amboss 7/3 Flashcards
what is the treatment for PID
intramuscular ceftriaxone and oral doxycycline
what is the presentation of trichomonas vaginalis
anaerobic, motile protozoan with flagella. Patients typically have foul-smelling, frothy, yellow-green, purulent vaginal discharge with a pH > 4.5.
hows vaginalis transmitted
Transmission of this disease occurs through unprotected sex.
what is the presentation of gardnerella vaginalis
grey discharge, foul smelling, clue cells and a positive whiff test
what is the whiff test
The Whiff test consists of applying potassium hydroxide to a slide with vaginal discharge, and is positive if this causes a fishy or amine odor.
which strains of HPV genital warts, or condylomata acuminata.
HPV strains 6 and 11 cause 90% of genital warts, or condylomata acuminata.
what is the presentation of atrophic vaginitis or old pussy
Receding pubic hair and a decreasing labial fat pad are typical. dyspareunia and vaginal dryness are usual complaints
what is a risk factor for bacterial vaginosis
vaginal douching
is bacterial vaginosis an STD
no
what increases the risk of relapse for vaginosis
douching, intercourse
first-line treatment for vulvovaginal candidiasis in pregnancy
Intravaginal clotrimazole is a topical antifungal agent. Treatment primarily aims at the relief of symptoms, as candidal vulvovaginitis is not associated with adverse outcomes in pregnancy.
what are the screening recommendations for STDs in women
The USPSTF recommends screening for N. gonorrhoeae and C. trachomatis infections in sexually active women < 25 years old. If they are not diagnosed and treated, these infections may cause pelvic inflammatory disease and potentially infertility.
what is the next step in someone with a positive VDLR and clinical signs of secondary syphilis
confirmatory test, usually with fluorescent treponemal antibody
what is the treatment of choice for syhilis
intramuscular penicillin G
what is the treatment of choice for syphilis in pregnancy
penicillin
what do you do when someone is allergic to penicillin
give them a desensitization dose.
is allergen desensitization safe during pregnancy
yes
what is an alternative to syphilis treatment
doxycycline
what is the first line treatment for chlamydial infection
oral azithromycin
can you use azithromycin in pregnancy
yes
what is the most common cause of unilateral bloody nipple discharge
intraductal papilloma
The combination of a painful breast lump and erythematous overlying skin in a postmenopausal woman should be taken to indicate
a malignancy until proven otherwise!
what is a phyllodes tumor
A large (> 3 cm), rapidly growing (i.e., progression over days-weeks) breast mass raises suspicion for phyllodes tumor. biopsy shows a leaf-like appearance under the microscope
An elevated CA-125 is highly suspicious
for ovarian malignancy in a post-menopausal woman with an adnexal mass.
what is age for ultrasound vs mammogram
- younger is ultrasound, older is mammo
what is first line therapy for people with invasive ductal carcinoma
breast conserving therapy with sentinel node biopsy
what is the treatment for breast cancer in a pregnant woman
surgical resection poses little risk.
chemotherapy can be given after the first trimester
what should be done for patients with a simple breast cyst
if it is symptomatic, then needle aspiration can reduce the symptoms; if asymptomatic then leave alone and reassure
what are the findings for turners syndrome
webbed neck, widely spaced nipples, normal uterus, streak ovaries (gonadal dysgenesis, primary amenorrhea), coarctation of the aorta
what causes congenital edema in turners
Dysfunction of the lymphatic system is characteristic of Turner syndrome and typically leads to congenital lymphedema of the hands and feet starting in the neonatal period
what is the cause of normal breast development, normal vaginal and ovarian development but NO uterus
mullerian duct agenesis
Patients with androgen insensitivity syndrome present
with primary amenorrhea, a blind vaginal pouch, an absent uterus on ultrasonography, and normal breast development. However, patients would not have pubic hair, since the growth of pubic hair is dependent on androgens. Ultrasonography would reveal undescended testicles.
what is the presentation of 5-α reductase deficiency
results in reduced amounts of DHT. thus the genitalia form as masculine-feminine, there is no breast development, no uterus or ovaries. the person is genetically male, but has a vagina
when do girls undergo normal pubertal changes and what are they
between 8-11. they will begin to develop breasts, have pubic and axillary hair, and begin to have oily skin
what is the presentation of aromatase deficiency
Individuals with aromatase deficiency are unable to convert androgens to estrogens. Therefore, karyotypically female (46 XX) patients are born with ambiguous external genitalia and present with female pseudohermaphroditism. They have normal internal genitalia. At the time of puberty, they fail to develop secondary sexual characteristics and typically present with amenorrhea (due to the development of ovarian cysts that impair ovulation) as well as features of virilization due to increased testosterone (e.g., severe acne, hirsutism). Mothers of affected children may develop similar features during pregnancy due to fetal androgens crossing the placenta. In addition to these abnormalities of sex development, female as well as male individuals frequently have a tall stature due to a delayed fusion of the epiphyseal growth plates and signs of osteoporosis (e.g., bone fractures after minor trauma), caused by estrogen deficiency.
what can obesity cause
precocious puberty
what is the typical developmental course for females
thelarche, pubarche, menarche
tits, pits, mits, lips
what is the presentation of central precocious puberty
secondary sex charcterisitics, elevated bone age with a positive GnRH stimulations test.
what is the next step after diagnosis of central precocious puberty
MRI brain
what are the treatments fo choice for central precocious puberty
MRI brain, luprolide to suppress testosterone and estrogen then excision of the tumor
Recurrent midcycle, unilateral, lower abdominal pain in an adolescent girl is suggestive of
mittelschmerz.
what is the presentation of congenital adrenal hyperplasia
can also lead to peripheral precocious puberty as the excess adrenal androgens are aromatized to estrogen in the ovaries. However, due to a general excess in androgens, females are often born with ambiguous or male external genitalia, and virilization during puberty is common. This girl has normal external genitalia and no evidence of virilization (e.g., male-pattern hair growth).
what is precocious puberty without central findings
granulosa cell tumor
what are the two types of emergency contraception
include levonorgestrel or ulipristal acetate.
what is the most effective emergency contraception
copper-containing IUD.
what is the drawback of a copper IUD
typically only given when the woman does not want to get pregnant
what is the appopriate work up for primary amenorrhea
pregnancy test, ultrasound, FSH and LH
