Parachuting has become progressively a very popular recreational sports in foreign developed nations, and subsequently injury caused by it is getting more frighten and sometimes severe. Authors in this study clinically analysed 306 cases of parachuting injury who were treated at the department of orthopaedic sugery, C.A.F.G.H. during 3 years period from March, 19xx to February, 19 XX. There results were as followings: l. Of 306 cases, 268 had fracture, 38 soft tissue injuries. 2. Of 268 fracture cases, 208 cases had injuries in the lower extremity, 48 cases in trunk, 15 cases in upper extremity. 3. The most common associated injury was the head injury (26%). 4. The most common injured site was ankle and foot (57.5%), the next spine and pelvis (16.9%). 5. Through this study, it is said that parachuting is a dangerous sports, and the injury caused by parachuting may be largely preventable, if with adequate practical instruction, coaching and wearing protective garments.

Primary central nervous system(CNS) lymphoma is an uncommon neoplasm which is considered to be radiosensitive. We have recently experienced one of such cases with a history of systemic lymphoma(diffuse histiocytic lymphoma) of the left cheek and left forearm in a 56-year-old man. Chief complaints include headache and generalized weakness for 1 month. MRI(magnetic resonance imaging) revealed an enhancing irregular mass lesion in both the basal ganglia and corpus callosum with minimal surrounding brain edema. CSF analysis and cytology revealed no specific abnormal findings. Without brain biopsy, we concluded that the lesion was a primary CNS lymphoma based on the fact that the patient have had a history of diffuse histiocytic lymphoma and MRI findings were compatible to primary CNS lymphoma. He was treated with dexamethasone for 2 weeks and 3900 cGy radiation therapy for 5 weeks. He improved gradually, and control MRI after radiotherapy showed complete resolution of the lesion.

BACKGROUND: PCR-based reverse blot hybridization assay (PCR-REBA) has high sensitivity and specificity, can be performed directly on nail samples, is relatively cheaper than other molecular biologic methods, and is useful for diagnosing onychomycosis. OBJECTIVE: This study aims to compare the diagnostic efficacy of fungal culture and REBA Fungus-ID® which is a commercial PCR-REBA-based kit used for onychomycosis diagnosis. METHODS: Fifty nail samples were collected from 50 patients diagnosed with onychomycosis via direct microscopic examination using KOH preparation, and subjected to fungal culture and REBA Fungus-ID® test. RESULTS: The sensitivity of conventional fungal culture and REBA Fungus-ID® was 56% and 100%, respectively. In REBA Fungus-ID®, 43 of 50 samples were found to be infected with Trichophyton rubrum. Four of the remaining 7 samples were identified as infected with Trichophyton spp., one with Trichophyton mentagrophytes, and two revealed a panfungal DNA sequence. In fungal culture, 28 of 50 samples showed growth, of which 18 samples were identified as T. rubrum, 3 as Rhodotorula mucilaginosa, 3 as Cladosporium spp., 1 as Cyphellophora europaea, 1 as Penicillium cvjetkovicii, 1 as Lachnum soppittii, and 1 as non-dermatophytic mold. REBA Fungus-ID® and fungal culture were identical in 20 cases (40%). The non-dermatophytic fungi identified in fungal culture were considered contaminants. CONCLUSION: Nail specimens can be used directly for REBA Fungus-ID®, which has a high sensitivity for onychomycosis diagnosis. Therefore, it can be considered useful for diagnosis and identification of the causative organism in mixed infections like onychomycosis.

Multiple myeloma is usually restricted to bone marrow, but extramedullary involvement can occur in the form of plasmacytomas. Several cases of multiple myeloma which developed into mutiple extramedullary involvements have been reported. We report a case of extramedullary plasmacytomas of posterior mediastinum, and gingiva, which developed in the course of mutiple myeloma in a 57-year-old man. The patient progressed to fulminant hepatic failure resulting in rapid fatal outcome.

BACKGROUND: This study was performed to identify the incidence and prognostic significance of chromosomal abnormalities as well as clinical significance of immuno phenotype in patients with acute myelogenous leukemia (AML). METHODS: The chromosomal abnormalities, immunophenotype and their hematologic/clinical correlations were studied in 68 patients with de novo AML admitted to Pusan National University Hospital between January 1996 and December 2000. 47 of 68 patients had received induction chemotherapy and we analysed the response of treatment according to the karyotype pattern and immunophenotype. RESULTS: The karyotypic patterns were divided into three groups; favorable (t (8;21), t (15;17) and inv (16); n=19, 28%), poor (-5, del (5q), -7, der (1;7), abn (3q) and complex karyotypes; n=11, 16%) and intermediate group (other abnormalities or normal karyotype; n=38, 56%). The incidence of chromosomal abnormalities was 56% (38/68) and overall complete remission (CR) rate of 47 evaluable patients was 64%. The CR rates of favorable, intermediate and poor groups were 88%, 59% and 44%, respectively (p=0.021). The median survival time of all patients was 7 months, those of poor and intermediate groups being 2 months and 6 months. The median survival time of favorable group was not reached (p=0.008). The overall 5 year survival rate was 38% and those of favorable, intermediate and poor groups were 68%, 31% and 9%, respectively (p=0.009). Expression of CD7, CD14, CD33, CD34 and terminal deoxynucleotidyl transferase had no impact on CR rate and overall survival. In multivariate analysis, both age and chromosomal abnormalities influence significantly on prognosis. CONCLUSION: Cytogenetic study is important in predicting the outcome of patients with AML. And the treatment must be tailored according to the result of cytogenetics such as this study.

BACKGROUND/AIMS: Controversy remains over the optimal approach to preoperative biliary drainage in patients with resectable perihilar cholangiocarcinoma. We compared the clinical outcomes of endoscopic biliary drainage (EBD) with those of percutaneous transhepatic biliary drainage (PTBD) in patients undergoing preoperative biliary drainage for perihilar cholangiocarcinoma. METHODS: A total of 106 consecutive patients who underwent biliary drainage before surgical treatment were divided into two groups: the PTBD group (n=62) and the EBD group (n=44). RESULTS: Successful drainage on the first attempt was achieved in 36 of 62 patients (58.1%) with PTBD, and in 25 of 44 patients (56.8%) with EBD. There were no significant differences in predrainage patient demographics and decompression periods between the two groups. Procedure-related complications, especially cholangitis and pancreatitis, were significantly more frequent in the EBD group than the PTBD group (PTBD vs EBD: 22.6% vs 54.5%, p<0.001). Two patients (3.8%) in the PTBD group experienced catheter tract implantation metastasis after curative resection during the follow-up period. CONCLUSIONS: EBD was associated with a higher risk of procedure-related complications than PTBD. These complications were managed properly without severe morbidity; however, in the PTBD group, there were two cases of cancer dissemination along the catheter tract.

BACKGROUND: Although idiopathic cardiomyopathies(i-CMP) are very important in all age groups, the epidemiology of i-CMP in children has not been well defined. A retrospective study in Korean children was performed in 1998 to obtain basic data on i-CMP. MATERIAL AND METHOD: The medical records of all patients aged birth to 15 years from the hospitals where pediatric cardiologists worked were reviewed to obtain information on i-CMP. Pediatric cardiologists from a total of 22 hospitals were participated in reviewing the medical records of their patients and filling up the protocol. The data were pooled to the study committee and reviewed. RESULTS: Of the 278 cases with i-CMP, there were dilated cardiomyopathy (d-CMP) in 182 (65.4%): hypertrophic cardiomyopathy (h-CMP) in 74 (26.6%): restrictive cardiomyopathy (r-CMP) and unclassified in 17 (6.1%) and 5 (1.9%) each. The average annual occurrence of new cases as a whole was 2.65 per 100,000 (95% CI: 1.5-3.7): d-CMP, 1.73/100,000/year (95% CI: 0.73-2.73): h-CMP, 0.71/100,000/year (95% CI: 0.35-1.07): r-CMP, 0.16/100,000/year (95% CI: 0.02-0.3). The median age at the time of diagnosis was 11 months in d-CMP: 3.0 years in h-CMP: 6.9 years in r-CMP. The survival rate in d-CMP was 76% at 1 year, 72.5% at 2 year, 70% at 5 year. There was no difference in survival rate according to age (in d-CMP, between children less than 2 years of age and over 2 years of age (74% vs. 79% at 1 year: 67% vs. 76% at 5 year, p=NS): in h-CMP, between children less than 1 year of age and over 1 year of age (84% vs. 96% at 1 year: 63% vs. 81% at 5 year, p=NS)). R-CMP showed the worst survival rate (72% at 1 year, 30.2% at 5 year). CONCLUSION: In spite of the inherent defects of retrospective analysis, this study provides the useful epidemiological data in children with i-CMP. However, more systemic approach is needed to define the nature of the i-CMP in children.
