Chapter 695: Baidu-ing a Diagnosis (Part 2)

Ji Xiang roared as if he had discovered a treasure.

Meng Qingfei ran back quickly, saying as he ran, "Wait for me a moment!"

These words were spoken to the Patient; thinking it probably wasn't a very serious case, Meng Qingfei wanted to check the urine discoloration immediately.

Arriving at the Duty Room, Meng Qingfei saw at a glance that the urine cup on the table was slowly changing color.

Just as the urine of a Porphyria patient would turn red, the urine of the Patient before them was gradually changing from the color of apple juice coming out of a juicer.

It was as if a drop of black ink had been dripped into the urine; the black mass swirled and diffused, gradually dissolving, and before their eyes, the entire cup of urine turned black.

Meng Qingfei glanced at it and immediately took out his phone.

Ji Xiang was speechless at this.

"Baidu-ing a diagnosis" was originally a mockery, but he hadn't expected Meng Laoshi, Meng Qingfei, to be so tireless in doing it.

Shouldn't one just state the Patient's problem directly at a time like this to show off one's status?

"Meng Laoshi..." Ji Xiang said softly.

"Wait a moment, let me check! The urine color is black; what kind of disease could it be?" Meng Qingfei said.

"Urological Tumor, that shouldn't be it, but it still needs to be checked carefully. This is damn unreliable. Xiao Ji, you did your first Standardized Residency Training in the Urology Department and are now performing Renal Cancer surgeries; have you ever seen black urine?" Meng Qingfei began to perform a Differential Diagnosis while holding his phone.

Ji Xiang didn't know whether to laugh or cry; if he didn't know Meng Laoshi, Meng Qingfei, he would definitely think he was here to be funny.

"No, I estimate it's dark red hematuria being described as black," Ji Xiang said helplessly.

"That's right, so this one is ruled out," Meng Qingfei muttered to himself.

"Eating red dragon fruit, foods containing anthocyanin components—if eaten in excess, urine can turn red or black, causing changes in the color components of the urine; generally, it can be relieved by reducing the intake," Meng Qingfei continued to perform the Differential Diagnosis with his phone.

"That doesn't seem to be it either. The Patient has been eating dragon fruit for 3 years? That would take a lot of love. Besides, stool is red when eating dragon fruit; it's very rare to see black urine. This point is questionable."

Ji Xiang watched Meng Qingfei performing the Differential Diagnosis with his phone and found it very interesting.

"Oral administration of buckthorn bark, senna leaves, artificial bezoar, Metronidazole, sorbitol, methylene blue, and other drugs; these drugs contain specific substances that react with tissues and organs in the human body, causing the urine to appear black."

"That's not right. Xiao Ji, have you ever heard of a case where eating senna leaves caused urine to turn black?" Meng Qingfei pondered with his chin in his hand.

"No," Ji Xiang reminded him, "Meng Laoshi, there are still patients outside."

Meng Qingfei slapped his thigh, reluctantly put his phone into his White Uniform pocket, wiped his hands on the back of his pants, and turned to go see the Patient.

Ji Xiang recalled Meng Laoshi's Baidu Differential Diagnosis, his mood inexplicably complex.

But it seemed Meng Laoshi had already found a breakthrough. Ji Xiang recalled it once and discovered that the key to the problem wasn't going online to do a Differential Diagnosis, but rather that Meng Qingfei had discovered the problem from the Patient's black underwear and subsequently observed the urine turning black.

Usually, it would be flushed away after urination; no one would be able to see that there was a problem with the urine. If it weren't for hospitalization, an indwelling catheter, and the urine remaining in the urine bag for several hours, it would be impossible to discover.

It looked like the whole process wasn't difficult, but Ji Xiang knew there was a chasm here, and Meng Qingfei had jumped straight over it.

If there hadn't been the preceding steps, even if one tore apart the online library, they might not have found the answer.

Ji Xiang quietly thought about Meng Qingfei's diagnostic process. Compared to the System NPC's performance of being "wise to the point of being a demon," Meng Qingfei was more like a living, breathing person, a living, breathing Doctor.

After more than ten minutes, Meng Qingfei walked in, beaming with joy.

"Xiao Ji! This is the first time I've known that buckthorn bark is actually a weight-loss product!"

"Uh..."

Ji Xiang saw Meng Qingfei flipping through his phone, searching for information related to buckthorn bark.

"Buckthorn bark and senna leaves are both drugs that cause diarrhea, and both can potentially cause urine to turn black. I haven't heard of it, but in the future, if I encounter a young woman with similar problems, I'll have to think of buckthorn bark."

Regarding Meng Qingfei's wild and imaginative thinking, Ji Xiang didn't know how to evaluate it.

"Furthermore, Metronidazole. I just asked; the Patient has no history of oral Metronidazole."

"Meng Laoshi, I've never heard of Metronidazole causing urine discoloration."

"I didn't find it either. Information on the internet is always a mix of truth and falsehood; if I can't find it, I'll just put it aside for now. Generally speaking, taking Metronidazole will cause the urine color to deepen, but turning black is a bit excessive," Meng Qingfei said.

"There is one more point—rare diseases like hereditary methemoglobinemia; usually, the Patient's urine turns black due to methemoglobinuria."

Meng Qingfei said a very tongue-twisting sentence, then began to recite it.

Ji Xiang awkwardly wanted to cover his face.

But Meng Qingfei didn't feel there was anything wrong with it. After reciting a long paragraph of medically related topics, he began to log into various professional websites to look for relevant information.

Finally, he looks like a professional Doctor, Ji Xiang thought to himself.

Because he was constantly interrupted by patients, it took Meng Qingfei nearly an hour to filter out two Gegan baodao.

Alkaptonuria!

A tongue-twisting and rare diagnosis surfaced.

Meng Qingfei excitedly slapped his phone in front of Ji Xiang, "Xiao Ji, look!"

His finger pointed at a paragraph, and Ji Xiang looked closely.

【In the middle and late stages, a large amount of homogentisic acid is deposited in the tissues. Extensive skin pigmentation can be seen, especially in the auricle, sclera, nose, cheeks, etc., which will appear brown or blue-black due to pigmentation. In the terminal stage, osteoarthritis can occur.】

From seeing the Patient's confusion to finding the basis, it took a full five hours.

In the dead of night, the logical closed loop was finally completed.

Although Meng Qingfei used the internet extensively for his search, Ji Xiang had a different perception of his behavior.

"Meng Laoshi, it really seems to be Alkaptonuria; it's exactly the same as what we saw."

"The Patient needs a Joint replacement; there are precedents. Are you currently following Deng Chaohong in the Orthopedics Department?"

"Yes."

"Then I'll talk to the Family Member tonight. If they agree to the surgery, I'll have the Patient go find you tomorrow, and you take them to let Deng Chaohong take a look."

"Okay." Ji Xiang simply replied to Meng Qingfei's words; Meng Qingfei's dirty White Uniform seemed to be radiating light.

Meng Qingfei seemed very happy; he reached into Ji Xiang's pocket, took out a cigarette, and lit it with satisfaction.

"Xiao Ji, I've discovered that your habit of carrying cigarettes is really good. I don't want to smoke too much, so I don't carry them myself. Taking cigarettes from your pocket is simple and worry-free, and I'm a little embarrassed, so I end up smoking less."

Ji Xiang looked at Meng Qingfei. He was full of joy; in any case, Ji Xiang couldn't see where he was embarrassed at all.

"Meng Laoshi, do you often see patients like this?"

Meng Qingfei looked up at Ji Xiang and smiled slightly, "When experts cross swords, they can pluck a flower to injure someone. Don't be constrained by a single move or style; as long as you can cure the patient, that's all that matters."
