Purpose: To determine the usefulness of limb salvage operation with recycled autogenous bone graft in musculoskeletal malignant tumors. Materials and Methods: Twenty nine cases, who underwent limb salvage operation with recycled autogenous bone graft for the treatment of musculoskeletal malignant tumor between February 1990 and January 2003, were included. There were 18 males and 11 females and the mean age was 33 years (range, 10 to 65 years). The mean follow-up period was 51.8 months (range, 18 to 117 months). The Enneking stage was IIA in 10 cases and IIB in 19 cases. The recycling method of autogenous bone was deep freezing in 6 cases, autoclaving in 11 cases, pasteurization in 7 cases and the composite of autoclaving and vascularized fibular graft in 5 cases. The union of junctional site was evaluated radiologically and the functional results was analyzed by the grading systems of the International Symposium On Limb Salvages (ISOLS). Results: The mean union time was 7.2 months (range, 3 to 15 months). The union took 5.8 months (range, 4 to 8 months) in deep freezing, 9.7 months (range, 6 to 15 months) in autoclaving, 5.9 months (range, 4 to 8 months) in pasteurization, and 5 months (range, 4 to 8 months) in the composite of autoclaving and vascularized fibular graft. The mean functional evaluation percentage was 76.8% (range, 40 to 90%). It was 65.8% (range, 40 to 85%) in deep freezing, 76.6% (range, 40 to 90%) in autoclaving, 81.6% (range, 70 to 90%) in pasteurization, and 83.4% (range, 75 to 90%) in the composite of autoclaving and vascularized fibular graft. There were 6 cases of complications including 1 case of local recurrence, lung metastasis, infection, fracture, respectively and 2 cases of nonunion. Conclusion: The limb salvage operation with recycled autogenous bone graft is a useful treatment method for the musculoskeletal malignant tumors. Particularly, autoclaving is the most reliable sterilization method. The vascularized fibular graft can compensate decreased osteoinductivity and mechanical strength of recycled bone. So, the composite of autoclaving and vascularized bone graft seems to be a favorable treatment method for high grade malignant musculoskeletal tumors.
Backround : Pneumoconiosis is the parenchymal lung disease that results from the inhalation and deposition of dust, usually mineral dust of occupational or environmental origin. Most of the pneumoconiosis can be categorized to coal workers' pneumoconiosis (CWP) in Korea. No effective treatement is currently available, and the therapy for symptomatic CWP is limited to treatment of complication. Therefore authors analyzed and reviewed clinical features and radiological findings of 95 patients with pneumoconiosis for assessing the prognostic factors in disease progression. Method: We reviewed medical records of 95 cases with pneumoconiosis including history, chest X-ray, pulmonary function test, electrocardiography, AFB stain and culture of sputum, and routine blood examination between June 1995 and June 1997 in Seonam University Namkwang Hospital. Results: All of cases are male(mean age, 57.4 years), 91 cases out of them are miners. The mean duration of exposure to dust is 18.8 years. Major clinical symptoms are dyspnea (100%), sputum (71.6%), chest pain (55.8%), cough (23.2%), and hemoptysis (6.3%). 82 % of cases are over Morgan-Seaton Grade 2 in the degree of dyspnea. Small opacity on chest x-ray is 82.1 % and large opacity is 17.9%. Small opacity has tit type (37.2%), q/q type (25.6%) and r/r type (11.5%). B type is 42.2% in large opacity. For the pulmonary function test, restrictive type is 40.3%, mixed type 19.5% and obstructive type 8.3%. The more increasing chest Xray density, the more decreasing $FEV_1$ (p<0.01). 38% of patients show tuberculosis in chest X-ray, 15.8% positive smear of acid fast bacilli in sputum. The prevalence of pulmonary tuberculosis is high in patients with poor clinical condition. The cases with the active pulmonary tuberculosis have severe dyspnea. Expired cases show 100% and 75% of positive pulmonary tuberculosis in chest X-ray and sputum examination, respectively. 75% of expired cases show the chronic cor pulmonale, who died of acute respiratory failure. Conclusion: These findings indicate that tuberculoois infection has a decisive influence on the progress and prognoois of pneumoconioois.
Background: Pulmonary paragonimiasis is caused by consumption of raw or improperly cooked crabs infected by a laval stage (metacercaris) of the parasite. In our country it had been a highly prevalent endemic disease until th late 1960s, and after then it's prevalence has been markedly decreased. But because some people have continued to ingest undercooked crabs, this disease have yet occured sporadically. Methods: We reviewed the clinical and radiological findings retrospectively in seventy-four patients of pulmonary paragonimiasis including familial infestation in 7 familes (20 cases) who were confirmed by food history, clinical and radiological findings, and labaratory data. Results: The male: female ratio was 2.2:1 and most prevalent age was 40-49 years old. Twen6ty nine patients (39%) had ova-positive infection. The detection sites were sputum (48%), pleural fluid (17%), fine needle aspiration biopsy of nodular or cystic lesion (17%), pleural biopsy (7%), skin nodule biopsy (7%), and stool (3%). The patients had pulmonary symptoms in 63 cases (85%) but 9 cases did not have any symptoms. The 53 cases (72%) had abnormal radiological findings in lung parenchyme (75%) and pleura (63%). However 21 cases (28%) showed no specific findings in their chest X-ray. Serum titers (ELISA) of specific IgG for paragonimiasis in 13 cases were followed for average 9.8 months after treatment, which showed slow decreasement. In the evaluation of family member (7 family, 20 cases), all members having the common dietary history together with a proven patients were confirmed this disease by serological test, regardless of the presence or the abscence of clinical or radilogical symptoms. Conclusion: We evaluated the clinical and radiological findings in 74 cases of pulmonary paragonimiasis including 7 family members who had a history of ingestion of improperly cooked crabs together with patients. The paients of pulmonary paragonimiasis have various findings in clinical and radiological findings. Common diet exposure history and laboratory findings including specific IgG were important in earlier diagnosing and treating in family members of patients.

Background : There has been a gradual increase in the number of newly diagnosed cases of Mycobacterium avium complex (MAC) pulmonary disease. However, the optimal therapeutic regimen for the disease has not yet established and there is no report about the treatment outcome of MAC pulmonary disease in Korea. This study examined the effect of clarithromycin-based regimen in patients with pulmonary MAC disease without a HIV infection. Materials and Methods : Fifty-six patients with pulmonary MAC disease were diagnosed according to the American Thoracic Society criteria from January 2000 to December 2003 at this hospital. Of these patients, 15 were treated with clarithromycin, rifampin, and ethambutol for more than 6 months, together with streptomycin initially (first 6 months) in 8 patients. Results : Six months after the treatment, the sputum cultures converted from positive to negative in 8 patients (53%) and the radiological findings improved in 10 (67%). At 12 months 4 patients (44%) achieved sputum negative conversion and 6 patients out of 9 patients (67%) who were treated for more than 12 months showed radiological improvement. Overall, the sputum findings converted to negative in nine patients (60%) who underwent medical treatment. A pulmonary resection was successfully performed in one patient. Only one patient discontinued the treatment due to side effects such as gastrointestinal intolerance and optic neuritis. Conclusion : A combined regimen containing clarithromycin is relatively safe and tolerable even in the elderly outpatients. However, the results of this combined chemotherapy were unsatisfactory and new companion drugs for MAC pulmonary disease are needed. A resection may be considered for localized disease.

Background : In Korea, polymerase chain reaction (PCR) test for M. tuberculosis has been used for the diagnosis of acid-fast bacilli (AFB) smear-negative tuberculosis in order to increase diagnostic sensitivity. However, there have been no data dealing with the clinical utility of PCR in AFB smear-positive patients to differentiate between M. tuberculosis and nontuberculous mycobacteria. Method : We retrospectively analyzed the PCR test results which have been performed in patients who had AFB smear-positive sputum but had ambiguous clinical manifestations of active tuberculosis. PCR test was done using $AMPLICOR^{\hat{a}}$ M. tuberculosis kit. The sensitivity, specificity, and positive and negative predictive values of the PCR test were calculated based on culture and final clinical diagnosis result. Results : Fifty-six consecutive patients (62 PCR tests) were included in the study. Active tuberculosis was diagnosed in 23 patients (41.0%), while 9 patients had NTM infection (16.0%). The sensitivity, specificity, positive- and negative-predictive value of PCR test were 88.8%, 86.8%, 76.1% and 94.3%, respectively, according to the culture result. In comparison, they were 91.3%, 100%, 100%, 94.3%, respectively, according to the final clinical diagnosis. All 15 patients with NTM isolates, including 6 patients who had other lung diseases but expectorated NTM isolate, were negative for PCR test. Conclusion : Even though tuberculosis is still prevalent in Korea, PCR test is useful to differentiate between M. tuberculosis and NTM in patients with AFB-smear positive sputum but with ambiguous clinical manifestations of active tuberculosis.

Purpose: To evaluate clinical results of the tumor prosthetic replacement for pathologic fracture of the proximal femur with extensive bony destruction due to metastatic bone tumors. Materials and Methods: From 2005 October to 2006 October, resection of proximal femur and tumor prosthesis replacement was performed for metastatic bone tumors extensively involving trochanteric area in 6 patients. The mean age of overall patients was 61(range, 48~77). Mean clinical follow up was 10.5 months (range, 6~16). Primary tumor consisted with multiple myeloma in 2 patients, lung cancer in 1, breast cancer in 1, transitional cell carcinoma of the renal pelvis in 1, unknown origin in 1 patient. $MUTARS^{(R)}$ proximal femur (Implantcast, Munster, Germany) were used in all cases. The functional evaluation in the lower extremities was performed with Musculoskeletal Tumor Society 1993 scores. The degree of pain relief after surgical treatment was assessed with Visual Analogue Scale (VAS). Results: At the final follow up, all of the patients survived. The mean lower extremities functional score of Musculoskeletal Tumor Society 1993 was 17.8(59.3%)(range, 12~25). VAS was improved to 2.5 from 8.5 after the surgical treatment. Ambulation was encouraged as soon as possible and mean duration after surgery for ambulation was 7.3(range, 3~16) days. Post-operatively, there was no surgical infection, periprosthetic fracture or loosening. Dislocation occurred in one out of six cases. Conclusion: Resection of proximal femur and tumor prosthesis replacement for metastatic bone tumors around proximal femur extensively involving trochanteric area seems to be safe procedure in view of post-operative complication, and effective for functional restoration as well as pain relief. Thus, it is accordant to the treatment principle of the metastatic bone tumors.
Pathologic changes and distribution of viral antigen as determined by immunohistochemistry were compared among 4-wk-old specific-pathogen free (SPF) chickens inoculated intratracheally with velogenic vis-cerotropic Newcastle disease virus isolated in Korea. Although the pattern of organ involvement and severity of lesion was different among chickens infected with different velogenic viscerotropic Newcastle disease (VVND) viruses, the pathological types of lesion was similar among the chickens. Severe lymphocytic necrosis and depletion were main histologic lesions in the immune related organs such as thymus, Fabricius bursa and spleen. The frequency of IP positive staining was variable depends on the types of tissues but not types of the kinds of VVND viruses infected. Brain, Fabricius bursa, thymus, cecal tonsil and trachea were IP positive with fairly high frequency and spleen, lung, proventriculus, intestine, pancreas, liver, kidney, heart and Harderian gland were with relatively low frequency. These results suggest that histologic evaluation and viral antigen specific immunohistochemical staining methods to determine virus distribution will be useful for pathogenic study of velogenic viscerotropic Newcastle disease virus infection in chicken.

Purpose : For evaluation of acute Mycoplasma pneumoniae(M. pneumoniae) pneumonia in children, we have studied the Mycoplasma indirect particle agglutination test, cold hemagglutinin test, ESR, CRP, and total white blood cell counts and it's differential count retrospectively. Methods : The total numbers of patients whom compatible with diagnostic criteria of acute M. pneumoniae peumonia were 56 cases from Jan. to Dec. 1997. The diagnostic criteria were 1) onset of fever(${\geq}38.0^{\circ}C$) and coughing were within 7 days, 2) rhonchi and/or role was audible on chest, 3) pneumonic infiltration on chest X-ray, and 4) M. pneumoniae indirect particle agglutination test titer was higher than 1:640, or initial titer was less than 1:640 but increased more than 4 folds after week. We classified the enrolled patients according to initial antibody titer, such as soup A(${\leq}1:640$) and group B(${\geq}1:320$). We compared group A and B by demographic findings, clinical symptoms and signs, and laboratory findings. Results : 1) The male and female sex ratio was 1:1.4, and average onset age was $5.8{\pm}2.96$ years. 2) The average body temperature on admission was $38.5{\pm}0.1^{\circ}C$ and productive coughing was noticed in 52 cases(93%). 3) The average total white cell counts were $10,470{\pm}877.0/mm^3$ in group B patients, which was significantly higher compared to $7,761{\pm}508.5/mm^3$ in group A(p<0.014). 4) The average value of ESR and CRP were within normal range in both group. 5) The most common site of pneumonic infiltration was right lower lobe of lung in both groups. 6) There were no correlation between antibody titer and cold hemagglutinine titer in patients and cold hemagglutination titer were less than 1:64 in 25 cases(45%). Conclusion : The clinical manifestations of pneumonia, findings of chest x-ray, and indirect particle agglutination test were useful on diagnosis of M. pneumoniae pnumonia onset within 7 days, but cold hemagglutinin test was a little diagnostic meaning.

Purpose : According to the 2008 WHO report, incidence, prevalence, and mortality of tuberculosis are decreasing globally. The 7th National Tuberculosis Survey of 1995 in Korea showed that the prevalence of tuberculosis was also decreasing. This study was performed to review the hospitalized childhood tuberculosis in a children's hospital over a 20 year period. Methods : Medical records of children <16 years of age hospitalized with the diagnosis of tuberculosis at the Seoul National University Children's Hospital between 1988 and 2007 were reviewed retrospectively. Changes in number of patients and involved sites were also analyzed by four 5-year periods. Results : Out of the 186 hospitalized patients, 59.1% were male. Median age at diagnosis was 5.5 years old (range, 10 days-15 years). The main involved sites included the lung (n=54, 29%) or pleura (n=12, 6.5%), central nervous system (n=49, 26.3%), lymph node (n=15, 8.1 %), bone and joint (n=9, 4.8%), gastrointestinal tract (n=5, 2.7%) or peritoneum (n=5, 2.7%), pericardium (n=2, 1.1%) and others (n=3, 1.6%). Total 32 patients (17.2%) showed miliary pattern. The proportion of hospitalization with newly diagnosed tuberculosis among all cause hospitalization decreased from 0.61% to 0.09%, comparing the period of 1988-1992 and 2003-2007 (P<0.001) and the incidence of hospitalized tuberculosis of any involved organs also decreased with a statistical significance. Conclusion : The data from a single children's hospital suggest that the number of hospitalized childhood patients with tuberculosis has decreased over a 20 year period in Korea.
Background: The prevalence of pulmonary tuberculosis remains high in several areas of the world, and pneumonectomy is often necessary to treat the sequelae of the disease. We retrospectively analyzed the morbidities, mortalities, and long-term outcomes after pneumonectomy for the treatment of tuberculous sequelae. Material and Method: Between 1981 and 2001, 94 patients underwent either pneumonectomy or extrapleural pneumonectomy for the treatment of tuberculous sequelae. There were 44 males and 50 females. The mean age was 40(16~68) years. The pathology included destroyed lung in 80, main bronchus stenosis in 10, and both lesions in 4. Surgical procedures were pneumonectomy in 47, extrapleural pneumonectomy in 43, and completion pneumonectomy in 4. Results: One patient died postoperatively due to empyema. Twenty-three complications occurred in 20 patients; empyema in 15(including 7 bronchopleural fistulas), wound infection in 5, and others in 3. Univariate analysis revealed presence of empyema, extrapleural pneumonectomy, prolonged operation time, and old age as risk factors of postpneumonectomy empyema. In multivariate analysis, old age and low preoperative FEV1 were risk factors of empyema. Low preoperative FEV1 was the risk factor of bronchopleural fistula(BPF) in univariate analysis. Low preoperative FEV1, positive sputum AFB, and presence of aspergilloma were risk factors of BPF in multivariate analysis. There were twelve late deaths. Actuarial 5-and 10-year survival rates were 94$\pm$3% and 87$\pm$4%, respectively. Conclusion: Pneumonectomy could be performed with acceptable mortality and morbidity, and could achieve good long-term survival for the treatment of tuberculous sequelae. In patients with risk factors, special care is recommended to prevent postoperative empyema or bronchopleural fistula.
