PURPOSE: To evaluate clinical and radiological results and to analyse the parapatellar complications after endoscopic anterior cruciate ligament reconstruction using central one-third bone-patellar tendon-bone autografts. MATERIALS AND METHODS: 66 cases among 158 consecutive cases from Feb 1990 to May 1996 were reviewed and evaluated with regard to patellofemoral pain, crepitus, quadriceps atrophy, graft donor site complication, Lysholm knee scoring system and radiological assessment. The average period of follow up was 23 months (range, 12-57 months) and the average age at operation was 31 years old (range, 18-58 years). RESULTS: The average Lysholmn knee score improved from 57.5 points preoperatively to 91.3 points at follow up. The instrumented anterior laxity test showed that excellent anterior stability was regained in most patients. There were many cases of parapatellar complications, 7 cases (10.6%) of anterior knee pain, 21 cases (32.8%) of crepitus, 43 cases (65.1%) of quadriceps weakness, 29 cases (45.3%) of graft donor site paresthesia and 15 cases (23.4%) of pain on kneeling. CONCLUSIONS: Although endoscopic ACL reconstruction using central one-third bone-patellar tendon-bone autografts had good clinical results, many parapatellar complications were noted. In order to prevent these complications, different reconstruction techniques and graft materials should be considered

BACKGROUND: Cerebral white matter lesions(WMLs), such as leukoaraiosis, may be related to damage from cerebral ischemia and may also be associated with the degenerative process. The apolipoprotein E (APOE) 4 allele is a risk factor for degenerative diseases, such as Alzheimer`s disease, and ischemic brain damage through acceleration of atherosclerosis. No study has been performed regarding WMLs and APOE genotype in Korea. We investigated the association between WMLs and APOE among Koreans. METHODS: Brain MRI was performed in 225 subjects(ages 61 to 85 years) without neuropsychiatric disease randomly selected from the Ansan Health Cohort Study. WMLs observed on 225 MRI scans were rated in terms of severity by 2 raters. All study subjects underwent APOE genotyping. RESULTS: WMLs were observed in 109(48.4%) of subjects. In the subjects with WMLs, the distribution of APOE genotypes was 0.9% for epsilon 2/epsilon 2, 11.0% for epsilon2/epsilon3, 1.8% for epsilon2/epsilon4, 61.5% for epsilon3/epsilon3, 22.9% for epsilon3/epsilon4, and 1.8% for epsilon4/epsilon4, respectively. The distribution of APOE genotypes did not differ between subjects with and without WMLs. CONCLUSION: These data suggest that there is no association between WMLs and APOE genotypes in Koreans.

PURPOSE: This study was done to explore communication between nurses during preceptorship. METHODS: A qualitative study, using content analysis was conducted. Semistructured interviews were held with 10 nurses working in urban hospitals. RESULTS: A total of 226 significant statements were selected from the data and classified into 4 categories and 23 subcategories. Communication experiences of new nurses' own performance were responses to reproach - acceptance and apology, and unresponsiveness due to feeling small and uncomfortable; responses to questions - misanswer; responses to directions - unconditional acceptance. Communication experiences of new nurses' performance by nurse preceptors were kindness, stigmatization, talking behind one's back, criticism and reproach, impolite words, and emotional expression. Communication experiences of nurse preceptors's own performance were directives, sympathy, reproach, unkindness, authoritative strictness, and nonverbal expression: being cold, and lessening of tension. Communication experiences of nurse preceptors' performance by new nurses were response to criticism - recognition and apology for mistakes, evasion of responsibility, and excuses; responses to explanations-active acceptance, and difficulty with communication due to lack of comprehension. CONCLUSION: These results provide deep understanding of nurses' communication during preceptorship and should help in developing comprehensive education programs for preceptor nurses and new nurses.

We present a patient with high 18F-fluorodeoxyglucose (FDG) uptake detected in a neurofibroma that was confused with sarcomatous transformation on a positron emission tomography/computed tomography (PET/CT) scan. A 39-year-old male patient with a 20-year history of neurofibromatosis-1 (NF-1) performed FDG PET/CT scan for the evaluation of lesions with sarcomatous transformation. The FDG PET/CT images demonstrated varying degrees of increased FDG uptake in the multiple nodules throughout whole body. The left pelvic mass with the highest FDG uptake had a maximum standardized uptake values (maxSUV) 5.0 and surgical resection was performed. Histological analysis confirmed the presence of a benign neurofibroma infiltrated with inflammatory cells.

PURPOSE: To evaluate effect of modified arthroscopic pull-out suture technique which used number 5-nonabsorbable suture material for tibia intercondylar eminence comminuted fractures. MATERIALS AND METHODS: There were 21 cases of tibia intercondylar emimence fracture which arthroscopic treated at our hospital between 1999 and 2004. However the study population only included 12 cases in which a number 5-nonabsorbable suture material (Ethibond No. 5) was used for tibia intercondylar eminence comminuted fractures and minimum 1-year follow-up has gone. The average follow-up period was 18.5 months (range, 12 to 42 months). Lachman test and KT-2000 athrometer test were evaluated at the pre-and post-operation. Clinical results of all patients were evaluated with the Meyers and Mckeever 's criteria. RESULTS: In all 12 cases, the normal range of motion and sports activities were recovered at the final follow-up. When tested for anterior instability with KT-2000 arthrometer, there were no different between normal knee and operated knee. Clinical results by Meyers and Mckeever's criteria were excellent in 10 patients and good in 2 patients. CONCLUSION: We obtained early mobilization and stable fixation in modified arthroscopic pullout suture technique for tibia intercondylar eminence comminuted fractures. Patients can early return to his job. This technique seems to be one of the effective operative techniques for treatment of tibia intercondylar eminence comminuted fractures.

PURPOSE: After the RS (respiratory syncytial) virus, the influenza virus is the most common cause of childhood lower respiratory tract infection. We assessed the radiologic findings of childhood lower respiratory tract infection by the influenza virus. MATERIALS AND METHODS: A total of 105 pediatric patients (76 males and 29 females; mean age, 2.4 years) with symptoms of respiratory tract infection were examined between March 1997 and April 2000. Nasopharyngeal aspirates were obtained and influenza virus infection was confirmed by direct or indirect immunofluorescent assays. Peribronchial infiltration, hyperinflation, atelectasis, pulmonary consolidation, and hilar lymphadenopathy were evaluated retrospectively at simple chest radiography. RESULTS: Bilateral perihilar peribronchial infiltration was noted in 78.1% of patients (n=82), hyperinflation in 63.8% (n=67), atelectasis in 3.8% (n=4; segmental 50%, lobar 50%), and pulmonary consolidation in 16.2% [n=17; segmental 70.6% (n=12), lobar 29.4% (n=5)]. Hilar lymphadenopathy was noted in one patient in whom there was no pleural effusion, and subglottic airway narrowing in 12 of 14 in whom the croup symptom complex was present. CONCLUSION: The major radiologic findings of influenza virus infection were bilateral perihilar peribronchial infiltration and hyperinflation. In some patients, upper respiratory tract infection was combined with subgolttic airway narrowing. Atelectasis or pleural effusion was rare.

Objective: In the early short-term therapy of pulmonary tuberculosis, PZA is used for the first two months on 6EHRZ therapy but PZA is not effective in the case of long-term use PZA for retreatment in the sensitive relapse or acquired drug resistance for PZA. But in the endemic area as Korea, if we can't use PZA in the retreatment of pulmonary tuberculosis, we can't expect the success for retreatment of pulmonary tuberculosis, therefore we need new drugs substituting for PZA. In these days, 4-fluoroquinolone derivatives were investigated and only ofloxacin and ciprofloxacin of derivatives were known to be effective but the effectiveness was also not certain because the result was experimental or combined with other bacteriocidal drugs and datas on effectiveness of pulmonary tuberculosis were so little. Therefore these drugs should be use with other two or three strong-acting drugs in the last period of retreatment of pulmonary tuberculosis. The ofloxacin or ciprofloxacin is used in some area in Korea but randomly and needed more study. We did this study for proving the effectiveness of these drugs and establishment of retreatment regimen for pulmonary tuberculosis. Methods: Retrospective cohort study of 83 drug-resistant pulmonary tuberculosis patients at National Masan Tuberculosis Hospital from Jan. 1994 to dec. 1995 was made. All the patients taken medicine for 2nd anti-tuberculosis regimens for the first time. We separated the patients by two groups.(Group I: OFX+PTA+CS+PAS + Injection, Group II: PZA+PTA+CS+PAS+Injection). We compared the difference between two groups and tested the confidence limit about results after treatment by chi2-test and T-test. Results: 1. The age distribution was most frequent in fourth decade(29.2% in Group I, 37.1% in Group II) and the mean age was 43.9 year in Group I, and 39.0 year in Group II, but had no significant difference between two groups. The sex distribution was more frequent in the males(68.8% in Group I, 85.7% in Group II), but had no significant difference. 2. Family history was 29.2% in Group I, 28.6% in Group II, but had no significant difference. 3. In the respect of extent of disease, far-advanced state was 60.4% in Group I, 74.3% in Group II, but had no significant difference. 4. The side effects for drugs showed in 58.3% in Group I and 65.7% in Group II, and the gastrointestinal trouble showed 25.0% in Group I and arthralgia 34.3% in Group II predominantly respectively and had the significant difference(p<0.05). 5. The negative conversion rate on sputum AFB smear was 87.5% in Group I and 80.0% in Group II, but had no significant difference. But the negative conversion rate on sputum AFB culture was 83.3% in Group I and 57.1% in Group II and had the significant difference(p<0.05). 6. The success rate of treatment was 87.5% in Group I and 83.3% in Group II but had no significant difference. Conclusion: In the retreatment of pulmonary tuberculosis, ofloxacin is useful drug for the patients who are not available to use PZA and can be use effectively substituting for PZA.

Erysipelothrix rhusiopathiae is an uncommon pathogen in human, which causes zoonotic infection. The most common type of human disease with E. rhusiopathiae is a localized skin infection (erysipeloed). E. rhusiopathiae endocarditis is very rare, which usually develops in normal heart valves and causes a variety of complications leading to valve replacement. We described a case of E. rhusiopathiae endocarditis which developed in a 56-year-old man without a predisposing valvular heart disease. In this case, aortic valve and mitral valve were involved and emergency valve replacement was required, which improved patient's condition markedly. Intravenous therapy with penicillin G and subsequent ceftriaxone were given for 8 weeks after surgery and he was recovered without relapse.

Bacillus anthracis, the etiological agent of anthrax, has been taxonomically classified into Bacillus subgroup I with B. cereus, B. mycoides, and B. thuringiensis based on their phenetic and genetic charateristics. Especially, DNA studies indicated that these species were closely related hence these species has been proposed as a single species with four subspecies. There has been controversy about taxonomy of B. anthracis isolates because none of the simple and rapid identification methods are available for closely related taxa so far. In this study, we have used VNTR analysis for reidentification of 7 strains of B. anthracis and 9 strains of closely related species. In the PCR analysis, All of the B. anthracis had a variable region of DNA sequence exception with Youngdungpo. One polymorphisms were found by the presence of four copies with the 12-bp tandem repeat sequences except Kunja. Of the closely related species, the equal size of (VNTR)' was amplified from Bacillus spp. Kyungjoo 3 and B. cereus. The sequences of Kyungjoo 3 was identical with B. anthracis. Whereas the tandem repeat sequences was not found in B. anthracis Kunja and B. cereus. Therefore, B. anthracis Kunja was finally reidentified as a B. cereus. As a results, the analysis of VNTR could be used for rapid identification for B. anthraicis from B. anthracis closely related taxa and molecular epidemiological studies of anthrax.
