Q

stages of coming out

  1. identity confusion
  2. identity comparison
  3. identity tolerance
  4. identity acceptance
  5. identity pride
  6. identity synthesis
A

can be out of order and skip steps

  1. begins to acknowledge, but find unacceptable (make excuses for behavior)
  2. accept but don’t describe self as gay (accept behavior but not identity or vice versa)
  3. accept likelihood, try on identity
  4. move from tolerance to acceptance, anger at society rather than self; choose to be around people that accept them
  5. marches, pride and anger, us against them
  6. begin to understand that not all heterosexuals are homophobic, relax, re-integrate into society
24
Q

important to remember as a doctor when patient is in identity pride stage

A
  1. safe sex

2. don’t Dx with personality disorder, sex addiction, etc.

26
problems with hormone therapy for transgender 1. testosterone 2. estrogen 3. anti-androgens
1. liver damage 2. clotting, increase in BP and blood glucose 3. lower BP, disturb electrolytes, dehydration

``` permission 1st D: description of problem O: onset U: understanding cause P: past attempts at solution or treatment E: expectations for treatment ```
29
recruitment of egg 1. first recruitment 2. second recruitment
selection and growth of dominant follicle 1. paracrine control: AMH 2. endocrine (FSH): AMH, inhibin B and estrogen
30
how can you determine if a women is ovulating?
day 21 of cycle: | progesterone is over 5
31
AMH role in ovarian cycle
paracrine at first, endocrine (FSH driven) at end | primordial to primary oocyte to secondary oocyte to small antrum development
32
Inhibin B role in ovarian cycle
FSH driven | small antrum to dominant follicle
33
estradiol role in ovarian cycle
FSH driven | small antrum to dominant follicle and ovulation
34
When and where do you implant embryo in IVF
uterus: upper posterior | day 3: morula or day 5: blastocyst
35
infertility
1 year of unprotected sex without conception | 6 mo if over 35 yrs
36
``` male factor semen analysis 1. volume 2. conc. 3. motility 4. morphology 5. pH 6. round cells 7. possible reasons for male infertility 8. other factors to evaluate ```
sperm ascend through Cx, Ut, tubes and capacity to fertilize oocyte 1. 1.5-5 ml 2. greater than 20 mil/ ml 3. greater than 40% 4. greater than 14% 5. greater than 7.2 6. less than 1 mil/ml 7. retrograde ejaculation, duct obstruction, hypogonadism, CBAVD 8. karyotype, Y chromosome microdeletions, FSH, LH, PRL, Testosterone
37
cervical factor 1. reasons for infertility 2. tests
Cx filters and nurtures sperm into Ut and tubes 1. anatomical changes, infection, change in mucus 3. culture, post-coital test (see if sperm are moving in cervical mucus)
38
ovarian factor 1. reasons for infertility 2. tests
ovulation of mature oocyte 1. anovulation, luteal phase deficiency 2. menstrual Hx, basal body temp, serum progesteron, urinary LH excretion, basal FSH/clomiphene challenge, oligo-amenorrhea test
39
tubal/peritoneal factor 1. reasons for infertility 2. evaluation
tubes capture oocyte and transport sperm and embryo 1. anatomical changes (congenital, BTL, adhesions, endometriosis) 2. hysterosalpingography, GOLD STANDARD: laparoscopy with chromopertubation, sonohysterography
40
uterine factor 1. reasons of infertility 2. tests
Ut receptive to implantation and support pregnancy 1. anatomical changes (congenital, fibroids, adhesions), functional abnormalities (endometritis) 2. US, sonohysterography, hysterosalphingography, hysteroscopy, occasionally endometrial biopsy
41
Tx of male infertility factor
endocrine Tx | IUI, TDI, ART
42
Tx of infertility female
correct anatomical defects Rx for infection restore regular ovulatory cycles induce ovulation: clomiphene citrate, aromatase inhibitors, gonadotropins
43
assisted reproduction techniques (ART) 1. IUI 2. IVF-ET 3. ICSI
1. intrauterine sperm injection 2. in vitro fertilization and embryo transfer 3. intra-cytoplasmic sperm injection
44
chronic HTN preconception management
1. avoid ACE inhibitors, ARBs 2. teach BP self monitoring 3. diminish diuretic use
45
chronic HTN antepartum evaluation
1. 24 hour urine: total protein and creatinine clearance 2. baseline lab data (CBC, CMP, serum creatinine, LFTs, LDH, uric acid 3. EKG, echocardiogram, ophthalmologic exam 4. if proteinuria disproportionate to HTN: SLE and renal disease workup 5. severe range BP less than 20weeks: hyperaldosteronism, molar pregnancy workup
46
When should you start anti-hypertensives antepartum?
BP greater than 150/100 | weight loss should NOT be encouraged
47
anti-HTN options in pregnancy
1. methyldopa 2. labetalol 3. nifedipine 4. thiazide diuretics 5. hydralizine reduces hospitalization and maternal stroke does NOT improve fetal condition or prevent preeclampsia
48
methyldopa
alpha agonist tx: first line for HTN in pregnancy AE: hepatitis, hemolytic anemia
49
labetalol
beta blocker with alpha blocking activity Tx: second line for HTN in pregnancy does NOT cause IUGR like other beta blocker
50
nifedipine
Ca channel blocker | AE: headache, tachycardia, orthostatic hypotension
51
delivery recommendation for chronic HTN
39 weeks | indications for earlier delivery: preeclampsia, eclampsia, sever HTN beyond 37 wks, fetal compromise
52
DM in pregnancy evaluation
1. urine creatinine, total protein 2. Hemoglobin A1C 3. thyroid function tests 4. urinalysis and urine culture 5. BP and EKG
53
Blood glucose value goals 1. fasting 2. pre-prandial 3. 1 hour post prandial 4. 2 hour post
1. 95 mg/dL 2. 100 or less 3. 140 or less 4. 120 or less
54
DM Tx in pregnancy
BEST: insulin only glyburide metformin increase insulin needs as pregnancy progresses
55
what should be checked in DM pregnancy 1. 20 wks 2. 15-21 wks 3. starting at 32 weeks
1. fetal echocardiogram 2. alpha fetoprotein; neural tube defects 3. serial growth ultrasounds
56
During labor: DM management 1. latent labor 2. active 3. if glucose exceeds 110
insulin night before, hold morning dose since not eating 1. IV saline, monitor blood glucose 2. add 5% dextrose, maintain glucose level of 100, may continue infusion of insulin pump 3. short acting insulin
57
postpartum DM management
maintain glucose below 150 when not eating | HALF antepartum regimen
