Background: Abdominal compartment syndrome has multiple etiologies that are not only related to trauma but also any problem condition in the absence of abdominal injury. To determine whether prevention of the abdominal compartment syndrome after celiotomy for trauma victims justifies the use of temporary abdominal coverage with monofilament knitted polypropylene mesh (Malex mesh) in severely injured patients. Method: Medical records at the Ajou University Medical Center were reviewed for a 32-month period from May 1st, 2002 to December 31st, 2004. Twenty-nine consecutive patients requiring celiotomy who were survived until at the end of celiotomy received temporary abdominal coverage and staged abdominal repairs with Malex mesh. One of them was dissecting aortic aneurysm patient and the others were all trauma victims. Malex mesh prosthesis coverage was used in cases of abdominal compartment syndrome due to excessive fascial tension, severe bowel edema and retroperitoneal hemorrhage or edema followed by staged abdominal repairs. Result: Eighteen of twenty-nine patients were survived. Demographic characteristics, injury severity number of abdominal-pelvic bone injuries, mortality rate, complications, number of operations for permanent closure, required time for permanent closure showed no difference between man and women or child and adult. Except one dissecting aortic aneurysm patient, trauma cases showed $3.24{\pm}0.98$ injury sites. All cases that received temporary abdominal coverage and staged abdominal repairs did not show abdominal compartment syndrome. $10.08{\pm}5.85$ days and $2.27{\pm}0.82$ times of operation required making permanent abdominal closure after temporary abdominal coverage followed by staged abdominal repairs. Most of surviving patients have shown antibiotic-resistant organism and fungus infection. Patients who received permanent closure recovered from infectious problem completely. Conclusion: The use of Malex mesh for temporary abdominal coverage in severely injured patients undergoing celiotomy was effective treatment method.

Purpose: Sensory changes in the upper limb are complications of a mastectomy with immediate breast reconstruction with the treatment of breast cancer. The purpose of this study is to clarify whether immediate breast reconstruction worsens the sensory changes. Methods: From March 2004 to December 2005, 20 patients who had a mastectomy with immediate breast reconstruction(reconstruction group) were compared with 23 patients who had a mastectomy alone(control group). All patients had stage I or II breast cancer. The sensory changes were assessed in a blind manner by one examiner that used light touch sensation, static two-point discrimination, pain, vibration, hot and cold temperature perception. The sensory changes were identified along the sensory dermatome for diagnosing the damaged nerves. The following factors and their relationship with the sensory changes were analyzed : age, complications, and the mastectomy method. Results: There was no statistical difference in the static two-point discrimination, pain, vibration, hot and cold temperature perception between the two groups. However, the ability to recognize light touch was significantly better(p=0.045) in the reconstruction group than in the control group. The main site of sensory change was the proximal and medial portion of the upper limb in both groups. At these sites, the mean value of Semmes-Weinstein monofilament was $1.01g/mm^2$(reconstruction group 0.82, control group 1.17) and 2-point discrimination was 51.74(converted to perfect score of 100; reconstruction group 42.50, control group 59.78). The total rate of early complications was found to be significantly lower(p=0.006) in the reconstruction group than in the control group. Conclusion: These findings suggest that an immediate breast reconstructive procedure following a mastectomy is as safe as or safer than a mastectomy alone with respect to postoperative sensory changes of the ipsilateral upper limb.

Background Nipple-sparing mastectomies (NSMs) are increasingly performed to obtain the best aesthetic and psychological outcomes in breast cancer treatment. However, merely preserving the nipple-areolar complex (NAC) does not guarantee a good outcome. Darkly pigmented NACs and a tendency for poor scarring outcomes are particular challenges when treating Asian patients. Herein, we review the reconstructive outcomes following NSM at Singapore General Hospital. Methods All breasts reconstructed following NSM over an 11-year period from 2005 to 2015 were reviewed. Information was collected from the patients' records on mastectomy indications, operative details, and complications. Patient satisfaction, breast sensation, and aesthetic outcomes were evaluated in 15 patients. Sensation was quantified using the Semmes-Weinstein monofilament test. Results A total of 142 NSMs were performed in 133 patients for breast cancer (n=122, 85.9%) or risk reduction (n=20, 14.1%). Of the procedures, 114 (80.2%) were autologous reconstructions, while 27 (19.0%) were reconstructions with implants. Complications occurred in 28 breasts (19.7%), with the most common complication being NAC necrosis, which occurred in 17 breasts (12.0%). Four breasts (2.8%) had total NAC necrosis. The overall mean patient satisfaction score was 3.0 (good). The sensation scores were significantly diminished in the skin envelope, areola, and nipple of breasts that had undergone NSM compared to non-operated breasts (P<0.05). Half of the subset of 15 patients in whom aesthetic outcomes were evaluated had reduced nipple projection. Conclusions Immediate reconstruction after NSM was performed with a low complication rate in this series, predominantly through autologous reconstruction. Patients should be informed of potential drawbacks, including NAC necrosis, reduced nipple projection, and diminished sensation.

국내에서 심장, 폐이식이 각 대학병원에서 점차 확산 시행되고는 있으나, 이에 따른 기초실험이 뒷받침되지 않고, 큰 동물에서는 많은 실험비용이 들어 보다 적은 동물을 이용하게 되었으나 이 방법은 현미경하의 미세수술기법의 발달과 더불어 발전하게 되었다. 본 연구는 현미경하의 미세수술기법으로 쥐모델에서 복부의 대동맥과 하공정맥에 다른 쥐의 공여심장의 대동맥과 폐동맥을 각각 문합술로 연결하는 방법으로 이식하여 동종이형의 장기이식에 따른 거부반응과 면역억제제를 투여하여 그에 따른 생존율을 비교하고자 하였다. 체중 150∼250 gm의 흰쥐의 심장을 공여 및 이식하는 바, 이소성의 심장이식후 면역억제제를 투여하지 않은 군과 면역억제제를 투여한 군으로 나누고, 각 군에서 복부에 이식된 심장의 박동을 매일 만져보고서 만져지지 않을 경우는 이식된 심장이 거부반응에 따른 것으로 판단하여 이의 생존율을 비교 검토하여본 바, 면역억제제를 투여하지 않은 군에서보다 투여한 군에서 오래 생존하여 동종이형의 이식에서 면역억제제를 투여하므로써 장기이식에 따른 장기성적을 향상시킴을 알 수 있었다.

감각장애는 뇌졸중에서 흔히 나타나며, 발에서 나오는 촉각의 감각정보는 균형을 위해 중추신경계에 중요한 정보를 제공한다. 본 연구의 목적은 뇌졸중 환자의 발바닥 감각역치와 균형의 상관관계를 연구하는 것이다. Semmes-Weinstein Monofilaments를 사용하여 발바닥의(엄지발가락과 뒤꿈치) 감각역치를 평가하였다. 균형은 버그균형척도와 MTD system을 이용하여 정적 선 자세와 앉은 자세에서 일어서기 동안의 마비쪽과 비마비쪽의 체중 분포 정도를 측정하였다. 정적 선 자세와 앉은 자세에서 일어서기 동안 체중 분포 정도는 비마비쪽보다 마비쪽에서 더 낮았다(P<0.05). 버그균형척도는 36.00±1.53이었다. 마비쪽의 엄지발가락 감각역치는 버그균형척도(r=-0.444, P<0.05), 정적 선 자세(r=-0.332, P<0.05), 앉은 자세에서 일어서기(r=-0.390, P<0.05)와 상관관계가 있었다. 마비쪽의 뒤꿈치 감각역치는 버그균형척도(r=-0.467, P<0.05), 정적 선 자세(r=-0.532, P<0.05), 앉은 자세에서 일어서기(r=-0.516, P<0.05)와 상관관계가 있었다. 이러한 결과는 발바닥의 높은 감각역치가 균형 능력 저하에 영향을 미칠 수 있음을 시사한다. 앞으로 뇌졸중 환자의 감각 역치에 대한 연구는 뇌졸중 환자의 재활과 감각 평가에 도움이 될 것이다.
