2.Efficacy of Gabapentin Therapy in Refractory Seizure.
Journal of the Korean Child Neurology Society 1998;5(2):251-257
BACKGROUND: It is known that 20% of childhood epilepsy is refractory to anticonvulsants therapy, Recently, a few new anticonvulsants has been introduced. One of these, gabapentin is known to effective in such refractory cases. This study has been done to estimate the effectiveness of gabapentin in refractory childhood as well as adult epilepsies. SUBJECTS AND METHODS: 43 patients(male 25, female 18) has been selected among refractory epilepsies during the period of March, 1981 to Feb, 1996 diagnosed and treated at pediatric neurologic clinic School of Medicine, Yonsei University Those were already treated with various anticonvulsants and gabapentin was added to previous medication, and effectiveness of seizure frequency and the degree has been investigated over more than 3 month period as well as the side effect. RESULTS: 30 patients out of 43, showed seizure free or decreased frequency of seizure, those patients whose the seizure frequency was decreased over 50% was 11 cases, partial seizure 10 cases, generalized seizure 1 cases. 15 case out of 43 showed no changes or increased frequencies of seizure in 4 out of 27 in partial epilepsies, 1 out of 16 in generalized seizure, and 6 cases out of 43 manifested side effects such as behaviour change, abdominal pain and headache. CONCLUSION: Gabapentin was effective by add on therapy in refractory epilepsies and reducing the frequency of seizure over 50% was 25.6%. Most of these patients was partial seizure. We concluded that gabapentin as add on therapy is effective at least in 1/4 cases of refractory partial seizures.

Various dermatological complications have been reported following the BCG vaccination although this vaccination has been recommended to all healthy infants in our country. A 4-months-old boy, who had a BCG vaccination three weeks after birth, developed erythematous papules and pustules on the whole body, especially on the face and upper extremities. Two erythematous subcutaneous soft nodules were also noted on the left side of the neck. A biopsy specimen from the right forearm revealed caseous necrosis surrounded by a granulomatous inflammation consisting of epithelioid cells and lymphocytes. It was centered along the axis of the damaged pilosebaceous follicle. No acid-fast bacilli could be demonstrated by AFB stain. A marked improvement of his skin eruptions was observed after anti-tuberculosis medication. However, nod-ules in the cervical area perforated spontaneously and healed leaving scars several months after the cutaneous eruptions subsided. The clinical and histologic findings and a good response to anti-tuberculous therapy support the diagnosis of papular tuberculid and suppurative lymphadenitis after BCG vaccination.

To investigate MR artifacts induced by metallic implants, scans were obtained using both the ferromagnetic Drake lip and the non ferromagnetic Yasargil clip. Scan were taken through the area of clips using geometrical phantom. The MRI was performed by spin echo technique and gradient echo technique on both 2.0T and 0.5T MR unit. The luthors evaluated the nature and differences of artifacts in each sequence and parameter. Artifacts induced by both lips were noted in the direction of frequency encoding gradient, and consisted of region of signal loss abutted in one side by survilinear region of bright signal. Geometric distortion of image was marked in the Drake clip, out was minimal in the Yasargil clip under both 2.0T and 0.5T. Artifacts were more pronounced in the gradient echo technique than those of the spin echo technique on both 2.0T and 0.5T. Although there were no differences n the nature of artifacts induced by the Drake clip among each parameter in the spin echo technique under 2.0T, artifacts were slightly more pronounced on T2 weighted image under the 0.5T field, but no differences were found in the nature of artifacts induced by the Yasargil clip in the spin echo technique under, both the 2.0T and 0.5T fields. Marked artifacts were induced through the small area of the Drake clip which were included in the scan plane, but induced artifacts were small when a small area of the Yasargil clip was included in the scan plane. It seemed likely hat artifacts were slightly more pronounced in the 2.0T than the 0.5T field in both clips, but objective evaluation of the difference was difficult, In conclusion, these results can be an essential basis for the interpretation of MR images or patents with metallic inplants.

In general, the three major oral functions of edentulous patients-mastication, phonation, esthetics-can be rehabilitated by the complete dentures, and both the resin based complete denture and the metal based complete denture are commonly used by many clinicians today. For the sake of many advantages such as the excellent thermal conductivity, low volumetric change, high strength, low risk of fracture and the better patient's adaptation, the metal based complete dentures are indicated to the several cases. But, there are common failures of these type of dentures mainly by the fracture or the debonding between the resin structures and the metal frameworks which is caused by the discrepancies by the discrepancies of the flexural strength and the coefficient of thermal expansion. This is aggravated by the water contamination of the interface when exposed to the oral environment and results in the failure of complete denture treatment. So, the purpose of this study is to compare the bond strength and the fracture patterns of the gold alloy based and the Co-Cr alloy based complete dentures using the PMMA resins and the 4-META adhesive resins. The results of this study were as follows. 1. Both to th PMMA resin and the 4-META resin, the flexural bond strength of gold alloy is lower than that of Co-Cr alloy(p<0.05). 2. To the Co-Cr alloy, the bond strength of the 4-META resin is significantly higher tan that of PMMA resin(P<0.05). 3. The flexural strength of the group with the mechanical retention form is significantly higher than that of the group without retention form(P<0.05). 4. Comparing with the other groups, the fracture patterns of the group 3 are quite different from the group 1, 2, 5.

PURPOSE: To evaluate the radiological patterns of vascular invasion in peripheral cholangiocarcinomas. MATERIALS AND METHODS: Hepatic arteriography and portography in 20 cases with cholangiocarcinoma including 12 cases with anglographic CT were retrospectively analized. RESULTS: The arteriography showed no arterioportal shunt, hypertrophy of tumor vessel, or tumor staining extending to central portion of the mass in all cases. However, doughnut shaped peripheral tumor staining was seen until late hepatogram phase in 12 cases and compensatory hyperperfusion around the mass was seen in six cases(eight cases if include arterial CT). Encasement of tumor vessel was seen in 12 cases, and hypertrophy of feeding vessel in nine cases. On portogrphy, the filling defect on segmental portal branch could be demonstrated only in 11 cases. Shape of the portal defect was tapered narrowing in six cases, abrupt narrowing in two cases but intraluminal nodular filling defect was not seen. Remainning three cases were difficult to define the shape. On seven cases of CT during arterial portography, three cases showed mass shaped defect and four showed segmental defect but three of them could demonstrate the partially preserved portal flow in defective portal area. CONCLUSION: Hepatic arteriography in peripheral cholagiocarcinoma showed no evidence of hypertrophy of tumor vessels and tumor stain extending to central portion but peripheral staining on late hepatogram phase and compensatory hyperperfusion could be seen. Portal vein was more commonly involved through perivascular connective tissue invasion rather than by direct extension into the portal lumen.
