摘要:

Thoracic radiographs and electrocardiograms from 137 dogs with heartworm infection were independently evaluated and comparisons were made of (1) the presence or absence of right ventricular enlargement as assessed by these two diagnostic tests and (2) the presence or absence of right‐sided congestive heart failure relative to the degree of right ventricular enlargement and ECG criteria of RVH.Radiographic evidence of severe, but not moderate, right ventricular enlargement was associated with right‐sided congestive heart failure. Similarly the presence of three or more, but not fewer than three, ECG criteria of RVH were associated with right‐sided congestive heart failure. If either the thoracic radiographs or the ECG indicated that severe right ventricular enlargement was absent, right‐sided congestive heart failure was seldom present. The most accurate correlation of the radiographic evaluation of severe right ventricular enlargement was afforded by the presence of three or more ECG criteria of RVH. ECG criteria of RVH such as R/Sv4, + Tv10MEAx, and S11are highly specific tests; while SV2is a highly sensitive but not highly specific test. The ECG is a good confirmation test of the presence of severe right ventricular enlargement and is a good exclusion test for the absence of right‐sided congestive hear

摘要:

Radiographic, historical, clinical signs, and surgical and histopathologic findings of six dogs with diagnosed cystic uterus masculinus are given. The condition was seen in aged dogs between 4 and 15 years (mean of 8.8 years). There was no breed predisposition, although the larger breeds were involved in this study. The predominant clinical signs were constipation, dysuria and anuria. Lateral survey recumbent abdominal radiographs coupled with negative‐or positive‐contrast cystography were useful in delineating the bladder and the urethra, thus revealing the smooth‐contoured, asymmetrical fluid‐filled viscus in the caudal abdomen. The bi‐horned cysts were connected to the dorsal urethra through a short blind‐ending pedicle. The nonseptic, aspermic, cystic fluid averaged 146.7 ml (range of 100–200 ml). The predominant epithelial lining cells seen were simple columnar to pseudostrati

摘要:

This case history report describes the clinical, radiographic, and histopathologic features of an osteosarcoma with an associated pathologic fracture in a 6‐month‐old dog. A 6‐month‐old intact male Bloodhound was presented with a primary complaint of a right forelimb lameness of one month's duration. In radiographs, a minimally displaced transverse fracture of the proximal humeral metaphysis was seen. There was extensive cortical bone destruction at the fracture site and minimal periosteal new bone suggestive of a primary bone tumor with a pathologic fracture. Biopsy specimens demonstrated neoplastic mesenchymal cells producing osteoid compatible with a diagnosis of osteosarcoma. This case history report constitutes the youngest reported canine osteo

摘要:

B‐mode ultrasonography using a 7.5 megahertz (MHz) transducer was performed on 95 equine cadaver eyes submerged in a water bath. Identification and measurement of the anterior to posterior diameters of the intraocular structures and of the axis bulbi was done. The dorsal ventral axis of the eye was also measured. The eyes were then frozen, sectioned in a saggital plane and the same measurements were made using calipers. Two sets of measurements were then compared statistically.With the exception of the cornea and the dorsal ventral axis measurements of male horses there was no statistically significant difference in the measurements obtained by the two methods.The use of B‐mode ultrasonography at a frequency of 7.5 MHzto examine the architecture of the equine eye is suggested as a valuable clinical tool. Biometry of the intraocular structures at this frequency may be reasonably accur
