Portal Vein Dopplerflowmetry in healthy sheep according to age / Dopplerfluxometria da veia portal em ovinos hígidos de acordo com a idade

Pulsed Doppler ultrasound was used to evaluate portal blood flow, portal velocity and portal congestion index in 24 healthy sheep divided into groups (lambs, yearlings and ewes), according to age. Measurements were performed at the 11th right intercostal space using ideal insonation angle and uniform insonation method. Mean values obtained in each group were compared with one-way ANOVA, followed by Tukey post-hoc test. Portal velocity and portal blood flow were statistically similar between the groups (P>0.05). Mean portal velocity were 17.75; 17.13 and 16.75; while mean portal blood flow were 26.65; 31.04 and 24.32 for lambs, yearlings and ewes, respectively. Portal congestion index was statistically distinct between the groups and values for lambs, yearlings and ewes were 0.009; 0.058 and 0.09, respectively (P<0.01). Statistical differences were observed in portal vein diameter, portal vein area and portal congestion index between the groups, presumably due to influence of weight and not to age.(AU)

A ultrassonografia com Doppler pulsado foi utilizado para avaliar o fluxo sanguíneo portal, velocidade portal e índice de congestão portal em 24 ovinos saudáveis divididos em grupos (cordeiros, borregos e ovelhas), de acordo com a idade. As medições foram realizadas no 11o espaço intercostal direito utilizando ângulo de insonação ideal e método de inclusão uniforme. Os valores médios obtidos em cada grupo foram comparados com ANOVA, seguido pelo teste post-hoc de Tukey. A velocidade portal e o fluxo de sangue portal foram estatisticamente semelhantes entre os grupos (P>0,05). A velocidade portal média foram 17,75; 17,13 e 16,75; enquanto o fluxo de sangue portal médios foram 26,65; 31,04 e 24,32 para cordeiros, borregos e ovelhas, respectivamente. O índice de congestão portal foi estatisticamente diferente entre os grupos e os valores para cordeiros, novilhos e ovelhas foram 0,009; 0,058 e 0,09, respectivamente (P<0.01). Observaram-se diferenças estatísticas nos diâmetros da veia porta, na área da veia porta e nos índices de congestão portal entre os grupos, provavelmente devido à influência do peso e não pela idade.(AU)

Parasitas zoonóticos em fezes de cães em praças públicas do município de Itabuna, Bahia, Brasil / Zoonotic parasites in dog feces at public squares in the municipality of Itabuna, Bahia, Brazil

The contamination of public squares by zoonotic potential parasites was evaluated at the urban areas in the municipality of Itabuna Brasil. For such, 119 fecal samples of dogs were collected at 10 public squares. After that, these feces samples were transported to the Parasitology Laboratory in the UESC and they were analyzed by Mariano and Carvalho's method. Of the total analized samples, 56.3 percent show some parasitic evolutive form. Ancylostoma sp. was the most frequently (47.9 percent), followed by Strongyloides stercortalis (6.7 percent), Toxocara canis and Trichuris vulpis eggs (4.2 percent) each, Endolimax nana cysts (2.5 percent), and Giardia intestinalis and Entamoeba coli cysts (0.8 percent) each.

Avaliou-se a contaminação de praças públicas da área urbana do município de Itabuna, BA, Brasil, por parasitos zoonóticos presentes em fezes de cães. Foram coletadas 119 amostras fecais de cães em 10 praças. Logo após, estas fezes foram encaminhadas ao Laboratório de Parasitologia da UESC e analisadas pelo método de Mariano e Carvalho. Do total das amostras analisadas, 56,3 por cento continham alguma forma evolutiva parasitária, sendo o parasita mais freqüente Ancylostoma sp. com 47,9 por cento, seguido por 6,7 por cento de Strongyloides stercortalis, 4,2 por cento tanto para ovos de Toxocara canis quanto de Trichuris vulpis, 2,5 por cento para cistos de Endolimax nana, e 0,8 por cento tanto para cistos de Giardia intestinalis quanto para os de Entamoeba coli.

Hemophilia care in the state of Rio de Janeiro, Brazil

In the developing countries of the world, few people with hemophilia receive adequate care. Nevertheless, Brazil has made significant advances in the treatment of hemophilia over the last decade. The provision of factor concentrates imported by the Government of Brazil is gradually increasing, and patients receive the concentrates for free. A national register was established as well as a coordinated program for comprehensive care. Of the 6 297 persons with hemophilia in Brazil who were registered as of January 2001, 689 of them (11.1 percent) were registered in the state of Rio de Janeiro. Of those 689, 664 of them were being monitored at the state's coordinating blood transfusion center, which is located in the city of Rio de Janeiro. Among those 664, factor VIII inhibitors were identified in 81 of them (12.2 percent). Among 653 of the Rio de Janeiro patients who were tested for transfusion-transmitted diseases, the overall prevalence found was 41.5 percent, with the specific rates being 13.3 percent for human immunodeficiency virus (HIV), 2.9 percent for hepatitis B virus (HBV), and 39.4 percent for hepatitis C virus (HCV). The state of Rio de Janeiro has adopted a comprehensive hemophilia management approach that includes medical, psychological, and social care. As a result, the quality of life of hemophilia patients has improved noticeably. For example, the rate of hospitalization among patients fell by 30 percent between 1998 and 2001, and there has also been a decline in the school and work activities that they have missed
