The objective of this study is to evaluate their stature and weight growth from 0 to 9 months of corrected age (CA) in Senegal. Methodology: This is a prospective, descriptive, and analytical cohort follow-up up to 9 months of CA including all live newborns of LBW hospitalized and followed up from 01 August 2019 to 31 May 2020. World Health Organization growth charts were used to assess stature and weight growth. Results: During the study 136 LBW newborns were included. The mean gestational age was 32 weeks of amenorrhea. At discharge, 46 children (33.82%) were exclusively breastfed. At birth, the mean weight was 1487 g (3<sup>rd</sup>-10<sup>th</sup> percentile) and the mean height was 41.52 cm (10<sup>th</sup>-25<sup>th</sup> percentile). At 9 months of CA, the mean weight was 8119 g (median) and the mean height was 74 cm (median). The children had achieved satisfactory growth in weight (84%) and height (89%). At 9 months of CA, 27% of the children were behind in one of the four areas of psychomotor development. Conclusion: At the end of 9 months of CA, stature and weighted growth was normal.展开更多

Nevertheless, there have been very few reports according to the recent outcome of the neonates with EA, and otherwise, time has come to re-evaluate the credibility of this classification. The aim of this study was to validate the recent prognosis of the EA. Methods: Patient data were collected from 22 cooperative facilities during the 5 year period from 2005 to 2009 in Kyushu area, Japan. Total of 100 EA patients were retrospectively reviewed according to their characteristics and the outcome. Patient who missed the characteristics and outcome was excluded from the respective data. Results: Only 29.8% (28/94) was prenatally diagnosed and 52.0 (52/100) had associated anomalies including major congenital heart disease (CHD), abnormal chromosome, and others. According to the operation, primary anastomosis was performed 57.0% (57/100) and the staged operation was performed 34.0% (34/100). Survival rate in the neonatal period was 89.0% (89/ 100), and overall survival rate was 78.0% (78/100). According to the Spitz classification, if patients with associated anomalies were excluded, survival rate of Group 1 (>1500 g and no CHD) was 93.8% (61/65), Group 2 (<1500 g or CHD) was 68.4% (13/19), and Group 3 (<1500 g and CHD) was 50% (1/2). Conclusion: EA was proved to be rarely diagnosed prenatally. Primary outcome of the Group 1 and Group 3 in Spitz classification were fairly good, but Group 2 was worse as ever. The comprehensive treatment strategy for EA patients with birth weight under 1500 g or CHD should be reconsidered to improve the overall outcome.展开更多
