The author operated 34 cases of pterygia by Newton's method, wihich combined Mc Raynold's transplantation with limbal incision, in these 34 case, 4 cases were recurred, and in other 2 cases, a few vessels only found on the operated area of the cornea. Among these 6 cases, one had trachoma, 3 had chronic cat conjunctivitis. Auther thinks that the chronic inflammation such as trachoma or chronic conjunctivitis is very important factor in the recurrence of pterygia. This fact also encourages the author who believes that the inflammation is rather more important factor in the etiology of the pterygia than the degensration.

We are Presenting of two cases of Marfans syndrome. First acse; 22 year old boy, height 262 cm, weight 40.9 kg, typical skeleton, hands and feet. The span of the outstreched arm, from right finger to the other, is 165 cm, exceeds by 3 cm than the height. Abnormal flexibility of Joints in the both thums. Vision; O.D. 0.1 with-sph.7.0 D., O.S. 0.0 with-sph.6.0 D. Lens; typically dislocated, upward and inwad and inward iridodonesis is marked. The slit lamp examination of the zonular fiber is very attractive, In the left eye, dislocation is more severe than the other, and the zonular fiber are more elongated. The fibers are seen very clearly, Just like fine whitish silk contrast to its black background. At the 5 o'clock Position pupil margin in th left eye, one of them was revered and distorted. No significant fundus signs were seen. His parents and four brothers all have Normal visions and skeletons Normal cardiovascular system, even x-raypicture, balium in in esophagus, and normal E.C.G. picture. The second sase; 5 year old girl, Height 120 cm, weight 20.6 kg, typical skeletor, hands and feet. Vision both 0.2, 0.2 and 0.3 with -sph.9.0 D. Left eye; typical dislocated lens, upward and outward. iridodonesis is also found, no significant fundus picture. Normal cardiovascular system, even x-ray picture, balium in esophagus, and normal E.C.G. picture. Father; normal vision and skeleton. mother; typical skeleton, hands and feet, but normal vision, said her grandmother also had delicate bony structure and very poor vision, died known causes. The literature is briefly reviewed and the Post- operative complication esp. detachment of retina, emphasized.

To define the effectiveness of surgical management of the mallet finger deformity due to extensor tendon injury in children, we analyzed 9 patients who had operative treatment of mallet finger deformity in children from Jan. 1994 to Mar. 1997. The types of tendon injury in this series were as follows: 7 cases with tendon laceration, 1 case with crushing injury and 1 case with unknown injury The average period of follow up were ranged 2 years and 1 month. The clinical results were evaluated hy Kanies seale12) and Crawford scale5). An excellent result was obtained in 4 cases(44%), a good result in 5 cases(56%) according to Crawford scale and excellnt result in 9 cases(I00%) in Kanies scale, consecutively. Meticulous surgical repair of the lacerated tendon provided good result.

Reconstruction of the auricle is one of the most fastidious fields in plastic and reconstructive facial surgery, because the ear is made up of complex cartilage framework arid its thin skin envelope. Insertion of carved rib cartilage is the most popular method for framework fabrication. But it has some disadvantages such as donor site morbidity, lesser flexibility of rib cartilage, difficulty in carving structure and distortion of cartilage after calving. Furthermore surgeon's talent and sufficient practice are necessary for a satisfactory result. So we introduced the concept of perichondral graft to improve the framework fabrication. In 1972 Skoog and associates reported that free perichondral grafts could be used to produce new cartilage. And several other reports supported the chondrogenesis of free perichondral graft. We molded the human ear using silicone rubbed impression material. And the eat mold was wrapped up in perichodrium of rabbit ear and placed in a subcutaneous pocket in formes of graft and flap. Six and eight weeks later, rabbits were sacrified and the newly formed cartilage framework was harvested. Grossly it showed the same appearance as the human eat and elastic property of normal cartilage. In histologic examination, it showed mature structure of normal cartilage; large lacunae containing spherical chondrocytes surrounded by well defined capsule.

Various anatomical defects have been described in the surviving co-twin who had stillborn, macerated monozygotic co-twin with disseminated intravascular coagulation. The suggested mechanism was the transfer of emboli or thromboplastic materials of dead fetus to co-twin through placental vascular anastomoses. Multicystic encephalomalacia is the condition defined anatomically by the presence of multiple cavities in the great part of both cerebral hemispheres. The most common pathogenesis is circulatory disturbance caused by neonatal asphyxia during the perinatal period. We experienced two cases of monozygotic twin with deceased co-twin at 26 weeks, 33 weeks of gestation and confirmed the diffuse multicystic encephalomalacia by cranial ultrasonography and MRI in a surviving co-twin. Only one patient has been followed who showed spastic cerebral palsy and severe mental retardation. We report two cases of multicystic encephalomalacia in a surviring co-twin with a intrauterine fetal death and its related literatures.

BACKGROUND: Thromboembolism is the major complication in patients with the insertion of cardiac prosthetic valves. The purpose of this study is evaluate the risk factors about the formation of left atrial thrombi after cardiac valve replacement. METHOD: Transesophageal(TEE) and transthoracic echocardiography(TTE) were done to evaluate postoperative cardiac condition in 98 patients with cardiac prosthetic valves from Jan. 1991 to Oct 1991. Several clinical and echocardiographic parameters were analyzied to evaluate the relationship with the formation of left atrial thrombi. RESULT: In univariate analysis, important factors related to the formation of left atrial thrombi are type of operation (p=0.027), postoperative left ventricular function(p=0.003), preoperative(p=0.037) and postoperative systolic ventricular size(p=0.024). However, in multivariate analysis postoperative left ventricular size(p=0.017), presence of previous thrombi(p=0.014), preoperative left atrial size(p=0.014) and postoperative left atrial size(p=0.014) are significant factors. CONCLUSION: Patients with high risk and low risk for the formation of left atrial thrombi after valve replacement can be identified by readily available clinical and echocardiographic variables.

One hundred eighty infants with oxygen therapy who were under 2,500gm birth weight or under 37 weeks of gestational age, were examined between January 1990 and November 1992. We performed clnical analysis and results were as follows. 1) Fifty six infants (31.1%) were diagnosed as retinopathy of prematurity. 2) The first examination was performed at 2.5 weeks of life on average, and the retinopathy of prematurity was diagnosed at 3.8 weeks on average. 3) The incidence of retinopathy of prematurity was highly associated with low birth weight (< or =1,890 gm), low gestational age ( < or =33.1 weeks), and high oxygen concentration with long duration (FiO2> or =0.4 over 1 week)(P<0.005). 4) Other associated risk factors were idiopathic respiratory distress syndrome, anemia, neonatal hypoxia and sepsis.
