Objectives: This study examines the associations between the median nerve (MN) shear wave elastography (SWE), the MN cross‐sectional area (CSA), patient's symptoms, and the neurophysiological severity of carpal tunnel syndrome (CTS). The most appropriate site to perform SWE was also tested. Methods: This prospective study comprised 86 wrists of 47 consecutive patients who volunteered for MN ultrasound after an electrodiagnostic study. The neurophysiological severity of CTS was assessed according to the results of a nerve conduction study (NCS). The MN CSA was measured at the carpal tunnel inlet (wCSA) and the forearm (fCSA). SWE was performed on the MN in a longitudinal orientation at the wrist crease (wSWE), at the forearm (fSWE), and within the carpal tunnel (tSWE). Results: The wCSA and wSWE correlated positively with the neurophysiological severity of CTS (r =.619, P <.001; r =.582, P <.001, respectively). The optimal cut‐off values to discriminate the groups with normal NCS and with findings indicating CTS were 10.5 mm2 for the wCSA and 4.12 m/s for the wSWE. With these cut‐off values, wCSA had a sensitivity of 80% and specificity of 87% and wSWE a sensitivity of 88% and specificity of 76%. Neither tSWE nor fSWE correlated with the neurophysiological severity of CTS or differed between NCS negative and positive groups (P =.429, P =.736, respectively). Conclusion: Shear wave velocity in the MN at the carpal tunnel inlet increases in CTS and correlates to the neurophysiological CTS severity equivalently to CSA measured at the same site.

Longitudinal associations between signaled night awakening and executive functioning (EF) at 8 and 24 months in children with ([greater than or equal to] 3 awakenings, n = 77) and without parent-rated fragmented sleep ([less than or equal to] 1 awakening, n = 69) were studied. EF was assessed with the Switch task at 8 and 24 months. At 24 months, behavioral tasks and parental ratings of EF (Behavior Rating Inventory of Executive Function--Preschool version) were also used. In the Switch task, children with fragmented sleep were less able to learn stimulus sequences and inhibit previously learned responses than children without fragmented sleep. The groups differed only marginally in parental ratings of EF, and no differences were found in behavioral EF tasks. These results suggest that eye movement-based measures may reveal associations between sleep and EF already in infancy and toddlerhood.

Sustained autonomic arousal during eye contact could cause the impairments in eye contact behavior commonly seen in autism. The aim of the present study was to re-analyze the data from a study by Kaartinen et al. ("J Autism Develop Disord 42"(9):1917-1927, 2012) to investigate the habituation of autonomic arousal responses to repeated facial stimuli and the correlations between response habituation and social impairments among children with and without ASD. The results showed that among children with ASD, the smaller the habituation was, specifically in responses to a direct gaze, the more the child showed social impairments. The results imply that decreased autonomic arousal habituation to a direct gaze might play a role in the development of social impairments in autism.
