Widespread use of antibiotics and change in pathogenesis altered the bacteriology of infected aortic aneurysms. In the past, bacterial endocarditis was the major source of emboli infecting the aorta. Now, gram-negative sepsis in elderly patients is often the initiating event of infection in atherosclerotic aneurysms. Four cases of gram-negative infection in aortic aneurysms were treated. The etiology, presentation, and surgical management are reviewed. Three abdominal aortic aneurysms were infected during urinary tract sepsis and one infection occurred with Salmonella septicemia. The clinical triad of fever, abdominal pain, and a pulsatile abdominal mass led to a preoperative diagnosis in three of four patients. Debridement of infected tissue and bypass through non-infected tissue planes remain the cornerstones of modern surgical management. Despite prompt diagnosis and proper surgical management, the mortality of gram-negative aortic infection remains high because of early rupture and extensive atherosclerotic disease.

To study the etiology of neonatal septicemia and factors associated with outcome, all charts of neonates with bacteremia and clinical sepsis admitted to a neonatal unit in Saudi Arabia, from 1 November 1980 to 31 October 1984 were reviewed. The results were compared to a previous study period in the unit (1 November 1976-31 October 1980). Septicemia was diagnosed on 50 occasions in 49 neonates. The incidence of neonatal sepsis among patients born in the hospital was 2.5/1,000 live births. Mortality from sepsis was 33% and was associated with neutropenia in 63%. The most commonly isolated bacteria were E. coli, Klebsiella and Staphylococcus aureus. Salmonella enteritidis serotypes were isolated in 4% of the cases. Group B streptococci (GBS) were isolated, for the first time, from blood of 3 neonates. Salmonella species were less frequently and GBS more often isolated than previously. GBS have now appeared as etiologic organisms in neonatal sepsis also in Saudi Arabia. Salmonella septicemia remains more common in Saudi Arabia than in the West.

Of seven infants with Salmonella sepsis, three had meningitis. A review of these cases and others previously reported demonstrated that among infants less than 1 year old in Arkansas, Salmonella infection developed in 383 over a 31/2-year period. The reported incidence of sepsis and/or meningitis was 1.8%; for those less than 2 months of age, it was 5.0%. Epidemiologic investigation failed to disclose a consistent source of the Salmonella colonization for young infants. Treatment of meningitis with ampicillin sodium was frequently associated with relapse or clinical failure, while chloramphenicol or a chloramphenicol-ampicillin combination appeared to offer superior efficacy. Consideration should be given to antibiotics for the routine treatment of Salmonella gastroenteritis in infants less than 3 months of age.

The authors report a case of a 36-week male infant born via spontaneous vaginal delivery who developed Salmonella sepsis at HRH Princess Maha Chakri Sirindhorn Medical Center Srinakharinwirot University, Nakhon Nayok, Thailand. He was born to a mother without identifiable risk factors. On day 3, he developed fever tachycardia, lethargy, poor feeding and diarrhea prompting a sepsis evaluation. Blood and stool cultures were positive for S. enterica serovar 4,5,12:i:-. Therefore, Salmonella infection should be considered in the differential diagnosis of early onset neonatal sepsis (EOS) particularly in endemic areas.
