Introduction/aims: Data regarding weight, height/length, and growth status of patients with spinal muscular atrophy (SMA) who have received only supportive care are limited. This cross-sectional study describes these measurements in patients with Type 1 and Types 2/3 SMA and compares them with reference values from typically developing children., Methods: Retrospective baseline data from three sites in the Pediatric Neuromuscular Clinical Research Network (Boston, New York, Philadelphia) were used. Descriptive statistics for weight, height/length, body mass index-for-age, as well as weight-for-length and absolute and relative deviations from reference values (ie, 50th percentile from World Health Organization/Centers for Disease Control growth charts) were calculated. Furthermore, growth status was reported., Results: A total of 91 genetically confirmed patients with SMA receiving optimal supportive care and without any disease-modifying treatment were stratified into Types 1 (n = 28) and 2/3 SMA (n = 63). Patients with Type 1 SMA weighed significantly less (median = -7.5%) compared with reference values and patients with Types 2/3 SMA were significantly shorter (mean = -3.0%) compared with reference values. The median weight was considerably below the 50th percentile in both groups of patients, even if they received a high standard of care and proactive feeding support., Discussion: More research is needed to understand which factors influence growth longitudinally, and how to accurately capture growth in patients with SMA. Further research should investigate the best time to provide feeding support to avoid underweight, especially in patients with Type 1, and how to avoid the risk of overfeeding, especially in patients with Types 2/3 SMA., (© 2022 F.

Introduction: The influence of cold temperatures on neuropathies has been reported previously, but its impact on carpal tunnel syndrome (CTS) is not well analyzed., Methods: We analyzed the frequency of CTS among neurophysiological evaluations according to seasonal variation in 9574 consecutive patients (4260 with CTS)., Results: A higher frequency of CTS was found in the winter (50.8%), and the lowest number for CTS diagnosis was found in the summer (38.9%). In both autumn and spring the prevalence remained stable at an intermediate level between summer and winter at 42.8% and 43.5%, respectively., Conclusion: CTS frequency was much higher in winter in this center., (Copyright © 2012 Wiley Periodicals, Inc.)
