To investigate the incidence, risk factors and mortality of ventilator-associated pneumonia (VAP) in intensive care unit (ICU) patients. ⋯ The incidence of VAP in our ICU is 23.1%. Length of ICU stay and an admission diagnosis other than trauma are major risk factors for the development of this nosocomial infection. VAP is associated with a high fatality rate. However, after adjustment for disease severity and length of ICU stay, VAP was not identified as an independent predictor of death.

Comparative Study
Invasive aspergillosis in critically ill patients: analysis of risk factors for acquisition and mortality.
To investigate outcome in patients who develop invasive aspergillosis in the ICU, and to evaluate whether specific risk factors for the acquisition of invasive aspergillosis are associated with mortality. ⋯ The incidence of invasive aspergillosis in this series is 4/1000 admissions. No difference in mortality was found between patients with and without risk factors for the acquisition of invasive aspergillosis. Yet, the prognosis of the patients without risk factors seems to alter more seriously by the development of this infection.

Historical Article
The one fixed point in a changing age. An analysis of half-secular trends among original papers published in The Lancet 1945-95.
We performed a systematic survey of original papers published in The Lancet throughout the years 1945, 1946, 1970 and 1995. The Lancet was chosen due to a conservative layout through these years, and the year 1946 added to the analysis to ponder for any war-induced bias. The general layout and structure of the journal were indeed maintained throughout these years. ⋯ Major changes were observed in the area of origin of the papers, from an overwhelming British Isles' preponderance (87% of papers published in 1945) to a partake with Continental Europe, America and international groups (27, 33, 15 and 12%, respectively of the 1995 papers). The most often addressed fields of medicine shifted from war-, surgery- and microbiology-related subjects in 1945 towards cardiology-, oncology-, and virus-related works in 1995. The most impressive and enduring change was the increase in the use of statistical tools for data analysis and presentation (0.3% of papers in 1945 vs. 60% in 1995).

To validate the safety profile of a rapid ELISA D-dimer as the first diagnostic step in the clinical suspicion of pulmonary embolism (PE) in outpatients admitted to an emergency department (ED), and to retrospectively evaluate the appropriateness of the physician's prescription. ⋯ This observational study confirms that a normal rapid ELISA D-dimer value (< 500 ng/ml) used as a first diagnostic step in ruling out the diagnosis of PE is a safe clinical practice when the pre-test clinical probability is low or intermediate. Nevertheless, the low prevalence rate of the disease (8.1%) suggests a potential overused and inappropriate prescription.
