Genomics

Genomic Medicine

Use of genome mixes in our healthcare system

Precision Medicine

Preventing and treating illness related to genes

ENCODE project

• Organized to identify the genome’s functional elements

• Function elements are proteins which interact with DNA to impact our genes

Presymptomatic testing

A gene mutation -> 100% chance of getting illness/disease with no symptoms yet

Predispositional Testing

A genetic mutation -> only predisposed to the illness/disease -> MAY OR MAY NOT get it (BRCA gene)

Gene therapy

An experimental technique that uses genes to treat or prevent disease

Cancer Genomics

• Environmental factors, acquired by change, inherited

• When cells reproduce more quickly your chance of cancer rises

• Oncogenes -> mutation in the gene

• Tumor suppressor genes -> genes are functioning

• Hereditary breast and ovarian cancer -> BRCA 1 or 2

  • Colorectal cancer -> APC tumor suppressor gene or mutations in two MMR genes

Amenorrhea

• Absence of menstrual flow (not a disease but a sign of one)

• Absence of menstruation after breast development

  • One of the most common gynecologic problems in women

Absence of menses by age 15, regardless of presence of normal growth and development

Secondary Amenorrhea

A 6-month or more absence of menses after a period of menstruation

Hypogonadotropic Amenorrhea

• Dysfunction of the central hypothalamic – pituitary axis

• Due to stress, weight loss, strenuous exercise, eating disorder, mental illness

  • Assessment: TSH and estrogen

Cyclic Perimenstrual Pain and Discomfort (CPPD) Primary

• (<25 years old)

• Condition associated with ovulatory cycles

• Excessive release of prostaglandins causes pain

  • Treatment: tens unit, yoga, Lamaze breathing (conscious breathing), exercise (endorphins can help with pain)

Cyclic Perimenstrual Pain and Discomfort (CPPD) Secondary

• 25 years

• Acquired menstrual pain that develops later in life

• Pelvic pathology – bloating and pelvic fullness

A lot of pain but also heavy bleeding

PMS Management

• Diet, exercise, herbal (fennel, ginger, chamomile)

Metrorrhagia

Between period bleedings (ovarian cysts, trauma, cyst, malignancy, polyps)

Hypermenorrhea

Excessive bleeding (neoplasm, infection, IUD)

Abnormal Uterine Bleeding (AUB)

Bleeding irregular in amount, timing, etc. (stops within 12-24 hours and is treated with estrogen)

Menopause

• Complete cessation of menses for >1 year

• Approx. 51.4 years old

• Premenopausal transition = 46 years

• 95% onset: 42-58 years

• Physiologic characteristics: frequent anovulation, cycles increase in length, ovarian follicles less sensitive to hormonal stimulation, progesterone is not produced by the corpus luteum, FSH values rise

• Physical: bleeding, vasomotor instability (hot flashes), mood and behavioral responses, insomnia,

• Estrogen stimulates egg release, maintains vaginal wall and lubrication, helps with lipid metabolism, and converts vitamin D to calcitonin for bone density

  • Progesterone helps with the lining of the endometrium

Health risks for perimenopausal women

Osteoporosis and coronary heart disease (because of changes in lipid metabolism)

FSH and LH should be equal levels (1:1)

• Both help growth and maturity

• Egg and sperm production

Methods of contraception

Coitus interruptus (“pulling out”) and Fertility Awareness Based Methods (FABs - which rely on avoidance)

How to calculate if a woman is fertile

For 6 months, note when period starts and ends

For the shortest period cycle subtract 11 days

For the longest period cycle subtract 18 days

Between those two calculated days

(Two days without secretions = not fertile)

Basal Body Temp

• Varies from 36.2-36.3 at wake during menses and approx. 5-7 days after (category of FABs)

  • If you don’t drop after menses, could be pregnant
