Malignant pleural mesothelioma (MPM) is a rare tumor that is difficult to clearly distinguish from an adenocarcinoma but usually has a poor prognosis. Numerous cytotoxic agents have been used in the primary treatment of MPM with limited success. A complete response is unusual and a partial response occurs in less than one-third of patients. Recently, a phase III trial showed that a combination of pemetrexed with cisplatin resulted in a significantly higher response rate and median survival time than with cisplatin alone. We encountered a case of a dramatic tumor response to pemetrexed/cisplatin combination chemotherapy in patients with MPM, which was resistant to the 1st-line gemcitabine/cisplatin therapy. After six cycles of pemetrexed/cisplatin combination chemotherapy, the tumor volume had decreased dramatically with complete symptom relief. There was no chemotherapy-related toxicity or scheduled violation. The patient is under maintenance chemotherapy with the same regimen.

Background/Aims: The primary aims of this study were to evaluate the content quality of YouTube videos on exercises to help relieve constipation and to assess whether the video source, exercise types, and popularity affected their quality. Methods: Eight gastroenterologists independently evaluated the exercises presented in the constipation YouTube videos for seven items: image quality, usefulness in relieving constipation (quality 1), usefulness for general physical health (quality 2), difficulty in following, activity intensity, fun, and overall quality. Raters were asked open-ended questions to evaluate the strengths and weaknesses of the videos. Five-point ordinal scales were used to score each item aforementioned, with the exception of image quality and overall quality that used a six-point Likert scale. Results: The 20 videos had a mean length of 268 seconds and a mean viewership of 32,694. The most common video source was commercial (n=10), and the most common type of physical activity was yoga (n=11). The median values of image quality, quality 1, quality 2, difficulty in following, activity intensity, fun, and overall quality were 3, 2, 2, 2, 2, 2, and 2, respectively. Yoga videos had significantly higher median quality 1 values (3) compared with massage videos (2, adjusted p=0.006) and 'others' videos (2, adjusted p<0.001). A lack of medical evidence was the most common answer to open-ended questions about the weaknesses of each video. Conclusions: Overall, YouTube exercise videos presented a low-quality content. This study highlights the need for evidence-based comprehensive educational videos addressing exercises for treating constipation.

Purpose: To investigate the outcomes of patients with spinal metastases from hepatocellular carcinoma (HCC), who were treated by stereotactic body radiotherapy (SBRT). Materials and Methods: This retrospective study evaluated 23 patients who underwent SBRT from October 2008 to August 2012 for 36 spinal metastases from HCC. SBRT consisted of approximately 2 fractionation schedules, which were 18 to 40 Gy in 1 to 4 fractions for group A lesions (n = 15) and 50 Gy in 10 fractions for group B lesions (n = 21). Results: The median follow-up period was 7 months (range, 2 to 16 months). Seven patients developed grade 1 or 2 gastrointestinal toxicity, and one developed grade 2 leucopenia. Compression fractures occurred in association with 25% of the lesions, with a median time to fracture of 2 months. Pain relief occurred in 92.3% and 68.4% of group A and B lesions, respectively. Radiologic response (complete and partial response) occurred in 80.0% and 61.9% of group A and B lesions, respectively. The estimated 1-year spinal-tumor progression-free survival rate was 78.5%. The median overall survival period and 1-year overall survival rate were 9 months (range, 2 to 16 months) and 25.7%, respectively. Conclusion: SBRT for spinal metastases from HCC is well tolerated and effective at providing pain relief and radiologic response. Because compression fractures develop at a high rate following SBRT for spinal metastases from primary HCC, careful follow up of the patient is required.

Objective : The purpose of this study was to analyze the relationship between fracture pattern and the development of acute radiculopathy after osteoporotic lumbar compression fracture. Methods : This study included 59 patients who underwent bone cement augmentation for osteoporotic compression fracture below the L2 level, which can lead to radiculopathic radiating pain. The patients were divided into two groups according to the presence of radiculopathy (group A : back pain only; group B : back pain with newly developed radiating pain). We categorized compression fractures into three types by the position of the fracture line. The incidence of newly developed radiculopathy was examined retrospectively for each compression fracture type. Results : The overall incidence of newly developed leg pain (group B) was 25%, and the frequency increased with descending spinal levels (L2 : 0%, L3 : 22%, L4 : 43%, and L5 : 63%). The back pain-only group (group A) had mostly superior-type fractures. On the other hand, the back pain with radiculopathy group (group B) had mostly inferior-type fractures. Most patients in group B showed significant relief of leg pain as well as back pain after bone cement augmentation. Conclusion : The incidence of a newly developed, radiating pain after osteoporotic compression fractures increased gradually from the L3 to L5 levels. Most of these fractures were of the inferior type, and the bone cement augmentation procedures seemed to be sufficient for relief of both back and radiating pain.

Objectives : Primary dysmenorrhea is one of the most common female gynecological diseases. Acupuncture and moxibustion therapy have been used to treat dysmenorrhea in Korea. The aim of this review was to examine the effectiveness of acupuncture and moxibustion therapy for primary dysmenorrhea as described in studies in Korea. Methods : A total of 8 databases were searched, with the search concluding February 15, 2015. These were the Oriental Medicine Advanced Searching Integrated System, DBpia, Korean Studies Information Service System, National Digital Science Library, Korean Traditional Knowledge Portal, Research Information Sharing Service, and Pubmed. Randomized controlled Trails(RCTs) comparing acupuncture or moxibustion therapy with non acupoints stimulation or medication were selected. Data abstraction and assessment of methodology was conducted by authors and disagreements were resolved by discussion. Results : 7 trials were included in this review, with a total of 308 participants. 4 trials reported on acupuncture, 1 trial reported on acupress by magnet, 1 trial reported on pharmacopuncture, and the other trial reported on moxibustion. Quality of methodology was low. 2 trials showed that experimental therapy was effective for pain relief compared to the controlled group. However, 5 trials did not show a significant difference in pain relief. Conclusions : Acupuncture and moxibustion therapy may reduce period pain, however, it is needed for well designed RCTs in Korea.

To evaluate the safety of propane cylinder, the flame test was performed by the flame exposure scenario of propane cylinder. The cylinder which was exposed in a flame was rapidly occurred to increase the internal pressure by liquid expansion, if so it cause of physical explosion. Therefore, the cylinder which was applied with thermal pressure relief device sholud be not bursted and the propane should be discharged to outside safely. The flame average temperature that was around of cylinder is $600^{\circ}C$, and then it increased $700^{\circ}C$ by discharged propane. The result of flame test, the cylinder was deformed, but it was not bursted. The regulations of flame exposure test for propane cylinder were not restricted, this paper can be applied to restrict the flame test if the cylinder is possible to expose the flame. Also, the results is expected as reference for estimation of the pressure cylinder performance.

From January,1981 to December,1985,22 patients with locally unresectable carcinoma of the pancreas were treated in the Department of Therapeutic Radiology, Seoul National University Hospital. Radiation was given in two spl it courses; each consisting of 2000 cGy over two weeks sepatated by two-week rest period. 5-FU was administered on the first three days of each radiation therapy course. FAM (5-fluorouracil, adriamycin, mitomycin) was administered for maintenance chemotherapy. For pain control, complete relief was obtained in $22\% (4/18)$ of patients and partial relief in 39% (7/18). Median survival was 31 weeks. Pretreatment performance status was the only statistically significant prognostic factor.

Purpose: To determine the prognostic and predictive value of liver volume in colorectal cancer patients with unresectable liver metastases. Materials and Methods: Sixteen patients received whole liver radiotherapy (WLRT) between January 1997 and June 2013. A total dose of 21 Gy was delivered in 7 fractions. Results: The median survival time after WLRT was 9 weeks. In univariate analysis, performance status, serum albumin and total bilirubin level, liver volume and extrahepatic metastases were associated with survival. The mean liver volume was significantly different between subgroups with and without pain relief (3,097 and 4,739 mL, respectively; p = 0.002). Conclusion: A larger liver volume is a poor prognostic factor for survival and also a negative predictive factor for response to WLRT. If patients who are referred for WLRT have large liver volume, they should be informed of the poor prognosis and should be closely observed during and after WLRT.

Purpose: The purpose of this study was to determine the effect of nurses' pain experience on the inference of their patients' suffering. Method: Study subjects were sampled from 184 nurses who worked in general wards in one S university hospital located at Seoul. Nurses' pain experience consists of personal pain experience and professional pain experience. The Standard Measure of Inference of Suffering (Davitz & Davitz, 1981) was used for suffering inference measure, and patients' suffering which consists of physical pain and psychological distress. Result: Suffering inference scores of nurses without personal pain experience revealed a higher value than that of nurses with personal pain experience. But these differences were not statistically significant. The higher intense pain was experienced, the higher were suffering inference scores. This physical pain inference score was statistically significant(p=.044). Of the nurses who had personal pain experience, suffering inference scores of nurses with unrelieved pain experience revealed a higher value than that of nurses with relieved pain experience. Physical pain and psychological distress inference scores were statistically significant(p=.010, p=.006). Suffering inference scores of nurses without professional pain experience(internal medicine, general surgery, orthopedic surgery) revealed a higher value than that of nurses with professional pain experience. Professional pain experience of internal medical illness was statistically significant in psychological distress of internal medical illness(p=.044), and professional pain experience of orthopedic surgical illness was statistically significant in physical pain of orthopedic surgical illness(p=.027). Conclusion: Nurses who have experienced low pain intensity or good pain relief are inclined n to underestimate patient' pain. Although nurses who care for the same patient over a long time deal skillfully with that patient, nurses are inclined to underestimate that patients' pain. Nurses need to be aware of possible biases related to pain assessment as a result of pain experience.
