Making Sense of Blood Gases
Confused by metabolic acidosis? Baffled by anion gaps? The Acid-Base handouts are a great review of blood gas analysis from sample collection to understanding compensation. Thanks to Teresa Reiser VMD, DACVECC for this practical overview of a tricky but valuable topic.
Have you seen the newest Medical FAQs!
The Dental Nomenclature FAQ shows you how to correctly name or number your patients' choppers. And while we're in the oral cavity, you can find out all you ever wanted to know about Oral Melanomas. Stumped by a ferret tumor? Read the Ferret Insulinoma FAQ! And of course, with the the festive season fast approaching, dogs and cats are getting into things they shouldn't. Here's some tips on how to handle some common Dangerous Foods. Check out the rest of the VIN Medical FAQs!

Retinoic acid as a novel medical therapy for Cushing's disease in dogs
Cushing's disease is almost always caused by an ACTH-secreting pituitary tumor, but effective medical therapy is currently limited. Because retinoic acid has been shown to be potentially useful in decreasing corticotroph secretion and proliferation in rodent models, we have studied its action in dogs with Cushing's disease. This study highlights the possibility of using retinoic acid as a novel therapy in the treatment of ACTH-secreting tumors in humans with Cushing's disease.
Feline progressive histiocytosis
Histiocytic proliferative diseases include reactive and neoplastic proliferations of dendritic cells (DC) or macrophages. Various forms of DC proliferations have been documented in humans and dogs; their etiology is largely unknown. With the exception of a few case reports, histiocytic proliferations have not been characterized in cats. This study summarizes clinical, morphologic, and immunophenotypic features of a feline progressive histiocytosis (FPH) in 30 cats.
Oxygen concentration is an important factor for modulating progesterone synthesis in bovine corpus luteum
Oxygen deficiency caused by a decrease in the blood supply is known to induce various responses of cells. Luteal blood flow has been shown to decrease during luteolysis. To determine whether a low-oxygen condition is associated with functional luteolysis, we examined the influence of reduced oxygen tension on the luteal progesterone (P4) generating system in cultured bovine midluteal cells. The overall results indicate that a low-oxygen condition decreases P4 synthesis and suggests that oxygen deficiency is an essential condition for the progression of luteolysis in cattle.
Ultrasonography of the equine larynx
Nasopharyngeal and laryngeal evaluation is important when examining horses with upper airway signs for poor performance. Currently endoscopy is the most common method to evaluate the equine upper airway. Ultrasonography of the equine larynx has not previously been described. Using six cadaveric specimens and four standing horses, the ultrasonographic appearance of the equine larynx was established. Ultrasound allowed visualization of portions of the hyoid apparatus, laryngeal cartilages, associated soft tissues, and intrinsic and extrinsic laryngeal musculature, that are not seen using endoscopy. Additionally, real-time ultrasound allowed observation of the movement of the vocal folds and the arytenoid cartilages during respiration.
Person Brought In Nearly Dead Stray Cat, Said She Wouldn't Pay For Care, And Then Was Shocked When I Recommended Euthanasia. What Would You Do?
At our clinic, if you are not the owner, you will get absolutely zero information about a patient. If a good Samaritan doesn't want financial responsibility, that means they are not the owner. IF (and that's a big if) I agree to take possession of a stray, the one who brought it in is told that we will do what is best for the cat. If they don't like that answer they can take it somewhere else. I'm here for the cat, not the complete stranger who walked through my door and will never be back again.
Puppy With Umbilical Hernia Near Xiphoid -- Radiographs Show Probable Peritoneal Pericardial Diaphragmatic Hernia
This chest appearance strongly suggests a peritoneal-pericadial diaphragmatic hernia. I outlined what I would call the limits of the cardiac border in the repost below. See what you think. You can confirm this rapidly with ultrasound but, you do not need an ultrasound study necessarily. You could do a positive contrast celiogram. Inject 1 cc/lb of positive contrast medium (iodinated) into the peritoneal cavity. Massage the abdomen for 15 -30 seconds, and make two views. You will see contrast medium travel into the pericardial sac. Make your injection caudal to the umbilicus (to avoid falciform fat) and slightly off midline to the right.
Pharmacists Writing Prescriptions, Alberta
Starting later this year, pharmacists will be able to more fully use their expertise by being able to write some prescriptions. This will provide better access to drug treatments, especially for basic prescriptions and refills.
How To Get People To Schedule Recommended Dental Procedures?
Anything over a grade 1 dental gets this from me in the exam room: "We need for you to schedule Harvey's oral procedure visit as soon as possible, before it worsens into a generalized infection. I want to deal with this sooner rather than later so I can prevent even more severe problems. When we're done here I'll walk out to the desk with you and check to see what my earliest available open date is." And I DO walk out to the discharge desk with owner, look at the schedule (or ask the discharge person to check it for me), and see that it gets booked. People are (impressed)(intimidated)(relieved)-- choose your descriptor -- that I have taken the trouble to do that. I think it emphasizes to them how important I feel it is.
