( Jiyun Jang ),( Myeonghyeon Yang ),( Joonhee Kim ),( Minsoo Jang Keesuck Suh ) 대한피부과학회 2017 대한피부과학회 학술발표대회집 Vol.69 No.2

Background: Lichenoid purpura (LP) is a variant of pigmented purpuric dermatosis (PPD) that is characterized by rust macules or papules mainly on the legs and histologically by a dense, band-like dermal inflammatory cell infiltrate with extravasated red blood cells. Recent data suggests that LP may be a precursor of mycosis fungoides (MF), with similar histologic features. Medium-dose ultraviolet A-1 (UVA-1) is an effective treatment option for MF. From this perspective, medium-dose UVA-1 phototherapy may be an effective treatment for LP. Objectives: To investigate the efficacy of medium-dose UVA-1 phototherapy on LP. Methods: This study was conducted on 11 patients diagnosed with LP at one institution. Medium-dose (65J/㎠) regimens of UVA-1 were employed. The therapeutic efficacy was assessed according to the clinical examination before and after the last treatment. Results: The patients were between 26 and 77 years of age with mean age of 49.1 years. All the patients developed gold to brownish papules, or plaques on the lower extremities and one patient also developed skin lesions on the abdomen. Among the 11 patients, two patients achieved complete remission and nine patients achieved partial remission. Mean numbers of irradiations of UVA-1 was 14.5 sessions, and no recurrence was observed during the mean follow-up period of 26.4 months. Conclusion: Medium-dose UVA-1 phototherapy may be a safe and effective treatment modality for LP.

( Jiyun Jang ),( Seolhwa Seong ),( Myeonghyeon Yang ),( Jongbin Park ),( Minsoo Jang ),( Keesuck Suh ) 대한피부과학회 2018 대한피부과학회 학술발표대회집 Vol.70 No.2

Background: Rosacea is a chronic inflammatory disease that affects central portion of the face. Mast cell has been suggested to mediate the cathelicidin-induced inflammation of rosacea. Therefore, mast cell stabilizer may be effective in treating rosacea. To date, there is no previous study evaluating efficacy of oral mast cell stabilizer in rosacea. Objectives: To compare the efficacy of oral minocycline and oral minocycline plus ketotefen in rosacea. Methods: 24 patients diagnosed with rosacea were divided into two groups: 11 patients treated with oral minocycline (100-200mg/day) (minocycline group); 13 patients treated with oral minocycline (100-200mg/day) plus ketotifen (2mg/day) (combination group). The therapeutic efficacy was assessed according to investigator’s global assessment (IGA) and clinician’s erythema assessment (CEA) at baseline, after 4, 8, and 12 weeks. Results: At 12 weeks, the mean IGA score was reduced from 3.69 to 1.27 in minocycline group, and from 3.73 to 0.92 in combination group. IGA success (IGA rating of clear or minimal) was achieved in a greater proportion in combination group (76.9%) compared with minocycline group (63.6%). At 12 weeks, the mean change from baseline in CEA score was -1.7 and -1.45 for the combination and minocycline groups, respectively. Conclusion: Oral minocycline plus ketotifen combination therapy can be more effective treatment for rosacea compared with oral minocycline monotherapy.

This paper presents a novel algorithm for searching evacuation paths in indoor disaster environments. The proposed method significantly improves the time complexity to find the paths to the evacuation exit by introducing a light-weight Disaster Evacuation Graph (DEG) for a building in terms of the size of the graph. With the DEG, the method also considers load balancing and bottleneck capacity of the paths to the evacuation exit simultaneously. The behavior of the algorithm consists of two phases: horizontal tiering (HT) and vertical tiering (VT). The HT phase finds a possible optimal path from anywhere of a specific floor to the evacuation stairs of the floor. Thus, after finishing the HT phases of all floors in parallel the VT phase begins to integrate all results from the previous HT phases to determine a evacuation path from anywhere of a floor to the safety zone of the building that could be the entrance or the roof of the building. It should be noted that the path produced by the algorithm. And, in order to define the range of graph to process, tiering scheme is used. In order to test the performance of the method, computing times and evacuation times are compared to the existing path searching algorithms. The result shows the proposed method is better than the existing algorithms in terms of the computing time and evacuation time. It is useful in a large-scale building to find the evacuation routes for evacuees quickly

( Jiyun Jang ),( Seolhwa Seong ),( Myeonghyeon Yang ),( Jongbin Park ),( Minsoo Jang ),( Keesuck Suh ) 대한피부과학회 2018 대한피부과학회 학술발표대회집 Vol.70 No.2

Background: Mycosis fungoides palmaris et plantaris (MFPP) is a variant of mycosis fungoides (MF) that presents primarily on the palms and soles, which is often refractory to conventional therapy. Alitretinoin is an endogenous panagonist binding to retinoid receptors and promoting the anti-proliferative, immune-modulating, and pro-apoptotic effects. From this perspective, oral alitretinoin may be effective to MFPP as in the MF, however, there is no previous case study. We present a retrospective review of MFPP treated with oral alitretinoin. Objectives: To investigate the efficacy and safety of oral alitretinoin in MFPP. Methods: This study was conducted on 10 patients histopathologically diagnosed as MFPP. The patients were treated with oral alitretinoin (30mg/day). The therapeutic efficacy was assessed according to physician’s global assessment (PGA) and modified total lesion symptom score (mTLSS) at baseline and after 12 weeks. Results: The proportion of clinical response defined as PGA of clear or almost clear was 70% (7/10). The mean mTLSS was significantly decreased from 10.5 (baseline) to 3.2 (after 12 weeks), representing a 69.5% of reduction. Half of the patients experienced side effects such as headache (20%), elevated serum triglyceride (20%), and dry mouth (10%), however, there were no serious events leading to withdrawal. Conclusion: Oral alitretinoin can be a well-tolerated and effective alternative treatment for MFPP.

( Jiyun Jang ),( Myeonghyeon Yang ),( Joonhee Kim ),( Minsoo Jang ),( Keesuck Suh ) 대한피부과학회 2017 대한피부과학회 학술발표대회집 Vol.69 No.2

Background: Atopic dermatitis (AD) is a chronic, inflammatory skin disease characterized by pruritus and a chronic course of exacerbations and remissions. High-dose ultraviolet A-1 (UVA-1) phototherapy has been shown to be effective in the treatment of acute exacerbated AD, however, there was no previous case study in Asians. We present a retrospective review of our experiences with high-dose UVA-1 phototherapy. Objectives: To investigate the efficacy of high-dose UVA-1 phototherapy on acute exacerbated AD. Methods: This study was conducted on 11 patients with acute exacerbation of AD. High-dose (100J/㎠) regimens of UVA-1 therapy were employed. The therapeutic effectiveness was assessed according to the clinical examination before and after 5th, 10th, and last sessions of treatment. Results: The patients were between 7 and 29 years of age with mean age of 19.2 years. The SCORAD index (scoring of AD) of 11 patients were between 41 and 89.5 with mean score of 64.2. Among the 11 patients, seven patients showed complete remission and four patients showed partial remission. The mean SCORAD index was reduced from 64.2 (before treatment) to 23.3 (after 10th session of treatment). Mean numbers of irradiations with UVA-1 was 10.5 sessions, and no recurrence was observed during the mean follow-up period of nine months. Conclusion: High-dose UVA-1 phototherapy can be a well-tolerated and effective alternative treatment for acute exacerbated AD.
