    ABSTRACT: Serological tests are used widely in veterinary practice; most often in the diagnosis of infectious disease. Such tests may be used to detect antigen from an infectious agent within a biological sample or to detect the presence of serum antibody specific for the pathogen as evidence of immunological exposure. These tests are all based on the fundamental principles of interaction between antigenic epitopes and antibodies of either the immunoglobulin (Ig) G, IgM, IgA, or IgE classes. The relative concentration of specific antibody within a sample is traditionally determined by calculation of the titer of antibody. With few exceptions, the primary interaction between an antigen and antibody in vitro cannot be visualized and so serological tests generally employ a secondary indicator system based on the use of a polyclonal antiserum or monoclonal antibody. A range of such tests has been developed, but many in veterinary medicine are based on the principle of the enzyme-linked immunosorbent assay, which is described in detail in this article. The interpretation of serological tests must be made carefully, taking into consideration the sensitivity and specificity of the test and the possible reasons for false-positive and false-negative outcomes.

    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: 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: Corneal emergencies can be due to a number of different causes and may be vision threatening if left untreated. In an attempt to stabilize the cornea, it is of benefit to place an Elizabethan collar on the patient to prevent further corneal damage. This article discusses the diagnosis, prognosis, and management of corneal emergencies in dogs and cats.

    ABSTRACT: Orbital diseases are common in dogs and cats and can present on emergency due to the acute onset of many of these issues. The difficulty with diagnosis and therapy of orbital disease is that the location of the problem is not readily visible. The focus of this article is on recognizing classical clinical presentations of orbital disease, which are typically exophthalmos, strabismus, enophthalmos, proptosis, or intraconal swelling. After the orbital disease is confirmed, certain characteristics such as pain on opening the mouth, acute vs. chronic swelling, and involvement of nearby structures can be helpful in determining the underlying cause. Abscesses, cellulitis, sialoceles, neoplasia (primary or secondary), foreign bodies, and immune-mediated diseases can all lead to exophthalmos, but it can be difficult to determine the cause of disease without advanced diagnostic imaging, such as ultrasound, magnetic resonance imaging, or computed tomography scan. Fine-needle aspirates and biopsies of the retrobulbar space can also be performed.

    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: 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: Melanocytic neoplasms in veterinary species occur in various ophthalmic locations including the eyelid, conjunctiva, cornea, sclera, anterior and posterior uvea, and orbit. Histology usually provides the definitive diagnosis for melanocytic ocular neoplasias. The degree of tissue invasiveness and anaplastic cellular characteristics are more reliable indicators of biological behavior than is mitotic index in most ophthalmic melanocytic tumors. Melanocytic neoplasias of the eyelid are predominantly benign in canines and equines, though in felines, there is the potential for metastasis, especially if the conjunctiva is involved. Limbal melanocytic tumors are predominantly benign in all the studied species, though there is a bimodal occurrence with this tumor type in canines, where those that appear in dogs younger than 4 years tended toward active growth, whereas those that appear in dogs older than 8 years tended to progress more slowly, and may not require therapy. The most common location for melanocytic ocular neoplasias in both canines and felines is the anterior uvea. Feline diffuse iris melanoma in particular has a higher incidence of metastasis than does canine nodular anterior uveal melanocytoma. In contrast, posterior uveal melanocytic tumors are rare in both canine and feline species and are considered benign. Orbital melanoma is rare in both canine and feline species; however, it generally carries a grave prognosis owing to its malignant nature. Knowledge of the general biological behavior and its variability among locations within the eye and between species is essential in therapeutic planning.

    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.
