Two patients with Kienbocks disease were treated with microvascular loop graft to obtain the neovascularization of the avascular lunate. After each follow-up of forty-six months and eleven months, their results were complete relief of pain, definite decrease of sclerotic change in the radiologic finding and restoration of normal range of motion. This procedure is considered as a good method to help for the treatment of the Kienbocks disease.

The authors have studied 60 cases of back pain with respect to diagnostic accuracy of myelography with metrizamide from January, 1983 to Decembar, 1984 at the Department of Orthopaedic Surgery, College of Medicine, Kyung Hee University. The results were as followes; 1. Of the 60 cases, 57 cases (95%) showed excellent and good findings of myelography. 2. In case of the marginal clearance of the nerve-sleeve in myelography, the excellent finding was 93.3%.3. The side effect of myelography was slight and 44% of all patients complained of headache, which disappeared within 24 hours after onset in 92% of them. 4. The accuracy rate of myelography with metrizamide was 89. 2%.

The aim of this study was to quantitatively estimate the effect of hypertension upon the left ventricle, using the systolic time intervals. The subjects for this study consist of 72 hospitalized hypertensive patients including 38 males and 34 females. The measurements of the systolic time intervals were obtained from simultaneous high speed recording(100mm/sec) of an electrocardiographic lead best displaying the onset of left ventricular depolarization, a carotid pulse tracing, and a phonocardiogram best displaying the initial high frequency vibrations of the aortic valve closure sound. All data were corrected for heart rate and sex using the regression equations of Weissleretal. The results were follows: 1) As the diastolic blood pressure increased, shortening of left ventricular ejection time index and prolongation of preejection period index and PEP/LVET ratio were significant. 2) As the electrocardiographic findings related to hypertension became severe shortening of left ventricular ejection time index and prolongation of preejection period index and PEP/LVET ratio were significant. 3) As the hypertensive retinopathy became severe, shortening of left ventricular ejection time index and prolongation of preejection period index and PEP/LVET ratio were significant. It was suggested that the measurement of the systolic time intervals are useful in assessing the effects of hypertension upon the left ventricular function and in detecting early recognition of cardiac dysfunction in hypertension, even though not necessarily associated with overt heart failure.

Statistical analysis of 18,211 cases of electrocardiogram which were recorded in Chung-Ang University Hospital from January 1969 to December 162% of total cases(61% of male and 63% of female) and the incidence of normal electrocardiogram was decrease with aging. 2) Abnormal Q-wave was seen in 0.4% of total cases(0.5% of male and 0.3% of female) and the incidence of abnormal Q-wave was more common over 50 years of age. 3) Left axis deviation was seen in 1.1% of total cases(1.4% of male and 0.9% of female) and the incidence of left axis deviation was more common over 50 years of age. Right axis deviation was seen in 0.3% of total cases(0.3% of male and 0.4% of female) and the incidence of right axis deviation was more common under 30 years of age. 4) Left ventricular hypertrophy was seen in 3.6% of total cases(4.8% of male and 2.5% of female) and the incidence of right ventricular hypertrophy was more common under 30 years of age. 5) ST-segment depression was seen in 2.0% of total cases(2.2% of male and 1.9% of female) and the incidence of ST-segment depression was increased with aging. 6) T-wave inversion was seen in 1.6% of total cases (1.5% of male and 1.7% of female) and the incidence of T-wave inversion was increased with aging. 7) Atrioventricular block was seen in 1.4% of total cases(1.8% of male and 1.0% of female) and the incidence of atrioventricular block was more common over 50 years of age. 8) Incidence of complete left bundle branch block was 0.2% and was more common overs 60 years of age. Incidence of complete right bundle branch block was 1.1% and the incidence was more common over 50 years of age. Incidence of incomplete right bundle branch block was 3.0% and the incidence was more common under 40 years of age. 9) The incidence of premature beat was 2.7% of total cases, atrial fibrillation 1.5%, supraventricular tachycardia 0.2%, sinus tachycardia 7.5%, sinus bradycardia 2.2% and sinus arrhythmia 2.3%. 10) Low voltage was ssen in 3.8% of total cases and the incidence of low voltage was more common over 50 years of age.

The technique of the arthroscopic total meniscectomy of discoid meniscus is very difficult. Ikeuchi(1982) reported a technique of arthroscopic total meniscectomy of the lateral discoid meniscus by removal of 2/3 of the anterior part of the meniscus first and then by morselization. The purpose of this paper is to report a technique of arthroscopic total meniscectomy of the lateral discoid meniscus as a whole. During the period from October 1982 to October 1984, we had 12 experiences of arthroscopic total meniscectomy of the discoid meniscus and found good results, that is, little postoperative pain, short period of hospitalization and early restoration of joint motion without physical therapy. Complications are 3 cases of symptomless slight lateral instability and 4 cases of hemarthrosis.

The clinical observation was made on 174 patients with congestive heart failure among the admitted patients in Chung Ang university hospital between 1971 and July, 1978. The results were summarized as follows: 1. There were 89 females and 85 males and the incidence was the highest in the 6th decade. 2. The common causes of congestive heart failure were hypertensive heart disease 44.8%, valvular heart disease 21.3% and ischemic heart disease 9.2%. 3. The precipitating factors of congesive heart failure were found in 73.6% of cases and the major factors were arrhythmia 25.3% and infection 15.5%. 4. The important symptoms and signs were dyspnea 86.8%, hepatomegaly 53.4%, pulmonary rales 49.4%, cardiac murmur 46%, tachycardia 35.1% cough 35.1% and orthopnea 34.5%. 5. The ECG findings were abnormal in 92.1% of cases and the frequent abnormal findings were inverted or flat T wave 47.3%, atrial fibrillation 40.6% and left ventricular hypertrophy 33.3%. 6. The chest PA on admission revealed abnormalities in 159 cases, including cardiomegaly 74.6%, pulmonary congestion 66.9% and pleural effusion 26.6%. 7. The major abnormalities of laboratory data were proteinuria and the increase of globuline, BUN, TTT, alkaline phosphatase and SGOT.
