    ABSTRACT: A formerly fertile 5-year-old 45-kg Labrador retriever was evaluated for azoospermia noted during routine semen collection for an artificial insemination. Over the past 3 years, the dog had sired 4 litters of anticipated size for the breed out of 5 breedings, the most recent a litter of 10 conceived and whelped 2 months previously. Physical examination findings were normal with the exception of bilaterally small and soft testes. An open excisional wedge biopsy of the right testis was performed under general anesthesia. Histopathology findings supported an immunologic, autoimmune pathogenesis that had resulted in infertility over the previous 4 months. Copyright © 2015 Elsevier Inc. All rights reserved.

    ABSTRACT: Ultrasonography is a valuable diagnostic tool that has been used for diagnosis of neonatal brain diseases. The purpose of the present study was to describe the sequential ultrasonographic appearance of the normal canine neonatal brain from birth till closure of the bregmatic fontanelle. In total, 16 clinically normal neonates of mixed breed dogs were used. The bregmatic fontanelle was used as an acoustic window to record 5 transcranial scans (3 transverse, 1 sagittal, and 1 parasagittal scans) at 3, 10, 20, and 30 days of age. The appearance, echogenicity, and developmental differentiation of the structures within the cranium were described. Good images were obtained at 10 and 20 days of age. At 30 days of age, the obtained images presented poor details, as the fontanelle was small. Data obtained from this study represent the basis of brain ultrasound in neonates until 30 days of age, which could be beneficial in diagnosing congenital brain diseases.

    ABSTRACT: Preterm labor (PTL), myometrial actvity, and accompanying cervical changes can lead to the loss of pregnancy via resorption or abortion before term gestation. Idiopathic PTL has no metabolic, infectious, congenital, traumatic, or toxic cause identified; however, hypoluteoidism has been hypothesized to cause PTL in the bitch, based on progesterone measurements at the time of clinical pregnancy loss. This study documents the use of tocodynamometry to detect PTL in 5 bitches; progesterone measurements in these bitches were normal for pregnancy at the time PTL was diagnosed.

    ABSTRACT: Lumbosacral transitional vertebrae (LTV) frequently occur in German shepherd dogs. The aim of the study was to evaluate the prevalence and interdependence between LTV and canine hip dysplasia (CHD) as well as sacroiliac joint degenerative changes visualized on ventrodorsal radiographs of the pelvis in both working and companion German shepherd dogs. The presence of LTV was found in 12% of working dogs and in 33% of companion dogs. Similar incidence of hip dysplasia in both the groups was found. It has been shown that dogs with LTV have a higher frequency of severe CHD. A higher percentage of sacroiliac joint degenerative changes was observed in dogs with no signs of LTV and in working dogs.

    ABSTRACT: Gastroesophageal intussusception is a rare but life-threatening condition that requires immediate diagnosis and urgent surgical intervention. We describe the clinical, radiographic, ultrasonographic, and gross pathologic examinations of a 50-day-old German Shepherd dog with gastroesophageal intussusception associated with esophageal dilatation. The dog was brought to the clinic 10 days after weaning with a history of regurgitation, persistent vomiting, hematemesis, and dyspnea. On admission, the dog was lethargic with signs of shock and died just before surgery. Gastroesophageal intussusception should be considered in the differential diagnosis in dogs with progressive vomiting or regurgitation especially at the weaning time. Copyright © 2015.

    ABSTRACT: Neonatal veterinarians still observe higher mortality rates among their patients than are observed among in humans. Establishment of a neonatal assessment protocol is fundamental to the identification of the medical status of the neonate and the need for medical intervention. The neonatal Apgar score evaluation, which is commonly used in clinical practice, should be complemented by other methods of analysis. This study proposes, in addition to an Apgar score analysis, the evaluation of laboratory parameters and weight. We believe that knowledge of these reference values is essential for diagnosing at-risk neonates and for establishing suitable treatments.

    ABSTRACT: A 2-year-old intact male South African Boerboel presented for semen cryopreservation and was discovered to be azoospermic. The dog had excellent libido and had sired litters within 6 months, so a further investigation of why his collection lacked sperm was warranted. On further examination of his scrotal contents, his right epididymis had an enlarged area with a hard texture. Ultrasonography revealed that the enlarged area of the right epididymis was fluid filled. A sample of the fluid was aspirated for aerobic culture. No bacteria showed growth. Although the culture was negative, it was suspected that this dog had an epididymitis or epididymal abscess, and treatment with enrofloxacin at 10mg/kg orally was initiated for 4 weeks. The abnormal texture and fluid-filled cavity in the right epididymis persisted, despite antibiotic therapy. Cytology of a repeat aspiration of the fluid-filled area after antibiotic therapy revealed a mixture of red blood cells and sperm. Owing to the potential for blood-testis barrier disruption, a unilateral orchiectomy of the right testicle was performed, as an attempt to protect future sperm production of the remaining testicle. A spermatocele was confirmed on histopathology. After another month, an excellent-quality semen sample was collected, with 90% progressive motility, good concentration, and few morphologic abnormalities. A subsequent collection was acquired and was successfully cryopreserved for future breeding. In dogs with spermatoceles, semen quality can be preserved with aggressive treatment to remove the affected testicle. The disruption of the blood-testis barrier in spermatoceles may result in antisperm antibody production and eventual infertility; however, cryopreservation can result in long-term options for owners seeking to continue using an animal in their breeding program.

    ABSTRACT: The objective of this study was to determine whether healthy dogs undergoing elective surgery will accept and prefer an oral recuperation fluid (ORF) to water during the perioperative time period and if the consumption of an ORF would lead to increased caloric intake during the final preoperative and first postoperative periods. This prospective, observational study was performed in the setting of a University Veterinary Teaching Hospital. A total of 67 healthy dogs were presented for routine ovariectomy (n = 30) or castration (n = 37). Before surgical intervention, dogs were offered an ORF to assess their voluntary acceptance of the fluid. After 2 hours, the ORF was offered alongside water to assess fluid preference. Routine castration or ovariectomy was then performed. During the immediate postoperative period, dogs were reassessed as to their acceptance and preference of the ORF. A high percentage of dogs accepted the ORF in both the preoperative (55/67, 82%) and postoperative (42/67, 63%) periods (P < .01 and P = .04, respectively). Of dogs that demonstrated a preference between the ORF and water, 87% (95% CI: 77%-93%) chose the ORF preoperatively, whereas 98% (95% CI: 87%-99.5%) chose the ORF postoperatively (P < .01 and P < .01, respectively). Dogs that consumed the ORF in each measurement period ingested a higher amount of food (measured as percentage of kilocalories offered) when compared with those that did not consume the ORF (preoperatively 83% vs. 49%, P < .01; postoperatively 51% vs. 27%, P = .01). A commercially manufactured veterinary ORF was found to be palatable, as determined by acceptance and preference testing, in healthy dogs during the preoperative and postoperative phases of routine sterilization. Further studies in dogs undergoing more intensive surgical procedures or recovering from nonsurgical illness or both are warranted. Copyright © 2015 Elsevier Inc. All rights reserved.

    ABSTRACT: To describe the effect of the third-generation gonadotropin-releasing hormone antagonist acyline in the treatment of 4 diestrous bitches with the cystic endometrial hyperplasia-pyometra complex. The 4 bitches were treated with 330μg/kg of subcutaneous acyline on day 0 and antibiotics, and followed up for 2 weeks. One closed-cervix case showed cervical dilatation 36 hours after treatment, and all the 4 animals showed resolution of clinical signs starting on day 3 posttreatment. Ultrasonographic uterine diameters and luminal contents decreased in the bitches having high progesterone serum concentrations before treatment but not in those with low levels. Serum progesterone importantly decreased from high to basal concentrations in the 3 "ultrasonographically cured" animals. No local or systemic side effects related to the treatment were observed. The gonadotropin-releasing hormone antagonist acyline may have a promising place for the medical treatment of cystic endometrial hyperplasia-pyometra complex in dogs. Copyright © 2015 Elsevier Inc.

    ABSTRACT: Canine flotation devices (CFDs) are very popular; however, their efficacy is still under debate. There is no oversight to standardize device testing, certification, or qualification for use. We set out to assess the biomechanical and behavioral effects of 3 CFDs on swim and flotation characteristics of dogs. High-speed video recordings were used to measure behavior, range of motion (ROM), maximum flexion angle, and cycles of motion per minute while swimming and roll, yaw, and fear or panic scoring while floating. Predictably, swimming with no CFD yielded the largest ROM and flexion angles. CFDINF was associated with the least ROM. During flotation, CFDAB and CFDRW caused significant rolling and fear, whereas CFDINF was the most stable. CFDAB was associated with cranial downpitch in 2 dogs. Interpretation of the kinematics for CFDAB and CFDRW suggests that decreased stability in the water leads to a greater forced ROM when the position of the dog was conducive to swimming. When positioning forced the dog into a downward pitch, ROM was decreased because of the increased effort for the dogs to keep their head above water. CFDINF was most stable overall owing to a decreased swim effort, with most dogs showing the lowest fear scores and absolute relaxation. CFDAB and CFDRW caused the dogs significant rolling, fear, and distress, with obvious fighting of sedation. We hope to disseminate these results to dog owners in the hopes of providing a valid assessment of these devices. Copyright © 2014 Elsevier Inc. All rights reserved.

    ABSTRACT: Phenobarbital-responsive sialadenosis (PRS) is a rare idiopathic disease in dogs. Vomiting, retching, and gulping with bilateral enlargement of the submandibular salivary glands are the more frequent clinical signs. A thorough diagnostic examination must be performed to rule out the most important systemic etiologies involved with chronic vomiting, as there is no specific test to diagnose PRS. Diagnosis is confirmed clinically by a rapid and dramatic improvement of clinical signs after instauration of phenobarbital treatment. The aim of this article is to describe the clinical presentation, diagnostic findings, and outcome of a case series of 4 dogs with presumptive PRS. Copyright © 2015 Elsevier Inc. All rights reserved.

    ABSTRACT: A 6-year-old, large-breed, female dog was evaluated for gastric dilatation (GD). The dog was affected by GD volvulus, which had been surgically treated with gastric derotation and right incisional gastropexy. Recurrence of GD appeared 36 hours after surgery. The dilatation was immediately treated with an orogastric probe but still recurred 4 times. Therefore, a left-side gastropexy by percutaneous endoscopic gastrostomy (PEG) was performed to prevent intermittent GD. After PEG tube placement, the patient recovered rapidly without side effects. Several techniques of gastropexy have been described as a prophylactic method for gastric dilatation volvulus, but to the authors׳ knowledge, this is the first report of left-sided PEG gastropexy performed in a case of canine GD recurrence after an incisional right gastropexy.

    ABSTRACT: Hypoadrenocorticism is an uncommon disease in dogs and rare in humans, where it is known as Addison disease (ADD). The disease is characterized by a deficiency in corticosteroid production from the adrenal cortex, requiring lifelong hormone replacement therapy. When compared with humans, the pathogenesis of hypoadrenocorticism in dogs is not well established, although the evidence supports a similar autoimmune etiology of adrenocortical pathology. Several immune response genes have been implicated in determining susceptibility to Addison disease in humans, some of which are shared with other autoimmune syndromes. Indeed, other types of autoimmune disease are common (approximately 50%) in patients affected with ADD. Several lines of evidence suggest a genetic component to the etiology of canine hypoadrenocorticism. Certain dog breeds are overrepresented in epidemiologic studies, reflecting a likely genetic influence, supported by data from pedigree analysis. Molecular genetic studies have identified similar genes and signaling pathways, involved in ADD in humans, to be also associated with susceptibility to canine hypoadrenocorticism. Immune response genes such as the dog leukocyte antigen (DLA) and cytotoxic T-lymphocyte-associated protein 4 (CTLA4) genes seem to be particularly important. It is clear that there are genetic factors involved in determining susceptibility to canine hypoadrenocorticism, although similar to the situation in humans, this is likely to represent a complex genetic disorder.

    ABSTRACT: Gastric dilatation-volvulus (GDV) is a common and catastrophic disease of large and giant breed dogs. Treatment of GDV includes medical stabilization followed by prompt surgical repositioning of the stomach in its normal anatomic position. In order to prevent reoccurrence, gastropexy is used to securely adhere the stomach to the body wall. Effective gastropexy decreases the recurrence of GDV from as high as 80% to less than 5%. The purpose of this article is to describe the history, indications and techniques for gastropexy. Gastropexy was first reported in veterinary medicine in 1971 for management of gastric reflux, and later in 1979 for treating and preventing the recurrence of GDV. Gastropexy is indicated in all dogs that undergo surgical correction of GDV. Additionally, prophylactic gastropexy should be strongly considered at the time of surgery in dogs undergoing splenectomy for splenic torsion and potentially other splenic pathology, and in dogs of at-risk breeds, such as Great Danes, that are undergoing exploratory celiotomy for any reason due to evidence for increased risk of GDV in these patients. While there are numerous techniques described, gastropexy is always performed on the right side of the abdomen, near the last rib. Ensuring an anatomically correct gastropexy location is vital to prevent post-operative complications such as partial pyloric outflow obstruction. Gastropexy can be performed as part of an open surgical approach to the abdomen, or using a minimally invasive technique. When combined with surgical correction of GDV, gastropexy is almost always performed as an open procedure. The stomach is repositioned, the abdomen explored, and then a permanent gastropexy is performed. Techniques used for open gastropexy include incisional, belt-loop, circumcostal, and incorporating gastropexy, as well as gastrocolopexy. Each are described below. Incisional gastropexy is currently the most commonly performed method of surgical gastropexy in dogs; it is quick, relatively easy, safe and effective. Minimally invasive techniques for gastropexy are often used when gastropexy is performed as an elective, isolated procedure. Minimally invasive techniques include the grid approach, endoscopically guided mini-approach and laparoscopic gastropexy. Laparoscopic gastropexy is the least invasive alternative, however requires special equipment and significant surgical expertise to perform. The authors consider it a veterinarians responsibility to educate the owners of at-risk large and giant dog breeds about prophylactic gastropexy given such a favorable risk: benefit profile.

    ABSTRACT: Gastric dilatation-volvulus (GDV) is a devastating disease that most commonly affects large and giant-breed dogs. Though a number of risk factors have been associated with the development of GDV, the etiology of GDV remains unclear. Abnormal gastric motility patterns and delayed gastric emptying have been previously described in dogs following GDV. Work evaluating the effects of gastropexy procedures and changes to gastric motility after experimental GDV has not found the same changes as those found in dogs with naturally-occurring GDV. While the role of abnormal gastric motility in dogs with GDV will need to be clarified with additional research, such study is likely to be facilitated by improved access to and development of noninvasive measurement techniques for the evaluation of gastric emptying and other motility parameters. In particular, the availability of FDA-approved wireless motility devices for the evaluation of gastrointestinal motility is particularly promising in the study of GDV and other functional gastrointestinal diseases of large and giant breed dogs.
