We report a case of 64-year-old female patient who has had factitious skin lesions for 20 years. She complained formification sense and severe itching on her face. These symptoms were improved with squeezing and bleeding. There were scuare shaped ulcerated nodule on the right cheek and white depressed scar on the left cheek. She was treated with wet dressing and occlussive dressing, and skin lesions were nearly cleared within 3 weeks, but new lesion appeared. Pimozide 2mg #1 p.o were given under the diagnosis of delusion of parasitosis from June, 1984. Her symptoms were improved without recurrence till now. Treatment with pimozide in monosymptomatic hypochondriacal syndrome is discussed.

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.

We made a clinical study on 10 cases of histiocytosis syndrome who had been admitted to the pediatric department of Soon Chun Hyang University Hospital from Jan. 1982 to Dec. 1991. The results were obtained as follows 1) The sex incidence revealed male predominance with the ratio 4:1. 2) Among 10 cases, 4 cases were classified as eosinophilic granuloma, 1 case as Letterer-Siwe disease, 1 case as linfection associated hemophagocytic syndrome and 4 cases as malignant histiocytosis. 3) The mean age of symptom onset was 4 and 7/12 years in all disease group. 4) The common clinical symptoms and signs at dignosis were dyspnea, mass, pain on lower extremities and fever. 5) The most common organ involved among 9 organ systems was liver-spleen and the number of organ systems involved were 1 in 3 2 ases(30%), 3 in 2 cases(20%), 8 in 2 cases (20%) and 6, 7 and 10 organs in each 1 case. 6) The abnormal hematologic findings (Hb; 10g/dl and/or WBC; 4,000/mm3 and/or PLT; 100,000/mm3) were found in 6 cases. 7) Low serum albumin was found in 2 cases. Results of blood culture were Pseudomonas aeruginosae and Salmonella typhi in each 1 case. 8) The common findings on tissue biopsy were histiocytic proliferation and infiltration. 9) 4 patients of MH who recieved chemotherapy, a combination of adriamycin, vincristine, cyclophosphamide and prednisone were given in a total of four courses every 2 weeks ad induction therapy. When complete response was attained, a combination of adriamycin, vincristine, prednisone (AOP) and cyclophosphamide, vincristine, prednisone(COP) was administered alternately every 4 weeks as maintenance therapy for 6-64 months. 10) Among 4 patiens of MH who recieved chemotherapy, 1 patient was lost during induction chemotherapy, for 1 day.2 patients expired during induction chemotherapy, for 1 month, 1 patient expired during maintenance chemotherapty, for 8months, Eosinophilic granuloma cases (3) were recieved currettage and no recurrence. IAHS case due to typhoid fever was improved spontaneously.

In order to elucidate the biological effects of pulsating magnetic field in in vitro culture system we designed a pulsating magnetic apparatus using 120 Hertz, 24 Volt direct current. It can generate 63~225 Gauss in the experimental area of 90 mm petri dish, and has little thermal effect on the culture media in 37.5oC, 5% CO2. Human osteogenic sarcoma (HOS) cells were cultured in the pulsating magnetic field and the nuclear changes of cultured cells were observed routinely by hematoxylin staining, and apoptotic change was detected by ApopTag staining using both peroxidase and fluorescein labelings. Compared to the control group which formed well organized whorling pattern of HOS cell line in 3 days culture, the HOS cells cultured in the pulsating magnetic field for 12 hours or 24 hours grew irregularly and showed increased number of apoptotic cells. When the flow of pulsating magnetic field was interrupted by insertion of strong permanent magnetic bar (1000 Gauss, 5530 mm) beneath the petri dish during in vitro culture, the area of sparse pulsating magnetic field showed active proliferation and aggregation of HOS cells even in 24 hour exposure group. These data suggest that the pulsating magnetic field may play a role in inducing growth retardation and apoptosis of HOS cells. Furthermore, the hazardous effects of pulsating magnetic field can be lessened or nullified by the interruption of pulsating magnetic field with a strong permanent magnetic bar.

PURPOSE: Introduction of low osmolality contrast agent(LOCA) has allowed safer, more comfortable contrast-enhanced CT examination, but there has been significant increase in image degradation when evaluating the kidneys due to streaky artifact. The authors reviewed findings of contrast-enhanced abdominal and pelvic computed tomography(CT) to know the difference of renal streaky artifact between a high osmolality contrast agent (HOCA) and LOCA. MATERIALS AND METHODS: This study included two hundred contrast-enhanced CT in 200 patients, 100 performed with HOCA(meglumine ioglicate, 150ml) and 100 performed with LOCA (iopromide, 150ml). The severity of renal streaky artifact was compared between HOCA and LOCA groups. RESULTS: Of the scans performed with HOCA, 40 had no artifact, 52 had grade I artifact, 6 had grade II artifact, and 2 had grade III artifact Of the scans performed with LOCA, 23 had no artifact, 44 had grade I artifact, 29 had grade II artifact, and 4 had grade III artifact. There was significant difference in the degree of the streaky artifact depending upon the osmolality of the contrast media used(by {{{{x^2}}}}-test, P=.0001). CONCLUSION: The results of this study revealed a statistically significant increased incidence of artifacts and distortions of renal image with LOCA when compared with HOCA.
