Congenital cystic adenomatoid malformation[CCAM] is a rare disease that cause respiratory distress in the newborn and infants, but is one of the two causes along with lobar emphysema. This malformation has the pathologic characteristics which can be differentiated from other forms of diffuse cystic disease, i.e. CCAM is marked proliferation of the terminal bronchioles and that can enlarge rapidly by air trapping in cystic areas. The CCAM has a clinical importance because of rapid worsening respiratory distress, with tachypnea, subcostal retraction and cyanosis. This is a strict surgical condition and after operation[lobar, segmental resection or pneumonectomy] the symptoms relieved obviously. We experienced 6 cases of CCAM from July, 1980 to September, 1987 at the Department of Cardiovascular and Thoracic Surgery, Severance Hospital, College of Medicine, Yonsei University. The male patients were two and female patients were four. The age distribution was from premature to 10 year old. One of them was 27 weeks gestational premature female who was borne dead. The other 5 patients were performed on thoractomy[1 case pneumonectomy and 5 cases lobectomy]. The postoperative courses were good and no complications were seen.

The incidence of small for gestational age (SGA) births is frequent, accounting for 2.3% to 8% of all live births. Several childhood and adult diseases are related to early postnatal growth and birth size, and 10% of children born SGA may have a short stature throughout postnatal life. Additionally, they may have abnormal growth hormone (GH)-insulin like growth factor axis, HPA axis, and gonadal function. Permanent changes are detrimental in an environment of nutritional abundance, and predispose SGA children to an array of diseases in adolescence and adulthood. Such changes may also cause premature pubarche, adrenarche, and precocious puberty. The varying results from clinical studies necessitate more prospective case control studies. Reproductive tract abnormalities and reproductive dysfunction are related to SGA births. GH treatment is required for SGA infants who do not experience catch-up growth.

식도천공은 신생아에서 드문 질환이다. 그러나 영양관 삽관으로 인한 의인성 식도천공은 미숙아에서는 특히 드물지 않게 나타난다. 의인성 식도천공은 기흉같은 심한 합병증을 유발하며 사망을 일으킬 수 있다. 일반적으로 식도천공의 결과로 기흉이 발생하는 것으로 알려져있다. 반면에, 저자들은 기흉이 먼저 병발하고 이 후 의인성으로 발생한 식도천공을 경험하였다. 증례의 식도천공은 환아에게 기흉이 발생한 채로 영양관을 삽관하여 야기되었다. 기흉이 있는 상태에서 영양관 삽관을 고려할 때는 더 심사숙고 하여야 할 것이다.

Purpose: This study aimed to investigate the relative weight gain at 2-week intervals up to 6 weeks after birth to predict retinopathy of prematurity (ROP) requiring treatment among very low birth weight infants. Methods: A total of 211 preterm infants with birth weights <1,500 g and gestational age <32 weeks were retrospectively reviewed. The main outcome was the development of ROP requiring treatment. Body weight measurements were recorded daily. Relative weight gains (g/kg/day) were calculated at the second, fourth, and sixth week after birth. Results: Of the 211 infants, 89 developed ROP, of which 41 spontaneously regressed and 48 with early treatment of ROP type I required laser treatment. The relative weight gain at 2, 4, and 6 weeks postnatal age was significantly lower in infants with ROP requiring treatment than in infants without ROP or those with spontaneous regression (P<0.001, P=0.005, and P=0.004, respectively). On logistic regression, poor relative weight gain in the first 2 weeks was found to be related to ROP requiring treatment (adjusted odds ratio, 0.809; 95% confidence interval, 0.695-0.941; P=0.006). Relative weight gain at 2 weeks postnatal age was significantly lower in infants with ROP requiring treatment compared to that in ROP requiring no treatment (P=0.012). Conclusion: Poor postnatal weight gain in the first 2 weeks of life is an important and independent risk factor for ROP requiring treatment. Postnatal weight gain can predict the development of severe ROP requiring treatment.

Purpose: In this study, we aimed to review the clinical presentation of preterm infants with gastrointestinal perforations and compare the clinical features of gastric perforation with other intestinal perforations. Methods: The medical records of preterm neonates with pneumoperitoneum, admitted to the neonatal intensive care unit (NICU) between January 1994 and December 2013, were retrospectively reviewed. Results: Twenty-one preterm infants underwent exploratory laparotomy to investigate the cause of the pneumoperitoneum. The sample consisted of five patients (23.8%) with gastric perforation and 16 patients (76.2%) with intestinal perforation. No statistical differences were found in the birth history and other perinatal factors between the two groups. Underlying necrotizing enterocolitis, bilious vomiting, and paralytic ileus preceding the perforation were statistically more common in the intestinal perforation group. All preterm infants with gastric perforation survived to discharge; however, six preterm infants with intestinal perforation expired during treatment in the NICU. In the gastric perforation group, sudden pneumoperitoneum was the most common finding, and the mean age at diagnosis was $4.4{\pm}1.7days$ of life. The location and size of the perforations varied, and simple closure or partial gastrectomy was performed. Conclusion: Patients with gastric perforation did not have a common clinical finding preceding the perforation diagnosis. Although mortality in previous studies was high, all patients survived to discharge in the present study. When a preterm infant aged less than one week presents with sudden abdominal distension and pneumoperitoneum, gastric perforation should first be excluded. Prompt exploratory laparotomy will increase the survival rates of these infants.

The present analysis was undertaken to find out the relationships between birth weight & Apgar Score of newborn infant & maternal factors. The medical records of 1436 newborn infants who had been at the Korea University III Seoul from January. 1.1984. to December. 31. 1985, were examined. Measurements include weight and Apgar Score. As the possible factors influencing the birth weight & Apgar Score of newborn infant, 9 variables such as : mother's age, frequency ·of pregnancy, frequency of fullterm delivery, frequency. of premature, frequency of abortion, mother's hemoglobin level, complications during pregnancy gestational period and infant sex at birth were selected among the items recorded in the medical records of newborn infants and their mothers. The weight & Apgar Score of newborn infants were compared separately by sex with group percent of those variables. The results were summarized as follows: 1. All of those factors chosen are supposed to be influencing upon the birth weight and Apgar Score examined at birth indirectly through inducing early termination of pregnancy. 2. The most influencing variable of birth weight of newborn infants was gestation period. The most influencing variable of Apgar Score of infant newborn was gestation period. 3. The relationships of those influencing factors are more clear on the birth weights of newborn than on the Apgar Score. 4. More then half of low birth weight infants are turned out to be physiologically normal through the evaluation by Apgar Scoring. Conclusively, All of those factors chosen are supposed to be influencing upon the birth weight and apgar score examined at birth indirectly through inducing early termination of pregnancy.

Purpose: To compare between sodium acetate (SA) and sodium chloride (SC) in parenteral nutrition (PN) with associated metabolic acidosis and neonatal morbidities in preterm infants. Methods: Preterm infants below 33 weeks gestational age, and with a birth weight under 1,301 g were enrolled and further stratified into two groups: i) <1,000 g, or ii) ≥1,000 g in birth weight. The subjects were randomized to receive PN containing SA or SC within the first day of life. The results of routine blood investigations for the first 6 days of PN were collated, and the neonatal outcomes were recorded upon discharge or demise. Results: Fifty-two infants entered the study, with 26 in each group: 29 infants had extremely low birth weight (ELBW). There were no significant differences in birth weight, gestation, sex, exposure to chorioamnionitis and antenatal steroids, surfactant doses and duration of mechanical ventilation between groups. The SA group had significantly higher mean pH and base excess (BE) from days 4 to 6 than the SC (mean pH, 7.36 vs. 7.34; mean BE -1.6 vs. -3.5 [p<0.01]), with a two-fold increase in the mean BE among ELBW infants. Significantly fewer on SA required additional bicarbonate (n=4 vs. 13, p=0.01). The rate of bronchopulmonary dysplasia (BPD) was approximately four-fold lower in SA than SC (n=3 vs. 11, p<0.01). No significant differences were observed in necrotizing enterocolitis, patent ductus arteriosus, retinopathy of prematurity, cholestatic jaundice, and mortality between groups. Conclusion: The use of SA in PN was associated with reduced metabolic acidosis and fewer BPD.

목 적 : 미숙아에서 흔히 발생되는 뇌실내 출혈의 낭성병변은 출혈이 흡수되는 과정에서 생기는 것으로 출혈 후 수일에서 수주내 나타나는 것으로 알려져 있다. 본 연구는 출생 후 5일 이내에 실시한 뇌초음파 소견상 이미 낭성병변을 동반한 뇌실내 출혈을 지닌 환아들을 태아기 뇌실내 출혈을 보인 환아로 가정하고 이들의 특징적인 임상소견과 신경학적 예후 및 산전 위험인자를 알아보고자 하였다. 방 법 : 대상군으로는 1999년 1월부터 2003년 6월까지 3년 6개월간 본원 신생아 집중치료실에 입원한 환아 중 생후 5일 이내에 실시한 뇌초음파 검사상 낭성병변을 동반한 뇌실내 출혈을 지닌 환아와 대조군으로는 같은 기간 중 입원된 뇌실내 출혈이 없었던 환아를 대상으로 이들의 의무기록과 산모의 의무기록을 후향적 조사하였다. 결 과 : 연구 기간동안 뇌초음파를 실시한 총 1,024명의 환아 중에 309명이 뇌실내 출혈을 보였고, 이중 첫 뇌초음파상 낭성병변을 동반한 뇌실내 출혈을 보여 태아기 뇌실내 출혈의 조건을 만족하는 환아는 49명이었다. 이들 환아들의 출생체중은 대부분 1,501 g 이상이었고, 재태연령 역시 34주 이상이었으며, III등급 뇌실내 출혈을 동반한 1명을 제외한 48명의 환아가 I등급의 뇌실내 출혈과 동반한 낭성병변을 보였다. 2명(4.4%)만이 이후 실시한 뇌초음파 검사상 낭성병변의 크기가 증가하였고, 11명(24.4%)은 평균 34일만에 사라졌다. 태아기 뇌실내 출혈과 연관된 산전 인자로는 산모의 나이가 적을수록, 초산일수록, 산전스테로이드를 투여 받지 못하였을 때 의미있게 태아기 뇌실내출혈이 증가하였고, 신생아 인자로는 신생아 호흡곤란 증후군과 동반한 경우 유의하게 증가하였다. 여러 인자들에 대한 다변수로지스틱 회귀분석 결과 신생아 호흡곤란 증후군을 보인 경우와 태반 조직검사상 경색소견을 보인 경우가 의의가 있었으며 생후 18개월경까지의 신경발달학적 예후에 있어서는 두 군간 별다른 차이를 보이지 않았다. 결 론 : 미숙아의 태아기 뇌실내 출혈의 빈도는 15.9%로서 전체 뇌실내 출혈 중 많은 부분을 차지하고 있었으나 대부분 I등급의 경미한 출혈로서 짧은 기간동안의 추적관찰상 신경발달학적 예후에 영향을 미치는 중요한 인자는 아니라고 사료된다.
