BACKGROUND: Recently, there are so many newly developed equipments to detect blood gas analysis with serum electrolytes. And then, so many important parameters are quickly reported from laboratory department. So, many clinicians use the data to manage the critical patient. We attempted to detemine the correlation coefficient and adjustment equation. METHODS: Total 68 patients results of Na, K that are cheked using arterial whole blood(288 blood gas system) and venous serum electrolytes analyzer(NOVA 6) were evaluated and we detemined the coefficient of two methods from April to September, 1995. RESULTS: The correlations between the results obtained with NOVA 6 and that of 288 blood gas system were excellent for both Sodium and potassium(r>0.95, p<0.001 in both). In this study, we make the regression equation to adjust the differences between the two methods. Na : y=1.004190X+7.656643(r=0.9637, p<0.001) y=venous serum Na, x=arterial whole blood Na K: y=0.994831X+0.489631(r=0.9545, p<0.001) y=venous serum K, x=arterial whole blood K. CONCLUSIONS: Specimen(whole blood, serum), kind and content of heparin also affect the results of electrolytes. And then, the report of the result after adjustment of them using above equation will provide reinforcement of the efficacy of the results using arterial whole blood specmen. We recommend it especially for emergency laboratories for critical test.

Germ cell tumors(GCT) are not infrequently encounted tumor in pediartic age group. In order to study the clinical behaviors of the disease, we reviewed 29 cases of GCT diagnosed and treated at Kosin Medical Center in the period of 7 years form Jan. 1984 to Dec. 1991 and the results are summarized as follows: 1) The age distribution is the highest between 10 and 15 years(45%) and girls have 1.9 times higher frequency than that of boys. 2) The most frequent primary site of GCT was ovary(15). The next common primary site was testis(5), pineal body(4), sacrococcygeal region(2), retroperitoneum(1), soft palate(1), anterior mediastinum(1) in descending order of frequency. 3) In the pathological analysis of tumors, the most frequent type was mature teratoma(12). The next common type was endodermal sinus tumor(6), immature teratoma(5), dysgerminoma(3), mixed type(2), and choriocarcinoma(1)in descending order of frequency. 4) All the 5 cases of EST have elevated serum levels of alpha-fetoprotein. Two of the three dysgerminoma, one of the two mixed type tumors both of which have germinoma components, and one choriocarcinoma have elevated serum levels of beta-HCG above the age related physiological levels. 5) Among 17 cases of malignant GCT, 9 cases have metastatic areas such as regional lymph nodes, scrotum, pleura, retroperitoneum, omentum and lumbar spine. 6) All except on case of immature teratoma in the anterior mediastinum underwent surgery. Chemotherapy was given to 12 of 17 malignant GCT and radiotherapy was given to 4 of 17 malignant GCT. 7) Among the 4 expired cases within 12 months of follow up, three were originated from pineal body, which had been underwent simple V-P shunt or incomplete resection, and one case was metastatic immature teratoma of anterior mediastinum to the pleura which had not been undergone surgery. Finally, in review of literature and or cases, the survival of properly managed GCT except some of those difficult surgical access is relatively good. To continue the survival of children of GCT to be impoved, we should use all the treatment modalit properly with more positive outlook about the disease.

A 12-year-old boy developed cholestatic hepatitis with Steven-Johnson syndrome following the use of amoxicillin. The skin lesion and general condition were improved over 2 weeks, but jaundice was gradually aggrevated. We performed liver biopsy, on 30th hospital day, which showed cholestatic hepatitis. The patient improved gradually and liver function was normalized 5 months later.

From Sept. 1987 to Mar. 1993, 14 cases of pelvic bone tumors took surgical treatment. Male to female ratio was 7:7, with an average age of 31.9 years. Pathological diagnosis were chondrosarcoma 7(1 ; secondary), metastatic thyroid cancer 2, and each one case of giant cell tumor, desmoplastic fibroma, metastatic synovial sarcoma, malignant fibrous histiocytoma(MFH), and enchondroma. According to the Enneking's classification for the type of surgical resection, we performed 4 cases of type II+III resection, 4 type IA, 2 type I+II, 2 type III, and each one of II and IIA+III. Types of reconstruction were hip fusion(3 cases), heat treated autogenous bone graft combined with total hip replacement arthroplasty(4), bone graft(2), cement spacer(1) or saddle prothesis(1). Simple resection was done for 3 cases. Wide surgical margin was achieved in 12 cases, marginal margin in 1 and intralesional magin in 1. Complications occurred in 3 cases(21.4%) : 1 graft failure ; 1 lymphedema ; and 1 delayed union. The average follow-up period was 27.4(8-60) months. During follow up, lung metastasis developed in MFH case but no local recurrence was noted in all. By the criteria of American Musculoskeletal Tumor Society(MSTS), the average score for functional activities was 21(70% of normal). The function of the extremity with reconstructed or undestroyed pelvic ring was better than that with disrupted pelvic ring(functional scores ; 24.6 vs 12.3 respectively). Due to the Korean life style using hypocaust, fused hip was not good for indoor activity. For the malignant pelvic bone tumor not involving femoral neurovascular bundle, limb-salvage using internal pelvectomy and reconstruction of pelvic ring can be indicated as a surgical procedure, instead of the hindquarter amputation.

From Jan. of 1990 to Dec. of 1992, we have experienced three cases of multiple primary malignant neoplasms originated from different histogenesis, in the Department of Orthopedic Surgery of Korea Cancer Center Hospital. Liposarcomas, malignant fibrous histiocytoma were combined with renal cell carcinoma, mucinous cystadenocarcinoma of ovary or prostatic cancer. With Moertel's classification, synchronous tumors were found in 2 cases and metachronous in 1 case. Synchronous tumors were 2 liposarcomas-renal cell carcinoma or mucinous cystadenocarcinoma of ovary. Metachronous tumors were malignant fibrous histiocytoma-prostate cancer. We couldn t find any family history among them. The causes of these multiple malignancies were considered as the individual predilrection to tumors.
