Investigation of pulmonary deposition of a nebulized radiopharmaceutical agent in awake cats.
OBJECTIVE: To determine whether conscious, unsedated cats will inhale a nebulized material administered via a facemask and whether this material will reach the lower airways. ANIMALS: 20 healthy adult cats. PROCEDURE: Technetium Tc 99m-diaminetriaminopentaacetic acid (99mTc-DTPA) was nebulized into a spacer and administered to the cats via a closely fitting facemask. By use of a gamma camera, images were then immediately obtained to determine the distribution of 99mTc-DTPA within the lower airways. RESULTS: Images obtained by use of the gamma camera revealed that all 20 cats had inhaled 99mTc-DTPA from the facemask. In each cat, deposition of the radiopharmaceutical agent was evident throughout the lung fields. CONCLUSIONS AND CLINICAL RELEVANCE: Awake cats that were not used to the application of a facemask did inhale substances from such a device. Aerosolization of medications may be a feasible route of administration for cats with lower airway disease.

Phosphate enema toxicosis in a pygmy goat wether.
Phosphate enema toxicity was diagnosed in a 7-month-old, castrated male, pygmy goat. On presentation, clinical findings included mild depression, tachycardia, tachypnea, rumen stasis, muscle tremors, hypocalcemia, hypokalemia, hypochloremia, hyperphosphatemia, azotemia, and metabolic acidosis. Fluid diuresis and parenteral antimicrobial therapy resulted in recovery after 3 d of treatment.

Neurologic complications after melarsomine dihydrochloride treatment for Dirofilaria immitis in three dogs.
Melarsomine dihydrochloride is highly effective against both sexes of adult and L5 Dirofilaria immitis. Common adverse reactions include injection site irritation and reluctance to move. Neurologic complications associated with i.m. injection of melarsomine dihydrochloride for treatment of heartworm disease in 3 dogs are described. Different degrees of neurologic complications have been identified; the pathophysiologic features are unknown. It is speculated that the compound migrates out of the injection site via fascial planes and causes an ascending inflammation along nerve roots. The resulting extradural cord compression secondary to extensive inflammation and necrosis of epidural fat could induce a variety of neurologic deficits. Alternatively, inappropriate injection technique may result in direct contact of melarsomine with neural tissue. A heightened awareness of proper injection technique might prevent the development of most neurologic complications.

The use of a low-profile cystostomy tube to relieve urethral obstruction in a dog.
A 10-year-old, spayed female Dalmatian was diagnosed with granulomatous urethritis causing urethral obstruction. Due to the extensive involvement of the urethra, a urethrostomy was not possible. A commercially available, silicone, low-profile gastrostomy tube was placed as a prepubic cystostomy tube to achieve urinary diversion. This tube is easy to use, has a one-way valve, and lies flush with the skin margin, thereby decreasing the likelihood of inadvertent removal. This tube should be considered to achieve long-term urinary diversion when urethral involvement is extensive.

AAHA senior care guidelines for dogs and cats.
This paper provides a working framework for enhancing the well-being of senior pet dogs and cats. Approaches to screening the medical status of senior pets are described in detail, with particular emphasis on establishing baseline data in healthy animals, the testing of clinically ill animals, and assessing senior pets prior to anesthesia and surgery. The management of pain and distress and the application of hospice and palliative care are addressed. Advice on ways to approach euthanasia and dealing with end-of-life issues is also provided.

Dietary-related skeletal changes in a Shetland sheepdog puppy.
A commercially available, renal failure diet was used to manage suspected renal failure in a 10-week-old Shetland sheepdog puppy. Rickets subsequently developed, possibly from low phosphorous intake and an increased calcium to phosphorus ratio. Decreased dietary calcium in addition to decreased phosphorus may have played a role in decreasing bone mineral density. Lethargy, decreased long bone growth, angular limb deformity, and osteopenia occurred, but these signs resolved within 3 months with nutritional management.
