Delirium in clinical practice: experiences from a specialized delirium ward.

Geriatric patients with known dementia and suffering from an acute somatic disease are highly vulnerable to develop delirium. It is therefore essential to suspect and recognize delirium in these patients, especially in emergency wards. In the present study we evaluated activities on a dedicated delirium ward at a Swedish University Hospital.

The effect of antifibrinolytic agents on wound healing.

The effect on the tensile strength of healing wounds of 2 of the most commonly used antifibrinolytic substances, tranexamic acid and epsilon-aminocaproic acid, has been studied in white rats. 2 symmetrical linear lines were made on the dorsal skin, in 1 of which was injected 1 ml of the test solution. The incisions were closed with interrupted sutures, and after 7 days the animal was sacrificed, the wound excised and its tensile strength determined.

Plasminogen activators in human xenografted oro-pharyngeal squamous cell carcinomas.

Specimens of squamous cell carcinomas of the head and neck established as xenografted tumour lines on nude mice were examined by the fibrin slide method for the presence of plasminogen activator(s). The fibrinolytic activity was partly quenched by antibodies against the vessel-related tissue plasminogen activator and partly by antibodies against urokinase. The results indicate that inactive pre-urokinase in tumour tissue is to some degree activated when the tumour tissue is transplanted to the nude mice.

Laryngeal cancer, aryl hydrocarbon hydroxylase inducibility and smoking. A follow-up study.

In 58 cases with laryngeal cancer (10 supraglottic and 48 glottic), aryl hydrocarbon hydroxylase (AHH) inducibility and smoking habits were studied. All but 2 were smokers and most of them heavy tobacco consumers. The AHH levels were divided into high, intermediate and low groups and were compared to a large healthy control material also divided into the aforementioned groups.
