Hydroa vacciniforme is a very rare photosensitivity disorder. The primary skin lesion is a vesicle or bulla which then heals with vacciniform scarring. We report a case of hydroa vacciniforme recurred after 3 years period of quiescence in a 20 year-old man who had had history of the disease from the age of two. The duplication of the natural lesion, clinically and histologically, was successfully made by artificial UV-A irradiation on the patient's back.

The severe form of chronic periodontitis(CP) has been reported to be strongly associated with the presence of allele 2 of composite IL-1B(+3954) and IL-1A(+4845) genetic polymor- phisms(genotype positive). However, other studies have reported conflicting findings. These might have resulted from differences in ethnic background and disease entities. The aim of this study was to determine the distribution of IL-1A(+4845), IL-1B(+3954), IL-1B(-511), and IL-1 RN(VNTR) genetic polymorphisms in children as a future Korean population. The study population consisted of 92 children from the Dept. of Pediatric Den- tistry, Chonnam National University Hospital. Genomic DNA was obtained from buccal swab. The IL-1A(+4845), IL-1B(+3954), and IL-1B(-511) genes were genotyped by amplifying the polymorphic region using multiplex polymerase chain reaction(PCR), followed by restriction enzyme digestion and gel electrophoresis. IL-1 RN(VNTR) polymorphism were then evaluat- ed by PCR amplification and fragment size analysis in agarose gel. The allele 2 frequency was 41.3%, 4.3%, 47.8%, and 9.9% for IL-1A(+4845), IL-1B(+3954), IL-1B(-511), and IL-1 RN respectively. The frequency of genotype with allele 2 carriage for IL-1A(+4845), IL-1B(+3954), IL-1B(-511), and IL-1 RN was 77.1%, 7.6%, 63.0%, and 15.2% respectively. The allele 2 frequency in IL-1B(+3954) was significantly higher in female than in male population(p<0.05). The negative association was shown between the presence of allele 2 in IL-1B(-511) and in IL-1B(+3954), and the carriage rate of IL-1B(+3954) allele 2 tended to lower in IL-1B(-511) allele 2(P=0.056). Only 7.3% of children carried the composite genotype of IL-1A(+4845) and IL-1B(+3954). These results suggest that the polymorphism of IL-1B(+3954) and the positive composite genotype was relatively rare in Korean population.

Elastofibroma dorsi is a rare, slow-growing, ill defined soft tissue tumor that's typically found between the inferior scapula and chest wall. The characteristic findings on ultrasonography, MRI and CT usually allow the correct diagnosis and so prevent unnecessary surgical procedure. We experienced a case of bilateral elastofibroma dorsi in an 87-year-old man, and we report on this case along with a review of the literature.

This study aimed to investigate the frequent intraoperative and postoperative complications and visual outcome of phacoemulsification or extracapsular cataract extraction after vitrectomy. The authors reviewed the medical records of 30 paitients who had undergone pars palana vitrectomy and followed by cataract extraction from January, 1996 to January, 1998, and had been followed up for 3 months or longer. Associated retinal diseases included complication of diabetic retinopathy (11 cases,36.7%), vitreous hemorrhage from branch retinal vein occlusion (6 cases, 20.0%), proliferative vitreoretinopathy (4 cases,13.3%). Mean interval between two operations was 21.0 months. The most commom intraoperative complication was anterior chamber depth fluctuation (4 cases).In a few cases,we had radial tear (3 cases) in lens capsule or miosis (2 cases). The most common early postoperative complication was corneal edema and late complication was posterior capsular opacity.Postoperative visual acuity remained still or improved in 28 cases (93.37%) at postoperative 3 months. In conclusion cataract extraction after vitrectomy may be performed safely with few complications. Visual outcome was favarable but was mainly dependent on previous vitreoretinal patholgy.

OBJECTIVE: To determine the prognostic factors for local recurrence of nodular hepatocellular carcinoma after segmental transarterial chemoembolization. MATERIALS AND METHODS: Seventy-four nodular hepatocellular carcinoma tumors < or = 5 cm were retrospectively analyzed for local recurrence after segmental transarterial chemoembolization using follow-up CT images (median follow-up of 17 months, 4-77 months in range). The tumors were divided into four groups (IA, IB, IIA, and IIB) according to whether the one-month follow-up CT imaging, after segmental transarterial chemoembolization, showed homogeneous (Group I) or inhomogeneous (Group II) iodized oil accumulation, or whether the tumors were located within the liver segment (Group A) or in a segmental border zone (Group B). Comparison of tumor characteristics between Group IA and the other three groups was performed using the chi-square test. Local recurrence rates were compared among the groups using the Kaplan-Meier estimation and log rank test. RESULTS: Local tumor recurrence occurred in 19 hepatocellular carcinoma tumors (25.7%). There were: 28, 18, 17, and 11 tumors in Group IA, IB, IIA, and IIB, respectively. One of 28 (3.6%) tumors in Group IA, and 18 of 46 (39.1%) tumors in the other three groups showed local recurrence. Comparisons between Group IA and the other three groups showed that the tumor characteristics were similar. One-, two-, and three-year estimated local recurrence rates in Group IA were 0%, 11.1%, and 11.1%, respectively. The difference between Group IA and the other three groups was statistically significant (p = 0.000). CONCLUSION: An acceptably low rate of local recurrence was observed for small or intermediate nodular tumors located within the liver segment with homogeneous iodized oil accumulation.

Arterial trauma associated with hip fracture treatment is still a rare complication. We present a case in which an arterial injury was discovered during closed reduction and intramedullary nail fixation of a subtrochanteric hip fracture. The preoperative thigh circumference was increased due to severe swelling, and the vascular injury was located substantially proximal to the fracture and the instrumentation area. An interventional angiogram revealed a damaged vessel originating from one of the minor proximal branches of the right deep femoral artery while filling a 2 cm-sized pseudoaneurysm. Embolization was performed without further complications.
