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. The diagnoses of SS-CNS were made seven months to 30 years after the disease onset., Conclusion: SS-CNS is a rare disease that may remain undiagnosed for long periods. Awareness of this condition is essential for the clinician.

Objective: Vitamin D has taken center stage in research and treatment of multiple sclerosis (MS). The objective of the present study was to assess the serum vitamin D levels of a large population of patients with MS and controls living in a restricted tropical area., Methods: Data from 535 patients with MS and 350 control subjects were obtained from 14 cities around the Tropic of Capricorn., Results: The mean serum 25-OH vitamin D level was 26.07 ± 10.27 ng/mL for the control subjects, and 28.03 ± 12.19 ng/mL for patients with MS. No correlation was observed between vitamin D levels and the disability of patients over the disease duration., Conclusion: At least for the region around the Tropic of Capricorn, serum levels of vitamin D typically are within the range of 20 to 30 ng/mL for controls and patients with MS.

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. The patients had good disease control and no adverse events were reported., Conclusion: Washout may not be necessary in daily practice when switching from natalizumab to fingolimod. Expertise on multiple sclerosis management, however, is essential for drug switching.

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., Methods: Retrospective data on patients with arterial dissection related to sports and recreation., Results: Forty-one cases were identified. The most frequently affected vessel was the vertebral artery. A large variety of activities had a temporal relationship to arterial dissection, and jogging was the most frequent of these. This is the largest case series in the literature., Conclusion: Arterial dissection may be a complication from practicing sports.

Objective: The study aims to investigate the presence of pain amongst multiple sclerosis (MS) patients., Method: One hundred MS patients responded to questionnaires evaluating neuropathic and nociceptive pain, depression and anxiety. Statistical analysis was performed using the Mann-Whitney U, Chi-Square and two-tailed Fisher's exact tests and multivariate logistic regression., Results: Women had a statistically higher prevalence of pain (p = 0.037), and chances of having pain after the age of 50 reduced. Women with pain had a statistically significant lower number of relapses (p = 0.003), restricting analysis to those patients with more than one relapse. After the second relapse, each relapse reduced the chance of having pain by 46%. Presence of pain was independent of Expanded Disability Status Scale (EDSS) anxiety, and depression., Conclusion: Our findings suggest a strong inverse association between relapses and pain indicating a possible protective role of focal inflammation in the control of pain.

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. The rate of bradycardia in these patients was higher than that observed in clinical trials with very strict inclusion criteria for patients. There were less than 10% of cases requiring special attention, but no fatal cases. All but one patient continued the treatment after this initial dose. This is the first report on real-life administration of fingolimod to Brazilian patients with MS, and one of the few studies with these characteristics in the world.

Objective: To describe the etiologies of West syndrome (WS) among children followed in a rehabilitation center., Method: Retrospective study with emphasis in the following items: gender, age at the diagnosis of WS and its etiology. The etiologies were divided into three categories: symptomatic, cryptogenic and idiopathic. Symptomatic cases were classified as follows: pre, post and perinatal., Results: Ninety-five patients were included. Fifty-nine were boys (62%). Mean age at the diagnosis was 4.9 (+/- 5.0) months. There were 25 cryptogenic (26.3%), one idiopathic (1.1%) and 69 (72.6%) symptomatic cases, most of them of perinatal origin., Conclusion: Our findings are in agreement with the literature. In the future, as our knowledge in the field of WS and its diagnostic methods increase, there will be a small number of cryptogenic and idiopathic cases.

We report a case of a 18-year-old female patient that developed a migraine-like headache following an acute meningococcal meningitis. She had no previous history of recurrent headaches. The pain was intense, pulsatile and throbbing, typically unilateral, without aura. Its frequency increased during the following weeks and a prophylactic treatment with amitriptyline and atenolol was initiated. There was remission of the attacks.

Congenital muscle dystrophy (CMD) is a heterogeneous group of autosomal recessive myopathies. It is known that CMD may affect the central nervous system (CNS). Some authors have shown that merosin-negative CMD patients may have encephalic metabolic disturbances. In order to study metabolic changes within the brain, the authors performed a magnetic resonance spectroscopy (MRS) study in a 1-year-old girl with merosin-positive CMD (MP-CMD). MRS of brain demonstrated that NAA/Cr ratio was decreased (1.52), while Cho/Cr ratio was increased (1.78). These findings suggest that metabolic changes in CNS can also be found in patients with MP-CMD.

Hypomyelination with atrophy of the basal ganglia and cerebellum (H-ABC) is a rare disease that has been recently described. It must be remembered as a possible etiology of leukoencephalopathies in children. We describe a typical case of H-ABC in a 11-month-old boy. He presents with global development delay, oral dyskinesia, and global dystonia and spasticity. Magnetic resonance imaging disclosed typical features of H-ABC and clinical laboratory tests were all negative. A slow neurological deterioration has been detected with worsening of involuntary movements.

A case series study of 50 consecutive patients with episodic tension type headache (ETTH) was conducted. Clinical aspects, family history and impact on work activities were studied. The casuistry was made up of 40 women and 10 men. The average age was 30 (+/-12) years. Constrictive pain was present in 40 patients (80%). Sickness was the most commonly reported related phenomenon (20%). As expected, bilateral pain predominated; however, unilateral location was also present (10%). Although classically described as a mild pain, we observed that ETTH can come in intense crisis (16%). Family history of tension type headache was positive in 12 patients. The impact on work activities was substantial (14%). Our findings regarding to clinical aspects are in agreement with the literature. It is important to mention that the impact of ETTH on the individual and society should be reconsidered, and is more substantial than has been reported to date.

Background: Tension-type headache (TTH) is recognized as the most prevalent type of headache. Despite this, there is a limited understanding of the entity's physiology, epidemiology, and clinical presentation. Anxiety and depression are recognized comorbidities present among patients with TTH., Objective: To quantify the prevalence of anxiety and depression among patients with episodic and chronic TTH., Method: fifty patients with episodic TTH and fifty patients with chronic TTH completed Beck's anxiety and depression surveys. Only patients presenting with moderate to severe scores were considered., Results: among the patients with episodic TTH, anxiety and depression were observed in 30 (60%) and 16 (32%) patients respectively. Among the patients with chronic TTH, anxiety was observed in 22 (44%) patients, and depression was observed in 20 (40%)., Conclusion: both comorbidities are important among patients with episodic and chronic TTH. Neglecting this association may result in failure of symptomatic and prophylactic treatment ultimately leading to lost quality of life.
