The hydroxyapatites were popularly been used as the ocular implant due to low incidence of post-operative exposure, infections, and excellent motility. For this purpose, it has been known that the drilling and peg implantations are performed after ingrowth of fibrovascularization tissue into the hydroxyapatites, so that ball and socket movement were occur. The authors reviewed 140 patients(140 eyes) who received enucleation or evisceration with the implantation of hydroxypapatite from Dec. 1991 to Jun. 1995. We performed that drilling after confirmation of the fiborvascularized hydroxyapatite by Technetium-99m-MDP bone scan, and investigated the method and complications. Among the 140 eyes(140 Patients), 39 eyes(28%) were found to have complications: 17 cases of peg extraction(44%), 10 cases of peg protrusion(26%), 4 cases of over-growth of granulation tissue(11%), 3 cases of poor motility(7%), 3 cases of hydroxyapatite exposure(7%) and 2 cases of malposition of peg(5%). Redrilling was performed in 20 eyes(51%) and exchanged by the screw peg due to re-extraction of peg in 4 eyes(20%). In a conclusion, overall the frequency of complications after drilling was about 28% and the most frequent complication was peg extraction.

We describe a 8-year-old girl with erythrokeratodermia varibilis (EKV). This diagnosis was supported by erythematous, configurate patches over the entire body. Their size, shape and location varyed with enviromental factors and emotional state. In addition, well defined brownish, hyperkeratotic plaques were scattered over the trunk and extremities. Also, this patient had alopecia universalis, which is not typical of EKV. Etretinate therapy resulted in an almost complete clinical clearing of the plaques; however, her alopecia universalis and erythematous lesions were not affected.

Since adult human skin can be grown in chernically defined medium without serum, the skin organ culture has gained a great interest as a method for studies concerning skin biology, pharmacology and toxicology. however, serum supplementation has extensively been used to improve the viahility of tissue culture. This study was undertaken to evaluate the effect of serum on the histologic changes ohserved during the organ culture of the normal human skin. The general architecture of the skin was well maintained for 6 days with or without seru. After then, fetal calf serum or autologous human serum was found to enhance the viability of the epidermis. A confluent layer of necrotic spinous ceils was ovserved earlier and more widespread without serum. The addition of serum had an impressive effect on epibolization. In the absenee of serum, the formation of the epibolus was not only minimal, but also, susceptible to degeneration, and no epibolus remained at 10 days rif incubation. No difference can be found between fetal calf serm and autologous human serum in the formation of the epibolus. There was no favorable effect of serum on the formation of new stratum corneum. The thickness of new straturn corneum increased in parallel with the number of parakeratatic cells, increasing most rapidly between 6 and 8 days of incubation. Parakeratosis was more prominent in the presence of serurn.

We present three cases of eosinophilic pustular folliculitis without eosinophilia in a 19-year-old female, a 27-year-old male, and a 51-year-old male. Multiple erythematous plaques with papules and pustules were observed on the face in two patients and on the face, trunk, and extremities in the third patient. Histopathologic findings showed hair follicles and the sebaceous glands infiltrated with mixed inflammatory cells composed of eosinophils and neutrophils, characteristic of eosinophilic pustular follicultitis. However, peripheral blood eosinophilia was not present in any of our three cases.

Dural shunts are vascular communications in which blood flows through small meningeal branches of the carotid arteries to enter the venous circulation near the cavernous sinus. The clinical characteristics of 13 eyes[12 patients] with dural cavernous sinus fistula are described. Of these patients, 84.6%[11 eyes]were women with dilated conjunctival and episcler-al vessels, exophthalmos, retinal hemorrhage and venous engorgement, elevation of intraocular pressure, swelling of lid and orbital area, limited eye movement and diplopia, and bruit, in order of frequency. Decreased vision had occurred in only 1 eye, due to central retinal vein obstruction during follow-up periods after embolization. CT or MRI scan showed the enlargement of the extraocular muscle and superior ophthalmic vein. Two eyes had resolved spontaneously. Ten eyes of dural cavernous sinus fistula had the resolution of clinical symptoms after carotid angiography with embolization. The complications after embolization had occurred in one eye with transient sensory deficit of face.

Hertel and Naugle exophthalmometers were used to compare the variability and reproducibility, produced by various observers. Five examiners measured fifty two eyes of twenty-six normal subjects each by using two different exophthalmometers, respectively. The average coefficient of variation among five measurements was 5.6% in the right eye, 5.2% in the left eye and 2.1% in base line by Hertel exophthalmometer. The average coefficient of variation measured by Naugle exophthalmometer was 1.9% in both eyes and 0.8% in pupillary distance. In conclusion, Naugle exophthalmometer showed less variability and better reproducibility; it is more appropriate for comparative exophthalmetry.
