BACKGROUND: Diet and weight concerns are commonplace and almost accepted features of life for girls during adolescence. Until recently, younger age groups haue largely been ignored, as these concerns were thought to be a product of pubertal development and sexual maturity. Girls under the age of fifteen therefore, have been assumed to be free of the pressures experienced by adult women. However, this belief is now hard to sustain. The object of the present study was to investigate the self-perception and body shape satisfaction in different weight categories of boys and girls aged 12-years old in Korea. METHODS: In May, 1995, one hundred and sixty seven boys and one hundred and twenty girls from two schools in Seoul completed assessments of body-esteem, self-esteem, body shape preference. The children's body weight and height were also measured. RESULTS: The heaviest children expressed the most discontent, having a low body-esteem, a desire for thinness. By the age of 12, girls boys already differ in their body shape satisfaction and differ in their body shape aspirations. There was a significant effect of weight category on the children's body esteem(boys(P =.005), girls(P=.0001). Children in both extreme categories, under-and over-weight, had lower body-esteem scores than those in other weight categories. However, it was the overweight children who had the lowest. reported body-esteem. Body esteem was highest among girls in the 'slightly underweight' category and highest among boys on the 'average weight' category. There was no effects of either weight category or gender on the childrens appraisal of self-esteem. A comparison of the points chosen on the silhouette scales to reflect current and preferred body shapes revealed clear gender differences. Of the girls, 63% placed their preferred body shape at a point thinner than their currently perceived shape, while only 15% chose a broader figure. In contrast,, 41% of the boys rated their preferred figure as broader than their current perception, and 37% as thinner than their current perception. CONCLUSIONS: This study has noted a relationship between body weight and self-perception in 12-year old children. The heaviest children expressed low body-esteem, a desire for thinness. This pattern was more characteristic of girls than boys. Even at this age, well before they have completed physical maturation, girls are aspiring to a body shape which is thinner than their average. This discontent experienced by the heaviest children on this sample was apparent in their lower body-esteem and the distance between their current and preferred body shapes. The girls preference was for thinness, while in the boys it was for a body shape which was broader than their current shape. From their responses, it would appear that the boys' desire was not for fatness, but for a more athletic and muscular build.

Myocardial bridging is defined as segmental engulfment of a major epicardial coronary artery by myocardial fibers, causing a systolic narrowing or milking effect of the coronary arterial segment. During systole, the intramuscular part of coronary artery is compressed by contraction of overbridging ventricular muscle, therefore blood flow distal to the lesion is impaired and angina pectoris or acute myocardial infarction may occur. We experienced a case of Non-Q myocardial infarction in a 42 years-old female patient with myocardial bridge at the proximal and middle part of left anterior descending coronary artery.

In a placebo-controlled trial, we have studied the vasodilator properties of bolus dose of nitroglycerin, isosorbide dinitrate and chlorpromazine in 38 patients during cardiopulmonary bypass with a constant pump flow. Mean arterial pressure and blood volume of the venous reservoir were recorded for 10 min after drug administration to detect changes in arteriolar resistance and venous capacitance, respectively. Nitroglycerin, 2.5 ug/kg, decreased arterial pressure, but the effect lasted for 3 minutes. Chlorpromazine, 0.1 mg/kg, decreased arterial pressure for 9 minutes. Isosorbide dinitrate, 20 ug/kg, had no significant change on arterial pressure. The venous capacitance-increasing effects of nitroglycerin and chlorpromazine were significant for 4 minutes after the bolus. Thereafter the effect of nitroglycerin began to decline, while that of chlorpromazine significantly continued. Isosorbide dinitrate had no significant change on venous reservoir level. The SVR reduction effects of nitroglycerin was significant for 3 minutes, chlorpromazine decreased SVR for over 10 minutes. In conclusion chlorpromazine effect on arterial pressure and venous capacitance was more potent and longer than nitroglycerin and isosorbide dinitrate. Nitroglycerin and chlorpromazine effect on preload and afterload were significant after bolus dose.

Overcrowding of emergency department is a serious and growing problem at St. Mary's Hospital. This has motivated the development of short-stay unit(SSU) as an alternative ward to routine hospital admission and ED discharge. In our hospital a SSU begun to admit patients in January 6, 1997. the SSU received 247 patients from the ED during the eight month interval(January 6, 1997 to August 31, 1997). To examine the utilization of the SSU in ED, we retrospectively analyzed 247 patients admired in SSU from the ED, and compared the average hours per patient with acute gastroenteritis spent in the ED doing the 2-month intervals before(July-August 1996) and after(July-August 1997) the establishment of the SSU. The following results were obtained; 1. The total patients consist of EM 92(37.2%), GS 48(19.4%), IM 24(9.7%), PS 21(8.5%), OS 20(8.1%), OBGY 14(5.7%) and others 28(11.3%). 2. The results of EM patients admitted in SSU from ED 1) Sex ratio of male to female was 1:1.1 and the mean age was 37.3+/-16 years. 2) In diagnosis, acute gastroenteritis was 29 cases(31.5%), multiple contusion 14 cases(15.2%), drug intoxication 12 cases(13%), limb laceration 6 cases(6.5%), tendon rupture offhand 6 cases(6.5%), and others 19 cases(20.6%). 3) Mean length of stay in ED was 9.18 hours. 4) Among 92 patients to the SSU, 79 patients(85.9%) were discharged, 11 patients(11.9%) formally admired to hospital and 2 patients(2.2%) transferred to otherhospital. The mean hospital stay time of the patients admitted to SSU was 2.6 days. 3. There was a significant reduction in the average stay time spent in the ED by treat-and-releasing patients with acute gastroenteritis after the establishment of the SSU(from 14.65+/-9.6 to 7.52+/-5.4 hr/patient, p<0.001). Conclusively, the establishment of the SSU can shorten the average stay time that treat-and-releasing patients spend in the ED, and reduce the number of admixed patients waiting in the ED.

There remains controversy regarding the appropriate surgical treatment for coarctation of the aorta because of relatively high rate of recoartation and high mortality in the cases associated with complex anomalies. We evaluated 31 consecutive patients who underwent surgical repair of coarctation of the aorta from May 1992 through June 1996. Nineteen patients(61.3%) were neonates and 26(83.9%) were under three months. Nine patients did not have major associated anomalies(Group I), 15 patients had ventricular septal defect(Group II), and 7 patients had major complex anomalies(Group III). 35.5% of the patients had arch hypoplasia. Surgical procedures performed were as follows: extended end-to-end anastomosis in 17 patients, combined resection-flap procedure in 7 patients, and subclavian flap aortoplasty in 7 patients. Residual coarctation occurred in 7(25%) of 28 patients; 2 after subclavian flap aortoplasty(2/6, 33.3%), none after combined resection-flap procedure(0/7, 0%)), and 5 after extended end-to-end anastomosis(5/15, 33.3%). Higher incidence of residual coarctation was noticed in the group with arch hypoplasia. The incidence of postoperative coarctation at a mean follow-up of 20.5 months in survivals was 12.0%(3/25); 2 cases after subclavian flap aortoplasty(2/6, 33.3%), none after combined resection-flap procedure(0/7, 0%), and one after end-to-end anastomosis(1/12, 8.3%). The mortality rate related to coarctation repair was 9.7%(3 patients, all in Group III). This study revealed that isolated coarctation of aorta and coarctation with ventricular septal defect(groups I and II) can be repaired with low mortality, but repair of coarctation with complex anomaly had a high operative mortality. Also the patients with arch hypoplasia had higher incidence of post-operative residual coarctation.

Patellectomized patients may have less satisfactory clinical outcomes following total knee arthroplasty (TKA) due to a decreased extensor mechanism efficiency and potential instability. Furthermore, the existing literature does not provide concrete guidance on the expected results of TKA or the type of implant that should be used in patellectomized patients. We present a case of a patient with an ankylosing knee who had undergone patellectomy due to gunshot injury 45 years ago and was treated with primary TKA using a posterior stabilized prosthesis at our institution. TKA using this prosthesis in the ankylosed knee with a previous history of patellectomy yielded good results in terms of postoperative clinical scores, range of motion and joint stability.

PURPOSE: The purpose of this study is to compare and analyze the precision of optical and electromagnetic navigation systems in total knee arthroplasty (TKA). MATERIALS AND METHODS: We retrospectively reviewed 60 patients who underwent TKA using an optical navigation system and 60 patients who underwent TKA using an electromagnetic navigation system from June 2010 to March 2012. The mechanical axis that was measured on preoperative radiographs and by the intraoperative navigation systems were compared between the groups. The postoperative positions of the femoral and tibial components in the sagittal and coronal plane were assessed. RESULTS: The difference of the mechanical axis measured on the preoperative radiograph and by the intraoperative navigation systems was 0.6 degrees more varus in the electromagnetic navigation system group than in the optical navigation system group, but showed no statistically significant difference between the two groups (p>0.05). The positions of the femoral and tibial components in the sagittal and coronal planes on the postoperative radiographs also showed no statistically significant difference between the two groups (p>0.05). CONCLUSIONS: In TKA, both optical and electromagnetic navigation systems showed high accuracy and reproducibility, and the measurements from the postoperative radiographs showed no significant difference between the two groups.

BACKGROUND: This study was done to determine whether the Osteoporosis Self-assessment Tool (OST) can predict central bone mineral density in Korean men above 50 years, as defined by dual energy X-ray absorptionmetry (DXA). METHODS: We applied the OST index to Korean men aged over 50 in Health Promotion Center of Konkuk University Hospital from September 2005 to September 2008. The calculated OST risk index was based on weight and age, truncated to an integer. RESULTS: The study population was 276 men. The mean age, height and weight of the men were 59.7 +/- 6.69 years, 167.6 +/- 6.14 cm and 67.5 +/- 8.93 kg respectively. By DXA, 4.7% of the men had a T score of -2.5 or less, and 46.4% had a T score of -2 or less at the spine, total hip, or femoral neck. The OST index ranged from -4 to 7. Using a cutoff score of 0, we predicted osteoporosis with a sensitivity of 85% and a specificity of 62%. The receiver operating characteristic curve showed an area under the curve of 0.77. When the subjects were analyzed by age and smoking status, the predictive value of the OST was maintained. CONCLUSION: The OST is a simple and useful method to predict osteoporosis in Korean men.

Splenic infarction caused by malaria is a rare complication and this is mostly caused by plasmodium falciparum. We report here on a 38 year-old female patient who developed symptomatic splenic infarction that was caused by vivax malaria. She presented with fever and left upper quadrant pain. Computed tomography showed multiple low density areas in the spleen, and the peripheral blood smear revealed plasmodium vivax infestation. We examined for other causes of splenic infarction, but all were negative. This is just the second report of symptomatic splenic infarction that was caused by vivax malaria only. Unlike the previous case, the levels of D-dimer and fibrinogen degradation factor were elevated. This may be related with the hypercoagulable state caused by malaria. Treatment was conservative and the further course was uneventful.
