Low back pain patients an controls of shipyard workers were surveyed between June 1995 and september 1995 to identify risk factors of industrial low back pain. The patients were 17 male workers who had got medical treatment for over 3 days because of industrial back pain controls were 51 male workers who had not have musculoskeletal disorder for one year before the survey. By univariate analysis, the workers who did overtime work 4 times or more for the last 2 weeks showed odds ratio of 3.67 on low back pain with the workers who did less overtime work. Carrying heavy materials was also associated with the low back pain and the odds ratio increased with the increase of carrying weight. work space and work posture were not associated with the low back pain significantly. The welder had higher odds ratio than the other workers on low back pain. The duration of employment and job satisfaction did not affect the risk of low back pain. Multiple logistic regression analysis showed that frequency of overtime work for the last 2 weeks and carrying heavy materials among the risk factors were associated significantly with the low back pain. We found that important risk factors of low back pain of shipyard workers are work intensity factors such as overtime work and carrying heavy weight.

Plain radrographs of thirty nine patients with giant cell tumor of long bone and CT scans of twenty patients among the thirty patients were reviewed retrospectively to evaluate the frequency and significance of sclerosis of the tumor margin. The sclerosis of the tumor margin was observed on plain radiographs in thirteen patients(33.3%) and they were located either on epiphyseal or on both epiphyseal or metaphyseal portion of the tumor. The authors concluded that the giant cell tumor should not be excluded from the differential entities eventhough the tumor has the marginal sclerosis.

Despite significant advances in obstetric and pediatric health care, Streptococcus agalactiae(Lancefield group B β-hemolytic Streptococcus, GBS) remains one 91 the most prevalent and devastating pathogens in peripartum women and their newborn infants. It may cause urinary tract infection, chorioamnionitis and endometritis, bacteremia, and cesarean wound infection in the peripartum period. It was Pasteur who first identified microbes in the blood and lorchia of septic women. After that, in 1938 the isolation of S. agalactiae from three mortally ill women was reported, thereby implicating it as another cause of puerperal sepsis. S. agalactiae is now one of the most common causes of neonatal sepsis and meningitis in the United States. However, in Korea there have been only twenty-three cases of neonatal meningitis and/or sepsis due to group B β-hemolytic streptococcus reported. Recent studies have noted other serious infections in adults, including bacteremia, pneumonia, cellulitis, osteomyelitis, meningitis, and endocarditis. In Korean adults no case of pneumonia due to S. agalactiae has been reported till now. As minimal inhibitory concentration of penicillin was reported to be higher for S. agalactiae than for S. pyogenes, minimal inhibitory concentration of penicillin for S. agalactiae should be tested. Herein we describe the course of a case of S. agalactiae pneumonia and bacteremia in a 74-year-old diabetic man, and we review the literatures.

Legg-Perthes' disease, as avascularity of the femoral head that often arises in the child of a particular age group, is a serious disease of which the frequency is more than the osteochondroses of the other part, and the cause of Legg-Perthes disease is obscure up to now, but the pathogenesis and, pathology are more clearly understood. Twenty patients with Legg-Perthes disease were managed at the department of Orthopaedic Surgery of Hanyang University hospital from May, 1972 till September, 1977 and were studied according to the method of Catterals classification arid arthrogram. The following conclusion were made. 1. The age group with the highest frequency was that from 6 to 9 years (40%) and the ratio of male: female was 6: 1. 2. The stage of disease s progress when patient went to hospital was almost fragmentation stage as 17 persons of the whole. 3. By arthrogram Spherical form of femoral head was 15%; Round form 45%; Flatten form 40%. 4. The longer the period from onset to beginning of treament was the more femoral head flattened. 5. There was the most number of patient as 13 persons of the whole wearing abduction internal rotation brace. 6. From the view point of arthrogram the more spherical the femoral head was the better the prognosis was; otherwise the worse.

We have investigated a series of 45 acute traumatic hemarthrosis of the knee between Jan. 1989 and Jan. 1993 at National Medical Center. All the patients who had normal findings on plain X-ray with hemarthrosis underwent arthroscopic examination under anesthesia. The arthroscopic results were as follows. 1. There were 14 cases(31%) of anterior cruciate ligament(ACL) tear, a case(2%) of avulsion fracture of tibial spine, 13 cases(29%) of lateral meniscus tear, 8 cases(18%) of medial meniscus tear, a case(2%) of osteochondral fracture of patella, and 8 cases(18%) showed no specific injury of internal structure. 2. The positive predictive value of Lachman and anterior drawer tests under anesthesia was 93% and 92%, respectively. 3. The positive predictive value of McMurray tests for medial and lateral menisci was 33% and 64%, respectively. 4. We concluded that a traumatic hemarthrosis indicated a significant knee injury and arthroscopy allowed a more accurate diagnosis of injury to joint structure.

PURPOSE: To implement evidence-based nursing, it is important to know where and how to find the best available evidence. This study was conducted to identify the results of a search from Ovid MEDLINE and to compare the results from Ovid MEDLINE with those from PubMed MEDLINE. METHODS: Four different approaches via Ovid MEDLINE were used to search for guidelines on preventing catheter-associated urinary tract infections. Outcomes of this study were the number of records and relevant literature, and the sensitivity and precision of the search methods via Ovid MEDLINE. RESULTS: The number of retrieved items ranged 23 to 6,005 and that of relevant studies, 5 to 8 of 8. Simple searches resulted in the highest sensitivity of 100.0%. When using MeSH terms and limits feature, the precision was highest (21.7%) among four approaches for literature searches. Simple searches in Ovid had higher sensitivity and lower precision than those in PubMed. CONCLUSION: Simple searches in Ovid may be inefficient for busy clinicians compared to PubMed. However, to ensure a comprehensive and systematic literature search, using Ovid MEDLINE in addition to PubMed is recommended.
