0:00:22 > 0:00:24He's Dr Chris.
0:00:24 > 0:00:26And he's Dr Xand.
0:00:26 > 0:00:28Yes, he's still got his beard.
0:00:28 > 0:00:30And we're still identical twins.
0:00:30 > 0:00:33Your body is amazing and we're going to show you why.
0:00:36 > 0:00:38We're head-to-head in Operation Takeover.
0:00:38 > 0:00:39- BOTH:- Man overboard.
0:00:41 > 0:00:43Ouch And About hits the wards.
0:00:43 > 0:00:45What kind of ambulance did you get?
0:00:45 > 0:00:47I didn't get an ambulance, I got a helicopter.
0:00:47 > 0:00:48First Aid is back.
0:00:48 > 0:00:50We do need to get Xand to hospital.
0:00:50 > 0:00:52Meet our new brilliant Ouch patients...
0:00:52 > 0:00:54I'm off to my physio appointment.
0:00:54 > 0:00:57..and our lab experiments... DR XAND SCREAMS
0:00:57 > 0:00:58..will blow...
0:00:58 > 0:01:00..your...
0:01:00 > 0:01:02- ..mind! - That is an amazing view.
0:01:02 > 0:01:03Are you ready to join us?
0:01:06 > 0:01:08I can't see a thing.
0:01:09 > 0:01:12- Coming up today on... - Super Xand!
0:01:12 > 0:01:13..Operation Ouch!
0:01:16 > 0:01:18We're all a-splutter in the lab.
0:01:18 > 0:01:20- There we go.- We're sniffing out medical mysteries.
0:01:20 > 0:01:23That might be the squishiest nose I've ever seen.
0:01:23 > 0:01:25And things get tasty.
0:01:25 > 0:01:28- Is that all right?- It would be helpful if you kept it in the bowl.
0:01:28 > 0:01:30But first...
0:01:30 > 0:01:33INDISTINCTLY: Medical teams are always at the ready.
0:01:33 > 0:01:35Xand, the sweet, please.
0:01:35 > 0:01:38And the other one. OK, now continue.
0:01:38 > 0:01:41Medical teams are already at the ready.
0:01:41 > 0:01:43Let's see who the first case in A&E is.
0:01:43 > 0:01:44Can I have my sweet back?
0:01:44 > 0:01:45No.
0:01:47 > 0:01:50Six-year-old Winnie is waiting to see the doctor with her mum
0:01:50 > 0:01:52in the children's emergency department.
0:01:52 > 0:01:54Look, poor Winnie has a sling.
0:01:54 > 0:01:56I've got a sore arm.
0:01:56 > 0:01:58Winnie walks with a walking frame,
0:01:58 > 0:02:00so I saw her wobble and then topple over.
0:02:00 > 0:02:02So that's why I'm a bit worried it might be fractured.
0:02:02 > 0:02:05Oh, no, how did it happen?
0:02:05 > 0:02:08Winnie was at her favourite after-school activity.
0:02:08 > 0:02:12- And what's that?- Well, she does lots of activities like dance, swimming,
0:02:12 > 0:02:14tennis, cheerleading.
0:02:14 > 0:02:17Wow! So she was dancing in the swimming pool with a tennis racket
0:02:17 > 0:02:20- while cheerleading?- No, Xand.
0:02:20 > 0:02:24Winnie's absolute favourite thing to do is play over at her best mate's
0:02:24 > 0:02:26- Sophie's house.- It looks fun.
0:02:26 > 0:02:29Yes, but as they were playing catch in the garden,
0:02:29 > 0:02:31Winnie slipped on the wet grass,
0:02:31 > 0:02:34trapping her arm underneath her walking frame.
0:02:34 > 0:02:35- BOTH:- Ouch!
0:02:37 > 0:02:42Oh, dear. Let's hope Dr Ashley Timings-Thompson can get you sorted.
0:02:42 > 0:02:45First, the doc checks the nerves in Winnie's arm by making sure she can
0:02:45 > 0:02:48- feel properly.- We need to play a game, OK?
0:02:48 > 0:02:49Ooh, I love a game.
0:02:49 > 0:02:52What you need to do is close your eyes really tight.
0:02:52 > 0:02:53No peeping!
0:02:53 > 0:02:56And then when I touch you on your arm, just say yes.
0:02:56 > 0:02:58- Yes.- Very good.
0:02:58 > 0:03:00- Yes.- Well done.
0:03:00 > 0:03:01- Yes.- Very good.
0:03:01 > 0:03:03Winnie wins. Time to check her movement.
0:03:03 > 0:03:05Is that sore?
0:03:05 > 0:03:08I think you might have broken a bone in your elbow, OK?
0:03:08 > 0:03:10So what we need to do is get an X-ray.
0:03:10 > 0:03:13I like having X-rays.
0:03:13 > 0:03:15Do you?
0:03:15 > 0:03:20It's like a computer above you taking a picture inside
0:03:20 > 0:03:24and when you look at it, it's very interesting.
0:03:24 > 0:03:26Well, you're in luck today.
0:03:26 > 0:03:29You're getting two X-rays from different angles.
0:03:29 > 0:03:31Good girl, you're all finished.
0:03:31 > 0:03:33And then it's straight to the doc for the results.
0:03:33 > 0:03:34Looking at your X-ray,
0:03:34 > 0:03:38I just wonder if you've got a very small break in this part
0:03:38 > 0:03:41of your bone here. So what we're going to do is put your hand
0:03:41 > 0:03:44in what we call a collar and cuff just to keep it steady overnight
0:03:44 > 0:03:46and then we'll bring you back tomorrow,
0:03:46 > 0:03:48- see how you're getting on.- OK.
0:03:48 > 0:03:51Winnie needs to see an orthopaedic surgeon -
0:03:51 > 0:03:53a doctor who specialises in bones.
0:03:53 > 0:03:58Tomorrow, I'm going to come back to see if I need
0:03:58 > 0:04:01any further treatment.
0:04:01 > 0:04:04OK, Winnie. We'll be back to find out how you get on.
0:04:09 > 0:04:11And now to our lab.
0:04:11 > 0:04:14It's time for some big body experiments.
0:04:14 > 0:04:15Some of them gory.
0:04:15 > 0:04:17This is not for the squeamish.
0:04:17 > 0:04:19Some extreme.
0:04:19 > 0:04:20It's freezing!
0:04:20 > 0:04:22We're ready. Are you?
0:04:24 > 0:04:26Just don't try anything you see here at home.
0:04:27 > 0:04:31Today we're looking at why we cough and the part of your body that makes
0:04:31 > 0:04:33- it happen.- Xand, what are you doing?
0:04:34 > 0:04:36This is a lab, not a laundry.
0:04:36 > 0:04:39- I know, but...- There is a time and a place to do your dirty washing
0:04:39 > 0:04:43and this isn't it because today we're going to look at one of the
0:04:43 > 0:04:46biggest organs in your body. The organ involved in coughing.
0:04:46 > 0:04:48- Yes, it's...- Your lungs!
0:04:49 > 0:04:51That's what all this is for, Chris.
0:04:51 > 0:04:53If you laid your lungs out flat,
0:04:53 > 0:04:55opened up all the little spaces inside them,
0:04:55 > 0:04:57they'd be about 50 square metres.
0:04:57 > 0:04:59That's huge.
0:04:59 > 0:05:02That's the same as all this material around the lab.
0:05:02 > 0:05:05That's right. Your lungs have a huge surface area,
0:05:05 > 0:05:08but to understand how you can fit it inside your chest,
0:05:08 > 0:05:10come and take a look at this.
0:05:10 > 0:05:13Here comes a Gross Alert.
0:05:13 > 0:05:15This is a real pair of cow's lungs.
0:05:15 > 0:05:19Now people often think that lungs are a bit like empty bags
0:05:19 > 0:05:22full of air, but in fact, they're solid
0:05:22 > 0:05:25so you can see here a cross-section through the lung.
0:05:25 > 0:05:30Now these tubes are the large airways that take air down to the
0:05:30 > 0:05:34segments and the segments look like they're made of foam and that's
0:05:34 > 0:05:37because the segments are full of tiny little air sacs
0:05:37 > 0:05:39called alveoli.
0:05:39 > 0:05:42In humans, alveoli are far too small to be seen.
0:05:42 > 0:05:45But you can see them in these massive cow's lungs.
0:05:45 > 0:05:48They pass oxygen from the air into your blood to be used by your body.
0:05:50 > 0:05:54With every breath you take, you inhale air, also viruses,
0:05:54 > 0:05:56pollen dust and bacteria.
0:05:56 > 0:05:59But don't worry, your lungs have an amazing trick to get rid of stuff
0:05:59 > 0:06:01that you inhale that you don't want.
0:06:01 > 0:06:03- Coughing. - XAND COUGHS
0:06:03 > 0:06:06Exactly. And we're going to show you how it works.
0:06:09 > 0:06:13Coughing is a really clever technique that your body uses
0:06:13 > 0:06:15to get rid of anything unwanted from inside your lungs,
0:06:15 > 0:06:18including the large amounts of mucus
0:06:18 > 0:06:20produced when you're ill with a chest infection.
0:06:20 > 0:06:22To show you how coughing works,
0:06:22 > 0:06:26we're going to inflate this pair of healthy lungs using gas from this
0:06:26 > 0:06:28canister. Xand, inflate the lungs.
0:06:32 > 0:06:34This is awesome.
0:06:34 > 0:06:35We've never done this before.
0:06:35 > 0:06:40Even at medical school we never saw lungs inflated outside of a body.
0:06:40 > 0:06:42So here, where the lung's gone white,
0:06:42 > 0:06:44these alveoli are fully inflated.
0:06:44 > 0:06:48Wow! This is one of my favourite experiments ever, I think.
0:06:48 > 0:06:52These lungs are a lot like your lungs, but a bit bigger.
0:06:52 > 0:06:54They are actually about six times bigger.
0:06:56 > 0:06:59All right, Xand, turn off the gas and let's breathe out.
0:07:04 > 0:07:06And now the lungs are deflated.
0:07:06 > 0:07:08Now to show you the importance of coughing,
0:07:08 > 0:07:10we need to infect one of these lungs.
0:07:10 > 0:07:11So I'm going to put some mucus into it.
0:07:11 > 0:07:15This is like what happens if you have a very serious chest infection.
0:07:15 > 0:07:18I'm going to insert some fake mucus into the lung.
0:07:18 > 0:07:22Now, look what happens when Xand turns on the gas.
0:07:22 > 0:07:25The mucus-infected lung doesn't inflate properly any more
0:07:25 > 0:07:27because it's blocked.
0:07:27 > 0:07:31And this shows you the importance of coughing for getting mucus
0:07:31 > 0:07:34out of your lungs so those airways don't get clogged up.
0:07:34 > 0:07:37And to demonstrate coughing, I've got some balloons over here.
0:07:38 > 0:07:40I have here, two balloons.
0:07:40 > 0:07:43Now, mine is a nice, healthy, mucus-free balloon.
0:07:43 > 0:07:46Xand, I'm afraid yours is very badly infected.
0:07:46 > 0:07:48As you can see from the large amount of mucus in the airway.
0:07:48 > 0:07:50Eurgh!
0:07:50 > 0:07:51Now let's inflate the balloons.
0:07:51 > 0:07:53Three, two, one.
0:07:56 > 0:07:57This doesn't feel fair, Chris.
0:07:57 > 0:08:00My mucus-filled balloon is really hard to blow up.
0:08:03 > 0:08:06You can see my balloon inflates extremely easily and also...
0:08:08 > 0:08:10..deflates extremely easily.
0:08:10 > 0:08:13- How is it going, Xand?- Very badly.
0:08:13 > 0:08:16I've got a mouthful of mucus and I can barely get any air
0:08:16 > 0:08:18into this lung.
0:08:18 > 0:08:20Seems to me, Xand, that you should have a bit of a cough.
0:08:20 > 0:08:22Ooh, that'd make me feel much better.
0:08:22 > 0:08:25OK, ready? Three, two, one.
0:08:27 > 0:08:29There we go.
0:08:30 > 0:08:33When you cough, all the muscles around your chest and abdomen
0:08:33 > 0:08:37contract suddenly. This creates enough force to eject the mucus
0:08:37 > 0:08:39up your trachea and out of your mouth
0:08:39 > 0:08:42like the mucus coming out of this balloon.
0:08:42 > 0:08:46Now that has nicely cleared the mucus from Xand's airways
0:08:46 > 0:08:48and now his lungs are clear again.
0:08:49 > 0:08:52So, that's why you cough when you have a chest infection.
0:08:52 > 0:08:55We've shown you just how important the alveoli are in your lungs
0:08:55 > 0:08:57and how they help you breathe easily.
0:08:58 > 0:09:01And we've shown you that when they get clogged up with mucus, you can't
0:09:01 > 0:09:04inflate your lungs properly so you have to cough.
0:09:04 > 0:09:08Plus, it was a great excuse to cover Xand in gunk.
0:09:08 > 0:09:12Well, I must say, Chris, after that cough, I feel a lot better.
0:09:12 > 0:09:14I'm off to play footie in the park.
0:09:14 > 0:09:16But what about this mucus on the floor?
0:09:16 > 0:09:18Who is going to help me tidy this up?
0:09:18 > 0:09:20- Xand?- It was your experiment.
0:09:25 > 0:09:26We're both...
0:09:26 > 0:09:27- BOTH:- Ouch And About!
0:09:27 > 0:09:30I'm hitting the wards with my Ouch bleeper.
0:09:30 > 0:09:32Have you got a question for me?
0:09:32 > 0:09:33Wow.
0:09:33 > 0:09:36And I'm hitting the streets to answer your medical mysteries.
0:09:38 > 0:09:40Xand's in the hospital canteen,
0:09:40 > 0:09:42but there's no time for snacking.
0:09:42 > 0:09:44Huh?
0:09:44 > 0:09:45It's bleeper o'clock.
0:09:45 > 0:09:46Ooh!
0:09:46 > 0:09:49It's from Ruth who's had an ankle operation.
0:09:49 > 0:09:51- Hello, Ruth.- Hello.
0:09:51 > 0:09:53- Have you got a question for me? - Yeah.
0:09:53 > 0:09:54Why do I got a squishy nose?
0:09:54 > 0:09:56What's the diagnosis, doc?
0:09:56 > 0:09:57Sounds like a case of...
0:10:00 > 0:10:02Let's see if you NOSE the answer.
0:10:02 > 0:10:04Now, Ruth, how squishy is your nose?
0:10:04 > 0:10:07That might be the squishiest nose I've ever seen.
0:10:07 > 0:10:09Everyone's nose is a bit squishy, isn't it?
0:10:09 > 0:10:12Because your nose is mostly made of cartilage,
0:10:12 > 0:10:13and cartilage is rubbery,
0:10:13 > 0:10:16but most people's cartilage is quite tough, whereas yours is really,
0:10:16 > 0:10:18really flexible, isn't it?
0:10:18 > 0:10:21- Yeah.- You've got a squishy nose for the same reason you've got a
0:10:21 > 0:10:23problem with your ankle, haven't you?
0:10:23 > 0:10:25What's the main thing you've got?
0:10:27 > 0:10:29Larsen syndrome means that some of her tissues,
0:10:29 > 0:10:32her connective tissues and her bones don't quite grow the same as other
0:10:32 > 0:10:35people's. Have you got some other problems with bones as well?
0:10:35 > 0:10:37- Yeah.- Wow.
0:10:37 > 0:10:40So, what Ruth is doing there is dislocating her knee.
0:10:40 > 0:10:43Her knee is actually popping out of joint, cos you've got very stretchy
0:10:43 > 0:10:46ligaments around your knee and the muscles are a bit looser.
0:10:46 > 0:10:49You can just pop your knee out of joint and then pop it back in again.
0:10:49 > 0:10:51- And does that hurt at all?- No. - DR XAND LAUGHS
0:10:51 > 0:10:52Well, thank you very much.
0:10:52 > 0:10:56I think you deserve an Operation Ouch! sticker.
0:10:56 > 0:10:57- Bye.- Bye.
0:10:59 > 0:11:01Meanwhile, I'm out on the street.
0:11:01 > 0:11:05Does anyone have any medical mysteries for me?
0:11:05 > 0:11:07Oh, hello. What's your question?
0:11:09 > 0:11:11So, first of all, show me the teeth you lost.
0:11:11 > 0:11:13Oh, wow, those two bottom ones.
0:11:13 > 0:11:16- Yeah.- Do you know what those two teeth were called?- Um...
0:11:16 > 0:11:18They are called incisors.
0:11:18 > 0:11:21You lost your bottom two incisors. And the reason you lost them
0:11:21 > 0:11:25is because when you're born, you have your grown-up teeth up here
0:11:25 > 0:11:27in your maxilla which is a bone of the skull
0:11:27 > 0:11:30and you have your grown-up teeth down here in your mandible
0:11:30 > 0:11:33which is your jaw bone, and as the grown-up teeth start to come
0:11:33 > 0:11:35through, they push out the baby teeth.
0:11:35 > 0:11:36So, it's nothing to worry about.
0:11:36 > 0:11:39Losing baby teeth is completely normal and because you asked such
0:11:39 > 0:11:42a great question, I'm going to give you an Operation Ouch! sticker.
0:11:42 > 0:11:43- There you go.- Thank you.
0:11:43 > 0:11:45Another happy customer.
0:11:45 > 0:11:48Back in the hospital, I've had another call.
0:11:48 > 0:11:50It's from Shaun who has cancer.
0:11:50 > 0:11:51Hello, Shaun. How are you?
0:11:51 > 0:11:53I'm good, thanks, Dr Xand.
0:11:53 > 0:11:54Now, have you got a question for me?
0:11:54 > 0:11:56Yeah. How does cancer form?
0:11:56 > 0:11:58What's the diagnosis, doc?
0:11:58 > 0:12:00It sounds to me like a case of...
0:12:02 > 0:12:04Now, that's a tricky question.
0:12:04 > 0:12:07Cancer is when your body's cells keep dividing.
0:12:07 > 0:12:09They divide too much.
0:12:09 > 0:12:13So, somewhere in your body, one cell had a genetic mutation -
0:12:13 > 0:12:17a bit of its DNA went wrong and the gene that stopped it dividing
0:12:17 > 0:12:20too many times got switched off or got damaged somehow
0:12:20 > 0:12:23and so it started making more and more and more of them.
0:12:23 > 0:12:25So, what kind of cancer have you got, Shaun?
0:12:28 > 0:12:31- Acute lymphoblastic leukaemia.- Yeah.
0:12:31 > 0:12:35So leukaemia is a kind of cancer of your blood cells and Shaun's
0:12:35 > 0:12:39particular kind of cancer is a white blood cell cancer so you effectively
0:12:39 > 0:12:41have too many white blood cells.
0:12:41 > 0:12:43Now, white blood cells are really useful. They fight infection.
0:12:43 > 0:12:45The problem is,
0:12:45 > 0:12:48if you're making too many white blood cells it crowds out the other
0:12:48 > 0:12:51kinds of cells you need. What kind of treatment are you having, Shaun?
0:12:51 > 0:12:55- Chemotherapy.- So, the reason you're having the chemotherapy
0:12:55 > 0:12:57is to kind of reset those genes.
0:12:57 > 0:12:59Shaun, have I answered your question?
0:12:59 > 0:13:01- Yeah, thanks.- Here is an Operation Ouch! sticker.
0:13:01 > 0:13:02Thanks, doctor.
0:13:02 > 0:13:04- Bye.- Bye.
0:13:04 > 0:13:05Job done for today.
0:13:11 > 0:13:13Earlier, Winnie came into the emergency department
0:13:13 > 0:13:16- with a sore arm.- Well, let's find out how she's getting on.
0:13:16 > 0:13:18- Come on.- Come on.
0:13:18 > 0:13:19- Come on.- Come on.- Let's go!
0:13:19 > 0:13:21Now!
0:13:21 > 0:13:25Winnie had to have her arm put in a sling after an accident.
0:13:25 > 0:13:27She'd been playing catch with her friend Sophie,
0:13:27 > 0:13:30but she slipped and her arm was trapped underneath
0:13:30 > 0:13:31her walking frame.
0:13:31 > 0:13:33- BOTH:- Ouch!
0:13:33 > 0:13:37Winnie's X-ray showed she might have a small break on her elbow.
0:13:37 > 0:13:39My arm is stinging.
0:13:39 > 0:13:42Don't worry, you're back to see an orthopaedic doctor
0:13:42 > 0:13:45who specialises in bones.
0:13:45 > 0:13:47Here is Dr Janet Cumberland.
0:13:47 > 0:13:49Does it hurt when I press on there?
0:13:49 > 0:13:53- A bit. - OK. Can you straighten it out?
0:13:55 > 0:13:56That's fantastic.
0:13:56 > 0:13:58I think your arm is OK.
0:13:58 > 0:13:59Brilliant news.
0:13:59 > 0:14:03For her to be this comfortable only the next day,
0:14:03 > 0:14:05I'm very happy she hasn't broken anything.
0:14:05 > 0:14:08When they looked at the X-ray in A&E,
0:14:08 > 0:14:10they could see this little irregularity
0:14:10 > 0:14:13on the surface of the bone
0:14:13 > 0:14:15and they wondered if that might be a break.
0:14:15 > 0:14:18Lots of bones can have little bits of irregularity in them.
0:14:18 > 0:14:21That's just normal for the patient.
0:14:21 > 0:14:24Fabulous. So you can carry on doing dancing and cheerleading.
0:14:24 > 0:14:26Yeah.
0:14:26 > 0:14:28Yes, Mum, but Winnie still needs to take care.
0:14:28 > 0:14:32She's damaged the soft tissue around her elbow which can take up to six
0:14:32 > 0:14:34weeks to heal.
0:14:34 > 0:14:36I'm feeling very happy.
0:14:36 > 0:14:39Any advice for me and Chris when we're playing catch?
0:14:39 > 0:14:42Not to go on the grass when it's slippy.
0:14:42 > 0:14:44Got it.
0:14:44 > 0:14:46- BOTH:- Bye, Winnie.
0:14:46 > 0:14:48Still to come...
0:14:48 > 0:14:50We're looking dishy.
0:14:50 > 0:14:53There is an unidentified object.
0:14:53 > 0:14:54Whoa!
0:14:54 > 0:14:55And we work out who done it?
0:14:55 > 0:14:57What on earth has happened here?
0:14:57 > 0:14:59But first,
0:14:59 > 0:15:05did you know that the loudest burp ever recorded was over 100 decibels?
0:15:05 > 0:15:07LOUD BURPING
0:15:07 > 0:15:09That's louder than a tractor.
0:15:09 > 0:15:11Wow! XAND BURPS
0:15:11 > 0:15:13- Excuse me.- Xand!
0:15:16 > 0:15:20Amazing people do lots of important jobs inside and outside hospitals
0:15:20 > 0:15:25that help to keep you safe. But what will happen when we have a go?
0:15:25 > 0:15:26I feel a bit silly.
0:15:26 > 0:15:27This is...
0:15:29 > 0:15:32Can you guess who today's Hospital Hero is?
0:15:32 > 0:15:33Well, I'll give you a clue.
0:15:33 > 0:15:35You might see them when your tummy is doing this.
0:15:35 > 0:15:37TUMMY RUMBLES
0:15:37 > 0:15:38They might wear one of these
0:15:38 > 0:15:41and they work with lots and lots of this.
0:15:41 > 0:15:42Food!
0:15:42 > 0:15:46Chris, this is going to be the best Hospital Takeover Challenge yet!
0:15:46 > 0:15:50I mean, who can complain about having to eat all this yummy...?
0:15:50 > 0:15:52- Xand! We're not here to eat. - Aren't we?
0:15:52 > 0:15:56We're here to find out about the amazing people that work
0:15:56 > 0:15:59- in the hospital canteen.- Oh, yeah.
0:15:59 > 0:16:02We're about to take over the job of today's heroes -
0:16:02 > 0:16:05executive chef Simon and restaurant supervisor Donna.
0:16:06 > 0:16:10They're on the front line at Alder Hey Hospital restaurant
0:16:10 > 0:16:14where they serve around 500 meals a day to patients, their families
0:16:14 > 0:16:15and staff.
0:16:15 > 0:16:16Pleasure.
0:16:16 > 0:16:19This is different to a normal restaurant in that people who
0:16:19 > 0:16:21are in a hospital usually have something to worry about
0:16:21 > 0:16:24or some problem, that's why they've come.
0:16:24 > 0:16:26Sometimes parents are looking to get away from the bed side.
0:16:26 > 0:16:30In the restaurant, it's a friendly face for them to speak to.
0:16:30 > 0:16:31And what about the serving food?
0:16:31 > 0:16:33Do you get any tricky situations there?
0:16:33 > 0:16:35Yeah. Some people have allergies.
0:16:35 > 0:16:38It could be a life or death situation with the allergy.
0:16:38 > 0:16:40- So the stakes are quite high. - STEAKS are high.
0:16:40 > 0:16:42- That was good.- That was good.
0:16:42 > 0:16:44To find out what makes a good canteen worker,
0:16:44 > 0:16:46we need to talk to some customers.
0:16:46 > 0:16:49So, Ruby, you've been coming to the Alder Hey canteen
0:16:49 > 0:16:50- for how many years now?- Eight.
0:16:50 > 0:16:53So you know this canteen pretty well.
0:16:53 > 0:16:56Yeah. I think it's nice that they want to know about me and make me
0:16:56 > 0:16:58feel a bit better.
0:16:58 > 0:16:59Kera, have you got any tips?
0:16:59 > 0:17:02You've got to be nice to the people.
0:17:02 > 0:17:04What do you think would be the worst thing that we could do?
0:17:04 > 0:17:06Maybe set the place on the fire.
0:17:06 > 0:17:08Who do you think is more likely to do this, me or Chris?
0:17:08 > 0:17:11- You.- What? - Because you're more crazy.
0:17:12 > 0:17:13Thanks, Ruby and Kera.
0:17:13 > 0:17:16We've learned just how important the hospital canteen is for patients
0:17:16 > 0:17:19- and their families.- But will our attempts to be hospital servers
0:17:19 > 0:17:22go as well as fish goes with chips
0:17:22 > 0:17:25or will we make a real dog's dinner out of it?
0:17:25 > 0:17:27Get it? Good, eh? DOGS BARK
0:17:27 > 0:17:28Get it?
0:17:31 > 0:17:34It's time for us to take over as canteen workers.
0:17:35 > 0:17:38Your Takeover Challenge today is you're going to serve the special,
0:17:38 > 0:17:40which is a hot salad with chicken and bacon.
0:17:40 > 0:17:41Sounds like a piece of cake.
0:17:41 > 0:17:43No, it's a hot chicken and bacon salad.
0:17:43 > 0:17:45Oh.
0:17:45 > 0:17:46There we go.
0:17:46 > 0:17:49First, Simon gives us a quick demonstration on the best way
0:17:49 > 0:17:50to serve our salads.
0:17:51 > 0:17:53Put in six pieces of chicken.
0:17:53 > 0:17:54We're going to be judged on...
0:17:59 > 0:18:01Don't forget to ask about allergies.
0:18:01 > 0:18:05The two allergens that we have in this meal here is, we have mustard
0:18:05 > 0:18:09in the dressing and we have gluten in the croutons.
0:18:09 > 0:18:10- OK. Cool.- How is that?
0:18:10 > 0:18:11That looks fantastic.
0:18:11 > 0:18:14Donna and Simon will be checking our every move.
0:18:14 > 0:18:17The key to a good hot salad, Chris, is showmanship.
0:18:17 > 0:18:20People want flair, excitement, speed.
0:18:20 > 0:18:22I might try and set it on fire.
0:18:22 > 0:18:24Xand, the key to a good salad is hygiene.
0:18:24 > 0:18:26Get your finger out of your ear.
0:18:26 > 0:18:27Disgusting.
0:18:27 > 0:18:29Xand's up first.
0:18:29 > 0:18:31- How are you doing today? - Very well, thank you.
0:18:31 > 0:18:33- And who are you with? - This is my son, William.
0:18:33 > 0:18:36Hey, William. Are you allergic to anything?
0:18:36 > 0:18:38- No.- Good communication, Xand.
0:18:38 > 0:18:40You remembered the allergies.
0:18:40 > 0:18:41SHE LAUGHS
0:18:41 > 0:18:43How does it look, William? Does it look edible?
0:18:43 > 0:18:45That's great, thank you very much.
0:18:45 > 0:18:47- You've done a good job. - Done very well.
0:18:47 > 0:18:49That was his first salad. The portion size was slightly out.
0:18:49 > 0:18:51Look, I hope your lad does well with his operation.
0:18:51 > 0:18:54- I'm sure he will. - Xand is speeding through it.
0:18:54 > 0:18:57He has done it really fast. Really well. It looks good.
0:18:57 > 0:18:59And really filling, so I'm happy with it.
0:18:59 > 0:19:01Here we go, right. How am I doing tossing the salad?
0:19:01 > 0:19:04- Is that all right?- It would be helpful if you kept it in the bowl.
0:19:04 > 0:19:07Oh, dear. I'm sure I'll do better than that.
0:19:08 > 0:19:10Go on, then, Chris, it's your turn.
0:19:10 > 0:19:12Do you have any allergies?
0:19:12 > 0:19:13- No.- No.
0:19:13 > 0:19:15Great communication, Chris.
0:19:15 > 0:19:18A bit of tomato. A bit of this lettuce, cucumber.
0:19:18 > 0:19:20He's doing fine. He's picking it up,
0:19:20 > 0:19:23- but he's doing a little bit too much chatting.- She's got a point.
0:19:23 > 0:19:26We can give six pieces of chicken. One, two, three...
0:19:26 > 0:19:28Speed up, we haven't got all day.
0:19:28 > 0:19:30Have you got any allergies?
0:19:30 > 0:19:31None I know of.
0:19:31 > 0:19:34Lots of onion? Got no meetings this afternoon?
0:19:34 > 0:19:36Just a few!
0:19:36 > 0:19:38Uh-oh, time's up.
0:19:38 > 0:19:41- There was a spare one. - Put the food down, Xand.
0:19:42 > 0:19:45We're ready for the verdict.
0:19:45 > 0:19:47I think overall you both did very, very well.
0:19:47 > 0:19:51Portion size - Xand you wasn't as good on the portion size.
0:19:51 > 0:19:54The reason being is when you started to shake your salad, a little bit
0:19:54 > 0:19:56landed on the floor. It was like he was doing a dance
0:19:56 > 0:19:58- behind the counter.- I wanted to put on a bit of a show, to be honest.
0:19:58 > 0:20:01People don't want shows, Xand, they want salad.
0:20:01 > 0:20:05Speed-wise, unfortunately, Chris, you were quite slow.
0:20:05 > 0:20:07But one person done too much chatting.
0:20:10 > 0:20:11And the winner of the challenge is...
0:20:16 > 0:20:19For Simon, it's a draw, but the clear winner for Donna is Dr Xand.
0:20:21 > 0:20:24Well done, Xand, on a narrow victory,
0:20:24 > 0:20:27but I think what we both learned today is just what an important job
0:20:27 > 0:20:29the hospital catering department does.
0:20:29 > 0:20:32I think to be honest we should leave it to the professionals.
0:20:32 > 0:20:34Thank you very much.
0:20:34 > 0:20:36I wonder if there is any salad left?
0:20:40 > 0:20:41Xand, I'm home.
0:20:41 > 0:20:45Ooh! Ah, Chris, just, er, hang on a minute.
0:20:45 > 0:20:46Xand!
0:20:46 > 0:20:48DRAMATIC MUSIC
0:20:48 > 0:20:49What on earth has happened here?
0:20:49 > 0:20:52Ah, well, the thing is...
0:20:52 > 0:20:55That's my Doctor of the Year award.
0:20:55 > 0:20:56How did it get broken?
0:20:56 > 0:20:58- Was this you?- No.
0:20:58 > 0:21:01Unless we were broken into, I cannot see an explanation.
0:21:01 > 0:21:02That's the explanation.
0:21:02 > 0:21:05I came in myself and someone barged past me
0:21:05 > 0:21:09- and kind of pushed me out of the way.- Xand, that's terrible.
0:21:09 > 0:21:12- Did you get hurt?- No, I've got a little bruise on my arm.
0:21:12 > 0:21:13It's nothing really.
0:21:13 > 0:21:16This is a case for Investigation Ouch!
0:21:21 > 0:21:24We need to take photos of absolutely everything.
0:21:28 > 0:21:32That bruise looks awful and how did that cut happen?
0:21:32 > 0:21:33Sorry, Chris, I've got to go.
0:21:34 > 0:21:37Don't worry, Xand, I've got just the person to help me solve it.
0:21:37 > 0:21:42This is forensics expert Professor Peter Vanezis.
0:21:42 > 0:21:44He's an expert in medical evidence.
0:21:44 > 0:21:46He sifts through clues at crime scenes
0:21:46 > 0:21:48to help the police solve cases.
0:21:48 > 0:21:51This is called forensics.
0:21:51 > 0:21:54Today, he's helping me find out who hurt Xand and who broke
0:21:54 > 0:21:56my Doctor of the Year award.
0:21:56 > 0:21:58So what should we start by looking for?
0:21:58 > 0:22:01Well, obviously look at the glass to see if there are any fingerprints.
0:22:01 > 0:22:03It looks like also there's a little bit of blood on the glass
0:22:03 > 0:22:05which was shattered.
0:22:05 > 0:22:07This is a special aluminium powder
0:22:07 > 0:22:10which will make any fingerprints stand out.
0:22:10 > 0:22:11Ooh, I found one.
0:22:11 > 0:22:15Why do fingers leave a mark behind on surfaces?
0:22:15 > 0:22:18Fingerprints actually consist of the secretions from the glands in your
0:22:18 > 0:22:22skin. It's that sweaty material which is left behind on the surface
0:22:22 > 0:22:24and you can pick it up by dusting.
0:22:24 > 0:22:27Everybody's fingerprints are different. Even identical twins.
0:22:27 > 0:22:32If I find Dr Xand's fingerprints, does that close the case on him?
0:22:32 > 0:22:36- It certainly doesn't, no.- But he knows he is not allowed to touch my
0:22:36 > 0:22:38- award. - Well, does he do what he's told?
0:22:38 > 0:22:39Almost never.
0:22:39 > 0:22:42It's time to move on to my evidence board.
0:22:44 > 0:22:47Xand said he got it eight hours ago buttering toast,
0:22:47 > 0:22:50but there was blood on the award. What does our expert think?
0:22:51 > 0:22:54A butter knife is not the kind of knife that you would actually cause
0:22:54 > 0:22:57a cut like that. The important thing is it is fresh.
0:22:57 > 0:22:59There is no evidence of any drying of the blood at all.
0:22:59 > 0:23:02So it's something which has happened very recently.
0:23:02 > 0:23:04So that's not an old cut.
0:23:04 > 0:23:06Hmmm. It's not looking good for Xand.
0:23:09 > 0:23:12Yellowing tells us from all the studies that have been done
0:23:12 > 0:23:14that it's around about 18 to 24 hours
0:23:14 > 0:23:17when we see the yellow bruising start to come in.
0:23:17 > 0:23:18It doesn't come in before then.
0:23:18 > 0:23:23Dr Xand said this bruise was sustained as the burglar pushed past
0:23:23 > 0:23:24- him.- That's impossible.
0:23:24 > 0:23:26So that's an old bruise.
0:23:26 > 0:23:28Hmmm. Xand, you're in trouble.
0:23:31 > 0:23:36There is a tuft of Mr Grumble's hair on one of the shards of glass.
0:23:36 > 0:23:38Although the colour is similar,
0:23:38 > 0:23:41we have got to take it to the lab and have it tested.
0:23:41 > 0:23:44So what's the verdict from our forensics expert?
0:23:44 > 0:23:46You certainly have circumstantial evidence.
0:23:46 > 0:23:50You can say that the bruise was not acquired in the way that he said
0:23:50 > 0:23:52and the cut also.
0:23:52 > 0:23:56There are two things on which his account is completely inaccurate.
0:23:56 > 0:23:59There is no hiding from the medical evidence.
0:23:59 > 0:24:02Forensics experts like Professor Peter use their knowledge
0:24:02 > 0:24:04of the human body to solve crimes.
0:24:04 > 0:24:07Time to confront the prime suspect.
0:24:07 > 0:24:09- Thank you for coming.- We live here.
0:24:09 > 0:24:11There was no burglar, Xand.
0:24:11 > 0:24:13There was only you.
0:24:13 > 0:24:16You smashed my Doctor of the Year award and this tuft of brown hair
0:24:16 > 0:24:19implicates Mr Grumbles as your accomplice.
0:24:20 > 0:24:21No, not Mr Grumbles.
0:24:21 > 0:24:23I can't let him take any of the blame.
0:24:23 > 0:24:25It was all my fault.
0:24:25 > 0:24:28I knew it, but why did you lie to me, Xand?
0:24:28 > 0:24:30Only because I knew you'd be angry.
0:24:30 > 0:24:31I didn't mean to break your award.
0:24:31 > 0:24:33It was an accident, I promise.
0:24:33 > 0:24:36While you were out, we were practising for our ballroom dancing
0:24:36 > 0:24:40competition. I swung Mr Grumbles around, but I lost control,
0:24:40 > 0:24:43and then...
0:24:43 > 0:24:45I thought you'd be angry, so I lied.
0:24:45 > 0:24:48You should have known better, Xand. Lies will always be found out.
0:24:48 > 0:24:51I'm sorry, Chris. I'll glue the award back together right away.
0:24:51 > 0:24:54There you go, Chris, good as new.
0:25:00 > 0:25:04I EAR there's another patient in the emergency department.
0:25:04 > 0:25:06Right, very interesting.
0:25:06 > 0:25:08I wonder which body part is affected?
0:25:10 > 0:25:14Five-year-old Ethan is in the emergency department with his mum.
0:25:14 > 0:25:15He looks OK to me.
0:25:15 > 0:25:16So what's up, Ethan?
0:25:16 > 0:25:19There's a rubber in my ear.
0:25:19 > 0:25:21A rubber in your ear?
0:25:21 > 0:25:23How did it happen?
0:25:23 > 0:25:25Ethan was at school in a writing class.
0:25:25 > 0:25:26Very good handwriting.
0:25:26 > 0:25:28Yes. He was learning about Australia.
0:25:28 > 0:25:32- Awesome.- Ethan loves the really cool buildings and the kangaroos.
0:25:32 > 0:25:35Who doesn't? Chris, I don't see what the problem is.
0:25:35 > 0:25:37This all sounds perfectly nice and normal to me.
0:25:37 > 0:25:38Well, it was,
0:25:38 > 0:25:42but as Ethan was busy working away, a classmate lent over
0:25:42 > 0:25:43and put a rubber in his ear.
0:25:43 > 0:25:46- BOTH:- Ouch!
0:25:46 > 0:25:47Uh-oh.
0:25:47 > 0:25:48Whee!
0:25:48 > 0:25:50- Never put anything in your ear... - Or someone else's ear.
0:25:50 > 0:25:52..that's smaller than your elbow.
0:25:52 > 0:25:55Dr Robert Eastman is on hand to help.
0:25:55 > 0:25:56Have you tried to get it out?
0:25:56 > 0:25:59I tried to get it out at school and didn't....
0:25:59 > 0:26:02Nothing else in your ears that you know of?
0:26:02 > 0:26:03I hope not!
0:26:03 > 0:26:05I don't know.
0:26:05 > 0:26:07There could be a whole pencil case down there.
0:26:07 > 0:26:10- Is it OK if I have a look in your ears?- You need a torch.
0:26:10 > 0:26:13I've got a torch here, look, here you go.
0:26:13 > 0:26:15Dr Robert uses an otoscope,
0:26:15 > 0:26:18it's a magnifying lens with a bright light so he can see right down into
0:26:18 > 0:26:20Ethan's ear canal.
0:26:20 > 0:26:23It is difficult to see what's actually in there because there's
0:26:23 > 0:26:27a bit of hardened wax so I just want to get a second opinion on that.
0:26:27 > 0:26:29Enter Dr Jane Dawson.
0:26:29 > 0:26:31She has seen many a waxy ear problem.
0:26:31 > 0:26:34We will lie Ethan down and I'll see if I can hook out that wax
0:26:34 > 0:26:37and see if there is anything behind that.
0:26:38 > 0:26:40Have you caught anything, Dr Jane?
0:26:40 > 0:26:42Here comes a Gross Alert.
0:26:45 > 0:26:47Whoa! It's a chunk of hard wax.
0:26:47 > 0:26:49Don't panic, Ethan.
0:26:49 > 0:26:53Ear wax or cerumen comes out of glands in the ear canal.
0:26:53 > 0:26:57All healthy ears need it because it moisturises your ear,
0:26:57 > 0:27:01it traps dust and dirt and it has chemicals to fight off infections.
0:27:01 > 0:27:05Normally wax works its way out and is wiped away when you wash,
0:27:05 > 0:27:08but sometimes you can have too much and you need to see a doctor,
0:27:08 > 0:27:10just like Ethan.
0:27:10 > 0:27:12But what about that pesky rubber?
0:27:12 > 0:27:14Once we got that big chunk of wax out,
0:27:14 > 0:27:17I've managed to see right the way down to his eardrum and there is no
0:27:17 > 0:27:21- rubber.- It was that lump of wax that made him feel it was still in there.
0:27:21 > 0:27:24Have the docs ERASED the problem, Ethan?
0:27:24 > 0:27:27Brilliant. I love the hat, Ethan.
0:27:27 > 0:27:28- BOTH:- So long, partner.
0:27:30 > 0:27:32Next time on Operation Ouch!
0:27:33 > 0:27:35We have lift off.
0:27:35 > 0:27:36And we are now at maximum altitude.
0:27:39 > 0:27:40We're taking the plunge.
0:27:40 > 0:27:42That's not good.
0:27:42 > 0:27:45And we get our teeth stuck into things.
0:27:45 > 0:27:46That's disgusting.
0:27:46 > 0:27:49So we will see you next time for more Operation Ouch!
0:27:50 > 0:27:52Chris, what about us?
0:27:55 > 0:27:57I've got a bit of hip action going on.
0:27:57 > 0:27:59It's just my way. It's how I like to do it.
0:27:59 > 0:28:01- On Operation Ouch...- Super Xand!
0:28:01 > 0:28:04Super Xand! Xaaaannnndd!
0:28:06 > 0:28:09Is he going to come and say nothing to me now?
0:28:09 > 0:28:10- Has he gone? Is that it? - LAUGHTER
