The authors analyzed data from 15 patients with idiopathic dilated cardiomyopathy to evaluate the hemodynamic changes and left ventricular cineangiogram as compared with normal control. Mean right atrial pressure, right ventricular systolic pressure, mean pulmonary artery pressure and mean pulmonary wedge pressure were signigicantly elevated in patients with dilated cardiomyopathy. Left ventricular enddiastolic volume was increased in idiopathic dilated cardiomyopathy(139.9+/-58.73 ml/m2). Cardiac index, left ventricular ejection fraction and circumferential fiber shortening were significantly reduced in patients with dilated cardiomyopathy as compared with normal control(p<0.001). Hypokinetic, diffuse wall motion abnormalities of left ventricle were common in idiopathic dilated cardiomyopathy. A few cases of akinetic or dyskinetic segmental wall motion abnormalities were present. Left ventricular configurations in patients with idiopathic dilated cardiomyopathy were globe shape(53.4%) as compared with pear core shape(90%) of normal control. Associated mitral regurgitations in patients with idiopathic dilated cardiomyopathy confirmed by left ventricular cineangiogram were 53.3 percent. Mild to moderate mitral regurgitations were often present(46.6%).

Vitreous surgery has become a widly practiced procedure for use in the variety of pathological conditions in the anterior and posterior semgment of the eye. The goal of the vitreous 'surgery is to clear the optic pathway and restore the anatomy and function of the eye. Vitreous surgery was performed in 28 eyes using the O'malley ocutome from April, 1980 to October, 1980. Among the 28 eyes, 14 eyes received anterior segment surgery and the other 14 eyes received posterior segment surgery. The follow up period after surgery ranged from 3 weeks to 7 months and the average period was 4 months. The conditions requiring surgery were as follows: 9 eyes had Reconstruction of anterior segment after trauma; 4, removal of pupillary membrane due to chronic uveitis and after cataract; and 1, anterior vitrectomy with removal of subluxated lens. As for the causes of posterior segment surgery, 5 eyes had trauma of eyeballs; 3, hypertensive retinopathies; 2, vitreous opacity with retinal detachment; 1, diabetic retinopathy; 1, central retinal vein occlusion; 1, nonmagnetic intraocular foreignbody; and 1, lost lens nucleus into the vitreous. The improvement of visual acuity after surgery was seen in 14 eyes (50%), 9 eyes in anterior segment surgery and 5 eyes in posterior segment surgery. The complications during operation were vitreous hemorrhage (1 eye; 3.5%), retinal detachment (2 eye; 7%), and traumatic cataract (1 eye; 3.5%). Postoperative complications were phthisis bulbi (1 eye; 3.5%), and cataract (1 ; 3.5%). We found that vitreous surgery is not only useful to removal of the various pathologic conditions of vitreous through the pars plana approach but in anterior segment as an emergency procedure at the time of trauma and vitreous loss during anterior segment surgery.

There have been much limitations and errors in evaluating prostatic conditions by traditional radiologic methods due to its location and anatomical structure. However recent introduction and improvement of the ultrasonography have been enabled us to visualize boundary of the prostate clearly and differentiate the variable findings within the prostate. Transrectal or transurethral ultrasonography of the prostate is popular nowadays, however we performed suprapubic ultrasonography of which merits are traumatic to the patients, easy to perform and it requires no adjustments or additions to basic ultrasound equipment. In order to evaluate ultrasonogram of the prostate in patients with prostatic diseases and normal adults and compare preoperative volume of the prostate on ultrasonographic estimation with postoperative volume, 31 patients with prostatic diseases and 40 normal adults under the age 60 were studied with suprapubic ultrasonography. The results obtained were as follows. 1. On ultrasonographic picture of the prostate, normal adults showed symmetrical or triangular or elliptical appearance and there were numerous fine homogenous spots within the prostate. BPH patients showed symmetric, round or oval shapes and its margin was smooth and numerous fine spots were seen within the prostate as normal adults. The prostatic size enlarged and elevated to the bladder base. Advanced prostatic cancer patients showed dyssymmetric irregular appearance. The prostate of acute prostatitis patients resembled normal prostate but prostatic size enlarged. 2. The mean prostatic volume of normal adults on ultrasonographic estimation was 21.30+/-24.80 cm3 and there were no differences of the prostatic volume between ages. 3. The mean prostatic volume of 21 BPH patients on ultrasonographic estimation was 46.2+/-17.2 cm3 and majority patients were in 33.49-61.56 cm3. 4. Comparisonal studies between preoperative ultrasonographic prostatic volume and resected prostatic volume showed correlation coefficient 0.98 (P<0.005) and mean error rate 17.58+/-8.1%. Most cases showed preoperative prostatic volume was larger than the postoperative volume which was probably due to inadequate removal of tissue and surgical capsule. As results of the above, the suprapubic ultrasonography was helpful in differential diagnosis of the prostatic diseases and estimation of the prostatic size.

Marfan's syndrome is a widespread disturbance of mesodermal tissue throughout the body. The main disturbances are characteristic skeletal anomaly, cardiopathy and eye disturbance such as lens dislocation, glaucoma, etc. Marfan originally described it under the name of dolichostenomelie in 1896. Since then, many cases have been reported in the literature. Authors experienced 3 cases of Marfan's syndrome and 2 cases were operated. The result of surgical treatment. other clinical findings, and brief review of literature are reported as following.

Spontaneous renal rupture is relatively uncommon entity. In Korean literature, 8 cases have been reported. We experienced 1 case of spontaneous renal rupture secondary to hydronephrosis caused by metastatic adenocarcinoma of undetermined origin invading upper ureter and presented it with a brief review of literature.

Despite the progress in the treament of the subretinal neovascular membrane(SRNVM) by the development of laser photocoagulation, it has been reported difficult to manage with laser photocoagu1ation on which developed in high myopic eyes: first, their location in relation to the foveola is usually difficult to discriminate; second, subretinal neovascular m6mbrane developes very close to the foveola; third, the atrophic photocoagulation scar may extend to the foveola. The interferone alpha 2a has been known to suppress angiogenetic activity, and its application to subretinal neovascular membrane in high myopia has been suggested. The effect of interferon alpha 2a on neovascular membrane in high myopia was investigated by the authors. Subjects included 16 eyes with interferon treament and 12 eyes as control who had been followed for 3 months or longer. The median total dose in these patients was 75 X 10(6) units, given over a six- to eight-week period. In the interferon treament group, the activity of neovascular membrane decreased in 9 eyes(56%) and the visual acuity improved in 7 eyes(44%). In contrast, the control group showed a sustained activity of neovascular membrane and the visual acuity was improved in only one eye(6%). Therefore, interferon alpha 2a can be considered as an alternative method in the management of the some subretinal neovascualr membrane in high myopia which is resistant to the other treament.

The coronary artery cross sectional area (CSA) is proportional to LV mass. We have measured the cross sectional area of the left and right coronary arteries in patients with ischemic heart disease to see whether it is related to the change in the LV mass. The following results were obtained ; 1) There were no significant difference in mean CSA of coronary arteries and LV mass determined by echocardiography and cineangiography between control and ischemic heart disease. 2) There were significantly increased ratio of left ventricular mass by cineangiogram to CSA of left anterior descending coronary artery in patients with myocardial infarction as compared with control group. 3) A linear relation between LV mass by cineangiogram and CSA of left coronary artery was noted in control group (r=0.53, P<0.05) and ischemic heart disease group (r=0.51, P<0.05). 4) A linear relation between LV mass determined by echocardiography and CSA of left coronary artery was noted in control group (r=0.55, P<0.05).
