Firecracker - Benign Gynaecology Flashcards
What five factors lead to endometrial proliferations by increasing estrogen levels?
- Patients with high levels of unopposed estrogen include:
- obese patients
- those using exogenous estrogen as medication
- patietns with estrogen secreting tumours (Granulosa theca cell tuours)
- patients with anovulatory cycles
- patients with PCOS
- Other risk facotrs include DM and HT possibly due to their association with obesity and PCOS.
What is adenomyosis?
- Defined as islands of endometrial glans within myometrium
- Patients present with severe menorrhagia and dysmenorrhea
- Generally in women older than 40
- Symmetrically enlarged ‘boggy’ uterus on bimanual examination, as compared to fibroid uterus which is ‘lumpy bumpy’
- Endometrial biopsy may be performed to rule out other causes of abnormal bleeding (i.e. endometrial hyperplasia) but the only way to diagnose adenomyosis definitively is with microscopic examination of the myometrium following hysterectomy
- Definitive treatment with hysterectomy which also gives definitive (pathologic diagnosis)
How is Lichen sclerosis treated?
- Lichen sclerosis is an atrophic skin condition found on the vulva of the post-menopausal women
- The condition causes:
- skin thinning
- pruritis
- contracture of the vaginal introitus
- therefore painful sex
- Has an association with increased risk of vulvar cancer
- Treatment:
- Topical corticosteroid cream such as Clobetasol
How is primary dysmenorrhea diagnosed?
- PD is idiopathic - it is menstrual pain in the absence of any hormonal or anatomic pathology
- Usually presents before the age of 20 and will often decrease throughout a patient’s 20s and early 30s
- Symptoms include:
- Nausea
- Vomiting
- Headache
- The diagnosis is made based on history and the absence of an organic cause
Note that the pain from primary dysmenorrhea usually begins on the first or second day of the menstrual cycle whereas pain from endometriosis usually occurs 1-2 weeks before menstruation.
What are some multiorgan system effects associated with toxic shock syndrome?
- Acute onset of high fevers greater than 102F
- Vomiting and diarrhea
- Sore throat
- Generalized macular rash
Patients in more severe cases can develop:
- hypotension secondary to shock
- respiratory distress
- desquamation of the palms and soles
The generalised rash associated with TSS is a diffuse erythema that starts on the trunk and spreads to the extremities which leads to erythemaof palms and soles. It resembles sunburn
Multiorgan system involvement is also associated with toxic shock syndrome and can include:
- GI symptoms including profuse diarrhea
- Pre-renal and intrinsic renal failure
- Hyponatremia, hypocalcemia and hypophosphatemia secondary to the renal failure
- Diffuse myalgia with elevated creatinine phosphokinase
- Confusion due to cerebral edema
What is dysmenorrhea?
Pain and cramping during menstruation that interferes with normal activities and requires medication - it can be primary or secondary
How does endometrial hyperplasia present?
- Presentation
- Usually a patient experiences a long period of oligomenorrhea or amenorrhea followed by return of menses.
- Recognizing this pattern is key to diagnosis and treatment
- Usually a patient experiences a long period of oligomenorrhea or amenorrhea followed by return of menses.
- Diagnosis
- Made via an endometrial biopsy
- Treatment
- Most hyperplasia can be treated with progesterone which causes decidualization of the endoemetrium
- Forms of progesterone include Depo-Provera, the Mirena IUD, oral progesterone or topical progesterone
- A repeat endometrial biopsy is performed after 3 months of treatment
Atypical complex hyperplasia is the most severe form of hyperplasia and is a precursor to endometrial carcinoma in one third of untreated patients.
Therefore a hysterectomy should be performed in these patients
What is the first choice of treatment in the management of fibroids?
- Management of asymptomatic uterine fibroids involves monitoring the patient with ultrasound to detect abnormal growth
- Pharmacological treatment options are often the first choice in management of symptomatic uterine fibroids
- For patients with moderate pain associated with uterine fibroids:
- NSAIDs and expectant management
- For patients with heavy bleeding associated with uterine fibroids, OCPs, medroxyprogesterone acetate, progestin implants or danazol may be used
- GnRH agnonists are used to decrease the size of the fibroids as well as decrease the vascularity
- Recall a GnRH agonist such as Leuprolide acts as an antagonist when used in continuous fashion (decreased FSH and LH lead to decreased circulating estrogen)
Briefly, what are the surgical options for treating fibroids?
- Surgical management is appropriate for patients who suffer severe symptoms, such as anemia from menorrhagia, or in patients who have become infertile due to fibroids and wish to maintain fertility.
- Endometrium overlying fibroids is less well-perfused than endometrium overlying normal myometrium, and is unable to support a pregnancy.
- Myomectomy is the removal of one or more fibroids laproscopically, hysteroscopically, or abdominally. This procedure can improve fertility in patients with subendometrial fibroids.
- Hysterectomy is used to treat severe symptoms in patients with no desire to maintain fertility.
- Uterine artery embolization is another treatment available for patients with uterine fibroids, which involves selectively infarcting small fibroids. Note: uterine artery embolization carries a high likelihood of impaired fertility.
What are the risk factors for the development of uterine fibroids?
Risk factors for uterine fibroid development include:
Nulliparity
African American heritage
Diet high in meat
Alcohol consumption
Family history
What are fibroids?
- Fibroids or uterine leiomyomas or are benign growths of smooth muscle that are commonly found in the myometrium (smooth muscle layer deep to the endometrium) in reproductive age women
- They are classified:
- Submucosal - just deep to the endoemtrium, affects the interior shape of the uterine cavity and cause heavy menses
- Intramural - in the muscular wall of the uterus which is the most common type
- Subserosal - just deep to the serosa on the exterior of the uterus. These can impinge on the uterus and other pelvic structures
Their growth is stimulated by estrogen and progesterone - as a result symptoms vary with the menstrual cycle, worsen rapidly during pregnancy and improve following menopause.
Symptoms of endometriosis?
- Women in their 20s or 30s with endometriosis may present with infertility and three Ds
- Dysmenorrhea (painful menses)
- Dyspareunia (painful sexual intercourse)
- Dyschezia (painful defecation)
- In addition to the three Ds, endometriosis may present with:
- Pelvic pain
- Possible infertility
- Uterine or adnexal tenderness
- Palpable adhesions on uterus or ovaries
- The most common site of endometriosis include:
- Adnexa - ovaries being the most common
- Rectouterine pouch of Douglas
- Bowel, bladder and peritoneum
What is hypomenorrhea?
Hypomenorrhea is regularly timed menses with light bleeding.
Common causes of hypomenorrhea include:
Hypogonadism (seen in anorexia, heavy exercising)
Contraception use
Asherman’s syndrome (intrauterine adhesions)
What is a Bartholin’s cyst?
- A bartholin’s cyst occurs when outflow from the glands of Bartholin is obstructed.
- Recall, the Bartholin ducts are mucus-secreting ducts that are located at 4 and 8’o’clock on the vaginal orifice
- Small cysts can be treated witih Sitz baths whereas large, painful cysts should be incised and drained
- To prevent reformation of a large abscess, a drain, such as Word Catheter, should be left in place after drainage
- Antibiotic coverage of Neisseria gonorrhea and skin flora such as Staph.aureus should be administered
What is secondary dysmenorrhea?
Secondary dysmenorrhea is menstrual pain due to an underlying pathology, such as:
- Endometriosis
- Fibroids
- Adenomyosis
- PID
- Cervical stenosis
How is the pain from primary dysmenorrhea differ from that of endometriosis?
- Primary dysmenorrhea is idiopathic menstrual pain that has no identifiable pathology
- Primary dysmenorrhea usually presents before the age of 20 and will often decrease throughout a patient’s 20s and early 30s
- Symptoms include nausea, vomiting and headache
- The diagnosis is made based on history and absence of an organic cause
- Note that pain from primary dysmenorrhea usually begins on the first or seconday day of the menstrual cycle whereas pain from endometriosis usually occurs 1-2 weeks before menstruation.
What are the clinical criteria required to make a diagnosis of toxic shock syndrome?
- The diagnosis of toxic shock syndrome is based on the clinical presentation, which must include:
- Presence of high fevers greater than 38.9
- Hypotension
- Erythroderma and desquamation
- Involvement of 3 organ systems
- Labs will show:
- S.aureus in vaginal fluid cultures associated with tampon use
- Thrombocytopenia
- Increased ALT and AST
- Increased BUN and creatinine

What symptoms indicate a more severe case of toxic shock syndrome?
- Hypotension
- Respiratory distress
- Desquamation of palms and soles
What symptoms are associated with uterine fibroids?
- Half of women with fibroids are asymptomatic. Those with symptoms may present with the following:
- Abnormal uterine bleeding (menorrhagia, metrorrhagia) especially with submucosal fibroids
- Pelvic pain from subserosal fibroids
- Infarction (due to outgrowth of blood supply), resulting in degeneration, necrosis and pain
- Impingement of pelvic structure, resulting in constipation, venous stasis, hydronephrosis and urinary retention
- Infertility
What are the most common sites of endoemetriosis?
- The most common site of endometriosis include:
- Adnexa - ovaries being the most common
- Rectouterine pouch of Douglas
- Bowel, bladder and pertioneum
What symptoms are associated with premenstrual syndrome and premenstrual dysphoric disorder?
- Symptoms of premenstrual syndrome and premenstrual dysphoric disorder include:
- Food cravings, weight gain
- Headache
- Abdominal or pelvic pain, abdominal bloating, change in bowel habits
- Mood lability, depression, fatigue and irritability
- Breast tenderness
- Acne
- 5-10% of women have severe symptoms that interfere with daily life
- Symptoms associated with PMS and PMDD precede menses and occur at similar poitns in each cycle
- If a patient suspected of having PMS or PMDD has mood symptoms throughout her entire menstrual cycle (rather than only the second half) , a psychiatric workup for the mood disorder should be initiated.
What is menorrhagia?
Menorrhagia is normally timed menstrual cycles but with excessive bleeding.
Common causes of menorrhagia include:
uterine fibroids
adenomyosis
endometrial polups
(less commonly) endometrial hyperplasia and cancer
If a teenager suffers from menorrhagia, it is recommended that she can be checked for a bleeding disorder (ITP, vWD)
What is metrorrhagia?
- Metrorrhagia is when a patient has regular cycles, but experiences bleeding between those cycles
- Causes of metrorrhagia include:
- Cervical lesions
- Endometrial polyps
- Endometrial carcinoma
