Injectable Collagen Implan, is composed of purified bovine dermal collagen emulsified in saline and lidocaine(0.3%) base, and has been promoted for correction of soft tissue contour defects. Although collagen is a relatively nontoxic, nonimmunologic and biolegically nonreactive biomaterial, some side reactions have been reported. We report herein a case of cutaneous side reaction to collagen implantation in a 38-year-old female. The patient presented with puritic, irritating, multiple, erythematous nodules on both the temporal and interorbital area, which had been observed since 1 day after collagen(KOKEN ATELOCOLLA-GEN IMPLANT-Japan) implantation. Histopathologic findings showed dense infiltration of acute and chronic inflammatory cells in the dermis, especially the perivascular and periadnexal area.

Optic disc pits are an uncommon congenital anomaly of the optic nerve head. Serous detachment of the macula is a well known complication in patients with an optic disc pit Although spontaneous reattachment has been reported, most eye with macular detachment associated with optic disc pit have a poor visual prognosis inspite of treatments. We have experienced a case of optic disc pit associated with serous macular detachment, that has been treated with argon pure green laser photocoagulation, reporting it with a review of literature.

The computerized image analysis is a useful tool for the quantitative assessment of histopathologic findings. In contrast to the usual microscopic examination by pathologists, the computerization should be accompanied with the standardization process of the image. We developed an algorithm to standardize images and to determine the optimal gray level threshold, using a myocardial fibrosis model. Sirius red staining was more convenient for the image analysis than Masson's trichrome staining because of a better contrast with the surrounding structures. To get an optimal measurement, light intensity was standardized at each of the fibrosis, myocardium and background. In this study, the most promising method to determine the degree of fibrosis was that of revising the background without tissue to a gray level of 200, obtaining a green component of the color image, revising the myocardial fiber to 163, and defining a partial ratio as fibrosis index when the gray level threshold was 120. These threshold levels and parameters were determined after drawing the binarization index curves according to the change of the gray level threshold and by the morphological examination of the actual binarization figures overlaid to the original color image. Through these processes we could get a consistent result on the myocardial fibrosis and we expect a similar principle applies when we analyze color images in the histopathologic quantitation by computerized image analysis.

Leiomyosarcoma arising in the skin is rare tumor, and diagnosis usually is made microscopically. After local excision, these lesions recur in large proportion of pat ients. The authors herein report a 53-year-old male with leiomyosarcoma appeared in the skin of the right forearm and presenting as a dark reddish colored, 5*6cm in diameter, superficial ulcerated single firm nodule with intermittent pain. Histopathological examination showed poorly circumscribed tumor consisting of interlacing bundles of spindle shaped smooth muscle cells in the middle and lower parts of the dermis. The nuclei were hyperchromatic, large, vacuolated, and irregular in shape. Electron microscopic findings revealed cytoplasmic organelles such as rough endoplasmic reticulum and mitochondria of malignant smooth muscle cells in the paranuclear area, Characteristic subsarcoelmmal caveolae and dense plaque were noted and myofilaments were distributed in the peripheral cytoplasm. The tumor did not recur in 10 months' follow-up.

8.Clinical Study of Traumatic Hyphema.

Journal of the Korean Ophthalmological Society 1992;33(3):279-286
We reviewed 114 patients who were admitted and treated at the Chonju Presbyterian Medical Center between 1986 and 1990 for nonperforating traumatic hyphema. Of these 114 cases, 103 (90.4%) were male and 11 (9.6%) were female. Mostly, they were under 20 years of age. Grade I hyphema (bleeding less than one third of anterior chamber) was 72 cases (63.2%). The causes of injuries were blows to the eye (56 cases, 49%) and projectile objects (45 cases, 39.5%). Associated injuries to the eye and periocualr structures occurred in 78 patients (68.4%), which were angle recession (23.7%), eyelid laceration (20.2%), increased intraocular pressure (16.7%), traumatic cataract (14.0%). Secondary hemorrhage occurred in 15 patients (13.2%) and was significantly more frequent among patients whose initial hyphema filled more than one therd of the anterior chamber. The final visual acuity were worse in eye with associated ocular injuries such as vitreo-retinal disorders, traumatic cataracts, etc.
