Patients with vertigo often experience cognitive symptoms such as attention deficits, memory problems, and spatial perception difficulties. This study aimed to explore the cognitive impairments associated with Benign paroxysmal positional vertigo(BPPV) and Meniere's Disease(MD). A non-experimental group comparison design was used with 107 participants divided into three groups: Group I(clinically normal), Group II(BPPV), and Group III(MD). Participants completed a questionnaire with 10 cognition-related questions, and their responses were scored. The data were found to be non-normally distributed. The analysis revealed a significant difference in scores between Group I and both Group II and Group III. Chi-square tests showed that the responses to cognition-related questions varied among the groups, with Group II exhibiting more cognitive problems. Associated conditions like hypertension, diabetes, and hearing loss did not significantly influence the responses within each group. This study suggests a significant relationship between cognitive problems and patients with BPPV and MD. However, there was no association found between the cognitive problems experienced in BPPV and MD patients. These findings align with previous research indicating that vestibular disorders can lead to deficits in spatial memory, attention, and other cognitive functions. By understanding the link between cognition and vestibular disorders, we can improve diagnosis and rehabilitation services to enhance the quality of life for these patients.展开更多

Surgery is performed based on limbic system circuit theory correspondence to above-mentioned hypothesis. Stereotactic surgery for the treatment of mental disorders is related to stereotactic surgery that influences the Papez circuit. OBJECTIVE: To observe the effects of stereotactic multi-target limbic leucotomy on the improvements in memory, intelligence and psychiatric symptoms in the treatment of intractable psychiatric disease. DESIGN: Self-control case analysis and follow-up of therapeutic effects. SETTING: Department of Neurosurgery, First Hospital, Hebei Medical University. PARTICIPANTS: Thirty patients with intractable psychiatric disease, who received stereotactic surgery in the Department of Neurosurgery, First Hospital, Hebei Medical University between July 2002 and August 2005, were included in this study. The patients, 21 males and 9 females, all met the diagnostic criteria of intractable psychiatric disease, determined by the national psychosurgery cooperation team in 1998. Informed consents for surgery and clinical follow-up exams were obtained from patients and/or patients' relatives (guardians). METHODS: In 30 patients with intractable psychiatric disease, limbic leucotomy was performed by stereotactic technique. Multi-target radiofrequency hyperthermia was performed in the intracranial amygdaloid nucleus, anterior limb of internal capsule, callosal gyrus, among other regions. The therapeutic effects of patients were evaluated by Brief Psychiatric Rating Scale (BPRS) before surgery, and 6 months, 1, and 3 years after surgery. The Wechsler Adult Intelligence Scale (WAIS) and Clinical Memory Scale (CMS) were used to assess memory and intelligence before and after surgery. MAIN OUTCOME MEASURES: Memory, intelligence, and psychiatric symptoms of patients before and after operation. RESULTS: Thirty patients were included in the final analysis. (1) Memory and intelligence changes of patients: CMS and WAIS showed there were no significant differences in the changes of brain functions before and after operation (P 〉 0.05). (2) Improved degree of symptoms: 5 patients were cured, 8 patients significantly improved, 8 patients improved, 3 patients had no changes, and 6 patients had recurrent symptoms. CONCLUSION: Stereotactic multi-target limbic leucotomy can improve the symptoms of patients with intractable psychiatric disease. Follow-up results showed that memory and intelligence were not noticeably improved after surgery.展开更多

Modified titration protocol of ITG at a low dose(20 mg/m L) was administered to 10 patients with definite unilateral intractable MD. After initial first two fixed ITGs on weekly basis,the patients might or might not be given any more injections,depending on the appearance of unilateral vestibular loss(UVL). ITG was terminated if the patients satisfied the criteria of UVL. All patients were followed-up for at least two years. The effects of ITG on the vertigo attack,functional level scores and postural balance were evaluated. Of the 10 cases,8 showed the sign of UVL after receiving initial two ITGs and were not given any more intratympanic injections,and the other 2 patients were administered three ITGs. A two-year follow-up revealed that complete and substantial vertigo control was achieved in 9 cases,and limited vertigo control in 1 patient. Hearing level was lowered in 2 patients. The posture stability and functional level scores were improved. Our study showed that the modified titration protocol of ITG at a low dose could effectively control vertigo in patients with unilateral intractable MD.展开更多

文摘The vestibular system connects the inner ear to the midbrain and subcortical structures and can affect cognition. Patients with vertigo often experience cognitive symptoms such as attention deficits, memory problems, and spatial perception difficulties. This study aimed to explore the cognitive impairments associated with Benign paroxysmal positional vertigo(BPPV) and Meniere's Disease(MD). A non-experimental group comparison design was used with 107 participants divided into three groups: Group I(clinically normal), Group II(BPPV), and Group III(MD). Participants completed a questionnaire with 10 cognition-related questions, and their responses were scored. The data were found to be non-normally distributed. The analysis revealed a significant difference in scores between Group I and both Group II and Group III. Chi-square tests showed that the responses to cognition-related questions varied among the groups, with Group II exhibiting more cognitive problems. Associated conditions like hypertension, diabetes, and hearing loss did not significantly influence the responses within each group. This study suggests a significant relationship between cognitive problems and patients with BPPV and MD. However, there was no association found between the cognitive problems experienced in BPPV and MD patients. These findings align with previous research indicating that vestibular disorders can lead to deficits in spatial memory, attention, and other cognitive functions. By understanding the link between cognition and vestibular disorders, we can improve diagnosis and rehabilitation services to enhance the quality of life for these patients.

MAIN OUTCOME MEASURES: Memory, intelligence, and psychiatric symptoms of patients before and after operation. RESULTS: Thirty patients were included in the final analysis. (1) Memory and intelligence changes of patients: CMS and WAIS showed there were no significant differences in the changes of brain functions before and after operation (P 〉 0.05). (2) Improved degree of symptoms: 5 patients were cured, 8 patients significantly improved, 8 patients improved, 3 patients had no changes, and 6 patients had recurrent symptoms. CONCLUSION: Stereotactic multi-target limbic leucotomy can improve the symptoms of patients with intractable psychiatric disease. Follow-up results showed that memory and intelligence were not noticeably improved after surgery.

文摘This study looked into the efficacy of a modified titration protocol of intratympanic gentamicin injection(ITG) in the patients with unilateral intractable Ménière's disease(MD). Modified titration protocol of ITG at a low dose(20 mg/m L) was administered to 10 patients with definite unilateral intractable MD. After initial first two fixed ITGs on weekly basis,the patients might or might not be given any more injections,depending on the appearance of unilateral vestibular loss(UVL). ITG was terminated if the patients satisfied the criteria of UVL. All patients were followed-up for at least two years. The effects of ITG on the vertigo attack,functional level scores and postural balance were evaluated. Of the 10 cases,8 showed the sign of UVL after receiving initial two ITGs and were not given any more intratympanic injections,and the other 2 patients were administered three ITGs. A two-year follow-up revealed that complete and substantial vertigo control was achieved in 9 cases,and limited vertigo control in 1 patient. Hearing level was lowered in 2 patients. The posture stability and functional level scores were improved. Our study showed that the modified titration protocol of ITG at a low dose could effectively control vertigo in patients with unilateral intractable MD.

文摘The etiology and underlying mechanism of Meniere's disease(MD)development are still unknown,although inflammation and autoimmunity have been implicated as underlying mechanisms.The human endolymphatic sac(ES)has been reported to have innate and adaptive immune capacity in local immune reactions.In vivo demonstration of inflammation of the ES in patients with MD is missing in the literature.We report the case of a 47-year-old female patient diagnosed with unilateral MD with genetic variants and cytokine markers indicating inflammation and vascular congestion of the ES.Endolymphatic hydrops in the right cochlea(grade 2)and vestibulum(grade 3)were detected using MRI.She carried heterozygous variants in MEFV(c.442G>C),IRF8(c.1157G>T),ADA(c.445C>T),PEPD(c.151G>A),NBAS(c.4049T>C),CSF2RB(c.2222C>T),HPS6(c.277G>T),IL2RB(c.1109C>T),IL12RB1(c.1384G>T),IL17RC(c.260_271del GCAAGAGC TGGG),LIG1(c.746G>A),RAG1(c.650C>A),and SLX4(c.1258G>C,c.5072A>G).In the serum,the levels of granulocyte colony-stimulating factor(G-CSF),macrophage inflammatory protein 1a,and IL7 were significantly elevated,and the level of IL2Ra was reduced.Intratympanic administration of dexamethasone temporarily alleviated her hearing loss.Her vertigo was significantly relieved but remained slight after ES administration of corticosteroids.
文摘BACKGROUND Coronary artery disease(CAD)is a leading cause of global cardiovascular morta-lity.Refractory angina pectoris,a manifestation of CAD,requires effective drug treatments.Pericarpium Trichosanthis injection,a traditional Chinese medicine,improves cardiovascular symptoms,while nicorandil alleviates spasms and angina.Both have potential in treating CAD.AIM To investigate the therapeutic effects of combining Pericarpium Trichosanthis injection and nicorandil in elderly patients suffering from refractory angina caused by coronary heart disease.METHODS A retrospective analysis was conducted on the data of 130 patients diagnosed with refractory coronary heart disease.Based on the different treatment regimens administered during hospitalization,the patients were divided into a control group(58 cases)and a study group(72 cases).The control group received conven-tional treatment,which included aspirin,statins,and nitrate vasodilators.In addition to the conventional medication,the study group received a combination treatment of Pericarpium Trichosanthis injection and nicorandil.RESULTS After treatment,the study group showed significantly higher left ventricular ejection fraction and cardiac output,and lower brain natriuretic peptide and C-reactive protein levels compared to the control group.The study group also exhibited improvements in angina,quality of life,exercise endurance,and lipid profiles.Multivariate logistic regression analysis revealed a relationship of lipid levels and heart function with the combined treatment.Some patients in the study group experienced headaches during treatment,but no significant adverse reactions were observed.Follow-up showed that the treatment was well-tolerated,with no drug-related adverse reactions detected.CONCLUSION Combination of Pericarpium Trichosanthis injection and nicorandil is more effective than conventional treatment in improving symptoms and heart function in elderly patients with refractory angina pectoris.

文摘The aim of the present work was to show the sustainability of fibrin sealant in releasing dexamethasone and adjust the protocol for clinical application of the novel method in the treatment of Meniere’s disease (MD) and sudden sensorineural hearing loss (SSHL).Gelation occurred shortly after mixing dexamethasone-containing fibrinogen with thrombin.Dexamethasone was constantly released for at least 16 d at a stable level after 7d in protocol 1 (low-dose),while it was robustly released within 4 d and slowed afterward until 10 d in protocol 2(high-dose).There were significant differences among the time points in Protocol 2 (p<0.01,ANOVA),and the exponential model with the formula y=15.299*e~(-0.483*t) fits the association.The estimated concentration of dexamethasone released on 7 d in protocol 2 was slightly lower than that observed in protocol 1.The fibrin sealant is capable of constantly releasing dexamethasone with adjustable dynamics.Targeted and minimally invasive administration of the material can be achieved in the clinic by sequential injections of the fluids using a soft-tipped catheter.
文摘Objective:To assess the effect of selective serotonin reuptake inhibitors(SSRIs)and tricyclic antidepressants(TCAs)in reducing vertigo,tinnitus,and hearing loss among patients with Meniere's disease(MD).Data Sources:The following databases were utilized in this scoping review:Ovid Medline,PubMed-NCBI,CINAHL,Cochrane Library,Web of Science,and Clinicaltrials.gov.Method:Studies were identified through the following search phrases:"serotonin specific reuptake inhibitors"OR"tricyclic antidepressants"AND"Meniere's disease."References from included manuscripts were examined for possible inclusion of additional studies.Results:The literature search yielded 23 results,which were screened by three independent reviewers.Seventeen studies and three duplicates were excluded.An examination of references from the included studies yielded two additional publications.A total of four published studies assessing SSRIs and TCAs among 147 patients with MD were ultimately included.Four studies described significant reductions in vertigo attack frequency among patients treated with either SSRIs or TCAs compared to their pretreatment baseline.Three studies assessed the drugs'effects on hearing,of which none found a significant difference among patients treated with SSRIs or TCAs.One study found a significant decrease in patient-reported tinnitus following treatment with TCAs or SSRIs compared to their pretreatment baseline.Conclusions:Data exploring SSRIs and TCAs among patients with MD suggests that these medications may reduce the frequency of tinnitus and vertigo,although there was significant heterogeneity in outcome reporting.There remains a need for larger-scale prospective studies that emphasize objective data to evaluate their effective-ness in reducing common MD symptoms.
