BACKGROUND AND PURPOSE: The elderly population and the prevalence of stroke, dementia, and Parkinson's disease are increasing rapidly in Korea. The aim of this study was to establish the length of stay (LOS) for neurological geriatric diseases, and analyze this parameteraccording to healthcare institutions. METHODS: We used data from the Health Insurance Review and Assessment Service from 2003 to 2007. Nineteen neurological geriatric diseases were classified into four groups: dementia, cerebral hemorrhage, cerebral infarction, and Parkinson's disease. LOS was analyzed according to gender, age, insurance type, disease group, and type of healthcare institution. RESULTS: The LOS for neurological geriatric diseases lengthened from 5,550,193 days (10.8% of the total National Health Insurance admission days) in 2003 to 14,749,671 days (19.7%) in 2007. The mean LOS was 40.8 days in 2003, and lengthened to 71.2 days in 2007. After stratification by disease group, the mean LOS for long-term-care hospitals lengthened by 1.43 times (from 81.7 to 116.6 days) in the cerebral infarction group, 1.35 times (from 85.6 to 115.2 days) in the cerebral hemorrhage group, and 1.28 times (from 82.7 to 105.7 days) in the Parkinson's disease group. CONCLUSIONS: The LOS for neurological geriatric diseases has lengthened markedly, which isdue to an increasesin the number of hospitalized patients and the mean LOS, which have increased most rapidly in long-term-care hospitals. These results may be useful in developing geriatric health policies.

Background: The purpose of this study is to investigate the tooth whitening effect of Listerine Healthy White and provide effective management of extrinsic discoloration by comparing the whitening effects of existing whitening products. Methods: The included study four groups: those using whitening gel, whitening toothpaste, and Listerine Healthy White and a control using artificial saliva. Each group received 40 bovine tooth specimens, which were stained with commonly consumed tooth-coloring-inducing foods; black tea, black coffee, and instant noodles for 72 hours. The specimens were treated with tooth whitening materials for 5 weeks, after which the lightness (L*) was measured weekly using a spectrophotometer. Results: There was a significant difference in lightness among the groups between the 1st and 5th week of treatment for all tooth-coloring-inducing foods (p＜0.05). When comparing the changes in lightness values from before whitening to the 5th week of whitening for all tooth-coloring-inducing foods, the order of change was as follows: whitening gel, whitening toothpaste, Listerine Healthy White, and artificial saliva. Listerine Healthy White showed a significant whitening effect for all toothcoloring-inducing foods (p＜0.05). Particularly, changes in lightness values for specimens stained by black tea after 5 weeks of whitening were in the following order: whitening gel (21.72), whitening toothpaste (14.89), Listerine Healthy White (12.91), and artificial saliva (3.85). For specimens stained by black coffee, the changes in lightness values were in the following order: whitening gel (12.99), whitening toothpaste (9.66), Listerine Healthy White (7.91), and artificial saliva (3.12). Lastly, changes in lightness values for specimens stained by instant noodles were as follows: whitening gel (10.84), whitening toothpaste (9.85), Listerine Healthy White (7.71), and artificial saliva (2.61). Conclusion Listerine Healthy White exhibits continuous whitening effects over time, and for consumers seeking convenient ways to achieve tooth whitening effects at home, consistent use of Listerine Healthy White is recommended.

BACKGROUND/AIMS: Helicobacter pylori (H. pylori) transmission route is not yet clearly understood. Isolating H. pylori from stool, saliva, and vomitus is very difficult. However, H. pylori could be cultured from feces in the setting of rapid gastrointestinal tract transit. The aim of this study was to isolate H. pylori by culture and PCR in the rectum and terminal ileum during colonoscopy. METHODS: Twenty subjects with positive UBT (urea breath test) were included. We performed polymerase chain reaction (PCR) test and culture of H. pylori with the rectal fluid and terminal ileal fluid during colonoscopy. RESULTS: H. pylori was cultured with rectal fluid from 9 (45.0%) of 20 subjects and with ileal fluid from 11 (55.0%) of 20 subjects. H. pylori was a little more frequently cultured from the terminal ileal fluid than the rectal fluid without statistical significance (p>0.05). PCR test detected flaA (16/20, 80.0% and 17/20, 85.0%), 16S rRNA gene (16/20, 80.0% and 17/20, 85.0%), cagA (10/20, 50.0% and 12/20, 60.0%), and ureC (9/20, 45% and 11/20, 54.5%) from the rectal fluid and the terminal ileal fluid, respectively. The specificity and sensitivity of ureC were 100%. CONCLUSIONS: H. pylori could be cultured from the rectal fluid and terminal ileal fluid in the setting of rapid gastrointestinal tract transit. These results suggest of fecal-oral transmission of H. pylori.
