"Let me just say that it is the most critical step. It's because the most common thing is to die in the light. Of course, this refers to online chat. If you can still make an appointment with your appearance, most of them will be successful."

"..." Zheng Ren really wanted to die like this guy.

"Don't be nervous when meeting, just chat and say something to make her happy." Su Yun continued: "Then it is the most critical step - a second invitation. If you can make an appointment for the second time, it proves that there is no problem. As long as you don't commit suicide, it should be done."

"Uh..." Zhou Litao looked at the records on the a4 paper, and his head-up pattern was all twisted with bitter melon face.

"It's basically it, understand the spirit and study hard."

"Brother Yun, what..."

"Mr. Zhou, the patient has something to do!" A nurse knocked on the door.

"Okay, go now." Zhou Litao's face was entangled, and his distressed expression immediately disappeared. He changed into a very focused and serious expression, folded the piece of paper that recorded Su Yun's words and put it up.

"Brother Yun, Boss Zheng, you two wait for me."

"What patient?" Zheng Ren asked.

"A patient who suddenly lost his sense of smell." Zhou Litao said: "I asked him to do a head ct."

"Oh, go." Zheng Ren knew that this medical history was probably nothing, and he was too lazy to go and see it.

Olfactory is the characteristic of olfactory cells in the nasal mucosa. Injuries of the nasal mucosa, olfactory bulb, olfactory filaments or central nervous system junctions may affect the sense of smell.

Clinical manifestations include decreased smell, loss of smell, loss of smell, perverted smell, increased sensitivity to phantom olfactory and olfactory stimulation.

There are many most common causes of olfactory loss.

Including allergic sinusitis, nasal polyps, cold virus infection, rhinitis virus infection, head trauma, sulfur dioxide, nitride, and residual formaldehyde in the room after decorating the house.

In addition, long-term perfume spraying can also lead to olfactory failure.

Zheng Ren was thinking about what caused the patient. It might be the formaldehyde factor, because it is too common for the formaldehyde to exceed the standard when decorating your home.

Zhou Litao ran out immediately.

"Boss, be professional." Su Yun said with a smile.

"I think Zhou Litao can believe this." Zheng Ren said: "You don't even have a girlfriend, so you have the attitude to say this?"

"Tsk!" Su Yun said: "I don't want to find it, right? What girls don't have is. Girlfriend, just look for it on the street!"

Zheng Ren was too lazy to pay attention to him. It was so boring when Zhou Litao came back. The time was not long. There was a chatterbox sitting next to him, saying a few words from time to time. He couldn't even go to the system library to read books.

After waiting for a long time, Zhou Litao did not come back, and Zheng Ren felt strange.

He was really bored and stood up and pushed the door open.

Seeing a nurse busy in the corridor, Zheng Ren asked, "Please ask, where has Mr. Zhou been?"

"Teacher, I just came here. I don't know who Zhou is, I'm sorry." The nurse replied immediately.

Oh, the nurse who just came to 912 to study, Zheng Ren smiled.

When Su Yun saw the nurse entering the treatment room, he probably went to change the dressings, he smiled and said, "I'll ask."

Zheng Ren glanced at him and saw this guy turn around and go to the treatment room. He leaned against the door frame as if he had no bones. He started to talk and laugh.

It's really familiar, Zheng Ren thought to himself.

However, it was quite troublesome to ask him to ask something. After waiting for a few minutes, Su Yun came back with a look of pride.

“Where?”

"I said that the patient with smell problems just now went to the CT room and took a shower." Su Yun said.

"Is it a suck?" Zheng Ren wondered, "Is it epilepsy or spasm?"

"No one saw it, why do you ask so much?" Su Yun said: "I'll know when Mr. Zhou comes back."

"Where is Zhou Litao?" Zheng Ren was puzzled.

"It's said it was emergency rescue, and the draw was very good, and there was no way to do ct."

When I get restless, the ct image is full of artifacts, and it is the same as if I didn't.

This patient is probably sent to the neurology department, so that he can save the CT room from having nothing to do. If a sudden respiratory cycle stops, he will have to leave it.

But the patient with smell problems suddenly got a shot...

Something wrong with this medical history.

Zheng Ren began to think.

"Boss, if you can make a diagnosis now, I will be convinced." Su Yun said with a smile.

Zheng Ren also knew what he meant, and knew that a person had a sense of smell failure and then went to the CT room to twitch. If he had to make inferences based on these two points, he would not be able to do it at all.

But he was idle, so Zheng Ren went back to the house to sit down and began to count with his fingers.

"First, when a patient has a trauma in his or her olfactory nerve olfactory wires through the screen plate may be torn, or the olfactory bulb may be torn apart due to contusion."

Su Yun looked at his serious appearance and found it interesting. She sat opposite him and said, "Realistically speaking, the patient is not a trauma, otherwise, with Zhou Litao's personality, he would definitely say that the sense of smell failed after the trauma."

Zheng Ren nodded, Su Yun's judgment was correct.

"The second point is meningioma, metastatic tumor or invasive tumor of the anterior cranial foveal artery or frontal lobe, which can compress the olfactory bulb and olfactory bundle, resulting in olfactory damage."

"This is not reliable at all. If there is a meningioma, olfactory failure will not be a main complaint. And if the patient does not know it, it will generally not be accompanied by sudden convulsions." Su Yun said.

"I can't say that, it's just a high probability, this is doubtful." Zheng Ren said: "The possibility is about 5%.

"It's almost the same, I think it's a little less, you can continue." Su Yun was very interested in this air-oriented case discussion.

"Third, the olfactory damage caused by influenza is temporary and there is basically no convulsions, which is also ruled out."

"Fourth, occasional temporal lobe lesions are accompanied by temporary or paroxysmal olfactory. Loss of olfactory sense of odor combined with leucorrhea damage, which depends on volatile substances in food and beverages."

"Are the temporal lobe symptoms group?" Su Yun asked.

"Just saying this is not the symptom of the temporal lobe symptoms group." Zheng Ren said: "Volatile substances can cause olfactory failure, but convulsions and need rescue, which is too outrageous and will not be considered for the time being."

Su Yun increasingly felt that it was still very interesting to do this diagnosis and differential diagnosis, just like playing an intellectual game.

"Fifth, congenital factors are not considered, and the nasal mucosa, olfactory bulb, and olfactory neuropathy causes a decrease or loss of olfactory function; while damage to the junction of the central nervous system is usually not accompanied by any detectable loss of olfactory."

“Is the fifth point likely?”

"It's hard to say, it's probably not big, it's because it can't be accompanied by convulsions."

"After talking for a long time, did you have a diagnosis? The biggest possibility is an intracranial tumor, which is less than 5% of the probability." Su Yun said.
