A 28-month-old white male, 7 months status postenucleation for retinoblastoma, presented with lethargy, irritability, anemia, and thrombocytopenia. Bone marrow examination revealed almost total replacement of marrow elements with clumps of small round basophilic cells. Electron microscopic study of the marrow revealed clumps of cohesive tumor cells with intermediate junctions, establishing a diagnosis of metastatic retinoblastoma.

A prospective study was carried out to determine the effectiveness and tolerance of ftorafur (2.25 g/m2 daily for 5 days, repeated every 4 weeks) in previously treated patients with advanced squamous cell cancers of the head and neck. Seventeen patients were entered in the study; 15 were evaluable for drug toxicity, and 14 were evaluable for response. Three patients had mild nausea, three had mild-to-moderate lethargy, two had nonspecific generalized weakness, and two had severe stomatitis. Of 15 patients three experienced leukopenia (causing death in one) and four had thrombocytopenia (life-threatening to one). Response to treatment included: progressive disease (nine patients), stable disease (four), and complete response (one with no previous radiotherapy or chemotherapy).

Aplastic anemia in association with estrus was diagnosed in 6 pet ferrets. The ferrets had been examined because of anorexia, depression, and lethargy of 2-5 days' duration. Consistent clinical findings were pale mucous membranes and enlargement of the vulva. Hemorrhages were found in 3 ferrets. Hematologic findings included severe anemia, thrombocytopenia, granulocytopenia, and hypocellularity of the bone marrow. The aplastic anemia was attributed to prolonged estrogenic exposure in ferrets with protracted estrus.

The combination of mitozantrone, methotrexate and mitomycin (3M) gives a response rate of around 50% in patients with advanced breast cancer. The predominant toxicity is haematological. In this study, previously untreated patients were given 3M with increasing doses of mitozantrone (7-14 mg m-2) with recombinant human granulocyte colony-stimulating factor (metHuG-CSF) (filgrastim) to prevent marrow toxicity. Doses administered were 7 mg m-2 mitomycin i.v. 6 weekly, methotrexate i.v. 35 mg m-2 (maximum 50 mg) 3 weekly and mitozantrone i.v. 3 weekly as follows: 7 mg m-2, six patients (group 1); 10 mg m-2, six patients (group 2); 12 mg m-2, six patients (group 3); 14 mg m-2, six patients (group 4); all on day 1 for six cycles at the assigned dose. All patients received filgrastim (Amgen 0.3 mg ml-1) at a dose of 5 micrograms kg-1 subcutaneously daily on days 4-17 of each cycle. All treatment was given on an out-patient basis. A total of 24 patients were entered into the study. The median age was 63 years (range 48-75). ECOG performance status was 0 in ten, 1 in 11 patients and 2 in three patients. Locoregional disease alone was present in seven patients. The remainder had one or more sites of metastases. The actual dose administered to the 24 patients was as follows. The six patients in group 1 all completed six courses of treatment as per protocol. In group 2, three patients completed six courses, two stopped because of toxicity after one and four courses and one had progressive disease after one course. In group 3, three patients completed and three stopped early because of progressive disease. In group 4, two patients completed, one progressed after four courses and three responding patients stopped treatment because of toxicity. The maximum tolerated dose of mitozantrone in the 3M combination was 12 mg m-2. The use of filgrastim with increasing doses of chemotherapy prevents neutropenia, but other toxicities, namely thrombocytopenia and lethargy, then become dose limiting.

Erythema multiforme major and disseminated intravascular coagulation developed in a dog 24 hours after exposure to a d-limonene-based insecticidal dip. Clinical signs included severe lethargy and weakness, ulceration of the oral mucosa, and erythematous serpiginous, annular, and arciform lesions on the head, trunk, and limbs. Clinicopathologic abnormalities included leukocytosis with neutrophilia, normocytic normochromic anemia, thrombocytopenia, prolongation of prothrombin and partial thromboplastin times, increased fibrin degradation products, hypoproteinemia, hyponatremia, hypochloremia, azotemia, high serum alanine aminotransferase and alkaline phosphatase activities, and high serum bilirubin concentration. Despite intensive supportive care, the dog developed severe intrathoracic and abdominal hemorrhage and died. Necropsy revealed severe diffuse epidermal necrosis and widespread hemorrhage within organs. Insecticidal dips containing d-limonene have the potential to induce various toxic effects, including, possibly, erythema multiforme major, and should be used cautiously.

A 7-year-old spayed Louisiana Catahoula Leopard dog was examined to determine the cause of shifting forelimb lameness, anorexia, and lethargy. The dog was pyrectic and had splenomegaly, thrombocytopenia, and nonregenerative anemia. Examination of a bone marrow aspirate revealed hypocellularity with normal maturation of erythroid and granulocytic cell lines; however, approximately half of the cells were large undifferentiated blast cells. These cells were identified as megakaryoblasts, using immunohistochemical techniques to detect reactivity for Factor VIII-related antigen and platelet glycoprotein IIIa. Necropsy revealed diffuse neoplastic involvement of the spleen, liver, lungs, bone marrow, and lymph nodes. Cellular infiltrate was characterized by a mixture of megakaryoblasts and typical megakaryocytes. Megakaryoblastic leukemia (M7) is the designation proposed by the Animal Leukemia Study Group for myeloproliferative neoplasms of megakaryocytic lineage.

Selective intraarterial infusion of papaverine is used in the treatment of symptomatic cerebral vasospasm. The authors report two episodes of severe thrombocytopenia in a patient that were related to intraarterial administration of papaverine. A 70-year-old man with a right internal carotid artery aneurysm underwent craniotomy and aneurysm clipping. He became lethargic 8 days after the hemorrhage occurred. Cerebral angiography revealed moderate vasospasm. In addition to hypervolemic-hypertensive therapy, the patient was treated on two occasions with intraarterial administration of papaverine. Within 24 hours of both treatments he developed severe thrombocytopenia. On one occasion epistaxis requiring transfusion of blood products occurred. Laboratory data support the diagnosis of immune-mediated papaverine-induced thrombocytopenia. The authors conclude that intraarterial administration of papaverine for treatment of vasospasm can be associated with severe, rapidly reversible thrombocytopenia.

A 7-year-old boy presented to the emergency department with severe hypotension and lethargy after a rattlesnake bite. He developed anaphylaxis to antivenom and required intubation, epinephrine, antihistamines, and steroids. Severe rhabdomyolysis and myoglobinuric kidney failure developed over 24 hours, with a peak creatine phosphokinase level of 214,500 units/L. Severe hypocalcemic tetany was treated with replacement therapy. Local wound swelling was never severe and the patient had no coagulopathies. Marked motor weakness improved with antivenom administration. Because of the myotoxic and neurologic effects in the absence of fibrinogenolysis/thrombocytopenia and minimal tissue signs, as well as the similarity to a previously reported case from our area, the envenomation was most likely caused by a Mojave rattlesnake.

Infection of 60 to 90% of neutrophils with the protozoa, Hepatozoon canis, was detected in 2 dogs. Clinical signs included lethargy, anorexia, and weight loss. Both dogs had severe anemia, leukocytosis, and thrombocytopenia as well as hypoalbuminemia, hyperglobulinemia, and high activities of serum alkaline phosphatase and creatine kinase. Both dogs were treated with imidocarb dipropionate and doxycycline. One dog recovered clinically, with disappearance of parasites from WBC. The other dog died, despite treatment. Necropsy revealed widespread dispersion of schizonts in the parenchymal tissues, but no involvement of skeletal muscle tissues. The disease syndrome that has been identified in the Texas Gulf region is characterized by gait abnormalities associated with multifocal pyogranulomatous myositis, thus, it is distinct clinicopathologically from the syndrome observed in these 2 dogs.

Newborn lambs which had been given colostrum from a single cow developed thrombocytopenia and seven died. The clinical signs included purpura, haemoglobinuria, melaena, dullness and lethargy. The lambs died at one to two days old. Post mortem examination revealed widespread haemorrhages throughout the body. Lambs given small amounts of colostrum developed a transient thrombocytopenia but did not die.
