Purpose: Smoking during pregnancy contributes to the risk of negative health outcomes in mothers and babies. The purposes of this study were to review the harmful effects of maternal smoking during pregnancy on fetal and child development, to discuss if maternal smoking should be criminalized as a form of child abuse, and to explore advocating for fetal rights. Methods: A variety of published literature and legal documents including the Korean constitution, criminal laws, and children's welfare laws were reviewed and critically analyzed. Results: Women who smoke during pregnancy are more likely to experience abortion related to placental dysfunction. Their unborn risk premature birth, fetal growth restriction, low birth weight, neurobehavioral disturbances, and/or other complications and newborn babies are also at risk for complications. The advocates for fetal rights can assert that maternal smoking should be regarded as a crime. Conclusion: Findings show that maternal smoking during pregnancy is a major risk factor for many adverse pregnancy outcomes. Effective strategies and health policies for smoking cessation during pregnancy are required to protect pregnant women and their babies.

Purpose: An exploratory study was done to examine the validity of the new Ballard scale with extended scoring system(eNBS) in estimating gestational age(AG) in full-term newborns. Method: The eNBS scoring system was extended to include all numbers of total score of NBS and GA to allow a 3-days variation in GA estimatio compared to the original scale which has a 2-week variation due to the application of a 5-score interval for the total NBS score and only even numbers for GA. GA by eNBS(GA-eNBS) was compared with GA by LMP(GA-LMP) and GA by standard NBS(GA-sNBS) in 133 full-term newborns. Difference between GA-LMP and GA-eNBS was analyzed for each GA. Results: Positive correlations were observed in GA-sNBS and GA-eNBS with GA-LMP. There was no difference between GA-LMP and GA-eNBS at 39GA and 40GA. At 37GA and 38GA, GA-eNBS overestimated GA-LMP up to 1 week, while underestimating up to 1 week at 41GA. Conclusions: The accuracy of eNBS was validated within 3 days of variation in GA estimation at 39-40GA. Overestimation by eNBS suggests the possible acceleration of fetal maturity in premature newborns, while underestimation, of the deceleration of fetal maturity in postterm newborns.

Morphogenesis of rat spleen was studied by light and electron microscope from the fetal stage till the newborn or adult stages. The results indicate as follows: at the 14th day of gestation rat spleen, as an early form, consists of intercellular spaces and mesenchymal cells. And at this stage the spleen is in a premature state, then it appears its adult condition in structures after the 7th postnatal day. Erythropoiesis is shown to be an active process in rat spleen beginning about the 18th day of gestation, and once established the process continues at least till the 7th postnatal day. At the 20th day of gestation, there are splenic nodules, trabeculae, venous sinus, and granular leucocytes such as neutrophils and basophils in rat spleen. Lymphocytes appeared to be well differentiated at the 7th postnatal day and were present till the adult stage. While degenerating erythrocytes are phagocytosed by macrophages. In conclusion, rat spleen started to be appeared from the 14th day of gestation and erythropoiesis in rat spleen was carried out for about 10 days between prenatal and postnatal stage. Erythrophagocytosis was accomplished by macrophages and it is suggested that the proper functions of rat spleen set off from the 7 th postnatal day when its structures are similar to the adult's.

Subglottic cysts have been reported as a relatively rare problem of pediatrics who have a history of premature birth and period of intubation. They may cause significant upper airway obstruction and many cases require tracheostomy to airway management. Endoscopic marsupialization by microinstruments or laser has been standard primary treatment but a high recurrence rate has been reported. A 19-month-old child presented with stridor who has history of ventilation via an endotracheal intubation in the newborn period for 7 days. Radiologic examinations were performed for aggravated dyspnea symptom and subglottic cystic mass was found, then it was marsupialized at operation room and tracheostomy was done at the same time. After decannulation of tracheostomy tube, there is no recurrence of cyst nor upper airway obstruction for 29 months. We report this case with a review of literature.

In Korea, pulmonary surfactant (PS) replacement therapy in respiratory distress syndrome (RDS) was started in 1991 since when Surfacten$^{(R)}$ was imported from Japan. At the present time, Surfacten$^{(R)}$, Newfactan$^{(R)}$, Curosurf$^{(R)}$, and Infasurf$^{(R)}$ are available in Korea. The governmental health insurance covers the expense for multiple dose treatment since 2002 and the early prophylactic treatment (BW: <1,250 g or GP: <30 wks) since 2011. We undertook a multi-institutional collective study to evaluate the outcomes of PS over past 20 years in Korea (Period-I; 1990/91, P-II; 1996, P-III; 2002, and P-IV; 2007, P-V; 2010). There were 60 RDS neonates with PS treatment in P-I (16 hospitals), 1,179 in P-II (64), 1,595 in P-III (62), 1,921 in P-IV (57), and 3,160 in P-V (72). Decreased mortality rate, defined as the percentage of neonates who died within 28 days of birth, was seen between periods, P-V vs P-I, II, III, and IV (mortality rate: 10.1% vs. 40.0%, 30.0%, 18.7%, and 14.3%). We conclude that PS therapy contributed to improve remarkable outcome in RDS neonates over the last 20 years in Korea. However, more efforts should be made to optimize PS therapy for better outcome. Multiple PS doses for relapse and poor response, early prophylactic use, and better supportive care for pre-term infants are mandatory.

Purpose: Although procalcitonin (PCT) level is useful for the diagnosis of neonatal sepsis, PCT reliability is inconsistent because of the varied conditions encountered in neonatal intensive care units. This study aimed to investigate PCT levels and factors influencing increased PCT levelin newborns without bacterial infection during the first week of life. Methods: In newborns hospitalized between March 2013 and October 2015, PCT levels were measured on the first, third, and seventh days after birth. Newborns with proven bacterial (blood culture positive for bacteria) or suspicious infection (presence of C-reactive protein expression or leukocytosis/leukopenia) were excluded. Various neonatal conditions were analyzed to identify the factors influencing increased PCT level. Results: Among 292 newborns with a gestational age of $35.2{\pm}3.0$ weeks and a birth weight of $2,428{\pm}643g$, preterm newborns (n=212) had higher PCT levels than term newborns (n=80). Of the newborns, 7.9% had increased PCT level (23 of 292) on the firstday; 28.3% (81 of 286), on the third day; and 3.3% (7 of 121), on the seventh day after birth. The increased PCT level was significantly associated with prenatal disuse of antibiotics (P=0.004) and surfactant administration (P<0.001) on the first day after birth, postnatal use of antibiotics (P=0.001) and ventilator application (P=0.001) on the third day after birth, and very low birth weight (P=0.042) on the seventh day after birth. Conclusion: In newborns without bacterial infection, increased PCT level was significantly associated with lower gestational age and respiratory difficulty during the first week of life. Further studies are needed for clinical applications.
