Polysomnographic and psychometric correlates of napping in primary insomnia patients.

This study aims to evaluate napping in patients with insomnia compared with two control groups and to investigate the relationships between psychometric measures and napping habitude. Sixty-eight adult patients with chronic primary insomnia were enrolled; 27 men and 41 women, mean age 53.6 ± 13.

Sleep disorders in low-risk preschool very preterm children.

Objectives: (i) to assess the presence of sleep disorders in a population of very preterm children (ie, with a gestational age [GA] ≤ 31 weeks) of preschool age with no history of neurological disabilities using a questionnaire standardized for this age group and (ii) to identify possible differences in a control group of term-born children.

Methods: A total of 146 low-risk preterm children (mean gestational age 28 weeks; range: 25-30), were assessed at a preschool age (mean age 3.8 years; range 3-6 years) using the sleep disturbance scale for children (SDSC) to assess sleep problems.

Brain morphometry of preschool age children affected by autism spectrum disorder: Correlation with clinical findings.

The aim of our study was to use a combined imaging and clinical approach to identify possible patterns of clinical and imaging findings in a cohort of preschool age autism spectrum disorder (ASD) patients. In order to identify imaging patterns that could be related to specific clinical features, a selected group of ASD patients (age range 3-6 years) without dysmorphic features, epilepsy or other major neurological signs, malformations or other lesions at MRI was subjected to brain volumetric analysis using semiautomatic brain segmentation. An age-matched group of typically developing children was subjected to the same analysis.

6MWT can identify type 3 SMA patients with neuromuscular junction dysfunction.

The aim of the study was to establish if the decrease in gait velocity on the 6 minute walk test relates to signs of neuromuscular junction dysfunction in spinal muscular atrophy type 3 patients. 6 minute walk test and low-rate repetitive nerve stimulation test were performed in fifteen ambulant patients with spinal muscular atrophy type 3 of age between 9 and 66 years. The 6 minute walk distance ranged between 66 and 575 m.
