In the orthopedic Department of Jeonbug National University Hospital, twenty-five open tibial shaft fractures were reviewed and analyzed with osteomedullography and bone scanning with radioactive isotopes from June 1981 to October 1983. The results are as follows. 1. The cases of injury were mostly traffic accident(70.8%) and majority was found between second decade and third decade. Males were 11 times more frequent than females. 2. In the shape and location of fractures, comminuted fracture(60%) was most common, and fracture of middle one third(48%), lower one third(28%) were in order. 3. In the open tibial fractures, Grade I. of soft tissue injury was most frequent(64%). As inthe plate fixation was required, we should it placed atypically on the posterior surface of the tibia. 4. In the osteomedullography at 3 months after treatment, the rate of positive finding was 80 and intraosseous crossing vein(Kaski sign 1) was observed most frequently. 5. In the profile of the bone scanning with radioactive isotopes, the rate of single-peak uptake was 76% and twin-peak uptake was 24%. 6. In the negative Osteomedullogram and twin-peak uptake on the profile of the bone scanning, bone graft was necessary. 7. In the case of difficult diagnosis for union process of tibia fracture, osteomedullography and bone scanning with radioactive isotopes were considered useful method of early diagnosis.

BACKGROUND: This study was purposed to establish reference values for platelet activation markers and leukocyte-platelet aggregates in the evaluation of the platelet function tests using flow cytometry. METHODS: Whole blood samples were obtained from 30 volunteers of healthy adults. Diluted blood samples, either in the resting state or in activated state by the addition of agonist, 20 micrometer ADP or 100 micrometer TRAP, were stained with fluorescent conjugated monoclonal antibody of PAC1 or CD62P. Then, the percentages of expression for each marker were analyzed by flow cytometry. For leukocyte-platelet aggregates, monoclonal antibodies of CD41a, CD14 and CD45 were added simultaneously to undiluted whole blood. RESULTS: Reference values for the percentages of the expression of PAC1 and CD62P, respectively, were 0.1-12.5% and 0.0-4.7% at the resting state, 65.3-92.4% and 39.0-75.7% with the addition of 20 micrometer ADP, and 68.1-93.1% and 60.5-91.2% with the addition of 100 micrometer TRAP. Reference values for leukocyte-platelet aggregates, granulocyte-platelet aggregates, and lymphocyte-platelets aggregates were 2.8-23.6%, 5.3-34.2%, and 4.9-21.6%, respectively. CONCLUSIONS: The platelet activation markers at the resting or an activated state with agonists and leukocyte-platelet aggregates could be analyzed using flow cytometry. These reference values should be helpful in interpreting platelet function tests by flow cytometry.

Early recognition of coalescence in pneumoconiotic lesions is important because such coalescence is associated with the respiratory symptoms and deterioration of lung function. This complicated form of pneumoconiosis also has worse prognosis than does simple pneumoconiosis. High resolution computerized tomography(HRCT) provides significant additional information on the stage of the pneumoconiosis because it easily detects coalescence of nodules and emphysema that may not be apparent on the simple radiograph. The Purpose of this study is to clarify the role of HRCT in detection of large opacity and the relationship of change between the coalescence of nodules or emphysema and lung function in dust exposed workers. 1. There was good correlation between the HRCT grade of pneumoconiosis and ILO category of profusion. 5(9.09%) in 55 study population had confluent nodule extending over two or more cuts on HRCT. HRCT could identify the pneumoconiotic nodules which was not found by simple radiography in 6 workers with category 0/0. 2. No significant difference was observed coalescence of nodules and emphysema by dust type. 3. There was no significant difference in pulmonary function according to ILO and HRCT classification. 4. HRCT could detect the significant reduction in FEV1, FEV1/FVC, PEER, FEF25, FEF50, and FEF75 and remarkable increase in RV and TLC in study persons with emphysema compared with non-emphysema group. 5. Emphysema was found more often in nodules-coalescence group than small opacity group by HRCT. We found that HRCT could easily detect areas of coalescence and complicated emphysema compared to plain chest X-ray. Also our data suggest that it is primarily the degree of emphysema rather than the degree of pneumoconiosis that determines the level of pulmonary function.

High tibial osteotomy is a useful procedure in the treatment of early stage osteoarthritis of the knee which is confined to the medial compartment. But long term follow-up study of high tibial osteotomy has not been provided yet and its prerequisite for a successful result still remains unrevealed. Since the osteoarthritis can progress after the osteotomy, it may result in the loss of correction and recurrence of pain and require conversion to total knee replacement arthroplasty. We studied clinically and radiologically the long term result of high tibial osteotomy in 11 patients(16 knees) who had been treated at the Department of Orthopaedic surgery of Seoul Paik Hospital during the period from January, 1978 to May, 1989, and follow-up for longer than 4 years. Preoperative mean varus angle was 6.4 degrees and immediate postoperative mean valgus angle was 8.6 degrees and final mean valgus angle was 4.7 degrees. The average loss of correction angle was 3.9 degrees. At 2-year follow-up, the results of 16 knees were as follows; excellent in six knees, good in seven knees. The final results at average 7.2-year follow-up were excellent in four knees, good in six knees and one knee was converted to total knee replacement arthroplasty. The results showed deterioration of clinical results and loss of correction with time after osteotomy. However, in more than half of the cases the results were good or excellent at the final follow-up, We, therefore, conclude that high tibial osteotomy is still a useful procedure in osteoarthritis of the knee if performed with a precise surgical technique and an adequate overcorrection more than 10 degrees.

Purpose: This study was conducted to understand the meaning of the work performance of infection control nurses (ICNs) in general hospitals during the early COVID-19 pandemic. Methods: This was a qualitative study to explore and describe the implications of the work performance of ICNs during the early COVID-19 pandemic through a phenomenological approach. One-on-one in-depth interviews were conducted with ICNs who had been working since before the COVID-19 pandemic in the infection control department. Results: The topics brought up by the participants were categorized into five themes. The themes included “confusion caused by the early COVID-19 pandemic,” “exhaustion due to an explosion of work related to COVID-19,” “active response as an ICN,” “emphasis on the importance of infection control,” and “overcoming the early COVID-19 pandemic”. Conclusion It is necessary to strengthen the competence of ICNs as experts and establish a career management system to overcome the confusion and physical and psychological difficulties experienced by ICNs.

PURPOSE: We investigated the risk factors related to the development and aggravation of allergic rhinitis, which is associated with residential environment and lifestyle habits of children residing in Incheon. METHODS: A total of 182 children diagnosed with moderate to severe allergic rhinitis and 67 healthy children were enrolled. A detailed questionnaire of the environmental characteristics and the dietary habits were completed by the parents. Further, skin prick tests with 14 common allergens were performed. RESULTS: The mean age of the children with allergic rhinitis and healthy control was 8.2+/-2.8 and 9.4+/-2.0 years, respectively. The presence of indoor mold was associated with an increased risk of development of allergic rhinitis. (adjusted odds ratio [aOR], 4.26; 95% confidence interval [CI], 1.96-9.27) Among the food groups, there was no significant difference of the daily intake of milk and yogurt between the patients and the controls. However, daily intake of vegetables, except Kimchi, and daily intake of fruits or fruit juice were associated with a decreased risk of allergic rhinitis. (aOR, 0.43; 95% CI, 0.20-0.92 / aOR, 0.43; 95% CI, 0.13-0.90, respectively) CONCLUSION: The results indicate that an indoor dampness is one of the risk factors of development and aggravation of allergic rhinitis. Control of indoor humidity and daily intake of fruits and vegetables can prevent the development and control symptoms of allergic rhinitis.

Osteochondromas are common and typically arise from the metaphyseal ends of long bones. An osteochondral neoplasm of the soft tissue, which is a lesion of uncertain pathogenesis, is uncommon and usually arises from the synovial tissue in joints and tendon sheaths. Rarely, extraskeletal osteochondromas also arise outside of synovial compartments. Most of the reported cases were presented in the hands and feet, especially in the fingers. Here we describe a 44-yr-old female patient who presented with a pain in the left buttock. A well-defined osseous mass was detected in the buttock. It consisted of sharply demarcated, mature hyaline cartilage that was covered with a fibrous capsule, which changed gradually into cancellous bone, more pronouncedly at the center. The diagnosis of an extraskeletal osteochondroma should be considered when a discrete, ossified mass is localized in the soft tissues. A case of pathologically proven extraskeletal osteochondroma of the buttock is presented with a literature review, magnetic resonance imaging, and radiological findings.

BACKGROUND: Patients with a prior myocardial infarction who undergo noncardiac surgery have a higher risk of perioperative morbidity and mortality. Therefore, this study was designed to assess the outcomes after non-cardiac surgery in patients who had a previous myocardial infarction. METHODS: Ninety three patients who had a prior myocardial infarction and underwent noncardiac surgery were included in this study. The patients were divided as follows: the Complication group versus the Non-Complication group. A retrospective analysis was performed to determine if age, gender, ejection fraction, prior coronary revascularization, ASA physical status, operation time and type, perioperative vital signs, cardiac risk factor, preoperative medications and coronary multivessel disease influence the perioperative morbidity and mortality. RESULTS: Fourteen of the 93 patients (15.1%) had perioperative complications, of which 3 (3.2%) were fatal. All fatal patients had undergone noncardiac surgery within 3 months after the previous coronary revascularization. The incidence of intraoperative tachycardia and oliguria, operation time and the ASA physical status were longer and greater in the Complication group (P<0.05). Otherwise there were no significant differences between the two groups. CONCLUSIONS: The incidence of intraoperative tachycardia and oliguria, the operation time and ASA physical status influence the outcomes after noncardiac surgery of patients with a prior myocardial infarction. In addition, the interval between the coronary revascularization procedure and the noncardiac surgery has a major impact on postoperative mortality. However, prospective multi-center studies will be needed to determine the effects of several variables.
