    $elementCount=0;
    foreach($html->find('dl.icon a') as $elemen) {
    foreach($elemen->find('dt a') as $element) {
    $elementCount++;
    $element->href = "http://www.usmleforum.com" . $element->href; 
    echo '<li target="_blank" class="itemtitle">';
    if($elementCount < 5 && $elementCount > 2 && rand(0,1) == 1) {
     echo '<span class="item_new">new</span>';
}
    echo $element;
    echo '</li>';

There is no DOM element like dl.icon a dt a. You probably want to fetch dl.icon dt a. Remove a from first argument in find method.

Always try to debug your code before asking questions. Simple echo "A"; die(); echo "B"; die(); after every statement will be very helpfull :)

In this case second foreach have 0 elements all the time.
