Long-term Outcomes After Autologous Hematopoietic Stem Cell Transplantation for Multiple Sclerosis.

Importance: Autologous hematopoietic stem cell transplantation (AHSCT) may be effective in aggressive forms of multiple sclerosis (MS) that fail to respond to standard therapies.

Objective: To evaluate the long-term outcomes in patients who underwent AHSCT for the treatment of MS in a large multicenter cohort.

Design, Setting, And Participants: Data were obtained in a multicenter, observational, retrospective cohort study.

Disobedience and driving in patients with epilepsy in Greece.

Objective: Regulations and guidelines regarding driving privileges of patients with epilepsy vary greatly worldwide. The aim of our study was twofold: firstly, to evaluate disobedient drivers in Greece and to elucidate their awareness of the law, emotional responses, and seizure profile and, secondly, to identify determinants of disobedience regarding driving among patients with epilepsy.

Methods: All consecutive patients with epilepsy who visited the epilepsy outpatient clinic of two tertiary epilepsy centers were invited to participate in the study.

Acute respiratory failure and sleep-disordered breathing in Arnold-Chiari malformation.

We report on the case of a 32-year-old man who was admitted after an episode of acute respiratory failure. Clinical and laboratory investigations revealed nocturnal hypoventilation with predominately obstructive sleep apneas accompanied by lower cranial nerve palsies, cerebellar and mild pyramidal signs. Magnetic resonance imaging disclosed Arnold-Chiari type I malformation with syringomyelia.

Stem cell transplantation for multiple sclerosis: what is the evidence?

Experimental and clinical observations have indicated that high-dose immunosuppression followed by autologous stem cell transplantation (ASCT) can induce remissions in severe, refractory, autoimmune diseases including multiple sclerosis (MS), a T cell-mediated autoimmune disorder against CNS myelin components, causing severe chronic disability. Control of the disease is unsatisfactory in most of the patients, especially those with rapidly evolving relapsing-remitting course and those with chronic progressive disease. The rationale for treating autoimmune diseases with ASCT is based on the immunosuppressive and immunomodulating effects of ASCT which may shift the immunological balance towards disease quiescence, a hypothesis supported by the results of ASCT in animal models of MS and by clinical observations in MS patients transplanted for concurrent malignancies.
