Purpose: Traditional radical surgery for vulvar cancer produces severe skin and soft tissue defects in the vulvar and vaginal area. Vulvoperineal V-Y advancement fasciocutaneous flaps have limitations in advancement and tension at the wound margin and vaginal orifice area, causing wound disruption or vaginal wall exposure. Therefore, we designed the "Butterfly flap" using a vulvoperineal V-Y advancement fasciocutaneous flap and an inguinal rotational skin flap for 3-dimensional reconstruction of vagina and vulvar area. Methods: A 27 year-old female was diagnosed with vulvar intraepithelial neoplasia. Radical vulvectomy and full-thickness-skin-graft was performed. We designed a vulvoperineal V-Y advancement fasciocutaneous flap as the greater wing and inguinal rotational skin as the lesser wing. After flap elevation, the inguinal flap was rotated $180^{\circ}$ to reconstruct the labia major and vaginal orifice. The perineum was reconstructed using V-Y advancement flaps. Results: The flap survived completely, without any complications. After 6 months, the patient was able to perform normal sexual activities and after 18 months, the patient was able to give birth to normal child by caesarean section. Conclusion: The traditional vulvoperineal V-Y advancement fasciocutaneous flap is thin, reliable, easily elevated and matches local skin quality. However, the vaginal wall becomes exposed due to limited advancement and tension of the flap. The "Butterfly flap" using a vulvoperineal V-Y advancement fasciocutaneous flap and an inguinal rotational skin flap is useful for the release of vaginal orifice contracture, reconstruction of the labia major, and 3-dimensional reconstruction of vagina and vulvar area.

목적 : 간절제술 후에는 간의 합성능력이 저하되고, 복수나 부종이 발생하게 된다. 본 연구에서는 이러한 상황에서 영양상태를 평가할 수 있는 적절한 지표를 검증하고자 하였다. 대상 및 방법 : 간세포암을 진단받고, 간절제술을 시행받은 65명의 환자를 대상으로 후향적으로 의무 기록을 분석하였다. 간절제 전 및 간절제 후 7일째 체중과 신체 체질량 지수, 혈액검사를 통해 영양 평가 지표를 측정하였다. 결과 : 65명의 환자중 남자는 52명, 여자는 13명으로 남녀 비는 4:1이었으며, 평균 연령은 56.2세였다. 수술 전 신체 체질량 지수는 저체중인 18.5 kg/m2 미만이 2명 (3.1%), 18.5-23kg/m2의 정상 범위가 22명(33.8%), 23-27.5 kg/m2의 과체중 상태가 19명(29.2%), 그리고 신체 체질량 지수 27.5 kg/m2 이상의 비만 상태가 22명(33.8%)였다. 수술 전 후의 영양 평가 항목의 변화를 살펴보면, 수술 후 림프구 수, 총 단백질량, 알부민, 혈액 요소 질소(BUN), 콜레스테롤, 프리알부민 수치가 유의하게 감소하였으며, 반면에 백혈구 세포수(5642±1831 vs. 7149±3069)와 CRP(2.98±4.78 vs. 25.69±22.23)는 눈에 띄게 증가하는 소견을 보였다(p=0.00, p=0.00). 수술 전과 후의 신체 체질량 지수와 체중은 통계학적으로 의미있는 변화는 보이지 않았다(p=1.91, p=8.23). 결론 : 간절제술 시행 후 영양 상태를 정확하게 평가하기 위해서, 염증 반응과 외부의 개입에 의한 영향 등을 고려하여, 쉽게 적용 할 수 있는 단일 영양 상태 평가 지표로는 프리알부민이 가장 적합할 것으로 사료된다. After hepatic resection, a synthetic liver function is often deteriorated, and ascites have been occasionally developed. Because of these limitations, this study is designed to validate the optimal nutritional index. We retrospectively reviewed medical records of sixty-five patients who underwent hepatectomy for hepatocellular carcinoma. Body weight, Body Mass Index (BMI) and laboratory parameters were compared at preoperative day and postoperative day 7. Patients consist of fifty-two males and thirteen females and average age is 56.2±9.9 years old. Forty-four patients had resected more than three segments, and twelve had resected 2 segments and nine had resected only one segment or received a wedge resection. According to preoperative BMI, there were two underweight (BMI < 18.5), twenty-two normal, nineteen overweight, and twenty-two obese (BMI>=27.5). After the surgery, lymphocyte count, total protein, albumin, BUN, Cholesterol, Prealbumin statistically significantly increased (p=0.00 & p=0.00). However, BMI and change in Body weight do not show statistically significant data (p=1.91, p=8.23). The degree of inflammation may have a significant influence in nutrition evaluation scale. Therefore, a new method of nutritional evaluation that can adjust degree of inflammation is needed to accurately evaluate the nutrition scale after hepatectomy.

N/A Objectives: Paraoxonase is a high-density-lipoprotein-associated enzyme capable of hydrolysing lipid peroxides. Thus it might protect lipoproteins from oxidation. It has two isoforms, which arise from a glutamine (A isoform) to arginine (B isoform) interchange at position 192. More recently, Ruiz et al. investigated the relationship between the paraoxonase genetic polymorphism and coronary heart disease in a case-control study of NIDDM in France. We investigated the correlation between the polymorphism of paraoxonase gene and cardiovascular disease in Korean diabetic patients. Methods: Of 106 patients with NIDDM, 50 had confirmed cardiovascular disease (coronary heart disease or ischemic stroke). The other 56 patients had no history of such disease and ECG abnormality. An additional control group of non-diabetic, healthy subjects (N=55) was selected. The polymorphism of paraoxonase gene was assessed by VCB-RFLP in their blood leukocytes DNA. Results: The healthy control revealed paraoxonase genotype frequencies of 18.1% AA, 36.4% AB and 45.5% BB. The NIDDM group revealed paraoxonase genotype frequencies of 11.3% AA, 39.6% AB, 49.1% BB. The genotype frequencies did not differ between healthy control with diabetic group. The genotype frequencies did not differ between diabetic group with coronary heart disease and diabetic control group(AA; 8.4% vs 12.5%, AR; 45.8% vs 37.5%, BB; 45.8% vs 50.0%). There was also no difference in genotype frequencies between diabetic group with ischemic stroke and diabetic control (AA; 11.5% vs 12.5%, AB; 38.5% vs 37.5%, BB; 50.0% vs 50.0%). In multiple logistic regression analysis with other risk factors, hypertension emerged as the most related factors for cardiovascular disease, but paraoxonase genotype was not associated with the presence of cardiovascular disease. Conclusion: In Korean diabetic patients, the polymorphism of paraoxonase gene might not be associated with the presence of coronary heart disease or ischemic stroke.

Marketing activities play an important role in determining sales performances for B2B companies; however, prior research implies that the effect of marketing activities in the industrial market cannot be inferred from findings in the consumer market due to their differences such as types of customers or products. We further note that B2C companies (i.e. B2B client companies) serve individual consumers, and thus, B2B sales performance can be better understood as consumer market contexts are also taken into account. In this research, we study B2B marketing activities and B2C market contexts, and their effects on B2B sales performance. To this end, we focus on three factors : sales calls conducted by B2B companies, and market commercialization and social interactions in regions where B2C companies operate. Our empirical analyses provide the following results. First, B2B sales performance improves in proportion to sales calls. When sales calls serve as the means to provide product information, they help client companies understand product benefits and make purchases accordingly. Second, B2B sales performance increases as B2C markets become more commercialized, but the effect of sales calls on B2B sales declines. Commercialized markets are more attractive to individual consumers and thus, lead to greater sales in the consumer market. However, the role of sales calls as information sources weakens as B2C companies share product information themselves and develop expertise in commercialized markets. Finally, B2B sales are greater in urban markets compared to suburbs. However, the effect of sales calls on B2B sales increases in suburban markets compared to the urban counterpart. Cohesive social interactions in suburbs hinder information diffusion among B2C companies, which in turn strengthens the role of sales calls as information sources. We theoretically contribute to the B2B marketing literature and managerially suggest strategies to improve B2B sales performance.
