Purpose: The characteristics of pediatric dermoid cyst patients. Methods: This was a retrospective chart review of 64 dermoid cyst patients (65 eyes) aged < 18 years. Results: Limbal dermoids and conjunctival dermolipomas were observed in 49 and 16 eyes (48 and 16 patients), respectively. Limbal dermoids were more common in the left eye (61%), particularly on the inferotemporal side (80%). Three (6%) of the patients were diagnosed with Goldenhar syndrome. The horizontal diameter (3.76 ± 1.30 mm) was greater than the vertical diameter (3.74 ± 1.30 mm). Most of the lesions were yellow (35.2%) in color, mildly elevated (n = 19, 55.9%), and not visible when the eyes were closed. The mean best corrected visual acuity was 0.8 ± 0.2 in 23 patients, with mean astigmatism and mean corneal astigmatism values of -2.1 ± 2.2 diopters (D) and -2.0 ± 1.1 D, respectively. None of the conjunctival dermolipoma patients had any ocular history. The left eye (75%), particularly the temporal and superiotemporal conjunctival fornix, was the most commonly affected site. The mean best corrected visual acuity was 0.9 ± 0.0 in seven patients, with an average astigmatism of -0.3 ± 0.2 D. Conclusions Dermoid cysts are congenital benign tumors that may be associated with congenital diseases. They vary in size, location, color, and extent of invasion, and may cause functional problems, such as astigmatism and amblyopia. Therefore, timely surgical treatment is desirable.

BACKGROUND: As determined from the recent investigations of discordant cardiac xenotransplantation, hyperacute rejection occurs mainly at the endothelial cells in donor microvascular systems, but this does not occur at cardiac valve leaflets or at medium-to-large caliber vessels. On the basis of this background, this study was performed to look into the biocompatibility for transplantation of a middle or large diameter xenogenic blood vessel by conducting xenogenic arterial transplantation with the carotid artery in a pig-to-goat model. MATERIAL AND METHOD: The experimental group was composed of 10 pairs of pig-to-goat combinations. They were divided into each period of 1 week, and 1, 3, 6 and 12 months. Four carotid artery grafts obtained through collection of the bilateral carotid arteries from two pigs were preserved at -70degrees C without other treatment, and then they were transplanted into the bilateral carotid arteries of two goats. Doppler ultrasonography was done on a periodic basis after transplantation to evaluate the patency of the grafted blood vessel. At the ends of a predetermined period, the grafts were explanted from the goats and they underwent gross examination. Hematoxylin-eosin and Masson's trichrome staining were conducted. In addition, in order to examine the immunological rejection of the grafted xenogenic blood vessel, immunohistochemical staining was conducted with T-lymphocyte indicator and von Willebrand factor. RESULT: Two goats at the each one-week period and the one-year period died during the experimental period because of a reason unrelated to the experimental procedure, and the remaining 8 goats survived until the end of each experiment period. On Doppler ultrasonography, unilateral carotid artery occlusion was found in a goat, whose period was specified as 3 months, among the 8 survived goats. However, the vascular patency was maintained well and there was no graft that formed aneurysms in the other goats. On gross examination, the region of vascular anastomosis was preserved well, and calcification of the grafted blood vessel was not shown. Histologically, the endothelial cells of the graft disappeared one week after transplantation, and then there was progressive spread of the recipients' endothelial cells from the anastomotic site. The reendothelialization occurred over the whole graft at one month after transplantation. The neointimal thickening and adventitial inflammation became severe by 3 months after transplantation, but this lessened at 6 months and 12 months, respectively. The rate of CD3 positive cells was very low among the infiltrated inflammatory cells. CONCLUSION: The fresh-frozen xenogenic artery kept its patency without being greatly influenced by xenogenic immune reaction.

Although many methods have been developed to correct the aging process of the head and neck, the correction of nasolabial folds still remains a difficult area. The difficulty of correcting nasolabial fold is due to the anatomical location and the difference of aging process. From March 2000 to February 2001, the authors operated on 10 aging face patients using face lift with SMAS and FAME(Finger-assisted malar fat pad elevation) technique. The authors repositioned the SMAS-platysma flap posterosuperiorly and used finger dissection of the malar fat pad enabling a 3-dimensional correction and repositioning of the fat pad without detachment of the zygomatic ligament. The finger dissection of the malar fat pad attached to the skin enables a more anatomical correction of the malar fat pad with a more natural looking layer and longer lasting results in addition to decreased hematoma, edema and postoperative pain compared to previous methods.

We herein report a case of occupational contact urticaria syndrome induced by cefotiam di-hydrochloride in a nurse. She had generalized pruritic wheals accompanied by palpitations and tachypnea during the preparation of cefotiam solution. A scratch patch test with cefotiam di-hydrochloride, a major component of cefotiam ingredient showed multiple erythema and wheals within 5 minutes, accompanied by palpitations and tachypnea. No delayed type reaction was observed. Based on her clinical history and scratch test result, we diagnosed her condition as contact urticaria syndrome caused by cefotiam.
