In a retrospective study 40 children were selected out of 53 cases of septicaemia with thrombocytopenia. They were divided into two coincidentally equally large groups of patients with consumption coagulopathy on the one side and patients with isolated thrombocytopenia without consumption coagulopathy on the other side. Both groups were of comparable age and sex distribution. Two-thirds of the children were under three months. For the differential diagnosis of both groups the activated partial thromboplastin time, the thrombotest, the factor V plasma concentration, the serum concentration of fibrin (fibrinogen) degradation products as well as control coagulation studies can be considered to have the greatest diagnostic value. The results of the study permit the following conclusions: 1. Platelet deficiency in sepsis does not prove the presence of consumption coagulopathy. 2. Consumption coagulopathy and isolated thrombocytopenia differ statistically significantly according to the bacteria cultured from the blood, the circulatory state and the pH of the blood. 3. The finding of thrombocytopenia in a patient with shock, acidosis and gramnegative septicaemia justify the suspicion of consumption coagulopathy.

Two patients developed heat stroke following jogging. Transient disturbance of cerebral function was the most dramatic clinical feature. Although haemorrhagic complications were not seen, marked changes in the haemostatic system occurred with both thrombocytopenia and a reduction of clotting factors synthesised by the liver. No evidence of disseminated intravascular coagulation was found. Heat stroke must now be added to the list of jogging hazards.

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.

Sixteen cases of neonatal cold injury, five of them fatal, were seen in the winter of 1974-75. The affected infants, who weighed from 2.5 to 3 kg. had developed symptoms when the ambient termperature was below 10 C. Few of them were referred as cases of hypothermia. Refusal to eat was the most common complaint and less often edema and/or apathy. No correlation was found between death and ethnic origin, sex, duration of illness or minimum temperature. Admission weight, however, tended to be lower in the infants who died. The consistent finding of thrombocytopenia and the suspected bleeding phenomena suggested that disseminated intravascular coagulation may have been a factor in the unfavorable outcome of some of the cases. Evidence supporting such a hypothesis and proposals for the prevention. Diagnosis and treatment of neonatal cold injury are presented.

Coagulation studies were done on 78 consecutive cases of obstructive jaundice with or without biliary tract infection. Among 26 cases with biliary tract infection 20 cases showed no bleeding tendency but remarkable hypercoagulability with decreased fibrinolytic activity. Other six cases developed diffuse bleeding tendency in addition to the signs of hypotension and multiorgan dysfunction such as oliguria, respiratory distress and mental confusion. Most showed marked coagulation defects characterized by thrombocytopenia, decreased fibrinogen, antithrombin III and plasminogen levels and narrowing of maximal amplitude in thrombelastogram as well as the increase of fibrin degradation products and positive soluble fibrin monomer complexes. All except one died and three cases were autopsied. In two cases postmortem examination revealed multiple fibrin thrombi in lungs and other organs. A cause of the development of bleeding tendency in obstructive jaundice presently observed may likely to be due to the occurrence of disseminated intravascular coagulation (DIC), i.e. hypercoagulability caused by the biliary tract infection is responsible.

Acute promyelocytic leukemia is a form of acute myeloblastic leukemia characterized by hemorrhagic episodes, severe thrombocytopenia and infiltration of the marrow with "hypergranular" promyelocytes, often with multiple Auer bodies. Ultrastructurally. the promyelocytes show many splinter granules and Auer bodies with characteristic hexagonal arrangement of tubules with a periodicity of 250 A. Serum vitamin B12 and B12-binding proteins, in particular, transcobalamin I, are abnormally high. Karyotypic abnormalities include pseudodiploidy and partial deletion of the long arm of chromosome 17. Coagulation profile during bleeding episodes is usually consistent with disseminated intravascular coagulation. Greatly improved prognosis in recent years as a result of aggressive chemotherapy and anticoagulation emphasizes the need of early recognition of this clinical entity.

Four cases of hepatic angiosarcoma are reported with a review of 99 other cases in the English literature. Angiosarcoma of the liver is associated with chronic exposure to thorotrast, vinyl chloride, arsenicals, radium and possibly copper and with chronic idiopathic hemochromatosis. Although 40% of patients have hepatic fibrosis or cirrhosis at autopsy, the nature of the association between chronic liver disease and hepatic angiosarcoma is unknown. The clinical presentation of hepatic angiosarcoma is nonspecific with abdominal pain, weakness and weight loss common complaints and with hepatomegaly, ascites and jaundice common findings. Liver function tests are usually abnormal but there is no one liver function test or set of tests specific for the tumor. The occurrence of thrombocytopenia and disseminated intravascular coagulation is characteristic of hepatic angiosarcoma and may be related to local consumption of clotting factors and formed blood elements in the tumor. Catastrophic intraabdominal bleeding is also characteristic and occurs in one-fourth of all cases. This complication is likely related to the high incidence of clotting abnormalities and the vascular nature of the neoplasm. Selective hepatic arteriogram and open liver biopsy are the foundations of diagnostic evaluation. Percutaneous liver biopsy should be avoided. Failure to appreciate the possibility of hepatic angiosarcoma in the proper clinical setting, leading to blind percutaneous biopsy, may result in failure to make the diagnosis at the cost of significant morbidity and mortality. Survival of patients with hepatic angiosarcoma is brief; only 3% live longer than 2 years. Treatment of the tumor to date is empirical. There are probably a few patients who might benefit from radical surgery with curative intent. For all others chemotherapy is indicated. Adriamycin is active against hepatic angiosarcoma, but optimal dose and mode of administration require further investigation. Further study is also required to delineate the cause of hepatic angiosarcoma in the 60% of cases without definite epidemiologic association.

Three cases of postpartum hemolytic uremic syndrome (HUS) are presented. Symptoms of acute renal failure, hypertension and microangiopathic hemolytic anemia with thrombocytopenia occurred 10, 17 and 24 days after delivery. Despite early heparin therapy in all cases, one patient went into terminal renal failure needing chronic hemodialysis, with persistent hypertension which became uncontrollable requiring bilateral nephrectomy 6 months later. The second patient had diuresis one month after starting hemodialysis, but 3 months later developed malignant hypertension. Slight improvement in renal function with persistent hypertension occurred after hemodialysis for 20 months. The third patient showed complete clinical recovery after 2 months. Pathological examination of renal tissue showed the typical lesions of thrombotic microangiopathy (TMA). However, striking differences were observed in the lesion seen in early and late specimens. Early lesions could be differenciated from infancy TMA because the medium-dize arteries were more severely involved. Late lesions were variable, ranging from minor changes in glomeruli and blood vessels, via ischemic and sclerotic lesions in glomeruli with arteriolosclerosis, to the vascular and glomerular lesions seen in malignant nephrosclerosis. There was a good correlation between the renal pathology and the clinical outcome of the patients. HUS with renal TMA as a cuase of postpartum renal failure has been reported in 49 patients with a fatal outcome in 61%. The pathogenesis of the syndrome probably involves a primary endothelial damage. This causes local renal intravascular coagulation in the presence of the usual postpartum hypercoagulable state. This is shown by the presence of fibrin-fibrinogen in glomeruli and vessels, increased plasma fibrin degradation products, thrombocytopenia and lowered levels of coagulation factors. There is little hematological or pathological evidence fo disseminated intravascular coagulation or an immune-complex disease. Hypocomplementemia seen frequently is probably due to local C3 activation via the alternative pathway.

Anticoagulants in the form of heparin, dipyridimole, steroids, prostaglandin E1, Macrodex, and antithrombin III were administered in separate experiments prior to endotoxin infusion in the dog. The pattern of disseminated intravascular coagulation (DIC) developed consistently when endotoxin alone was administered. Heparin dosages from 1 to 10 mg/kg did not influence the appearance of thrombocytopenia but effectively eliminated the decrease in fibrinogen levels ordinarily found. Antithrombin III (AT III), obtained from the National Red Cross, administered in a dose designed to provide a doubling of the circulating AT III, reduced the fibrinogen utilization to a similar degree as heparin without affecting the platelet loss. Dipyridimole, as administered, was ineffective in this model, and did not alter the development of thrombocytopenia or the hypofibrinogenemia. Steroids, Macrodex, and prostaglandin E1 had minimal effect on the coagulopathy. Our finding would suggest that the endotoxin effect on dog platelets id direct, and not mediated by thrombin, and that the role of heparin in the clinical management of DIC should be considered only in instances in which renal complications exist.

An analysis of seven sporadic cases of Legionnaires' disease confirmed clinical features recorded during epidemics and identified aspects of the illness either unreported or not emphasized. Four patients had central nervous system abnormalities. Mental status changes included somnolence, obtundation, delirium, disorientation, and confusion. Three patients experienced visual hallucinations, and one patient without pneumonia had a grand mal seizure with residual memory deficit. Two patients had disseminated intravascular coagulation with thrombocytopenia, elevated split fibrin products, and prolonged partial thromboplastin and prothrombin times. Four patients had severe hypoxia; one patient had an exudative pleuritis. One patient whose treatment included erythromycin had radiologic improvement of his pneumonia despite deteriorating ventilatory function that led to death. The concept of Legionnaires' disease as a severe, diagnostically perplexing pneumonic illness is valid but too narrow. The emerging spectrum is that of a multisystem disease that, besides the lungs, often involves the central nervous system and can be accompanied by disseminated intravascular coagulation.
