[Cervicofacial emphysema and pneumomediastinum after dental treatment].

Pneumomediastinum with subcutaneous emphysema is a rarely observed complication of dental treatment. It is a potentially dangerous condition, but the majority of cases are self-limiting and benign. We present a case of pneumomediastinum and cervicofacial emphysema that occurred after dental treatment.

Gastroenteritis and the novel picornaviruses aichi virus, cosavirus, saffold virus, and salivirus in young children.

Background: During the last few years many new human picornaviruses have been discovered due to advances in metagenomics and other molecular biological approaches. The clinical significance and the occurrence are only sparsely described.

Objectives: To determine the epidemiology and clinical significance of infections with the novel human picornaviruses, aichi virus, cosavirus, salivirus, and saffold virus in infants in Denmark.
