Ki-1 monoclonal antibody is a well known marker for Reed-Sternberg cells in Hodgkin's disease, but also occasionally reacts with activated lymphoid cells of either benign or malignant nature. Recently, Ki-1 antibody positive Non-Hodgkin's lymphoma, usually of large cell and/or polymorphous type, has been reported in the lymph nodes, skin, soft tissue, and stomach, but not in the bone. We report a case of multifocal primary bone lymphoma in a seven-year old body involving the left shoulder and right frontal bone, which proved to be a large cell, polymorphous lymphoma, helper T-cell type expressing Ki-1 antigen.

Emphysematous cystitis is a rare condition characterized by gas collection in the wall and lumen of the bladder. We experienced three cases of emphysematous cystiris. All patients were female; one was associated with a long term history of diabetes mellitus and another with urinary indwelling catheter. All of the cases were easily diagnosed on plain radiograph and CT scan, and were successfully treated with antibiotic therapy. In one of the cases, however, associated abscess due to perivesical extension of inflammation was treated by combined external drainage.

PURPOSE: Emphysematous pyelonephritis is a rare, life threatening infection of kidney and the pennephric space, characterized by the production of gas within the renal parenchyma. The aim of this study is to analyze the clinical and radiologic characteristics of emphysematous pyelonephritis. MATERIALS AND METHODS: We reviewed 7 cases of the emphysematous pyelonephritis. Six patients had plain abdominal radiographs, ultrasonograms and abdominal CT scans. Only one patient had plain radiograph and ultrasonogram. In 5 operated cases, CT findings were compared with surgical records. RESULTS: Plain radiographs showed characteristic diffuse mottling of gas in renal fossa. On sonogram, intrarenal gas was identified as echogenic loci with dirty shadows. CT scan showed inflammatory mass with gas and fluid levels in adjacent to the kidney. CT findings corresponded relatively wall with the surgical findings in regard to disease extent. CONCLUSION: lntrarenal gas in appropriate clinical setting is highly specific for emphysematous pyelonephritis. CT is the most sensitive method for demonstrating the disease extent as well as specific diagnosis.

Emphysematous cholecystitis is an uncommon condition which may mimic acute cholecystitis. But it differs from acute cholecystitis in its relatively greater frequency in men and diabetics and has graver prognosis. The condition is diagnosed by demonstration of air in lumen,wall of gallbladder and/or pericholecystic space using a variety of radiographic techniques: simple abdominal radiography, ultrasonography and CT scanning. One illustrative case is presented herein and the pertinent literature is reviewed.

We present 6 patients with systemic lupus erythematosus who had papulosquamous skin lesions. These skin lesions were consistent with the findings of subacute cutaenous lupus erythematosus(SCLE) clinically and histopathologically. The. distribution of the skin lesions were on the face, upper extremities and upper trunk in one group, and the upper and lower extremities in other group of these patients. After confirmation of the skin lesions as a type of SCLE, they were regressed with anti-malarial and/or systemic corticosteroids, within 2 months in all patients. For the better management of the patient with lupus erythematosus, understanding of clinically distinct LE-specific skin lesions, including the papulosquamous cuta-neous manifestation of SCLE, may be necessary.

Thirty-seven cases of cardiac neurosis were treated with propranolol (Inderal(R)) and following results were obtained. 1) Symptoms, such as palpitation, dyspnea, chest tightness and chest pain were disappeared or improved in all cases. 2) Heart rate reduced significantly after treatment from 99.8 per minutes to 74.8 per minutes. 3) Systolic blood pressure reduced significantly after treatment from 147.6 mmHg to 131.4 mmHg. but diastolic blood pressure were not reduced significantly. These results indicated that propranolol is recommendable medicine for improving cardiac symptoms and tachycardia in cardiac neurosis.

Carbon monoxide (CO) is a kind of freq uent toxic gas around our living lives, for common use of briquet as fuel, and its pathologic effect has been known due to mainly hypoxia and direct cytotoxicity in some part to almost all organs, especially to the brain and heart. Some authors have reported pathologic and anatomic changes of the acute of posioning, although in a few cases, that bilaterally symmetrical lesions of the globus pallidus or cerebral white matter regarded as typical. After using computed tomography (CT), those findings have been discovered more easily and acurately. Authors analysed CT find ings of 32 cases, who had a history of acute CO posioning and performed CT at Hanyang University Hospital from May 1979 to June 1983. The results were as follows: 1. Of all 32 cases with CT scan, low density lesions were demonstrated in 28 cases (88%) and others were hemorrhagic and calcified in 2(6%), respectively. 2. AII lesions were seen as bilaterally symmetrical, exce pt 2 cases of hemorrhage and 1 of low density . 3. Of all 28 cases of the low densities, 15 cases(53.6%) were located in the globus pallidus, 10(35.7%) in the cerebral white matter and 3( 1 0.7%) in both of them. 4. Of all 13 cases of the low density lesions in the cerebral wh ite matter, common locations were in the frontal and parietal lobes (65.6%), and more in frontal (40.6%). 5. Of all 13 cases of low density lesions in the cerebral white matter, cases of involving all of the lobes were found in only 4. 6. All of 2 cases of the cal c ified lesions were seen at both sides of the globus pallidus, symmetrically. 7. All of 2 cases of the hemorrhage were seen at thalamus, ventricles and head of caudate nucleus, and these locations were different from those of the low densities or calcifications.

This study was designed to assess the relative merits of percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) in multivessel coronary artery disease (MVCAD), particularly for Korean diabetics. Among 3,279 patients with MVCAD who were recommended for revascularization were enrolled from nine centers in Korea, 2,154 were selected after statistical adjustments for the disparities between two groups. Survival rates were not significantly different for three years between two groups. Among diabetic patients, the three-year mortality rate in PCI group was 1.9-fold higher than that of CABG group, although it was not statistically significant (PCI 19.8%, CABG 11.4%, p=0.14). The three-year mortality rate was similar between the two groups in non-diabetics (PCI 8.3%, CABG 10.0%, p=0.50). The 30-day rate of cerebrovascular event was higher in CABG group, for both diabetic (CABG 3.6%, PCI 0.0%, p<0.001) and non-diabetic patients (CABG 2.4%, PCI 0.0%, p<0.001). Short- and long-term revascularization rates were higher in PCI group than in CABG group. As a conclusion, this Korean registry demonstrates that PCI was associated with comparable survival rates and lower short-term morbidity, but a greater requirement for repeated revascularization compared with CABG in Korean diabetics.

BACKGROUND AND OBJECTIVE: Despite many multicenter trials on percutaneous coronary intervention (PCI), versus coronary artery bypass surgery (CABG), in multivessel coronary artery disease (MVCAD), the most appropriate treatment remains a matter of debate. Moreover, studies comparing the 2 strategies in eastern society are rare. The aim of this study was to assess the relative merits of PCI and CABG in MVCAD in the post-stent era. SUBJECTS AND METHODS: Patients, with MVCAD, indicated for revascularization were enrolled from 9 centers in Korea. Out of the 3,279 patients in the registry, 2102 (CABG 609 patients, PCI 1,493 patients) were selected for a comparison of their outcomes, after a statistical adjustments for the disparity for 6 independent risk factors, for the prognosis between the two groups. RESULTS: There was no significantly different in the 3 year survival rates between PCI and CABG groups. In the diabetic patients, the 3-year mortality rate in PCI group was 1.6-fold higher than in the CABG group, although it was not statistically significant (PCI 19.8%, CABG 12.5%, p=0.24). The incidence of cerebrovascular events (CVE) was higher in the CABG group. The thirty-day death rate, myocardial infarction or CVE were higher in the CABG group (PCI 1.3%, CABG 4.2%, p<0.001). Both the long and short-term revascularization rates were higher in PCI group compared to CABG group. CONCLUSION: Our Korean registry demonstrated a comparable survival rate between the PCI and CABG groups. A PCI was associated with a lower early morbidity, but with a greater need for repeated revascularization compared to a CABG.
