After a complete diagnostic work-up and history it is suspected that our patient’s infliction is Canine Lyme nephritis. Lyme disease causative agent is Borrelia burgdorferi that is transmitted by arthropod vectors, most notably the Ixodes ticks. 2,4,6 The most frequent presentation of canine Lyme disease is an acute monoarthritis or polyarthritis often without any systemic clinical signs. A presumptive diagnosis of Lyme disease can be made with a positive Lyme ELISA test that is followed with a positive quantitative C6 ELISA and/or a positive multiplex test after clinical signs and history raise suspicion of the disease.2,6 Over the last few years the atypical presentation of Lyme nephritis seems to be increasing in frequency. Lyme nephritis can presents as an acute renal injury evident by a protein-losing nephropathy.6,7 Acute renal injury clinical signs typically include: lethargy, polyuria, polydipsia, dehydration, and anorexia.6 Diagnostic tests usually reveal a severe azotemia, hyperphosphatemia, hypoalbuminemia, a metabolic acidosis, and positive Lyme ELISA and C6 quantitative ELISA tests.6 Renal biopsies combined with suggestive diagnostic tests, are necessary for definitive diagnosis of Lyme nephritis and reveal a glomerulonephritis, diffuse tubular necrosis therefore showing tubular casts, and interstitial lymphoplasmocytic inflammation.2 These pathologic changes are irreversible as well as the resulting renal failure, ultimately ending in death. A renal biopsy was not performed on in this case therefore a definitive diagnosis of Lyme nephritis is unable to be made. However, with all the other suggestive clinical signs and diagnostic tests it was highly suspected that our case was a case of Lyme nephritis. 2013-01-30T00:00:00Z http://hdl.handle.net/1813/33252 Title: Respiratory disease in a Holstein calf with investigation of the herd management Authors: Linden, Tom Abstract: On September 27th, 2012 a 3-week old Holstein heifer calf presented to the Cornell University Equine and Farm Animal Hospital for an approximately one week history of coughing, decreased appetite, diarrhea, and fever. This calf was one of six, high genetic value, in vitro fertilization (IVF) calves on the farm showing similar signs. All calves were unresponsive to multiple antimicrobials. On arrival, a resulting physical and thoracic ultrasound examination yielded a problem list including fever, diarrhea, and respiratory disease. In addition, other calves had swollen joints and umbilici. A subsequent diagnostic plan revealed several infectious agents present on the farm. Due to the nature of the case, an Animal Health Diagnostic Center (AHDC) Extension Veterinarian conducted an interview of the herd veterinarian and performed a herd visitation. Key herd management issues were identified. As a result, recommendations were made to increase passive transfer in animals, improve housing and feed management, and create working standard operating procedures. 2013-01-30T00:00:00Z http://hdl.handle.net/1813/33251 Title: Reproduction techniques in an infertile mare Authors: Morrissey, Jennifer K. Abstract: A 15 year old hunter-under-saddle Thoroughbred Mare presented to Cornell University’s Theriogenology Service for a two year history of an inability to maintain pregnancy. The mare had previously delivered seven foals successfully, but had begun having a variety of reproductive issues starting in 2009. These issues included endometritis, a rectal tear, and delayed embryological development. Upon presentation in May of 2012, the mare was bright, alert and responsive with all vital signs within normal limits and was of good body condition (5/9). A breeding soundness exam revealed the following: she was creating and ovulating normal follicles; her hormones were at appropriate levels; her endometrium had a biopsy score of 2A (suggesting a 50-70% chance of carrying any foal conceived to term); her uterine culture and cytology were clear; no abnormalities to her reproductive tract were seen or palpated other than a permanent Caslick’s in place due to poor perineal conformation.5 To further evaluate the problem, the mare was bred to a known, fertile stallion and did not conceive. The mare was then bred to a known, fertile stallion and an embryo flush was performed with no embryo obtained. These steps helped determine that it was not a stallion issue. Based on the breeding soundness exam and the stallion findings, it was deduced that the mare’s infertility was most likely due to a uterine tubal motility or blockage issue that was preventing the zygote from traveling down the tube and settling in the uterus. In an attempt to obtain a foal from this mare, it was decided that she should undergo oocyte transfer and that her daughter would be used as the oocyte recipient. The mare was sedated and placed in stocks. To obtain the oocytes, a transvaginal ultrasound-guided approach was used and only pre-ovulatory follicles were targeted. A double-lumen aspiration needle was used to allow lavage of the follicle – maximizing the likelihood of obtaining an oocyte. The recovered fluid was examined under microscope but no oocytes were obtained. The lateness of the breeding season prevented further investigation at this point. Mares with tubal infertility are candidates for a procedure known as laparoscopic prostaglandin E2 (PGE2) application. In this procedure, a sterile embryo transfer pipette is used during a laparoscopic procedure to place a gel form of PGE2 on the dorsal surface of the uterine tube. This allows the smooth musculature of the uterine tube to relax and increases transport through the tube. The theory is to allow debris that has accumulated in the uterine tube to clear into the uterus. While uncontrolled, a preliminary study performed in 2005 suggested that this technique could have up to a 93% success rate of conception of a pregnancy up to two years post application. The mare in this study underwent this procedure in January of 2013. 2013-01-23T00:00:00Z http://hdl.handle.net/1813/33250 Title: Pulmonic stenosis in a one-year-old male castrated Jack Russell Terrier Authors: Zager, Erik Abstract: A one-year-old Jack Russell Terrier was referred to Cornell University Hospital for Animals’ Cardiology service for work-up of a murmur and chylothorax after a single incident of respiratory distress. The dog had a heart-murmur diagnosed shortly after birth and did not experience any clinical signs until one year of age. An echocardiogram revealed severe pulmonic stenosis with a right atrium to pulmonary artery pressure gradient of greater than 200mmHg. No cause for the chylothorax was identified. A balloon valvuloplasty was performed and the pressure gradient was reduced to 93mmHg. The patient developed a right atrial thrombus and was placed on clopidogrel. Informal follow up revealed the patient was alive and without clinical signs at six months postoperative. 2013-01-23T00:00:00Z http://hdl.handle.net/1813/33249 Title: Patent ductus arteriosus repair Authors: Ostreich, Amy Abstract: A 4-month-old, intact female, Border Collie Presented to Cornell’s Cardiology service on 11/7/12 after her referring veterinarian diagnosed a murmur at an initial puppy exam.

The patient, an 11-year-old female spayed English springer spaniel, presented to the Cornell University Hospital for Animals’ Internal Medicine Service for evaluation of a three-month history of coughing. After ruling out various causes of a cough, sedated oral examination revealed a necrotic lesion caudal to the left maxillary first molar that was clinically diagnosed as maxillary osteonecrosis. Surgical treatment consisting of sequestrectomy and debridement was performed, followed by long-term targeted antibiotic therapy, antiseptic oral rinses, and pain management. 2013-01-23T00:00:00Z http://hdl.handle.net/1813/33247 Title: Pancreatic pseudocyst and pleural effusion as sequelae to pancreatitis in a dog Authors: LaPorta, Katherine G. Abstract: <Dog’s name> an adult, female spayed Yorkshire Terrier presented to the Cornell University Small Animal Clinic on September 28, 1994. The dog had been treated successfully two weeks prior for pancreatitis. Based on clinical signs, blood work, radiographs and ultrasound, a diagnosis was made of an acute relapse of pancreatitis due to lack of owner compliance to diet changes. <Dog’s name> developed two rare complications of pancreatitis while being treated at Cornell: pancreatic pseudocyst and pleural effusion. The pancreatic pseudocyst was diagnosed and monitored with abdominal ultrasound. Based on serial monitoring of the pseudocyst with ultrasound, surgery was performed and the cyst was drained. The pleural effusion resolved with tapered fluid and diuretic therapy. <Dog’s name> is now doing well at home and is maintained on a low fat home cooked diet. 1995-03-15T00:00:00Z http://hdl.handle.net/1813/31570 Title: Theiler’s disease Authors: Wooding, M. B. Abstract: The incidence of Theiler's disease is rather low, but the disease is one that is likely to appear in any horse practice and it is well that every practitioner should know about it so that he will not become confused when it appears. It is my purpose to present a typical case and to explain the circumstances under which the disease can occur so that every practitioner will be alert to the possibilities of it in cases of nervous, icteric syndromes in horses. The case in point concerns a 12 year old bay saddle mare. 1961-01-01T00:00:00Z http://hdl.handle.net/1813/31339 Title: Theilers disease: equine serum hepatitis Authors: Brinkmann, Ted Abstract: This case concerns a black 25 year old gelding...On the basis of lab tests and clinical signs the diagnosis of Theilers disease - hepatic encephalopathy (other) was made. 1971-01-01T00:00:00Z
