MORPHOLOGIC RBC ABNORMALITIES IN DOGS AND CATS – PART 2

We are continuing the last topic, where one important type of morphologic changes was missing. 😊 ERYTHROCYTE SHAPE Any variation in the shape of erythrocytes is called POIKILOCYTOSIS. When many different shapes are seen in the blood film, the general term is used. Otherwise we have more specific terms, and it is good to be...

MORPHOLOGIC RBC ABNORMALITIES IN DOGS AND CATS – PART 1

Microscopical assessment of erythrocyte morphology is an important clinical tool for diagnosing the cause of anemia and also some other disorders. Normal erythrocytes are circular discs with central pallor, which is much less prominent in cats than in dogs. Observing them under microscope, one should pay attention to their size, color, shape, structures in or...

ANEMIA – GENERAL DIAGNOSTIC APPROACH

ANEMIA is a decrease in the red blood cell mass that results in decreased oxygenation of tissues. On complete blood count (CBC), it can be diagnosed by red blood cell (RBC) count, hematocrit (HCT) or hemoglobin (Hb) below the reference values. Remember, in some situations, normal values of individual animal can be above (sight hounds)...

HEART SOUNDS

HEART SOUNDS

Heart sounds are created by blood flow and vibrations of tissues during the cardiac cycle and can be classified as transient (of short duration) and heart murmurs (abnormal, longer, occurring during normally silent part of the cycle). TRANSIENT HEART SOUNDS are: S1 – closure of AV valves at the beginning of the systole, S2 –...

CARDIOVASCULAR EXAMINATION

An older, coughing dog is brought into examination room. Owners claim, they noticed exercise intolerance, that was going on for a while, but attributed it to dog’s age. Our mind can quickly jump to the idea of heart disease and necessity for thoracic x-rays and echocardiography … We will probably really need them. But before...

PREPARATION OF BLOOD SMEAR

PREPARATION OF BLOOD SMEAR

Blood smear is a valuable diagnostic tool for differential count of white blood cells and evaluation of pathologic abnormalities in leukocytes (toxic neutrophils, left shift, blast cells), erythrocytes (polychromasia, anisocytosis, inclusions, irregular shape, parasites) and platelets (macroplatelets, platelet clumps). But to get the relevant information from it, the preparation of the smear requires a proper...

GENERAL APPROACH TO THE EMERGENCY PATIENT

Doesn’t matter whether you work in small private practice or large referral clinic, you probably can’t totally escape providing emergency veterinary care, which requires knowledge of all areas of medicine, fast thinking and immediate action. Emergencies happen all the time as complications during anaesthesia or even after routine procedures (as vaccinations) or when acutely injured...

SYNCOPE VS SEIZURES

Two conditions, both starting with »s«. But that is not their only similarity. Although their causes are different, they can look very similar and therefore can be confused. To differentiate between them is important for diagnosis and treatment, and a careful description of animal’s behaviour before, during and following the collapse can be very helpful....

GETTING STARTED WITH ABDOMINAL ULTRASOUND

Ultrasound is a very valuable diagnostic tool, almost an extension of a physical exam, that helps us with non-invasive visualisation of internal structures of the body. It uses very high frequency sound waves, that are generated by the probe and pulsed into the body where they interact with tissues. Returning signals – echoes – are...

NEUROLOGICAL EXAMINATION AS THE BASE FOR CLINICAL NEUROLOGY

Neurological cases can be challenging for the clinician. We must be aware, that before we decide for more advanced diagnostic procedures, the most important thing in evaluating dogs and cats with neurologic signs is gathering information on patient’s signalment and history and making a complete neurological examination. This is essential to establish an accurate anatomic...
