A rare case of acute promyelcytic leukemia (APL) is reported in a 7-year-old boy. The patient displayed the typical features of APL including impaction of the marrow with promyelocytes, marked elevation of the serum vitamin B12 and transcobalamin I levels and a hemorrhagic diathesis. The bleeding diathesis in the case was due to thrombocytopenia, and there was no evidence for disseminated intravascular coagulation.

The administration of mithramycin to patients with testicular tumors has been accompanied by a hemorrhagic diasthesis, often in the absence of thrombocytopenia. Bleeding time, platelet aggregation, platelet adenine nucleotide levels, and coagulation factor assays were studied in three patients receiving mithramycin for embryonal testicular carcinomas. These studies demonstrated a drug dependent, reversible hemorrhagic diathesis associated with (1) prolongation of bleeding time, (2) decreased platelet aggregation responses to ADP, collagen, and epinephrine, and (3) depleted platelet stores of ADP in the absence of thrombocytopenia. These abnormalities were temporally correlated with the onset of mucocutaneous bleeding in all patients.

The Kasaach-Merritt syndrome involves the very infrequent symptom complex of "giant hemangioma--thrombocytopenia--coagulation disorder". Hemorrhagic diathesis is here based on consumption coagulopathy. This paper reports upon secondary bleeding after extraction of a tooth in a 25-year-old male affected with this syndrome. Continuation or initiation of anticoagulant therapy is recommended for surgical stomatological treatment on an inpatient basis, and measures to be taken in connection with wound treatment are described.

The clinical and laboratory features of nine patients with chronic myelomonocytic leukemia are described. Hepatic or splenic enlargement accompanied by an absolute monocytosis in an older patient with an elevated serum or urine lysozyme and serum vitamin B12 levels were characteristic of the majority of patients in this series. No single clinical or laboratory finding was diagnostic for the disease. Most importantly, seven of nine patients had abnormal coagulation values; in two cases the abnormalities were consistent with disseminated intravascular coagulation and correlated with a hemorrhagic diathesis. It is concluded that patients with chronic myelomonocytic leukemia who have thrombocytopenia or a bleeding tendency should be evaluated for evidence of disseminated intravascular coagulation.

One hundred and sixty cases of acute leukemia observed at our Department between 1953 and 1977 were reviewed as to the presence and nature of the accompanying gastrointestinal hemorrhage. A massive gastrointestinal hemorrhage requiring blood transfusions occurred in 29 cases (18%). The most common lesion was hemorrhagic necrosis of the small intestines. There were three forms of hemorrhage: Type I: thrombocytopenia, hemorrhagic diathesis, diffuse hemorrhage of mucosa and submucosa, but no erosion nor ulceration. Type II: no specific pathologic findings. Diffuse hemorrhage, superficial erosions, bacterial and fungal invasions were observed. Type III: single and/or multiple ulcerations, necrosis and perforation of the small intestines and colon. Thrombocytosis was almost always present at the prebleeding phase in these cases. Intravascular microthrombi at the basis of ulceration were seen. Usually, more than one process were seen in each case. An appropriate approach to the severe gastrointestinal hemorrhage with a combination of anti-leukemic chemotherapy, anti-coagulant therapy, platelet transfusion, etc. would further add to the number of long-term survivors in acute leukemia.

The haemolytic uraemic syndrome is an acute illness characterised by the occurrence of renal injury, haemolytic anaemia with red cell fragmentation and thrombocytopenia. Haemorrhagic diathesis, arterial hypertension and neurological manifestations often complicate the acute phase of the disease. In this article, we shall discuss in more detail the aspects of this phase. Data obtained in 72 patients treated at the Wilhelmina Children's Hospital in Utrecht, from 1964 to 1977, are used to illustrate the characteristics of the disease.

The platelet function was studied in 23 patients with systemic lupus erythematosus, all of whom met the diagnostic creteria established by the American Rheumatism Association. They were not under any treatment, especially with any drug that might interfere with platelet function. The same study was performed on a control group composed of volunteers donors at a blood bank. The platelet count was definitely lower in the patients with lupus than in the control subjects (p less than 0.0005), although a clear thrombopenia was observed in only two indivduals (8.7 percent). Anti-platelet antibodies were found in only six cases (26 percent). There was a linear correlation between thrombopenia and the presence of hemorrhagic diathesis and low levels of C4 and CH50 components. Plateler adhesiveness was clearly lower in the lupus group than in the control group (p less than 0.0005). The presence of kidney disease determined a greater impairment of the platelet adhesiveness (p less than 0.0025). A notable defect on platelet aggregation was induced by ADP, adrenaline and collagen. This was more apparent in the group of patients exhibiting a higher degree of clinical activity and in those who showed a serum complement decrease. The mechanism responsible for this thrombopathy appears to be an interference in the platelet function due to the presence of circulating immunocomplexes. They adhere to the platelet membrane blocking its function and inhibiting the release of the necessary thrombocytic components for the second phase of the aggregation. This platelet alteration is not usually manifested clinically; for this reason no relationship was found between this platelet defect and the presence of hemorrhagic symptoms in our patients. The condition is reversible and may disappear after therapy with steroids and/or immunosuppresive agents.

We describe a microtechnology for the study of the coagulation system in newborn infants. Interpretation of results demands an understanding of the techniques used and the nature of the control population from which normal values are drawn. We have examined two syndromes which represent the majority of hemostatic disorders of sick newborn infants. The first is thrombocytopenia resulting from bacterial infections in which there are minimal changes in the levels of blood coagulation factors and little tendency to bleed. The second is a syndrome of disseminated intravascular coagulation in which there is a profound disturbance in the coagulation mechanism, relatively little change in platelet counts, a severe hemorrhagic diathesis, and widespread ischemic necrosis.

An outbreak of chronic liver disease was investigated in a kennel of dogs. Anorexia, depression, polyuria, polydipsia, icterus and a terminal hemorrhagic diathesis were noted in clinically affected dogs. Thrombocytopenia, hypofibrinogenemia, elevated fibrinogen degradation products and prolonged activated partial thrombosplastin times (PTT) and one-stage prothrombin times (PT) were associated with the hemorrhagic crisis. Aflatoxicosis was confirmed by the presence of significant levels of aflatoxicosis was confirmed by the presence of significant levels of aflatoxin B in the commercial dog food being fed. A subacute hepatitis was found on necropsy. Disseminated intravascular coagulation was suspected as the cause of the hemorrhage in these cases and treatment was instituted.

Dapsone was given for six days to a dog with chronic skin disease. The dog then became weak and anorectic, and it vomited and had purpura caused by severe thrombocytopenic hemorrhagic diathesis. Despite treatment, the dog died a week later. There were clinical and pathologic evidence that the dog's platelets and megakaryocytes had been destroyed during the first few days of dapsone therapy. It was concluded that the syndrome was dapsone-induced and that thrombocytopenia should be considered among the adverse reactions to dapsone in the dog.
