The authors experienced a case of secondary glaucoma combined with mesodermal dysgenesis of anterior segment, which disclosed extensive peripheral iridocorneal adhesion of congenital origin while his fellow eye revealed a sclerocornea. This case is extremely rare and entirely different from the previously reported Axenfeld's and Rieger's anomalies. We report this interesting case with brief review of the literatures.

Intravascular injection of hydrogen peroxide produces oxygen microbubbles suitable for echocardiographic contrast enhancement. To evaluate the effect of a method of myocardial contrast 2-D-echocardiographic delineation of myocardium during acute coronary occlusion, injection of a fresh mixture of 2ml of 0.2% H2O2 and 1ml of heparinized dog blood into aortic root were made in 12 poenchest dogs 10 minutes after occlusion of left anterior descending coronary artery distal to the first diagonal branch and left ventricular short axis 2-D echocardiographic images at the midpapillary muscle level were obtained. On injection of H2O2 blood mixture normally perfused myocardium was enhanced in echodensity but the area of malperfusion did not change in echodensity. The borderlines between the area of normal perfusion and malperfusion was well delineated. The malperfused area measured at mid papillary muscle level by planimetry area method was 29.7+/-6.0% and 32.6+/-6.7% by endocardial circumferential length method. There was a linear correlation between planimetric estimate of area of malperfusion by H2O2 contrast echocardiography and visual determination of regional wall motion abnormality by 2-D echocardiography(r=0.93, P<0.001). There was no change in heart rate before, during and after H2O2 injection. Infection of H2O2 blood mixture caused bradycardia(8.3%), second degree A-V block(16.6%) and ventricular fibrillation(8.3%). H2O2 clearance was achieved in 3-10 minutes. These findigs suggest that H2O2 enhanced myocardial contrast ehocargiography using 2ml of 0.2% H2O2 and 1ml of blood muxture is an accurate, reproducible, real-time in vivo method of quantifying the extent of myocardial perfusion defect during acute coronary occlusion in dog.

We report a case of cutaneous calcinosis following extravasation of calcium calcium chloride in a 3-week old neonate, After extravasation of 3% calcium chloride infusion, rapid and marked swelling, erythema, and signs of soft tissue necrosis developed over the extensor surface of both upper extremities. Through the small channels of the destroyed epidermis, tiny white pieces of calcific masses were eliminated spontaneously. Histologically the calcium deposits were found as amorphous masses in the upper dermis and the discharge of calcium deposits also took place by means of transepidermal elimination. The central bone formation and surrounding calcium deposition were present along with dense lymphohistiocytic cell infiltration in the deep dermis. Complications of extravasation of calcium solution during intravenous infusion included localized calcification and, ocasionally necrosis. The incidence of compllcations was about eight percent. This is a case which again emphasises of the danger of using calcium chloride intravenously in the neonate or young infant.

BACKGROUND: Balloon PTCA for the distal, long, eccentric coronary artery stenosis will be at high risk for severe dissection or acute occlusion during or after procedure. METHODS AND RESULTS: High Speed Rotational Atherectomy followd by low pressure balloon angioplasty due to distal, long, eccentric coronary artery stenosis. Rotational coronary atherectomy debulked the lesion quickly without difficulty. Rotational Coronary Atherectomy with adjuctive low pressure balloon inflation was successful without event. CONCLUSIONS: This case illustrates the point that complementary deployment of devices may not only improve success of percutaneous coronary intervention, but also may extend its scope.

Small hepatoma is defined as hepatocellular carcinoma less than 3cm in maximum diameter and fewer than 3 innumber. To assess the ability of ultrasound to detect small hepatomas, a prospectively study was done in a groupof patients with HBsAg-positive chronic hepatitis and liver cirrhosis. Herein, we present 4 hypoechoic smallhepatomas detected on ultrasound and emphasize the role of real-time ultrasonography as a practical test formonitoring hepatoma high-risk, subjects.

A oral inotropic agent, denopamine(TA-064, (-)-alpha-(3,4-dimethoxyphenethyl aminomethyl)-4-hydroxybenzylalcohol), was shown to have strong positive inotropic effect in experimental animals. To determine effects of denopamine on the left ventricular9LV) function and clinical features in patients with severe chronic heart failure who were treated with conventional regimens, denopamine(5mg 3 times per day for 4 weeks) was administered orally to 28 patients with chronic heart failure(22 dilated cariomyopathy, 6 ischemic heart disease) and systolic time interval, 2-D and Doppler echocardiognaphy were performed to evaluate LV function. Denopamine had no effect on LV dimension, volume and fractional shortening, and produced modest increase of ejection fraction and cardiac index, and modest decrease of PEP/LVET and cardiothoracic ratio in the cheat X-ray(PA view). The stroke volume was significantly increased (32.8+/-10.0 to 36.4+/-11.1 ml, p<0.05). Systolic BP was decreased (131.3+/-32.7 to 123.2+/-20.8 mmHg, p<0.05) with little change in diastolic BP and heart rate. Subjective symptoms and NYHA functional class were improved (71.4%, 67.9%, respectively). No adverse effect and ECG abnormality were noted. In conclusion, the addition of denopamine to conventional therapy improved clinical symptoms and caused modest increase of LV contractile function in patients with severe chronic heart failure without significant untoward effects. Therefore, the addinion of denopamine to conventional therapy may be an effective and safe method for the treatment of chronic congestive heart failure.
