idk, I'm gonna put this one on the family. They didn't think it was important to mention this guy swam through a large river and then hiked his way through the entire southern US before suddenly falling ill shortly afterwards?
I would guess it's because doxycycline is bacteriostatic (doesn't kill bacteria, just stops them from reproducing) so it it will take a bit more time for the disease to start getting better and the damage and the disease can still progress while the bactrial load doesn't go up.
Disagree. Clinical history was never important in this case. You must consider leptospirosis/HPS in the situations like this (acute onset, rapid progression, fever + ARDS/DAD + liver failure + renal failure), even if you don't have enough information about the patient's personal life. And I believe that is the primary reason why they started doxy. Lab confirmation always takes some time. That dramatic clinically history probably was just a coincidence. Although clinical history does matter in many cases, its importance is too much exaggerated in this video.
@@SireCs133 You have to consider how antibiotics work. Many antibiotics work by blocking replication of bacteria. Antibiotics don't 'kill' bacteria themselves. They just block replication, and immune cells kill bacteria and clean up bacterial proteins. On the other hand, symptoms of bacterial infection are mostly due to inflammatory processes. It takes time to see clinical improvement after initiating antibiotics, even the appropriate ones.
Med student here Question If I have multiple micros that can cause similar symptoms, how does one differentiate between them especially when the patient's health is deteriorating rapidly?
@@faresasfary Consultant pathologist here. To identify pathogens, you can try microbiological (bacterial culture or MALDI-TOF), serological (antigen/antibody), or molecular (PCR) detection methods. Whether to perform them all together or stage by stage depends on how severe and urgent the patient's condition is.
@@faresasfary Good question. The thing is, you don't really have to know what pathogen is causing the illness at that situation. What you have to know is the probabilities of possible pathogens in specific situations. All you have to do is to select the appropriate broad spectrum antibiotics that covers the most of the frequent pathogens. It's all because microbial confirmation takes time. After you identify the specific pathogen and its antibiotic susceptibility, then you decide to switch the antibiotics accordingly. That's the basic concept of empiric antimicrobial treatment.
Love this kind of videos..
Does anyone any channel provide this kind of videos?
This is amazing
amazing.

Thank you. +103 Sasha
Why did he continue to deteriorate even after doxy administration?
