History

A 5-month-old male leopard (Panthera pardus) was evaluated for lameness of the left hind limb of 2 weeks' duration. A hairline fracture of the left radius was diagnosed by the referring veterinarian. The leopard had been treated with aspirin and cage rest; however, the lameness had not improved. The leopard was being fed an all-meat diet.

On physical examination, the leopard was unable to stand and palpation of the left hind limb elicited signs of pain. A high phosphorus concentration (9.4 mg/dL; reference range, 5.1 to 8.3 mg/dL) was the only abnormality detected on serum biochemical analyses;

History and Physical Examination Findings

An 11-year-old 40-kg (88-lb) spayed female Labrador Retriever was referred to a veterinary dental specialty practice for evaluation of a suspected cyst affecting the caudal aspect of the left mandible. Two months earlier, the dog's owner had noticed a large swelling at that location. The primary care veterinarian had obtained radiographs of the affected area and collected multiple bone and soft tissue biopsy samples. Histopathologic findings included the presence of fibrosis and reactive bone as well as a squamous epithelial lining. The described swelling was diagnosed as an odontogenic cyst. Within a few weeks, the

Abstract

Objective—To evaluate the use of technetium Tc 99m–labeled EDTA-biotin monomer (99mTc-EB1) as a scintigraphic imaging agent for soft tissue inflammatory lesions in horses.

Animals—6 healthy adult horses.

Procedures—First (phase 1), the agent's safety and blood-tissue clearance and an appropriate imaging protocol were determined in 6 horses. Each horse was injected with 99mTc-EB1 (1.1 GBq, IV, once); images were acquired at intervals during the following 24-hour period. Subsequently (phase 2), inflammation was induced via injection of 200 mg (10 mL) of mepivacaine (0.4 mg/kg) into the right neck musculature and perineurally in the proximal palmar metacarpal region of the right forelimb of 2 horses. Six hours after mepivacaine injection, 99mTc-EB1 (2.2 GBq, IV, once) was administered; 8 hours after injection, comparative soft tissue images were acquired after administration of technetium 99mTc-hydroxymethylene diphosphonate (99mTc-HDP; 7.4 GBq, IV, once).

Results—After injections of 99mTc-EB1, physical examinations, CBCs, and serum biochemical analyses revealed no abnormalities in any horse. Blood clearance of 99mTc-EB1 was rapid (A phase, 2.2 minutes; β phase, 58 minutes). Soft tissue uptake of 99mTc-EB1 was immediate and persisted for as long as 4 hours after injection. At 6 hours after IM and perineural mepivacaine injections, mepivacaine-induced inflammation was detectable by use of 99mTc-EB1.

Conclusions and Clinical Relevance—Results indicated that 99mTc-EB1 is safe for use in horses and can identify soft tissue inflammation without concurrent uptake in bone. Compared with 99mTc-HDP administration, use of 99mTc-EB1 extended the duration of soft tissue scintigraphic image acquisition.

Abstract

Objective—To evaluate the prevalence, distribution, and progression of radiographic abnormalities in the lungs of cold-stunned Kemp's ridley sea turtles (Lepidochelys kempii) and associations between these abnormalities and body weight, carapace length, and hematologic and plasma biochemical variables.

Design—Retrospective case series.

Animals—89 cold-stunned juvenile Kemp's ridley sea turtles.

Procedures—Medical records were reviewed. Dorsoventral and horizontal beam craniocaudal radiographs were evaluated for the presence, distribution, and progression of lung abnormalities. Turtles were categorized as having radiographically normal or abnormal lungs; those with abnormalities detected were further categorized according to the distribution of abnormalities (left lung, right lung, or both affected). Body weight, carapace length, and hematologic and plasma biochemical data were compared among categories.

Results—48 of 89 (54%) turtles had radiographic abnormalities of the lungs. Unilateral abnormalities of the right or left lung were detected in 14 (16%) and 2 (2%), respectively; both lungs were affected in 32 (36%). Prevalence of unilateral abnormalities was significantly greater for the right lung than for the left lung. Evaluation of follow-up radiographs indicated clinical improvement over time for most (18/31 [58%]) turtles. Prevalence of bilateral radiographic abnormalities was positively correlated with body weight and carapace length. There was no significant association between radiographic category and hematologic or plasma biochemical variables.

Conclusions and Clinical Relevance—Radiographic abnormalities of the lungs were commonly detected in cold-stunned Kemp's ridley turtles. Results of this study may aid clinicians in developing effective diagnostic and treatment plans for these patients.

Abstract

OBJECTIVE

To characterize osteolytic lesions in cold-stunned Kemp's ridley sea turtles (Lepidochelys kempii) hospitalized for rehabilitation and describe methods used for the management of such lesions.

ANIMALS

25 stranded, cold-stunned Kemp's ridley sea turtles hospitalized between 2008 and 2018.

PROCEDURES

Medical records of sea turtles with a diagnosis of osteolytic lesions were reviewed retrospectively to obtain the date of diagnosis, clinical signs, radiographic findings, microbial culture results, hematologic and plasma biochemical data, cytologic and histologic findings, antimicrobial history, time to first negative culture result, treatment duration, and outcome.

RESULTS

Lesions were identified radiographically a median of 50 days after admission and were located within epiphyses or metaphyses of various appendicular joints. Lesions were associated with periarticular swelling (n = 24), lameness (16), lethargy (2), and hyporexia (2). Bacterial culture yielded growth of single organisms (n = 16), multiple organisms (2), or no growth (6). Significant differences in hematologic and biochemical data were detected between the times of diagnosis and convalescence. Cytologic and histologic findings characterized the lesions as osteomyelitis leading to septic arthritis. Sixteen sea turtles were managed medically, and 8 were managed medically and surgically. Surgery resulted in rapid improvement in joint mobility and overall clinical status. Most (22/25 [88%]) sea turtles survived and were released after long-term management.

CONCLUSIONS AND CLINICAL RELEVANCE

During rehabilitation, cold-stunned Kemp's ridley sea turtles may be affected by osteomyelitis. Medical management based on antimicrobial susceptibility testing was effective for most turtles. Long term management efforts in turtles are justified by high survival rate.
