Purpose: To report our experience of gastrointestinal operations performed in neonates including low birth weight infants and to evaluate their clinical characteristics. Methods: We retrospectively reviewed the medical records of patients who underwent neonatal gastrointestinal surgery or had necrotizing enterocolitis (NEC) or inguinal hernia from January 2008 to December 2010 at Pusan National University School of Medicine. Results: The main disease was anorectal malformation and male patients were dominant. Twenty four patients (19.2%) had one or more associated anomalies including hydronephrosis and congenital heart disease. Eighteen patients (43.9%) of anorectal malformation had other anomalies. Seventy six percent of NEC cases were very low birth weight infants. Concerning mean days of full enteral feeding after operation, NEC patients needed 30.8 days, which was the longest period. Overall mortality of operation (except NEC and inguinal hernia operation) was 1.6%. The mortality of NEC with surgical treatment was 18.8%. The direct bilirubin in the operation group was significant higher than in the non-operation group in NEC patients. Conclusion: The morbidity and mortality after neonatal gastrointestinal surgery were excellent. The direct bilirubin in the operation group was significant higher than in the non-operation group in NEC.

A 4-year old Korean-native cow of third parturition delivered an deformed calf with congenital anasarca and hypoplasia of the extremity at Muan County in Chonnam Province. At parturition, the dam showed amniotic fluid approximately two times more than that at the normal and also occurred severe dystocia. The anomaly died before parturition was 82 cm long and weighed 25 kg. It was difficult to recognize the neck and face of the anomaly due to severe edema and the stretched tongue through mouth was found. The shape of the extremity was recognizable and the systemic hypoplasia of the body with marked edema was found. At necropsy, there was a large amount of serous fluid both in pleural and peritoneal cavity. Also the fluid was contained some of yellowish granular materials and diffusely was fulfilled in all subcutaneous tissue. There was a partial opening in diaphragm which was resulted in the protrusion of approximately half of liver toward peritoneal cavity. There were two kidneys (15${\times}$21 and 13${\times}$18 cm) on the left which were enlarged and relatively larger than the right one (13${\times}$9 cm). In addition, there were found slight to moderate hepatomegaly and splenomegaly with slight congestion, and diffuse edema of intestinal serosa. Lung (32${\times}$49 mm) with marked hypoplasia was smaller than the size of heart (56${\times}$45mm). Serological test to the dam showed relatively high antibody titer (＞64) to Akabane virus which might be involved in the outbreak of the deformed Korean-native calf as one of many causative agents.

This study used the probit analysis to evaluate the toxicity of three chemicals - benomyl (Germicide), carbofuran (insecticide), and thiobencarb (herbicide) - with the FETAX (Frog Embryo Teratogenesis Assay-Xenopus) protocol using the incubated embryos of tree frog, Hyla japonica. The results showed that the larval body length decreased while the mortality and malformation rates increased as the concentrations of benomyl, carbofuran, and thiobencarb increased. The teratogenic concentration ($EC_{50}$) of benomyl, carbofuran, and thiobencarb were 1.00, 0.58, 4.75 mg/L, respectively, indicating that the malformation of larvae was the most sensitive to carbofuran. The embryo lethal concentration ($LC_{50}$) was 7.04, 28.71, and 16.12mg/L, respectively, indicating that benomyl showed the lowest embryo lethal concentration. The teratogenic index (TI) was 7.04 in Benomyl, 49.50 in Carbofuran, and 3.39 in Thiobencarb, indicating that the TI values were above 1.5, which is the criterion of teratogenicity, for all three chemicals. All three pesticides examined by this study were considered to be the most teratogenic substances, and the carbofuran was the most potent teratogen.

Cervicovaginal venous malformations are extremely rare. Sclerotherapy is proven to be effective for superficial venous malformations but not for venous malformations in the lower genital tract of female. A 52-year-old female presented with intermittent vaginal bleeding. The amount of vaginal bleeding gradually increased over 3 months. Contrast-enhanced pelvis CT showed several phleboliths and dilated vessels, but pelvic angiography showed no early draining veins, nidus, or feeding artery. We performed transvaginal direct puncture and ethanol sclerotherapy rather than surgical treatment because she wanted to preserve the uterus. After four sessions of sclerotherapy, she had significantly decreased vaginal bleeding without complications. Here, we report the first case of cervicovaginal venous malformations successfully treated with transvaginal direct puncture and ethanol sclerotherapy.

Ebstein's anomaly is attached to the right ventricle with the tricuspid leaf attached to the lower right ventricle without any attachment to the tricuspid annulus. Most patients in their 20s are alive. Patients older than 25 years of age are similar in the incidence of heart failure and sudden death, and survive approximately 70% from 2 years, and 50% from 3 years, from 5% to over 50 years of age. Through this example, Ebstein's anomaly exists in various forms. A 22 year old case with WPW syndrome and those who survived to 77 years of age are reported. The normal heart structure in the apical four-chamber view should be observed on similar lines, even though the tricuspid annulus is slightly lower than the mitral annulus. If not, there will be some doubt regarding this anomaly. Furthermore, echocardiography plays an important role in the diagnosis and prognosis of congenital heart disease.

The clinical features of ring chromosome 13 include mental and growth retardation, CNS anomalies, facial dysmorphism, cardiac defects, genital malformations, limb anomalies, skeletal deformities and anal malformations. Although many cases of ring chromosome 13 have been reported worldwide, only 6 cases have been reported in Korea, and the latter cases were not mosaic but pure ring chromosome 13. Here we report a case with mosaic ring chromosome 13. The baby boy was born at 37 weeks of gestation by induced vaginal delivery due to intrauterine growth restriction (IUGR). He was the second baby of a 28-year-old hepatitis B carrier mother and a 32-year-old father. There was no family history of chromosomal anomalies. The baby was a symmetric IUGR with a birth weight of 1,860 g, length of 44.8 cm, and head circumference of 29.4 cm. The physical examination revealed microcephaly, trigonocephaly, flat occiput, large ears, short neck and dysmorphic facial features, including microophthalmia, hypertelorism, antimongoloid slanting palpebral fissures, a flat nasal bridge, and micrognathia. The karyotype of this patient performed by peripheral blood lymphocytes was 46,XY,r(13)(p13q34)/45,XY,-13/46,XY,dic r(13;13)(p13q34;p13q34). The baby showed failure to thrive, hypotonia, and developmental delay. We report the first case of mosaic ring chromosome 13 in a male baby in Korea and compare this case with other Korean cases of non-mosaic ring chromosome 13.
