Telangiectasia is characterized by permanently dilated small vessels usually arising from the suprapapillary plexus of venule capillaries, or arterioles. It may be etvlogically divided into the primary and secondary types. Rosacea, varicose vein, prolonged sun xvsure, radiation, and physical trauma may be the causes of secondary telangiectasia. We report herein a case of secondary telangiectasia associated which operation for a femur fracture.

Nevus flammeus is a benign but cosmetically devascating congenital inalformation involving mature capillaries. The copper vapor laser is a therapeutic device which had been newly applied to this. Yellow copper vapor light is absorbed by the intraluminal oxyhemoglobulin mo ecules, leading to the destruction of blood vessels. This study was undertaken to evaluate the histobigic findings in a patient with nevus flammeus according to the sequential time after copper vapor laser therapy. The results were as followed, One hour after treatment, nonspecific damages to the epidermis and upper part of the dermis were observed. The specific damage to the vessels which showed thrombi formations and partial disruption of the vessel walls was prominent. One cay after treatment, degeneration of the epidermis and sepaiation of the dermoepidermal junction were apparent. Three days after treatment, extravasations of a small amount of erythrocytes and inflanimatory cell infiltrations were present, especially around the vessels. Seven days after treatment, the capillaries showed a deposition of fiorinoid material around themselves. Partial disappearance of the vessel walls was seen. There was hisi ologic evidence of the replacement of abnormal ectatic vessels by normal appearing vessels with small uminal diameters, surrounded by endothelial cells.

4.The Effect of Retinoic Acid on Experimentally-Induced Proliferative Vitreoretinopathy in the Rabbit.
Journal of the Korean Ophthalmological Society 1997;38(10):1755-1763
The proliferative vitreoretinopathy was a complication followed by operation of rhegmatogenous retinal detachment. It was the mot, comon cause of a failure of retinal detachment surgery. It was characterized by the growth of cellular fibrous membrance in detached both retinal side and vitreous and also developed by giant retinal dialysis, posterior segmental trauma, excessive cryotherapy, endophthalmitis, retianl vascular disease. In order to prevent and treat of proliferative vitreoretinopathy, various methods of operation and drugs have been researched. We executed the experiment using the rabbit to observe the effect of retinoic acid that is known by inhibition of migration and proliferation of retinal pigment epithelial cell and fibroblast in vitro. With 121 eyes of rabbit, we induced the proliferative vitreoretinopathy by injecting of human retinal pigment epithelial cell, human fibroblast, and rabbit fibroblast into eyeball of rabbits. The extent of proliferative vitreoretinopathy was compaired by injecting those cells with the group that was injected by retinoic acid and control. The result was that in those cell groups, the extent of proliferative vitreoretinopathy was significantly higher in the rabbit fibroblast group than the other two groups(P<0.05). And in the groups that were injected retinoic acid, when subconjuctivaly injected(0.3mg/0.3ml), proliferative vitreoretinopathy was effectively suppressed and when intravitrealy injected (0.05mg/0.1ml), vitreoretinopathy was more increased than the control group. This result was probably caused by high concentration of retinoic acid in vitreous and further evaluation with various concentration of retinoic acid is needed. In conclusion, we recommend a rabbit fibroblast and subconjunctival injection of retinoic acid for the study on the suppressive effect of proliferative vitreoretinopathy.

Phthisis bulbi, resulting from repeated ocular inflammation and infection or ocular trauma, causes various degeneration of ocular tissue as well as changes in ocular external shape. It shows the impression of scleral thickening with calcification of ocular tissue and an unusual ossification as well. Having observed 31-year-old patients of phthisis bulbi and band keratopathy caused by repeated operation after ocular trauma years ago, we extracted the tan brown colored shell-like firm tissue in posterior segment and report sclerotic impression of some of ocular tissue and histopathologic finding of the typical ossificationof ocular tissue during the course evisceration.

BACKGROUND: There has been no statistical study of dermatoses in the Ganganm area of Seoul which has been rapidly developing in the last 10 years. OBJECTIVE: We evaluated the recent distributions of dermatoses in the Gangam area of Seoul and compared them with the previous reports in Seoul and other provinces of Korea. METHODS: 47,015 new outpatients who visited the Yongdong Severance Hospital from 1983 to 1992 were analyzed statistically RESULTS: The study results are summarized as follows: 1. Among the 47,015 outpatients, the total number of number of male patients were 20,180(42.9%) and female patients 26,835(57.1%). 2. In age distribution, the most frequent age groups were the 3rd decade(21.3%), the lst decade(19.5%), and the 4th decade(19.2%) amounting to 60% of the total outpatients. 3. The most common 15 dermatoses were dermatophytosis, atopic dermatitis, urticaria, irritant contact dermatitis, acne vulgaris, allergic contact dermatitis, seborrheic dermatitis, other eczemas, warts, vitiligo, drug eruption, herpes zoster, psoriasis, bacterial infection, and syphilis. 4. Those dermatoses which showed an increasing tendency annually were seborrheic dermatitis, warts, vitiligo, and syphiiis. Dermatophytosis and bacterial infection showed a decreasing tendency. 5. Seasonal distribution showed that those diseases occurring most frequently during the summer were dermatophytosis, urticaria, allergic contact dermatitis, vitiligo, herpes zoster, and bacterial infection. The incidence of atopic dermatitis and psoriasis increased during the winter season. 6. In sexual distribution, acne, allergic contact dermatitis, and irritant contact dermatitis were more frequent in females, and the remainding common dermatoses did no show any difference. 7. In age distribution, atopic dermatitis and bacterial infection were most frequent in the lst decade. Urticaria, allergic contact dermatitis, acne, drung eruption, psoriasis, and syphilis were most frequent in the 3rd decade, with warts and vitiligo in the 2nd decade, and herpes zoster in the 6th decaded. 8. The distributions of dermotoses as disease groups were eczema(24.9%), urticaria-drug eruption (13.2%), dermatophytosis(10.7%), skin appendage disorder(10.1%), viral infection(10.1%), pigmentary disorders(4.5%), and papulosquamous diseases(4.0%) which constituted 78% of the total. 9. In patients dwelling in apartments, atopic dermatitis and molluscum contagiosumn showed a more frequent tendency in comparison to those living in house. 10. The most common 10 dermatoses among children were atopic dermatitis, urticaria, contact dermatitis, molluscum contagiosum, bacterial infection, dermatophytosis, vitiligo, other viral infections, and nevo-cellular nevi. On the other hand, the most common 10 dermatoses among the elderly were drmatophytosis, other eczemas, urticaria, herpes zoster, pruritus, contact dermatitis, drug eruption, lichen simplex chronicus, seborrheic dermatitis, and vitiligo. CONCLUSION: In contrast to earlier published report from Seoul, the infectous dermatoses, especially parasitic infestation, showed a decreasing tendency. The distribution pattern of the skin diseases did not differ fro other provinces of Korea in general.
