The authors have recently experienced a case of traumatic retinal angiopathy of 1.5 year old child which followed immediately a relatively minor injury on the head. 5 days after the accident, external examination of both eyes appeared normal and the fundi showed retinal edema, numerous superficial whitish exudates and flame-shaped retinal hemorrhages predominantly between the disc and macula. X-ray examinations of skull and chest revealed no evidence of fracture. Complete blood cell count, urinalysis, stool and cerebrospinal fluid findings were normal limits. Abnormal neurological signs were not detected. The area of exudates gradually absorbed over a period of one month but hemorrhages were still remained around the macula. The peripheral vision seemed to be improved but central fixation remained poor. 2 months later the fundi presented optic atrophy, attenuated arterial caliberation and cherry red spot at each macula.

The authors presented the fundus findings of 25 cases with ocular lesions among 67 tuberculosis in children who were referred to our ophthalmic department from pediatric ward at Busan National University Hospital and Busan Christian Children's Hospital within a year from October 1971 to September 1972. These 67 cases were composed of 33 tuberculous meningitis, 8 hilar lymphadenopathy, 17 active pulmonary tuberculosis, 2 miliary tuberculosis and 7 tuberculous arthritis and spondylitis. The results were; 1. Of 67 tuberculosis in children 25 cases (37.3%) were shown ocular lesions, some of which were multiple. 2. 19 cases of 33 tuberculous meningitis were shown eye lesions of which cases combined with hilar lymphadenopathy or miliary tuberculosis had frequently ocular complications. 3. The common findings in fundi of tuberculosis in children were pale in optic disc and small tubercles in choroid. 4. A case of bilateral tuberculous endophthalmitis in a 3 year aged orphan was presented of which case was developed in the process of tuberculous meningitis and miliary tuberculosis.

PURPOSE: To assess the usefulness of breath-hold fast MR imaging of liver with fat suppression (FS) by application of chemical saturation technique in the diagnosis of regional fatty changed suspected in sonography. MATERIALS AND METHODS: Thirteen patients who had focal lesions with diffuse, homogeneous signal changes after FS through chemical saturation technique without additional changes of imaging parameter during MR imaging of liver were selected. T1-weighed fast low-angle shot and T2-weighted turbo spin-echo sequences were obtained with or without FS during each single breath-holding session. Subjective changes of signal intensity between the pre-FS and the FS images were compared with the sonographic findings in each lesion. RESULTS: Seven lesions of decreased signal intensity after FS on T1 or T2-weighted images, including three lesions only at FS T1 images, were regarded as focal fat infiltration. All seven lesions had compatible sonographic findings as homogenously echogenic areas. Another six lesions of subjectively increased signal intensity including two lesions only at FS T2 images were regarded as focal fat sparing. All six lesions had sonographic findings as homogenous echo poor areas suggesting focal fat sparing. In cases regarded as fat infiltration, score changes were more prominent at FS T1 images than FS T2 images(p=0.0002). In cases regarded as fat sparing, score changes were more prominent at FS T2 images than FS T1 images(p=0.042). CONCLUSION: Breath-hold fast T1 and T2-weighted MR imaging with and without chemical saturation pre-pulse may be sufficient for characterization of regional fatty changes in the different ferential diagnosis of focal hepatic lesion found at sonography.

Angiolymphoid hyperplasia with eosinophilia(ALHE) is a benign, uncommon disorder of unknown etiology, that usually appears as intradermal, subcutaneous or both, red to brown, papules and/or nodules, usually located on the head and neck of young adults and is often associated with peripheral blood eosinophilia. Extracutaneous lesions are rare. We report a 25 year-old male patient who had pruritic dark brown colored, moderately firm nodules and plaques on the left postauricular area, that histopathologically showed features of ALHE. He was treated with triamcinolone acetonide intralesional injection successfully.

Lymphoepithelioma-like carcinonma of the skin(LELCS) is a rare tumor with a microscopic resemblance to lymphoepitheliomatous tumors of the nasopharynx. Less than 100 examples of LELCS are having been reported since its initial description in 1988. Elderly patient are preferentially affected, and the skin of the head and neck is the principal location for this neoplasm. We report a 70 year-old male patient who had brownish colored, moderately firm nodule on the left malar area of the face. Histopathologically, the nodule showed features of LELCS and he was treated with excision and local flap coverage.

Henoch-Scholein Purpura(HSP) is a syndrome characterized by nonthrombocytopenic purpura accompanied by a arthralgia, gastrointestinal symptom, or renal involvement. This report describes a 13-year-old boy with hemorrhaic bullous HSP followed by cellulitis as a complication. This unusual cutaneous manifestation of HSP may be a source of diagnostic confusion, but it does not appear to have prognostic implication.

PURPOSE: This study was conducted to evaluate clinical validity of a zirconia full-coverage crown by comparing zirconia's wear capacity over antagonistic teeth with that of feldspathic dental porcelain. MATERIALS AND METHODS: The subject groups were divided into three groups: the polished feldspathic dental porcelain group (Group 1), the polished zirconia group (Group 2), and the polished zirconia with glazing group (Group 3). Twenty specimens were prepared from each group. Each procedure such as plasticity, condensation, and glazing was conducted according to the manufacturer's manual. A wear test was conducted with 240,000 chewing cycles using a dual-axis chewing simulator. The degree of wear of the antagonistic teeth was calculated by measuring the volume loss using a three-dimensional profiling system and ANSUR 3D software. The statistical significance of the measured degree of wear was tested with a significant level of 5% using one-way ANOVA and the Tukey test. RESULTS: The degrees of wear of the antagonistic teeth were 0.119 +/- 0.059 mm3 in Group 1, 0.078 +/- 0.063 mm3 in Group 3, and 0.031 +/- 0.033 mm3 in Group 2. Statistical significance was found between Group 1 and Groups 2 and between Group 2 and 3, whereas no statistical significance was found between Group 1 and Group 3. CONCLUSION: Despite the limitations of this study on the evaluation of antagonistic teeth wear, the degree of antagonistic tooth wear was less in zirconia than feldspathic dental porcelain, representing that the zirconia may be more beneficial in terms of antagonistic tooth wear.

BACKGROUND: Q-switched lasers have made it possible to remove tattoos without leaving unsightly scars. OBJECTIVE: Tobdetermine the optimal time for permanent makeup removal using Q-switched Nd:YAG and ruby lasers, we compared the degree of removal and associated histological changes following irradiation at different time points. METHODS: Using black ink and a permanent makeup machine, we performed 108 separate permanent makeup applications on rat skin. The 1,064-nm Q-switched Nd:YAG laser (QSNDL) and 694-nm Q-switched ruby laser (QSRL) were used to irradiate the permanent makeup on the day of its application and also 3, 5, 7, 14, and 21 days later. We assessed changes in pigmentation over time at each irradiated site using Mexameter® measurements and skin biopsies. RESULTS: The Mexameter® analysis demonstrated no significant differences in pigment removal among irradiations with QSNDL or QSRL on the day of permanent makeup application or at 3, 5, 7, 14, and 21 days later. Histological analysis demonstrated that permanent makeup pigment migrated from the epidermis to the superficial and mid dermis over time. QSNDL more effectively removed pigment throughout the epidermis and dermis compared to QSRL. CONCLUSION: For maximum pigment removal efficacy, the melanin index results suggest that laser treatment should be performed on the day permanent makeup is applied. However, from the histological perspective, permanent makeup should be removed approximately 1 week later, at which point the crusts have peeled off and the wound repair process is almost complete. In this study, histological analysis suggested the superiority of treatment with QSNDL to that with QSRL.
