1.Molluscum contagiosum occuring in an epidermal cyst.
Korean Journal of Dermatology 1992;30(6):917-919
We report a case of molluscum contagiosum occurring in an epidermal cyst. A-38-year old male patient had the lision which was a 1.2 x 1cm sized, elevated, round nodule on the right cheek. Histology showed true epidermal cyst containing molluscum bodies throughout the cyst wall and laminated keratotic material within the cyst itself.

We have experienced automated and computerized perimetry using a Humphrey Field Analyzer in our Glaucoma Services. To evaluate its clinical efficacy, we report the results of the Armaly central field screening test in comparison with those of central 30-2 threshold test of the Humphrey Field Analyzer. One hundred fortythree eyes of 83 cases of normotensives, ocular hypertensives and glaucoma patients with open-angle or narrow-angle were enrolled in this study. Fiftyfour out of 61 patients (88.5%) and 73 out of 81 eyes (90.1 %) with visual field defect were detected by the screening test of the Humphrey Field Analyzer. Eight out of 81 eyes (9.9%) with visual field defect detected by the screening test were confirmed as false positive. All points of false positive were solitary, which tended to occur more frequently on superior vusual field. False negative of 8 eyes (12.9%) detected by the screening test were confirmed by the threshold test. The point of false negative was more frequent on superior field and showed to locate more peripherally from the fixation point. There was no significant difference in either central sensitivity or age of the false ring.

The T cell responses to hepatitis B surface antigen (HBsAg) were analyzed in acute hepatitis patients, chronic active hepatitis (CAH) patients and asymptomatic carriers. Neither proliferative responses nor substantial cytokine production of peripheral blood mononuclear cells (PBMC) in response to HBsAg was detected. For further studies, HBsAg- reactive T cell lines were prepared from PBMC of the hepatitis patients and asymptomatic carriers. No proliferative response of the T cell lines was observed. Interestingly, however, T cell lines obtained from acute hepatitis patients were found to produce IFN-r, but not IL- 4, in response to HBsAg stimulation, whereas T cell lines obtained from CAH patients and carriers were not. Results of this study suggest that HBsAg-reactive T cells producing Thl type cytokines may play an important role in the viral clearance during acute infections, while defects in those T cells may be responsible for the viral persistency.

We herein report a 4-year-old boy with infantile digital fibrornatosis developing on the distal & middle phalanx portion of the right index & ring fingers, and the middle phalanx portion of the right middle finger, which started at the age of 5 months after birth. Biopsy specimen taken from the right middle finger showed the proliferating collagen bundles and fibroblasts in the dermis and eosinophilic cytoplasmic inclusions within the fibroblasts. Although we attempted to treat tbe patient with intralesional injection of triamcinolone acetonide suspension and cryotherapy 5 times biweekly, there was no signifit effect.

PACS (Picture Archiving and Communications System) is a computer-based image storage and retrieval system that can store, recall and display medical images rapidly on high resolution workstations. The image acquisition system consists of direct digital interface to computed radiography (CR) system. We reviewed X-rays of 84 patients who had both studies of Dual energy X-ray Absorptiometry (DXA) and AP, lateral views of lumbar vertebrae between January and December of 1995. We tried to verify the clinical implication of pixel values on PACS for DXA by comparing pixel values and bone mineral density (BMD) of the 2nd, 3rd and 4th lumbar vertebrae. They were all female between 44 and 72 years old, average age of 59. Bone mineral density (BMD), represented in DXA of a total of 252 vertebrae were mostly in the range of between 0.228 (22%) and 1.318 (121%). Pixel values of the AP and lateral views of the 2nd, 3rd and 4th vertebrae in the PACS workstation were closely correlated to bone mineral density (p=0.0001). The values of the DXA (bone mineral density and T score) get comparatively lower as the pixel values get smaller. In conclusion, the pixel value on PACS interfaced to CR could be utilized as an easy, speedy and economical tool for screening of osteoporosis.

BACKGROUND: Isocitrate dehydrogenase (IDH) catalyzes the oxidative decarboxylation of isocitrate to yield alpha-ketoglutarate (alpha-KG) with production of reduced nicotinamide adenine dinucleotide (NADH). Dysfunctional IDH leads to reduced production of alpha-KG and NADH and increased production of 2-hydroxyglutarate, an oncometabolite. This results in increased oxidative damage and stabilization of hypoxia-inducible factor alpha, causing cells to be prone to tumorigenesis. METHODS: This study investigated IDH mutations in 61 Ewing sarcoma family tumors (ESFTs), using a pentose nucleic acid clamping method and direct sequencing. RESULTS: We identified four cases of ESFTs harboring IDH mutations. The number of IDH1 and IDH2 mutations was equal and the subtype of IDH mutations was variable. Clinicopathologic analysis according to IDH mutation status did not reveal significant results. CONCLUSIONS: This study is the first to report IDH mutations in ESFTs. The results indicate that ESFTs can harbor IDH mutations in previously known hot-spot regions, although their incidence is rare. Further validation with a larger case-based study would establish more reliable and significant data on prevalence rate and the biological significance of IDH mutations in ESFTs.
