A case of neonatal nonbacterial thrombotic endocarditis confirmed at autopsy was identified in the neonatal intensive care unit. The infant suffered from hyaline membrane and disseminated intravascular coagulation. A degenerative verrucal endocarditis at the tricuspid and aortic valves was demonstrated in addition to pulmonary and renal embolism. Vegetations on the heart valves of the newborn infants are rare at necropsy and yet to be diagnosed antemortem. Prospective studies are needed to determine whether high-risk patients should be screened periodically by echocardiographic technique.

Aspergillus fumigatus endocarditis developed in a 2 1/2-year-old girl after repair of tetralogy of Fallot. There have been 14 other cases of Aspergillus endocarditis in children described in the literature. Fever and embolic phenomenon, particularly to the CNS, were the most common presenting manifestations. Consumptive coagulopathy developed in this patient as it has in other children and should suggest the diagnosis of Aspergillus endocarditis inasmuch as blood cultures are uniformly negative. Antemortem diagnosis was made in four of 15 patients. Only one patient survived the infection. Environmental surveillance is crucial when a case is encountered. Survival of the infected patient occurs only with early diagnosis and surgical removal of the infected tissue.

Of 13,913 patients examined at autopsy between 1939 and 1980, the diagnosis of nonbacterial thrombotic endocarditis (NBTE) was made in 99 instances. There were 53 males and 46 females ranging in age from 4 to 89 years. Vegetations were found on the aortic valve in 39; the mitral in 37; the tricuspid in nine; and the mitral in 37; the tricuspid in nine; and the pulmonic in two. Two-valve involvement was present in 12 cases. Malignant neoplasms were found in 42 autopsies. Embolism to the brain was found in 33 cases and to other organs in 62. Coagulation abnormalities were documented in 22 cases, and a distinct picture of disseminated intravascular coagulation of thrombophlebitis elsewhere in the body should arouse suspicion of NBTE. The high incidence of multiple emboli and its association with malignant neoplasms and with a variety of cardiovascular, pulmonary, renal, and gastrointestinal disorders should provide clues for recognition of this serious disorder.

Sixty-five patients with a bleeding disorder and coexistent neurologic abnormalities were examined over a 4-year period to determine: (1) the CNS pathology due to disseminated intravascular coagulation (DIC); (2) the clinical setting in which CNS dysfunction due to DIC occurs; and (3) the neurologic complications of DIC as opposed to those patients dying with concurrent DIC. Criteria for inclusion in the study were the combination of: (1) a neurologic disorder in a patient with clinical evidence of a bleeding disorder; and (2) evidence of DIC by laboratory criteria or the detection of fibrin thrombi in multiple organs at postmortem. Twenty-four of 65 patients met these diagnostic criteria, including 14 men and 10 women, aged 24 to 84 years. Autopsies were obtained in 17 patients. These patients were divided into two groups Group I consisted of 10 patients with evidence of cerebral bleeding or infarction at the onset of DIC. Group II consisted of 14 patients who met the diagnostic criteria for DIC but did not demonstrate postmortem evidence of hemorrhage or infarction in the brain. Patients with malignancy who present with findings suggestive of a large-vessel stroke are likely to have DIC and nonbacterial thrombotic endocarditis. The most common neurologic complications of DIC are large vessel occlusion, obtundation and coma, subarachnoid hemorrhage, and multiple cortical and brainstem hemorrhages and infarction.

Three cases of adenocarcinoma that were complicated by nonbacterial thrombotic endocarditis and disseminated intravascular coagulation are described. In two of these cases mucin was demonstrable within vascular channels as well as within the thrombotic vegetations of the cardiac valves. This intravascular mucin was also responsible for vascular occlusion with resultant infarction in such organs as heart and brain. Intravascular mucin of this magnitude has not been previously recorded and mucinous accumulations behaving as thromboemboli with infarcts have not been heretofore described.

During the course of 6 000 autopsies, the number of cases of non-bacterial thrombotic endocarditis discovered was 130 (absolute frequency of 2.1 p. cent). Frequency was highest among patients with cancer, of which there were many in this series (4 p. cent of 2 287 autopsies). In 83 p. cent of cases, therefore, the endocarditis was of paraneoplasic origin, usually associated with adenocarcinomas, especially those of bronchopulmonary, pancreatic or gastric origin. Less frequently, they developed during the course of shock or debilitating affections. The endocarditis lesion consists of a coagulated fibrin and platelet mass without microbial germs, located electively on the mitral and aortal valves. Emboli are a frequent consequence (47 p. cent of cases) affecting primarily the central nervous system, the kidneys, spleen, and hart. Ischemic effects of these latter, observed in 75 p. cent of cases, are generally latent. In some cases they produce clinical manifestations, and they may be the cause of death from a cerebral or myocardial infarct. Pathological examination demonstrates the frequent association of these endocarditis lesions with often multiple vascular thromboses, and disseminated intravascular coagulation affecting the same regions as the emboli. This emphasizes the major role of coagulation disorders in their genesis.

Patients infected with the human immunodeficiency virus (HIV) appear to have a high risk of ischaemic cerebral events. We observed two cases of cerebral infarction in patients with acquired immune deficiency syndrome (AIDS). In the first case, a 38-year-old homosexual with no cardiovascular risk other than smoking presented with rapidly progressive hemiparesia. Brain CT-scan visualized two infarcts in the territory of the right sylvian artery and the arteriography an occlusion of the internal carotid artery. In the second, a 37-year-old homosexual, hospitalization was required for a left-sided pure sensitive epilepsy seizure. There was no cardiovascular risk other than smoking. Magnetic resonance imaging showed parietal ischaemia and thrombus in the left atrium without atrial hypertrophy was seen at transoesophageal echocardiography. In both cases, there was no evidence of endocarditis, dissection of the neck vessels or disseminated intravascular coagulation nor of associated viral or bacterial infectious complication of AIDS. Angiographic findings eliminated cerebral vascularitis. Among the perturbed haemostasis factors previously reported in HIV+ patients, we observed free proteins S deficiency (68 and 43%) and heparin cofactor II deficiency (54 and 40%). Serum albumin was 33 and 32 g/l respectively. Outcome was favourable in both cases with anticoagulant therapy. These coagulation anomalies would not appear sufficient to explain cerebral infarction. Other mechanisms including immune complexed deposition, direct HIV toxicity for endothelial cells or the effect of cytokines on smooth muscles fibres and fibroblasts are probably more important causal factors.

Twenty-five patients were admitted to two hospitals in Hong Kong for Streptococcus suis infection between 1984 and 1993. Among them, 15 (60%) had an occupational exposure to pigs or pork, and four had a clear history of skin injury up to 16 days before admission. Examination of the cerebrospinal fluid of 21 patients confirmed the presence of meningitis in every case; the remaining four patients who did not have lumbar punctures had each presented with arthritis, bronchopneumonia, endocarditis and pyrexia without neck stiffness. The only fatality was a patient admitted in septicaemic shock with evidence of meningitis and disseminated intravascular coagulation. Of the 24 survivors, 16 (67%) acquired varying degrees of hearing loss as a result of meningitic involvement. All the isolates of S. suis were sensitive to penicillin or ampicillin, which was used alone or in combination with other antibiotics for every patient. Two patients had a relapse of symptoms when penicillin was stopped, but were successfully treated after the antibiotic was resumed for a total of 6 weeks. Over 100 cases of S. suis infection have been described previously, with a geographic distribution heavily biased towards Northern Europe and Southeast Asia. Lack of awareness of this unique zoonosis may be a reason why it is not diagnosed more readily elsewhere.

We report a patient of ventricular septal defect associated with a vegetations on the tricuspid valve and a perforation of the aortic cusp caused by infective endocarditis. Antibiotics could not relieve the high fever of this patient, and disseminated intravascular coagulation caused by sepsis and two-sided heart failure developed. She underwent extended tricuspid valve excision, aortic valve replacement and VSD closure during the active stage. Post-operative antibiotic therapy was continued intravenously for 6 weeks, and orally for 3 more weeks. Although post-operative right ventriculography indicated tricuspid regurgitation and right atrium enlargement, pressure study of the right side of the heart revealed normal hemodynamics.

Thirty-nine Danish cases of Capnocytophaga canimorsus septicemia were reviewed to determine the clinical course of this infection. The cases of septicemia were related to recent dog bites or other close contact with dogs. The period from the bite to the onset of symptoms ranged from 1 to 8 days. The mean age of the patients was 59.1 years (range, 28-83 years). Underlying conditions included previous splenectomy and alcoholism. Thirteen patients had previously been in good health. Common initial symptoms were fever, malaise, myalgia, vomiting, diarrhea, abdominal pain, dyspnea, confusion, headache and skin manifestations. Disseminated intravascular coagulation developed in 14 patients, meningitis in 5, and endocarditis in 1. Twelve of the patients died. All patients except two were treated with penicillin or ampicillin. Five patients had received antibiotics prior to admission. Attention should be drawn to C. canimorsus septicemia in cases of febrile illness following dog bites or contact with dogs, as well as those involving previously healthy persons. The incidence of this condition in Denmark is estimated to be 0.5 case per 1 million people per year.
