Viral Testing

Direct Microscopic Examination Microscopic examination of fluid or tissue samples from patients suspected of having a viral infection is unlikely to contribute to the diagnosis. Because viruses are small and generally intracellular particles, neither light microscopy nor viral culture techniques are used in the practice setting. Some commercial and academic laboratories do offer electron microscopy… Read More »

Aerosolized Drug Delivery Devices

Aerosolized drug therapy has been the standard treatment approach in human medicine for patients with noninfectious respiratory disease for 20 years. Administration via inhalation improves drug safety and efficacy by reducing the total therapeutic dose, minimizing drug exposure to other body systems, and allowing direct delivery of the drug to the lower respiratory tract. In… Read More »

Bronchoalveolar Lavage

Today the use of fiberoptic bronchoscopy is a common and standard diagnostic procedure, which allows direct observation of the upper and lower conducting airways. During passage of the endoscope through the nasopharynx, trachea, and large bronchi, the quantity of mucous secretions can be assessed readily in addition to the degree of mucosal edema and bronchospasm.… Read More »

Thrombocytopenia

Pathophysiology of Thrombocytopenia Thrombocytopenia may result from a variety of inciting factors, but in general three major mechanisms are considered: (1) reduced platelet production, (2) abnormal platelet distribution (sequestration), or (3) increased consumption or decreased platelet survival. Thrombocytopenia causes altered hemostasis due to insufficient phospholipid substrate for coagulation proteins. The platelet plug localizes activated clotting… Read More »

Interpretation of Peritoneal Fluid Changes in Peripartum Mares

Abdominal discomfort in the peripartum mare poses a diagnostic dilemma for the equine clinician because of the difficulty in differentiating between normal uterine contractions and other sources of abdominal pain. When a periparturient mare displays abdominal discomfort she may be experiencing a reproductive problem including uterine torsion or rupture, vaginal tear involving the peritoneal cavity,… Read More »
