Purpose: The present study assessed the role of an amino acid-based formula (AAF) in the growth of infants with cow's milk protein allergy (CMPA). Methods: Non-breastfed, term infants aged 0-6 months with symptoms suggestive of CMPA were recruited from 10 pediatric centers in China. After enrollment, infants were started on AAF for two weeks, followed by an open food challenge (OFC) with cow's milk-based formula (CMF). Infants with confirmed CMPA remained on AAF until 9 months of age, in conjunction with a cow's milk protein-free complementary diet. Body weight, length, and head circumference were measured at enrollment and 9 months of age. Measurements were converted to weight-for-age, length-for-age, and head circumference-for-age Z scores (WAZ, LAZ, HCAZ), based on the World Health Organization growth reference. Results: Of 254 infants (median age 16.1 weeks, 50.9% male), 218 (85.8%) were diagnosed with non-IgE-mediated CMPA, 33 (13.0%) tolerated CMF, and 3 (1.2%) did not complete the OFC. The mean WAZ decreased from 0.119 to -0.029 between birth and enrollment (p=0.067), with significant catch-up growth to 0.178 at 9 months of age (p=0.012) while being fed the AAF. There were no significant changes in LAZ (0.400 vs. 0.552; p=0.214) or HCAZ (-0.356 vs. -0.284; p=0.705) from the time of enrollment to age 9 months, suggesting normal linear and head growth velocity. Conclusion: The amino acid-based study formula, in conjunction with a cow's milk proteinfree complementary diet, supported normal growth till 9 months of age in a cohort of Chinese infants with challenge-confirmed non-IgE-mediated CMPA.

Although nursing researchers have performed studies on parent-child relationship actively since early 1980s in Korea, nothing hasn't been tried on the analysis of the contents of researches. We researchers tried examining the trend of researches by investigating treaties on mother-child relationship conducted from 1981 to 1994. The purpose of this study was to analyze the trend of research on the mother-child relationship and to suggest direction for future study. The total numbers of the studies were 27 cases, These studies were analyzed for 1) time of publication 2) research design 3)main concept 4)thesis for a degree or nondegree 5) measurement tool The finding of the analysis were as follows. 1) In the chronological situation, the research on mother-child relationship began to perform in 1981 in the country and had been made most for five years to 1986 with 14 treaties and has decreased since 1990. 2) In the research plan, there are 21 survey(the most) ,5 quasi experimental(before 1986), 1 qualitative. 3) In the subject, the researches on mother-child are the most, 22 and of them 17 treaties on normal infant,4 comparative research on high risk infant and normal infant,5 treaties on mother, 4) The conception of mother-child relationship was used as various conceptions such as affection, union, bonding in early research of 1980s, but it hasn't been used as union bonding but studied mostly as the conception of 'mother-child interaction'since 1986. 5) The measurement tool of research was used variously, the Cropley's tool was used in early 1980s, but Walker's MIPS, Barnard's NCAST were used mostly in 1990. 6) Mother-child interaction influence on mother's self-conception, stress, care and feeding of child, frequency of delivery, planned pregnancy and delivery and health condition of child, birth weight, fetal period, period of mother-child life. Aspects of mother-child interaction composed on visual contact, looking at each other, skinship and caress with finger and fingertip. The leading action of mother-child interaction was mostly uttering action. 7) I suggest that the program for professional education is necessary for the establishment of the aspects of mother-child interaction.

목 적:신생아 집중치료술이 발달함에 따라 미숙아 및 극소 저체중 출생아 등의 고위험 신생아의 생존율이 크게 향상되었다. 따라서 이러한 고위험 신생아의 생존율 향상과 더불어 생존 환아에서 발육 지연, 뇌성마비, 청력 저하 등 신경학적 발달 이상을 보이는 환아의 수도 증가하여 이들 환아들의 이상을 보다 조기에 발견하기 위해 추적 관찰의 필요성이 증대되고 있다. 저자들은 신생아 집중 치료실에서 치료 후 퇴원한 환아 중 위험한 주산기 인자들로 인하여 발달 이상의 위험도가 상대적으로 높아 고위험 신생아로 추적 관리를 받고 있는 환아에서 Bayley 발달 검사를 이용하여 발달 이상의 위험 인자를 확인하기 위하여 연구를 시행하였다. 방 법:2002년 1월부터 2005년 11월까지 인제대학교 의과대학 상계백병원 신생아 집중 치료실에 입원하였던 신생아 중에서 퇴원 후 외래에서 추적 관리하였던 환아 중 Bayley 발달 검사를 시행한 94례를 대상으로 하였다. 연구 대상은 32주 미만의 재태 연령, 극소 저체중 출생아, 5점 이하의 Apgar 점수, 뇌 초음파 및 자기 공명 검사상 뇌실 내 출혈 혹은 뇌실주위 백색질 연화증 등의 이상, 신생아 소생술을 시행한 경우, 신생아 경련 또는 선천성 감염 중 한 가지 이상의 요인이 있었던 환아이다. 대상 환아들의 발달 검사로 Bayley 발달 검사(Bayley Scales of Infant Development II)를 임상심리치료사가 시행하였고, MDI와 PDI를 분석에 이용하였다. 결 과:뇌 초음파 및 자기 공명 검사는 MDI, PDI와 각각 통계적인 연관성을 보였으며(P<0.05, P<0.001), 뇌실주위 백색질 연화증의 경우 MDI는 $70.10{\pm}28.68$, PDI는 $69.70{\pm}24.91$로 의미 있게 낮은 점수를 보였다. MDI보다 PDI가 뇌의 영상학적 검사 소견과 상관관계가 더 큰 것으로 나타났다. PDI는 1분 Apgar 점수 및 극소 저체중 출생아와도 유의한 상관관계가 있었다(P<0.05, P<0.05). Bayley 발달 검사 결과는 성별, 재태 연령, 신생아 소생술 여부, 신생아 경련과 유의한 연관성이 없었다. 결 론:신생아 집중 치료실에서 치료받은 고위험 신생아를 추적 관찰하며 Bayley 발달 검사를 시행하였을 때, 검사 결과에 독립적으로 영향을 미치는 위험 인자는 뇌의 영상학적 검사 소견, 1분 Apgar 점수 및 극소 저체중 출생아였다. 그 중 뇌의 영상학적 검사 소견상 이상이 있는 경우 발달 장애의 가능성이 가장 높고, 그 외의 위험 요인에 대해서도 주기적인 추적 관찰이 중요할 것으로 생각된다.

임신초기 모체의 엽산영양은 태아의 신경관 손상을 예방하는 측면에서는 물론이고 엽산 필요량이 증가하는 임신후기를 대비한다는 점에서도 중요하다. 그러므로 본 연구에서는 임신초기에 있는 151명의 임신부들을 대상으로, 이들이 식사를 통해 얼마의 엽산을 섭취하는지를 조사하고, 혈청과 적혈구의 엽산 농도와 혈장 호모시스테인 농도를 분석하여 엽산영양상태를 평가하고, 이들의 엽산영양상태에 영향을 미치는 인자들이 무엇인지 분석하고자 하였다. 본 연구대상자의 조사당시 임신기간은 9.1$\pm$2.3주이었으며, 초산부가 46%이었고 나머지는 경산부이었다. 에너지 및 엽산 섭취량은 각각 1559$\pm$589 ㎉/day 및 230.8$\pm$145.2 $\mu$g/day로 각 권장량의 72.5%및 46.2%로 낮았다 혈청과 적혈구의 엽산 농도는 각각 5.5$\pm$1.9 ng/mL 및 266.6$\pm$75.0 ng/mL으로, 연구 대상자의 7.8%가 혈청 엽산 수준이 3 ng/mL미만인 결핍상태에 해당하였고 60.3%는 경계역(3∼5.9 ng/mL)에 속하였으며, 적혈구 엽산 농도가 l57 ng/mL미만인 결핍상태에는 4.3%가 해 당하였다. 그러나 혈청 호모시스테인 농도는 정상범위이었다. 따라서 본 연구대상자의 엽산영양상태는 비교적 양호하다고 판정되었다. 혈청 엽산 농도에 영향을 끼칠 수 있는 유의한 인자는 건강상태점 수(+), 혈장 호모시스테인 농도(-), 연령 (-), 임신기간(-) 및 엽산 섭취량(+) 순으로 그 영향력이 높았고, 적혈구 엽산 농도의 영향인자는 교육수준(-), 혈장 호모시스테인 농도(-), 지난번 출산 영아의 출생시 신장(+),연령(-)및 에너지 섭취량(+)이었고, 혈장 호모시스테인 농도의 영향인자는 지난번 출산 영아의 출생시 신장(-), 경제수준(+),혈청 엽산 농도(-)와 임신전 체중(+)이었다. 이러한 결과는, 혈장이나 적혈구의 엽산 농도나 혈장 호모시스테인 농도를 분석하지 않고도, 임신초기에 있는 모체의 엽산영양상태를 개략적으로 판정하는데 있어 주관적으로 평가한 불량한 건강상태, 높은 교육수준 또는 경제수준, 지난번 출산에서 작은 체위의 영아를 출산한 경력, 고연령 또는 엽산이나 에너지섭취량 부족을 위험 인자로 활용할 수 있음을 시사한다. 아울러 임신기간이 진행되었을수록 엽산영양상태가 저하되었을 가능성이 있음도 나타내준다. 앞으로 임신초기 임신부의 엽산영양상태를 어떤 위험인자를 몇 가지나 가졌느냐에 따라 평가하는 연구결과가 나와야 이들 위험 인자의 실용성 을 확인할 수 있을 것이다. 그러나 우선 이들 위험 인자를 많이 지닌 임신부라면 임신초기부터 엽산 섭취량을 늘리거나 엽산보충제 섭취를 일찍 시작하는 등의 방법으로 엽산영양상태를 양호하게 유지하도록 하는 것이 바람직할 것이다.

Comprehensive review of the literature was conducted to determine 1) selected risk factors and its impact that affect pregnancy outcome such as smoking, alcohol consumption, and substance abuse 2) these factors can facilitate future strategies for health promotion and prevention for both pregnant women and fetus. Review of literature were extracted from searching MEDLINE(1966 - Oct. 2000). CINAHL (1982 - Oct. 2000) and the domestic literature. The following factors were identified: 1. The effects of risk behaviors on pregnancy. ${\cdot}$Maternal smoking was associated with the occurrence of premature or LBW delivery, fetal growth retardation, extremities defects, heart defects and sudden infant death syndrome. ${\cdot}$Maternal alcohol consumption was associated with spontaneous abortion, premature or LBW delivery, morphologic/neurologic problems, especially fetal alcohol syndrome. ${\cdot}$Heroin was associated with withdrawal after birth in which were born to heroine addicts for gestational age and lung maturation in animal studies. ${\cdot}$Cocaine was associated with spontaneous abortion, abruptio placenta and a poor response to environmental stimuli. ${\cdot}$So far, the effects of caffeine on pregnancy was controversial, but severe caffeine consumption was associated with premature or LBW delivery, spontaneous abortion, still birth and dystocia. 2. Intervention methods and its effects identified were as follows ${\cdot}$Conducted intervention for smoking, alcohol and drug consumption were single or combined. ${\cdot}$Intervention methods were counseling, phone contact, mailing, use of educational videotape, booklet, support person and alternatives such as nicotine patch. ${\cdot}$The interventions increased the rates of smoking cessation during pregnancy and awareness of the risk of drug consumption, and decreased amount of alcohol consumption. ${\cdot}$The intervention outcome found positive effect on birth weight and length. 3. Our recommendations were as follows ${\cdot}$The personal and social cognition should be enhanced through education and the mass media. ${\cdot}$It's necessary to educate and give information of preconceptional care, planned pregnancy and early prenatal care for optimal pregnancy outcome. ${\cdot}$It's necessary to develop comprehensive assessment tool which is reliable and valid on smoking, alcohol consumption and substance abuse to identify supportive or interventional program.

Objective : Owing to advances in critical care treatment, the overall survival rate of preterm infants born at a gestational age (GA) <32 weeks has consistently improved. However, the incidence of severe intraventricular hemorrhage (IVH) has persisted, and there are few reports on in-hospital morbidity and mortality. Therefore, the aim of the present study was to investigate trends surrounding in-hospital morbidity and mortality of preterm infants with severe IVH over a 14-year period. Methods : This single-center retrospective study included 620 infants born at a GA <32 weeks, admitted between January 2007 and December 2020. After applying exclusion criteria, 596 patients were included in this study. Infants were grouped based on the most severe IVH grade documented on brain ultrasonography during their admission, with grades 3 and 4 defined as severe. We compared in-hospital mortality and clinical outcomes of preterm infants with severe IVH for two time periods : 2007-2013 (phase I) and 2014-2020 (phase II). Baseline characteristics of infants who died and survived during hospitalization were analyzed. Results : A total of 54 infants (9.0%) were diagnosed with severe IVH over a 14-year period; overall in-hospital mortality rate was 29.6%. Late in-hospital mortality rate (>7 days after birth) for infants with severe IVH significantly improved over time, decreasing from 39.1% in phase I to 14.3% in phase II (p=0.043). A history of hypotension treated with vasoactive medication within 1 week after birth (adjusted odds ratio, 7.39; p=0.025) was found to be an independent risk factor for mortality. When comparing major morbidities of surviving infants, those in phase II were significantly more likely to have undergone surgery for necrotizing enterocolitis (NEC) (29.2% vs. 0.0%; p=0.027). Additionally, rates of late-onset sepsis (45.8% vs. 14.3%; p=0.049) and central nervous system infection (25.0% vs. 0.0%; p=0.049) were significantly higher in phase II survivors than in phase I survivors. Conclusion : In-hospital mortality in preterm infants with severe IVH decreased over the last decade, whereas major neonatal morbidities increased, particularly surgical NEC and sepsis. This study suggests the importance of multidisciplinary specialized medical and surgical neonatal intensive care in preterm infants with severe IVH.

Colonic atresia (CA) is the rare cause of intestinal obstruction, and diagnosis of CA is difficult. But only few research has been performed, so little information has been available. The purposes of this study was to analyze the clinical findings of CA so that help physicians make decision properly. Children with CA who were treated at the division of pediatric surgery at Asan Medical Center in the period from January 1989 to December 2011 were evaluated retrospectively. A total of 6 children were treated with CA. These accounted for 2.7% of all gastrointestinal atresias managed in Asan Medical Center. Only one child was premature and low birth weight, the others were fullterm neonates and showed normal birth weight. Vomiting and abdominal distension were common symptoms and simple X-ray and barium study were used for diagnose of CA. But only 66.7% of the babies were diagnosed as CA pre-operatively. And 2 children out of 6 underwent re-operation due to missed CA at the time of the first operation. In aspect of types of atresia, the type IIIa were two, type IV were two, type I was one case, and one child showed rectal stenosis due to rectal web. Various operations were done according to individual findings and associated diseases. The 50% (n=3) of children underwent the primary anastomosis and the others (n=3) underwent colostomy first and staged operation later for missed CA or associated disease. All of them were recovered any significant complications. Therefore, the prognosis of CA is satisfactory if diagnosis and surgical management could be made properly. But because of the low incidence of CA, delay of diagnosis and treatment may occur. To prevent delay of diagnosis, we suggest prompt evaluation of doubtful infant and careful inspection of distal patency of bowel including whole colon and rectum when operating patients with intestinal atresia at any level.

This retrospective clinical study was done based under the delivery records of 146 cases of twin pregnancies in Yonsei University, Severance Hospital and Wonju Christian Hospital from 1977 through 1980 with particular interest in the second twins. Clinical factors, Apgar scores related to neonatal prognosis, and perinatal mortality rate were statistically analyzed and the following results were obtained. The mean - birthweight for A (first) twins was 2,377 grams and for B (second) twins 2,296 grams. In comparison of the percentage of low-birth-weight (less than 2,500 grams) infants, there were more small B twins, but the difference was statistically not significant. Because there were no significant statistical differences in birth weight-grouping between A and B twins, they could be compared with the comprehensive Apgar scores, but this method was also shown to be statistically not significant. In comparison of the percentage of breech deliveries in A and B twins, the percentage was more than three times in B twin (A twin, 7.5 per cent; B twin, 24.0 per cent), and the difference was statistically very significant (p < 0.0005). There were no significant statistical differences between the Apgar scores of A and B twins in reference to the manner of delivery. According to the manner of delivery of B twins, spontaneous vertex delivery and total breech extraction revealed higher infant mortality rate than others. B twins presented by the vertex in 88 cases (61.0 per cent), by the breech in 55 cases (37.0 per cent), and by the shoulder in 3 cases (2.0 per cent). And this therefore disclosed no significant statistical differences in Apgar scores in relation to the presentation. The duration of labor appeared to have no clear correlation with the Apgar scores and the perinatal mortality of A and B twins. The delivery interval between A and B twins was 11.9 minutes on an. averge, varying from 3 to 65 minutes. The length of this interval was not found to have any significant effect on the Apgar scores and the perinatal mortality rate of B twin.

Background: We aimed to evaluate the efficacy and safety of early surgical ligation (within 15 days of age) over late surgical ligation (after 15 days of age) by a comparative analysis of very low birth weight (VLBW) infants undergoing surgical correction for symptomatic patent ductus arteriosus (PDA) over the course of 6 years in our hospital. Methods: We retrospectively reviewed all the medical records in the neonatal intensive care unit at Hanyang University Seoul Hospital, from March 2007 to May 2013, to identify VLBW infants (<1,500 g) who underwent surgical PDA ligation. Results: The gestational age (GA) in the late ligation (LL) group was significantly younger than in the early ligation (EL) group (p=0.010). The other baseline characteristics and preoperative conditions did not differ significantly between the two groups. The intubation period before surgery (p<0.001) and the age at surgery (p<0.001) were significantly different. The postoperative clinical outcomes of the study patients, including major morbidity and mortality, are summarized. There were no significant differences in bronchopulmonary dysplasia, sepsis, or mortality between the EL and the LL groups. However, the LL group was significantly associated with an increased risk of necrotizing enterocolitis (p=0.037) and with a prolonged duration of the total parenteral nutrition (p=0.046) after adjusting for GA. Conclusion: Early surgical ligation for the treatment of PDA that failed to close after medical treatment or in cases contraindicated for medical treatment might be desirable to reduce the incidence of necrotizing enterocolitis and to alleviate feeding intolerance in preterm infants.
