[lorena] sorry to interrupt guys, what is the topic you are discussing today?
[dua_frank] yeah take your time to enjoy the 99
[lanny] Mplug sd has hx of constipation
[dua_frank] pulmonology lorena
[lorena] thank you dua
[samantha] sanz one doubt
[dua_frank] you'll find the schedule listed in the chat forum for every day
[sanz] sure sam... ?
[dua_frank] welcome
[dua_frank] :)
[lorena] great, and now i know the time too. See you tomorrow .bye
[samantha] while doing UW did you find it difficult
[dua_frank] bye
lorena has left the chat.
[lanny] megs tell us the diff
[sanz] sam, yes i thought the UW qs are picky but they are there for a reason... just try to understand the concept rather than memorising
[samantha] it is silly but it seems like a mountain sometimes
[megs] lanny one has association with CF and other has just failure to pass meconeum
[dua_frank] so plug has no CF
[sanz] kap qbank qs are less picky... but i learnt less fr them even tho i got a higher overall score in kap qbank...
[dua_frank] but meconeum ilius always has CF association?
[samantha] it is better to time it and do or just understand it?
[megs] yes..dua
[dua_frank] thanks
[samantha] thanks sanz
[megs] but meconeum plug is not always associated WITH CF
[dua_frank] ok
[sanz] time it and do definitely, sam!!! Then go back and take yr time understanding it. I do a timed block of 46 qs, then spend 2-3 hrs understanding all the qs...
lanny has left the chat.
[megs] SANZ how many q u did daily??
[sanz] 3 blocks a day megs
[megs] u mean above 100 q daily sanz?
[sanz] i didnt have much time cuz i was aiming to finish everything in 3 months so that i can go on holidays...
[dua_frank] for two months?
[sanz] 46 q x 3 each day
[dua_frank] wow thats a lot, i'm doing like only one block per day right now
[megs] oh that was really
[megs] fast
[sanz] dua but i dont do anything else.. i dont listen to kap lectures or other lectures
[dua_frank] how many are you doing every day megs?
lanny has left the chat.
[megs] one block each day
[dua_frank] me too
[dua_frank] you did that for 3 months sanz?
[sanz] everyone has differnt ways of studying i guess...
[dua_frank] wb lanny
[sanz] i did UW for 25 days and kap q bank for 15 days
[lanny] im back
[dua_frank] ok
[megs] ok sanz
[dua_frank] lanny how many q blocks do you do in a day?
[samantha] thanx for sanz
[dua_frank] and sammy you
[dua_frank] ?
[lanny] dua mec ileus is assoc with CF
[lanny] M plug sd is not
[dua_frank] yes got that thanks
[samantha] doing UW wrong ans dua
[lanny] oh dua hard to tell you know i work part time so soetimes i do more other times less
[dua_frank] oh ok
[lanny] i took UW as a learning tool did q after reading second time
[dua_frank] ok
[sanz] everyone has differnt strategy of doing things i guess... as long as it works for you... one thing i find very beneficial is that after doing a block, straight away read up on the wrong qs and learn the comcept
[dua_frank] yes thats true
[lanny] i am taking kaplan now as a test and averaging 70
[dua_frank] nice 70 is really good, yuo're heading for a 99 too
[sanz] yes lanny :)
[lanny] yea right!!!!!
[lanny] kaplan q are not as easy as people think
[dua_frank] no really, ask sanz, she will tell you the same
[lanny] easier though than UW
[sanz] yeah... UW is better i think...
[lanny] so far i have spent nearly 5 mths on UW
[dua_frank] how was NBME sanz?
[dua_frank] 5 months :O
[dua_frank] how many times did you read the whole q bank lanny?
[sanz] NMBE is like UW... the real exams is as hard as NMBE... maybe even a little more mentally challenging
[lanny] i just finished the whole bank 2 wks ago
[sanz] but lanny works
[dua_frank] oh so its worth taking it then
[dua_frank] oh yes, i forgot about that
[dua_frank] lanny you sure work hard buddy
[lanny] but like i said i spent time reading the wrong and correct answers
[sanz] dua, it's worth taking it to see where you stand... but if not i have sent you the CD with the qs...
[dua_frank] when does FEV1/FVC ratio remain normal?
[samantha] yes 2nd time it makes more sense and can make notes
[dua_frank] yes thanks a lot for the cd sanz :) really appreciate it
[lanny] yes dua could have been faster if i didnt work
[lanny] but hey the pace was right for me had to pay more money t hough
[dua_frank] you're doing good lanny, don't worry about your exam, i'm sure you will do great and score a 99 too
[dua_frank] restrictive lund disease

[dua_frank] meaning restrictive yes sanz
[megs] in restrictive lung disese dua
[sanz] oh megs, you know you mentioned abt partogram when we were chatting gynae?

[dua_frank] my GOD!
[lanny] whats a partogram
[megs] thas nicw
[dua_frank] did they ask you to read it???
[samantha] yea what is it?
[sanz] they give curves and you gotta fingured out if it's latent or active phase arrest etc
[dua_frank] oh man
[lanny] oh ok
[dua_frank] i better read it up again
[sanz] not too diffiult cuz its just a curve
[sanz] but i think cuz megs had mentioned it before, the qs didnt come to me as a shock
[lanny] it has to be at least 4 cm for it to be active phase arrest
[megs] yes
[sanz] so megs, thnx! Things like this i learnt fr all of you :)
[samantha] sanz how mich did you get in step 1?

[dua_frank] will atelectasis be visible on cxr normally?
[dua_frank] no megs
[lanny] yes
[megs] no there is not
salsterzz has left the chat.
[dua_frank] yes
[lanny] atelectassis is visible dua
[dua_frank] is not usually lanny
[dua_frank] not on the lungs i mean
[dua_frank] you will not see lobular collapse
[dua_frank] like you see in collapsed lungs
[lanny] no the lung appears unaerated
[dua_frank] its the collapse of the terminal and small bronchioles and alveoli
[dua_frank] yes smaller in size
[lanny] yes dua i aagree
[lanny] like u said its not ususally seen
[dua_frank] what does it show on x ray of surrounding structures when its an upperlobe atelectasis?
[lanny] lower?? lobe
[dua_frank] tracheal pull to the same side
[dua_frank] how about lower lobe atelectasis?
[lanny] yes
[samantha] there will be collapse of the whole lobe
[megs] mediastinal shift
[lanny] to the same side
[dua_frank] no that is massive aletectasis megs
[samantha] seen on chest xray dua?
[dua_frank] in lower lobe there is elevation of the diaphragm on that area
[lanny] but it is still ateleciasis dua
[lanny] right dua
[megs] ohh got it dua
[megs] nice one
[dua_frank] no sammy, there will not be a collapsed lung on cxr in aletecsis
[lanny] thats why lower lobe os more visible
[dua_frank] don't confuse atelectasis with collapse of lung you might see in pleural effusion of pnemothorax
[samantha] ok dua
[dua_frank] rx?
[lanny] yes dua look for small airway involvement
[megs] bronchoscopy dua
[dua_frank] to remove plug yes
[dua_frank] but initially deep breathing and coughing up
[megs] and remove the offending factor
[dua_frank] and incentive spirometry
[samantha] atelectasis is just a small area rt?
[dua_frank] which is why you encourage patients to cough out the mucus post operatively
[dua_frank] to prevent atelectasis
[lanny] pulmonary to ilet
[samantha] and collapse is like an entire lobe
[dua_frank] sammy it can be huge too, its about the small bronchioles and alveoli collapsing rather than the whole lung
[dua_frank] its like collapsing within itself
[samantha] thanx dua
[dua_frank] welcome
[lanny] yes dua youre quite right good pt.
[dua_frank] how exactly is this pulmonary toilet given lanny/
[megs] pocorn calcification on x ray whats dx???

[megs] ohh got it
[dua_frank] whats the drug with seizures lanny?
[dua_frank] in UTI
[lanny] nicely put dua EVEN WITH MEDICATION B AGONIST ETC WATCH CLOSELY
[lanny] i have seen it in my practice
[dua_frank] i have seen it in me :) i'm an asthmatic but thankfully a loud one always :)
[lanny] have forgotten the q dua will have to scroll
[lanny] ok dua well youlle get all the q right in asthma
[dua_frank] lol not really, i don't even know which type i have yet
[dua_frank] it seems like i have a mixed picture
[lanny] i had a close friend who died od SLE after6 yrs of diag she was well until day she died of rrythmia i love SLE since then!!
[megs] he he i had extrenisc one
[megs] but now got relief lol
[lanny] good megs
[dua_frank] thats sad
[lanny] yea i used to tell her that shes ok cause she was really never ill
[lanny] she did ask me once about prognosis and rubins pathology said 5 yrs after diag i never told her that though
[lanny] but it came to pass
[dua_frank] :(
[megs] ohh
[lanny] i am inquisitively watching her son for heart sms!!
[megs] thats intelectuallization lanny
[lanny] you got it megs
[megs] yes
[lanny] i always ask the grand mother whern he goes to the doc did the doc listen to his heart??
[dua_frank] do you know why you can't give cromolyn in kids with acute attack?
[lanny] but of course dony want to alarm the family
[megs] its mast cell stabilizer..so wont work once attack sets in
[megs] just it can prvent histamine relesae
[dua_frank] no megs my book says it may increase the attack
[lanny] does not work in acute attacks
[dua_frank] i didn't understand how it can inc the attack, i know it can't help acute attacks though
[megs] i havnt come across that dua
[dua_frank] this is case of children not adults that too
[lanny] its not used for acute attacks not helpful
[lanny] even in adults
[dua_frank] does aminophylline work in acute attacks?
[megs] yes it does
[dua_frank] nope
[lanny] i have seen this in an adult med q they gave all signs of exercise ind asthma
[megs] :o
[dua_frank] it improves contractility but is a weak bronchodialator
[megs] why dua
[lanny] and ask for trt to stop it
[dua_frank] stop what lanny?
[lanny] inhaled b agonist and cromolyn is what you give
[dua_frank] improves diaphragmatic contractility that is
[dua_frank] yes exercise induced you can give those two lanny
[lanny] in acute attacks of exercise give inhaled b agonist first
[lanny] BUT FIRST GIVE B AGONIST INHAKED
[dua_frank] so lets divide these drugs into acute and chronic
[dua_frank] what can you give to control acute attacks?
[lanny] dont rush and oick cromolyncause you see exercise!!!
[dua_frank] yes
[megs] acute..b agonist
[dua_frank] its only to prophylactically prevent exercise asthma
[dua_frank] right megs
[dua_frank] all others can come under chronic management
[lanny] b agonist
[dua_frank] steroids, cromolyn, mast cell inhibits, aminophylline
[dua_frank] how long after do steroids start working?
[lanny] if pt cant take b agonist what can you give???
[samantha] what is given is nocturnal asthma
[megs] salmeterol
[samantha] cough variant?
[dua_frank] depends on it having wheeze or not sammy, might be cardiac
[megs] long acting b agonist
[dua_frank] so be careful dealing with noctornal cough
[samantha] yes rt megs and dua
[megs] in cardiac pt with asthma which drug u preferr??
[samantha] nocturnal or cough variant dua
[dua_frank] pindolol?
[dua_frank] timolol
[dua_frank] something that is lung specific
[megs] ipratropium bromide
[dua_frank] oh :O
[samantha] is it possible it is cardiac?how?dua
[dua_frank] was just guessing sammy, dunno
[samantha] oh...CHF
