question 41. I don’t think you need to read anything more.
Option list.
A.
true
B.
false
C.
don’t be daft
D.
pruritus of pregnancy
with no other explanation which is associated with abnormal LFTs, raised bile
acids and pale stools, all of which resolve postnatally
E.
pruritus of pregnancy
with no other explanation which is associated with abnormal LFTs, ± raised bile
acids and pale stools, all of which resolve postnatally
F.
pruritus of pregnancy
with no other explanation which is associated with abnormal LFTs, ± raised bile
acids, all of which resolve postnatally
G.
pruritus of pregnancy with no other explanation
which is associated with abnormal LFTs (using pregnancy-specific ranges), ±
raised bile acids and pale stools, all of which resolve postnatally
H.

with no other explanation which is associated with abnormal LFTs (using
pregnancy-specific ranges), ± raised bile acids, all of which resolve
postnatally
I.
levels do not usually
rise in pregnancy

mostly originates in

none of the above
Scenario 1.
The international definition of OC was agreed at a
conference in Tokyo in 1985.
Scenario 2.
What is the GTG’s definition of OC?
Scenario 3.
What is the incidence of pruritus in pregnancy?
Scenario 4.
Hepatitis B and C, but not
hepatitis A, may cause pruritus and abnormal LFTs in pregnancy.
Scenario 5.
Infection with the Ebstein Barr
virus may cause pruritus and abnormal LFTs in pregnancy.
Scenario 6.
The cytomegalovirus may cause
pruritus and abnormal LFTs in pregnancy.
Scenario 7.
The herpes zoster virus may
cause pruritus and abnormal LFTs in pregnancy.
Scenario 8.
Chronic active hepatitis and
secondary biliary cirrhosis are included in the GTG’s list of conditions to be
considered in the differential diagnosis.
Scenario 9.
Bilirubin levels are normally
elevated in the early stages of OC and remain elevated until the condition
resolves after delivery.
Scenario 10.
Liver function tests become abnormal as soon as the
pruritus is noted.
Scenario 11.
Levels of bile acids commonly rise significantly after
meals making fasting levels mandatory for diagnosis.
Scenario 12.
The upper limit of normal for transaminases, gamma GT and
bile acids is about 20% lower in pregnancy.
Scenario 13.
Once a diagnosis of OC has been
made, tests of liver function should not be repeated until the puerperium
Scenario 14.
LFTs should be checked weekly
until they have returned to normal after delivery of the baby in a case of OC.
Scenario 15.
Once a diagnosis of OC has been
made, the activated partial thromboplastin time (APTT) should be measured and a
full coagulation screen done if it is prolonged.
Scenario 16.
Delivery at 37 weeks should be
recommended because of the risk of FDIU in the later weeks of pregnancy.
Scenario 17.
What additional pre-labour
monitoring of fetal welfare is advisable in the third trimester?
