Ja Woong Goo,Ye Jin Jung,Jae Hong Kim,Sung Yul Lee,Sung Ku Ahn 대한피부과학회 2010 Annals of Dermatology Vol.22 No.1

Superficial acral fibromyxoma (SAFM) is a rare myxoid tumor that was first described in 2001. The presence of a very slow growing solitary tender mass in the subungual area is the typical clinical feature at presentation. Histopathologically, SAFM is composed of stellate cells in a myxocollagenous matrix with a poorly circumscribed margin. This tumor is thought to be benign, but its natural course is not fully understood. We describe a 15-year-old patient with recurrent SAFM and discuss the proper treatment and follow up.

Background: To meet the need for a subspecialized skin type system, the Baumann skin type (BST) system was proposed. Objective: To evaluate the distribution of BST types and influencing factors among Korean women. Methods: BST questionnaires were administered to 1,000 Korean women. The possible responses were as follows: oily (O) or dry (D), sensitive (S) or resistant (R), pigmented (P) or non-pigmented (N), and wrinkled (W) or tight (T). The correlations of the BST with the subjects` age, location, ultraviolet (UV) ray exposure, drinking and smoking habits, and blood type were assessed. Results: The OSNT, DSNT, DRNT, and OSNW skin types were the most common skin types (55.3%). The O, S, P, and W types accounted for 46.6%, 68.8%, 23.2%, and 31.9%, respectively. The proportion of the O and S type was the highest in Gyeongsangbuk-do (55.0%) and Seoul (77.2%). The proportion of the P and W type was the highest in Gyeongsangbuk-do (33.0%) and Chungcheong-do (39.0%). The O type decreased in the higher age group, whereas the P and W type showed a reversed tendency. In smokers, the proportion of W type was significantly higher than in the non-smokers (66.3% vs. 24.1%, p<0.05). Conclusion: The 4 most common BST types were OSNT, DSNT, DRNT, and OSNW. In the comparison across the 4 BST parameters according to the age, region, smoking and drinking habits, occupation, blood type, and UV exposure, significant differences were observed. Individualized and customized skin care is required according to the personal skin type. (Ann Dermatol 29(5) 586∼596, 2017)

Acupuncture Meridian and Intravascular Bonghan Duct

Baik, Ku Youn,Lee, Ja Woong,Lee, Byung Cheon,Johng, Hyeon Min,Nam, Tae Jeong,Sung, Baeckkyoung,Cho, Sung Il,Soh, Kwang Sup Trans Tech Publications, Ltd. 2005 Key Engineering Materials Vol.277 No.-

<P>Current anatomical theory does not recognize the existence of an extended floating threadlike structure inside the blood vessels. Nonetheless, this study developed a new method for observing such an intravascular threadlike structure. The key technique involves injecting acridineorange into the femoral vein to circulate along the blood vessels and stain the nuclei of the intravascular threads inside the blood vessels. In-situ observations were then made under a fluorescence stereomicroscope after saline-perfusion. Confocal microscope images revealed a distinctive characteristic pattern of nucleus distribution that was clearly distinguishable from fibrin, capillaries, small venules, arterioles, or lymph vessels. Accordingly, it is suggested that the identified intravascular threads are part of the Bonghan's circulatory network that is distributed throughout the body, including inside the blood vessels.</P>

Hemophagocytic syndrome is a rare complication of a systemic infection that can have a fatal outcome. The skin manifestations can present as erythematous patches or nodules, purpura, ulcers, or edema. But the histopathologic features solely consist of infiltration of benign histiocytes and hemophagocytosis. We report a case of a 67 year-old male patient diagnosed with hemophagocytic syndrome caused by Pseudomonas aeruginosa infection. (Korean J Dermatol 2006;44(12):1430~1433)

운동화, 하이힐, 그리고 킬힐에 따른 족압과 주관적 불편도 평가

Ten young females were participated in this study to investigate the effects of types of shoes (sneakers, high heels, kill heels), types of tasks (standing, walking floor, step up and down), and areas of foot (fore foot, middle foot, rear foot) on foot pressures as well as subjective discomfort ratings. Results showed that kill heels had the most discomfort shoes, followed by high heels and sneakers. Generally, as the heel was higher, the discomfort of foot increased. For the analyses of task types, generally discomfort ratings were highest for the step down and up, followed by walking floor and standing. Especially discomfort ratings of high heels and kill heels were more evident in case of step up and step down than standing and walking floor. Standing task was rated as the lowest levels of discomfort on users' foot. Peak and mean foot pressures were also evaluated in this study. The findings represented that there was no significant differences between types of shoes in both peak and mean foot pressures. The peak pressure (82.14㎪) and mean pressure (40.32㎪) for standing task were significantly lower than those of other tasks [walking floor (190.55kPa, 55.46㎪), step up (191.43kPa, 53.80kPa), and step down (200.66㎪, 52.62㎪)]. Generally discomfort ratings and peak/mean pressures associated with foot showed that fore foot had higher discomfort ratings as well as peak and mean pressures than middle and rear foots. In particularly, this trend was more obvious in case of high heels and kill heels. For the high heels and kill heels, the peak pressures of fore foot were 4.5~4.8 times and 2.3~2.5 times greater than that of middle foot and rear foot, respectively, whereas the peak pressures of fore foot were 2.9 times and 1.7 times greater than that of middle and rear foots, respectively, in case of sneakers.

Purpose: Neoadjuvant chemotherapy is the standard treatment for patients with locally advanced breast cancer and is increasingly considered for patients with operable disease. Recently, as many clinical trials have demonstrated favorable outcomes of anthracycline-taxane based regimen, this approach has been widely used in the neoadjuvant setting. Methods: We compared women who received adriamycine and docetaxel (AD) with adriamycin, cyclophosphamide followed by paclitaxel (AC-T) as neoadjuvant chemotherapy. The AD group was scheduled for six cycles of AD (50 mg/m<SUP>2</SUP> and 75 mg/m<SUP>2</SUP>, respectively) at a 3-week interval. The AC-T group was scheduled for four cycles of adriamycin and cyclophosphamide (50 mg/m<SUP>2</SUP> and 500 mg/m<SUP>2</SUP>, respectively) followed by four cycles of paclitaxel (175 mg/m<SUP>2</SUP>) at a 3-week interval. Results: The responses of chemotherapy were equivalent (overall response rate [AD, 75.7% vs. AC-T, 80.9%; P = 0.566], pathologic complete response [pCR] rate [breast and axilla: AD, 10.8% vs. AC-T, 12.8%; P = 1.000; breast only: AD, 18.9% vs. AC-T, 14.9%, P = 0.623], breast conserving surgery rate [P = 0.487], and breast conserving surgery conversion rate [P = 0.562]). The pCR rate in the breast was higher in the human epidermal growth factor receptor 2 (HER2) positive cases (HER2 positive 33.3% vs. negative 10%, P = 0.002). Although nonhematologic toxicities were comparable, hematologic toxicities were more severe in the AD group. Most women in the AD group suffered from grade 3/4 neutropenia (P < 0.001) and neutropenic fever (P < 0.001). Conclusion: Tumor responses were not different in various variables between the two groups. However, AC-T was a more tolerable regimen than AD in patients with breast cancer receiving neoadjuvant chemotherapy.

In-Situ Observation of New Extra-Vascular Threadlike Structure of Mouse Using a Fluorescence Stereoscopic Microscope

Sung, Baeck-Kyoung,Lee, Ja-Woong,Lee, Byung-Cheon,Johng, Hyun-Min,Baik, Ku-Youn,Nam, Tae-Jeong,Park, Dae-Hun,Soh, Kyeong-Sun,Soh, Kwang-Sup KOREAN PHARMACOPUNCTURE INSTITUTE 2004 Journal of pharmacopuncture Vol.7 No.3

We report the new threadlike structures outside the blood vessels of mice. For this, we developed an in-situ searching method of the structure by vital staining with the dye of acridine orange and using a fluorescent stereomicroscope designed specifically for this purpose. We consider that the newly found threadlike structure might be rediscovery of the extra-vascular Bonghan duct which was reported in 1963 by Bonghan Kim.
