BACKGROUND: Chronic cutaneous lupus erythematosus(CCLE) is a well-known disease entity. But there has been no data about its clinical behavior and histopathologic features in Korea. OBJECTIVES: This study was conducted to elucidate the clinical, laboratory, and histopathologic features of CCLE, and the relationship between CCLE and SLE. MATERIALS AND METHODS: We investigated 48 cases of CCLE that visited the department of dermatology at the Seoul National University Hospital from January 1990 to June 1997. Medical records and biopsy slides were reviewed.

OBJECTIVE: This study was designed to define the Korean norm values for the Ricketts analysis. METHODS: In this longitudinal study, lateral cephalograms of 31 subjects with normal occlusion were taken biennially from ages 9-19 years. Cephalometric measurements were performed. Parameters for which the 10-year change did not exceed one standard deviation were defined as unchanged. The means and standard deviations for the measured parameters were determined for each age group. RESULTS: No significant changes in growth were observed in the molar relationship, incisor overjet, incisor overbite, mandibular incisor extrusion, interincisor angle, lower incisor tip (B1) to A point-Pogonion (A-PO) plane, upper incisor tip (A1) to A-PO plane, B1 inclination to A-PO, A1 inclination to A-PO, B1 inclination to Frankfurt plane (FH), convexity, lower facial height, facial axis, maxillary depth, maxillary height, palatal plane to FH, cranial deflection, ramus Xi position, or porion location. Continual changes over the 10 years of growth were observed in the maxillary first molar distal position to pterygoid true vertical plane, facial depth, mandibular plane to FH, anterior cranial length, mandibular arc, and corpus length. CONCLUSIONS: Clinicians can apply the Korean norms at age 9 as determined in this study when using the Ricketts analysis. The patient's age at the beginning of treatment and their sex should be taken into consideration when drawing visual treatment objectives.

PURPOSE: To investigate which spectral domain optical coherence tomography (SD-OCT) findings predict visual outcome after anti-vascular endothelial growth factor (VEGF) treatment in neovascular age-related macular degeneration (NV-AMD). METHODS: We reviewed the medical records of patients with treatment-naive NV-AMD who underwent three or more consecutive anti-VEGF injections. The patients were divided into three groups according to their changes of visual acuity (VA); improved (group I), static (group S), or worsened (group W). We assessed the incidences and values of all available SD-OCT findings of these groups, compared these findings between the three groups and compared the initial values with the post-treatment values. RESULTS: Better initial VA and longer external limiting membrane (ELM) length were associated with less change in VA after anti-VEGF treatment. The initial VA was mildly correlated with initial photoreceptor inner and outer segment junction (IS/OS) length and initial ELM length. The final VA was also mildly correlated with the final IS/OS length and the final ELM length. VA was significantly changed after anti-VEGF treatment in groups W and I. With regard to incidence, disruption of the IS/OS (IS/OS-D), disruption of the ELM (ELM-D) and ELM length differed significantly between the three groups, particularly ELM-D. The incidences of IS/OS-D and ELM-D in group I were significantly lower than those in groups S and W, and those in group S were also lower than those in group W. The ELM length in group I was significantly longer than it was in groups S and W, and the ELM length in group S was longer than that for group W. However, these three findings did not change after the anti-VEGF treatment. CONCLUSIONS: Initial IS/OS-D, ELM length and particularly ELM-D can be useful predictors of the visual outcome after anti-VEGF treatment in NV-AMD patients.

BACKGROUND: Congenital hypotrichosis is a non-specific, descriptive term for structural abnormalities of hairs showing variable clinical features. We recently have encountered a group of eleven patients exhibiting abnormal hairs showing similar patterns. OBJECTIVES: Our purpose was to clarify the entity of this structural hair disorder. METHODS: Dermatologic examination with routine histopathology, trichograms along with scanning electron-microscopic examination and laboratory studies were undertaken. RESULTS: All cases except one were female, and hair abnormalities had developed at birth or within a year. Diffuse distribution of thin, sparse, soft and hypopigmented hairs were noticed. On hair mounts, four patients showed tapering of roots. The majority of the patients exhibited cuticular changes, as well as pitting and longitudinal axial twisting by scanning electron-microscopic examination; one case demonstrated trichorrhexis nodosa, and another, trans-verse fracture. CONCLUSION: Although our cases bear some similar points with woolly hair, some differences were noted between this type of congenital hypotrichosis and other previously described syndromes.

10.The Graft Outcomes of Living Donor Renal Transplantation according to Gender, Age, and BMI Matching between Donors and Recipients.
The Journal of the Korean Society for Transplantation 2010;24(3):204-209
BACKGROUND: Despite significant advances in immunosuppression, supportive therapies, and operative skills, several factors still compromise long-term graft survival of patients who undergo renal transplantation. This study was designed to evaluate the risk factors influencing graft outcomes of living donor renal transplantation. We matched the recipient and donor age, gender, and body mass index (BMI). METHODS: A total of 527 living renal transplantations were evaluated. The patients were divided into matching groups by donor and recipient age; group 1 (50< or =/; 2, 50< or =/<50; 3, <50/50< or =; 4, <50/<50), gender (A, female/female; B, female/male; C, male/female; D, male/male), and BMI ratio (recipient/donor) (I, <0.8; II, 0.8< or =/<1.3; III, 1.3< or =). We compared 1, 3, 5, and 10 year graft survival and analyzed the donor and recipient variables of age, HLA matching, and acute rejection. RESULTS: The risk factors affecting long-term graft survival were recipient gender, acute rejection rate, and HLA-AB matching. In the groups divided according to donor and recipient age, no statistical difference was observed among the groups, but the 3-5 yr graft survival of group 1 (94.1/86.9%) was much higher than group 2 (86.5/75.6%). In the groups divided according to donor and recipient gender, graft survival in group C was higher than that in the other groups. No statistical difference in acute rejection or graft survival were observed in the groups with different BMI ratios. CONCLUSIONS: Meticulous preoperative donor and recipient matching for living renal transplantation may improve graft survival and expand the donor and recipient pool.
