Operation Ouch!

Fire in the Lab! (4x7)

:

The doctors find out what happens when you eat with the help of a miniature Xand doll, test your ears and eyes in a baffling mind-bending trick, and join Dr Chris at work fighting infectious diseases. Meanwhile there's an unusual 'itis' in the ouch-mobile, and over in accident and emergency one patient has cut their head and another has a very wonky finger.
