Special Issue Information

Dear Colleagues,

This Special Issue will focus on the latest advancements in diagnostic, therapeutic, and management strategies across various branches of internal medicine in small animals. It will explore cutting-edge research, innovative clinical practices, and the integration of new technologies in veterinary medicine.

The scope encompasses both clinical and translational research related to small animal internal medicine. It invites contributions from diverse fields that have a direct impact on internal medicine. The Special Issue will include original research articles, review articles, case reports, and perspectives on future challenges and opportunities in the field.

The primary purpose is to provide a comprehensive resource for veterinarians, researchers, and students in understanding the latest developments in small animal internal medicine. By showcasing innovative approaches and research findings, the Special Issue aims to enhance patient outcomes and foster interdisciplinary collaboration within the veterinary community.

This Special Issue will serve as a valuable complement to existing literature by bridging the gap between cutting-edge research and practical clinical applications in small animal internal medicine. It emphasizes the integration of emerging technologies, such as AI-based clinical decisions, which are not yet extensively covered in traditional resources. Additionally, the Special Issue addresses unmet needs by focusing on underexplored areas, including rare diseases, breed-specific conditions, and tailored therapies.

Feline lower urinary tract disease (FLUTD) is a frequent diagnosis in cats, with bacterial causes constituting a minor percentage of cases. This observational study aimed to assess the diagnostic and therapeutic approaches to FLUTD among Italian veterinarians and explore variations in different workplaces. Data were collected via an anonymous survey completed by 317 veterinarians from small clinics (SC), large clinics (LC), and veterinary hospitals (VH). Results revealed that approximately half of respondents relied on clinical signs and urinalysis for diagnosis, while fewer incorporated abdominal ultrasound. Urine culture and sensitivity (UCS) testing was infrequently performed, primarily due to financial and logistical constraints, with higher compliance in VH practitioners. Antimicrobials were widely employed, with enhanced penicillins being the most prescribed class. The frequent empirical use of quinolones raises concern regarding gaps in antimicrobial stewardship. Despite some adherence to the ISCAID guidelines, discrepancies in diagnostic rigor, antimicrobial selection, and treatment duration were observed. Larger facilities demonstrated greater alignment with evidence-based practices, emphasizing the need for widespread education on appropriate antimicrobial use. This study underscores the importance of integrating guideline-based diagnostics and stewardship in managing feline urinary tract diseases. Full article

Dyspnea is common in feline emergency medicine. Dyspneic cats are often unable to tolerate additional diagnostic tests upon admission. The aim of this study was to determine the relative frequency of the causes of severe dyspnea in cats and to identify clinical indicators that could guide immediate management. Records of 312 severely dyspneic cats admitted over a 5-year period to our institution’s emergency and critical care unit were retrospectively reviewed. The cause of dyspnea was identified for 258 cats, representing 83% of the cases. This study focused solely on these 258 cats. Respiratory causes accounted for 33% of cases, followed by cardiac causes (25%) and both traumatic and neoplastic causes (21% each). Pleural effusion was present in 39% of the cats, with various origins: cardiac (38%), respiratory (pyothorax, feline infectious peritonitis, 30%), neoplastic (23%), and traumatic (9%). Male cats were significantly overrepresented in the cardiac and respiratory groups. The median age differed according to the cause (2 years for traumatic causes, 6 years for respiratory causes, and approximately 11 years for cardiac and neoplastic causes). Cats with cardiac disease were significantly more often hypothermic. Hyperthermia was not systematically indicative of an infectious process. No clinical element (temperature, heart rate, cardiac auscultation, etc.) allowed for predicting the cause of dyspnea. In-hospital mortality was 44%, varying according to the cause (78% for neoplastic causes, 40% for traumatic causes, 37% for cardiac causes, and 30% for respiratory causes). In conclusion, the four main categories of causes were represented in approximately equal proportions, which contrasts with the results of the British RAPID CAT study, where cardiac causes accounted for nearly two-thirds of dyspnea cases. In the dyspneic cats in this series, the clinical presentation did not allow clinicians to identify a particular cause. This highlights the importance of non-invasive examinations such as POCUS (point-of-care ultrasound), which has become a routine test in emergency medicine. However, this importance should not lead to underestimating the continued value of radiography when the cat’s clinical condition allows for image acquisition. Full article

The study of the function of the right ventricle (RV) is a topic of great interest in the scientific community, and some studies have evaluated parameters of the right ventricular systolic function and have correlated them to various RV pathologies and possible clinical findings. Less information was obtained on the right ventricular diastolic function. In veterinary medicine, the characteristics of the restrictive RV and the presence of end-diastolic forward flow (EDFF) in patients with pulmonary stenosis have not yet been described. This type of flow is an antegrade flow that is observed with the Doppler study of the pulmonary artery and occurs at the end of the diastolic phase. Pulmonary valve stenosis (PVS) is one of the most common congenital heart diseases in dogs. The echocardiographic parameter that is mainly taken as a reference for evaluating the severity of the disease is the peak gradient of the pulmonary antegrade flow. For our retrospective study, we consider a total of 164 dogs with PVS divided into 149 dogs with type A and 15 type B, seen at a reference veterinary clinic from 2020 to 2024. All these dogs underwent echocardiographic examinations to observe the morphological characteristics of the PVS and consider the presence or absence of restrictive RV with EDFF. An independent sample t-test analysis revealed that the severity of PVS is greater in dogs with EDFF, both in the group of patients with type A stenosis and in patients with type B stenosis. This study suggests that RV restrictive physiology is common in dogs with severe PVS. Full article
