Risk factors for equine laminitis were examined in a prospective case-control study of the 258 cases seen at six collaborating veterinary teaching hospitals over a 32-month period. Case-control pairs were matched on institution, clinician, and season of diagnosis. The 90% of case-control pairs (78 acute, 155 chronic) that had complete data for age, gender, and breed were used in separate conditional logistic-regression models for acute and chronic laminitis. There was an increase in risk for horses with acute laminitis from 5 to 7 years of age (OR 4.7, 95% CI 1.3–16) and from 13 to 31 years of age (OR 3.9, 95% CI 1.3–12) (both compared to <5 years); risk was increased for chronic laminitis from 10 to 14 years (OR 3, 95% CI 1.4–6.8) and from 15 to 38 years (OR 2.9, 95% CI 1.4–6.1) (both compared to <6 years). Mares — but not stallions — were more likely than geldings to develop acute laminitis (OR 2.6, 95% CI 1.1–6.2) and chronic laminitis (OR 2.0, 95% CI 1.1–3.6). In the small acute-laminitis data set, the breed variable was collapsed into three categories: Thoroughbred (THB, reference), the Quarter Horse (QH), and other (non-QH-THB). The non-QH-THB group was at increased risk of acute laminitis (OR 3.8, 95% CI 1.2–11.8). For the seven breed-group categories used in the chronic-laminitis model, however, all non-THB breed groups appeared significantly at risk as compared to the THB, with odds ratios ranging from 3.3 (95% CI 1.3–8.30) for the QH to 9.1 (95% CI 2.1–39.3) for ponies.  相似文献

A case-control study was carried out to determine whether residential exposure to environmental pollutants increased risk for canine lymphoma in pet dogs. One hundred one cases with cytologically or histologically confirmed lymphoma diagnosed at a veterinary teaching hospital between the middle of 1996 and the middle of 1998 were examined. Controls were obtained by choosing twice the number of dogs without neoplastic disease, with overlapping distributions of province of residence, age, sex, and breed. Information regarding animal management, residence type, professional or hobby use of chemicals by owners, and treatment with herbicides or other pesticides in the area frequently visited by the dogs was obtained with a multiple-choice questionnaire by telephone interview. Two variables were positively and independently associated with the disease, namely residency in industrial areas (odds ratio [OR]; = 8.5; 95% confidence interval [CI], 2.3-30.9) and use of chemicals by owners, specifically paints or solvents (OR = 4.6; 95% CI, 1.7-12.6). A significantly lower value of the mean age of disease onset was found in the group of dogs at risk in comparison with the group of all other dogs (6.1 +/- 0.4 years, n = 36 versus 7.5 +/- 0.4 years, n = 65, respectively; P = .008). Variables describing animal care and pesticide use were either not associated with the disease or were uninformative. We suggest that canine lymphoma may be considered a sentinel of potentially hazardous situations for humans, because of the relatively short latency between exposure and disease onset.  相似文献

BACKGROUND: The occurrence of spontaneous tumors in pet animals has been estimated in a few European and North American veterinary cancer registries with dissimilar methodologies and variable reference populations. OBJECTIVES: The Animal Tumor Registry (ATR) of Genoa, Italy, was established in 1985 with the aim of estimating the occurrence of spontaneous tumors in dogs. METHODS: Six thousand seven hundred and forty-three tumor biopsy specimens were received from local veterinarians in the Municipality of Genoa between 1985 and 2002. Three thousand and three hundred and three (48.9%) biopsy specimen samples were diagnosed as cancer and were coded according to the International Statistical Classification of Diseases (ICD-9). RESULTS: Mammary cancer was the most frequently diagnosed cancer in female dogs, accounting for 70% of all cancer cases. Incidence of all cancers was 99.3 per 100,000 dog-years (95% CI: 93.6-105.1) in male dogs and 272.1 (95% CI: 260.7-283.6) in female dogs. The highest incidence rates were detected for mammary cancer (IR = 191.8, 95% CI: 182.2-201.4) and for non-Hodgkin's lymphoma (IR = 22.9, 95% CI: 19.7-26.5) in bitches and for non-Hodgkin's lymphoma (IR = 19.9, 95% CI: 17.4-22.7) and skin cancer (IR = 19.1, 95% CI: 16.6-21.8) in male dogs. All cancer IR increased with age ranging between 23.7 (95% CI: 18.4-30.1) and 763.2 (95% CI: 700.4-830.1) in bitches and between 16.5 (95% CI: 12.8-21.1) and 237.6 (95% CI: 209.1-269.0) in male dogs aged < or =3 years and >9-11 years. CONCLUSION: This study summarizes the work done by the ATR of Genoa, Italy, between 1985 and 2002. All cancer incidence was 3 times higher in female than in male dogs, a difference explained by the high rate of mammary cancer observed in bitches. Because a biopsy specimen was required to make a cancer diagnosis, cancer rates for internal organs cancers, such as respiratory and digestive tract cancers may have been underestimated in the study population.  相似文献

We studied risk factors and characteristics of canine transmissible venereal tumours (TVTs) in Grenada. We abstracted data for 38 TVT cases and 114 TVT-free dogs submitted to a veterinary diagnostic laboratory between 2003 and 2006. Occurrence profiles, odds ratios (ORs), and logistic regression models for TVT were determined using a significance level of α = 0.05. TVT was found in 20 (52.6%) female and 18 (47.4%) male dogs. Of the TVT cases, 32 (84.2%) were between 1 and 7 years old, 20 (52.6%) were mixed breeds of dogs, 14 (36.8%) were Grenadian pothounds, while 4 (10.6%) were pure-bred dogs. Characteristic TVT lesions were genital growths [OR = 96.7; 95% CI (27,461), P < 0.001], genital bleeding [OR = 12.7; 95% CI (4.6, 39.2), P < 0.001] and secondary inflammation of TVT lesion [OR = 4.3; 95% CI (2, 10), P < 0.001]. Extragenital TVT lesions were observed in 23% (9/38) of dogs. An increased risk for TVT was associated with age as adult (1–7 years) dogs [OR = 12; 95% CI (1.6, 94), P < 0.001] and status as a Grenadian pothound [OR = 8.6; 95% CI (3, 25), P < 0.001]. Clinicians should educate dog owners about increased risk of TVT for Grenadian pothounds and consider TVT as a possibility for some extragenital tumours.  相似文献

Background

To date, epidemiological studies on degenerative mitral valve disease (DMVD) in dogs have largely reported referral caseloads or been limited to predisposed breeds. Analysis of primary‐care data to identify factors associated with DMVD would help clinicians identify high‐risk individuals and improve understanding.

Objectives

To estimate the prevalence of and identify risk factors for DMVD in dogs attending primary‐care veterinary practices in England.

Animals

Cases were identified within the electronic patient records of 111,967 dogs attending 93 practices. Four hundred and 5 dogs were diagnosed with DMVD (diagnosed cases) and a further 3,557 dogs had a heart murmur (HM) consistent with DMVD (possible cases).

Methods

Retrospective cross‐sectional study design. Prevalence was adjusted for the sampling approach. Mixed effects logistic regression models identified factors associated with DMVD.

Results

Prevalence estimates of diagnosed DMVD and HMs consistent with DMVD (both diagnosed and possible cases) were 0.36% (95% confidence interval [CI]: 0.29–0.45) and 3.54% (95% CI: 3.26–3.84) respectively. In the multivariable analysis, males had higher odds of diagnosed DMVD than did females (odds ratio [OR] 1.40, 95% CI: 1.12–1.74). Insured dogs had increased odds of DMVD compared with noninsured dogs (OR 3.56, 95% CI: 2.79–4.55) and dogs ≥20 kg had approximately half the odds of DMVD diagnosis compared with dogs <20 kg (OR 0.51, 95% CI: 0.36–0.74). Strong associations between a DMVD diagnosis and individual breeds and age were identified.

Conclusions and Clinical Importance

Degenerative mitral valve disease was a common disorder in practice‐attending dogs. Knowledge of identified risk factors for DMVD could improve clinical diagnosis and direct future research.  相似文献

Veterinarians and veterinary technicians are at risk for occupational brucellosis. We described the risk factors of occupational brucellosis among veterinary personnel in Turkey. A multicenter retrospective survey was performed among veterinary personnel who were actively working in the field. Of 712 veterinary personnel, 84 (11.8%) had occupational brucellosis. The median number of years since graduation was 7 (interquartile ranges [IQR], 4–11) years in the occupational brucellosis group, whereas this number was 9 (IQR, 4–16) years in the non-brucellosis group (p < 0.001). In multivariable analysis, working in the private sector (odds ratio [OR], 2.8; 95% confidence interval [95% CI], 1.55–5.28, p = 0.001), being male (OR, 4.5; 95% CI, 1.05–18.84, p = 0.041), number of performed deliveries (OR, 1.01; 95% CI, 1.002–1.02, p = 0.014), and injury during Brucella vaccine administration (OR, 5.4; 95% CI, 3.16–9.3, p < 0.001) were found to be risk factors for occupational brucellosis. We suggest that all veterinary personnel should be trained on brucellosis and the importance of using personal protective equipment in order to avoid this infection.  相似文献

Infection and colonization with methicillin-resistant Staphylococcus aureus (MRSA) are now increasingly being reported in animals and people who work with animals, including horses and horse personnel. The objectives of this study were to evaluate the prevalence of MRSA colonization in veterinary personnel attending an international equine veterinary conference, and to identify risk factors for MRSA colonization in this group. Volunteers were recruited at the conference to provide a single nasal swab and complete a questionnaire regarding contact with the human health care system, contact with horses, and personal hand hygiene. Colonization with MRSA was found in 26/257 (10.1%) of study participants. Multivariable analysis showed an increased risk of MRSA colonization associated with having been diagnosed with or having treated a patient diagnosed with MRSA colonization or infection in the last year (odds ratio [OR] 8.41, 95% confidence interval [CI] 1.51–49.92, P = 0.015; OR 3.27, 95% CI 1.05–10.11, P = 0.039, respectively), whereas hand washing between infectious cases (OR 0.27, 95% CI 0.11–0.72, P = 0.009) and hand washing between farms (OR 0.35, 95% CI 0.14–0.98, P = 0.047) were protective. The prevalence of MRSA colonization among equine veterinary personnel found in this study was high compared to that of other studies of the general population. These data support previous suggestions that equine veterinary personnel are at increased risk of colonization with MRSA. This is the first study to demonstrate a statistically significant association between hand hygiene practices and a measurable clinical outcome in veterinary medicine.  相似文献

In this study we undertook a comprehensive analysis of a Pet Tumour Registry of the Canary Archipelago (PTR-CA) in Spain to investigate the epidemiology of canine cutaneous round cell tumours. From a database of 2526 tumours collected from 2003 to 2020, we conducted a longitudinal analysis of the main trends in diagnosis, age, multiplicity and anatomical distribution as well as a case–control study comparing these cases with the contemporaneous canine population of the Canary Archipelago to analyse breed distribution. In line with former studies, we found histiocytomas mostly affect young dogs (2, IQR 1–5) and mast cell tumours affect middle-to-old dogs (8, IQR 6–10) with grade 1 affecting at younger ages (6.5, IQR 6–8) than both grade 2 (8, IQR 6–10 years) and grade 3 (9, IQR 7–11). Histiocytomas and plasmacytomas showed a similar anatomical distribution appearing mainly on the face, head and neck regions while mast cell tumours occur mainly on limbs and trunk. Higher risk for mast cell tumours and histiocytomas were found for Bulldog-related breeds such as Boxer (ORMCT = 23.61, CI95%: 19.12–29.15, ORHCT = 10.17, CI95%: 6.60–15.67), Boston Terrier (ORMCT 19.47, CI95%: 7.73–49.05, ORHCT 32.61, CI95%: 11.81–90.07) and Pug (ORMCT 8.10, CI95%: 5.92–11.07, ORHCT 7.87, CI95%: 4.66–13.28) while Chihuahua dogs showed significantly less risk (ORMCT 0.18, CI95%: 0.09–0.33, ORHCT 0.41, CI95%: 0.21–0.78). Notably, the Canarian Mastiff, a local breed, had a low risk of suffering from a mast cell tumour which raises the question of whether this relates to a genetic peculiarity of this breed or some husbandry and environmental factor.  相似文献

A high number of reported canine leptospirosis cases occurred in Washington State from 2004 to 2006. This prompted a serosurvey of healthy dogs from around the state to determine the distribution of exposure risk and to provide insight into serovar epidemiology in the region. In addition, a convenience sample of sera from injured raccoons was also tested, and clinical serological data from the Washington Animal Disease Diagnostic Laboratory were examined. The proportion of dogs with an antibody titre (>or=1:100) to any serovar was 27/158 (17.1%, 95% CI 11.6-23.9), and that proportion among raccoons was 22/115 (19.1%, 95% CI 12.4-27.5) suggesting that the potential for exposure in Washington state is not uncommon. The most frequently detected serovars in healthy dogs were Autumnalis, Icterohemorrhagiae and Canicola, in clinical canine samples Autumnalis, Bratislava and Pomona were more frequent and in sick or injured raccoons Autumnalis, and Pomona were most frequently detected. Clinical canine serology demonstrated a late summer-fall seasonality that was consistent with other reports. An outbreak of canine leptospirosis occurred during 2004-2006 and was located primarily in western Washington counties, as were three reported human cases in 2005. Canine leptospirosis surveillance is an important tool for detecting human risk of exposure and may provide insights into which serovars are currently of clinical importance.  相似文献

Australian wildlife rehabilitators (AWR) are at increased risk of developing Q fever, a serious zoonotic disease caused by the intracellular bacterium Coxiella burnetii. Previous studies have suggested that Australian wildlife may be a potential C. burnetii infection source for humans. However, a recent serological survey of AWR found no association between C. burnetii exposure and direct contact with any wildlife species. To further explore the potential risk that wildlife may pose, this study aimed to identify associations between self-reported Q fever in AWR and risk factors for exposure to C. burnetii. An online cross-sectional survey was implemented in 2018 targeting AWR nationwide. Risk factors for self-reported Q fever were determined using multivariable logistic regression. Medically diagnosed Q fever was self-reported in 4.5% (13/287) of unvaccinated respondents. Rehabilitators who self-reported medically diagnosed Q fever were significantly more likely to: primarily rehabilitate wildlife at a veterinary clinic (OR 17.87, 95% CI: 3.09–110.92), have domestic ruminants residing on the property where they rehabilitate wildlife (OR 11.75, 95% CI: 2.91–57.42), have been educated at a High School/Technical and Further Education level (OR 10.29, 95% CI: 2.13–84.03) and be aged >50 years (OR 6.61, 95% CI: 1.60–38.35). No association was found between self-reported Q fever and direct contact with wildlife. These findings support previous work suggesting that AWR are at increased risk of C. burnetii infection and may develop Q fever potentially via exposure to traditional infection sources including livestock, other domestic animals, or contaminated environments, in association with their rehabilitation practices and lifestyle. Although Q fever vaccination is recommended for AWR, vaccine uptake is low in this population. Future studies should aim to determine the level of Q fever awareness and identify barriers to Q fever vaccination in this at-risk group. The difficulty in accessing the AWR population also highlights the need for a national centralized AWR database.  相似文献

A survey of canine lymphoma treatment strategies by veterinarians in first opinion practice was undertaken by sending questionnaires to 1000 randomly selected, first opinion small animal veterinary practices throughout England. Completed replies were received from 382 veterinarians. Ninety-five per cent of respondents had diagnosed canine lymphoma in the preceding 12 months. Eighty-seven per cent of respondents treated at least 50 per cent of the cases of canine lymphoma they diagnosed. A multidrug combination of vincristine, cyclophosphamide and prednisolone (COP) was the treatment protocol most commonly used. A doxorubicin-based treatment protocol was used by 2 per cent of respondents to treat canine lymphoma initially. The study suggests that, despite several reports of improved survival times with doxorubicin-based protocols, most veterinarians in first opinion practice in England treat canine lymphoma with COP.  相似文献

In several veterinary institutions, adjustments of CT machines have been made that allow for imaging of the standing horse. The risk of general anesthesia is eliminated and the shorter scan completion time reduces cost to clients. The objective of this retrospective, analytical study was to evaluate the technique, imaging diagnoses, feasibility, and image artifacts of multi-slice helical CT of horses’ distal limbs acquired under standing sedation. The CT images of 250 horses of various breeds, aged 3–23 years, that underwent standing distal limb CT were evaluated. Three observers assessed the CT images for artifacts and inter-observer agreement was calculated. Eighty-six percent (95% confidence interval (CI), 81–90) of the scans were carried out on the forelimbs, while 14% (95% CI, 10–19) were of the hindlimbs. A total of 65% (95% CI, 59–71) of horses that underwent standing sedated CT had single imaging diagnoses. Seventy-one percent (95% CI, 65–77) of the cases had unilateral lesions, 27% (95% CI, 22–33) had bilateral lesions and 2% (95% CI, 1–4) had no diagnosed lesions. The average CT acquisition time was 17.5 minutes (range = 15–20). The average number of acquisitions per horse was 1.7 (median = 1; range = 1–4). There was good to excellent agreement between all three observers for the presence of motion artifact in the metacarpo/metatarsophalangeal joints, identification of marked beam hardening artifact, mild solar/ skin dirt, and photon starvation artifact (kappa 0.61-0.80). No complications were encountered. Standing examination of the distal limb achieved diagnostic image quality that was obtained with minimal acquisition attempts and in a timely manner.  相似文献

Haemangiosarcoma is a relatively common malignant tumour in dogs, and one of the primary outcomes of interest for the Golden Retriever Lifetime Study. This study collects longitudinal data and samples from a cohort of golden retrievers, with the aim of identification of nutritional, genetic, environmental, lifestyle and reproductive risk factors for cancers and other important diseases in dogs. This analysis describes the accumulating data and samples, which are available for use by researchers to fulfil the study's objectives. As of September 2022, 233/3044 dogs enrolled in the study had been diagnosed with haemangiosarcoma (7.65%), with an incidence rate of 1.10 cases per 100 dog-years. Visceral haemangiosarcoma was the most common, affecting 211/3044 study dogs (6.9%). One hundred and twenty eight visceral haemangiosarcoma diagnoses specified the presence of splenic tumours (60.7%) and 119 specified the presence of cardiac tumours (56.4%). The probability of remaining without a haemangiosarcoma diagnosis declined from 100% from approximately 4 years of age, to a 12 year probability of 91.1% in intact females (95% CI 84.4%–98.3%), 60.7% in neutered females (95% CI 41.6%–88.6%), 72.9% in intact males (95% CI 62.9%–84.6%) and 70.0% in neutered males (95% CI 53.4%–92.0%). The 1 year survival probability for visceral haemangiosarcoma was 1.42% (95% CI 0.37%–5.47%); for cutaneous haemangiosarcoma, it was 84.6% (95% CI 67.1%–99.99%). The accumulated data and samples are a considerable resource for further investigation of canine haemangiosarcoma and have a potential role in translational medicine.  相似文献

Between 65% and 91% of human‐patient sonographers report musculoskeletal symptoms related to their work activities. Ergonomic risk factors associated with musculoskeletal symptoms and musculoskeletal disorders (MSDs) include force, repetition, and awkward postures of the upper extremities. We hypothesized that veterinary sonographers experience similar risk factor exposures as their colleagues in human‐patient sonography, and that work‐related exposures may lead to similar prevalence of musculoskeletal symptoms and disorders. The Occupational Safety and Health Administration and Society of Diagnostic Medical Sonography published MSD prevention guidelines in 2003. Similar guidance for sonographers examining animal patients does not exist. This cross‐sectional study was designed to evaluate the prevalence of musculoskeletal symptoms among veterinary sonographers and identify reported risk factors. A 59‐item survey questionnaire was administered via email to veterinary specialists likely to perform ultrasound. Musculoskeletal pain related to performing ultrasound exams was reported by 62% of the respondents. Musculoskeletal symptoms were significantly associated with female gender (odds ratio [OR], 4.55; 95% confidence interval [CI], 2.04–10.19), age (OR, 1.06; 95% CI, 1.01, 1.10), previous work‐related trauma (OR, 6.86; 95% CI, 1.71, 27.40), not consistently using a normal height chair (OR, 2.63; 95% CI, 1.19, 5.80), and 15°–45° abduction of shoulder (OR, 2.34; 95% CI, 1.11, 4.92) . It was concluded that the prevalence of musculoskeletal symptoms among veterinary sonographers was similar to that occurring in human‐patient sonographers. © 2012 Veterinary Radiology & Ultrasound.  相似文献

Methicillin-resistant Staphylococcus pseudintermedius (MRSP) has emerged as a highly drug-resistant small animal veterinary pathogen. Although often isolated from outpatients in veterinary clinics, there is concern that MRSP follows a veterinary-hospital-associated epidemiology. This study's objective was to identify risk factors for MRSP infections in dogs and cats in Germany. Clinical isolates of MRSP cases (n = 150) and methicillin-susceptible S. pseudintermedius (MSSP) controls (n = 133) and their corresponding host signalment and medical data covering the six months prior to staphylococcal isolation were analysed by multivariable logistic regression. The identity of all MRSP isolates was confirmed through demonstration of S. intermedius-group specific nuc and mecA. In the final model, cats (compared to dogs, OR 18.5, 95% CI 1.8–188.0, P = 0.01), animals that had been hospitalised (OR 104.4, 95% CI 21.3–511.6, P < 0.001), or visited veterinary clinics more frequently (>10 visits OR 7.3, 95% CI 1.0–52.6, P = 0.049) and those that had received topical ear medication (OR 5.1, 95% CI 1.8–14.9, P = 0.003) or glucocorticoids (OR 22.5, 95% CI 7.0–72.6, P < 0.001) were at higher risk of MRSP infection, whereas S. pseudintermedius isolates from ears were more likely to belong to the MSSP-group (OR 0.09, 95% CI 0.03–0.34, P < 0.001). These results indicate an association of MRSP infection with veterinary clinic/hospital settings and possibly with chronic skin disease. There was an unexpected lack of association between MRSP and antimicrobial therapy; this requires further investigation but may indicate that MRSP is well adapted to canine skin with little need for selective pressure.  相似文献

A survey of veterinary radiation therapy facilities in the United States was done in 2001 to determine the type of equipment available, radiation protocols used, case load, tumor types irradiated, as well as other details of the practice of radiation oncology. A total of 42 sites were identified and included 17 (40%) academic institutions, and 25 (60%) private practice external beam radiation facilities. The overall response rate was 79% (33/42 responded). Based on this survey there is substantial variation between facilities in all aspects ranging from equipment and personnel to radiation protocols and caseloads. American College of Veterinary Radiology boarded radiation oncologists direct 76% of the radiation facilities at academic institutions and 60% of the private practice facilities. Three facilities had orthovoltage radiation units only, and 30 facilities had mega-voltage equipment: cobalt 60 or linear accelerator. A total of 18 facilities had linear accelerators with three of these off site at a human radiation facility. Patient load information was available from 31 sites (74% of the radiation facilities in the United States), and based on the responses 2790 dogs and 1081 cats were irradiated in 2001. Canine mast cell tumors were the most frequently irradiated tumor. This represents the first survey of veterinary radiation facilities in the United States and provides information on the specialty of veterinary radiation oncology.  相似文献

BACKGROUND: It is challenging to differentiate congestive heart failure (CHF) from noncardiac cause of dyspnea. HYPOTHESIS: Circulating concentrations of atrial natriuretic peptide (NT-proANP), B-type natriuretic peptide (BNP), endothelin-I (ET-1), and cardiac troponin-I (cTnI) can be used to help distinguish between cardiac and noncardiac causes of dyspnea in dogs. ANIMALS: Forty-eight client-owned dogs admitted to a veterinary teaching hospital for respiratory distress. METHODS: Blood samples from patients were prospectively obtained. The etiology of dyspnea was determined by using physical examination, thoracic radiographs, and echocardiography. RESULTS: CHF was diagnosed in 22 dogs, and dyspnea of noncardiac origin (noHD group) was diagnosed in 26 dogs. Analyses revealed significant difference between groups for NT-proANP (geometric mean, 95% confidence [CI]; no HD: 0.26 nmol/mL, 95% CI 0.17-1.09; CHF: 1.38 nmol/mL, 95% CI 1.09-1.74 nmol/mL; P < .0001), BNP (noHD: 12.18 pg/mL, 95% CI 10.91-16.17 pg/mL; CHF: 34.97 pg/mL, 95% CI 23.51-52.02 pg/mL; P < .0001), and ET-1 (noHD: 0.32 fmol/mL, 95% CI 0.23-0.46 fmol/mL; CHF: 1.26 fmol/mL, 95% CI 0.83-1.91 fmol/mL; P < .0001). Plasma cTnI concentrations were not significantly different between groups (noHD: 0.29 ng/mL, 95% CI 0.12-0.72 ng/mL; CHF: 0.42 ng/mL, 95% CI 0.18-0.97, P = .53). Receiver operating curves indicated areas under the curve for NT-proANP, BNP, and ET-1 of 0.946, 0.886, and 0.849, respectively. CONCLUSIONS AND CLINICAL IMPORTANCE: Plasma NT-proANP, BNP, and ET-1, but not cTnI, appear useful for distinguishing between dogs with cardiac and noncardiac causes of dyspnea, with plasma NT-proANP having the highest sensitivity (95.5%) and specificity (84.6%).  相似文献

A survey was carried out to investigate the occurrence of hard tick species (Acari: Ixodidae) infesting domestic dogs in Hungary. Forty veterinary clinics from a wide geographical area were asked to collect hard ticks from dogs and to complete a questionnaire. In total, 25 veterinary clinics submitted 900 ticks from 310 dogs. Intensity of infestation ranged from one to 78 per dog. The most preferred sites of tick attachment in decreasing order were head, neck and legs. The majority of ticks (91.7%) were adults, which were identified to species level, the others were nymphs. Six species were found: Dermacentor reticulatus (48.9%), Ixodes ricinus (43.2%), Ixodes canisuga (5.6%), Haemaphysalis concinna (2%) and there was one specimen of both Dermacentor marginatus and Ixodes hexagonus. Single species infestation with I. ricinus or D. reticulatus was found on 145 (46.8%) and 120 animals (38.7%), respectively. Mixed infestation caused by these two species was detected on 24 dogs (7.7%). I. canisuga and H. concinna were found on seven and five dogs, respectively. D. reticulatus and I. ricinus were collected almost throughout the year, except for a single month. The activity peaks were in spring and in autumn for both species. Based on clinical signs, canine babesiosis was diagnosed by the veterinarians in 66 (21.3%) tick infested dogs. These dogs were more frequently infested with D. reticulatus than the others. Our data contribute to the understanding of geographical and seasonal distribution of ixodid tick species infesting dogs in Hungary. The implication of these data, for the risk of canine tick borne diseases is discussed.  相似文献

Background: Interpretation of blood smears is commonly used to provide rapid laboratory evaluation of animals in veterinary emergency practice, but the accuracy of results of blood smear interpretation by emergency room personnel (ERP) compared with evaluation by trained veterinary clinical pathology personnel is unknown. Objective: The goal of this study was to compare blood smear evaluation by ERP with that of clinical pathology personnel. Methods: All animals that had a CBC determined by a diagnostic laboratory and had blood smears evaluated by personnel at the Foster Hospital for Small Animals Emergency Room between September 2008 and July 2009 were eligible for study inclusion. ERP who evaluated blood smears completed standardized forms with estimates of the WBC and platelet counts and evaluation of RBC and WBC morphology. Results from point‐of‐care assessment were compared with automated or manual results reported by the veterinary diagnostic laboratory. Results: One hundred and fifty‐five blood smears were evaluated. There was moderate agreement (κ value, 0.63; 95% confidence interval [CI]: 0.52, 0.74) between estimated platelet counts by ERP and automated counts. Poor agreement was found between estimated WBC counts by ERP and automated counts (κ value, 0.48; 95% CI: 0.37, 0.60). Specific abnormalities with a high likelihood of clinical significance, eg, toxic change, nucleated RBCs, spherocytes, hemoparasites, and lymphoblasts, were not predictably identified by ERP. Conclusions: ERP interpretation of canine and feline blood smears should be used cautiously and should not replace evaluation by a veterinary diagnostic laboratory.  相似文献

Objectives : The diagnostic utility of routine faecal examinations can be greatly enhanced through an appreciation of risk factors most commonly associated with endoparasitism. Methods : From a sample of 6578 canine patients presenting to a veterinary teaching hospital between 1996 and 2006, this study used univariate and multi‐variable techniques to examine putative signalment, medical history and demographic factors predisposing dogs to intestinal parasites. Results : Age and median household income were the strongest predictors of endoparasitism. The odds of a patient being diagnosed with endoparasites were 0·82 times smaller for every 1 year increase in age (OR=0·82, 95% CI: 0·80 to 0·84) and for every $10,000 increase in median household income, the odds were 0·86 times lower (OR=0·86, 95% CI: 0·83 to 0·89). The variables gender, neuter status, month of diagnosis, admitting clinical service and primary diagnosis were not significant predictors. Animals that were presented for underlying medical conditions were less likely to have parasites and the presence of diarrhoea was associated with 76% lower odds of endoparasitism compared to healthy animals (OR=0·76, 95% CI: 0·64 to 0·90). Clinical Significance : Clinicians should maintain a high index of suspicion for parasites in younger patients that live in high population density and low income neighbourhoods.  相似文献
