Three cases of immune-mediated adnexal skin disease treated with cyclosporin     

Noli C  Toma S 《Veterinary dermatology》2006,17(1):85-92

Cyclosporin is currently considered a new and interesting drug in veterinary dermatology for the treatment of immune-mediated skin diseases, and a safe and effective alternative to immunosuppressive therapy with glucocorticoids. The authors report a case of granulomatous folliculitis and furunculosis and of sebaceous adenitis in two cats and a case of alopecia areata in a dog, successfully controlled with cyclosporin.  相似文献   

Echocardiographic and Doppler echocardiographic findings in 11 wolves (Canis lupus)     

Guglielmini C  Rocconi F  Brugnola L  Valerio F  Mattei L  Boari A 《The Veterinary record》2006,158(4):125-129

Two-dimensional real-time, M-mode and Doppler echocardiographic measurements were made in 11 adult wolves (Canis lupus) anaesthetised with an intramuscular combination of medetomidine, ketamine, butorphanol and acepromazine followed by isoflurane in oxygen. M-mode measurements of the left ventricle, B-mode measurements of the left atrium and aorta, systolic indices, and Doppler measurements of aortic and pulmonary blood outflow, and of mitral and tricuspid blood inflow, were recorded. The values obtained were compared with those reported for dogs of similar bodyweight and body type. The diastolic measurements of the cardiac chambers and walls were similar to those reported for healthy, conscious dogs, but the use of anaesthesia probably resulted in the markedly different systolic cardiac measurements, systolic indices and Doppler blood flow velocities observed in the wolves. Mild mitral regurgitation, probably due to mitral endocardiosis, was observed in one wolf, and trivial functional mitral insufficiency was observed in five others.  相似文献   

Use of capecitabine after renal allograft transplantation in dog erythrocyte antigen-matched dogs     

Schmiedt C  Penzo C  Schwab M  Dubielzig R  McAnulty J 《Veterinary surgery : VS》2006,35(2):113-124

OBJECTIVES: To investigate the use of a capecitabine (CAP)-based regimen after renal transplantation in dogs. STUDY DESIGN: Prospective, pilot study. ANIMALS: Healthy, unrelated, dog erythrocyte antigen (DEA)-matched, adult beagles. METHOD: Standard heterotopic renal transplantation with native nephrectomy was performed in 7 dogs. Dogs received oral, twice daily, CAP (250 mg/m2), cyclosporine-A (CsA) (4 mg/kg), ketoconazole (5 mg/kg), and prednisolone (0.25 mg/kg). After 90 days the surviving dogs were euthanatized and complete necropsy was performed. RESULTS: Seven transplants were performed. All dogs survived surgery. Six dogs had acute neurotoxicity, which resulted in death or euthanasia of 2 dogs within 2 days of surgery. In the remaining dogs, toxicity resolved rapidly with cessation of drug administration. Thereafter, modification of the regimen minimized toxicity. The 5 remaining dogs survived to study end; 4 dogs had no evidence of graft rejection. Necropsy examination was mostly unremarkable in all dogs. There were no major changes in CBC or biochemical values, except for a significant increase in serum calcium. CONCLUSIONS: CAP appeared well tolerated in most dogs. Toxicity occurred but abated with modification of the drug regimen. Efficacy for postoperative immunosuppression cannot be determined by this study, although results are promising. CLINICAL RELEVANCE: CAP-CsA-prednisolone is an effective, oral immunosuppressive regimen for prevention of acute allograft rejection in DEA-matched beagles. Further studies on dose, toxicity, and efficacy compared with current immunosuppressive regimens are needed before use in clinical practice.  相似文献   

Comparison of 4 fixation and staining methods for the cytologic evaluation of ear canals with clinical evidence of ceruminous otitis externa     

Toma S  Cornegliani L  Persico P  Noli C 《Veterinary clinical pathology / American Society for Veterinary Clinical Pathology》2006,35(2):194-198

BACKGROUND: Swab cytology of ear canals is one of the most useful and rapid methods to assess the presence of external ear infections. Smears are generally stained with rapid Romanowsky-type stains, with or without prior heat fixation. OBJECTIVES: The aim of this study was to compare 4 different methods of fixation and staining of ear swab cytology samples from dogs. METHODS: Eight dogs with otitis externa were selected from a dermatology referral population. A cotton swab was used to obtain ceruminous material from 12 ear canals. Four smears of each swab were prepared on glass slides (randomly identified as A, B, C, or D) and air-dried for cytologic examination. Samples marked A were stained with Dip Quick (Jorgensen Laboratories Inc, Loveland, CO, USA) after heat fixation; samples marked B were stained without heat fixation; samples marked C were heat-fixed and dipped only in the counterstain (the blue reagent) of Dip Quick; and samples marked D were dipped only in the counterstain, without heat fixation. Ten high-power fields (hpf; X100 oil immersion objective) in each slide were evaluated by 2 observers, and total numbers of keratinocytes, yeast, bacteria, and neutrophils were counted. Statistical comparison was performed using an ANOVA model applied after verifying the normal distribution of the data, and using nonparametric sign tests and Wilcoxon signed rank tests. RESULTS: No statistically significant differences were observed in the numbers of keratinocytes, yeast, bacteria, or neutrophils among the 4 staining methods (P > .05), although significant interobserver differences were found. CONCLUSION: We conclude that heat fixation does not improve the quality of ceruminous ear swab samples for cytologic evaluation, and propose a 1-step dip in the blue reagent alone as a rapid method of staining samples from canine ear canals.  相似文献   

Perception of dogs’ stress by their owners     

Chiara Mariti  Angelo Gazzano  Jane Lansdown Moore  Paolo Baragli  Laura Chelli  Claudio Sighieri 《Journal of Veterinary Behavior: Clinical Applications and Research》2012,7(4):213-219

Questionnaires potentially have a broad applicability in measuring stress levels in dogs, as owners know their dogs’ behavior and personality better than anyone else. The aim of this research was to evaluate how owners perceive stress in their dogs through understanding of displayed behaviors.The survey was carried out using 1,190 questionnaires completed by dog owners. More than half of respondents were able to correctly identify stress as a short- or long-term alteration of the psychophysical equilibrium that can develop into illness. This ability was higher with higher educational levels. The behavioral indicators of stress most frequently identified by owners were trembling and whining, followed by aggressiveness, excessive barking, and panting. More subtle behaviors such as looking elsewhere, turning head, yawning, and nose licking were more rarely reported, suggesting that few owners are able to correctly interpret and intervene in early stages of stress. The vast majority of respondents indicated that dogs were stressed seldom or only in specific situations. Men generally considered their dogs as experiencing low stress more often than did women, whereas women considered their dogs as being moderately stressed more often than did men.An owner’s ability to recognize behavioral signs of stress is important, as it enables the owner to help the animal to avoid welfare problems, such as stressful situations, and favors a rapid recovery of psychophysical homeostasis by interrupting the progression to overstress and distress. The results show that some owners can help in protecting the welfare of their dogs, but that many owners would benefit from educational efforts to improve their ability to interpret their dogs’ behavior.  相似文献   

In vitro digestion assay for determination of hidden fumonisins in maize     

Dall'Asta C  Falavigna C  Galaverna G  Dossena A  Marchelli R 《Journal of agricultural and food chemistry》2010,58(22):12042-12047

Hidden fumonisins have received great attention in the last years as they have been frequently found in maize products in addition to the free forms. Several papers have shown that interaction with macromolecular components such as protein and starch is at the base of the phenomenon: although the nature of the interaction (covalent or not) is still not clarified, the occurrence of hidden forms is generally revealed by the application of an alkaline hydrolysis procedure. In this study, an in vitro digestion model has been applied to raw maize to evaluate the possible release of hidden fumonisins under gastrointestinal conditions. Upon digestion of the food matrix, an increased amount of total detectable fumonisins was observed in comparison with the analysis on the nondigested matrix, an amount even higher than that calculated through the application of the hydrolysis procedure. Besides the analytical issues, our data have serious implications, since consumers may be exposed to a systematic higher risk than that estimated by conventional techniques.  相似文献   

Amniotic membrane transplantation for the treatment of feline corneal sequestrum: pilot study     

Laura Barachetti  Chiara Giudice  Carlo M. Mortellaro 《Veterinary ophthalmology》2010,13(5):326-330

Objectives To describe and evaluate the use of equine amniotic membrane trans‐plantation after lamellar keratectomy for the treatment of corneal sequestrum in cats. Methods Six cats (seven eyes) of various breed and ages with corneal sequestra were treated surgically with lamellar keratectomy and amniotic membrane transplantation. All the sequestra and a small piece of the amniotic membranes used for each surgery were submitted for histopathologic examination. Results Five of the seven eyes showed minimal level of scarring in the cornea and good transparency. No recurrences of the sequestra have been noted during the follow‐up period (3–9 months). One eye had necrosis of the amniotic membrane 2 weeks after the surgery. The sequestrum of this eye showed a high level of bacterial contamination on histopathology. Three months later the same cat developed a descemetocele in the area where the necrotic amniotic membrane was rejected. A second eye developed a perforation under the amniotic membrane two weeks after the surgery. The sequestrum of this eye was deep and without vascularization. Conclusion Amniotic membrane transplantation after lamellar keratectomy was a valid procedure for surgical treatment of corneal sequestrum in cats. The procedure resulted in excellent cosmesis and functional vision in five of seven eyes; although case selection is important, particularly to exclude the very deep and non‐vascularized sequestra.  相似文献   

Treatment of canine Old World visceral leishmaniasis: a systematic review   总被引：1，自引：1，他引：0  

Noli C  Auxilia ST 《Veterinary dermatology》2005,16(4):213-232

Canine visceral leishmaniasis is a systemic disease caused by Leishmania infantum. The aim of this systematic review was to identify and evaluate the evidence of efficacy of interventions for treatment or prevention of canine visceral leishmaniasis, and to propose recommendations for or against their use. Forty-seven articles describing clinical trials published between 1980 and 2004 fulfilled selection criteria. The evaluation of clinical trials provided good evidence for recommending the use of meglumine antimoniate at a minimum dosage of 100 mg kg(-1) daily for at least 3-4 weeks, combined with allopurinol in order to obtain a good clinical efficacy and a reduced relapse rate. The evaluation of the articles also provided fair evidence for recommending the use of pentamidine (4 mg kg(-1) twice weekly) and aminosidine (5 mg kg(-1) twice daily) for 3-4 weeks. There was insufficient evidence for recommending the use of allopurinol alone, amphotericin B, buparvaquone, ketoconazole, enrofloxacin, and the combinations of metronidazole with spiramicyn or metronidazole with enrofloxacin. Fair evidence against the use of aminosidine at high dosages (20-80 mg kg(-1) per day) was proposed due to its side effects. Evaluation of articles on repellent measures against sand fly vectors of leishmaniasis provided good evidence for recommending deltamethrin collars and fair evidence for recommending spot-on permethrin.  相似文献

Thirty 6-trifluoromethylpyrazolo[3,4-d]pyrimidines were synthesised and tested for antifungal activity in vitro against ten phytopathogenic fungi of different taxonomic classes. Six of the compounds had noteworthy activity against Sclerotinia minor, Corticium solani and Phoma betae. The relationships between structure and activity are discussed on the basis of the present and previous studies.  相似文献   

Evaluation of bilateral maxillary nerve block in dogs undergoing surgery for brachycephalic obstructive airway syndrome     

Chiara De Gennaro  Enzo Vettorato  Federico Corletto 《The Canadian veterinary journal. La revue veterinaire canadienne》2022,63(1):67

This retrospective study assessed the effect of an intraoral bilateral maxillary nerve block in dogs undergoing surgery for brachycephalic obstructive airway syndrome (BOAS). Records of dogs that underwent BOAS surgery were retrieved. Cases were assigned to Group B or C if a preoperative bilateral maxillary nerve block was performed or not. Type and dose of local anesthetic, inhalant anesthetic minimum alveolar concentration multiples, intraoperative fentanyl and injectable anesthetic use, prevalence of intraoperative hypotension or bradycardia, and postoperative opioids administration, were compared between groups. Sixty-seven cases met the inclusion criteria: 33 were assigned to Group B and 34 to Group C. In Group C, 18 dogs required intraoperative fentanyl (P = 0.005), and 12 needed injectable anesthetic top-ups (P = 0.006). Hypotension, or bradycardia, were not different between groups. Bilateral maxillary nerve block reduces intraoperative fentanyl and injectable anesthetic requirement in dogs undergoing BOAS surgery.  相似文献
