Coma arousal procedure: A therapeutic intervention in the treatment of head injury

This study reports on the efficacy of a 'coma arousal procedure'. This procedure involved a programme of vigorous sensory stimulation administered to comatose patients by relatives using Comakits. An experimental group of 12 severely head-injured patients received the coma arousal procedure while a matched control group did not. Total duration of coma and weekly Glasgow Coma Scale Scores were recorded for the two groups. Results indicate that the total duration of coma was significantly shorter and that coma lightened more rapidly for the experimental group.     

Employment of Diabetics in a Post Office Region

In his article Employment of Diabetics John Lister (1982) concludedthat most diabetics are able to follow any occupation and thatthe majority of diabetics are reliable employees with good attendancerecords. This study summarizes the work experience of a groupof 50 diabetic employees who were identified in one Region ofthe Post Office. Their sickness absence records for a 5-yearperiod were compared with a matched, randomly selected controlgroup and with regional and national postal sickness absencefigures for the 4 years for which these are available. In oneof the study years, the diabetic group experienced fewer daysabsence per person per year than the national figures. Overthe whole study period the diabetic group experienced a greaternumber of spells and days of absence than the control group. This paper is the first of a series of three. The second paperdescribes the use of a questionnaire to obtain further informationon the range of duties being performed by diabetic employeesand gives some indications of the employment problems facingthis group. The final paper describes an investigation intomedical retirement and a mortality study of diabetic employeesover the period 1975–1984. Requests for reprints should be addressed to: Dr R. A.

Application of moist wound healing to the gerontologic population

During a five year period, approximately 150 elderly patients were treated with a water vapor and oxygen permeable membrane (VPM) in an open fashion. The following is important when treating elderly patients with VPM: xerosis or irritant dermatitis must be thoroughly treated before use of VPM as it will not adhere to abnormal skin; alcohol or acetone should not be used to prepare the treatment site as they cause irritation; VPM must not be stretched prior to placement as friction blisters occur in fragile, elderly skin; prior to removal, VPM should be soaked in soapy water or its surface rubbed lightly with alconol to break the adhesive bond to prevent stripping off epidermis; in patients with protein-calorie malnutrition, serum albumin should be monitored as large amounts of protein-rich fluid collect under VPM. VPM is a useful non-surgical approach to treating many ulcers in the elderly. Certain precautions must be taken to achieve optimum success in this population.     

Platelet secretory products may contribute to neuronal injury.

BACKGROUND: We do not fully understand the mechanisms for neuronal damage following cerebral arterial occlusion by a thrombus that consists mainly of platelets. The view that certain endogenous substances, such as glutamate, may also contribute to neuronal injury is now reasonably well established. Blood platelets are known to contain and secrete a number of substances that have been associated with neuronal dysfunction. Therefore, we hypothesize that a high concentration (approximately several thousand-fold higher than in plasma, in our estimation) of locally released platelet secretory products derived from the causative thrombus may contribute to neuronal injury and promote reactive gliosis. SUMMARY OF COMMENT: We have recently been able to report some direct support for this concept. When organotypic spinal cord cultures were exposed to platelet and platelet products, a significant reduction in the number and the size of the surviving neurons occurred in comparison with those in controls. We further observed that serotonin, a major platelet product, has neurotoxic properties. There may be other platelet components with similar effect. CONCLUSIONS: The hypothesis of platelet-mediated neurotoxicity gains some support from these recent in vitro findings. The concept could provide a new area of research in stroke, both at the clinical and basic levels.     

Swallowing food without chewing; a simple way to reduce postprandial glycaemia

1. The degree to which disruption by mastication affects the glycaemic response to four different carbohydrate foods was investigated in healthy human volunteers; each food was eaten by six subjects. 2. Subjects ate meals of sweetcorn, white rice, diced apple or potato on two occasions; on one occasion they chewed the food thoroughly, on the other occasion they swallowed each mouthful without chewing it. 3. When the foods were chewed the postprandial blood glucose levels rose to levels which varied according to the food ingested. 4. Swallowing without chewing reduced the glycaemic response to each food, achieving a similar effect as administration of viscous polysaccharides or 'slow-release' carbohydrates.     

Comparative clinical trial of fenticonazole ovule (600 mg) versus clotrimazole vaginal tablet (500 mg) in the treatment of symptomatic vaginal candidiasis

A multi-centre, randomized, single-blind, parallel-group clinical trial was undertaken in 50 patients (26 fenticonazole, 24 clotrimazole) with symptomatic vaginal candidiasis to compare the antifungal efficacy and tolerability of single-dose intra-vaginal treatment with a fenticonazole ovule (600 mg) or a clotrimazole vaginal tablet (500 mg). Assessment was by laboratory mycological investigation and symptomatic assessments for a period of 3 weeks from the day of treatment. Of the 50 patients, 43 (23 fenticonazole, 20 clotrimazole) returned for assessment 1 week after drug administration and 32 (17 fenticonazole, 15 clotrimazole) were re-assessed 3 weeks after drug administration. Both treatments resulted in very similar and highly significant improvements in symptoms, associated with disappearance of detectable Candida in approximately 70% of patients. There were no significant differences between treatments and no appreciable incidence of relapse during the 3-week period of observation. At the end of this period, 10 (59%) of 17 fenticonazole patients were totally disease-free, as compared with 10 (67%) of 15 patients after clotrimazole treatment. The cure rate observed was somewhat less than that previously seen when intra-vaginal cream formulations of the same two drugs were given on a multiple-dose basis. Both drugs were very well tolerated, with no reports of appreciable local or systemic adverse reactions to either drug.
