The goal of fracture treatment is to restore the patient to pre-injury function level. But the outcome assessment after orthopedic interventions has usually focused on physician-defined parameters of technical success, such as fracture union, alignment and range of motion rather than patient function and quality of life. However, the correlation among improvements in these parameters and functional status, psychosocial well being is inconsistent and weak in the elderly. Therefore authors assessed the functional status after surgical intervention of hip fractures in the elderly with functional recovery score(FRS). Independence in basic activities of daily living, in instrumental activities of daily living, in mobility, freedom from pain and intact memory were assessed in 133 hip fractures in the elderly. The hip fractures in the elderly resulted in 24.8% loss of function after the first year. The older the age, the more the loss of function after surgery of hip fractures. The more functional loss was observed in female patients and in patients with poor postoperative radiological results, but statistically insignificant (P>0.05). The more functional loss was observed in patients with underlying medical disease preoperatively and it was statistically significant (P<0.05). We recommend the evaluation of functional status in the elderly after hip fractures.

The effect of topical application on the number of S. mutans was tested in a group of 44 orthodontic patients (mean age, 12Y 3M). They were divided into 5 groups according to the method using NaF and SnF2. The number of S. mutans CFU were counted in stimulated saliva of each subject at baseline, and after one, two, three, and eight weeks. The following results were obtained. 1. In NaF rinsing group, and NaF topical application and NaF rinsing group, the number of S. mutans per ml saliva was not significantly changed. 2. In SnF2 topical application group, and SnF2 topical and NaF rinsing group, the number of S. mutans per ml saliva was significantly reduced. 3. After 8 weeks, there were no significant reduction of the number of S. mutans in comparison with baseline.

PURPOSE: The gastric cancer is most frequent malignant disease in Korea. With increase of GNP and social welfare, lot of people pay attention to that. But many of gastric cancer patients who were diagnosed, are advanced -stage III or more- case and produces poor result of treatment. Nowadays many surgeons report that the resection of cancer mass and radical lymph node dissection, which called systematic lymph node dissection, can increase the longterm survival rate and curability of patients. For this purpose Maruyama and his colleagues made a program to predict the 5 year survival rate, cause of death, and the status of lymph node metastases. We put the basic datas of pateints in AGC into Maruyama's program and compare its result to final histologic reports. We would check sesitivity, specificity, positive predictive value, negative predictive values between Maruyamas program and hitologic reports. MATERIALS AND METHODS: From Sep. 1995 to Sep. 1996, We operated 55 patients with gastric cancer with this program in GNUH. We checked the histopathologic reports and put the data into the prediction program. The datas were sex, age, maximal size of tumor, differentiation, gross type and location. We compared status of lymph node metastases, TNM stages between the reports of histopathology and that of predictive program. RESULTS: In early stages the sensitivity and specificity of the program showed poor result but in advanced stages did not. The distribution of lymph node metastasis showed a same pattern. The patterns of perigastric lymph node metastasis were somewhat different according to the location of tumor. But its significance was not confirmed. We analysed the metastaic rate between lymph node groups and compared with the results between two reports. The sensitivity, and negative predictive value were 100% in each groups, and positive predictive value was also high. CONCLUSION: The systematic lymph node dissection is an effective and safe procedure in the surgical treatment of gastric cancer. We suggest that the techniques should be standardized and popularized in Korea. This procedure will improve the survival rate of gastric cancer patients and decrease the local recurrence of gastric cancer.

BACKGROUND/OBJECTIVES: Cadmium is a toxic metal that is an occupational and environmental concern especially because of its human carcinogenicity; it induces serious adverse effects in various organs and tissues. Even low levels of exposure to cadmium could be harmful owing to its extremely long half-life in the body. Cadmium intoxication may be prevented by the consumption of dietary components that potentially reduce its accumulation in the body. Dietary chitosan is a polysaccharide derived from animal sources; it has been known for its ability to bind to divalent cations including cadmium, in addition to other beneficial effects including hypocholesterolemic and anticancer effects. Therefore, we aimed to investigate the role of dietary chitosan in reducing cadmium accumulation using an in vivo system. MATERIALS/METHODS: Cadmium was administered orally at 2 mg (three times per week) to three groups of Sprague-Dawley rats: control, low-dose, and high-dose (0, 3, and 5%, respectively) chitosan diet groups for eight weeks. Cadmium accumulation, as well as tissue functional and histological changes, was determined. RESULTS: Compared to the control group, rats fed the chitosan diet showed significantly lower levels of cadmium in blood and tissues including the kidneys, liver, and femur. Biochemical analysis of liver function including the determination of aspartate aminotransferase and total bilirubin levels showed that dietary chitosan reduced hepatic tissue damage caused by cadmium intoxication and prevented the associated bone disorder. CONCLUSIONS: These results suggest that dietary chitosan has the potential to reduce cadmium accumulation in the body as well as protect liver function and bone health against cadmium intoxication.

Graft-versus-host disease (GVHD), a life-threatening complication after bone marrow transplantation (BMT), is induced by activation of alloreactive donor T cells. Our previous study demonstrated that transplantation of myeloid differentiation factor 88 (MyD88)-deficient knockout (KO) bone marrow (BM) resulted in aggravation of GVHD. Here, to understand the cellular mechanism, we performed longitudinal in vivo imaging and flow cytometric analyses followed by transcriptome and functional examination of donor MyD88-KO BM progenies in GVHD hosts, using a major histocompatibility complex-matched but minor histocompatibility antigen-mismatched C57BL/6→BALB.B model. In GVHD hosts with MyD88-KO BMT, donor BM-derived CD11b+Gr-1+ cells were found to undergo cell death, a fate significantly different from the explosive expansion shown by the wild type (WT) counterparts, and also from the moderate expansion of the WT or MyD88-KO BM-derived cells in non-GVHD hosts. It was also revealed that MyD88-KO CD11b+Gr-1+ cells preferred differentiation into CD11c+ dendritic cells (DCs) to expansion as myeloid-derived suppressor cells in GVHD hosts or in high inflammatory in vitro conditions. These CD11c+ DCs comprised the majority of MyD88-KO CD11b+Gr-1+ apoptotic cells in GVHD hosts. Their ability to cross-present alloantigens of host origin contributed to the enhancement of T cell alloreactivity, causing GVHD aggravation and eventually death through the killing function of activated T cells. These results provide insights into the roles of MyD88 in myelopoiesis of donor BM and the protective effects in GVHD hosts, helpful information for development of a strategy to control GVHD.

The treatment outcomes with conventional second-line chemotherapy or radiotherapy aregenerally very poor for patients with relapsed primary CNS lymphoma (PCNSL). We treated three relapsed PCNSL patients with high-dose cytarabine plus etoposide (CYVE) chemotherapy, and this was followed by autologous stem cell transplantation (ASCT). The salvage CYVE chemotherapy consisted of cytarabine 2g/m2/d on days 2 to 5 in a 3-hour infusion and 50mg/m2/d on days 1 to 5 in a 12-hourinfusion, and etoposide 200mg/m2/d on days 2 to 5 in a 2-hour infusion. After two cycles of CYVE chemotherapy, two patients achieved a complete response (CR), and one patient achieved a partial response (PR). All three patients experienced febrile neutropenia and grade 4 thrombocytopenia with the CYVE chemotherapy. However, the hematologic toxicities were well managed without any complications. The conditioning regimen for ASCT consisted of BCNU 300mg/m2 on day -7, etoposide 100mg/m2 on days -6 to -3, cytarabine 100mg/m2 on days -6 to -3, and cyclophosphamide 35mg/kg on days -6 to -3 (BEAC). After ASCT, the patient who initially showed a PR with CYVE chemotherapy then achieved a CR. At the time of this report, one patient remained alive in CR for 41 months after CYVE chemotherapy. The remaining two patients experienced relapse 5 months and 4 months after ASCT, respectively, and they ultimately died of disease progression 18 months and 8 months after ASCT, respectively. In our cases, the CYVE chemotherapy+ASCT was well tolerated, and this induced the complete disappearance of the tumor, and one patient showed prolonged disease-free survival. CYVE chemotherapy+ASCT could be a treatment option for relapsed PCNSL.

PURPOSE: Bowel preparation with sodium phosphate was recently prohibited by the U.S. Food and Drug Administration. Polyethylene glycol (PEG) is safe and effective; however, it is difficult to drink. To identify an easy bowel preparation method for colonoscopy, we evaluated three different bowel preparation regimens regarding their efficacy and patient satisfaction. METHODS: In this randomized, comparative study, 892 patients who visited a secondary referral hospital for a colonoscopy between November 2012 and February 2013 were enrolled. Three regimens were evaluated: three packets of sodium picosulfate/magnesium citrate (PICO, group A), two packets of PICO with 1 L of PEG (PICO + PEG 1 L, group B), and two packets of PICO with 2 L of PEG (PICO + PEG 2 L, group C). A questionnaire survey regarding the patients' preference for the bowel preparation regimen and satisfaction was conducted before the colonoscopies. The quality of bowel cleansing was scored by the colonoscopists who used the Aronchick scoring scale and the Ottawa scale. RESULTS: The patients' satisfaction rate regarding the regimens were 72% in group A, 64% in group B, and 45.9% in group C. Nausea and abdominal bloating caused by the regimens were more frequent in group C than in group A or group B (P < 0.01). Group C showed the lowest preference rate compared to the other groups (P < 0.01). Group C showed better right colon cleansing efficacy than group A or group B. CONCLUSION: Group A exhibited a better result than group B or group C in patient satisfaction and preference. In the cleansing quality, no difference was noted between groups A and C.

PURPOSE: Home exposure to aeroallergens are an important environmental factor in allergic sensitization and in the development and exacerbation of asthma. Most studies of aeroallergens were dust mite in Korea, but cockroach distribution was little been known in Korea. The aim of this study was to evaluate species of cockroaches and seasonal distribution of cockroaches in Seoul area. METHODS: The study was performed during April 2000 through January 2001, from 63 houses in Korea. The total of 63 residential homes from different districts in Seoul were selected for the home environment survey. Bait traps (10 x 20 x 4 cm2, Zoro Zoro, Taisho Pharmacy, Tokyo, Japan) were placed on four different places of kitchen floor and one in the side of balcony in the house and left for 5 days to capture cockroaches. RESULTS: The cockroaches were captured in 23 houses(36.5%) out of 63 houses. And the inhabitant density of cockroaches was highest in the autumn(43.3%) followed by summer (29.2%), spring(18.3%) and winter(9.2%). In only 3 species were collected in Seoul area. The most common species were Blattella germanica showing 72.5% of the collected cockroaches, followed by Periplaneta japonica(25.2%) Periplaneta americana(2.3%). The total number of captured cockroaches was 504 and the number of nymph was 314(62.2%). Isolated house type showed higher trapping rates than the apartment. Positive skin test rates were 46.2% in the healthy control group and 43.8% in the allergy patients. CONCLUSION: Periplaneta americana was captured in Seoul area, which had not been found previously. The inhabitant density of cockroaches was the lowest in the winter.

PURPOSE: Allergens that cause asthma include those derived from indoor allergens such as animal dander (dog and cat). The aim of the study is to provide baseline data on characteristics of home environments in Korea, which will be used for future comparative studies of indoor environmental factors between populations with contrasting asthma prevalence. METHODS: The study was performed during September through November (Autumn) 1999. A total of 206 residential homes were volunteers from different districts in Seoul. They participate in home environment survey and skin prick tests. The dust specimens were collected by vacuum cleaner (V-582T, 520W; LG). We detected animal dander (Can f 1 and Fel d 1) by monoclonal-antibody based enzyme-linked immunosorbent assays (ELISA). RESULTS: The average indoor temperature was 25.1+/-2.9 degrees C and the relative humidity was 54.0+/-9.6%. The positive rate of dog (Can f 1) was 35.4% and cat (Fel d 1) was 33.5%. It is the same between Can f 1 and Fel d 1 distributed within dust samples from the four sites of the homes. And the distribution level of Can f 1 and Fel d 1 was, for the living room 26.2%, 17%, for the bedroom 20.9%, 15%, for the children's room 20.4%, 10.2%, for the kitchen 16%, 8.7 %, in descending order. CONCLUSION: The positive rate of Can f 1 was higher than Fel d 1 in dust samples. The living room has highest distribution of dust samples among the four sites of a home. And it has similar distribution between Can f 1 and Fel d 1.

BACKGROUND/AIMS: Helicobacter pylori infection is a recognized cause of chronic gastritis, peptic ulcer and gastric adenocarcinoma. However, both positive and negative associations with colorectal neoplasia have been reported. The aim of this study was to determine whether H. pylori infection is associated with an increased risk of colonic neoplasia in a Korean population. METHODS: We examined 1,590 subjects (1,297 men and 293 women) who underwent colonoscopy and serologic testing for IgG antibodies against H. pylori at the Health promotion Center in Kangbuk Samsung Hospital and at Samsung Medical Center. We compared the prevalence of colonic neoplasia in the seropositive subjects with that of the seronegative subjects. RESULTS: The overall prevalence of H. pylori in our study population was 56.2%. There were no significant differences of the baseline characteristics between the two groups. There was no statistically significant difference in the prevalence of colonic neoplasia between the seropositive group and the seronegative group (p=0.090). CONCLUSIONS: These findings suggest that there is no significant association between H. pylori infection and colonic neoplasia.
