PURPOSE: This is a qualitative study to identify dimensions of long-term care hospital care quality that provide high-level medical services for long-term care patients in Korea. METHODS: Service consumers and providers were interviewed, and collected data were analyzed into thesis, type and dimension. The focus group method was applied to two provider groups and individual interview was applied to two persons who had experienced a long-term care hospital. RESULTS: The results of analyzing the comsumers and providers was integrated into 8 dimensions: physical environment, staff, clinical care and nursing, multiplicity of activity program, atmosphere, interaction with family, nutrition, and quality improvement system. CONCLUSION: The dimensions of long-term care hospital care quality from this study can be used as a basis of quality indicators. Quantitative studies to test these dimensions are required for establishing quality management systems.

PURPOSE: This in vitro study was performed to assess the adherence of Porphyromonas gingivalis to a resorbable blast media (RBM) titanium surface pretreated with an ultrasonic scaler or toothbrush and to evaluate the effects of the treatment of the RBM titanium discs on the bacterial removal efficiency of brushing by crystal violet assay and scanning electron microscopy. METHODS: RBM titanium discs were pretreated with one of several ultrasonic scaler tips or cleaned with a toothbrush. Then the titanium discs were incubated with P. gingivalis and the quantity of adherent bacteria was compared. The disc surfaces incubated with bacteria were brushed with a toothbrush with dentifrice. Bacteria remaining on the disc surfaces were quantified. RESULTS: A change in morphology of the surface of the RBM titanium discs after different treatments was noted. There were no significant differences in the adherence of bacteria on the pretreated discs according to the treatment modality. Pretreatment with various instruments did not produce significant differences in the bacterial removal efficiency of brushing with dentifrice. CONCLUSIONS: Within the limits of this study, various types of mechanical instrumentation were shown to cause mechanical changes on the RBM titanium surface but did not show a significant influence on the adherence of bacteria and removal efficiency of brushing.

PURPOSE: This study was conducted to investigate the effects of variations in arm swing during gait on movement of the trunk and pelvis. During the gait task, the angle of the trunk and pelvic rotation were analyzed according to arm swing conditions. METHODS: Seventeen healthy males participated in this study. All subjects were analyzed for gait on a treadmill three times each under three different types of arm swing conditions – natural arm swing, restricted arm swing using a phone, restricted swing in both arms. 3-D motion analysis systems were used to collect and analyze the kinematic data of trunk and pelvic movements, and repeated one-way ANOVA was used to compare the trunk and pelvic kinematic data and symmetry index. The level of significance was α=0.05. RESULTS: The results showed kinematic differences in trunk and pelvic during gait based on the arm swing conditions. Specifically, there were significant differences in trunk rotation, left and right trunk rotation and symmetry index of trunk rotation during gait among the three arm swing conditions. ROM was used to calculate a symmetry index (SI) based on the average left and right trunk rotation in which a value closer to zero indicated better balance. The SI obtained for arm swing restricted with the phone was closer to –1 than the other conditions. CONCLUSION: Restricted arm swing due to use of a phone had the possibility to induce instability of postural control while walking, which could be seen to suggest a risk of falling during gait.

OBJECTIVES: We aimed to provide standard data of the individual tests in 7MS that could generalized for Korean elderly according to age and education. We also evaluated diagnostic efficacy of each test in 7MS. METHODS: Data on demographic characteristics of 311 normals were gathered for comparison. We also assessed two differences between normal and dementia group in individual tests of 7MS. RESULTS: All individual tests of 7MS showed significant differences in sex, age, and education, except for ECR. But there were no significant differences in sex controlling age and education. As a result of ROC curve, the ability of the ECR test to discriminate between AD and normal subject appeared superior. The scores of the individual tests of 7MS among CDR 0.5 and 1 group and normal group were compared. It was also found that the ECR test stands out among 7MS tests. CONCLUSION: The 7MS, particularly ECR, had the highest sensitivity and specificity for diagnosis of AD as well as early dementia. It suggests that the individual tests of 7MS are useful to predict early dementia, without using the complex logistic regression equation.

Critical valvular aortic stenosis(AS) is a life threatening congenital heart anomaly in neonates or infants. The main cause of death is rapidly progressing left ventricular failure. The treatment goal of critical AS is to save left ventricular function early. Before the 1980s, the preferred treatment was surgical valvotomy, however, that operative method had a high mortality rate and risk of re- procedure. These surgical problems encouraged balloon aortic valvuloplasty technique for initial life saving. There were some vascular approaches for balloon aortic valvuloplasty(e.g. femoral artery and vein, umbilical artery and vein, carotid artery). Each approach has some advantages and disadvantages. Balloon aortic valvuloplasty through the right carotid artery makes access to the aortic valve easy, has less vascular complication, and short procedure time and effect of saving femoral artery for reballooning. We had three cases of transcarotid balloon aortic valvuloplasty in infants with critical AS. In our long-term follow up, we had good results, except carotid artery thrombosis in one case. We report the first three Korean cases of balloon aortic valvuloplasty though carotid artery cutdown procedure for critical AS with a brief review of literatures.

PURPOSE: The purposes of this study were to evaluate the plain radiologic findings of the childhood intussusception and to evaluate the role of plain abdominal films in predicting the success of air or barium reduction. SUBJECTS AND METHODS: We retrospectively reviewed 140 cases with the diagnosis of intussusception in children. The radiological signs that included soft tissue mass, dilatation of small bowel suggesting obstruction, crescent sign, and target sign were evaluated in terms of frequency. The relationship between radiological findings and outcome of reduction was analyzed. The site of soft tissue mass or crescent sign seen on plain radiographs was correlated with the position of the apex of the intussusceptum seen at the beginning of barium enema. The degree of dilated small bowel was evaluated by calculating the proportion of air-filled small bowel occupying peritoneal cavity and measuring the maximal diameter of dilated bowel lumen. The radiological finding for small bowel obstruction is determined by observation of the degree of small bowel dilatation and/or air-fulid levels. RESULTS: Ninety-two cases out of 140 showed one or more radiographic signs. Two most common signs were soft tissue mass and small bowel obstruction. The success rate of air or barium reduction was significantly lower in patients with most severe degree of dilatation of small bowel and/or more than 7 air-fulid levels on erect view. The suspected location of intussusception on plain radiographs correlated well with the true location of intussusception seen in the first few seconds of barium reduction. CONCLUSION: Plain abdominal radiography is useful in the diagnosis of intussusception and provides helpful informations for the reduction procedure as well as for the exclusion of the contraindications such as bowel perforation.

BACKGROUND/OBJECTIVES: The immigrant population has grown considerably in South Korea since the early 1990s due to international marriages. Dietary changes in immigrants are an important issue, because they are related to health and disease patterns. This study was conducted to compare changes in dietary intake between baseline and follow-up periods. SUBJECTS/METHODS: Two hundreds thirty three Vietnamese female married immigrants. Baseline data were collected during 2006-2009, and the follow-up data were collected during 2008 and 2010. Food consumption was assessed using a 1-day 24-hour recall. RESULTS: The amount of the total food consumed (P < 0.001) including that of cereals (P = 0.004), vegetables (P = 0.003), and fruits (P = 0.002) decreased at follow-up compared to that at baseline, whereas consumption of milk and dairy products increased (P = 0.004). Accordingly, the overall energy and nutrient intake decreased at follow-up, including carbohydrates (P = 0.012), protein (P = 0.021), fiber (P = 0.008), iron (P = 0.009), zinc (P = 0.006), and folate (P = 0.002). Among various anthropometric and biochemical variables, mean skeletal muscle mass decreased (P = 0.012), plasma high density lipoprotein-cholesterol increased, (P = 0.020) and high sensitivity C-reactive protein decreased at follow-up (P < 0.001). CONCLUSIONS: A long-term follow-up study is needed to investigate the association between changes in food and nutrient intake and anthropometric and biochemical variables in these Vietnamese female marriage immigrants.

BACKGROUND AND OBJECTIVES: To determine the anatomic position of the inferior alveolar nerve (IAN) canal in patients with mandibular prognathism using the cone-beam CT (CBCT). MATERIALS AND METHODS: Fifty rami from 25 patients were evaluated. The images were taken by i-CAT and reconstructed 3-dimensionally using the Simplant 11 program. The linear distances between the IAN canal to the buccal cortex (a, a* and a**), from the IAN canal to the alveolar crest (b and b*) and the anterior margin (b**) and finally the buccal cortical thickness (c, c* and c**) were measured at three reference planes (VP, OP and HP). RESULTS: On the left side, the average distance of a, b and c were 7.12, 15.96 and 3.60 mm on the VP plane, respectively. On the OP, the distance of a*, b* and c* was 6.11, 8.83 and 2.63 mm. For the HP, the distance of a**, b** and c** was 4.84, 10.11 and 2.30 mm. On the right side, the distance of a, b and c, on the VP, was 7.10, 16.13 and 3.42 mm, respectively. On the OP, the distance of a*, b* and c* was 4.77, 8.75 and 2.68 mm. On the HP, the distance of a*, b* and c** was 4.55, 9.84 and 2.38 mm. Regarding the difference between genders, the distance in male's was longer than female's on the VP (p=0.019), and was thicker in males than females on the HP (p=0.002). CONCLUSION: The CBCT data provided accurate information about the location and course of the IAN.

PURPOSE: The purpose of this trial was to determine whether salbtamol and budesonide combined inhalation therapy is more efficacious than conservative treatment for admitted infants with bronchiolitis in early phase. METHODS: The study subjects were 72 infants admitted to Sun Hospital in Taejeon from July 1994 to June 1995, whose age from 1 month to 12 months with clinical diagnosis of bronchiolitis. Infants were randomly assigned to different three treatment groups as follw: Group C: 21 infants who received conservative treatment with oxygen (4liter/min); Group A: 23 infants who received salbutamol (0.1mg/kg) inhalation therapy using ultrasonic nebulizer at 6 hours interval add to conservative therapy; Group B: 28 infants who received budesonide (0.1mg/kg) inhalation therapy with above mentioned treatment at 12 hours interval. Then, infants were analyzed by comparison of clinical score, repiratory rate at time order of entry, 12 hours, 24 hours, 48 hours, 72 hours, and 5 days after treatment. We also compared ABGA of admission time to 24 hours after treatment of all groups and appreciate total hospital days of three groups. On follow up, same analyzing methods of comparison were used on 42 non-recurrent wheezing infants. RESULTS: The mean values of clinical score and respiratory rate were significantly improved in salbutamol and budesonide inhalation treatment group at 24 hours from medium of 6.1 60.7/min to 2.4, 42.3/min respectly. This effect was sustained thereafter. On the while, salbutamol inhalation group was significantly improved the clinical score and respiratory reate at 12 hours after therapy, but thereafter there was no obvious difference to conservative treatment. After then we exclude the recurrent infants and analyzed above mentioned items retrospectively. The improvement of clinical score and respiratory rate of salbutamol and budesonide inhalation therapy group was significant. Oxygenation was improved after 24hours of salbutamol and budesonide inhalation therapy. Total hospital stay was significantly reduced in salbutamol and budesonide inhalation group, and slightly reduced inthe salbutamol inhalation group. CONCLUSION: Infants with bronchiolitis treated with salbutamol and budesonide inhalation achieved better results in clinical score, repiratory rate PO2, and hospital days than no inhalation therapy. No reapiratory failure was occurred. So, this trial as treatment of bronchiolitis may be useful and effective therapy in those infants.
