Background
: This study was performed to examine the clinical usefulness of abdominal ultrasonography in health screen.

Methods : Medical records and health screen records of 405 cases without chief complaint which were visited at general health screening center of Dongsan medical certer during 4 month - period from may, 1993 to august, 1993 were analyzed.

Results : We experienced 77% of normal ultrasonographic finding and 33% of abnormal ultrasonographic finding in 405 cases examined. We reviewed the results of the most common abnormal ultrasonographic finding in order of each organs, which were detected fatty liver in 17% : gallstone in 4% : renal cyst in 1.7% : splenomegaly in 0.7%. The classification of abnormal ultrasonographic finding were fatty liver, chronic hepatocellular disease, gall stone, clonorchiasis, liver cyst and renal cyst in order of decreasing frequency.
Sensitivity of ultrasound study in clonorchiasis was 43% and positive predictive value was 43% but specificity was 98%.

Conclusion : These results suggest it is well worth employing sonograph for health screening purposes especially for early detecrion of fatty liver, chronic hepatocellular disease, clonorchiasis, gallbladder stone, renal cyst, renal stone and splenomegaly. And analysis aspect expense-effect are required.

Background
: It is a recent trend that average life span prolonged according to the socioeconomic and scientific advance, therfore elderly patients are steadily increasing. The interest toward geriatrics raise earlier. Never the less, present epidemiologic study to geriatric patients is rare, in our country. This study purpoted to make basic epidemiologic data of geriatric in-patients.

Methods : The subjects were 65 years old patients and over that visited to small and medium hospital of Andong city from June 1991 to March 1992. Among them new in-patients of 65 years old and over hospitalized at March, June, October, December were selected and their charts were reviewed.

Results : Male and female ratio of 216 geriatric inpatients was 1:1.3 and average age was 72.5 years. The average numbers of diagnosis were 2.6 and the most common disease was hypertension, others were COPD, fractures, gastritis, malignant tumors, degenerative arthritis as in order and the average duration of hospitalization was 9.1days in geriatric in-patients. The average numbers of class of prescribed drugs in geriatric inpatients were 5.6 and the significant difference was not noticed in sex and age. The most common prescribed drug was antibiotics, The average of total cholesterol was 162.9mg/dl and dangerous group was 7.3%, borderline group was 11.8% by NCP guideline. The ratios of smokers and alcoholics were 50.0%, 34.4% respectively.

Conclusion : This study was concerned about common diseases, prescribed drugs and health risk factors in geriatric in-patients. But this study was limited to small area and one community. Therefore, this result can't represent the result of the total geriatric population. As this reason, I wish to more & more great epidemiologic study about geriatric inpatients will being done in the future.

Background
: Life event is universal one which everybody experiences. Headache is one of the most common symptoms in primary care. However, there have been a few studies of the relationships between life events and headache.

Methods : Fifty-nine new patients were selected from the patients who complained headache and visited our family medicine clinic for periodic health examination from Mar. 1 to July 31, 1991. Control group was also selected from the population who did not complained headache and visited the clinic for periodic health examination from Sep. 1 to Sep. 30, 1991.

Results : The mean of total stress score in the study group are 935±657 and 489±333(P<0.0001) in the control group. There was a significant difference in the mean scores of negative stress events between the study and control groups(P<0.05). But there was no difference in the mean scores of positive stress events between the study and control groups. There were significant differences in marital problem, familial conflicts, health problem between the study and control groups.

Conclusion : There was a significant relationship between headache and life events. Also headache is associated with negative stressor, marital problem, familial conflicts, health problem.
