Background: Bullous pemphigoid (BP) is an autoimmune subepidermal blistering disease characterized by tissue- bound and circulating autoantibodies directed against BP180 and/or BP230 antigens. Various inflammatory cells are involved in the development of blister in BP. Objective: The aim of this study was to evaluate the correlation between peripheral leukocyte counts and BP severity. Methods: We retrospectively included 60 patients with BP, who had not been treated with systemic steroid at the

Angiokeratoma is a rare vascular malformation of the upper dermis that presents clinically as deep red to blue-black in color and tends to take a diverse configuration without self-limiting. Here, we reported dermoscopic findings by two cases of angiokeratoma; solitary angiokeratoma and angiokeratoma circumscriptum. A 24-year-old male presented with a 2-months history of 5 mm sized black colored papule on the right buttock. A dermoscopic pattern characterized by red and dark lacunae, whitish vei

Background: Radiographic modalities have been commonly used to evaluate pectus carinatum (PC), and compressive orthotic bracing is the most widely accepted treatment method. The aim of this study was to determine the efficacy of 3-dimensional (3D) body surface scanning as an alternative modality for the evaluation of PC. \n\nMethods: The medical records of 63 patients with PC who were treated with compressive orthotic bracing therapy between July 2017 and February 2019 were retrospectively analy

We reported a multicenter Asian case series with the novel FET hybrid prosthesis demonstrating the feasibility and safety of promising initial clinical outcomes. The technique of circumferential reinforcement of vascular anastomosis for hemostasis may be one of the methods for lowering the rates of re-sternotomy for hemostasis, and proper surgical or transfusion strategies would overcome the excessive oozing of the prosthesis. Long-term follow-up is required for further evaluation of aortic path

OBJECTIVES: In this cohort study, we aimed to assess the 1-year clinical outcomes of using the E-vita Open NEO™ hybrid prosthesis for total arch replacement with frozen elephant trunk (FET) to repair extensive aortic pathologies. METHODS: We reviewed individuals who underwent thoracic aortic surgery between April 2021 and March 2023 from the Gangnam Severance Aortic Registry. Exclusion criteria included ascending aortic replacement, 1 or 2 partial arch replacement, descending aortic replacement

Minimally invasive cryoablation is often considered for lung tumor patients with high surgical risk or inoperable metastatic lung tumors. Cryoablation is a type of thermal percutaneous ablation in which argon and helium gases are delivered via a cryoprobe to induce tissue freezing and necrosis. We report the case of a 23-year-old woman who had suffered from multiple pulmonary endometriosis with frequent intermittent hemoptysis during menstruation for 6 years prior to her visit. She was treated w

Objectives: To date, there is no consensual definition of what constitutes a postoperative recurrence of primary spontaneous pneumothorax (PSP), despite there being many studies reporting a high incidence of recurrence. This study aims to describe the long-term recurrence rates of pneumothorax and to suggest a possible way to differentiate recurrence events based on temporal patterns. Methods: This single-center study retrospectively evaluated all postoperative recurrence of PSP from January 200

Background\nSevoflurane is widely used to ambulatory pediatric anesthesia. But, sevoflurane is associated with a high incidence of emergence agitation in children. In this study, we examined the effect of single intravenous lidocaine prior to extubation on emergence agitation and cough in children undergoing adenotonsillectomy.\n\nMethods\nAll patients received a standardized anesthetic regimen with 2-3% sevoflurane in 50% O2/N2O after anesthetic induction with intravenous glycopyrrolate 0.004 m

Background: Acral melanoma occurs on glabrous skin or the nail apparatus and is distinct from ultraviolet-related melanoma due to differing genetic alteration patterns. Although the pathogenesis of acral melanoma is not well understood, mechanical stress is thought to induce acral melanoma. The incidence of gene mutation and promoter methylation has been reported in tumors from acral melanoma; however, an association between genetic/epigenetic alterations and mechanical stress in acral melanoma

Background: Sebaceous neoplasm is a rare subgroup of appendageal tumors that differentiate towards sebaceous adnexal structures of the skin and are known to be associated with visceral malignancy. Objective: We aimed to analyze and compare the clinical data including the past history of associated visceral malignancy in patients with sebaceous carcinoma (SC) and benign sebaceous neoplasms (BSN), such as sebaceous adenomas and sebaceomas. Methods: We retrospectively reviewed the cases of consecut

Chondroid syringoma is a rare epithelial tumor with an adnexal gland origin, and it clinically presents as a slowly growing benign nodule. A 57-year-old woman presented with a 1-year history of 1×1 cm subcutaneous firm nodule on her scalp. The biopsy specimen showed a basophilic stroma and small tubular structures that were lined by a single layer of epithelium, small groups of epithelial cells and solitary epithelial cells. The tumor cells showed positive immunoreactivity for S-100. Herein, we

An ingrown toenail, which causes pain especially with secondary infection, and is one of the most common diseases of toenails. It becomes difficult for a patient to walk and this subsequently impairs the quality of life. Surgical procedures, including total or partial excision of the nail bed, phenolization and the carbon dioxide laser matricectomy method, are commonly performed to treat this problem. The disadvantages of these methods include their complexity, the pain, the time required to do

서 론건강한 성인 1,2) 및 소아에서 3,4) sevoflurane (SEVO)은 QTc 간격을 연장시키는 효과가 있으며, 3-6) 한편 선천성 long QT syndrome이 있는 환자에서도 SEVO가 QT 간격을 더욱 연장 시키는 것이 보고되었다. 5)기니 픽 심실근 세포에서 Park 등 6) 및 Shibata 등은 7) SEVO가 활동전위 기간을 연장시키는 효과가 있음을 관찰하였다.심전도상에서 QT 간격은 심실 근 세포의 활동전위 기간과 일치한다는 사실을 두고 볼 때 Park 등 6) 및 Shibata 등의 결과는 7) 임상에서의 심전도 결과 와 일치한다고 하겠다.활동전위의 연장과 관련된 전기생리 학적인 연구로서 Park 등은 6) 기니 픽 심실근 세포에서 SEVO 가 투여 농도에 비례하여 delayed outward K + current (Ik)를 억제시키나, inwardly rectifying K + current (IkI)에는 영향이 없는 점으로 보아 SEVO의 활동전위

Total arch replacement for aortic dissection is traditionally associated with high mortality and morbidity rates. Here, we share our strategies for improving surgical outcomes such as Y incision, unilateral antegrade cerebral perfusion, Teflon felt neo-media formation, and reinforcement of the anastomosis site.
