On breast examination, a painless, firm, and rubber-like in texture nodule is found, what is it?
Fibroadenomas are the most common benign tumors of the breast.
What is Fibrocystic breast disease (FBD)?
Fibrocystic breast disease (FBD) is a disorder commonly seen in women of childbearing age that results in tender swollen breasts. FBD is most commonly seen with hormonal changes during a woman’s menstrual cycle and tends to improve towards the completion of their menstrual cycle. On examination, patient’s breasts are often tender to touch and can present with several small tender nodules throughout their breast tissue. These nodules are actually inflamed swollen breast lobules that results from a spike in estrogen levels during the menstrual cycle. This patient can most likely be observed for now given her current presentation and young age. If her breast lumps do not subside after a few weeks, she will likely require ultrasonography for further evaluation. Most FBD patients are treated with over-the-counter non-steroidals such as ibuprofen or naproxen, ice packs, or oral contraceptives.
What creates the blood-testis barrier?
Tight junction between Sertoli Cells.
What is Lichen simplex chronicus?
Lichen simplex chronicus is a chronic skin condition caused by a trigger, such as an irritant or infection, that causes pruritus, which leads to scratching. The scratching leads to skin damage which, in turn, leads to further itching. This itch-scratch cycle continues and leads to thickening of the skin. This patient has pruritus which began after exposure to a trigger (a new scented body wash) and has persisted, along with evidence of skin thickening on exam.
___________ is a chronic autoimmune condition that leads to thinning of the vulvar skin. Patients primarily complain of itching. Physical exam demonstrates “cigarette-paper” skin that is thin and wrinkled. The labia may be attenuated or obliterated, as may the clitoris. Skin changes often occur in an hourglass or figure-of-eight distribution.
Lichen sclerosus
Physical exam demonstrates “cigarette-paper” skin that is thin and wrinkled, what is the Disease?
Lichen sclerosus;
chronic autoimmune condition that leads to thinning of the vulvar skin.
a rare breast cancer characterized by scaly, vesicular, or ulcerated lesions that begin on the nipple and spread to the areola.
What is the patho?
Paget disease of the nipple/breast.
Other symptoms include bloody nipple discharge, nipple retraction, and sensations of pain, burning and/or pruritus. In 80 to 90% of Paget cases, there is an underlying breast cancer.
Pt. with Sx of enlarged, boggy uterus on exam is suggestive of what?
Adenomyosis
Adenomyosis occurs when islands of endometrial tissue grow within the uterine myometrium and is associated with dysmenorrhea (secondary dysmenorrhea), and menorrhagia.
Ectopic growth of endometrial tissue outside of the uterus is indicative of what?
Endometriosis
Bimanual exam of a patient with endometriosis might reveal adnexal masses (“chocolate cysts” on the ovaries), areas of tenderness, or nodularity of the uterosacral ligaments. The uterus would be expected to be a normal size and contour.
What would be the size and contour of the uterus in a pt. with endometriosis.?
The uterus would be expected to be a normal size and contour.
Dysregulated growth of smooth muscle within the myometrium describes what?
Uterine leiomyomas, or fibroids.
This describes uterine leiomyomas, or fibroids. Fibroids may also present with heavy and painful periods, but physical exam will reveal a “lumpy-bumpy” uterus with an irregular contour. The symmetrically enlarged, boggy uterus described here is more characteristic of adenomyosis.
A physical exam with a “lumpy-bumpy” uterus with an irregular contour ==??
Uterine leiomyomas, or fibroids.
The American College of Obstetricians and Gynecologists suggest against what type of exercise for a pregnant woman?
No hot-yoga. No off-road cycling.
patient should discontinue hot yoga and off-road cycling because these are considered unsafe during pregnancy due to heat stress and the risk of falling, respectively
Pregos can running all they want. This ligament contains the ovarian artery, vein, and nerves. The ovarian artery is the primary blood supply of the ovaries and forms anastomoses with the uterine artery.
What ligament of the uterus attaches the lateral aspect of the cervix to the abdominal wall?
cardinal (or transverse) ligament
What does the cardinal ligament contain?
uterine artery and uterine vein.
During hysterectomy, the cardinal ligament is often ligated to cut off blood flow to the uterus.
What is the difference between fibrocystic change and Fibroadenoma?
fibrocystic breasts sometimes present with breast tenderness that can usually be treated effectively with non-steroidal anti-inflammatory drugs. Increased breast pain or lumpiness often occurs just prior to a menstrual period.
Fibroadenoma is another benign condition; it is usually identified by a solitary lump, rather than bilateral changes.
During implantation, What structures secretes the hormones that keep the endometrium prepared for implantation of a developing embryo?
Corpus luteum;
synthesizes and secretes Progesterone. Progesterone increases vascularization and glandular secretion from the endometrial lining to help prepare the endometrium for receipt of a developing embryo.
No fertilization ==> decrease in progesterone and start of menses.
What is the regressed form of the corpus luteum that can no longer secrete hormones?
Corpus albicans
What is the regressed form of the corpus luteum that can no longer secrete hormones?
Corpus albicans
During the First Trimester:____ stimulates the production of progesterone by the corpus luteum.
hCG
hCG peaks during the first trimester.
What hormone stimulates peripheral insulin resistance in the mother during pregnancy.
Human placental lactogen stimulates peripheral insulin resistance in the mother. While this may benefit the infant by ensuring that adequate levels of glucose reach the placenta, it also contributes to gestational diabetes mellitus in the mother.
sildenafil is used to Tx erectile dysfunction, what is its MOA?
sildenafil exert their vasodilatory effects via inhibition of the enzyme phosphodiesterase (PDE5), which normally acts to break down cGMP in vascular smooth muscle. The smooth muscle cells produce cGMP in response to stimulation by nitric oxide, which in turn promotes smooth muscle relaxation.
What is a malformation of the venous plexus and is not a firm mass, that typically disappears when seated or lying down, secondary to improved venous drainage.
varicocele
What is a hydrocele?
hydrocele is a collection of peritoneal fluid that accumulates between the parietal and visceral layers of the tunica vaginalis and surround the testis and spermatic cord. The fluid in scrotal sac transilluminates distinguishing it from other scrotal masses includes hematocele,
