Hospital-based stroke care in Ireland: results from one regional register.

BACKGROUND: Most patients with acute stroke are admitted to hospital. If stroke services in this country are to be improved, we need accurate and reliable information about the types of stroke patients being admitted, their present management and outcome. AIMS: To examine the demography, severity, level of investigation, length of stay, mortality and discharge location of prospectively identified consecutive stroke admissions to three general hospitals in South East Dublin. RESULTS: Three hundred and twenty nine consecutive stroke admissions to three general hospitals in South East Dublin were registered using the European Stroke Database over 50 weeks. The mean age was 73.3 years, whilst 20.1% patients were under 65 years. Prior to admission, 90% of patients were community dwelling with 14.9% of patients being dependent in activities of daily living. 22.4% of patients had some depression in level of consciousness on admission. The overall mortality rate was 26.1% whilst 136 (41.3%) were discharged home, 50 (15.2%) went to institutional care and 45 (13.7%) went to non general hospitals secondary rehabilitation units. The mean length of stay was 31.3 days. The combined poor outcome measure (mortality plus percentage of patients discharged to institutional care), was lower in one hospital compared to the other two hospitals (29.3% versus 44.65%, p > or = 0.05) probably reflecting case mix. Stroke accounted for 4.2% of all bed days in the major general hospital in this area. The overall CT scan rate was 84.5%, with 18.2% of CT scans showing a haemorrhagic component and two patients (0.8%) having brain tumours. Carotid doppler examinations were carried out in 37% of patients. CONCLUSION: The results demonstrate the high mortality and prolonged hospital stay for stroke patients in this area and emphasise the need for co-ordinated stroke care and regular audit to ensure most effective use of hospital resources.

Topical application of yeast extract accelerates the wound healing of diabetic mice.

Alcoholic extracts of yeast have been used as the active ingredient in medications under names such as "tissue or skin respiratory factor," Biodyne (Sperti Drug Co, Cincinnati, Ohio--now defunct), and live yeast cell derivative (LYCD). Beneficial clinical results from the use of LYCD have been reported for the treatment of burns, wounds, and hemorrhoids. The medicinal effects of LYCD have recently been localized to a protein fraction containing a mixture of several peptides. The effects of topical application of the peptide mixture on wounds were examined in diabetic mice, an animal model in which the healing process is disrupted and delayed. Full-thickness wounds were created on the backs of diabetic (DB) and nondiabetic (non-DB) mice. Half of the DB and non-DB mice were treated with 0.05 mL of LYCD after wounding and for 4 successive days. All other mice received vehicle. Wound areas were measured at Day 0 and at 2-day intervals. Mice were sacrificed at 3, 7, 10, 21, and 28 days postinjury. Differences in the extent and quality of healing appeared between DB mice receiving LYCD and DB mice receiving vehicle by day 10 (P < .0001). By 24 days postinjury, DB mice receiving LYCD had achieved 100% wound closure, whereas DB mice receiving vehicle had achieved only 31.4% wound closure. Histologic examination of wounds reflected improved wound healing in DB mice receiving LYCD as compared with those receiving vehicle. A topically applied yeast extract peptide mixture significantly attenuates wound closure and the degree of cellular reorganization of full-thickness excisional wounds of DB mice.
