    ABSTRACT: Complete situs inversus is a rare congenital condition that is characterized by the development of the thoracic and abdominal viscera in a mirror image to their normal orientation. This study describes this condition in 2 dogs: an 8-year-old male dalmatian that was originally evaluated for cystitis and a 3-year-old male crossbreed Pekinese that had a routine echographic study. In dogs, most of the reported cases were associated with the Kartagener syndrome, but our patients had no evidences of this ciliary disorder.

    ABSTRACT: Primary erythrocytosis, or polycythemia vera, is a myeloproliferative disease caused by the exaggerated increase of erythroid precursor cells in the bone marrow. We report the case of an 11-year-old male mixed-breed dog that had tachypnea and spastic tetraplegia. There was a significant increase in hematocrit. After phlebotomy and fluid therapy, the dog׳s condition improved. A diagnosis of primary erythrocytosis was supported by serum levels of erythropoietin. The dog responded well to treatment with administration of hydroxyurea (15mg/kg), phlebotomies, and fluid therapy. However, after 18 months, he had an acute recurrence of clinical signs and was euthanized. We observed that long-term maintenance with hydroxyurea at a dosage of 15mg/kg every 48 hours was adequate for managing polycythemia vera, with a survival time of 18 months in the present case. However, longer dose intervals are likely not appropriate. We believe that this may be helpful to other veterinarians facing the same problems in the treatment of polycythemia vera.

    ABSTRACT: Pneumopericardium is a rare finding that has been previously reported following spontaneous, traumatic, or iatrogenic causes. A 3-year old Golden Retriever dog was admitted with respiratory distress after falling from a height. Clinical and electrocardiographic findings were nonspecific. Thoracic radiography revealed hyperinflated lung with sharp outlining of the mediastinal structures. A well-demarcated region of radiolucent gas opacity was seen surrounding the cardiac silhouette. Echocardiography revealed intense hyper-reflective shadows all over the heart. Echocardiographic measurements were within the reference range. The dog responded well to conservative medical therapy. Pneumopericardium was reported secondary to pneumomediastinum; pneumopericardium is self-limiting unless other complications develop.

    ABSTRACT: Periodontal diseases (PD) are infectious, inflammatory, progressive diseases of the oral cavity affecting people and dogs. PD takes two forms: gingivitis and periodontitis. Diagnosing and/or staging PD can only be achieved with dental x-rays and periodontal probing, both of which require the use of general anaesthesia in dogs. This study aimed to determine whether serum-ionized calcium (iCa2+) levels can be useful in preliminary PD staging in dogs. A sample of 40 dogs (n = 40) was was divided into four groups (n = 10 each) based on the following PD stages: G1 (gingivitis); G2 (initial periodontitis); G3 (moderate periodontitis); and G4 (severe periodontitis). The groups were then subjected to iCa2+ quantification. Statistically significant differences were observed between PD stages and iCa2+ for all stages except G3 and G4. Therefore, this parameter can be used as an additional tool to establish and monitor preliminary PD status.

    ABSTRACT: Aim To analyse the relationships between gender, age, weight and variations in the levels of serum-ionized calcium ([iCa2+]) during periodontal disease (PD) evolution. Materials and methods In this study, dogs (n = 50) were divided into five groups according to the stage of PD: G0 (no PD), G1 (gingivitis), G2 (initial periodontitis), G3 (moderate periodontitis) and G4 (severe periodontitis). Results Statistically significant correlations were observed between age, iCa2+ levels and PD stage. Conclusion Older individuals had lower iCa2+ levels and more advanced PD stages (high positive correlation), and their body weight decreased as PD developed (negative correlation). Lower iCa2+ values were associated with more severe PD.

    ABSTRACT: Canine nasal and paranasal diseases have variable causes. Presumptive diagnosis is based on clinical manifestations; however, high similarity of clinical signs often calls for diagnostic imaging modalities and rhinoscopy before a definitive diagnosis can be reached. This study sets out to determine the value of rhinoscopy, radiography, and computed tomography (CT) of the head for canine nasal and paranasal disease diagnosis using a purposely developed comparative score. In all, 20 dogs presenting with clinical signs consistent with nasal disease were used. Patients were submitted to radiographic, CT, and rhinoscopic assessment; rhinoscopy-guided biopsy collection was performed in cases presenting with tissue proliferation, ulceration, or other nasal mucosal lesions. Rhinoscopy and rhinoscopy combined with CT significantly contributed to nasal disease diagnosis. Rhinoscopy and CT are complementary diagnostic modalities. Rhinoscopy proved helpful for confirmation of presumptive diagnosis and allowed image-assisted biopsy collection whereas CT contributed to effective determination of lesion extension and involvement of adjacent structures. Yet, histologic confirmation remains vital for definitive diagnosis.

    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: 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: 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: 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: 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: 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.
