Q

What history would confirm ovulatory cycles?

A

Q

Ovarian reserve testing

A
  • quantity and quality are both important factors! - oocyte number peaks at 20 weeks gestation, this declines throughout reproductive life resulting in menopause - routine markers: day 2-4 FSH, E2, AMH and assessment of antral follicle count on TV ultrasound - provides information r.e. predicted response to assisted reproductive treatment - does not predict spontaneous conception!

Q

Day 2-4 (basal) FSH as measure for ovarian reserve

A
  • indirect marker of ovarian reserve - based on feedback inhibition of pituitary FSH secretion - if diminished ovarian reserve ovarian steroidogenesis will be insufficient to suppress early follicular FSH - measurement of E2 increases FSH sensitivity - E2 will be raised with low ovarian reserve due to increased FSH but causes pituitary FSH suppression meaning FSH falls within normal range

Q

Where is AMH produced?

A
  • by granulosa cells of the pre-antral and antral follicles - hence reflexes the size of primordial follicle pool - serum AMH concentration is inversely related to age - can be tested on any day of cycle

Q

What are the 3 main recommendations when caring for a victum of sexual assault?

A
  1. Offer first-line support to women and men who are survivors of sexual assault by any perpetrator 2. Consider and ask about post trauma responses by assessing for mental health problems – acute stress, PTSD depression, alcohol and drug use problems, suicidality or self-harm and offering appropriate support and treatment 3. Offer emergency contraception if within 72 hours of assault and offer all women sexually transmitted infection investigation, prophylaxis and treatment as appropriate

A

Day 14

127
Q

What is day 1 of the cycle?

A

1st day of menstruation

128
Q

Follicular phase

A

DAY 1 - DAY 14 - first part of the ovarian cycle and ends with completion of antral follicles - generally lasts ~14 days but shortens with age - rise in FSH in first few days of cycle causing ovarian follicles to be stimulated - LH then further stimulates development of the follicle - oestrogen is then released causing a FSH and LH surge which usually occurs 1-2 days before ovulation - this stimulates rupture of antral follicle and release of oocyte

129
Q

Ovulation

A

DAY 14 - LH surge initiates ovulation and stimulates formation of the corpus luteum - the CL then produces and releases estrogen, progresterone, relaxin and inhibin

130
Q

Luteal phase

A

DAY 14-28 - final phase of the ovarian cycle - corresponds to the secretory phase of the endometrium - FSH asnd LH cause remaining part of the dominant follicle to turn into the corpus luteum which releases progesterone - progesterone increase induces oestrogen production - falling levels of progesterone cause menstruation and the begining of the next cycle

-

165
Q

Patient education r.e. CST

A

• the link between persistent HPV infection and cervical cancer, noting – HPV infections are usually cleared by the immune system in 1–2 years – if infection persists, in rare cases it can lead to development of cervical cancer after about 10–15 years • cervical screening is based on HPV testing, and that cells in the sample will only be studied for changes if HPV is detected • the sample collection procedure is similar to the previous Pap test • patients are invited to start cervical screening from the age of 25 and continue screening until they are 74 years old • screening is only required once every five years for patients who do not have HPV detected

166

<12mm if pre menopausal or <5mm if peri-menopausal = conservative treatment and monitoring

>12 mm if pre menopausal or >5 if perimenpausal = referral for endometrial biopsy

184
Q

Management of post menopausal bleeding

A
  • exclude cervical pathology: CST +/- chlamydia
  • FBC if indicated
  • if on tamoxifen –> refer to gynaecologist and referal for US, will require endometrial biopsy

A

Retractability increases with age

Full retraction seen…

> in 10% of boys at 1

> 50% of boys at 10

> 99% of boys at 17

  • a non retractable foreskin is a normal variant and doesn’t require intervention
  • should never be forcibly retracted for cleaning!
217
Q

“Ballooning” in boys

A
  • some kids will notice this with non-retractable foreskins
  • ballooning will occur during urination
  • may increase risk of balanitis but usually on no-consequence
  • treat if problematic: topical steroid cream sparingingly (0.05% betamethasone TDS for 6-12 weeks)
218
Q

RCH: inflammation and balanitis

A
  • mild redness and soreness of top is common can can be managed with reassurance
  • if extensive inflammation of glans penis +/- foreskin = balanitis

  • treatment: warm salt water, barrier or 1% hydrocortisone cream, antifungal cream if suspect candida (clotrimazole/miconazole)
219
Q

RCH: penile infection and cellulitis

A
  • oral antibiotics: flucloxacillin
  • GAS can causes severe genital rash that is weeping and raw
220
Q

Phimosis

A
  • pathological phimosis results from scarring of the preputial ring, preventing retraction
  • obvious ring of scar tissue, foreskin not retractiable at conclusion of puberty
  • previously retractable foreskin now not retractable
  • persistent ballooning of foreskin in older children
  • causes: BXO or most commonly due to repeated forcible attempts to retract foreskin
  • treatment: steroid for 2-4 weeks if good response continue for 6-12 (0.05% betamethasone)
221
Q

Paraphimosis

A

Urological emergency

  • risk pof preputial necrosis

METFORMIN IR 500mg nocte, up to 150mg daily in 2-3 doses

228
Q

Approach to heavy menstrual bleeding

A
  • exclude pregnancy, perform CST if due
  • initial examination and investigation (FBC, ferritin, coagulation profile and TSH)

  • if nil of above –> suggest contraception (LNG-IUG/COC) +/- TXA or NSAID
229
Q

Non-hormonal management of heavy menstrual bleeding

A
  • TXA 1-1.5g orally for first 3-5 days ofr cycle (Q6-8H)
  • ibuprofen/mefenamic acid/naproxen
230
Q

Male androgen deficiency

A
  • impaired testosterone production due to proven dyfunction in the hypothalamic-pituitary-testciular axis
  • male hypogonadism is androgen deficiency with impaired fertility
  • > hypergonadotrophic: primary testicular disorders
  • > hypogonadotrophic: central hypothalamic/pituitary disorder

CAUSES

  • Primary: Klinefleter (47XXY), cryotochidism, orchidectomy, orchitis, raidatyion, torsion, trauma, androgen synthesis inhibitors
  • Secondary: pituitary tumours, pituitary surgery/radiotherapy, haemochromatosis, hypophysitis, idiopathic hypogonadotrophic hypogonadism (Kallmann syndrome)

DDx for central causes: exogenous syntheic andorgen use, recent acute illness, functionally low testosterone concentrations

231
Q

Approahc to diagnosis of suspected male androgen deficiency

A
  • measure fasting morning serum total testosterone concentration
  • if low: repeat morning total testosterone with serum FSH and LH
  • if low testosterone but high LH: primary androgen deficiency
  • if low testosterone band low or normal LH and FSH: central androgen deficiency
232
Q

Precocious puberty

A
  • pubertal development is unusual in females younger than 8 and males younger than 9
  • early onset of puberty is either gonadotrophin dependent (central) or independent
  • central precocious pubert: breast development in females younger than 8 and testicular enlargement in males younger than 9 (often idiopathic but can be caused by brain lesions)
  • gonadotrophin independent early puberty is much less common: can cause feminisation of males or virilisation of females, causes include ovarian cycts, tumours, testicular stomal or germ cell tumours
  • precocious puberty more common in females and usually idiopathic however in males is more likely to be pathological
233
Q

Masculinising hormones: testosterone

A
  • aim: to reduce gender dyphoria
