Atypical myopathy is highly fatal, but about a quarter of affected horses survive. This highlights the need for provision of supportive treatment for these patients. This review is a practical guideline for equine practitioners and includes suggestions for close monitoring of involved organ systems and discusses options of supportive treatment based on current knowledge of the condition. Part 2 covers the muscular, urinary, respiratory and hepatic systems, and the general inflammatory/infectious status of the case. 相似文献

A case of bilateral, upper urinary tract infection caused by haemolytic E coli in a female Birman cat is presented. Ultrasonographic examination of the kidneys documented changes in size, outline, echogenicity and architecture. Ultrasound guided fine needle aspiration of fluid from the renal pelvis was used to make the diagnosis. Fluid was submitted for culture and sensitivity and based on the results, antimicrobial therapy was initiated. The treatment was monitored over a 406-day follow-up period. Despite extensive treatment with specific antibiotics and supportive therapy, recurrence of urinary tract infection occurred. 相似文献

This report offers a consensus opinion on the diagnosis, epidemiology, treatment, and control of the primary enteropathogenic bacteria in dogs and cats, with an emphasis on Clostridium difficile, Clostridium perfringens, Campylobacter spp., Salmonella spp., and Escherichia coli associated with granulomatous colitis in Boxers. Veterinarians are challenged when attempting to diagnose animals with suspected bacterial-associated diarrhea because well-scrutinized practice guidelines that provide objective recommendations for implementing fecal testing are lacking. This problem is compounded by similar isolation rates for putative bacterial enteropathogens in animals with and without diarrhea, and by the lack of consensus among veterinary diagnostic laboratories as to which diagnostic assays should be utilized. Most bacterial enteropathogens are associated with self-limiting diarrhea, and injudicious administration of antimicrobials could be more harmful than beneficial. Salmonella and Campylobacter are well-documented zoonoses, but antimicrobial administration is not routinely advocated in uncomplicated cases and supportive therapy is recommended. Basic practices of isolation, use of appropriate protective equipment, and proper cleaning and disinfection are the mainstays of control. Handwashing with soap and water is preferred over use of alcohol-based hand sanitizers because spores of C. difficile and C. perfringens are alcohol-resistant, but susceptible to bleach (1:10 to 1:20 dilution of regular household bleach) and accelerated hydrogen peroxide. The implementation of practice guidelines in combination with the integration of validated molecular-based testing and conventional testing is pivotal if we are to optimize the identification and management of enteropathogenic bacteria in dogs and cats. 相似文献

Over the past 20 years, the conception of brain development has radically changed from a fixed and limited hierarchical process to a more plastic and continuous one. Most surprising, the field has learned that postnatal neurogenesis is not just a seasonal phenomenon in songbirds but a process that occurs across species and seasons. Astrocytes, whose primary role in the central nervous system was thought to be strictly supportive, have emerged as a heterogeneous population, a subset of which is the neural stem cell. Postnatal neurogenesis persists in specialized niches within the rostral subventricular zone and hippocampal dentate gyrus and, for a limited period, within the white matter tracts and external granular layer of the cerebellum. These specialized microenvironments are influenced by factors in the blood, cerebrospinal fluid, and local extracellular matrix. This article reviews the current understanding of adult neurogenesis, which is conserved across many vertebrate species, underscoring the value of animal models in past and present studies of human neurogenesis and neurogenic disease. 相似文献

Objective: To review the pathophysiology, clinical signs, diagnosis, and current treatment modalities used in treating tetanus in small animals and humans. Etiology: Tetanus is caused by the activity of a toxin released from the bacterial organism, Clostridium tetani. The disease has an incubation period of 3 days to 3 weeks and usually follows a deep penetrating wound. Diagnosis: The diagnosis of tetanus is usually based on history and clinical signs. Therapy: Therapy of tetanus consists of direct and supportive care and includes toxin neutralization via human or equine derived immunoglobulin, antimicrobial therapy to eliminate C. tetani, and central and peripheral muscle relaxants to control hypertonicity. Adjunctive care may include positive pressure ventilation, anticonvulsant medication, drugs to treat autonomic dysfunction, and nutritional support. Prognosis: Prognosis varies based on severity of clinical signs at the time of diagnosis and the availability of appropriate care. 相似文献

Rodents may be presented on an emergency basis with various conditions causing debilitation and disease. Common causes of emergent presentations include trauma, respiratory disease, dental disease, gastrointestinal disease, reproductive disorders, and urinary tract obstruction. Emergency treatment should always include immediate stabilization of the patient until the patient is able to tolerate diagnostic testing and additional therapeutics. Rodent patients benefit from supportive care, including thermal, fluid, and nutritional support. Administration of cardiopulmonary resuscitation, antibiotics, and analgesics through various routes is also appropriate. This article presents an overview of emergency medicine in rodents, including emergency procedures, handling and restraint, triage and patient assessment, sample collection, and supportive care procedures. The most common emergency presentations for rodents are also discussed. 相似文献

The aim of this review is to provide a comprehensive update on the biology, epidemiology, clinical features, diagnosis, treatment, and prevention of canine cardio-pulmonary angiostrongylosis. This cardiopulmonary disease is caused by infection by the metastrongyloid nematode Angiostrongylus vasorum. The parasite has an indirect life cycle that involves at least two different hosts, gastropod molluscs (intermediate host) and canids (definitive host). A. vasorum represents a common and serious problem for dogs in areas of endemicity, and because of the expansion of its geographical boundaries to many areas where it was absent or uncommon; its global burden is escalating. A. vasorum infection in dogs can result in serious disorders with potentially fatal consequences. Diagnosis in the live patient depends on faecal analysis, PCR or blood testing for parasite antigens or anti-parasite antibodies. Identification of parasites in fluids and tissues is rarely possible except post mortem, while diagnostic imaging and clinical examinations do not lead to a definitive diagnosis. Treatment normally requires the administration of anthelmintic drugs, and sometimes supportive therapy for complications resulting from infection. 相似文献

Previously, antioxidants have not been evaluated for treatment of parvoviral diarrhea in dogs. In this study, antioxidant potential of N‐acetylcysteine (NAC) in dogs infected with canine parvovirus with a nonblinded randomized clinical trial has been carried out. A total 18 parvo‐infected dogs were randomly divided into two groups: nine parvo‐infected dogs were treated with supportive treatment and nine parvo‐infected dogs were treated with NAC along with supportive treatment. Simultaneously, nine healthy dogs were kept as healthy control. In parvo‐infected dogs, marked hemoconcentration, leucopenia, neutropenia and oxidative stress were noticed compared to healthy dogs. The NAC treatment progressively improved the leukocyte, neutrophil, monocyte, and eosinophil counts over the time in parvovirus‐infected dogs compared to dogs that received only supportive treatment. In addition, NAC treatment significantly improved glutathione S‐transferase (GST) activity and decreased nitrite plus nitrate (NOx) and malondialdehyde (MDA) concentrations on day 3 and 5 compared to supportive treatment in parvo‐infected dogs. However, supportive treatment alone failed to ameliorate oxidative stress in the infected dogs till day 5. The results of this study suggest that NAC represents a potential additional treatment option that could be considered to improve the health condition and minimize the duration of hospitalization in case of canine parvoviral diarrhea. 相似文献

Radiation therapy is becoming increasingly more available and in demand for small animal veterinary cases. Although there is a demand for radiation therapy in large animal cases, there are certain limitations of external beam radiation therapy for horses that restrict treatment options. Currently, there are only five veterinary teaching hospitals in the United States where external beam radiation therapy can be performed on horses and other large animals. This is in contrast to the roughly 80 facilities, both academic and private, available for small animals. The goal of this commentary is to give a brief overview of external beam radiation therapy and highlight the steps involved, and the technical difficulties faced, while treating horses with external beam radiation therapy. 相似文献

Photodynamic therapy: basic principles and potential uses for the veterinary ophthalmologist 总被引：1，自引：1，他引：0
Photodynamic therapy (PDT) involves the use of photochemical reactions mediated through the interaction of photosensitizing agents, light and oxygen. PDT, while now commonly used in physician ophthalmology and oncology, is uncommonly used for the veterinary ophthalmic patient. It is an emerging new therapy in veterinary ophthalmology for the treatment of periocular tumors. This article reviews the basic principles of PDT to provide the veterinary ophthalmologic community with a succinct reference for this emerging treatment modality in our field. 相似文献

Wound healing, although similar to terrestrial vertebrates, occurs faster in fish species in a proper aquatic environment. Wound management must involve identification and correction of potential noninfectious and/or infectious causes of disease. Wound evaluation includes assessment of the wound as well as systematic examination of the patient, water quality conditions, and husbandry practices. Diagnostic evaluation should, at a minimum, include physical examination, skin/cornea (if indicated) scraping, and lesions cultures. The clinician should also consider full thickness wound biopsies, gill and fin biopsies, blood collection, and radiographs for systemic evaluation as well. Local wound management should follow basic principles of wound care including cleaning and lavage, debridement, primary closure if indicated, and local and/or systemic antiinfectives. Monofilament absorbable or nonabsorbable sutures are commonly used for primary closure of wounds. Diagnostic results, patient and client compliance, and economic impact should guide systemic methods of treatment for wound care. Options for systemic therapy include oral or gavage, parenteral, bath, or prolonged immersion treatments. With bath or prolonged immersion therapies, aquatic systems must be properly prepared for treatment. Treatment of identified pathogens, proper water quality and husbandry, supportive care and nutrition must all be provided to promote an ideal wound healing environment for the teleost fish. 相似文献

Objective: To review and summarize current information regarding epidemiology, risk factors, and pathophysiology associated with canine parvoviral infection, and to outline diagnostic and treatment modalities for this disease. Preventative and vaccination strategies will also be discussed, as serologic documentation of immunocompetence and adoption of safe and effective vaccination protocols are crucial in limiting infection and spread of canine parvoviral enteritis. Etiology: Parvoviruses (Parvoviridae) are small, nonenveloped, single‐stranded DNA viruses that replicate in rapidly dividing cells. Canine parvovirus 2 (CPV‐2) remains a significant worldwide canine pathogen and the most common cause of viral enteritis in this species. Diagnosis: Classic presentation of CPV infection includes acute‐onset enteritis, fever, and leukopenia. Definitive diagnostic tests include detection of CPV in the feces of affected dogs, serology, and necropsy with histopathology. Therapy: Standard therapeutic practices for both mildly and severely affected puppies will be discussed. The ability of this virus to incite not only local gastrointestinal injury, but also a significant systemic inflammatory response has recently been reviewed in the literature, and novel innovative experimental and clinical therapeutic strategies, such as antagonism of proinflammatory cytokines and immunostimulation, are introduced in this article. Prognosis: CPV remains a significant worldwide canine pathogen. In experimentally affected dogs, mortality without treatment has been reported as high as 91%. However, with prompt recognition of dogs infected with CPV‐2, and aggressive in‐hospital supportive therapy of severely affected puppies, survival rates may approach 80–95%. 相似文献

Groups of seven cattle were infected with Theileria parva stabilate and treated with parvaquone (20 mg kg-1 bodyweight) zero, four, eight, 12, 14 or 16 days after infection. Very early treatments resulted in a rapid recovery or no detectable parasitosis and some cattle were subsequently susceptible to homologous challenge. Treatments applied before extensive lymphoid or other organ damage had developed were successful and some cattle treated in advanced disease also recovered. Clinical pathological indications of liver or kidney damage were recorded very late in the disease suggesting that prompt diagnosis and treatment are more important than supportive therapy for survival. Treatment on day 8 after infection allowed the appearance of macroschizonts and a transient pancytopenia but no other disease signs. This group was solidly immune to challenge and this timing and treatment could be recommended for use in an infection and treatment method of immunisation. 相似文献

Feline herpesvirus type 1 (FHV-1) infection, but not necessarily chronic or recurrent disease, is common throughout domestic cat populations worldwide. Knowledge of a few essential virological facts permits practitioners to provide appropriate advice to owners of individual pet cats infected with this virus and to assist in the management of shelters and other multicat households in which the virus is enzootic. This article discusses pathogenesis, diagnostic techniques, and clinical signs considered characteristic of infection with FHV-1. Treatment options are considered under the broad categories of supportive care, antiviral agents, and adjunctive therapies. 相似文献

Feline heartworm disease is caused by the filarial nematode Dirofilaria immitis, and is transmitted by mosquitoes in heartworm-endemic areas worldwide. While dogs are the definitive hosts for this parasite, cats can also be infected, and the overall prevalence in cats is between 5% and 10% of that in dogs in any given area. The spectrum of feline presentations varies from asymptomatic infections to chronic respiratory signs, sometimes accompanied by chronic vomiting to acute death with no premonitory signs. Ante-mortem diagnosis can be challenging and relies on a combination of tests, including antigen and antibody serology, thoracic radiography and echocardiography. As treatment with heartworm adulticidal drugs can be life-threatening and heartworm infection in cats is often self-limiting, infected cats are frequently managed with supportive treatment (corticosteroids, bronchodilators, and anti-emetics). Surgical removal of filariae using extraction devices may be considered in some acute cases where immediate curative treatment is necessary, but filarial breakage during the procedure may result in an acute fatal shock-like reaction. Necropsy findings are mainly pulmonary and include muscular hypertrophy of the pulmonary arteries and arterioles on histopathology. A number of safe and effective macrocytic lactone drugs are available for prophylaxis in cats. These drugs can kill a range of larval and adult life-cycle stage heartworms, which may be advantageous in cases of owner compliance failure or when heartworm infection status is undetermined at the time prophylaxis is commenced. An index of suspicion for feline heartworm disease is warranted in unprotected cats with respiratory signs, and perhaps chronic vomiting, in areas where canine heartworm disease is endemic. Many cats, once diagnosed and with appropriate supportive care and monitoring, will resolve their infection and be free of clinical signs. 相似文献

Histopathologic, immunopathologic and clinical evaluation of two hundred thirty dogs resulted in a diagnosis of canine autoimmune skin disease (AISD) in eighty four of the suspected cases. Pemphigus foliaceus was the most common diagnosis, followed by bullous pemphigoid and pemphigus vulgaris. The highest percentage of cases were mixed breeds, followed by shelties, collies, German shepherds and poodles. There was no apparent age or sex predilection. Eighty seven percent of the eighty four cases of AISD were diagnosed on the basis of supportive clinical criteria in addition to compatible histopathologic and/or direct immunofluorescent findings. Thirteen percent of the cases with a final clinical diagnosis of AISD lacked supportive immunohistopathologic criteria on biopsy and the diagnosis was based upon clinical appearance, exclusion of other dermatoses, and response to immunosuppressive therapy. This latter group included four cases of SLE diagnosed using a combination of clinical criteria and a positive test for antinuclear antibody. Thirty three percent of the AISD cases were diagnosed on the basis of compatible findings on histopathology direct immunofluorescence. A histopathologic diagnosis of AISD was made in sixty nine percent of the cases. Positive direct immunofluorescence was found in fifty two percent of the cases. Thirty five percent of the AISD cases were diagnosed on histopathologic criteria supportive immunofluorescent findings, while nineteen percent had positive direct immunofluorescence with nonspecific histopathologic changes. The number of definitive positive results was greater for direct immunofluorescence (38%) than for histopathology (25%). There was an equal incidence (21%) of false positive results among non-AISD cases with both tests. Indirect immunofluorescence appears to have little value in the diagnosis of canine AISD. The recommended diagnostic approach to canine AISD involves the use of histopathologic immunopathologic evaluations. 相似文献

Over the last decade, both the farriery and veterinary professions have greatly increased their collective experience and understanding of the treatment of acute laminitis. Many horses that would have not been considered candidates for treatment 10 to 15 years ago are now saved, and some progress to successful careers as athletes. Unfortunately, the difficulties over prediction of the course of the disease persist, which continues to complicate treatment decisions. By its nature, supportive therapy is designed to make the horse more comfortable and limit further laminar injury by countering adverse biomechanical forces. Therefore, the success of treatment depends on the degree of instability between the distal phalanx and the hoof when treatment is started as well as the effectiveness of medical and supportive therapy. 相似文献

This report summarises clinical and pathological observations on Fell pony foals with a range of signs that included ill thrift, anaemia, respiratory infection, glossal hyperkeratosis and diarrhoea. Some of the foals had normochromic, normocytic anaemia and some had low levels of plasma proteins, including immunoglobulin G. Antibiotic and supportive treatment was ineffective and all affected foals died or were killed on humane grounds. Postmortem examination of 12 foals and tissues from 2 other foals revealed a range of lesions that included glossal hyperkeratosis, typhlocolitis, intestinal cryptosporidiosis, granulomatous enteritis, proliferative and necrotising bronchiolitis consistent with adenovirus infection; lesions similar to those in the respiratory tract were present in the salivary gland and pancreas of individual foals. Lymphoid tissue was judged to be smaller than expected. These observations suggest the possibility of opportunistic infections secondary to some form of undefined immunocompromised state. 相似文献

Objective: To describe the clinical consequences following ingestion by a dog of a moxidectin‐containing equine deworming product. Few reports exist concerning the treatment and outcome of severe moxidectin toxicity. Treatment, known factors influencing intoxication, and prognosis are reviewed. Case summary: A 10‐month‐old female Border Collie ingested an unknown quantity of a moxidectin‐containing equine deworming product several hours before presentation. Severe neurological signs subsequently developed and included: ataxia, seizures, coma, and respiratory failure. The dog was treated with supportive care including intravenous fluids, activated charcoal, and positive pressure ventilation. Normal spontaneous respiration returned in 34 hours and the patient was discharged 58 hours after ingestion. Full recovery occurred within 1 week of intoxication. New information provided: This report describes moxidectin intoxication and associated respiratory failure in a dog that required mechanical ventilation. The dog's recovery was rapid. Despite severity of signs, the prognosis for patients with moxidectin intoxication is good with appropriate supportive care. 相似文献
