tumor stage, histological differentiation, and the proportion of malignant areas in patients with IPs with SCC. Conclusion Alteration of cell cycle–related proteins may contribute importantly to the malignant transformation from IP to SCC.

Abstract
BACKGROUND The optimal resection extent for papillary thyroid microcarcinoma (PTMC) confined within a unilateral lobe remains controversial. MATERIALS AND METHODS We reviewed the medical records of 132 consecutive patients who underwent total thyroidectomy for the treatment of clinically unilateral PTMC between March 2005 and March 2009. The frequency, pattern, and predictive factors for occult contralateral carcinoma in these patients were analyzed with respect to the following variables: age, gender, tumor size, multifocality of primary tumor, presence of perithyroidal invasion, lymphovascular invasion or capsular invasion, presence of central lymph node metastasis, and the presence of coexistent benign nodules in the contralateral lobe based on preoperative evaluation and final pathology. RESULTS A total of 22 patients (16.7%) had occult PTMC in the contralateral lobe. In multivariate analysis, multifocality of the primary tumor (P = 0.026, odds ratio = 7.714) and the presence of coexistent benign nodule in the contralateral lobe by preoperative evaluation (P = 0.036, odds ratio = 3.500) were independent predictive factors for occult contralateral PTMC presence. However, there were no significant differences between the presence of occult contralateral carcinomas and age, gender, tumor size, perithyroidal invasion, lymphovascular invasion, capsular invasion, central lymph node metastasis, and coexistent benign nodules by final pathology. CONCLUSIONS Based on our findings, total thyroidectomy, including the contralateral lobe, should be considered for the treatment of unilateral PTMC if it presents as a multifocal tumor in the unilateral lobe and/or if nodules are found in the contralateral lobe during preoperative evaluation.

Abstract
OBJECTIVE/HYPOTHESIS The purpose of the study was to investigate the effect of intravenous adipose tissue-derived stem cell (ADSC) transplantation on olfactory epithelium regeneration following transection of the olfactory nerve in rats. STUDY DESIGN This was a experimental study using primary cultures of mesenchymal stem cells derived from animal adipose tissue with histological analysis of animal olfactory tissue. METHODS All rats underwent unilateral transection of the olfactory nerve to induce degeneration of olfactory epithelium, and then were observed for regeneration according to time sequences. ADSCs were cultivated from neck adipose tissue of rats, and systemically injected into the experimental group. The control group was injected with phosphate buffered solution, instead of ADSCs. After 30 days, regeneration of olfactory epithelium was observed with olfactory marker protein (OMP) and proliferating cell nuclear antigen. To observe the characteristics of the transplanted ADSCs, olfactory epithelium was stained with von Willebrant factor and OMP. RESULTS After olfactory nerve transection, mature olfactory cells disappeared in 5 days, but gradually regained their thickness with increased cell numbers at approximately 10 to 15 days. By 30 days post-transection, the thickness and cellular composition of epithelium was almost restored to baseline levels pretransection. However, OMP expressions remained decreased compared with day 0 or 3. Systemically injected ADSCs were transplanted into the olfactory epithelium and survived beyond 4 weeks. The ADSCs promoted regeneration of olfactory epithelium in the animal model and differentiated into olfactory receptor neurons and endothelial cells. CONCLUSIONS Our findings suggest the feasibility of ADSC transplantation as a treatment for head trauma-related olfactory dysfunction.

Abstract
CONCLUSION Endoscopic removal, with or without external technique, can be performed in a majority of inverted papilloma cases. This method has subsequent recurrence rates that are comparable to those of more aggressive external techniques and it is more cost efficient with less morbidity. OBJECTIVES To analyze the clinical outcomes of our 21-year experience (1986-2006) in treating inverted papillomas using different treatment modalities. PATIENTS AND METHODS The patients were divided into a conventional surgery group (CSG) and an endoscopic surgery group (ESG) and were staged according to the system developed by Krouse. A retrospective assessment was performed. RESULTS The recurrence rates were 4.3% in ESG and 9.5% in CSG. There was no significant difference in the recurrence rates according to the treatment modality used and the Krouse stage in the two groups. Mean operation time was 72.93+/-18.51 min in the ESG and 112.02+/-56.52 min in the CSG. Mean period of hospital stay was 4.66+/-1.75 days in the ESG and 9.54+/-4.79 days in the CSG. The complication rate was 3.2% in the ESG and 33.3% in the CSG. There was a significant difference in the operation time, length of hospital stay, and complication rate in the two groups.

Abstract
OBJECTIVE To elucidate the clinical characteristics of nasal tuberculosis and to discuss its diagnostic difficulties. STUDY DESIGN Retrospective clinical analysis. RESULTS A total of eight patients presented with nasal tuberculosis during the study period (from January 1989 through December 2006). Six were female and two were male. The patient age varied from 17 to 51 years, with a mean of 31 years. The most commonly involved site was the nasal septum (7 of 8). Perforation of the nasal septum was observed in three cases. Sinus invasion was observed in two cases and required sinus surgery. Six of the cases were a result of primary infections, while two were secondary disease manifestations. All patients were treated with anti-tuberculosis medications, with subsequent improvement with regard to clinical symptoms and physical signs. CONCLUSIONS We present the largest number of nasal tuberculosis cases reported in the medical literature from a single institute. Diagnosing nasal tuberculosis requires a high index of suspicion and occasionally the use of experimental drug treatment options.

Abstract
OBJECTIVE To investigate the validity of the sixth edition of the American Joint Committee on Cancer (AJCC) staging system for sinonasal squamous cell carcinoma. DESIGN A 15-year retrospective case series review. SETTING Multicenter study from tertiary care facilities. PATIENTS Data from 113 patients diagnosed as having and treated for sinonasal squamous cell carcinoma from September 1988 through August 2003 were retrieved. Ninety patients followed up for at least 12 months were included in the study. MAIN OUTCOME MEASURES The TNM staging system and survival rates were analyzed using the Kaplan-Meier method to determine the mean, disease-free, and 5-year survival statistics. The effect of tumor stage on overall survival was assessed with stages defined by the fifth and sixth editions of the AJCC staging systems. RESULTS The overall 5-year survival rate was 59.5%. According to the sixth edition, the survival rates of patients with stages III, IVA, and IVB tumors showed a significant difference (P = .002). In 32 cases, the stages were changed in accordance with the criteria in the sixth edition. The group in which the stage changed from III (fifth edition) to IVA (sixth edition) showed a worse survival rate than the group in which the stage did not change, although the difference was statistically insignificant. The 5-year disease-free survival rates of the group in which the stage did not change and of the group in which the stage changed from III (fifth edition) to IVA (sixth edition) were 64% and 34%, respectively (P = .08). Local recurrence was more frequently observed in the group in which the stage changed from III (fifth edition) to IVA (sixth edition). CONCLUSION The new AJCC staging system seems to be more accurate in predicting the survival rates for patients with advanced but surgically resectable sinonasal squamous cell carcinoma (stage IVA).

Abstract
The nasal cycle in patients with septal deviation was studied by acoustic rhinometric techniques. This study included 24 patients with anteriorly located septal deviations (mean age = 23.5), and 26 normal controls (mean age = 24.7). Data of MCA (minimum cross-sectional area) and NV (nasal volume), collected in 20-minute intervals, were plotted for each subject during 8 hours. Twenty of 24 patients (83%) with septal deviation and 20 of 26 normal subjects (77%) showed at least one complete cycle. Duration of the nasal cycle, which ranged from 100 minutes to 400 minutes, had no statistical difference between the septal deviation group (mean duration of 216 minutes) and the normal control group (mean duration of 227 minutes). The degrees of variation of MCA and NV, defined as Degree of Variation of MCA (%) = 100 (MCAmax - MCAmin)/MCAmax, Degree of Variation of NV (%) = 100 (NVmax - NVmin)/NVmax, which represent the percent change of MCA and NV throughout the study, showed no difference between the wide side and the narrow side, or between the septal deviation group and the normal control group. These findings suggest that the nasal cycle is relatively independent of peripheral anatomic factors for its generation. However, the amplitude of changes of MCA was greater in the wide side, and the sum of both MCAs tended to fluctuate in accordance with the fluctuation of MCA of the wide side. Thus, the nasal cycle seemed to be affected by septal deviation.

Abstract
BACKGROUND Plasma cell granuloma is a rare benign lesion which is found most frequently in the lungs, and a few cases have been described in the head and neck. In the middle ear and mastoid, a case of plasma cell granuloma was reported by Benton et al. METHODS AND RESULTS A 24-year-old woman was seen with a 7-month history of otalgia and decreased hearing. A computed tomographic (CT) scan showed a soft tissue mass occupying most of the mastoid bone. The mass and the contiguous dura were enhanced homogeneously on magnetic resonance imaging (MRI) scan. Microscopic examination showed plasma cell aggregates mixed with other inflammatory cells and Russell's bodies in a fibrous stroma. Immunoperoxidase studies revealed intracytoplasmic kappa and lambda light chains, and the lesion was confirmed as non-neoplastic and of polyclonal origin (ie, plasma cell granuloma). The patient was treated with conservative surgical excision (a canal-down mastoidectomy) and postoperative radiotherapy (5,040 cGy in 28 fractions) and remains free of disease 1 year after treatment. CONCLUSIONS A case of plasma cell granuloma is reported, and we believe this is the second case report of plasma cell granuloma affecting the temporal bone.

Abstract
Immunohistochemistry combined with electron microscopy was employed to investigate the distribution of substance P-immunoreactive (SP-IR) nerve fibers in the tracheal submucosal gland of cats. The SP-IR nerve fibers were found to form a network around the glands. Numerous varicosities were also detected within the basement membrane of the acini and secretory tubules. All the intraglandular varicosities showed close spatial contact with serous cells, mucous cells, and myoepithelial cells. Our findings suggest that substance P-induced mucus secretion from tracheal submucosal glands in cats may be caused not only by a glandular contractile response of myoepithelial cells, but also by direct stimulation to both serous and mucous cells.
