In a nation-wide investigation, covering all the hearing centres in Sweden, a study was made of adaptation processes, subjective discomfort from tinnitus, subjective loudness of tinnitus and psychological complaints in 3372 subjects by means of a questionnaire. The most important predictors of discomfort from and adaptation to tinnitus were found to be the controllability and the degree of maskability by external sounds, i.e. the subject's coping abilities or internal-external locus of control. Increased control and masking effects from the environment imply a decrease in discomfort and better adaptation. The most important predictor of worsened subjective loudness of tinnitus was the duration of the tinnitus. That is, subjects who had had tinnitus for a longer time perceived the loudness as more intense. The psychosomatic factors which most strongly predicted increased discomfort from and decreased tolerance to tinnitus were depression and insomnia. These findings have theoretical and practical implications for the management and treatment of tinnitus.

The relation between Minnesota Multiphasic Personality Inventory (MMPI) and tinnitus was examined in 100 subjects with tinnitus disorders. The overall profile of tinnitus sufferers on the MMPI was normal. Higher scores on the depression scale were obtained in males. High hypochondria scores were related to long duration of tinnitus. High psychoasthenia scores were associated with hearing loss. Despite an analogy previously described between chronic pain and tinnitus, the psychometric parameters of tinnitus and of headaches are quite different.

The acute central nervous and cardiovascular effects of the local anesthetics ropivacaine and bupivacaine were compared in 12 volunteers in a randomized double-blind manner with use of intravenous infusions at a rate of 10 mg/min up to a maximal dose of 150 mg. The volunteers were all healthy men. They were familiarized with the central nervous system (CNS) toxic effects of local anesthetics by receiving a preliminary intravenous injection of lidocaine. The infusions of ropivacaine and bupivacaine were given not less than 7 days apart. CNS toxicity was identified by the CNS symptoms and the volunteers were told to request that the infusion be stopped when they felt definite but not severe symptoms of toxicity such as numbness of the mouth, lightheadedness, and tinnitus. In the absence of definite symptoms, the infusion was stopped after 150 mg had been given. Cardiovascular system (CVS) changes in conductivity and myocardial contractility were monitored using an interpretive electrocardiograph (which measured PR interval, QRS duration, and QT interval corrected for heart rate) and echocardiography (which measured left ventricular dimensions from which stroke volume and ejection fraction were calculated). Ropivacaine caused less CNS symptoms and was at least 25% less toxic than bupivacaine in regard to the dose tolerated. Both drugs increased heart rate and arterial pressure. Stroke volume and ejection fraction were reduced. There was no change in cardiac output. Although both drugs caused evidence of depression of conductivity and contractility, these appeared at lower dosage and lower plasma concentrations with bupivacaine than with ropivacaine.(ABSTRACT TRUNCATED AT 250 WORDS)

Tinnitus patients often complain of psychosomatic disorders and of problems in social life. We intended to prove the modulation of tinnitus perception by psychosocial factors. We examined 48 tinnitus patients, 35 with and 13 without hearing loss. A control group of 48 patients without tinnitus, without hearing disorder and without tumor disease was adapted to correspond to the tinnitus group in respect of age, sex and social factors. A quantitative assessment of complaints as well as of the intensity of depression was made via questionaires (Giessener Beschwerdebogen and Beck Depression Inventory). In tinnitus patients, we found a statistically significantly higher degree of complaints even for non-otological symptoms. They were statistically more depressive than the controls, but less than patients with endogenic depression usually are. Nevertheless, in tinnitus patients it seems to be reasonable to inquire after general symptoms of illness to assess whether cooperation with a psychiatrist is required before initiating somatic treatment.

The haemodynamic responses to laryngoscopy and intubation after induction of anaesthesia with thiopentone alone or in combination with 1.5 mg.kg-1 lidocaine and/or 1.5 or 3.0 microgram.kg-1 fentanyl were measured in 150 patients over 64 years of age to determine whether lidocaine, fentanyl or both lidocaine and fentanyl attenuated the pressor response. Fentanyl reduced the rises in systolic, diastolic and mean arterial pressures, heart rate, and rate pressure product and lidocaine decreased the rises in arterial blood pressure and rate pressure product (P less than 0.05). Fentanyl decreased the incidence of marked fluctuations in haemodynamic variables, often seen in geriatric patients (P less than 0.05). The haemodynamic effects of lidocaine and fentanyl were independent of each other. Complications occurred in all groups. Lidocaine-treated patients had fewer cardiac dysrhythmias (P less than 0.05) and 34 per cent of them had tinnitus. Fentanyl-treated patients had a higher incidence of hypotension (P less than 0.05). Respiratory depression developed in only one per cent of the fentanyl-treated patients. Both lidocaine and fentanyl are recommended adjuncts to induction of anaesthesia with thiopentone in geriatric patients.

Patients disabled by tinnitus show a high prevalence of major depression. Furthermore, tinnitus produces patterns of disability similar to those produced by major depression. To explore further this link between tinnitus and depression, and to investigate the efficacy of treating depression in the treatment of tinnitus, a single-blind, placebo-washout, nonrandomized pilot study of the tricyclic antidepressant nortriptyline (hydrochloride) was undertaken in disabled tinnitus patients who also met diagnostic criteria for major depression. Nineteen patients began the study, two responded to placebo, and two dropped out prior to completion. Fourteen considered their tinnitus improved, and 12 chose to continue taking nortriptyline after the study. Depression severity decreased, on the average, by 65% (p less than .0001). Tinnitus loudness measured by audiometric matching decreased by a mean of 10 dB or 50% (p less than .02). Self-reports of tinnitus loudness and severity, somatic and psychologic symptoms, and psychosocial dysfunction all showed significant improvement with treatment. These results suggest that what initially appears to be an irreversible otologic disability in these patients may be in large part a reversible psychiatric disability.

Symptoms of masked depression are often localised in the otorhinolaryngeal field. Headache, facial pain, dysphagia, burning sensations in the tongue, tinnitus, vertigo and voice and respiratory disorders were frequent complaints of 48 patients at our out-patient clinic between 1980 and 1985. After careful exclusion of organic disease, they proved to be due to endogenous depressive disorder. An increase in the number of such cases has been noted. One patient is described as an example of the problems of diagnosis.

A prospective assessment of psychiatric morbidity in a sample of 207 patients with inner ear disorders, attending an ENT clinic, was carried out. As a group, they were found to have higher psychiatric morbidity on the general health questionnaire (GHQ) than either normal samples or samples affected by other forms of physical disease. Within the sample tinnitus patients scored the highest, and presbyacusis patients the lowest. High GHQ scores predicted an exaggerated self-rating of symptom severity in a visual analogue scale. Past psychiatric history did not play a role in the development of psychiatric morbidity. Elderly subjects complained more often of fear of collapsing in the street but this was not related, as has been suggested, to the subsequent development of agoraphobic symptoms. Factor analysis of GHQ items for the 'cases' yielded 'depression', 'anxiety' and 'personality' factors. No correlation was found between these factors and the rest of the clinical variables. It is concluded that tinnitus shows the clearest association with psychiatric morbidity and hence merits detailed psychological analysis. Such a study has been started at Addenbrooke's Hospital.

In elderly patients an unilateral sensorineural hearing loss is frequently associated with a relatively more patent eustachian tube on the involved side. A simple method of investigation is observation under the operating microscope during tubal inflation by the patient. In right-handed patients the abnormally patent tube most often lay on the left side. Powerful self inflation in these patients induces acute hearing loss and vertigo. Acute hearing loss is commoner on the left side. The air bone gap is greater at higher frequencies due to mobility of the stapes, loosening of the incudal joints and the tympanic membrane. In contrast the air bone gap is greater at lower frequencies in otosclerosis or malleus head ankylosis. Minor degrees improve after self inflation is prohibited. In most patients with abnormally patent eustachian tubes further therapy is not necessary after the patient has received precise advice. In only about 20% of the cases is the patient disturbed by a feeling of fullness in the ear, autophony and tinnitus. After stabilisation of weight and blood pressure, a septoplasty with correction of the posterior turbinates may reduce the exspiratory resistance. The most drastic treatment is a collagen injection around the tube. Patients with depression should be treated appropriately.

Twenty patients with severe tinnitus who had undergone behavioural treatment, including applied relaxation and perceptual restructuring, were re-assessed 9 months after completion of treatment. Among the self-recorded variables, tinnitus loudness, discomfort from tinnitus, depression, and irritation, discomfort from tinnitus was the only variable which was still significantly reduced. As part of the 9-month follow-up assessment, the patients' recall of the loudness and discomfort from their tinnitus was studied. Correlations between original recordings and recall data were low.
