Staphylococcal infections in the intensive care unit

Staphylococcus aureus and coagulase-negative staphylococci are among the most common causes of nosocomial infections in the intensive care unit (ICU). The clinical presentation of staphylococcal device-related infections, pneumonias, or surgical wound infections is not unique. However, treatment of these infections is increasingly problematic because of the resistance of clinical isolates to a widening number of antimicrobial agents.The confluence of critically ill patients and the need for multiple invasive procedures, as well as the use of broad-spectrum antimicrobial agents in the ICU, set the stage for the emergence of these multidrug-resistant staphylococci. In the past 10 years, there has been a progressive increase in the overall resistance of staphylococci to antimicrobial agents. Conventional infection control measures, such as handwashing and isolation precautions, to prevent the spread of staphylococcal infections in the ICU setting remain of critical importance. New approaches, including the prophylactic use of topical antistaphylococcal agents to eliminate nasal colonization in high-risk ICU patients and the development of antistaphylococcal vaccines, are currently being investigated.     

Diarrhea in neonatal intensive care unit

AIM:To investigate the frequency,etiology,and current management strategies for diarrhea in newborn.METHODS:Retrospective,nationwide study involving 5801 subjects observed in neonatal intensive care units during 3 years.The main anamnesis and demographic characteristics,etiology and characteristics of diarrhea,nutritional and therapeutic management,clinical outcomes were evaluated.RESULTS:Thirty-nine cases of diarrhea(36 acute,3 chronic) were identified.The occurrence rate of diarrhea was 6.72 per 1000 hosp...     

Pseudomonas aeruginosa infections in a neonatal intensive care unit

This report describes a cluster of nosocomial infections with Pseudomonas aeruginosa in a neonatal intensive care nursery. All 5 cases of P aeruginosa infection were clustered in September 1999. Aggressive infection control measures were instituted, including installation of a user-friendly handwashing soap and environmental cleaning. On the basis of the finding of persistent dirty equipment, a new full-time position was created that was dedicated to equipment cleaning. These measures were effective in eliminating the cluster. The nursery has remained free of P aeruginosa infection for more than 2 years, attesting to the success of our program.     

Human bocavirus infection in a neonatal intensive care unit

Human bocavirus (HBoV) plays a non-insignificant role as a pathogen in respiratory tract diseases in the pediatric population, especially in infants younger than 2 years of age. In this paper, we have described two cases of a possible nosocomial infection in a neonatal intensive care unit being HBoV the sole detected respiratory virus in clinical samples.     

Nosocomial infections in the neonatal intensive care unit

Nosocomial infections are significant causes of morbidity and mortality in patients who require newborn intensive care. The most common bacterial pathogens are Gram-positive bacteria, including Staphylococcus epidermidis, Staphylococcus aureus, and Enterococcus species. Gram-negative enteric bacilli and Gram-negative environmental bacteria are involved in outbreaks and occasional cases of nosocomial infection. The incidence of fungal infection has increased over the past 10 years; fungemia is the most commonly recognized infection. Surveillance for nosocomial infection is essential to identify outbreaks and detect unsuspected reservoirs of pathogens. A variety of molecular techniques can be used to determine the genetic relatedness of pathogens. Prevention of infection requires the identification of contaminated equipment, education regarding infection control methods including hand washing, and the judicious use of antimicrobial agents.     

Report on results of an intensive care unit at a district hospital]

The experiences of an internal intensive observation and therapy unit in a district hospital are reported. During 4 years 2,803 patients were admitted. 65% showed life-threatening disturbances of the heart and of the circulation. Arrangement of the rooms, personal staff as well as special diagnostic and therapeutic methods are described.     

Health care-associated infections in the neonatal intensive care unit

Neonates represent a unique and highly vulnerable patient population. Advances in medical technology that have occurred over the last few decades have improved the survival and quality of life for neonates, particularly those infants born with extreme prematurity or with congenital defects. Although immunologic immaturity and altered cutaneous barriers play some role in the vulnerability of neonates to nosocomial infections, clearly, therapeutic interventions that have proven to be lifesaving for these fragile infants also appear to be associated with the majority of infectious complications resulting in neonatal morbidity and mortality. Rates of infections in neonatal intensive care units (NICUs) have varied from 6% to 40% of neonatal patients, with the highest rates in those facilities having larger proportions of very low-birth-weight infants (birthweight < or =1000 grams) or neonates requiring surgery. Efforts to protect the vulnerable NICU infants include the following: (1) optimal infection control practices, especially good hand hygiene and good nursery design; (2) prudent use of invasive interventions with particular attention to early removal of invasive devices after they are no longer essential; and (3) judicious use of antimicrobial agents, with an emphasis on targeted (narrow spectrum) rather than broad-spectrum antibiotics and appropriate indications (proven or suspected bacterial infections).
