Background: Nasal defects repairing is one of the most challenging aspects of cutaneous reconstruction. Melolabial interpolation flap (MIF) should be considered in one of the available surgical options to provide for the best postoperative outcome. Objectives: The aim of this study was to evaluate the effectiveness and cosmetic outcomes of MIF for the reconstruction of nasal defects after basal cell carcinoma (BCC) excision. Methods: Between 2003 and 2013, 26 patients were received by MIF for reconstruction of nasal defects of BCC after Mohs surgery or wide excision. We reviewed surgical techniques, complications, and final cosmetic results. Post-operative results were assessed with serial clinical photographs, physicians` objective records and patients` subjective records. Results: The size of surgical defects was ranged from 0.5 to 3.0 cm in their greatest diameter. Most of the patients involved more than 2 cosmetic subunits after excision. Frequent involved sites were nasal tip and nasal ala. There were no significant complications. And the cosmetic outcomes were considered as good or excellent in most of patients. Conclusion: MIF is regarded as the recommended technique for the repair of mid to large nasal defects, especially involving nasal ala, providing excellent cosmetic results with few complications.

Lymphorrhea is a rare but potentially severe complication that occurs after various surgical procedures. Untreated lymphorrhea may lead to wound dehiscence, infection, and prolonged hospital stay. Currently, there is no standard effective treatment. Early management usually includes leg elevation, drainage, and pressure dressing. However, these methods are associated with prolonged recovery and high recurrence rates. We report a case of lymphorrhea from a calf wound after endoscopic great saphenous vein (GSV) harvesting for coronary artery bypass grafting (CABG). The patient presented with intractable oozing from the postoperative wound on the right calf. Lymphorrhea persisted for 6 weeks despite negative-pressure wound therapy with a long-acting somatostatin. We performed unilateral pedal lymphangiography that confirmed wound lymphorrhea, followed by glue embolization. No recurrence was observed after 8 months of follow-up. This case report demonstrates the successful use of lymphangiography with glue embolization in the control of lymphorrhea after GSV harvesting for CABG.

The surface roughness in centerless grinding is mainly affected by the many process parameters. For improving the surface roughness, the control of grinding parameters is very important. This paper deals with the analysis of the process parameters such as height of centers, tilting angle of the regulating wheel with respect to grinding wheel, rotation speed of regulating wheel, which are developed based on design of experiments such as factorial design. The investigation can enhance the surface roughness of ferrule. Finally, we have verified improved results of the optimized conditions.

Background: Psoriasis is a chronic inflammatory dermatosis and various topical or systemic drugs should be selected depending on severity. Objective: The purpose of this study was to compare the efficacy and adverse reactions of methotrexate (MTX) and cyclosporine A (CsA) in the treatment of moderate-to-severe plaque psoriasis. Methods: A retrospective analysis of the therapeutic efficacy of MTX and CsA was performed on 81 patients (MTX 30, CsA; 51) with moderate-to-severe plaque psoriasis. The MTX treatment was administered in weekly doses of 2.5 mg-7.5 mg up to 3 times every 12 hours. The CsA treatment was administered at daily doses of 1.5-5 mg/kg. Regular follow-up and laboratory tests were performed to evaluate the efficacy and adverse reactions of MTX and CsA. Results: Reach to PASI 50 was observed in 93% of patients in the MTX-treated group with an average-time of 4.8 weeks, and in 70% of patients in the CsA-treated group with an average-time of 7.1 weeks. Among nine patients who were switched from MTX to CsA, 55.6% had improved with CsA treatment in 6.6 weeks. In contrast, among the 22 patients who were switched from CsA to MTX, 77.3% had improved with MTX treatment in 5.4 weeks. Adverse reactions to MTX and CsA were observed in 40% and 25% of the treated patients, respectively, most of which were mild and transient. Average relapse-time in patients improved by the drugs was 20.4 weeks in the MTX group and 15.4 weeks in the CsA group. Conclusion: Treatment with MTX is found to be a more effective systemic agent than CsA in both therapeutic response and length of relapse-free periods.eriod. (Korean J Dermatol 2014;52(9):615∼621)
