Background
: Osteoporosis is becoming major health problem in old age and menopausal women, and osteoarthritis is most common joint disease in both ages. The inverse relationship between osteoporosis and osteoarthritis was first noticed 20years ago. However the subject had not been studied in korea. Thus, our objectives is to examine the influence of osteoarthritis on bone density measurements.

Methods : The study group consisted of 120 women, aged over 40 years, who visited for health examination in Health Center of Poondang-Jesaeng general hospital from October 1998 to April 1999. Bone mineral density(BMD) of the lumar spine was measured, using dual energy X-ray absorptiometry(Lunar, Expert XL), and lateal lumbar spine radiograph was taken. Severity of osteoarthritis were scored on osteophytes, disk space narrowing and vertebral body sclerosis.

Results : Postmenopausal women had significantly lower BMD than premenopausal women(P<0.001). Age(r=-0.545,p<0.001), body mass index(r=0.264,p<0.01) and education(r=0.284, p<0.001) were significantly correlated with BMD, but smoking, exercise, radiogrphic OA variables not correlated. However, stepwise multiple regression analysis using osteoporosis related variables and OA variables is indicated that menopausal status, body mass index, age, osteophytes were significantly associated factor with BMD, and lumbar osteophytes explained 2.7% of variation in lumbar spine BMD.

Conclusion : We conclude that, among women, lumbar BMD is higher in those with osteophytosis of the lumbar spine. The effect is largely directed by osteophytes being included in the BMD measurement.

Background
: In order to provide basic data which are necessary for the standard reference of residency training program in family medicine, we analysed of family practice residency program in Korea(the core curriculum) which has 313 items - diseases and problems - proposed by the Korean Academy of Family Medicine.

Methods : Each item of the core curriculum of family practice residency program in Korea was sorted according to ICD-10. They were the most compared to common 100 diseases and clinical cases in family medicine department of a tertiary hospital in one year. The most common 100 diseases were listed according to ICD-10, also. But some items which were difficult to sort were excluded. Eighty eight types of diseases were sorted. Clinical data of a tertiary hospital included 9138 cases.

Results : Comparing to clinical cases of a tertiary hospital, the core curriculum includes 93.2% cases of family medicine department of a tertiary hospital. Among the 17 fields of the core curriculum, 12 fields were found in about 50% or more among cases of the clinic and 5 fields were in less than 50%.
Among 88 diseases, the core curriculum includes 78 diseases. 10 diseases were excluded. In the most common 100 diseases, 12 diseases were related to trauma and the core curriculum did not include them.

Conclusion : Generally the core curriculum included highly prevalent diseases, but did not include some diseases which is important. Revision to make up for the weak points in the current core curriculum may be necessary.
