Electropalatography and the Linguagraph system.

This paper describes the technique of electropalatography and the development of Linguagraph, which is a user-friendly, clinical instrument, for measurement of tongue/palate contact, during speech. Linguagraph allows objective assessment of tongue function; appropriate targeting of therapy is therefore possible. Visual feedback is also provided, for therapy, and an objective measurement of outcome is easily obtained. Linguagraph was used, for both therapy and assessment, in a clinical trial. Technical aspects of Linguagraph and of the trial results are presented here. These suggest that the instrument will prove useful in the assessment and management of many speech disorders. Full clinical details of the trial are reported elsewhere.

The wavelength of light causing photophobia in migraine and tension-type headache between attacks.

OBJECTIVE: To ascertain the wavelength of light that patients with migraine and tension-type headache find uncomfortable between attacks. BACKGROUND: Photophobia is an abnormal perceptual sensitivity to light experienced by most patients with headache during and, also, between attacks. METHODS: We examined the discomfort threshold to light of low, medium, and high wavelengths in a group of patients with migraine (n=21), patients with tension-type headache (n=19), and healthy controls (n=21). RESULTS: The results indicate that the migraine group had significantly lower discomfort thresholds at the low (P=.001) and high (P=.031) wavelengths compared with both the tension-type headache and control groups; the latter two groups had similar average discomfort levels at these two wavelengths. With the medium wavelength, the control group had significantly higher discomfort thresholds than the migraine (P=.002) and tension-type headache (P=.031) groups; the latter two groups had similar discomfort levels at this wavelength. With unfiltered (white) light, the migraine group had the lowest discomfort threshold and the control group the highest (P=.026), whereas the tension-type headache group had an intermediate discomfort threshold. CONCLUSIONS: There were significant differences between migraineurs, patients with tension-type headache, and healthy controls in the wavelengths that are uncomfortable between attacks.

An instrument for the multiparameter assessment of speech.

This paper describes the development of SNORS+, a clinical, user-friendly instrument for measurement of the articulators during speech. The design criteria for the instrument were based upon a wide-ranging review of current practice and available techniques. SNORS+ allows objective assessment of the function and co-ordination of key articulators. Appropriate targeting of therapy is therefore possible. Visual feedback is provided, for therapy, and an objective measurement of outcome is easily obtained. Preliminary results are presented. These suggest that the instrument will prove extremely useful in the assessment and management of many speech disorders.

Photophobia and phonophobia in migraineurs between attacks.

This study investigated whether migraineurs are more sensitive to light and sound while headache-free than are healthy people. Fifty-two migraineurs (mean age 39 years) were selected using the International Headache Society diagnostic criteria for migraine. Forty-eight healthy controls were matched for age, sex, and race (mean age 36 years). Visual and auditory discomfort thresholds were measured by exposing subjects to increasing light and sound until they complained of discomfort. There were significant differences between groups in both the light discomfort threshold (P < 0.00005) and the hearing discomfort threshold (P < 0.0005). The thresholds for both were lower in the migraineurs. Overall, for both groups together, there was a significant negative correlation between light discomfort threshold and age (correlation coefficient -0.2276, P = 0.011), but not for the hearing discomfort threshold and age (P = 0.275). The results show that the migraineurs were significantly more sensitive to light and sound when headache-free than were healthy controls. The apparent increased intolerance to light in both groups together noted with increased age, did not apply to the migraine group.

Casemix for the elderly inpatient: Resource Utilization Groups (RUGs) validation project. Casemix for the Elderly Inpatient Working Group.

Current methods of contracting for patient treatment in the health service are not suitable for elderly patients with multiple pathology and functional impairment. This study examines Resource Utilization Groups (RUGs) for use in geriatric medicine in England and Wales, based on 1675 patients from 26 hospitals in eight health districts in England and Wales. Nurses completed a questionnaire on the clinical characteristics of patients required to allocate them to one of 44 RUG groups. Nurse/patient contact times were recorded over a 24-hour period. Therapist/patient contact times were recorded for a week. Data were analysed using analysis of variance with time as independent and RUG group as dependent variable. Variance explanation in excess of 45% was achieved in acute and rehabilitation wards. In long-stay wards, variance explanation (23%) was no better than ADL score alone. RUG-III could form the basis of a casemix system for geriatrics in England and Wales in acute and rehabilitation settings.

Service needs of stroke survivors and their informal carers: a pilot study.

This pilot study prepares the way for a controlled evaluation of counselling of disabled stroke survivors and their carers. It assesses feasibility of methods and outcome measures potentially useful in the main study. The study elicited information about the psychological, physical, social and service needs, and the feelings of stroke survivors and their informal carers. Twenty patients and their carers were interviewed separately in their own homes. Results describe research tools which were refined, and demonstrate several unmet needs in the psychosocial domain. The main findings were a requirement for more information about stroke and for counselling in relation to 'care' problems arising out of the disability of stroke disease and the changes in dependency produced.

Therapeutic progress--review XXIII. Are we making progress in the treatment of acute stroke?

The principal purpose of the treatment of acute stroke is to ensure that the quality of life of those affected is returned to as near normal as possible. Early nursing and physiotherapy are important components of effective management of acute stroke. It is not the intention of this review to examine these aspects which are so well described elsewhere (1). Instead, the theoretical and clinical bases for the various specific treatments advocated in recent years to reduce brain damage after ischaemic insult will be considered to serve as a guide for clinicians. Areas in this field where further research may prove rewarding are highlighted.

Isolation of eastern equine encephalitis virus from Aedes sollicitans during an epizootic in southern New Jersey.

Eastern equine encephalitis virus (EEE) was isolated from the salt marsh mosquito, Aedes sollicitans, collected from coastal areas of New Jersey on 3 occasions during the late summer and fall of 1982. The isolations were made at a time when local Culiseta melanura were either undergoing a population increase or exhibiting high levels of EEE virus. Although no human cases were reported during the epizootic period, the data lend support to the hypothesis that Ae. sollicitans is capable of functioning as an epidemic vector in the coastal areas of New Jersey where human cases of EEE have been most common.
