Comparison of the effect of nocturnal use of commercial versus custom-made wrist orthoses, in addition to gliding exercises, in the function and symptoms of carpal tunnel syndrome: A pilot randomized trial.

Background: Conservative treatment for carpal tunnel syndrome (CTS) often includes wrist orthosis. However, there is no consensus on whether commercial or custom-made wrist orthosis is better for the treatment.

Purpose: To assess feasibility of a study comparing nocturnal use of commercial versus custom-made wrist orthosis in the treatment of mild/moderate CTS and estimate their potential effects on function and symptoms.

Alice in Wonderland syndrome: "Who in the world am I?".

Alice in Wonderland syndrome (AIWS) is a paroxysmal, perceptual, visual and somesthetic disorder that can be found in patients with migraine, epilepsy, cerebrovascular disease or infections. The condition is relatively rare and unique in its hallucinatory characteristics. OBJECTIVE To discuss the potential pathways involved in AIWS.

Serological profile of John Cunningham virus (JCV) in patients with multiple sclerosis.

Unlabelled: Treatment options for multiple sclerosis (MS) have changed over the last few years, bringing about a new category of drugs with more efficient profiles. However, these drugs have come with a whole new profile of potential adverse events that neurologists have to learn well and quickly. One of the most feared complications of these MS treatments is progressive multifocal leukoencephalopathy caused by the reactivation of the John Cunningham virus (JCV).

Critical analysis on the present methods for brain volume measurements in multiple sclerosis.

Objective: The treatment of multiple sclerosis (MS) has quickly evolved from a time when controlling clinical relapses would suffice, to the present day, when complete disease control is expected. Measurement of brain volume is still at an early stage to be indicative of therapeutic decisions in MS.

Methods: This paper provides a critical review of potential biases and artifacts in brain measurement in the follow-up of patients with MS.

Superficial siderosis of the central nervous system is a rare and possibly underdiagnosed disorder.

Methods: Series of cases collected from Brazilian centers.

Results: We studied 13 cases of patients presenting with progressive histories of neurological dysfunction caused by SS-CNS. The most frequent clinical findings in these patients were progressive gait ataxia, hearing loss, hyperreflexia and cognitive dysfunction.

Safety of switching from natalizumab straight into fingolimod in a group of JCV-positive patients with multiple sclerosis.

Objective: To assess safety of the switch between natalizumab and fingolimod without a washout period.

Methods: Prospective data on 25 JCV positive patients who underwent this medication switch were collected and analyzed.

Results: After a median period of nine months from the medication switch, there were no safety issues to report.

Real-life experience with fampridine (Fampyra®) for patients with multiple sclerosis and gait disorders.

Background: Fampridine is a broad-spectrum voltage-dependent potassium channel blocker that enhances synaptic transmission. The drug has been shown to be able to ameliorate conduction in demyelinated axons, thereby leading to improved gait in patients with multiple sclerosis (MS).

Objective: To assess the "real-life" efficacy and safety of fampridine prescribed for gait disorders in MS.

Alternatives for reducing relapse rate when switching from natalizumab to fingolimod in multiple sclerosis.

Natalizumab is a therapeutic option for treating multiple sclerosis (MS) and is particularly efficacious for patients with highly active disease. A long washout period has been recommended between withdrawal of natalizumab and start of fingolimod (another option for treating MS). This long washout period has been associated with a significant increase in MS activity.

Cerebrum-cervical arterial dissection in adults during sports and recreation.

Unlabelled: Dissection of cervical arteries constitutes a medical emergency. Although relatively rarely, activities classified as sports and recreation may be a cause of arterial dissection independently of neck or head trauma. The purpose of the present paper was to present a series of cases of cerebrum-cervical arterial dissection in individuals during or soon after the practice of these sports activities.

Central Nervous System Idiopathic Inflammatory Demyelinating Disorders in South Americans: A Descriptive, Multicenter, Cross-Sectional Study.

The idiopathic inflammatory demyelinating disease (IIDD) spectrum has been investigated among different populations, and the results have indicated a low relative frequency of neuromyelitis optica (NMO) among multiple sclerosis (MS) cases in whites (1.2%-1.5%), increasing in Mestizos (8%) and Africans (15.

Leflunomide and teriflunomide: altering the metabolism of pyrimidines for the treatment of autoimmune diseases.

Leflunomide modulates T-cell responses and induces a shift from the Th1 to Th2 subpopulation. This process results in a beneficial effect in diseases in which there is good evidence that T cells play a major role in both initiation and perpetuation of the inflammatory condition. Leflunomide has been successfully used for treating rheumatoid arthritis and psoriatic arthritis for many years.

The real-life experience with cardiovascular complications in the first dose of fingolimod for multiple sclerosis.

Fingolimod is a new and efficient treatment for multiple sclerosis (MS). The drug administration requires special attention to the first dose, since cardiovascular adverse events can be observed during the initial six hours of fingolimod ingestion. The present study consisted of a review of cardiovascular data on 180 patients with MS receiving the first dose of fingolimod.

How do we manage and treat a patient with multiple sclerosis at risk of tuberculosis?

Tuberculosis continues to be a serious health problem worldwide. The disease continues to be underdiagnosed and not properly treated. In conditions that affect the immune system, such as multiple sclerosis (MS), latent tuberculosis may thrive and reactivate during the use of immunomodulatory and immunosuppressive drugs.

There is still a role for the blink reflex in the diagnosis and follow-up of multiple sclerosis.

Objective: The evolution of the diagnostic criteria for multiple sclerosis (MS) has essentially evolved to clinical manifestations and magnetic resonance imaging. Inexpensive, quick to apply, non-invasive, quantitative and reliable neurophysiological tests are rare in daily practice and absent in clinical trials.

Method: The blink reflex was assessed in 50 patients with remitting-relapsing MS (RRMS) and 100 matched controls.

Postpartum Treatment With Immunoglobulin Does Not Prevent Relapses of Multiple Sclerosis in the Mother.

Multiple sclerosis (MS) is a chronic, neurological, immune-mediated disease that can worsen in the postpartum period. There is no consensus on the use of immunoglobulin for prevention of disease relapses after delivery. We have shown that the controversial beneficial effect of immunoglobulin given immediately after birth could not be observed in patients with MS.

The blink reflex test does not show abnormalities in a large group of patients with chronic migraine.

Unlabelled: The blink reflex - a simple, non-invasive and inexpensive test - may be indicative of lesions or dysfunctions of the brainstem, and particularly assesses the trigeminal-facial arch. Results from alterations of the blink reflex in patients with headaches have provided controversial data.

Method: Registration of the waves R1 and R2 (ipsilateral to the stimulus) and R2c (contralateral to the stimulus) by electroneuromyography.

Multiple sclerosis in South America: month of birth in different latitudes does not seem to interfere with the prevalence or progression of the disease.

Objective: To assess whether the month of birth in different latitudes of South America might influence the presence or severity of multiple sclerosis (MS) later in life.

Methods: Neurologists in four South American countries working at MS units collected data on their patients' month of birth, gender, age, and disease progression.

Results: Analysis of data from 1207 MS patients and 1207 control subjects did not show any significant variation in the month of birth regarding the prevalence of MS in four latitude bands (0-10; 11-20; 21-30; and 31-40 degrees).
