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.

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.

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.

BACKGROUND: The real incidence of atherosclerotic lesions in carotid and peripheral arteries in coronary artery disease patients is not well known in Korea. The aim of this study was to prospectively evaluate the prevalence of atherosclerotic involvement of the coronary, carotid, and peripheral arteries in each arterial disease patients. This study was also designed to evaluate the risk factors, the clinical characteristics of associated carotid artery stenosis in patients with coronary artery disease, and associated peripheral vascular disease in patients with coronary artery disease. METHODS: Between June 1996 and March 1998, 475 patients (369 males, 106 females, mean age 60+/-10 years) were studied. Three hundred and seventy-three patients who presented with ischemic symptoms were enrolled in the coronary artery disease group, 81 patients were enrolled in the peripheral vascular disease group due to presenting claudications, and 21 patients were enrolled in the carotid stenosis group due to presenting cerebrovascular symptoms. Coronary angiography was done by the routine method. Carotid angiography was performed at the aortic arch by the digital subtraction angiography method. Peripheral vascular angiography was taken from the suprarenal abdominal aorta to both femoral arteries. RESULTS: 1) Risk factors for coronary stenosis, peripheral vascular disease, and carotid stenosis: The risk factors were not different between coronary stenosis, peripheral vascular disease, and carotid stenosis groups, but smoking was more frequent among patients with peripheral vascular disease than in patients with coronary stenosis (p-value=0.001). 2) Coronary artery stenosis and carotid artery stenosis: The mean age of coronary artery patients with carotid stenosis was significantly older (p-value=0.006) than for patients without carotid stenosis. The prevalence of peripheral vascular disease was more common in patients with carotid stenosis than in patients without carotid stenosis. 3) Coronary artery stenosis and peripheral vascular disease: Carotid stenosis was more common inpatients with peripheral vascular disease than in patients without peripheral vascular disease in the coronary stenosis group. 4) Prevalence of coronary, carotid, and peripheral artery disease: In patients with coronary stenosis, the prevalence of carotid stenosis was 13.9% and that of peripheral vascular disease was 29.2%. In patients with peripheral artery stenosis, the prevalence of coronary stenosis was 45.7% and that of carotid artery disease was 33.3%. In patients with carotid stenosis, the prevalence of coronary stenosis was 81.0% and that of peripheral vascular disease was 52.4%. CONCLUSION: Carotid artery disease and peripheral vascular disease developed concurrently with coronary artery disease in a significant proportion of patients. Therefore, routine angiography of peripheral and carotid arteries in patients with coronary artery disease is considered, especially in old age.

The 56-kilodalton protein genes of Orientia tsutsugamushi TA678, TA686, TA716, TA763 strains were amplified by PCR. The amplified products were sequenced and cloned into pIH821 vector. The recombinant proteins were expressed in Escherichia coli as fusion proteins with maltose binding protein. The recombinant proteins were purified and used for the sensitization of sheep RBCs and the reactivity of the recombinant 56-kDa proteins of Orientia tsutsugamushi TA 678, TA686, TA716 strains were analyzed with 40 sera from scrub typhus patients in Korea, 40 sera from scrub typhus in Thailand, Malaysia and Philippines. The 56-kDa protein coding DNA sequence of Orientia tsutsugamushi TA678, TA686, TA716 show 70 to 88% homology with other known strains and four variable regions are also observed. 39 of 40 sera from scrub typhus patients in Korea showed the strongest reactivity to the recombinant protein of Boryong strain and one sera showed the strongest reactivity to the recombinant protein of Gilliam strain. 14 of 40 sera from patients in Thailand, Malaysia and Philippines showed the strongest reactivity to the recombinant protein of TA686 strain and 12 sera showed the strongest reactivity to the recombinant protein of TA716 strain. No serum from patients in Thailand, Malaysia and Philippines showed the strongest reactivity to the recombinant protein of Boryong strain.

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.
