Stroke is one of the leading causes of death in Korea. According to the report from Korean national statistical office, the mortality rate of stroke was 73.2/100,000 persons in 2000. In Western countries, stroke mortality rates declined gradually from 1970, which accelerated markedly around 1990. Since then, there has been no further decrease in stroke mortality rates until now and the situation has been similar in Korea. In the past, hemorrhagic stroke in Korea similar to other Far East Asian countries. However, the ratio of hemorrhagic to ischemic stroke has been reversed since mid-1980s. This trend might be due to the westernization of diet and life style as well as better control of hypertension. The case fatality rate from one of the large hospital-based stroke registry was 7.2% within 30 days after the onset of acute ischemic stroke, which is similar to those of other series from western countries with an advanced medical care systems. It may be attributed to the inclusion of more asymptomatic or milder patients with small lesions detected by neuroimaging. Importantly, the delay of hospital visit after the onset of stroke and the lower compliance for secondary prevention remain serious problems in managing acute stroke in Korea. Despite recent advances in the diagnosis and management of stroke, there has not been a nationwide population-based epidemiologic data on stroke in Korea. Therefore the application of Internet technology to develop multi center cooperative hospital-based registry could be an important step toward a long-waited nationwide stroke registry.

Vascular dementia is defined as a clinical syndrome of acquired intellectual impairment resulting from a brain injury due to a cerebrovascular disorder. It incorporates various vascular pathophysiological mechanisms and changes in the brain, and has diverse cause and clinical manifestations. The main suptypes of vascular dementia include 1) multi-infarct dementia, 2) strategic infarct dementia, and 3) subcortical vascular dementia. Both multi-infarct dementia and strategic infarct dementia show heterogeneity in etiologies, changes of the brain, as well as clinical manifestations. On the contrary, subcortical vascular dementia is suggested to be a more homogenous group. To better understand the clinical features of vascular dementia, cases corresponding to each subtype of vascular dementia are briefly discussed this review.

Total hip replacement is an available rnethod of treatment for various causes of disabled hips in adults, especially in painful stiff hips. In many cases, malposition has led to degenrative changes in the opposite hip, the lumbar spine or knee, often with severe loss of function due to pain. Between March, 1979 and February, 1983, twenty hips in sixteen patients with painful and deformed hips were operated at Kosin Medical College, and we obtained relif of pain and increase of range of motion of the hip joints. Furthermore we found relife of adjacent joint pain in several cases, and in addition correction of inequality of leg lenght.

Gastric mucosa shows continuous changes in surface epithelium as well as inflammatory reaction by various substances from the outside and their metabolic products. Gastric mucosal lesions are proven to be associated with bacterial infection by the discovery of Heliobacter pylori(H. pylori) and many studies about histopathologic changes of gastric mucosa associated H. pylori infection has been advanced. It is known that H. pylori associated gastritis displays surface foveolar epithelial changes, such as cytoplasmic vacuolation, mucin loss, juxtaluminal cytoplasm erosion, epithelial denudation, and mucosal irregularity. There have been many studies that H. pylori infection is associated with intestinal metaplasia, gastric dysplasia, and carcinoma. Also chronic H. pylori infection with its induction of gastric lymphoid follicle has been implicated as a precursor of gastric lymphoma of the unique B-cell type that arises from mucosa-associated lymphoid tissue(MALT). However, these gastric mucosal changes are also observed in gastritis with other causes. In this study, we aimed to define specific histopathiologic findings associated with H. pylori infection. A total of 463 gastric biopsy specimens were reviewed. They were Helicobacter-associated gastritis and were divided as many (MH), a few (AH), and no (NH), according to the number of H. pylori. 210 (MH), 131 (AH), and 122 (NH) biopsy specimens were included. Lymphocytes, plasma cells in lamina propria, eosinophils and neutrophils in surface epithelium and crypt as well as lamina propria were graded from 0 to 3. Surface epithelial changes including cytoplasmic vacuolation, mucin loss, juxtaluminal erosion, epithelial denudation and mucosal irregrarity were observed in 200 of 210 cases(95%) in MH group, 34 of 131 cases(26%) in AH group, and 6 of 122 cases(5%) in NH group. This result indicates there is significant difference in surface epithelial changes according to the number of H. pylori(p<0.001). Severity of eosinophil, neutrophil, lymphocyte, and plasma cell infiltration is increased in proportion to the number of H. pylori. Especially, neutrophilic infiltration is not identified in 95 of 122 cases(78%) in NH group, whereas MH group shows severe infitration (grade 3) in 127 of 210 cases(61%), and no (grade 0) in 11 of 210 cases(5%). This data well explains that the severity of neutrophil infiltration is associated with, the degree of H. pylori infection in chronic active gastritis, with statistical significance. The prevalence of lymphoid follicle formation was 17 of 120 cases(14%) in NH group, 24 of 131 cases(18%) in AH group, and 52 of 210 cases(25%) in MH group. This shows that lymphoid follicle formation correlates with the number of H. pylori, but without statistical significance. The prevalence of intestinal metaplasia in NH, AH, and MH was 43 of 122 cases(35%), 46 of 131 cases(35%), and 69 of 210 cases(33%), showing no association between intestinal metaplasia and H. pylori. In summary, H. pylori associated gastritis dispays characteristic histopathological changes in gastric mucosa, in which surface epithelial changes and various inflammatory infiltrates are increased in proportion to the number of H. pylori. Especially vacuolization of surface foveolar epithelium, cryptitis, and crypt abscess are specific findings of H. pylori associated gastritis.
