Chapter 1845 Intellectual "Game" (Monthly Ticket 33000 Plus More × 66)

"You can't say that, we have at least ruled out a few possibilities." Zheng Ren's expression was as serious as when Su Yun and Zhou Litao were explaining their problems just now.

"What are you thinking about now?"

"The most common thing that can be posted is formaldehyde poisoning." Zheng Ren said: "Minor poisoning can cause blurred vision, dizziness, headache, fatigue and other systemic symptoms. Severe poisoning can cause pulmonary edema in patients, hypoxia and Symptoms such as convulsions can occur."

"It's not like." Su Yun shook his fingers, "First of all, after formaldehyde poisoning leaves the toxic environment, it is difficult for the disease to continue to progress. Let's not say that it is directly relieved, and it becomes like a normal person, but it will evolve from a loss of smell to convulsions and convulsions. , is unlikely."

Zheng Ren also felt that this diagnosis was a bit forced, but Su Yun's judgment was correct.

He continued to meditate, tapping his fingers lightly on the table. Su Yun felt that if this guy was old, he would be like Old Director Pan.

Or maybe he imitated Director Pan intentionally or unintentionally.

"Not formaldehyde poisoning, nor sulfur dioxide poisoning, intracranial tumor? This possibility..." Zheng Ren said softly while thinking.

"You also recite it during the exam? Is it annoying?" Su Yun said contemptuously, "Would you like to take your fifth edition of Surgery to recite paragraph by paragraph when the whole hospital consults in the future?"

"Hmm..." Zheng Ren continued to ponder as if he didn't hear Su Yun's taunt, "Anything else, it's a hallucination. I felt like I couldn't smell, and then I had a seizure."

"You can write fantasy novels. If this happens, it won't show up sooner or later, but it will show up in the CT room. Isn't that nonsense?" Su Yun said.

"If it's a seizure, wouldn't it be better for us to understand this word as epilepsy? For example, reflex epilepsy syndrome.

Almost all seizures are epilepsy induced by specific sensory or complex cognitive activities, such as reading epilepsy, startle epilepsy, visual reflex epilepsy, thermal bath epilepsy, card epilepsy, etc. Removal of triggering factors, seizures also disappeared. "

"You mean..." Su Yun was also puzzled.

"Claustrophobia is usually more obvious when doing MRI. But there are also patients who get sick when doing CT, and in SCI..."

"Don't show off your data, epilepsy is possible, but can it explain the loss of the sense of smell?" Su Yun continued to find fault.

Indeed, Su Yun was right.

This belongs to pressing the gourd to float the scoop, and the sense of smell and epilepsy cannot be put together.

Besides, things like claustrophobia are rare.

Zheng Ren let out a long breath and continued to think.

"Hey, do you want me to ask about other medical history?" Su Yun said with a smile.

"Are you looking for Zhou Litao?"

"Who knows, first ask the little nurses, in case they can provide useful information."

"If you want to have fun, just go, don't ask about the medical history." Zheng Ren said: "In fact, epilepsy and smell loss can also go together."

"For example?"

"Antihypertensive drugs, which can improve heart function, can also occasionally damage the olfactory nerve."

"It's too far-fetched."

"Abnormal discharge of brain cells and neurons... nerve damage..." Zheng Ren began to mutter again.

"Don't think that you can look more professional if you tell epilepsy about abnormal discharge of brain cells and neurons." Su Yun said.

"That's not the case..." Zheng Ren raised his hand and said, "Nerve damage doesn't necessarily have to be caused by trauma. Other factors may also cause nerve damage."

"Tumor invasion, chemical elements in the air, what else do you want to say? These have just been diagnosed."

"Parasites, such as amoebas, first enter the human nasal cavity, are ingested by phagocytosis through the supporting cells of the olfactory neuroepithelium, and then pass through the cribriform plate along the axonal space of the unmyelinated olfactory nerve terminal filament After that, arrive at..."

As Zheng Ren spoke, he froze.

Su Yun also had some doubts in his eyes, and he looked at Zheng Ren in surprise.

Originally, he wanted to refute, but the disease of primary amebic meningoencephalitis does have anosmia and symptoms of epilepsy. When the words came to his lips, Su Yun swallowed them back.

Uh……

"It's primary amoeba meningoencephalitis!" Zheng Ren said, and then added: "This diagnosis is relatively reliable, with a probability of 80%!"

"Primary amebic meningoencephalitis? How did you get in?"

"Ask Mr. Zhou, is there any wound near the patient's nose? By the way, how old is the patient? It may be that the pimple has been squeezed and infected with amoeba."

The more Zheng Ren said, the more confident he became.

Because the previous diagnostic flaws are too obvious, as long as there is basic logic, they can be ruled out. They are one type of differential diagnosis, a sacrificial diagnosis for which reasons are found to be denied.

"At first there was an abnormal sense of smell, but then dizziness, headache, nausea, and jet-like vomiting followed by epilepsy." Su Yun frowned, and said a reason that he was not sure about.

"The location of the infection is different, and the progress of the disease may be staggered." Zheng Ren said: "The disease is very complicated, and the steps in the textbook are only one that will appear with a high probability."

Sure enough, Su Yun's words were immediately refuted by Zheng Ren.

Zheng Ren then picked up his phone and made a call.

But the phone rang at the door, and Zhou Litao pushed the door in with his phone.

"Boss Zheng, Brother Yun, I'm sorry, the patient had some unexpected problems and came back late." Zhou Litao said apologetically.

"Is the patient's mouth and nose triangle traumatized?" Zheng Ren asked directly.

"Uh...no." Zhou Litao said, "No trauma."

Zheng Ren was a little disappointed, but immediately asked, "How old is the patient?"

"An old man in his sixties." Zhou Litao replied subconsciously.

Is it wrong?

"Boss Zheng, what illness are you thinking about?" Zhou Litao asked cautiously seeing Zheng Ren's unkind expression.

"No trauma? What about rosacea?"

"Uh..." Zhou Litao was stunned for a moment, wondering what happened to Boss Zheng?

"There is rosacea, and the patient has been drinking a lot of alcohol all year round. For the time being, I think it is the convulsions caused by alcohol." Zhou Litao said more immediately, so as to save Boss Zheng from chasing his ass to ask.

"No! It's primary amoebic meningoencephalitis." Zheng Ren said, "Sedate the patient and hurry up for a CT scan. By the way, we need to do a cerebrospinal fluid test."

"..."

Zhou Litao was sweating all over just now, and when he came back, he was baffled by Zheng Ren's slap in the face. He was even more baffled than when Su Yun taught him the lesson.

"Rosacea, when exposed to raw water, there is a very small probability of amoeba infection. The incubation period is short, and the onset is sudden." Zheng Ren said with certainty: "Let the doctor in the inpatient department check the cerebrospinal fluid immediately, and then do a CT. .”
