Management of medial luxation of the shoulder joint in toy-breed dogs using an antiluxation pin placed lateral to the supraspinatus muscle tendon: 20 limbs (2017-2022).

Objective: To describe the clinical and diagnostic findings, surgical procedures, and clinical course of dogs with medial shoulder luxation (MSL) treated with a novel method using an antiluxation pin.

Animals: 18 client-owned toy-breed dogs (20 treated limbs).

Clinical Presentation: Toy-breed dogs with MSL were treated with the antiluxation pin (2017 to 2022).

Thoracic Vertebral Canal Stenosis and Vertebral Instability in a Young Minuet Cat.

This report describes a unique case of thoracic vertebral canal stenosis and vertebral instability in a 1 yr old Minuet cat. The cat presented with a history of chronic progressive nonambulatory paraparesis. Myelography with neutral and stress positions revealed dynamic compression at T1-4.

Cervical intervertebral disc disease in 307 small-breed dogs (2000-2021): Breed-characteristic features and disc-associated vertebral instability.

Objective: To evaluate the breed-characteristic features of cervical intervertebral disc disease (C-IVDD) and associated vertebral instability in small-breed dogs and to present the concept of intervertebral disc degeneration and associated instability stage, method of diagnosis, treatment and outcomes.

Animals: In total, 307 client-owned dogs with C-IVDD treated with spinal cord decompression with or without vertebral stabilization (2000-2021).

Methods: Information on age, sex, affected sites, stabilized sites, diagnostic methods for vertebral instability and outcomes were retrieved.

Alarm pheromone does not modulate 22-kHz calls in male rats.

Rats are known to emit a series of ultrasonic vocalizations, termed 22-kHz calls, when exposed to distressing stimuli. Pharmacological studies have indicated that anxiety mediates 22-kHz calls in distressed rats. We previously found that exposure to the rat alarm pheromone increases anxiety in rats.
