| genomic characterization of wild-type measles viruses that circulated in different states in brazil during the 1997 measles epidemic. | despite the marked reduction in the incidence of measles in brazil, a measles epidemic occurred in this country in 1997. the measles cases observed during this epidemic began to reappear in large numbers in são paulo, and spread to rio de janeiro and other brazilian states. in the present study molecular biology techniques were used for the detection and genomic characterization of measles viruses from clinical samples such as urine and nasopharyngeal secretions collected in the states of rio de ... | 2001 | 11241461 |
| trans-cultural aspects of obsessive-compulsive disorder: a description of a brazilian sample and a systematic review of international clinical studies. | little is known about the extent and the mechanisms through which culture may affect the clinical manifestations of obsessive-compulsive disorder (ocd). in this study, our objective was to identify culture-related symptomatological patterns in ocd. we described the socio-demographic and phenomenological characteristics of 101 adult patients with ocd seen at an university clinic for anxiety and depressive disorders in rio de janeiro, brazil, and compared them with those reported in 15 clinical sa ... | 2004 | 15203292 |
| use of rt-pcr on oral fluid samples to assist the identification of measles cases during an outbreak. | this study investigated the occurrence of mild modified measles cases during an outbreak in niterói, rj, brazil by using rt-pcr on oral fluid samples. from august to december 1997 a total of 76 patients with rash were seen at the study sites. confirmed diagnosis by serology was achieved in 47 cases: measles (39.5%), rubella (13.2%), hhv-6 (3.9%), human parvovirus b19 (3.9%), dengue fever (3%). for 19 of the 29 patients without a conclusive diagnosis paired serum and saliva samples were available ... | 2003 | 12613751 |
| attention-deficit/hyperactivity disorder and comorbidity in brazil: comparisons between two referred samples. | the aim of this study was to compare the pattern of comorbidity in referred samples of attention-deficit/hyperactivity disorder (adhd) patients from two different geographic areas in brazil. | 2004 | 15365895 |
| sporothrix schenckii isolated from domestic cats with and without sporotrichosis in rio de janeiro, brazil. | a total of 148 cats with a clinical and mycologic diagnosis of sporotrichosis and 84 apparently healthy cats with domiciliary contact with the affected animals were studied. sporothrix schenckii was isolated from 148 (n = 148; 100%) clinical samples of cutaneous lesion (biopsy, swab or aspiration of purulent secretion), 47 (n = 71; 66.2%) nasal cavities, 33 (n = 79; 41.8%) oral cavities, and 15 (n = 38; 39.5%) nails of cats with sporotrichosis. histopathological examination revealed yeast-like s ... | 2002 | 12000130 |
| the genomic analysis of rubella virus detected from outbreak and sporadic cases in rio de janeiro state, brazil. | the molecular epidemiology of rubella virus (rv) based on the analysis of the viral e1 gene sequences indicated the existence of two genotypes that differ from each other by 8 to 10% in their nucleotide sequences: genotype i is present in europe, north america and asia; and genotype ii is present only in asia. | 2003 | 12829043 |
| [prevalence of attention deficit hyperactivity disorder and its comorbidities in a sample of school-aged children]. | attention deficit hyperactivity disorder (adhd) is a frequent condition in school-age children and commonly presents in comorbidity with other psychiatric diseases. in brazil, there are few studies concerning non-clinical samples. | 2007 | 18094880 |
