An atypical presentation of anticoagulant rodenticide toxicosis in a dog.

A 5-month-old intact female Australian shepherd dog was referred to our clinic for neurologic signs including ataxia, a head tilt, and altered mentation following consumption of an unidentified rodenticide several days prior to developing clinical signs. A provisional diagnosis of bromethalin toxicosis had been made, given the neurologic signs seen and the general increased use of bromethalin-containing rodenticide products. However, on physical examination, the dog was noted to have scleral hemorrhage and bleeding at the venipuncture sites, which was inconsistent with bromethalin toxicosis.

Management of Attention-Deficit Disorder and Attention-Deficit/Hyperactivity Disorder Drug Intoxication in Dogs and Cats: An Update.

Amphetamines and the nonamphetamine atomoxetine are commonly used in the treatment of attention-deficit disorder/attention-deficit/hyperactivity disorder in humans. Because these medications are often found in homes, dog and cat exposure to these medications is a common intoxication. Amphetamine intoxication can cause life-threatening central nervous system and cardiovascular stimulation, even when small amounts are ingested.

Clinical presentation and management of suspected ribavirin toxicosis in a dog.

A 5-month-old pit bull terrier was presented for evaluation of progressive lethargy, vomiting, diarrhea, and anorexia 45 hours after ingestion of 625 mg/kg body weight (BW) (9000 mg) of the antiviral medication, ribavirin. Abnormalities that were detected included dehydration, tachycardia, elevated liver enzymes, and prolonged prothrombin time. The dog was discharged after 5 days of aggressive supportive care consisting of intravenous fluids, antiemetics, gastroprotectants, hepatoprotectants, dextrose supplementation, and vitamin B/K1 supplementation.

Management of attention-deficit disorder and attention-deficit/hyperactivity disorder drug intoxication in dogs and cats.

Two types of drugs are generally used for treating attention-deficit/hyperactivity disorder or attention-deficit disorder in humans: amphetamines or similar stimulants and the nonamphetamine atomoxetine. We describe the toxicity and treatment of both amphetamines and similar medications and atomoxetine in dogs and cats. Amphetamine intoxication can cause life-threatening stimulatory signs.

The outcome of intra-articular distal radius fractures treated with fragment-specific fixation.

Purpose: To assess the clinical, radiographic, and functional outcome of treating intra-articular distal radius fractures with fragment-specific fixation.

Methods: A retrospective review of 81 patients with 85 intra-articular distal radius fractures who were treated with fragment-specific fixation was performed. Minimum time to follow-up evaluation was 1 year, with a mean time of 32 months.

Direct measurement of methane hydrate composition along the hydrate equilibrium boundary.

The composition of methane hydrate, namely n(w) for CH4.n(w)H2O, was directly measured along the hydrate equilibrium boundary under conditions of excess methane gas. Pressure and temperature conditions ranged from 1.

Thermodynamic calculations in the system CH4-H2O and methane hydrate phase equilibria.

Using the Gibbs function of reaction, equilibrium pressure, temperature conditions for the formation of methane clathrate hydrate have been calculated from the thermodynamic properties of phases in the system CH4-H2O. The thermodynamic model accurately reproduces the published phase-equilibria data to within +/-2 K of the observed equilibrium boundaries in the range 0.08-117 MPa and 190-307 K.

Grain size-sensitive creep in ice II.

Rheological experiments on fine-grained water ice II at low strain rates reveal a creep mechanism that dominates at conditions of low stress. Using cryogenic scanning electron microscopy, we observed that a change in stress exponent from 5 to 2.5 correlates strongly with a decrease in grain size from about 40 to 6 micrometers.
