Subgaleal hemorrhage in neonates: a comprehensive review and summary recommendations.

Subgaleal hemorrhages (SH) involve bleeding in the expansive compartment between the periosteum of the skull and the galea aponeurotica. The potentially rapid accumulation of blood in this space is responsible for the clinical severity, as neonates with SH can present with acute hypovolemia, shock and multiorgan failure. SH is associated with instrumented delivery, especially with use of vacuum extraction.

Quantification of anion and cation uptake in ice Ih crystals.

While ice has very low solubility for salts compared to water, small amounts of ions are doped into ice crystals. These small ion dopants can alter the fundamental physical and chemical properties of ice, such as its structure and electrical conductivity. Therefore, these results could have a direct impact on the chemical reactivity of ice and ice surfaces.
