Use of Cystoscopy to Visualize Morphological Alteration of the Liver in a Posthatchling Turtle (Cuora trifasciata) (Case Report)

AbstractA 55 g, 7 mo old Chinese three-striped box turtle (Cuora trifasciata) was presented with a 2 wk history of lethargy and anorexia. The owner attempted various antibiotic treatments without clinical improvement. A cystoscopic evaluation of the coelom was performed. The liver appeared dark red-to-brown presenting multifocal irregularly shaped white-to-tan and roughly round areas of discoloration on the capsular surface. An adult keeled box turtle (Pyxidea mouhotii), which died in the...

Evaluation of Environmental Cytotoxic Drug Contamination in a Clinical Setting (Original Study)

AbstractThe use of cytotoxic drugs to treat neoplastic conditions is increasing in veterinary practices. Many agents have the potential to be genotoxic and evidence of exposure to cytotoxic drugs has been found in healthcare workers handling these pharmaceuticals. To date, limited contamination evaluations have been performed in veterinary practices. Evaluation for carboplatin contamination was performed at a veterinary teaching hospital involving twelve areas in the dispensary and treatment...

Microscopic Evaluation of Urine Sediment: Are There Different Ways?

OVERVIEW Urine samples are labile; components of the urine sample may change or may be lost during the delay between sample collection and sample analysis. Ideally, urine samples should be examined soon after collection by a trained individual. Routine urinalysis is a test that may improved by performing it in-house. INTRODUCTION Complete urinalysis includes assessment of several physical and chemical characteristics of urine. It is a simple, economical test that requires...

Cytology in the Evaluation of Lymphoid Tissue in the Dog and Cat

LYMPH NODES Lymph node sampling and cytology is quick, easy, and usually rewarding. Cytologic samples of peripheral and/or internal lymph nodes may be collected by fine-needle aspiration biopsy or non-aspiration fine-needle biopsy techniques. Sampling can also be performed by imprints or scrapings from lymph nodes that have been surgically removed or at necropsy. Lymph node cytology is an excellent way to evaluate a lymphadenopathy whether it is a single, multiple, or a generalized...

Spinal Fluid Analysis: Methods for In-clinic Evaluation and Sample Preservation

OVERVIEW Cerebrospinal fluid (CSF) samples are labile. Ideally, CSF samples should be analyzed or preserved as soon as possible after collection. OBJECTIVES OF THE PRESENTATION This 15-minute presentation will present techniques for proper CSF sample handling, in-clinic evaluation, and preservation of samples for shipment to a referral laboratory. CSF SAMPLE LABILITY CSF contains very little protein; this causes the leukocytes that are present to deteriorate rapidly....

Synovial Fluid Evaluation: One Drop is All You Need

SUMMARY Synovial fluid analysis can be an important diagnostic test in cases of suspected polyarthropathy. The primary goal of synovial fluid analysis is to classify the fluid one of three ways: normal, non-inflammatory (mononuclear inflammation), or inflammatory (neutrophilic inflammation) joint fluid. If necessary, the critical parts of synovial fluid analysis can be performed on as little as one drop of fluid. Results of synovial fluid analysis seldom yield a specific, definitive...

Making the Most of Biopsy Materials: Sample Handling and Preparation

OBJECTIVES OF THE PRESENTATION This 15-minute presentation will present techniques for proper handling and submission of cytology (aspirates, fluids, etc.) and surgical biopsy samples. CYTOLOGY SAMPLES Aspiration of a Mass The size of the syringe and needle selected may vary with the consistency of the mass or tissue being aspirated: •  Lymph nodes and soft fluctuant masses: 22- to 25-gauge needles and 6- or 12-cc syringe. •  Hard, firm masses: 20- to...

Dry-mount Fecal Cytology

There are several diagnostic tests of feces that may be necessary during complete evaluation of patients with clinical signs referable to the gastrointestinal tract. Optimal fecal assessment, including potential tests (e.g., wet-mount fecal cytology, dry-mount fecal cytology, bacterial culture, fecal antigen detection methods, fecal flotation, fecal sedimentation, Baermann technique, etc.) and their required sample handling, diagnostic indications, and interpretations, have been compiled in a...

How To Avoid the Five Most Common Mistakes in Veterinary Dermatology

PITFALL #5: FAILURE TO OBTAIN A COMPLETE HISTORY In veterinary medicine, history often plays an essential role in helping us formulate a list of differential diagnoses. Obtaining a thorough history is CRITICAL in veterinary dermatology. The history truly is one of the most important parts of the dermatologic examination. You don't have time? Use dermatologic history forms. Several are available from various sources such as American Animal Hospital Association (AAHA), Veterinary...

Cytology of Inflammation

CYTOLOGIC PATTERNS OF INFLAMMATION Neutrophilic (Acute) Inflammation Preparations in which greater than 70% of the cells are neutrophils are referred to as neutrophilic inflamation. Suppurative or purulent Inflammation are other terms used when there is a marked predominance of neutrophils (greater than 85%). The most common cause is a bacterial infection but other organisms (e.g., sporotrichosis) and many noninfectious disorders (e.g., necrotic areas in tumors, immune-mediated disorders)...
