Evidence in human studies of the association of long term habitual exercise with bone mineral content (BMC) and bone mineral density (BMD) mostly come from studies done on athletes. The highest BMC and BMD values in young adults have been found in strength and power-training athletes, while endurance activities such as long distance running and swimming seem to be less effective in obtaining peak bone mineral density. To compare the differences in BMD among ballet, Korean traditional dancing and athletics, we examined the BMD of 10 ballerinas, 10 Korean traditional dancers, 12 athletes and 12 volunteers as the control group. All participants were female. The average age were 20.6 years for the ballerinas, 21.2 for the Korean traditional dancers, 20.4 for the athletes and 21.3 for the control group. Average weights were 50.6 kg for the ballerina, 53.7 kg for the Korean traditional dancer, 59.2 kg for the athletes and 53.8 kg for the control group. Average heights were 162.0 cm for the ballerinas, 160.4 cm for the Korean traditional dancers, 162.3 cm for the athletes and 160.5 cm for the control group. There were no significant differences in the BMD values of the proximal femur and the lumbar spine between ballerinas and control group and between Korean traditional dancers and control group (p>0.05). There was, however, a significant increase of BMD in the proximal femur and lumbar spine of the athletes when compared with the control group (p<0.05) After adjusting for difference in body mass index (BMI) we recompared the BMD of ballerinas, Korean traditional dancer and athletes with BMD of control group and found significant higher lumbar spine BMD values in ballerinas, Korean traditional dancers and athletes. In athletes higher BMD levels were also obtained in the proximal femur including the neck, greater trochanter and Wards triangle regions (p<0.05). There was no significant increase of proximal femur BMD levels for Korean traditional dancers (p>0.05). Differences of BMD values between the ballerinas and control group was statistically significant only in femoral neck (p<0.05).

Fractures of the body of the talus are extremely rare, constituting only about 0.1 percent of all fractures (Coltart 1952). Consequently, the prognostic problems have so far been elucidated only on the basis of few reports in the literature. The authors experienced an unusual type of the shearing fracture of the talar body with total disocation that the talar body was lying upside down in the ankle joint. Satisfactory results were obtained after follow up period of 20 months and some are reporting this case with bibliographic reviews.

BACKGROUND: Several methods have been developed to measure skin thickness, including the use of the radiography, micrometer screw gauge, Harpenden's caliper, and ultrasound, but there are no reports to measure skin thickness using computed tomography. OBJECTIVE: We measured skin thickness on the CT films retrospectively. This study was to investigaste variations of skin thickness by age, gender, and different sites. METHODS: Skin thickness was measured on the CT films of 562 patients, including 357 males and 205 females who had undergone brain, chest, and abdominal CT in our hospital. Patients with endocrinologic, malignant, or collagen disease and those on antimetabolite or steroid therapy were excluded. Comparisons of histometric and computed tomographic methods weremade in 5 skin tumors and 1 localized lipodystrophy. Results: 1. The measurements of the skin thickness(mean) in examined sites varied from 0.84 to 3.07 milimeters : the posterior part at the level of the chest(aortic arch level) was the thickest and the anterior part at the level of the forehead(aortic arch level) was the thickest and the anterior part at the level of the forehead(frontal sinus level) was the thinnest. 2. Skin thickness in males wal generally thicker than in females : the anterior and lateral part at the level of the forehead(P<0.0001), the posterior part at the level of the bladder(P<0.2) were thicker in males than in females. 3. In each gender, the thickness of the skin increased with age of 40 or 60, and then decreased with age at every level. 4. Skin on posterior parts of the body was thicker than on other parts. 5. Unlike other levels, skin was thicker on the lateral parts than on the anterior parts at the levels of the forehead and bladder. 6. The measured skin thickness in about 7% greater in formalin fixed tissues than on CT films. CONCLUSION; Computed tomographic measurement of the skin thickness in a reliable method in the aquisition of normal values and their individual variations during cutaneous aging. Moreover, this method is useful in evaluating skin tumors and monitoring the response to therapy of inflammatory conditions.

Angiogenesis is an essential requirement for development, progression, and metastasis of malignant tumors. Vascular endothelial growth factor (VEGF) is one of the important angiogenic factors. Recently the role of angiogenesis has been known in premalignant lesions. This study was performed to determine whether the angiogenesis and VEGF expression were increased in association with histological grade of cervical intraepithelial neoplasia (CIN) and to see the relationship between the angiogenesis and VEGF. Immunostainings for factor VIII and VEGF were performed on 52 cases of cervical neoplasia (12 cases of CIN I, 11 cases of CIN II, 15 cases of CIN III, 7 cases of microinvasive squamous cell carcinoma, and 7 cases of invasive carcinoma) and 5 cases of normal cervix. The results showed a significant increase of microvessel count from normal cervix through CIN grades to invasive squamous cell cacinoma. VEGF expression was increased in proportion to the CIN grades. There was no significant correlation between microvessel count and VEGF expression. In conclusion, the tumor angiogenesis is an early event in tumorigenesis of uterine cervix. In addition, no significant relationship between the microvessel count and VEGF expression in CIN suggests the possibility of other growth factors affecting mainly angiogenesis of premalignant lesion of uterine cervix.

BACKGROUND: Acute abdominal pain is one of the most common problems in the family practice but the differential diagnosis of acute abdominal pain is difficult in first encounter. When family physicians are encountered with patients with acute abdominal pain in the ambulatory care settings, t,hey have to make a decision for management of acute abdominal pain such as admission, referral, discharge or follow-up without any definite diagnosis. If it is possible to predict the course or prognosis of acute abdominal pain by using certain data about patients, it will be helpful to make a decision for the management of acute abdominal pain. So we tested the hypothesis that acute abdominal pain with intermittent pain nature and normal simple abdomen X-ray finding is not serious and shows favorable outcome. METHODS: 126 patients with acute abdorninal pain were enrolled from Feb. to Aug. in 1995 at the emergency department of Kyungju hospital, Dongkuk University. 116 patients showed normal simple abdomen X ray finding and among them 94 patients were discharged and 21 patients were admitted. 92 patients were contacted in 1 week by phone call and they reported the outcome of their acute abdominal pain. RESULTS: Among 92 study populations, 44 patients were male and 48 patients were female. 72 patients complained intermittent abdominal pain and 21 patients complained continous abdominal pain. Frequencies of tentative diagnosis at emergency department were 45 acute gastroenteritis, 26 unknown, 14 functional gastointestinal disorders, 4 acute gastritis, 2 pelvic inflammatory diseases, and 1 ureter stone. Outcomes of patients with intermittent abdominal pain were more favorable than those with continous abdominal pain. CONCLUSIONS: If the patients with acute abdominal pain have intermittent pain nature and normal simple abdomen x ray finding, they will show favorable outcome and can be managed at ambulatory care settings.
