BACKGROUND: Interferon alpha-2a has already been shown to be effective in clinical use of virus-originated diseases such as hairy cell leukemia, condyloma acuminatum, and AIDS-related Kaposi's sarcoma. The use of recombinant alpha-interferon may allow common warts to be treated relatively atraumatically and with less incidence of recurrence. OBJECTIVE: We tried to determine the safety and effectiveness of intralesional injections of recombinant alpha-2a interferon in the treatment of patients with common warts. METHODS: A single wart on each patient was weekly injected with 0.75 to 1.5×10(5) IU/25mm2 of interferon for 8 weeks, and the response to treatment was followed up-to 6 months. RESULTS: Clearing of the treated wart at the end of treatment occurred in 5(71%) out of 7 patients and the rest showed no improvement. With evaluation for relapses up-to 6 months after treatment, warts relapsed in 2(40%) out of 5 patients. Therefore, 3(43%) out of 7 patients were completely free of warts 6 months after treatment. CONCLUSION: Intralesional recombinant interferon alpha-2a has a limited therapeutic effect, but may be considered as a therapeutic modality of recalcitrant verruca or when it can be anticipated that destructive techniques or blistering agents will not be tolerated.

Epilepsy surgery can be a safe, effective treatment for individuals with intractable partial epilepsy. There is increasing evidence that brain abnormalities in focal epilepsy are not restricted to a single area. The longstanding debate around the relationship between structural lesions and the epileptic zone remains unresolved. Patients with DNT (dysembryoplastic neuroepithelial tumor), which is an essentially benign tumor, can be cured by epilepsy surgery-oriented approach. Cortical dysplasia is frequently associated with DNT and seems to contribute to epileptogenic activity of DNT. Surgical treatment should be aimed at removal of the associated cortical dysplasia as well as DNT itself for ideal treatment of the disease. Simple lesionectomy of cavernous angioma would relieve seizures significantly, but not always. The concept of epilepsy surgery needs to be recruited in the treatment of cavernous angioma with seizures because diffusion of hemosiderin into the surrounding brain tissue and formation of cortical scars can make epileptogenic areas. Cortical dysplasia is a highly epileptogenic lesion constituting an important cause of medically intractable epilepsy and surgery is a treatment of choice in a selected group of patients. Identification and complete resection of the lesion and ictal onset zone are necessary to achieve a good surgical results. Intractable epilepsy accompanied by benign brain lesions can be treated surgically using the entire armamentarium of presurgical investigations. Deliberate resective procedures aimed at complete removal of dysplastic tissue and epiletogenically active areas on and around the lesion ensure excellent seizure control without permanent neurologic deficit.

BACKGROUND/AIMS: The endoscopic mucosal resection has now been adopted for a useful modality in both curative therapy and accurate diagnosis of early gastric cancer. A retrospective study was done to evaluate the indication and the limitation of endoscopic mucosal resection of early gastric cancer. METHODS: We studied 20 cases of early gastric cancer treated by endoscopic mucosal resection in Chungnam National University Hospital from November, 1995 to July, 1997. RESULTS: 1) The size affected the curability: 83. 3% of lesions less than 2 cm and 50. 0% of those larger than 2 cm were resected completely. 2) The depth of cancer invasion affected the curability: 87. 5% of lesion confined to mucosa were resected completely, while all of submucosal cancers were resected incompletely. 3) Among fourteen cases resected completely, three cases of lesions larger than 2 cm were residual cancer and two of those less than 2 cm were recurred locally. CONCLUSIONS: To be a curative therapy by endoscopic mucosal resection of early gastric cancer, we think that careful selection of the lesion, that is lesion less than 2cm and confined to mucosa, is necessary

PURPOSE: The ictal perfusion patterns of cerebellum and basal ganglia have not been systematically investigated in patients with temporal lobe epilepsy (TLE). Their ictal perfusion patterns were analyzed in relation with temporal lobe and frontal lobe hyperperfusion during TLE seizures using SPECT subtraction. MATERIALS AND METHODS: Thirty-three TLE patients had interictal and ictal SPECT, video-EEG monitoring, SPGR MRI, and SPECT subtraction with MRI co-registration. RESULTS: The vermian cerebellar hyperperfusion (CH) was observed in 26 patients (78.8%) and hemispheric CH in 25 (75.8%). Compared to the side of epileptogenic temporal lobe, there were seven ipsilateral hemispheric CH (28.0%), fifteen contralateral hemispheric CH (60.0%) and three bilateral hemispheric CH (12.0%). CH was more frequently observed in patients with additional frontal hyperperfusion (14/15, 93.3%) than in patients without frontal hyperperfusion (11/18, 61.1%). The basal ganglia hyperperfusion (BGH) was seen in 11 of the 15 patients with frontotemporal hyperperfusion (73.3%) and 11 of the 18 with temporal hyperperfusion only (61.1%). In 17 patients with unilateral BGH, contralateral CH to the BGH was observed in 14 (82.5%) and ipsilateral CH to BGH in 2 (11.8%) and bilateral CH in 1 (5.9%). CONCLUSION: The cerebellar hyperperfusion and basal ganglia hyperperfusion during seizures of TLE can be contralateral, ipsilateral or bilateral to the seizure focus. The presence of additional frontal or basal ganglia hyperperfusion was more frequently associated with contralateral hemispheric CH to their sides. However, temporal lobe hyperperfusion appears to be related with both ipsilateral and contralateral hemispheric CH.

BACKGROUND: The incidence of Cutaneous malignant tumors has increased recently and they have varied in their developing patterns according to social and environmental influences. However, we have little clinical data about the cutaneous malignant tumors in the Chonnam provinee. OBJECTIVE: Our purpose was to analyze the clinical characteristics of cutaneous malignant tumors observed in the Chonnam province and to compare them with the data previously reported in Korea. METHOD: We clinically analyzed 427 cases of cutaneous malignant tumors during a 10 year period betwecn January 1987 and Oetober 1996, at the Department of Dermatology, Chonnam Univemity Hospital in Kwangju. RESULTS: 1. The average armual incidence of cutaneous malignant tumors among the total number of outpatients was 1.00+/- 0.25%. The incidence tended to increase with time from 0.90+/-0.29% in the first 5 year-period to 1.15+/-0.09% in the late 5 year-period. The increasing rate was most pronmient in basal cell carcinoma. 2. The most common tumor in the 427 patients with malignant tumor was basal cell carcinoma (52.5%), followed by squamous cell carcinoma (19.9%), malignant melanoma (13.3%), metastatic carcinoma (3.7%), malignant lymphoma (2.3%). 3. The mean age of onset was 60.7+/-16.0 years old (male; 59.6+/-15.0, female; 61.9+/-17.1) in the in the group as a whole; 63.9 in BCC, 63.3 in SCC and 55.8 in malignant melanoma. The ratio of men to women was 1.14:l. 4. The most common site of a11 malignant tumors was the head and neck (64.6%), where 89.3% of BCC, 58.8% of SCC, and 15.8% of malignant melanoma developed. The next common site was the lower exlremities and feet (15.7%) followed by the trunk (7,7%), and upper extremities and hands (7.3%).

BACKGROUND: The detection of the phase reversal of somatosensory evoked potentials (SEP) has been well known to be a safe and reproducible method for defining the sensorimotor cortex. Brain stimulation (BS) has also been used to identify functional loci. The two tests, however have not to be compared in the cortical localization of the sensorimotor cortex yet. METHODS: We recorded the cortical potentials to median nerve stimulation from subdural grids which were in the frontoparietal areas of 12 epilepsy patients. After looking for phase reversals, we compared positive motor and sensory responses by brain stimulation from each electrode. In addition, the maximal amplitude areas of precentral positivity (max-P20) and postcentral negativity (max-N20) were analyzed, which were then compared with BS results. RESULTS: All patients showed phase reversals (average:4.7+1.61) on cortical SEP to median nerve stimulation. The electrodes before the phase reversal line had positive motor responses in 75% among electrodes with positive motor responses. The electrodes after the phase reversal line had positive sensory responses in 88.9% among electrodes with positive sensory responses. The maximal amplitude areas were recorded within a 2cm distance to the central sulcus. Max-P20's were located on the areas where BS showed a finger in 5 patients, hand in 3, forearm in 2, and tongue motor response in 2. Max-N20's were recorded on the areas where BS revealed a hand in 4 patients, forearm in 1, and undetected sensory responses in 7. CONCLUSIONS: These results suggest that SEP is different from BS in the functional localization of the perirolandic area. Thus, combined functional evaluation of the periolandic area by SEP as well as by BS is helpful in assessing sensorimotor functions.

We report a case of myelodysplastic syndrome (MDS) with unique histopathological findings in which numerous infiltrated neutrophils exhibited nuclear segmentation anomalies. In comparison with well-described neutrophilic dermatoses of myelodysplastic syndrome such as Sweets syndrome and pyoderma gangrenosum, this case took a rapid and aggressive clinical course. We suggest that a nuclear segmentation anomaly, pseudo Pelger-Hiiet anomaly, is likely to reflect acute transformation of MDS and can be a poor prognostic marker.

BACKGROUND: Intractable partial epilepsy is the most frequent manifestation in cortical dysplasia (CD). The surgical removal of the epileptogenic focus in CD is the main therapeutic option for achieving seizure control. However, it is dif-ficult to predict surgical outcome by current diagnostic methods. We investigated 35 subjects with intractable epilepsy due to CD, in order to know the relationship the extent of lesion in a magnetic resonance imaging (MRI), the epilepto-genic foci in invasive electroencephalography (IEEG), pathologic grading, and surgical outcome. METHODS: We reviewed clinical findings (the seizure history, MRI), IEEG findings (interictal and ictal EEG), pathologic findings and surgical outcomes retrospectively and compared them. All the patients ranged in age from 2 to 45 years (mean: 21.8+10.8years). The time of their seizure onset ranged from 6 months to 31 years (mean:9.4+6.6years). The postopera-tive follow-up period ranged from 7 to 45months (mean:26+14months). RESULTS: Regarding MRI findings, the lesions were focal (within one lobe) in 10, diffuse (more than one lobe) in 7, and no abnormalities in 18 subjects. The ictal onset zones of ictal IEEG had one focus in 18, two in 7, three in 7, and four in 3 subjects. The area of focus was focal in 15, regional in 14, lobar in 4, and in diffuse areas in 2 subjects. Pathologic grading revealed mild in 18, moderate in 5, and severe changes in 13 subjects. Their surgical outcomes were: Engel's class I in 20, class II in 7, class III in 6, and class IV in 2 subjects. The relationships among clinical features, IEEG, regarding pathology and surgical outcomes, revealed that severe pathologic grading had a significant correlation with earlier ictal onset zones (p=0.003), and diffuse MRI lesions. Diffuse ictal onset zones had poor surgical outcomes (p<0.010). CONCLUSIONS: Cortical dysplasia may have a diverse pattern of epileptogenic foci in MRI and IEEG. The earlier the seizure onset is, the severe pathologic grading becomes. When the lesions in MRI as well as the ictal onet zones in IEEG were diffuse, the surgical outcome was poor.

Eosinophilia-myalgia syndrome(EMS) is a systemic illness that occurred as an epidemic by ingestion of over-the counter L-tryptophan preparation in the United States in October 1989. We report a Korean case of EMS not associated with the ingestion of either L-tryptophan or other nutritional supplements such as lysine and niacin.
