Analysis of 182 patients with chronic disseminated intravascular coagulopathy and malignancy shows common features. Migratory thrombophlebitis occurred in 96 patients while at least a single episode of thrombophlebitis was noted in 113. Seventy-five of the patients bled and 45 had arterial emboli in various organs. Twelve patients had the triad of thrombophlebitis, hemorrhage, and arterial emboli, often sequentially. Hematologic data showed derangements associated with intravascular coagulation, the most prominent of which were hypofibrinogenemia and thrombocytopenia. Other abnormalities included prolonged prothrombin time, increased fibrinogen-fibrin degradation products, decreased levels of factors V and
VIII
, cryofibrinogenemia, and microangiopathic hemolytic anemia. Forty-one patients had lesions of non-bacterial thrombotic
endocarditis
at autopsy; 31 of these had arterial emboli during life. None of the lesions were infected. Mitral and aortic valves were most frequently involved. No single mechanism that causes the disseminated intravascular coagulopathy has been identified. However, cell products--secretions and enzymes--and the cells themselves have been proposed as the procoagulant(s) responsible for the syndrome. In addition to treatment of the underlying neoplasm, symptomatic disseminated intravascular coagulopathy should be controlled. Heparin is the drug of choice for treatment of this problem, very little benefit having been observed with warfarin therapy. Long-term use of anticoagulants is potentially feasible for control of chronic disseminated intravascular coagulopathy, but without effective control of the underlying tumor ultimately will be unsuccessful.

Endothelial cells were prepared from rat heart, and the ability of various bacterial species to adhere to these cells was investigated, with special regard to alpha-hemolytic streptococci. The endothelial cells were identified by morphology and by the presence of F
VIII
antigen. Seventeen bacterial strains representing various species were used in the in vitro adherence tests; 10 strains represented various strains of alpha-hemolytic streptococci, 5 of which were isolated from patients with infective
endocarditis
and 5 from the throats of healthy individuals; 2 were Neisseria meningitidis, 2 N. gonorrhoeae, 2 S. aureus and 1 E. coli. The highest adherence rate was found for alpha-hemolytic streptococci isolated from patients with infective
endocarditis
. The difference compared to carrier strains of alpha-hemolytic streptococci and to the other tested strains was statistically highly significant.

Clinico-pathological data in a typical case are compared with those of 54 published reports of systemic angioendotheliomatosis. In this rare disease the lesions, characterized by clusters of abnormal cells in the small vessels, usually have multivisceral localizations, with chiefly cutaneous and encephalic manifestations and a rapidly fatal course. However cases are known with lesions restricted to the skin and a protracted if not regressive course; about half of these cases are associated with an
endocarditis
. In the case reported, the results of ultrastructural and histo-immunological studies (f.
VIII
, lysozyme, anti-protease, Ig) are in favour of the endothelial origin of the abnormal cells, a now widely accepted hypothesis.

This paper reports a case of Haemophilus segnis polymicrobial bacteraemia and a case of H. segnis monomicrobial bacteraemia identified by 16S ribosomal RNA gene sequencing. In the first case, a gram-negative aerobic coccobacillus was isolated with Streptococcus intermedius and S. sanguis from the blood culture of a 32-year-old intravenous drug addict with left thoracic empyema. In the second case, a gram-negative aerobic coccobacillus was isolated from the blood culture of an 82-year-old woman with Clostridium difficile colitis and septicaemic shock. Both gram-negative coccobacilli grew on chocolate agar as colonies of 1 mm in diameter after incubation for 24 h at 37 degress C in air with CO2 5%, but only to pinpoint sizes on blood agar under the same incubation conditions. Both strains were factor V-dependent, but not factor X-dependent. For the first isolate, the Vitek system (NHI) showed that it was 56% likely to be Actinobacillus actinomycetemcomitans and 40% Neisseria subflava; whereas the API system (NH) showed that it was 58% likely to be H. aphrophilus/paraphrophilus and 42% H. parainfluenzae. For the second isolate, the Vitek system (NHI) showed that it was 95% likely to be H. influenzae
VIII
; whereas the API system (NH) showed that it was 58% likely to be H. aphrophilus/paraphrophilus and 42% H. parainfluenzae. 16S rRNA gene sequencing showed that there were four base differences between isolate 1 and H. segnis and two base differences between isolate 2 and H. segnis, indicating that both isolates most closely resembled a strain of H. segnis. Only two cases of H. segnis bacteraemia were found in the English scientific literature, one in a case of infective
endocarditis
and the other in a case of pancreatic abscess. Including the present two cases, the overall mortality of H. segnis bacteraemia was 50%.
