Doctor: It's reasonable to perform surgery on yourself.

On the screen was a little girl with skin so tender that you could pinch water out of it.

The child stared with big watery eyes, with a look of grievance and innocence. There was nothing wrong with her face, but her purple lips instantly caught Xu Qiu's attention.

A closer look revealed that the purple lips were actually round rashes one after another, with a purplish color and clear edges, spreading to the middle and the surroundings, and finally forming a series of hollow ring-shaped rashes, densely packed, even overlapping each other, which looked quite creepy.

This...

Xu Qiu's brain was working fast, and he ruled out hypoxia first.

Generally speaking, cyanosis of the nail bed and lips is the most representative symptom of hypoxia, but the child in the picture is obviously not one of them.

Cold sores?

The characteristics are not quite the same. Cold sores are also called fever herpes. Its characteristics are that there are tiny blisters filled with fluid on and around the lips, which appear in patches or pieces, and the blisters will burst.

Or is it cheilitis?

Acute cheilitis is mainly manifested by redness and erosion of the lips; while chronic cheilitis is mainly characterized by dryness, cracking and peeling. In any case, it does not match the rash of the little girl.

Thinking of this, the more reasonable one is perioral purpura.

The only things that can cause purpura are allergies and ruptured small blood vessels.

Thinking of this, Xu Qiu looked at Bai Xi and asked, "What medicine have you taken recently?"

"Ah, you are worthy of being my brother. The doctor of Jiade Medical also guessed so!" Bai Xi's eyes lit up.

The child was found to have a problem after school today, and was sent to Tu Yanyan at that time.

A doctor from Jiade Medical came out specially, took a closer look, asked about the medical history, and found that the little girl had been suffering from oral ulcers for some time, so she had been using watermelon frost externally these days.

Therefore, the private doctor guessed that the child was most likely allergic to watermelon frost.

And judging from the child's performance, the allergy is quite serious, which may endanger the respiratory system. If there is laryngeal edema or something, his life will be gone.

After Bai Xi finished describing the situation, he added: "So now the child is staying in Jiade Medical. He should be taking anti-allergic drugs, and there is a ventilator waiting next to him."

What a luxury... Xu Qiu couldn't help but sigh.

Let alone clinical medicine, even in Baiyun Provincial Hospital, I'm afraid no ward can always have a ventilator. Only high-end private medical institutions like Jiade Medical can be so generous.

However, Jiade itself follows the American way of "as long as you have money, the dean can be called to carry shoes", which is completely different from Daxia Hospital's comprehensive coverage regardless of class.

"Watermelon frost allergy?" Xu Qiu was silent for a while.

In theory, allergic patients may indeed cause rashes, but he always felt that the patient's symptoms were familiar.

If it is an allergy, it is generally not limited to the lips and mouth, and at least it will spread to the face.

So is it a ruptured small blood vessel?

To be more precise, this type of purpura should be called purpura caused by increased intravascular pressure. The cause is violent, sudden and persistent muscle contraction and local negative pressure, which leads to a sudden increase in pressure in small blood vessels, causing small blood vessels to rupture and bleed.

The external manifestation is purpura.

However, how can a child have a sudden increase in intravascular pressure?

Xu Qiu narrowed his eyes and thought again... The main causes of purpura are allergies and vascular damage. In the final analysis, there are actually three essences: abnormal vascular wall function, abnormal platelets, and coagulation dysfunction.

However, since the doctor at Jiade Medical gave a diagnosis of "allergy", they must have checked these three items.

So the child does not have vascular disease?

This is also in line with Xu Qiu's intuition... At least from the photo, the girl looks better than Bai Xi, who played games all day, and her skin is translucent, which is not a state that patients can have.

Moreover, it is still the old problem. Just a photo can provide too little information.

Xu Qiu was about to shake his head and look away when he suddenly thought of something and his pupils shrank.

Wait!

A surge in intravascular pressure?

Generally speaking, ordinary people rarely experience a sudden increase in vascular pressure, but children are creatures that cannot be guessed by common sense.

No one knows what kind of brain circuits are in their little heads.

For example, thinking that you are a mushroom is a mental illness for Hu Jingying.

But if it happens to a child, I am afraid that not many people will think it is wrong - because children themselves are full of too many incomprehensible ideas.

"Let me see it again." Xu Qiu said.

Bai Xi was about to turn off the screen. When he heard this, a glimmer of hope emerged in his eyes, and he quickly handed the phone over again.

Xu Qiu looked at the photo in his hand, enlarged and moved it, and carefully distinguished the distribution of hollow annular purpura.

After more than ten seconds, his eyes lit up, and he finally discovered the internal rules hidden in this seemingly messy rash.

There are dozens of densely packed rashes, and their sizes and shapes look completely different, but this is the result of the purpura spreading and fading in the subsiding period.

In fact, if you shrink each ring-shaped rash inward and return to its original form, you will find that each ring is surprisingly similar... or simply the same!

Thinking of this, Xu Qiu's frown suddenly relaxed.

If this is the case, then basically all kinds of diseases can be ruled out.

No disease can reproduce almost completely identical symptoms. Even skin diseases such as urticaria have different sizes, shapes and unevenness of rashes.

There are only other reasons for this.

At least there is good news. The little girl is not suffering from an incurable disease.

As for the diagnosis made by Jiade Medical, it is enough to just listen to it. It is not very meaningful for reference.

"Can we play a video?" Xu Qiu asked.

In the final analysis, we still have to see it with our own eyes.

Bai Xi's mood immediately jumped up, and he hurriedly said: "Is it enough to play a video? Jiade is not very far from here. I will ask them to come over?"

If nothing unexpected happens, Tu Yanyan should be there, so it is just right to deal with this matter.

Xu Qiu also thought of this layer. It is a matter, so it is better to deal with it together, so as not to delay more of his time.

So he agreed and said, "It doesn't match the symptoms of allergies, so there should be no danger to his life... Of course, he still needs to be sent by ambulance, just in case."

"Leave it to me!"

Bai Xi agreed immediately and called excitedly.

The other end of the phone was obviously quite surprised to hear Bai Xi's words, mostly joy and shock.

Bai Xi's best friend thought that this guy was talking nonsense, but he actually got an appointment with Dr. Xu...

And it was a private consultation!

If this is put outside, it is more or less considered as practicing medicine outside the place of practice. I guess only a big shot like Xu Qiu has the courage to do this.

"The door is not closed, bring them in when they come." Xu Qiu didn't delay much and went in with the door open.

Then he called Shi Lian.

Tomorrow is the last game of the famous sword competition. As a teacher, he must encourage these young doctors in his own hospital.
