BACKGROUND: The prevention of preterm deliveries still remains a major problem in ob-stetrics. The cause of preterm labor is poorly understood. Our purpose was to determine the risk factors for preterm labor associated with specific clinical and environmental factors. METHODS: Using a case-control design, 54 women with preterm labor and 134 controls with term labor, who were admitted to the department of Obstetrics and Gynecology, Dan- kook University Hospital from January, 1996 to August, 1996. The study groups were inte- rviewed and their medical records were reviewed. RESULTS: 1. There were no significant differences of maternal age, maternal weight at 20 weeks of gestation and maternal weight gain at the time of delivery. 2. There were no significant differences between housewives and working women. But the physical workload of the preterm labor group was significantly higher than the control group ( 16.0% vs. 4.0% ). 3. There were no significant differences in the smoking habit of mother or her husba- nd. The passive smoking of the preterm labor group was significantly higher than the con- trol group ( 43.8% vs. 26.8% ). 4. In vaginal bleeding at pregnancy, the preterm labor group was significantly higher than the control group ( 15.7% vs. 2.3% ). Especially, the third trimester vaginal bleeding of the preterm labor group was significantly higher than the control group. 5. There were no significant differences in the number of previous fullterm deliveries, previous abortions, and living children between two groups. The experience of the previous preterm deliveries of the preterm group was significantly higher than the control group ( 11. 5% vs. 0.8% ). 6. There were no significant differences of medications, consumption of alcohol, coffee, tea, green-tea, cola and nutritional beverages, the experiences of coitus, defecation numbers and accidents during pregnancy between two groups. 7. There were no significant differences in the plasma concentrations of hemoglobin, hematocrit, white blood cells, and in the blood pressure, and the body temperature between two groups. CONCLUSION: The risk factors of preterm labor were severe physical workload, vaginal bleeding at pregnancy, especially, the third trimester vaginal bleeding, and the experience of previous preterm deliveries.

Secondary osteoarthritis of hip joints is a common disease and is frequently followed by chronic sublexation and dislocation. Twenty four case of the secondary osteoarthritis associated with chronic subluxation and dislocation of the hip joints were evaluated with plain radiography and computed tomography. We retrospectively analyzed 1) the ossification and calcification of the acetabular labrum, 2) the thickeness of the quadrilateral plate of the ilium, and 3) anteroposterior diameter of the acetabulum. The changes of the hip joints in subluxation (n=14) revealed ossification of the acetabular labrum in 12 cases (86%), thickening of the quadrilateral plate of the ilium in 11 cases (78%) but anteroposterior diameter of the acetabulum was not changed. The changes of the hip joints in dislocation (n=10) revealed no evidence of the ossification of the acetabular labrum, thickening of the quadrilateral plate of the ilium in 10 cases (100%) and decreased anteroposterior diameter of the acetabulum. We conclude that CT findings of subluxation and dislocation of the hip joints can be helpful in the evaluation of the secondary osteoarthritis of the hip joints.

Fine needle aspiration cytology of the salivary lesions was performed on 221 patients at Soonchunhyang University Hospital for 10 years. Of 221 aspirates, 6 aspirates(2.7%) were inadequate, 116 cases(52.5%) were non-neoplastic lesions, 76(34.4%) cases were benign neoplasms and 23 cases(10.4%) were malignant neoplasms. The cytologic diagnoses could be correlated with histologic findings in 58 cases. FNAC correctly discriminated between neoplastic and nonneoplastic lesions in fifty-seven lesions and failed in a case, and overall accuracy, sensitivity, and specificity were 98.3%, 98.0%, and 100.0%. FNAC correctly discriminated malignant neoplasms from benign neoplastic/non- neoplastic lesions in fifty-three cases and failed in five cases, and overall accuracy, sensitivity, and specificity were 91.3%, 72.7%, and 95.7%. Among three false negative cases, two mucoepidermoid carcinomas were misdiagnosed as mucocele and benign neoplasm, and an acinic cell carcinoma were misdiagnosed as Warthin's tumor. Two false positive cases were a Warthin's tumor misdiagnosed as squamous cell carcinoma and a pleomorphic adenoma misinterpretated as suggestive of malignancy. In conclusion, diagnostic accuracy of FNAC of salivary lesions is high, and the possibilities of low grade mucoepidermoid carcinoma and acinic cell carcinoma should be considered on hypocellular smears with mucoid or fluidy background.
