In full-thickness defects of the nasal alar rim, to achieve projection and maintain airway patency, cartilage graft is frequently needed. However, cartilage graft presents a challenge in considerations such as appropriate donor site, skeletal shape and size, and healing of the donor area. To avoid these demerits, we tried primary closure of alar rim defects by also making the contralateral normal ala smaller. We treated two patients who had a full-thickness nasal alar defect after tumor excision. Cartilage graft was considered for the reconstruction. However, their alar rims were overly curved and their nostril openings were large. To utilize their nasal shape, we did primary closure of the defect rather than cartilage graft, and then downsized the contralateral nasal ala by means of wedge resection to make the alae symmetric. Both patients were satisfied with their aesthetic results, which showed a smaller nostril and nearly straight alar rims. Moreover, functionally, there was no discomfort during breathing in both patients. We propose our idea as one of the reconstruction options for nasal alar defects. It is a simple and easy-to-perform procedure, in addition to enhancing the nasal contour. This method would be useful for patients with a large nostril and an overly curved alar rim.

Bortezomib (Velcade(R)) is proteasome inhibitor that is used as a first-line therapy for multiple myeloma. It can cause gastrointestinal, hematologic, and neuromuscular side effects, and a cutaneous reaction is one of its common adverse reactions. To date, several bortezomib-induced cutaneous adverse reactions have been reported, including folliculitis-like rash, pruriginous rash, purpuric rash, mouth swelling, stomatitis-mucositis, edema in the lower limbs, telogen effluvium, and vasculitis. In the Korean literature, only one case of vasculitis has been reported earlier. Two patients have presented with multiple plaques on the trunk at our clinic. The lesions developed several days after bortezomib chemotherapy, and disappeared spontaneously in about 1 week. Herein, we report bortezomib-induced drug eruption presenting as multiple plaques on the trunk with a review of the relevant literature.

Background: Pemphigus is an autoimmune blistering disease characterized by the production of autoantibodies against desmosomal proteins. Owing to its high mortality rate, prompt and accurate diagnosis of pemphigus is crucial. Objective: To determine the positivity rates of immunoblotting in patients diagnosed with pemphigus using clinical, histopathological, direct immunofluorescence (DIF), and enzyme-linked immunosorbent assay (ELISA). Methods: We retrospectively evaluated 84 patients diagnosed with pemphigus between 2001 and 2021 at the Chonnam National University Hospital in Gwangju, Korea. Results: Among the 55 patients with pemphigus vulgaris included in the immunoblotting study, 46 (83.6%) exhibited positive findings for the 130 kDa band. Of the 29 patients with pemphigus foliaceus, 17 (58.6%) showed positive findings for the 160 kDa band. In cases where autoantibodies were difficult to detect with negative DIF and ELISA results, immunoblotting aided in the diagnosis of 18.2% of pemphigus vulgaris cases and 6.9% of pemphigus foliaceus cases. Conclusion Immunoblotting can serve as an alternative diagnostic method for patients with mild-to-moderate disease or those who have undergone treatment, especially when DIF or ELISA tests yield negative or atypical results.

Morgellons disease is a rare disease with unknown etiology. Herein, we report the first case of Morgellons disease in Korea. A 30-year-old woman presented with a 2-month history of pruritic erythematous patches and erosions on the arms, hands, and chin. She insisted that she had fiber-like materials under her skin, which she had observed through a magnifying device. We performed skin biopsy, and observed a fiber extruding from the dermal side of the specimen. Histopathological examination showed only mild lymphocytic infiltration, and failed to reveal evidence of any microorganism. The polymerase chain reaction for Borrelia burgdorferi was negative in her serum.

BACKGROUND: Elastic recoil contributes to the residual lumen reduction immediately after PTCA. We evaluated the factors to influence on immediate elastic recoil after the successful PTCA. METHODS: 88 patients(96 lesions) were studied by quantitative angiography. Angiograms were obtained in two identical near orthogonal projection before PTCA and immediately after the last balloon deflation. RESULTS: Immediately after PTCA, minimal luminal diameter increased from 0.7+/-0.6mm to 1.9+/-0.6mm and percent diameter stenosis was reduced from 77+/-20 to 34+/-21%. The calculated mean elastic recoil was 0.5+/-0.7mm in diameter and % elastic recoils were lesser both in calcified(3+/-23 vs 23+/-24%, p=0.04) and thrombotic(9+/-20 vs 23+/-35%, p=0.02) lesions. The elastic recoil increased significantly according to the inflation diameter of balloon(r=0.32, p<0.01. No significant correlation between the immediate elastic recoil and age, sex, risk factors, eccentricity and lesion length was shown. CONCLUSION: The elastic recoil immediately after a successful PTCA was dependent on the existance of calcium and thrombus on the target lesion and on the balloon size at the maximal inflation.
