A case of 39-year-old male with keratosis palmoplantaria nummularis was reported. The skin lesions were characterized by the presence of painful focal keratoses on the plantar pressure points. Biopsy of a keratotic plantar lesion revealed excessive hyperkerstosis, hypergranulosis, focal hypogranulosis, and acanthosis in the epidermis. We could observe aymptomatic relief of this patient who was treated with mixture of corticosteroid, 25% urea and 2.5% salicylic acid.

Purpose: The results of a more than 10-year follow-up after total hip arthroplasties with circumferential and proximal porous-coated femoral stems were evaluated. Materials and Methods: Seventy-six patients (80 hips), who were operated on between Aug. 1991 and July 1994, were followed for more than 10 years after primary total hip arthroplasties using Multilock stems. The mean age at the time of the operations was 47.3 years old and the mean duration of follow-up was 12.3 years. The clinical results and radiological findings were evaluated. Results: The mean Harris hip scores improved from 54.7 points to 88.5 points at the time of the 10-year follow up. On the last follow-up radiograph, endosteal bone formation was observed in 70 hips (90%) and all femoral stems were biologically stable. Femoral osteolysis, which was linear in Gruen zone I and VII and mostly restricted to the proximal zones, was observed in 67 hips (84%), and no hip had distal osteolysis in the femur. There was no loosening, migration, or revisions of the stems. Conclusion: Total hip arthroplasties using circumferential and proximal porous coated Multilock femoral stems demonstrated stable osseous fixation and no distal osteolysis for a minimum 10-year follow-up; therefore, all stems were reported to have satisfactory outcomes. With improvement of cup design and liner wear, circumferential and proximal porous coating designs of femoral stems can be an alternative answer to mechanical failure due to aseptic loosening.

BACKGROUND AND OBJECTIVES: Though the surgical intervention of subclavian artery stenosis has been effective, its high morbidity and mortality have limited its clinical application. In 1980 percutaneous balloon angioplasty of stenotic artery was introduced as a substitute for surgical intervention and subsequent reports have supported its efficacy noting that it is more effective when combined with stent. The purpose of this study was to assess the feasibility, safety, and efficacy of percutaneous intervention as an alternative or primary therapy for symptomatic subclavian artery stenosis. METHODS: Between September 1993 and October 1998, 17 lesions in 16 patients of symptomatic subclavian artery stenosis were enrolled as candidates for nonsurgical intervention. We performed percutaneous balloon angioplasty with stenting to the subclavian artery stenosis and evaluated the early results. RESULTS: 1)The patients had a mean age of 55+/-14 years and 13 of 16 patients were male. 2)Subclavian artery stenting was successful in 94% (16/17) of the lesion without significant complications. The cause of failure was suboptimal result after deployment of stent. 3)The types of stents deployed were Strecker stents in 4, Palmaz stents in 8, Wall stents in 3 and Jo stents in 2 cases. 4)The peak and mean pressure gradient reduced from 58.5+/-17.0 to 8.5+/-7.4 and 31.4+/-13.0 to 4.7+/-5.5 mmHg respectively (p<0.01) and the degree of luminal stenosis decreased from 92.5+/-8.5% to 10.0+/-14.3%. (p<0.01) CONCLUSION: Subclavian artery stenosis can be managed safely and effectively through percutaneous balloon angioplasty with stenting, with an excellent technical success rate and less morbidity and mortality particularly in patients coexisting other vascular and systemic diseases. However, the long-term patency and clinical effects should be warranted.

We report a cace of 69-year-old man who developed massive pulmonary hemorrhage and subsuquent adult respiratory distress syndrome following intravenous urokinase for acute myocardial infarction. Pulmonary hemorrhage is a rare but a potentially life-threatening complication after thrombolytic therapy and should be considered in the differential diagnosis of pulmonary infiltrates of falling hemoglobin after thrombolytic therapy for acute myocardial infarction with no obvious site of bleeding.

PURPOSE: To verify the value of CT in the diagnosis of cirrhosis, CRL ratio was measured in 225 Koreans who had and evidence of cirrhosis both clinically and radiologically. MATERIALS AND METHODS: The mean value of CRL ratio was 0.68+/-0.21 which was significant difterent from the published value of normal person(0.45+/-0.07). The difference of CRL ratio between men and women and that among different age groups were found to be not statistically signficant. RESULTS: CRL ratio of virus- related group(N:149) was 0.64+/-0.18, whereas that of virus-nonrelated group (N=76) was 0.76+/-0.23. There was a statistically significant difference of CRL ratio between virus-related group and virus-nonrelated group. CRL ratio of hepatoma-related group(N:113) was 0.71+/-0.22 whereas that of heparoma-nonrelated group(N:112) was 0.66+/-0.19. There was no statistically significant difference of CRL ratio between hepatoma-related group and hepatoma-nonrelated group. CONCLUSION: Measurement of CRL ratio by CT is a useful method in assessing cirrhosis of the liver.

PURPOSE: To assess the effectiveness and clinical usefulness of prostate biopsy by automated gun biopsy device under the transrectal ultrasonographic guidance, authors analysed the result of biopsy and the patients status after biopsy procedure. METHODS AND MATERIALS: The subjects consisted of 24 patients with prostatic disease. Biopsy instrument was an automated gun biopsy device loaded with an 18 gauze biopsy needle. All the patients were admitted to the hospital. No analgesics was given. All the procedure was performed with the patient in left lateral decubitus. Biopsy was performed at 2-4 different points of the prostate in 22 cases, but recently, six different points were targeted in two patients. RESULTS: Biopsy specimens were sufficient in 21 cases but insufficient in three cases. Histologic examination of biopsy specimens showed that 13 cases were nodular hyperplasia, eight cases were cancerous and three cases were inflammation. There was no clinically significant complication. There was mild to moderate degree of pain in all patients. CONCLUSION: Tansrectal biopsy of the prostate with an automated gun biopsy device under ultrasonographic guidance is considered relatively easy, handy and useful procedure in patients with prostatic disease. The procedure may be performed on the outpatient basis.
