Background: Sternal infection or dehiscence after cardiac surgery through median sternotomy is rare. If suitable treatment is not performed for the complication, however, the mortality is high. For 12 patients with sternal dehiscence or infection, we performed wide excision of the infected and necrotic tissue and covered with muscle flap(s) to obliterate the mediastinal dead space. Material and method: Sternal infection or dehiscence occurred in 13 of patients who underwent cardiac surgery One patient, who died of cerebral infarction before the sternal complication was treated, was excluded in this study. The sternal wound complication occurred in 6 of patients with valve replacement and 6 of patients with coronary bypass surgery, respectively. Since 1991, 9 patients underwent definite surgical debridement and muscle transposition as soon as fever was controlled with closed irrigation and drainage. The necrotic tissue and bone was widely excised and the sternal dead space was eradicated with the single flap or the combined flaps of right pectoralis flap(turnover flap), left pectoralis flap(turnover flap or rotation-advancement flap), and right rectus muscle flap. Result : There was no mortality in 12 patients with coverage of muscle flap(s) for sternal infection or dehiscence The mean interval between the diagnosis of sternal complication and the myoplasty was 6.6$\pm$3.9 days. In 4 patients, one pectoralis muscle flap was used, and in 8 patients both pectoralis muscle flaps were used. For each 1 patient and 2 patients in each group, right rectus muscle flap was added. For the last 3 patients, a single pectoralis flap was used to eradicate the mediastinal dead space and the longer placement of the mediastinal drain catheter was needed. One patient, who had suffered from necrosis of left pectoralis flap(rotation-advancement flap) with subsequent chest wall abscess after coverage of both pectoralis flaps, was managed with reoperation using right rectum flap. Conclusion : Sternal dehiscence or infection after cardiac operation can be readily managed with wide excision of necrotic infected tissue(including bone) and muscle flap coverage after short-term irrigation of sternal wound. The sternal(mediastinal) dead space may be completely eradicated with right pectoralis major muscle flap alone.

Purpose: This study was designed to evaluate the effects on bone mineral density (BMD) and related factors according to the distance from the radiation field at different sites. This study was conducted on patients with uterine cervical cancer who received pelvic radiotherapy. Materials and Methods: We selected 96 patients with cervical cancer who underwent determination of BMD from November 2002 to December 2006 after pelvic radiotherapy at Kosin University Gospel Hospital. The T-score and Z-score for the first lumbar spine (L1), fourth lumbar spine (L4) and femur neck (F) were analyzed to determine the difference in BMD among the sites by the use of ANOVA and the post-hoc test. The study subjects were evaluated for age, body weight, body mass index (BMI), post-radiotherapy follow-up duration, intracavitary radiotherapy (ICR) and hormonal replacement therapy (HRT). Association between the characteristics of the study subjects and T-score for each site was evaluated by the use of Pearson's correlation and multiple regression analysis. Results: The average T-score for all ages was -1.94 for the L1, -0.42 for the L4 and -0.53 for the F. The average Z-score for all ages was -1.11 for the L1, -0.40 for the L4 and -0.48 for the F. The T-score and Z-score for the L4 and F were significantly different from the scores for the L1 (p<0.05). There was no significant difference between the L4 and F. Results for patients younger than 60 years were the same as for all ages. Age and ICR were negatively correlated and body weight and HRT were positively correlated with the T-score for all sites (p<0.05). BMI was positively correlated with the T-score for the L4 and F (p<0.05). Based on the use of multiple regression analysis, age was negatively associated with the T-score for the L1 and F and was positively correlated for the L4 (p<0.05). Body weight was positively associated with the T-score for all sites (p<0.05). ICR was negatively associated with the T-score for the L1 (p<0.05). HRT was positively associated with the T-score for the L4 and F (p<0.05). Conclusion: The T-score and Z-score for the L4 and F were significantly higher than the scores for the L1, a finding in contrast to some previous studies on normal women. It was thought that radiation could partly influence BMD because of a higher T-score and Z-score for sites around the radiotherapy field. We suggest that a further long-term study is necessary to determine the clinical significance of these findings, which will influence the diagnosis of osteoporosis based on BMD in patients with cervical cancer who have received radiotherapy.

This study examined Tthe cooking methods foroftraditional foods called such as Mieum, Misu, and Goeum from the from investigation of old cook books and ancient literatureis as follows. There We found were 7 types of Mieum that were cooked by mixing rice and cereals, while 3 types of Mieum were cooked by mixing cereals and herbal medicines to with thenuts. The Mieums that were cooked by mixing meat, fish, and shellfish, etc. to the herbal medicine ingredients like such as medical plants, etc were consisted of 8 types. Therefore, a total of 18 types of Mieum, Misu, and Goeum, etc were have been classified. Among the cooking methods of for Mieum, rice and grains were boiled for an extended longtime and filtered with a sieve to be used as the juicebroth. The Job's tears and millet, etc were mixed into water, or boiled after being made into a powder, soaked into water, and dried. The herbal medicine ingredients such as ginseng were boiled for an extended long time, and once the ingredients are were flown out cooked down, it the broth was filtered with asieve to be used the as a liquid extract. The meat, bone, and shellfish, etc were also boiled for a longn extended time, filtered with a sieve, and made into a juice broth to be used as a drinks from on occasion time to time. These drinks, called Mieum, Misu, and Goeum above, were healthy foods our ancestors used to enjoy for enjoyment drinking, and were also food for remedyies and sources of nutritionon. As Since the meal replacement foods to that replace meals that can be eaten right away while working and studying are needed, due to is required within the our busy schedules of in modern peoplesociety, thise literary investigation and the cooking methods for of Mieum, Misu, and Goeum, which that used to be are our traditional foods, can be are used as a basic research material for the development of convenient breakfast to meal replacements breakfast.

Purpose : Because there is a difference depending on the environment as for an inspection equipment the important part of bone density scan and the precision/accuracy of a tester, the management of quality must be made systematically. The equipment failure caused by overload effect due to the aged equipment and the increase of a patient was made frequently. Thus, the replacement of equipment and additional purchases of new bonedensity equipment caused a compatibility problem in tracking patients. This study wants to know whether the clinical changes of patient's bonedensity can be accurately and precisely reflected when used it compatiblly like the existing equipment after equipment replacement and expansion. Materials and methods : Two equipments of GE Lunar Prodigy Advance(P1 and P2) and the Phantom HOLOGIC Spine Road(HSP) were used to measure equipment precision. Each device scans 20 times so that precision data was acquired from the phantom(Group 1). The precision of a tester was measured by shooting twice the same patient, every 15 members from each of the target equipment in 120 women(average age 48.78, 20-60 years old)(Group 2). In addition, the measurement of the precision of a tester and the cross-calibration data were made by scanning 20 times in each of the equipment using HSP, based on the data obtained from the management of quality using phantom(ASP) every morning (Group 3). The same patient was shot only once in one equipment alternately to make the measurement of the precision of a tester and the cross-calibration data in 120 women(average age 48.78, 20-60 years old)(Group 4). Results : It is steady equipment according to daily Q.C Data with $0.996\;g/cm^2$, change value(%CV) 0.08. The mean${\pm}$SD and a %CV price are ALP in Group 1(P1 : $1.064{\pm}0.002\;g/cm^2$, $%CV=0.190\;g/cm^2$, P2 : $1.061{\pm}0.003\;g/cm^2$, %CV=0.192). The mean${\pm}$SD and a %CV price are P1 : $1.187{\pm}0.002\;g/cm^2$, $%CV=0.164\;g/cm^2$, P2 : $1.198{\pm}0.002\;g/cm^2$, %CV=0.163 in Group 2. The average error${\pm}$2SD and %CV are P1 - (spine: $0.001{\pm}0.03\;g/cm^2$, %CV=0.94, Femur: $0.001{\pm}0.019\;g/cm^2$, %CV=0.96), P2 - (spine: $0.002{\pm}0.018\;g/cm^2$, %CV=0.55, Femur: $0.001{\pm}0.013\;g/cm^2$, %CV=0.48) in Group 3. The average error${\pm}2SD$, %CV, and r value was spine : $0.006{\pm}0.024\;g/cm^2$, %CV=0.86, r=0.995, Femur: $0{\pm}0.014\;g/cm^2$, %CV=0.54, r=0.998 in Group 4. Conclusion: Both LUNAR ASP CV% and HOLOGIC Spine Phantom are included in the normal range of error of ${\pm}2%$ defined in ISCD. BMD measurement keeps a relatively constant value, so showing excellent repeatability. The Phantom has homogeneous characteristics, but it has limitations to reflect the clinical part including variations in patient's body weight or body fat. As a result, it is believed that quality control using Phantom will be useful to check mis-calibration of the equipment used. A value measured a patient two times with one equipment, and that of double-crossed two equipment are all included within 2SD Value in the Bland - Altman Graph compared results of Group 3 with Group 4. The r value of 0.99 or higher in Linear regression analysis(Regression Analysis) indicated high precision and correlation. Therefore, it revealed that two compatible equipment did not affect in tracking the patients. Regular testing equipment and capabilities of a tester, then appropriate calibration will have to be achieved in order to calculate confidential BMD.
