Gynaecology Flashcards
(308 cards)
causes of primary amenorrhoea
Abnormal functioning of the hypothalamus or pituitary gland (hypogonadotropic hypogonadism)
Abnormal functioning of the gonads (hypergonadotropic hypogonadism)
Imperforate hymen or other structural pathology
causes of secondary amenorrhoea
Pregnancy (the most common cause)
Menopause
Physiological stress due to excessive exercise, low body weight, chronic disease or psychosocial factors
Polycystic ovarian syndrome
Medications, such as hormonal contraceptives
Premature ovarian insufficiency (menopause before 40 years)
Thyroid hormone abnormalities (hyper or hypothyroid)
Excessive prolactin, from a prolactinoma
Cushing’s syndrome
irregular menstruation causes
Extremes of reproductive age (early periods or perimenopause)
Polycystic ovarian syndrome
Physiological stress (excessive exercise, low body weight, chronic disease and psychosocial factors)
Medications, particularly progesterone only contraception, antidepressants and antipsychotics
Hormonal imbalances, such as thyroid abnormalities, Cushing’s syndrome and high prolactin
causes of intermenstrual bleeding
Hormonal contraception
Cervical ectropion, polyps or cancer
Sexually transmitted infection
Endometrial polyps or cancer
Vaginal pathology, including cancers
Pregnancy
Ovulation can cause spotting in some women
Medications, such as SSRIs and anticoagulants
causes of dysmenorrhoea
Primary dysmenorrhoea (no underlying pathology)
Endometriosis or adenomyosis
Fibroids
Pelvic inflammatory disease
Copper coil
Cervical or ovarian cancer
causes of menorrhagia
Dysfunctional uterine bleeding (no identifiable cause)
Extremes of reproductive age
Fibroids
Endometriosis and adenomyosis
Pelvic inflammatory disease (infection)
Contraceptives, particularly the copper coil
Anticoagulant medications
Bleeding disorders (e.g. Von Willebrand disease)
Endocrine disorders (diabetes and hypothyroidism)
Connective tissue disorders
Endometrial hyperplasia or cance
Polycystic ovarian syndrome
causes of postcoital bleeding
Cervical cancer, ectropion or infection
Trauma
Atrophic vaginitis
Polyps
Endometrial cancer
Vaginal cancer
causes of pelvic pain
Urinary tract infection
Dysmenorrhoea (painful periods)
Irritable bowel syndrome (IBS)
Ovarian cysts
Endometriosis
Pelvic inflammatory disease (infection)
Ectopic pregnancy
Appendicitis
Mittelschmerz (cyclical pain during ovulation)
Pelvic adhesions
Ovarian torsion
Inflammatory bowel disease (IBD)
causes of vaginal discharge
Bacterial vaginosis
Candidiasis (thrush)
Chlamydia
Gonorrhoea
Trichomonas vaginalis
Foreign body
Cervical ectropion
Polyps
Malignancy
Pregnancy
Ovulation (cyclical)
Hormonal contraception
pruritis vulvae definition
itching of vulva and vagina
pruritus vulvae causes
Irritants such as soaps, detergents and barrier contraception
Atrophic vaginitis
Infections such as candidiasis (thrush) and pubic lice
Skin conditions such as eczema
Vulval malignancy
Pregnancy-related vaginal discharge
Urinary or faecal incontinence
Stress
primary amenorrhoea definition
defined as not starting menstruation:
By 13 years when there is no other evidence of pubertal development
By 15 years of age where there are other signs of puberty, such as breast bud development
puberty girls
8-14
breast bud, pubic hair, menstrual periods
pubertal growth spurt earlier than boys
hypogonadotropic hypogonadism
lack of LH and FSH
hypergonadotropic hypogonadism
lack of response to LH and FSH by gonads (testes and ovaries)
causes of hypogonadotropic hypogonadism
Hypopituitarism (under production of pituitary hormones)
Damage to the hypothalamus or pituitary, for example, by radiotherapy or surgery for cancer
Significant chronic conditions can temporarily delay puberty (e.g. cystic fibrosis or inflammatory bowel disease)
Excessive exercise or dieting can delay the onset of menstruation in girls
Constitutional delay in growth and development is a temporary delay in growth and puberty without underlying physical pathology
Endocrine disorders such as growth hormone deficiency, hypothyroidism, Cushing’s or hyperprolactinaemia
Kallman syndrome
causes of hypergonadotropic hypogonadism
Previous damage to the gonads (e.g. torsion, cancer or infections such as mumps)
Congenital absence of the ovaries
Turner’s syndrome (XO)
kallman syndrome clinical fx
delayed puberty
anosmia
CAH hormones
lack of cortisol and aldosterone
overproduction of androgens
CAH inheritance
aut rec
congenital deficiency of the 21-hydroxylase enzyme
clinical fx of CAH
neonates - hypoglycaemia, electrolyte disturbances
childhood - Tall for their age
Facial hair
Absent periods (primary amenorrhoea)
Deep voice
Early puberty
AIS in males patho
the tissues are unable to respond to androgen hormones (e.g. testosterone), so typical male sexual characteristics do not develop
AIS clinical fx
female phenotype - normal female external genitalia and breast
internally - undescended testis and absent uterus etc
if ovaries unaffected by pathology…
typical secondary sexual characteristics develop but no periods
