BACKGROUND: The purpose of this study was to identify risk factors for low back pain in order to provide basic information for intervention programs to prevent low back pain in civil airline flight attendants. METHODS: Cross sectional observation was used by using systematic randomized sampling method. Among 1,764 study population, 398 people were selected. For statistical analysis, 210 completed questionnaires were used. Data was analyzed using SPSS 11.0 for t-test, chi square and regression. RESULTS: 1. Positive low back pain rate was 58.7% in the whole study group. In the highest positive group age ranged between 25 to 29 years, and career duration between 37 to 60 months. 2. According to job position, the risk of low back pain was the highest in economy class senior, cabin sales charge, and economy class junior group. On the contrary, cabin manager was the lowest risk group. 3. According to the average score of job stress, low job control and low supervisory support were each associated with higher positive rate of low back pain. 4. Wide degree of bending, more frequent waist movement and heavy lifting showed high positive rate of low back pain. CONCLUSION: Low back pain prevention program should be developed on the basis of the confirmed risk factors. These data will be helpful to provide prevention strategy and to promote intervention program for low back pain in airline flight attendants.

Abnormalities in the number and function of platelets may contribute to thromboembolic complications in patients with essential thrombocythemia(ET). Physicians often use hydroxyurea which reduces the platelet count for the initial treatment of ET. A 74-year-old man with ET was presented with headache, dysarthria, and right hemiparesis 10 months after discontinuation of hydroxyurea. Initial platelet count was 450x103/microliter and we gave him heparin. However, his platelet count rised upto 1,019x103/microliter within 4 days. He was on hydroxyurea 1.5 g/day and his symptoms improved with decrease of platelet count. We report a case of left MCA(middle cerebral artery) multifocal infarction in ET after discontinuation of hydroxyurea.

Fibro-osseous pseudotumor is an extremely rare benign lesion which is fast-growing and painful. It is often misdiagnosed as a malignancy, but it is a noninvasive entity and can be cured by simple resection. We report a case of fibro-osseous pseudotumor of the distal phalanx of great toe in 20-year-old female patient who present with painful mass.

The purpose of this study was to investigate the related factors to child overweight through investigation of children aged 6-12. Data on physical examinations, family history and dietary habits were obtained. Children were classified into normal(98 persons) and overweight(118 persons) group using the combination of height for age, weight for age and weight for height standard by the World Health Organization. Children's height, weight and BMI exhibited a significant difference between groups except children aged 8 for height. Unbalanced diet was a risk factors for overweight(Odd ratio : 1.765, 95% CI : 1.022~3.048). Number of brothers showed negative significance especially in two brothers compared to that of one(Odd ratio : 0.456, 95% CI : 0.209~0.995). But Birth weight, feeding practice, overeating, taking nutrition pills, sleeping time, mother's education level and employmental status didn't have any difference. We found out there were different risk factors between obese and overweight group. They should be divided into different groups in studying risk factors. And we should pay much attention to overweight children in order to prevent improving to obesity.

BACKGROUND: Trisomy 16 in mice is considered to be an animal model for Down's syndrome in human. We studied the morphologic characteristics of the heart and the edema, and their significance to the teratogenesis in this animal model. METHODS: A total of 30 dams were sacrificed to bear 125 (61.9%) normal fetuses 35 (17.3%) abnormal fetuses and 42 (20.8%) resorptions. Cytogenetic study and morphological examination were performed using microdissection agar-mount sectioning histologic examination and scanning electron microscope. RESULTS: The crown-rump length was significantly shorter in abnormal (trisomic fetuses) than the normal (eusomic) fetuses. Trisomic fetuses showed massive edema at the back from the vertex to the lumbar area. Four-chamber view section of the agar-mount and histologic section showed a common atrioventricular valve bridging the left and the right atrioventricular junction. Scanning electron microscopic examination on atrioventricular valves showed three types of atrioventricular valves:five cases with common atrioventricular orifice, three cases with partitioned atrioventricular orifice and two cases with atresia of the right atrioventricular orifice. CONCLUSION: This study confirmed the presence of massive edema and cardiac anomalies in the mouse with trisomy 16. But there was morphologic diversity of cardiac anomaly in this model.

Induced refractive errors or anisometropia are known to cause reduction in stereoacuity. We compared the reduction of stereoacuities in anisometropia between far and near stereotests to determine the value of these tests as a screening tool of anisometropia. The far stereoacuity of 3m distance was tested with a red-green RDS developed with a color computer, and the near stereoacuity with TNO test in 10 normal adult volunteers. The effect of anisometropia. on the stereoacuity was tested by placing spherical lenses in 0.5 D steps bfore one eye(-2.0 D ~ +2.0 D). Stereoacuities tested at far showed a more rapid decrease than those at near as the power of the lenses was increased. The plus lenses showed more deteriorating effect on the stereoacuity than the minus lenses. And all subjects showed more than 620 arc seconds of stereoacuities with more diopter than +1.5D spherical lens. The far stereotest seems to be a more sensitive screening tool of anisometropia than the near stereotest especially in the mild degree(less than 2.0 D) of anisometropia.
