PURPOSE: To investigate the clinical results and safety of the acellular dermal allograft (SureDerm(R), Hans Biomed co., Korea) as a new spacer graft in anophthalmic socket contracture. METHODS: We grafted SureDerm(R) as the replacing spacer in 8 patients for the treatment of anophthalmic socket contracture. Under local anesthesia, SureDerm(R) was sutured at the levator aponeurosis and upper margin of the tarsus using 6-0 Vicryl in the upper lid. In the lower lid, SureDerm(R) was sutured at the tarsal conjunctiva and lower margin of the incised conjunctiva. The patients were followed-up individually for 6 to 15 months. RESULTS Surgical results in all 8 eyelids (6 lower lids, 2 upper lids) were satisfactory. The grafted SureDerm(R) survived in all patients with little contracture. There were no other complications such as infection, rejection, or exposure. CONCLUSIONS: We consider SureDerm(R) a good replacing spacer material for the treatment of anophthalmic socket contracture.

This is a report of a successful, rapid two-stage arterial switch operation in an infant with dextrotransposition of great arteries with an intact ventricular septum beyond the appropriate time for arterial switch operation. A 4-month-old female infant was admitted due to severe cyanosis, respiratory insufficiency, and frequent diarrhea secondary to ischemic colitis. Echocardiographic examination presented marked leftward deviation of the interventricular septum, and left and right ventricular pressures as measured by cardiac catheterization were 40/4 mm Hg and 85/2 mm Hg, respectively. Fifteen days after a preparatory operation (pulmonary artery band with modified right Blalock-Taussig shunt), left ventricular-right ventricular systolic pressure ratio increased to 105/90. Arterial switch operation associated with the division of the right Blalock-Taussig shunt and the removal of pulmonary artery band was performed. After the operation, the infant showed normal cardiac function with no postoperative complication.

We studied whether the structure and size of nasal cavity around osteotomy site had an influence on the success rate of endoscopic endonasal dacryocystorhinostomy [DCR]. Endoscopic endonasal DCR was performed on 80 eyes of 72 patients who had obstruction of nasolacrimal system.We graded nasal cavity around osteotomy site according to the diameter of drill which could pass[grade I:7 mmdrill can pass, grade II:5 mmdrill can pass, grade III:3 mmdrill can pass, grade IV:3 mmdrill cannot pass].The primary success rate is 70%[56 eyes] and final success rate is 81.3%[65 eyes]after secondary operation was perfomed on 14 eyes of 24 failed eyes in primary operation.Primary success rate was 78.8%[41/52 eyes]and 53.6%[15/28 eyes]in grade I-II and grade III-IV, respectively.Final success rate was 86.5%[45/52 eyes]and 71.4%[20/28 eyes]in grade I-II and grade III-IV, respectively.The difference of success rates according to nasal cavity size is stastically significant[P<0.05] and the relation of nasal septum deviation to small nasal cavity is stastically significant[P<0.05].We found canalicular obstruciton in 5 of 14 eyes during secondary operation which was not found in primary speration, and it was suspected to have been caused by mechanical trauma to canalicular system during operation.

The major causes of small bowel obstruction are postoperative adhesion, hernia, intussusception and malignancies. However, in cases of uncommon causes of small bowel obstruction, surgeons are in a dilemma because the preoperative diagnosis and making a decision to operate are frequently difficult and delayed. Phytobezoars are unusual cause of small bowel obstruction. They are mostly due to ingestion of stringent immature fruits following gastric surgery. They are usually formed in stomach and do not migrate to the other intestinal tract, but can lead to the serious complication of acute small bowel obstruction. We are reporting a case of acute small bowel obstruction due to phytobezoar about 2x2x3 cm3 size in a 90 year old female.

OBJECTIVES: The objective of this study is to analyze 1,068 cases of prenatal genetic amniocentesis and to compare the results with reported studies. METHOD: We analyzed 1,068 cases of midtrimester prenatal genetic amniocenteses from September 1994 to February 1999, and investigated the fetal chromosomal abnormality, obstetric outcomes and complications by the indications of genetic amniocentesis and prophylactic antibiotic use at the Department of Obstetrics and Gynecology, Ajou University School of Medicine. RESULTS: Abnormal maternal serum markers were the most common indication of amniocentesis (57.7%) and the most common age distribution was 25-29 years (39.2%). One case of early amniocentesis (14 gestational weeks) was performed. The overall incidence of chromosomal aberration was 5.2% (56/1,068), of which there were 28 cases (50.0%; 28/56) of numerical aberrations and 28 cases (50.0%; 28/56) of structural aberrations. There were 50 cases (4.7%) of autosomal chromosomal aberrations and 6 cases (0.6%) of sex chromosomal aberrations. The pregnancy outcome was full-term delivery in 86.5%, preterm delivery in 7.6%, termination of pregnancy in 4.0%. There were no cases of serious complications including fetal death except for a case of self-limited amniotic fluid leakage(high leakage) in which the pregnancy was maintained. There were no significant differences between prophylactic antibiotics user group and non-user group in obstetric complications and outcomes. CONCLUSION: We could confirm that the trend in the indication of genetic amniocentesis had changed from advanced maternal age(35 year-old) toward abnormal maternal serum marker(triple test), and we recognized the importance of genetic amniocentesis according to the various antenatal screening tests of maternal serum marker, antenatal ultrasound, past history of fetal anomaly or family history of fetal chromosomal anomaly in the younger age groups(< 35 year-old) that are involved in more than half of the chromosomal anomaly. Further study will be needed to elucidate the efficacy of using prophylactic antibiotics in amniocentesis.

The Finnish type of Congenital Nephrotic Syndrome is characterized by large placenta, early manifestation, growth and developmental delay and resistance to treatment. Authors experienced a case of characteristic Finnish type of Congenital Nephrotic Syndrome in a girl, who was admitted to the Pediatric Department of KHUH at 2 1/1 months of age because of generalized edema and abdominal distension and died of pneumonia at 5 1/2 months of age. The diagnosis was made by birth history, clinical manifestation, laboratory findings and finally by the autopsy findings, Literatures are reviewed briefly.

We reviewed a policy of primary surgical closure of large ventricular septal defects in small infants. Sixty-three infants met criteria for inclusion in the study, and were divided into two groups based on age: group 1 infants aged less than 5 months(n = 31), and group 2 infants aged 5 months or more(n = 32). Both groups had similar variation in ventricular septal defect location(paramembranous versus muscular), and showed no significant difference in left to right shunt and in ratio of systemic and pulmonary vascualr resistance. Three early deaths(9.7%) occurred in group 1, but no death(0%) in group 2. The causes of death were preoperative cardiac arrest and cerebral injury followed by postoperative respiratory insufficiency in two patients, and preoperative tracheomalacia followed by laryngeal edema and respiratory arrest in one. Two patients in group 1 showed postoperative low cardiac output syndrome(6.5% in group 1 versus 0% in group 2). There was no late death during the follow-up period in both groups. No surviving patients had postoperative patch leakage, or required a second operation. These results indicate that primary surgical closure of large ventricular septal defects, if logical perioperative care is accompanied, can be safely performed in small infants aged less than 5 months with low postoperative mortality or morbidity rates.

Schwannomas rarely present as intraocular tumors and are often misdiagnosed as malignant melanoma. We describe a choroidal schwannoma confirmed by sclerouvectomy. A 30-year-old woman presented with a large nonpigmented intraocular mass of the choroid in the right eye and underwent surgical excision by sclerouvectomy. Histologically, the tumor was composed of a mixture of cellular solid components (Antoni A) and loose myxoid components (Antoni B). The tumor was eventually diagnosed as a schwannoma. Currently available ancillary studies are still of little value in definitively differentiating schwannomas from other choroidal tumors. In the case of atypical findings for a malignant melanoma, a benign neoplasm should be included in the differential diagnosis. This patient avoided enucleation by first having the mass excised. We are unaware of previous reports in which a choroidal schwannoma was diagnosed by surgical excision.
