This study was intended to investigate the pre-and postoperative profile of seizures in the patients with cerebral arteriovenous malformatins(AVM's), and to evaluate various preoperative factors to predict the postoperative occurrence of seizures. The patients consisted of 46 consecutive cases with supratentorial AVM's operated on from May 1987 to May 1993. Their mean follow-up duration was 40 months. The pre- and postoperative seizure profiles were similar to each other. The overall incidence of patients experiencing seizure were 50% preoperatively and 52% postoperatively, and the incidence of intractable seizure was 15%, which was the same in both the pre-and postoperatively period. The presence of preoperative seizure and large size of AVM were significant indicators of high incidence of postoperative seizures(P<0.05), while other factors such as preoperative intracerebral hemorrhage or embolization showed no significant influence on the occurrence of postoperative seizures. About 70% of the patients with preoperative seizures also had postoperative seizures, while those without preoperative seizures developed new ones only in 35% of the cases postoperatively. The mean size of the AVM's in the group, with postoperative seizures was larger than that of the group without postoperative seizures(4.56 vs. 3.02 cm). Regarding postoperative intractable seizures, 57% of the group with preoperative intractable seizures remained intractable postoperatively and groups with preoperatively controlled and groups without seizures demonstrated postoperative intractablity only in 13% and 4% respectively. In conclusion, surgery of AVM's did not change the overall incidence of seizures, both controlled and intractable, and patients with preoperative and large sized AVM's and significantly higher possibility of postoperative seizures. Patients with preoperative intractable seizures resulted in control of seizures in 43% after removal of AVM, while 57% remained intractable. Extirpation of epileptic focl, after localization with preoperative study, seems to be needed to improve the outcome of the postoperative seizures.

BACKGROUND: To evaluate the changing pattern of liver abscess treatment, we did a retrospective analysis of 80 patients with liver abscess, treated surgically and medically at the Department of Surgery and Internal Medicine, Wonkwang University Hospital from January 1985 to December, 1995. RESULTS: Among 80cases of liver abscess, 59 cases(76%) were pyogenic abscess and 21 cases(24%) were amebic abscess. The liver abscess was more commonly located in the right lobe. In the 59cases of pyogenic liver abscess, etiologic factors were biliary stones with cholangitis(19 cases), cholecystitis(6 cases), hepatobiliary cancer(4 cases), diabetes mellitus(3 cases). All 21 cases of amebic abscess were treated with percutaneous catheter drainage and metronidazole administration; 20 cases were treated successfully and 1 case died of sepsis. Among the 59 cases of pyogenic liver abscess, 38 cases were treated with percutaneous catheter drainage; 30 cases were successful, but 8 cases were not. Operations were performed in 21 cases because of underlying intraabdominal conditions requiring surgical correction( 19cases) and panperitonitis due to rupture of liver abscess(2cases). CONCLUSION: In the treatment of amebic abscss, percutaneous catheter drainage and metanidazole adminstration should be considered first. Percutaneous catheter drainage and antibiotic treatment tend to increase more than surgical treatment in the pyogenic liver abscess therapy. The liver abscess is no more surgical indication, unless it is associated with underlying intraabdominal conditions requiring surgical correction and panperitonitis due to rupture of liver abscess.

Merkel cell carcinoma (MCC) is an unusual primary cutaneous tumor, occasionally found con-current with other malignancies. A case of MCC with coexisting squamous cell carcinoma (SCC) was studied histologically, immunohistochemically and ultrastructurally. The MCC and SCC occured at the same site, but each preserved its identity and transition between the two was not identified.

Phakomatosis pigmentovascularis was first described in 1947 as a distinctive association of cutaneous hemangioma and pigmentary nevi by Ota et al. We describe a 7-year-old boy who, since birth, had three kinds of discolored patches over the various parts of the body: blue spots (dermal melanocytic nevi), reticulated reddish patches (nevus flammeus), and hypopigmented macules (nevus anemicus). No systemic disease was found.
