RESUMO As úlceras colagenolíticas, também chamadas úlceras em Melting, úlceras de liquefação, ou ainda ceratomalácia, constituem uma alteração grave da córnea, com necessidade de intervenção rápida e agressiva, com alto risco de perda permanente da visão ou ruptura do globo ocular. São resultantes de uma destruição progressiva do estroma corneal, acarretando em fragmentação do colágeno, com liquefação e necrose da córnea. O presente estudo de caso relata a úlcera de córnea colagenolítica difusa em cão da raça Shih Tzu, a qual teve como tratamento cirúrgico o recobrimento corneal com flap simples de terceira pálpebra, com fixação palpebral, além da utilização de antibióticos, cicloplégicos e inibidor de proteases tópicos. Mesmo este não sendo a técnica cirúrgica de eleição preconizada na literatura, alcançou o sucesso terapêutico devido à progressiva recuperação da visão do paciente. PALAVRAS-CHAVE: afecção oftálmica, ceratomalácia, emergência oftálmica.

Atualmente Médicos Veterinários atendem a animais de companhia, animais não convencionais e animais de produção, sendo desta forma, necessária a atualização e aprofundamento de seus conhecimentos para acompanhar o crescimento. A obtenção de conhecimento se inicia na faculdade com as práticas de ensino e se estende a vida profissional, através de especializações, pós-graduações e leitura de artigos, com esta visão foi compilado as pesquisas neste segundo volume de Estudos em Medicina Veterinária com temas inovadores dentro da clínica médica, nutrição, produtos de origem animal e práticas de ensino.

Introduction: The prevalence of dental anxiety appears to be relatively consistent throughout the world, but some studies reports higher levels than others. This may be related to different instruments used. Objective: to identify and describe the main instruments used in the assessment of dental anxiety in adolescents. Material and Methods: Literature review. Original studies involving adolescents, in which the methodology comprised the application of some instrument to identify and / or quantify the phenomenon, were included. The search was limited to English, Portuguese and Spanish publications in the period between 2012 and 2016. Reviews, Meta-analyzes and case reports were excluded. The selected databases were MEDLINE (via PubMed) and LILACS (via BVS); and the search was developed with the following descriptors: 'dental anxiety', 'adolescents', 'Surveys and Questionnaires' (MeSH), combined by the Boolean operator AND. Results: Ten psychometric instruments are available to assess dental anxiety. The most frequently used instrument is the Dental Anxiety Scale (DAS), presented in nine studies. Less frequently used is the Facial Image Scale (FIS), presented in only one investigation. Most of the instruments affords translations into other languages, including Portuguese. Conclusion: The most used instrument is the DAS, followed by its modified version, the MDAS. Usually, more than one instrument has been used to correlate the findings and to provide the measured construct a greater consistency.Descriptors: Dental Anxiety; Adolescent; Surveys and Questionnaires.ReferencesStenebrand A, Wide Boman U, Hakeberg M.
