Prospective comparison of QOL before and 6 months after intensive care unit (ICU) admission in a 12-bed noncoronary medical ICU of a university hospital. All 325 consecutively admitted adult patients who spent at least 24 h on the ICU were eligible. QOL measurements were collected before and 6 months after ICU admission. Comorbidity classified by the Charlson index was 2.44 +/- 1.96. Mean stay in the ICU was 10.4 +/- 15.1 days, mean Acute Physiology and Chronic Health Evaluation II score was 23 +/- 10. Cumulative mortality was: ICU 24 %, hospital 34 %, 6 months 43 %. Relative to baseline, follow-up interviews of 185 survivors revealed no significant changes in the overall QOL score (p = 0.93). The subscales basic physiological activities (p = 0.07) and normal daily activities (p = 0.15) showed a nonsignificant deterioration. A significant improvement was noted for the domain emotional state (p = 0.013). Six months after admission to a medical ICU most survivors had regained their preadmission health-related QOL. Multivariate analysis showed that preadmission QOL, age, and severity of illness were most strongly associated with follow-up QOL. Of the survivors 86 % were living at home, and all but one of those previously in employment had returned to their former work. Most patients (94%) would undergo ICU treatment again if necessary.

The aim of our study was a) to determine the frequency and intensity of HHH in the bone marrow of patients who died on the medical intensive care unit; b) to analyze morphologic bone marrow changes; and c) to identify possible risk factors and their interactions in the pathogenesis of HHH. A retrospective observational analysis of clinical data and autopsy findings including histologic and immunohistological analysis of bone marrow to characterize cellularity, siderosis, hemophagocytosis, and T-cell infiltrates. The medical intensive care unit of a university hospital. Patients were 107 consecutive patients who died and underwent autopsy. None. HHH was identified in 69 of the 107 patients (64.5%). Moderate to severe HHH was present in 35 of the 107 bone marrows. Univariate risk factor analysis showed that HHH was associated with various intrinsic and extrinsic factors. However, multivariate analysis identified the intensity of therapeutic interventions--represented by the Therapeutic Intervention Scoring System--as the only positive, and cardiovascular disease as the only significant negative, predictor of HHH (p <.05). Routine laboratory tests were of no value in predicting the presence of HHH. The intensity of HHH correlated significantly with siderosis and T-cell infiltrates (p <.05) but not with bone marrow cellularity. HHH is common in medical intensive care unit nonsurvivors. Treatment intensity and a noncardiovascular cause of death are predictors of HHH. Sepsis and blood transfusion may have a synergistic effect on the triggering of HHH. HHH in bone marrow is associated with enhanced T-cell infiltrates, suggesting that T cells may play an important role in its mediation.

Bacillus cereus was isolated from bronchoalveolar lavage fluids, blood cultures, and pseudomembrane biopsy specimens; despite intensive antibiotic treatment, the patient's condition deteriorated rapidly. To our knowledge, this is the first report of a B. cereus infection that has caused pseudomembranous tracheobronchitis, possibly because of the production of bacterial toxins.
