Three cases of malignant histiocytosis occurring in children aged 2 months, 10 months and 14 years, are described. In all children the diagnosis was based on anaemia, granulocytopenia or thrombocytopenia, splenomegaly and marked erythrophagocytosis by bone marrow and lymph node atypical histiocytes. Two children aged 10 months and 14 years, underwent splenectomy after which combined chemotherapy with cyclophosphamide, vincristine and prednisone (COP) was started. In the older child a complete remission was achieved. The younger child died soon after the onset of the treatment. The youngest child was treated with bleomycin, adriamycin, cyclophosphamide, vincristine and prednisone (BACOP). He died of pneumonia and sepsis two months after the start of the treatment.

Thirty-nine patients with advanced epidermoid carcinoma of the head and neck were treated with a combination of cis-dichlorodiammineplatinum(II), methotrexate, bleomycin, and vincristine. Twenty-nine patients were evaluable for response and 39 were evaluable for toxicity. With this regimen toxicity was acceptable and the following rates were observed in a total of 139 treatment courses: 100% (nausea and vomiting), 3% (decreased creatinine clearance), 4% (thrombocytopenia), 5% (leukopenia), and 2% (pulmonary fibrosis). There was one death due to sepsis during a period of chemotherapy-induced leukopenia. Although the patients treated with this regimen had advanced disease and had been treated aggressively previously, an overall response rate of 24% was observed, with three patients (10%) having a complete response. Median duration of response was 7 + months. These results indicate that this intensive combination chemotherapy has a sufficiently favorable risk/benefit ratio to allow its evaluation in randomized clinical trials in patients with head and neck cancer.

Review of the coagulation laboratory records and medical records at Memorial Sloan-Kettering Cancer Center over a three year period (1971--1974) revealed 89 patients with disseminated intravascular coagulation (DIC). The diagnosis of DIC was made if laboratory studies showed evidence of quantitative and qualitative changes in fibrinogen and significant thrombocytopenia. The patients included 19 with leukemia (17 acute), 3 with multiple myeloma, 15 with lymphoma, 46 with metastatic solid tumors, (10 lung, 9 breast, 8 gastrointestinal, 12 genitourinary, 7 miscellaneous) 4 with vascular tumors, and 3 without tumor. Other conditions which might have precipitated or initiated DIC such as gram-negative sepsis, liver impairment, or mucin secreting tumors were present in the majority of patients. Bleeding occurred in 75% of the patients and was fatal in 36%. Thromboembolism occurred in 22.5%. Thirteen percent were asymptomatic. Serum lactic dehydrogenase was elevated in over 75% of the patients at the time of, or subsequent to the occurrence of DIC. Treatment with heparin was helpful in only three of twenty patients. Eighty percent of the patients died within one to over 30 days of the onset of DIC. Post mortem evidence of DIC was present in 18 of 43 autopsies. Results of this study indicate that DIC is a frequent complication of a wide variety of tumors and that its occurrence causes morbidity and mortality in a significant number of patients. Treatment with heparin is of little help unless remission is induced and the precipitating factor(s) are reversed.

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.

The unexplained occurrence of thrombocytopenia in cases of Gramnegative sepsis in man led us, in the light of animal experiments indicating the blood platelet as the target cell for endotoxin, to examine the effect of Salmonella enteritidis lipopolysaccharide B on human platelets. Human platelets were separated from a coat of plasma proteins by Sepharose 2B filtration or by a combined procedure of albumin gradient and Sepharose 2B filtration. The action of endotoxin on human platelets resulted in membrane changes manifested by dose-dependent release of [3H]serotonin and adenine nucleotides. Cytoplasmic marker, lactic dehydrogenase, and lysosomal marker, beta glucuronidase, were retained indicating that the release reaction was selective. Release of [3H]serotonin was specific for endotoxin since other particulates, zymosan and erythrocyte stroma, were without effect. Endotoxin, added to gel-filtered human platelets, induced a significant evolution of platelet factor 3 procoagulant activity. Preincubation of endotoxin with a membrane-rich homogenate of human platelets inhibited its labilizing effect on human platelets thus suggesting an interaction between endotoxin and the platelet membrane itself. Other plausible factors in this interaction [fibrinogen, adenine nucleotides, thrombin, sialic acid residues, and IgG] were eliminated on the basis of a series of control experiments. From the negligible effect of aspirin and indomethacin, we may infer that the interaction of endotoxin with platelets does not depend on the platelet prostaglandin synthesis pathway. The direct interaction of endotoxin with the human platelet membrane comprises a new mechanism which may help to clarify the pathogenesis of vascular and haemostatic disorders accompanying bloodstream infections due to Gram-negative bacteria.

DDMP, a diaminopyrimidine folate antagonist, was given to 26 tumor patients in a dosage of 50 mg/m2 per week orally, simultaneously with 3 mg CF i.m. or i.v. The CF dose was increased to 30 mg in patients showing evidence of toxicity, and withdrawn in the absence of toxicity. The dose-limiting toxicity was seen in myelosuppression, particularly thrombopenia and skin rashes. At the 3 mg CF level, 18 out of 26 patients developed toxicity. No toxicity was seen at the 30 mg CF level in 11 patients. After cessation of CF, toxicity occurred in five out of seven patients. After the onset of toxicity, CF was added as a delayed rescue, in a dosage of 15 mg every 8 h or 30-60 mg daily. One patient died of sepsis with agranulocytosis. All other patients recovered from myelosuppression within 1 or 2 weeks. Objective responses were observed in seven patients, four of the ten with epidermoid cancer of the head and neck, two out of eight with epidermoid cancer of the lung, and one out of three with melanoma.

The clinical records of 180 pediatric patients who received Intralipid via peripheral veins at a single institution (1964-1977) were retrospectively analyzed, with particular reference to the complications of this form of therapy. Intralipid was used in a dose range of 2--4 g/kg/day in order to supply 40% of the daily calorie requirements. The patients were neonates, infants, children, and adolescents with a wide range of clinical diagnoses. Local complications associated with Intralipid therapy were minimal. Transient elevations in serum enzyme levels (SGOT, SGPT, and LDH) were observed in 4% of patients, but all of these returned to the normal range after cessation of therapy. Ten patients had histologic evidence of cholestasis, the significance of which is discussed. The lipid emulsion was employed in patients with preexisting hyperbilirubinemia with concomitant resolution of jaundice. Intralipid was administered to patients with known severe thrombocytopenia (secondary to sepsis or myelosuppression) with return of the platelet counts to normal levels during the course of infusion therapy. The use of Intralipid in patients with established sepsis did not delay its response to conventional surgical or antibiotic therapy. There were no instances of the "overloading" syndrome observed.

Consecutive newborn autopsy cases were divided into infected and noninfected groups on the basis of pathologic findings and cultures, and were compared to a concomitant consecutive group of neonatal survivors with proven bacterial sepsis. Newborns dying with bacterial infection often demonstrated leukopenia, neutropenia, and thrombocytopenia, usually associated with normal bone marrow cell production. Those with nonfatal sepsis frequently had neutrophilia with an increase in absolute band counts. Of infected newborns 80% showed one or more hematologic abnormalities as did 43% of newborns dying without bacterial infection. Of newborns dying with bacterial infection 13% had no hematologic abnormality. Blood cultures were negative in 18% (seven) of the infants dying with bacterial infection. Abnormalities of the white blood cell, differential and platelet counts are not invariably specific for bacterial infection nor do normal values adequately exclude it. Blood cultures may be negative in newborns dying with significant foci of bacterial infection.

Thirteen patients with significant hemorrhage, severe thrombocytopenia, and megaloblastic bone marrows are described. Unusual features of this problem included its acute onset, frequent absence of the typical peripheral blood changes of megaloblastic anemia, normal serum B12 levels, and serum folates which were often not clearly abnormal. Most patients were critically ill and common clinical features included reduced dietary intake, renal failure, renal dialysis, the postoperative state, and sepsis. These clinical features, the laboratory findings, and a platelet increase in most patients after folate therapy lead to the conclusion that this problem is probably due to acute folic acid deficiency. Possible explanations for the atypical laboratory findings include the acuteness of onset, recent blood transfusion therapy, and impaired folate utilization. This problem may be relatively common. Because of its potential clinical importance, rapid onset, and attendent diagnostic difficulties, prophylactic folic acid is recommended in the clinical setting described.
