Brazil Anticorpos anti-Brucella canis e anti-Brucella abortus em caes de Araguaina, Tocantins

The aims of the present study were to determine the seroprevalence of infection by Brucella canis and Brucella abortus and to evaluate possible risk factors for infection in dogs from Araguaina, Tocantins, Brazil. Sera from 374 dogs, of the urban zones of the municipality, from both sexes, were submitted to the agar-gel immunodiffusion for Brucella canisantibodies and to rose Bengal test (AAT) and fluorescence polarization assay (FPA) for Brucella abortus-antibodies. From the 374 tested dogs, 21 reacted in the AAT, but no one was positive in the FPA. The seroprevalence of B. canis infection found in Araguaina, Tocantins, Brazil, was 44.53% (95% IC; 39.43 to 49.72). No association was found among seropositivity for B. canis and the risk factors studied. Thus, data from the present study showed that there was no infection by B. abortus among dogs in the sample and that infection by B. canis is widespread and at high prevalence in Araguaina, Tocantins, Brazil.

Muscular strength, bone density and body composition of a woman with systemic lupus erythematosus submitted to a resistance training program: A case report

Introduction. Physical activity can provide long-term benefits for systemic lupus erythematosus (SLE). Objective. This study sought to demonstrate the effects of progressive resistance training on the muscular strength, bone mineral density (BMD) and body composition of pre-menopausal women with SLE undergoing glucocorticoid (GC) treatment. Materials and Methods. This is the case report of a 43-year-old African-South American premenopausal woman with non-extensive SLE and low bone density. A six-month program with three bimonthly cycles of 70%, 80%, and 90% intensity according to the 10 maximum-repetition test was used. Dual-energy X-ray absorptiometry (DXA) was used to measure the BMD, T-scores and body composition, and indirect fluorescence was used to measure the levels of antinuclear antibodies. Student's t-test was used. Results. Statistical improvement was noted in all strength exercises, including the 45° leg press (Δ%=+50%, p<0.001) and knee extension (Δ%=+15%, p=0.003) to maintain the BMD of the L2-L4 lumbar (Δ%=+0.031%; p=0.46) as well as the trochanter (Δ%=+0.037%; p=0.31) and BMI (Δ%=-0.8, p=0.54). Conclusion. In this case study, the presented methodology had a positive effect on strength and contributed to the maintenance of BMD and body composition in a woman with SLE undergoing GC treatment. © 2012 Revista Andaluza de Medicina del Deporte.

Validation of the portuguese simple measure of impact of lupus erythematosus in youngsters (SMILEY) in Brazil

Background and Objective: Simple Measure of the Impact of Lupus Erythematosus in Youngsters (SMILEY) is a health-related quality of life (HRQOL) assessment tool for pediatric systemic lupus erythematosus (SLE), which has been translated into Portuguese for Brazil. We are reporting preliminary data on cross-cultural validation and reliability of SMILEY in Portuguese (Brazil). Methods: In this multi-center cross-sectional study, Brazilian children and adolescents 5-18 years of age with SLE and parents participated. Children and parents completed child and parent reports of Portuguese SMILEY and Portuguese Pediatric Quality of Life Inventory (PedsQLTM) Generic and Rheumatology modules. Parents also completed the Childhood Health Assessment Questionnaire (CHAQ). Physicians completed the SLE disease activity index (SLEDAI), Physician's Global Assessment of disease activity (PGA) and Systemic Lupus Erythematosus International Collaborating Clinics ACR Damage Index (SDI). Results: 99 subjects (84 girls) were enrolled; 93 children and 97 parents filled out the SMILEY scale. Subjects found SMILEY relevant and easy to understand and completed SMILEY in 5-15 minutes. Brazilian SMILEY was found to have good psychometric properties (validity and reliability), and the child-parent agreement was moderate. Conclusion: SMILEY may eventually be used routinely as a research/clinical tool in Brazil. It may be also adapted for other Portuguese-speaking nations offering critical information regarding the effect of SLE on HRQOL for children with SLE. © The Author(s), 2012.

Increase nitric oxide and oxidative stress in dogs experimentally infected by Ehrlichia canis: Effect on the pathogenesis of the disease

The aim of this study was to evaluate nitric oxide levels, lipid peroxidation, protein oxidation and glutathione reductase activity in serum of dogs experimentally infected by Ehrlichia canis. Banked serum samples of dogs divided into two groups were used: negative control (n=5) and infected by E. canis (n=5). The concentration of nitrite/nitrate (NOx), lipid peroxidation (TBARS), advanced oxidation protein products (AOPP), and glutathione reductase (GR) activity in sera were evaluated. Samples were collected on days 0, 3, 6, 18 and 30 post-infection (PI). NOx and TBARS levels were significantly (P<0.05) higher in the infected group at 18 and 30 days PI, as well as AOPP levels at 30 days PI when compared to samples from control group. The GR activity was significant (P<0.05) increased in serum of dogs infected by E. canis on days 18 and 30 PI. Based on the increased levels of NOx, TBARS, AOPP and GR activity we concluded that dogs experimentally infected by E. canis develop a state of redox imbalance and that these changes might be involved in the pathophysiology of the disease. © 2013 Elsevier B.V.

Long-term cardiac changes in patients with systemic lupus erythematosus

Background: The aim of this study was evaluate the late-onset repercussions of heart alterations of patients with systemic lupus erythematosus (SLE) after a 13-year follow up. Methods. A historical prospective study was carried out involving the analysis of data from the charts of patients with a confirmed diagnosis of lupus in follow up since 1998. The 13-year evolution was systematically reviewed and tabulated to facilitate the interpretation of the data. Results: Forty-eight patient charts were analyzed. Mean patient age was 34.5 ± 10.8 years at the time of diagnosis and 41.0 ± 10.3 years at the time of the study (45 women and 3 men). Eight deaths occurred in the follow-up period (two due to heart problems). Among the alterations found on the complementary exams, 46.2% of cases demonstrated worsening at reevaluation and four patients required a heart catheterization. In these cases, coronary angioplasty was performed due to the severity of the obstructions and one case required a further catheterization, culminating in the need for surgical myocardial revascularization. Conclusion: The analysis demonstrated progressive heart impairment, with high rates of alterations on conventional complementary exams, including the need for angioplasty or revascularization surgery in four patients. These findings indicate the need for rigorous cardiac follow up in patients with systemic lupus erythematosus. © 2013 de Godoy et al.; licensee BioMed Central Ltd.

Craniometria em cães (Canis familiaris). Aspectos em crânios mesaticéfalos

In this study, a total of 25 skulls of the adult, mongrel and mesaticephalics dogs were used. Craniometric measurements for different parts of the skull were made. Cephalic indices and ratios were calculated. Certain points and landmarks on the skull are recognized in making linear measurements and are inion, bregma, nasion, prosthion, pogonion, basion, euryon, and zygion. Skull height (41,92 mm ± 3,9), skull length (177,72 mm ± 16,22), neurocranium (96,84 mm ± 7,25), viscerocranial (79,24 mm ± 8,72), basal length (140,24 mm ± 12,21), condylobasal (149,32 mm ± 12,21), snout (69,84 mm ± 7,07), nasals (50,08 mm ± 6,77), mandibular (129,88 mm ± 16,3), and of palatal (76,84 mm ± 7,01); width of neurocranium (62,24 mm ± 3,8), and zygomatic (95,44 mm ± 7,85) were obtained. Therefore, were calculated cranial index (53,83 mm ± 3,36), neurocranium (64,48 mm ± 4,69), facial (121,06 mm ± 9,18), basal (44,64 mm ± 4,17), width of the jugular processes (41 mm ± 4,2), of occipital condyles (35,48 mm ± 3,21), and of the foramen magnum (17,48 mm ± 2,27); height of the occipital triangle (38,28 mm ± 3,35), of the foramen magnum (14,36 mm ± 1,07); length of the dorsal notch (16,1 mm ± 1,12), and foramen magnum index (83,71 mm ± 14,44). Although with some differences in measurements, no significant difference was observed between the dimensions and reported to mesaticephalic skulls.
