Summary Osteochondromas in the horse are most commonly found as a solitary lesion affecting the distal radial metaphysis. In this location, diagnosis is reliant on radiographic and ultrasonographic examination and confirmed with post‐operative histopathology. This case report describes the additional benefit of performing a CT arthrogram to aid the diagnosis of an osteochondroma in an atypical location.

Background: Synovial sepsis is a frequent cause of morbidity and mortality in horses.Despite advances in diagnostics and treatments, persistent infection or chronic lameness can occur. Objectives:To perform a scoping review to identify and evaluate the current evidence on the factors implicated in the success of treatment for synovial sepsis. Study design: Joanna Briggs Institute scoping review. Methods: A protocol was registered, and a systematic literature search was performed on CAB abstracts, Medline, Scopus and Embase. Inclusion and exclusion criteria were developed and studies systematically reviewed against this. Studies relating to factors affecting treatment success following synovial sepsis were retained and data was extracted on study method, population characteristics and factors significantly associated with treatment outcome. Results: In total, 2338 studies were identified, and 61 were included to full paper analysis. Eight papers reported significant factors, identifying 15 risk factors associated with two measurements of outcome, either survival and/or return to athletic function. The 15 factors were identified and categorised into pre-, intra-and post-operative factors.Risk factors that were identified included the number or type of synovial structures involved, the presence of pannus, tendon and bone pathology, and the use of systemic antimicrobials. There were many discrepancies in inclusion criteria of cases of synovial sepsis as well as measurement and description of outcome variables. Main limitations:Non-English language studies or conference proceedings were not included. Only small numbers of papers had similar findings. Conclusions: Standardisation of inclusion criteria is essential to enable comparisonsand analysis between studies on synovial sepsis. Future studies should use methodologies to reduce bias including multicentre and multinational studies, prospective study design and robust statistical modelling.

As vias de comunicação presentes entre o tecido pulpar e o tecido periodontal podem permitir inflamações e/ou infecções o que facilita o trânsito de bactérias entre os tecidos. Diante a inter-relação simultânea dessas doenças, surge a necessidade deum tratamento integrativo que promova reparação tecidual e redução microbiana. Para isso, a utilização dos lasers de baixa potência em associação com agentes fotossensibilizadores, chamada de terapia fotodinâmica (PDT), vem ganhando espaçona rotina clínica. O objetivo deste trabalho foi relatar um caso clínico da utilização de terapia fotodinâmica com azul de metileno no tratamento de lesão endoperio.Paciente normossistêmico, procurou consultório odontológico e após o exame clínico e radiográfico, foi observado no elemento 46 extensa lesão periapical, fístula, mobilidade grau 3 e profundidade de sondagem de 5 e 7 mm na mesial. Na fase de tratamento endodôntico,foi inserida medicação intracanal à base de hidróxido de cálcio por 30 dias. Em seguida, realizou-se 2 sessões de PDT intracanal e na bolsa periodontal com intervalo de 15 dias. Passado esse período, realizou-se aobturação dos condutos. Os tratamentos periodontal e endodôntico foram proservados. Após 3 meses,foi observada melhora nos parâmetros clínicos e radiográficos, com redução do grau de mobilidade e melhora nos níveis de inserção periodontal. Os resultados sugerem que o tratamento multidisciplinar associado a PDT foram fundamentais para favorecer o reparo do caso.
