Bile duct necrosis and liver abscess are rare complications after transcatheter hepatic arterial embolization (THAE) of hepatocellular carcinoma. Authors report bile duct necrosis and liver abscess occurred in 2 cases as a complication of THAE of hepatocellular carcinoma. In these two patients, lipiodol emulsion mixed with adriamycin and mitomycin was used more than three times as chemoembolic materials.

We report. herein a case of pruritic urticatial papules and plaques of pregnancy in a Z8-year-old primigravida. She had the urticarial papules and plaques on the abdomen and thighs, which developed at 30th week of pregnancy. She was treated with topical fluorinated steroid and chlorpheniramine, 6mg/ day. The itching sensation was relieved within 24 hours after the therapy and the skin lesions resolved after delivery.

Tumors involving the proximal humerus confront the surgeon with the problem of both eradicating the osseous lesions and restoring shoulder joint function. This problem is magnified because of the biomechanical complexity of the shoulder, its anatomic configuration, and its inherent lack of stabillity. With the increased interest in limb-sparing resection for lesions in the area, efforts are being made to improve the reconstructive techniques. These include leaving a flail shoulder, an being made to improve the reconstructive techniques. These include leaving a flail shoulder, an arthrodesis using intercalery graft between the scapula and the remaining humerus, or if the glenoid is preserved, an arthroplasy. From January 1984 to December 1993, 23 patients with a malignant or locally aggressive bone tumor in the proximal humerus were treated by limb-sparing surgery in Seoul National University Hospital. Histologic diagnosis included osteosarcoma(6), chondrosarcoma(2), Ewing's sarcoma(1), metastatic bone tumor(11), and recurred giant cell tumor(3). Options for reconstruction following limb-sparing resection in our cases were 10 prosthetic arthroplasties, 3 arthrodeses with an living fibula graft, and 10 arthroplasties with intramedullary nailing and cementization. We performed a retrospective analysis in view of tumor eradication and performance status with modified functional evaluation system of Musculoskeletal tumor Society. In 7 cases(74%), good or fair performance status was acquired with average 3.6 years follow-up(6 months-11 years). Each option for reconstruction resulted in relatively good outcome but rather better result was acquired in giant cell tumor and chondrosarcoma. Estimated survival rates by Kaplan-Meier's method, 5 year survival rate was 81% in primary malignant bone tumors(12), 76% in stage Ⅱ B malignancies(5) with 4 years and 4 months follow-up. There was no regional recurrence in primary malignant bone tumors but there were three cases in which distant pulmonary metastases were found in follow-up. Complicationss were one soft tissue infection, two nonunions in arthrodesis with a living fibula graft and one dislodgement of prosthesis in prosthetic arthroplasty. In summary, each option for limb-sparing surgery in malignant bone tumor of proximal humerus might result in rather satisfactory outcome in performance and survival rate when effective preoperative and postoperative chemotherapy were performed in adequately selected cases.

Afferent loop syndrome(ALS) is caused by obstruction of the afferent loop after subtotal gastrectomy with Billroth II gastrojejunostomy. Prompt diagnosis of ALS is important as perforation of the loop occurs. The aim of this study is to ascertain the value of sonography and CT to diagnose ALS. We describe the radiologic findings in ten patients with ALS. The causes of ALS, established at surgery, included cancer recurrence (n=4), internal hernia(n=4), marginal ulcer (n=1), and development of cancer at the anastomosis site(n=1). Abdominal X-ray and sonography were performed in all cases, upper GI series in five cases and computed tomography in two cases. The dilated afferent loop was detected in only two cases out of ten patients in retrospective review of abdominal X-ray. ALS with recurrence of cancer was diagnosed in three cases by upper GI series. Of the cases that had sonography, the afferent loop was seen in the upper abdomen crossing transversely over the midline in all ten patients. The causes of ALS were predicted on the basis of the sonograms in three of the five cancer patients. In two cases of computed tomography, the dilated afferent loop and recurrent cancer at the remnant stomach were seen. Our experience suggests that the diagnosis of afferent loop syndrome can be made on the basis of the typical anatomic location and shape of the dilated bowel loop in both sonography and computed tomography.

The most common causes of conjugated hyperbilirubinemia after the first or second week of life are neonatal hepatitis and biliary atresia. Since these entities represent variable expressions of same pathologic process and have similar clinical, biochemical, and histologic features, differential diagnosis is extremely difficult. We prospectively studied 28 jaundiced infants by sonography and hepatobiliary scintigraphy. Final diagnoses included 12 biliary atresia and 16 neonatal hepatitis. Visualization of a normal-sized common bile duct or gallbladder was compatible with the diagnosis of neonatal hepatitis. Non-visualized or atrophic gallbladder no sonography coupled with non-visualization of bowel activity on scintigraphy was highly suggestive of biliary atresia. We believe that sonography plays valuable role in the initial evaluation of the infants with persistent neonatal jaundice. The combined use of sonography and hepatobiliary scintigraphy provides the most valuable in formation in suspected biliary atresia for prompt surgical treatment.
