Case Reports[Antibiotic-resistant Corynebacteria--a new problem of infection in immunosuppressed patients].
Corynebacterium species can normally be found on the skin and mucous membranes but rarely cause infections. They are sensitive to most antibiotics. Two patients with severe aplastic anemia undergoing antilymphocyte globulin therapy developed septicemia with a highly antibiotic-resistant corynebacterium (JK-group) only sensitive to vancomycin. ⋯ One patient was even colonized with corynebacterium for several months before. If this strain is detected in the blood when new fever develops during prolonged neutropenia and broad-spectrum antibiotic therapy, it indicates serious infection in these highly compromised patients. Both cases illustrate that regular microbial surveillance can help to reveal colonization of high risk patients with multiple antibiotic-resistant corynebacterium strains and thus allow early initiation of treatment with vancomycin, which is the only effective antibiotic.

Comparative Study
Bacteremia in narcotic addicts at the Detroit Medical Center. II. Infectious endocarditis: a prospective comparative study.
For one year all narcotic addicts admitted to the Detroit Medical Center with infectious endocarditis (74 cases) were compared with a control group of bacteremic addicts who had other infections (106 cases). Endocarditis was caused by Staphylococcus aureus (60.8% of cases), streptococci (16.2%), Pseudomonas aeruginosa (13.5%), mixed bacteria (8.1%), and Corynebacterium JK (1.4%). S. aureus endocarditis most frequently involved the tricuspid valve; streptococci infected left-sided valves significantly more often than other organisms (P = .001). ⋯ Polymicrobial bacteremia in the nonendocarditis group was associated with markedly increased morbidity. Mild hyponatremia occurred in 41% of all patients and was also associated with significantly increased morbidity. Analysis of the two groups disclosed similarities and differences with implications for the pathophysiology and treatment of addicts with bacteremic infection.

A lethal case of Adult Respiratory Distress Syndrome (ARDS) consequent to meningococcal septicemia is clinically and physiologically described. Very high levels of eosinophil cationic protein and lactoferrin in bronchoalveolar lavage were observed in spite of peripheral eosinopenia and neutropenia. These findings provide support for the hypothesis that activated granulocytes are involved in the pathogenesis of septic-induced ARDS.

From August 1980 through July 1984, 19 neonates had sepsis due to Haemophilus influenzae. Onset of disease occurred within 48 hours after birth of all the neonates. One neonate was born at term and 18 were born prematurely, including seven neonates born before 28 weeks' gestation. ⋯ In 14 cases, isolates were biotyped yielding eight with biotype II, four with biotype III, and one each with biotypes IV and V. Neonatal sepsis due to nontypable H influenzae is now nearly as common as sepsis due to group B Streptococcus. Both organisms produce diseases with many features in common, especially fulminant courses with respiratory distress and pneumonia, and often have a fatal outcome.

Resolution of fever in Staphylococcus aureus septicaemia--retrospective analysis by means of Cusum plot.
The treatment of Staphylococcus aureus septicaemia continues to be an important clinical challenge. Spikes of fever during antibiotic therapy complicate assessment of the response. In an attempt to analyse response to treatment in terms of resolution of fever we have retrospectively studied 17 patients with microbiologically proven S. aureus septicaemia. ⋯ When the Cusum data were used, the time to defervescence of fever from the onset of antibiotic treatment was 21.7 h (range 8-96 h) and to abolition of fever 58.3 h (range 12-180 h). Antibiotic treatment was changed in 61% of patients on the basis of continued fever shown on the conventional temperature chart. In all of these patients, however, the Cusum plot showed clear evidence of response.
