  • With improving survival of children with complex congenital heart disease (CCHD), postoperative complications, like protein-losing enteropathy (PLE) are increasingly encountered. A 3-year-old girl with surgically corrected CCHD (ventricular inversion/L-transposition of the great arteries, ventricular septal defect, pulmonary atresia, postdouble switch procedure [Rastelli and Glenn]) developed chylothoraces. She was treated with pleurodesis, thoracic duct ligation and subsequently developed chylous ascites and PLE (serum albumin ${\leq}0.9g/dL$) and was malnourished, despite nutritional rehabilitation. Lymphangioscintigraphy/single-photon emission computed tomography showed lymphatic obstruction at the cisterna chyli level. A segmental chyle leak and chylous lymphangiectasia were confirmed by gastrointestinal endoscopy, magnetic resonance (MR) enterography, and MR lymphangiography. Selective glue embolization of leaking intestinal lymphatic trunks led to prompt reversal of PLE. Serum albumin level and weight gain markedly improved and have been maintained for over 3 years. Selective interventional embolization reversed this devastating lymphatic complication of surgically corrected CCHD.

  • 연구배경 : 폐암의 말기에 관찰되는 기도 폐쇄는 호흡곤란, 기침, 객혈 및 발열 등을 일으키고 반복적인 호흡기계 감염의 원인이 되기도 한다. 그러나 대부분의 경우 방사선 치료, 항암화학요법 또는 수술적 치료를 받았기 때문에 더 이상 치료를 할 수 없는 어려움이 있다. 따라서 기도 폐쇄를 호전시키기 위한 보조적인 방법으로 광역동 치료가 한 방법임이 알려져 있다. 방 법 : 기도 폐쇄가 관찰되는 폐암 환자에게 기관지 내시경 시행 48시간 전에 광감작물질인 porfimer sodium (Photofrin$^{(R)}$)을 kg당 2mg으로 정맥주사 후 일광화상 및 광과민반응을 방지하기 위해 직사광선을 차단시켰다. Light source는 diode laser를 이용하였고, light dose는 180-200 $joul/cm^2$, 방사하는 빛의 강도는 400 $mW/cm^2$ 으로 하였으며 interstitial irradiation 및 cylindrical diffuser 를 이용하여 630nm의 레이져를 조사하였다. 시행 48시간 후 기관지내시경을 시행하여 괴사된 조직을 제거하고 남아있는 종양 부위에 대해 재조사를 시행하였다. 결 과 : 폐암 수술 후 수술부위의 국소적인 재발을 보인 경우가 1예, 기도 폐쇄로 인한 호흡곤란을 호전시키기 위해 시행한 경우가 4예였다. 광역동 치료를 통해 종양조직의 선택적인 괴사를 관찰할 수 있었고 괴사조직을 제거한 후에는 기도 폐쇄가 4예에서 호전되었다. 광역동 치료 종결 후 호흡곤란 및 활동도가 호전된 경우가 3예에서 관찰되었고 폐쇄성 폐렴으로 인한 객담 및 발열의 소견 및 기관지암에 의한 객혈의 경우에도 광역동 치료 후 호전되었다. 결 론 : 기도 폐쇄가 관찰되는 폐암 환자에서 보존적인 치료 방법으로 기관지내시경을 이용한 광역동 치료는 호흡곤란, 반복적인 호흡기계 감염 및 객혈 등을 호전시키기 위한 효과적인 방법 중의 하나이다.

  • Supravalvular aortic stenosis may be defined as an obstructive congenital deformity of the ascending aorta which originates just distal to the level of the origin of the coronary arteries. It may occur in several different anatomical form. Three type have been described; the hourglass, the hypoplastic and the membranous type, each term identifying the gross characteristic of the lesion causing by the aortic obstruction. Non cardiovascular condition commonly associated with supravalvular aortic stenosis are mental retardation, facial anomalies, hypercalcemia, etc. The diagnosis can be established preoperatively by left heart catheterization and selective angiography. Recently, we experienced a case of multiple localized supravalvular aortic stenosis involving, just above the sinus Valsalva and just proximal of the innominate artery. The surgical correction which was performed by a vertical incision across the each narrowing of aorta with replacement of diamond shaped double velour Woven Dacron patch under the CPB. He was discharged without any event.

  • 서 론 : Phosphodiesterase (PDE) 억제제는 세포내 cAMP를 증가시키며, cAMP는 TGF-${\beta}1$에 의한 connective tissue growth factor (CTGF)의 발현을 억제하는 것으로 알러져 있다. 그러므로 저자들은 PDE 억제재가 TGF-${\beta}1$의 변화 없이 긴 섬유화를 억제할 수 있는지를 확인해 보고자 본 연구를 시행하였다. 방 법 : 백서에서 일측성 요관 결찰로 신 간질 섬유화를 유발하였다. 실험군에서는 PDE3 억제제인 cilostazol (1 g/L)이나 PDE5, PDE6, PDE8의 hybrid 억제제인 dipyridamole (750 mg/L)이 첨가된 음료수를 공급하였다. 일주일 후 신장을 적출하여 Masson-trichrome score를 평가하고, 신조직 조건배지에서 fibronectin과 TGF-${\beta}1$을 ELISA법으로 정량하였다. 결 과 : 대조군에 비해 cilostazol 군에서 Masson-trichrome score와 신조직 조건배지의 fibronectin 농도가 유의하게 낮았다(P<0.05). Dipyridamole군의 Masson-trichrome score와 조건배지의 fibronectin 농도도 대조군에 비해 낮아 보였으나 통계적 유의성을 보여주지 못했다. 신조직 조건배지의 TGF-${\beta}1$ 농도는 대조군, cilostazol군, dipyridamole군간에 차이가 없었다. 결 론 : 선택적 PDE3 억제제인 cilostazol은 TGF-${\beta}1$의 억제에 의존하지 않고 일측성 요로 폐쇄에 의한 신 섬유화를 억제하였다.

  • The role of adjuvant chemotherapy in patients with stage II colon cancer remains a controversial issue. Adjuvant chemotherapy aims to eliminate any micrometastatic disease that may have been missed, at the time of surgery. Although one prospective study showed a small but statistically significant benefit with respect to the overall survival for those who received adjuvant chemotherapy, multiple pooled data did not demonstrate any benefit of this therapy in patients with stage II colon cancer. Current national and international guidelines for the adjuvant treatment of stage II colon dose not advise routine implementation of adjuvant chemotherapy, but rather recommend selective use of this therapy for patients with high risk of recurrence. High risk features for recurrence include T4 disease, poorly differentiated histology, presence of lymphovascular invasion, presence of perineural invasion, inadequate retrieval of lymph nodes, bowel obstruction, localized perforation, or positive margins. More recently, prediction tools using gene expression cancer profiles are proposed to identify patients who are most likely to have recurrence and therefore may benefit from postoperative chemotherapy in stage II colon cancer. These novel methods together with conventional prognosticators, will allow us to implement more optimized personalizing adjuvant therapy in these patients.

  • The purpose of this study is to investigate adult learners' experience by studying Humanities & General Education and get to know types and characteristics by classifying their learning experiences. This study uses grounded theory method which is suitable to investigate subjective experiences. In this study, data is collected from 13 adult learners by using Focus Group Interview(FGI) who participate in learning experience of Humanities & General Education of D university in Busan region. The data is categorized by open coding, axial coding and selective coding based on data analysis method of grounded theory and analysis processes. This study provides several outcomes as follows: 113 concepts, 38 subcategories and 16 upper categories are derived through the process of abbreviation and categorization of learning experience of Humanities & General Education. In a process of learning experience, this study shows interrelationship in a frame of paradigm and derives results of a process of abbreviation and categorization casual condition, contextual condition, phenomenon and interaction(help/obstruction factor). Tree types of learning experiences and characteristics are drawn as follows: 1) "Self-realization" is the type who participate in Humanities & General Education with desire of learning and they want to find identity and plan detailed future. 2) "The pursuit of happiness" has less desire on learning than "self-realization" and they are types who participate in Humanities & General Education because of someone else's help and suggestion. 3) "Local community" is the type who participate in Humanities & General Education because they feel necessity of social role and they expect local development based on their interest in local community. Several conclusions and suggestions are provided for further studies.

  • Purpose: To evaluate the initial experience and outcome of photo-selective vaporization of the prostate (PVP) for benign prostatic hyperplasia (BPH) in Pakistan with the use of a 980 nm diode laser. Materials and Methods: A prospective study was performed from November 2016 to December 2017. A total of 100 patients diagnosed with bladder outlet obstruction secondary to BPH who planned for PVP were enrolled in the study. PVP was carried out with a diode laser at 980 nm (Biolitec Diode 180W laser) in a continuous wave with a 600 nm (twister) fiber. Baseline characteristics and perioperative data were compared. Postoperative outcomes were evaluated by International Prostate Symptom Score (IPSS), post void residual (PVR) and maximum urinary flow rate (Qmax) at 3 and 6 months after surgery. Results: The mean age was $65.82{\pm}10.42$, mean prostate size was $67.35{\pm}16.42$, operative time was $55.85{\pm}18.01$ and total energy was $198.68{\pm}49.12kJ$. At 3 months and 6 months, significant improvements were noted (p<0.001) in IPSS $7.04{\pm}1.69$ (-18.92), Qmax $19.22{\pm}4.75mL/s$ (+13.09) and and PVR $18.89{\pm}5.39mL$ (-112.80). Most frequent problems were burning micturition (35%) and terminal dysuria (29%). No significant difference in postoperative hemoglobin was seen in patients who were on anti-platelet drugs. Conclusions: PVP with a diode laser is a safe and effective procedure for the treatment of BPH and is also safe in patients who are on anti-platelet agents.

  • Objective : Although management of asthma has become increasingly effective, its cure remains elusive, necessitating a new modality to prevent or eliminate causes triggering clinical progress. Based in the clinical experiences, a novel decoration Cheongsangbiyeum (CSB), has been developed to treat asthma, which consists of Polyporus, Semen Myristicae, Pericarpium citri Reticulatae, Rhizoma Cimicifugae, Cortex Albizziae, Fructus Rubi, Rhizoma Zedoariae, and Rhizoma Rhei. In the current study, its anti-asthmatic efficacy was evaluated using a mouse model of asthma. Methods : Experimental allergic asthma was induced by repeated intraperitioneal sensitization and intranasal challenge of ovalbumin (OVA). Water extract of CSB (1 mg/mouse/day) was administrated orally whereas control mice on given with identical volume of phosphate-buffered saline (PBS) for 5 days during the course of antigen challenge. When airway hyperreactivity(AHR) measured by ${\bata}-methacoline-induced$ airflow obstruction was compared, AHR of CSB-treated mice was significantly lower than those of control mice, indicating that CM extract can attenuate an asthmatic symptom. Airway recruitment of leukocytes and eosinophils was also markedly reduced by CSB treatment suggesting that oral treatment of CSB can alleviate the airway inflammation. For a better understanding of possible mechanisms underlying anti-asthmatic effet of CSB, cytokine (IL-4, IL-5, IL-13 and $IFN{\gamma}$ levels in bronchoalveola lavage fluid (BALF) and lung tissues were determined. Results : The results showed that cytokine levels were significantly lowered by CSB treatment. Additionally, number of draining lymph node cells was significantly lower than those of control mice. These data indicate that CSB suppress in vivo allergen-specific response. However, notably, levels of type 2 cytokines such as IL-5 and IL-13 were more profoundly influenced. Moreover, in vitro OVA-specific proliferative response and type 2 cytokine (IL-4, IL-5 and IL-13) production lymph node cells was markedly decreased in CSB-treated mice, whereas their $IFN{\gamma}$ production was not significantly altered Thrse data clearly showed a preferential inhibition of type 2 T cell (Th2) response by CSB treatment. This finding was also supported by serum antibody data showing that levels of OVA-specific type 2 antibodies, IgE and IgG1, in CSB-treated mice were significantly lower than in control mice, while type 1 antibody, IgG2a level m rather higher than controls, although the difference was in significant. Conclusions : In conclusion, oral administration of CSB attenuates asthmatic manifestations including AHR ad airway recruitment of eosinophils in a mouse model which possibly results from selective inhibition of Th2 cell response to allergen. Our data suggest a potential clinical application of CSB for control of allergic asthma.

  • 좌우 경동맥을 결찰하여 혈뇌장벽에 변화를 일으킨 백토에서 뇌압하강제(mannitol, steroid) 및 뇌압하강 방법(과호흡)의 효과를 관찰하였다. Mannitol군에서는 steroid군, 과호흡군에 비해 뇌압감소가 통계적으로 유의하게 있었으며, 시간적으로 mannitol 투여 후 25~30분까지 뇌압이 45%까지 감소하여 지속되었다. Steroid군에서는 mannitol군보다는 뇌압 절대치의 감소폭은 적었지만, 과호흡군 보다 2배 이상의 뇌압감소가 있었고, mannitol군보다 더욱 오랫동안 뇌압감소의 효과가 지속되었다. 과호흡군에서는 mannitol군, steroid군에서보다는 뇌압감소 효과가 적었으나, 과호흡 시행 후 10분까지 13.5~16.7%의 뇌압감소가 있었고, 그 이후 시간 경과에 따른 더 이상의 뇌압감소 효과는 없었다. Mannitol, steroid, 과호흡군을 모두 시행한 복합치료군에서는 mannitol 및 steroid, 과호흡을 각각 시행한 군에서보다 뇌압 감소가 더욱 현저하게 이루어져 30분까지 48~52%의 뇌압감소가 있었다. 이상의 결과로 미루어보아 뇌허혈성 뇌졸중 환자에서 mannitol 및 steroid사용과 병행하여 과호흡을 실시함으로써 뇌압감소를 위한 적절한 치료의 지표가 될 것이라 판단다.
