Serous cystadenoma of the pancreas, also known as microcystic adenoma or glycogen-rich cystadenoma, is an unusually benign tumor. It is usually large and composed microscopically of many small cysts lined by small, cuboidal or flattened cells containing abundant glycogen. It has been suggested that serous cystadenoma probably arise from the ductular cells or centroacinar cells. Herein, we report on a case of serous cystadenoma of the pancreas in a 55-year-old female. The tumor, measuring 13.5x11.5x10.0 cm, was located in the head of the pancreas and the cut surface revealed a sponge-like appearance due to innumerable tiny cysts containing clear serous fluid. Microscopic analysis showed cystic spaces lined by cuboidal cells with intracytoplasmic glycogen.

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.

The expression of p62"' and p2l can be seen in many solid tumor, but the pattern and incidence of expression were different according to organ, countries, and examiners, thus it is not definitely defined. Total 67 colorectal carcinoma in paraffin sections are analysed by immunohistochemically for evaluation of the p62and p21- expression according to the age, sex, chief complaints, location, differentiation, modified Dukes stage, using the specific monoclonal antibodies. The results were summarized as follows : The age of patients ranged from 32 years to 82 years. The mean age was 57.6 years. The expression of p 62y' and p21 was not correlated with age. Male was 29 cases(43.3%) and female was 38 cases(56.7%). The male to female ratio was 1:1.31. The and 95.0% in moderately differentiated adenocarcinoma, 90.0% and 90.0% in poorly differentiated <,;, adenocarcmoma, 100.0% and 100.0% in mucinous carcinoma.

A total of 672 surgically resected gastric carcinomas were reviewed, and fourteen cases(2.1%) of "gastric carcinoma with lymphoid stroma" were identified. The tumor was located mostly in cardia and body portion(86%). Thirteen patients one was lost to follow up were alive without recurrence of tumor. Grossly, this carcinoma was characterized by an expanding growth pattern or a multinodular pattern. Histologically, this carcinoma showed an irregular trabecular and alveolar arrangement and densely infiltrated lymphoid cells with lymph follicles. The tumor cell nests were widely separated by non-desmoplastic lymphoid stroma. On immunohistochemical study, T cells were evenly distributed throughout the tumor lesion with intimate contact with individual carcinoma cells, but B cells were mainly present within the germinal centers of lymph follicles. Thus, the organized immune response combined with cell mediated and humoral immunities against the carcinoma cells may be a defense mechanism of the host in this type of gastric carcinoma.

We present a series of 10 Patients(Seven men and three women with an average age of 53 years) who underwent decompressive craniectomy for treatment to massive brain swelling following acute cerebral infarction. Clinical signs of cerebral herniation(anisocoria or fixed and dilated pupil, and/or hemiplegia with decerebrate righidity) were present in all patients. Computed tomography and magnetic resonance imaging showed the mass effect by cerebral edema through midline shift. All patients were treated with an extensive craniectomy and duroplasty. Among them, one recovered without neurological deficit, three were moderately disabled but functionally dependent, three remained in a persistent vegetative state and three died within 9 days after surgery(good recovery=1, moderate disability=3, persistent vegetative state=3, death=3). The results suggest that decompressive craniectomy can be an useful lifesaving procedure for massive cerebral edema following widespread hemispheric infarction.

BACKGROUND: Blunted perception of dyspnea, which may be related to the increased mortality, has been demonstrated in patients with a history of near-fatal asthma and in the elderly. OBJECTIVE: The purpose of this study was to evaluate the relationship between the perception of dyspnea and the severity of asthma. METHOD: Baseline spirometry and Borg score change(A Borg score) during breathing through an inspiratory muscle trainer were measured in 27 consecutive asthma patients and 11 normal subjects. RESULTS: The baseline Borg score was negatively related to FEV1 A Borg score was significantly lower in asthmatics than in controls at high level of loads. A Borg score was lower in severe asthma than in mild asthma. A Borg score was positively related to the baseline FEV1. Seventy-five percent of severe asthma, 62.5% of moderate one, and 9.1% of mild one showed impaired dyspnea perception. Dyspnea perception was related to age(r, = -0.49, p<0.001). CONCLUSION: Three quarters of patients with severe asthma showed impaired dyspnea perception to inspiratory resistive load. Dyspnea perception was related to asthma severity and age.

Cloeortolone (9-a-chloro-6-a fluoro-11-B 21 digydroxy-16 methyl preganl,4-diene) is a newly synthesized corticonsteroid which has been found to have potent antinflammatory action and good tolerance through animal experiment. Several investigators reported its therapeutic affect in various dermatoses by topical application. The present was undertaken to evaluate the therapeutic effect of 0.1% clocortolone cream (Purantix-Sandoz) in patients with eczematous dermatoses and with psoriasis and to compare its effect with that of I% hydrocortisone. Eleven patients with contact dermatitis, 10 with psoriasis entered this study durtin the period of 6 months from January to june, 1977 at the Department of Dermatology, Seoul National University Hospital. All patients were instructed to apply 0.1% Clocortolone cream on one side of their lesion and 1%hydrocortisone cream on the opposite site for two weeks. After wo weeks' period of observation the status of the lesion was evaluated clinically and the tesults were as follows. 1. Ninety one percent of patiens with contact dermatitis, 70% of atopic dermatitis, 60% of nenrodermatitis, 67% of nummular eczema and 60% of psoriasis responded very effectively or moderately effectively. The therapeutic responses were generally similar to that of 1% hydrocortisone. 2. During the ovservation period, there was no systemic of local side effect of 0.1% Clocortolone cream.

In Korea, there are about 8 million motor vehicles and one-fourth of it is motorcycle. Last year Korean government report on the motor vehicle accidents claimed 12,781 cases of motorcycle accidents and it account for 5.1% of all of motor vehicle accidents occurred in Korea. But this is too broad analysis and lack of statical values. In general, most of people think motorcycle rider will suffer or die from head injuries sustained with motorcycle accident. Even though mandatory law on wearing helmet during motorcycle ride, but we see too many motorcycle riders not wearing helmet, especially in teenagers. The loss of young person by accident is great loss for family, society and economy of nation. No one will doubt the effectiveness of helmet on reduced incidence of head injuries. And multiple studies from United States of America have clearly demonstrated the benefit of helmets in motorcycle accidents. The following study was undertaken to determine the relationship between head injuries and helmet use in motorcycle accident, as well as analysis of general motorcycle accident.

PURPOSE: The purpose of this study was to evaluate the safety, feasibility and effectiveness of an endoluminally-placed bifurcated stent-graft (Vanguard) for the treatment of infrarenal abdominal aortic aneurysm (AAA). METHODS: Transluminal endovascular stent-graft placements were attempted in 29 patients (28 male, mean age 69+/-7 years) with AAAs involving the common iliac arteries from Aug. 1997 to Jan. 1999. Endovascular therapy was performed in the cardiac catheterization laboratory with epidural anesthesia. One side of the femoral artery was opened by surgical cutdown for the bifurcated stent-graft entry and the other side was punctured percutaneously for the straight stent-graft. Computed tomography and/or intraarterial angiography were performed during an average follow-up of 10 months (2-18 months). RESULTS: Primary success rate was 75.9% (22 of 29 patients) and the overall success rate was 79.3% with successful correction of one perigraft leak. Twenty patients (69.0%) had significant coronary artery disease. There were two technical failure cases, the one was tortuous iliac vessel with spasm, the other was disconnection of the stent-graft connecting portion. Complications related to procedure occurred in 13.8% of patients (4 of 29 patients) and two of these four patients had procedure-related mortality because of acute renal failure following contrast overdose and sepsis after operation. CONCLUSIONS: Endovascular treatment of infrarenal AAA with bifurcated stent-graft (Vanguard<0A397>) is effective, feasible and relatively safe. However, further investigation for the outcome, complication and long-term follow-up are needed.
