PURPOSE
Volumetric tomography (3D-CT) is currently considered the gold standard for the diagnosis of craniosynostosis, but its use as the first-line examination for cranial deformities is a topic of debate, because of skull X-ray radiation and low sensitivity and specificity. Cranial ultrasound is an emerging noninvasive radiation-free alternative, but its diagnostic accuracy still needs confirmation.
MATERIALS AND METHODS
The present prospective study included 350 infants with skull deformities, who underwent cranial ultrasound as the first-line examination, followed by 3D-CT if the echography results was positive or unclear. If the results were negative, infants underwent physical treatment and follow-up. To evaluate ultrasound reliability, we focused on cases that underwent both the index test and the gold standard and performed a double-blind comparison of the echography and 3D-CT results.
RESULTS
Ultrasound documented patent sutures in 293 infants and 9 had inconclusive results. The 293 ultrasound-negative infants were followed clinically: all improved, except 28 that underwent 3D-CT. In all of these cases, 3D-CT confirmed the ultrasonography results (no false negatives). 48 infants showed premature suture closure and underwent 3D-CT: 47 were confirmed (true positive), 1 was false positive. The sensitivity was 100%, the specificity was 99.7%, the positive and negative predictive values were 97.9% and 100%, respectively, the accuracy was 99.7%, and the diagnostic test evaluation was conclusive.
CONCLUSION
The study documented the high sensitivity and specificity of echography for the diagnosis of craniosynostosis in a referral center, with better results being achieved before 6 months of age. Major limitations are the loss of diagnostic significance as the child grows and the learning curve needed. The advantages are avoidance of radiation and chance to evaluate the brain at the same time.

OBJECTIVE
Data from the academic medical centers in the United States showing improvements in survival of periviable infants born at 22 to 24 weeks GA may not be nationally representative since a substantial proportion of preterm infants are cared for in community hospital-based neonatal intensive care units. Our objective was to examine the national trends in survival and other short-term outcomes among preterm infants born at ≤24 weeks gestational age (GA) in the United States from 2009 to 2018.
STUDY DESIGN
This was a retrospective, repeated cross-sectional analysis of the National Inpatient Sample for preterm infants ≤24 weeks GA. The primary outcome was the trends in survival to discharge. Secondary outcomes were the trends in the composite outcome of death or one or more major morbidity (bronchopulmonary dysplasia, necrotizing enterocolitis stage ≥2, periventricular leukomalacia, severe intraventricular hemorrhage, and severe retinopathy of prematurity). The Cochran-Armitage trend test was used for trend analysis. -Value <0.05 was considered significant.
RESULTS
Among 71,854 infants born at ≤24 weeks GA, 34,251 (47.6%) survived less than 1 day and were excluded. Almost 93% of those who survived <1 day were of ≤23 weeks GA. Among the 37,603 infants included in the study cohort, 48.1% were born at 24 weeks GA. Survival to discharge at GA ≤ 23 weeks increased from 29.6% in 2009 to 41.7% in 2018 ( < 0.001), while survival to discharge at GA 24 weeks increased from 58.3 to 65.9% ( < 0.001). There was a significant decline in the secondary outcomes among all the periviable infants who survived ≥1 day of life.
CONCLUSION
Survival to discharge among preterm infants ≤24 weeks GA significantly increased, while death or major morbidities significantly decreased from 2009 to 2018. The postdischarge survival, health care resource use, and long neurodevelopmental outcomes of these infants need further investigation.
KEY POINTS
· Survival increased significantly in infants ≤24 weeks GA in the United States from 2009 to 2018.. · Death or major morbidity in infants ≤24 weeks GA decreased significantly from 2009 to 2018.. · Death or surgical procedures including tracheostomy, VP shunt placement, and PDA surgical closure in infants <=24 weeks GA decreased significantly from 2009 to 2018..

Patent ductus arteriosus (PDA) has been associated with increased morbidity and mortality in preterm infants. Surgical ligation (SL) is generally performed in symptomatic infants when medical management is contraindicated or has failed. We retrospectively reviewed our institution's experience in surgical management of PDA for extremely low birth weight (ELBW) infants without chest tube placement assessing its efficiency and safety. We evaluated 17 consecutive ELBW infants undergoing SL for symptomatic PDA (January 2012-January 2018) with subsequent follow-up for 6 months postdischarge. Patients consisted of 9 (53%) females and 8 (47%) males. Mean gestational age (GA) at birth was 27.9 ± 2.1 weeks. Median values for surgical age (SA) from birth to operation was 10 days (interquartile range [IQR]: 8-12); PDA diameter 3.4 mm (IQR: 3.2-3.5); surgical weight (SW) 750 g (IQR: 680-850); and days of mechanical ventilation (DMV) as estimated by Kaplan-Meier curve 22 days (95% confidence interval: 14.2-29.8). We observed a statistically significant negative association between DMV and GA at birth (rho = - 0.587, = 0.017), SA (rho = - 0.629, = 0.009) and SW (rho = - 0.737, = 0.001). One patient experienced left laryngeal nerve palsy confirmed by laryngoscopy. Otherwise, there were no adverse events to include surgical-related mortality, recurrence of PDA, or need for chest tube placement during follow-up. SL of PDA in ELBW infants without chest tube placement is both efficient and safe. Universal consensus recommendations for the management of PDA in ELBW neonates are needed. Further study is required regarding the use of the less invasive option of percutaneous PDA closure in ELBW infants.
