Neoplastic diseases are common in African pygmy hedgehogs (), with squamous cell carcinoma (SCC) being the most prevalent oral tumor. Traditional imaging techniques like computed tomography (CT) have limitations in accurately defining tumor extent and detecting metastasis. In this study, a hedgehog with a suspected oral tumor underwent 18F-FDG PET/CT imaging, revealing a hypermetabolic lesion consistent with SCC and indications of metastatic activity.

Two spayed female mongrels were presented for an abdominal mass and metastasis examination. To investigate suspected ovarian tumours and metastasis, F-2-deoxy-2-fluoro-D-glucose (F-FDG) positron emission tomography (PET)/computed tomography (CT) was performed. F-FDG PET revealed mildly increased glucose uptake (maximum standardised uptake values, 2.

Article Synopsis
  • ACE inhibitors (ACEi) can worsen kidney function in dogs, so it's important to recheck renal function within 1-2 weeks after starting treatment.
  • A study analyzed 156 dogs on ACEi to identify risk factors for worsening renal function (WRF), finding that 17% experienced WRF, which was mostly mild to moderate.
  • The main risk factors for WRF were concurrent use of furosemide and pre-existing kidney issues (azotemia), highlighting the need for cautious use of ACEi in these cases.

Introduction: Small-field-of-view (SFOV) gamma cameras can offer higher sensitivities than conventional gamma cameras. However, there are currently no reports on the efficacy and safety of thyroid scintigraphy using SFOV gamma cameras in veterinary medicine. Therefore, we aimed to evaluate the efficacy and radiation safety of an SFOV gamma camera for feline thyroid scintigraphy.

A 13-year-old Maltese dog with an abdominal mass underwent 18F-FDG PET/computed tomography (CT) for tumor localization and metastatic evaluation. PET/CT scans revealed a gastric mass near the esophagogastric junction and demonstrated mean and maximum standardized uptake values (SUVs) of 4.596 and 6.

A 9-year-old, neutered male, domestic short-haired cat was referred for recurrent ascites of unknown etiology over a week. Physical examination revealed abdominal distension and ultrasonography revealed a large volume of ascites throughout the abdominal cavity; this was interpreted as modified transudate. The mesentery and abdominal fat were hyperechoic and edematous.

A 6-year-old spayed female domestic short-hair cat was presented for primary complaints of anorexia and lethargy. The cat was being treated with cyclosporine (25 mg/cat, PO q24h) and prednisolone (1 mg/kg, PO q12h) for feline hypersensitivity dermatitis and inflammatory bowel disease for 1 year, wherein prednisolone was withdrawn 2 weeks prior to presentation. At presentation, dehydration, hyperglycaemia, ketonaemia, increased fructosamine, glucosuria, ketonuria and metabolic acidosis were observed.

Changes in neutrophil-to-lymphocite ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have been identified in dogs with hypercortisolism (HC), but, no studies have investigated the changes in these inflammatory biomarkers as cost-effective and available parameters for the diagnosis and management of HC. This study was performed to evaluate whether NLR and PLR could be used as biomarkers for the diagnosis and treatment response in dogs with HC. This retrospective study included 67 dogs with HC, 58 dogs with non-adrenal illness (NAI), and 39 healthy dogs.

Objective: To evaluate the relationships between the severity of myxomatous mitral valve disease (MMVD) and pulmonary hypertension (PH) and serum angiopoietin (Ang)-1 and Ang-2 concentrations in dogs with MMVD.

Animals: 74 dogs (control, n = 12; MMVD, n = 62) were included.

Methods: Serum Ang-1 and Ang-2 concentrations were estimated using the canine-specific ELISA kit.

Sphingosine-1-phosphate (S1P) is a signaling lipid mediator that is involved in multiple biological processes. The S1P/S1P receptor (S1PR) signaling pathway has an important role in the central nervous system. It contributes to physiologic cellular homeostasis and is also associated with neuroinflammation.

Multiple endocrine disorders are uncommon in veterinary medicine, and the disease combination is usually related to hypercortisolism or autoimmunity. Central-pituitary hypothyroidism, also refer to secondary hypothyroidism, can be caused by hypercortisolemic conditions and is well-recognized in human medicine. However, central hypothyroidism, including pituitary hypothyroidism, concurrent with hyperadrenocorticism, is rarely reported in veterinary medicine.

Vitamin D plays a role in anti-inflammatory processes, and the alteration of its metabolism is associated with the inflammatory processes of pancreatitis. This study was performed to evaluate the expression of the vitamin D receptor (VDR) and the two major enzymes that regulate vitamin D metabolism, 1α-hydroxylase (CYP27B1) and 24-hydroxylase (CYP24A1), in the canine pancreas and to compare their degrees of immunoreactivity between normal and inflamed pancreases. Five normal and inflamed pancreatic tissues each were obtained from six dogs.

It has been reported that hypertriglyceridemia can partially mediate between diabetes mellitus (DM) and pancreatitis in dogs, implying that another mediator, such as chronic hyperglycemia, might exist. Therefore, this study aimed to evaluate the relationship between hyperglycemia and serum canine pancreatic lipase immunoreactivity (cPLI) concentration in diabetic dogs. This retrospective cohort study included 26 client-owned diabetic dogs, divided according to their serum fructosamine levels (<500 μmol/L = well-controlled DM group; ≥500 μmol/L = untreated or poorly controlled DM group).
