Purpose: Plastic surgeons are responsible for the management of spinal cord injury patients with upper and lower extremity reconstruction, pressure sore, and wounds. Derailment of autonomic nervous systems caused by injury to the spinal cord may result in fatal autonomic dysreflexia. Autonomic dysreflexia is a syndrome of massive imbalance of reflex sympathetic discharge occurring in patients with spinal cord lesion above the splanchnic outflow(T6). It is characterized by a sudden onset and severe increase in blood pressure and is potentially life threatening. The other classic symptoms are headache, chest pain, sweating, and bradycardia. In order to lower the blood pressure, it is important to remove the noxious stimulus for autonomic dysreflexia. If such symptoms last for more than 15 minutes despite conservative interventions, antihypertension drugs are recommended. Methods: In this case study, we report an autonomic dysreflexia case that developed in a 45 year-old tetraplegia patient with sacral pressure sore. When he got bladder irrigation, his blood pressure went up very high and his mentality became stuporous. He was sent to ICU for his blood pressure and mental care. ICU care made his vital sign stabilized and his mentality alert. Results: After the patient underwent proper treatment like inotropic agent, he was transferred to the general ward and his pressure sore on sacral area was coveraged with gluteus maximus myocutaneous advancement flap. Conclusion: If treatment is not effective, the patients have to undergo sudden, severe hypertension, which can cause stroke or death. To provide safe and effective care, plastic surgeons should be able to recognize and treat autonomic dysreflexia.

Purpose: To report a rare case of concealed penis that was aggravated by circumcision and simple way of treatment using skin flap. The concealed penis is a primarily pediatric disease and is usually treated by urologists. The plastic surgeons tend to see these patients when it become secondary deformation or in conjoinment with other specialties. In such situation, the plastic surgeons do not have many experiences.Methods: A 3-year-old boy was admitted with aggravated concealed penis after circumcision in congenital webbed penis. Patient had been operated with scar revision and skin flap and peri operative antibiotics.Results: The patient recovered well without any complication such as infection, hematoma and necrosis of flap. Patient was discharged POD#7 with remaining sutures. Patient was followed up for 7 months and he has no sign of erectile dysfunction, voiding dysfunction and evidence of inflammation of the urinary system.Conclusion: We experienced a case of concealed penis that was aggravated from aggressive circumcision in congenital webbed penis.

Purpose: Hydrofluoric acid(HF) is one of the most dangerous mineral acids with dissociated fluoride ions. As hydrofluoric acid is present in various household products(such as rust removers), a large population of industrials is at the risk of HF exposure. It is a very strong organic acid, used widely in glass etching, metal washing, and in the semiconductor industry. Even when using adequate safety measures, lack of care on the user's part results in chemical burn by HF. Symptoms caused by HF-induced chemical burns shows delayed manifestations resulting in a loss of proper treatment opportunities. We therefore reviewed 20 cases of HF- induced chemical burns and treatment principle.Methods: The objects of this study were 19 male patients and 1 female treated from March 2004 to March 2006. There were 19 cases of injury on digits and 1 on the wrist area. There were 15 cases of immediate treatment after sustaining HF-induced burns, and 5 cases of delayed treatment. As a principle, in the emergency treatment, partial or complete removal of the nail along with copious washing with normal saline was done, depending on the degree of HF invasion of the distal digital extremities.Results: The 15 cases who came to the hospital immediately after the injury were healed completely without sequelae, and those who delayed their treatment needed secondary surgical measures, due to the severity of inflammation and necrosis of the digital tissues.Conclusion: As the industrial sector develops, the use of HF is increasing more and more, leading to increase in incidences of HF-induced chemical burns. When treating chemical burns caused by HF, washing by copious amounts of normal saline, along with early removal of the nails, rather than calcium gluconate, seems to be a available method for preserving the shape and function of the digits and the nail. The education of patients regarding this subject should be empathized accordingly.

Purpose: The goal of palatoplasty is focused on two points. One is to close the palatal defect completely, and the other to create a velopharyngeal system for normal speech. While established methods such as pushback palatoplasty or double opposing Z palatoplasty are used in wide cleft palate repair, sequelae such as maxillary hypoplasia or oronasal fistula may result. Therefore, when palatoplasty with buccinator myomucosal flap is used in the case of wide cleft palates, maxillary hypoplasia and oronasal fistula is reduced and optimal results are obtained. Methods: From October 2005 to December 2006, four children with wide complete cleft palate underwent unilateral buccinator myomucosal flap and intravelar veloplaty. Mean age at cleft repair was 15 months, and mean cleft size was 2.15cm. The patients underwent intravelar veloplasty and palatoplasty was done using unilateral buccinator myomucosal flap.Results: The patients, after mean 10 months of follow- up observation, showed no signs of oronasal fistula resulting from flap tension. The shape and color similar to normal oral mucosa was obtained, and velopharyngeal function was acquired.Conclusion: When intravelar veloplasty and palatoplasty with unilateral buccinator myomucosal flap is done on wide cleft palates, postoperative speech function is optimal, velopharyngeal incompetence is effectively corrected, and sequelae resulting from pushback palatoplasty and double opposing Z-plasty, such as maxillary hypoplasia and oronasal fistula, is reduced.

남승민,유상호,김정아,어은경,박소연,김장한 한국의료윤리학회 2020 한국의료윤리학회지 Vol.23 No.2

Purpose: To identify the core competencies of medical ethics for the Korean Medical Licensing Examination (KMLE). Methods: A literature review was conducted to determine the domains and details of the core competencies of medical ethics. A Delphi survey was then used to confirm these core competencies. The survey was conducted twice, using online Google Forms sent to selected medical ethics experts. The indices of core competencies were grouped into three categories: patient-doctor relationship, relationship between the healthcare sector and society, and individual field of expertise. Each category was further divided into three levels: sub-category, component, and definition of index. The questionnaire included the importance of the individual index as a core competency of medical ethics for the KMLE. The results were evaluated on a 4-point Likert scale. Results: The first Delphi questionnaire was sent to 36 willing participants, of whom 23 responded (response rate: 64%). The second Delphi survey was conducted with 23 respondents from the first survey, of whom 16 responded (response rate: 70%). To verify the importance and validity of the definition of index as a core competency of medical ethics, the medians and content validity ratios (CVR) were calculated and used to identify the core competencies of medical ethics for KMLE. Conclusion: Based on the above results, 3 categories, 17 sub-categories, 30 components, and 62 index definitions were identified as required core competencies of medical ethics for KMLE.

남승민,김성길 대한물리치료학회 2021 대한물리치료학회지 Vol.33 No.3

Purpose: Dementia is a disease in which cognitive function declines, leading to deterioration of body functions and activities of daily living. The purpose of this study is to explore the effects of dual-task training, including cognitive tasks, on cognitive and body function and β-amyloid levels in Alzheimer’s dementia patients. Methods: 34 inpatients diagnosed with Alzheimer’s dementia at a nursing hospital located in South Korea. The patients were randomly divided into a dual-task group (n=16) and a single-task group (n=18). Each group was trained for 30 minutes three times a week for eight weeks. The MMSE-K was used to measure the patients’ cognitive function. To assess the patients’ static balance ability, their LOS was measured using BioRescue. while dynamic balance was measured using the BBS. The 10MWT were conducted to evaluate the patients’ walking ability. Blood analysis was performed to measure levels of β-amyloid. Results: Both groups exhibited statistically significant improvements in gait function after the training (p<0.05). The dual-task group exhibited statistically significant differences in cognitive function, static and dynamic balance function, and β-amyloid levels after training (p<0.05). A significant difference was observed between the two groups (p<0.05). Conclusion: Dual-task training were found to be effective in improving cognitive and bodily functioning and reducing β-amyloid levels in Alzheimer’s dementia patients. Thus, this may be suggested as an effective exercise method for the treatment and early prevention of Alzheimer’s dementia.

남승민,김지호,이현정,송오영,Nam, Seung-Min,Kim, Ji-Ho,Lee, Hyun-Jeong,Song, Oh-Young 한국정보처리학회 2009 정보처리학회논문지 C : 정보통신,정보보안 Vol.16 No.1

최근 디지털 정보통신 기술의 발전으로 네트워크 기술 및 성능의 적용 범위가 모든 분야로 확대됨에 따라 모든 정보단말, 가전기기, 사물 등이 하나의 네트워크로 연결되는 차세대 통신환경으로 진화되고 있다. 이러한 차세대 통신 환경에서의 핵심기술인 IMS(IP Multimedia Subsystem) 기반 네트워크에서 원활한 통합서비스(convergence service)의 제공을 위해서는 사용하던 정보단말이 바뀌거나 네트워크가 변화하더라도 이용 받던 서비스들을 그대로 제공 받을 수 있는 끊김없는(seamless) 서비스가 가능하여야 한다. 본 논문은 IMS Enabler를 통한 통합서비스 제공환경에서 사용자의 네트워크 환경의 변화나 정보단말의 변화에도 끊김없는 서비스를 제공하기 위한 세션제어기법과 그 구조를 제안하고 그에 따른 서비스 세션 제어 프로토콜(Service Session Control Protocol : SSCP)을 제시한다. Recently, the application of network technology extends to all areas because of development of digital information technology. Thus, networks are being evolved towards a next-generation communication environments where all information devices, home appliances, and object are connected and interoperated. In order to provide adequate convergence services in IMS-based networks that are the core technology of the next-generation communication environments, seamless service should be possible although the underlying network and the device in use may change in the networks. In this paper, we propose an efficient architecture, algorithm, and protocol of service session control for seamless service in such networks.
