A case of distal aortopulmonary septal defect associated with aortic origin of right pulmonary ar- tery, patent ductus arteriosus and hypoplasia of aortic isthmus in a 50-day-old female infant is presented. Ligation of patent ductus arteriosus, resection and end-to-end anastomosis of hypoplasia of aortic isthmus, implantation of rlght pulmonary artery to main pulmonary artery and autologous peri- cardial patch repair of aortopulmonary septal defect were performed under cardiopulmonary bypass as one-stage approach. Deep hypothermic total circulatory arrest was applied during repair of hypoplasia of aortic isthmus. The p stoperative course was uneventful.

Regional odontodysplasia(ROD) is relatively rare localized developmental anomaly of tooth formation in which hard tissue is affected. The maxilla is typically affected than the mandible, and especially the maxillary left quadrant is the most commonly involved. Females are affected twice as often as males, and there is no association with race. Its etiology remains undetermined, but local circulatory disorders, somatic mutations, virus infections, local trauma, hyperpyrexia, irradiation, metabolic disturbances, and hereditary transmission are considered as possible etiologic factors. The affected teeth are likely to be small, hypoplastic, brown, and grooved. Eruption failure or delay is frequently seen as well as abscess or fistulae formation in absence of caries. Radiographically, there is a lack of contrast between the enamel and dentin, both of which are less radiopaque than unaffected counterparts. Moreover, enamel and dentin layers are thin, giving the teeth a “ghost-like appearance”. The pulp chambers and canals are large, the roots seem like to be short and indistinct. A 2-year-3-month old boy came to the department of pediatric dentistry, Yonsei University, with the chief complaint of delayed eruption and abnormal tooth shape on the lower left quadrant. He was diagnosed as regional odontodysplasia based on the clinical and radiographic findings.

Syndrome of 4q deletion is characterized by an abnormal shape of the skull, craniofacial dysmorphism, cardiovascular malformations, genitourinary defects, limb and digital anomalies, and developmental delay. We experienced a case of 4q interstitial deletion in a 2 day-old female neonate who showed short extremities, partial agenesis of corpus callosum and congenital heart defects. We report the case with a brief review of the literature.

Purpose : The purpose of this study was to assess the natural history and perinatal outcomes of twin gestations according to chorionicity. Methods : We retrospectively reviewed the medical records of 99 monochorionic (MC) and 206 dichorionic (DC) twin gestations delivered at Il Sin Christian Hospital in Busan between January 2002 and December 2007. The incidences of twin-to-twin transfusion syndrome (TTS) and selective intrauterine growth restriction (sIUGR), as well as perinatal morbidity and mortality, were evaluated. Results : MC twins had a lower gestational age (35.7 vs. 36.6 weeks, P=0.03) at birth and a higher incidence of intrauterine fetal loss (10% vs. 1.5%, P<0.001) than DC twins. The incidence of intrauterine fetal loss was higher in MC sIUGR than in DC sIUGR (19% vs. 2.5%, P=0.025) twins. The number of admissions to the neonatal intensive care unit (NICU; 31% vs. 16%, P=0.042), and the incidence of periventricular leukomalacia (7% vs. 0%, P=0.031), and respiratory distress syndrome with surfactant treatment (27% vs. 11%, P=0.049) were higher in MC than DC twins. The incidences of sIUGR and TTS were 21 and 9% among the MC twins. The incidences of intrauterine fetal loss were higher in MC twins with TTS [6 of 9 (67%)] or sIUGR [4 of 21 (19%)] than uncomplicated MC twins (P<0.001). The frequency of admission to the NICU (P=0.001), the length of hospital stay (P=0.033), the prevalence of periventricular leukomalacia (P=0.011), and intraventricular hemorrhage (P=0.007) were also higher in MC with TTS or sIUGR than in uncomplicated MC twins. Conclusion : The incidence of neonatal complications was higher in MC twins, especially those gestations complicated by TTS or sIUGR.

Scimitar syndrome (SS) is a rare congenital anomaly characterized by hypoplasia of the right lung and partially anomalous pulmonary venous drainage to the inferior vena cava. The term scimitar derives from the shadow created by the anomalous pulmonary vein on chest X-ray that closely resembles that of a curved Turkish sword. It rarely presents as an isolated abnormality. Various cardiac and non-cardiac anomalies have been association with SS, such as right lung hypoplasia, dextroposition of the heart, hypoplasia of the right pulmonary artery, systemic arterial blood supply to the right lower lung from the infra-diaphragmatic aorta, and a secundum type of atrial septal defect. However, an imperforate anus has not been reported previously in association with SS. We describe the first case of infantile scimitar syndrome accompanied with an imperforate anus in a newborn who presented with tachypnea and right pulmonary atelectasis.

취장 외분비 기능 부전은 임상적으로 영양결핍, 발육부전, 지방변동을 유발하나 이의 치료로는 결려된 소화효소 보충 등 보존적 요법만 시행될 뿐 근본적인 치료법은 없는 실정이다. 지난해 과제는 합성 단백분해 억제물질인 Camostat이 취장의 비대와 중식을 일으키며 또한 단백분해 효소분비를 증가시킴을 보고한 바 있다. 이를 토대로 최근 보고된 실험적 취장 외분비기능 부전 모델을 이용하여 camostat의 효과를 검색하고자 하였으며 아울러 이를 CCK효과와 비교하였다. 실험동물로는 몸무게 200 g 안팎의 수컷 Sprague-Dawley계 흰쥐를 사용하였으며 취장기능 부전은 oleic acid (25 $\mu$/100 g bw)를 취관내 주입하여 유발하였다. Camostat은 200 mg/kg씩 위내 투여(i.g.)하였으며 CCK(CCK-8)는 5 $\mu\textrm{g}$/kg씩 하루 2회 피하주사하였고 투여기간은 각각 3, 7, 14 일간으로 하였다. 각 약물 투여 후 취장 외분비 기능과 조직학적 검색을 실시하여 다음과 같온 결과를 얻었다. 1. Oleic acid의 취관내 주입으로 흰쥐의 취장 무게, 조직내 효소단백 함량 및 효소분비량이 현저히 감소되었고 조직학적으로 심한 위축과 섬유화를 관찰할 수 있었으며 이는 주입 후 기간이 지남에 따라 계속 진행하였다. 2. 취장기능 부전 유발 흰쥐에서 camostat 처치로 조직내 효소단백 함량 및 효소분비가 증가 되었으며 이는 14일간 처치군에서 뚜렷하였다. 3. 취장 기능부전 유발 횐쥐에서 camostat 처치는 조직학적으로 기능적인 외분비 조직이 유지되었으며 이는 3일군에서 특히 뚜fut하였다. 4. 취장기능부전 유발 횐쥐에서 CCK 처치효과는 camostat 처치효과와 비슷하였다. 이상의 결과로 보아 oleic acid 주입은 취장기능부전 연구에 유용한 실험모델로 생각되며 합성 단백 분해 효소 억제제인 Camostat은 취장외분비 기능 부전의 진행을 억제하고 어느정도 그 기능을 호전시킬 수 있으며 이는 CCK유리에 기인한다고 생각한다.

브로일러 사육과정에서 3주 이후에 흔히 발생하는 다리, 관절, 발톱 등의 이상으로 압사 또는 발육부전이 나타나 외모가 흉스러운 상품으로 인하여 경제적 손실과 사료요구율을 저하시키는 예가 종종 발생한다. 이때 농장에서는 급여사료의 미량성분 부족이나 병아리의 불량추에서 발생하는 것으로만 생각할 수 있으나 그 요인은 여러 가지가 있을 수 있어 최근 외국에서의 문헌에 실질적인 발생요인을 기술하였기에 인용, 기고하여 각 농장에서 피해를 최소화할 수 있도록 조치하는데 도움이 되었으면 한다.
