  • The ultimate goal of the term alteration to pediatrics is that not only infants and children but also adlescents are subjet to pediatrics. At 27, June, 2007 the term pediatrics was altered to pediatrics (children and aoldescent medicine). From now on the roles of pediatricians for adolescents are needed and adolescent medicine should be reorganized in Korea. Although the numbers of children are decreased in the times of low birth rate, the efforts of pediatricians try to enlarge the range of treatment for adolescents are need.

  • Ninety pre-puberal (6-7 months) female and 15 pre-puberal male Black Bengal goats were collected on the basis of their phenotypic characteristics from different parts of Bangladesh. Goats were reared under semi-intensive management, in permanent house. The animals were vaccinated against Peste Des Petits Ruminants (PPR), drenched with anthelmentics and deeped in 0.5% Melathion solution. They were allowed to graze 6-7 h along with supplemental concentrate and green forages. Concentrates were supplied either 200-300 g/d (low level feeding) or quantity that supply NRC (1981) recommended nutrient (high level of feeding). Different physiological, productive and reproductive characteristics of the breed were recorded. At noon (temperature=$95^{\circ}F$ and light intensity=60480 LUX) rectal temperature and respiration rate of adult male and female increased from 100.8 to $104.8^{\circ}F$ and 35 to 115 breath/min, indicated a heat stress situation. Young female attain puberty at an average age and weight of 7.2$\pm$0.18 months and 8.89$\pm$0.33 kg respectively. Mean age and weight at 1st kidding were 13.5$\pm$0.49 months and 15.3$\pm$0.44 kg respectively. It required 1.24-1.68 services per conception with an average gestation length of 146 days. At low level of feeding the postpartum estrus interval was 37$\pm$2.6 days, which reduced (p<0.05) with high feeding level to 21$\pm$6.9 days. Kidding interval also reduced (p<0.05) from 192 d at low feeding level to 177 d at high feeding level. On an average there were two kiddings/doe/year. Average litter sizes in the 1st, 2nd, 3rd and 4th parity were 1.29, 1.71, 1.87 and 2.17 respectively. Birth weights of male and female kids were 1.24 and 1.20 kg respectively, which increased (p<0.05) with better feeding. Although kid mortality was affected (p<0.05) by dam's weight at kidding, birth weight of kid, milk yield of dam, parity of kidding, season of birth, but pre-netal dam's nutrition found to be the most important factor. Kid mortality reduced from 35% at low level of feeding to 6.5% at high level of feeding of dam during gestation. Apparently, this was due to high (p<0.05) average daily milk yield (334 vs. 556 g/d) and heavier and stronger kid at birth at high feeding level.

  • 목 적 : 최근 신생아 집중 치료의 발달로 인하여 출생체중 1,500 g 미만의 극소 저체중출생아(very low birth weight infants, VLBWI)의 생존율이 높아지고 있다. 이에 저자들은 최근 12년간 한림대학교 강남성심병원 신생아 중환자실에 입원한 극소 저체중 출생아의 치료 결과의 변화를 조사하였다. 방 법 : 1997년 1월 1일부터 2008년 12월 31일까지 한림대학교 강남성심병원 신생아 중환자실에 입원한 1,500 g 미만의 VLBWI 339명을 대상으로 하였고 I기(1997-2003년), II기(2004-2008년)로 나누어 각기별 출생체중과 재태연령의 변화, 생존율, 이환율, 사망원인 및 시기에 대해 병록지 검토를 통해 후향적으로 조사하였다. 결 과 : VLBWI 발생 빈도는 II기에 유의하게 증가하였으며 평균 출생체중 및 재태 연령도 I기에 비해 II기에 유의하게 감소하였으나 1분과 5분 아프가 점수는 II기에 더 높았고(P<0.05), 인공 호흡기 사용기간, 산소 총 투여 기간에는 두 기간사이의 통계적으로 유의한 차이는 없었다(P>0.05). 산모와의 관계를 보면 자궁경부 근무력증, 출생 전 스테로이드 사용, 조기 양막파수는 II기에 유의하게 증가하였다. 생존율에 있어서는 I기에 59.1%, II기에 74.2%로 유의한 증가를 보였으며(P<0.05), 출생체중 1,000 g 미만, 재태연령 28주 미만의 환아의 생존율 증가가 두드러졌다. 극소 저체중 출생아에서 흔히 동반되는 질환으로는 호흡곤란 증후군, 미숙아 망막증, 패혈증, 기관지폐 형성이상, 동맥관 개존증, grade III 이상의 뇌실 내 출혈 및 뇌백질 연화증, 괴사성 장염의 발생은 동맥관 개존증을 제외하고는 두 기간 간의 유의한 차이는 없었다. 사망 원인으로는 호흡곤란 증후군이 가장 많았고 폐출혈, 패혈증이 그다음을 차지하였고, 사망 시기는 두 기간 모두 7일 이내 사망률이 가장 높았다. 결 론 : 최근 12년간 본원에서 출생한 VLBWI의 생존율은 현저히 향상되었으며 특히 1,000 g 미만 28주 미만 환아에서의 생존율 향상이 두드러졌다. 이는 여러 가지 신생아 집중치료술의 향상에 따른 것으로 생각된다. 하지만, 아직 초기 사망율이 높으므로 급성기 치료에 더욱 관심을 갖고 출생체중, 재태연령, 산소치료등과 밀접한 관계가 있는 합병증인 기관지폐 형성이상, 미숙아 망막증 등의 빈도를 줄이기 위해 노력해야 할 것으로 생각된다.

  • Gestational age and infant birth weight are influenced by gestational weight gain. This study was aimed to examine the effects of gestational weight gain on pregnancy outcomes. Pregnant women were recruited at two hospitals in Seoul area. Characteristics and dietary intakes of pregnant women were obtained using 24-hour recall questionnaires. Gestational weight gain was categorized as less (Under-gain) than, within (Recommended gain), or greater (Over-gain) than the Institute of Medicine guidelines. Maternal height and pre-pregnancy weight in the over-gain group significantly higher than under-gain and recommended gain group. Mini dietary assessment score of eating bean has significantly higher in under-gain group than recommended gain group and eating kimchi has significantly higher in undergain group than over-gain group. Score of eating fruit was significantly higher in over-gain group than other groups. The mean intake of carbohydrate in the recommended gain group were significantly higher than under-gain group, and mean intake of potassium in the over-gain group were significantly higher than under-gain group. Under-gain group showed the high rate of the preterm delivery and low birth weight infant delivery. However recommended gain group showed 46% reduced risk of preterm delivery (OR = 0.54 CI = 0.30-0.98). Risk of macrosomia increased with increasing gestational weight gain (p for trend < 0.05). In conclusion, pregnancy outcomes were influenced by gestational weight gain. Therefore, these finding suggested adequate gestational weight gain according to BMI for reducing the risk of preterm delivery, low birth weight and macrosomia.

  • 본 연구는 인구조사 통계자료를 이용하여 개인적, 가족적, 사회적 요인들이 부산광역시의 지속적인 낮은 출산율과 어떻게 관련되어 있는지 살펴보며, 출산율을 높이기 위한 가족친화환경조성에 관한 정책들도 제시하고자 하였다. 최근 몇 년간 부산광역시의 출산율은 전국의 광역시도 중 가장 최저로 나타났으며 부산지역의 특징을 보여주고 있다. 출산율은 만혼 및 임신의 고령화, 혼인율 감소, 높은 이혼율, 미혼여성들의 결혼기피현상, 남성들의 전통적 성역할태도, 맞벌이 남성들의 저조한 가사분담참여, 낮은 결혼만족도와 가족생활만족도, 높은 낙태율과 같은 복합적인 가족학적 요인들과 가족정책, 자녀양육시설의 이용가능성, 교육비 및 사회와 기업의 가족친화 수준과 같은 보다 광의의 특성들 때문에 낮게 나타난다. 부산 여성들은 전통적 성역할 규범과 관습이 유지되는 사회 환경에서 맞벌이를 하는 경우에도 과중한 가사노동을 수행하고 있었고, 부부의 결혼만족도도 전국평균보다 낮았는데 부인의 결혼만족도는 남편에 비해 전국평균보다 더욱 낮게 나타났다. 부산광역시의 출산율 향상을 위하여 이 요인들의 시사점들과 가족 친화적 정책제안들도 8가지 측면에서 논의되었다.

  • Data spread over 11 years (1986-1996) pertaining to a synthetic population developed by inter se mating of half-breds of Corriedale and Russian Merino with Nali maintained at CCS Haryana Agricultural University, Hisar were utilized for the estimation of genetic parameters for growth traits. The means for birth weight (BWT), weaning weight (WWT), six month body weight (SWT), yearling weight (YWT), preweaning daily gain (PRW) and post weaning daily gain (POW) were 3.35 kg, 10.79 kg, 13.28 kg, 18.96 kg, 82.6 gm and 27.6 gm, respectively. The effects of year and season of birth and sex of lamb were significant for all the traits under study except the effect of season of birth for WWT, SWT and PRW. No definite trend was observed over the years for the averages of body weight and gain. Lambs born during the spring season performed better for BWT, WWT and PRW while the performance of lambs born during autumn was better for the other traits included in the study. The male lambs were heavier than the females for body weight at all stages and gain in weight. The heritability estimates for WWT and PRW were low; for BWT and SWT were moderate and for YWT and POW were high. Birth weight had high heritability and high genetic correlations with subsequent body weights and gains but due to the presence of a maternal effect on BWT and WWT, a sequential selection procedure is recommended for the improvement of growth rate in sheep.

  • 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.

  • Maternal zinc deficiency is relatively common worldwide, but its consequences for pregnancy outcome are not established. The purpose of this study was to examine the effect of zinc status in the second trimester on pregnancy outcome. Subjects were 248 pregnant Korean women (25-28 wk gestation). Cord blood was collected from subgroup of 69 women and pregnancy outcome data were obtained from 185 babies. Anthropometry measurement, dietary intake, and biochemical characteristics of pregnancy and cord serum substances were measured. The subjects were divided into quartiles on the basis of maternal serum Zn concentration; $ZnQ_1$ (< 25 percentile), $ZnQ_2$ ($26\~50$ percentile), $ZnQ_3$ ($51\~75$ percentile), and $ZnQ_4$ ($76\~100$ percentile). Zn groups were compared in terms of various maternal factors, concentrations of cord serum substances, and pregnancy outcome. Maternal serum Zn concentration was $118.4\;{\pm}\;35.5\;{\mu}g/dl$ as mean. Intake of Zn was lower than Korean RDA. The rate of Zn deficiency among all subjects was $8.5\%$. Maternal serum Zn levels belonged to normal range. Cord serum Zn level was about $154.7\%$ of maternal serum level. Intakes of energy, calcium, iron, folic acid, and riboflavin did not meet the Korean RDA for pregnant women by gestational age. The mean birth weight of neonates is 3083 $\pm$ 697 g, of whom $9.1\%$ were of low birth weight (< 2,500 g). Maternal serum Zn level was positively correlated with pre-pregnancy weight, pre-pregnancy body mass index, and vitamin C intake (p < 0.05). $ZnQ_1$ group had significantly lower maternal serum iron concentration and higher cord serum cholesterol than those in other groups. Maternal serum Zn level, cord serum Zn level, and dietary Zn intake were no related to the pregnancy outcome. The birth weight had a correlation with the maternal hemoglobin and albumin concentration. In conclusion, at this study, we could not find the association with maternal Zn status in 2nd trimester and pregnancy outcome.
