Implementing a computer-based electro-oculographic analysis system.

Electro-oculographic recordings of caloric-induced nystagmus were conducted in a number of normal and disordered subjects. On the basis of the results, implementation of a clinical measuring system is considered; this is based on the interbeat interval, selected in view of its favourable sensitivity and stability. Two stages of processing are involved; first, the determination of the interbeat intervals, second the analysis. The first stage has been implemented off-line on a general purpose computer and also, in on-line mode, by special purpose electronics. The second stage requires computer analysis. We have used the rank magnitude sequences of interbeat intervals as the basis of the analysis.

Caloric test with oculogyral illusion as response.

It has been demonstrated that the caloric test can be simplified further by making use of the oculogyral illusion. Since the test is conducted under conditions of optic fixation, this method probably also enhances the sensitivity of the caloric test. The reproducibility of the tests also appears high, at least in respect of measures of "canal paresis". When used in conjunction with other tests for detecting vestibular imbalance, e.g. examination for spontaneous and provocation nystagmus using Frenzel glasses, this OGI caloric test should provide a convenient procedure for the clinical examination of vestibular function.

A virological and epidemiological study of patients with acute hearing loss.

Virological and epidemiological data were examined in thirty-nine patients with acute hearing loss. The hearing loss was unilateral in thirty-one patients and bilateral in eight. There was a history of upper-respiratory-tract infection before onset of deafness in ten of the patients. Cases were more common in the autumn, with nineteen of the cases occurring in the 3 months from September to November. About half of the patients were 20-40 years old and half 46-73 years old; only one patient was aged less than 20 years. Antibodies to several common viruses were titrated, and there was evidence of recent infection by mumps virus in one case and by Mycoplasma pneumoniae in another. Although no evidence of recent virus infection was found in the remaining patients, it is suggested that the condition may be viral in origin and that further studies should be undertaken.

Gnathostomiasis. A case of otological interest.

A young Thai man was afflicted with neurognathostomiasis. The symptomatology was distinct from that of eosinophillic myeloencephalitis. In view of its neurootological flavor, it is proposed that this newly described symptomatology of neurognathostomiasis should be referred to as the neurootological gnathostomiatic syndrome(NOGS).

Subjective magnitude of auditory impairment. A pilot study.

A study of two samples (one in London, the other in Cairo) of patients who were suffering from an impairment of hearing showed that the subjective magnitude of auditory handicap was significantly correlated to the average hearing level at 2 000 Hz for the two ears. For both samples, the subjective magnitude of the auditory handicap was shown to be a power function of the hearing loss expressed in terms of the sound pressure corresponding to the threshold of hearing. The exponents in the power function applying to the two samples were similar. Age, sex and pain threshold did not influence the estimation of the subjective magnitude of auditory handicap in this study.
