BACKGROUND: Oncogenes and EGF-Receptor(EGFR) may be involved n different stages of the multistep carcinogenesis process. A specific pattern of karyotypic abnormalities in solid tumors can be detected by cytogenetic methods. OBJECTIVE: This study is intnded to observe the cytomolecular kiologic chracterization of c-myc, erb B and EGFR genes in squasnous cell carcinoma(SCC) of the skin and cervix. METHODS: We have eytogenet,ically examined the short-term culturs from SCC. The rearrangement, amplification or expressi.on of erb B, c-myc, and EGFR genes were studied by Southern blot, analysis of genomic DNA and by slot blot analysis of tota! RNA extracted from biopsies of normal skin and SCC tissues. EGFR expression was examined immunohistochemially using monoclonal antibodies and the localizat,ion of the c-myc oncogene mRNA by in situ hybridization. RESULTS: A remarkably structural aberration was del 6(q21-qter) counted 20 metaphases among 28 metaphases ana1yzed. In nunierical aberration, all chromosomes were lost or gained randomly. Amenploid including triploid and tetraploid were observed in 8 metaphases, 6 tumor cells contained marker chromosome. In Southern blot analysis, rearrangement and amglificaton of EGFR in primary squamous cell carcinoma of cervix uteri and skin respectively. In slot blot analysis, the levels of c-myc, erb B and EGFR mRNA increaaed respectively 3.5, 2.5 and 2.8 times in SCC when compared to normal tissues. In immunoperoxidase stain, EGFR was present, in SCC where keratinocytes with strong cyto-plasmic staining but no membr, line labelling, where as in normal skin the were primarily present in t,he membrane and cytoplasm of basal cells. In situ hybridization with c-myc cDNAs allowed detection of grains representative of biotin labelled cDNA-mRNA hybrids in the frozden section of SCC tissues. CONCLUSION: These results suggest that specific patterns of karyotypir abnormalites, rearrangement, or amplification of EGFR gene, and overexpression of oncogenes and EGFR gene may be associated with the carcinogenesis of SCC.

Mitomycin C (MMC) trabeculectomy combined with extracapsular cataract extraction and posteor chamber intraocular lens implantation (glaucoma triple procedure, 30 eyes) was clinically compared with MMC trabeculectomy alone (30 eyes). The age, type of glaucoma, and preoperative number of medications were matched with the previous group (P>0.05). The mean preoperative intraocular pressures (IOPs) were 30.2+/-8.3mmHg (range, 22~56mmHg) in the glaucoma triple procedure group and 31.6+/-8.9mmHg (range, 22~57mmHg) in the trabeculectomy alone group (p=0.55). The mean postoperative IOPs were significantly higher in the glaucoma triple procedure group compared with the trabeculectomy alone group at all postoperative vistis (one month to nine months) (p<0.05). However, there were no statistically significant differences in the mean number of postoperative rise exceeding 30 mmHg within the postoperative one month tended to occur more frequently in the glaucoma triple procedure group (7 eyes (23%)) than the trabeculectomy alone group (2 eyes(7%)) (p=0.13). Conjunctival filtering blebs were significantly frequently observed in the trabeculectomy alone group than the glaucoma triple procedure group (28 eyes (93%), 20 eyes (67%), respectively, P=0.02) at 6 months postoperatively. The common postoperative complications were hyphema (4 eyes) and posterior capsular opacification (4 eyes) in the glaucoma triple procedure group and shallow anterior chamber(4 statistical difference was noted between these two groups (p>0.05). Although hypotensive effect of MMC on the glaucoma triple procedure was less than on the trabeculectomy alone, glaucoma triple procedure using MMC could be recommended to be safe and effective on controlling the high IOP for treating glaucoma patients with coexisting cataract.

We report herein a case of primary cutaneous diffuse large B-cell lymphoma with multiple skin lesions in a Korean woman. A 56-year-old woman presented with rapidly growing multiple sub-cutaneous nodules in her right flank and right upper arm. Microscopic examination of skin biopsy specimen showed diffuse infiltrates of large atypical lymphocytes with vesicular nuclei, prominent nucleoli and moderate degree of mitotic figures in deep dermis and subcutis. Immunophenotypic studies revealed the lymphoid infiltrates reacted with CD45, CD20 and bcl-2 protein, but none of the sections expressed CD3, bcl-6 protein and CD30. In physical examination and staging work-up, we could not find any other extracutaneous or systemic involvement. She was treated with 2 cycles of high-dose multiagent chemotherapy with the Vanderbilt and the BEAM regimen combined with the autologous peripheral blood stem cell transplantation. Until now, 10 months after termination of treatment, she has shown improvement of all skin lesions and no development of extracutaneous disease.

We investigated the intraocular pressure(IOP) lowering effect and side effects of 2% dorzolamide(Trusopt) as adjunctive therapy in 18 eyes of 11 glaucoma patients and 10 eyes of 10 normal subjects. For those patients who have taken beta-blocker at least 2 weeks in glaucoma or ocular hypertension, we measured IOP before dorzolamide start and after dorzolamide instillation, every 2 hours from 10 AM to 4 PM for 3 weeks and evaluated the side effects. In normal subjects, we Measured the same method of IOP for 2 weeks and evaluated the side effects. In patients with glaucoma or ocular hypertension, mean IOP was lowered 4.4 mmHg after 2% dorzolamide instillation(P<0.01). There was no change in pulse rate, blood pressure and corneal sensitivity before and after instillation. There was no significant IOP lowering effect on normal subjects(p>0.05). The common side effects were bitter taste, burning sensation, redness, tearing and dryness. Above these results, we think 2% dorzolamide is effective as adjunctive therapy in glaucoma and more follow-up and treatment is needed to establish the fact.

PURPOSE: Percutaneous transluminal angioplasty(PTA) with a balloon catheter is a standard method of treatment for membranous obstruction of inferior vena cava(MOIVC). But, correct therapeutic approach has not been established for MOIVC patients whose lesion is associated with extensive thrombotic IVC occlusion. We tried to treat MOIVC associated with or without thrombus. MATERIALS AND METHODS: We treated 13 cases of MOIVC(associated with thrombus in 7 cases, no thrombus in 6 cases) with PTA, thrombolysis and self-expandable metallic stents. RESULTS: PTA was successful in 8 cases, but failed in 5 cases. The recurred cases were retreated with PTA, but follow up study revealed recoiling restenosis in 4 cases and intimal hyperplasia in 1 case at previous PTA site which could be overcome with a self-expandable metallic stent. The complication were occurred in 3 cases which were hemothorax, hemopericardium, and hemoperitoneum respectively. However, those were resolved by conservative treatment only. CONCLUSION: Recanalization and dilatation could be done in MOIVC patients with or without thrombosis for improvement of patient's symptom. Gianturco self-expandable metallic stent is sueful in treatment of recurred MOIVC after balloon dilatation and preventing reocclusion of the IVC after PTA.

PURPOSE: Though clavicle fractures are the second most common fractures to occur in active adults, there have been a few epidemiological studies conducted on the Korean population in recent years. To better understand clavicle fractures, an epidemiological study reflecting the changes in current life style and injury mechanism may be important. Hence, the purpose of this study was to conduct an epidemiological study on the Korean population. MATERIALS AND METHODS: This was a retrospective study of 973 patients (977 cases) who presented with clavicle fractures from January 2000 to August 2015. Radiological results were classified by the Allman system-3 groups and 7 subgroups. The study collected information regarding gender, age at the event of injury, injury mechanism, other associated injuries, occurrence rate of each year, and seasonal variation. RESULTS: The study consisted of 627 male patients (64.4%, 1 bilateral case) and 346 female patients (35.6%, 3 bilateral cases). The mean age at the time of injury was 31.8±24.9 years (male, 31.2±22.6 years; female, 32.7±28.7 years). Midshaft clavicle fractures (Allman group I) were the most common with 758 cases (77.6%). There were 397 cases with displacement (40.6%). The occurrence of clavicle fractures decreased with increasing age in male patients and showed a bimodal distribution in female patients. Injury due to a fall from standing height was the most common mechanism of injury. There were 61 cases (6.2%) who had other associated injuries and the most common associated injury was a rib fracture. The occurrence of clavicle fractures increased with time, and falling was associated with the highest occurrence rate of clavicle fractures. CONCLUSION: The mean age of clavicle fracture was 31.8 years in a recent 15-year period. The occurrence of fracture in male patients was 1.8 times than female patients, primarily occurring as midshaft fractures. There were more cases of displacement than minimally displaced cases. The most common injury mechanism was a fall from standing height, and the occurrence of clavicle fractures has shown an increasing trend recently.

BACKGROUND: It has been reported that younger patients with lung cancer have characteristic features that differ from those in older patients. The prognosis for young patients with this disease is controversial. This study aimed to determine the clinicopathological characteristics, the survival rate, and the risk factors associated with the overall survival rate in younger patients with lung cancer. METHODS: The records of 120 young(age≤40) patients with histologically confirmed lug cancer in the Korea Cancer Center Hospital(KCCH) between Jan. 1992 to 1998, 120 older(age>40) patients were randomly selected as the controls. RESULTS: More female patients(45.0% vs. 20.0%, p<0.001) and more adenocarcinoma cases(64.2% vs. 38.3%, p<0.001) were found in the younger group, when compared to the older patients. In NSCLC, advanced disease(stage III B and IV) was more common in the younger patients(90.2%) than in the older patients(62.7%) (p<0.001). The Median survival was 8.6 months in the younger patients and 12.2 months in the older(p=0.003). In a multivariate analysis, only the advanced-stage was an independent negative prognostic factor. CONCLUSION: Lung cancer in the younger age group presents with a more advanced stage resulting in a poor survival rate, which suggests that lung cancer in this population is more aggressive than in older patients.
