What are the classifications of amenorrhea?
Primary- normal secondary sexual characteristics and no period by the age of 16 OR no secondary sexual characteristics and no period by the age of 14
Secondary- no period in 3 months
What are several unique causes of amenorrhea?
Genetic abnormalities- androgen insensitivity syndrome, turner’s syndrome
Anatomic abnormalities- agenesis, vaginal septum
What are the major causes of amenorrhea?
PREGNANCY Hypothyroidism Hypothalamic-pituitary dysfunction Hyperprolactemia Premature ovarian failure
What goes into an evaluation for amenorrhea?
Physical examination- rule out anatomic abnormality
Karyotype- identify genetic abnormality
HCG- exclude pregnancy
TSH- exclude hypothyroidism
Prolactin- assess for pituitary microadenoma
FSH- assess for premature ovarian failure
Progesterone withdrawal- assess for hypoestrogen state
What is a progesterone withdrawal test?
Progesterone in oil (100mg) or medroxyprogesterone acetate (10mg daily x 5 days)
Withdrawal should occur withing 7-14 days
What do the results of a progesterone withdrawal test mean?
Withdrawal- Dx= hypothalamic-pituitary dysfunction. Treat with OCs or Clomiphene citrate, bromocriptine No withdrawal (low FSH)- Dx= hypothalamic pituitary failure, Treat with HRT or gonadotropins No withdrawal (high FSH)- Dx= premature ovarian failure, Treat with HRT or donor eggs
What are the classifications of dysmenorrhea?
Primary- due to excessive release of prostaglandin from a secretory endometrium
Secondary- due to an anatomic abnormality
What are possible causes of secondary dysmenorrhea?
Uterine myoma Uterine malformation Endometrial polyp Endometriosis IUD
What goes into the evaluation of dysmenorrhea?
Pelvic US or HSG- assess for myoma, polyp or malformation
Laparoscpoy- assess for endometiosis
What is the treatment for dysmenorrhea?
Medical: NSAIDS or Oral contraceptives
Surgical: Myomectomy, Polypectomy, Hysterectomy, Ablation of endometriosis
Definition of Menorrhagia
excessive menstrual blood loss
Definition of Menometrorrhagia
excessive blood loss during and between menses
What are the principal causes of abnormal uterine bleeding?
Anovulatory (dysfunctional) bleeding Endometrial hyperplasia or cancer Myoma Endometrial polyp Chronic endometritis Bleeding disorder (Von Willebrand's Disease o rThrombocytopenia) Thyroid Disease
What goes into an evaluation of abnormal uterine bleeding?
Platelet count- assess for thrombocytopenia
Platelet function assay- assess for platelet dysfunction
TSH- assess for thyroid disease
Hemoglobin/hematocrit- assess for anemia
What are the two tests of greatest value in assessment of a patient with abnormal uterine bleeding?
Pelvic US/hysterectomy- assess for myoma or endometrial polyp
Endometrial biopsy- assess for chronic inflammation, hyperplasia, cancer
