To compare the results of the chemonucleolysis and the automated percutaneous lumbar discectomy(APLD) for symptomatic lumbar disc herniation, retrospective study of 19 chemonucleolysis and 20 APLD was done from July, 1984 to February, 1993. Number of male patients was 23 and female 16. The patients ranged in age from 14 to 56 years. L4-5 was the most commonly involved level comprising 73.6%, and 2 level involvement was 20.5%. Clinical results were evaluated according to Mcnab s criteria. Excellent and Good result were 31.6% and 47.3% in chemonucleolysis with an average follow up period of 6.2 years, and those were 35% and 45% respectively in APLD with an average follow up period of 18.7 months. Among 19 chemonucleolysis, there were loss of disc height in 8, and lateral recess stenosis in 1. Among 20 APLD, there were loss of disc height in 2, and nerve root irritation symptoms in 2. Chemonucleolysis and APLD have a low morbidity, can be performed under the local anesthesia and are simple, rapid and less traumatic procedure.

OBJECTIVES: This research aimed to know the actual condition and problems of medical information protection at a workplace with the target of industrial health care managers of small and medium-sized enterprises. METHODS: A self-administered questionnaire was given to industrial health-care managers of 216 enterprises from March 15 to May 17, 2010. The questionnaire was produced by referring to the Act on Personal Information Protection of Public Institutions, etc. This research evaluated agreement of cognition and practice according to 10 items of medical information protection using kappa and cross-analysis of significant factors between cognition and practice of medical information protection and general characteristics. RESULTS: Cognition about medical information protection appeared to be 85.4-97.1% and its practice appeared to be 44.1-95.3%, so practice was lower than cognition. In addition, the agreement of cognition and practice appeared significantly low (kappa 0.082-0.387). The practice of medical information protection tended to be lower when the managers were older and held a higher job title. Health examination results were being delivered only to workers except for an employer (94.2%), but there were many industrial health-care managers who felt discomfort about their work in group occupational health-care systems (58.1%). CONCLUSIONS: The practice of protecting medical information by industrial health-care managers was clearly lower than the cognition. Therefore, introduction of educational programs about personal information protection and provision of an independent place for group occupational health care service is urgent. In addition, in order to use the health examination results conveniently in group occupational health services, an institutional complement is necessary.
