Cyclosporine A and ketoconazole were used as a combined therapy to treat 19 dogs with anal furunculosis. Complete resolution of all lesions was achieved in three to 10 weeks, but recurrences occurred in seven of the 19 dogs (36.8 per cent), with remission periods extending from one to six months for these dogs. Adverse effects of treatment included excessive hair loss, intermittent lethargy, vomiting and decreased appetite in some dogs, but none of the signs were considered serious. The results of treatment are comparable with, if not better than, the surgical alternatives. There is an approximate 70 per cent cost saving over the use of cyclosporine alone. 相似文献

Treatment of anal furunculosis in dogs is often unsatisfactory and may be associated with significant recurrence and complications. This may be compounded by the simultaneous presence of colitis in affected animals. Clinical signs associated with colitis and anal furunculosis may be similar, including faecal tenesmus, dyschezia and haematochezia. To examine the incidence of concurrent anal furunculosis and colitis, colonic biopsies were collected from 18 dogs referred for treatment of anal furunculosis. Nine dogs (50 per cent) had a histopathological diagnosis of colitis. Clinical signs more indicative of colitis than anal furunculosis (increased frequency of defecation, mucus in faeces and diarrhoea) were not observed more frequently in dogs with confirmed colitis compared with those with furunculosis alone. Therefore, while an association between colitis and anal furunculosis may exist, clinical signs alone cannot be used as an indicator of the presence of colitis in cases of anal furunculosis. The authors recommend that colonic biopsies should be undertaken in all dogs presented with anal furunculosis. Whether specific treatment of colitis in dogs with histopathological evidence of colitis improves the outcome of treatment for anal furunculosis awaits further study. 相似文献

OBJECTIVES: To evaluate the efficacy of combining preoperative immunosuppressive therapy with surgical excision for treatment of anal furunculosis (AF) in dogs. STUDY DESIGN: Retrospective study. ANIMALS: Dogs (n=25) with stages 1-4 AF. METHODS: Preoperative immunosuppressive therapy was either cyclosporine A (CyA) alone or in combination with ketoconazole (Group 1; n=18), or azathioprine combined with prednisolone (Group 2; n=7). Surgical excision of residual draining tracts, cryptectomy, and anal sacculectomy were performed. Only dogs with postoperative clinical follow-up exceeding 9 months were retained for the study. RESULTS: Both immunosuppressive protocols were effective in reducing progression of AF. Subsequent draining tracts excision, cryptectomy, and anal sacculectomy were bilateral (12 dogs) or unilateral (13 dogs of which 4 had bilateral anal sacculectomy). Postoperative recovery was uneventful, except for 2 dogs that had wound breakdown. Recurrence was not observed in any of the dogs that had bilateral surgical excision and or in 9 dogs that had unilateral excision. CONCLUSION: Preoperative immunosuppressive therapy, combined with bilateral surgical resection of affected tissue consistently, resulted in resolution of AF. Four dogs that had recurrence had unilateral excision despite initial bilateral involvement, suggesting that all diseased tissue should be excised. CLINICAL RELEVANCE: These preliminary results suggest that immunosuppressive therapy before surgical excision for AF yields minimizes recurrence in dogs. 相似文献

Twenty-four dogs with anal furunculosis were treated with cyclosporine once daily for 13 weeks at dosages of 1.5, 3.0, 5.0 or 7.5 mg/kg, and re-examined after six and 12 months. After 13 weeks the disease in six of the dogs was in remission, 11 were controlled or improved and seven had failed to respond. The response of the dogs given the highest dose was significantly better than the response of the other groups taken together (P < 0.014), and better than the responses of the groups given 1.5 mg/kg and 5 mg/kg (P < 0.05). The dogs improved clinically during the treatment, most rapidly during the first five weeks. Of the six dogs that were in remission after 13 weeks, three relapsed after one, two and six months. The 11 dogs that were improved or controlled after 13 weeks were either left untreated or were continued on cyclosporine medication for one to three months at a dosage of 1.5 to 7.5 mg/kg; the disease went into remission in four cases and remained controlled in the other seven, but four of the 11 cases relapsed during the 12 months following the treatment. The side effects observed included increased coat turnover and transient vomiting. 相似文献

OBJECTIVE: To evaluate combination therapy with azathioprine and metronidazole in German Shepherd Dogs with perianal fistulae. DESIGN: Prospective study. PROCEDURE: Five dogs (31.5 to 36.0 kg) with perianal fistulae were treated with azathioprine (50 mg per dog orally every 24 h) and metronidazole (400 mg per dog orally every 24 h). Patients were re-evaluated at 2 week intervals by inspection, palpation, photographs of the perineal region and assessment of white blood cell counts where possible. Treatment was continued until improvement in lesions reached a plateau. Surgical excision of residual fistulae and anal sac remnants was then performed, with medical therapy continued for an additional 3 to 6 weeks. RESULT: Signs attributable to anal irritation were reduced or eliminated in all dogs within 2 weeks, although visible healing of lesions progressed more slowly. Ulcerated lesions reduced in surface area and depth, and some fistulae healed completely. Non-healing areas were usually associated with anal sac rupture or chronic fibrosis. Visible improvement typically reached a plateau 4 to 6 weeks after commencing treatment. Immunosuppressive therapy continued for 5 to 24 weeks before surgical intervention to remove anal sacs (four dogs) and/or residual fistulae (five dogs). All dogs remain disease free 7 to 10 months postoperatively. No important complications of treatment were encountered. CONCLUSION: Azathioprine with metronidazole effectively reduced perianal irritation, and the severity and extent of lesions prior to surgery. Treatment was economical even in large dogs and associated with few untoward sequelae. The combined use of immunosuppressive and antimicrobial therapy followed by surgery minimised potential morbidity associated with aggressive use of either medical of surgical treatment alone. 相似文献

Thirty-two cases of canine cutaneous histiocytosis were retrospectively evaluated. Median age at onset was 4 years. Lesions included nodules and plaques affecting the head/face, trunk and limbs, and erythema, swelling and depigmentation of the nasal planum/nares. Systemic involvement was not ruled out in all cases. All dogs had complete resolution of dermatological lesions after initial treatment (median 45 days). Initial treatment included prednisone +/- antibiotics (12 of 32 dogs), prednisone and tetracycline/niacinamide (four of 32), prednisone and azathioprine (three of 32), tetracycline/niacinamide +/- vitamin E/essential fatty acids (six of 32), antibiotics +/- antihistamines (three of 32), cyclosporine and ketoconazole (one of 32), topical therapy (two of 32), and no treatment (one of 32). Seventeen dogs received maintenance therapy which consisted of tetracycline/niacinamide +/- vitamin E/essential fatty acids (12 of 17), cyclosporine/ketoconazole (two to three times a week) (two of 17), azathioprine daily (one of 17), prednisone/azathioprine (two times a week) (one of 17), and prednisone daily (one of 17). Median follow up was 25 months. Nine dogs had a recurrence of cutaneous histiocytosis (median days to recurrence 130 days), with seven of nine having more than one recurrence. At study completion, six dogs were deceased (no lesions at the time of death) and 26 of 32 were alive with no lesions. Ten of 26 dogs were on maintenance treatment (eight tetracycline/niacinamide, one azathioprine, one vitamin E). Previous dermatological disease and season had no detectable influence on recurrence. Recurrence was significantly more likely in dogs with nasal planum/nares lesions than dogs without these lesions. Tetracycline/niacinamide was an effective treatment option for dogs in this study population. 相似文献

OBJECTIVES: To describe clinical features of brachycephalic airway obstructive disease in dogs, the incidence of laryngeal collapse in dogs presenting for surgery and the outcome after surgery in dogs with laryngeal collapse. METHODS: Basic clinical details were reviewed retrospectively in 73 dogs. Presence of laryngeal collapse and short-term outcomes after surgery were determined for 64 dogs with complete medical records. Long-term outcomes were reviewed for 46 dogs by telephone survey between 19 and 77 months following surgery. RESULTS: Stenotic nares were present in 31 dogs (42.5 per cent), elongated soft palate in 63 (86.3 per cent) and everted laryngeal saccules in 43 (58.9 per cent). The most common breeds were the pug (19 dogs, 26 per cent), Cavalier King Charles spaniel (15 dogs, 20.5 per cent), British bulldog (14 dogs, 19.2 per cent) and Staffordshire bull terrier (4 dogs, 5.5 per cent). Laryngeal collapse was present in 34 of 64 (53 per cent) dogs. No dogs died perioperatively and only one dog was euthanased as a result of its respiratory disease three years after surgery. Telephone interviews indicated that 26 dogs (56.5 per cent) were much improved after surgery, 15 (32.6 per cent) had some improvement and 5 (10.9 per cent) showed no improvement. Signs that persisted after surgery were snoring during sleep (34 dogs, 73.9 per cent), stertor/stridor while conscious (23 dogs, 50 per cent), excessive panting (13 dogs, 28.3 per cent) and dyspnoea (10 dogs, 21.7 per cent). Long-term outcome was considered good, even in dogs with laryngeal collapse. CLINICAL SIGNIFICANCE: Laryngeal collapse is relatively common in dogs presented for surgical correction of brachycephalic airway obstructive disease. Dogs with severe laryngeal collapse often respond well to surgery. Clinical signs rarely resolve completely following surgery. 相似文献

Cyclosporin was used, as the sole agent, to treat six cases of anal furunculosis, allowing the clinical response to the drug to be evaluated. The initial dose was 7.5 mg/kg twice a day. Following one week of treatment, whole blood cyclosporin trough levels were measured and the dose was adjusted to obtain a stable trough level of 400 to 600 ng/ml. In all dogs, the lesions were found to follow a similar pattern of resolution throughout the course of treatment. The presenting signs disappeared within one week of treatment, with a reduction in lesion size of 50 to 90 per cent. Lesions then gradually healed over the remainder of the treatment, which lasted from 10 to 20 weeks. One case required cryosurgical treatment to resolve a 2 mm diameter persistent ulcerated lesion following 18 weeks of treatment. The length of follow-up was four to 14 months (mean 7.7 months). One case developed recurrence of the lesions eight weeks post-treatment. 相似文献

Canine generalized demodicosis (CGD) is a skin disease with distinct breed predispositions. Secondary bacterial infections are common. Dogs typically receive miticidal therapy in combination with antibacterial treatment. Whether antibiotics influence the duration of acaricidal therapy is unknown at the moment. There is also debate over how common short-tailed Demodex mites occur in demodicosis. This study evaluated the influence of systemic antibiotics on the course of CGD, the occurrence of short-tailed Demodex mites in demodectic dogs and the influence of furunculosis on treatment outcome. Breed predispositions for CGD in Moscow were identified. Fifty-eight dogs were randomly distributed in two groups. Both were treated with ivermectin 600 mcg/kg q24h orally and benzoyl peroxide shampoo weekly. The dogs in one group (AB) were additionally treated with systemic antibiotics for at least 1 month, dogs in the other group (NAB) were not. Monthly examinations, skin scrapings and impression smears were performed. Prior to the study there was no difference in clinical severity, presence of pyoderma and mite numbers between groups. There was no significant difference in duration until first negative skin scrapings and resolution of bacterial infection. In dogs with furunculosis the number of the mites was significantly higher than in dogs without furunculosis but the duration until microscopic remission albeit longer, was not significantly different. Short-tailed Demodex mites were found in 25% of the cases. Pugs and English Bulldogs were predisposed. Based on these results, systemic antibiotics may not impact as much as previously thought on the actual success of CGD treatment. 相似文献

Objectives : To evaluate frame constructs, postoperative fracture reduction, postoperative care, complications, treatment duration and outcome of circular external fixation for management of 49 antebrachial and crural fractures in dogs. Methods : Medical records of dogs that underwent surgery with circular external fixation were examined for fracture location, frame configuration, postoperative fracture reduction, treatment duration, complications and outcome. Results : Forty‐nine fractures in 48 dogs were stabilised using circular external fixation. Frame removal occurred on average 61 days after surgery (median±sd, 52±30 days). Minor complications were observed in 35 cases (71 per cent) and major complications in seven (14 per cent). Radiographic outcome at frame removal was judged as excellent in 18 cases (37 per cent), as good in 26 (53 per cent), as fair in four (8 per cent) and poor in one (2 per cent). After frame removal, one fracture was stabilised with a plate, and eight patients were lost to follow‐up. Functional and cosmetic outcome at follow‐up was judged as excellent in 32 cases (80 per cent), good in seven (18 per cent) and fair in one (2 per cent). Clinical Significance : Circular external fixation can effectively treat antebrachial and crural fractures in dogs, even geometrically complex fractures. Minor complications are frequent but easily managed in most instances. Healing time is comparable to that of other external fixation methods. 相似文献

AIMS: To retrospectively evaluate the outcome of surgical management of anal furunculosis (AF) in 51 dogs. To compare the outcome of surgery with those of current medical protocols by way of a review of the literature. METHODS: Dogs referred for treatment of AF (n=51) were treated by en bloc surgical resection of diseased tissue and primary wound closure. This technique was combined with bilateral anal sacculectomy in all cases in which the anal sacs had not been previously removed. Immunomodulatory therapies were not used, with the exception of post-operative metronidazole antibiosis for 7-10 days. Follow-up was performed by the author using a telephone questionnaire. RESULTS: Forty-eight dogs were eligible for post-operative follow-up 1.5 to 36 (mean 17.4, median 18) months after surgery. Lesion recurrence, faecal incontinence and stricture formation occurred in 2%, 4% and 13% of dogs, respectively. The percentage of dogs considered by their owners to have an acceptable level of faecal continence and an improved quality of life was 94%. CONCLUSIONS AND CLINICAL RELEVANCE: The aetiopathogenesis of canine AF remains unclear. Whilst recent advances in medical management by the use of various immunomodulatory medications (such as cyclosporine) hold promise, this approach has yet to be refined with respect to affordability, long-term efficacy and morbidity. With meticulous surgical dissection and reconstruction techniques (anoplasty), excellent success rates can be achieved following a single surgical procedure with minimal complications. Surgery remains a viable treatment option, alone or in combination with immunomodulatory medications, until a more thorough understanding of this debilitating disease is achieved. 相似文献

OBJECTIVES: To evaluate the effect of short duration 1 per cent clotrimazole flush when combined with 1 per cent clotrimazole cream instilled into the frontal sinuses for the treatment of nasal aspergillosis in 14 dogs. METHODS: Fourteen dogs with clinical, radiological, serological and rhinoscopic findings consistent with nasal aspergillosis were treated by frontal sinus trephination and a short, five-minute flushing of 1 per cent topical clotrimazole solution followed by a 1 per cent clotrimazole cream instilled as a depot agent. RESULTS: Twelve of the 14 dogs (86 per cent) responded well to treatment and either had no clinical signs after treatment or had signs consistent with mild rhinitis during a minimum follow-up period of six months. Only one dog required multiple treatments. Treatment was well tolerated by all patients, with minimal complications. CLINICAL SIGNIFICANCE: This treatment compares favourably to previously published data using one-hour topical clotrimazole or enilconazole flushing treatment protocols. The treatment technique significantly reduced treatment time under anaesthesia. 相似文献

OBJECTIVE: To investigate the effect of cyclosporine (2 or 5 mg/kg every 24 hours) on perianal fistulae (PAF) lesions. STUDY DESIGN: Blinded randomized, prospective trial. ANIMALS: Dogs (n = 20) with perianal fistulae. METHODS: Dogs were randomly assigned to administration of either 2 mg/kg (n = 10) or 5 mg/kg (n=10) of cyclosporine orally every 24 hours for 8 weeks. Lesion surface area was measured, lesion severity was graded using a visual analog scale, and the presence and severity of clinical signs recorded every 2 weeks. RESULTS: Lesion variables were significantly reduced in both groups after 8 weeks and owners also reported a reduction in clinical sign severity. The 5 mg/kg dose rate significantly accelerated lesion resolution compared with 2 mg/kg. In the 2 mg/kg group, 20% of dogs had complete resolution of clinical signs and 10% had resolution of lesions. In the 5 mg/kg group, 40% of dogs had complete resolution of clinical signs and 60% had resolution of lesions. CONCLUSIONS: A dose rate of 5 mg/kg every 24 hours was more effective at reducing the surface area and severity of PAF lesions than 2 mg/kg every 24 hours but less effective at resolving PAF lesions than previous studies using dose rates > or =5 mg/kg every 12 hours. CLINICAL RELEVANCE: Cyclosporine at 5 mg/kg every 24 hours may be useful for the palliation of PAF lesions. 相似文献

The case records of 98 dogs with a left-to-right shunting patent ductus arteriosus (PDA) were reviewed. There were 35 breeds represented, with a female to male ratio of 3:1. Forty per cent of the dogs were older than one year at initial presentation and 31 per cent had clinical signs attributable to PDA. A left heart base continuous murmur of grade IV/VI or higher was noted in 90 per cent of the dogs. On electrocardiography, the most common abnormalities were tall R waves (63 per cent) and deep QII waves (62 per cent). The radiographic triad of dilation of the descending aorta with enlargement of the main pulmonary artery segment and left atrium, typical of PDA, was noted in only 26 per cent of cases. Two-dimensional (2D) and M-mode echocardiography detected left atrial enlargement (35 per cent) and an increased left ventricular diameter in diastole (82 per cent) and systole (84 per cent) as the most common abnormalities. Doppler echocardiography demonstrated increased aortic outflow velocities in 66 per cent of cases. The overall short-term successful outcome in this study was 95 per cent. There was no significant difference between surgical ductal ligation using a standard technique or the Jackson-Henderson technique in terms of survival, occurrence of haemorrhage or residual shunting. The number of interventional procedures used in this study was too low for statistical comparison, but there appeared to be a trend towards a higher rate of residual shunting and a lower fatality rate using a coil occlusion technique. 相似文献

This prospective study aimed to record the toxicity profile of a dose-intensifying simultaneous chemotherapy (DISC) protocol for lymphoma in dogs. Remission rates and the duration of the protocol were also evaluated. Twenty-one dogs were studied. Diagnosis was based on cytological or histological assessments. The DISC protocol is a 13-week maintenance-free protocol. L-Asparaginase (400 iu/kg) was administered subcutaneously on day 1, followed by weekly simultaneous intravenous administration of vincristine (0.7 mg/m(2) = 100 per cent), cyclophosphamide (200 mg/m(2) = 100 per cent) and doxorubicin (30 mg/m(2) = 100 per cent) at a starting dose level of 33 per cent. Dose levels were given twice and then increased by 5 to 7 per cent if grade 0 or I toxicities were seen, to a maximum dose level of 60 per cent. Two dogs experienced a grade IV toxicity (asymptomatic neutropenia in one dog and sepsis in the other). Two episodes of asymptomatic grade III thrombocytopenia and one episode of neutropenia were recorded. Other toxic events were infrequent and mild. Only one dog required hospitalisation for less than 72 hours. Seventeen dogs (80.9 per cent) achieved complete remission, one (4.8 per cent) achieved partial remission, two (9.5 per cent) had stable disease and in one (4.8 per cent) disease progressed. 相似文献

Aim Topical cyclosporine has been widely used in the treatment of canine keratoconjunctivitis sicca without apparent documented clinical side effects. Thus the finding of reduced lymphocyte proliferation in animals treated with the drug at a concentration of 2% was both surprising and concerning. This study aimed to repeat the previous study and to compare the systemic effects of 2% cyclosporine in corn oil and 0.2% topical cyclosporine ointment (Optimmune, Intervet‐Schering Plough, Welwyn, UK). Methods Twenty dogs treated with Optimmune or with topical 2% cyclosporine in corn oil where previous treatment with Optimmune had failed were included in this study. Blood samples were taken at the time of first evaluation and at 1, 3 and 6 months of treatment to provide a biochemical and hematological health evaluation of the dogs and at each examination to measure circulating levels of cyclosporine and to obtain a lymphocyte population with which to determine a mitogen stimulation index (MSI) on treatment with phytohaemagglutinin‐P (PHA) and conconavlin A (con‐A). Levels of circulating cyclosporine were measured with an enzyme‐multiplied immunoassay method and also the more sensitive quantification technique of mass spectroscopy (MS). Results No blood samples contained over 15 ng/ml cyclosporine, the lower limit of detection using the radioimmunoassay or the enzyme‐multiplied immunoassay technique. Positive control samples taken from dogs treated with oral cyclosporine for anal furunculosis showed measurable levels in blood, demonstrating that the technique worked. Mean MSI values at 0, 1, 3 and 6 months of treatment were 10.2, 11.4, 11.6, and 10.5 for dogs treated with 0.2% cyclosporine and 10.4, 11.9, 11.7, and 12.9 for dogs treated with 2% cyclosporine. Mitogen stimulation index values were not statistically different between the first examination and any subsequent examination time‐point. Conclusions The findings of the study contradict those of the previous studies. No change in lymphocyte stimulation index was noted, neither were significant blood levels of cyclosporine documented after topical administration of either 0.2% or 2% cyclosporine. This study shows that topical cyclosporine is safe to use in the canine eye in line with the drug’s safety record in this therapeutic regime over the past 20 years since its first use. 相似文献

Perianal tissue obtained from 10 normal dogs and 40 dogs with anal furunculosis was immunostained in order to determine the number and distribution of B lymphocytes/plasma cells (expressing IgG, IgM or IgA) and T lymphocytes (expressing the CD3 marker) within the inflammatory infiltrates. Differences in these parameters between tissue obtained from affected German shepherd dogs (n = 20) and affected dogs of other breeds (n = 20) were recorded. The immunological phenotype of cells comprising lymphoid follicles and associated with ductal eosinophilic pustules observed in the anal sacs of dogs with anal furunculosis is described. The results of this study suggest that a simple immunological defect does not underlie the predisposition of dogs of the German shepherd breed for anal furunculosis. 相似文献

An 11-year-old, neutered male German shepherd dog was presented with perianal ulceration and fistulas. A clinical diagnosis of anal furunculosis was made, and the dog was treated with cyclosporine and ketoconazole. The perianal lesions resolved. However, after four weeks of therapy the dog developed multicentric lymphoma. Complete remission was achieved with combination chemotherapy (Wisconsin-Madison protocol). Cyclosporine administration is associated with an increased risk of development of lymphoma in humans and a similar increased risk might be expected in dogs. Although a causative relationship between cyclosporine administration and the development of lymphoma cannot be proven in this case, it is possible that cyclosporine therapy may have contributed to lymphomagenesis. As the use of cyclosporine in small animals is increasing, further work is required to substantiate and quantify the proposed increased risk. 相似文献

The potential value of the pinnal-pedal scratch reflex as an aid to diagnosing canine scabies was assessed in 588 dogs with skin disease. The reflex was assessed by vigorously rubbing the tip of one earflap on to the base of the ear for five seconds, and it was considered positive if the ipsilateral hind leg made a scratching movement. A diagnosis of scabies was based on the dog's history, a physical examination and either positive skin scrapings or the complete resolution of pruritus and dermatitis after treatment with ivermectin or milbemycin, with no relapse for at least 12 months. Scabies was diagnosed in 55 of the dogs, allergic skin disease in 463, and 70 had other miscellaneous skin diseases. There was a positive pinnal-pedal scratch reflex in 45 (82 per cent) of the 55 dogs with scabies. Forty (73 per cent) of the dogs with scabies had pinnal dermatitis, and 36 (90 per cent) of these had a positive pinnal-pedal scratch reflex. There was a positive pinnal-pedal scratch reflex in 33 (6.2 per cent) of the other 533 dogs. On the basis of these results, the specificity of testing for scabies by the pinnal-pedal scratch reflex was 93.8 per cent, and the sensitivity was 81.8 per cent The test's positive predictive value was 0.57 and its negative predictive value was 0.98. 相似文献
