Alveolar echinococcosis (AE) caused by infection with E. multilocularis metacestode, represents one of the most fatal helminthic diseases. AE is principally manifested with infiltrative, proliferating hepatic mass, resembling primary hepatocellular carcinoma. Sometimes metastatic lesions are found in nearby or remote tissue. AE diagnosis largely depends on imaging studies, but atypical findings of imaging features frequently require differential diagnosis from other hepatic lesions. Serological tests may provide further evidence, while obtaining reliable AE materials is not easy. In this study, alternative antigens, specific to AE were identified by analyzing E. granulosus protoscolex proteins. An immunoblot analysis of E. granulosus protoscolex showed that a group of low-molecular-weight proteins in the range from 14 kDa to 16 kDa exhibited a sensitive and specific immune response to AE patient sera. Partial purification and proteomic analysis indicated that this protein group contained myosin, tubulin polymerization promoting protein, fatty-acid binding protein, uncharacterized DM9, heat shock protein 90 cochaperone tebp P-23, and antigen S. When the serological applicability of recombinant forms of these proteins was assessed using enzyme-linked immunosorbent assay, DM9 protein (rEgDM9) showed 90.1% sensitivity (73/81 sera tested) and 94.5% specificity (172/181 sera tested), respectively. rEgDM9 showed weak cross-reactions with patient sera from the transitional and chronic stages of cystic echinococcosis (3 to 5 stages). rEgDM9 would serve as a useful alternative antigen for serodiagnosis of both early- and advanced-stage AE cases.

The coronary arteries of young individuals are histologically studied. Fourteen cases in pediatric age group and three adult hearts were used. No case had clinical and pathological evidences of heart disease. Inner circumference, thickness of tunicae intima, media and adventitia were measured at eight different sites of coronary arteries. The thickness of tunica media was used as a standard scale of cardiac growth, and the heart weight, body weight, height and age were compared with the medial thickness. The morphological changes were assessed in five groups by the heart weights. Group I ( less than 10 gm) showed single endothelial lining with cytoplasmic vacuolization or endothelial denudation. Group II (more than 10 but less than 20 gm) consisted of full term babies and showed first stigma of focal intimal thickening and intimal collagen fibers. Diffuse intimal thickening more than 1/1 of medial thickness was first seen in a case with 46 gm of heart weight. Elastic fiber was not seen in internal elastic laminae of groups I and II. Fragmentation of internal elastic lamina and smooth muscle proliferation as a form of musculoelastic layer were the major findings of intimal thickening in childhood and no case showed complicated atherosclerotic lesions.

The ligamentum nuchae is a midline structure extending from the occiput to the spinous process of the 7th cervical vertebra. Radio-opaque formations in the soft tissues behind the processes of the cervical spine has been known to radiologists since Barsony's description in 1929. It may actually be a normal sesamoid, or it may have developed as a result of previous trauma. But this remains hypothetical in that histological endochondral ossification sequence has not yet been demonstrated. These are generally asymptomatic and of clinical significance only in so far as they may be confused with fracture or tumors. Two patients who had clinical symptoms with or without previous trauma visited and they were relieved of their clinical symptoms by surgical excision. Then, we report on two unusual cases which were symptomatic.

PSTT has been established as a separate entity distinct from choriocarcinoma since 1983, because of its different morphological features, biologic behavior and response to chemotherapy. Most cases of PSTT have indolent clinical courses, but there have been several reports showing malignant behavior resulted in death of the patient. We report a case of PSTT showing vaginal metastatis. In biopsy specimen, it was difficult to make differential diagnosis from squamous cell carcinoma of uterine cervix due to uniform and mononuclear cytologic characteristics. Immunohistochemical stains for hPL and hCG were not typical for either PSTT or choriocarcinoma. We suggest that poorly differentiated PSTT may synthesize the lesser amount of hPL than typical PSTT and it may behave more aggressively.

Hereditary hemorrhagic telangiectasia (HHT) or Osler-Weber-Rendu disease is an autosomal dominant disorder characterized by repeated episodes of bleeding. Multiple telangiectases consisting of thin-walled, dilated vascular channels with arteriovenous communication may involve, for example, mucocutaneous tissue, the gastrointestinal tract, and the liver, lung, and brain. We report the imaging findings of two cases of HHT involving arteriovenous malformation of both the lungs and liver, a rare condition. Chest radiography revealed a round mass, while helical CT showed a feeding artery and draining vein with arteriovenous malformation in the lung. Color Doppler sonography revealed an enlarged and tortuous hepatic artery with high systolic velocity. CT demonstrated an enlarged hepatic artery, arteriovenous shunt, and early draining hepatic vein in the liver. Celiac angiography showed arteriovenous malformation.

8.Complications on Strabismus Surgery.
Journal of the Korean Ophthalmological Society 1988;29(4):619-623
The authors analyzed clinically the complications of the patients who had strabismus surgery at the Department of Ophthalmology, Pusan National University from January 1984 to June 1987. The results were as follows: 1. The complications were 50 cases(8.3%) in 599 patients who had strabismus surgery. 2. The complications were as follows: Prolapse of Tenon's capsule(10 cases), chronie suture granuloma(4 cases), dellen(3 cases), conjunctival cyst(2 cases), suture abscess(1 case), lid fissure anomaly(4 cases), ptosis(1 case), overaction(20 cases), diplopia(2 cases), others(3 cases). 3. The incidence of chronic suture granuloma were 0.7% by use of 6-0 vicryl suture. 4. Prolapse of Tenon's capsule and chronic suture granuloma were much debveloped in resection procedure of non limbal conjunctival approach, but dellen in limbal approach. 5. The incidence of overcorrection were 3.3%, and not different between exotropia and esotropia, and increased as much as the increase of the amount of preoperative deviated angle. 6. No anterior segment ischemia occured in 8 cases of Jensen operation in patient with 6th nerve palsy.

PURPOSE: We analyzed the clinical outcome of osteosarcoma developed in distal radius and the effect of delayed treatment on prognosis. MATERIALS AND METHODS: Twelve patients with distal radius osteosarcoma were analysed. We categorized patients into two groups of standard treatment or non-standard treatment. The patients of standard treatment group are all stage IIB and non-standard treatment group includes five stage IIB and one stage III. RESULTS: Five-year overall survival and disease-free survival rates of standard treatment group were 100% and 83%. Five-year overall survival rate of non-standard treatment group was 44%. Between two group, there are differences in age, tumor size, surgery type, symptom duration. CONCLUSION: Distal radius osteosarcoma have good prognosis than other extremity osteosarcoma. Survival rate of non-standard treatment group were lower than standard treatment group. Although the prognosis of non standard treatment group is poorer, the duration till death was longer than that of other sites with similar condition. Further multi-institutional study should be needed.

Male Breast cancer is an uncommon disease with an incidence of I per cent of all breast cancers. Male breast cancer usually appears as a small mass with well-defined contour which is eccentrically located in relation to the nipple on mammogram. We report a case of breast cancer in a 51-year-old man with mammographic appearance of large hyperdense mass with nipple inversion and axillary lymphadenopathy, gray-scale sonographic finding of homogeneous solid mass and mu Itiple tumor vessels with in the mass on color Doppler ultrasound.
