The article presents a case study of a 9-year-old male who suffers from diffuse cylindrical bronchiectasis caused by eosinophilic bronchopneumopathy in dogs. It notes that a miniature pinscher-cross was assessed for his chronic coughing. The thoracic radiographs of the patient reveal multiple rounded bullae-like structures which is consistent with diffuse, cylindrical bronchiectasis.

The article presents a study on the diagnosis and treatment of gastrointestinal diseases in dogs which depends largely on histologic examination of biopsy samples. The study aims to assess the diagnostic value of biopsy samples taken from duodenum and ileum in dogs with diffuse gatrointestinal disease. It concludes that the type and severity of inflammation may vary depending on the anatomic site sampled in dogs with diffuse bowel diarrhea.

The article discusses a study which aims to determine the prevalence of intestinal nematode parasitism in dogs and to detect signalment factors associated with increased risk of infection in the U.S. The intestinal parasites examined consist of Toxocara, Ancylostoma and Trichuris species calculated with the number of positive dogs. It finds the importance of the risk of intestinal nematode infection depending on signalment and geographic location to help prioritize differentials in dogs.

The article offers a recap on a study regarding canine chronic hepatitis determination and ascites validation. It discusses the guidelines published by the World Small Animal Veterinary Association (WSAVA) about standardization of clinical and histologic subtypes of liver disease in small animals including necrosis, fibrosis, and hepatocellular regeneration. Further, it offers a commentary regarding the incidence of primary chronic hepatitis among dogs.

Disseminated Chrysosporium spp. infection was diagnosed in a German shepherd dog based on a positive fungal culture and cytological findings of intralesional fungi associated with granulomatous splenitis and neutrophilic lymphadenitis. The clinical presentation that could mimic a multicentric lymphoma, including markedly enlarged lymph nodes and a very abnormal splenic appearance on ultrasound makes this case even more atypical. The patient showed rapid clinical improvement on oral posaconazole and remains clinically stable ten months after diagnosis.

A miniature pinscher-cross was evaluated for chronic coughing. Computed tomography and bronchoscopy revealed severe, diffuse, cylindrical bronchiectasis secondary to eosinophilic bronchopneumopathy. Computed tomography is the gold standard for diagnosis of bronchiectasis in humans, and should be further investigated in dogs as a means of characterizing severity and pattern of disease.

Persistent canine nasal disease is a common complaint in small animal practice; however, an etiologic diagnosis can be difficult to establish. The aim of this retrospective study was to determine the percentage of cases for which the etiology was determined in our hospital population. Medical records from 80 dogs met the criteria of inclusion in the study. Nonspecific rhinitis was identified in 23.7% of cases. Other diagnoses were neoplasia (15.0%), fungal infection (nasal aspergillosis) (8.7%), cleft palate (8.7%), periodontal disease (4.0%), parasites (1.3%), foreign body (1.3%), and primary bacterial disease (1.3%). A definitive diagnosis could not be established in 36.3% of cases. Dogs with neoplastic and mycotic diseases often presented with severe radiographic and rhinoscopic lesions. Despite a systematic approach, numerous cases went undiagnosed. The use of advanced imaging should increase our ability to obtain an etiologic diagnosis in canine nasal disease.
