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.

남승민,왕다희,최수석 한국고분자학회 2021 한국고분자학회 학술대회 연구논문 초록집 Vol.46 No.2

Chiral gels using a repeating helicoidal molecular rotation of optically anisotropic soft matter such as nematic liquid crystals and the reactive mesogenic elastomer self-organize a periodic dielectric tensor. The helical structure results in modulation of electromagnetic light propagation when the periodicity has matched the wavelength of the light and can allow further wavelength tunable properties against addressing various external stimuli including temperature, light, electric field, and mechanical deformation. Especially, mechanochromic response behaviors of chiral gels which are from elastomer are particularly interesting for photonics applications. In this study, we studied the simple and easy fabrication procedure of chiral gels with elastomers via two-stage Thiol-Michael addition reaction and their optical characteristics by mechanical deformation. Detailed optical behaviors of fabricated chiral gels will be discussed either with high optical quality and wide tunability.

남승민,최환준,김미선 대한성형외과학회 2007 Archives of Plastic Surgery Vol.34 No.4

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.

남승민,이도연 한국산학기술학회 2019 한국산학기술학회논문지 Vol.20 No.11

This study was undertaken to determine the correlation between β-amyloid, serum lipid levels, and cognitive function in the elderly with mild Alzheimer's dementia. The study was conducted in December 2018, enrolling 45 elderly people with mild Alzheimer's disease. Blood analysis measured the β-amyloid and serum lipid levels, and cognitive function was measured using MMSE-K. The correlation between β-amyloid, serum lipid levels and cognitive function was determined using Pearson's correlation analysis. A significantly negative correlation was observed between the β-amyloid level and cognitive function (p<0.05). Furthermore, serum lipid levels and cognitive function also revealed a significantly negative correlation between TC and LDL levels (p<0.05). These results indicate that increasing levels of β-amyloid, TC, and LDL augments a negative correlation that decreases the cognitive function, signifying that management of pathologic factors related to dementia is important for the prevention and improvement of cognitive function in dementia patients. 본 연구는 경증 알츠하이머 치매 노인의 베타 아밀로이드 및 혈중 지질 수준과 인지기능 간의 상관관계를 알아보고자 실시하였다. 연구의 대상자는 경증 알츠하이머 치매 노인 45명을 대상으로 실시하였다. 2018년 12월 베타 아밀로이드 및 혈중 지질 수준을 측정하기 위해 혈액 분석을 실시하였으며, 인지기능의 측정을 위해 MMSE-K 검사를 이용하여 측정하였다. 베타 아밀로이드 및 혈중 지질 수준과 인지기능 간의 상관관계를 알아보기 위해 Pearson’s correlation analysis를 사용하여 분석하였다. 연구 결과 베타 아밀로이드 수준과 인지기능 간의 상관관계에서는 -.604로 유의한 음의 상관관계를 보였으며(p<.05), 혈중 지질 수준과 인지기능 간의 상관관계에서는 TC(total cholesterol)와 LDL(low density lipoprotein) 수준에서 각각 -.601, -.403로 유의한 음의 상관관계를 보였다(p<.05). 이와 같은 결과는 베타 아밀로이드 및 TC, LDL 수준이 증가할수록 인지기능이 감소하는 음의 상관관계가 나타나는 것을 알 수 있었다. 이처럼 치매 환자의 예방 및 인지기능의 증진을 위해서 치매 관련 병리학적 인자의 관리가 중요하다고 사료된다.

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.

Purpose: This study aimed to assess the accuracy of ultrasound (US) diagnosis for retrojugular lymphadenopathy in patients who had undergone total thyroidectomy, due to thyroid malignancy. Materials and Methods: During a follow-up period after total thyroidectomy, due to known thyroid malignancy, 41 patients underwent US diagnosis and US-guided fine-needle aspiration for retrojugular lymphadenopathy. Each lymphadenopathy was prospectively classified by a single radiologist into 1 of 3 diagnostic categories: “benign”, “indeterminate for malignancy”, and “malignant”. Based on the cytohistopathology result, thyroglobulin tittering, and sonographic follow-up, the adequacy of US diagnosis for retrojugular lymphadenopathy was assessed. Results: Of the 41 retrojugular lymphadenopathies, malignant (n = 25) and benign (n = 16) lymphadenopathy were finally confirmed. Excluding 15 lymph nodes with indeterminate US diagnosis, the sensitivity, specificity, positive and negative predictive values, accuracy, and false positive and negative rates of US diagnosis were 100%, 66.7%, 95.8%, 100%, 96.2%, 0%, and 10%, respectively. There was no significant difference in the incidence of retrojugular lymphadenopathy, according to age, sex, and location (p > 0.05). Conclusion: In the patient with a history of total thyroidectomy, due to thyroid malignancy, US diagnosis for retrojugular lymphadenopathy showed a high accuracy. 목적: 갑상선암으로 갑상선전절제술을 받았던 환자에서 경정맥 뒤에 위치하는 림프절 병변에(후경정맥 림프절) 대한 초음파 진단의 정확성을 알아보고자 하였다. 대상과 방법: 갑상선암으로 갑상선전절제술을 받았던 환자의 추적 초음파 검사에서 갑상선암의 후경정맥 림프절 전이가 의심되었던 환자 중에서 41명이 초음파유도하 세침흡인세포검사를 받았다. 각각의 후경정맥 림프절들은 초음파 소견을 바탕으로 한 명의 영상의학과 의사에 의해 3개의 카테고리(양성, 불확실, 악성) 중 하나로 분류되었다. 세포조직병리결과, 흡인액의 갑상선글로불린(thyroglobulin) 수치 및 추적 초음파 소견을 바탕으로 최종 진단된 결과를 기준으로 초음파진단의 정확성을 조사하였다. 결과: 41개의 후경정맥 림프절 병변에 대하여, 25개의 후경정맥 림프절에서 갑상선암의 전이가 있었고 나머지 16개에서는 양성 림프절 병변임이 최종적으로 확인되었다. 초음파 진단 결과가 불확실했던 증례를 제외하였을 때(15예), 후경정맥 림프절 병변에 대한 초음파 진단의 민감도, 특이도, 양성예측도, 음성예측도, 정확성, 위양성률 및 위음성률은 각각 100%, 66.7%, 95.8%, 100%, 96.2%, 0% 및 10%였다. 나이, 성별, 림프절의 위치에 따른 후경정맥의 악성 위험도에 있어서는 통계학적 유의성이 없었다(p > 0.05). 결론: 갑상선암으로 갑상선전절제술을 받았던 환자에서 후경정맥 림프절 병변에 대한 초음파 진단은 높은 정확성을 보였다.
