Psoriasis vulgaris is one of the most common skin diseases in the world, which is recognized as an autoimmune disease that is caused by genetic and environmental factors. Plaque, guttate, pustular form, and psoriatic erythroderma are known as classical feature of psoriasis with tendency as generalized or sporadic appearance. There are some cases of uncommon forms in the shape and distribution, as nevoid and linear psoriasis. Linear psoriasis is a rare entity and thought as a variant of psoriasis, but its existence is still in debate. Herein, we report an interesting case of 19-year old Korean man with psoriasis, occurring on the right arm, following the line of Blaschko in a linear form.

PURPOSE: To assess in monocular amblyopia patients the effectiveness of solitary part-time occlusion in overcoming the disadvantages of full-time occlusion. METHODS: Forty monocular amblyopia patients, aged from 3 to 8 years, who had more than 0.7 in visual acuity of the sound eye and more than 2 lines in binocular difference of visual acuity, were treated only with part-time occlusion for 6 hours per day. Patients were classified into three age groups: 3~4 years, 5~6 years, and 7~8 years. We compared best corrected visual acuity (BCVA) and binocular difference of visual acuity, before and after 6-hour patching. We also compared the difference at the end of patching with that at the last follow-up visit. RESULTS: BCVA and binocular difference of visual acuity were significantly improved (p<0.001). Average duration of occlusion was 15.4 +/- 13.0 months (9~55months). Thirty-two of 40 patients had less than 2 lines of binocular difference of visual acuity after patching. Visual acuity of each age group was also significantly improved but there was no difference in the degree of improvement or the duration of occlusion among the three age groups. It was also maintained well until the last follow-up visit. CONCLUSIONS: For the treatment of amblyopia patients, solitary, 6-hour, part-time occlusion revealed effective improvement of BCVA and good maintenance of the improvement.

Papular xanthoma is a normolipemic xanthomatosis, characterized by nonconfluent papular to papulonodular eruptions on the face, trunk, extremities and occasionally mucous membranes. Histologically, there was an infiltration of foamy histiocytes and Touton type giant cells in the dermis without inflammatory cells or a pure histiocytic component. But, occasional lymphocytes were interspersed between the foamy macrophage. No systemic involvement could be found and the blood lipid profiles were normal. We report a case of papular xanthoma in a 30-year-old man with typical clinical, histopathologic findings.

PURPOSE: The objective of this study was to obtain improved susceptibility weighted images (SWI) of the cervical spinal cord using respiratory-induced artifact compensation. MATERIALS AND METHODS: The artifact from B0 fluctuations by respiration could be compensated using a double navigator echo approach. The two navigators were inserted in an SWI sequence before and after the image readouts. The B0 fluctuation was measured by each navigator echoes, and the inverse of the fluctuation was applied to eliminate the artifact from fluctuation. The degree of compensation was quantified using a quality index (QI) term for compensated imaging using each navigator. Also, the effect of compensation was analyzed according to the position of the spinal cord using QI values. RESULTS: Compensation using navigator echo gave the improved visualization of SWI in cervical spinal cord compared to non-compensated images. Before compensation, images were influenced by artificial noise from motion in both the superior (QI = 0.031) and inferior (QI = 0.043) regions. In most parts of the superior regions, the second navigator resulted in better quality (QI = 0.024, P < 0.01) compared to the first navigator, but in the inferior regions the first navigator showed better quality (QI = 0.033, P < 0.01) after correction. CONCLUSION: Motion compensation using a double navigator method can increase the improvement of the SWI in the cervical spinal cord. The proposed method makes SWI a useful tool for the diagnosis of spinal cord injury by reducing respiratory-induced artifact.

Primary cutaneous marginal zone B-cell lymphoma, known as the cutaneous counterpart of mucosa-associated lymphatic tissue lymphoma (MALT lymphoma), is the most frequent of the primary cutaneous B-cell lymphoma. It is one of the low-grade lymphomas of B-cell type, which has an excellent prognosis with indolent behavior, despite frequent cutaneous recurrences. Histologically, cutaneous marginal zone B-cell lymphoma is composed of polymorphous infiltrate that includes centrocyte-like, centroblast-like, monocytoid, and lymphoplasmacytoid lymphocytes. We present two cases of primary cutaneous marginal zone B-cell lymphoma. A 48-year-old woman visited the dermatologic clinic with 1.5x1.5 cm sized, skin colored, palpable nodule on the left temporal area and a 26-year-old man visited the dermatologic clinic with 1x1 cm sized erythematous nodule on the nose. Both of them showed compatible histologic findings of marginal zone B-cell lymphoma and had no past medical history and no evidence of metastasis on PET-CT and bone marrow biopsy. The woman was treated with radiation treatment after excision and the man was treated with radiation treatment alone. Follow-up indicates that 1 year after treatment there is no evidence of recurrence.

OBJECTIVE: Bupropion is an antidepressant with proven efficacy for smoking cessation, however the response rate is some limited. With this background, the authors investigated the difference of early bupropion response in smoking cessation according to individual genetic polymorphism and temperamental characteristics. METHOD: Subjects were 113 Korean male volunteers who were nicotine dependent and wanted to quit smoking. Authors compared 6 candidate genes (DRD2, DRD4, dopamine transporter, norepinephrine transporter, serotonin transporter, COMT), and Temperament Character Inventory (TCI) between response group and non-response group after 3 weeks bupropion treatment. RESULT: Among 6 candidate genes, DRD2 homozygotes (A2/A2+A1/A1), COMT H/H genotype and H allele carriers showed high rate of smoking cessation by bupropion. NET-8 GG genotype and G allele carriers showed low rate of smoking cessation by bupropion. Persistence score in TCI was significant between two groups. CONCLUSION: DRD2, COMT, NET-8 genetic polymorphisms and some temperamental characteristics could predict success of smoking cessation by early treatment response of bupropion.

PURPOSE: The aim of this study was to investigate the clinical and radiological incidence of parastomal hernia. METHODS: We reviewed, retrospectively, 83 patients with end colostomy operated on from January 2003 to June 2009 at Ajou University hospital. Age, sex, surgical procedure type, body mass index (weight/length2), stoma size, and respiratory co-morbidity were documented. We compared the incidence of radiological and clinical parastomal hernia. RESULTS: There were 47 males (56.6%) and 36 females (43.4%). During an overall median follow-up of 30 months (range, 6 to 45 months), 24 patients (28.9%) developed a radiological parastomal hernia postoperatively and 20 patients (24.1%) presented clinical symptoms. Using computed tomography (CT) classification, the groups were as follows: type 0 (40, 48.2%), type Ia (19, 22.9%), type Ib (8, 9.6%), type II (4, 4.8%) and type III (12, 14.5%), with 63 asymptomatic patients and 20 symptomatic patients. The aperture size was significantly different between symptomatic and asymptomatic patients (76.45 mm vs. 49.41 mm; P = 0.000). There was a significant correlation between aperture size and the radiological type (P = 0.003). CONCLUSION: This study showed the incidence of radiological parastomal hernia is acceptable compared to previous studies. CT classification may be useful to evaluate parastomal hernia.
