Three male Shar-pei dogs and one female spayed Boxer dog ranging in age from 4 years, 4 months to 7 years, 8 months had 4-7-week histories of diarrhea, progressive anorexia, weight loss, and vomiting. The dogs were depressed, lethargic, and hypoalbuminemic, with losses of 23-39% of body weight. Endoscopic examination revealed gastric ulceration with areas of mucosal hyperemia and pallor. Small nodules with occasional central depressions were present in three dogs. Gastric and proximal duodenal mucosal biopsies showed neoplastic lymphocytes infiltrating the lamina propria, with invasion of the superficial and glandular epithelial basement membrane. Immunohistochemical evaluation of two dogs was negative for anti-canine IgG and positive for anti-CD3. Necropsy of the Boxer and two Shar-peis confirmed epitheliotropic gastric and small intestinal lymphoma in all three dogs, with mesenteric lymph node and hepatic involvement in two and one dog, respectively.

Simian T-cell leukemia virus type 1 (STLV-1), a type C retrovirus associated with leukemia/lymphoma in Old World monkeys, is closely related to human T-cell leukemia virus type 1, the etiologic agent of adult T-cell leukemia/lymphoma in humans. In a colony of 3200 baboons, the prevalence of antibodies to STLV-1 is more than 40%. Seropositivity is more frequent in female baboons than in males and increases with age. Of 27 STLV-1 antibody-positive baboons with non-Hodgkin's lymphoma, 20 were females and 7 were males, ranging in age from 3 to 21 years (mean, 13 years). Non-Hodgkin's lymphoma was not found in STLV-1 antibody-negative baboons. Clinical signs and laboratory findings were variable but generally included lethargy, low body weights, anemia, dyspnea, lymphadenopathy, hepatosplenomegaly, pneumonia, nodular skin lesions, and leukemia with or without multilobulated lymphocytes in peripheral blood. Radiography revealed pulmonary infiltrates consistent with pneumonia in 17 of the baboons. Serum chemical values were normal except for hypercalcemia in one baboon. Lymphocytosis was found in 18 of the baboons, with leukemia diagnosed in 11. At necropsy, variable enlargement of lymph nodes and other lymphopoietic tissue was usually found. Pale tan to white space-occupying foci typical of proliferative lymphoid tissue were often found in various organs, including lungs, spleens, livers, skin, and hearts. The lungs in 14 baboons had thickened pleuras, congestion,edema, and large tan to brown areas of consolidation.(ABSTRACT TRUNCATED AT 250 WORDS)

Intussusception, the invagination of a portion of the intestine into an adjacent segment, is the most common cause of intestinal obstruction in post neonatal children. Most cases are idiopathic, but in about 2-12% the intussusception evolves secondary to an underlying abnormality. Classically, there is sudden onset of attacks of screaming, accompanied by pallor, vomiting, and irritability in a previously health child. Some gradually become weaker and lethargic. We evaluated variations in presenting symptoms and outcome as related to age and time until admission. There were incidence peaks in the spring and autumn. 48% developed irritability, while 42% were described as apathetic. These results emphasize the importance of awareness that apathy can be a major presenting symptom. The younger the child, the greater the rate of success of reduction by hydrostatic pressure. In those admitted within 24 hours of onset, the rate of reduction was twice that in those admitted later. Awareness of atypical symptoms and early diagnosis may affect treatment and improve prognosis.

This study reviews all childhood intussusceptions treated over a 6 year period in a regional centre with six visiting general surgeons and two paediatricians. Clinical presentation, management, complications and outcomes were noted and an attempt was made to follow up all cases. There were 20 patients, with a median age of 6 months (range 10 weeks to 17 months). Only one patient had all four classical features of intussusception (pain, vomiting, 'red currant jelly' stools and abdominal mass). Seven patients were managed successfully by barium enema reduction, but 14 required operation, four following failed radiological reduction. There was one intestinal perforation due to attempted barium enema reduction and one patient required a reoperation for ileal gangrene following operative reduction. There were no deaths and there have been no subsequent recurrent intussusceptions although three cases were lost to follow up. There was a delay in diagnosis in some cases (average duration from onset to diagnosis was 34 h). Although delay was incurred by parents in some cases and in peripheral hospitals in others, there is a need for greater awareness by surgeons of the significance of subtle features such as pallor and lethargy in a child with persistent vomiting. Delay in diagnosis is likely to lead to an increased need for primary surgical intervention. Adverse features (age > 3 months or < 2 years; symptoms > 24 h; small bowel obstruction; dehydration > 5%) were predictive of an increased likelihood of surgical resection, and may help avoid inappropriate attempts at radiological reduction.(ABSTRACT TRUNCATED AT 250 WORDS)

Hypopituitarism is uncommon in elderly people. We report 12 cases of hypopituitarism diagnosed after the age of 60 (range 63-89, mean 74.9) years over a 10-year period. Aetiology was evident in eight cases, viz. pituitary tumour in six and previous post-partum haemorrhage and giant aneurysm of carotid artery in one each. The presentation was often non-specific with symptoms such as lethargy, pallor, falls, urinary incontinence, confusion, fever and flexion contractures. Subtle clues to the condition were missed in four cases resulting in delayed diagnosis. Although levels of pituitary trophic hormones are generally low in this condition, the thyrotrophin (TSH) was normal in seven cases in the present series. Normal levels of serum sodium and potassium did not exclude cortisol deficiency. Hormone replacement therapy resulted in improved quality of life. Physicians dealing with elderly patients should bear this easily treated condition in mind.

Dumping syndrome is infrequently reported in children, but has significant morbidity. It may be difficult both to diagnose and manage. Two children are reported who developed dumping syndrome after Nissen fundoplication. Symptoms occurred soon after the operation and included post-prandial pallor, sweating, lethargy and diarrhoea. Failure to thrive was a prominent feature. Typical biochemical changes included hyperglycaemia shortly after meals, followed by hyperinsulinaemia and reactive hypoglycaemia. Effective treatment was only achieved with continuous enteral feeding. Children undergoing fundoplication should be closely monitored for episodes of hypoglycaemia and unresponsiveness. The incidence of dumping syndrome after fundoplication may be underestimated, particularly in children.

Twenty-three episodes of anticoagulant rodenticide toxicity were found in 21 dogs during a retrospective study conducted at The Ohio State University Veterinary Teaching Hospital. Dyspnea (57%), lethargy (48%), coughing/hemoptysis (30%), and pallor (26%) were the most common presenting complaints. Prolonged activated clotting time (ACT), prolonged one-stage prothrombin time (OSPT), and prolonged activated partial thromboplastin time (APTT) were present in all dogs that had not received any prior therapy. Anemia (83%), thrombocytopenia (61%), hypoproteinemia (57%), positive fibrin degradation products (FDPs) (55%, six of 11 tested), and hyperfibrinogenemia (43%, six of 14 tested) were common hematological findings. Treatment included therapy with vitamin K1, blood products, and supportive care. The survival rate was 83%.

A three-year-old weimaraner was presented with lethargy, anorexia, neck pain and a soft fluctuant swelling in the thoracic inlet. A cough had been noted previously. Clinical examination revealed tachycardia, tachypnoea, pallor and a large subcutaneous swelling, with bruising, suggestive of a haematoma in the thoracic inlet. Thoracic radiographs revealed a cranial mediastinal mass which had the ultrasonographic appearance of fluid, and there was also a marked generalised interstitial lung pattern. Routine haematology revealed severe anaemia and thrombocytopenia, although coagulation tests were within normal limits. A diagnosis of immune-mediated thrombocytopenia was however made on the basis of a positive antiplatelet antibody test and a rapid response to prednisolone therapy. Furthermore, a tentative diagnosis of Angiostrongylus vasorum infection was suggested on the basis of clinical and radiographic findings, although no lungworm larvae were identified on faecal analysis. Despite initiating treatment with fenbendazole, the dog died suddenly. Postmortem examination revealed myocarditis, thrombosing arteritis, pneumonia and chronic membranoproliferative glomerulonephritis associated with A vasorum infection.

Cyclic vomiting syndrome is a disorder of unknown etiology that is characterized by its clinical pattern of rapid-fire, episodic (on-off) vomiting with interval wellness. The pattern is stereotypic within individuals and typified by a rapid onset during the night or early morning, rapid denouement, and associated symptoms of pallor, lethargy, anorexia, nausea, retching, vomiting, and abdominal pain. The vomiting appears to be triggered by a variety of physical and psychological stresses. The disorder usually begins in toddlers and resolves during adolescence. By definition, cyclic vomiting syndrome is an idiopathic disorder that requires exclusionary laboratory testing. Not only can it be mimicked by many specific disorders, eg, surgical, neurologic, endocrine, metabolic, renal, but within idiopathic cyclic vomiting syndrome there may be specific subgroups that have different mechanisms. Treatment options are improving at present and serotonergic agents have the most promise. Although the pathogenesis is unknown, there are now several tenable mechanisms including migraine, metabolic, neuroendocrine, and gastrointestinal. Cyclic vomiting syndrome may be a useful model for the study of emesis.

Preparturient hypocalcemia was identified in 4 cats in a specific pathogen-free colony between 1995 and 1996. All cats had an acute onset of clinical signs, 3 to 17 days prior to parturition. Signs of depression, weakness, tachypnea, and mild muscle tremors were the most common clinical signs, following by vomiting and anorexia. Additional abnormalities included hypothermia, third eyelid prolapse, dehydration, pallor, lethargy, flaccid paralysis, and hyperexcitability. Hematologic abnormalities included leukocytosis with neutrophilia and lymphopenia. Hypocalcemia was documented in each queen. Common serum biochemical abnormalities included high aspartate aminotransferase and creatine kinase activities. All cats responded to IV or SC administration of 10% calcium gluconate. Queens were then given calcium orally prior to and following parturition. The queens did not have additional complications for the duration of the gestational or lactational periods.
