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 9 papers over the past 10 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, and 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.

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. |

Development and Validation of an Endoscopic Activity Score for Canine Inflammatory Bowel Disease
Abstract: The aim of this study was to develop and prospectively validate a simple endoscopic score of disease activity for dogs with inflammatory bowel disease (IBD).

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).

Systemic Levels of the Anti-Inflammatory Decoy Receptor Soluble RAGE (Receptor for Advanced Glycation End Products) Are Decreased in Dogs With Inflammatory Bowel Disease
Abstract: Inflammatory bowel disease (IBD) is a common condition in dogs, and a dysregulated innate immunity is believed to play a major role in its pathogenesis.

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.

Abstract: To evaluate the effects of the pacemaker funny current (I(f)) inhibitor ivabradine on heart rate (HR), left ventricular (LV) systolic and diastolic function, and left atrial performance in healthy cats and cats with hypertrophic cardiomyopathy (HCM).

Interventional Radiology

Interventional radiology (also known as IR) is the minimally invasive, image-guided treatment of medical conditions that once required open surgery. This is one of the fastest-growing fields in human medicine, and IR procedures are now routinely performed for a wide variety of conditions.

The main advantage of this minimally invasive approach to treating diseases is the shorter hospital stays, decreased pain, and a more rapid return to function.

An increasing number of the techniques used in human patients have been adapted for dogs and cats that have previously had limited or no therapeutic options.

VCA Arboretum View Animal Hospital is 1 of 7 hospitals in the USA to have an integrated operating room (Storz OR1), which allows multiple imaging modalities (endoscopy, CT, fluoroscopy, ultrasound) to be displayed on multiple monitors simultaneously.

IR uses fluoroscopic image-guidance to perform minimally invasive procedures. These images are like roadmaps that permit the clinician to guide instruments such as catheters and guide wires through the body gain access to different body part for diagnostic and therapeutic reasons.

Interventional Endoscopy (IE) utilizes advanced endoscopic techniques with other contemporary imaging modalities, such as fluoroscopy and/or ultrasound, which provides alternatives for patients in which conventional therapies are not indicated, or associated with excessive morbidity or mortality.

Dr. Galvao and Dr. Otoni (Internal Medicine specialists) have developed and run the Interventional Radiology and Interventional Endoscopy Service at VCA Arboretum View Animal Hospital in Downers Grove, Illinois.

If you have any questions regarding Interventional Radiology and Interventional Endoscopy, please give us a call, we are happy to discuss patients that may benefit from these techniques.
