Non-invasive ventilation in chronic hypercapnic COPD patients with exacerbation and a pH of 7.35 or higher.
Current guidelines suggest the use of non-invasive ventilation (NIV) in hypercapnic chronic obstructive pulmonary disease (COPD) exacerbations in patients presenting with a pH of 7.25-7.35. The aim of this study was to investigate the role of NIV in COPD patients with chronic hypercapnic respiratory failure admitted to the hospital with acute exacerbations and an arterial pH of 7.35 or higher. ⋯ Early administration of NIV in COPD patients with chronic hypercapnic respiratory failure admitted for acute exacerbations with a pH of 7.35 or higher results in a reduced hospital stay and faster improvement of arterial blood gases.

Brain natriuretic peptide increases in septic patients without severe sepsis or shock.
B-type natriuretic peptide (BNP) production increases in critically ill septic patients. We assessed the hypothesis that BNP is elevated in patients with community-acquired infections without severe sepsis or septic shock. ⋯ BNP levels are elevated in the acute phase of community-acquired microbial infections without severe sepsis or septic shock.

Life-threatening megaloblastic pancytopenia with normal mean cell volume: Case series.
The mean red blood cell volume (MCV) is usually increased in severe megaloblastic anemia due to pernicious anemia. However, during one year in a university hospital, three patients with life-threatening pancytopenia and normal MCV were proven to have severe vitamin B12 deficiency. The red blood cell distribution width was markedly increased (three times normal) and led to review of the blood smear and recognition of megaloblastosis as well as prominent red cell fragmentation. These three cases illustrate that vitamin B12 status should be evaluated in cases of pancytopenia, independent of the MCV value.
