Acanthamoeba Infection in a Hematopoietic Cell Transplant Recipient: Challenges in Diagnosis, Management, and Source Identification.

We report a case of Acanthamoeba infection in an HCT recipient with steroid-refractory GVHD. We highlight the multiple challenges that free-living ameba infections present to the clinician, the clinical laboratory, transplant infectious disease for review, hospital epidemiology if nosocomial transmission is considered, and public health officials, as exposure source identification can be a significant challenge. Transplant physicians should include Acanthamoeba infections in their differential diagnosis of a patient with skin, sinus, lung, and/or brain involvement.

Thoracic and abdominal diagnostic imaging findings in dogs diagnosed with immune-mediated polyarthritis: 71 cases (2011-2023).

Objectives: To describe thoracic and abdominal imaging findings in dogs with immune-mediated polyarthritis and to evaluate their impact on the decision to commence immunosuppressive therapy.

Materials And Methods: Retrospective case series describing imaging findings in dogs with immune-mediated polyarthritis across modalities, including thoracic radiographs, abdominal ultrasound, computed tomography, and where available, echocardiography. Additionally, two internal medicine clinicians reviewed the signalment, clinical signs, clinicopathological findings and diagnostic imaging results on two separate occasions, reaching a consensus for each dog on whether immunosuppression would be their treatment of choice or whether their recommendations would be altered by the results of diagnostic imaging.

Open versus robotic-assisted techniques for multivisceral pelvic resections of locally advanced or recurrent colorectal and anal cancers: short-term outcomes from a single centre.

Background: Pelvic exenterations are now established as a standard of care for locally advanced and recurrent rectal cancer. Traditionally, these radical and complex operations have been performed via an open approach, but with the increasing expertise in robotic-assisted surgery (RAS), there is scope to perform such cases robotically. This study compares outcomes from open and RAS pelvic exenterations.
