Objective: To evaluate sleepiness and central hypersomnia in multiple sclerosis (MS)-associated fatigue, we performed long-term polysomnography in patients with MS and healthy controls.

Methods: Patients with MS and healthy controls completed questionnaires on sleep, fatigue, sleepiness, and depression. They underwent nocturnal polysomnography, multiple sleep latency tests, and bed rest 24-hour polysomnography.

Aims: Lower urinary tract dysfunctions (LUTD) are very common in Multiple Sclerosis (MS), have a significant social impact, while the organic impact is discussed. We studied urinary complications and their risk factors in our cohort of MS patients, in order to improve the management of LUTD in MS.

Methods: Between 2004 and 2009, all patients affected by MS and managed for LUTD were included in a retrospective study.

Background: The Control Preference Scale (CPS) is the most frequently used measure of patients' preferred roles in treatment decisions. We revised the original CPS and developed a new computerized patient self-administered version (eCPS). We used the eCPS to assess role preferences, and their determinants, in Italian and German people with multiple sclerosis (MS).

Article Synopsis
  • The study investigated central and peripheral tolerance in relapsing-remitting multiple sclerosis patients, comparing those treated with IFN-beta to untreated individuals.
  • TREC-positive T cells were found to be lower in patients, especially in the CD4+ subgroup, suggesting issues with thymus function or increased peripheral lymphocyte expansion.
  • While IFN-beta treatment did not change TREC-positive cell counts or naive/memory T cell ratios, it was associated with lower overall blood lymphocyte counts and a decreased frequency of the CD4+CD45RC(high) subset.

The heterozygous R445H mutation in OPA1 was found in five patients with optic atrophy and deafness. Audiometry suggested that the sensorineural deafness resulted from auditory neuropathy. Skin fibroblasts showed hyperfragmentation of the mitochondrial network, decreased mitochondrial membrane potential, and adenosine triphosphate synthesis defect.
