Extreme eosinophilia with disseminated eosinophilic granulomatous disease is described in a 4-year-old Arabian mare. Clinical signs included weight loss, coughing, jugular distention, and ventral edema. Cutaneous lesions were not observed. Eosinophilic inflammation was observed in cytologic specimens from the respiratory tract, body cavities, and lymph nodes. At necropsy, a 20-cm diameter intrathoracic mass was observed. Smaller nodules were present in the lymph nodes, liver, spleen, adrenal glands, pancreas, and skeletal muscle. Histologically, these masses and nodules were characterized by infiltrates of eosinophils, macrophages, and multinucleated giant cells, reactive fibroplasia; and multifocal eosinophilic coagula. Microscopically, mild eosinophilic infiltrates were observed in sections of stomach, small intestine, colon, and pleura; however, gross lesions were not observed in these tissues at necropsy. The etiology of the extreme eosinophilia and disseminated eosinophilic granulomatous disease in this horse was not determined. 相似文献

The onset of idiopathic thrombocytopenic purpura (ITP) is related to excessive destruction of platelet resulting from antiplatelet autoantibody. The immunity with ITP is imbalance, so the hypofunction of suppressor T cell (Ts) can't restrain B lymphocytes producing antibody, as a result, autoant ibody is produced, the clearance of platelet in blood circulation is accelerated. The different antibodies have different functions on ITP. The measuring of platelet antibody has its significance in diagnosis, therapeutic evaluat ion and expectation of prognosis. 相似文献

Idiopathic polyarthritis (IPA) is a very common inflammatory arthropathy in the dog.
Canine IPA is diagnosed mainly by detecting increased number of leukocytes in the synovial
fluid (SF), which is easily influenced by glucocorticoid therapy. We obtained 31 SF
samples from 24 IPA dogs prior to (n=19) and/or after
(n=12) 1 to 10 weeks of glucocorticoid therapy. The SF total protein
concentrations of IPA dogs were significantly higher than those of dogs with non-arthritis
diseases (n=34) and healthy controls (n=10). Our data
revealed that the SF total protein concentrations are not influenced by several weeks of
glucocorticoid therapy. Hence, the SF total protein concentration is applicable as a
diagnostic marker of canine IPA even when the patients are receiving glucocorticoid
therapy. 相似文献

Objective To describe the clinical data of dogs with neurogenic Keratoconjunctivitis sicca (KCS) and an ipsilateral dry nose without other neurologic deficits. Procedure The retrospective case study included 11 dogs diagnosed with neurogenic KCS and an ipsilateral dry nose between 2006 and 2010. Medical records were reviewed for breed, age, sex, history, suspected cause of neurogenic KCS, clinical signs, and treatment modalities. Follow‐up information was obtained by re‐examination of patients or completion of a telephone survey with the referring veterinarian or the owners. Results Mean age of the dogs was 6.6 ± 4.5 years. Neurogenic KCS was diagnosed in three females, five spayed females, one male, and two castrated males representing 10 different breeds. Ophthalmic signs of KCS (mean Schirmer tear test [STT] value of 1.9 ± 2.9 mm/min) combined with an ipsilateral dry nose were diagnosed in seven left and four right eyes. The suspected cause of neurogenic KCS was idiopathic in nine and trauma in two cases. Systemic therapy consisted of oral pilocarpine 1–2% eye drops combined with case‐specific topical treatment with cyclosporine 0.2% and tear substitutes. Duration of systemic treatment with pilocarpine until healing was 125 days (range 84–204, median 98 days) for five dogs. One dog was lost to follow‐up, and the remaining five dogs are still under systemic treatment with pilocarpine. Conclusions Neurogenic KCS with an ipsilateral dry nose seems to be a predominantly idiopathic disease of middle‐aged female dogs without breed predisposition, which may be self‐limiting in some cases. 相似文献

Purpose To describe the clinical, histological, and immunohistochemical manifestations of canine necrotizing scleritis. Methods A retrospective examination of the clinical records and samples of ocular tissues from five dogs with a histological diagnosis ‘necrotizing scleritis’ was completed. Archived, formalin‐fixed, paraffin‐embedded samples and two control globes were stained with hematoxylin and eosin, Gram, periodic acid–Schiff (PAS) and Masson trichrome stains, and they were immunohistochemically labeled for CD3, CD18, and CD20. Results Of the five cases reviewed, only two could be confirmed as idiopathic necrotizing scleritis. The other three cases were retrospectively diagnosed as unilateral focal, non‐necrotizing scleritis, one as episcleritis and the third was scleritis secondary to a proptosed globe based on our retrospective clinical, histological, and immunohistochemical evaluations. In these two cases, idiopathic necrotizing scleritis manifested as a bilateral, progressive, inflammatory disease of the sclera and cornea that induces significant uveitis. Light microscopic examination confirmed collagen degeneration and granulomatous inflammation. There was no evidence for an infectious etiology based on Gram’s and PAS stainings. Immunohistochemical labeling revealed a predominance of B cells in idiopathic, bilateral necrotizing scleritis. Tinctorial staining abnormalities with Masson’s trichrome stain were present in scleral collagen of the two cases with idiopathic necrotizing scleritis as well as a case of secondary traumatic scleritis. Conclusions Based on a limited number of cases, idiopathic canine necrotizing scleritis shares similar histopathological features with non‐necrotizing scleritis and episcleritis; however, necrotizing scleritis is B‐cell‐dominated and bilateral, and significant collagen alterations manifest with Masson’s trichrome stain. 相似文献

Summary The latencies of the peaks in brainstem responses and the threshold response were determined in 18 healthy beagles. In the first series of measurements the dogs were sedated and the stimulus was delivered via an in‐the‐ear transducer. The latencies, the threshold levels, and the influence of the stimulus repetition rate on the latencies were measured. Using a miniature electret microphone in the outer ear canal near the tympanic membrane, it was found that at a level setting corresponding to 0 dB human level (HL) the major peak in damped oscillation during condensation reached a sound pressure level (SPL) of about 27 dB and the secondary rarefaction peak reached 24 dB SPL. In the second series of measurements the dogs were not sedated and the stimulus was delivered via a headphone. The wave forms, the mean latencies for peaks I to V as a function of the stimulus level, and the threshold of each wave are presented from both series. In the first series the latency values at 80 dB HL (107 dB SPL) were 1.21, 1.97, 2.67, 3.12 and 3.61 ms for peaks I, II, III, IV and V, respectively. The thresholds for peaks I to V were 47.5 ± 9.5, 47.5 ± 11.5, 41.3 ± 13.0, 63.3 ± 17.4 and 28.0 ± 9.7 dB HL, respectively. The difference in peak latency between the first and the second series was 0.065 ms. This difference corresponded to the difference in length of the acoustic pathways. Analysis of variance was used to determine whether the successive peaks in the response followed at a constant time interval, i.e., whether a shift in the first peak with a change in the stimulus level was followed by the same shift in subsequent peaks. The analysis showed a significant (P < 0.001) interaction between the inter‐peak latency differences and the effect of stimulus level. This inter‐peak latency depended on stimulus level, although the effect was small. The use of the in‐the‐ear transducer and sedation resulted in a far more efficient procedure than the use of the headphone without sedation. 相似文献

A 3-year-old, neutered male Persian cat with chronic ulcerative facial dermatitis was diagnosed with feline idiopathic facial dermatitis based on signalment, clinical history and diagnostic test results, including dermatohistopathological evaluation. Initial treatment started with 4 weeks of oral antifungal/antibiotic medication for severe secondary infectious dermatitis of Malassezia and bacteria. As the lesions gradually improved, the oral medication was withdrawn, leaving only 0.1% topical FK506 (tacrolimus) ointment for the remaining lesions. Topical treatment was administered just in case any new lesions developed. The patient has been managed effectively with topical tacrolimus and no side-effects were observed during treatment. Feline idiopathic facial dermatitis is known as a difficult dermatosis to manage successfully, but our experience suggests that it may respond to topical tacrolimus. 相似文献
