Q

Most likely causes of Erectile Dysfunction? (Sorry I don’t know why this is in obs/gyne)

A

Psychosomatic, vascular pathology (diabetes, HTN), medication side effect (SSRIs, SNRIs, benzodiazepines, antipsychotics, anti-epileptics (gabapentin), hormonal chemotherapy, possibly OCP)

Low testosterone is not usually the cause unless very seriously low - and then would see other symptoms.

Q

Bishops score?

A

Cervical measurement:

Station (3- to +3), effacement (as a % - 0% = long, 100% = paper thin), dilation (0 - 10cm), position (relative to the fetal head and maternal pelvis), consistency (firm vs soft) - over >8 is go time for labour or induction, less than 6 not favourable - consider cervical ripening.

Fetal variables

A

Size, lie(longitudinal, oblique, transverse - must do a c-section), presentation (what is showing first- sutures - compare ocuput compared to mom), attitude, position (where the anterior suture is - most are LOA or ROA and OA everything that are correct position), station (plus - on its way or minus based on ischial spines)

23
Q

Fetal movements amount?

A

Should have at least 6 movements/ 2hrs - and emergency if decreased movements or sudden cessation.

24
Q

Interpretation of FHR?

A

Baseline (110-160), variability (want moderate), accelerations (should be there esp with contractions), decelerations (early decels are ok - all others are not)

25
Interventions for abnormal FHR
Change maternal position (left lateral decubitus position), discontinue oxytocin infusion, maternal vital signs, take a look - do a vaginal exam (how far is the baby - are they coming along well - where is the cord), consider expedited delivery, aminoinfusion (theoretically), can try fluids
26
Causes of antepartum hemorrhage
Placenta previa - placenta blocks the cervical os, painless bleeding, no vaginal exam. Dx via U/S, can improve, may need c-section. MUST NOT GO INTO LABOUR. Placenta abrupta - premature separation of implanted placenta, painful bleeding, small bleed common, complete is stillbirth,
27
Pregnancy and asymptomatic bacteria?
Treat! Amoxicillin.
28
Polyhydraminos why?
We don’t know, or the babies have renal problems
29
Rupture of membranes - have to deliver baby soon
24-48 hours to avoid infection
30
Cervical cerclage
For incompetent cervix - sew them up and you need to make sure it is cut BEFORE they start labouring. Multips, genetics, surgical?
31
PPROM
Premature rupture of membranes and not in labour, NO BIMANUAL, expectant management. Test the nitrite stick.
32
Big head? Little mom?
CPD, remember power, passenger, passage, psyche
33
Post partum haemorrhage
Tone (uterine atony), tissue (retained placenta), trauma (laceration, uterine rupture), thrombin (coagulopathies) ABC - crystalloids, cross and type for 4 units of blood pRBC, MASSAGE, oxytocin, ergotamine, hemabate, thrombin, ballon tamponade, hysterectomy as final solution.
34
Post-partum pyrexia
B-5W - wind (pneumonia), water (UTI), wound, walking, breast (mastitis - not a reason to stop breast feeding), womb (endometritus **)
35
Risk for endometrial CA?
Unopposed estrogen - age, nulliparity, obesity, PCOS, HRT
36
Clue cells?
Bacterial vaginosis
37
Work up for secondary amenorrhea?
What age are they? Are they pregnant? Urine pregnancy test. TSH, Prolactin, FSH
38
Fitz-Hugh-Curtis Sydrome?
pelvic adhesions secondary to PID, often adhesions also found on liver. Favourite of Dr. Waja’s.
39
Ways to induce labour?
Cervidil (ribbon - insert and leave it), progesterone cream (more frequent application needed), Foley catheter with balloon, and misoprostol (oral or per vagina)
40
Cervidil indications/ contraindications?
To start or continue the ripening of the cervix in pregnant women who are at or near the time of labour. Should not be received by women experiencing unexplained vaginal bleeding, already receiving medications to induce labour, birth more than 6 times AND if baby is in distress and need URGENT delivery, not favourable for vaginal delivery) . Risks primarily of hyperactivation of labour resulting in fetal distress and leading to c-section. Always a minimal risk of DIC
41
Abnormal uterine bleeding cause?
First rule out organic cause - fibroids, adenomyosis, ectopic, endometriosis, medications, etc. Then consider dysfunctional uterine bleeding
42
Why more cramping/ contractions in the summer/ hot weather?
When a person is dehydrated the posterior pituitary produces ADH, this will reduce the output of the kidneys. The posterior pituitary also produces oxytocin, ADH and oxytocin look very similar, so an excess of ADH can act on the uterus and induce cramping in the same way. The reverse is also true - oxytocin excess can also lead to ++ water retention.
43
Free fluid in pelvis, minimal
There is allowed to be - the peritoneum produces around 30-40 mLs a day
44
Ectopic - how high can the bHCG before can’t use methotrexate?
No more than 5000
45
Distension and discomfort abdominal post operative - but no true ileum/ SBO
Get them to walk around, chew gum and try to reduce the amount of narcotics they are on.
46
What can fibroids secrete to try and preserve blood supply?
EPO (like the kidney)
47
HPV strains of concern?
6, 11 - venereal warts 16, 18 - cancer causing 90% - cancers caused by HPV
48
HPV + what causes cervical cancer
Chronic HPV + smoking, HIV, immunocompromised, multiple sexual partners Young people can clear without trouble. See in the 50s and in young people. NEED TIME.
49
Who gets HPV testing?
>30, and has ASCUS pap, it is a reflex order (they test the liquid) Usually about 60-80 dollars
50
Vag pap?
No cervix, hx of cancer - use the brush and the highest point of the vaginal wall. Do every 5 years.
51
What makes the transformation zone come out?
Estrogen makes the transition zone come down more, lack of it makes it recede into the os If you can’t see it, don’t panic, it’s ok, not essential to get transition zone. Unless they have a history of abnormal cells.
52
Ectropion of the cervix?
Normal, redness around the os, multiple sexual partners, more estrogen warn about spotting, still do the pap. Can cause post-coital bleeding - if it is persistent refer to gyne
53
What is a nabothan follicles
The pH of the cervix can lead to more squamous cells, this is just a retention cyst from the mucus of the cervix with the squamous cells growing over the columnar
54
Endocervical polyps
Comes out of the os, tissue can bleed a lot, benign from up in the uterus is endometrial - refer to gyne for removal
55
Things that make paps not adequate?
Bleeding, ++mucus, sex in the last 24 hours, ++lubrication, douches Missed the cervix, no cervix, bad technique
56
Pap results
NILM - all good Absent transformation zone - its ok unless other concerns Squamous - ASCUS (less than 30 - repeat in 6 months - then gyne if abnormal), (>30, can repeat in 6 months or do the testing - if abnormal gyne, if normal go back to 3years), ASC-H (need biopsy - CIN 2,3), LSIL (like ASUS - but still 6months twice, CIN 1), HSIL (need biopsy - CIN 2,3) Biopsy: CIN (1,2,3) - looking at the epithelium and the depth involved, 60% clear for CIN1, for 2 and 3 5% to 12% risk of CA. Glandular (goes to GYNE) Endometrial cells - depends on where they are in cycle - are they post-menopausal? Then gyne.
57
HPV vaccine?
Have to repeat the whole series if only got Gard-4 After high school - need 3 doses Less than that only need 2 Of the gard 9 $160 per shot, 2months, 6 to 12 months (or longer)
