A review of the literature reveals only one case of neonatal Escherichia coli pericarditis. This is a case report of Escherichia coli pericarditis occurring in a two day old infant. The infant initially presented with lethargy and jaundice but this rapidly progressed into shock. Despite vigorous resuscitative efforts, the infant succumbed and at autopsy 30 cc of purulent fluid were obtained. Cultures of the admission blood and post-mortem pericardial effusion grew Escherichia coli. The clinical diagnosis of pericarditis is often difficult because of vague, nonspecific symptoms and signs. The symptoms are usually those of sepsis plus those of impaired circulation due to mechanical embarrassment by accumulating pericardial effusion. It is difficult to differentiate pericarditis with effusion from myocarditis and pericardial effusion secondary to congestive heart failure. The use of pericardiocentesis as a diagnostic tool and echocardiography are the most helpful techniques presently available for diagnosis. Management consists of vigorous supportive efforts, antibiotics, and drainage of the pericardial effusion. Because of the very high mortality associated with this disorder, a high index of suspicion with a vigorous diagnostic and therapeutic approach to the patient is indicated.

Diagnostic separation of infants with signs of cardiac failure (hypoglycemia, sepsis, myocarditis, hypoxemia) but no congenital cardiocirculatory malformation from those with a large left to right shunt is crucial in newborn management. Echocardiographic studies of 218 infants and children allowed group separation and distinction from normal by the assessment of mean velocity of circumferential fiber shortening (Vcf) and the ratio of left atrial to aortic root diameter at end-systole (LA/Ao). In normal premature and full-term infants, Vcf (1.51 +/- 0.04 [mean +/- standard error]) was significantly lower than in infants with a large shunt (2.12 +/- 0.08, P less than 0.01) and higher than in infants with nonstructural heart disease (1.18 +/- 0.06, P less than 0.001). LA/Ao ratios were comparable in the groups with a large shunt and nonstructural heart disease (1.14 +/- 0.1 and 1.26 +/- 0.2, respectively) and were significantly higher in both groups than in normal subjects (0.77 +/- 0.01, P less than 0.001). Similar echocardiographic distinctions could be made when 10 older children (aged 2 to 10 years) with cardiomyopathy were compared with 45 normal older children. Serial determination of these variables was of major assistance in patient management.

Renal cortical necrosis, renal medullary necrosis, and combined renal cortical-medullary necrosis result from renal ischemia without vascular occlusion. Renal hypoperfusion and ischemic injury in infants have been ascribed to massive blood loss, hemolytic disease, septicemia, and severe hypoxemia. In a postmortem study we identified 82 cases among 1,638 autopsies during the 20 years between 1970 and 1989 in infants 3 months old or less at the time of death. The frequency of renal necrosis in autopsy cases increased significantly during the last 6 years of the study. The distribution of the renal lesion was cortical in 28, medullary in 23, and combined in 31. Forty infants carried diagnoses of congenital heart disease, 17 of asphyxial shock, 9 of sepsis, 3 of infectious myocarditis, 9 of major malformations, 4 of anemic shock, 1 of vascular malformation, and 1 of gastroenteritis and dehydration. A significantly higher proportion of babies with congenital heart disease had cortical involvement. Comparison of clinical characteristics revealed a significantly higher frequency of prematurity, respiratory distress syndrome, bleeding diathesis, and possibly sepsis in the children with congenital heart disease, suggesting that these factors are important in the pathogenesis of the renal lesion. Fourteen infants underwent cardiac catheterization; there was no demonstrable association between the renal lesions and the use of radiographic contrast medium. We conclude that severe congenital heart disease itself is a risk factor for life-threatening renal cortical and medullary necrosis.

The enteroviruses comprise nearly 70 human pathogens responsible for a wide array of diseases including poliomyelitis, meningitis, myocarditis, and neonatal sepsis. Current diagnostic tests for the enteroviruses are limited in their use by the slow growth, or failure to grow, of certain serotypes in culture, the antigenic diversity among the serotypes, and the low titer of virus in certain clinical specimens. Within the past 6 years, applications of molecular cloning techniques, in vitro transcription vectors, automated nucleic acid synthesis, and the polymerase chain reaction have resulted in significant progress toward nucleic acid-based detection systems for the enteroviruses that take advantage of conserved genomic sequences across many, if not all, serotypes. Similar approaches to the study of enteroviral pathogenesis have already produced dramatic advances in our understanding of how these important viruses cause their diverse clinical spectra.

The hearts of eight patients aged 22 to 67 years (mean, 41 years) who died during or within 4 days of interleukin-2 (IL-2) based immunotherapy for treatment of renal cell carcinoma or melanoma were studied at necropsy. Death resulted from combined cardiorespiratory failure in two patients, sepsis in four patients, acute myocardial infarction in one patient, and myocarditis in one patient. Transmural left ventricular necrosis was present in one of the two patients with significant atherosclerotic coronary artery narrowing. Noninfectious myocarditis was present in five patients: the inflammatory infiltrate was lymphocytic in four and composed of a mixture of eosinophils and lymphocytes in one. Although treatment-related deaths associated with high-dose IL-2 therapy are uncommon (1.5% in 652 consecutive patients), the potential for significant myocardial ischemia or myocarditis exists, and careful monitoring for arrhythmias or myocardial failure is warranted.

The authors reviewed the initial presentation of seven infants with acute myocarditis. All patients presented with respiratory distress including tachypnea (respiratory rate greater than or equal to 40) and intercostal retractions. Other findings included tachycardia (heart rate greater than or equal to 120) (7/7) and grunting (6/7). Lungs were clear to auscultation in six out of the seven patients. Cardiomegaly was seen in five of the initial chest roentgenograms. Each initial electrocardiogram had abnormal findings. Initial diagnoses were sepsis and shock in three patients, pneumonia and asthma in two, and congestive heart failure in two. Six patients required tracheal intubation. All required admission to the Pediatric Intensive Care Unit (ICU). Two patients died. Myocarditis should be suspected in a child presenting with severe respiratory distress, tachycardia, cardiomegaly, and/or an abnormal electrocardiogram. Prompt stabilization and admission to a pediatric intensive care unit for further evaluation and treatment is essential.

Eleven patients with Hodgkin's disease were treated with high-dose chemotherapy followed by autologous bone marrow transplantation (ABMT). Four patients were resistant to initial therapy and 7 patients had relapsed but were progressing under second or third line therapy. The median time from initial diagnosis to transplantation was 44 months (range, 16 to 82). In 9 patients pre-ABMT consisted on high-dose CVB cyclophosphamide, etoposide and carmustine) chemotherapy, one patient was treated with BACT protocol (carmustine, cytosine arabinoside, cyclophosphamide and thioguanine) and other patient was treated with high-dose of busulfan and melphalan. In 8 patients complete remission (CR) was achieved, in one the remission was partial, one failed to respond and one case was not evaluable due to early death. Among CR patients, 2 died from late toxicity, and the other 6 remain in CR off therapy, one of them more than 33 months after ABMT. High-dose therapy produce severe myelosuppression in all patients. There were 3 treatment related death: one early death due to hemorrhagic myocarditis, one veno-occlusive disease of the liver and one due to cytomegalovirus sepsis. The high complete response rate in these heavily pretreated patients suggests that there may be an indication for high-dose therapy and ABMT in earlier resistant Hodgkin's disease. Moreover under such conditions, treatment related morbidity would be expected to be lower.

The use of interleukin-2 (IL-2), either alone or in combination with lymphokine-activated killer cells, tumor infiltrating lymphocytes, or other immunotherapeutic agents has added a new list of alternatives to conventional antineoplastic regimens. Little information is available about the pathologic changes occurring in patients treated with these agents. In this study, we reviewed the necropsy materials from 19 patients, 12 men and 7 women, with a variety of malignancies including melanoma, renal cell carcinoma, gastrointestinal and pulmonary adenocarcinoma, and metastatic gastrinoma, who died after receiving IL-2-based immunotherapy. Death occurred at intervals ranging from less than 1 hour to 143 days following the last dose of therapy. All patients dying at or less than 43 days following cessation of therapy had lymphoid infiltrates of varying intensity in residual tumor. At necropsy, the major cause of death unrelated to the presence of metastatic tumor was bacterial sepsis. In addition, we found evidence of significant cardiac and pulmonary toxicity: two patients with acute myocardial infarction, one with and one without significant coronary artery disease, two cases of unexplained lymphocytic myocarditis, and one case of fatal pulmonary capillary plugging following an infusion of lymphokine-activated killer cells. Thus, not unlike other forms of therapy for cancer, IL-2-based immunotherapy does not appear to be without significant toxicity.

Giant-cell myocarditis is a rare inflammatory disorder characterized by degeneration and necrosis of myocardial fibers and presence of chronic inflammatory infiltrates associated with multinucleated giant cells forming a granulomatous inflammatory reaction. The etiology of giant-cell myocarditis is unknown. Many conditions have been reported as associated with this phenomenon such as fungi, virus, sarcoidosis, and hypersensitivity or autoimmune reactions. We are reporting a case of giant-cell myocarditis discovered in a newborn with congenital herpetic sepsis. The myogenic origin of the giant-cells of this case is supported by the positivity for desmin and myoglobin and negativity for muramidase and alpha-1-antichymotrypsin after immunoperoxidase procedure. The presence of Herpes simplex virus type II was confirmed by indirect immunoperoxidase reaction in most of the viscera including the heart, but is not considered a factor in the production of giant cells.
