Descriptive analysis of emergency hospital admissions of patients with Alzheimer disease.

The aim of this project was to study the underlying reasons for emergency hospital admission of patients with dementia of the Alzheimer type (DAT) and their characteristics. This prospective 4-month study identified 118 patients with DAT, most of whom were referred to the two emergency departments of the Toulouse University Hospital. The two main reasons for admission were behavioral problems (26.3%) and falls (18.6%). Patients were generally at an advanced stage of the disease process and had substantial evidence of poor nutritional status and loss of activities of daily living ability. About one third of patients had already been admitted to the hospital for the same reasons in the preceding months. Psychotropic drugs predominated (71%) among the current medications taken by the patients and were mainly anxiolytics and neuroleptics. Finally, the discharge report indicated that medications were a contributing factor in the disorders of 25% of patients. We believe that improved information for caregivers and early management and treatment are essential to respond adequately to the problems raised by this population.

Absence of a role for selenium deficiency in the runting syndrome of broiler chickens in Australia.

The role of selenium deficiency in the etiology of the runting-stunting syndrome (RSS) of broiler chickens in Australia was investigated. Commercial broiler chickens maintained on selenium-deficient developed signs consistent with selenium deficiency of exudative diathesis and markedly reduced plasma glutathione peroxidase activity, but they did not develop pancreatic atrophy and fibrosis or elevated plasma amylase activity, which are the other lesions associated with RSS. Supplementation of the diets of birds from a RSS-susceptible flock with a mixture of selenium, vitamin E, cysteine, and sulfate had no effect on the incidence of runting in the treated birds. In field outbreaks of RSS there were no observable differences between affected and unaffected birds in the concentration of selenium in tissue samples. Furthermore, evidence is presented which suggests that in cases of RSS, pancreatic atrophy and elevations in plasma amylase precede reductions in plasma glutathione peroxidase activity.
