Surgical treatment of partial endocardial cushion defect was accomplished in Feb. 1984 in this department. The 5 year old male patient had history of frequent upper respiratory tract infection and since his age of 3 years dyspnea on exertion and palpitation were noted but there were no cyanosis and clubbing. A thrill was palpable on the apex and grade IV/IV harsh systolic ejection murmur and diastolic murmur was audible on it. Liver was palpable about 3 finger breadths and no ascites. Chest X-ray revealed increased pulmonary vascularity, moderate cardiomegaly [C-T ratio; 0.69], and enlarged left atrium. EKG showed first degree heart block, RVH, LVH, and LAD. Echocardiogram showed paradoxical ventricular septal movement and abnormal diastolic movement of the anterior leaflet of mitral valve. Right heart catheterization resulted left to right shunt [Qp:Qs:2.1:1 ] and moderate pulmonary hypertension [60/40 mmHg]. Left ventriculogram showed mitral regurgitation [Grade III/IV] and filling of left atrium and right atrium nearly same time. Operative findings were: 1.Primum type atrial septal defect [3x2 cm] 2.Cleft on the anterior leaflet of mitral valve. 3.No interventricular communication and cleft of tricuspid valve leaflet. The mitral cleft was repaired with 4 interrupted sutures. The primum type atrial septal defect was closed with Dacron patch intermittently at endocardial cushion and continuously remainder. The post operative course was uneventful and discharged on 22nd postoperative day in good general conditions.

This 27 year-old male patient had severe mandibular prognathism (right and left mesio-occlusion were 0.4㎝ and 1.2㎝ , respectively). He had good oral health relatively exception of missing teeth. We examined all of his oral and skeletal status with full mouth x-ray taking, study model, and cephalogram. His general condition was good but above examination indicated the surgical operation for the mandibular prognathism. His laboratory tests were within normal limits. We determined surgical operation which was done by extraoral approach bilaterally. Incisions were made bilaterally 1.5㎝ beneath the inferior border of the mandible in the selected area and then the inferior border of the ascending rami was exposed. Retracting the periosteum to the lingual and buccal a slight amount, the cut in the bone was performed by use of bone drill. Avoiding T.M.J. troubles, the proximal segmant was not fixed to anterior segment, being in overlapping state buccally, in order to expect a natural healing by the environmental muscles and ligaments. We had immobilization with intermaxillary fixation by using the multiple Stout's method. He was discharged 17 days after operation. His general condition and operation results were good and satisfactory.

From June 1987 to January 1991, 24 patients with moderate or massive pericardial effusion underwent subxiphoid pericardial window procedures for diagnosis and therapy. The patients` ages were ranged from 28 years to 71 years. The underlying diseases were chronic renal failure with long term hemodialysis in 3 cases, malignant lung cancer in 7 cases, stomach cancer in 2 cases, tuberculous pericarditis in 5 cases, pyogenic pericarditis in 2 cases, myxedema in one case, one metastatic squamous cell carcinoma from unknown origin and three of undefined etiology. Preoperative diagnoses of pericardial effusions were confirmed by echocardiogram in all cases. Subxiphoid pericardial drainages were performed under general[n=19] or local anesthesia[n=5]. Histological diagnoses were made from the inferior pericardial tissue in all cases except one. In this one case[tuberculous pericarditis], the subxiphoid pericardial approach was failed from intraoperative bleeding. There were two postoperative death, one[in malignant lung cancer] had postoperative ventricular tachycardia which result in cardiac arrest, and the other[unknown origin metastatic malignant effusion] had persistent tachyarrhythmia postoperatively and died on postoperative 5th days. Twenty three patients were followed up from 3 days to 9 months; mean follow-up day was 43 days. The preoperative and postoperative mean cardiothoracic ratio in chest x-ray were 0.69 and 0.52 respectively. Subxiphoid pericardial drainage may provide definitive diagnosis and treatment for pericardial effusions. The approach through subxiphoid pericardium under general or local anesthesia avoids the complications of pericardiocentesis and is effective for malignant pericardial effusion.

To compare the effectiveness of the hemisling, bobath sling, extension-type sling, and the newly designed Modified Triangular Bobath Sling with Distal Support on a hemiplegic shoulder subluxation. Fourteen hemiplegic patients with shoulder subluxation were evaluated by a simple X-ray with and without the slings and the vertical and horizontal distances on the plain AP views were measurement. The newly designed arm sling was compared in terms of the effects of correction with distal support attached with shoulder saddle sling. The arm sling designed for this study was developed for the purpose of maintaining patients hands in a functional position and performing ROM exercise of the shoulder easily, and prevention or correction to shoulder subluxation. The mean values of the vertical and horizontal distance were compared to determine if there was significant difference of function between the new sling and the conventional slings. The new sling provided the patients with good vertical correction of the subluxation(p<0.05) but did not increase the horizontal distance significantly. These results support the effectiveness of a new sling to decrease subluxation in hemiplegia. Further study on the long term effects or complication of the new sling is recommended.
