Human primary immunodeficiencies (PIDs) are often thought to be confined to a few rare, familial, monogenic, recessive traits impairing the development or function of one or several leucocyte subsets and resulting in multiple, recurrent, opportunistic and fatal infections in infancy. We highlight here the rapidly growing number of exceptions to each of these conventional qualifications. ⋯ We need to increase awareness of the multitude of clinical presentations of human PIDs considerably and rapidly in the medical community. Human PIDs should be considered in a wide range of clinical situations.

Multicenter Study
High D-dimer levels increase the likelihood of pulmonary embolism.
Objective. To determine the utility of high quantitative D-dimer levels in the diagnosis of pulmonary embolism. Methods. ⋯ Conclusion. Strongly elevated D-dimer levels substantially increase the likelihood of pulmonary embolism. Whether this should translate into more intensive diagnostic and therapeutic measures in patients with high D-dimer levels irrespective of CDR remains to be studied.

Randomized Controlled Trial
Use of B-type natriuretic peptide in the risk stratification of community-acquired pneumonia.
Community-acquired pneumonia (CAP) is the leading infectious cause of death in developed countries. Risk stratification has previously been difficult. ⋯ In patients with CAP, BNP levels are powerful and independent predictors of death and treatment failure. When used in conjunction with the PSI, BNP levels significantly improve the risk prediction when compared with the PSI alone.

The scientific evidence on whether long-term use of snuff is associated with high blood pressure is limited, inconsistent and based only on cross-sectional data. ⋯ Use of Swedish moist snuff appears to be associated with a moderately increased risk of hypertension.
