    ABSTRACT: This study aims to evaluate the impact of small for gestational age (SGA) on mortality and morbidity in very low birth weight (VLBW) infants. We conducted a retrospective cohort study on VLBW infants registered at the Premature Baby Foundation of Taiwan between 2007 and 2011. All 21 neonatal departments in Taiwan participated in the data collection, and a total of 4636 VLBW infants were registered during the study period. The SGA group (n = 560) was selected from the database on the basis of birth weight below the 10(th) percentile for gestational age, whereas the appropriate weight for gestational age (AGA) group (n = 1120) included infants randomly selected via incidence density sampling with a 2:1 match for each SGA case. The association of SGA with individual outcome variables including mortality, respiratory distress syndrome, necrotizing enterocolitis, retinopathy of prematurity (ROP), intraventricular hemorrhage, periventricular leukomalacia, and bronchopulmonary dysplasia (BPD) was evaluated after adjustment for potential confounders. The SGA group was associated with increased risks of mortality [odds ratio (OR) 1.89; 95% confidence interval (CI) 1.39‒2.58], severe ROP (OR 1.56; 95% CI 1.13-2.14), and BPD (OR 2.08; 95% CI 1.58-2.75) compared to the AGA group. Further subgroup analysis showed that SGA had significant effects on mortality in the VLBW infants with a gestational age of 24-29 weeks, as well as on BPD in those with a gestational age of 27-32 weeks. By contrast, the association of SGA with severe ROP was only significant in the VLBW infants with a gestational age of 27-29 weeks. Our data provide evidence that SGA may be associated with increased risks of neonatal mortality, ROP, and BPD in VLBW infants. Copyright © 2014. Published by Elsevier B.V.

    ABSTRACT: Intrauterine exposure to tobacco smoke has been discerned as an important risk factor for low birth weight (LBW), small for gestational age (SGA), and preterm birth infants. In this cohort study, we investigated the association of the amount of parental smoking during the different pregnancy stages with birth weight and the incidence of preterm delivery. Our study population was acquired from the Taiwan Birth Cohort Study. Between June 2005 and July 2006, 21,248 postpartum women were interviewed 6 months after their deliveries by a structured questionnaire. The parents were divided into four groups according to the amount of smoking during preconception, the first trimester, and the second and third trimesters. The relationships of parental smoking with gestational age and birth weight during the different pregnancy stages were assessed using multivariate linear regression. Multiple logistic regression analyses were performed to estimate the odds ratios and 95% confidence intervals of preterm delivery, LBW, and SGA infants during the different parental smoking status and the different pregnancy stages. After adjusting for the physical and socioeconomic status of the parents and for paternal smoking during the same period, we found that maternal smoking decreased birth weight. Compared with the nonsmoking groups, all the maternal smoking groups had higher incidences of LBW, SGA, and preterm birth infants, especially when the mothers smoked >20 cigarettes/day. The association of paternal smoking with LBW, SGA, and preterm birth infants was insignificant. Maternal smoking is responsible for increased incidences of LBW and preterm delivery of babies, and therefore, smoking cessation/reduction should be advised to pregnant women to reduce morbidities in their neonates. Further studies are needed to clarify the correlation of fetal health with passive smoking, including exposure to environmental tobacco smoke and to other smokers in the family.

    ABSTRACT: Patients with congenital duodenal obstruction (CDO) predominantly have a postampullary lesion site and a high association with Down syndrome, according to previous reports from Western countries. This study aimed to determine whether there are racial differences in the clinical characteristics of congenital duodenal obstruction, based on the experience from a Taiwanese medical center. The charts were retrospectively reviewed among neonates with CDO who received surgery at National Taiwan University Hospital during the period 1985- 2008. Patients were grouped into a preampullary or postampullary group according to the obstruction in relation to the ampulla of Vater. Other characteristics, including sex, time of diagnosis, operative findings, as well as associated anomalies, were recorded for further analysis. A total of 30 patients with CDO including 16 with atresia, 10 with mucosal webs, and 4 with stenosis, were recruited; among them, 16 were boys and 14 were girls. In 15 patients (50%), the diagnosis of duodenal obstruction was made prenatally. A total of 11 of the 30 patients (37%) were in the preampullary group and 19 (63%) were in the postampullary group. Seventeen patients (56.7%) had at least one additional anomaly, including four (13%) who had trisomy 21. The preampullary group had significantly fewer associated congenital anomalies than in the postampullary group (27%vs. 74%, p = 0.012). Our cohort showed a relatively lower incidence of postampullary lesions and associated Down syndrome in patients with CDO compared with Western countries. Additionally, patients with preampullary lesions had significantly less association with other anomalies.

    ABSTRACT: Deciduoid mesothelioma is an extremely rare variant of malignant epithelioid mesothelioma. This report presents the case of a 13-year-old boy with this type of tumor in his pleura, whose initial main symptoms were chest pains and progressive scoliosis. Ensuing chemotherapy, which comprised pemetrexed and cisplatin, yielded good response after 5 cycles. Subsequent radical surgery was carried out and another 3 cycles of chemotherapy were given. The patient has been doing well 2 years after completion of this regime of treatment.

    ABSTRACT: Listeria monocytogenes is an important pathogen in neonates in Western countries, with a fatality rate of 20-30%. There is limited information on neonatal listeriosis in Eastern countries. The purpose of this study was to delineate the occurrence and clinical picture of neonatal listeriosis in Taiwan. A questionnaire-based survey of all of the 17 medical centers in Taiwan was performed, and a literature review of neonatal listeriosis as reported in Taiwan from 1990 to 2007 was made. A total of 14 cases (10 male, four female) of neonatal listeriosis were identified, including 11 found from the survey of four medical centers and another three collected from the literature review. Three were found to have occurred prior to 2000 and 11 were found to have occurred after 2000. The age of onset was less than 3 days in all cases. L. monocytogenes was identified from blood in 13, cerebrospinal fluid in four, and gastric aspirate in two. Half of the cases (7/14) had involvement of the central nervous system with pleocytosis and hypoglycorrhachia in cerebrospinal fluid, and three of them even developed hydrocephalus. The mortality rate was 29%. Our findings suggest that listeriosis may emerge as an important health threat among newborn infants in Taiwan.
