Three dogs were presented for investigation of recurrent pyrexia of unknown origin, chronic vomiting and respiratory distress, respectively. One dog was markedly underweight and the other two were cachexic. Physical examination and initial diagnostic tests failed to establish the underlying cause of the presenting signs. Thoracic radiographs were within normal limits for the age of the dog. In each case there was a high index of suspicion for an occult neoplastic process in view of the profound unexplained weight loss present. High-resolution computed tomography (HRCT) of the thorax was performed. The lung fields were divided into three zones for analysis and a novel classification scheme was used to describe the HRCT findings in each zone. Postmortem examination and histopathology confirmed the presence of an infiltrating metastatic carcinoma in all three cases. The HRCT changes correlated closely with the pathological findings. The authors conclude that HRCT of the lung should be considered for pulmonary metastatic screening in the dog and introduce a classification system for HRCT findings, based on terminology used in human medicine. 相似文献

Prostatic carcinoma in two cats 总被引：1，自引：0，他引：1

Clinical, radiological and pathological features of two cats with prostatic carcinoma are reported. In both cats the presenting history included signs of lower urinary tract disease with haematuria and dysuria. Prostatomegaly was visible radiographically in one cat; an irregular intraprostatic urethra was seen on retrograde contrast urethrography in both cats. In one of the cats, neoplasia was suspected on the basis of a transurethral catheter biopsy. Following a poor response to palliative treatment in both cases, euthanasia was performed with histological confirmation of the diagnosis. 相似文献

Summary The writer discusses the selection work performed at the Max-Planck-Institute at Cologne-Vogelsang.
Attention was particularly concentrated on finding crosses with wild species resistant to diseases and plagues. The writer
discusses in turn the results obtained with resistance toPhytophthora infestans, Alternaria solani, Rhizoctonia solani, Streptomyces scabies, Spongospora subterranea, Synchytrium
endobioticum, virus diseases,Heterodera rostochiensis and Colorado beetle.
He also refers to various difficulties that occur in crosses with wild species.
Zusammenfassung Der Verfasser bespricht die Selektionsarbeit, die im Max-Planck-Institut in K?ln-Vogelsang verrichtet worden ist. Die Aufmerksamkeit war vor allem darauf konzentriert, Kreuzungen mit Wildarten zu suchen, die resistent sind gegen Krankheiten und Sch?dlingsplagen. Nacheinander bespricht der Verfasser die Ergebnisse, die erreicht worden sind mit der Resistenz gegenPhytophthora infestans, Alternaria solani, Rhizoctonia solani, Streptomyces scabies, Spongospora subterranea, Synchytrium endobioticum, Viruskrankheiten,Heterodera rostochiensis und Kartoffelk?fer. Ferner nennt er einige Schwierigkeiten, die bei Kreuzungen mit Wildarten entstehen.
Résumé L'auteur donne un exposé sur l'oeuvre sélectionnaire, entreprise à l'Institut-Max-Planck à Cologne-Vogelsang. Une attention particulière a été apportée notamment à la recherche de croisements avec des éspèces sauvages résistant aux maladies et aux pestes. L'auteur traite ensuite des résultats que donne la résistance àPhytophthora infestans, Alternaria solani, Rhizoctonia solani, Streptomyces scabies, Spongospora subterranea, Synchytrium endobioticum, maladies virologiques,Heterodera rostochiensis et au doryphore. Pour conclure, il traite de quelques difficultés que soulèvent les croisements avec des variétés sauvages.相似文献

Ultrasonographic Imaging of the cervical trachea was performed with the neck in both a neutral and a hyperextended position in 10 dogs with tracheal collapse. Tracheoscopy was used to confirm a diagnosis of tracheal collapse. The ultrasound investigation was repeated in 10 dogs of similar size but without tracheal abnormality. The ultrasonographic findings of the affected dogs were compared with those of the normal group and showed an alteration in the shape of the tracheal lumen in the ventrodorsal projection. This study highlights the possibility of identifying changes in the shape of the tracheal lumen during ultrasound investigations as an aid to the diagnosis of tracheal collapse. 相似文献

A radiographic scoring system for features of osteoarthritis of the canine stifle joint was devised. Intra- and inter-rater agreement was assessed by calculation of unweighted kappa statistics. "Global score," "effusion," "osteophytosis," and "intra-articular mineralization" were all features that had acceptable reliability, but "subchondral sclerosis" did not. The scoring system was used in a 13-month prospective study of the radiographic progression of osteoarthritis of the stifle joint, secondary to cranial cruciate ligament deficiency, in 58 dogs. In the index stifle joints all features were characterized by significant change over time, but osteophytosis had the greatest degree of change. In addition, 40% of contralateral joints showed progressive osteophytosis. 相似文献

Lymph nodes are essential structures to be evaluated in an ultrasonographic examination of the feline abdomen. It was hypothesized that current technical proficiency would allow all feline abdominal lymph nodes to be identified ultrasonographically. Ten clinically normal, adult, domestic shorthair cats were examined using real-time compound ultrasonographic imaging. The medial iliac lymph nodes were visible in 100% of the cats, the jejunal lymph nodes in 90%, the hepatic lymph nodes in 70%, the aortic lumbar, the splenic, and the pancreaticoduodenal lymph nodes in 60% each, the ileocecal and the colic lymph nodes in 50% each, and the renal, the gastric, the sacral and the caudal mesenteric lymph nodes in 40%, 30%, 20%, and 10% of the cats, respectively. The inconsistent presence of lymph nodes, their poor echocontrast and interposed gas of the gastrointestinal tract explain the lower percentages of identification. The ultrasonographic length and diameter of the lymph nodes were determined. The majority of these measurements corresponded to those in the literature. We conclude that ultrasonography is a valuable tool for the identification and evaluation of most abdominal lymph nodes in the normal cat. Average ultrasonographic measurements are presented as a preliminary guideline for normal feline abdominal lymph nodes. ete 相似文献

A four-year-old Labrador retriever developed sudden-onset blindness, associated with bilateral uveitis, intraocular haemorrhage and retinal detachment. It had been imported into the UK from Sardinia 36 months before presentation. Haematological abnormalities included non-regenerative anaemia, thrombocytopenia and neutropenia. Serum and urine protein electrophoresis demonstrated a monoclonal gammopathy. An immunofluorescent antibody test for Ehrlichia canis was positive, with a titre of 1:320, confirming a diagnosis of chronic monocytic ehrlichiosis. This case highlights how the prolonged subclinical phase of monocytic ehrlichiosis could enable infected dogs to enter the UK without signs of disease. Chronic monocytic ehrlichiosis should be considered in dogs which have been imported from E canis-endemic countries and present with bleeding disorders and gammopathy, even if signs develop many years after importation. 相似文献

Forty dogs with clinical signs suggestive of upper respiratory tract disease underwent echolaryngography and laryngoscopy. Laryngoscopy was used as the definitive technique to diagnose laryngeal paralysis. The ultrasound investigation accurately indicated the presence of the paralysis and confirmed the uni- or bilateral nature of the disorder. Findings indicative of laryngeal paralysis included asymmetry or absence of motion of the cuneiform processes (30/30), abnormal arytenoid movement (16/30), paradoxical movement (9/30), caudal displacement of the larynx (2/30) and laryngeal collapse (1/30). Thirty dogs were found to be afflicted with laryngeal paralysis and ten had normal laryngeal motility. 相似文献

ULTRASONOGRAPHY OF LARYNGEAL MASSES IN SIX CATS AND ONE DOG 总被引：1，自引：0，他引：1
Ultrasonography of laryngeal abnormalities in small animals allows the identification of laryngeal masses because of the resulting distortion of normal structural/anatomical relationships. It also allows fine-needle aspirates to be taken with minimal risk of causing hemorrhage or edema affecting the already narrowed laryngeal lumen. Findings in six cats and one dog with laryngeal abnormalities are described. 相似文献
