Background Tinnitus is a common condition in adults; however, the pathophysiology of tinnitus remains unclear, and no large population-based study has assessed associated risk factors. The aim this was to analyze prevalence factors tinnitus. Methods We conducted cross-sectional using data from Korea National Health Nutrition Examination Survey, with 19,290 participants ranging age 20 98 years old, between 2009 2012. investigated questionnaire analyzed various possible simple multiple...
The functional status of central neural pathways, in particular their susceptibility to plasticity and reorganization, may influence speech performance deaf cochlear implant users. In this paper, we sought determine how brain metabolic activity measured before implantation relates outcome, that is, perception. 22 prelingually children between 1 11 years, correlated preoperative glucose metabolism as by F-18 fluorodeoxyglucose positron emission tomography with individual perception assessed 3...
On occasion, outbreaks of infection with adenovirus types 3, 7, and 21 cause severe lower respiratory tract infections (LRTIs) in children. From 1990 to 1998, all cases LRTI due at the Seoul National University Children's Hospital, Seoul, Korea, were reviewed. Adenoviruses recovered from nasal aspirate specimens 87 (5.9%) 1472 children LRTI. The principal serotypes type 2 (13 [15%] strains), 3 [15%]), 7 (36 [41%]). Of infections, 62 (71%) occurred <2 years age, 81 (94%) <5 age. Infections...
Hearing thresholds provide essential information and references about the human auditory system. This study aimed to identify changing trends in distributions of hearing threshold levels across ages by comparing International Organization for Standardization (ISO) 7029 newly available data after publishing ISO 7029. To compare 7029, four country-specific datasets that presented average under conditions similar were utilized. For frequencies between 125 Hz 8,000 Hz, deviations values from...
Cochlear implantation is an effective technique for restoring hearing in the profoundly deaf. Although cochlear implants are a therapeutical success, huge performance variability speech comprehension observed after implantation. The reason this remains incompletely understood 20 years of clinical practice and basic research. Which patients going to respond well why unresolved question. duration auditory deprivation plays important role, currently main predictor success children; basically,...
Cytomegalovirus (CMV) colitis can contribute to an unfavorable outcome of acute severe ulcerative (ASUC). The purpose this study was evaluate the clinical outcomes ASUC according CMV status and identify risk factors for in patients with ASUC. We retrospectively analyzed from 2011 2014 criteria Truelove Witts. diagnosed by histopathological and/or immunohistochemical analysis tissue samples. were investigated assessed using rate rescue therapy colectomy. Of 149 ASUC, 50 (33.6%) colitis....
Background: Diagnosis of benign paroxysmal positional vertigo (BPPV) depends on the accurate interpretation nystagmus induced by tests. However, difficulties in interpreting eye-movement often can arise primary care practice or emergency room. We hypothesized that use machine learning would be helpful for interpretation. Methods: From our clinical data warehouse, 91,778 videos from 3467 patients with dizziness were obtained, which three-dimensional movement was annotated four otologic...
<h3>Importance</h3> A connection between Meniere disease (MD) and migraine has been proposed, but the temporal association remains unknown. <h3>Objective</h3> To examine bidirectional of MD with migraine. <h3>Design, Setting, Participants</h3> This case-control study included participants 40 years or older from Korean National Health Insurance Service Screening Cohort 2002 to 2015. <h3>Main Outcomes Measures</h3> total 6919 patients were matched 27 676 control without for age, sex, income,...
AbstractObjective – To evaluate the long-term speech perception of cochlear implantees and to compare developing auditory performance patterns prelingual children postlingual deaf adults. Material Methods Twenty-nine prelingually 17 postlingually adults who had been followed up for 4 years were included in study. Speech ability was assessed by means vowel consonant confusion tests Korean version Central Institute Deafness (K-CID) test (performed without visual cues). The results analyzed at...
Background and aims: No previous large-scale studies have evaluated the prognosis of ulcerative colitis (UC) over a period three decades in non-Caucasian population. The aims this study were to update current information on natural course UC sizable cohort Korean patients evaluate changes treatment paradigms time. Methods: We retrospectively analyzed 2802 who visited Asan Medical Center. divided subjects into groups based year diagnosis (cohort 1: 1977–1999; 2: 2000–2006; 3: 2007–2013)....
Tinnitus in children and adolescents is known to be as common adults. However, tinnitus this young population often overlooked, a large population-based study designed adjust for various risk factors lacking.A cross-sectional was conducted using data from the Korea National Health Nutrition Examination Survey, with 3047 participants aged 12 19 years, 2008 through 2011. We investigated prevalence by questionnaire analyzed of three types: personal, otologic, parental factors.The 17.7%,...
Abstract Post‐lingual deafness induces a decline in the ability to process phonological sounds or evoke representations. This is paralleled with abnormally high neural activity right posterior superior temporal gyrus/supramarginal gyrus (PSTG/SMG). As this plasticity negatively relates cochlear implantation (CI) success, it appears important understand its determinants. We addressed neuro‐functional mechanisms underlying maladaptive phenomenon using behavioral and functional magnetic...
Korean Clinical Practice Guidelines: Otitis Media in ChildrenAcute otitis media (AOM) and with effusion (OME) are common infections children, their diagnosis treatment have significant impacts on the health of children costs providing national medical care.In 2009, Otologic Society organized a committee composed experts field otolaryngology, pediatrics, family medicine to develop clinical practice guidelines (CPG) for goal meeting regional social needs Korea.For this purpose, adapted...
Objectives The objective of our study was to establish whether increased lipid profiles and obesity affect the prevalence prognosis sudden sensorineural hearing loss (SSNHL). Methods This a case-controlled with longitudinal design. According criteria, 324 patients SSNHL were included in this study. To manage potential covariates, 972 subjects normal from Korean National Health Nutrition Examination Survey matched as control group according their propensity scores. Age, level total...
Crohn's disease (CD) is a chronic idiopathic inflammatory bowel involving the whole gastrointestinal tract. TNFSF15 has been proved as susceptibility gene for CD, but there are few reports about association between single nucleotide polymorphisms (SNPs) and clinical course of CD.To investigate genotypes CD in Koreans.A total 906 patients having genotype data information were recruited from registry database tertiary referral center. The five SNPs (rs4574921, rs3810936, rs6478108, rs6478109,...
We aimed to estimate the effects of various risk factors on hearing level in Korean adults, using data from Korea National Health and Nutrition Examination Survey. examined 13,369 participants collected between 2009 2011. Average thresholds at low (0.5, 1, 2 kHz) high frequencies (3, 4, 6 kHz), were investigated accordance with known via multiple regression analysis featuring complex sampling. additionally evaluated 4,810 who completed a questionnaire concerned different types noise...
Potentially neuroprotective effects of CI use were studied in 22 children with single sided deafness (SSD). Auditory-evoked EEG confirmed strengthened representation the intact ear ipsilateral auditory cortex at initial activation early-onset SSD (n = 15) and late-onset occurring suddenly later childhood/adolescence 7). In SSD, hearing decreased chronic experience expected lateralization to contralateral from increased longer daily use. abnormally high activity reduced, but responses deaf...
Objectives. We evaluated changes in income levels a hearing-impaired population.Methods.
