Outcomes following combined median sternotomy and ventral midline laparotomy for bicavitary penetrating wooden foreign bodies.

Combined abdominal and thoracic pathology caused by extra-gastrointestinal migration of an ingested wooden foreign body (WFB) is an uncommon but serious injury. Presenting clinical signs are typically nonspecific and, in the absence of observed WFB ingestion, diagnosis is challenging. Treatment requires concurrent abdominal and thoracic surgical exploration to remove the WFB and address injuries caused by its migration. This case series describes perioperative characteristics and outcomes in 4 dogs following combined median sternotomy and ventral midline laparotomy (CMSVML) for bicavitary penetrating WFBs. Key clinical message: Treatment of bicavitary penetrating WFBs with CMSVML provided postoperative outcomes similar to those in previous reports; however, high-grade complications and prolonged hospitalization were commonly encountered.

Résultats après sternotomie médiane et laparotomie médiane ventrale combinées pour des corps étrangers en bois pénétrant bicavitaires. La pathologie combinée abdominale et thoracique causée par la migration extra-gastro-intestinale d'un corps étranger en bois (WFB) ingéré est une blessure rare mais grave. Les signes cliniques présentés sont généralement non spécifiques et, en l'absence d'ingestion observée de WFB, le diagnostic est difficile. Le traitement nécessite une exploration chirurgicale abdominale et thoracique simultanée pour retirer le WFB et traiter les blessures causées par sa migration. Cette série de cas décrit les caractéristiques peropératoires et les résultats chez 4 chiens après une sternotomie médiane et une laparotomie médiane ventrale combinées (CMSVML) pour des WFB pénétrantes bicavitaires.Message clinique clé:Le traitement des WFB pénétrants bicavitaires avec CMSVML a fourni des résultats postopératoires similaires à ceux des rapports précédents; cependant, des complications de haut grade et une hospitalisation prolongée ont été fréquemment rencontrées.(Traduit par Dr Serge Messier).

Sertoli cell tumor/mixed germ cell-stromal cell tumor as separate neoplasms in a bilaterally cryptorchid dog.

An 11-year-old miniature poodle dog was presented with bilateral flank alopecia, gynecomastia, severe thrombocytopenia, and preputial edema. Based on characteristic clinical and hematological findings of hyperestrogenism and the presence of a caudal abdominal mass, a Sertoli cell tumor (SCT) was diagnosed. After a platelet concentrate transfusion, the SCT was surgically removed in addition to an atrophied contralateral testicle containing a mixed germ cell-stromal cell tumor. Recovery was uneventful. This combination of different neoplasms in separate testicles has yet to be documented. Key clinical message: This case of a SCT/mixed germ cell-stromal cell tumor combination in a bilaterally abdominal cryptorchid dog highlights common clinical signs associated with hyperestrogenism and the management of estrogen-induced myelotoxicity causing severe thrombocytopenia.

Un caniche miniature âgé de 11 ans fut présenté avec alopécie bilatérale des flancs, gynécomastie, thrombocytopénie sévère et oedème préputial. Sur la base des trouvailles cliniques et hématologiques caractéristiques d'hyperoestrogénisme et la présence d'une masse abdominale caudale, une tumeur à cellules de Sertoli (SCT) fut diagnostiquée. À la suite d'une transfusion d'un concentré de plaquettes, la SCT fut retirée chirurgicalement en plus d'un testicule controlatéral atrophié contenant une tumeur mixte à cellules germinales-cellules stromales. La guérison s'est passée sans problème. Cette combinaison de néoplasmes différents dans des testicules séparés n'avait jamais été documentée.Message clinique clé :Ce cas de combinaison de SCT/tumeur mixte cellules germinales-cellules stromales chez un chien cryptorchide abdominal bilatéral met en lumière les signes cliniques fréquents associés avec l'hyperoestrogénisme et la gestion de myélotoxicité induite par les oestrogènes causant une thrombocytopénie sévère.(Traduit par Dr Serge Messier).

Age of neutering contributes to risk of cruciate ligament rupture in Labrador Retrievers.

OBJECTIVE: Cruciate ligament rupture (CR) in Labrador Retrievers is a complex polygenic disease with high heritability. The environmental contribution to CR risk remains poorly characterized. An accurate genetic risk test for CR in the Labrador Retriever has been developed. This enables evaluation of environmental risk with knowledge of genetic disease predisposition through study of dogs with phenotypic disease status that is discordant with their genetic risk. The objective of this study was to identify environmental factors that contribute to CR in Labrador Retrievers through evaluation of dogs with clinical phenotypes that are discordantly predicted with the use of genetic markers. METHODS: Dogs were prospectively recruited between January 2013 and December 2022. To study discordant subjects, case dogs with a posterior risk probability value < 0.75 and control dogs with a posterior risk probability of > 0.25, determined with the use of an average of 8 statistical models, were selected. The environmental factors investigated were neuter status, age of neuter, withers height measured at the dorsal-most ridge between the scapulae, weight, body mass index, and athletic activity. RESULTS: Ninety three dogs were discordant: 58 dogs were discordant CR cases, and 35 dogs were discordant CR controls. Neutering before 12 months of age was a significant risk factor for CR development. Sex, neuter status, or status as an athlete was not associated with CR risk. CONCLUSIONS: Neutering before 12 months of age influences risk of CR in Labrador Retrievers. CLINICAL RELEVANCE: This information can inform management decisions about Labrador Retrievers regarding age of neutering, body condition, and athletic activity. The primary factor influencing CR development in Labrador Retrievers is polygenic intrinsic genetic risk.
