Pulmonary hypertension and right-sided heart failure in an adult llama with hepatic disease.

CASE DESCRIPTION: A 13-year-old llama was examined because of lethargy, inappetence, and syncope. CLINICAL FINDINGS: Physical examination revealed muffled heart and lung sounds and peripheral edema. Clinicopathologic abnormalities included lymphopenia, hyperglycemia, prerenal azotemia, mild hyponatremia, mild hypoalbuminemia, and high gamma-glutamyltransferase and creatine kinase activities. On ultrasonography, the liver appeared hyperechoic and ascites and pleural effusion were seen. Echocardiography revealed severe dilatation of the right atrium, right ventricle, and pulmonary artery; severe tricuspid regurgitation; and high right ventricular systolic pressure consistent with right-sided heart failure secondary to pulmonary hypertension. TREATMENT AND OUTCOME: Treatment with furosemide was attempted, but because of failing health, the llama was euthanized 4 weeks later. Macronodular cirrhosis of the liver, glomerulonephritis, and intimal fibrosis and medial hypertrophy of muscular pulmonary arteries were seen on histologic examination of postmortem specimens. CLINICAL RELEVANCE: Findings in this case were similar to those reported for human patients with portopulmonary hypertension secondary to hepatic cirrhosis. Pulmonary hypertension secondary to hepatic disease should be considered in the differential diagnosis of right-sided heart failure.

Intracranial abscess caused by Rhodococcus equi infection in a foal.

CASE DESCRIPTION: A 4-month-old Missouri Fox Trotter colt was examined for a 5-week history of head tilt after treatment for suspected pulmonary Rhodococcus equi infection. CLINICAL FINDINGS: Computed tomography revealed osteolysis of the occipital, temporal, and caudal portion of the parietal bones of the left side of the cranium. A soft tissue mass compressing the occipital region of the cerebral cortex and cerebellum was associated with the osteolytic bone. TREATMENT AND OUTCOME: A rostrotentorial-suboccipital craniectomy approach was performed to remove fragmented occipital bone, debulk the intracranial mass, and obtain tissue samples for histologic examination and bacterial culture. All neurologic deficits improved substantially within 3 days after surgery. Bacterial culture of the resected soft tissue and bone fragments yielded R equi. CLINICAL RELEVANCE: Intracranial surgery in veterinary medicine has been limited to dogs and cats; however, in select cases, extrapolation of surgical techniques used in humans and small animals can assist with intracranial procedures in horses.

Use of a rivet-like titanium clamp closure system to replace an external frontal bone flap after transfrontal craniotomy in a dog.

A 10-year-old spayed female dog was referred for surgical removal of a brain tumor that had been identified following an acute onset of seizure activity 2 weeks earlier. A computed tomographic evaluation involving contrast agent revealed the presence of a contrast-enhanced mass within the left olfactory lobe of the brain. After removal of the mass via a transfrontal craniotomy, the overlying frontal bone flap was replaced and secured by use of a biologically inert rivet-like titanium clamp closure system and 3 titanium alloy craniotomy line clamps. On reevaluation 4 weeks after tumor removal, the dog was free of seizure activity and had no proprioceptive deficits; according to the owner, the dog had marked improvement in its overall behavior and attitude. The titanium clamp closure system appears to offer an effective and rapid technique for the secure replacement of craniotomy bone flaps in dogs.

Phenotyping of transgenic cloned piglets.

Numerous reports list the abnormalities obtained from cloning sheep and cattle. To date, few reports provide detailed information regarding the overall health status and performance data of cloned animals. This report follows three litters totaling 10 transgenic cloned piglets from birth through puberty. Significant findings from physical examinations and response to treatments are included, as well as necropsy data from five of the piglets that died during the study. The birth weights, placental weights, and growth rates for this group of piglets were not different from that of control animals raised in the same environment. Hematology and serum chemistry data were collected at 2 days of age, and at 2, 4, 8, 12, 16, 20, and 24 weeks of age. Results indicated a mild anemia and hypoproteinemia in the cloned piglets from birth through 4 weeks of age, but both conditions were corrected by 8 weeks of age. Echocardiography was performed on seven of the piglets. No anatomical defects were detected, but three of the piglets had decreased cardiac output values. However, both animals are growing and show no evidence of clinical disease. The immune system was evaluated by quantification of serum IgM and IgG levels and by determining the population of B-cells, macrophages, helper T-cells (CD4), cytotoxic T-cell (CD8), and double positive T-cells (CD4/CD8). With the exception of one animal, no abnormalities were detected with the immune system of the examined piglets. During the course of this study, five of the 10 piglets were euthanized or died, indicating there is a high mortality rate among cloned piglets, but the remaining five cloned piglets are free from detectable defects.

Sublumbar abscess and diskospondylitis in a cat.

Diskospondylitis is uncommon in cats. We describe a cat with diskospondylitis of the L7-S1 intervertebral disk, and a concurrent sublumbar abscess. Radiographic, computed tomographic and ultrasonographic findings are presented. Aerobic and anaerobic cultures of blood and spinal fluid yielded no growth. Aerobic and anaerobic urine cultures resulted in growth of an Enterococcus sp. and Clostridium perfringens, respectively. The cat was successfully treated with enrofloxacin and amoxicillin/clavulanic acid. Clinical signs resolved completely, and based on follow-up ultrasonography there was no remaining evidence of the sublumbar abscess. Etiologic agents and outcome from other cats with diskospondylitis are reviewed.

Kartagener's syndrome in a Dachshund dog.

Kartagener's syndrome (KS) is a rare, congenital condition characterized by situs inversus, rhinosinusitis, and bronchiectasis. An underlying ciliary dysfunction (e.g., immotility or dyskinetic beating) produces most of the clinical signs seen in affected animals. This case report reviews the history, clinical signs, and diagnosis of KS in a male, long-haired dachshund. This is the first known report of KS, and thus primary ciliary dyskinesia, in this breed of dog.
