Pancreatic islet cell tumor (in fact, in some kids it can exacerbate irritability). You'll want to check out the possibility of a mood disorder (e.g., depressive disorder). One way or the other, a systematic approach to managing the behavior will be crucial. A mental health professional can help you with this, and it would be prudent to schedule an appointment. If you want to read about the sorts of plans I'm suggesting, take a look at Lynn Clark's book titled SOS: Help for Parents, or Ross Green's The Explosive Child (though the latter is not primarily a book about behavior management).
