A retrospective study of 22 animals with histologically confirmed, primary inflammatory brain disease was undertaken to determine the value of computed tomography in such patients. The histologic diagnosis was confirmed at necropsy in 18 patients and by surgical biopsy in four. All affected animals had neurologic deficits; the most common presenting complaint was seizures. Abnormalities were identified on computed tomography images in 21 of the 22 patients. The abnormalities included ventricular changes, falcial deviation, edema, focal changes in parenchymal opacity, focal contrast enhancement, periventricular contrast enhancement, and a ring-like pattern of contrast enhancement. Many lesion types identified in this study, such as falcial deviation, changes in parenchymal opacity, and ring-pattern enhancement, have previously been associated with neoplasia. The abnormalities correlated well with the lesion localization predicted by neurologic examination and confirmed by surgery or necropsy. Although computed tomography findings were often judged to be compatible with inflammatory disease, they did not predict the type of pathologic process. The findings suggest that computed tomography is valuable in the evaluation of animals with primary inflammatory brain disorders, but differentiation of neoplasia from non-neoplastic diseases is not always possible.  相似文献

Respiratory distress is a very common presenting complaint in emergency practice. It is essential that the clinician rapidly determine the underlying cause of the clinical signs using physical examination findings and nonstressful diagnostic tests. Oxygen therapy will often stabilize a patient, allowing for a more complete physical examination and diagnostics, including thoracocentesis, thoracic radiographs, and blood collection for laboratory analysis. The disease processes that cause respiratory distress can be grouped according to anatomic location: the airways, pulmonary parenchyma, pleural space, or thoracic wall. The choice of diagnostic and therapeutic techniques will be dependent on the suspected anatomic origin of disease. Techniques useful in diagnosing airway disorders include oral examination, cervical and thoracic radiographs, fluoroscopy, and bronchoscopy. Therapeutic techniques include intubation and tracheostomy. For parenchymal disease, thoracic radiographs, echocardiography, ultrasound of the thorax, and transtracheal or endotracheal wash can be useful. When the disease process is in the pleural space, thoracocentesis can be both diagnostic and therapeutic. Chest tube placement may be necessary for continuous removal of air or fluid from the pleural space. Monitoring of the respiratory patient can involve serial physical examination, pulse oximetry, and arterial blood gas analysis. It is essential to minimize stress on patients with respiratory distress because decompensation can occur easily, leading to respiratory arrest.  相似文献

Gastrointestinal (GI) disorders including a wide range of infectious, inflammatory, autoimmune, etc. disorders. Inflammatory bowel and celiac disease are non-fatal but overwhelming GI associated disorders. IBD and celiac’s complications, besides the great suffering, disturb the normal life of the patients and make them involved in mental and physical problems. The emerging role of genetic content is deniable for GI inflammatory disorders incidence, and long non-coding RNAs (lncRNAs) function is the recent topic for its association. Analyzing of absolute lncRNAs interference in GI inflammatory appearance remains in infancy, and more studies are requested. Here, we concisely performed a systematic review in the last knowledge up to 2020 to identify all of the significant lncRNAs associated with the initiation and progression of GI inflammatory diseases. Accordingly, this assay attempted to refer to the expression of lncRNAs changing from the normal state, discovery of genetic mechanisms, and main effectors that would trigger associated IBD and celiac expression and immune responses would be effective for therapeutic approaches. It could be useful for prognostic and diagnostic purposes of GI associated inflammatory disorders.  相似文献

Sonographic findings of 18 dogs and four cats with gastrointestinal (GI) diseases were reviewed. Wall thickness, wall layer identification, wall symmetry, extension of the lesion, nature of the GI contents, motility, and regional and/or systemic involvement were recorded for each animal. Ultrasonographic appearance of gastrointestinal neoplasms, gastrointestinal obstruction, ileus, intussusception, inflammatory GI diseases, and congenital disorders are discussed.  相似文献

Diseases of the pleural space are relatively common disorders in small animal clinical practice. The abnormal presence of air, fluid, or tissue within the pleural cavity does not generally reflect disease of the pleura per se; instead, it represents a disorder of the airways or lung parenchyma or the development of a primary systemic illness. This article discusses common causes of the most frequently seen pleural space disorders and outlines general treatment plans that can be used as guidelines when treating actual clinical cases.  相似文献

Exotic small mammal medicine is a relatively new specialty area within veterinary medicine. Ferrets, rabbits, and rodents have long been used as animal models in human medical research investigations, resulting in a body of basic anatomic and physiologic information that can be used by veterinarians treating these species. Unfortunately, there is a paucity of veterinary articles that describe clinical presentation, diagnosis, and treatment options of gastrointestinal (GI) disease as it affects exotic small mammals. Although there is little reference material relating to exotic small mammal GI disease, patients are commonly presented to veterinary hospitals with digestive tract disorders. This article provides the latest information available for GI disease in ferrets (Helicobacter mustelae gastritis, inflammatory bowel disease [IBD], GI lymphoma, systemic coronavirus, coccidiosis, and liver disease), rabbits (GI motility disorders, liver lobe torsion, astrovirus, and coccidiosis), guinea pigs (gastric dilatation volvulus [GDV]), rats (Taenia taeniaeformis), and hamsters (Clostridium difficile). Both noninfectious diseases and emerging infectious diseases are reviewed as well as the most up-to-date diagnostics and treatment options.  相似文献

Glomerular diseases are a leading cause of chronic kidney disease in dogs but seem to be less common in cats. Glomerular diseases are diverse, and a renal biopsy is needed to determine the specific glomerular disease that is present in any animal. Familial glomerulopathies occur in many breeds of dogs. However, most dogs with glomerular disease have acquired glomerular injury that is either immune-complex mediated or due to systemic factors, both of which are believed to be the result of a disease process elsewhere in the body (i.e., neoplastic, infectious, and noninfectious inflammatory disorders). A thorough clinical evaluation is indicated in all dogs suspected of having glomerular disease and should include an extensive evaluation for potential predisposing disorders. Nonspecific management of dogs with glomerular disease can be divided into 3 major categories: (1) treatment of potential predisposing disorders, (2) management of proteinuria, and (3) management of uremia and other complications of glomerular disease and chronic kidney disease. Specific management of specific glomerular diseases has not been fully studied in dogs. However, it may be reasonable to consider immunosuppressive therapy in dogs that have developed a form of glomerulonephritis secondary to a steroid-responsive disease (e.g., systemic lupus erythematosus) or have immune-mediated lesions that have been documented in renal biopsy specimens. Appropriate patient monitoring during therapy is important for maximizing patient care. The prognosis for dogs and cats with glomerular disease is variable and probably dependent on a combination of factors. The purpose of this article is to discuss the general diagnosis and management of dogs with glomerular disease.  相似文献

Ultrasonography may be used to evaluate noninvasively a wide variety of diseases affecting the canine liver. Hepatic mass lesions, parenchymal pathology, gallbladder and biliary disease, and vascular abnormalities may be detected and characterized by ultrasonography. Ultrasonically guided percutaneous liver biopsy can improve the succes and safety of obtaining diagnostic cytologic material. The response of liver disorders to treatment may be effectively monitored by serial ultrasonographic examination. The ultrasonographic diagnosis of canine liver disease is described and illustrated with 11 case history reports.  相似文献

Abstract— In 1956 Sinclair suggested that abnormalities of EFA metabolism might be the basis of many of the unsolved diseases which particularly affect Western societies, notably cardiovascular and inflammatory disorders and cancer. Dismissed as a crank for about 25 years, Sinclair is now being recognised as a percipient pioneer. Recent evidence for the roles of EFAs in cancer, vascular disease, diabetic complications and inflammatory disorders such as atopic eczema and arthritis is discussed.
Resumen  En 1956, Sinclair sugirió que la causa de algunos enfermedades que afectaban al mundo occidental podría ser abnormalidades del metabolismo de los EFA, en particular, enfermedades cardiovasculares, inflamatorias y cancer. Por un periodo de 25 años sus teorías fueron rechazadas, sin embargo hoy se le cdrisidera un pionero en la materia. El reciente descubrimiento del papel de los EFA en cancer, enfermedades cardiovasculares, complicaciones de la diabetes y disórdenes inflamatorios (como arthritis y eczema), se discute en éste artículo.  相似文献

The medical records of 83 horses with pleuropneumonia and/or pulmonary abscessation, in which thoracic sonography was used, were reviewed. The sonograms of these horses were reviewed retrospectively for free gas echoes within pleural or abscess fluid. Anaerobic infection was confirmed in 27 horses, and gas echoes were observed in 21 horses. There was a significant (P less than 0.001) correlation between the observation of gas echoes and anaerobic infection in horses with pleuropneumonia and/or pulmonary abscessation. A foul odor to the breath or pleural fluid was significantly (P less than 0.001) associated with anaerobic infection. Poor survival rates were associated with gas echoes or a foul odor to the breath or pleural fluid, both of which were associated with anaerobic infection. Gas echoes within pleural or abscess fluid were found to be a sensitive and specific indicator of anaerobic infection, as was a putrid odor to the breath or pleural fluid. Evaluation for gas echoes and foul odor had better predictive value than did evaluation for gas echoes or foul odor alone. Gas echoes within pleural or abscess fluid is highly suggestive of anaerobic infection. Ultrasonography should be performed repeatedly in horses with pleuropneumonia to assess the progression or resolution of pleural and parenchymal disease. The detection of gas echoes on subsequent ultrasonograms may indicate the development of anaerobic infection.  相似文献

THE RADIOGRAPHIC APPEARANCE OF PULMONARY HISTOPLASMOSIS IN THE CAT   总被引：1，自引：0，他引：1  
A retrospective study of 18 cats with pulmonary histoplasmosis was conducted to evaluate radiographic patterns of disease and to determine age, breed, and sex distributions. All cats had active disease confirmed by biopsy/aspiration cytology (lung, bone marrow, peripheral lymph nodes, pleural fluid) or necropsy examination. Cats 3 years of age or less had the highest incidence of disease; females outnumbered males 2 to 1. Radiographically, most cats had an interstitial pattern which appeared as a fine, diffuse or linear pattern, or as a more distinct nodular pattern. An alveolar pattern was an uncommon radiographic finding. Tracheobronchial lymphadenopathy and calcified lymph nodes or pulmonary parenchymal lesions were not identified in these cats.  相似文献

Objective ? To describe clinical respiratory parameters in cats and dogs with respiratory distress and identify associations between respiratory signs at presentation and localization of the disease with particular evaluation between the synchrony of abdominal and chest wall movements as a clinical indicators for pleural space disease. Design ? Prospective observational clinical study. Setting ? Emergency service in a university veterinary teaching hospital. Animals ? Cats and dogs with respiratory distress presented to the emergency service between April 2008 and July 2009. Interventions ? None. Measurements and Main Results ? The following parameters were systematically determined at time of admission: respiratory rate, heart rate, temperature, type of breathing, movement of the thoracic and abdominal wall during inspiration, presence of stridor, presence and type of dyspnea, and results of thoracic auscultation. Abdominal and chest wall movement was categorized as synchronous, asynchronous, or inverse. Diagnostic test results, diagnosis, and outcome were subsequently recorded. Based on the final diagnoses, animals were assigned to 1 or more of the following groups regarding the anatomical localization of the respiratory distress: upper airways, lower airways, lung parenchyma, pleural space, thoracic wall, nonrespiratory causes, and normal animals. One hundred and seventy‐six animals (103 cats and 73 dogs) were evaluated. Inspiratory dyspnea was associated with upper airway disease in dogs and expiratory dyspnea with lower airway disease in cats. Respiratory noises were significantly associated and highly sensitive and specific for upper airway disease. An asynchronous or inverse breathing pattern and decreased lung auscultation results were significantly associated with pleural space disease in both dogs and cats (P<0.001). The combination is highly sensitive (99%) but not very specific (45%). Fast and shallow breathing was not associated with pleural space disease. Increased or moist pulmonary auscultation findings were associated with parenchymal lung disease. Conclusions ? Cats and dogs with pleural space disease can be identified by an asynchronous or inverse breathing pattern in combination with decreased lung sounds on auscultation.  相似文献

SUMMARY The metabolism and clinical potential for dietary polyunsaturated fatty acids (PUFAs) modifications using oil supplements containing n-3 and n-6 fatty acids are reviewed. Their use in such disorders as renal disease, inflammatory and immune-related disorders, and dermatological conditions in dogs and cats is discussed. The influence of n-3 fatty acid-rich rations on the endotoxin response in horses is described. Progress has been made toward understanding the clinical potential for PUFAs in these species. However, they have not yet been shown to be efficacious in any of the conditions investigated.  相似文献

Selected equine cutaneous diseases for which there is strong evidence of an immunological aetiology are discussed in this section. The reactive disorders of urticaria, Culicoides hypersensitivity, erythema multiforme, drug eruptions and systemic granulomatous disease are included. The autoimmune diseases of the horse with cutaneous manifestations (pemphigus foliaceus, pemphigus vulgaris, bullous pemphigoid and cutaneous lupus erythematosus) are discussed. The clinical signs and diagnostic features of these immunologically induced equine dermatoses are defined, and the challenges in making a definitive diagnosis and managing the clinical signs are confirmed.  相似文献

The findings of ultrasonography of the gastrointestinal (GI) tract of 265 dogs with GI disorders were analysed retrospectively. The sonographic changes associated with various inflammatory and neoplastic conditions and mechanical obstruction of the GI system were recorded and discussed. Sonographic alterations of the pancreas and the tissues adjacent to the GI tract were also included in the study. Ultrasonographic alterations of the GI tract were classified into three main categories: thickening of the GI wall, changes in peristalsis and dilation of the lumen. Localised thickening of the GI wall with disruption of its structure was caused by both neoplastic diseases and by inflammatory disorders. However, diffuse thickening with retained wall structure was generally associated with inflammatory diseases. The criteria previously established for the ultrasonographic diagnosis of intestinal obstruction were successfully applied to a large number of GI disorders. Pancreatitis was most often associted with hyperchoic mesentery and hypoechoic pancreas mass, but similar alterations were encountered in some cases of gastric or duodenal ulceration. Except in cases of invaginations and intestinal obstructions, the observed ultrasonographic changes were not specific enough for a definitive diagnosis. Nevertheless, ultrasonography proved to be a valuable technique in the diagnostic process of GI disorders of the dog.  相似文献

Acquired portosystemic shunts (PSS) are a clinical entity distinct from congenital PSS. Their apparent incidence in cats is low, which may reflect the rarity of predisposing hepatic parenchymal disease, such as cirrhosis, in this species. Two cats with acquired PSS associated with primary hepatobiliary disease are described. Relevant findings in acquired PSS are discussed, as are potential reasons for the apparently low incidence in the cat.  相似文献

Orbital disease is common in dogs and cats. Clinical signs include exophthalmos, protrusion of the third eyelid, and resistance to retropulsion of the globe. This article discusses diagnostic work-up for dogs and cats with signs suggestive of orbital disease. Diagnosis and treatment of nonneoplastic orbital diseases follows. Congenital diseases are discussed first, followed by inflammatory diseases of the orbit including orbital pseudotumor. Lastly, other less common orbital conditions are addressed.  相似文献

Inhalant exposure to airborne irritants commonly encountered in horse stables is implicated in the pathogenesis of inflammatory airway disease (IAD) and recurrent airway obstruction (RAO), non‐infectious, inflammatory pulmonary disorders that impact the health and performance of horses across all equine disciplines. IAD and RAO have overlapping clinical, cytological, and functional manifestations of the pulmonary response to organic dust and noxious gases encountered in the barn environment. Study of these diseases has provided important but incomplete understanding of the effect of air quality upon the respiratory health of horses. In this review, the principles of particulate exposure assessment, including health‐related aerosol size fractions and size‐selective sampling, the factors influencing air quality in equine environments, and the effect of air quality on the equine respiratory tract are discussed. The objective of this review is to provide the reader with a summary of the most common chronic inflammatory airway diseases in the horse and the principles of air sampling that are essential to the planning, interpretation, and assessment of equine respiratory health‐related exposure studies.  相似文献

In man, the genetic defects of more than 600 inherited diseases, of which at least 150 skeletal diseases, have been identified as is the chromosomal location for approximately 7000 genes. This rapid progress has been made possible by the generation of a genetical and physical map of the human genome. There is no reason to believe that for the dog not a similar development may occur. This review is therefore focussed on the use of novel tools now available for comparative molecular genetic studies of skeletal dysplasias in the dog. Because the genomes of mammals at the subchromosomal level are very well conserved, likely candidate disease genes known from other species might be considered. In this review, formation of the bones and the most important canine disorders of the skeleton influencing locomotion will be discussed first. The canine disorders discussed are canine hip dysplasia, the three different forms of elbow dysplasia (fragmented coronoid process, ununited anconeal process, osteochondrosis dissecans and incongruency) and dwarfism. Where possible a link is made with similar diseases in man or mouse. Then, the molecular biological tools available to analyse the genetic defect will be reviewed and some examples discussed.  相似文献
