A hospital is the most important infra-facility of the places which take care of people's body in social environment. There exist several environmental factors in the ways to heal the human body in hospital ward, but this study tried to look into the improvable pleasant sickroom environment with focus on light environment among the factors. In other words, this study aims at the research on proper daylight inflow into sickroom space as basic data for understanding the link between healing environment and natural lighting. In the simulation analysis through this research, this study completed the initial simulation using Autodesk Revit 2011 with focus on two types of individual multi-bed room units of the two general hospitals located in Gwangju City. This study made a simulation analysis of The two multi-bed rooms looking to the west using the weather data on Gwangju district, which is the strong point of ECOTECT2011. Conclusively, looking into the analysis of the simulation model in time of attaching the length of in & outside light shelf, the angle controlling of light shelf, the daylight factor and DA were found to show the tendency to decrease in the numerical value due to the decrease in sunlight inflow as the simulation model moved more toward the room from the window in comparison with the existing analysis of multi-bed rooms. Particularly, this study was able to read that the daylight factor and DA were more decreasing to improve at the light shelf than the existing bedrooms; conclusively, this study judges that the natural lighting simulation analysis could be helpful in improving the healing environment as basic data.

Primary liposarcoma of the mediastinum is a very rare and relatively slow growing tumor. Since the original description by Pallase and Roubier in 1916, there have been about 55 reported cases in world literature until 1985. Recently, we experienced one case of a primary mediastinal liposarcoma with malignant effusion. A 51-year-old man complained of dyspnea and chest discomfort. The chest plain films and computerized tomogram showed a huge mass of the posterior mediastinal space. The needle aspiration biopsy was done in the huge mass and the histologic examination revealed mediastinal round-cell type liposarcoma. Patient refused surgery or chemotherapy after establishing the diagnosis. About 6 months later, the metastatic pleural effusion was noted. After discharge, he was lost to follow up since then. The clinical and therapeutic features of the previously reported cases of primary liposarcoma arising in the mediastinum have been reviewed. Surgery may served to establish a tissue diagnosis, to relieved the patient's symptoms and result occasionally in a cure but radiotherapy or chemotherapy is ineffctive.

Background: Selective transforaminal epidural block (STEB) has showen effectiveness as a diagnostic and therapeutic option for the management of patients with low back pain or sciatica. This study was carried out in order to determine the short-term effects and prognostic factors associated with STEB in patients with low back pain or sciatica. Methods: Ninety-seven patients were selectedfor participation in this study. Their diagnosis were based werewason the clinical symptoms and MRI findings. We performed STEB under fluoroscopic guidance and injected 3 ml of radio opaque dye in order to confirm the technical success of the procedure. We then injected 20 mg of triamcinolone mixed into 3 ml of 0.5% mepivacaine. One month later, we classified the patient outcomes as excellent, good, moderate or poor, according to the degree of reduction in VAS score from baseline. The independent variables assessed included symptom duration, block level, number of blocks, primary diagnosis, prior caudal block, anterior epidural space filling of dye, medication history, demographic data, radiating pain, back surgery and spondylolisthesis. Results: At a mean follow-up period of 1 month after STEB, excellent results were noted in the patients diagnosed with herniated lumbar disc (70%), non-specific spondylosis (54%), spinal stenosis (44%), and failed back syndrome (28%). The patients with epidural adhesion and combined spondylolisthesis were associated with poorer outcomes. Combined caudal block, symptom duration and the extent of epidural spread of the drug were not related to the effectiveness of the treatment. Conclusions: Selective transforaminal epidural block is effective in treating patients with radiculopathy, such as herniated lumbar disc, but it isrelatively ineffective in treating patients with structural deformities, such as failed back syndrome and spondylolisthesis.

Background: In patients with lumbar spinal stenosis (LSS), lumbar flexion exercise (LFE) is considered a standard therapeutic exercise that widens the space between the spinal canal and intervertebral foramen. However, some researchers have reported that lumbar extension exercise (LEE) may improve lumbar pain and functional ability in patients with LSS. Although exercise intervention methods for patients with LSS have been widely applied in clinical settings, few studies have conducted comparative analysis of these exercise methods. Objects: This study aimed to compare the effects of LFE, LEE, and lumbar flexion combined with lumbar flexion-extension exercise (LFEE) on pain, range of motion (ROM), pelvic tilt angle, and functional gait ability in patients with LSS. Methods: A total of 30 patients with LSS, LFE (n1=10), LEE (n2=10), and LFEE (n3=10) were assigned to each of the three exercise groups. The numerical pain rating scale (NPRS), modified-modified schober test (MMST)-flexion, MMST-extension, pelvic tilt inclinometer, and 6-minute walking test (6MWT) were measured. Results: After the intervention, statistically significant differences were observed in the NPRS (p=.043), MMST-flexion (p<.001), MMST-extension (p<.001), and 6MWT (p=.005) between groups. According to the post hoc test, the NPRS was statistically significant difference between the LFEE and LEE groups (p=.034). The MMST-flexion was statistically significantly different between the LFE and LEE (p=.000), LFE and LFEE (p=.001), and LEE and LFEE (p=.001) groups. The MMST-extension was statistically significantly different between the LFE and LEE (p<.001), LFE and LFEE (p=.002), and LEE and LFEE (p=.008) groups. The 6MWT was statistically significantly different between the LFE and LFEE (p=.042) and the LEE and LFEE (p=.004) groups. Conclusion: This study suggested that LFEE was the most effective exercise for pain and functional gait ability in patients with LSS, LFE was the most effective exercise for lumbar flexion ROM, and LEE was the most effective exercise for lumbar extension ROM.

Endoscopic transthoracic sympathectomy (ETS) has recently become estabilished as a successful treatment for severe palmar and axillary hyperhidrosis. Descriptions have been published of neurolytic, operative and alternative endoscopic procedures involving thermocoagulation, laser coagulation, or or nonvideo-assisted ganglionectomy using equipment not widely available, with low morbidity and excellent results. All methods have advantage and disadvantages. A 19-year-old male who suffered from severe hyperhidrosis on face, palms and axillary areas, has been initially treated with stellate ganglion block in other pain clinic. He was transfered to our pain clinic for endoscopic thoracic sympathectomy. The patient was intubated left side 34 Fr. double lumen tube and positioned left semi-lateral position for right sympathectomy. Right side pneumothorax was created by clamping the ipsilateral side of the double lumen tube and aspiration of air. 11-mm trocar was introduced through incision at the third intercostal space in anterior axillary line, and then additional two 11-mm and 5-mm trocar was introduced through second and fifth intercostal space in mid axillary line. The lung was gently retracted and the parietal pleura over the heads of the appropriate ribs excised using 5-mm sharp insulated coagulating microprocesss. The T4, T3, and T2 ganglions, as well as accompanying rami communicantes, and other branchs arising from upper thoracic nerves to the brachial plexus and surrounding tissues were carefully dissected, coagulated. During sympathectomy, skin temperature of middle was continuously monitored. Elevation of palmar skin temperature intraoperatively indicated an adequate sympathectomy with a definite therapeutic effect. A No. 28 Fr. thoracotomy tube was introduced through a troca under video guidance, placed under water seal after the lung was reinflated. the controlateral side was performed same procedure. After bilateral sympathectomy, chest tubes were removed, and then, he was discharged 2 days after operation with great satisfaction. The ETS provides a well-tolerated, cost-effective alternative to thoracic sympathectomy for primary hyperhidrosis and sympathetic mediated neuropathic pain disorder. And T2 ganglion is considered the key ganglion for the treatment of primary hyperhidrosis. The low incidence of compensatory sweating may by explained by the limited extent of the sympathectomy.

배경: 복잡한 흉막강내 공간차지병소(complicated pleural space occupying lesions, SOL)의 치료는 그 병의 진행정도와 상태에 따라 흉막천자, 폐쇄식흉강삽관술, 섬유소용해제의 주입, 그리고 흉강경이나 개흉술을 이용한 수술적 치료 등이 선택될 수 있다. 특히 비디오 흉강경 수술이 발달함에 따라 개흉술의 단점을 극복하여 보다 적극적으로 비디오 흉강경을 이용한 수술(VATS)을 시행하여 좋은 결과를 보고하고 있다. 이에 저자들은 비디오 흉강경을 이용한 흉막 유착박리술과 박피술의 유용성과 조기수술의 효과에 대해 알아보고자 의무기록과 방사선 기록을 후향적으로 조사, 분석하였다. 대상 및 방법: 1996년 5월부터 2006년 4월까지 complicated plerual SOL 환자 64명(평균연령 $41.8{\pm}19.8$세)에서 시행한 65예의 VATS 흉막 박피술과 흉막 유착박리 술을 분석하였다. 결과 분석을 위해 수술후 단순흉부방사선 소견을 임의로 4군(Class)으로 나누었다. Class I: no or minimal pleural lesion, class II: blunting of costophrenic angle and mild pleural thickening, class III: elevated diaphgram or persistent lung collapse, class IV complicated or recurrent effusion. 결과: 수술전 환자들은 진단적, 치료적 시술로 41예에서 흉막천자술, 10예에서 pigtail catheter 삽입술, 11예에서 폐쇄식흉강삽관술, 그리고 10예에서 섬유소용해제 주입을 받았다. 증상발현 후부터 수술까지의 기간이(증상발현기간)평균 18.4일이었고, 심각한 합병증이나 사망예는 없었다. 수술결과 Class I 28예, II 13예, III 19예, IV 5예였으며, 증상발현기간과 수술시간과의 관계에서 통계적으로 유의한 차이를 보였다. 또한 증상발현기간 18일을 기준으로 조기수술군과 지연수술군으로 나누어 비교하면 단순흉부방사선 소견 class별로 빈도수에서 두군간에 유의한 차이를 보였다. 결론: 비디오 흉강경을 이용한 흉막 유착제거 술과 박피술은 Complicated pleural SOL 치료를 위한 안전하고 효과적인 방법이고, 보다 좋은 결과를 위해서 조기에 적극적인 수술이 필요하다.

의료용 선형가속기에서 발생되는 고 에너지 광자선은 콜리메이터에 의하여 누출되며 치료두부(head), 콜리메이터, 환자를 포함한 치료실내의 모든 벽과 구성 물질들에 의하여 많은 산란선이 발생된다. 방사선치료는 종양에 따라서 최소한 40 Gy에서 80 Gy까지 조사되기 때문에 주위건강조직 특히 생식가능한 사람에 대한 생식선의 피폭선량을 평가하여야하며 종양치료에 영향을 주지 않은 범위에서 가능한 방법을 동원하여 피폭선량을 줄여야한다. 방사선 안전관리등의 기술기준에 관한 규칙(과학기술부령 제17호) 제3절 의료분야의 특별기준, 제44조(진료환자의 방사선 피폭)에 의하면 진료를 위한 환자 피폭선량을 합리적으로 달성 가능한 최소의 수준으로 유지하기 위한 절차를 구비하여야 하며 과학기술부 장관은 이에 준하는 의료시설 및 장비취급의 기술기준을 정하고 고시하여야한다고 명시 되어있다. 고 에너지방사선은 악성종양환자들의 치료성과를 향상시키는 동시에 치료후 방사선에 의한 만성효과가 발생 될 수 있기 때문에 주선속의 다양한 산란선과 누출선의 선질변화와 선량을 측정하고 생식선과 같은 주요장기를 산란선으로부터 차폐할 수 있는 기구를 제작 사용함으로서 방사선 피폭선량을 최대한으로 감소시킬 수 있었다. 고 에너지 방사선은 의료용 선형가속기(CLINAC 2100C/D. 2100C. 600C)에서 발생시킨 4, 6, 10 MV x-ray와 코발트원격치료장치(ALCYON II)의 코발트선원에서 방출되는 1.25 MV의 감마선을 이용하였다. 선량측정은 폴리스틸렌과 인체팬텀(Rando)사용하였으며 측정기는 이온함, TLD 및 필름을 사용하였다. 고 에너지 방사선에 의한 산란선은 장치의 콜리메이터 뿐만 아니라 치료실 벽 인체내부등 모든 방향에서 방사됨으로 납 벽돌에 의한 차폐율측정은 많은 변수를 가졌으며 고환인 경우에는 3면이 모두 차폐되도록 항아리모양으로 제작하였다. 태아인 경우 태아가 위치하고 있는 골반위에 육교모양의 선반을 만들고 그 위에 납 벽돌을 장치하도록 고안하였다. Co-60 감마선, 4 MV x-선, 10 MV x-선에서 발생되는 누출선량과 산란선량에 의한 평균 피폭선량은 조사면 중심으로부터 10, 30, 60cm 거리에서 조사면내 최대선량에 대하여 각각 $10^{-2},\;10^{-3},\;10^{-4}$의 비율로 측정되었으며 거리에 따라 지수함수로 줄어들었다. 흉부에 국한된 종양을 10 MV x-ray, $12{\times}12 cm^2$ 조사면으로 치료하였을 때 자궁에 받는 피폭선량은 0.9 mGy/Gy이며 고환이 받는 피폭선량은 0.6 mGy/Gy 이었으며 체장과 신장은 각각 4.8 mGy/Gy 와 2.5 mGy/Gy이다 10 MV x-선, $14{\times}14cm^2$ 조사면 경계로부터 10 cm 밖에서 납벽돌의 반가층 두께는 약 9.0 mm 이였고 20cm 밖에서는 반가층 두께가 약 6.5 mm로 측정되었다. 복부에 위치한 악성종양을 60 Gy 조사하였을 경우 태아가 위치하고 있는 자궁의 피폭선량은 약 370 mGy이고 이곳을 10 mGy이하가 되도록 차폐하려면 약 6.2 cm두께의 납 벽돌을 자궁위에 장착하여야 하며 골반치료시 고환에 10 mGy이하가 되도록 차폐하려면 약 5 cm 두께의 납 항아리가 요구된다. 고 에너지 고 준위 방사선치료시 고환은 3면을 항아리모양으로 차폐할 수 있어 피폭선량을 상당히 줄일 수 있으며 자궁인 경우 체내에서 산란된 선량의 차폐는 불가능하였다.

Objective: To study the relationship between clinical pathologic characteristics, treatment modalities and prognostic factors in HER-2 (Human Epidermal growth factor Receptor-2) overexpressed breast carcinoma. Materials and Methods: Major clinico-pathological factors including therapeutic modalities and survival status of 371 breast cancer patients with HER2 over-expression, teated at Yantai Yuhuangding Hospital from March of 2002 to December of 2010 were retrospectively studied, with special attention focused on survival-related factors. Results: The median age of the total 371 patients in this study was 48 years at time of diagnosis, among which, the leading pathological type was infiltrating ductal carcinoma (92.5%); 62.8% presented with a primary tomor larger than 2 cm in diameter at diagnosis, 51.0% had axillary lymph node (ALN) metastases; ER (Estrogen receptor)/PR (Progesterone receptor) double negative occured in 52.8% of cases, and PCNA (proliferation cell nuclear antigen) (+++) was found in 55.1%. HER-2 overexpressed patients were usually in advanced stage when the diagnosis was made (72.8% at stages IIA~IIIC). The prognosis and survival were assessed in 259 patients with complete follow-up data. 5-year DFS (disease-free survival) and OS (overall survival) rate was 68.0% and 78.0% respectively. Univariate analysis revealed that age, tumor size, ALN metastases, LVSI (lymph-vascular space involvement), PCNA status, hormonal therapy, chemotherapy cycles, and HER-2 overexpression, correlated closely with the prognosis. ALN metastases, LVSI, PCNA status and chemotherapy cycles were independent predictors of survival. Conclusions: HER-2 overexpressed breast cancer has special clinical and pathological characteristics, with advanced clinical stages and high rate of ER/PR double negative. Lymph node metastases, LVSI, PCNA and chemotherapy cycles are independent predictors of prognosis.
