Variation in the leucine-rich repeat kinase 2 (LRRK2) gene represents the most common genetic determinant of Parkinson's disease (PD) identified to date. While the frequency and distribution of LRRK2 mutations have been well-studied in Europe and North America, few data are available from South America. To address this gap in knowledge, we screened two(More)
BACKGROUND Nasal congestion is the predominant symptom in perennial allergic rhinitis (PAR), and it seems to be mainly related to the late-phase inflammatory events. The present pilot study aimed to evaluate the therapeutic effect exerted by fexofenadine in patients with PAR due to mite allergy. METHODS This study was a parallel, double-blind, randomized,(More)
Mutations in the LRRK2 gene are the most common genetic cause of Parkinson's disease, with frequencies displaying a high degree of population-specificity. Although more than 100 coding substitutions have been identified, only seven have been proven to be highly penetrant pathogenic mutations. Studies however are lacking in non-white populations. Recently,(More)
BACKGROUND Multiple system atrophy (MSA) is an adult-onset and rapidly progressive, neurodegenerative condition that presents with autonomic dysfunction, parkinsonism, cerebellar ataxia and corticospinal deficits. Clinical, demographic and epidemiological data from different regions have provided valuable information concerning the natural history of MSA.(More)
BACKGROUND Rhinosinusitis represents one of the most common chronic diseases. The association of rhinosinusitis with asthma has been frequently reported. Eosinophils and Th2 cells play a pathogenic mechanism in asthma. OBJECTIVE The aims of the study were to evaluate the cytokine pattern in chronic rhinosinusitis in asthmatic children and to compare the(More)
BACKGROUND Despite the great attention that has been paid to HRQoL in children with respiratory allergy, few studies have addressed this aspect in relation to caregivers. The aim of our study was to evaluate the impact of childhood respiratory allergies on caregivers by means of a new method. METHODS 119 parents of children suffering from allergies (75(More)
INTRODUCTION Non-motor symptoms in Parkinson's disease are often not well recognized in clinical practice. Non-motor symptoms questionnaire (NMSQuest) is a simple instrument that allows patients or caregivers to report non-motor symptoms in a practical manner. OBJECTIVE We attempted to determine the prevalence of non-motor symptoms in three hundred(More)
