Abstract

The increase in the canine geriatric population means that veterinarians are more often confronted with diseases that are more prevalent in patients in this age group. As in other organ systems, degenerative, neoplastic, and vascular diseases are the most prevalent neurologic disorders in older dogs. A neurological disease in an older dog poses a challenge for the clinician due to the presence of concomitant diseases and age-related changes that make it difficult to interpret the neurological examination. In addition, given the age of the patients, some owners do not allow advanced imaging tests, and it is necessary to establish the most likely presumptive diagnosis to initiate treatment. Although many of these diseases can cause clinical signs that can be very upsetting, some of them can be managed with symptomatic therapy and have a good prognosis, such as idiopathic vestibular syndrome. Moreover, advances in and the greater availability of therapeutic options such as surgery and radiation therapy may increase survival and quality of life in diseases with a more serious prognosis, such as tumours. The aim of this review is to summarize the clinical presentation, diagnosis, and treatment of the more frequent diseases affecting the central nervous systems of geriatric dogs.

Endoparasites of rabbits and hares.
Accurate gross and microscopic identification of endoparasites in rabbits and hares is an important element of the diagnostic work of veterinary anatomic pathologists. Given the zoonotic nature of rabbit and hare endoparasites, such as C. hepatica, E. cuniculi, and others, veterinary pathologists are ideally poised to make valuable contributions to the understanding of the disease ecology of these pathogens in the context of a One Health research program.

Emergency Approach to Acute Seizures in Dogs and Cats.
This review presents a systematic approach to the diagnosis and treatment of single seizures, cluster seizures, and status epilepticus in dogs and cats.

Duration of efficacy and effect of implant location in adult queens treated with a 9.4 mg deslorelin subcutaneous implant.
The average duration of action of the 9.4 mg deslorelin implant was 790 ± 155 days (range 525-1140 days) with no significant difference in duration or efficacy depending on implantation sites. The 9.4 mg deslorelin implant causes pharmacological sterilization for about 2 years in female cats, is fully reversible, and caused no clinically relevant side effects when administered at both interscapular and periumbilical sites.

Association between highly pathogenic avian influenza outbreaks and weather conditions in Japan.
We found that higher average air temperatures two to three weeks prior, lower average wind speeds four weeks prior, and longer sunlight hours two and four weeks prior to outbreaks were significantly associated with increased risk of HPAI outbreaks in Japan. These results suggest that weather may influence environmental survival and transmission of the virus, as well as patterns of wild bird movement that could seed new outbreaks.

The relationship between radiographic disc calcification score and FGF4L2 genotype in dachshunds.
Most dachshunds with 1 FGF4L2 copy have radiographic disc calcification scores that are associated with substantially lower risk of symptomatic disc disease. Radiographic disc calcification scores are similar in dachshunds with 0 and 1 FGF4L2 copies. Given the high allele frequency of FGF4L2, breeding to produce progeny with 1 FGF4L2 copy is expected to be a more achievable short-term goal for dachshund spinal health breeding programs than breeding for 0 copies. It is recommended that both K-n and FGF4L2 genotype status be considered when choosing dachshund breeding stock.
