Preterm birth is a major risk factor for children’s development. It affects children’s cognitive and intellectual development and is related to impairments in IQ, executive functions, and well-being, with these problems persisting into adulthood. While preterm children’s intellectual and cognitive development has been studied in detail, their social development and social-cognitive competencies have received less attention. Namely, preterm children show problems in interactions with others. These interaction problems are present in relationships with parents, teachers, and peers. Parents’ behavior has been identified as a possible mediator of children’s social behavior. Maternal sensitivity and responsiveness as well as absence of mental disorders foster children’s social development. In this article, we will report on the social side of impairments that preterm children face. The review of the literature revealed that preterm infants’ joint attention abilities are impaired: They are less likely to initiate joint attention with others and to respond to others’ efforts to engage in joint attention. These deficits in joint attention might contribute to later impairments in social cognition, which in turn might affect social interaction skills. Based on these three domains (i.e., problems in social interaction, parental behavior, and impairments in joint attention), we suggest that preterm children’s social cognitive abilities should be investigated more intensively.

Implementation of the LISA method on a neonatal ward was safe and feasible and was associated with less need for mechanical ventilation in infants >24 weeks. As our study was retrospective the observed trends for better pulmonary and neurocognitive outcomes should be interpreted with caution until results from randomized trials on the LISA procedure are available.

Canavan disease (CD; MIM 271,900) or spongy degeneration of the central nervous system (CNS) is a lethal, rare autosomal recessive leukodystrophy, first described in 1931 (Canavan in Arch Neurol Psychiatry 25: 299–308, 1931). The clinical presentation includes severe neurologic impairment and macrocephaly with onset of symptoms at the age of 3–5 months. Biochemical and genetic fundamentals of the disease are elucidated. Imaging diagnosis is principally based on MRI with important role of MR spectroscopy. We report the cerebral sonographic findings in a severely affected infant with CD: Diffuse hyperechogenicity and small multicystic changes of white matter as well as an inverted pattern of echogenicity between cortical gray and subcortical white matter. These findings are compared to to the few cases found in literature and to normal ultrasound examples. Finally, ultrasound and MRI imaging findings are correlated.
