Results of a New Treatment Protocol for Sudden Sensorineural Hearing Loss Using Betamethasone for Intratympanic Therapy.

Introduction Sudden sensorineural hearing loss (SSNHL) is defined as a rapid sensation of hearing impairment in one or both ears. Based on its personal impact on patients, the present study advances the analysis of new treatments for the prompt recognition and management of SSNHL, with higher chances of improvements in terms of hearing recovery and quality of life of the patients. Objective To describe the intratympanic (IT) corticoid infiltration technique, to demonstrate the efficacy of betamethasone injection as a sequential treatment in patients whose initial systemic steroid treatment failed, as well as to compare its use in different treatment periods. Methods The present clinical trial was conducted with 37 patients referred to our office with the diagnosis of SSNHL, from September 2019 to May 2022, who provided informed consent to participate. Results Even dividing the analysis of increasing the pure tone average (PTA) or speech recognition threshold (SRT) between the difference into initiation of the salvage therapy in up to 15 days of the sudden deafness event, and between 15 days and 3 months of the event, we did not find any difference in hearing improvement. Conclusion Intratympanic corticosteroid therapy is prescribed when conventional therapy fails or when there is a limitation to the use of corticosteroids due to the presence of systemic disorders. As such, new drugs, such as bethametasone, are studied and show promising results.

The therapeutic potential of natural medicine puerarin for depression

The incidence of depression has steadily increased in recent years, making it one of the most prevalent mental disorders. As the pursuit of new antidepressant drugs has attracted wide attention in the pharmaceutical community, the therapeutic effects of traditional Chinese medicine have also been extensively explored. Puerarin is commonly used as a vasodilator in the treatment of coronary heart disease including angina and myocardial ischemia, cerebral infarction, retinal vein occlusion, and sudden deafness. However, the potential of puerarin in the treatment of depression is very great, so this article reviews the latest research progress of puerarin in the mechanism of depression in recent years, and discusses its application prospect in depression. In addition, we also discuss the related pathological mechanism of depression, which provides new insights for further understanding of depression. However, despite the great potential of puerarin, further studies are needed to elucidate its specific mechanism of action and evaluate its effectiveness in human subjects.

Case Report: - Sudden sensorineural hearing loss and vertigo due to inner ear hemorrhage

Sudden deafness is a common cause of emergency consultation in otology. Usually, despite investigations, no etiology is known. Intracochlear hemorrhage is a rare cause of sudden sensorineural hearing loss (SSNHL) and may be associated with various labyrinthine disorders. In such cases, magnetic resonance imaging (MRI) is the clef of the diagnosis. We report the case of a 70-year-old patient who was referred to our department for sudden hearing loss, tinnitus, and vertigo. Otoscopic and neurological examinations were normal, and pure-tone audiometry revealed left profound sensorineural hearing loss. Videonystagmography (VNG) revealed left vestibular deficit. MRI demonstrated a high signal intensity inside the cochlea on unenhanced T1-weighted images, and no other abnormalities were found; in particular, no enhancement after intravenous administration of gadolinium. No etiology was identified. Vertigo disappeared rapidly with corticosteroid treatment and hyperbaric oxygen therapy, but hearing did not improve. Intra-labyrinthine hemorrhage causing SSNHL is rare, and the hearing prognosis is poor.

Characterization of the components in plasma EVs unveiling the link between EVs-derived complement C3 with the severity and initial treatment response of profound sudden sensorineural hearing loss

BackgroundSudden sensorineural hearing loss (SSNHL) is characterized by rapid, unexplained loss of hearing within a 72-hour period and exhibits a high incidence globally. Despite this, the outcomes of therapeutic interventions remain largely unpredictable, especially for those with profound hearing loss. Extracellular vesicles (EVs), nano-sized entities containing biological materials, are implicated in the development of numerous diseases. The specific relationship between EVs and both the severity and treatment effectiveness of SSNHL, however, is not well understood. MethodsThis study involved the analysis of medical records from the Department of Otolaryngology (September 1, 2020 − December 31, 2022) of patients diagnosed with SSNHL according to the 2015 Guidelines for Diagnosis and Treatment of Sudden Deafness in China. Peripheral blood samples from patients with various types of SSNHL before and after treatment were collected, alongside samples from healthy volunteers serving as controls. Plasma EVs were isolated using gel rejection chromatography and analyzed for concentration, marker presence, and morphology using Nanosight, Western blot, and transmission electron microscopy (TEM), respectively. Proteomics and miRNA assessments were conducted to identify differentially expressed proteins and miRNAs in the plasma EVs of SSNHL patients and healthy volunteers. Key proteins were further validated through Western blot analysis. Enzyme-linked immunosorbent assay (ELISA) was utilized to determine the levels of complement C3 in plasma EVs, and correlation analyses were performed with audiological data pre- and post-treatment. ResultsPlasma from SSNHL patients of varying types was collected and their EVs were successfully isolated and characterized. Proteomic analysis revealed that complement C3 levels in the plasma EVs of patients with profound SSNHL were significantly higher compared to healthy controls. Differential expression of miRNAs in plasma EVs and their related functions were also identified. The study found that the level of complement C3 in plasma EVs, but not the total plasma complement C3, positively correlated with the severity of SSNHL in patients exhibiting positive therapeutic responses, particularly in those with initially lower levels of EV-associated complement C3. After treatment, complement C3 level was decreased in patients with initially higher levels of EV-associated complement C3. No significant correlation was observed between changes in plasma EV-derived complement C3 levels and the degree of hearing loss in either responders or non-responders among patients with profound SSNHL. ConclusionDifferential profiles of proteins and miRNAs were identified in patients with profound SSNHL. Notably, plasma EV-derived complement C3 was linked to both the severity and early treatment effectiveness of patients with profound SSNHL.

Ten years of detecting Neoehrlichia mikurensis infections in Sweden: demographic, clinical and inflammatory parameters.

To increase knowledge about the varied clinical manifestations of human infection with the emerging tick-borne pathogen Neoehrlichia mikurensis. All patients diagnosed in Sweden with N. mikurensis infection during a 10-year period (2013-2023) were investigated regarding their demographic factors, risk factors, comorbidities, clinical signs and symptoms, and laboratory results. Multivariate models were generated using "Orthogonal Projections to Latent Structures-Discriminant Analysis" to identify clinical and immune parameters associated with N. mikurensis infection. During the 10-year period, 134 patients were diagnosed with N. mikurensis infection, 102 of whom were included in this study. Most of the patients (79%) were immunosuppressed. The main comorbidities were malignant B-cell lymphomas, multiple sclerosis, and rheumatoid arthritis. Rituximab therapy (59%) and splenectomy (14%) featured prominently. All patients resided in the southern tick-endemic part of Sweden, yet one-third of them were diagnosed in wintertime when ticks are inactive. Two asymptomatically infected blood donors were identified but transfusion-transmitted infection was not confirmed. Increased levels of C-reactive protein, orosomucoid, and total IgM in serum were associated with neoehrlichiosis. Previously unreported symptoms such as ankle edema, neck pain, numbness, and sudden deafness were detected in some patients. One case of aplastic anemia partially improved after eradication of the infection. Neoehrlichiosis is a multi-faceted emerging infectious disease.

Residual Dizziness Characteristics of Idiopathic Sudden Sensorineural Hearing Loss Patients with Benign Paroxysmal Positional Vertigo.

ISSNHL, a common clinical condition, can be accompanied by vertigo. Initially, research on sudden deafness primarily focused on the hearing loss itself, with less emphasis on episodic vertigo. However, as vertigo research has advanced, it has been recognized that BPPV is a frequent accompaniment to ISSNHL-associated vertigo. Even after treatment, some patients may experience residual dizziness. This study investigates the characteristics of patients with ISSNHL accompanied by BPPV and the impact of residual dizziness on their lives. This study is being conducted on patients with ISSNHL accompanied by BPPV, analyzing the characteristics of such patients and the impact of residual dizziness on their lives. Overall, 54 adult inpatients with ISSNHL and BPPV were included in this study. All patients received 50 mg of intravenous prednisolone for 5 consecutive days and hemodilution agents for 10 days. At the same time, BPPV was treated with repositioning by the same therapist using the SRM-IV vertigo diagnostic and treatment system, and different repositioning methods were used for different types of otolithiasis. Patients were grouped according to the absence of residual dizziness when the nystagmus disappeared at the time of discharge. There were 24 cases in the group with residual symptoms, including 10 males and 14 females. The proportion of females was 58.33%, with an average age of 46.75 ± 13.80. The group without residual symptoms consisted of 30 cases, including 13 males and 17 females. The female proportion was 56.67%, with an average age of 45.77 ± 11.86. There is no statistical significance between the two groups in the pre-treatment hearing status and DHI scores. The HAMA (Hamilton Anxiety Rating Scale) scores before treatment were compared, revealing a significant statistical difference. ISSNHL-associated BPPV may be caused by vascular embolism or thrombosis in the cochlear or spiral modiolar artery. This disrupts blood flow, leading to ischemia in the otolithic membrane and subsequent detachment of otoconia. Because this detachment often occurs within 24 h of the initial event, patients experience positional vertigo early in the course of the disease.

Metrology analysis and thoughts of literatures on tinnitus associated with sudden deafness based on CiteSpace

Objective: To explore the incidence of sudden deafness accompanied with tinnitus, the selection of examination protocols and treatment, and to provide reference for the establishment of new guidelines for sudden deafness. Methods: CiteSpace software was used for analysis and data mining to analyze and summarize the computer-retrieved articles on diagnostic examination and treatment of sudden deafness accompanied with tinnitus collected from CNIC, Wanfang and Web of Science databases from 2011 to 2021. Results: A total of 207 randomized controlled studies were retrieved in this study, including 121 in Chinese and 86 in English. Finally, 74 Chinese literatures and 16 English literatures were included. Among the 74 valid Chinese literatures, 64 (86.5%) were accompanied with tinnitus, 58 (78.4%) with dizziness/vertigo, 25 (33.8%) with aural fullness, 10 (13.5%) with headache, 4 (5.4%) with insomnia, 4 (5.4%) with a mixture of dizziness and tinnitus, and 2 (2.7%) with vomiting. Among the 16 English literatures, 15 (93.8%) were accompanied with tinnitus, 12 (75.0%) with vertigo, 1 (6.3%) with aural fullness, and 1 (6.3%) with a mixture of various symptoms. Among the 64 Chinese articles mentioning tinnitus, only 9 mentioned tinnitus matching tests, and 1 mentioned that the treatment for tinnitus accompanying symptoms was sound therapy and psychological counseling. The incidence rates of tinnitus accompanying four different types of sudden deafness, from low to high, are as follows: low-to-mid frequency, 82.4%; mid-to-high frequency, 90.7%; complete deafness, 92.4%; and flat type, 92.8%. Conclusion: Tinnitus is the most common accompanying symptom of sudden deafness, and tinnitus matching test is an effective evaluation method. When establishing a scientific, comprehensive, and systematic diagnosis and treatment system or guidelines for sudden deafness, attention should be paid to the diagnosis and treatment of tinnitus symptoms and their adverse psychological reactions, in order to reduce the incidence of tinnitus patients in the later stage of recovery from sudden deafness.

Prognosis of 109 cases of sudden sensorineural hearing loss in children

Objective:To analyze the factors influencing the prognosis of sudden sensorineural deafness in children, and to provide theoretical basis for clinical prevention and treatment. Methods:The clinical data of 109 children with sudden deafness admitted to our hospital from 2016 to 2023 were retrospectively analyzed. The children were grouped according to eight related factors, including gender, age, climate, duration of hearing loss, concomitant symptoms, degree of hearing loss, sicken ear, and auditory curve. The chi-square test was used for univariate analysis, and logistic regression was employed to identify factors influencing prognosis. Results:After conventional treatment, 56 cases were ineffective（51.40%）, 30 cases were effective（27.5%）, 13 cases were effective（11.9%）, 10 cases were cured（9.2%）, and the total effective rate was 48.6%. Among concomitant symptoms, children with tinnitus had better treatment results（P<0.05）; In the degree of hearing loss, the effective rate of mild hearing loss was the highest（83.3%）, and the effective rate of very severe hearing loss was the lowest（40.0%）. The prognosis of low frequency decline and high frequency decline were better（P<0.05）; There was no significant correlation between gender, age, climate, duration of hearing loss, sicken ear and prognosis（P>0.05）. Conclusion:The auditory curve and the degree of hearing loss are the factors affecting the prognosis of children with sudden deafness. Additionally, children with tinnitus tend to have a better prognosis.

Effect of acupuncture intervention time on the therapeutic effect in patients with sudden hearing loss.

To observe the clinical efficacy of acupuncture intervention at different time for patients with sudden hearing loss. According to the timing of acupuncture intervention, 86 patients were divided into early exposure group (n=43) and late exposure group (n=43) . The early exposure group was given acupuncture treatment within 14 days of onset, and the late exposure group was given acupuncture treatment after 14 days of onset. After propensity score matching (PSM, a statistical matching technique for observational data) processing by using SPSS26.0 software, outcomes of 30 cases in the early exposure group and 30 cases in the late exposure group were analyzed. In addition to receiving basic treatment with drugs for vascular dilatation, thrombolysis, nourishing nerve, etc., all patients of the two groups were treated with neck acupuncture ("Neck Seven Meridian Lines" acupuncture), once every other day except Sundays, for a total of 12 time. Before, after the treatment and 3 months after the treatment, the total score of the Tinnitus Handicap Inventory (THI, 0, 2 and 4 points for each of the 25 items, total scores = 100 points) scale was used to evaluate the improvement of tinnitus symptoms caused by hearing loss. The clinical therapeutic effect was evaluated according to the efficacy grading criteria in the Guidelines for Diagnosis and Treatment of Sudden Deafness (2015) and the changes of pure tone audiometry curve. Multivariate Logistic regression was used to analyze the effect of factors that might influence efficacy before propensity score matching. The THI scores of patients in both groups decreased strikingly after the treatment and 3 months' follow-up (P<0.05). Compared with the same time-points of the late exposure group, the total THI scores of post-treatment and 3 months' follow-up were evidently lower in the early exposure group (P<0.05). The effective rate of the early exposure group (22/30, 80.00%) was significantly higher (P<0.05) than that of the late exposure group (16/30, 53.33%). The classification of sudden deafness and the application of traditional Chinese medicine in this study were not independent factors affecting the total effective rate. The time point of acupuncture intervention is an important factor affecting the effect on hearing and tinnitus disability of patients with sudden deafness. The earlier acupuncture treatment is accepted, the better the therapeutic effect is.

Case Report - Sudden sensorineural hearing loss and vertigo due to inner ear hemorrhage

Sudden deafness is a common cause of emergency consultation in otology. Usually, despite investigations, no etiology is known. Intracochlear hemorrhage is a rare cause of sudden sensorineural hearing loss (SSNHL) and may be associated with various labyrinthine disorders. In such cases, magnetic resonance imaging (MRI) is the clef of the diagnosis. We report the case of a 70-year-old patient who was referred to our department for sudden hearing loss, tinnitus, and vertigo. Otoscopic and neurological examinations were normal, and pure-tone audiometry revealed left profound sensorineural hearing loss. Videonystagmography (VNG) revealed left vestibular deficit. MRI demonstrated a high signal intensity inside the cochlea on unenhanced T1-weighted images, and no other abnormalities were found; in particular, no enhancement after intravenous administration of gadolinium. No etiology was identified. Vertigo disappeared rapidly with corticosteroid treatment and hyperbaric oxygen therapy, but hearing did not improve. Intra-labyrinthine hemorrhage causing SSNHL is rare, and the hearing prognosis is poor.

Focus on the effect of nursing care combined with cognitive intervention and functional training on negative emotion, compliance and quality of life in elderly patients with sudden deafness: A retrospective study.

To explore the effects of focused solution nursing combined with cognitive intervention combined with functional training on negative emotions, compliance and quality of life in elderly patients with sudden deafness. A total of 160 patients with sudden deafness in the elderly who were treated in our hospital from January 2019 to May 2021 were selected as the objects of this retrospective study. Based on different treatment approaches, subjects were divided into a control group and an observation group. Due to reasons such as the COVID-19 pandemic and transfers, 10 cases were lost to follow-up. In total, 75 cases were ultimately lost from both the control and observation groups. The control group implements cognitive intervention and functional training, and the observation group adopts focused solution nursing care on the basis of the control group. Observe and compare the effects of negative emotions, psychological distress, air conduction threshold level, compliance and quality of life of the 2 groups of patients. The air conduction hearing threshold level of the 2 groups of patients after nursing was lower than that before nursing and the observation group was lower than the control group. The positive coping scores of the 2 groups were significantly increased, and the negative coping scores were both significantly reduced and the observation group was in the 2 indicators. The degree of change was greater than that of the control group (P < .05). After nursing, the self-rating anxiety scale (SAS) and self-rating depression scale (SDS) of the observation group were lower than those of the control group (P < .05). The mental vitality score, social interaction score, emotional restriction score, and mental status of the observation group were significantly higher than those of the control group. The observation group's psychological compliance, activity compliance, dietary compliance, and treatment protocol compliance were significantly higher than those of the control group (P < .05). Adopting the focused solution model of nursing care can provide a better nursing recovery for elderly patients with sudden deafness, significantly improve the patient quality of life and anxiety and depression, improve patient compliance with treatment, and provide a certain reference for the nursing of elderly patients with sudden deafness.

Management of Traumatic Perforation of Tympanic Membrane Through Ayurveda

Traumatic tympanic perforations can occur due to various reasons, such as concussion, insertion of objects, temporal bone fractures, barotrauma, etc. Slap injuries are a common cause. Symptoms include sudden conductive deafness, pain and/or blood-stained discharge. Tinnitus and vertigo may complicate the condition. Appropriate and timely management is crucial to reduce the risk of permanent impairment, as studies indicate that spontaneous healing occurs within 1.5 to 3 months. While Ayurvedic texts don’t directly mention traumatic tympanic perforations, they can be categorized as ‘Agantuja Vrana’ (wounds caused by external factors). Ayurvedic treatment includes both local and systemic approaches. In this case study, medicines were used internally for 2 months: Sarivadi Vati, Lakshadi Guggul, Mahayograj Guggul, Gandha Taila capsules and a combination of Vatashamaka Churnas. This combination led to significant improvement; the perforation completely healed in 2 months. Thus, internal use of these drugs helped in the healing of traumatic perforations.

Clinical Observations on the Combined Use of Hyperbaric Oxygenation and Conventional Medications in the Management of Type 2 Diabetes Mellitus Concurrent With Sudden Deafness.

Objective: The aim of this study is to investigate the effectiveness of combining hyperbaric oxygen therapy (HBOT) with conventional pharmacological interventions in the management of type 2 diabetes mellitus concurrent with sudden deafness. Methods: A cohort of 96 patients diagnosed with sudden deafness was enrolled and subsequently randomized into 2 groups: a treatment group (n = 50) and a control group (n = 46). The control group received standard conventional treatment aimed at enhancing microcirculation and nutritional support for nerves, while the treatment group underwent conventional symptomatic treatment coupled with HBOT. The evaluation encompassed the monitoring of blood glucose and blood lipid levels, clinical efficacy, and absolute hearing threshold improvement in both groups. Results: Following the intervention, noteworthy reductions in blood glucose and blood lipid levels were observed in both groups compared to their respective pretreatment values. Furthermore, posttreatment values in the treatment group exhibited a statistically significant decrease in comparison to those in the control group (P < .05). On assessing clinical efficacy posttreatment, the treatment group demonstrated a significantly higher efficacy than the control group (P < .05). In addition, the absolute hearing thresholds in both groups exhibited a significant decrease posttreatment compared to baseline values. Notably, the treatment group displayed a statistically significant reduction in absolute hearing thresholds compared to the control group posttreatment (P < .05). Conclusion: The combined therapeutic approach utilizing hyperbaric oxygen exhibits effectiveness in mitigating auditory impairment among individuals manifesting sudden deafness concomitant with type 2 diabetes mellitus. Furthermore, this treatment approach is associated with a concurrent reduction in blood glucose and blood lipid levels.

Could Sudden Unilateral Sensorineural Hearing Loss be the Only Manifestation of COVID-19: Case Report

Auditory neuritis associated with cochleitis has already been described in viral damage; Several mechanisms are mentioned; either indirectly by an antibody response that cross-reacts with an inner ear antigen, or directly by an invasion of the cochlear nerve or anterior labyrinth. Non-specific symptoms such as SSNHL might be the only sign to recognize COVID-19 cases. The aim of this article is to report case of 35 year old man; who presented sudden unilateral deafness as the only symptom of SARS covid 19.

Clinical Relevance of Plasma Lactic Acid in the Onset and Prognosis of Sudden Deafness.

Sudden deafness poses a significant threat to patients' quality of life, yet effective indicators for evaluating its onset and prognosis remain elusive. The inner ear is primarily supplied by the labyrinthine artery, which lacks collateral circulation. Changes in coagulation function and hemorheology can cause spasm or thrombosis of the labyrinthine artery, leading to ischemia, hypoxia, and microcirculation disorders in the inner ear, ultimately resulting in sudden deafness. This retrospective study examined 196 patients with sudden deafness, utilizing the 2015 Chinese guideline for diagnosis and treatment classification. Coagulation system analysis used the STA-R Evolution automatic coagulation analyzer, measuring activated partial thromboplastin time (APTT), prothrombin time (PT), and fibrinogen (FIB). Plasma lactate concentration was determined using a Johnson and Johnson Fusion 5.1 model plasma lactate detector. Results of the study revealed a correlation between the degree of hearing loss and disease prognosis. Patients with higher grade hearing loss exhibited elevated plasma lactate levels upon admission compared with those with lower grade hearing loss. Importantly, elevated plasma lactate levels at admission served as predictive indicators for treatment outcomes. In addition, patients with ineffective treatment demonstrated a more coagulable blood state, as evidenced by the lower APTT (ineffective treatment: 31.47 ± 4.55 seconds, effective treatment: 35.17 ± 5.38 seconds) and PT on admission, but higher plasma FIB. In conclusion, plasma lactate levels upon admission hold promise as prognostic markers for sudden deafness treatment outcomes, providing valuable insights for clinical management.

Reactivation of hepatitis C virus caused by steroid monotherapy for sudden deafness

Hepatitis C virus (HCV) reactivation has been reported to be caused due to several anticancer drugs and immunosuppressive agents; however, HCV reactivation after steroid monotherapy has rarely been reported. Here, we report the case of a 65-year-old Japanese man with HCV infection who developed HCV reactivation after the administration of prednisolone (PSL) for 6 days for sudden deafness. In the patient history, the positivity for anti-HCV antibody was observed, but serum level of HCV RNA was not measured. Two months after PSL administration, the patient experienced an alanine aminotransferase (ALT) flare and the serum level of HCV RNA was observed to be 6.2 log IU/mL; then, the patient was admitted to our hospital for hepatitis treatment. Based on the clinical course and laboratory findings, the patient was diagnosed with HCV reactivation. Although the ALT levels decreased spontaneously during follow-up, they did not drop to normal range; subsequently, sofosbuvir and ledipasvir treatments were started. A sustained virological response 24 weeks after the end of treatment was achieved. This case study suggests that HCV reactivation with hepatitis flare can occur even after a steroid monotherapy, and doctors should pay attention to HCV reactivation when administering PSL for patients with HCV infection.

A Comprehensive Study on Sudden Deafness for Analyzing Their Clinical Characteristics and Prognostic Factors.

Background: To study the factors associated with the prognosis of patients with sudden deafness to facilitate clinical treatment and improve efficacy. Methods: A total of 414 patients with sudden deafness treated in Zhenjiang First People's Hospital from January 2020 to December 2022 were chosen. Relevant data were gathered and the effectiveness of treatment was assessed by comparing hearing test results before and after hospital admission and divided into effective and ineffective groups, and the effectiveness of each factor was analyzed using univariate analysis, Spearman's correlation analysis, and multifactor logistic regression. Results: The 2 groups had significant differences in age, presence of tinnitus, degree of hearing loss, and triglyceride levels. Spearman's rank correlation analysis showed a negative correlation between hearing threshold of at least 81 dB at 250 to 8000 Hz, the low-density lipoprotein (LDL), triglyceride levels, and the prognosis (r < 0, P < .001). A positive correlation exists between high-density lipoprotein levels and prognosis (r > 0, P < .001). Receiver operating characteristic curve showed LDL level, age, and time since disease onset appears to be highly predictive. Multivariable logistic regression analysis showed that age >47 years, LDL >2.93 mmol/L, and time to presentation >10 days after disease onset are at higher risk for poor prognosis. Conclusion: Factors that influence the prognosis of patients with sudden deafness include age, tinnitus symptoms, high LDL levels, and the type of hearing curve. Early intervention and targeted treatment should be given to high-risk patients to improve the outcome of sudden deafness in clinical practice.

Prevalence of hearing loss, tinnitus, vertigo and sudden deafness among patients with polymyositis and dermatomyositis

Little is known about a possible association of autoimmune inner ear disease among patients diagnosed with polymyositis (PM)/dermatomyositis (DM). This study aimed to explore differences in the prevalence of inner ear symptoms among patients with and without PM/DM using a nationwide population-based dataset. Data for this study were retrieved from the Taiwan National Health Insurance Research Database. The study sample included 1622 patients diagnosed with PM/DM and 8109 propensity-score matched comparison patients without PM/DM. We performed multivariate logistic regressions to calculate odds ratios (ORs) and 95% confidence interval (CI) for tinnitus, hearing loss, sudden deafness, and vertigo among patients with PM/DM versus comparison patients. Chi-square tests showed statistically significant differences between patients with PM/DM and comparison patients in the prevalence of tinnitus (16.1% vs. 12.7%, p < 0.001), non-conductive hearing loss (9.2% vs. 6.8%, p < 0.001), and vertigo (14.4% vs. 11.1%, p < 0.001). The adjusted ORs for tinnitus, non-conductive hearing loss, and vertigo, respectively, were 1.332 (95% CI = 1.147–1.547), 1.399 (95% CI = 1.154–1.696), and 1.374 (95% CI = 1.173–1.611) for patients with PM/DM when compared to comparison patients. Our study finds that patients with PM/DM have higher prevalence rates of tinnitus, non-conductive hearing loss, and vertigo than comparison patients.

The psychological intervention and clinical efficacy of Rosenthal effect and acupuncture bleeding on middle-aged and young patients with sudden hearing loss.

Combining traditional Chinese medicine theory and modern medical knowledge, this study explores the pathogenesis of sudden hearing loss in middle-aged and young people. Sixty-four young and middle-aged patients with sudden hearing loss who visited a public tertiary hospital in China are chosen as experimental objects. All experimental patients are broken into an experimental group (n = 32) and a control group (n = 32). The control group receive conventional Western medicine treatment regimen. The experimental group receive select acupoint acupuncture and bloodletting combined with Rosenthal effect for psychological intervention, and both groups have a treatment course of 14 days. The changes in the patient's condition before and after treatment are observed, and the differences in hearing threshold values, tinnitus, and dizziness clinical efficacy before and after treatment are observed and recorded. It evaluates the efficacy using the Anxiety, Depression Scale, and Hope Scale and statistically analyzes the data. The dizziness score of the experimental group decreased rapidly, the treatment onset time was shorter, and the improvement effect on dizziness symptoms was better (P < .05). After 1 month of intervention treatment, the intervention of the experimental group was better (P < .05). The hope level and self-efficacy of both groups of patients were raised in contrast with before treatment (P < .05). After 1 month, the intervention effect of the experimental group was more significant (P < .01). Both groups could improve patient ear blood circulation, but the experimental group had lower plasma viscosity, hematocrit, and red blood cell aggregation index, higher red blood cell deformation index, and more significant improvement effect (P < .05). The effective rates of improving hearing and tinnitus in the experimental group reached 87.5% and 81.5%, and the clinical treatment efficacy was better than that in the control group (P < .05). The level of depression and anxiety in the experimental group remained relatively stable, while that in the control group showed a significant rebound (P < .05). In conclusion, both groups had a certain effect in treating sudden deafness, both of which could effectively improve the patient's hearing. But in contrast with the control group, the experimental group had better clinical efficacy, higher safety, and better psychological intervention results, which is worthy of clinical promotion.
