ReviewNeonatal and longer term management following substance misuse in pregnancy.
Substance misuse in pregnancy is not a new problem, but although impaired foetal growth and the risk of developing neonatal abstinence syndrome are widely appreciated, relatively little attention has been paid to longer term consequences for the infant. Available evidence indicates that prenatal exposure to opioids and other drugs of misuse is detrimental to the developing foetal brain; consistent with this, poor in utero head growth, delayed infant visual maturation and impaired general neurodevelopmental progress independent of social confounders are increasingly being recognised. ⋯ More studies are required to explore alternatives to methadone maintenance in pregnancy and to define optimal treatment for neonatal abstinence syndrome. All infants born to drug-misusing mothers must be considered vulnerable, even if they have not required treatment for neonatal abstinence syndrome.

Children's interstitial lung disease (ILD) includes a wide range of rare respiratory disorders associated with high morbidity and mortality. Genetic factors, systemic disease processes, nonspecific inflammatory or fibrotic patterns of repair seen in a number of clinical settings are involved in the ILD pathogenesis. ⋯ The diagnostic approach is based on a combination of history/physical examinations, imaging studies, pulmonary function testing, genetic testing, bronchoalveolar lavage (BAL) and in most cases an open lung biopsy. Although some disease types overlap with those seen in adults, in this review emphasis is placed on entities unique to the pediatric population focusing on clinical characteristics, histologic definitions, radiologic-pathologic correlation and therapeutic strategies.

Non-invasive positive pressure ventilation is increasingly used in children both in acute and in chronic setting. Clinical data supporting safety, efficacy and limitations in children are growing. ⋯ Non-invasive ventilation can be applied at home. Its use at home requires appropriate diagnostic procedures, accurate titration of the ventilators, cooperative and educated families and careful, well-organized follow-up programs.

Preoperative left ventricular internal dimension in end-diastole as earlier identification of early patent ductus arteriosus operation and postoperative intensive care in very low birth weight infants.
Patent ductus arteriosus (PDA) is common in premature infants. In very low birth weight infants (VLBWI), PDA requires surgical therapy in many cases. It is unclear to know at-risk infants showing cardio-dysfunction after PDA surgery. ⋯ Preoperative relative LVIDd was significantly larger in abnormal FS infants (137 ± 18%) than in normal FS infants (118 ± 11%; p<0.01). A cut-off value of preoperative relative LVIDd (absolute LVIDd/normal value) for predicting postoperative cardio-dysfunction was 127.4% (sensitivity, 0.735; specificity, 0.933; area under curve, 0.817). Determination of preoperative LVIDd might facilitate earlier identification of infants needing early PDA surgery and postoperative intensive care.

Preterm birth, respiratory failure and BPD: which neonatal management?
Preterm birth is a significant problem in the world regarding perinatal mortality and morbidity in the long term, especially bronchopulmonary dysplasia (BPD). Premature delivery is often associated to failure in transition to create an early functional residual capacity (FRC), since many preterm babies need frequently respiratory support. The first and most effective preventive measure to reduce the incidence of BPD is represented by the attempt to avoid preterm birth. Whenever this fails, the prevention of every known risk factors for BPD should start in the delivery room and should be maintained in the NICU through the use of tailored management of high-risk infants.
