PURPOSE: This study was conducted to determine the effects of a fall prevention program on knowledge, efficacy, and prevention behavior of falls among the low-income elderly. METHODS: This study used a nonequivalent control group pre and post test quasi-experimental research design. The study was conducted from August to October, 2008 with 20 subjects in the experimental group and 22 in the control group who were registered at the public health center of S District in D City. RESULTS: Hypothesis 1 "The experimental group that participated in the fall prevention program will show a higher degree of knowledge about falls than the control group" was supported. Hypothesis 2 "The experimental group will have a higher degree of self-efficacy of falls than the control group" was not supported. Hypothesis 3 "The experimental group will report fall prevention behavior more frequently than the control group" was supported. CONCLUSION: It was verified that the fall prevention program in this study was an effective intervention to improve knowledge about falls and fall prevention behaviors among the low-income elderly. The results can be used as part of an intervention to prevent falls for the vulnerable elderly such as the low-income elderly.

PURPOSE: Kissing contusion between the posterolateral tibial plateau and lateral femoral condyle is frequently found in association with a tear of the anterior cruciate liagment (ACL). The purpose of this study was to determine which ligamentous and meniscal tears are associated with kissing contusion. MATERIALS AND METHODS: We retrospectively reviewed the findings depicted by 323 consecutive MR images of the knee and confirmed at arthroscopy. For the diagnosis of disruption, ligaments, medial menisci (MM) and lateral menisci (LM) were evaluated using accepted criteria. We compared the prevalence and location of meniscal and ligamentous tears between group I (44 knees with kissing contusion) and group II (279 knees without kissing contusion). For statistical analysis the chi-square test was used. RESULTS: ACLs were torn in all 44 knees (100%) with kissing contusion, and 78 (28%) of 279 without kissing contusion. There were ten medial collateral ligament (MCL) tears (23%) in group I, and 17 MCL tears (6%), five lateral collateral ligament (LCL) tears (2%) and ten posterior cruciate ligament (PCL) tears (4%) in group II. In group I, meniscal tears were found in 22 MM (50%) and in 19 LM (43%), while in group II, they occurred in 128 MM (46%) and 128 LM (46%). In group I, 17 (77%) of 22 MM tears and 13 (68%) of 19 LM tears were located in the posterior horn, while in group II, the corresponding figures were 97/128 (76%) and 60 of 128 (47%). The differing prevalence of ACL and MCL tears between the groups was statistically significant (p<0.05), but differences in the prevalence and location of meniscal tears were not (p>0.05). CONCLUSION: Although kissing contusion was a highly specific sign of ACL tears, its presence was also significant among MCL tears. There was no signifficant difference in meniscal tears with or without kissing contusion.

PURPOSE: To evaluate MRI findings of lateral lumbar disc herniations (LLDHs) and to determine whether those correlate with clinical symptoms. MATERIALS AND METHODS: The study included 105 patients with LLDHs that were diagnosed by MRI. The distribution and location of the LLDHs (foraminal, extraforaminal, and foraminal and extraforaminal), the displacement of adjacent nerves, and the detection rate of LLDHs from axial and sagittal images were reviewed retrospectively by two radiologists. 36 patients were included in evaluating whether location of LLDHs and displacement of adjacent nerve correlate with radiculopathy. RESULTS: The distributions of the LLDHs were 3.4% at L1-2, 14.4% at L2-3, 33% at L3-4, 33% at L4-5, and 16.9% at L5-S1. The locations were foraminal in 38.6% of cases, extraforaminal in 45.4% of cases, and foraminal and extraforaminal in 16% of cases. In addition, 77.3% of the diagnosed LLDH cases displaced the adjacent nerve. The detection rates of LLDHs in the axial and sagittal images were 100% and 77.3%, respectively. In 36 patients, 47.4% had radiculopathy related to LLDHs. Location of LLDHs and displacement of adjacent nerve had no statistically significant difference between patients with or without radiculopathy. CONCLUSION: MRI is an effective method for evaluating the location of LLDHs and their influence on adjacent nerves. The axial image is more important than the sagittal image in diagnosing LLDHs. The location of LLDHs and the displacement of adjacent nerve were not found to be related to radiculopathy.

Pillows are known to contain significant levels of indoor allergens and endotoxin, that are of importance to house dust mite sensitized asthmatics. Buckwheat pillows are commonly used in Korea. We studied the levels of the house dust mite allergen, Der f 1, and endotoxin on new synthetic and buckwheat pillows and their accumulation over three months. Endotoxin levels were significantly higher on new buckwheat pillows compared to synthetic pillows; geometric mean levels (95% CI) were 60,950 EU/g (30,270-122,700) and 4,887 EU/g (2,570-9,311) respectively (p<0.001). No Der f 1 was detected on the new pillows. After three months Der f 1 levels were similar on buckwheat and synthetic pillows, geometric mean levels (95% CI) were 1.16 microgram/g (0.02-8.13) and 1.08 microgram/g (0.19-1.68) respectively. These results indicate that buckwheat pillows are a source of very high endotoxin levels that may be of relevance to asthma severity of atopic asthmatics.

BACKGROUND: This study was designed to evaluate the role of KATP channel activation and change of monophasic action potential duration on cardioprotective effect of ischemic preconditioning in cat. METHODS: 34 cats were divided into 4 groups: control (n=10), ischemic preconditioning(n=8), glibenclamide pre-treated(n=8) and nicorandil pre-treated group(n=8). Ischemic preconditioning was done in ischemic preconditioning and glibenclamide pre-treated groups by 3 episodes of 5 min ischemia and 10 min reperfusion. All subjects underwent 40 min of ischemia and 40 min reperfusion. The KATP channel antagonist glibenclamide was given as intravenous bolus (0.5mg/kg) 10 min before ischemic precondtioning and infused (5 microgram/min) during ischemic preconditioning. Nicorandil, a KATP channel opener was injected as intravenous bolus (0.5mg/kg) before 40 min ischemic procedure. Monophasic action potential duration at 50% repolarization(MAP50) was measured in the ischemic and non-ischemic area respectively by epicardial probe throughout the experiment. The effects of ischemic preconditioning were determined by infarct size (% area at risk). RESULTS: Ischemic preconditioning or pretreatment with nicorandil prior to 40 min ischemia demonstrated a significant reduction in infarct size(26.6+/-7%, 33+/-8% infarction of the risk zone, respectively, p<0.01, p<0.05 vs. control) with respect to control(42+/-7% infarction of the risk zone). Pretreatment with glibenclamide abolished the effect of ischemic preconditioning(40+/-8% infarction of the risk zone, p=NS vs. control) Ischemic preconditioning group exhibited a significant reduction of ischemic area MAP50 duration in the ischemic area during preconditioning; at first preconditioning 123+/-9msec vs. 137+/-19msec control(p=NS), at second preconditioning 105+/-16msec vs. 140+/-19msec control(p<0.01), at third preconditioning 109+/-15msec vs. 138+/-19msec control(p<0.05). Pretreatment with glibenclamide prevented the reduction of MAP50 in the ischemic area during ischemic preconditioning. During 40 minutes ischemia, MAP50 shortening was more pronounced in the preconditioned group than in control group; at 10 min 85+/-22 msec vs. 131+/-31msec control(p<0.05), at 20 min 88+/-21msec vs. 130+/-32msec control(p<0.05), and at 30 min 103+/-24msec vs. 136+/-30msec control(p<0.05). This shortening effect was prevented by glibenclamide pretreatment. Nicorandil pretreatment pronounced the ischemic shortening of MAP50 in ischemic area and the nicorandil effect was most significant during early ischemic period; at 10 min 97+/-21msec(p<0.05 vs. control), at 20 min 104+/-32msec (p=NS vs. control), and at 30 min 134+/-28msec(p=NS vs. control). MAP50 measured in non-ischemic area was not significantly different between groups. CONCLUSION: We conclude that KATP channel activation and monophasic action potential duration shortening play a important role in myocardial protection during ischemic injury.
