Q

8 functions of Oestrogen

A
  • Genital growth
  • Breast growth
  • Follicle growth
  • Endometrial growth
  • Upregulates OESTROGEN, LH and PROGESTERONE receptors
  • Inhibits FSH and LH through feedback mechanisms
  • Stimulates PROLACTIN secretion and LH surge (which causes ovulation)
  • Increases protein transport

Q

8 functions of Progesterone

A
  • Maintains progesterone
  • Produces cervical mucus
  • Increases BODY TEMPERATURE
  • Inhibits FSH and LH (like oestrogen does)
  • Downregulates OESTROGEN receptors
  • Increases ENDOMETRIAL GLAND secretion
  • Increases SPIRAL ARTERY DEVELOPMENT
  • Softens ligaments during pregnancy

Q

SIX steps of Menstrual Cycle

A

1- Increased oestrogen levels cause ENDOMETRIAL PROLIFERATION whilst GRAAFIAN FOLLICLE matures

2- Increased oestrogen levels cause an increased expression of GnRH receptors

3- Increased oestrogen also causes LH surge which causes OVULATION around day 14

4- Corpus luteum secretes PROGESTERONE which maintains ENDOMETRIAL LINING for implantation

5- If there is no implantation, the corpus luteum REGRESSES so PROGESTERONE LEVELS decrease

6- Progesterone levels no longer maintain the endometrium so the endometrium is shed

Q

4 Changes in Cardiovascular System during Pregnancy

A
  • Decreased BP- progesterone decreases vascular resistance by increasing SPIRAL ARTERY formation
  • Increased cardiac output
  • Increased blood VOLUME as BP stimulates RAAS

-MAY see Raynaud’s phenomenon due to peripheral circulation constriction

INCREASED-

  • Kidney size
  • GFR
  • UTI (due to dilated, elongated ureters)
  • Frequency of urination

Q

3 Changes in Dermatology during Pregnancy

A

Linea Nigra

Palmar erythema

Spider angioma

17
Q

Causes of Mastitis

A

Milk stasis or overproduction causes regional infection of BREAST PARENCHYMA with STAPHYLOCOCCUS AUREUS which enters the breast via trauma to the nipple

18
Q

Treatment of Mastitis

A

Encourage to continue breastfeeding

FLUCLOXACILLIN

19
Q

Where does Benign Prostatic Hyperplasia usually occur?

A

In the TRANSITIONAL ZONE of the prostate gland

20
Q

Causes of Benign Prostate Hyperplasia

A

Hypertrophy of EPITHELIAL and STROMAL cells of the Prostate gland

Thought to be driven by ANDROGEN DIHYDROTESTOSTERONE

21
Q

Signs and Symptoms of Benign Prostatic Hyperplasia

A

FUN BOO

Frequency
Urgency
Nocturia

Bladder Outflow Obstruction (BOO)

  • Hesitancy
  • Intermittent flow/ poor urine stream/ dribbling
  • Incomplete bladder emptying
22
Q

Investigations in Benign Prostate Hyperplasia

A

Enlarged but CMOOTH prostate gland with PALPABLE MIDLINE SULCUS

PSA will be raised

23
Q

Management of Benign Prostate Hyperplasia

A

Alpha 1 blockers (TAMSULOSIN)

5-alpha-reductase inhibitors (FINASTERIDE)

24
Q

Signs and Symptoms of Prostate Cancer

A

FUN BOO + others

Frequency
Urgency
Nocturia

Bladder Outflow Obstruction (BOO)

  • Hesitancy
  • Intermittent flow/ poor urine stream/ dribbling
  • Incomplete bladder emptying
  • Weight loss
  • Malaise and fatigue
  • Often spreads to bone, so BONE PAIN or PATHOLOGICAL FRACTURE
25
Q

Investigations in Prostatic Cancer

A

Midline sulcus is NO LONGER PALPABLE

Raised PSA

26
Q

Treatment of Prostatic Cancer

A

Radiotherapy

BRACHYTHERAPY

Goserelin (ZOLADEX)- Luteinising hormone releaseing hormon (LHRH AGONIST)

Antiandrogens- CYPROTERONE
