The distribution and type of the whorl on headhair and pubic hair were observed for Korean male youths at physical examination of freshman students of our university. I) In the observation on the whorl on headhair for 1293 male youths, following results were obtained. a) i) The single whorl was found 93.89% of the case. ii) The double whorl was found 5.49% of the case. iii) The triple whorl was found 0. 62% of the case. b) The most of the whorl situated on median sagittal line of the head. It occurs more often on the right side (30.4%.) than on the left (15.8%). c) The single whorl in the clockwise direction predominates over the counterclockwise. d) It is found in 52% of all cases that position double whorls had showed the one on the right side and the other on the left. And the double whorl showed the combination of spiral opposing directions in more than 80% II) In the observation on pubic hair of 6131 Korean male youths, following results were obtained. a) Below 18 years old: i) The horizontal type was found in 78.6% ii) The sagittal type was found in 6.3% iii) The acuminate type was found in 11.0%. iv) The disperse type was found in 3.4%. b)Over 19 years old: i) The horizontal type was found in 71. 6% ii) The sagittal type was found in 8. 5% iii) The acuminate type was found in 14.7% iv) The disperse type was found in 4. 9% c) The 0,75% of all cases can not be found pubic hair below 19 years old, the 0, 25% of the case can not be found pubic hair between 20-24 years old and 0.34% of total case (6131) whose age are ranging 17 years old to 24 years old were found bald pubic hair.

We performed twenty three cementless total hip arthroplasties(THA) on seventeen patients, all of whom were diagnosed with steroid-induced avascular necrosis of the hip (AVN). The average age of the patients was 41years, mean follow-up period was 41months (24-74months). The final average Harris hip score was 94 and overall results were excellent. On radiographic evaluation, 17 femoral components met the criteria for bone ingrowth(spot weld) but it was somewhat delayed. There was no evidence of loosening of the femoral and acetabular components. The results of this study suggest that long term steriod treatment does not prevent bone ingrowth. Cementless total hip arthroplasty appears to be a reasonable therapeutic option for steroid-induced avascular necrosis of the hip.

The extent of excision and necessity of hepatectomy in type IVa choledochal cyst has not been clarified. We performed left lobectomy of the liver for complete excision of the cyst in a thirty-year-old male patient with type IVa choledochal cyst. Postoperative recovery was untroubled and outcome was satisfactory. Complete excision of the cyst including hepatectomy is an acceptable operative management for patients with type IVa choledochal cyst. This procedure can eliminate the possibility of subsequent cancer arising from remaining cyst.

Avariety of symptoms can occur following traumatic brain injury(TBI) or other types of acquired brain injury. These symptoms can include problems with short-term memory, attention, planning, problem solving, impulsivity, disinhibition, poor motivation, and other behavioral and cognitive deficit. These symptoms may respond to certain drugs, such as dopaminergic agents. Amantadine may protect patients from secondary neuronal damage after brain injury as a effects of NMDA receptor antagonists and may improve functioning of brain-injured patients as a dopaminergic agonist. Clinically, based on current evidence, amantadine may provide a potentially effective, safe, and inexpensive option for treating the cognitive, mood and behavioral disorders of individuals with brain injury. The rationales for using amantadine are discussed, and pertinent literatures are reviewed.

The head patient with musculoskeletal trauma is a challenge to the orthopedic surgeon and its incidence is increasing markedly with the development of modern culture and a high velocity motor vehicle. So, for the purpose of studying the difference between lower extremity fracture concomitant with head injury and only lower extremity fractured patients, we studied the radiologic bone union time, serologic test and heterotopic ossification. For the control group we analysed each 10 patients of only femur and tibia fractures. The following clinical results were obtained by analysis of 46 patients of lower extremity fracture concomitant with head injury, experienced in the Department of Orthopedic Surgery, Yonsei University College of Medicine in past 5 years from Jan. 1980 to Dec. 1984. 1. The mean age was 24.5 yrs old (2~6 yrs old) and the prevalent age was 1st and 3rd decade, and the sex ratio between males and females was 2.8: l. 2. The most common mode of injury was auto-pedestrian injury (84.8%) and the other was falling down injury(15.2%) . 3. The common brain injuries were cetebral contusion with skull fracture (37.0%) and cerebral contusion only(34.8%) . Among 26 patients whos mental states were not alert, 23 patients recovered mental states completely. 4. Serum Calcium, Phosphate, and Alkaline Phosphatase level were no difference between the head injury with lower extremity fractured patients and only lower extremity fractured patients. 5. There were no evidence of early bony union in the patients with head injury. 6. The formation of callus were abundant in the patients of lower extremity fracture with head injury rather than the only lower extremity fractured patients. 7. The incidence of heterotopic ossification was 10.9% and all patients with heterotopic ossification were treated with physiotherapy and all patients recovered fully. 8. The incidence of complication was 17.3% and there was no fat embolic patients. In conclusion, there was no evidence of early bony union, but the callus formation was abundant in the patients of lower extremity fracture concomitant with head injury.

OBJECTIVE: Estrogen is a major regulator/modulator of bone metabolism, and bone loss in estrogen deficiency is associated with increased bone turnover, But the mechanism for estrogen action on bone metabolism is still unknown. Recent studies have suggested that the increase in bone loss induced by estrogen deficiency is mediated by increased paracrine production of bone resorbing cytokines. Among cytokines, 1nterleukin-6(IL-6) is released from osteoblasts in estrogen deficiency and increases bone resorption by stimulation of osteoclastic activities and recruitment. Thus we performed this study to evaluate the effect of ovariectomies on bone mineral density and IL-6 in cultured monocytes of peripheral blood and bone marrow. METHODS: The experimental animals were 13 female Sprague-Dawley rats that were 8 weeks of age and weighed an average of 188.5 gram at the beginning of the study. Bilateral ovariectomies were performed in all rats from a ventral approach. Bone mineral density(BMD) of the total body, spine and level of IL-6 of cultured monocytes of peripheral blood and bone marrow were measured before and 8 weeks after ovariectomy. RESULTS: 1) BMD of total body and spine were lower after ovariectomy(0.257+/-0.069g/cm2, 0,208+/-0.005g/cm2) than before ovariectomy (0.276+/-0.005g/cm2, 0.229+/-0.011g/cm2), respectively (P<0.01). 2) Although IL-6 level of cultured monocytes in peripheral blood tended to be higher after ovariectomy than before ovariectomy, this difference was not statistically significant (P>0.05). 3) IL-6 level of cultured monocytes in bone marrow was higher after ovariectomy(82.78+/-4.99pg/ml) than before ovariectomy(48.85+/-2.42pg/ml)(P<0.05). CONCLUSION: It is possible that increased production of IL-6 in estrogen deficiency induced by ovariectomy occurs in the local environment of bone or bone marrow rather than in the pheripheral blood and stimulates bone resorption.

Eighty primary Harris-Galante Porus (HGP) total hip replacements were performed at Severance Hospital from January 1986 to January 1989. A minimum of 18 months follow-up was available for 80 hips in 72 patients, whose mean age was fifty two years. The most common presenting diagnosis was avascular necrosis (47.5%) followed by fused hips (10%), tuberculosis (10%), rheumatoid arthritis (7.5%). Complications included three calcar cracks and two immediate dislocations and 6 cases of mild myositis ossificans. There were no infections and no revisions. The mean Harris hip score was 93 points (range, 74–100 points) at two years. The thigh pain was in nine patients (11 per cent) at one year and in three patients (3 per cent) at two years postoperatively. Radiographic analysis revealed that, a progressive radiodense femoral line developed in 21 hips (26 per cent); a progressive acetabular line in 3 hips (4 per cent); and decreased proximal femoral density in 28 hips (35 per cent). There were no position change of the acetabula and femoral compent. We conclude that the early overall clinical results of HGP total hip replacements are encouraging, at average 30 months. The prognostic significance of the radiographic changes such ar radiodense lines, the changes of the proximal femur and cortical thickening, have to be determined with longer follow-up. Long term follow-up of uncemented HGP total hip replacement is necessary to evaluate the efficacy of such implants.

A cross-sectional survey was conducted to determine the prevalence rate of scoliosis in elementary, middle and high school boys in May 1988. The study population included 1,393 male students in Pusan ; 463 students of 4th grade in two elementary schools, 543 students of 1st grade in one middle school and 387 students of 1st grade in one high school. The students of elementary school were screened with inspection by two physicians at the same time and the students of middle and high schools were screened with both inspection by the same physicians and 70mm chest X-ray. Positive students in any one of the two screening tests were measured for height and body weight and asked for the shoulder side on which he carries the school bag. The angle of curvature on X-ray film was measured by Cobb's method. The number of positive students in any one of the two tests were 15(3.2%) in elementary schools, 174(32.0%) in middle school and 92(23.8%) in high school. However, positive rates in both tests were only 2.2% for the middle school students and 2.6% for the high school students and among these students 1.1% out of total middle school students and 2.3% of high school students had a curvature equal to or greater than 5 degrees of Cobb's angle on 70mm chest X-ray film. There was a statistically significant association between the direction of spinal curve and the shoulder side on which one carries school bag among positive students in both screening tests (p<0.05). Mean height and body weight of 281 positive students in any one of two screening tests were compared with the Korean standard for the same age. Mean weight of elementary school students was nearly the same as the standard weight but the height was slightly shorter than the standard. However, both mean height and weight of the middle school students were lower than the standard while those of the high school students were higher. The prevalence rate of scoliosis for the 2nd 3rd grades of high school is presumed to be higher than that of the 1st grade of high school and the rate for girls will be even higher than the rate for boys of the same age. Thus, scoliosis seems to be an important school health problem. To prevent scoliosis, it is recommended to reduce the weight of school bag, educate the students to keep a right posture and exercise periodically.
