We performed a prospective study of 1,000 neonates investigated in the first 72 hours of life in the Health Area of Ferrol (northwest of Spain), in order to assess the prevalence of hyperpigmentation of the genital area, the influence of different maternal and neonatal parameters, day of neonatal exploration and type of delivery. Overall frequency of hyperpigmentation was 15.3%. We found a higher prevalence of this dermatosis in non-Caucasian infants (p = 0.000) of male sex (p = 0.000), with Mongolian spot (p = 0.000), vaginal delivery (p = 0.030), maternal age below 30 years (p = 0.006) and at least two previous pregnancies (p = 0.015).

A study of PDMS (polydimethylsiloxane) sol-gel-coated channels fabricated using soft lithography and a laser direct writing technique is presented. PDMS is a biocompatible material that presents a high versatility to reproduce several structures. It is widely employed in the fabrication of preclinical devices due to its advantages but it presents a rapid chemical deterioration to organic solvents. The use of sol-gel layers to cover the PDMS overcomes this problem since it provides the robustness of glass for the structures made with PDMS, decreasing its deterioration and changing the biocompatibility of the surface. In this work, PDMS channels are coated with three different kinds of sol-gel compositions (60MTES/40TEOS, 70MTES/30TISP and 80MTES/20TISP). The endothelial cell adhesion to the different coated devices is evaluated in order to determine the most suitable sol-gel preparation conditions to enhance cellular adhesion. © 2016 by the authors.
