Deformational plagiocephaly is reported in up to 46.6 % of healthy infants, with the highest point prevalence at around 3 months of age. Few prospective studies on the natural course of skull deformation have been conducted, and we know of no studies using 3D imaging starting from the highest point prevalence period. In this prospective, population-based cohort study, we describe the course of cranial asymmetry and shape in an unselected population using 3D stereophotogrammetry and investigate factors associated with late cranial deformation and failure to recover from previous deformation. ⋯ Positional preference at 3 months predicted an unfavorable course of cranial asymmetry after 3 months, increasing the risk for DP persisting. What is known: • The prevalence of deformational plagiocephaly spontaneously decreases after the first months of life. • Limited neck range of motion and infant positional preference increase the risk of deformational plagiocephaly during the first months of life. What is new: • Positional preference at 3 months predicts an unfavorable spontaneous course of deformation also from three to 12 months of age, presenting a potential target for screening and treatment. • The spontaneous rate of correction for cranial asymmetry decreases after 6 months of age, also in relation to the rate of head growth.

The role that rhinoviruses, enteroviruses, parainfluenza viruses, coronaviruses and human bocavirus play in pediatric pneumonia is insufficiently studied. We used polymerase chain reaction (PCR) to study 9 virus groups, including 16 different viruses or viral strains, in 56 ambulatory children with radiologically confirmed community-acquired pneumonia (CAP). The same tests were carried out on 474 apparently healthy control children of the same age and sex. ⋯ Adenoviruses were present in 12.5 % of cases (0.2 % controls) and metapneumovirus and influenza A virus each in 10.7 % of cases (0.2 % controls). Interestingly, rhinoviruses were less common in cases (10.7 %) than in controls (22.4 %): odds ratio 0.36 (95%CI) 0.15-0.87) in conditional logistic regression including 56 cases and 280 controls matched for age, sex and sampling month. The prevalence of parainfluenza viruses, enteroviruses, coronaviruses and human bocavirus were similar in both groups.

Review Meta Analysis
Surfactant instillation in spontaneously breathing preterm infants: a systematic review and meta-analysis.
Less invasive surfactant therapies (LIST) use surfactant instillation through a thin tracheal catheter in spontaneously breathing infants. This review and meta-analysis investigates respiratory outcomes for preterm infants with respiratory distress syndrome treated with LIST rather than administration of surfactant through an endotracheal tube. Randomised controlled trial (RCT) full texts provided outcome data for bronchopulmonary dysplasia (BPD), death or BPD, early CPAP failure, invasive ventilation requirements and usual neonatal morbidities. ⋯ LIST resulted in decreased risks of BPD (RR = 0.71 [0.52-0.99]; NNT = 21), death or BPD (RR = 0.74 [0.58-0.94]; NNT = 15) and early CPAP failure or invasive ventilation requirements (RR = 0.67 [0.53-0.84]; NNT = 8 and RR = 0.69 [0.53-0.88]; NNT = 6). Compared to InSurE, LIST decreased the risks of BPD or death (RR = 0.63 [0.44-0.92]; NNT = 11) and of early CPAP failure (RR = 0.71 [0.53-0.96]; NNT = 11). Common neonatal morbidities were not different.
