Are you really talking about a menu item or a block here?

If you just want to add a section to the left sidebar that displays 
the results of your query, then in Drupal terms, you need to create a 
"block" in a module, which an administrator can then activate and 
display in the left sidebar on the Blocks admin page. This section of 
the Module Tutorial on drupal.org will get you started with block 

If you need the left sidebar section to appear inside of an existing 
Drupal Menu (Navigation, Primary Links, or another one defined on the 
Menus admin page) that is being displayed on the left sidebar, then I 
think your best bet would be:
a) Add a "dummy" placeholder menu item to the menu, within the admin 
interface, where you want your query results to appear.
b) In your theme, make a custom theme function for theme('menu_item') 
that will detect the dummy item and do your query, and otherwise just 
call theme_menu_item().
There is information on how to override theme functions here:

Good luck!
