RESUMO
In this comprehensive review, we discuss recent updates on tinnitus evaluation and treatment. Tinnitus evaluation commences with comprehensive medical history taking and audiological evaluation, which can provide valuable insight into the nature and extent of auditory disturbances. Additionally, tinnitus evaluation includes investigation of psychosomatic comorbidities to determine the intricate interplay between psychological factors and tinnitus perception. Various therapeutic approaches are available to minimize the burden of tinnitus. Cognitive behavioral therapy reshapes negative thought patterns and behaviors that are closely associated with tinnitus-induced distress. Acceptance and commitment therapy fosters mindfulness and value-aligned actions to address emotional effects. Tinnitus retraining therapy combines counseling and sound therapy for habituation. Tailor-made notched music therapy offers customized auditory experiences for symptom relief. Hearing aids and cochlear implants compensate for hearing loss and associated stress. Both neuromodulation and neurofeedback may be potentially useful. The role of pharmacotherapy and dietary supplements remains uncertain. Physiotherapy and head-neck manipulation relieve tinnitus associated with orofacial factors. Virtual reality, smartphone applications, and photobiomodulation may serve as novel therapeutic avenues. Although promising interventions are available, further research is warranted to confirm their effectiveness and long-term effects.
RESUMO
Background and Objectives@#The guidelines for cochlear implantation (CIs) are expanding, and the number of CI procedures performed on the elderly is increasing. The purpose of this study was to analyze the results and safety of cochlear implantation in the elderly, as well as to evaluate the predictive factors on CI outcomes. @*Subjects and Methods@#The study included 56 patients aged ≥40 years, who received CIs between 2009 and 2020. They were divided into two groups: 27 younger adults (40-64 years) and 29 elderly (>64 years). The study compared their pre- and postoperative speech perception and category of auditory performance (CAP) scores, surgical complications, and hospitalization periods. It also evaluated associated factors in the elderly group by examining categorical and continuous variables and postoperative CAP score. @*Results@#There was a significant improvement in speech recognition tests (both word and sentence) and CAP scores in both groups compared to the pre-implantation scores (p<0.001). Postoperative results were slightly lower in the elderly group than in younger adults for sentence recognition and CAP scores, except for word recognition. No significant associated factors were found on postoperative CAP scores, except for etiology. Postoperative CAP significantly improved in the sudden hearing loss group compared to the groups with other etiologies (p=0.045). The elderly group had more comorbidities than that in the younger adult group (p=0.026), but there were no significant differences in postoperative complications and hospitalization periods. @*Conclusions@#While speech recognition and CAP scores were relatively lower in the elderly group compared to the younger adults, the elderly group showed significant improvements in audiological results after CI. Moreover, CI was safe and well tolerated in elderly patients.
RESUMO
Background@#To investigate the actual rate and quality of cardiac rehabilitation (CR) participation in South Korea and its short-term impact on clinical outcomes after acute coronary syndrome (ACS). @*Methods@#Data, including confirmed ACS diagnosis, socio-demographics, comorbidities, clinical outcomes, and CR claim codes, were collected from the Korean National Health Insurance Service claims database and compared between the CR and non-CR groups. @*Results@#Overall, 102,544 patients were included in the study, of which only 5.8% attended CR. Regarding testing, 83.6% of CR patients performed the cardiopulmonary exercise test, but follow-up testing was infrequently performed; in addition, 53.1% of them participated in an electrocardiogram monitoring exercise, but over half participated in only one session.After 1:1 propensity score matching, post-ACS cardiovascular events were significantly lower in the CR group than in the non-CR group. The cumulative 3-year hazard ratio for all-cause death was 0.612 (95% confidence interval [CI], 0.495–0.756), recurrent ACS was 0.92 (95% CI, 0.853–0.993), CR readmission was 0.817 (95% CI, 0.768–0.868), and major adverse cardiovascular events (MACE) was 0.827 (95% CI, 0.781–0.874) in the CR group. CR was associated with a significant dose-response effect on MACE, with a reduction in incidence from 0.854 to 0.711. @*Conclusion@#The actual rate of CR participation in South Korea remains low, and participation quality was not outstanding despite National Health Insurance coverage.Nevertheless, the impact of CR on cardiovascular outcomes after ACS was significantly superior. Efforts to increase CR participation should be increased by establishing new CR facilities and strategies to resolve associated barriers.
RESUMO
We report a case of a pseudoaneurysm secondary to skull base osteomyelitis (SBO) in an 82-year-old female. The patient was hospitalized with an acute episode of bleeding from the right ear, which persisted despite packing placed in the ear. We suspected bleeding from the internal carotid artery (ICA) and performed angiography, which revealed a pseudoaneurysm that presumably developed secondary to invasion of the wall of the petrous segment of the right ICA, and the patient underwent emergency coil embolization. Bleeding from the ear recurred a week later, and we performed repeat angiography, followed by embolization and deployment of multiple stents at the site of the pseudoaneurysm, which controlled the bleeding. Clinicians should be mindful of a pseudoaneurysm as a rare complication of SBO, following the spread of infection to adjacent soft tissues or vessels. A pseudoaneurysm should be considered in the differential diagnosis in patients with recurrent epistaxis or bleeding from the ears in addition to cranial nerve symptoms, and this condition warrants urgent evaluation.
RESUMO
Clinicians and healthcare decision-makers conduct their clinical practice based on the results of clinical trials. However, some health problems remain unresolved; in such cases, further research is required. To ensure reliable research results, it is important to understand the study design and conduct well-designed clinical trials. Many study designs can be chosen within the two broad categories of observational and interventional. Clinical studies have a variety of designs, including case series, case-control, cross-sectional, and prospective and retrospective cohort studies. Well-designed clinical studies can clarify important differences between treatment options and provide data on long-term drug efficacy and safety. Interpreting the results of clinical trials can be difficult because weaknesses in research design, data collection methods, analytic methods, and reporting can compromise their value and usefulness. However, although randomized controlled trials are limited owing to ethical and practical issues, they are optimal for investigating the effects of therapy and establishing causality. Here we present an overview of different clinical research designs and review their advantages and limitations.
RESUMO
Syphilis is a sexually transmitted disease caused by Treponema pallidum, which can invade various organs. Syphilis can also cause otologic symptoms such as hearing impairment, tinnitus or dizziness and these otologic symptoms can occur at any stage of syphilis and can be associated with neurosyphilis. We report here a case of rapid progressive neurosyphilis showing hearing impairment in a patient with ankylosing spondylitis. He was treated with anti-interleukin 17A monoclonal antibody. Since syphilis is one of the causes of reversible sensorineural hearing loss and syphilis infection with immunosuppression can cause progressive hearing loss if patients in immunomodulatory therapy have sensorineural hearing loss, the possibility of syphilis should be considered.
RESUMO
The gut microbiome closely interacts with the host, and it has a major influence on drug response. Many studies have reported the possible microbial influences on drugs and the possible influences of drugs on the microbiome. This knowledge has led to a better understanding of intra- and inter-individual variabilities in clinical pharmacology. For a more precise understanding of the complex correlation between the microbiome and drugs, in this review, we summarized the current knowledge on the interactions between the gut microbiome and drug response. Moreover, we suggest gut microbiome-derived metabolites as possible modulators of drug response and recommend metabolomics as a powerful tool to achieve such understanding.
RESUMO
The Center for Children’s Foodservice Management periodically visited children’s foodservice facilities forhygiene, safety and nutrition management, and the ‘HSQ (Hygiene Safety Quotient) and NQ (NutritionQuotient) Management Web & App Program’ was developed and applied to improve the health, safety, andnutrition management status of children’s foodservice facilities. The HSQ is a comprehensive hygiene andsafety index consisting of six categories from the hygiene and safety checklist for children’s foodservice facilitiesprovided by the Ministry of Food and Drug Safety. The NQ is a nutrition index for foodservice facilitiesconsisting of five categories from the nutrition checklist. First, this program can be used to efficientlyunderstand the actual conditions of children’s foodservice. Foodservice facilities are provided with the resultreport prepared by the center without restrictions on time or place. Second, it can be used as “a channel forcomfortable communication with foodservice facilities”. Foodservice facilities are provided with a route wherequestions and resolutions can be communicated to the center. Third, it is easy to compare and review the resultsof foodservice facilities by institution and number of visits while downloading the results data at thesame time, as the result report is written based on hygiene, safety, and nutrition visits. Through such programs,it is believed that standardized work and integrated management will improve the work efficiency ofthe center’s employees. It is also thought that these programs will promote healthier life-styles in children byestablishing a safe food environment for children’s foodservice.
RESUMO
Background@#Although the consumption of vitamin beverages has increased because of the recent interest in health and beauty, guidelines addressing appropriate consumption habits are lacking. Thus, the aim of this study was to investigate the erosive potential of several vitamin beverages and to propose guidelines for the appropriate intake of these drinks. @*Methods@#Five vitamin beverages were selected after a pre-investigation of the current beverage market. Coca-Cola and mineral water were selected as the control beverages. The pH of the beverages was measured with a calibrated pH meter, and the titratable acidity (TA) was determined by using 1 M sodium hydroxide to reach pH 5.5 (TA5.5) and 7.0 (TA7.0). The screening method suggested by the International Organization for Standardization was used to measure pH variation (pH) by using an under-saturated hydroxyapatite solution to determine the difference between the initial and final pH of the screening solution. All measurements were performed in triplicate. @*Results@#All vitamin beverages tested in this study exhibited a low pH (2.53∼2.99), similar to Coca-Cola, which is known to be a highly acidic beverage. The highest TA5.5 and TA7.0 values of the vitamin beverages were 7.03 ml and 8.81 ml, respectively. The largest change in pH determined by using the screening solution was found in Bacchus D (pH 1.44±0.05). The mean pH of the vitamin beverages was 1.12±0.29, which was higher than that of Coca-Cola (positive control, pH 0.58±0.05). @*Conclusion@#Vitamin beverages exhibited an erosive potential capable of damaging enamel surfaces. Therefore, the frequency of vitamin beverage intake should be limited, and individuals consuming these drinks should try to restore normal oral pH as quickly as possible.
RESUMO
Idiopathic intracranial hypertension (IIH) is a disorder that commonly occurs in obese young women of childbearing age and is characterized by symptoms such as pulsatile tinnitus, dizziness, headache, nausea, vomiting, and visual loss without any structural or vascular abnormalities in the intracranial cavity. We recently experienced a case of a 33-year-old obese woman who presented with right-sided pulsatile tinnitus, which is an early symptom for IIH. The patient was successfully treated with weight reduction and carbonic anhydrase inhibitor (acetazolamide). Pulsatile tinnitus requires thorough diagnosis and examination because it can be cured if the anatomical or functional cause is identified and treated. When obese women of childbearing age present with pulsatile tinnitus at the otorhinolaryngology outpatient department, treatment for IIH should be initiated after appropriate examination and diagnosis as pulsatile tinnitus may be the only symptom for IIH.
RESUMO
Background and Objectives@#The optimal dose or type of systemic steroid for treating idiopathic sudden sensorineural hearing loss (ISSNHL) is unclear. Herein, we compare the efficacy of three steroid treatment protocols.Subjects and Method We reviewed the medical records of 140 adult ISSNHL patients from a tertiary medical center. The patients were divided into three groups based on their treatment regimen: Group 1 received intravenous 10 mg/day dexamethasone combined with intratympanic (IT) steroid injection, followed by prednisolone for 5 days after discharge; Group 2 received 10 mg/day dexamethasone for 5 days, followed by 5 mg/day for 5 days over a 10-day hospitalization period; and Group 3 received 10 mg/day dexamethasone combined with IT steroid injection during a 5-day hospital stay, followed by 5 mg/day dexamethasone for 5 days after discharge. The hearing thresholds were measured using an automatic audiometer at 0.5, 1, 2, 3, 4, and 8 kHz. Hearing recovery on Day 90 was categorized according to Siegel’s criteria. @*Results@#Univariate and multivariate analyses showed that patients in Group 3 had the lowest hearing thresholds, and the best results for speech reception threshold and speech discrimination scores. The impact of favorable thresholds in Group 3 was better among patients with a baseline average hearing threshold of ＜70 dB. Complete recovery was more likely in Group 3 than in the other groups, based on the odds ratios. @*Conclusion@#Administration of dexamethasone-based systemic steroid combined with IT steroid injection and a relatively long hospitalization period produced the most favorable result.
RESUMO
BACKGROUND@#Three-dimensional (3D) cell cultures with architectural and biomechanical properties similar to those of natural tissue have been the focus for generating liver tissue. Microarchitectural organization is believed to be crucial to hepatic function, and 3D cell culture technologies have enabled the construction of tissue-like microenvironments, thereby leading to remarkable progress in Vitro models of human tissue and organs. Recently, to recapitulate the 3D architecture of tissues, spheroids and organoids have become widely accepted as new practical tools for 3D organ modeling. Moreover, the combination of bioengineering approach offers the promise to more accurately model the tissue microenvironment of human organs. Indeed, the employment of sophisticated bioengineered liver models show long-term viability and functional enhancements in biochemical parameters and disease-orient outcome. @*RESULTS@#Various 3D in Vitro liver models have been proposed as a new generation of liver medicine. Likewise, new biomedical engineering approaches and platforms are available to more accurately replicate the in vivo 3D microarchitectures and functions of living organs. This review aims to highlight the recent 3D in Vitro liver model systems, including micropatterning, spheroids, and organoids that are either scaffold-based or scaffold-free systems. Finally, we discuss a number of challenges that will need to be addressed moving forward in the field of liver tissue engineering for biomedical applications. @*CONCLUSION@#The ongoing development of biomedical engineering holds great promise for generating a 3D biomimetic liver model that recapitulates the physiological and pathological properties of the liver and has biomedical applications.

BACKGROUND AND OBJECTIVES@#We aimed to evaluate the effect of the level of education on the prevalence of tinnitus and quality of life (QoL) in the Korean population. SUBJECTS AND METHOD: Our study included 3155 participants from a representative sample. Tinnitus was measured using questionnaires that evaluated perception of ringing, buzzing, roaring, or hissing sounds. Participants were asked to indicate ââ¬ÅYesââ¬Â or ââ¬ÅNoââ¬Â to these questions. Participants who felt that the sensation was ââ¬ÅA little annoyingââ¬Â or ââ¬ÅVery annoyingââ¬Â were considered to have moderate or severe tinnitus, respectively. Hearing thresholds were measured using an automatic audiometer. QoL was evaluated using the EuroQoL (EQ) scale. @*RESULTS@#The number of participants in the low, middle, and high education groups were 1521, 967, and 667, respectively. Participants with any degree of tinnitus or moderate to severe tinnitus increased as the level of education decreased. Multivariate logistic regression analysis showed that the low education group had significantly higher odds ratios compared to the middle or high education groups for moderate to severe tinnitus. Abnormal EQ 5-dimensions (EQ-5D) were higher in participants with tinnitus and a low level of education. For participants, univariate and multivariate analyses showed EQ-5D index and EQ-visual analog scale in the low education group were lower than that in the other groups. @*CONCLUSION@#Our study showed that low education level was associated with moderate to severe tinnitus in the Korean adult population. Participants with tinnitus and a low level of education had poorer QoL than those with tinnitus and a high level of education.
RESUMO
BACKGROUND: The present study aimed to evaluate the clinical association between cadmium exposure and hearing impairment among the Korean population.METHODS: This retrospective cross-sectional study used the data obtained from the Korean National Health and Nutrition Examination Survey were used for our study. Finally, 3,228 participants were included in our study, which were then divided into quartiles based on their blood cadmium levels: first quartile (1Q), second quartile (2Q), third quartile (3Q), and fourth quartile (4Q) groups. The hearing thresholds were measured using an automatic audiometer at 0.5, 1, 2, 3, 4, and 6 kHz. Hearing loss (HL) was defined as >25 dB average hearing threshold (AHT).RESULTS: All the groups had 807 participants each. The area under the receiver operating characteristic curves of cadmium level for HL were 0.634 (95% confidence interval [CI], 0.621–0.646). The participants in the 4Q group had higher Low/Mid-Freq, High-Freq, and AHT values than those in the other groups in the multivariate analysis after adjusting for confounding factors. The logistic regression showed that the OR for HL per 1 µg/L increase in cadmium was 1.25 (95% CI, 1.09–1.44; p=0.002) on the multivariate analysis. Moreover, the multivariate logistic regression analyses revealed that the participants in the 4Q group exhibited a 1.59-, 1.38-, and 1.41-fold higher odds for HL than those in the 1Q, 2Q, and 3Q groups, respectively.CONCLUSION: High cadmium level quartile was associated with increased hearing thresholds and HL among the Korean adult population.

Congenital intratympanic membrane cholesteatoma (ITMC) is a rare type of congenital cholesteatoma located within the tympanic membrane. This lesion tends to increase in size over time. The development of ITMC can cause several complications such as hearing impairment, dizziness, facial palsy, and intracranial complications, similar to any other cholesteatoma. The treatment of congenital cholesteatoma requires the removal of the lesion through surgery, because disease progression induces bony destruction of the nearby tissue. Most patients presenting with this cholesteatoma type are also treated with primary surgical removal. However, we recently experienced a case of an ITMC that showed a natural transition to an external auditory canal cholesteatoma.
