Intensive Talk with Prof Falagas

Summary:
Bacteria develop multiple resistance to antibiotic
By:
1)producing B-lactamase
2)overexpression efflux pump to release extra antibiotic
3)antibiotic modify enzyme
4)ribosomal mutation
Thus appear all superbug such as ESBL, carbapenemase producing klebsiella etc
Pt infected with ESBL +ve had relative risk 1.85 of mortality compared to normal bugs
Treatment of commonest bugs in ICU –Acinetobacter spp.
Recommended to do C+S with MIC
Therapy promptly early
Start therapy right at beginning
Modification therapy as nessasary (de-escalation) early
Tigercycline- a new agt
It evades tetracycline efflux pump and ribosomal protective mechanism
Bacteriostatic
That is limitation no good blood level for therapeutic
Varied response to acinetobacter
Imipenem –launch with 4g/day
Recommend 2g/d as reduce seizure
Not enough as moderate susceptible organism need 1g qid .
Recommended for high MIC acinetobacter to give prolong infusion meropenem 1 g tds as long as 3 hr compared with 30min normally given.
Study proved similar dose with prolong infusion better outcome
Colistin monotherapy
Got 52% isolates for acinetobacter were polymycin only susceptible
The rest need colistin and one other antibiotic (rec add carbapenem)
As highest % of survival
Benault et al. showed Obesity highest rate septic shock
Partly related with leptin def
DM
FOsfamycin-good for Klebsiella spp and pseudomonas spp.
Another talk by gastro
If NDM1 may give fosfamycin + carbapenem.
UGIB
Commonest cause H. pylori followed by NSAID, Antiplatelet
Risk of UGIB-age, multiple co-morbidity and H/O peptic ulcer
If pt got cardiovascular problem, may restart antipltelet after 4-5 days of peptic ulcer

Neurology examination (basic fundamental)

Student, house officer, medical officer hates the most ! neurology system. Coz, no particular song lyrics to sing ! all other system got same chores to sing.-Inspection, palpation, percussion and auscultation.

To me, neurology famous song would be look and proceed + investigator.
The rule no 1- when ask to look at the face, please do look for upper and lower limb grossly also ! This is what i called LOOK thoroughtLY !

Rule no 2-Pretend yourself as a wireman,
rule of thumb - for neuro, first ,level of lesion-brain, cerebellum, brain stem, spinal cord, anterior horn , peripheral nerve or muscle.
After that second question- left or right brain or level of lesion
lAST-cause of the lesion
Then bingo- You are PASSED.

rule no 3- don't panic- apply for all

Rule no 4- common thing come first-apply for ALL physical examination.

Rule no 5- use your rule no2 rule then give the diagnosis with statement like this is a 40 year old (middle-aged) gentleman with left hemiparesis which is due to right cerebral infarct. etc..
Bingo, you are passed then just answer all the question.......to get better marks.


Good luck, the next will be cranial nerve. If you like the blog, pls do CLICK on google ads on top or side to show APPreciation! Your appreciation is my best inspiration!
