Recently the internal rigid fixation with plates and screws became popular procedure. In the cases of the zygomatic fracture, it is sufficient to fix more than 2 point in many studies. Therefore, the internal rigid fixation requires the aggressive incision to expose the zygoma, such as coronal incision. Since many patients are afraid of this aggressive operation, we have provided a simple and effective method which is a 3-dimensional one point fixation on the zygomaticofrontal suture with X-shaped(6-hole) miniplate for the treatment of zygomatic fractures. From March 1995 to september 1995, we treated 13 cases of zygomatic fractures by open reduction and X-shaped miniplate fixation on the zygomaticofrontal suture. The results were as follows: 1) plane to plane contact on each side of the fracture with one point X-shaped miniplate. 2) 91.8% correction on Water's views, and 93.3% correction on zygomatic arch view with one point fixation. 3) patients were satisfied with these procedures because of minimal incision, mild edema and low operation price (short operation & anesthetic time, one plate & 6 screws cost).

To study factors related to release of atrial natriuretic polypeptide(ANP) in human subjects, instracardiac pressure and plasma ANP concentration in peripheral and central circulation were measured in patients with various heart disease (18 valvular heart disease, 4 congenital heart disease, 2 cardiomyopathy). 1) The concentration in peripheral venous plasma were increased in 14 patients with New York Heart Associaion (NYHA) functional class III-IV (87+/-38 pg/ml) as compared with that in 10 patients with NYHA functional class I-II (39+/-21 pg/ml, P<0.005)and 15 normal subjects (51+/-21 pg/ml, P<0.01). 2)The concentration of plasma ANP in inferior vena cava, right ventricle, pulonary artery, left ventricle and aorta were markedly increased in patient with NYHA functional class III-IV, elevated mean right atrial pressure (MRAP> or =8 mmHg) elevated mean pulmonary capllary wedge pressure (MPCWP> or =15 mmHg) and/or elevated pulminary artery systolic pressure (PASP> or =35 mmHg), as compared with those in patients with NYHA functional class I-II and/or lower intracardiac pressure (MRAP<8 mmHg, MPCWP<15 mmHg, and/or PASP<35 mmHg). 3) A step up in ANP concentration between inferior vena cava and right atrium was seen in patients with elevated MRAP (81+/-28pg/ml, 137+/-60pg/ml, P<0.05), MPCWP (74+/-37pg/ml,112+/-62pg/ml, P<0.05) and/or PASP (75+/-29 pg/ml,119+/-64 pg/ml, P<0.05). But there were no differences among intracardiac ANP concentrations from right atrium though aorta. 4) Plasma concentrations in right atrium, pulmonary artery, left ventricle and aorta correlated with MRAP (r=0.82, 0.63, 0.56, p<0.005 and r=0.52, P<0.01, respectively), MPCWP (r=0.86, 0.75, 0.73 and 0.72 respectively, P<0.005 in all) and PASP (r=0.73, 0.57, 0.68 and 0.59 respectively P<0.005 in all). 5) Left atrial diameter correlated with plasma ANP concentration in peripheral plasma (r=0.55, P<0.01), inferior vena cava (r=0.51, P<0.025), right atrium (r=0.45, P<0.05), right ventricle (r=0.55, P<0.01), pulmonary artery (r=0.52, P<0.01), left ventricle (r=0.55, P<0.01) and aorta (r=0.56, P<0.005). These results suggest that the heart secrets atrial natriuretic polypeptide into right atrium in response to increased mean right atrial pressure, mean pulmonary capillary wedge pressure, pulmonary artery systolic pressure and/or left atrial distention.

Holoprosencephaly(HPE), a common developmental defect affecting the forebrain and cranioface, is etiologically heterogenous. Teratogen, chromosomal anomalies, genetic syndrome, or genetic disorder of non-syndromic HPE are usually accepted as etiology. But the severity of brain and craniofacial malformation are not associated with etiology. Individuals with microform of HPE, who usually have normal cognition and brain imaging, are at the risk of having children with HPE. Several studies on the basis of HPE gene have been performed, which shed valuable insight on normal brain development. As additional HPE genes are identified, more accurate recurrent risk counseling can be given. We experienced a case of recurrent HPE diagnosed by transabdominal ultrasound examinations at 22 weeks' gestation.

Taussig-Bing anomaly is infrequently associated with interrupted aortic arch and size discrepancy of great arteries makes it difficult to undergo arch recons- truction and arterial switch operation. A 20-day old male infant was admitted with the diagnosis of Taussig-Bing anomaly with type B interrupted aortic arch. Multi-organ failure, due to the diminution of ductal flow, was stabilized after 3 weeks of prostaglandin E1 and controlled ventilatory support. The surgical correction consisted of VSD closure, arterial swtich and extended aortic arch reconstruction. The marked disparity between the hypoplastic ascending aorta and the dilated main pulmonary artery was overcome by constructing distal neoaorta using both native ascending and descending aortic tissue. The patient was extubated on postoperative 2nd day. Postoperative catheterization showed no left ventricular outflow obstruction, no intracardiac shunt, and no incompetence of neoaortic valve.
