Fifty consecutive episodes of septicemia were studied in 41 children who had acute lymphoblastic leukemia. Seventy-six percent of these episodes occurred when the absolute granulocyte count was 200/mm3 or less and were caused by gram-negative enteric and gram-positive mucocutaneous bacteria. In eight patients, Streptococcus pyogenes was isolated at the time when ALL was diagnosed. Multiple anaerobic and aerobic isolates from a single blood culture were associated with abdominal distress, whereas Streptococcus pneumoniae and Hemophilus influenzae septicemia occurred in associated with respiratory illnesses. When patients with severe compromise of anatomic barriers or respiratory disease were excluded, 94% of all patients with septicemia had an AGC of less than 200/mm3. The data provide guidelines for treatment for febrile patients with ALL based upon the AGC, the phase of the disease, and on the presence of associated respiratory or abdominal findings.

Between January 1972 and December 1976 201 preterm infants and neonates were treated with mechanical ventilation. These children were classified into 6 groups according to the indications for mechanical ventilation: P = respiratory failure caused by pulmonary disease; Z-P = respiratory failure caused by cerebral disturbance with simultaneous respiratory disease; Z = respiratory failure caused by cerebral disturbance; C = respiratory failure caused by cardiac disease; SCH = respiratory failure through shock; M = respiratory failure caused by mechanical disturbance; Bronchopulmonary complications developed in 70% of the survivors and in 60% of the fatalities. The most serious bronchopulmonary complications were infections which occured with similar frequency in all indication groups as late-onset complications, and air-leaks which occured as early complications. The latter complication was significantly higher (38%) in the first than in the other groups. The most serious extrapulmonary complications were seizures, intracerebral hemorrhages and septicemia. 71 of the 201 patients survived. There was a significant increase in the survival rate from 21.2% in 1972-1973 to 43% in 1974-1976. The survival rates differed significantly within the indication groups. The best result was found in the p-group followed by the Z-group. The highest mortality rate was found in the SCH and C-group.

Risk factors, clinical syndromes and the case-fatality rates associated with Group B Streptococcus (GBS) infections in infants managed at the University of Rochester Medical Center during 1979 to 1989 were reviewed. Overall 92 episodes of early onset disease (EOD) and 54 of late onset disease (LOD) were diagnosed in 143 infants (3 infants with EOD presented later with LOD). About one-third of patients with EOD and controls were non-white compared with two-thirds of patients with LOD that occurred in racial minority groups. Prematurity and low birth weight were significantly more common in patients with invasive GBS disease than in controls. Eighty-three of 92 (90%) cases of EOD were detected during the first day of life and 10 of 54 (19%) cases of LOD occurred in infants older than 3 months of age. At the time of diagnosis 4% of infants with EOD were asymptomatic, 54% had respiratory disease, 27% had sepsis without a focus, 15% had meningitis and 1% had urinary tract infection or omphalitis. Among infants with LOD 46% had sepsis, 37% meningitis, 7% urinary tract infection, 6% osteomyelitis and/or septic arthritis and 4% cellulitis or pneumonia. Leukopenia and shift to the left were observed in 43 and 61% of episodes of EOD and in 28 and 57% of episodes of LOD, respectively. All infants were promptly treated with antibiotics and vigorous supportive therapy. The case-fatality rate was 13% in EOD and 0 in LOD.(ABSTRACT TRUNCATED AT 250 WORDS)

Clinical manifestations and autopsy findings on 23 patients who died of acute sepsis of Escherichia coli origin lead the authors to the conclusion on polymorphic clinical run of the disease. It varies with premorbid background (food intoxication, acute respiratory disease in decompensated diabetes mellitus, chronic somatic disorders) and risk factors (inadequate antibacterial therapy, nervous strain, fatigue). Inadequate antibacterial therapy promoting dysbacteriosis aggravated preexisting pathomorphological shifts in the intestine likely after toxic infection, diabetes-specific foci, contributed to the onset of intestinal sepsis.

Genetic diversity among 22 Escherichia coli strains isolated from chickens with swollen-head syndrome (SHS), an acute respiratory disease of domestic poultry, and 93 strains isolated from birds with colibacillosis was assessed on the basis of allelic variation at 20 enzyme-encoding loci detected by multilocus enzyme electrophoresis. SHS isolates from Spain and Canada were polymorphic at 14 loci and were classified into 19 multilocus genotypes, defining clones that differed on average at 34% of the loci. In most cases, SHS isolates of different clonal genotypes were distinct in O:H serotype and expressed different fimbrial antigens. Comparisons with 93 isolates obtained from birds with colibacillosis revealed enzyme polymorphisms at 17 of 20 loci, with an average of 3.5 alleles per locus. In the total sample, 56 clonal genotypes were distinguished, with 27 (23%) of the isolates belonging to one of three common clones. Both SHS and colibacillosis isolates were genetically diverse, with an average single-locus diversity of 0.36, indicating that a wide variety of naturally occurring bacterial clones is associated with these acute avian infections. Six previously defined groups of clones identified in diseased birds from the United States were represented in isolates from Spain, indicating that similar clones occur in widely separated geographic areas. In addition, one group of SHS isolates was closely related to a recognized widespread clone complex incriminated in human septicemia and meningitis. The results suggest that certain strains implicated in SHS infections belong to a clone complex whose members have special attributes that promote involvement in invasive diseases in humans and animals.

Iron deficiency is prevalent in childhood in the developed and developing countries. Programs of presumptive therapy, mass supplementation and food fortification have been introduced in many countries. The unresolved debate over the interaction of iron and infection in the clinical setting prompts re-evaluation of these practices. Situations of iron overload are associated with increased susceptibility to certain infections, although the exact mechanisms may vary with the main pathology. Iron treatment has been associated with acute exacerbations of infection, in particular malaria. In most instances parenteral iron was used. In the neonate parenteral iron is associated with serious E. coli sepsis. In one country, with endemic malaria, parenteral iron was associated with increased rates of malaria and increased morbidity due to respiratory disease in infants. In contrast in non-malarious countries studies of oral iron supplementation have if anything shown a reduction in infectious morbidity. Methodological problems in the latter reports indicate the need for further controlled prospective studies with accurate morbidity recording if informed recommendations are to be made.

A retrospective study of amyloidosis in pigtailed macaques (Macaca nemestrina) at the Washington Regional Primate Research Center (WRPRC) was conducted. Between 1971 and 1985, 248 of 1,952 (13%) necropsies revealed amyloidosis in pigtailed macaques. The influence of demographic factors, diseases and experimental interventions on amyloidosis was examined. Univariate analyses, using two controls for each case, indicated that age, sex, birthplace and residence were related to amyloidosis. After adjusting for age, females were not at greater risk. However, monkeys born at the WRPRC were at greater risk and monkeys 0 to 5 years old residing at the breeding colony were at greater risk than monkeys at the research center. After adjustment for age, monkeys were at greater risk of developing amyloidosis if they had a history of episodes of diarrhea, respiratory disease or trauma. As the number of episodes increased, the risk increased. Monkeys with retroperitoneal fibromatosis, a manifestation of simian D retrovirus infection, were also at greater risk. Using logistic regression and controlling for age, sex, birthplace and residence, monkeys with diarrhea remained at an elevated risk for amyloidosis. Compared with a model combining diarrhea, respiratory disease, septicemia, surgery, trauma and retroperitoneal fibromatosis, a model with diarrhea alone accounted for most of the increased risk.

The incidence of nosocomial infections is studied retrospectively, among 174 patients with a chronic respiratory disease, in a ICU during one year (1987). The medium-age is 65 years (range: 19-87 years); the sex-ratio is 125/50 (men/women); 88 (50%) are ventilated; 48 (27%) meet with a nosocomial infection during their stay in the unit. This superinfection involve 61% of the deaths. The lung involved in 67% of the cases, a septicemia from a venous catheter is found in 18% and an infection of the urinary tract in 15%. The nosocomial pneumonias are always the outcome of the ventilation. The Gram-negative bacilli are the most frequent, particularly Pseudomonas aeruginosa (44%). The initial gravity promote the superinfection (SAPSE with superinfection: 16.63 +/- 5.67/without 11.43 +/- 4.59 p less than 0.001). The superinfection involve a prolongation of the ventilatory time (with 27.52 +/- 31.14 days/without 7.27 +/- 7.05 days p less than 0.001). The gravity and the frequency (28%) of the nosocomial infections set the problem of the antibioprophylaxis.

The lesions and etiologic agents associated with 13 outbreaks of respiratory disease in commercial chickens were investigated. Adenoviruses were isolated from tracheal and lung tissues of affected chickens in all 13 outbreaks. Escherichia coli was isolated from the lung of an occasional bird. The tracheal specimens were consistently negative for Bordetella avium, but E. coli and occasionally Staphylococcus aureus were isolated. There was also serological evidence in one outbreak, and pathological evidence in another, of a concurrent infectious bursal disease virus (IBDV) infection of chickens affected with the disease. Gross and microscopic alterations in the tracheas and lungs of affected chickens were similar in all outbreaks and consisted of catarrhal tracheitis and occasionally multifocal pneumonia with mononuclear cell infiltrates. Hepatitis and splenitis with heterophil infiltrates occasionally were seen in birds with coliform septicemia. The tracheal and lung lesions in the present investigation were considered primarily of adenovirus etiology, complicated by secondary bacterial infection.

Two controversial issues of neonatal transfusion practices, erythrocyte 'booster' transfusions and granulocyte transfusions, are critically reviewed, and current recommendations for transfusion practices are made. Infants should receive erythrocyte transfusions to treat congestive heart failure caused primarily by anemia. It is customary to maintain the hematocrit at greater than 40% in neonates with severe respiratory disease, although the efficacy of this practice has not been firmly established. Erythrocyte transfusions seem to be indicated for infants with anemia plus recurrent apnea, poor weight gain or the syndrome of tachycardia, tachypnea, dyspnea and poor feeding for which no other cause can be found. Granulocyte transfusions are likely to benefit seriously ill neonates exhibiting all three of the following: strong evidence of bacterial sepsis, neutropenia (compared to age-related normal values) and a diminished marrow neutrophil storage pool. Granulocyte transfusions for septic infants expressing only one or two of these features should be considered to be experimental therapy.
