Neurological complications attributed to coronavirus disease-19 (COVID-19) infection have been reported including acute disseminated encephalomyelitis, Guillain-Barré syndrome, and so on. Herein, we report a 49-year-old woman presented with acute encephalopathy and paraplegia simultaneously after COVID-19 infection. Brain magnetic resonance imaging (MRI) showed symmetric hyperintense basal ganglia lesions on T2-weighted imaging. Cerebrospinal fluid pleocytosis, motor axonal neuropathy and enhancement of conus medullaris nerve roots on spine MRI were observed. We treated her with high-dose corticosteroid and intravenous immunoglobulin.

Recently, a novel influenza A (H1N1) has been recognized as the cause of a worldwide respiratory infection outbreak. Although the symptoms of a novel influenza A (H1N1) are usually mild, the disease can cause severe illness and death. A complication of novel influenza A (H1N1) is pneumomediastinum, a rarely reported condition. We report a case of influenza A (H1N1) complicating pneumomediastinum with subcutaneous emphysema, which had initially presented with blood tinged sputum and chest pain. In addition, we demonstrate bronchoalveolar lavage in influenza A (H1N1).

Pneumocephalus after thoracoscopic excision of a mediastinal mass is a very rare complication. It presumably occurs due to dural injury near the spinal root and development of a subsequent subarachnoid-pleural fistula. A 60-year-old woman complained of nausea and headache after thoracoscopic excision of a posterior mediastinal mass. She was diagnosed with pneumocephalus by brain CT and recovered with supportive management.

Acute mesenteric ischemia after cardiac surgery is a serious complication associated with high mortality. Superior mesenteric artery is most commonly affected artery. Acute obstruction of mesenteric artery generally has an unfavorable prognosis because of late diagnosis. The keys to a successful outcome are early diagnosis and appropriate operative intervention. We successfully treated a patient with acute mesenteric ischemia after aortic valve replacement. Therefore, we report a case with a review of articles.

Spontaneous hemothorax vary in cause and are rare for hemothorax induced osteochondroma. Sometimes hemothroax is reported due to osteochondroma induced injury of diaphragm, lung, pericardium, heart, or pleura. We report a patient with diaphragm laceration due to osteochondroma.

Nowadays, it is becoming difficult to secure a transmission line route when a new transmission line is constructed due to social environment and resident complaints. As existing urban areas are expanded and new cities are constructed, the necessity of high-capacity underground power transmission has been increasing because of load concentration in downtown areas. In North America, Europe and Japan, the research has been carried out for 2nd generation gas insulated transmission lines(GIL) which is more environmentally friendly and economical compared to previous GILs. The new GILs have been applied to real power systems from early 2000s. In South Korea, GIL is being considered as a possible solution for replacing 345kV high-capacity overhead transmission lines with underground transmission ones, so KEPCO is planning to develop and apply a new 362kV rated GIL underground transmission lines instead of overhead transmission lines. In this paper, the overvoltage generated at the combined transmission line adapting GIL was reviewed using EMTP.

Unilateral absence of a pulmonary artery (UAPA) is a rare congenital anomaly that may present with various symptoms, depending on the nature and severity of other cardiovascular anomalies. Furthermore, contralateral lung surgery in patients with UAPA is extremely rare, and clinical experience is limited. This report describes a case of surgical treatment of contralateral primary lung cancer in a patient with isolated UAPA. A 56-year-old man was diagnosed with primary lung cancer accompanied by isolated UAPA on the contralateral side. He underwent meticulous cardiorespiratory function tests preoperatively. We performed a right lower lobectomy. Although in the immediate postoperative period, the patient suffered from a mild decline in his respiratory function, he recovered uneventfully. The present case shows that preoperative awareness of UAPA and meticulous perioperative management enable contralateral lung surgery to be performed safely.

The Coronavirus disease 2019 (COVID-19) has rapidly spread across the world and caused a pandemic. It can be transmitted by an infected person or an asymptomatic carrier and is a highly contagious disease. Prevention and early identification of COVID-19 are important to minimize the transmission of COVID-19. Chest computed tomography (CT) has a high sensitivity for detecting COVID-19, but relatively low specificity. Therefore, chest CT may be difficult to distinguish COVID-19 findings from those of other infectious (notably viral types of pneumonia) or noninfectious disease. Pulmonary contusion has also a lot of similarities on chest CT with COVID-19 pneumonia. We present trauma patients with pulmonary contusion whose CT scans showed findings similar to those of COVID-19, and we report our experience in the management of trauma patients during the COVID-19 pandemic.

Objectives In order to the review of the Yoon Gil-Young's theory on the "differentiation of syndromes", we studied on the his method and system of classification on the "differentiation of syndromes". Methods We reviewed on "The Clinical Formula Science Traditional Korean Medicine 東醫臨床方劑學", "A study on the Methodology of Traditional Korean Medicine 東醫學의 方法論硏究" "The theory of SaSang Constitution Medicine 四象體質醫學論". From a connected standpoint with the basic theory and clinical medicine, considered on the Yoon Gil-Young's theory of "differentiation of syndromes". Results Yoon Gil-Young's theory of differentiation of syndromes and treatment was widespread so much that he studied on the learning field of Traditional Korean Mediciine and ingenious as well. The main principles of differentiation of syndromes was summarized the three representative syndrome-complexes; BON-HER(original deficiency syndrome), BON-HAN(orginal cold excess syndrome), BON-YEOL(original heat excess syndrome). And also the three representative syndrome-complexes was previously carried out the details of differentiation of syndromes and assigned represent prescription one by one. Conclusions As the results, Yoon Gil-Young insisted the system of differentiation of syndromes closely connecting with Traditional Korean Medical physiology, pathology, diagnosis and prescriptions. And therefore he was a frontier of the field of Traditional Korean Medicine.

Purpose: Despite the increasing incidence of pediatric Crohn disease (CD) in Korea, data on the characteristics of perianal lesions are scarce. Therefore, we aimed to investigate the characteristics of pediatric CD with accompanying perianal lesions in Korea. Methods: We retrospectively reviewed the medical records of children (age ${\leq}18$ years) with confirmed CD at Gachon University Gil Medical Center between 2000 and 2014. Patients were classified into two groups based on the presence or absence of any perianal lesions including skin tags. Additional analysis was performed according to the presence or absence of perianal perforating lesions. Results: Among the 69 CD children (mean age, 15.4 years) include in the analysis, 54 (78.3%) had a perianal lesion and 29 (42.0%) had a perianal perforating lesion. The median duration of chief complaints was longer in pediatric CD with any accompanying perianal lesions (5.40 months vs. 1.89 months, p=0.02), while there was no difference between pediatric CD with and without perianal perforating lesions (5.48 months vs. 4.02 months, p=0.18). Perianal symptoms preceded gastrointestinal symptoms in 13 of 29 (44.8%) patients with perianal perforating lesions. Conclusions: CD should be suspected in children with perianal lesions, even in circumstances when gastrointestinal symptoms are absent.
