Case report: Androgen-secreting adrenocortical tumors in eight cats.

Urine marking, aggression, and other behavioral concerns are common reasons for cat owners to seek veterinary care. Empiric treatment for lower urinary tract disease or primary behavior disorders are commonly pursued, especially in those cases with normal routine laboratory evaluations. Herein, we report the clinicopathologic findings in eight sexually altered cats that were diagnosed with androgen-secreting adrenocortical tumors.

Pediatric mediastinal mass algorithm: A quality improvement initiative to reduce time from presentation to biopsy.

Background: Mediastinal masses in children may present with compression of the great vessels and airway. An interdisciplinary plan for rapid diagnosis, acute management, and treatment prevents devastating outcomes and optimizes care. Emergency pretreatment with steroids or radiation is more likely to be administered when care is variable, which may delay and complicate diagnosis and treatment.

Adipose-derived human stem/stromal cells: comparative organ specific mitochondrial bioenergy profiles.

Background: Adipose-derived stem/stromal cells (ASCs) isolated from the stromal vascular fraction are a source of mesenchymal stem cells that have been shown to be beneficial in many regenerative medicine applications. ASCs are an attractive source of stem cells in particular, due to their lack of immunogenicity. This study examines differences between mitochondrial bioenergetic profiles of ASCs isolated from adipose tissue of five peri-organ regions: pericardial, thymic, knee, shoulder, and abdomen.

Cervical dermoid sinus in a cat: case presentation and review of the literature.

A 6-month-old female spayed domestic shorthair cat was presented for evaluation of a focal subcutaneous swelling on the dorsal neck at the level of atlas. The magnetic resonance imaging and surgical treatment of a dermoid sinus associated with the cervical vertebrae is described. To the authors' knowledge, a dermoid sinus in this location has not been described previously in the cat.
