Differences in ebullitive methane release from small, shallow ponds present challenges for scaling.

Small, shallow waterbodies are potentially important sites of greenhouse gas release to the atmosphere. The role of ebullition may be enhanced here relative to larger and deeper systems, due to their shallow water, but these features remain relatively infrequently studied in comparison to larger systems. Herein, we quantify ebullitive release of methane (CH) in small shallow ponds in three regions of North America and investigate the role of potential drivers.

First paediatric case of autochthonous tick-borne encephalitis in the Netherlands, 2018.

Since 2016, sporadic cases of autochthonous tick-borne encephalitis (TBE) have been encountered in the Netherlands, in two distinct geographic regions. We describe the first paediatric autochthonous case of TBE, in 2018, which was contracted outside these regions, suggesting that TBE is more widespread. Countrywide vigilance for new TBE cases remains necessary.

[A long-standing swelling on the shoulder].

We present a 49-year-old woman with a cutaneous horn on the right shoulder since 20 years. Cutaneous horn is a clinical diagnosis referring to a benign or malignant lesion of the skin with a conical projection of cornified material. It is most common on sun-exposed skin.
