The ultrasound-guided fine needle aspirations were performed in order to diagnose a suspected neoplastic orinfectious diseases in 52 patients with focal liver disease. Of these, neoplastic lesions were suspected in 31patients and infectious lesions in 21 patients ultrasonically and/or clinically. The overall accuracy for bothsuspected malignant and infectious disease was 79%(41/52). The primary indication for fine needle aspiration wasto document the presense of malignancy and to avoid a diagnostic laparotomy, and to drain hepatic abscesses.Consequently we were convinced that the ultasound

BACKGROUND: Scuba diving has become increasingly popular in Korea. Medical problems are common with dives, especially decompression sickness(DCS). This study was performed to obtain an useful information of hyperbaric oxygen therapy in DCS in Korea. METHOD: We reviewed the 62 cases of Korean divers, who were diagnosed as DCS and received recompression therapy according to U.S. Navy Standard Recompression Treatment Table at Ocean and Underwater Medical Research and Training Center of ROK Navy, for 6 years from Jan. 1993 to Nov. 1998. RESULT: 1) the mean no-decompression limit excess time between type I DCS group(72.7 min.) and type II DCS group(92.8min.) showed significant difference. 2) The rate of symptoms appeared on surfacing and within 10min. after surfacing of type I and type II DCS were 41.4%and 72.7% respectively. 3) The cure late of type I and type II were 75.9%and 42.4% respectively. In type II DCS group, the cure rate of the group within 12 hour-delayed recompression treatment and the group above 12 hour-delayed treatment were 64.3%and time 26.3% respectively, and in type I DCS group, 100% and 66.7% respectively. CONCLUSION: These findings suggest that the education of safety, the strict observance of the standard decompression table, and the avoidance of excessive repeated diving are important for reducing the risk of diving related disease. And to offer proper management of DCS, there should be more multiplace hyperbaric oxygen chambers, the suitable transport system, and the specialist of diving medicine or hyperbaric medicine in Korea.

BACKGOUND: Transforming growth factor-beta (TGF-alpha) has been implicated in the pathogenesis of a number of kidney diseases. However, TGF-alpha is secreted in a latent form requiring extracellular modification to become biologically active. Recently, the activity of TGF-alpha has been assessed by the measurement betaig-h3, a novel TGF-alpha induced gene product. Thus we evaluated the pattern of urinary betaig-h3 expression in various glomerular diseases. METHODS: 64 patients with biopsy-proven primary glomerulonephritis (FSGS 6, HSPN 16, IgAN 20, MPGN I 7, and MesPGN 15), 10 patients with nephrotic syndrome and 12 healthy controls were enrolled in the study. A total 86 subjects (51 males, 59.3% and 35 females, 40.7%, mean age 13.9+/-4.28 years) constituted study population. First morning urine were collected and betaig-h3 in the urine was determined by indirect competitive ELISA (Regen Biotech Inc, Seoul, Korea). RESULTS: betaig-h3 excretion was significantly higher in the urine from patients with HSPN (27.5+/-6.46, p=0.002), with IgAN (40.83+/-12.27, p=0.026), with MPGN I (21.64+/-7.29, p=0.042), MesPGN (26.42+/-6.68, p=0.007). In patients with FSGS (21.65+/-17.12) and minimal change nephrotic syndrome (6.26+/-2.18), mean urinary betaig-h3 excretion was not significant higher than that in control group (3.56+/-0.78). CONCLUSION: Urinary betaig-h3 excretion was high in proliferative renal diseases. However, betaig-h3 excretion was not high in non-proliferative renal diseases.

A 30-year-old woman who was diagnosed as peripheral neuroblastoma by fine needle aspiration of a soft mass of the right upper arm is described. She presented a slowly growing, soft mass of the right upper arm for 1 month. The right humerus revealed no abnormal finding on X-ray. Ultrasonogram of the right upper arm revealed a well demarcated, smooth marginated solid mass without invasion of adjacent structures. Fine needle aspiration was done under the impression of soft tissue tumor with undetermined biologic behavior. The aspirates were highly cellular and the tumor cells were dispersed both singly and in clusters of varying size. The clusters occasionally showed a central capillary core and rosette-like structures. The tumor cells were small in size and had a small to medium amount of cytoplasm. Some of them revealed slender cytoplasmic processes. The nuclei showed distinct nuclear membranes, finely clumped chromatin and small conspicuous nucleoli. Cellular pleomorphism or mitotic figure was not definite. These cytologic findings were interpreted as a malignant, non-lymphomatous, small round cell tumor, most likely representing peripheral neuroblastoma or Ewing's sarcoma. Final diagnosis was confirmed by simple excision as peripheral neuroblastoma.

BACKGROUND: To standardize the histocompatibility testing among different laboratories, we have developed and performed a proficiency survey (external quality control) program in HLA typing with participation of nationwide HLA laboratories in Korea. METHODS: During a two-year period, four trials of proficiency survey were performed with 35-39 participating laboratories. Test number and items included in each survey were 3 HLA class Iantigen typings, 2 class II DNA typings, and 6 HLA crossmatch tests (3 cells x 2 sera). RESULTS: HLA class I serological typing was performed on a total of 12 whole blood specimens representing 7 HLA-A and 17 HLA-B antigens. More than 90% of the laboratories correctly identified 7 HLA-A (A2, A3, A11, A24, A26, A30, A33) and 13 HLA-B antigens (B7, B8, B13, B14, B27, B35, B48, B51, B52, B54, B58, B60, B61). Lower consensus (<90%) was obtained for B62, B67, B75, and B15 (B*1511). Considerable difference in antigen detection rate was observed between different commercial trays used. HLA class II DNA typing was performed on a total of 8 DNA specimens representing 13 HLA-DRB1 and 11 DQB1 alleles. For HLA-DRB1 typing (16-26 laboratories), correct assignment rate was very high (98%) for generic level, but lower (80%) for allele level. For DQB1 typing (5-8 laboratories), 100% consensus was obtained for allelic level. With respect to HLA crossmatching, detection rate of incompatibility was very low in the 1st trial. HLA crossmatch workshop on the standardization of typing methods was performed after the 1st trial, and thereafter the number of laboratories using sensitive methods were increased and the detection rate of incompatible crossmatch was much improved (1st 29-46%, 2nd 78-97%). CONCLUSIONS: Through these HLA typing proficiency surveys, standardization of test methods and improvement of typing results were obtained. A continuous survey program would play an important role for improving success rate of organ transplantations in Korea.

A squamous odontogenic tumor (SOT) is an epithelial originated benign tumor. It has been rarely reported and most was intramural type. We observed a case of SOT in the mandible. It was associated with the odontogenic cyst. It was shown positive to pancytokeratin and p53. Considering that the case was free from recurrence for 5 years after surgery, p53 positive did not seem to be related to the prognosis of the disease.

PURPOSE: To evaluate the efficacy of percutaneous catheter drainage for the treatment of postoperative lymphoceles following pelvic lymphadenectomy. MATERIALS AND METHODS: Between January 1995 and May 1996, 23 symptomatic lymphoceles in 20 patients who had undergone pelvic lymphadenectomy for uterine cancer were subjected to percutaneous catheter drainage under sonographic guidance. All the lymphoceles were confirmed by biochemical and cytological examination. When the amount of drainage decreased to less than 5-10ml/day and when the lymphocele was seen on US or sinography to have collapsed, the catheter was removed. US and sinography were performed to evaluate the efficacy of treatment at 1 week after catheter drainage, and all patients were followed up with US at 1, 3, and 6 months after catheter removal. RESULTS: On follow-up sonography, 20 of 23 lymphoceles (87.0%) were seen to have collapsed completely and three had recurred. Of these latter, two were treated by secondary percutaneous catheter drainage, and the other, which was asymptomatic and small, had collapsed spontaneously during the fifth months after catheter removal. Successful treatment of lymphocele was eventually achieved in all patients. The duration of catheter drainage ranged from 3 to 49 (mean, 22) days, and the size of lymphocele on initial sinogram varied from 5x4x3cm to 25x10x10cm; the total volume of drainage ranged from 300 to 17,240 (mean2,012)ml. Complications during the procedure and drainage arose in three cases. In one, there was secondary infection of the lymphocele, and in two, infection at the site of catheter insertion was seen; treatment involved changing the catheter and antibiotics. CONCLUSION: Percutaneous catheter drainage is thought to be a safe and effective alternative to surgery for the treatment of symptomatic lymphoceles following pelvic lymphadenectomy for uterine cancer.
