Mao~
Breakfast is ready.
Okay.
Now, let's eat.
- Itadakimasu. - Itadakimasu.
It'll be your birthday soon, Mao.
Another year older.
Tasty?
Want another one?
Ah, that's right.
I didn't do octopus shapes today.
Regarding Doctor Tachibana
You told me, didn't you?
Tachibana-sensei says she has a daughter.
The truth is, she died 2 years ago.
Mao
Tachibana Mao-san was killed.
Ah, good morning. How are you?
- Very well, thank you. - I'm glad.
- Good morning. - Morning.
Director Kitabatake.
Is something wrong?
I hear Nitta-sensei is staying in A&D.
Yes.
She's changed.
Since she met Tachibana-sensei.
In order to save the patient,
I'll do anything.
Being a doctor isn't only about surgery.
I know that now.
That's true.
We've gained another reliable doctor.
What kind of person is Tachibana-sensei?
Oh? Takasugi-sensei,
have you become her fan?
Well, you could say that.
I see.
She's an excellent doctor, after all.
Has she always been the same?
Yes, what you see is what you get.
Is that so?
Thank you very much.
Is it that delicious?
Not really.
Then why do you keep grinning?
Does there have to be a reason?
I'm just wondering.
What is it? Please tell us.
Before I came to A&D,
patients were always being brought in
so I could never relax and eat udon like this.
So that's it.
So you switched from being an emergency doctor
because you wanted to eat udon.
No no.
I was still able to eat udon on my days off.
Excuse me!
What's wrong?
There's an emergency patient.
The emergency room is full, so A&D are being asked to take him.
We'll take him. I'll deal with him.
Thank you.
- Tamaru-sensei, come with me! - Okay.
She didn't get to eat it.
Blood glucose level is 48.
Kanda-san~
Kanda-san, do you know where you are?
In hospital.
How do you feel?
I feel a bit dizzy.
You haven't eaten much, have you?
Probably not.
You have low blood sugar.
That's why you felt sleepy.
I see...
We'll put you on a glucose drip.
- Prepare glucose. - Okay.
You'll soon feel better with the drip.
Thank you.
- I'll leave things to you. - Okay.
It'll start soon.
I'm feeling much better.
Can I go home?
I'll ask the doctor.
Kanda-san? Kanda-san!
Saturation has dropped.
Sensei!
Level 100 convulsions.
Why?!
Get one cylinder of diazepam.
No sign of stopping.
We'll intubate.
10 mg midazolam by intravenous injection.
The patient is Kanda Kōichirō-san,
male, 37 years old.
He collapsed in town and was brought in by ambulance,
and admitted to A&D.
Blood pressure is 90/60,
pulse is 110,
saturation 96,
body temperature 35.1.
His blood sugar level was 48,
so I diagnosed hypoglycemia and put him on a drip,
But just before discharge he developed severe systemic seizures.
He's currently stable,
but we don't know what caused the convulsions.
Could it be a brain tumour?
There were no abnormalities in the head CT.
Brain tumour and vascular disorder can be ruled out.
His blood pressure is low.
Convulsions are usually caused by neurological disorders,
so blood pressure should increase.
Could it be caused by the heart?
His heart motion is normal.
I did an echocardiogram.
Low blood pressure could be caused by dehydration.
But his body temperature is low.
A dehydrated person can't sweat,
so body temperature should increase.
That's true.
Even with severe infections or drugs,
it's possible for blood pressure to drop.
We'll have the blood test results in about an hour.
Let's wait for those, then.
Satomi-sensei, as his attending doctor,
look after him while taking care to avoid further convulsions.
Okay.
Low blood pressure and convulsions.
Medical Team
Lady da Vinci's Diagnosis
Subtitles by Candylemon
- Sorry to intrude. - Sorry to intrude.
Kanda-san, how are you feeling?
Now four female doctors are here.
This department has one patient at a time,
so we diagnose as a team.
Did you say there were four doctors in here?
There are only two of us.
Yes, two of you.
I know.
Tachibana-sensei, don't nitpick.
It's not fair on Kanda-san.
I didn't mean it that way.
Kanda-san has only just been taken off a ventilator.
He's just a bit woozy from the sedative.
The sedative should have worn off.
Kanda-san,
could it be you can see ghosts?
Yes, could be.
Tachibana-sensei, don't be ridiculous.
You don't have to listen to her.
- I'm sorry. - It's fine.
This is your first major illness, isn't it?
Yes.
So you're not on any medication?
No.
Are you feeling alright now?
Yes.
Excuse me.
The results of Kanda-san's blood tests are here.
His blood sodium is 118.
The water content seems excessive
compared to the sodium level.
So his convulsions were caused by hyponatraemia.
There's an imbalance between water and sodium,
so convulsions occurred.
If you hadn't been so quick with the tracheal intubation,
he could've had permanent brain damage.
Let's limit water intake to 800 cc a day.
That should restore the balance.
Okay.
That's good about his convulsions.
What?
Are there some in this hospital?
Are there what?
Ghosts.
Ghosts of female doctors.
- Restless spirits... - What are you talking about?
Don't be silly.
If Kanda-san really did see two ghosts,
that would explain why he said he saw four doctors instead of two.
What's this about?
Will you do me a favour?
Eh?
I hate things like this.
Huh?
Tamaru-sensei!
Don't scare me like that.
I'm happy to see you so late at night.
This is fate, without a doubt.
It's just coincidence.
Are those heavy? Shall I carry them?
No, thank you.
Still, you're keen, studying at this time of night.
Tachibana-sensei made me do it.
What are you researching this time?
"Maybe there are ghosts in this hospital",
she said.
Tamaru-sensei, do you like ghosts?
When you're free, can we go to an amusement park together?
Alone with Miyabe-san.
What a scary thought.
Ghost~!!
This is a new business plan you've thought up?
Yes.
If the hospital has a day-care centre,
we won't have to lose female doctors and nurses when they give birth.
If we create a comfortable working environment,
we'll also attract excellent staff.
I see.
It needs an initial investment,
but I feel it would be a realistic business measure.
- What do you think? - An excellent idea.
I'll suggest it to the funding group immediately.
If you would.
Kanda-san, how are you feeling?
I'm fine, thank you.
We discovered you had hyponatraemia.
Hyponatraemia?
Yes, it's when the amount of sodium in the body stays the same,
but the amount of water increases excessively.
That's why you suddenly passed out,
and why you had convulsions.
So that's it.
It improves quickly with treatment,
so you can go home tomorrow.
That's great.
Have your family been contacted?
Can anyone come to collect you?
I live alone, so I don't see my family.
A friend, then?
I don't socialise much anymore.
I'll be fine leaving alone.
I see.
From now on, be sure to eat properly
and keep to a regular routine.
I get so busy with work...
Although I do exercise to build my stamina.
Are you something like an international financier?
How did you know?
Eh?! That's amazing!
You have an aura of professionalism.
I'm really nothing special.
That's not true.
You seem like you'd be popular,
so I'm sure you have a wonderful girlfriend.
Could it be, you're single?
Yes.
I keep looking,
but I don't seem to meet anyone.
- How long have you been listening? - Quite a while.
You should've said you were here.
I felt like I'd be intruding.
What do you mean by that?
Sorry about that, I talked for too long.
I had fun, chatting with you.
Does your head hurt?
Ah... To be honest, yes.
Where does it hurt?
At the back?
Yes.
Why does he suddenly have head pain
even though we're treating the hyponatraemia?
It could be encephalitis.
Complications of encephalitis
could have caused the hyponatraemia.
Encephalitis of the occipital lobe can cause vision impairment.
That would explain the ghosts.
I'll check his spinal fluid this afternoon.
Good thinking.
- By the way, Satomi-sensei. - Yes?
You're more enthusiastic than usual.
I just want the patient to get well soon.
Could it be you like Kanda-san?
Eh?! What are you saying?
Of course not!
- It's obvious. - What are you talking about?
She likes him?
Kanda-san!
Calm down, please!
That's dangerous! Stop it!
What's wrong?
Kanda-san suddenly turned violent!
Intravenous sedative!
Kanda-san.
Kanda-san, it's alright.
Kanda-san.
You'll be fine.
Confusion?
Sedation is only a temporary measure,
so he may have another attack.
Kanda-san complained the back of his head hurt.
Encephalitis could have caused the hyponatraemia.
It would also explain his fit of confusion.
Have you checked his cerebrospinal fluid?
I plan to do it after this.
We'll wait for the results of that.
Satomi-sensei, if you would.
Nitta-sensei and Murakami-sensei,
you deal with outpatients in her place.
- Okay. - Fine.
Uematsu-sensei, get ready now
so we can have the sample test results quickly.
- Tamaru-sensei... - Yes?
Were there ghosts here in the end?
I read through all the books,
but I don't have a clue if the hospital has ghosts.
What's all this about ghosts?
Are you up to no good again?
No, when Kanda-san saw Satomi-sensei and me,
he said there were four of us.
I'm wondering if he saw ghosts.
You really are silly.
There are no ghosts in this hospital.
Not one incident or accident has occurred
that killed a female doctor.
Really?
How long do you think I've worked here?
That's true.
You should've just asked Iwakura-sensei.
You can't get everything from books.
Go on, thank Iwakura-sensei.
Thank you very much.
Huh?
So that means he has visual impairment?
That would be explained by encephalitis.
We'll know from the spinal fluid.
You're right.
Please don't do anything unnecessary.
Alright?
Understood?
Yes.
I've done an anaesthetic,
but if the pain gets too much, tell me.
I'll be fine.
I trust you, Sensei.
You damaged a blood vessel and got blood in the spinal fluid?
I'm so sorry.
You were an emergency doctor...
This isn't like you.
What have you told Kanda-san?
I apologised and said
I made a mistake, but there won't be any lasting damage.
Did that satisfy him?
Yes.
It's a good thing no major damage was done.
I really am very sorry.
We won't be able to test again for several days.
If it's encephalitis,
by the time we identify it and start treatment,
it may be too late.
In the worst case, it could be fatal.
I won't let that happen!
We can't wait for a retest.
I'll start him on acyclovir immediately.
I'm sorry, did I wake you?
No.
I'm very sorry about the spinal fluid test.
It doesn't matter.
Everyone makes mistakes.
Why are you being so nice to me?
That's because...
...I like you.
It appears Satomi-sensei
harbours romantic feelings for Kanda-san.
That's a problem, isn't it?
If she continues treatment while mixing her work and private life
it's clear further trouble will occur.
We should change his attending physician.
I don't believe that's necessary.
- Why not? - Because...
Ah~ I get it.
The one who brought Satomi-sensei to A&D
was Director Kitabatake.
If Satomi-sensei makes a mistake,
you've realised Director Kitabatake
will be forced to take responsibility
In that case,
shall we leave things as they are?
Don't misunderstand.
Pardon?
I think it's fine for doctors to have romance.
Of course, that's no excuse for making mistakes.
It's because I believe Satomi-sensei isn't like that
that I said there was no need to change doctors.
I apologise.
I'm sorry.
Even without resorting to such means,
at the next board meeting
I will definitely take the director's chair.
- Yes. - Yes.
A rash?
It's a side effect of the acyclovir.
He has renal failure.
What shall we do?
Satomi-sensei?
I trust you, Sensei.
Increase the infusion to protect the kidneys.
1 litre of saline at full throttle.
Acyclovir was administered because we suspected encephalitis,
but strong side effects and renal failure occurred.
Restricting water intake made him dehydrated.
We couldn't stop the acyclovir so we increased the infusion,
but there's been no improvement.
Wait a minute.
His blood pressure has fallen even more.
Even though we increased the infusion to protect his kidneys,
his blood pressure keeps on falling.
Did the infusion cause cardiogenic shock?
Cardiogenic shock would have made his limbs cold.
But Kanda-san's limbs aren't.
The heart motion was fine on the echocardiogram.
The heart isn't the cause.
Then how about septic shock?
If it's bacterial meningoencephalitis,
the shock should make his limbs warm.
Kanda-san doesn't have a fever.
A severe case could cause hypothermia.
If so, we have limited time.
Uematsu-sensei, take a blood culture
to identify the causative bacteria.
In order to raise his blood pressure,
start 5 mcg/kg/min dopamine.
Tamaru-sensei, tell Satomi-sensei
to administer meropenem antibiotic.
That's all for now.
The rash is spreading.
Sensei...
My illness...
Will it get better?
Yes, of course.
I'll be here,
so you'll definitely get well.
Thank you...
When I'm discharged...
I'll have to make up for the time off work.
You'll have to take it easy for a while.
Really?
Please take things slowly.
In that case...
...please go on a date with me.
Yes.
His blood pressure has reacted badly.
If it keeps dropping, Kanda-san will...
Increase dopamine to 10 mcg/kg/min.
Increase noradrenalin, too.
- Begin 0.1 mcg/kg/min. - Okay.
Thinking again?
Mao.
What's up this time?
We suspected hyponatraemia and encephalitis,
but the treatment didn't go well.
We don't know the cause,
and the patient's condition keeps on getting worse.
I see.
Satomi-sensei is working hard treating him,
so I want to help her.
Is she in love with that patient?
She denies it though.
Well, for women
even if they like a man they'll say they hate him.
Hey, Mao, how would you have experience of that?
I don't.
You said it ages ago when you were drunk.
I did?
That certainly does happen though.
Women lie about hating men,
and men lie about liking women.
Now four female doctors are here.
There are only two of us.
Yes, two of you.
- Does your head hurt? - To be honest, yes.
Are you something like an international financier?
How did you know?
Could it be you can you see ghosts?
Yes, could be.
This is your first major illness, isn't it?
Yes. Yes.
I'm fine.
So that's it.
He was lying.
Mao.
What?
You always help me.
I love you.
You're not lying?
I'm not lying.
Kanda-san.
I've realised something.
You're actually a detective, aren't you?
How did you know?
I can tell.
Only a detective would wear running shoes with a suit.
You're very perceptive.
Thank you.
Rather than a financier,
you're a civil servant.
Yes.
Could it be, Detective,
you're investigating the accidental death
of a female doctor the other day as murder?
That's got to be it, right?
Please don't tell anyone.
It's a top-secret undercover investigation.
Of course.
That's why you haven't had visitors.
They'd make you more conspicuous.
That's right.
The killer is the patient in the next room, right?
Please don't tell anyone.
If I don't arrest him here,
he may escape overseas.
I understand.
It'll be just between the two...
...three of us.
Thank you for your cooperation.
I hope you solve the case quickly.
Thank you.
Kanda-san, I've solved the mystery of your illness.
Eh~ So Kanda-san's a detective.
An undercover investigation?
Incredible...
When did you realise, Tachibana-sensei?
But if the killer is in the next room,
the doctors will be in danger!
What are you talking about?
Iwakura-sensei told you.
No female doctors have died in this hospital.
What?
What's going on?
Is this...?
If Kanda-san were a police detective,
his insurance card would be issued by the Mutual Aid Association.
Right.
But he's working undercover.
So we wouldn't guess he was a detective,
he used a business union insurance card.
However secret the investigation,
would he have made himself ill?
There's no way.
I'm totally lost.
What's going on?
Please tell me the truth.
Listen.
Kanda-san doesn't tell the truth
in response to leading questions.
You're a detective, aren't you?
How did you know?
The killer is the patient in the next room, right?
Please don't tell anyone.
Thanks to that, his disease is clear.
That means...
Kanda-san needs an immediate thiamine injection.
Okay.
Vitamin B1 deficiency?
Yes.
His blood pressure has already normalised.
He's off the dopamine and noradrenalin.
The thiamine has improved things dramatically.
Thiamine = Vitamin B1
Kanda-san went running during his lunch break,
and collapsed shortly afterwards.
Running used a lot of vitamin B1
to help sugar metabolism and create energy.
That's why he had low blood sugar.
When he was put on a glucose drip,
the remaining vitamin B1
was consumed suddenly and caused convulsions.
In addition, drinking only water
caused hyponatraemia.
We only looked for the cause of the hyponatraemia,
so we missed the vitamin B1 deficiency.
It's my fault.
I triggered it with the glucose drip.
It's not a routine test,
so initial diagnosis can overlook vitamin B1 deficiency.
It's not anyone's fault.
Besides, there's another reason the discovery has been delayed.
Reason?
The patient is a liar.
Liar? What do you mean?
Vitamin B1 deficiency has caused Wernicke-Korsakoff syndrome.
It's a form of amnesia
where you feel unsure of the time and place.
Patients sometimes forget events even from a few minutes ago.
They have sudden fits of confusion
because Wernicke's encephalopathy stops them understanding their situation.
And because they can't access their memories,
the patient feels confused
and unconsciously creates a story to fill the gap.
In other words, they lie.
So a disease can make someone a liar.
Kanda-san had Korsakoff syndrome.
So when you asked leading questions
like "Does your head hurt?"
he spoke as if it did.
Does your head hurt?
Ah... To be honest, yes.
So when he saw the ghosts?
It wasn't visual impairment due to encephalitis?
That was divergence paralysis.
Seeing 2 separate images.
Rather than encephalitis,
it was a neurological symptom caused by vitamin B1 deficiency.
The low blood pressure, convulsions and confusion
were all symptoms of vitamin B1 deficiency.
That's...
That means...
You have low blood sugar.
That's why you felt sleepy.
10 mg midazolam by intravenous injection.
I'll start him on acyclovir immediately.
Could it be, you're single?
I keep looking,
but I don't seem to meet anyone.
It doesn't matter.
Everyone makes mistakes.
I had fun, chatting with you.
Please go on a date with me.
Kanda-san isn't like that!
Kanda-san is... Kanda-san is...
Why are you being so nice to me?
That's because...
...I like you.
- Kanda-san! - Sensei?
Sensei, thank you so much.
Excuse me, but who are you?
I'll introduce you.
This is my wife.
Wife?
He suddenly went missing from his company,
and I couldn't contact him so I was worried sick.
I was about to request a police search.
He's fine thanks to you.
I'm truly grateful.
Go on, you thank her too.
Thank you very much.
Sensei?
Is something wrong?
No, nothing at all.
Please take good care of him.
Satomi-sensei?
Satomi-sensei!
Don't worry, she's stronger than that.
Good work~
Satomi-sensei...
Ah, it's Kanda-san!
I'm sorry.
What do you want?
I didn't sleep last night, so leave me in peace.
He's a good man, isn't he?
You may have been closest,
but I think we all rather liked him.
Doctors are human, too.
I think it's fine to fall for a patient.
I got heartbroken on my own,
and hurt on my own.
It's all meaningless.
I'm not so sure.
You were honest with your feelings, weren't you?
It was adorable seeing you do your best.
I haven't had anything to eat.
Hey, how about we all eat together?
I'll treat everyone.
Yes.
You're not lying, are you?
I really will.
Then...I'll have seasoned udon.
I'll take the orders.
I'll have katsudon.
- I'll have unadon. - You haven't looked at the menu.
It's the usual place.
I'll have duck nanban soba.
Okay.
I'll have a large helping of tonkatsu rāmen!
Hey, I want a large helping, too.
- You can't eat that much. - I can.
Ah, I want gyōza, too.
- Gyōza? - You can't have gyōza.
Good idea, let's have that.
Would you like to have lunch with us?
I'm buying.
In that case, I'll have Chinese noodles, thank you.
Chinese noodles for Murakami-sensei.
Okay.
Iwakura-sensei...
May I have tempura soba?
Of course.
A large serving of tempura soba.
Wait, regular-sized is fine.
- Excuse me! - What's wrong?
The ambulance corps want us to accept a young male patient.
Let me do it!
I'll deal with him.
Please.
Iwakura-sensei.
What was that for?!
Don't startle me.
I need the lift, too.
A day-care centre in the hospital?
That's a wonderful idea!
I think so.
So you've thought this far
about improving the working environment here.
Let's do it.
What?
Let's make this idea a reality.
Don't be irresponsible.
Where would we find the funds?
I'll implement it myself.
You should forget about it.
No no, don't worry about the money.
We'll be getting a subsidy from the Ministry of Health.
I was wondering what to spend it on.
This hospital day-care centre
will soon be a reality with that subsidy.
Thank you very much.
Well then.
Aren't you getting in?
- Please go on ahead. - No no, get in.
- Go ahead! - No no, get in.
I'm glad Satomi-sensei recovered quickly.
I didn't know what would happen if she stayed depressed,
but she's surprisingly romantic.
By loving someone,
people can recover from anything.
Tachibana-sensei.
What's wrong?
Tachibana-sensei...
Haven't you been lying, too?
The other day, I went to a grave.
You've been hallucinating, haven't you?
My right arm...
- Flesh-eating bacteria. - Flesh-eating bacteria?
There's a time limit of 24 hours from onset to save him.
Tachibana-sensei's on holiday...
Said she was going to the countryside.
The area affected is expanding.
It's hopeless.
6 hours left.
There must be something.
If Tachibana-sensei was here...
We have to keep hoping until the very last moment.
And the story
approaches the final chapter...
I have to save her.
For Mao's sake, too.
We'll always be together, forever.
