A page break directly after a first item of a itemize oder enumerate environment or other lists may be annoying. How to prevent that? A common way to prevent a page break is to use a minipage (or samepage) environment, but you cannot use that for just a part of the list.
The needspace package allows to define how much vertical space is needed. If there is enough space it continues normally, but if the space left on the page is less than requested a page break is inserted. The documentation of needspace is inside the sty-file itself. Her is an example:

\usepackage{needspace}
...
\needspace{5\baselineskip}
Remarks:
  \begin{itemize}
    \item ...
...

Then immediately after Remarks: no pagebreak could happen.
