PURPOSE: To evaluate the diagnostic capabilities of the low-field (0.2T) magnetic resonance (MR) system in the detection of the superior labrum anterior to posterior (SLAP) lesion. MATERIALS AND METHODS: One hundred fifty patients underwent magnetic resonance imaging of the shoulder over a 7-month period. Forty-six patients underwent arthroscopic surgery, and the surgical results were correlated with the findings of the MR imaging. Arthroscopic procedures were performed within a mean of 8 days after MR imaging. MR imaging of the shoulder was conducted as follows: shoulder coil; T1-weighted spin echo, coronal-oblique images; T2-weighted gradient echo, coronal-oblique and axial images; and T2-weighted spin echo, coronal-oblique and sagittal-oblique images. Prospectively, one radiologist interpreted the MR images. RESULTS: The results of surgery were as follows: SLAP II in 26 shoulders, SLAP III in 1 shoulder, SLAP IV in 1 shoulder, normal labrum in 6 shoulders. For SLAP lesions with a higher grade than type 2, the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the low-field MRI were 85.7%, 55.5%, 75%, 71%, and 74%, respectively. CONCLUSION: There was relatively good agreement for the comparison of the MR results obtained using a low-field MR system with the surgical findings for identifying SLAP lesions.

The most feared complication of left ventricular thrombus (LVT) is the occurrence of systemic thromboembolic events, especially in the brain. Herein, we report a patient with severe sepsis who suffered recurrent devastating embolic stroke. Transthoracic echocardiography revealed apical ballooning of the left ventricle with a huge LVT, which had not been observed in chest computed tomography before the stroke. This case emphasizes the importance of serial cardiac evaluation in patients with stroke and severe medical illness.

Fibronectin(FN), a glycoprotein present in plasma and extracellular matrix, has been reported to be effective on various corneal disorders such as persistent epithelial defect, corneal trophic ulcer, herpetic keratitis, etc. We performed the study of the preparation of purified FN from 35 persons' plasma(male: 19, female: 16)by the use of Sepharose 48 Affinity Chromatography and Gel filtration. The prepared FN was pure electrophoretically, and no other plasma proteins were contaminated, and confirmed as pure by multiple methods such as SDS-P AGE, Ouchterlony double gel diffusion and immunoelectro phoresis. Only 40 minutes was taken for preparation. The result showed that FN concentrations in plasma and in prepared solution were 288.9 +/- 72.8 microgram/ml and 294.3 +/- 41.4 microgram/ml respectively. FN concentrations in plasma and FN eyedrops showed no difference between sex, but increased their level with age(p<0.05). The biological activity was better preserved at 4 degrees C(in the refrigerator) than at room temperature till about 4 weeks after preparation. Applicability of this method as a useful preparation of purified FN is recommendable.

An epidemiologic investigation was carried out to identify the source of infection of typhoid fever outbreak, which was occurred in Nam-Gu, Pusan city from April 20 to June 28, 1996. The distribution of 83 reported cases (55 confirmed cases and 28 suspected cases) by sex and age group showed that this epidemic would be occurred by the exposure to a common source with low toxic pathogen because 55.4% of cases were under 20 years old and most of the adults cases were female. The epidemic curve showed a unimodel curve with a peak on about 15 May and tailed down to 23 June, suggesting that the exposure was constant. These results supposed that the contamination of a public water supply would be the source of infection. The analysis of reported cases and population survey conducted to household members and community contacts living in the epidemic area, led the conclusion that the source of infection was tap water supplied through the Dae Youn pumping station, based on the following findings: (1) There were singificant differences of incidence rate among regions (Tong) even though in the same Dong and the spot map of incident cases distributed in accord with the water supply by Dae-Youn pumping station. (2) Among reported cases, 21 cases, including 17 confirmed cases, stated they had used only tap water. (3) The analysis of tap water from the house which had seven typhoid cases, revealed the contamination of E coli and the dilution of residual chlorinated concentration. (4) The outbreak of typhoid fever was stopped after the replacement of The worn-out pipe line of tap water supply to the new one.

Hantaan viruses cause haemorrhagic fever with renal syndrome (HFRS), resulting in severe morbidity and mortality in humans. The genome of Hantaan virus is composed of three segmented and single stranded negative sense RNA genome. In this study, we expressed nucleocapsid (N) proteins of Hantaan 76-118, Seoul 80-39 and Hantaan virus isolated in Korea (01-23) using E. coli system. These N proteins were fused with a thioredoxin protein for secretion of the expressed protein. The antigenicity of each expressed N proteins was examined in Western blot with sera from HFRS patients and normal controls. The expressed N proteins did not show any cross-reactivity with sera obtained from patients with leptospirosis and tsutsugamushi disease. These results suggest that our recombinant N proteins can be used for the development of diagnostic system to distinguish between HFRS and leptospirosis or tsutsugamushi.

PURPOSE: Due to its high potency against leukemic blasts, our institution has opted for the use of dexamethasone during acute lymphoblastic leukemia (ALL) remission induction, but in our most recent treatment protocol, CMCPL-2005, we shortened the length of steroid treatment from 4 to 3 weeks. We compared both the rates of remission induction and significant complications observed during induction with CMCPL-2005, with those noted for our previous protocol, CMCPL-2001. METHODS: We retrospectively reviewed the records of patients diagnosed with ALL from January, 2001 to December, 2006 at the Department of Pediatrics, St. Mary's Hospital, the Catholic University of Korea. Data concerning age, sex, WBC count at diagnosis, immunophenotype, cytogenetic traits, and risk group were collected for each patient. Results of remission induction treatment were compared between the two patient groups. Infection and other major complications resulting from treatment were investigated according to NCI toxicity criteria. RESULTS: A total of 141 and 88 patients received remission induction under CMCPL-2001 and CMCPL-2005 respectively. In the CMCPL-2001 group, 136 (96%) achieved complete remission while 82 (93%) achieved CR in the CMCPL-2005 group. Patients in the CMCPL-2005 group were more likely to undergo remission induction without experiencing major complications. However, with regards to steroid related toxicities such as infection, no significant differences were noted. CONCLUSION: We shortened the length of steroid administration from four to three weeks, yet found the remission induction rate to be comparable to that of our previous regimen. However, rates of steroid related toxicities such as infectious complications remain unchanged despite shortened exposure to dexamethasone.

PURPOSE: In this study, we retrospectively analyzed the clinical outcomes of patients who underwent allogeneic hematopoietic stem cell transplantation (HSCT) grafted from HLA-matched parents. METHODS: Seven children with acute leukemia (4 acute lymphoblastic leukemia, 3 acute myeloid leukemia) in first complete remission received allogeneic HSCT from their respective parents at the St. Marys Hospital between April, 1999 and October, 2005. The median age of patients at transplantation was 5 years (range, 1-11 years; 2 male, 5 female) and the median age of donors was 35 years (range, 30-41 years; 5 male, 2 female). We investigated the clinical outcomes such as engraftment, acute and chronic graft-versus-host disease (GVHD), transplant-related morbidity and mortality, relapse and survival. RESULTS: Median time from transplantation to last follow-up was 69.5 months (range, 18.8-96.5 months). All patients were successfully engrafted, with a median time of 11 days (range, 10-16 days) and 26 days (range, 13-39 days) for neutrophil and platelet recovery, respectively. Grade II acute GVHD occurred in 3, and grade III acute GVHD in 1 of 7 recipients. Extensive chronic GVHD developed in 2, and limited chronic GVHD in 1 of 7 recipients. Death from transplant-related complications occurred in 1, and relapse occurred in 1 of 7 recipients. Estimated 5-year overall survival was 83+/-15%. CONCLUSION: The clinical outcomes of recipients who underwent HSCT from HLA-matched parents were comparable to those of patients who received HSCT grafted from HLA-matched sibling donors in childhood leukemia. HLA typing of parents, as well as siblings will increase the likelihood of finding an HLA-matched family donor for patients who need HSCT.

BACKGROUND: Investigating the blood usage and blood wastage in Korea hospitals national wide, and including all types of medical institutes, has not been sufficient with the only study having been carried out by the KCDC thorough an Academic Research Contract in 2007. Yet that study was limited due to lack of participation from hospitals. Our study tried to establish a fundamental database for blood transfusion management by investigating the current status of blood products usage, under the KCDC's supervision, to improve participation from medical institutes. METHODS: From January to December in 2008, the Blood Bank, Red Cross of the Republic of Korea looked into the blood product supply of all the medical institutes and we conducted a national survey using questionnaires distributed via the local public health centers on the blood use, blood waste, the reasons for waste and the inventory of the remaining blood. The supply, as compared to the actual use of blood products in the same period, was analyzed by the Korean Red Cross. RESULTS: The total amount of blood products distributed by the Korean Red Cross to medical institutes in 2008 increased by 13.8% for platelets, 11.5% for RBC products, 8.4% for apheresis products and 2% for FFPs, as compared with that of 2006. A total of 2,500 institutions participated in the questionnaire and 60.7% (1,517 out of 2,500 institutes) of the institutes sent feed-back. The total amount of blood use was 3,483,636 units and 52% of the consumption was focused in metropolitan areas like Seoul, Geong-Ki and Busan. The total wastage rate for blood was 1.2% and it was 4.8% for institutes with admitting capacities of 100 beds or less, with expiration of the storage date being the main reason for wastage, while the wastage rate was 1.1% for general hospitals with admitting capacities of 500 beds or more, with an improving patient status or death being the main reason. CONCLUSION: The results of this study were similar to those of 2007, but the participation rate from medical institutes was much increased. Establishment of an investigational system for the use of blood products in medical institutes on a national level is needed to secure data for dealing with the increased projected demand of blood/blood products in the future.
