Endoscopy-assisted dacryocystorhinostomy in a dog.

Objective: To describe the use of an endoscope to assist in performing minimally invasive dacryocystorhinostomy in a dog to successfully manage a nasolacrimal duct cyst (dacryocyst).

Animal Studied: A 4-year-old female spayed American Staffordshire Terrier with chronic epiphora and swelling ventromedial to the nasal canthus of the right eye and reverse sneezing.

Procedures: Computed tomography revealed a fluid-filled cystic lesion of the right nasolacrimal duct with extensive nasal extension and secondary obstructive frontal sinusitis.

Caudoventral hip luxation in 160 dogs (2003-2023): A multicenter retrospective case series.

Objective: To describe patient characteristics, etiology, treatment outcomes and complications of caudoventral hip luxation (CvHL) in a large cohort of dogs and investigate factors associated with nonsurgical treatment outcomes.

Study Design: Multicenter retrospective case series.

Animal Population: A total of 160 client-owned dogs (170 limbs).

Cortical thickness adaptation to combined mechanical loading and parathyroid hormone treatments is site specific and synergistic in the mouse tibia model.

In this study, we aimed to quantify the localised effects of mechanical loading (ML), low (20 μg/kg/day), moderate (40 μg/kg/day) or high (80 μg/kg/day) dosages of parathyroid hormone (PTH), and combined (PTHML) treatments on cortical bone adaptation in healthy 19-week old female C57BL/6 mice. To this end, we utilise a previously reported image analysis algorithm on μCT data of the mouse tibia published by Sugiyama et al. (2008) to measure changes in cortical area, marrow cavity area and local cortical thickness measures (ΔCt.

Cortical bone adaptation response is region specific, but not peak load dependent: insights from CT image analysis and mechanostat simulations of the mouse tibia loading model.

The two major aims of the present study were: (i) quantify localised cortical bone adaptation at the surface level using contralateral endpoint imaging data and image analysis techniques, and (ii) investigate whether cortical bone adaptation responses are universal or region specific and dependent on the respective peak load. For this purpose, we re-analyse previously published CT data of the mouse tibia loading model that investigated bone adaptation in response to sciatic neurectomy and various peak load magnitudes (F = 0, 2, 4, 6, 8, 10, 12 N). A beam theory-based approach was developed to simulate cortical bone adaptation in different sections of the tibia, using longitudinal strains as the adaptive stimuli.

Cystoscopic-guided scissor transection of intramural ectopic ureters as a novel alternate minimally invasive treatment option to laser ablation in female dogs: 8 cases (2011-2020).

Objective: To evaluate the safety and efficacy of cystoscopic-guided scissor transection of ectopic ureters (CST-EU) in female dogs.

Animals: 8 incontinent female dogs with intramural ectopic ureters.

Procedures: For this retrospective case series, data were collected from medical records of dogs that underwent CST-EU to relocate the ectopic ureteral orifice to an anatomically normal trigonal location between June 2011 and December 2020.
