Based on a three year surveillance in the neonatal intensive and transitional care nurseries (NICU) at the Hospital of the University of Pennsylvania (HUP), an analysis of all cases of nosocomial bacteremia was made. From January 1982 to September 1984, a total of 57 nosocomial bacteremic episodes were identified. This gave a rate of 3.6 episodes per 100 NICU admissions or 6.5 per 1000 live hospital births. While coagulase-negative staphylococci (CNS) accounted for approximately 40 percent of all positive blood cultures, it was responsible for 73 and 66 percent of the nosocomial bacteremias in 1982 and 1983, respectively. In 1984, coagulase-negative staphylococcus was the responsible pathogen for 92 percent of all nosocomial bacteremic episodes. Of 139 infants weighing less than or equal to 1250 g at birth, 30 (22 percent) developed CNS bacteremia. The risk of coagulase-negative staphylococcus bacteremia was associated with low birth weight, respiratory distress, prolonged hyperalimentation, and multiple supportive measures. Infants were treated with vancomycin hydrochloride, as most of the CNS were resistant to methicillin and/or gentamicin. There were no deaths related to coagulase-negative staphylococcal septicemia.

In the early 1980's methicillin-resistant staphylococcus aureus (MRSA) was reported as a major pathogenic organism of geriatric hospital infection in Japan. At the same time in the A geriatric hospital MRSA infection was prevalent. To decrease nosocomial infections some active preventive measures against hospital infection were taken since Oct. 1991. About a year before introduction of prevention of hospital infection in the geriatric ward (190 beds) of A hospital 193 episodes of nosocomial bacteremia were observed. However a year after introduction of preventive measures episodes of nosocomial bacteremia were decreased to less than a half (45.6%) in comparison to the number before introduction of prevention. As a causative organism gram-positive bacteria including MRSA were markedly decreased. Major portals of entry of bacteremia (74.9%) were urinary-tract system, intravenous hyperalimentation (IVH) catheter, and pressure sores. MRSA-positive pressure sores were decreased to 20.4% of those before prevention. On the other hand 87 episodes of nosocomial pneumonia were observed before prevention. However a year after introduction of preventive measures episodes of nosocomial pneumonia were decreased to less than a half (44.8%) in comparison to the number before introduction of prevention. After prevention MRSA and mixed infection of P. aeruginosa and MRSA were markedly decreased. The decrease of bacteremia and nosocomial pneumonia were caused by cleaning hands, the preventive measures for decrease and improvement of pressure sores, cleaning the upper respiratory tract for prevention of lower respiratory-tract infection cleaning floors and education of the staff, etc.

BACKGROUND Infectious aortitis has a poor prognosis and high mortality rate if untreated. Here, we report a case of rupture of infectious aortitis induced by methicillin-resistant staphylococcus aureus (MRSA). CASE REPORT An 83-year-old female patient was hospitalized due to continuous fever and diarrhea, which was diagnosed as colitis. The colitis was determined to have been induced by small vessel vasculitis upon histological examination. Fasting and central venous hyperalimentation using a peripherally inserted central catheter (PICC) were carried out for rest of the intestine. Swelling and pus were observed at the insertion site of the PICC. Since methicillin resistant staphylococcus aureus (MRSA) was detected in the culture of the pus and the blood, the patient was treated with vancomycin. After confirming that the blood culture became negative, prednisolone (PDL) was started as therapy for the colitis. Her diarrhea and fever improved. After vancomycin was stopped, MRSA-arthritis appeared. She suddenly died due to acute massive hemorrhage into the mediastinum and left thoracic cavity from the atherosclerotic ulcer of the thoracic aorta. It took 98 days from the first detection of MRSA in her blood to her death. We found gram-positive coccus in the ruptured aortic ulcer and we also detected MRSA gene by polymerase chain reaction in the ulcer. These results suggest that MRSA could colonize in the aortic ulcer during the MRSA-bacteremia and the MRSA could contribute to the vulnerability of the aortic wall. CONCLUSIONS After septicemia occurrs in an elderly person, the patient should be followed up by considering infectious aortitis, especially when the patient has several risk factors.
