ABSTRACT

A 14-week-old male unilaterally cryptorchid Clumber spaniel was presented for acute lethargy. Physical examination revealed abdominal pain, and a single testis was palpated in the scrotum. Abdominal ultrasound and computed tomography (CT) revealed a poorly vascularized, ovoid structure immediately caudal to the left kidney with scant regional peritoneal effusion. Left intra-abdominal testicular torsion was confirmed at surgery, and routine cryptorchidectomy was performed. The patient recovered uneventfully from anesthesia and surgery. Key clinical message: The most common CT characteristics of testicular torsion were present in this case and correlated well with sonographic findings to allow for rapid, accurate diagnosis and surgical planning of unilateral, non-neoplastic, intra-abdominal cryptorchid testicular torsion in a juvenile dog. Contrast enhanced CT facilitated accurate localization of the undescended testis and evaluation of testicular perfusion and may be a useful alternative to ultrasound for diagnosing testicular torsion, especially in indeterminate cases.


Tomodensitométrie d'une torsion testiculaire chez un chien juvénile atteint de cryptorchidie unilatérale. Un épagneul Clumber avec une cryptorchidie unilatérale âgé de 14 semaines a été présenté pour une léthargie aiguë. L'examen physique a révélé des douleurs abdominales et un seul testicule a été palpé dans le scrotum. L'échographie abdominale et la tomodensitométrie ont révélé une structure ovoïde mal vascularisée immédiatement caudale au rein gauche avec peu d'épanchement péritonéal régional. Une torsion testiculaire intra-abdominale gauche a été confirmée lors de la chirurgie et une cryptorchidectomie de routine a été réalisée. Le patient s'est remis sans incident de l'anesthésie et de la chirurgie.Message clinique clé:Les caractéristiques tomodensitométriques les plus courantes de la torsion testiculaire étaient présentes dans ce cas et bien corrélées avec les résultats échographiques pour permettre un diagnostic rapide et précis et une planification chirurgicale de la torsion testiculaire avec cryptorchidie unilatérale, non néoplasique et intra-abdominale chez un chien juvénile. La tomodensitométrie avec contraste a facilité la localisation précise du testicule non descendu et l'évaluation de la perfusion testiculaire et peut être une alternative utile à l'échographie pour diagnostiquer la torsion testiculaire, en particulier dans les cas indéterminés.(Traduit par Dr Serge Messier).

ABSTRACT

Oxacillin-susceptible, mecA-positive Staphylococcus aureus isolates create a treatment challenge for the clinician. In this article, we describe two cases of bacteremia from isolates that carried the mecA gene but were susceptible to oxacillin (oxacillin-susceptible methicillin-resistant S. aureus [OS-MRSA]). DNA microarray analysis was used to characterize these isolates as a mecA-positive, clonal complex 5, pediatric strain and a mecA-positive, clonal complex 8, USA300 strain.

ABSTRACT

The introduction and subsequent widespread use of intravenous catheters have presented physicians a double-edged sword. Although safe and stable vascular access has become essential to modern medical practice, bloodstream infection involving these catheters (particularly central venous catheters [CVCs]) is a major cause of morbidity and mortality in the United States. In this comprehensive review, the author discusses the most common sources of catheter-related infections, current diagnostic and treatment methods, and graded evidence-based recommendations for prevention of these infections.
