Fragoso,Yara Dadalti; Adoni,Tarso; Alves-Leon,Soniza Vieira; Apostolos-Pereira,Samira L.; Arruda,Walter Oleschko; Brooks,Joseph B. BidinABSTRACT 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...
Alternative option for osteogenesis imperfecta and trigeminal neuralgia
Ruschel,Leonardo Gilmone; Agnoletto,Guilherme José; Hunhevicz,Sonival Cândido; Almeida,Daniel Benzecry de; Arruda,Walter OleschkoSummary Osteogenesis imperfecta (OI) is a bone disorder that can lead to skull base deformities such as basilar invagination, which can cause compression of cranial nerves, including the trigeminal nerve. Trigeminal neuralgia in such cases remains a challenge, given distorted anatomy and deformities. We present an alternative option, consisting in cannulation of the foramen ovale and classical percutaneous trea...
The real-life experience with cardiovascular complications in the first dose of...
Fragoso,Yara Dadalti; Arruda,Christian Cardoso; Arruda,Walter Oleschko; Brooks,Joseph Bruno Bidin; Damasceno,AlfredoFingolimod 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 patie...

Fragoso,Yara Dadalti; Adoni,Tarso; Almeida,Sandra Maria Garcia de; Alves-Leon,Soniza Vieira; Arruda,Walter Oleschko; Barbagelata-Aguero,FiorellaObjective 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 s...

Fragoso,Yara Dadalti; Mendes,Maria Fernanda; Arruda,Walter Oleschko; Becker,Jefferson; Brooks,Joseph Bruno Bidin; Carvalho,Margarete de JesusObjective Natalizumab is a new and efficient treatment for multiple sclerosis (MS). The risk of developing progressive multifocal leukoencephalopathy (PML) during the use of this drug has created the need for better comprehension of JC virus (JCV) infection. The objective of the present study was to assess the prevalence of JCV-DNA in Brazilian patients using natalizumab. Method Qualitative detection of the JCV...
