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%).

After reconstruction of anterior cruciate ligament, increased idameter of femoral or tibia1 bone tunnel has been obsened on plain radiogram. The etiology of radiographic tunnel enlargement is not well understood and the significance of this tunnel enlargement is unknown. This retrospective study reviewed tibial tunnel diameter in 34 cases of anterior cruciate ligament reconstructions. And we evaluated the correlation between the tibial tunnel enlargement and the position of screw fixation, instability, choice of graft, and clinical results at 1 year postoperatively. AII operation was per formed using a single incision technique. After 3 or 4 months and one year after operation, the diameter of tibial tunnel was measured with digital caliper on the plain radiogram. Tibial tunnel sclerotic margins were measured in the level Of medial tibial plateau on the lateral view of knee. Average tunnel enlargement of 3 allografts was 1.62mm and that of 15 autografts was 2.03mm. No significant difference was seen in KT-10000 arthrometer measurements between enlarged group (amount of enlage-ent >+1 S.D) and not-enlarged group (less than +1 S.D). No coelation was present between the increased tunnel diameter and Lysholm score. Cases with 10mm or more vertical distance between the most proximal point of tihial interference screw and the level of m4eial tibial plateau had average 1.15mm tibial tunnel enlargement and cases with less than 10mm vertical distance ha & I average 2.52mm tibial tunne] enlargement;the difference was not significant (P>0.05). The tibial tunnel enlargement was not correlated with position of screw, clinical results, stability of knee. The tibial tunnel enlargement was not caused hy only mechanical factor such as motion of intra-tunnel portion of graft-tendon.

The original technique for endoscopic anterior cruciate ligament reconstruction has several potential complications because of constraints imposed by working through the tibial tunnel: improper femoral tunnel placement, violation of the femoral tunnel posterior wall, femoral interferenc screw divergence, graft laceration during screw insertion, and distal tibial bone block prr>trusion. We performed 25 endoscopic anterior cruciate ligament reconstructions with bone-tendon-bone graft using a mo3ified technique that minimizes each of these problems, through the use of a anteromedial portal more centrally and distally placed than the original that portal. Postoperative radiographic review showed femoral screw divergence in 20% of cases (2 in the anteroposterior plane, 2 in the lateral plane and 1 in both planes), but the average angles (AP: 0.52+- 1.85, Lateral: 1.48+-3.30) were insignificant. There was no graft damage during screw insertion or grafttunnel mismatch. We concluded that this modified technique allows simplified, reproducible tunnel and interference screw placement.

To evaluate the intra-articular pathology of popliteal cysts of knee, we performed arthroscopy on patients with popliteal cysts between February 1992 and February 1995. Thirty-one patients (32 cases) have been treated by excision of cyst after arthroscopy. Mean duration of follow-up was 15 months (13-19 months). Location of cysts was in the right knee in 17 cases, in the left knee in 13 cases, and bilateral in one case. Pain or swelling was present in 12 (38%), giving-way was reported by 4 cases. Three cases revealed quadryceps atrophy. The McMurray test was postive in 6 cases. After arthroscopy, the cysts were excised. Ninteen cases (59%) had associated intra-articular lesions: seven medial meniscal tears, two lateral meniscal tears, seven had chondral damages, one had medial plica syndrome, and one had rheumatoid arthritis, Communication between the cyst and the knee was present in 7 cases (22%), all of whom were over 40 years of age. Thirteen cases was younger than 30 years of age, and 11 cases of these cases had no intra-articular pathology. Two other cases had lateral meniscal tears and medial plica syndrome, respectively. We recommend arthroscopy in middle and older aged patients with popliteal cysts for evaluating and treating intra-articular lesions.

Polyarteritis nodosa is one of the necrotizing vasculitis inv'olving small and medium sized arteries. Polyarteritis nodosa may affect many organs such as kidney, musculoskeletal system, gastrointestinal tract, skin, heart, and nerve. In Cupps and Fauci's autopsy studies, muscle involvement was found in 39% of the patients with polyarteritis nodosa. Commonly Polyarteritis nodosa may be presented clinically by myalgia. We experienced a case of polyarteritis nodosa presenting as myositis, diagnosed by muscle biopsy and renal angiography, which appear with unusual presentation of joint contracture in lt elbow and muscle crarnping pain rather than cornmonly presented myalgla.

Granuloma pyogenicum is a benign vascular tumor and usually occurs as a single lesion. But in a few instances, the development of multiple satellite lesions has been observed following excision or irritation of the primary lesion. Multiple satellite granuloma pyogenicum is a very rare variant of granuloma pyogenicum and occurs most commonly on the back, chest, or trunk, particularly in the interscapular region during childhood. We report a case of multiple granuloma pyogenicum which occurred on the unusual site of the scalp in a 70-year-old woman. The patient presented with a reddish pedunculated nodule with multiple satellite lesions on the right temporal area. The histopathologic findings of the primary and satellite lesions showed many newly formed capillaries and characteristic epidermal collarettes. The lesions were treated by surgical excision and electrodesiccation.

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.

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.
