The case records of and histopathologic findings in 57 dogs with nonangiogenic and nonlymphomatous splenic sarcomas were reviewed. Splenic neoplasms in these dogs included leiomyosarcoma, fibrosarcoma, undifferentiated sarcoma, liposarcoma, osteosarcoma, chondrosarcoma, myxosarcoma, rhabdomyosarcoma, and fibrous histiocytoma. The clinical signs associated with splenic sarcoma included anorexia or decreased appetite, abdominal distention, polydipsia, lethargy, vomiting, weight loss, and weakness. An abdominal mass was detected in 86% of the dogs by use of abdominal palpation (63%), and/or abdominal radiography (74%). The diagnosis was based on histopathologic findings in the spleen. Abdominal exploratory surgery was performed on 43 of the 57 dogs. Twenty-seven dogs were treated by splenectomy, and 16 were euthanatized at the time of surgery because of widespread metastatic lesions. Of the 14 dogs on which surgery was not performed, 11 were euthanatized on the basis of results of preoperative diagnostic tests, and the remaining 3 dogs had splenic neoplasms that were incidental findings at necropsy. Of the 27 surgically treated dogs, 5 died in the immediate postoperative period, 12 died or were euthanatized within 1 year after splenectomy, and only 5 dogs survived greater than or equal to 1 year. Three dogs were lost to follow-up evaluation, and 2 were still alive 6 and 7 months after surgery. The median survival time of the 22 dogs for which survival was known was 2.5 months. The median survival time for 11 dogs with no obvious metastasis at the time of splenectomy was 9 months.(ABSTRACT TRUNCATED AT 250 WORDS)

In this survey for the presence of the feline leukaemia virus (FeLV) in the Singapore domestic cat population, the sera of two different groups of unvaccinated mainly short haired cats which were over 6 months old were sampled. The FeLV enzyme-linked immunoadsorbent assay (ELISA) diagnostic test kit was used to detect the presence of the FeLV group specific (gs) antigens in the blood of cats. Of the 345 clinically healthy cats surveyed, 34 sera (9.9%) were found to be positive and of the group of 123 cats with clinical signs such as chronic wasting, marked by anaemia, anorexia and lethargy, 33 sera (26.8%) were found to be positive. From the time of diagnosis of a viraemia, 70% of cats will die within 20 months. The results are therefore indicative that annually a small proportion of cats in the local environment will die from a FeLV infection. This survey reflects the natural distribution of an infectious oncovirus in a susceptible host population which is unaffected by any control programme to interfere with the normal sequence of events of host virus interactions.

Supplementing the food of Heidenhain pouch gastric fistula dogs with a KC1 product greatly extends the survivability of these dogs. Since there is a continuous discharge of gastric juice from the pouch to the exterior each time a meal is consumed, clinical signs such as dehydration, anorexia, rough hair coat and lethargy usually occur within a few months after gastric pouch surgery and, unless extensive supportive measures are taken, most dogs will die shortly thereafter. The five dogs which did not receive KC1 supplementation died within 6 months after surgery with a mean survival time of 2.4 +/- 0.9 months. Seven dogs that received a daily oral supplement of 1.5 g KC1 (20 mEq) in their food have, on average, survived more than ten times longer than dogs which received no KC1 supplementation, with a mean survival time of 25.1 +/- 4.4 months. All KC1 supplemented dogs survived for more than 15 months with three dogs currently surviving for 36-40 months. When two dogs experienced decreased serum potassium, sodium and/or chloride levels and showed clinical signs of electrolyte imbalance despite receiving daily oral KC1 supplementation, intervention with intravenous (i.v.) lactated Ringer's solution and increased amounts of oral KC1 supplement reversed these symptoms within 1-2 weeks. Dogs that received only i.v. Ringer's therapy died with 1 week of the onset of clinical signs. Daily oral KC1 supplementation, careful observation of behavior and eating patterns, and routine physical examinations and serum electrolyte measurements can greatly extend the life expectancy of dogs with Heidenhain pouch gastric fistulas.

An 8-year-old sexually intact male llama was euthanatized because of obstruction of the penile portion of the urethra and rupture of the urinary bladder. Clinical signs of obstruction included anorexia, lethargy, teeth grinding, straining to defecate, inability to urinate, and tense abdomen. Laboratory findings included anemia, leukocytosis with left shift, high serum urea nitrogen, creatinine, and phosphorus concentrations, and low serum chloride concentration. Necropsy revealed ruptured urinary bladder and acute fibrinous peritonitis. A firm, gray, nonmineralized urethral plug occluded the penile portion of the urethra for a distance of 14 cm in the midpenile region, distal to the sigmoid flexure of the penis. The urinary bladder mucosa and the urethra had microscopic evidence of chronic inflammation. Escherichia coli, Klebsiella sp, and alpha-streptococci were isolated from the urethral plug.

The records of 15 dogs diagnosed as having juvenile cellulitis (juvenile pyoderma, puppy strangles) were evaluated for clinical, laboratory, and therapeutic results. Mandibular lymphadenopathy was observed in 14 dogs, and was not associated with skin lesions in 5 dogs. Edema, pustules, papules, or crusts were noticed periorally, periocularly, on the chin or muzzle, or in the ears of those dogs with skin lesions. Eight dogs were lethargic; fever and anorexia were inconsistent findings. Four dogs had signs of pain on manipulation of their joints. Complete blood counts revealed leukocytosis with neutrophilia in 4 dogs, and normocytic, normochromic anemia in 6 dogs. Three dogs had suppurative lymphadenitis with many neutrophils. Cytology of the aspirate of pustules or abscesses in 6 dogs revealed many neutrophils without bacteria. Coagulase-positive Staphylococcus spp were isolated from draining lesions in 2 dogs. Intact abscesses and lymph nodes were negative for bacterial growth in 4 dogs. Three of these dogs were being administered antibiotics at the time of bacterial culturing. Cytology of the aspirates of joints in 3 of the 4 dogs with joint pain revealed suppurative arthritis with no bacteria, and the aspirates were negative for bacterial growth on culturing, although all 3 dogs were being administered antibiotics at the time of culturing. Of 12 dogs initially treated with antibiotics, only 4 (33%) responded favorably; the other 8 dogs were then given antibiotics and corticosteroids. Three dogs were initially given antibiotics and corticosteroids. All dogs treated concurrently with antibiotics and corticosteroids responded favorably. One of these dogs had a relapse after treatment was discontinued. The concurrent arthritis in 4 of the dogs resolved with treatment of the juvenile cellulitis and did not redevelop once the medication was discontinued. Concurrent treatment with antibiotics (cephalosporins) and prednisone (2.2 mg/kg of body weight/day) was the most consistently effective treatment in the dogs in this study.

Inoculation of mice with high doses of Streptococcus suis type 2 caused depression, anorexia, lethargy and sometimes death. This was prevented by prior inoculation of whole immune pig serum, the IgM and IgG fractions of immune pig serum and serum enriched with antibody to surface antigens. Clinical signs were not prevented by prior inoculation of pre-immune serum or serum depleted of antibody to surface antigens. Serum fractions that were protective in vivo were also opsonic in vitro. Western blot analysis identified two antigens of 44 and 78 kd that were recognized strongly by protective sera and a further four of 86, 94, 130 and 136 kd that were recognized less intensely.

Black walnut toxicosis was diagnosed in 10 horses at one stable. The time from exposure to shavings to development of clinical signs was 8 to 12 hours. Most common clinical signs were moderate to severe laminitis (Obel grade 2 or 3), pitting edema of the distal portion of the limbs, and rapid respiratory rate. Two horses had clinical signs of colic and 2 other horses had anorexia and lethargy. All 10 horses recovered without complications.

The medical records of 59 dogs with renal amyloidosis were reviewed. Most dogs with amyloidosis were greater than 6 years old, and females were affected more often than males. Beagles, Collies, and Walker Hounds were at increased risk, whereas German Shepherd Dogs and mixed-breed dogs were at decreased risk. Common historical findings were anorexia, polyuria, polydipsia, lethargy, vomiting, and weight loss. Common laboratory findings were leukocytosis, lymphopenia, nonregenerative anemia, hypercholesterolemia, azotemia, hyperphosphatemia, metabolic acidosis, isosthenuria, cylindruria, and proteinuria. Proteinuria was moderate to severe in most dogs, as assessed by qualitative determination of urine protein concentration, urine protein/urine creatinine ratio, and 24-hour urine protein excretion. Conservative medical management was of little value, and survival ranged from 3 to 20 months in 12 dogs for which this information was available. Moderate to severe diffuse global glomerular amyloidosis was detected in all dogs. Medullary amyloid deposition was multifocal and less severe, but was evident in most dogs. Secondary tubulointerstitial and glomerular lesions were mild or absent in most dogs. Thromboembolism was identified in approximately 14% of affected dogs, underlying inflammatory disease in 37%, and neoplasia in 20%. Laboratory indicators of renal function correlated poorly with histologic lesions, with the exception of glomerular amyloid deposition and "chronic renal disease" index with endogenous creatinine clearance.

Chronic renal failure was diagnosed in 15 Bull terrier dogs. The dogs ranged in age from one to 8 years. History and clinical findings typically included lethargy, anorexia, polyuria, polydipsia and weight loss. Affected dogs were azotaemic, had elevated serum phosphate and cholesterol, and proteinuria was apparent in all dogs tested (13/13). The concentration of urine was consistently in the nil to minimally concentrated range (specific gravities 1.011-1.017). In those dogs necropsied, both kidneys were approximately two-thirds normal size, tough in consistency, with a pale cortex and a finely nodular capsular surface. Histologically, there was marked nephron loss, diffuse interstitial fibrosis and focal dense radial fibrosis which was especially evident in the renal medulla. Tubular dilation was widespread with focal mineralisation of tubular epithelium and adjacent basement membranes. Glomeruli were often shrunken and segmentally fibrotic. Some Bowman's spaces were extremely dilated. Many less severely affected glomeruli had thickened basement membranes.

Copper poisoning developed in 1 adult and 3 juvenile llamas after excessive dietary intake of copper resulted in an incorrect copper:molybdenum ratio. Total dietary copper was determined to be 36 mg/kg of feed, with a copper:molybdenum ratio of 16.6:1. Clinical signs associated with the toxicosis included acute onset of anorexia and lethargy. Liver enzyme activities (aspartate amino transaminase, lactate dehydrogenase, gamma-glutamyl transferase) and serum copper concentration were high in specimens obtained within 48 hours before death. Gross necropsy findings were limited to mild hepatomegaly. Histologically, hepatic lesions included acute massive necrosis of hepatocytes with and without bile duct proliferation, double hepatic plates with loss of orientation, anisocytosis, anisokaryosis, and an intralobular mosaic pattern of necrosis involving half of the hepatocytes. Analysis of hepatic copper concentrations suggested that juvenile llamas develop signs of poisoning at lower hepatic copper concentrations, compared with adults.
