Recently with the development in computer technology and its communication system, many changes have come to the medical field. For example, Picture Archiving and Communication System(PACS) has been used in the medicine experimentally. But this system needs high cost and instrument, so this system is not used in personal generally. Our hospital established the medical forum for health and medical counseling in Computer communication network called HITEL. We analysed the questions about urologic problem especially from Sep, 1994 to Jan, 1997. Most of questions are related to external genitalia and sexually transmitted diseases and most of users were in their 2nd, 3rd and 4th decades and male-predominant. In conclusion, medical counseling using PC communication is an effective method especially in urologic field.

Clinically, evaluation and procedures using ultrasound are expanding in the field of neuromusculoskeletal disorders, and ultrasound is also actively used for hip and thigh pain. This review delineates the normal ultrasound findings of lateral and posterior aspects of the hip joint and thigh. Furthermore, it covers ultrasound findings of commonly occurring soft tissue diseases and nerve entrapment, along with ultrasound-guided injections.

Syringomyelia is a relatively uncommon, chronic, slowly progressive, degenerative process characterized by cavitation and gliosis within the substance of the spinal cord and/or the medulla. There have been only a few case reports in Korea. The authors reviewed 17 patients with syringomyelia diagnosed by delayed metrizamide spinal CT and/or MR imaging at Seoul National University Hospital from January, 1983 to June, 1987. Eleven were male and the age of onset was less than 40 in 16 (mean 23.4). The mean duration of symptoms was 87.1 months (range 3-276). Clinical features were similar to classical cases except sphincter involovement and abnormal sweating were more common in this report. The syrinx cavity which showed dye collection within spinal cord in delayed metrizamide spinal CT and low signal intensity in T1 weighted MR imaging was located mainly at cervicothoracic junction. The causes were the hindbran abnormality in 5, intramedullary cord tumor in 5, trauma in 3, adhesive arachnoiditis in 1 and unknown in 3. The cases with sensory dissociation had shorter duration of symptoms than those without sensory dissociation and showed normal results in SEPs study. Eleven patients were treated surgically and nine of them improved. MRI and SEPs are thought to be good aids for the understanding of the mechanism and course of syringomyelia.

Objective: To determine the effects of an integrated training device for strength and balance on extremity muscle strength, postural balance, and cognition in older adults using a combination with various rehabilitation training games, in which balance, strength, and cognitive training were configured in a single device. Methods: This prospective study included 20 healthy participants aged 65–85 years. Participants trained for 30 minutes daily, 3 days weekly, for 6 weeks with an integrated training device for strength and balance (SBT-120; Man&Tel Inc., Gumi, Korea). Main outcomes were measured using the Korean Mini-Mental State Examination (K-MMSE), Korean version of the Montreal Cognitive Assessment (K-MoCA), Timed Up and Go Test (TUG), Functional Reach Test (FRT), Berg Balance Scale (BBS), and Manual Muscle Test. Measurements were taken at three time points: T0 (pretreatment), T1 (immediately after treatment), and T2 (4 weeks after treatment). Results: All 20 patients completed the training, and TUG, FRT, and BBS scores significantly improved at T1 and T2 compared to T0. Mean TUG scores decreased by 0.99±2.00 at T1 and 1.05±1.55 at T2 compared to T0. Mean FRT scores increased by 6.13±4.26 at T1 and 6.75±4.79 at T2 compared to T0. BBS scores increased by 0.60±0.94 at T1 and 0.45±1.15 at T2 compared to T0. Moreover, muscle strength and cognition (K-MMSE and K-MoCA scores) increased after training. Conclusion Our findings suggest that an integrated training device for strength and balance can be a safe and useful tool for older adults.

BACKGROUND: Standardized management and surveillance at a national level is essential to maintain blood product safety. Officials of the Korean Division of Human Blood Safety Surveillance, Korea Centers for Disease Control and Prevention, and Korean laboratory transfusion medicine specialists, currently participate as inspectors in the Korean National Blood Inspection Program for Blood Establishments. However, lack of definitive guidelines and absence of standardized inspector training programs compromise the goal of objective and consistent safety management results. In this study, we propose establishment of written inspection guidelines and a clearly documented accreditation training program. METHODS: Inspector training programs in the US and EU were reviewed online and the results of the Korean National Blood Inspection in our country performed during last 4 years were analyzed. RESULTS: We suggested inspection guidelines for every question of inspection checklists. Also, for the questions similar to those of Laboratory Accreditation Program of the Korean Society for Laboratory Medicine (KSLM), guidelines were proposed as 'Results of Laboratory Accreditation Program of the KSLM could be concerned if inspected laboratory obtained 2 year accreditation lately'. We suggest an 18hr-basic training program composed of lectures, e-learning and a visit to a blood center, as well as 12hr-continuing courses, should be established. CONCLUSION: To establish the Blood Inspection Program in a more systematic manner, thorough management and training of inspectors are essential. We expect the guidelines and training program for inspectors, suggested in our study, will be the cornerstone for creating a more professional quality management system and further ensure the safety of the national blood management system.

PURPOSE: In order to evaluate the clinical relevance of angiogenesis in patients with gastric cancer, we investigated the microvessel count in gastric cancer tissues and compared the results with several clinicopathologic factors and prognosis. MATERIALS AND METHODS: A total of 256 patients with gastric cancer who underwent curative surgery were included in this study. Microvessel count was determined by im-munohistochemical staining using monoclonal antibody against factor VIII-related antigen. RESULTS: The statistical significance between the microvessel count and clinicopathologic factors (age, sex, tumor invasion, lymph node involvement, histologic type) was analized. The tumor stage and histologic type were correlated with microvessel count. And also there was statistical significance with survival rate and recurrence-free survival rate between high (microvessel count> or =42) and low angiogeneic group (microvessel count< 42). The Cox's proportional hazard model showed that stage, histologic type, angiogeneic score were one of the significant and independent prognostic variables. CONCLUSION: The tumor angiogenesis of gastric carcinoma may be independent prognostic factor for predicting recurrence and survival.

PURPOSE: To compare the variable inflammatory parameters of acute pyelonephritis patients treated with inpatient therapy at 13 hospitals, according to the age and gender distributions. MATERIALS AND MATHODS: A total of 3,544 medical records of patients with confirmed acute pyelonephritis, and admitted to hospital between January 2000 and December 2005, were retrospectively analyzed. RESULTS: The mean age of the patients was 43.2+/-16.2 years old, with a male:female ratio of 1 : 5.1. The average duration of hospital admission was 7.9+/-5.3 days. Underlying diseases were found in 23.0% (749/3,252 patient), largely due to diabetes (35.1%). Radiological abnormal findings were found in 13.7%. The leukocyte count, ratio of segmented form, erythrocyte sedimentation rate (ESR), c-reactive protein, pyuria, positive blood culture, positive urine culture were 11,014+/-5,778/mm(3), 74.8+/-14.5%, 44.0+/-32.0 mm/hr, 12.4+/-9.3mg/dl, 83.9%, 10.5% and 46.7%, respectively. E. coli grow in 79% of the urine culture positive patients. In a comparison of 3 age groups (<40 years, 40-60 years, >61 years), the elderly patients had a greater number of underlying diseases and more pathogens in cultured blood. When divided into males and females, the elderly male patients had more pathogen in cultured urine, but contrary to the male patients, the elderly female patients had elevated leukocyte count and erythrocyte sedimentation rate. Also, the old patient group had more resistance to ampicillin when they had E. coli as the uropathogen (p=0.021). Patients with higher ESR required longer hospital admission periods. CONCLUSIONS: It was found that variable clinical parameters of acute pyelonephritis patients treated with inpatient therapy differed according to both gender and age group in Korea. Therefore, these factors should be taken into account in the treatment plan.
