Authors retrospectively analyzed ultrasonographic findings of 12 cases of breast carcinomas which were proven pathologically at Yeungnam University Hospital from March 1992 to August 1992. Classically, breast carcinomas were described as irregular and lobulated hypoechoic solid masses with inhomogeneous internal echoes and frequent attenuation of the sound beam. And other additional ultrasonographic findings were echogenic rim, disruptions of superficial layer, microcalcification, skin thickening and so on. In our studies, not all of these findings of breast carcinomas were found in each case, but most of these findings were noted. However, several studies have demonstrated considerable overlap in the ultrasonographic appearance of benign lesions and carcinoma. Thus, accurate sonographic determination of the type of solid mass is not possible with current ultrasonographic imaging techniques and criteria. For more accurate diagnosis of breast lesions, sonographic and other imaging techniques are interpreted together.

Deep skin and soft tissue defects with exposed bone and tendon is difficult to treat, because skin graft rarely survives and flap surgery is sacrifice of donor site. Since "Stage I" membrane was developed by Yannas and Bruke in 1980, numerous kinds of artificial skin have been developed. The adaptability of "Terudermis", developed by the Terumo Co., as an artificial skin composed of sponge made of a fibrillar atelocollagen and a heat-denatured atelocollagen, was clinically evaluated on application to 13 cases presenting deep skin and soft tissue defect with exposed bones and tendons from October 1997 to march 1998. Terudermis has the advantage of allowing early incorporation of fibroblasts and capillaries into its collagen sponge due to very weak dehydrothermal cross-linking. Before Terudermis graft, several days of wet dressing and debridement were required to prepare healthy well-vascularized bed because Terudermis was weak on unsanitary wounds. After bed preparation, Terudermis was grafted like usual skin graft. Tie-over bolster dressing or compressive dressing was used case by case. The dressing was opened 2~3 days after Terudermis grafting. Wet dressing was done daily until the skin graft was done. Autologous skin graft was done 2-3 weeks after Terudermis graft. Our clinical results indicated that Terudermis was beneficial in treating 77% of our patients. Through the use of this new method, treatment of severe skin and soft tissue defects that are usually treated by musculocutaneous or other conventional skin flaps can be replaced by Terudermis as an new artificial dermis.

The goal of therapy in patients with traumatic carotid-cavernous fistulas is to occlude the fistula preferably while maintaining the carotid blood flow. Since the introduction of the concepts of detachable balloon technique to occlude arteriovenous fistulas, the technique has become the treatment of choice in the management of traumatic carotid-cavernous fistulas. The major symptoms of traumatic CCFs are (1) pulsating exophthalmos, (2) orbital and cephalic bruit and murmur, (3) headache, (4) chemosis, (5) extraocular palsies, and (6) visual failure. Traumatic CCFs are combined with multiple associated lesion. We tried the occlusion of fistulas using Goldvalve balloons in 8 consecutive cases of traumatic CCF and the result of our experience is reported. Transarterial approach with manually-tied latex balloons is tried in all cases and the fistulas was successfully occluded in all cases. In 5 cases, the internal carotid artery was preserved and the arterial lumen was occluded along with fistula opening in cases. In one case, surgical ligation was done because of symptoms recurred and incomplete occlusion of fistula. We experienced hemiparesis as a major complication in one case during occlusion tolerance test, which was remitted spontaneously. The results of Debrun balloon treatment were relatively excellent. We consider that the first choice of treatment of traumatic CCF is occlusion of the fistula by a detachable balloons.

The diagnosis of breast lymphoma is a prime consideration when a breast mass develops in a patient with a history of lymphoma either in lymphatic system or at other anatomic sites, with bilateral axillary lymph nodes enlargment. However, the radiologic findings of lymphoma in breast are known as non-specific. Breast lymphoma is extremely rare and it has never been reported in this country. We report two cases of breast lymphoma with mammographic and sonographic findings.

This study was performed to investigate the effect of Matrigel, a reconstituted basement membrane, on the expression of the anterior pituitary hormones in culture. Rat pituitary cells cultured for 6 days on Matrigel showed 3-dimensional, lobular structures with connecting cells while those on plastic showed flat, polygonal cells forming a monolayer. Western blot analysis showed that prolactin (PRL) content in the anterior pituitary cells was higher compared to those cultured on plastic. In comparison, TSH expression was not increased in cultures on Matrigel. The total cell number and the proportion of fibroblasts was decreased. These results suggested that Matrigel is a useful culture substrate for the enhanced expression of PRL but not for TSH. Further studies are needed in order to find a useful culture substrate for TSH cells.
