A 40 year-old female was admitted to our hospital because of proptosis for 4 years. Detecting a 2 cm-sized retrobulber mass on computerized tomography, we extracted well capsulated reddish brown mass, which confirmed as a cavernous hemangioma by histologic examination. One year postoperatively, her proptosis was gone, visual acuity was normal, and ocular motility was good.

Breast cancer is a common cancer in women and the most common primary tumor metastatic to the skin. Cutaneous metastasis from breast cancer occurs predominently through lymphatic dissemination. Alopecia neoplastica is rare and probably caused by the hematogenous spread of the internal carcinoma. It has diagnostic importance because it may be the first sign of an undiscovered internal malignancy. We report a case of a 40-year-old female who showed alopecia neoplastia secondary to an invasive intraductal carcinoma of the breast.

PURPOSE: To demonstrate the characterization calretinin-immunoreactive displaced amacrine cells in the ganglion cell layer using immunohistochemistry and electron microscopy. METHODS: For immunohistochemistry, sections from guinea pig retina were incubated with mouse monoclonal antibody directed against calretinin. For double label studies, sections were incuated in mixture of mouse monoclonal anti-calretinin or rabbit polyclonal anti-calretinin with following antibodies: goat polyclonal anti-ChAT, rabbit polyclonal anti-GABA, mouse monoclonal anti-GABAA receptor alpha1, beta2/3. Sections were analyzed using Bio-rad Radiance Plus confocal scanning microscope. Stained sections from three guinea pig were observed with transmission electron microscope. RESULTS: Calretinin immunoreactivity was present in displaced amacrine cells and ganglion cells gaving rise to processes ramified in the inner part of the inner plexiform layer in stratum 4. The same stratum was also occupied by the dendrites of ON-cholinergic amacrine cells. Double-labeling demonstrated that dendrites and cell bodies of displaced amacrine cells colocalized with ON-cholinergic amacrine cells and dendrites of ganglion cells directly overlapped with dendrites of ON-cholinergic amacrine cells. The synaptic connectivity was identified by electron microscopy. Ganglion cell dendrites received synaptic input from ON-cholinergic amacrine cell. GABAA receptor beta2/3 subunit bands cofaciculates the dendrites of displaced amacrine cell and ganglion cell that are juxtapose to the alpha1 subunit of GABAA receptor. CONCLUSIONS: These results indicate that ON-cholinergic amacrine cells modulate calretinin-labeled ganglion cell via GABAA receptor beta2/3 in the guinea pig retina.

We report a case of a 59 year-old female with hyperlipoproteinernia who had xanthoma tuberosum, xanthoma tendinosurn and xanthoma planum. Yellowish nodules appeared on the right elbow 26 years ago and the lesions gradually increased in size and spread to the elbow, hand, knee, foot and achilles tendon. Except for the skin lesion, she was normal on physical examination. The laboratory findings showed that the serum cholesterol, beta lipoprotein and total lipid were increased. The beta band was rnarkedly elevated on electrophoresis, which suggested type IIa hyperlipoproteinemia. Histopathological findings shc wed many aggregates of foam cells and foreign body giant cells were seen in the dermis.

BACKGROUND: Skin contact with metalworking fluid(MWF) remains a frequent cause of occupational dermatitis. However, no precise data is available about sensitization in metalworkers exposed to MWF in Korea. OBJECTIVES: The purpose of this study was to evaluate the prevalence of contact sensitivity among metalwokers who handle MWFs and to investigate the suitability of a screening test with MWFs being actually used in metalworkers. METHODS: An epidemiological study was performed using a'questionnaire in 771 workers in 9 derpartments of a motor company. 278 out of 771 workers had actual contact with MWF. Patch tests were performed in 73 metalworkers who had suspected dermatits in relation to exposure of MWF, which was selected via interviews and dermatologic examinations. Patch tests were included with a routine series of common components of MWF(materials obtained from Chemotechnique, Sweden), a solvent series and several dilutions of various crude MWFs(8 species) RESULTS: Contact sensitization was established in 14 metalworkers(5% of 278). Sensitising substances were biocide(6 cases), corrosion inhibitors(2 cases), emulsifiers(2 cases), biostatic substances(1 cses) and others(4 cases). Therefore 10 out of 14 metalworkers had true occupational allergic contact dermatitis. 10 out of 73 screening patch tests showed positive reactions to MWF elements, and 9 people who were positive to MWF elements showed positive reactions to crude MWF, but 1 person did not. CONCLUSION: The prevalence of occupational allergic contact dermatitis(3.5% of 278) was low. The screening patch test by crude MWFs actually used in metalworkers may give false negatives. Therefore for the purpose of diagnosis of allergic contact dermatitis, we need a process of patch tests with MWF elements.

STUDY DESIGN: This is a retrospective study evaluating the efficacy of new surgical technique for treatment of fixed lumbosacral kyphosis. OBJECTIVES: To report a new method of vertebral column resection and to determine its efficacy in the treatment of fixed lumbosacral kyphosis. SUMMARY OF BACKGROUND DATA: The treatment of fixed severe spinal deformity is very difficult and only a few surgical methods are reported. The vertebral column resection from anterior and posterior is a radical method to treat the severe deformity but it has many problems with anterior and posterior approachs. MATERIALS AND METHODS: A new surgical method of vertebral column resection from posterior approach only(PVCR) was carried out in 5 patients of fixed lumbosacral Tb kyphosis from October 1997 to March 1998. The mean age was 43.4 years(range 35-61 years), and four were female and one male. The average postoperative follow-up period was 5.5 months(ranged from 2 months to 12 months). An average of 2.6 vertebrae was resected. The degree of sagittal curves was measured using the Cobb technique preoperatively and postoperatively. the rejional lumbosacral kyphotic angle and compensatory thoracic curvature from 74 to 712. The sagittal imbalance was measured by distance from C7 plumb line to postero-superior corner of 51 using 14 x 36 inch standing lateral radiograph. RESULTS: The sagittal deformities were corrected from an average of kyphosis 37.4 to lodosis 8.4 at lumbosacral level and from an average of lodosis 31.6 to lodosis 8.2 at thoracic level. The sagittal imbalance was improved from an average of +11.7cm to +2.2cm, for a posterior immigration of 9.5cm. The mean operating time was 334 minutes and with an average blood loss of 4338m1. Complication comprised of motor weakness with deep wound infection in one case and superficial wound infection in another case. The transient hip flexor weakness was seen in all the patients. The hip flexor power recovered in 3-4 weeks. The patient of motor weakness and deep infection showed partial motor improvement and complete wound healing at last 2 month follow-up. CONCLUSION: one-stage posterior vertebral column resection is a promising technique for treatment of the severe fixed lumbosacral kyphosis.
