Sub Articulo 112.1

How about a \vspace*{2mm} at the beginning of the parbox content?
TeX boxes tend to fit exactly without space. This sometimes is not the
nicest thing especially in tables.  For normal table lines I use
\strut -- if the original is not enough I define one myself like:
\newcommand{\Strut}{\vrule width 0pt height 1.1em depth 0.5em} 
This will make an invisible line of 0pt width but the defined height
and depth according to thedefinition. Since it's defined with "em" it
will scale with the used fontsize.
