Comparative Study
Noninvasive nasal mask ventilation beyond the ICU for an exacerbation of chronic respiratory insufficiency.
To assess the usefulness of noninvasive nasal mask ventilation (NMV) in the treatment of an exacerbation of chronic respiratory insufficiency in patients stable enough to be admitted to a non-ICU ward. ⋯ NMV associated with standard treatment may be more beneficial than conservative treatment alone for improving blood gas exchange in patients with chronic respiratory insufficiency admitted to the hospital (but not the ICU) for an episode of acute decompensation and respiratory acidosis.

To determine if temperature during cardiopulmonary bypass (CPB) has an effect on perioperative and postoperative thyroid function. ⋯ The results of this study suggest that normothermic CPB does not prevent the development of the "euthyroid sick syndrome" during and after CPB. Despite these changes in thyroid function, most patients in both groups had a normal postoperative recovery.

Case Reports
Three-dimensional image reconstruction of partial anomalous pulmonary venous return to the superior vena cava.
A case of a rare partial anomalous pulmonary venous return of the right upper lobe into the superior vena cava is reported. Multiple three-dimensional image reconstructions in association with spiral CT are used in the aim of clarifying this abnormality of pulmonary venous drainage.

Health status and quality of life (QOL) in lung transplant candidates and recipients were compared to determine the impact of transplantation, and whether recipients experience continued improvements in the years after transplant surgery. ⋯ Dramatic improvements in health status and QOL occur after successful lung transplant and remain stable over time. Obliterative bronchiolitis results in notable QOL reductions.

The thresholds of the diagnostic procedures performed to diagnose ICU-acquired pneumonia (IAP) are either speculated or incompletely tested. ⋯ Using the classic thresholds, sensitivity was 67% for PSB, 54% for PTC, 59% for BAL D, and 77% for BAL C. Specificity was 88% for PSB, 77% for PTC, 98% for BAL D, and 77% for BAL C. We used receiver operating characteristics methods to reappraise thresholds. Decreasing the thresholds to 500 cfu/mL for PSB, 10(2) cfu/mL for PTC, 2% cells containing bacteria for BAL D, 4 x 10(3) cfu/mL for BAL C increased the sensitivities (plus 14%, 23%, 25%, 10%, respectively) and moderately decreased the specificities (minus 4%, 9%, 2%, 4%, respectively) of the four examinations. The association of PSB with a 500 cfu/mL threshold and BAL D with a 2% threshold recovered all but one episode of pneumonia (SE 96 +/- 4%) with a 84 +/- 10% specificity. For a similar ICU population, these "best" thresholds increased negative predictive value with a minimal decrease of positive predictive value. They need to be confirmed in multiple ICU settings in prospective fashion.
