all these were asked as MCQs in nov 2009 aiims
so have a very high chance of repeat this year
remember all these points
1) most common cause of neonatal sepsis in india = klebsiella > staphylococcus aureus > pseudomonas > e.coli.
2)cranial nerve ,which on stimulation ,elevates mood = vagus nerve.
3)most useful investigation for diagnosis for ectopic pregnancy = transvaginal USG.
4)tocolytic of choice in heart disease = atosiban.
5)best time for surgery of orchidopexy = 6-12 months.
6)best treatment for desmoid tumour = wide excision followed by radiotherapy.
7)full thickness graft is not taken from axilla.
8)in hyperkalemia without ECG changes,no need of giving calcium gluconate in treatment.
9)type of anaemia in intestinal tuberculosis = megaloblastic anaemia.
10)cryoprecipitate transfusion does not require ABO cross matching.
11)most sensitive investigation for myasthenia gravis = single fibre EMG.
12)most common cause of Subarachnoid haemorrhage = HEAD TRAUMA >aneurysmal rupture.
13)most common progestin used for emergency contraception = levonorgesterol.
14)OPV is a live attenuated vaccine.
15)thinnest part of sclera is behind the insertion of rectus muscle.

Drug used in intrahepatic cholistasis?antihistamin/ursodiol/cholistyramin.
ReplyDeleteantihistamin
DeleteCommon cvs anomalyin DM IN prgn.vsd/tga?
ReplyDelete@dr.pawan...i have answered intrahepatic cholestasis ques in a separate post...plzzz check it out
ReplyDeletei will post anomalies associated with DM asas...got to go somewhere right now
ReplyDeletethanx for your active participation in discussion here....
discussion always helps
keep working hard :)
There 1 qus. on down synd. in aipg2010...matrnal/patrnal...?what is that?
ReplyDeleteAIPG 2010 ques) which of the following is most commonly associated with pathogenesis of down's syndrome?
ReplyDeletea)maternal nondysjunction
b)paternal nondysjunction
c)mosaicism
d)robertsonian translocation
answer is A) maternal nondysjunction
Qus 186 of aipg2005 snsitiv tst for MG is endrophonium tst.singl fibr emg is nt snsitiv?
ReplyDelete@drpawan...dr.saab answer in mudit khanna is wrong...answer to that ques is single fibre electromyography( SFEMG)..
ReplyDeletemudit khanna has not said SFEMG is not sensitive
it only said that it is not used as an initial test...
but look at the chart given in mudit khanna,,,even in chart it says that SFEMG is a confirmatory test...
this SFEMG as most sensitive has been discussed thoroughly on rxpg...
remember MOST SENSITIVE IN MYASTHENIA = sfEMG
most specific = anti acetylcholine receptor antibodies
dear most common cause of subarachnoid haemorrhage is trauma followed by aneurysm see Q NO.77 DEC 1998....... I M NT SURE.. MAY B DAT REFERENCE IS WRONG..... LET ME KNOW
ReplyDeletemost common cause of SAH is trauma> aneurysm..c aiims dec 77 Q...... LET ME KNOW
ReplyDelete@gaurav..you are right
ReplyDeletemost common cause of SAH overall= head trauma
usually traumatic SAH is considered a separate entity...
most common cause of spontaneous SAH = aneurysmal rupture
but overall i agree = TRAUMA
i will update the answer
thanx
good work
For Myasth quest.
ReplyDeleteExact quote from MK "Confirmatory but not specific". Nothing said about sensitivity.
Sensitivity of Edrophonium is higher esp. if ocular musc involv.
Therefore edrophonium should be the ans.
After my earlier post I searched net and now differ from my earlier ans.
ReplyDeleteRef - http://neuromuscular.wustl.edu/mtime/mgdx.html
Utility of Tensilon test
Only useful in patients with objective, preferably measurable, findings on physical examination
Rarely helpful in the diagnostic evaluation of equivocal cases of MG
Sensitivity for MG is relatively low (60%) compared to other diagnostic tests
Tensilon testing should not be used to determine adjustments in the dose of pyridostigmine
False positive results
Can occur in patients with LES, ALS or even localized, intracranial mass lesions
Positive testing does not necessarily predict respose to a longer-acting anti-AChE drug
SFEMG is the most sensitive test for MG
Sensitivity: > 95% positive in generalized & ocular MG
When the test site includes facial muscles
Abnormal jitter is not specific for MG
May occur in other neuromuscular disorders, including ALS, polymyositis or LEMS
More specific for MG if large degree of jitter occurs with mild or no other changes on EMG
Another ref - http://en.wikipedia.org/wiki/Myasthenia_gravis
he "edrophonium test" is infrequently performed to identify MG; its application is limited to the situation when other investigations do not yield a conclusive diagnosis
In single fiber electromyography, which is considered to be the most sensitive (although not the most specific) test for MG.
Now the question arises ----
ReplyDeleteIf Choices are
a. Edrophonium test
b. EMG (not Single fibre EMG)
What should be marked? EMG I guess... What say?
@varun....yes u guessed right
ReplyDeleteEMG would still be the better answer :)
