20:05:41 [ninadnashua] ll be right back in a while

20:05:49 [hutals] ok

20:11:50 mle1 enters this room

20:12:37 [hutals] hey mle

20:13:19 [hutals] seems empty tonight....i guess its must see thursday or something??

20:13:22 [mle1] hey hutals

20:15:00 [mle1] are we continuing rbc&lymphoprolifertaive sysyem?

20:15:25 [hutals] tonight i think is coagulation and bllod

20:15:28 [mle1] or moving on to coagulation?

20:15:35 [mle1] oh,o.k

20:16:50 [mle1] oh, by the way hutals have you finished studying entire pathology?

20:17:05 [mle1] hope you don't mind me asking this Q

20:17:23 [hutals] not yet....i've been reading along as per the schedule

20:17:38 [mle1] oh,o.k

20:17:54 Lorena enters this room

20:17:55 >[Lorena] Welcome to our chat. Please obey the net etiquette while chatting: try to be pleasant and polite.

20:18:00 [hutals] i'm actually a little behind and hope to catch up this weekend.....how bout you?

20:18:11 [mle1] you guys are reading the <a target=new HREF=http://www.amazon.com/exec/obidos/external-search?tag=valuetheplace-20&keyword=Goljan&mode=books>Goljan</A> review book right?

20:18:23 [mle1] oh,even i'm alot behind.

20:18:31 [Lorena] hi !!

20:18:40 [mle1] takes alot of time to read <a target=new HREF=http://www.amazon.com/exec/obidos/external-search?tag=valuetheplace-20&keyword=Goljan&mode=books>Goljan</A> pathology.

20:18:45 [hutals] hey lor

20:18:58 [mle1] hey lorena

20:18:59 [Lorena] hi guys

20:19:03 [hutals] cant type golijan or it will give a link

20:19:23 [Lorena] jwls cannot make it for today

20:19:27 [hutals] yes, you should try to get your hands on the audio

20:19:28 [mle1] oh,o.k, i was startled for asec.

20:19:47 [hutals] i wont be able to make it tomorrow

20:19:50 [mle1] thanks hutals.

20:20:15 [Lorena] me neither , i have a wedding

20:20:24 [hutals] the audios help alooooottt.....he makes it much easier to follow

20:21:07 [hutals] lucky you lor....love going to weddings

20:21:11 [mle1] oh,o.k.so you guys read the review book along with listening to the audio?

20:21:29 [Lorena] yes, they are nice

20:21:46 [mle1] i downloaded them just afew days back.

20:22:19 [hutals] i personally use the lecture notes that go along with the audio lectures, but the book is very similar.....just a different format

20:23:19 [hutals] then for all the other subjects i'm using the kap notes

20:23:21 [mle1] oh,o.k

20:23:37 [mle1] yes, same here too.

20:24:43 [hutals] i guess we can probably breeze thru some of the coagulation chapter since its not that long and not many of us here....want to get started and try to finish early?

20:25:13 [Lorena] yes

20:25:14 [hutals] nina is here but said she will be back

20:25:38 [Lorena] ok

20:26:00 [Lorena] difference between hemophilia A and B?

20:26:07 [ninadnashua] ya im back

20:26:08 [mle1] o.k

20:26:30 [hutals] factor 8 for A and 9 for B

20:27:11 [Lorena] yes, and with von willebrand disease? clinical not laboratory

20:27:53 [hutals] increased BT in VWD, but normal in hemophilia

20:28:11 [Lorena] yes

20:28:40 [hutals] hmmm, thats labs

20:28:41 [Lorena] also in Von willebrand they rarely have hemarthrosis

20:29:19 [hutals] i didnt know that one lor....thanks'

20:29:42 [Lorena] bleeding time is increased yes , so they bleed from gums or other mucosae

20:30:20 [hutals] ok, after listening to golijan, i think i finally understand the main difference between the extrinsic and intrinsic system. extrinsic has which factor which is not in intrinsic?

20:31:28 [Lorena] thromblopplastin?

20:32:02 [hutals] extrinsic has factor 7 which is unique, so that is the magic number to know

20:32:28 [hutals] intrinsic has 12, 11,9,8 unique

20:32:29 [Lorena] oh ok, the lucky number

20:33:06 [hutals] yes, i meant lucky, not magic...sorry

20:34:17 [Lorena] what factors are affected by heparin?

20:34:17 [hutals] so in hemophilia A which pathway?

20:34:39 [Lorena] intrinsic because it is VIII factor

20:34:57 [hutals] exactly, same would be true for hemophila B

20:35:20 [hutals] now here is a tricky concept

20:35:37 [hutals] they both share 10, 5, 2, 1

20:36:25 [Lorena] ok

20:36:26 [hutals] warfarin and heparin will effect factors in BOTH systems, but one more than other

20:37:09 [hutals] so knowing that, what would be affected with those....extrinsic or intrinsic

20:37:32 [Lorena] heparin affects more factors than warfarin right?

20:37:58 [hutals] yes thats correct

20:38:35 [hutals] heparin will effect intrinsic more uniquely, but also extrinsic

20:38:46 [hutals] opposite for warfarin

20:39:01 [hutals] PT goes with extrinsic and PTT with intrinsic

20:39:10 [Lorena] yes

20:39:16 [hutals] so here is the trick question that might be asked

20:39:21 [Lorena] which extrinsic affects heparin?

20:39:50 [hutals] what would you expect as far PT and PTT for heparin, what about warfarin?

20:40:25 [hutals] the shared ones.....2

20:41:06 [hutals] shared factors are 10, 5, 2, 1. the factors for heparin are 2, 7, 9, 10

20:41:15 [Lorena] warfarin prolonged PT , heparin prolonged PT and PTT?

20:41:18 Betty31 enters this room

20:41:39 [hutals] so 2 and 10 will affect both extrinsic and intrinsic

20:41:44 [hutals] hey betty

20:42:03 [Lorena] hi betty

20:42:06 [Betty31] hi

20:42:42 [hutals] actually, both will have an increased PT and PTT. But PT better indicator for warfarin and PTT better for heparin.

20:43:05 [Lorena] ok, thanx

20:43:57 [hutals] that always threw me off because when i would see an increase in both, i would exlude those two causes.....but i was wrong.....but now i finally figured it out thanks to papi

20:44:43 [Lorena] and me thanks to you

20:44:54 [hutals]

20:45:40 [hutals] what a common cause of HUS?

20:46:05 [hutals] hint-round in undercooked meat

20:46:15 [hutals] not round....found

20:46:25 [Lorena] escherichia coli Enterohemorragica

20:46:47 [hutals] yep E coli 0157:H7

20:46:59 [hutals] another one is shigella

20:47:17 [hutals] what the most common cause of an inc BT

20:47:41 [hutals] hint - you can buy it over the counter

20:48:31 [hutals] another hint is that its used for headaches and causes ulcers

20:48:34 [Lorena] it would be aspirin

20:48:49 [hutals] yep

20:49:21 [Lorena] what does bleeding time test?

20:49:42 [hutals] PLT function

20:49:52 [Lorena] yes

20:50:11 [hutals] what is a common cause of vit k def?

20:50:38 [Lorena] broad spectrum antibiotics, malabsorption

20:51:04 [hutals] antibx, newborns, warfarin, malabsorption......good job!

20:51:26 [hutals] in preg pt, would you give heparin or warfarin?

20:51:51 [Lorena] heparin

20:52:17 [hutals] yep....."war is bad"

20:53:10 [Lorena] why baby can have a def in vit K?

20:53:42 [hutals] no normal flora so require IM vit K at birth

20:53:57 [Lorena] yes

20:54:05 [ninadnashua] no vit k in breast milk

20:54:07 [hutals] look for newborn born at home as hint on exam

20:54:11 [hutals]

20:54:27 [hutals] good point nina

20:54:28 [ninadnashua] so require im vitk

20:55:00 [ninadnashua] thanks

20:55:20 [hutals] pt has diffuse oozing of blood from all breaks in skin shortly after delievery. labs detect inc D-dimers, inc PT and PTT, dec PLTs, shistocytes seen....diagnosis

20:55:52 [Lorena] ICD

20:56:29 [hutals] i know it as DIC, but probably the same thing.....right?

20:56:48 [Lorena] ops, sorry i meant DIC

20:56:53 [Lorena] lol

20:57:10 [hutals] no prob....i figured that

20:57:34 [hutals] the pt probably had an amniotic fluid embolism

20:57:44 [Lorena] yes

20:58:05 [hutals] the D dimer is typically known for detecting PE's, but also known for DIC

20:58:21 [hutals] treatment?

20:59:09 [Lorena] treat the underline pathology, heparin

20:59:20 [hutals] yep, very good

20:59:34 [Lorena] to avoid consumption of coagulation factors and plasma

21:00:27 [Lorena] what are other causes of DIC?

21:00:38 [hutals] seems crazy to give heparin to someone who is already bleeding, so that is a board favorite because it goes against logic unless you understand the process

21:00:54 [hutals] endotoxic shock

21:01:08 [hutals] snake bites

21:01:20 [Lorena] yes very good

21:01:58 [hutals] i think we actually covered most of coagulation....that was a short chapter

21:02:15 [Lorena] yes

21:02:51 [hutals] wanna call it quits early since we covered the material and not to many showed up tonight?

21:03:14 [Lorena] yes, good idea

21:03:37 [Lorena] i'll see you all on monday

21:03:44 [hutals] ok, well have a great time at the wedding and have a great weekend!

21:04:06 [Lorena] thank you hutals you too!
