Special Issue Information

Dear Colleagues,

Respiratory diseases in dogs and cats are considered part of general internal medicine, or cardiology. Moreover, there are few veterinarians specializing in this field, with only a few specialized departments. Therefore, research on respiratory diseases in dogs and cats is sparse. For the definitive diagnosis of respiratory diseases, endoscopic examination and imaging tests, such as CT/MRI under general anesthesia, are often necessary. However, they are not always possible in all cases owing to the risk of general anesthesia and other facility issues. This is one of the reasons why there has been so little research on respiratory diseases. Although a few reports have been made in Europe and the United States, these results cannot necessarily be applicable to dogs and cats in Japan and other Asian countries because the popular breeds are different from those in Europe and the United States. Consequently, we call for research on respiratory diseases in dogs and cats, especially in non-European countries and the United States.

The respiratory consequences of brachycephalic airway obstructive syndrome (BAOS) are well known; however, brachycephalic dogs may also present with alimentary tract signs. The electronic medical records of 176 French bulldogs with BAOS were reviewed to classify the gastrointestinal endoscopic findings, and to evaluate the associations between clinicopathological data, endoscopic respiratory, and digestive findings. Dogs that did not undergo endoscopic examination of both airways and the upper digestive tract were excluded. The type and frequency of respiratory and digestive signs were assessed according to a previously described grading system, in addition to gastrointestinal histopathological findings. Video documentation was reviewed to assign a score to each gastrointestinal endoscopic finding (EGF) and to obtain a total EGF score. All dogs showed at least one EGF. The median total EGF score was 5 (range 1–9). A significant association between the score from digestive signs and the total EGF score was found. In addition, laryngeal granulomas were significantly associated with regurgitation. No associations were found between gastrointestinal histopathological findings and the scores from respiratory or digestive signs. Overall, gastrointestinal endoscopic findings and laryngeal granulomas are common among French bulldogs with BAOS. Therefore, a systematic endoscopic approach to alimentary signs is desirable to determine the most appropriate treatment. Full article

Human studies suggest point-of-care ultrasound (POCUS) is superior to radiographs for diagnosing rib fractures, but its efficacy in veterinary medicine remains unclear. This study aimed to compare the sensitivity and specificity of POCUS and digital radiographs for detecting rib fractures in canine cadavers, using necropsy as the reference standard. Nine canine cadavers were randomly assigned to either a fracture or control group, with fractures created surgically. Blinded evaluations were performed by an expert and novice sonographer, as well as a board-certified radiologist and a novice radiograph interpreter. Sensitivity and specificity for detecting rib fractures were 83% and 99.74% for ultrasound and 82% and 99.22% for radiographs, with no significant difference between modalities. However, the time required to identify rib fractures varied significantly, with ultrasound taking considerably longer than radiograph interpretation. The expert and novice sonographers required an average of 26 and 64 min, respectively, whereas the radiologist and novice radiograph interpreter took 3 and 10 min. These findings suggest that POCUS and radiographs provide comparable accuracy in detecting rib fractures in canine cadavers. Excluding the time required to obtain radiographs, ultrasound takes longer than radiograph interpretation to identify rib fractures. While POCUS remains a valuable diagnostic tool, its practicality in a clinical setting needs further investigation. Full article

Abstract
In this prospective blinded study, canine C-reactive protein (c-CRP), haptoglobin (HPT), and 25-hydroxyvitamin-D (25(OH)D) were investigated for their diagnostic value in 55 dogs with nasal cavity disease (ND). After comprehensive diagnostics including a culture-dependent microbiological examination (ME) of nasal swabs, 17 dogs were [...] Read more.
In this prospective blinded study, canine C-reactive protein (c-CRP), haptoglobin (HPT), and 25-hydroxyvitamin-D (25(OH)D) were investigated for their diagnostic value in 55 dogs with nasal cavity disease (ND). After comprehensive diagnostics including a culture-dependent microbiological examination (ME) of nasal swabs, 17 dogs were excluded due to additionally detected systemic diseases or steroid pre-treatment. Included were 25 dogs with malignant ND (13 carcinomas and 12 sarcomas) and 30 dogs with benign ND (7 benign tumors, 13 idiopathic rhinitis (IR), and 10 others), as well as 10 controls. In none of the 72 dogs with ND was primary bacterial rhinitis diagnosed. Although within the reference interval, compared to the controls, c-CRP was significantly higher in dogs with ND in general and in every subgroup except for benign tumors. Serum HPT concentrations were not different among groups. Compared to the controls, 25(OH)D concentrations were significantly lower (p = 0.041) in malignant ND and sarcomas (p = 0.025). Despite pre-treatment with antibiotics (40/54; 74.1%), in 23/51 (45%) dogs, the ME was positive. Cultivated bacteria did not differ significantly between nasal diseases. The serum markers were not significantly different regarding the positivity of ME. In conclusion, the investigated serum markers were not clinically useful for the reliable detection of canine ND, as was the ME. Because of the low number of dogs with IR and positive or negative ME, further studies regarding c-CRP are needed in a larger group of IR dogs without concomitant diseases to reliably evaluate its utility in IR dogs with suspected secondary bacterial nasal infection.
