The term "pineal anlage tumor" has been recently proposed and few cases have been reported. We report the first Korean case of pineal anlage tumor in a 6-year-old girl who complained of headache and vomiting for 2 months. Brain MRI revealed a well defined, lobulated, calcifying mass in the pineal region. Tumor was totally removed. Pathological examination revealed a primitive pineal parenchymal tumor with melanotic epithelial component that was similar to histologic findings of melanotic neuroectodermal tumor of infancy, so-called retinal anlage tumor and of the developing pineal gland. The tumor was composed mostly of small, undifferentiated cells, Flexner-Wintersteiner rosettes, and ganglionic differentiation. The tumor also contained the cartilage and skeletal muscle cells.

The cryopathic hemolytic anemia is an autoimmune hemolytic anemia induced by cold antibody. Authors report a case of cryopathic hemolytic anemia confirmed by immunohematologic examination. A 22-year-old man was admitted at Kyung Hee Medical Center in March, 1994, with a past history of Kleinerfelter's syndrome and complained jaundice as well as dizziness. Direct antiglobulin test using polyvalent and anti-C3d monovalent antisera was positive, but was negative against anti-IgG, anti-IgA, and anti-IgM monovalent antisera. Cold agglutinin titer was as high as 1:1024 at 4 degrees C and anti-I specificity was confirmed by using cord bloods. The patient was not improved despite transfusion of washed red cells and administration of prednisolone, and on 16th day of hospitalization he manifested sudden episode of headache and loss of conscioussness, soon followed by death.

The association rate of antibody with antigen has been reported to be greatly increased by lowering ionic strength. Low-ionic strength salt solution(LISS) method has been used for the detection of various alloantibodies. To investigate the sensitivity of LISS in indirect antiglobulin test, a comparison study of LISS with saline and albumin methods was conducted. A total of 32 patients' samples requested for indirect antiglobulin test were evaluated. Out of 32 patients with clinical immune hemolytic anemia, 11(34.3%) were positive in 37 degrees C saline antiglobulin test, 18(56.2%) in albumin antiglobulin test, 23(71.8%) in LISS antiglobulin test respectively. These results were statistically analyzed using non parametric Page's test for ordered alternatives. LISS method is more sensitive than 37 degrees C saline method or albumin method significantly (p<0.01).

Callus is a nonpenetrating circumscribed hyperkeratosis produced by repeated friction or pressure. It occurs on parts subjected to intermittent pressure, particularly on the palms and soles, and particularly over the bony prominences of the joints. In painful callosities of the feet, ill-fitting shoes and orthopedic problems of the foot (bunions, exostoses) are some of the etiological factors to be considered. Gout is a condition of inborn metabolic and/or acquired form of the disease characterized by hyperuricemia, tophaceous deposits of sodium urate and recurrent attacks of arthritis. We present a case of callus caused by tophi. The patient was a 45-year-old man who had complained of a painful, well-demarcated, hyperkeratotic plaque on the heel of the left foot for 18 months. After the tophi beneath overlying whitish thickened skin had been removed, the skin lesion disappeared and to date has not recurred.

BACKGROUND: Cyclosporin A (CsA), a potent immunosuppressant, has been reported to be effective in the treatment of severe atopic dermatitis (AD). OBJECTIVE: The aim of this study was to evaluate the efficacy and side-effects of CsA in Korean patients with severe AD. MATERIALS AND METHODS: 16 patients with recalcitrant AD took CsA for at least 6 weeks. Among them, 11 patients were followed up for more than 16 weeks. Initial dose was 5mg/kg/day (maximum 300 mg/day) and the dose was reduced according to their therapeutic responses. SCORAD (Scoring AD) was used to evaluate clinical efficacy of CsA. During the 1st month of therapy, the therapeutic efficacy and side-effects were evaluated every 2weeks and after 1 month, every month. We checked blood pressure and laboratory abnormalities including liver function test, blood urea nitrogen (BUN), creatinine (Cr) and urinalysis at each visit in addition to observing clinical adverse effects. RESULTS: Significant reduction of SCORAD was noted in 15 patients after 6 weeks of CsA therapy. Only one patient stopped CsA therapy because of the elevation of blood pressure. Three patients showed albuminuria, which disappeared after CsA dose reduction. CONCLUSION: CsA can be used effectively and safely in severe Korean AD patients. Albuminuria seems to be a peculiar side-effect in Korean patients.

PURPOSE: We performed the study prospectively to evaluate the advantage of fat suppression MR in the diagnosis of rotator cuff injury. MATERIALS AND METHODS: Ten symptomatic patients were studied with both conventional T2WI and FST2WI using chemical shift technique. Each image was analyzed for the assessnent of injuries, conspicuity of the lesion, the presence of effusion in subacromial bursae and joint space, and presence of humeral head injury. Arthroscopy was done in 4 patients following MRI. RESULTS: We could made presumptive diagnoses on FSMR as identical as on conventional MR in six cases(1 normal, 2 tendinitis, 2 partial thickness tear, 1 full thickness tear), two of them were confirmed by arthroscopic procedures. Two cases of partial thickness tear proved by arthroscopy were detected on FST2WI, whereas they were considered tendinitis on conventional T2Wl. There were another 2 cases who showed tendinitis on FSMR, but normal on conventional T2Wl. They, however, were not confirmed by either arthroscopy or surgical procedure. CONCLUSION: We found the FSMR were superior to conventional T2Wl in the conspicuity of lesions and detection of joint effusion and abnormalities on the humeral head. We think FSMR of the shoulder could have significant diagnostic advantages over the conventional spin-echo MR imaging.

We report the results of field operation of TELEACE system between Kyung-Pook National University Hospital and Ul-Jin Goon Health Care Medical Center from December, 1990 to September, 1991, which had been operated as a kind of Integrated Services Digital Nework projects by KOREA TELECOMMUNICATION Inc. Ul-Jin Goon Health Care Medical Center transmitted 414 plain radiographs to our hospital in speed of 9600BPS. Each image was composed of 1024X1024 pixelsX8 bits/pixel. In our hospital, the image files were displayed on high resolution monitor (1280×1024 pixets). Text files of image interpretations were transmitted to the health care medical center. The two radiologists who had interpreted the transmitted images, went to the health care medical center and read radiographic film with blind test method. We obtained the following results: false negative rate of 6.3%, false postitve rate of 2.4%, mean sensitivity of 81.4%, mean specificity of 96.3%, and mean accuracy of 91.3%. In predictive value of 0.05, there was no significant difference between results of these two types of radiographs. In conclusion, TELEACE system was valuable to the clinicians isolated from services of radiologists.
