Dr. Otoni received her Veterinary degree from Sao Paulo State University, Brazil, in 2004 where she also completed a Small Animal Medicine Residency. In 2007, after completing an evaluated clinical year at the University of Wisconsin, she became licensed to practice Veterinary Medicine in The United States. She completed a small animal rotating internship in medicine and surgery at Virginia-Maryland Regional College of Veterinary Medicine followed by a three-year residency in Small Animal Internal Medicine at Iowa State University College of Veterinary Medicine. During her residency, Dr. Otoni was awarded a competitive research grant and completed a prospective clinical study on Inflammatory Bowel Disease in dogs. Dr. Otoni has published 6 papers over the past 4 years and continues to be engaged in research and becoming up to date on various subjects of small animal internal medicine.

Dr. Otoni’s professional and research interests are broad, but include gastrointestinal diseases, as well as interventional radiology and interventional endoscopy. She is experienced in numerous minimally invasive procedures like percutaneous antegrade and endoscopic retrograde ureteral stent placement, urethral stent placement, tracheal stent placement, nasopharyngeal stent placement, percutaneous cystolithotomy (PCCL), urethral collagen implant for urinary incontinence, urethral hydraulic occluder placement for urinary incontinence, perineal approach rigid cystoscopy in male dogs, subcutaneous ureteral bypass (SUB) placement, rhinoscopy, gastrointestinal endoscopy, cystoscopy, bronchoscopy, ectopic ureter laser ablation, lithotripsy, laparoscopic liver biopsy, endoscopic cautery polypectomy, among others.

She is a member of the Veterinary Interventional Radiology and Interventional Endoscopy Society (VIRIES), Comparative Gastrointestinal Society (CGS) and American Society of Veterinary Nephrology and Urology (ASVNU).

Dr. Otoni is very compassionate and believes the needs of her patients come first. She lives with her husband and their 2 cats Layla and Lila.

Papers Authored
Serologic and Fecal Markers to Predict Response to Induction Therapy in Dogs With Idiopathic Inflammatory Bowel Disease
Abstract: Little information is available of markers that assess the disease course in dogs with idiopathic inflammatory bowel disease (IBD). Evaluate relationship between disease severity and serum and fecal biomarkers in dogs with idiopathic IBD before and after treatment.

Fecal S100A12 Concentration Predicts a Lack of Response to Treatment in Dogs Affected With Chronic Enteropathy
Abstract: S100A12 is a potential biomarker of gastrointestinal inflammation in dogs and fecal S100A12 concentrations are correlated with disease severity and outcome. The aim of the present study was to investigate whether there was any association between pre-treatment fecal S100A12 concentrations in dogs affected with chronic enteropathy (CE) and the response to treatment. |

Alteration of the Fecal Microbiota and Serum Metabolite Profiles in Dogs With Idiopathic Inflammatory Bowel Disease
Abstract: Idiopathic inflammatory bowel disease (IBD) is a common cause of chronic gastrointestinal (GI) disease in dogs. The combination of an underlying host genetic susceptibility, an intestinal dysbiosis, and dietary/environmental factors are suspected as main contributing factors in the pathogenesis of canine IBD. However, actual mechanisms of the host-microbe interactions remain elusive. The aim of this study was to compare the fecal microbiota and serum metabolite profiles between healthy dogs (n = 10) and dogs with IBD before and after 3 weeks of medical therapy (n = 12).

Mitral Valve Dysplasia Characterized by Isolated Cleft of the Anterior Leaflet Resulting in Fixed Left Ventricular Outflow Tract Obstruction
Abstract: A 7-month-old, sexually intact male English toy spaniel weighing 4 kg was referred for evaluation of a subclinical cardiac murmur. Echocardiography disclosed fixed left ventricular outflow tract obstruction that was caused by attachment of a cleft anterior mitral valve leaflet to the interventricular septum. Neither atrial nor ventricular septal defects were detected. Fixed obstruction of the left ventricular outflow tract by a malformed mitral valve is rare in human beings and has not been previously reported in the dog.

Internal Medicine

What Is A Veterinary Internal Medicine Specialist?

A board certified veterinary internal medicine specialist is a licensed veterinarian who has obtained intensive, additional training in understanding how your pet's internal body systems function and in diagnosing and treating the many serious diseases that can affect the health of those systems. An internal medicine specialist has advanced training in the following disciplines:

  • Endocrinology
  • Cardiology
  • Gastroenterology
  • Hematology (study of the blood)
  • Immunology
  • Infectious Diseases
  • Nephrology/Urology
  • Neurology
  • Respiratory Diseases
  • Oncology

While your general practitioner veterinarian can diagnose and treat many health problems, certain diseases and conditions require the care of a doctor who has had specialized, intensive training in internal medicine in order to provide the very best outcome for your pet.

*Within the discipline of veterinary internal medicine, there are also veterinarians who specialize further in Small Animal Medicine, Cardiology, Neurology, and Oncology.

Why Does My Pet Need A Veterinary Internal Medicine Specialist?

Just as your own primary care physician may feel the need to refer you to the care of a specialist from time to time, your general practitioner veterinarian may feel your pet needs a specialist to help diagnose or treat a particularly complicated medical problem. While your general practitioner veterinarian can handle many aspects of your pet's care, just as in human medicine, there is sometimes a need for the attention of a specialist. You can be assured that a veterinarian who knows when to refer you and your pet for more specialized diagnostic work or treatment is one that is caring and committed to ensuring that your pet receives the highest standard of medical care for his or her problem.

While in some cases, your veterinarian may be able to simply consult with a specialist about your pet's care, in other cases it is necessary to actually refer you and your pet to the specialist for more advanced diagnostics and treatment. Board certified veterinary internists may also have access to specialized diagnostic or treatment tools that a general practitioner veterinarian may not have.

What Health Problems Does A Veterinary Internal Medicine Specialist Treat?

Board certified internal medicine specialists are trained to treat the most serious diseases and health problems that affect pets. They are also especially prepared to care for pets that may be facing multiple health problems. Thanks to better health care, more and more pets are living longer lives. As a result, an increasing number of older pets, just like older people, are coping with multiple disease states that can be very difficult to manage. For example, a cat with diabetes may also be suffering from kidney failure, or a dog in heart failure may also be diagnosed with cancer. Internal medicine specialists are uniquely prepared to oversee the care of these complicated cases. In other situations, a younger animal may develop a problem that used to be considered untreatable but is now manageable and perhaps even curable.

Here are some common diseases that frequently lead general practitioner veterinarians and concerned pet owners to seek the expertise of a specialist:

  • Cancer
  • Heart Disease
  • Gastrointestinal Diseases
  • Diabetes Mellitus
  • Immune Related Disorders
  • Kidney Dysfunction

Why Can't I See an Internal Medicine Specialist All the Time?

In some cases you can. In many practices, the 'general practitioner' veterinarian at a practice is also a boarded internal medicine specialist. General practice veterinarians, however, are also highly educated medical professionals who must meet ongoing continuing education requirements throughout their professional careers in order to maintain their licensure. When a specialist is needed, he or she is only a phone call or a visit away.

Will My Regular Veterinarian Still Be Involved?

In many cases, your regular veterinarian will still supervise your pet's veterinary care, especially if your pet is coping with multiple disease states or conditions. In other cases, your referral doctor will take over the majority of your pet's medical care. It depends on your pet's particular disease and health problem.

There are approximately 1400 board certified veterinary internal medicine specialists in the United States, and the number is growing.
