Q

What are the pathological causes of abnormal PV discharge?

A

Causes:
-non-infective: polyps; foreign body; fistula; cancer; atrophic vaginitis (menopause)
Infective:
-non-STI - BV (green-white, fishy) - more sexually active
-candida (cottage cheese white, thick)
-STI: chlamydia (purulent); gonorrhoea (purulent); trichomoniasis (offensive, yellow, profuse, frothy, associated other sx eg pain, itch)
-children: with birth; otherwise suspect possible abuse

A

tier 1 = most effective: coil and sterilisation

tier 2= less effective, other hormonal mx

52
Q

What is the mechanism of action for the COCP?

A

inhibits ovulation via stopping negative feedback loop of oestrogen and prog to hypothalamus so no LH surge and no ovulation and: endometrium thinned so blastocyst can implant, mucus thicker so harder for sperm to enter

A

Monophasic: These pills deliver the same amount of estrogen and progestin each day for 21 days. In the final week, you either take no pills or placebo pills.

60
Q

How does POP work?

A

Desogestrel POP works mainly by inhibiting ovulation. It also works by thickening cervical mucus and thinning the endometrium.
Norethisterone and levonorgestrel POPs work mainly by thickening cervical mucus and thinning the endometrium. These POPs are taken much less commonly as they should be taken within the same 3 hours every day to be effective.

61

A

less endometrial cancer risk, lower risk than COCP for certain things

62
Q

Cons of POP?

Missed pills can have 12 hr window but some are 3 hr window
back to back, no bleeds so harder to tell if pregnant, increased risk ovarian cysts and breast cancer, random bleeding, same as above

CI: breast cancer, liver problems, higher weight, CVD

64
Q

is the implant combined or progesterone only?

Q

CI of implant?

A

CI: pregnant, liver tumour, breast cancer

Q

How does DMPA injection work?

A

eg depot provera : inhibits ovulation and thicken mucus

69
Q

What are the pros of the injection?

A

Pros: v effective, no known interactions, reduce risk endometrial cancer

70
Q

What are the cons of injection?

A

Conns: CAN TAKE A YEAR for fertility to return to normal when finish, breast cancer risk, risk of bone loss, random patterns of bleeding, weat gain

71
Q

CI to injection?

A

CI: breast cancer, pregnant, DM, if want child soonish

72
Q

How does morning after pill work?

A

-levonorgestrel or ulipristal acetate → delay ovulation by enough time for sperm to die and be non-viable

73
Q

emergency contracpetive alternative to morning after pill?

A

Copper coil - 5 days after kills the sperm

74
Q

Difference between fraser and gillick competence?

A

Fraser are for contraception and sexual health

A

Contraceptives - time until effective (if not first day period):
instant: IUD
2 days: POP
7 days: COC, injection, implant, IUS

77
Q

Up to what point can the IUD be inserted as an emergency contraceptive

A

The copper intrauterine device can be inserted for emergency contraception within 5 days after the first unprotected sexual intercourse in a cycle, or within 5 days of the earliest estimated date of ovulation, whichever is later

78
Q

At what point can you become pregnant postpartum?

A

After 21 days - is thought women will ovulate at earliest 28 days post-partum and sperm can survive up to 7 days

79
Q

list some ABSOLUTE CI to the COCP

A 
Migraine with aura
Breastfeeding <6 weeks post-partum
Age 35 or over smoking 15 or more cigarettes/day
Systolic 160mmHg or diastolic 95mmHg
Vascular disease
History of VTE

Complicated valvular and congenital heart disease
Current breast cancer
Nephropathy/retinopathy/neuropathy
Other vascular disease
Severe (decompensated) cirrhosis
Hepatocellular adenoma
Hepatoma
Raynaud's disease with lupus anticoagulant
Positive antiphospholipid antibodies
80
Q

What action should be done if one COCP is missed? what about two?

A

If 1 pill is missed
take the last pill even if it means taking two pills in one day and then continue taking pills daily, one each day
no additional contraceptive protection needed

If 2 or more pills missed
take the last pill even if it means taking two pills in one day, leave any earlier missed pills and then continue taking pills daily, one each day
the women should use condoms or abstain from sex until she has taken pills for 7 days in a row. FSRH: ‘This advice may be overcautious in the second and third weeks, but the advice is a backup in the event that further pills are missed’
if pills are missed in week 1 (Days 1-7): emergency contraception should be considered if she had unprotected sex in the pill-free interval or in week 1
if pills are missed in week 2 (Days 8-14): after seven consecutive days of taking the COC there is no need for emergency contraception
if pills are missed in week 3 (Days 15-21): she should finish the pills in her current pack and start a new pack the next day; thus omitting the pill free interval

81
Q

What action should be taken if the POP is missed?

A 
traditional - if more than 3 hrs later take the missed pill as soon as possible (if desogestrel is 12 hrs). If more than one pill has been missed just take one pill. Take the next pill at the usual time, which may mean taking two pills in one day
continue with rest of pack
extra precautions (e.g. condoms) should be used until pill taking has been re-established for 48 hours
82
Q

mechanism of action for contraceptives

A

COCP - Inhibits ovulation

POP- (excluding desogestrel) Thickens cervical mucus
Desogestrel-only pill Primary: Inhibits ovulation
Also: thickens cervical mucus

Injectable contraceptive (medroxyprogesterone acetate) Primary: Inhibits ovulation
Also: thickens cervical mucus
Implantable contraceptive

(etonogestrel) Primary: Inhibits ovulation
Also: thickens cervical mucus

IUD -Decreases sperm motility and survival

IUS - Primary: Prevents endometrial proliferation
Also: Thickens cervical mucus
