Christina Davis-Kankanamge Pediatric and Adolescent Gynecology Learning Objectives • Define abnormal uterine bleeding • Reasons for menstrual suppression • Options for menstrual suppression 1 Identification of abnormal menstrual patterns in adolescence may improve early identification of potential health concerns for adulthood. Abnormal Uterine Bleeding “outside of normal volume, duration, regularity, or frequency is considered abnormal uterine bleeding” excessive blood loss should be based on the patient’s perception Persistent anovulation is most frequent in the adolescent age group identification of abnormal menstrual patterns in adolescence may improve early identification of potential health concerns for adulthood 2 Menstrual Bleeding Normal Abnormal • Change of hygiene items every 1-2h • 3-6 hygiene items a day • Lasting more than 7d • Shorter interval than q21d or longer • Every 21-45d than 45d • <7d • Occur 90d apart even for one cycle • Are heavy and associated with excessive bruising/bleeding or a family history of bleeding d/o Menstrual Bleeding Normal Abnormal • 3-6 hygiene • Change of hygiene items every 1-2h items a day • Lasting more than 7d • Every 21-45d • Shorter interval than q21d or longer than 45d • <7d • Occur 90d apart even for one cycle • Are heavy and associated with excessive bruising/bleeding or a family history of bleeding d/o 3 … Or Not to Bleed Chimsom T. Oleka, MD, FACOG Pediatric and Adolescent Gynecology 4 ontact with the monthly flux of women turns new wine sour, makes crops wither, kills Cgrafts, dries seeds in gardens, causes the fruit of trees to fall off, dims the bright surface of mirrors, dulls the edge of steel and the gleam of ivory, kills bees, rusts iron and bronze, and causes a horrible smell to fill the air. Dogs who taste the blood become mad, and their bite becomes poisonous as in rabies. –Pliny the Elder, “Naturalis Historia: A Selection” 1st Century AD Attitudes Toward Menstruation • Men and younger adults report more negative attitudes • The worse the period is, the more negative the attitude • It has been argued that women believe menstruation to be a source of “social stigma” – Work hard to conceal the fact that they are menstruating – Shame and secrecy – Fear that the menstrual status will be discovered is perpetuated by menstrual product advertisements and education Brooks-Gunn & Ruble (1980).

Couts & Berg (1993)Kissling (1996) McKeever (1984) 5 • “Women, as members of a culture that sexualizes or objectifies their bodies, are motivated to distance themselves or dissociate from bodily functions, such as menstruation, that are deemed incompatible with their sexual attractiveness or desirability.” • The higher the level of self-objectification, the more likely the negative attitudes and emotions regarding menstruation. Roberts , T.A (2004) “Female trouble: The menstrual self-evaluation scale and women’s self-objectification” Psychology of Women Quarterly • Controversial • De-popularized monthly menses “While menstruation may be culturally significant, it is not medically meaningful.” 1999 6 Menstrual The use of contraceptive methods to eliminate Suppression or decrease the frequency of menses • Prescribed for adolescents to: – Treat menstrual disorders – Accommodate patient preference • There is no medical indication for menstruation to occur monthly 1/3rd of adolescents • Menstrual suppression is becoming who use COCs do so more common among contracepting for non-contraceptive adolescents reasons Kantartzis, K.L., Sucato, G.S. (2013) “Menstrual Suppression in the Adolescent”J Pediatr Adolesc Gynecol Conditions Treated with Menstrual Suppression • Patient preference • Malignancy • Menstrual-related problems • Hematologic abnormalities – Dysmenorrhea - Anemia – Pelvic pain - Thrombocytopenia – Heavy Menstrual Bleeding - Von Willebrand disease – Premenstrual syndrome – Endometriosis • Menstrual hygiene – Ovarian cysts – Developmental delay – Physical disabilities • Chronic conditions with cyclic exacerbations – Epilepsy – Migraines or other headaches – Asthma Kantartzis, K.L., Sucato, G.S.

(2013) “Menstrual Suppression in the Adolescent”J Pediatr Adolesc Gynecol Management of Irregular Bleeding: Unscheduled Hormone-free Intervals Continuous oral contraceptives: >7 consecutive days of unexpected bleeding = 3d hormone-free interval Continuous vaginal ring: >5 consecutive days of unexpected bleeding = 4d hormone-free interval Hormone-free intervals should not be used more frequently than every 3 weeks to ensure contraceptive efficacy Sulak PJ, et al. “Attitudes and prescribing preferences of health care professionals in the United States regarding use of extended-cycle oral contraceptives.” Contraception (2006) 10 Provider and Patient Concerns • Most gynecologist are comfortable prescribing menstrual suppression – 69% long-term use; 30% short-term use • Adolescent health care providers have been slower to adopt this practice • Extended regimens have no known impact on return to fertility – 86% pregnancy rate within 13 months of continuous cycle discontinuation • No data to suggest increased risk of cancer – DMPA use for 12 consecutive months in 5 years had 2-fold higher risk of developing breast cancer – Further research is needed Li Cl.
