ObjectivesTinnitus can induce disabling psychological suffering, requiring an integrative multimodal approach, combining neuromodulation and psychotherapeutic methods. We sought to evaluate the therapeutic efficacy and acceptability of Eye Movement Desensitization and Reprocessing (EMDR) in tinnitus.Materials and methodsThis was a single-center prospective non-comparative study. Inclusion criteria comprised: adult patient, with chronic tinnitus, Tinnitus Handicap Inventory (THI) score > 17, causing psychological distress motivating active treatment after ineffective “classic” treatment (combining advice, sound therapy and first-line drug treatment), and agreement to EMDR therapy. Therapeutic efficacy was defined by a decrease in THI or Visual Analog Scale (VAS) scores. Treatment acceptability was defined by the rate of included patients who completed therapy.ResultsThirty-eight patients were included. There was a significant reduction of 53.5% in THI score in 78.9% of patients (P < 0.0001; 64.8 ± 20.8 before versus 31.8 ± 24.7 after treatment), and of 51% in VAS score in 76.3% of patients (P < 0.0001; 7.24 ± 2.12 before versus 3.58 ± 2.03 after treatment). The treatment acceptability was 86.8%.ConclusionEMDR appeared to be an effective alternative that was acceptable to the majority of patients, after failure of “classic” first-line treatment, improving quality of life in tinnitus patients and thus relieving disability.  相似文献

Intractable tinnitus can lead to serious consequences. Study evidence indicates that the central nervous system is involved in generation and maintenance of chronic tinnitus and that tinnitus and other neurologic symptoms such as chronic pain may share similar mechanisms. Brain ablation and stimulation are used to treat chronic pain with success. Recent studies showed that ablation and stimulation in non-auditory areas resulted in tinnitus improvement. Deep brain stimulation (DBS) may be an alternative treatment for intractable tinnitus and deserves further study.  相似文献

Well-being (quality of life) in connection with hypertensive treatment   总被引:3,自引:0,他引:3  
Quality of life is often considered to equate how the medical treatment is subjectively perceived by the patient, but ought to include the total impact of the disease/treatment on the patient's emotional, physical, and social well-being. Recently, a proposal for a generally applicable definition of quality of life in health care was put forward. This definition includes general well-being, health, and welfare (external factors), as three fundamental components, and the definition is based on both objective and subjective judgments. General well-being is exclusively and expression of the individual's subjective experience and is based on his or her own qualitative evaluation of well-being in relation to condition, treatments, and experiences. Health is according to the proposed definition, judged both objectively (signs) and subjectively (symptoms). Apart from health and well-being, there is also reason to include objectively registrable factors at the welfare level (external factors) such as the consumption of medicines, number of days in hospital, length of sick leave, need of in-home care, etc. This review is an attempt to elucidate the effects of antihypertensive pharmacotherapy on the patient's general well-being. The topic will be discussed from several points of views (e.g., aims of antihypertensive treatment, occurrence of symptoms in the population, compliance with prescribed treatment, symptom inventories, the concept of quality of life.  相似文献

本文对从事京剧打击乐的55人(110耳)进行了听力调查及动态观察。利用图表进行对比分析,发现110耳中高频听力损伤89耳,占81%;语频听力损伤32耳,占29.1%;其中伴有高频耳鸣78耳,占70.9%。动态观察30人(60耳),均为永久性听阈阈移。高频听力损伤最早出现的频率是4kHz,并见典型“V”谷,符合噪声性聋的诊断。  相似文献

目的 分析主观症状及实验检查对早期干眼症患者诊断的意义。方法 对55例(109眼)已确诊的早期干眼症患者(无或仅伴有轻微体征)的临床症状及实验检查进行回顾性分析及比较。结果 患者中主观症状所占比率:干涩感94%,视疲劳感82%,异物感74%,明显高于其他症状(P〈0.05)。实验检查的阳性率:基础泪液分泌试验(Schirmer I test,SIt)35%,泪膜破裂时间检查(break-up time,BUT)85%,角结膜荧光素(fluorescent,FL)染色60%,其中BUT阳性率明显高于SIt和FL(P〈0.05)。结论 主观症状及实验检查可为早期干眼症诊断提供有利依据。  相似文献

Health-related quality of life (HQL) assessment in the clinical setting have distinguished subjective perceptions (e.g. well-being), signssymptoms of the disease, and functional capacity as three major components. The impact of short-term treatment for migraine attacks on these variables was evaluated in an open prospective 6-month study at the Gothenburg Migraine Clinic. Socio-economic factors, subjective symptoms, and general well-beingquality of life were evaluated by self-administered questionnaires in 99 patients with migraine with or without aura in accordance with the classification of the International Headache Society. Short-term treatment comprising conventional therapy or subcutaneous sumatriptan reduced number of days per month with migraine and absenteeism from work, migraine-associated symptoms, but did not significantly improve general well-being between attacks. Future assessment of the patients' HQL in accordance with this approach would enable us to consider all the advantages and disadvantages of current therapies of particular interest in the field of migraine.  相似文献

SUMMARY  The present study sought to investigate the meaning of subjectively good sleep, using a longitudinal and intraindividual design. Eight subjects slept in an isolation unit according to an irregular schedule of 6h sleeps and 1h naps, designed to give normal amounts of time in bed (1/3 of total), but variable sleep quality. Eight sleeps and eight naps were used for longitudinal simple and multiple regression analyses with standard polysomnographical sleep variables as predictors and subjective sleep quality as dependent variables. The results showed that subjective sleep quality (and related variables) was closely related to sleep efficiency, but not sleep stages. At least 87% efficiency was required for ratings of 'rather good' sleep. In addition, sleep quality ratings improved with closeness (of the awakening) to the circadian acrophase (17.00–21.00 hours) of the rectal temperature rhythm. The subjective ease of awakening differed from most other other variables in that it was related to low sleep efficiency. Objective and subjective homologues of sleep length and sleep latency showed high mean intraindividual correlations ( r = 0.55 and 0.64, respectively). It was concluded that objective measures of sleep continuity were closely reflected in perceived sleep quality and that sleep quality essentially means sleep continuity.  相似文献

Subjective health complaints without or with minimal somatic findings (pain, fatigue) are common and frequent reasons for encounter with the general practitioner and for long-term sickness leave and disability. The complaints are often attributed to the stressors of modern life. Is this true? We interviewed 120 Aborigine Mangyans (native population, M age = 33.5 years, 72.5% women) living under primitive conditions in the jungle of Mindoro, an island in the Philippines, and 101 persons living in a small coastal town on the same island (coastal population, M age = 33.8 years, 60.4% women). Both groups had more musculoskeletal complaints, fatigue, mood changes, and gastrointestinal complaints than a representative sample from the Norwegian population (N = 1,243). Our common subjective health complaints, therefore, are not specific for industrialized societies.  相似文献
