Amenorrhea Flashcards
DDX 2ndary Amenorrhea
Stress Weight loss Strenuous exercise Kallman’s syndrome Tumors Anovulation Ovarian failure/menopause Turner’s Syndrome or mosaicism Asherman’s
Anorexia Nervousa Def.
Anorexia nervosa-body image disturbance
and wt loss <85% of expected
Hyperprolactinemia symptoms
Galactorrhea Menstrual dysfunction Infertility Mass lesion Hirsutism Headache Visual Disturbances
Causes of Hyperprolactinemia
TRH Prolactinoma Idiopathic Other pituitary or brain tumor Pharmacology (Dopamine) Reglan, Aldomet, Opioids, antihystamines Renal Disease lactation pregnancy Stress/Exercise/Coitus etc.
Prolactin/Thryoid/GnRH
Elevated TSH results from elevated TRH TRH also causes prolactin release from pituitary PRL inhibits GnRH release, therefore anovulation occurs
Medical Risks of Turners
LEFT SIDED CARDIAC ANOMALIES OCCUR IN 50%
OF PATIENTS
RENAL ANOMALIES IN 1/3
HASHIMOTO’S THYROIDITIS IN ABOUT 50% (other autoimmune disorders)
Mild hearing loss
Insulin resistance
IF CONCEIVE, INCREASE IN BOTH TURNER AND
DOWN SYNDROME
Primary Ovarian Insufficiency
5-10% will conceive spontaneously
It is associated with Fragile X permutation
20% of adults will have hypothyroidism
Approximately 2% will have adrenal insufficiency
upon presentation and up to 2% more will
develop adrenal insufficiency. (This must be
detected prior to commencing transfer of oocyte
donor derived embryos)
Other autoimmune disease may co-exist
Fragile X
Gene FMR1
Number of repeats varies, if >200- affected, if
61-200 repeats -phenotypically normal but has
premutation
A female with premutation >90 is likely to have a
child with expanded repeats
Lab evaluation for 2ndary Amenorrhea
TSH
Prolactin
FSH
Progestin challenge- bleeding usually 2-7 days, sometimes 14 days (with ovulation)
FSH low and amenorrhea
Hypothalamic amenorrhea
Bromocriptine
Restores menstrual function in 80%
Reduces most tumors
Nausea and/or vomiting
Postural hypotension with syncope
Blurred vision
macroadenoma - 1 cm
Premature ovarian failure autoimmune screen
