We investigated the factors which influence the musculoskeletal symptoms in diagnostic medical sonographer. The Korean Society of Medical Sonographer conducted a survey through e-mail. Of the 400 subjects, 124 subjects responded(31%). The number of abdominal sonographer was 72(71.3%), obstetrics sonographer was 20(19.8%), echocardiographer was 9(8.9%) for effective 101 participant among themselves. According to the NIOSH diagnostic criteria, 86 subjects(85.1%) had musculoskeletal symptoms on their shoulders/neck, 73 subjects(72.3%) on their hands/wrists/arms/elbows, 44 subjects(43.6%) on their lower back. The factor of musculoskeletal symptoms were analyzed by the logistic regression analysis. The factors of symptoms for the hands/wrists/arms/ elbows were official autonomy, number of scans performed per week. The factors of symptoms for the shoulders/neck and the lower back were work break. However scan type were not observed as a significant factor. The study came to conclusion that many study subjects experienced musculoskeletal symptoms. These measures should be taken properly and promptly by the hospital's administrators.

A hemangioma at a cardiac valve leaflet is a rare finding. There are only five reported cases in the medical literature and no prior case reported in Korea. A previously healthy 45-year-old woman presented with an acute episode of numbness in the left side of the face and hand. Although no definite abnormalities were found on the neurological examination and testing the echocardiography revealed an echogenic mass in the anterior mitral valve leaflet. The tumor was excised en bloc from the leaflet and the defect was repaired with an autologous pericardial patch. Pathology examination confirmed the mass to be a hemangioma of the valve leaflet. Here we report this case and review the medical literature.

A 51-year-old male was admitted three month previously with a cardiac stab injury and he underwent direct cardiac repair He had no problem after this event. He complained of dyspnea that stalled 2 months after the original injury. Echocardiography showed severe tricuspid regurgitation and so, chordac replacement and ring annuloplasty was performed. Herein we report on a case of tricuspid valve repair for treating tricuspid insufficiency following a cardiac stab injury.

Rhabdomyoma is the most common benign cardiac neoplasm in neonates. Most patients with rhabdomyoma experienced spontaneous regression. Yet some of them need surgical therapy because of hemodynamic problems of the heart such as arrhythmia, outflow tract obstruction and valvular dysfunction. We found multiple masses in both ventricles on the patient's fetal echocardiogram. Heart failure caused by severe left ventricular outflow tract obstruction quickly presented after birth. The mass interfering with the outflow tract was resected via the transaortic approach at the first day of birth. Postoperative echocardiography showed complete release of the outflow tract obstruction. He was discharged on the postoperative day 8. During the 3 years of follow up, we found that the sizes of the remnant masses had gradually decreased.

Nowadays, in many fields of medical treatment, we can make an observation and a diagnosis of inward disease without using a surgical operation. As one of them, ultra-sound diagnosis system can be available widely in its cost and size compared with other medical instruments. This system also make it possible for us to see the inner parts of the body in real time harmlessly for a long time. So it can be utilized to inspect the movement of heart or fetus and to diagnose an internal disease of the soft tissues. Ultra-sound images can be generated by the reflexive and scattered wave through the pulse generator and so in ultrasound images there exist inherently many affective noised signals. In this paper, we are to take an noise-restrained image and to extract a more affective regions of the images.

Thirteen year old boy who had been stabbed in his left chest by the knife was transferred to our department from a general hospital, because of the massive bleeding from the intercostal tube drainage. Chest X-ray showed homogeneous density in the left lung field. He was confused and his vital signs were unstable. He was moved into a operating room as soon as possible. After resuscitation, his lacerated left ventricle wound was sutured through median sternotomy. The interventricular shunt was detected with intraoperative transesophageal echocardiography. The traumatic ventricular septal defect was closed via left ventricle using Dacron patch. His postoperative course was uneventful, and he was discharged with small residual shunt.

질병과 관련된 인간의 노력은 병의 치료보다는 몸의 이상 유무를 빠르게 진단하는 것과 이를 통한 예방에 초점을 맞춰져 있다. 이를 위해 혈액과 소변 검사등과 같은 검사부터 시작해서 초음파와 CT등 다양한 진단 기기가 발전되어 왔다. 그러나 인체는 스스로 자신의 질병 유무에 대한 인체의 생체 신호를 몸밖에 나타내게 되어 있다. 이를 해독하여 질병을 진단하는 것이 한방에서 주로 사용하는 방법이다. 따라서 본 논문에서는 한의학에 있어서 생체 신호를 해석하는 4대 질환 진단 방법 중 가장 중요한 망진(望診)에 대해 기술하고자 한다. 특히, 인체의 중심 기관인 심장에 대해 망진을 IT기술로 구현하고자 한다. 심장은 오관중 혀와 관계가 되어 있으며 따라서 심장에 대한 인간 생체 신호 해석시 혀는 중요한 분석 기관이 된다. 이를 위해 혀를 통해 인간의 생체 신호에 대한 결과를 반영하여 심장의 질환 여부에 대한 정보를 제공하여 주는 설진 시스템을 구축하고자 하며 우선적으로 본 논문은 얼굴 영상에서 혀 영역을 추출하는 방법에 대해 제안하고자 하며 실험에 의해 제안한 방법의 유용성을 입증하고자 한다.

Hypertrophic cardiomyopathy (HCM) is the most often seen type of cardiomyopathy in cats. The cause is unknown but a genetic basis is thought to underlie some cases. Thromboembolism (TE) is a troubling complication in cats with myocardial disease. Two cats referred to Seoul National University Hospital for Animals with the paralysis of bilateral hindlimbs after vomiting. The cats were depressed and the bilateral hindlimbs were cyanotic, cool and painful. Heart murmur sounds were auscultated in both cases. Through radiographic and echocardiographic evaluation, HCM was diagnosed. TE at the distal aortic trifurcation was also visualized on abdominal ultrasonography. Both cats were expired and HCM and saddle thrombus were confirmed by postmortem examination in one cat.
