OBJECTIVES: An accurate estimation of cancer patients is the basis of epidemiological studies and health services. However in Korea, cancer patients visiting out-patient clinics are usually ruled out of such studies and so these studies are suspected of underestimating the cancer patient population. The purpose of this study is to construct a more complete, hospital-based cancer patient registry using multiple sources of medical information. METHODS: We constructed a cancer patient detection algorithm using records from various sources that were obtained from both the in-patients and out-patients seen at Asan Medical Center (AMC) for any reason. The medical data from the potentially incident cancer patients was reviewed four months after first being detected by the algorithm to determine whether these patients actually did or did not have cancer. RESULTS: Besides the traditional practice of reviewing the charts of in-patients upon their discharge, five more sources of information were added for this algorithm, i.e., pathology reports, the national severe disease registry, the reason for treatment, prescriptions of chemotherapeutic agents and radiation therapy reports. The constructed algorithm was observed to have a PPV of 87.04%. Compared to the results of traditional practice, 36.8% of registry failures were avoided using the AMC algorithm. CONCLUSIONS: To minimize loss in the cancer registry, various data sources should be utilized, and the AMC algorithm can be a successful model for this. Further research will be required in order to apply novel and innovative technology to the electronic medical records system in order to generate new signals from data that has not been previously used.

Purpose:
We report three cases of asymptomatic pseudo-optic discs in chorioretinal colobomas highlighted on visual fields patterns.Case summary: (Case 1) A 36-year-old man was found to have a pseudo-optic disc below the optic nerve with a relatively intact neurosensory retina over the lesion. There were no obvious abnormalities on the visual field test, so he underwent no treatment and was followed up every 6 months. (Case 2) A 37-year-old woman diagnosed with glaucoma had abrupt convergence of the neurosensory retinal layers on the boundary of the pseudo-optic disc and a focal retinal nerve fiber layer defect in the inferior sector. An antiglaucoma eyedrop was used to manage the superior hemifield defect, and no significant progression was observed in the structural and functional tests during the 5-year follow-up. (Case 3) A 57-year-old man had a pseudo-optic disc with diffuse retinal nerve fiber layer atrophy in both the superior and inferior sectors. The pseudo-optic disc had protruded into the vitreous cavity. Antiglaucoma eyedrops were used to manage both the superior and inferior hemifield defects, and no significant progression was observed using the structural and functional tests during the 6-year follow-up period.
Conclusions
Various visual field results may occur with pseudo-optic discs in chorioretinal colobomas depending on the status of residual retinal tissues and underlying glaucoma. Further evaluations and management options should be considered according to the patient’s condition.

BACKGROUND: High-risk group neuroblastoma (HRNB) is one of the most incurable diseases in pediatric oncology field. This report explores the effectiveness, safety and feasibility of triple high dose chemotherapy followed by autologous stem cell transplantation (HDCT/ASCT) in contrast with single HDCT/ASCT for HRNB.METHODS: From Jan. 2001 to Dec. 2009, 25 patients newly diagnosed as HRNB have been analyzed. This study is a retrospective analysis with the medical records of these 25 HRNB patients.RESULTS: Eleven (44%) and the other fourteen (56%) patients were treated with single HDCT/ASCT and triple HDCT/ASCT, respectively. The 5-year event-free survival (EFS) of the whole group in HRNB is 37.2+/-10.0%. The 5-year EFS of single HDCT/ASCT and triple HDCT/ASCT were 27.3+/-13.4% and 46.8+/-13.8%, respectively (P=0.38). Between two groups, there were no statistically significant differences including clinical features, outcome, transplantation-related toxicities, and short-term/long-term complications.CONCLUSION: Triple HDCT/ASCT group showed similar transplantation-related toxicities and long-term complications when compared to single HDCT/ASCT group. We need more exploration to conclude the triple HDCT/ASCT as an optimal treatment for HRNB patients.

Objective:To evaluate the application value of bismuth shielding combined with organ tube current modulation (X-care) in brain CT scanning by measuring the radiation dose of sensitive organs.Methods:The head and neck phantom was scanned with Siemens dual source CT at the same volume CT dose index (CTDI vol) by X-care, bismuth shielding and x-care combined with bismuth shielding, and by dual energy CT angiography (DE-CTA) with and without bismuth shielding. The CT values of cerebral vessels, adjacent brain tissues and cerebrospinal fluid and image noise were measured, and the contrast noise ratio of cerebral vessels and brain parenchyma was calculated. Organ dose equivalent ( HT) was calculated by placing thermoluminescent personal dosimeter (TLD), and CTDI vol and dose length product (DLP) were recorded after each scan. Results:Under the same CTDI vol, the mean values of HT, lens with X-care, Bi shielding and X-care combined with Bi shielding were(37.89 ± 2.00), (42.20 ± 2.96) and (28.21 ± 1.31) mSv, respectively, significantly lower than those of conventional sequence scanning( F=186.52, P<0.05). The values of HT, thyroid with Bi shielding and X-care combined with Bi shielding were (0.77 ± 0.07) and (0.89 ± 0.08) mSv, lower than those of routine brain scan and X-care( F=103.26, P<0.05). The values of HT, lens and HT, thyroidof DE-CTA with bismuth shielding were (11.56 ± 1.04) and (0.32 ± 0.03) mSv, respectively, significantly lower than those without bismuth shielding( t=5.07, P<0.05). There was no significant difference in noise and CNR in routine brain scan between with and without X-care, bismuth shielding and X-care combined with bismuth shielding. There was no significant difference in noise and CNR in dual energy CTA scanning between with and without Bi shielding. Conclusions:Using bismuth shielding and organ tube current modulation, we can significantly reduce organ dose of lens and thyroid during brain CT scanning without sacrificing the image quality.

The objective of this study was to examine job satisfaction status and its related factors among dietitians working in hospitals. A survey questionnaire was sent to dietitians working in tertiary, general, and convalescent hospitals in Korea. The study sample hospitals included all tertiary hospitals (n=43), and the sample of general hospitals (n=114) and convalescent hospitals (n=240) was randomly selected using a stratified sampling method. A total of 665 dietitians completed the survey questionnaire. The questionnaire included 27 job satisfaction questions on task, stability.vision, working conditions, and relationship areas, and the questions on task improvement need. The job satisfaction scores in all four areas ranged from 2.53/5.00 to 3.89/5.00, implying generally low job satisfaction level in hospital dietitians. The job satisfaction levels in the convalescent hospital group were significantly lower compared to those in the tertiary and general hospital groups. Whereas job satisfaction levels of tertiary and convalescent hospital groups did not differ by number of beds, those of the general hospital group increased significantly with the number of beds for all four areas. Multivariate regression analysis results showed that hospital type was a significant predictor of job satisfaction level for all four areas. Job satisfaction of relationship area was also significantly affected by the number of beds, whereas that of working conditions was influenced by annual income and working experience. The study findings provide useful information in planning clinical dietitians' optimal supply outlook for the improvement of clinical nutrition services.

The purpose of this study was to evaluate nurses' perception of clinical nutrition services. A cross-sectional survey design was performed. The research was accomplished by using questionnaires developed for this study and administered from September 12 to December 31, 2013 to 343 nurses at 43 tertiary hospitals and 20 general hospitals. The percentage of nurses who recognized clinical nutrition certificate as issued from nation was 27.8%. The mean scores of perceived usefulness on clinical nutrition services was 4.23/5.00, whereas that of perceived implementation was 3.76/5.00. The mean scores of necessity of disease-specialized clinical dietitian at capital hospitals were significantly higher for obesity (P<0.01), cancer (P<0.05), and infant & childhood disease (P<0.01) than at local hospitals. The rates of nurses' experience in group education on cancer at capital hospitals (21.7%) was significantly higher than that at local hospitals (10.3%) (P<0.05). The mean scores of perceived importance of clinical nutrition services were 4.46/5.00 for 'group nutrition education', 4.46/5.00 for 'individual consultation', and 4.40/5.00 for 'nutrition management for enteral nutrition (EN) patients'. The most common reason why clinical nutrition services are important was 'improving malnutritional status'. To activate clinical nutrition services especially at local hospitals, clinical dietitians should give systematic assistance to patients and also institutional supports are needed.

The purpose of this study was to investigate the status of clinical nutrition services provided at tertiary hospitals and general hospitals in Korea. In total, 157 questionnaires were distributed to the departments of nutrition at hospitals on September 2013. The results of this study are as follows. The median number of beds was 607 and average length of stay was 8 days. 63.1% of dietitians had over 5 years of career experience. Nutritional screening rate was 97% in tertiary hospitals but only 67.2% in general hospitals (P<0.001). The rate of equipment with computerized nutritional screening system was 100% in tertiary hospitals but 71.9% in general hospitals (P<0.001). Hospitals with the best regarding nutritional care were hospitals accredited by JCI (Joint Commission International). On the other hand, hospitals not accredited by the JCI but KOIHA (Korea Institute for Healthcare Accreditation) showed the lowest performance rate of nutritional care. Nutrition support teams (NSTs) were established in all tertiary hospitals but in only 73% of general hospitals (P<0.001). The rate of actively operating NSTs was 89% in tertiary hospitals but only 62% in general hospitals (P<0.001). There is a need to provide proper standardized clinical nutrition services as a primary treatment and we observed large variations in the quality of nutritional service between hospitals. Therefore, local solutions are needed to implement nutritional programs and policies for improved service and care.
