Avaliação de medidas de controle de flebotomíneos

Realizou-se coletas de flebotomíneos de maio de 2005 a abril de 2006. Os resultados foram comparados com os das coletas realizadas entre abril de 2001 e setembro de 2002, para avaliar as medidas empregadas para diminuir a densidade destes insetos, no Recanto Marista, município de Doutor Camargo, Estado do Paraná. As coletas foram feitas com armadilhas de Falcão, em domicílios e galinheiros, das 22 às 2 horas, semanalmente, quatro vezes ao mês. Em 2005 e 2006, coletaram-se 213.195 flebotomíneos, 1.113,8 em média por hora (MH) e em 2001 e 2002, 199.821 (MH=1.653,5). Nyssomyia neivai prevaleceu (75,4%) em todos os ecótopos que, juntamente com Nyssomyia whitmani (23,4%), Migonemyia migonei (0,8%) e Pintomyia fischeri (0,4%), representaram 99,7% do total coletado. Nos ecótopos representados por galinheiros foram coletados 88,7% dos flebotomíneos. Constatou-se que houve queda na densidade de flebotomíneos no período de coletas 2005 e 2006 em relação à de 2001 e 2002, especialmente no domicílio.

Memória espacial e/ou olfativa em flebotomíneos em área endêmica de leishmaniose tegumentar americana, sul do Brasil

Relata-se os resultados de uma investigação sobre a possibilidade da existência de memória em flebotomíneos em área endêmica de leishmaniose tegumentar americana, no Estado do Paraná. Capturaram-se flebotomíneos no Recanto Marista, Doutor Camargo, Estado do Paraná, Brasil, com armadilhas de Falcão, de 15/11/2007 a 26/11/2007, em dois galinheiros (G1 e G2). Foram capturados 2.080 flebotomíneos (1.000 em G1 e 1.080 em G2), que foram marcados e soltos. Nyssomyia neivai foi a espécie mais (90,5%) freqüente. Do total solto, recapturaram-se 168 (8%) flebotomíneos e a recaptura no G2 foi significativa. Os resultados evidenciam que é possível a existência de memória espacial, olfativa e/ou a fidelidade ao hospedeiro e que isto orientem os flebotomíneos no reconhecimento dos locais onde há disponibilidade de fontes de sangue.

Sandfly frequency in a clean and well-organized rural environment in the state of Paraná, Brazil

INTRODUCTION: Sandflies caught in Santa Juliana Farm in Sarandi, State of Paraná, Brazil, were assessed in terms of their fauna, seasonality, and frequency in the homes and in shelters of domestic animals around the homes, as well as in the nearby forest. METHODS: In Santa Juliana Farm, there are no records of cases of ACL, differing from other relatively clean and organized areas where surveys of sandflies have been conducted in Paraná. Samples were collected with Falcão light traps, fortnightly from 22:00 to 02:00 hours, from November 2007 to November 2008. RESULTS: A total of 4,506 sandflies were captured, representing 13 species, predominantly Nyssomyia whitmani (71.8%). More sandflies were collected in the forest (52.6%) than outside the forest (residences and pigsty) (47.4%). However, Ny. whitmani was collected in greater numbers outside (38.3%) than inside the forest (33.5%). Most sandflies were collected in the warmer months and during periods with regular rainfall. CONCLUSIONS: The results suggest that cleaning and organization around the houses could reduce sandfly population in peridomicile. Constructing shelters for animal at a distance of approximately 100m from domiciles is recommended to prevent the invasion of sandflies, as this farm has an area of preserved forest, with wild animals and sandflies present to maintain the enzootic cycle of Leishmania.

Untersuchungen zur Funktion der Proteinkinase B (PKB/Akt) bei der Migration und Adhäsion von Maus-Lymphozyten

Kallikrein genes are associated with lupus and glomerular basement membrane-specific antibody-induced nephritis in mice and humans.

Immune-mediated nephritis contributes to disease in systemic lupus erythematosus, Goodpasture syndrome (caused by antibodies specific for glomerular basement membrane [anti-GBM antibodies]), and spontaneous lupus nephritis. Inbred mouse strains differ in susceptibility to anti-GBM antibody-induced and spontaneous lupus nephritis. This study sought to clarify the genetic and molecular factors that maybe responsible for enhanced immune-mediated renal disease in these models. When the kidneys of 3 mouse strains sensitive to anti-GBM antibody-induced nephritis were compared with those of 2 control strains using microarray analysis, one-fifth of the underexpressed genes belonged to the kallikrein gene family,which encodes serine esterases. Mouse strains that upregulated renal and urinary kallikreins exhibited less evidence of disease. Antagonizing the kallikrein pathway augmented disease, while agonists dampened the severity of anti-GBM antibody-induced nephritis. In addition, nephritis-sensitive mouse strains had kallikrein haplotypes that were distinct from those of control strains, including several regulatory polymorphisms,some of which were associated with functional consequences. Indeed, increased susceptibility to anti-GBM antibody-induced nephritis and spontaneous lupus nephritis was achieved by breeding mice with a genetic interval harboring the kallikrein genes onto a disease-resistant background. Finally, both human SLE and spontaneous lupus nephritis were found to be associated with kallikrein genes, particularly KLK1 and the KLK3 promoter, when DNA SNPs from independent cohorts of SLE patients and controls were compared. Collectively, these studies suggest that kallikreins are protective disease-associated genes in anti-GBM antibody-induced nephritis and lupus.

Appropriate management of special situations in Crohn's disease (upper gastro-intestinal; extra-intestinal manifestations; drug safety during pregnancy and breastfeeding): results of a multidisciplinary international expert panel-EPACT II

Introduction: High-grade evidence is lacking for most therapeutic decisions in Crohn's disease. Appropriateness criteria were developed for upper gastro-intestinal, extra-intestinal manifestations and drug safety during conception, pregnancy and breastfeeding in patients with Crohn's disease, to assist the physician in clinical decision making. Methods: The European Panel on the Appropriateness of Crohn's Disease Therapy (EPACT II), a multidisciplinary international European expert panel, rated clinical scenarios based on evidence from the published literature and panelists' own clinical expertise. Median ratings (on a 9-point scale) were stratified into three categories: appropriate (7-9), uncertain (4-6 with or without disagreement) and inappropriate (1-3). Experts were also asked to rank appropriate medications by priority. Results: Proton pump inhibitors, steroids, azathioprine/6-mercaptopurine and infliximab are appropriate for upper gastro-duodenal Crohn's disease; for stenosis, endoscopic balloon dilation is the first-tine therapy, although surgery is also appropriate. Ursodeoxycholic acid is the only appropriate treatment for primary sclerosing cholangitis. Infliximab is appropriate for Pyoderma gangrenosum, ankylosing spondylitis and uveitis, steroids for Pyoderma gangrenosum and ankylosing spondylitis, adalimumab for Pyoderma gangrenosum and ankylosing spondylitis, cyclosporine-A/tacrolimus for Pyoderma gangrenosum. Mesalamine, sulfasalazine, prednisone, azathioprine/6-mercaptopurine, ciprofloxacin, and probiotics, may be administered safety during pregnancy or for patients wishing to conceive, with the exception that mate patients considering conception should avoid sulfasalazine. Metronidazol is considered safe in the 2nd and 3rd trimesters whereas infliximab is rated safe in the 1st trimester but uncertain in the 2nd and 3rd trimesters. Methotrexate is always contraindicated at conception, during pregnancy or during breastfeeding, due to its known teratogenicity. Mesalamine, prednisone, probiotics and infliximab are considered safe during breastfeeding. Conclusion: EPACT II recommendations are freely available online (www.epact.ch). The validity of these criteria should now be tested by prospective evaluation. (C) 2009 European Crohn's and Colitis Organisation. Published by Elsevier B.V. All rights reserved.

A bovine model of a respiratory Parachlamydia acanthamoebae infection.

The aim of this study was to evaluate the pathogenicity of Parachlamydia (P.) acanthamoebae as a potential agent of lower respiratory tract disease in a bovine model of induced lung infection. Intrabronchial inoculation with P. acanthamoebae was performed in healthy calves aged 2-3 months using two challenge doses: 10(8) and 10(10) bacteria per animal. Controls received 10(8) heat-inactivated bacteria. Challenge with 10(8) viable Parachlamydia resulted in a mild degree of general indisposition, whereas 10(10) bacteria induced a more severe respiratory illness becoming apparent 1-2 days post inoculation (dpi), affecting 9/9 (100%) animals and lasting for 6 days. The extent of macroscopic pulmonary lesions was as high as 6.6 (6.0)% [median (range)] of lung tissue at 2-4 dpi and correlated with parachlamydial genomic copy numbers detected by PCR, and with bacterial load estimated by immunohistochemistry in lung tissue. Clinical outcome, acute phase reactants, pathological findings and bacterial load exhibited an initial dose-dependent effect on severity. Animals fully recovered from clinical signs of respiratory disease within 5 days. The bovine lung was shown to be moderately susceptible to P. acanthamoebae, exhibiting a transient pneumonic inflammation after intrabronchial challenge. Further studies are warranted to determine the precise pathophysiologic pathways of host-pathogen interaction.

Alandica

Samlingen med signum HB Saml. Alandica finns vid huvudbiblioteket och innehåller litteratur som på något sätt berör landskapet Åland, politiskt, naturvetenskapligt, socialt, historiskt, litterärt osv. Stommen till Alandica-samlingen kommer från det historiska bibliotek som statsarkivarie Reinhold Hausen samlade och donerade till akademibiblioteket. I Hausens stora historiska bibliotek ingick en omfattande specialsamling om Åland som han använde som underlag för sina bibliografier över Åland publicerade i samlingsverken Åland VI, VII, IX och X. Bibliografierna omfattar tiden ända fram till 1936. Av särskilt intresse i Hausens samling är det material som handlar om ålandsfrågan, speciellt kan nämnas talrika särtryck av artiklar i tidskrifter och övertryck från tidningar, även utländska. Utom katalogiserat material finns det också endel okatalogiserat småtryck. Samlingen Alandica har kontinuerligt vuxit genom bibliotekets friexemplarsrätt. En del material har kommit som gåvor, t.ex. material från Ålands lagting. Samlingen innehåller också administrativt material som inte enskilt katalogiseras, exempelvis Ålands författningssamling och olika årsberättelser, verksamhetsberättelser och budgeter. Biblioteket strävar efter att bevaka den utländska utgivningen av alandica och kompletterar samlingen genom inköp. Återvinning av material görs i databasen Alma med sökfunktionen Signum och söktermen HB Saml. Alandica. En kortkatalog med alandica tryckt mellan 1830 och 1979 är i det närmaste retrokatalogiserad till Alma.
