Neuroleptic malignant syndrome is a rare, but potentially life-threatening adverse event associated with the use of neuroleptic agents. We describe the case of a 47-year-old schizophrenic woman who was treated with clozapine for years. The patient developed acute renal failure with pulmonary edema, and underwent mechanical ventilation and hemodialysis.

3.Functional Visual Loss in Children.
Journal of the Korean Ophthalmological Society 1996;37(12):2118-2124
Funtional visual loss is the state of visual decrement without specific underlying organic causes. There had been no report in childhood in Korea. We reviewed the children's cases retrospectively to show the clinical characteristics that had been diagnosed functional visual loss. They visited one pediatric ophthalmologist in Seoul National University Hospital from August, 1988 to September, 1994. The numbers of the children who finally diagnosed in functional visual loss were sixteen, and the average age at diagnosis was 8.8 years. The prevalence was 1.04 % every year, and their chief compIaints wew binocular visual loss in 12 children, and monocular visual loss, unstable visual acuity, binocular visual loss with color sense abnormality, and binocular visual loss with strabismus in each 1 child. Their previous diagnosis before visiting our hospital was consisted of amblyopia in 11 children, optic atrophy in 1 child and retrobulbar neuritis in 1 child. Finally the 16 children proved to have normal visual acuity through fogging test using phoropter and their other problem also proved to be normal except one child who was anxiety disorder. We explained the state of patient to parent and did supportive therapy to the patient and parents. There were no recurrence of visual loss in our cases. As above the resuIts, functional visual loss in childhood was intended to diagnose to amblyopla or optlc neuropathy. So we should do careful examination not to waste efforts or costs.

We investigated the effect of topical application of retimids on the corneal neovascularization in the rat induced by chemical cauterization. The center of corneas of Wistar rats were Cauterized with a silver/potassium nitrate applicator for 5 seconds. And then they were treated topically with 0.1%, 0.2%, 0.5%, 2.0% all-trans retimids (retinol, retinoic acid, retinaldehyde) and dimethyl sulfoxide as a control four times a day. After appiications of eye drops for 5 days, each rat was kined and then perfused with a mixture of 11% gelatin 10% India ink-lactated Ringer's solution. Corneal flat preparation were made, and then the percent of the corneal area occupied by blood vessels were analized by computerized image analyzer. Percent vascularization of 0.1% and 0.2% retnoids were not significantly different from control group(p>0.05). Percent vascu1arization of 0.5% retinaldehyde and all 2.0% retnoids were significantly lower than the contml group(p>0.5). These naturally occurring retinoids were effective in antiarlgiogenesis of rat cornea at relatively high concentrations (>0.5%), when treated topicany, It will be necessary to further study on more potent antiangiogenic, at lower concentration, synthetic retimids for the treatment of angiogenic diseases.

A twenty-three year old korean officer was exposed accidentally to high-tension electric current(22,900 voltage). He lost consciousness for about three days. The point of entry was the palm area of the right hand and the point of exit was the lateral area of the right thigh. He sustained second and third degree burn on the exposed area and face, neck, anterior chest, abdomen, right thigh. He subsequently developed yellow-gray foveolar lesion and macular hole, cataract, and iritis with central visual-loss in both eyes. Fluorescein angiography demonstrated the area of retinal pigment epithelial disruption. We suspected that it was electric current induced full-thickness macular hole, not photochemical macular hole, because his companion did not seeing a bright flash light and successively central visual loss.

PURPOSE: Perceived color of ceramics changes by the spectral power distribution of ambient light. This study aimed to quantify the amount of shifts in color and color coordinates of clinically simulated seven all-ceramics due to the switch of three ambient light sources using a human vision simulating spectroradiometer. MATERIALS AND METHODS: CIE color coordinates, such as L*, a* and b*,of ceramic specimens were measured under three light sources, which simulate the CIE standard illuminant D65 (daylight), A (incandescent lamp), and F9 (fluorescent lamp). Shifts in color and color coordinate by the switch of lights were determined. Influence of the switched light (D65 to A, or D65 to F9), shade of veneer ceramics (A2 or A3), and brand of ceramics on the shifts was analyzed by a three-way ANOVA. RESULTS: Shifts in color and color coordinates were influenced by three factors (P<.05). Color shifts by the switch to A were in the range of 5.9 to 7.7 DeltaE*abunits, and those by the switch to F9 were 7.7 to 10.2; all of which were unacceptable (DeltaE*ab > 5.5). When switched to A, CIE a* increased (Deltaa*: 5.6 to 7.6), however, CIE b* increased (Deltab*: 4.9 to 7.8) when switched to F9. CONCLUSION: Clinically simulated ceramics demonstrated clinically unacceptable color shifts according to the switches in ambient lights based on spectroradiometric readings. Therefore, shade matching and compatibility evaluation should be performed considering ambient lighting conditions and should be done under most relevant lighting condition.
