Depressive symptoms of patients using clean intermittent catheterization for neurogenic bladder secondary to spinal cord injury.

STUDY DESIGN: Prospective, cross-sectional study, based on cases of spinal cord injury (SCI). SETTING: Three outpatient medical departments in Seoul, Korea. OBJECTIVES: To assess depressive symptoms in patients on clean intermittent catheterization after SCI. METHODS: In total, 102 subjects (68 males and 34 females, mean age 39.5 with a range of 18-75 years) were included in the primary analysis. A control group of 110 was selected from the routine health checkup. All subjects completed the Beck Depression Inventory (BDI). RESULTS: For patients and controls, the average total BDI scores were 20.3+/-1.0 and 11.4+/-0.5, respectively (P<0.001). With regard to severity of depression among patient groups, three (3.0%) reported normal; four (3.9%) reported mild to moderate depression; 24 (23.5%) reported moderate to severe depression; and 71 (69.6%) reported severe depression. On the multivariate logistic regression analysis, a positive association with the risk of depression was observed in gender and type of catheterization. Female patients had a 3.8-fold higher risk (odds ratio (OR) 13.83; 95% confidence interval (CI) 1.42-10.31; P=0.008) of depression than male patients. In the same model, patients who were unable to perform catheterization independently had a 4.6-fold higher risk (OR 4.62; 95% CI 1.67-12.81, P=0.003) of depression than those who were able to perform self-catheterization. CONCLUSIONS: The results demonstrate that the patients with neurogenic bladder secondary to SCI have higher degrees of depression than normal population. In addition, our findings also suggest that depression is closely related to gender and patient's ability to perform self-catheterization.

Abdominal obesity, systolic blood pressure, and microalbuminuria in normotensive and euglycemic Korean men.

OBJECTIVES: To evaluate the relationship between abdominal obesity and microalbuminuria (MA) in normotensive, euglycemic Korean men. DESIGN: A cross-sectional study at a health screening center. SUBJECTS: A total of 1321 healthy, normotensive Korean men, aged 20-78 years, with a fasting plasma glucose level <100 mg/dl. MEASUREMENTS: Height, weight, and waist; systolic blood pressure (SBP); diastolic blood pressures (DBP); urinary albumin to creatinine ratio (ACR); fasting glucose, insulin, lipids, C-reactive protein (CRP), and white blood cell count. Waist circumference (WC) was used to indicate abdominal obesity and a single measurement of ACR was used to estimate MA. We also calculated body mass index (BMI) based on weight and height. RESULTS: Mean BMI, WC, and SBP were significantly higher in subjects with MA than in those without (24.8+/-4.1 vs 23.8+/-2.7 kg/m2, 86+/-9 vs 83+/-8 cm, and 115+/-5 vs 112+/-7 mmHg, respectively). Multiple logistic regression analyses showed that only WC and SBP were independent predictors of MA. CONCLUSION: WC and SBP were positively associated with MA in normotensive and euglycemic Korean men.

From data to knowledge--the Visible Human Project continues.

The U. S. National Library of Medicine (NLM) has long been a world leader in the archiving and distribution of the print-based images of biology and medicine. NLM has also been a pioneer in the use of computer systems to encode and distribute textual knowledge of the life sciences. NLM's Long Range Planning effort of 1985-86 foresaw a coming era where NLM's Bibliographic and factual database services would be complemented by libraries of digital images, distributed over high speed computer networks. The NLM Planning Panel on Electronic Imaging recommended that NLM should undertake the building a digital image library consisting of computerized tomography (CT) and magnetic resonance (MR) images, and cryosection images of a representative, carefully selected and prepared male and female cadaver--the "Visible Human Project ." The male and female Visible Human data sets are now being made available through a license agreement with the NLM. The data sets are supporting a wide range of educational, diagnostic, treatment planning, and commercial uses. The NLM, in partnership with other U.S. government research agencies has begun a three prong effort within the Visible Human Project to address: the creation of a new online, interactive, digital head-and-neck atlas; the development of a tool kit of computational programs capable of automatically performing many of the basic data handling functions required for using Visible Human data in applications; and the improved resolution of future Visible Human data sets through the reduction of the anatomical artifacts introduced by the methods used to stabilize and section the anatomical materials and the development of staining and wide-spectrum methods for increasing tissue contrast.

Home telecare system integrated with periodic health reminder and medical record & multimedia health information.

The necessity of home telecare system is growing due to increase in desire for health promotion owing to increase in chronic diseases, aged population and medical expenses. Already, we computerized patient's data and offer periodic health reminder to patients for health promotion by using Life-time Health Monitoring Program (LHMP). Our study connected LHMP to the Web on internet by CGI as an electronic medical record; enabling reference to patient's medical records anywhere. The study also made possible video teleconsultation and constructed multimedia database to provide health-related information to the patients. On these bases, a flow chart was developed using the home telecare to practice manage patients with chronic diseases, old patients, and the handicapped. Further standardization in data, establishment of law bases for home telecare system, development of rules for medical fees and active utilization of biomedical telemetry will be needed to extend home telecare system.

Features for a B-ISDN telemedicine system and its application.

Telemedicine technology is emerging as a new way of medical practice. It will provide more cooperative activity between departments and more comfortable access for disabled patients home. We developed two types of telemedicine system: a telediagnosis system and a home care system. Our telemedicine application is aimed to be run on the broadband-integrated services digital network (B-ISDN). The legacy network is also considered. The user interface is designed to help doctors to communicate easily. The key elements of telemedicine systems are user friendly interface, medical multimedia database design highly refined display technique.

Standardization of the nationwide health examination in Korea.

The Korea Medical Insurance Corporation has held the periodic Health Examination for the public servants and teachers from 1977 as a nationwide health preventive task. But the Health Examination result is not computerized rather than paperwork, so the use of the Health Examination is limited and the results of Health Examination can not be stored or interchangeable between hospitals or health examination centers in this system. So we planed the Standardization of the Nationwide Health Examination project and developed the Health Examination computer program in 1996. The object of standardized program is to contribute to cost-effective analysis of each item or other studies about the factors influences development of diseases. And now, an Exhibition work for the standardization is being held with the Health Examination computer program. At the ending of the Exhibition work, we will evaluation and revision the computerized program for standardization process.

Information system for a periodic examination and health promotion center.

The periodic examination and health promotion center (PEHPC) in Seoul National University Hospital has developed and adopted an information system supported by computers which use an electronic medical record to improve the quality of patient care, advance the science of medicine, lower health care costs, and enhance the education of health care professionals. This information system adopted the concept of incomplete and evolutionary systems to conduct the pursuit of practicalness and efficacy. It has increased efficiency to save costs and to enhance the quality of the medical service. It has also activated clinical research due to ease of managing data. We are also preparing for telecare. Telecare and WWW-using information system is postponed because the protection of a patients privacy is not established.

Screening for gestational diabetes mellitus. Use and accuracy of capillary blood glucose measured with a reflectance meter.

Screening for gestational diabetes mellitus by a 1-hour glucose challenge test is recommended for all pregnant women between 24 and 28 weeks of pregnancy. Measurement of capillary blood glucose with a reflectance meter is well known and considered to be accurate, reliable, less costly, and more convenient than the laboratory test of plasma glucose. One hundred eighty-one pregnant women were tested with both a 1-hour glucose challenge test by capillary blood glucose and a 3-hour glucose tolerance test by venous plasma glucose. The diagnosis of gestational diabetes mellitus was made by the standard criteria on the 3-hour glucose tolerance test. The receiver operating characteristic curve was used to determine the optimum threshold value. There were seven cases of gestational diabetes mellitus detected during this study period, producing an incidence of 3.9%. The threshold value for the 1-hour glucose challenge test by capillary blood glucose was 9.0 mmol/L (163 mg/dL); the test has a sensitivity, specificity, predictive value, and likelihood ratio of 0.857, 0.868, 0.207, and 6.48, respectively. This test was at least as accurate as a 1-hour glucose challenge test by venous plasma glucose. Given its advantages, such as lower cost, simplicity, better patient acceptance, and immediate availability of the result, capillary blood glucose testing should be considered for screening of gestational diabetes mellitus in the office setting.

[Clinical experience with cefbuperazone in complicated urinary tract infection].

Cefbuperazone (CBPZ) was administered to inpatients with complicated urinary tract infections (UTI) at our department. Clinical efficacy and safety were evaluated in 22 chronic cases by the criteria for evaluation of clinical of antimicrobial agents on urinary tract infection. Overall clinical efficacy was excellent in 8 cases, moderate in 9 cases and poor in 5 cases with an effectiveness rate of 77%. Twenty-four of the 34 strains isolated from the patients were eradicated and eradication rate was 71%. Neither subjective nor objective adverse reactions were observed. Abnormal changes in laboratory tests were found in 9 patients, but were probably not related to CBPZ administration. Judging from these results, CBPZ is considered to be an effective and safe antibacterial for the treatment of complicated UTI.
