How does the combined pill work as a contraceptive?
Combined synthetic oestrogen and progesterone - prevents ovulation, thins lining of uterus and thickens cervical mucus. Monophasic keeps hormones at constant level throughout cycle = 1st line
How should the COCP be taken?
Same time every day. Start on day 1 of cycle
Some pills for 21 days, with 7 day break
But some can be taken back-to-back until breakthrough bleed. Then should stop for 4 days
What should be done if 1 or 2 COCP doses are missed?
Take the last pill you missed, even if it means taking 2 in one day
Carry on the rest of pack as normal
If missed 2 or more doses, risk of pregnancy

Patient should check in place after 1st month and after every period - if threads present
What are the risks with the IUD?
Perforation
Pelvic infection (should do pelvic exam before inserting to check for local infection/STI) in first 20 days
May be unethical for some as prevents implantation of embryo - abortion?
How does the IUS work?
T-shaped plastic device inserted into uterus
Releases progestogen

In LFTs, what enzymes are:
a) hepatocellular?
b) biliary?
c) pancreatic?
a) AST + ALT
b) ALP + GGT
c) amylase + lipase
What does raised AST but normal ALT indicate and why?
Problem elsewhere (not liver) - think MUSCLE, check CK AST produced by bone, muscle, heart, brain, RBC, not just liver, whereas ALT is specific to liver
What does a raised ALP but normal GGT suggest?
Not biliary problem, think elsewhere e.g. BONE
ALP produced bone, kidney, GIT, placenta, but GGT is specific to biliary + ALCOHOL use
What does a raised amylase but normal lipase suggest?
Not pancreatic cause, as amylase produced in saliva too, whereas lipase only produced in pancreas

b) alcoholic fatty liver disease?
a) ALT>AST
b) AST>ALT
