Thrombocytopenia in horses may be idiopathic or secondary to chronic infectious or inflammatory diseases (eg, equine infectious anemia, lymphosarcoma), drug administration, bone marrow depression, myelophthisic disease, or disseminated intravascular coagulation. This report describes EDTA-dependent pseudothrombocytopenia in a horse. Platelet counts for blood containing EDTA were consistently less than reference range, but platelet counts of blood containing heparin were within reference range. When thrombocytopenia is diagnosed in horses without clinical evidence of a bleeding tendency, EDTA-dependent pseudothrombocytopenia should be considered. The diagnosis can be confirmed simply by screening blood films for platelet clumps and by comparing platelet counts of paired blood samples, one containing EDTA and the other containing heparin.

We studied four patients who presented a striking elevation of blood transaminases suggesting acute hepatitis. The post mortem histological examination of the liver revealed centrolobular necrosis that is commonly diagnosed as ischaemic hepatitis. The liver necrosis arose from heart failure which was worsened by an acute anaemia in one patient and by a severe hypoxemia, due to respiratory failure, in another. In three subjects there was evidence of disseminated intravascular coagulation that may be responsible for aggravating the condition of liver hypoxia. The authors also review the literature on the various aspects of ischaemic hepatitis.

We report the case of a premature female newborn of the 35th gestational week with a congenital mesoblastic nephroma. The tumor was prenatally diagnosed in the 32nd week of gestation. By close sonographic controls, rapid enlargement was verified towards the end of the 35th week of gestation. This was probably caused by hemorrhage into the tumor. Anemia and postnatal disseminated intravascular coagulation followed. Cesarean section was done, because the anemia was suspected by Doppler sonographic evaluation. Disseminated intravascular coagulation could not be sufficiently controlled by conservative means but only by surgical removal of the tumor. The tumor turned out to be a congenital mesoblastic nephroma by histologic evaluation. Despite postoperative anuria and catecholamine dependency, our patient eventually showed a very favourable outcome. Diagnosis, clinical behavior and therapy of this tumor with a generally good prognosis are described and discussed.

Very few data on the frequency and diversity of haematological abnormalities occurring in brucellosis in children have been reported. In the present study 110 children (56 boys and 54 girls; age range, 2 months to 14 years) with proven brucellosis were investigated to determine the haematological changes during the active course of this infection. Anaemia was detected in 48 (44%) patients, of whom four had evidence of haemolysis. Leukopenia occurred in 33% of the cases, with neutropenia and/or lymphopenia being the most striking features encountered. Thrombocytopenia was found in six (5%) patients and pancytopenia in 15 (14%) patients, of whom one developed disseminated intravascular coagulation. Clinically detectable bleeding occurred in five (4.5%) patients whose platelet counts were significantly low. Hypersplenism, haemophagocytosis and granulomatous lesions of the bone marrow appear to play a fundamental role in producing these abnormalities of the peripheral blood. Brucellosis may be considered in patients whose blood picture reveals haemolytic anaemia, leukopenia, thrombocytopenia or pancytopenia, particularly when the disease is epidemiologically suspected.

Assessment of peripheral blood counts and blood film analysis are frequently performed as diagnostic procedures in emergency medicine. Far fewer situations exist, however, in which these analyses are the main clue in establishing an emergency diagnosis. Artifacts can lead to wrong diagnosis, e.g. pseudo-thrombocytopenia, which is defined as a low platelet count resulting from a laboratory artifact. Severe neutropenia (agranulocytosis) and extreme hyperleukocytosis, as well as suspicion of acute leukemia, require a rapid diagnostic work-up. A newly detected anemia should not necessarily be treated by packed red cell transfusions. The decision whether an anemic patient ought to receive transfusions should be based on the speed with which the anemia has developed, as well as on clinical judgement. As a rule a chronic anemia patient with hemoglobin above 70 g/l does not need transfusions. An uncritical transfusion policy can even cause emergencies, e.g. in patients with megaloblastic anemia or in anemic multiple myeloma patients with a hyperviscosity syndrome. An elevated hematocrit requires prompt further investigations. This is of utmost importance if one considers the diagnosis of polycythemia vera rubra, a disease in which patients are particularly prone to thrombotic complications. Fragmented red cells (schistocytes) on peripheral blood smears constitute a cardinal diagnostic clue for the detection of microangiopathic hemolytic anemias (MAHA), in particular for the diagnosis of the life-threatening thrombotic thrombocytopenic purpura (TTP) and hemolytic uremic syndrome (HUS). Malaria is another example for a chief role of blood smears examination in achieving a rapid diagnosis. If one encounters an unexpected severe thrombocytopenia, a marrow examination reveals whether it is due to rapid peripheral destruction, or due to a marrow failure. Furthermore, in any patients with an unanticipated thrombocytopenia, a disseminated intravascular coagulation and a MAHA should be ruled out. Heparin-induced thrombocytopenia is a rare, but possibly fatal complication of therapy with heparins.

A 44-year-old Spanish woman travelled in Kenya without doing correct malarial prophylaxis. Upon her return to Spain, she suffered from Plasmodium falciparum malaria. She was initially treated with chloroquine for three days, but her state worsened and she was admitted to our intensive care unit. On admission, parasitaemia was 22%. She had hyperpyrexia, obtundation, hypotension, tachycardia, tachypnoea, jaundice, digestive haemorrhage, petechiae in her soles, oliguria with elevation of serum uraemia and creatinine, anaemia, thrombocytopaenia, hypoproteinaemia, hyponatraemia, hypocalcaemia, metabolic acidosis and parameters of disseminated intravascular coagulation. She was given quinine, sulfadoxine-pyrimethamine and clindamycin. An exchange transfusion was performed, during which an acute pulmonary oedema appeared, initially with high pulmonary artery wedge pressure. She required mechanical ventilation for 16 days and haemodialysis for 11 days. She remained in coma and had seizures which required diazepam, phenitoin and thiopentone. She received a total amount of 22 units of packed erythrocytes, 55 of platelets and 15 of plasma. After the first week, she had nosocomial infection due to Escherichia coli, Staphylococcus and Pseudomonas aeruginosa and was treated with the corresponding antibiotics. She cured completely. This case report gives us the possibility of discussing on frequent problems in the prevention and treatment of malaria, and on the treatment of severe, life-threatening malaria in the setting of the intensive care unit.

An 11-year-old mixed-breed dog was examined because of chronic diarrhea, anorexia, and weight loss. Clinicopathologic abnormalities included anemia and hypoalbuminemia, and protein-losing enteropathy was identified. Acute, unilateral, femoral artery thrombosis developed before the cause of the protein-losing enteropathy could be identified. The dog was treated with aspirin, and sensation and function of the affected limb returned over the next 5 days, but thrombosis of the opposite femoral artery then developed. The dog was euthanatized, and at necropsy, intestinal lymphosarcoma was the only disease process found. Although disseminated intravascular coagulation is a well-recognized potential complication of neoplasia in dogs, recurrent localized thrombosis, as in this dog, also can develop.

An 8-month-old male infant with severe anemia and thrombocytopenia was brought to our hospital due to fever and pallor. The physical examination on admission showed pale conjunctivae, skin rash, lymphadenopathy and hepatosplenomegaly. Subsequent laboratory studies showed pancytopenia, impaired liver function, elevated lactate dehydrogenase level but without evidence of disseminated intravascular coagulation. Bone marrow aspiration demonstrated increased macrophages and prominent hemophagocytosis. The serological studies revealed a recent infection of human herpesvirus-6 which was confirmed by blood mononuclear cell culture and polymerase chain reaction. This infant was also found to have beta-thalassemia which was confirmed by hemoglobin electrophoresis performed before first transfusion. After treatment with intravenous immunoglobulin and other supportive therapies, the bone marrow abnormalities has completely recovered after 5 days, and the hemogram improved. This report demonstrates the human herpesvirus-6 as the etiology of hemophagocytic syndrome.

We report on a 3-day-old newborn with critical coarctation of the aorta, coexisting adrenal and intracranial hemorrhages and acute renal failure requiring dialysis. Severe hypoglycemia, hyperbilirubinemia, mounting anemia and thrombocytopenia, clotting disturbances suggesting DIC, pneumonia, hypertension, increasing circulatory failure and repeated intracranial hemorrhage were observed and were the reason for postponing heart surgery. The child was operated on during the third week of hospitalisation on an emergency basis. The cardiac surgery procedure was performed successfully.

A dog whose major clinical signs suggested a coagulopathy, is described. The dog had a history of bleeding episodes and had a severe regenerative anaemia. By using specific factor assays, the coagulopathy was found to be due to a consumptive intravascular process that resembled chronic disseminated intravascular coagulation. Subsequent investigations identified Angiostrongylus vasorum as the cause.
