Q

Amenorrhoea classification?

A
  1. Primary = by 15 y/o with normal secondary sexual characteristics, or by 13 y/o with no secondary sexual characteristics
  2. Secondary = cessation for 3-6m in women with previously normal menses, or 6-12 months with previous oligomenorrhoea

Q

Premenopausal women cyst management?

A

A conservative approach may be taken for younger women (especially if < 35 years) as malignancy is less common. If the cyst is small (e.g. < 5 cm) and reported as ‘simple’ then it is highly likely to be benign. A repeat ultrasound should be arranged for 8-12 weeks and referral considered if it persists.

Q

Ovarian hyperstimulation syndrome?

A

Ovarian hyperstimulation syndrome (OHSS) is a complication seen in some forms of infertility treatment. It is postulated that the presence of multiple luteinized cysts within the ovaries results in high levels of not only oestrogens and progesterone but also vasoactive substances such as vascular endothelial growth factor (VEGF). This results in increased membrane permeability and loss of fluid from the intravascular compartment

Q

Mittelschmerz mushkies?

A

Mittelschmerz literally translates to ‘middle pain’ and refers to abdominal pain associated with ovulation. This mid-cyclical pain is experienced by 20% of women and there are several theories as to why it occurs. One explanation is that is occurs due to a leakage of follicular fluid containing prostaglandins at the time of ovulation, which causes the pain. Another explanation is that the growth of the follicle stretches the surface of the ovary, causing pain

Q

PCOS mushkies?

A

Polycystic ovarian syndrome (PCOS) is a complex condition of ovarian dysfunction thought to affect between 5-20% of women of reproductive age. Management is complicated and problem based partly because the aetiology of PCOS is not fully understood. Both hyperinsulinaemia and high levels of luteinizing hormone are seen in PCOS and there appears to be some overlap with the metabolic syndrome.

115
Q

Body temperature rises when in menstrual cycle?

A

Following ovulation

116
Q

Menstrual cycle phases?

A
  1. Days 1-4 = Menstruation
  2. Days 5-13 = Follicular (proliferative) phase
  3. Day 14 = Ovulation
  4. Days 15-28 = Luteal (secretory) phase
117
Q

Follicular (proliferative) phase mushkies?

A
  1. Number of follicles develop, one will become dominant around mid-follicular phase
  2. Proliferation of endometrium
  3. Rise in FSH results in development of follicles which in turn secrete oestradiol. When the egg has matured, it secretes enough oestradiol to trigger the acute release of LH. This in turn leads to ovulation
  4. Following menstruation the cervical mucus is thick and forms a plug across the external os. Just prior to ovulation the mucus becomes clear, acellular, low viscosity. It also becomes ‘stretchy’ - a quality termed spinnbarkeit
  5. Basal body temperature falls prior to ovulation due to the influence of oestradiol
118
Q

Luteal (secretory) phase mushkies?

A
  1. Corpus luteum present
  2. Endometrium changes to secretory lining under influence of progesterone
  3. Progesterone secreted by corpus luteum rises through the luteal phase. If fertilisation does not occur the corpus luteum will degenerate and progesterone levels fall. Oestradiol levels also rise again during the luteal phase.
  4. Under influence of progesterone, cervical mucus becomes thick, scant and tacky
  5. Temperature rises following ovulation in response to higher progesterone levels
