The prevalence and the burden of vincristine-induced neuropathy have been poorly documented in childhood acute lymphoblastic leukemia survivors. This cross-sectional study was carried out at a tertiary care center in northern India from October 2011 to June 2012. Eighty consecutive acute lymphoblastic leukemia survivors aged 5 to 18 years, within 3 years of completion of their chemotherapy, were enrolled. ⋯ The mean age at the time of evaluation was 11.2 ± 3.2 years. 33.75% had neuropathy electrophysiologically. Symmetric motor axonal polyneuropathy was the most common pattern of involvement seen in 19 (23.8%) children. There was significant improvement with time, as revealed by lower prevalence of neuropathy with increasing interval following vincristine injection. 33.75% of the children had Reduced version of Total Neuropathy Score ≥ 1.

Randomized Controlled Trial
Video diversion during fundoscopic examination in children: a randomized controlled trial.
Fundoscopy is an important aspect of a neurological examination but can be challenging in uncooperative children. This study explored whether viewing a video during examination improves the success, duration, and ease of pediatric fundoscopy. This single-practitioner, randomized study involved 60 patients aged 1 to 8 years. ⋯ Time needed to visualize the optic disc also improved (Δ16.3 s, P < .001). Improvement in the ease of examination (P < .001) was noted by both the practitioner and caregiver. This simple adjunct has the potential to improve the efficacy of this aspect of the pediatric neurological examination.

Tumefactive demyelinating lesions can be difficult to distinguish from tumors. Clinical and magnetic resonance imaging features of children with tumefactive demyelination and supratentorial brain tumors were compared. Patients were identified through a 23-site national demyelinating disease study, and from a single-site neuroradiology database. ⋯ Thirty-three children with tumors were identified. Children with tumefactive demyelination were more likely to have an abnormal neurologic examination and polyfocal neurologic deficits compared to children with tumors. Tumefactive demyelination was distinguished from tumor by the presence of multiple lesions, absence of cortical involvement, and decrease in lesion size or detection of new lesions on serial imaging.

To determine whether findings on videofluoroscopic swallow studies reveal different patterns of dysphagia between children with central and peripheral neurologic disorders, a retrospective study of 118 videofluoroscopic swallow studies was completed. There were 3 groups: cerebral palsy with only spastic features (n = 53), cerebral palsy with dyskinetic features (n = 34), and neuromuscular disorders (myotonic dystrophy I, n = 5; spinal muscular atrophy I-II, n = 8; Duchenne muscular dystrophy, n = 8; other neuromuscular disorder, n = 10). Interpretation of the videofluoroscopic swallow studies was not blinded. ⋯ In neuromuscular disorder, muscle weakness results in pharyngeal residue after swallow. The underlying swallowing problem in neuromuscular disorder is muscle weakness whereas that in cerebral palsy is more complex, having to do with abnormal control of swallowing. This study serves as a first exploration on specific characteristics of swallowing in different neurologic conditions and will help clinicians anticipate what they might expect.

Data were collected parenting stress, adaptive behavior, pain, and health issues from the caregivers of 35 girls and women with Rett syndrome (mean age = 20.3). A majority (60%) of parents reported stress in the clinical range on at least 1 subscale of the Parenting Stress Index-Short Form. ⋯ No other child factors (adaptive behavior, age, residential status) were significantly related to parenting stress. Factors related to chronic health concerns (seizures, ambiguous pain presentation) may be important when considering family stress issues in relation to general outcomes for girls with Rett syndrome and related developmental disorders.
