There have been few reports of emergency cases of proximal tracheal foreign bodies in dogs and cats. Here, we report a dog and a cat that underwent an emergency tracheotomy for a foreign body in the proximal trachea. Case 1 was a dog with respiratory arrest caused by a large stone in the proximal trachea.

Objective: To investigate the outcome of surgical creation of multiple drainage holes (MDHs) versus local corticosteroid injection (LCI) for treatment of aural hematomas (AHs) in dogs and identify risk factors for recurrence and development of new AHs.

Animals: 51 dogs with 71 AHs.

Procedures: Medical records were reviewed, and information on signalment, clinical findings, and outcome was recorded.

Surgery and platinum-based chemotherapy are highly efficacious for treating advanced ovarian cancers in humans, but their efficacy is less known in dogs. We evaluated the long-term treatment outcomes of seven dogs with malignant ovarian tumors with malignant abdominal effusion. Ovariohysterectomies (OVHs) were performed on all dogs; four had ovarian adenocarcinoma (AC) with gross dissemination in the peritoneum (two with pleural effusion), and three had a granulosa cell tumor (GCT) with no gross dissemination in the peritoneal cavity, although one showed pleural effusion.

We evaluated the postsurgical outcomes of cutaneous or subcutaneous mast cell tumors (MCTs, n=25) in 23 dogs, resected with lateral surgical margins proportional to the widest tumor diameter, including at least one facial plane. The tumor diameter range was 0.3-2.

Several factors are suggested to be involved in the development of nontraumatic inguinal hernias (NTIHs) in dogs, but case series studies focusing on the etiology and treatment outcomes are limited. The aim of this study was to retrospectively evaluate the clinical characteristics and treatment outcomes of NTIHs in dogs. Medical records of 42 dogs with surgically treated NTIHs were reviewed.

Article Synopsis
  • * Three CDV strains (FXNO, YSA-TC, and MD-77) were tested, revealing that only the FXNO strain caused syncytia (cell fusion) and showed antigens after multiple passaging.
  • * Analysis of the infected CCT cells showed signs of cell death (apoptosis), characterized by specific DNA changes, indicating the virus's impact on cellular structure.
