BACKGROUND: In the Republic of Korea, there had been no reports about indigenous malaria cases since 1984 until a vivax malaria case was detected in 1993. Thereafter fram 1993 to 1996, 486 malaria cases were reported. Most of the patients were soldiers in the northern militarized zone. However, since 1997, several patients with malaria were detected in Kang Hwa where there had previously been no report of malaria cases. It is our intent to report the 16 cases diagrnosed in Kang Hwa Community Hospital from January 1, 1997 to August 10, 1998. METHODS: Medical records of the malaria cases from January 1, 1997, to August 10, 1998 in Kang Hwa Community Haspital were reviewed. All of the patients had no histories of traveling abroad, drug abuse or blood transfusion. They were all civilians. Laboratory studies including blood cell count, routine chemistry and platelet-associated IgG(PAIgG) and abdominal sanography were taken. RESULTS: All of the patients were diagnosed with malaria by blood smears. Common symptams were fever(100%), headache(94%), rigors(81%), myaJgia(56%), nausea or vomiting(44%), alternate day fever (25%), left flank pain(19%), diarrhea(13%), and abdominal pain(13%). Splenomegaly was detected in 92% of cases by sonography. Laboratory findings included leukopenia(37.5%), anemia(37.5%) and thrombocytopenia(81.3%). Platelet-associated IgG was elevated in 1 of 5 thrombocytopenic patients who had had the laboratory study performed. All recovered withaut complications. CONCLUSIONS: Cases of indigenous malaria have been progressively increasing in the Republic of Korea. Fortunately, patients responded well to treatment, but continued interest will be required in the future.

PURPOSE: To report two cases of successful acellular dermal allograft transplantation for scleromalacia following pterygium excision. CASE SUMMARY: A 72-year-old female patient developed scleromalacia on the nasal side of the right eye, and a 79-year-old female patient developed scleromalacia with inflammation on the nasal side of the left eye. They had previous histories of pterigia removal on the sites of scleromalacia. Acellular dermal allograft (AlloDerm(R), Lifecell, NJ, USA) transplantations were done. After the operations, inflammation and pain ameliorated and the grafts survived without any particular complications. CONCLUSIONS: In treating scleromalacia, the transplantation of acellular dermal allografts produced relatively satisfactory results without undesirable problems commonly encountered when using conventional materials.

PURPOSE: This study examined the postoperative long-term results of the reconstruction of orbital wall fracture using Macropore(R). METHODS: The long-term results for 10 patients who were diagnosed with orbital wall fracture and received the repair of orbital wall fracture using Macropore(R), were examined postoperatively after an average of 23.5 months. RESULTS: The mean difference in orbital volume between the fractured orbit and the unaffected orbit after an average of 23.5 months postoperatively was 1.01+/-0.70 cm3 (4.75+/-2.92%), which slightly increased compared to 0.70+/-0.52 cm3 (3.26+/-2.10%) immediately after the operation, although the difference was not statistically significant (p-value=0.190). At the last follow-up, the shape of Macropore(R) was not observed in 3 out of the 10 patients, and intense ossification was observed at the site of fracture in 6 patients. At the last follow-up, one patient showed 1.5 mm enophthalmos, and the other patients did not show the occurrence of diplopia or the progress of enophthalmos. CONCLUSIONS: According to the long-term results of the reconstruction of orbital wall fracture, Macropore(R) is considered an implant that produces a safe and satisfactory effect without notable complications.

BACKGROUND: Because of the common etiologic factor, such as smoking, lung cancer and chronic obstructive Pulmonary disease are often present in the same patient. The preoperative prediction of remaining pulmonary function after the resectional surgery is very important to prevent serious complication and postoperative respiratory failure. 99mTc-MAA perfusion scan has been used for the prediction of postoperative pulmonary function, but it may be inaccurate in case of large V/Q mismatching. We compared 99mTc-DTPA radioaerosol inhalation scan with 99mTc-MAA perfusion scan in predicting postoperative lung function. METHOD: Preoperative inhalation scan and/or perfusion scan were performed and pulmonary function test were performed preoperatively and 2 month after operation. We predicted the postoperative pulmonary functions using the following equations. Postpneumonectomy FEV1=Preop FEV1x% of total function of lung to remain RESULTS: 1) The inhalation scan showed good correlations between measured and predicted FEV1, FVC and FEF25-75%. (correlation coefficiency; 0.94, 0.91, 0.87 respectively). 2) The perfusion scan also showed good correlations between measured and predicted FEV1, FVC and FEF25-75%. (correlation coefficiency; 0.86, 0.72, 0.97 respectively). 3) Among three parameters, FEV1 showed the best correlations in the prediction by lung scans. 4) Comparison between inhalation scan and perfusion scan in predicting pulmonary function did not show any significant differneces except FVC. CONCLUSION: The inhalation scan and perfusion scan are very useful in the prediction of postoperative lung function and don't make a difference in the prediction of pulmonary function although the former showed a better correlation in FVC.

PURPOSE: To determine the antitumor activity of VACOP-B regimen for advanced non- Hodgkin's lymphoma (NHL) in terms of complete response rate, disease free survival, and overall survival, to assess the toxicities of this regimen, and to analyze the prognostic factors influencing the treatment results.Patients and methods: Between Apr. 1991 and Aug. 1993, thirty-six previously untreated patients with the intermediate or high grade NHL were treated with VACOP-B (etoposide/doxorubicin/cyclophosphamide/vincristine/prednisolone/bleomycin) combination chemotherapy. In case of initial bulky disease or residual disease after chemotherapy, radiation therapy of involved field was added. RESULTS: Complete response (CR) was achieved in 69% (25/36) of the eligible patients after VACOP-B chemotherapy, and 5 of 11 patients who remained in partial response (PR) after chemotherapy achieved CR after additional radiation therapy of involved field, resulting in 83% (30/36) of CR rate. With a median follow-up of 47.2 months, the disease free survival was 1~42.1+ months, and its median was 24 months. The range of survival time was 7~49.1+ months, and the median survival time was not reached at this time. The projected 3-year survival rate was 70%. Leukopenia was observed in 43% of chemotherapy cycles and thrombocytopenia in 2.3%. However, no treatment-related death was observed. For non-hematologic toxicities, nausea and vomiting were observed in 58% of patients, stomatitis in 58%, peripheral neuropathy in 58%, pulmonary toxicity in 3% and congestive heart failure in 3%. These toxicities were tolerable and all reversible. The prognostic factors influencing the complete response rate were performance status of patient (p=0.026) and relative dose intensity of cyclophosphamide (p=0.013). CONCLUSION: VACOP-B regimen is an effective and tolerable regimen for the intermediate and high grade NHL. And long term follow-up and phase III study will be needed for evaluation of these results compared to previous other treatment modality.

Small cell lung cancer(SCLC) is frequently associated with paraneoplastic syndromes, which occur in approximately 20% of patients at presentation. Clinical Cushing's syndrome secondary to ectopic ACTH production is uncommon, occurring in approximately 5% of all SCLC patients. However, biochemical evidence of hypercortisolism can be detected in up to 50% of patients. Patients with Cushing's syndrome from ectopic ACTH production show hypertension, weakness, hyperglycemia, and hypokalemic metabolic alkalosis, but differ from patients with classic Cushing's disease in that symptoms develop more rapidly. Ectopic ACTH production is associated with a poor response to chemotherapy, short survival, and a high risk of treatment-related complications. We report a case of Cushing's syndrome associated with ectopic corticotropin production in 59-year-old male patient with extensive stage of SCLC.

The purpose of the study was to identify the relationships Total Quality Management (TQM) performance, job satisfaction, and organizational commitment among dietitians in business and industry foodservice. A total of 300 dietitians working in business and industry foodservices in Seoul and Gyeonggi province were surveyed using a self-administrated questionnaire and 203 responses were obtained. The data were analyzed using SPSS Windows (Ver. 12.0) for descriptive analysis and reliability analysis, and AMOS (Ver. 5.0) for structural equation modeling. The respondents were all female, 56.7% single, and 71.4% under regular employment. By foodservice management type, 52.7% of the foodservice operations were self-operated. The majority of the operations provided meals more than twice a day (73.9%), and 70.4% offered a non-selective menu. The dietitians of the contracted foodservices tended to have higher TQM performance scores than those of the self-operated foodservices (P<0.01). There were no significant differences in job satisfaction and organizational commitment scores by the type of the foodservice management. TQM performance was found to have a positive effect on job satisfaction, and job satisfaction affected organizational commitment for both the self-operated and contracted foodservices. A relationship between TQM performance level and organizational commitment of self-operated foodservices was not found. On the other hand, TQM performance level was the principal significant factor for increasing the organizational commitment of contracted foodservices. This research suggests that business and industry foodservices need to improve TQM performance to enhance job satisfaction and organizational commitment of foodservice dietitians and to develop specified TQM strategies that can be applied to each type of foodservice management.

OBJECTIVES: Multiple lung cancers and/or precancerous lesions can be developed because many bronchi are exposed to carcinogens simultaneously according to the concept of 'Field Cancerization'. We had performed a careful bronchoscopic examination and analysed the patients of double bronchial lesions who received the separate pathologic evaluation. METHODS: We studied 21 patients of double bronchial lesions among 1855 patients of bronchoscopic examination from April 1990 to December 1993 in Korea Cancer Center Hospital. We classified the patients into three groups(double malignancies of different histology, double malignancies of same histology, and combination of malignant and benign lesions) and analysed the histologic type, location, radiologic findings, and clinical parameters. RESULTS: Among 21 patients, six patients had double malignancies of different histology, eight had double malignancies of same histology, and seven had combination of malignant and benign lesions. Out of 14 double malignant cases, 11 cases are considered as synchronous multiple primary lung cancers. Combination of squamous cell carcinomas was found in 5 cases, combination of small cell carcinoma and squamous cell carcinoma was found in 4 cases. Combination of adenocarcinoma and squamous cell carcinoma and combination of squamous cell carcinoma and poorly differentiated carcinoma were found in 1 case respectively. All patients of synchronous multiple primary lung cancers were male and had long smoking history(average 40 pack years). Among 21 cases of double bronchial lesions, only one lesion could be detected by prebronchoscopic radiologic examination including chest CT in 15 cases. CONCLUSIONS: The presence of double bronchial lesions including multiple primary lung cancers and the limitation of radiologic examination to detect early bronchial lesions encourage us to examine the whole bronchi carefully and to perform pathologic evaluations.

BACKGROUND: Ketamine hydrochloride, NMDA receptor antagonist is a potent analgesic and anesthetic. Other analgesics, like opioid, have been shown to effectively relieve postoperative pain when infused into epidural space, but effects of ketamine hydrochloride infused into epidrual space for postoperative pain control is still controversial, and therefore the present study was undertaken. METHODS: Ninety adult patients (ASA I or II) scheduled for upper abdominal and chest surgery were randomized into ketamine and fentanyl groups. For all patients, informed consent was obtained preoperatively. Anesthesia was induced with thiopental sodium/succinylcholine and maintained with nitrous oxide/oxygen/enflurane. Skeletal muscle relaxation was maintained with vecuronium. Epidural catheterization was done after operation. Ketamine group received epidural bolus of 0.1% bupivacaine 10 ml followed by continuous epidural infusion of 0.1% bupivacaine 100 ml containing ketamine 200 mg. Fentanyl group received epidural bolus of 0.1% bupivacaine 10 ml containing fentanyl 100 microgram followed by continuous epidural infusion of 0.1% bupivacaine 100 ml containing fentanyl 600 microgram. Continuous infusion rate was 2 ml/hr in both groups. Analgesic effects were assessed using VAS (visual analogue score), PHS (Prince Henry score) and PRS (pain relief score). Side effects and number of patients using additional analgesics were evaluated. RESULTS: Analgesic effects were significant in both group after drug administration. But fentanyl group had greater analgesic effects than ketamine group. Fentanyl group experienced side effects such as pruritus (27 cases), nausea and vomiting (9 cases). Ketamine group had side effects such as nausea and vomiting (13 cases). Number of patients using additional analgesics were seven and twenty-four in the fentanyl and ketamine groups, respectively. CONCLUSIONS: We conclued continuous epidural infusion of ketamine had fewer analgesics effect at early state of postoperative pain than fentanyl.
