Abstract
Erdheim-Chester disease is characterized by the infiltration of foamy histiocytes in tissues. Lesional tissue biopsy is recommended to confirm diagnosis and establish the BRAF mutational status. A 52-year-old man presented to our hospital with hydronephrosis. Computed tomography showed enhancement of soft shadows around the left renal pelvis transition area and the aorta. He was treated with prednisolone 0.2 mg/kg for 1 year; however, no improvement was observed. 18Fluorodeoxyglucose-positron emission tomography/computed tomography revealed increased fluorodeoxyglucose uptake in various body parts, including the maxillary sinuses, indicative of Erdheim-Chester disease. He refused further examination, and the maxillary sinus lesions were treated with antibiotics and intranasal steroids, but no improvement was observed. Two years later, he underwent biopsy with endoscopic sinus surgery of the maxillary sinus, which showed the highest increase in fluorodeoxyglucose uptake on repeat 18fluorodeoxyglucose-positron emission tomography/computed tomography. Endoscopic findings showed only nonspecific inflammatory findings, but pathological findings revealed the proliferation of cells with abundant foamy cytoplasms. Sufficient tumor volume was available to perform PCR for BRAF V600E mutation analysis, which was positive and resulted in a diagnosis of Erdheim-Chester disease with the BRAF V600E mutation. This is the first case of a patient with Erdheim-Chester disease with the BRAF V600E mutation identified in a sinus lesion. Endoscopic sinus surgery biopsy of the paranasal sinuses was considered to contribute to the histological and genetic diagnosis of Erdheim-Chester disease, particularly following the notable increase in fluorodeoxyglucose uptake.

Abstract
Introduction Sensory dysfunctions and cognitive impairments are related to each other. Although a relationship between tinnitus and subjective olfactory dysfunction has been reported, there have been no reports investigating the relationship between tinnitus and olfactory test results. Methods To investigate the relationship between tinnitus and olfactory test results, we conducted sensory tests, including hearing and visual examinations. The subjects included 510 community-dwelling individuals (295 women and 215 men) who attended a health checkup in Yakumo, Japan. The age of the subjects ranged from 40 to 91 years (mean ± standard deviation, 63.8 ± 9.9 years). The participants completed a self-reported questionnaire on subjective tinnitus, olfactory function, and hearing function, as well as their lifestyle. The health checkup included smell, hearing, vision, and blood examinations. Results After adjusting for age and sex, the presence of tinnitus was significantly associated with subjective olfactory dysfunction, poor olfactory test results, hearing deterioration, vertigo, and headache. Additionally, high serum calcium levels and a low albumin/globulin ratio were significantly associated with low physical activity and nutrition. Women scored higher than men in olfactory and hearing examinations, but there was no gender difference in vision examinations. Conclusion Subjective smell dysfunction and poor smell test results were significantly associated with tinnitus complaints. Hearing and vision were associated even after adjusting for age and sex. These findings suggest that evaluating the mutual relationships among sensory organs is important when evaluating the influence of sensory dysfunctions on cognitive function.

Abstract
AIM Olfactory impairment is associated with cognitive impairment. However, differences between subjective and objective olfactory impairment measurements in older adults and their relationship with cognitive impairment are unclear. METHODS We assessed the relationship between cognitive and olfactory impairments via a single-center observational study in 2020. Forty-seven individuals who visited our memory clinic were enrolled and asked to complete objective and subjective olfactory tests. Participants had dementia, mild cognitive impairment, or normal cognition. We administered the Open Essence (a simple card-type odor identification test) and self-administered odor questionnaire to assess objective and subjective olfaction, respectively, and the Mini-Mental State Examination to assess cognitive function. RESULTS Older age was related to decreased Open Essence scores (P < 0.001). Compared with the mild cognitive impairment and normal cognition groups, the dementia group had significantly lower Open Essence scores (P < 0.001). Cognitive impairment was also associated with decreased Open Essence scores after adjusting for age, sex, and education (P < 0.001). Participants with dementia did not obtain lower self-administered odor questionnaire scores than those with normal cognition, and they tended to be unaware of their olfactory impairment. CONCLUSION Open Essence scores significantly decreased according to the degree of cognitive impairment. Participants with dementia were unaware of their olfactory impairment, as indicated by odor questionnaire scores. Objective and subjective scores of olfaction differed in participants with dementia. Concomitant assessment of objective and subjective olfaction is useful to screen older adults with both olfactory and cognitive impairments.

Abstract
We summarize the presence of endolymphatic hydrops (EH) in otological disorders evaluated with magnetic resonance imaging (MRI) of temporal bones, and propose a classification of EH based on its pathological significance. A search of the literature published in English-language journals was performed using electronic databases, especially focusing on EH-related otological disorders. Clinical articles that contained the terms EH and contrast-MRI published from 2007 to the present, with relevant human temporal bone studies, were included. The following three main points are discussed based on the results in the relevant articles: i) otological disorders that present EH, ii) current grading for evaluation of EH on MRI, and iii) a proposed classification of EH based on its pathological significance. MRI evaluation revealed that EH exists extensively not only in ears with typical Meniere's disease (MD), but also in those with various other otological disorders. The etiological classification of EH helps to summarize ideas for determining the pathophysiology of otological disorders, while a therapeutic classification provides clues to their management. MRI evaluations of EH have led to breakthroughs in investigations of EH in otological disorders. Precise grading for evaluation and clarification of EH on MRI based on its pathological significance could provide keys to elucidating the pathophysiology of EH-related otological disorders.

Abstract
We investigated the associations between hearing aids (HA) and the maintenance of cognitive function among community-dwelling older adults with moderate hearing loss. A total of 407 participants aged 60 years or older with moderate hearing loss were recruited from the National Institute for Longevity Sciences, Longitudinal Study for Aging (NILS-LSA). Moderate hearing loss was defined as a pure-tone average of 40–69 dB at 500, 1000, 2000, and 4000 Hz of the better ear, according to the definition proposed by the Japan Audiological Society. Cognitive function was evaluated using the four subtests of the Japanese version of the Wechsler Adult Intelligence Scale-Revised Short Forms (WAIS-R-SF): Information, Similarities, Picture completion, and Digit Symbol Substitution (DSST). A longitudinal analysis of 1192 observations with a mean follow-up period of 4.5 ± 3.9 years was performed. The HA use rate at any time during the follow-up period was 31.4%, and HA users were significantly younger (t-test, p = 0.001), had worse hearing (p < .0001) and higher education (p = 0.001), participated more frequently in the survey (p < .0001), and were less depressed (χ2 test, p = 0.003) than the older adults not using HA. General linear mixed models consisted of the fixed effects of HA use, follow-up time, and an HA use × time interaction term adjusted for age and pure-tone average thresholds at baseline, sex, education, and other possible confounders. HA use showed significant main effects on the scores for Picture completion and DSST after adjustment; scores were better in the HA use group than in the no HA use group. The HA use × time interaction was significant for the Information score (p = 0.040). The model-predicted 12-year slope with centralizing age indicated that the no HA use group showed greater decline over time on Information scores than did HA use group. The slopes did not differ between HA users and non-users for the Similarities, Picture completion and DSST. In conclusion, HA use may have a protective effect on the decline in general knowledge in older adults with moderate hearing loss.

Abstract
BACKGROUND Otological diseases including Meniere's disease (MD) involve endolymphatic hydrops (EH), which can be visualized by magnetic resonance imaging (MRI) with gadolinium contrast agents, but the temporal changes of contrast in the inner ear have not been evaluated. OBJECTIVES We investigated the permeability of the blood-perilymph barrier (BPB) in ears with EH to evaluate the severity of the inner ear disturbances. MATERIALS AND METHODS The study included 32 ears from 16 patients with EH or related diseases who underwent MRI. The permeability of the BPB was assessed by the signal-intensity ratio (SIR) at four-time points: before and at 10 min, 4 h, and 24 h after administration of gadolinium for assessing EH. RESULTS Cochlear EH was found in 25 of the 32 ears, and vestibular EH in 11. The rate of EH was significantly higher in symptomatic ears; however, the existence of EH was not related to SIR values. Nevertheless, SIR values in the basal turn were significantly higher 4 and 24 h after injection of gadolinium in patients aged ≥50 years. CONCLUSION AND SIGNIFICANCE Higher SIR values observed in older patients with EH indicate severe disturbances of the BPB in the cochlea, which may account for intractable inner ear disturbances in older patients.

Abstract
OBJECTIVES To investigate the clinical features of ears with dilatation of the endolymphatic space in the ampulla of the posterior semicircular canal on magnetic resonance imaging. STUDY DESIGN Retrospective study. SETTING A university hospital. METHODS This study included 1,842 ears from 934 patients who underwent 3-T magnetic resonance imaging with gadolinium to investigate the presence of endolymphatic hydrops. Age, sex distribution, hearing thresholds on pure-tone audiometry, and vestibular symptoms were compared between cases of unilateral and bilateral dilatation of the endolymphatic space in the ampulla of the posterior semicircular canal. RESULTS Forty-eight ears (17 men and 14 women; mean age 49.9 yrs) showed dilatation of the endolymphatic space in the ampulla of the posterior semicircular canal. Age and the rate of chronic sensorineural hearing loss were significantly higher in the unilateral group (14 ears) than in the bilateral group (34 ears). The average hearing thresholds and rates of vestibular symptoms reported did not differ between unilateral and bilateral cases, but some patients showed positional nystagmus. CONCLUSIONS Dilatation of the endolymphatic space in the ampulla was observed selectively in the posterior semicircular canal, though its pathogenesis was not clear. Such dilatation is not usually accompanied by vestibular endolymphatic hydrops, and it may be a cause of vertigo and dizziness.

Abstract
OBJECTIVE The influence of living alone on multiple food and nutrition behaviors across a range of ages and genders has not been sufficiently investigated. Moreover, to our knowledge, no studies have described both dietary status and medical examination findings in persons living alone. Among individuals who attended a health checkup in a rural town in Japan, we investigated dietary habits and medical examination findings in persons living alone and those living with one or more other persons. METHODS The participants in this investigation were 501 community-dwelling individuals aged 40 to 91 y (mean, 63.8 ± 9.9 y). Thirty-four (16.4%) of the 207 men and 45 (15.3%) of the 294 women lived alone. Dietary intake frequency of 28 types of foods and drinks, including various vegetables, fruits, meat, seafood, and dairy products, was investigated based on responses to a self-completed questionnaire. During the physical examination, body weight, body mass index, body fat percentage, and blood pressure (systolic and diastolic) were measured. Blood examination included red blood cell count, white blood cell count, platelet count, hemoglobin, hematocrit, total protein, albumin/globulin ratio, total cholesterol, triglyceride, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, creatinine, blood urea nitrogen, uric acid, and serum calcium. RESULTS Multivariate analysis revealed that living alone independently was associated with a reduced intake frequency of various vegetables and seafood, especially in men. Diastolic blood pressure and triglyceride levels were significantly higher in men living alone than in men living with other persons. The albumin/globulin ratio in women living alone was significantly lower than in women living with other persons. CONCLUSIONS It was found that living alone was associated not only with a reduced quality of dietary intake but also with an unfavorable trend in some of the medical examination findings.

Abstract
OBJECTIVE Hearing loss is a risk factor for cognitive impairment, and the use of a hearing aid (HA) may prevent cognitive decline alongside hearing loss. We aimed to elucidate the prevalence of self-reported HA usage in Japanese community-dwelling elders with hearing loss, and the effect of hearing and HA on cognitive impairment. METHODS A total of 1193 participants, who had audiometric defined hearing loss and were aged 60 years or over, had their cumulative 3260 observations followed up for 10 years from a large cohort of a Japanese study. Association between hearing (pure-tone average threshold level at 500, 1000, 2000, and 4000 Hz from the better hearing ear: PTABHE) and HA usage with cognitive impairment (total score of Mini-Mental State Estimation was under 27 or diagnosed as dementia) was analyzed using generalized estimating equations. RESULTS The HA usage rate of the 1193 community-dwelling elders with hearing loss was 6% during the first involvement. The majority (59.2%) of HA users always used an HA. HA usage rate was 0.7% for the mild hearing loss group and 32.4% for the moderate or greater hearing loss group in the latest participating wave. PTABHE was significantly associated with cognitive impairment (odds ratio for every 10 dB 1.36; 95% CI 1.21-1.53, p<0.0001) after adjusting for age, sex, education, depressed mood, smoking status, alcohol intake, income, activity, obesity, histories of hypertension, dyslipidemia, ischemic heart disease, diabetes, stroke, ear disease, and occupational noise exposure. PTABHE was also significantly associated with cognitive impairment in the mild hearing loss group (odds ratio for every 10 dB 1.34; 95% CI 1.05-1.72, p = 0.020) and moderate hearing loss group (odds ratio for every 10 dB 1.82; 95% CI 1.27-2.61, p = 0.001). HA use showed a significant suppressive effect on cognitive impairment in those with moderate hearing loss who always use an HA (odds ratio 0.54; 95% CI 0.30-1.00, p = 0.049). CONCLUSION The prevalence of HA usage among Japanese community-dwelling elders with hearing loss is consistent, at around 10%. The hearing level remained a primary risk factor for cognitive impairment among elders with hearing loss after adjusting for several confounding factors. Regular HA use may have a protective effect on cognitive impairment in those with moderate hearing loss.

Abstract
BACKGROUND High signals in the inner ear of idiopathic sudden sensorineural hearing loss (ISSNHL) on magnetic resonance imaging (MRI) have been reported, but no quantitative evaluation has yet been done. OBJECTIVES To evaluate hearing outcomes and cochlear signal intensities on 3-T heavily T2-weighted three-dimensional fluid-attenuated inversion recovery magnetic resonance imaging (hT2W-3D-FLAIR) in patients with ISSNHL. MATERIALS AND METHODS Twenty-nine patients with ISSNHL were included. Patients underwent hT2W-3D-FLAIR with intravenous gadolinium injection and pure tone audiometry (PTA) at initial visits and 3 months later. Signal intensity ratios (SIRs) were measured in the basal or apical-middle turns of the affected cochlea. A statistical analysis of relationships between SIRs and the average hearing levels (HLs) at low (125, 250, and 500 Hz) and high (2, 4, and 8 kHz) tone frequencies was performed. RESULTS Hearing improvements at high-tone frequencies in ears with HLs ≥60 dB were significantly worse in those with high SIRs at the basal turns on pre-contrast images. Similarly, hearing improvements at low-tone frequencies in ears with HLs ≥60 dB were significantly worse in those with high SIRs at the apical-middle turns on post-contrast images. CONCLUSIONS AND SIGNIFICANCE High SIRs on hT2W-3D-FLAIR indicate cochlear disturbances with severe ISSNHL and could provide lesion-specific prognostic information.

Abstract
BACKGROUND High signal intensity in the endolymphatic duct (ED) is occasionally observed on magnetic resonance imaging (MRI) in ears that have otological disorders. OBJECTIVE The signal intensity (SI) in the ED on post-contrast MRI was investigated in subjects with various otological disorders, and the meaning of high SI in the ED was evaluated. MATERIAL AND METHODS 392 patients with otological disorders and 21 controls without otological symptoms underwent 3 T MRI. The SIs of the ED and the cerebellum were measured, the SI ratio (SIR) was calculated, and ears with SIR ≥4 were identified. RESULTS A high SIR was identified in the ED of 3.7% of ears affected by definite Meniere's disease (dMD), 100% of ears affected by large vestibular aqueduct syndrome (LVAS), and 7.1% of ears with no otological symptoms. On the whole, a significant relationship was found between the existence of vestibular or cochlear EH and the SIR in the ED. CONCLUSION The MRI finding of high SI in the ED may indicate the mechanism of inner ear disturbances in ears with otological disorders, especially in those with LVAS, and it may suggest an underlying disorder in some ears in which otological symptoms are not apparent.

Abstract
Background: The presence of endolymphatic hydrops (EH) may cause hearing loss and affect the transmission of acoustic energy to the inner ear.Objectives: Acoustic energy absorbance on wideband acoustic immittance (WAI) was evaluated, focusing especially on EH in the vestibule.Material and methods: A total of 32 ears from 16 patients who underwent 3-T magnetic resonance imaging (MRI) to evaluate the presence of EH were examined, retrospectively. The degree of EH in the vestibule was classified into three grades (no, mild, and significant), and pure tone audiometry (PTA) and WAI were measured before and after a glycerol drip.Results: Ears with significant EH showed significantly higher hearing levels and air-bone gaps (ABG), and higher absorbance values on WAI at low frequencies (560-600 Hz) than ears with mild or no EH. Changes in absorbance values were observed in some ears without threshold change on PTA.Conclusions and Significance: This study showed significantly higher absorbance values of acoustic energy with significant vestibular EH at low frequencies. Considering ABGs observed in ears with significant EH, the presence of EH in the vestibule might cause an obstacle to the transmission of acoustic energy to the inner ear.

Abstract
BACKGROUND Though the relationship between chronic rhinosinusitis (CRS) and lower airway diseases is well recognized, the impact of CRS on bronchial wall structure has not been elucidated. Here, we evaluated the bronchial wall structure of CRS patients with or without diagnosed airway diseases by three-dimensional computed tomography (3D-CT). METHODS Subjects who underwent both chest CT and sinus CT within a year were recruited from consecutive medical records. CRS was defined as a Lund-Mackay score (LMS) of over 5 points. Airway dimensions were measured using validated software. Standard blood tests and pulmonary function tests were performed, and their correlation with airway thickness was examined. RESULTS One-hundred-seventy-two patients were recruited (93 CRS subjects and 79 non-CRS subjects). The bronchial walls of CRS subjects were significantly thicker than those of non-CRS subjects. CRS and asthma were related to bronchial wall thickening by multivariate linear regression analysis adjusted for age, smoking status, and chest symptoms. In addition, LMS was significantly correlated with bronchial wall thickening. CONCLUSION Airway walls in CRS subjects were thicker than those in non-CRS subjects and associated with the severity of CRS. These data indicate strong relationship between upper and lower airways regardless of chest symptoms or diagnosed airway diseases.

Abstract
OBJECTIVES The pathology of sudden sensorineural hearing loss, which is known as sudden deafness (SD), remains unknown. The purpose of this study was to investigate the association between mitochondrial uncoupling protein 2 (UCP2) polymorphism and SD risk. MATERIALS AND METHODS We compared 83 patients suffering from SD and 2048 controls who participated in the Longitudinal Study of Aging at the National Institute for Longevity Sciences. Multiple logistic regression was used to calculate the odds ratios (ORs) for SD with a polymorphism of the UCP2 (rs660339) gene. RESULTS Under the additive model of inheritance, UCP2 polymorphisms showed significant association with a SD risk. The OR was 1.468 (95% confidence interval, 1.056-2.040) with an adjustment for any past history, such as diabetes, dyslipidemia, or hypertension, and for age and sex. CONCLUSION Our results imply that the UCP2 (rs660339) polymorphism has a significant association with the risk of developing SD.

Abstract
We investigated the otological aspects of Fabry disease (FD) in patients with normal hearing. Forty-one patients (21 men, 20 women) with bilaterally normal hearing were recruited, and their otological symptoms and hearing evaluations, which included pure tone audiometry (PTA) and distortion product otoacoustic emission (DPOAE), were investigated. Ten of the 21 male (47.6%) and eight of the 20 female (40.0%) patients had otological symptoms, of which tinnitus was the most frequent. Cardiac dysfunction was more frequently observed in female patients. The average thresholds on PTA were below 25 dB at all frequencies, but DPOAE amplitudes were significantly lower in female patients at some frequencies. Otological symptoms were frequently observed in patients with FD, despite their normal hearing levels on PTA. DPOAE might provide useful information regarding cochlear disturbances related to the disease..

Abstract
BACKGROUND Asthma often coexists with chronic rhinosinusitis (CRS). Recent studies revealed that sinus inflammation in asthmatic patients was related to eosinophilic inflammation. However, the relationship between the severity of CRS and four different sputum inflammatory phenotypes as defined by the proportion of eosinophils and neutrophils is unknown. The aim of this study was to examine the impact of the severity of CRS on lower airway and systemic inflammation in asthmatic patients. METHODS We enrolled 57 adult asthmatic patients who underwent sinus computed tomography (CT). The severity of CRS was evaluated by the Lund-Mackay score (LMS). The induced sputum inflammatory phenotype was defined by eosinophils (≥/<2%) and neutrophils (≥/<60%). Peripheral blood mononuclear cells (PBMC) were collected to examine cytokine productions. RESULTS The median LMS of subjects was 6 (interquartile range, 0-11.5). The sputum inflammatory cell phenotype was categorized as paucicellular (n = 14), neutrophilic (n = 11), eosinophilic (n = 20), or mixed (n = 12). LMS was positively correlated with the percentage of blood eosinophils, sputum eosinophils, and mean fluorescence intensity (MFI) of IL-5 on CD4+ T cells. In the severe CRS group (LMS, 12-24), the number of mixed cellular phenotypes was higher than that in the group without CRS (LMS, 0-4) and mild-to-moderate CRS group (LMS, 5-11). CONCLUSIONS In asthmatic patients with severe CRS, the proportion of the mixed cellular inflammatory phenotype was increased as well as eosinophilic inflammation.

Abstract
Background and Purpose: In the horizontal canal benign paroxysmal positional vertigo (BPPV), cupulolithiasis shows apogeotropic direction changing nystagmus lasting more than 1 min, while canalolithiasis leads to geotropic direction changing nystagmus lasting < 1 min. The difference between cupulolithiasis and canalolithiasis is widely accepted to be the attachment of the displaced otoconia to the cupula of a semicircular canal. Several studies have shown a relationship between BPPV and vitamin D deficiency, but no studies have compared serum levels of vitamin D between canalolithiasis and cupulolithiasis patients. The purpose of this study was to clarify the difference in vitamin D serum level between canalolithiasis and cupulolithiasis of the horizontal canal. Methods: This retrospective study included 20 and 15 patients with canalolithiasis and cupulolithiasis of the horizontal canal, respectively. Serum levels of 25-hydroxyvitamin D [25(OH)D] during the acute phase of BPPV were measured. Results: The mean 25(OH)D serum level in patients with canalolithiasis and cupulolithiasis was 13.2 ± 1.4 and 20.4 ± 1.6 ng/mL, respectively, and the difference was statistically significant (p = 0.0014), also after adjusting for age and sex (p = 0.0351). Eighteen out of 20 (90%) and 5 of 15 (33%) patients were diagnosed with vitamin D deficiency in the canalolithiasis and cupulolithiasis groups, respectively, and this difference was also statistically significant (p = 0.0005). Conclusion: We found that serum vitamin D level in patients with canalolithiasis was significantly lower than that in patients with cupulolithiasis of the horizontal canal.

Abstract
BACKGROUND Diverticula in the internal auditory canal (IAC) have been reported in ears with otosclerosis. OBJECTIVE We evaluated hearing levels and vascular activity in ears with otosclerosis with and without IAC diverticula and clarify the significance of IAC diverticula. MATERIALS AND METHODS Sixty-one ears from 54 patients who underwent stapes surgery for otosclerosis [fenestral (48 ears) and retrofenestral (13 ears) groups] were included in the present study. Preoperative hearing levels on pure tone audiometry (PTA) and intraoperative measurements of blood flow were compared between the groups. RESULTS A total of 24 of 61 ears (39.3%) showed IAC diverticula, significantly higher than the frequency in ears without otosclerosis (3.7%). No significant differences in air- and bone-conduction thresholds on PTA were evident between ears with and without IAC diverticula in each group. Ears without IAC diverticula tended to show higher blood flow in the area anterior to the oval window than ears with IAC diverticula, but the difference was not significant. CONCLUSIONS The incidence of the IAC diverticula in otosclerosis was significantly higher than in cases without otosclerosis. The existence of IAC diverticula was not evidently related to the severity of the disease from the perspective of hearing level and vascular activity.

Abstract
CONCLUSIONS The presence of endolymphatic hydrops (EH) in the vestibule on magnetic resonance imaging (MRI) might be a high-risk factor for complications in cases that are candidates for stapes surgery. OBJECTIVE Pre-operative detection of EH could be valuable in cases that are candidates for stapes surgery to prevent unpredictable complications following surgery. Pre-operative MRI findings and post-operative findings following stapes surgery were compared to evaluate the efficacy of such MRI evaluation for the management of cases with otosclerosis. SUBJECTS AND METHODS Sixteen cases who underwent pre-operative evaluation by 3T MRI performed 4 h after intravenous injection of gadolinium and stapes surgery for otosclerosis were recruited. Imaging data concerning the degree of EH in the vestibule and cochlea were compared with post-operative clinical findings for all cases. RESULTS Mild EH in the cochlea or the vestibule was observed in eight ears and one ear, respectively, whereas one ear showed significant EH both in the cochlea and the vestibule. The post-operative course was uneventful in 12 of 14 cases with no EH in the vestibule, and the other two cases had a short period of dizziness, but two cases with EH in the vestibule had a long period of dizziness.

Abstract
CONCLUSION All definite Meniere's disease (MD) had endolymphatic hydrops (EH) at least in the cochlea or the vestibule. Symptoms of MD may appear after formation of EH. It is assumed that the probability of immediate progression to bilateral MD from unilateral MD is very low in patients without EH on the non-affected side. OBJECTIVE To evaluate the EH on both sides in patients with unilateral and bilateral MD, and to investigate factors with progression to bilateral MD including the degree of EH, hearing level, and the duration of MD. PATIENTS AND METHODS The study included 29 patients with unilateral definite MD and 12 patients with bilateral definite MD. The endolymphatic space size was visualized by using 3-Tesla magnetic resonance imaging. RESULTS All patients with unilateral and bilateral MD had significant or mild EH at least in the cochlea or the vestibule on the affected side. On the non-affected side, EH was not observed at all in eight patients, but asymptomatic EH was observed in the cochlea in 14 patients and in the vestibule in 16 patients. There was no relationship between the EH on the non-affected side and the duration of MD.

Abstract
BACKGROUND It has been reported that periodontitis is associated with Alzheimer's disease. However, the association between paranasal sinusitis and Alzheimer's disease has not been studied, although olfactory dysfunction frequently precedes the progress of dementia or Alzheimer's disease. METHODS We studied 783 patients (283 men, 500 women; mean age 77.0 ± 7.9 years) who visited the Center for Comprehensive Care and Research on Memory Disorders, National Center for Geriatrics and Gerontology, and 2139 control subjects who participated in a population-based study conducted by the National Institute for Longevity Sciences - Longitudinal Study of Aging (NILS-LSA) in Japan. Sinusitis was evaluated using magnetic resonance imaging (MRI) according to the Lund-Mackay scoring system. A sinusitis score of ≥ 4 was classified as positive and a score of ≤ 3 was classified as negative. RESULTS The prevalence of positive sinusitis was 6.3% in patients with a mini-mental state examination (MMSE) score of < 24 (n = 507), and 5.7% in patients with Alzheimer's disease (n = 280). The rate of positive sinusitis was7.2% in the control group. The prevalence of sinusitis was not significantly different between normal controls and patients with dementia or Alzheimer's disease after adjustments for age and sex. The rate of positive sinusitis was higher in male than in female subjects in both groups. CONCLUSION The prevalence of sinusitis in patients with Alzheimer's disease or dementia was not higher than in the general population.

Abstract
CONCLUSION This study revealed that endolymphatic hydrops (EH) reduced in some cases with Ménière's disease (MD) treated conservatively. It appears that the EH reduction was associated with improvement of the clinical symptoms. OBJECTIVES The relationship between the degree of EH and clinical symptoms is not clear at present. The purpose of the present study was to investigate the time course of the relationship in patients with MD treated conservatively. PATIENTS Twelve patients with MD treated conservatively for more than 1 year in a university hospital. METHODS Twenty ears of 12 patients with MD treated conservatively were evaluated. The presence or absence of vertigo, tinnitus and ear fullness was confirmed when magnetic resonance imaging (MRI) was performed. Using a 3 T MRI scanner, three-dimensional fluid-attenuated inversion recovery (3D-FLAIR) MRI was performed 2 or 3 times 24 hours after intra-tympanic gadolinium injection or 4 hours after intravenous gadolinium injection. RESULTS In the three ears in which the symptoms alleviated, EH was reduced in two ears, but EH was reduced in only one of 17 ears in which the symptoms did not alleviate. The Fisher exact test revealed that EH reduction occurred more frequently in ears with alleviation of the symptoms (p < 0.05).

Abstract
AIM Hearing loss is a risk factor for the progression of dementia. Cognitive improvement is occasionally found after removal of cerumen impaction. Because patients with dementia do not usually complain about cerumen impaction, detection methods are important. The present study aimed to investigate whether cerumen impaction is observable using brain magnetic resonance imaging. METHODS Participants were six patients whose hearing level improved 15 dB or more unilaterally or bilaterally after the removal of cerumen impaction. A radiologist who was blind to the impaction side and whether magnetic resonance imaging scans were taken before or after impaction removal classified cerumen impaction as positive, negative or unclear. RESULTS Three ears classified as impaction positive and five ears classified as impaction negative corresponded accurately to the presence or absence of cerumen impaction. Among four ears classified as unclear, two did and two did not have cerumen impaction. CONCLUSION Careful examination of the external ear canal on brain magnetic resonance imaging can be used to detect cerumen impaction.

Abstract
Conclusion An epidemiological survey of hospitals and private clinics in Japan regarding idiopathic sudden sensorineural hearing loss (SSNHL) revealed that the incidence of SSNHL was 60.9 per 100 000 population. There were more females than males in the younger generation. Objective The incidence of SSNHL varies largely by country. Because the Japanese criteria for diagnosing SSNHL have changed in accordance with those widely used in other parts of the world, a clinicoepidemiological study was undertaken using the new criteria. Methods Ehime, Aichi, and Iwate Prefectures were selected from the western, central, and northeastern regions of Japan, respectively. The subjects for this study were patients who suffered SSNHL between April 1, 2012 and March 31, 2013. Questionnaires were mailed to all hospitals and private clinics in which ENT doctors were working. Initial and final audiograms were requested for 10% of the patients. Results In all, 78 of 90 hospitals (87%) and 303 of 407 private clinics (74%) responded. It was reported that 1663 patients visited hospitals and 3090 patients visited only private clinics. It was estimated that 6205 SSNHL patients visited hospitals or private clinics in 1 year from a population of 10 145 000. Also, 23% of patients suffered acute low-tone SNHL (female to male ratio; 3:1 in definite cases).

Abstract
CONCLUSION The results indicate that oral administration of azithromycin (AZM) is equivalent to intravenous administration of cefazolin (CEZ) for preventing surgical site infection (SSI) in patients undergoing tonsillectomy, and should be used as cost-effective antimicrobial prophylaxis. OBJECTIVE Staphylococcus aureus, Streptococcus spp., and pharyngeal anaerobes have been described as major pathogens causing SSI in transpharyngeal operations such as tonsillectomy. The purpose of this study was to explore whether administration of AZM, an oral antimicrobial agent, might be equivalent to intravenous administration of a first-generation cefem antimicrobial agent for preventing SSI in patients undergoing tonsillectomy. METHODS Patients undergoing tonsillectomy were divided into an AZM-treated group and a CEZ-treated group, for intergroup comparison of responses. AZM was administered once orally, 2 days before the operation, whereas patients in the CEZ-treated group received CEZ intravenously 30 min before the operation, 4 h postoperatively, and then twice daily for 3 consecutive days beginning the day after the operation. RESULTS There were no significant intergroup differences in mean duration of hospitalization after the operation, incidence of postoperative hemorrhage, postoperative analgesic effect, or hematologic/blood biochemical findings. The incidence of postoperative fever was significantly lower in the AZM-treated group. Diarrhea occurred as an adverse drug reaction in the AZM-treated group, but no clinically significant adverse reactions were noted.

Abstract
Patients with MPO-ANCA related angitis sometimes experience the onset of sonsorineural hearing loss and facial palsy. The main aim of this study was to investigate the relationship between the inflammation in the inner ear and sensorineural hearing loss, or between the inflammation of the facial nerve and facial nerve palsy in patients with MPO-ANCA related angitis. From 2007 to 2011, the inner ear was evaluated in 16 ears from 8 patients with MPO-ANCA related angitis with 3D-FLAIR MRI. In 12 ears of the 16 ears the onset of sensorineural hearing loss was noted, and the signal intensity ratio (SIR) in the cochlea was 0.62 +/- 0.15 on pre-enhancement 3D-FLAIR MRI, and 0.97 +/- 0.5 on post-enhancement. These SIR values were significantly higher than the SIR of non-sensorineural hearing loss patients. The onset of facial palsy was noted in 9 of 16 sides and the facial nerve SIR was 0.83 +/- 0.23 on post-contrast 3D-FLAIR MRI. The SIR in the facial nerve of facial nerve palsy patients was higher than non-facial palsy patients. The conclusion is that sensorineural hearing loss and facial palsy in patients with MPO-ANCA related angitis occurred due to strong inflammation in the cochlea or facial nerve. 3D-FLAIR MRI made this pathology clear.

Abstract
CONCLUSION In patients with poorly controlled diabetes mellitus (DM), hearing disturbance was associated with renal dysfunction and diabetic neuropathy, represented by decreases in median nerve compound action potential amplitude. METHODS The evaluation was conducted using 43 subjects who were hospitalized for the purpose of DM education. The mean age was 58.1 years (range 21-82 years). The mean HbA1c was 9.5%. The mean DM duration was 11.0 years. Renal function, retina condition, and nerve conduction were evaluated in relation to DM complications (nephropathy, retinopathy, and neuropathy). Nerve conduction studies were used to obtain detailed information on the condition of the peripheral nerves. After otological inspection, pure-tone audiometry, auditory steady-state response (ASSR), and distortion-product otoacoustic emissions (DPOAEs) were measured. Stepwise multiple linear regression was used to analyze the results in the better ear and worse ear. RESULTS Decreases in median nerve compound action potential amplitude were associated with deterioration in pure-tone audiometry and ASSR. Diabetic neuropathy, creatinine clearance, diabetic nephropathy, and retinopathy were related to hearing in ASSR and/or DPOAEs.

Abstract
Objectives: Evaluate vascular activity in ears with otosclerosis by intraoperative measurement of blood flow using laser-Doppler flowmetry, and compare the data with densitometry on computed tomography (CT). Methods: Thirty-nine ears from patients who underwent surgery for otosclerosis were assessed in the present study. The subjects were divided into the fenestral (29 ears) and the retrofenestral (10 ears) groups by CT. Ratios of bone density in the area anterior to the oval window (AOW) or the promontory (PT) near the round window niche to that of the basis labyrinthine otic capsule were calculated on CT images. Measurements of blood flow were performed with a laser-Doppler flowmeter at the two corresponding areas evaluated by CT. Results: In both groups, relatively young subjects with high blood flow values in the AOW or PT had rather low ratios of bone density in the corresponding areas. In contrast, old subjects with low ratios of bone density showed low blood flow values in the same areas. In the retrofenestral group, subjects with high blood flow values in the PT showed low blood flow values in the AOW, but their ratios of bone density were similarly low in both areas. Conclusions: Blood flow varied and did not correlate with CT densitometry. Measurement of blood flow by laser-Doppler flowmetry could yield useful information to evaluate the progress of vascular activity.

Abstract
Objectives: Human temporal studies have shown that endolymphatic hydrops (EH) is accompanied by otosclerosis, which is a risk factor for complications after stapes surgery. Recently, visualization of EH has become possible using magnetic resonance imaging (MRI) with contrast agents. The presence of EH in cases with otosclerosis was investigated by MRI to prevent complications following stapes surgery. Methods: Sixteen ears from nine cases diagnosed as having otosclerosis were evaluated by 3-Tesla MRI examinations taken 4 h after intravenous gadolinium injection. More than half of the ears showed mixed hearing loss and were suspected to have cochlear otosclerosis. Imaging data were compared with clinical findings in all ears and postoperative symptoms in ears undergoing surgery. Results: Varying degrees of EH were observed in 14 of the 16 ears. Episodes of acute sensorineural hearing loss or vertigo occurred in 4 ears with severe EH in the cochlea and 3 ears with severe EH in the vestibules. Overall, 12 of 14 ears with EH did not undergo stapes surgery. Ears without EH showed no postoperative complications, but one ear with mild EH in the vestibule showed severe vertigo following the surgery. Conclusions: The presence of EH in cases with otosclerosis was clearly visualized, and the degree of EH was correlated with the clinical findings in most patients. Such preoperative MRI evaluation could provide useful information to prevent complications following stapes surgery.

Abstract
CONCLUSION Using magnetic resonance imaging (MRI), endolymphatic hydrops could be visualized on both sides after intratympanic (IT) injection of gadolinium contrast agents (Gd) in one symptomatic ear and subsequent intravenous (IV) Gd injection. The MRI revealed a difference of intracochlear Gd distribution between the IT injection side and the contralateral IV side. OBJECTIVES Although the IT method allows greater enhancement of the perilymph, many patients feel reluctance in receiving the IT injection in asymptomatic ears. We attempted to evaluate endolymphatic space size on both sides without the IT injection in asymptomatic ears. METHODS In 10 patients with Meniere's disease, MRI was performed 24 h after the IT Gd injection in one symptomatic ear and 4 h after the IV Gd injection. The signal intensity of Gd in the basal and apical turns of the cochlea was evaluated. RESULTS The signal intensity in the scala tympani of the basal turn of the cochlea was 1.70 ± 0.60 on the IT + IV side and 0.42 ± 0.10 on the contralateral (IV) side. Gd was distributed uniformly in the scala tympani in the cochlea on the IV side, whereas it was strongly localized in the basal turn on the IT + IV side.

Abstract
Folate metabolism is essential for cellular functioning. Despite extensive research on the roles of folate-metabolism-related gene polymorphisms in the pathophysiology of many diseases, such as cardiovascular disease, cancers, and sudden sensorineural hearing loss, little is known about their association with Ménière's disease (MD). The aim of this study was to investigate the effect of methylenetetrahydrofolate reductase (MTHFR) gene polymorphisms (C677T and A1298C) on the risk of MD in a Japanese population. We examined the C677T and A1298C (rs1801133 and rs1801131) polymorphisms in the MTHFR gene and compared them between 1946 adults (986 men and 960 women) participating in the National Institute for Longevity Sciences Longitudinal Study of Aging and 86 cases of MD. A multiple logistic regression was performed to obtain odds ratios (ORs) for the risk of MD regarding the MTHFR polymorphisms before (model 1) and after (model 2) adjustment for age and sex factors. The OR of MTHFR C677T for the risk of MD was 0.669 (95% confidence interval [CI], 0.479-0.934) in model 1 and 0.680 (95% CI, 0.484-0.954) in model 2. In contrast, the OR of MTHFR A1298C for the risk of MD was 1.503 (95% CI, 1.064-2.123) in model 1 and 1.505 (95% CI, 1.045-2.167) in model 2. Our results imply that the MTHFR C677T and A1298C polymorphisms are associated with the risk of MD.

Abstract
CONCLUSION Our study showed that patients with atypical Meniere's disease had endolymphatic hydrops (EH) in both the cochlea and the vestibule. Using an imaging method, we provide evidence that atypical Meniere's disease is a true variant of classic Meniere's disease. OBJECTIVES The aim of present study was to investigate images of the endolymphatic space in patients with atypical Meniere's disease (cochlear and vestibular Meniere's disease). METHODS Sixty-four patients divided into two groups were enrolled in this study. The first group included 36 patients who had fluctuating hearing loss without vertigo, as candidates for cochlear Meniere's disease (CMD). The second group included 28 patients who had recurrent vertigo without hearing loss, as candidates for vestibular Meniere's disease (VMD). The patients underwent 3 T magnetic resonance imaging (MRI) after injection of gadolinium enhancement medium intratympanically or intravenously. We evaluated EH using MRI. RESULTS Of 56 ears (36 patients) with CMD, 38 showed EH in the cochlea and 44 showed EH in the vestibule. Of 56 ears (28 patients) with VMD, 29 showed EH in the cochlea and 47 showed EH in the vestibule. The VMD group had a significant vestibular predominance in EH distribution whereas the CMD group showed no significant regional predominance of EH.

Abstract
CONCLUSION Persistent obstructive sleep apnoea syndrome (OSAS) occurs in approximately 20% of normal-weight children after adenotonsillectomy (T&A) and, in nearly 70% of them, it is caused by adenoid regrowth. Patients with severe or moderate OSAS showed a high incidence of persistent disease even after T&A. Allergic disease, severity and large adenoid size are associated with adenoid regrowth and persistent disease. OBJECTIVES To investigate factors contributing to persistent OSAS and adenoid regrowth after T&A in normal-weight children. METHODS This was a prospective, observational study at a single institute and involved 49 normal-weight children with severe or moderate OSAS (apnoea-hypopnoea index, AHI, ≥ 5) who underwent T&A. Background information, nasal endoscopic data and pre- and postoperative polysomnographic data were collected. A third polysomnography (PSG) was performed 1.5 year postoperatively in children who subsequently developed symptoms of sleep disturbance. RESULTS Thirteen children (27%, 13/49) were symptomatic 1.5 years after T&A. Allergic rhinitis (38.5% vs 11.1%, p = 0.03) and allergic disease (69.2% vs 30.6%, p = 0.02) were seen more frequently in these children. A third PSG confirmed persistent disease (AHI ≥ 5) in nine children (18.4%, 9/49). Six children (12.2%, 6/49) were diagnosed as having adenoid regrowth and three (6.1%, 3/49) underwent revision adenoidectomy.

Abstract
The etiologies of idiopathic sudden sensorineural hearing loss (SSNHL) and Ménière's disease remain unclear. Recently, accumulating evidence has demonstrated that oxidative stress is related to the pathology of inner ear disease. Because genetic factors may contribute partly to the etiologies of SSNHL and Ménière's disease, we investigated the associations between genetic polymorphisms located in oxidative stress response genes and susceptibility to SSNHL and Ménière's disease. We compared 84 patients affected by SSNHL, 82 patients affected by Ménière's disease, and 2107 adults (1056 men and 1051 women; mean age, 59.2 years; range, 40-79 years) who participated in the National Institute for Longevity Sciences, Longitudinal Study of Aging. Multiple logistic regression was used to calculate odds ratios for SSNHL and Ménière's disease in individuals with polymorphisms in the genes glutathione peroxidase 1 (GPX1) (Pro198Leu, rs1050450), paraoxonase 1 (PON1) (Gln192Arg, rs662; and Met55Leu, rs854560), PON2 (Ser311Cys, rs7493), and superoxide dismutase 2 (SOD2) (Val16Ala, rs4880), with adjustment for age and gender. No significant differences in the distribution of the genotypes at these polymorphisms were observed among individuals with SSNHL and Ménière's disease and controls. No significant risk for SSNHL and Ménière's disease was observed in the additive genetic model, regardless of moderating variables. The C allele of SOD2 (rs4880) was more frequent in Ménière's disease cases with a hearing level over 50 dB compared with cases with a hearing level below 50 dB, suggesting that this polymorphism is associated with progression of a hearing loss in Ménière's disease. In conclusion, no significant associations between the polymorphisms of GPX1, PON1, PON2, and SOD2 and risk of SSNHL and Ménière's disease were observed in this Japanese case-control study.

Abstract
Sudden sensorineural hearing loss (SSNHL) is one of the most common diseases encountered by otolaryngologists; however, the etiology is unclear. The aim of this study was to assess the association between SSNHL and polymorphism of complement factor H (CFH) Y402H, which is implicated in age-related macular degeneration. We conducted a case-control study, in which the cases were 72 SSNHL patients and the controls were 2161 residents selected randomly from the resident register. The odds ratio (OR) for SSNHL risk was determined using the additive-genetic model of CFH Y402H polymorphism. The OR for SSNHL risk was 1.788 (95% confidence interval [CI]: 1.008-3.172) with no adjustments and 1.820 (CI: 1.025-3.232) after adjusting for age and sex. Of the three lifestyle-related diseases hypertension, dyslipidemia, and diabetes, only diabetes was significantly associated with SSNHL risk. We classified both the controls and SSNHL patients into those with or without diabetes, and the OR for SSNHL risk was 6.326 (CI: 1.885-21.225) in diabetic subjects and 1.214 (CI: 0.581-2.538) in nondiabetic subjects. We conclude that CFH Y402H polymorphism and SSNHL risk are significantly related, and that diabetic CFH Y402H minor allele carriers may be susceptible to SSNHL.
