PURPOSE: To evaluate the clinical symptoms and the associated intra-articular disorders of the polpliteal cyst. MATERIALS AND METHODS: We studied 56 patients, 60 cases of the popliteal cysts which. Had been treated with excision of the cyst after arthroscopy between May 1991 and February 2000. Arthroscopic findings and clinical results of the patients who had popliteal cyst were evaluated. RESULTS: Forty nine patients of the sixty patients of who had popliteal cyst showed intra-articular disorders. Tear of the meniscus and patello-femoral arthrosis with cartilage lesions were the most frequent intra-articular lesions. In 4 cases, recurrence of the popliteal cyst was noted. Two patients had tear of the meniscus and two had no intra-articular disorders. CONCLUSION: This study revealed that popliteal cysts frequently combined with intra-articular disorders. Arthroscopy of the knee joint seems worthwhile method for the patients who had popliteal cyst

BACKGROUND: The occurrence of an outbreak of food-borne infectious disease requires a hospital to do extended role. There has been no report of an outbreak and an outbreak management of food-borne infectious diseases in a hospital. Therefore, this report of an outbreak and management of Shigellosis in the hospital would help others to manage further cases. METHODS: This was a descriptive study for an infection control program for food-borne infectious diseases in a hospital. RESULTS: There was a shigellosis outbreak at a university hospital in Seoul between December 3 and 30, 2001, Five hundred eighty four were affected, of which 81 cases were suspected and 86 cases were confirmed Shigella sonnei in fetal culture. The source of infection was identified as a lunch box or seaweed rolled rice that was contaminated and was supplied from the S-catering facility. The infection control team had developed the various strategies to control the outbreak and implemented them. The strategies included an epidemiology investigation, the removal of infection sources, medical treatment and isolation of patients, education and management of public relationship, environmental control, withdrawal of medical students' training, prevention and control of asymptomatic cases, intensive care unit strong financial support, analysis and management various data and the construction of cooperation and reporting system with the public health system CONCLUSION: This outbreak was controlled by effective team approach. The effective management of an outbreak of food-borne infectious diseases requires a systematic infection control, public relationship strategies for the reputation of the hospital, and the cooperation with a public health system.

The general concept and initial approach to syncope patients has been mentioned in the general sections. This special sections have been described the characteristics, diagnosis, and treatment with patient education for the each syncope. It has been described in order of reflex syncope, orthostatic hypotension, postural orthostatic tachycardia syndrome (POTS), cardiac syncope, and unexplained syncope. Several clinical issues will have been dealt with in special issues. Neurological assessment is added when the patients were diagnosed with psychogenic pseudosyncope (PPS). Although many childhood syncope caused by reflex syncope, they are also presented as syncope caused by arrhythmic events in patients with congenital heart disease. In the elderly patients, syncope is because of not only a single cause of syncope but a combination of various conditions. In case of a syncope patient visiting the emergency department, a standardized systematic approach will be required to determine whether hospitalize the patient according to the risk of recurrence and the needs for the syncope management unit. We also mention recommendations on the limits of driving, exercising and social life style that are relevant to syncope in all patients. In this guideline, we reviewed the Korean published literatures and European/American guidelines on syncope. We, writing and publishing committee for evaluation and management guidelines of syncope in the Korean Society for Holter and Noninvasive Electrocardiography (KSHNE) under the Korean Heart Rhythm Society (KHRS) are very pleased to be able to publish this guideline. We also hope this guideline will be a good support to manage the syncope patients and a useful trigger for further research in Korea.

Syncope is a very common symptom that occurs in all age groups, especially in adolescents and elderly people. The cause of syncope is very diverse, and patients with syncope visit various medical departments such as general medicine, cardiology, neurology, and emergency medicine. If we do not perform appropriate diagnostic tests based on detailed history of syncope, we may have some difficulty to identify the cause of syncope. Failure to identify the cause of syncope can lead to physical trauma due to recurrence of syncope or may increase the risk of cardiovascular events in the future. However, there is no Korean guidelines for the diagnosis and treatment of syncope yet. Considering these circumstances in Korea, we prepared writing and publishing committee for evaluation and management guidelines of syncope in the Korean Society for Holter and Noninvasive Electrocardiology (KSHNE) under the Korean Heart Rhythm Society (KHRS). In this guideline, we reviewed the Korean published literatures and European / American guidelines on syncope.

PURPOSE: This study investigated the differences in the profile of IgE-binding components between Dermatophagoides pteronyssinus (Dp) and Dermatophagoides farina (Df) in respiratory allergic patients sensitized to Dp/Df. METHODS: Eighteen patients with respiratory allergic diseases having higher levels of serum specific IgE to Df compared to those to Dp (>twice) were enrolled. IgE-immunoblot analysis using Dp and Df extracts were used to compare the IgE binding components. Study subjects were classified into 2 groups according to the results of IgE-immunoblot analysis: 6 subjects having IgE-binding components to group 1 and 2 allergens (group B) and 12 subjects not having them (group A). RESULTS: Group A subjects were older (47.92±8.51 vs. 35.50±11.10, P=0.039) and males were dominant (75% vs. 0% P=0.009). IgE-immunoblot analysis demonstrated that all the group B subjects had IgE bindings to 2 major components, 14 and 25 kDa, while group A subjects had IgE bindings to high-molecular weight components ranging from 60-98 kDa. The enzyme-linked immunosorbent assay inhibition test showed a significant inhibition with additions of Df, not with Dp in group B subjects. Serum specific IgE levels to Dp and Df were significantly higher in group B than in group A, while its ratio (Df to Dp) was significantly higher in group A. No differences were noted in clinical parameters, total IgE, or eosinophil cationic protein levels. CONCLUSION: Heterogeneity of IgE binding patterns to Dp and Df extracts was noted according to the ratio of serum specific IgE (Df/Dp).

OBJECTIVES: The aim of this study was to examine the effect of depression, impulsivity, and resilience on smartphone addiction in university students. METHODS: A total of 322 students from two universities in Seoul were enrolled in this study. Participants were divided into a risk user group and normal user group according to results using the Korean smartphone addiction scale. We additionally surveyed smartphone use patterns of the participants. The Beck Depression Inventory (BDI), Barratt Impulsiveness Scale (BIS), and Conner-Davidson Resilience Scale (CD-RS) were also used for measurement of the participants' severity of depression, impulsivity, and resilience. RESULTS: The risk user group spent more time using a smartphone on weekdays than the normal user group. The risk user group showed significantly higher scores on BDI, BIS than the normal user group. The risk user group showed significantly lower scores on CD-RS than the normal user group. Results of multiple regression analysis showed that impulsivity was a significant factor affecting smartphone addiction in university students. CONCLUSION: These results suggest that smartphone addiction is influenced by impulsivity. Students with high impulsivity may be vulnerable to smartphone addiction. Further research regarding the underlying mechanisms of these associations is needed.

Accessory spleen can be mistaken as a gastric subepithelial mass, and may not be differentiated in CT or endoscopic ultrasonography (EUS). A gastric subepithelial mass was detected on routine endoscopy in a 39-year old woman with history of splenectomy. In subsequent CT and EUS, the subepithelial mass was located on the fourth layer of the stomach. To make a definite diagnosis, EUS-guided fine needle aspiration (FNA) was performed, and a splenic tissue was demonstrated in histologic examination. EUS-guided FNA can be beneficial in the diagnosis of accessory spleen which mimics a gastric subepithelial mass.

PURPOSE: Stereotactic ablative radiotherapy (SABR) is an effective emerging technique for early-stage non-small cell lung cancer (NSCLC). We investigated the current practice of SABR for early-stage NSCLC in Korea. MATERIALS AND METHODS: We conducted a nationwide survey of SABR for NSCLC by sending e-mails to all board-certified members of the Korean Society for Radiation Oncology. The survey included 23 questions focusing on the technical aspects of SABR and 18 questions seeking the participants' opinions on specific clinical scenarios in the use of SABR for early-stage NSCLC. Overall, 79 radiation oncologists at 61/85 specialist hospitals in Korea (71.8%) responded to the survey. RESULTS: SABR was used at 33 institutions (54%) to treat NSCLC. Regarding technical aspects, the most common planning methods were the rotational intensity-modulated technique (59%) and the static intensity-modulated technique (49%). Respiratory motion was managed by gating (54%) or abdominal compression (51%), and 86% of the planning scans were obtained using 4-dimensional computed tomography. In the clinical scenarios, the most commonly chosen fractionation schedule for peripherally located T1 NSCLC was 60 Gy in four fractions. For centrally located tumors and T2 NSCLC, the oncologists tended to avoid SABR for radiotherapy, and extended the fractionation schedule. CONCLUSION: The results of our survey indicated that SABR is increasingly being used to treat NSCLC in Korea. However, there were wide variations in the technical protocols and fractionation schedules of SABR for early-stage NSCLC among institutions. Standardization of SABR is necessary before implementing nationwide, multicenter, randomized studies.
