    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: 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: 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: Emergencies involving the crystalline lens are not common; however, their clinical signs must be recognized quickly to begin treatment or referred immediately to improve the chances of retaining sight. The lens is a unique structure because of its immunologically privileged status and its imperative clarity for vision. Any insult to the lens capsule's integrity, its position within the globe, or to its clarity may result in undesirable sequelae.

    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 and feline glaucomas are commonly presented as ocular emergencies. Glaucoma is a common cause of vision loss and a frustrating disorder in terms of medical and surgical treatment. Increased intraocular pressure (IOP) is a significant risk factor in the disease, leading to damage of the retina and optic nerve head. IOP measurement and gonioscopic and fundic examinations provide the instruments for diagnosis of glaucoma. The primary goal in glaucoma therapy is aimed at vision preservation. Medical treatment provides temporary relief, but alone it fails to control IOP in the long term, and surgical intervention is recommended. Surgical patient selection depends on several factors, from type and stage of glaucoma to the presence of or potential for vision. Available surgical procedures to decrease IOP consist of cyclodestructive techniques to decrease aqueous humor production and filtering techniques to increase its drainage. Even with recent surgical and medical advances, pain and blindness are still common occurrences in the disease: end-stage procedures such as enucleation, evisceration with intrascleral prosthesis, and pharmacologic ablation of ciliary bodies are then recommended to address chronic discomfort for buphthalmic and blind globes.

    ABSTRACT: Sudden loss of vision is an ophthalmic emergency with numerous possible causes. Abnormalities may occur at any point within the complex vision pathway, from retina to optic nerve to the visual center in the occipital lobe. This article reviews specific prechiasm (retina and optic nerve) and cerebral cortical diseases that lead to acute blindness. Information regarding specific etiologies, pathophysiology, diagnosis, treatment, and prognosis for vision is discussed.

    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: 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.
