The molecular diagnosis of type 1 facioscapulohumeral muscular dystrophy (FSHD1) relies on the detection of a shortened D4Z4 array at the 4q35 locus. Until recently, the diagnosis of FSHD2 relied solely on the absence of a shortened D4Z4 allele in clinically affected patients. It is now established that most FSHD2 cases carry a heterozygous variant in the SMCHD1 gene.

Purpose/objective: This study examined (a) differences in demographic and injury-related characteristics following traumatic brain injury (TBI) between Native American and White individuals; (b) differences in community participation between Native American and White individuals with TBI at 1, 2, and 5 years after TBI; and (c) whether demographic or injury-related characteristics account for community participation disparities.

Research Method/design: A sample of 63 Native American individuals demographically matched to 63 White individuals (n = 126) was enrolled while on acute rehabilitation for moderate or severe TBI. Baseline demographic and injury-related characteristics were collected at this time and the Participation Assessment with Recombined Tools (PART-O) measure of community participation at 1, 2, and 5 years after TBI.

Mega scientific conferences increasingly suffer from the need for short and poster presentations without discussion. An alternative is to organize workshops in hotels large enough to accommodate all participants. This significantly increases the opportunities for constructive discussion during breakfasts, lunches, dinners and long evenings that can bring together experts of scientific and clinical sub-specialties and young fellows.

  • Vestibular Neuritis (VN) can cause a sudden imbalance in patients, and a study was conducted to determine factors that might influence recovery from this condition, focusing on both complete recovery and adjustment to the symptoms.
  • The study involved 40 patients who underwent various tests and assessments within a few days of symptom onset and again after about three months, categorizing them based on their test results and self-reported symptom scores.
  • Results indicated that cardiovascular risk factors were linked to poorer recovery outcomes, and while some vestibular tests normalized over time, many patients reported ongoing subjective symptoms despite objective recovery.

(1) Background: Surgery for Chiari I malformation (CMI) is indicated when typical clinic-radiological features (syringomyelia, exertional headaches, sleep apnea syndrome, and tetraparesis) are present. Sometimes, patients have atypical complaints suggestive of otolaryngological (ENT) involvement, and it is sometimes difficult for the neurosurgeon to determine if these complaints are related to the CMI. Our aim was to describe postural control patterns in children with CMI using computerized dynamic posturography.
