Veterinary allergy diagnosis: past, present and future perspectives

Fleas, several aeroallergens as well as many food allergens are the most common allergenic sources for animals and frequent cause of allergic reactions with different target organs such as skin, eyes, and respiratory or digestive systems. Allergy diagnosis needs to follow well-established guidelines under clinical and laboratory approaches. Since 1980 with the Hanifin & Rajka’s criteria for the diagnosis of atopic dermatitis (AD) in humans, successive proposals have been developed to identify atopic dermatitis in dogs. A consensual plan was first proposed by Willemse in 1986 undergoing several modifications in 1994. Prélaud and colleagues made important changes to the plan in 1998 and it was further adjusted by Favrot in 2009. In 2010, this plan was approved by the International Task Force on Canine Atopic Dermatitis (CAD). It was subjected in 2015 to minor updates with regard to therapeutic options. To improve diagnostic accuracy by integrating the basic knowledge on sensitization development and allergen nature and diversity, allergen sources and implicated molecular allergens for animals should be clearly identified. As well as in human medicine, this molecular epidemiology concept is essential for the veterinary allergy diagnosis in the near future, standing as the basis of a component-resolved diagnosis (CRD). Besides current pharma- cotherapy, it will be highly relevant to increase the efficiency of the avoidance measures and specific immunotherapy. Clinical guidelines will lead to at least 80 % of positive diagnosis of atopy, but newer laboratory methods in veterinary medicine aiming to a more precise diagnosis and a better integration of the clinical/laboratory diagnostic course are needed. Allergoms identification for animals, from different allergen sources proteoms should become a priority in veterinary allergology, in order to allow the intended CRD, which is essential to understand the cross-reaction phenomena, allowing a more precise and possibly effective component-resolved immunotherapy (CRIT). Further research has been carried out for a better understanding of the interaction between allergic clinical condition and immune pathophysiology. As well as in human medicine, a deeper knowledge of the molecular immunological mechanisms in veterinary allergy — with their specific allergen triggers — will also provide the veterinary allergist with the necessary information to act more efficiently in the future.

Avaliação do potencial reprodutivo de touros através do exame andrológico

Este trabalho refere-se às atividades do estágio de Mestrado Integrado em Medicina Veterinária, apresentando-se casuística no âmbito dos planos sanitários e atividade clínica acompanhados. Como tema para discussão optou-se pela avaliação de touros através do exame andrológico. Após revisão bibliográfica analisaram-se dados obtidos pela VetAl (2008- 2012) caracterizando a população dos touros de carne no Sul de Portugal. Dos 184 touros avaliados foram aprovados 72,28 %, aumentando a probabilidade de reprovação tendencialmente com idade. Em parâmetros reprodutivos importantes como perímetro testicular existe influência de: idade (p<0,001), raça (p<0,05) e Pontuação da Condição Corporal (PCC) (p<0,05). Encontraram-se correlações significativas entre parâmetros tais como perímetro testicular e idade (p<0,001; r=0,52), PCC e parâmetros seminais microscópicos (p<0,05) e dos vários parâmetros entre si. O exame andrológico é essencial para estimar o potencial reprodutivo dos touros e importa fomentar a sua realização em Portugal para melhorar os níveis de fertilidade e rentabilidade das explorações; Abstract Rating of bulls’ reproductive potential through breeding soundness evaluation This document reports the activities of the traineeship for the Master in Veterinary Medicine, including the presentation of the number of cases attended during herd health plans and clinical activity. The theme chosen for discussion was bull fertility through breeding soundness evaluation. Data obtained by Vetal (2008-2012) were analyzed, according to the state of the art, with the aim of characterizing beef bulls’ population in Southern Portugal. Out of 184 bulls evaluated, 72,28 % were approved, unsuccessful outcome apparently increases with age. Scrotal circumference was significantly influenced by: age (p<0,001), breed (p<0,05) and Body Condition Scoring (BCS) (p<0,05). Correlations were significant between scrotal circumference and age (p<0,001; r=0,52), between BCS and microscopic semen evaluation parameters (p<0,05) and between these semen evaluation parameters. The breeding soundness evaluation is essential to assess bulls’ reproductive potential and routine performance of this exam should be encouraged in Portugal to improve fertility and herd profitability.

Patologia e clínica de equinos

O presente relatório de conclusão do curso de Mestrado Integrado em Medicina Veterinária da Universidade de Évora, refere-se ao período de estágio curricular obrigatório que decorreu na Clínica Equifort, em Fortaleza, Brasil, na área Patologia e Clínica de Equinos. Numa primeira fase é feita uma descrição das atividades desenvolvidas onde se apresenta a casuística acompanhada durante o estágio, que inclui atividades em diversas áreas como medicina desportiva, clínica médica, clínica reprodutiva, clínica cirúrgica e clínica hospitalar. Numa segunda fase desenvolve-se uma monografia onde se caracterizam as lesões radiográficas de membros anteriores de cavalos de desporto, e por fim são apresentados cinco casos clínicos; ABSTRACT: EQUINE PATHOLOGY AND CLINICAL The present report refers to curricular internship, integrated on the master degree in veterinary medicine at the University of Évora, that took place at the Clinic Equifort in Fortaleza, Brazil, in the área of Equine Pathology and Clinical. Initially a description of the activities accompanied during the internship is given which includes activities in areas such as sports medicine, internal medicine, reprodution and surgery. In a second part a monograph is developd with the characterization of radiographic injuries in forelimbs of sport’s horses, and finally five clinical cases are presented.
