Disseminated angiostrongylosis with massive cardiac and cerebral involvement in a dog from Italy

A case of disseminated angiostrongylosis caused by Angiostrongylus vasorum in a dog living in Italy is here described. The dog was referred for severe respiratory distress and epileptic seizures; clinicopathological findings were consistent with severe pneumonia associated with right-sided heart failure and multifocal involvement of the brain. Bronchoalveolar fluid analysis identified a multitude of nematode larvae, identified as A. vasorum by conventional and biomolecular (PCR) methods. The major anatomo-histopathological lesions were chronic granulomatous pneumonia, a severe multifocal granulomatous myocarditis and multifocal mild vascular and inflammatory disease in the brain. A. vasorum should be included among the differentials of dogs with cardiovascular and neurologic disease.

IMAGING DIAGNOSIS—TRANSESOPHAGEAL ULTRASOUND‐GUIDED REMOVAL OF A MIGRATING GRASS AWN FOREIGN BODY IN A DOG

A 3-year-old English Setter dog was presented for an acute onset of coughing. Tracheobronchoscopic examination allowed localization and removal of one grass awn foreign body. A second migrated grass awn was suspected to be present in the left caudal lung lobe. Transesophageal ultrasound revealed an area of pulmonary consolidation in the dorsomedial portion of left caudal lobe and a linear hyperechoic structure consistent with a grass awn foreign body within the area of consolidation. Transesophageal ultrasonography was also used to provide anatomical landmarks that facilitated successful thoracoscopic removal of the foreign body.

Naproxen in the horse: pharmacokinetics and side effects in the elderly.

It is well-known that old animals show physiologic and/or pathologic variation that could modify the pharmacokinetics of drugs and the related pharmacodynamic response. In order to define the most appropriate therapeutic protocol in old horses, pharmacokinetic profile and safety of naproxen were investigated in horses aged over 18 years after oral administration for 5 days at the dose of 10 mg/kg b.w./day. After the first administration, the maximum concentration (Cmax 44.21 ± 9.21 μg/mL) was reached at 2.5 ± 0.58 h post-treatment, the harmonic mean terminal half-life was 6.96 ± 1.73 h, AUC0-24h was 459.71 ± 69.95 h μg/mL, MRT was 7.44 ± 0.74 h and protein binding was 98.47 ± 2.72%. No drug accumulation occurred with repeated administrations. No clinical and laboratory changes were detected after administration of naproxen. Gastric endoscopies performed after the treatment did not show pathological changes of the gastric mucosa.

A case of primary papillary disseminated adenocarcinoma of canine lung

Primary lung tumors are rare in dogs, whereas pulmonary metastatic neoplastic involvement is common. We describe a case of a 12-year-old male, mixed-breed dog with a 3-month history of coughing and dyspnea. The investigating protocol, which also includes transcutaneous pulmonary biopsy, allowed a diagnosis of lung adenocarcinoma that necroscopic findings confirmed as a primary neoplasia. The tumor exhibited a nodular-disseminated growth, mimicking the metastatic involvement of the lung, instead of the single-mass appearance that has been observed by other authors. The present report indicates that, although the incidence of canine primary lung neoplasms is markedly low, this condition must be considered in the differential diagnosis of lung diseases that cause coughing and dyspnea in older dogs.

Changes in Blood Parameters in Healthy Horses and Horses With Upper and Lower Respiratory Tract Diseases Undergoing Treadmill Exercise Tests

ABSTRACT Exercise tests are useful tools to evaluate the fitness level of horses in training or with a history of poor performance. The aim of this study was to evaluate the differences in blood parameters in three groups of horses undergoing treadmill exercise tests, either to detect the cause of exercise intolerance or to evaluate the level of fitness before a competition. Blood samples were taken from 30 horses before, at the end of, and two hours after a standardized treadmill exercise test, to detect differences in hematological parameters between healthy horses (10, group N), horses with upper (10, group U), and lower airway diseases (10, group L). Packed cell volume, erythrocyte number, hemoglobin, glucose, and total and unconjugated bilirubin concentration were statistically different between the groups, because of increased oxygen demands in respiratory diseases and intravascular hemolysis. This could occur during exercise and is worsened by the increased breakdown of erythrocytes secondary to exercise‐induced pulmonary hemorrhage, diagnosed in horses in group L. HIGHLIGHTSStandardized exercise tests are useful in investigating poor performance in horses.Hematologic parameters were influenced by respiratory diseases.Bilirubin was higher in horses with lower airway diseases.

Chronic renal failure (CRF) in horses: personal reports.

Chronic renal failure (CRF) is rare in horses, mostly appearing in subjects over 15 years of age (Schott, 1998). However, CRF has been also described in horses less than 5 years of age as a congenital disorder (Aguilera-Tejero, 2000). Progressive weight loss is the most common clinical sign, associated with hypercalcaemia and hypophosphataemia. As these clinical and laboratory findings may also be related to other extrarenal diseases, CRF must always be considered, even though it is rare. This paper describes two cases of CRF in horses.
