Answer 2

Clinical features & staging return back to endometrial cancer

Indication of radiotherapy

1. when hysterectomy is medically contraindicated. primary radiotherapy can offer 5-years disease specific survival rate of 80-90%.

2.adjuvant radiotherapy after surgery :whole pelvic radiotherapy( external beam radiotherapy EBR ) & intravaginal brachytherapy are potential adjuvant postoperative therapy for stage 1 disease. The use of intravaginal brachytherapy in stage IB grade 1 &2 significantly reduce the incidence of vaginal recurrence to less than 1%.

3.for stage II endometrial carcinoma , pre & postoperative radiotherapy may be administered.

4. For stage III-IV, there may be combination of pelvic EBR, whole abdominal radiotherapy, intravaginal brachytherapy & chemotherapy. The total dose of 45 Gy is typically given in 25 fractions administered 5 days\week.

The intravaginal brachytherapy the dose is 5 G \week & the total 15 Gy to depth of 0.5 cm given over the upper 3-4 cm given in 3 weeks. Carcinoma of the cervix:

Clinical feature, staging & treatment : return back to ca-cervix

Indication of radiotherapy:

Patient who undergo radical hysterectomy with histopathological

1.evidance of tumor spread to regional lymph node

2. tumor at the surgical margin
3. microscopical involvement of paramaterium

All are indication for radiotherapy or chemoradiation.

Chemo- radiation can be used as adjuvant therapy in respectable tumor, or primary therapy in advanced disease. Regimn:

EBR used to the primary tumor+ lymph node at a dose of 40-45 Gy to the pelvis in fraction of 1.8-2 Gy Cisplatin is usually given weekly at dose of 40mg\m2 of body surface area with a maximum weekly dose of 70 mg. Complication of chemoradiation:

& need 1. anemia For blood transfusion to maintain Hb between 10-12 g \dl.

2. electrolyte disturbance: hypokalemia , hypomagnesaemia& hypocalcaemia.
3. radiation exposure of the bowel, bladder lead to diarrhea, cystitis, small bowel obstruction, fibrosis , proctitis, sigmoid stricture , ureteral stricture& chronic hemorrhagic cystitis.

Brachytherapy involve the temporary placement of intrauterine tandem & intravaginal ovoid that are loaded with radioactive material , the device is applied under general anesthesia or strong sedation. Ovarian cancer & ovarian hormonal ablation:

Clin. Feature& staging: return back to ovarian tumor.

Palliative radiotherapy is frequently offered to patient who have focally symptomatic recurrence of ovarian cancer.

Radiotherapy can also be applied when ovarian hormonal ablation is indicated. Most commonly in the treatment of estrogen- receptor positive breast cancer in pre-menopausal women. Vulvar & vaginal cancer:

Question 4

Adverse effects of hysterectomy

Answer 4

The average onset age of menopause after hysterectomy with ovarian conservation is 3.7 years earlier than average. This has been suggested to be due to the disruption of blood supply to the ovaries after a hysterectomy or due to missing endocrine feedback of the uterus. The function of the remaining ovaries is significantly affected in about 40% of women, some of them even require hormone replacement treatment.

Question 5

Hysterectomy
Urinary incontinence & vaginal prolapse
Adhesion formation and bowel obstruction
Wound infection

Answer 5

Urinary incontinence and vaginal prolapse Urinary incontinence and vaginal prolapse are well known adverse effects that develop with high frequency a very long time after the surgery. Typically, those complications develop 10–20 years after the surgery Adhesion formation and bowel obstruction The formation of postoperative adhesions is a particular risk after hysterectomy because of the extent of dissection involved as well as the fact the hysterectomy wound is in the most gravity-dependent part of the pelvis into which a loop of bowel may easily fall.In one review, incidence of small bowel obstruction due to intestinal adhesion was found to be 15.6% in non-laparoscopic total abdominal hysterectomies vs. 0.0% in laparopscopic hysterecomies.

Wound infection occurs in approximately 3% of cases of abdominal hysterectomy. Such wound infections mainly take the form of either incisional abscess or wound cellulitis. Removal of the uterus without removing the ovaries can produce a situation that on rare occasions can result in ectopic pregnancy due to an undetected fertilization that had yet to descend into the uterus before surgery. Ureteral injury is not uncommon and occurs in 0.2 per 1,000 cases of vaginal hysterectomy and 1.3 per 1,000 cases of abdominal hysterectomy.The injury usually occurs in the distal ureter close to the infundibulopelvic ligament or as a ureter crosses below the uterine artery, often from blind clamping and ligature placement to control hemorrhage.

Question 6

Abdominal hysterectomy
Vh
Lh
Lavh

Answer 6

Most hysterectomies in the United States are done via laparotomy (abdominal incision, not to be confused with laparoscopy). A transverse (Pfannenstiel) incision is made through the abdominal wall, usually above the pubic bone, as close to the upper hair line of the individual’s lower pelvis as possible, similar to the incision made for a caesarean section. This technique allows physicians the greatest access to the reproductive structures and is normally done for removal of the entire reproductive complex. The recovery time for an open hysterectomy is 4–6 weeks and sometimes longer due to the need to cut through the abdominal wall.

Vaginal hysterectomy Vaginal hysterectomy is performed entirely through the vaginal canal and has clear advantages over abdominal surgery such as fewer complications, shorter hospital stays and shorter healing time. Abdominal hysterectomy, the most common method, is used in cases such as after caesarean delivery, when the indication is cancer, when complications are expected, or surgical exploration is required. Laparoscopic-assisted vaginal hysterectomy With the development of laparoscopic techniques in the 1970s and 1980s, the “laparoscopic-assisted vaginal hysterectomy” (LAVH) has gained great popularity among gynecologists because compared with the abdominal procedure it is less invasive and the post-operative recovery is much faster. It also allows better exploration and slightly more complicated surgeries than the vaginal procedure. LAVH begins with laparoscopy and is completed such that the final removal of the uterus (with or without removing the ovaries) is via the vaginal canal. Thus, LAVH is also a total hysterectomy; the cervix must be removed with the uterus. Laparoscopic-assisted supracervical hysterectomy The “laparoscopic-assisted supracervical hysterectomy” (LASH) was later developed to remove the uterus without removing the cervix using a morcellator which cuts the uterus into small pieces that can be removed from the abdominal cavity via the laparoscopic ports.

Total laparoscopic hysterectomy.

RECOVERY Hospital stay is 3 to 5 days or more for the abdominal procedure and between 1 and 2 days (but possibly longer) for vaginal or laparoscopically assisted vaginal procedures.[

Answer 8

• stage II-IV & stage Ic.

• given as primary treatment, as an adjunct following surgery or for relapse of disease.

• given to prolong clinical remission & survival, & for palliation in advanced & recurrent disease.

• 3 weeks apart for six cycles.

• The platinum drugs, cisplatin & its analogue carboplatin are heavy metal compounds which cause cross-linkage of DNA strands. • Carboplatin is the drug of choice, as effective as cisplatin with lesser side effects.

• Paclitaxel works by causing microtubular damage to the cell thus prevents replication and cell division.

• Bevacizumab, a monoclonal antibody against vascular endothelial growth factor (VEGF), inhibits angiogenesis, clinically effective at improving recurrence free and overall survival when given in combination with carboplatin and paclitaxel in advanced ovarian cancer

• Follow-up of patients includes clinical examination and CA125 measurement Prognosis: The overall 5-year survival from ovarian cancer is 46%

Functional cyst

Answer 9

Functional cyst: The risk of developing these

cysts is reduced by the use of the combined oral contraceptive pill.

Follicular cyst: may persist for several

menstrual cycles & rarely achieve a diameter of up to 10 cm. may produce estrogen causing menstrual disturbance & endometrial hyperplasia

Luteal cyst: Corpora lutea are not called luteal

cyst unless they are more than 3 cm, usually presented with pain due to rupture or haemorrhage.

Question 10

Histological Classification of benign ovarian tumours

Answer 10

I- Benign germ cell tumours:

– Dermoid cyst (mature cystic teratoma)

– Mature solid teratoma

II- Benign epithelial tumours:

– Serous cystadenoma

– Mucinous cystadenoma

– Endometrioid cystadenoma

– Brenner tumours III- Benign sex cord stromal tumours:

– Theca cell tumours

– Fibroma

Question 11

Benign germ cell tumours:

Answer 11

Benign germ cell tumours:

• The commonest ovarian tumours seen in women less than 30 years old.

• arise from totipotential germ cells & may contain elements of all three germ layers (embryonic differentiation). Dermoid cyst (mature cystic teratoma):

• usually unilocular

• < 15 cm in diameter

• ectodermal structures are predominant. lined with epithelium like the epidermis & contains skin appendages, teeth, sebaceous material, hair & nervous tissue.

• Endodermal derivatives include thyroid, bronchus & intestine,

• the mesoderm may be represented by bone, cartilage & smooth muscle Mature cystic teratoma •

•

•

monodermal teratoma: The classic example is struma ovarii which contains hormonally active thyroid tissue.

majority are asymptomatic. may undergo torsion or rupture spontaneously, either suddenly, causing an acute abdomen & chemical peritonitis; or slowly causing chronic granulomatous peritonitis.

< 2% contain malignant component

Question 12

Benign Epithelial tumours:

Answer 12

Benign Epithelial tumours: Serous cystadenoma

•

•

•

The most common benign epithelial tumour

usually unilocular cyst with papilliferous processes on the inner surface.

The cyst fluid is thin & serous. They are seldom as large as mucinous tumours. Mucinous cystadenoma

• Large

• Unilateral

• multilocular cysts

• smooth inner surface.

• lining epithelium consists of columnar

mucus-secreting cells.

• The cyst fluid is thick & gelatinous.

• Complication: pseudomyxoma peritonei

Question 13

Benign sex cord stromal tumours:

Answer 13

Benign sex cord stromal tumours:

• Constitute a small percentage of benign ovarian tumours.

• They occur at any age

• Theca cell tumour secrete hormones & present with symptoms of inappropriate hormone effects Fibroma:

•

•

Solid, composed of stromal cells, present in older women.

Meig’s syndrome: ascites & pleural effusion in association with fibroma of the ovary, seen in only 1% of cases.

Question 14

Differential diagnosis of benign ovarian tumours

Answer 14

Pain

• Ectopic pregnancy

• Spontaneous abortion

• Pelvic inflammatory diseae

• Appendicitis

• Meckel’s diverticulum

• Diverticulitis Abdominal swelling

• Pregnant uterus

• Fibroid

• Full bladder

• Ovarian malignancy

• Colorectal carcinoma Pressure effects

• Urinary tract infection

All other causes of menstrual irregularities, precocious puberty & postmenopausal bleeding.

Question 15

BOC
Ix

Answer 15

Ultrasound: TVUS may need abdominal US, mass size, consistency, and internal architecture. Bilatrality, ascites

Doppler ultrasonographies to evaluate the resistive index of the mass vessels, which, when low, may indicate a malignancy.

if in doubt

MRI Blood test & serum markers: some times needed:

1. serum CA 125
2. beta-human chorionic gonadotrophin (βhCG)
3. Oestradiol
4. Androgen
5. alpha-fetoprotein levels
6. Lactate dehydrogenase (LDH) • A serum CA-125 assay does not need to be undertaken in all premenopausal women when an ultrasonographic diagnosis of a simple ovarian cyst has been made.

• Lactate dehydrogenase (LDH), α-FP and hCG should be measured in all women under age 40 with a complex ovarian mass because of the possibility of germ cell tumours.

Question 16

In Perimenopausal Women: What is the best way to estimate the risk of malignancy?

Answer 16

Risk of Malignancy Index: The RMI is a product of the ultrasound scan score, the menopausal status and the serum CA-125 level (IU/ml) as follows:

RMI = U x M x CA-125.

If ≥200 high suspicion of malignancy

Question 17

Criteria for observation of asymptomatic ovarian cyst:

Answer 17

• Unilateral

• Unilocular cyst without solid components

• Premenopausal women tumour 3-7 cm in diameter

• Normal CA 125 ( <35mIU/mL)

• No free fluid or masses suggesting omental cake or matted bowel loops. •

•

•

•

Women with small (less than 50 mm diameter) simple ovarian cysts generally do not require follow-up as these cysts are very likely to be physiological and resolve within 3 menstrual cycles.

Women with simple ovarian cysts of 50–70 mm in diameter should have yearly ultrasound follow-up

those with larger simple cysts should be considered for either further imaging (MRI) or surgical intervention.

Ovarian cysts that persist or increase in size are unlikely to be functional and may warrant surgical management.

3- SERM , Tibolone. 4-Antiprogesterone.

PRM (Asoprisnil).

5- Ulipristal. ’ Relugolix :

is a small molecule that binds to the gonadotrophin-releasing hormone receptor in the pituitary gland, decreasing production of oestrogen and progesterone by the ovaries.

’ It is administered orally, in combination with oestradiol and norethindrone acetate. Treatment for control heavy periods may include:

’ combined pills:

’ Intrauterine system (Marina):

That release hormone to reduce heavy bleeding and pain ’ Iron supplements:

to treat anaemia .

’ NSAID : ibuprofen or naproxen mefenamic acid for pain.

’ Hormone therapy help shrink fibroids only for a short time. C- Surgical treatment: ’ Myomectomy:

is the surgical removal of fibroids . The approaches:

’ Abdominal myomectomy:

removes fibroids through an incision in the abdomen. ’ Laparoscopic or Robotic Laparoscopic myomectomy :

uses several small incisions in the abdomen to remove fibroids.

’ Hysteroscopic Myomectomy:

by resectoscope for less than 3 cm fibroid. ’ Vaginal Myomectomy:

removal of the fibroid through the vagina.

Advantage of myomectomy: ’ Preserve fertility.

Disadvantage: ’ recurrence. ’ Hysterectomy:

removal of the uterus &Fibroids. ’ Abdominal hysterectomy:

’ Vaginal hysterectomy:

’ Laparoscopic hysterectomy: ’ Robotic Hysterectomy: Similar to a

laparoscopic hysterectomy except that the instruments are connected to robotic arms, allowing the surgeon to have enhanced dexterity and visualization.

’ Advantages of hystrectomy:

less blood loss ,cure ,no recurrence. D- Minimally invasive procedures: Certain procedures can destroy uterine fibroids without actually removing them through surgery. They include:

’ Uterine artery embolization.

’ Small particles (embolic agents) are injected into the arteries supplying the uterus, cutting off blood flow to fibroids, causing them to shrink and die. ’ Advantages of UAE:

’ decrease menstrual loss by 85%.

’ Decrease myoma size by 30- 46%. ’ Short hospital stay.

’ Disadvantages: pain, nausea ,fever , vaginal discharge , ovarian dysfunction and elevated FSH. ’ Radiofrequency ablation.

’ In this procedure, radiofrequency energy destroys uterine fibroids and shrinks the blood vessels that feed them. This can be done during a laparoscopic or transcervical procedure or under U/S guidance .

’ A similar procedure called cryomyolysis freezes the fibroids. ’ Focused Ultrasound Therapy:

’ MR-guided, focused ultrasound

obliterates tumours by focusing highintensity ultrasound beams on the growths, raising the temperature enough to destroy them. Focused u/s Therapy ’ By the MR scanner the Interventional Radiologist localise the fibroid, a small spot is treated at a time and it is repeated, about 50 times per session, until the fibroid is destroyed.

’ It’s uses for symptomatic women, complete family who have few fibroids.

’ Large and multiple small fibroids are difficult to treat.

Answer 31

Urinary Fistula:( True Incontinence)

Constant feeling of wetness without sensation of urine leakage.

Vesico -vaginal F.

Uretero -vaginal fistulas are the most feared complications of female pelvic surgery. More than 50% of such fistulas occur after hystrectomy for benign diseases as uterine fibroids, menstrual abnormalities, and uterine prolapse.

The incidence of vesico-vaginal fistula is unknown. The incidence of vesico-vaginal F. resulting from hysterectomy is estimated to be less than 1%.  In USA, more than 50% of vesicovaginal and

ureterovaginal F. occur after hysterectomy for benign diseases.

 Pelvic radiation is the primary cause of

delayed fistula. Radiation is used to treat cervical or endometrial carcinoma .

 In developing countries, obstetrical complications are the most common cause .  In cases of longstanding and obstructed labour leading to pressure necrosis on the anterior vaginal wall. It may be large and have extensive local tissue damage and necrosis. Diagnosis:

 Vesico-vaginal and Uretero-vaginal fistulas recognized within 3-7 days after the causative operation may be repaired immediately via a trans-abdominal or trans-vaginal approach.

 Fistulas identified after 7-10 days

postoperatively should be monitored periodically until all signs of inflammation and indurations have resolved.  The traditional approach has been to wait at least 3-4 months before fistula closure.

 Some they close the fistula with or without using peritoneal flap without waiting 3-4 months.

 Patients with a history of multiple failed

repairs, patients with associated enteric fistula or patients with a history of pelvic radiation should not undergo fistula repair for at least 6-8 months. For a small fistula, an initial trial of urethral catheter drainage may be attempted for 4-6 weeks. Optimal success achieved in patients who had longer and narrower fistulas.

. Persistent incontinence after an adequate period of watchful waiting requires open exploration and formal fistula repair.  The trans-vaginal approach is the safest and most comfortable for the patient.

 A history of previous failed repairs does not preclude trans-vaginal reconstruction.

 Fistulas occurring after hysterectomy are usually amenable to trans-vaginal reconstruction.

 Trans-vaginal repairs do not require excision of the fistula tract.

No treatment is necessary if incidental asymptomatic mild prolapse is found. There is no evidence about how to treat these women. ’ Conservative treatment options:

 Lifestyle modification:

 • losing weight, if the woman has a BMI greater than 30 kg/m2  • minimizing heavy lifting  • preventing or treating constipation. treatment of cough, smoking cessation Pelvic floor muscle exercises:

’ When the pelvic floor muscles work well, they hold the bladder, bowel, and vagina in the right position, and pelvic floor exercises can help women with mild to moderate prolapse

’ There is no definite evidence for the benefit of pelvic floor muscle exercises in the management of uterine prolapse  . It may be beneficial as primary therapy for early stages of uterine prolapse.

 Vaginal oestrogen creams:

some advocate a trial of topical oestrogen cream for 4-6 weeks if prolapse is mild but there is no current evidence of any benefit. Consider vaginal oestrogen for women with pelvic organ prolapse and signs of vaginal atrophy. ’ Vaginal pessary insertion:

A good alternative to surgery.

’ Inserted into the vagina to reduce the prolapse, provide support and relieve pressure on the bladder and bowel.

’ Made of silicone or plastic. Pessaries are effective:

 For short-term relief of prolapse prior to surgery.

 In the long term if surgery is not wanted or is contra-indicated. ’ Fitting a pessary:

 Ensure the patient’s bladder and bowel are empty

 Perform a bimanual examination and estimate the size of the vagina.

Question 38

Cervical insufficiency (cervical incompetence)

Answer 38

Cervical insufficiency (cervical incompetence) is defined as the inability of the uterine cervix to retain a pregnancy in the second trimester, in the absence of uterine contractions. the following indications for cervical cerculage:

History of second trimester pregnancy loss with painless cervical dilatation

Prior cerculage placement for cervical insufficiency

History of spontaneous preterm birth (prior to 34 weeks’ gestation) and a short cervical length (ie, < 25 mm) prior to 24 weeks’ gestation

Painless cervical dilatation on physical examination in the second trimester

Signs and symptoms

The diagnosis of cervical insufficiency is primarily based on a history of

a previous midtrimester pregnancy loss, which can present with the

following:

Painless cervical dilatation and bulging fetal membranes upon presentation in the second trimester of pregnancy

Preterm premature rupture of membranes (PPROM)

Rare or absent uterine contractions

In women without a history of pregnancy loss, the diagnosis of cervical insufficiency is based on a combination of the following:

Clinical presentation, Physical examination &Ultrasonographic findings Most patients are asymptomatic, but some may present with any the following symptoms: Pelvic pressure , Cramping , Back pain , Increased vaginal discharge

Diagnosis

Although the diagnosis of cervical insufficiency may be based on a history of midtrimester pregnancy loss, the following measures may also be useful:

Ultrasonographic transvaginal measurement of cervical length – Cervical length has a strong inverse correlation with the risk of spontaneous preterm birth, particularly in women with a history of preterm delivery

Fetal fibronectin (fFN) testing – Studies have demonstrated the utility of fFN testing in addition to cervical length assessment, with a significant improvement in the prediction of preterm delivery in women with a positive fFN and a cervical length of less than 25 mm

Management

The mainstay of surgical treatment for cervical insufficiency is cervical cerclage, which is reasonable in the following situations:

1-History of second trimester pregnancy loss with painless cervical dilatation

2-Prior cerclage placement for cervical insufficiency

3-History of spontaneous preterm birth (prior to 34 weeks’ gestation) and a short cervical length (ie, < 25 mm) prior to 24 weeks’ gestation

4-Painless cervical dilatation on physical examination in the second trimester

Cerclage can be accomplished either TV or transabdominally. Cerclage is usually done TV as either a McDonald or Shiradkor procedure. When these 2 procedures are unsuccessful or difficult to perform, the transabdominal cerclage procedure is done . RH status:-AntiD is required in the following circumferences for nonsensitized Rh negative women .

1-Spontaneous miscarriage 12 wk & more .

2-At any GA with surgical or medical intervention 3-At any GA with repeated severe bleeding .

Question 39

Ectopic pregnancy
Risk factors

Answer 39

Risk factors

Multiple factors contribute to the relative risk of ectopic pregnancy. In theory, anything that hampers or delays the migration of the fertilized ovum (blastocyst) to the endometrial cavity can predispose a woman to ectopic gestation. The following risk factors have been linked to ectopic pregnancy:

1- Pelvic inflammatory disease

A history of major tubal infection decreases fertility and increases abnormal implantation. The most common cause of PID is an antecedent infection caused by Chlamydia trachomatis. Patients with chlamydial infection have a range of clinical presentations, from asymptomatic cervicitis to salpingitis and florid PID. More than 50% of women who have been infected are unaware of the exposure.

Other organisms that cause PID, such as Neisseria gonorrhea, also increase the risk of ectopic pregnancy, and a history of salpingitis increases the risk of ectopic pregnancy 4-fold. The incidence of tubal damage increases after successive episodes of PID (ie, 13% after 1 episode, 35% after 2 episodes, 75% after 3 episodes). 2- History of previous ectopic pregnancy

After 1 ectopic pregnancy, a patient incurs a 7- to 13-fold increase in the likelihood of another ectopic pregnancy.

3- History of tubal surgery and conception after tubal ligation

Previous tubal surgery has been demonstrated to increase the risk of developing ectopic pregnancy such as fimbrioplasty, tubal reanastomosis, and lysis of peritubal or periovarian adhesions.

4- Smoking

Cigarette smoking has been shown to be a risk factor for ectopic pregnancy development. Studies have demonstrated an elevated risk ranging from 1.6 to 3.5 times that of nonsmokers. A dose-response effect has also been suggested.

5- Use of oral contraceptives or an intrauterine device

All contraceptive methods lead to an overall lower risk of pregnancy and therefore to an overall lower risk of ectopic pregnancy. However, among cases of contraceptive failure, women at increased risk of ectopic pregnancy compared with pregnant controls included those using progestin-only oral contraceptives, progestin-only implants, or IUDs and those with a history of tubal ligation .

Nevertheless, if a woman ultimately conceives with an IUD in place, it is more likely to be an ectopic pregnancy. 6- Use of fertility drugs or assisted reproductive technology

Ovulation induction with clomiphene citrate or injectable gonadotropin therapy has been linked to a 4-fold increase in the risk of ectopic pregnancy in a case-control study. This finding suggests that multiple eggs and high hormone levels may be significant factors. In addition, the risk of ectopic pregnancy and heterotopic pregnancy (ie, pregnancies occurring simultaneously in different body sites) dramatically increases when a patient has used assisted reproductive techniques—such as such as in vitro fertilization (IVF) .

7- Increasing age

The highest rate of ectopic pregnancy occurs in women aged 35-44 years. A 3- to 4-fold increase in the risk of developing an ectopic pregnancy exists compared with women aged 15-24 years. One proposed explanation suggests that aging may result in a progressive loss of myoelectrical activity in the fallopian tube; myoelectrical activity is responsible for tubal motility.

8- Salpingitis isthmica nodosum

Salpingitis isthmica nodosum is defined as the microscopic presence of tubal epithelium in the myosalpinx or beneath the tubal serosa. These pockets of epithelium protrude through the tube, similar to small diverticula. The etiology of salpingitis isthmica nodosum is unclear, but proposed mechanisms include postinflammatory and congenital changes, as well as acquired tubal changes, such as those observed with endometriosis 9- Other

Other risk factors associated with increased incidence of ectopic pregnancy include anatomic abnormalities of the uterus such as a Tshaped or bicornuate uterus, fibroids or other uterine tumors, previous abdominal surgery, failure with progestin-only contraception, and ruptured appendix.

Question 40

Ectopic pregnancy
Dx

Answer 40

Diagnosis

1—-Serum β-HCG levels

In a normal pregnancy, the β-HCG level doubles every 48 hours until it reaches 10,000-20,000mIU/mL. In ectopic pregnancies, β-HCG levels usually increase less. Mean serum β-HCG levels are lower in ectopic pregnancies than in healthy pregnancies.

No single serum β-HCG level is diagnostic of an ectopic pregnancy. Serial serum β-HCG levels are necessary to differentiate between normal and abnormal pregnancies and to monitor resolution of ectopic pregnancy once therapy has been initiated.

The discriminatory zone of β-HCG :- the level above which an imaging scan should reliably visualize a gestational sac within the uterus in a normal intrauterine pregnancy) is as follows: 1500-1800 mIU/mL with transvaginal ultrasonography, but up to 2300 mIU/mL with multiple gestates , 6000-6500 mIU/mL with abdominal ultrasonography.

Absence of an intrauterine pregnancy on a scan when the β-HCG level is above the discriminatory zone represents an ectopic pregnancy or a recent abortion. 2—-Ultrasonography

Ultrasonography is probably the most important tool for diagnosing an extrauterine pregnancy. Transvaginal ultrasonography, or endovaginal ultrasonography, can be used to visualize an intrauterine pregnancy by 24 days postovulation or 38 days after the last menstrual period (about 1 week earlier than transabdominal ultrasonography). An empty uterus on endovaginal ultrasonographic images in patients with a serum β-HCG level greater than the discriminatory cut-off value is an ectopic pregnancy until proved otherwise. Color-flow Doppler ultrasonography improves the diagnostic sensitivity and specificity of transvaginal ultrasonography, especially in cases in which a gestational sac is questionable or absent.

3—-Laparoscopy

Laparoscopy remains the criterion standard for diagnosis; however, its routine use on all patients suspected of ectopic pregnancy may lead to unnecessary risks, morbidity, and costs. Moreover, laparoscopy can miss up to 4% of early ectopic pregnancies. Laparoscopy is indicated for patients who are in pain or hemodynamically stable.

4—Culdocentesis

Aspiration of peritoneal fluid from posterior vaginal pouch (haemoperitonial fluid )

Question 41

Ectopic pregnancy
Mgx

Answer 41

Management :- Therapeutic options in ectopic pregnancy are as

follows:

1- Expectant management

2- Medical management

3- Surgery Expectant management::-Candidates for successful expectant management should be

-asymptomatic and have no evidence of rupture or hemodynamic instability.

-Low serum HCG < 1500 IU/L

-Candidates should demonstrate objective evidence of resolution (eg, declining β-HCG levels).Close follow-up and patient compliance are of paramount importance, as tubal rupture may occur despite low and declining serum levels of β-HCG.

Medical management::–Local injection of PG , potassium chloride , hyperosmolar glucose or methotrexate .

Methotrexate is the standard medical treatment for unruptured ectopic pregnancy. A single-dose IM injection is the more popular regimen. The ideal candidate should have the following:

1- Hemodynamic stability

2-No severe or persisting abdominal pain 3-The ability to follow up multiple times 4-Normal baseline liver and renal function test results 5-Mass size < 5 cm .

6-Serum HCG < 3000 IU/L 7-NO evidence of cardiac activity .

Absolute contraindications to methotrexate therapy include

1- Existence of an intrauterine pregnancy

2- Immunodeficiency 3- Moderate to severe anemia, leukopenia, or thrombocytopenia

4- Sensitivity to methotrexate

5- Active pulmonary or peptic ulcer disease

6- Clinically important hepatic or renal dysfunction

7- Breastfeeding

8- Evidence of tubal rupture

Surgical treatment::– Laparoscopy has become the recommended surgical approach in most cases.

Laparotomy is usually reserved for patients who are

1–hemodynamically unstable

2–patients with cornual ectopic pregnancies;

3–preferred method for surgeons inexperienced in laparoscopy

4–patients in whom a laparoscopic approach is difficult such as morbid obesity and adhesion .

Salpengectomy (best) or salpengestomy ( if contralateral tube is unhealthy )

Fertility following ectopic pregnancy

Previous history of infertility has been found to be the most significant factor affecting postsurgical fertility when the contralateral fallopian tube is normal, the subsequent fertility rate is independent of the type of surgery. Intrauterine pregnancy rate following ectopic pregnancy between 50-70% .

Recurrent ectopic pregnancy occur in 6-16 % of women with previous history of ectopic .

Trimester

Vaginal bleeding, abdominal/pelvic pain of any degree, or both during early pregnancy represents a threatened miscarriage. Approximately a fourth of all pregnant women have some degree of vaginal bleeding during the first 2 trimesters. About half of these cases progress to an actual miscarriage. Bleeding and pain accompanying threatened miscarriage is usually not very intense. Threatened miscarriage rarely presents with severe vaginal bleeding. On vaginal examination, the internal cervical os is closed and no cervical motion tenderness or tissue is found. Diffuse uterine tenderness, adnexal tenderness, or both may be present. Threatened miscarriage is defined by the absence of passing/passed tissue and the presence of a closed internal cervical os. These findings differentiate threatened miscarriage from later stages of a miscarriage. presented emergency like pain bleeding

Question 43

Miscarriage
Maternal factors

Answer 43

Chronic maternal health factors include the following:

• Maternal insulin-dependent diabetes mellitus (IDDM): As many as 30% of pregnancies in women with IDDM result in spontaneous miscarriage, predominantly in patients with poor glucose control in the first trimester.

• Severe hypertension

• Renal disease

• Systemic lupus erythematosus (SLE)

• Hypothyroidism and hyperthyroidism

Acute maternal health factors include the following:

• Infections (eg, rubella, cytomegalovirus [CMV], and mycoplasmal, ureaplasmal, listerial, toxoplasmal infections)

• Trauma

Severe emotional shock may also cause first- and second-trimester

miscarriages. Other factors that may contribute to miscarriage

Exogenous factors include the following:

• Alcohol

• Tobacco

• Cocaine and other illicit drugs

Anatomic factors include the following:

Congenital or acquired anatomic factors are reported to occur in 10-15% of women who have recurrent spontaneous miscarriages.

• Congenital anatomic lesions include müllerian duct anomalies (eg, septate uterus, diethylstilbestrol [DES]-related anomalies). Müllerian duct lesions usually are found in second-trimester pregnancy loss.

• Anomalies of the uterine artery with compromised endometrial blood flow are congenital.

• Acquired lesions include intrauterine adhesions (ie, synechiae), leiomyoma, and endometriosis.

• Other diseases or abnormalities of the reproductive system that may result in miscarriage include congenital or acquired uterine defects, fibroids, cervical incompetence, abnormal placental development

Endocrine factors include the following:

• Endocrine factors potentially contribute to recurrent miscarriage in 10-20% of cases.

• Luteal phase insufficiency (ie, abnormal corpus luteum function with insufficient progesterone production) is implicated as the most common endocrine abnormality contributing to spontaneous miscarriage.

• Hypothyroidism, hypoprolactinemia, poor diabetic control, and polycystic ovarian syndrome are contributive factors in

pregnancy loss.

Infectious factors include the following:

• Presumed infectious etiology may be found in 5% of cases. • Bacterial, viral, parasitic, fungal, and zoonotic infections are associated with recurrent spontaneous miscarriage.

Immunologic factors include the following:

• Immunologic factors may contribute in up to 60% of recurrent spontaneous miscarriages.

• Both the developing embryo and the trophoblast may be considered immunologically foreign to the maternal immune system.

• Antiphospholipid antibody syndrome generally is responsible for more second-trimester pregnancy losses than first-trimester losses.

• Miscellaneous factors

• Miscellaneous factors may account for up to 3% of recurrent spontaneous miscarriages. Other contributing factors implicated in sporadic and recurrent spontaneous abortions include environment, drugs, placental abnormalities, medical illnesses, and male-related causes. Among the risk factors for early pregnancy loss are very low or very high body mass index, a history of previous miscarriages, smoking, alcohol use, working night shifts, air pollution, and exposure to pesticides.

Question 44

Miscarriage
Prognosis

Answer 44

Prognosis

• The prognosis for a successful pregnancy depends upon the

etiology of previous spontaneous miscarriages, the age of the patient, and the sonographic appearance of the gestation.

• Correction of an endocrine abnormality in women with recurrent miscarriage has the best prognosis for a successful pregnancy (>90%).

• In women with an unknown etiology of prior pregnancy loss, the probability of achieving successful pregnancies is 40-80%.

Question 45

Miscarriage

Emergency Department Care: Management

Answer 45

Treat all patients with vaginal bleeding of any etiology as follows:

• Determine hemodynamic stability and treat instability. If the patient is in hemorrhagic shock, treatment includes the Trendelenburg position, oxygen, aggressive fluid resuscitation (at least 2 large-bore IV lines with lactated Ringer [LR] solution or

normal saline, wide open), and hemotransfusion.

• Determine pregnancy status (qualitative and quantitative).

• Make laboratory determination of hematocrit (Hct) level and Rh status.

• Perform a pelvic examination to determine the rate of bleeding; presence of blood clots or products of conception; and condition of cervical os, cervix, uterus, and adnexa.

• Perform pelvic ultrasonography to determine intrauterine and/or extrauterine contents (fetal heart activity) and/or to clinically classify spontaneous miscarriage.

Question 46

Missed miscarriage

Answer 46

Missed miscarriage:-Treatment may vary depending on gestational age : • Expectant management:- within few weeks may aborted spontaneously (risk of DIC and septicemia)

• medical management:- By using uterotonic therapy alone or in conjugation with antihormone therapy. The advantages of medical therapy is that no surgical procedures are needed if it is successful. Passage of tissue should happen within a few days of receiving medical therapy. If it is not successful, then a surgical approach may follow. The risks for medical therapy include bleeding, infection, possible incomplete abortion, and possible failure of the medication to work.

The first tablet, mifepristone (ante progesterone) , will be taken by mouth. . If the patient start to bleed heavily and pass clots after taking this first tablet, there is no need for any further medication. If she is only spotting blood, continue with the second medicine, misoprostol (uterotonic agent). Insert misoprostol, into the vagina 36-48 hours after taking the mifepristone.postintravaginal misoprostol 400 mcg, whereas only 16.7% of women achieved this after 2 h of 600 mcg. The 600-mcg group had slightly greater adverse effects (eg, bleeding, abdominal pain, fever >38ºC).Dosage intended for cervical ripening can induce abortion in some patients. Oral doses of 100-400 mcg can be combined with vaginal insertion of prostaglandins to enhance cervical dilatation. primigravid women (6-11 wk gestation), 93.3% achieved dilatation of the cervix of 8 mm or greater after 3 h

Surgical route:- evacuation of uterus by D&C under local or general anesthesia , cervical dilatation can be assumed by cervical priming agent such as PG agonist ( misoprostol ), at least 2 hr. before operation ,this reduce the pressure required for dilatation of the cervix & hence the risk of uterine perforation . The advantage of D&C is that the procedure is scheduled and occurs at a known time.

Complications of D&C include

Risk of GA, bleeding, Infection, Retained products, Uterine perforation & Asherman syndrome (intrauterine adhesion result from vigorous curettage)

Question 47

Endometriosis and infertility

Answer 47

in the more severe stages of endometriosis, there is commonly anatomical distortion, with periadnexal adhesions and destruction of ovarian tissue when endometriomas develop.

A number of possible and variable mechanisms have been postulated to connect mild endometriosis with infertility including negative effects on ovarian reserve, ovulation dysfunction, sperm survival in the female genital tract and egg quality (and thus embryo quality).

However, a specific diagnosis requires visualization & in uncertain cases , biopsy of lesions , either at laparoscopy or laparotomy .

.

2- Non - invasive tests

a-Ca 125 level : non - specific.

b- ultrasound : is of limited value , helpful when there is endometriomas or chocolate cysts) .

c- MRI : is of little benefit also , useful when there are ovarian cyst , or invasion of surrounding organs such as bowel , bladder , recto vaginal septum 3- Laparoscopy: remains the gold standard means of diagnosing endometriosis . endometriotic lesions can be red, puckered, black ‘matchstick’ or appear white and fibrous.

Role of laproscopyis vital:

a. provides direct visualization of endometriotic lesions .

b. possibility to biopsy suspected areas .

c. allow staging of the disease .

d.It allow concurrent therapy at the time of laproscopy in the form of cautery or laser treatment in selected cases .

d. Allow checking patency of fallopian tubes.

A: Red lesions on peritoneum B: black ‘matchstick’lesions

C: white fibrous lesion.

Question 51

Endometriosis
Ttt

Answer 51

Surgical treatment

Conservative or definitive.

1. Conservative surgery Through laproscopy or open surgery . By eradicate vissible endometriotic lesions with diathermy or laser . also endometrioma treated in 2 ways either the cyst opened & drained , & base lasered , or do ovarian cystectomy . lysis of tubo - ovarian adhesions or do salpingostomy .

2- Definitive (radical ) surgery : TAH & BSO indications

a. severe symptomatology b.progressive disease .

c.women whose families are complete .

d. large adherent endometriotic cyst.

e.patient with deep - seated endometriosis involving the bowel or bladder .

so endometriosis remains a disorder of little hope of a perminant cure , & one with repeat recurrences throught the reproductive life . Malignant changes in endometriosis is very rare , usually involves ovarian endometriosis . it is either endometriod ca. or adenocanthoma.

1- Drug therapy:

a. NSAID

are helpful in reducing the severity of dysmenorrheal & pelvic pain .

b. Hormone therapy:

medical treatment of endometriosis aimed at the prevention of menstruation using sex steroids in various ways . oestrogens , androgens, progestogens , & combinations have been used .

1.COC

use of continuous COC & in increasing dosage for up to 9 months to induce a state of pseudopregnancy ; with anovulation & amenorrhea , would lead to necrosis & absorptiopn of decidualized endometriosis . S/E weight gain , nausea , vomiting , breakthrough bleeding . 2-Danazole & Gestrinone :

it is mild androgenic , antiprogestogenic , antigonadotrophic , immunosuppressive effect , also has direct inhibition of endometrial cell growth, used in the past but are no longerv appropriate.

Dose Danazole 400 -800 mg / day Gesrinone 2.5 mg twice weekly used in courses for 3 - 6 months .

Side effects androgenic S/E e.g. weight gain , greasy skin , acne, deepening of voice .

longer - term administration may leads to alterations in lipid profile , or liver function , which needs to be monitored .

3- progestogens

such as medroxyprogesterone acetate or dydrogesterone .

given on continuous basis and the levonorgestrel intrauterine system (LNG-IUS) (Mirena) .

4- GnRH agonists Temporary induction of pseudo - menopause . used as intranasal or subcutaneous routes or slow - release depot formulation for one month . S/E hot flush , night sweats , atrophic vaginitis , long - term use may leads to osteoporosis . • a newer class of drug called aromatase inhibitors that inhibit the

• action of the enzyme aromatase, which converts androgens into oestrogens and is over expressed in endometriotic tissue.

• Further research needed to be used in refractory cases.

Question 52

Adenomyosis

Answer 52

is a disorder in which endometrial glands & stroma are found deep within the myometrium.

Predisposing factors

1. usu. occur in multiparous women ; repeated pregnancies may predispoes to extension of endometrium into the myometrium .
2. Age; in late thirties or early forties ( near the end of reproductive life ).
3. Vigorous curettage; may leads to damage of the uterine wall, thus allowing acess by the endometrium
4. Cystic glandular hyperplasia of the endometrium .
5. High socio - economic status Pathology

uterus is usu. enlarged (symmetrical enlargement ) , lesion may be localized or diffuse .

Clinical features

the principal symptom is menorrhagia (perhaps from interference with normal uterine haemostatic mechanisms) , progressive secondary dysmenorrhea , pelvic discomfort , & dysparunnia.

is difficult pre -op.

1. Ultrasound; may be useful when adenomyosis is marked & localized to one area.
2. MRI

• 3. Pathological examination of the hysterectomy specimen . where it is identified in 40% of uteri from a general female population of reproductive age.

Treatment Conservative surgery & medical treatment poorly developed .

Hysterctomy ; is the only definitive treatment .

Question 53

Contraception
Iucd

Answer 53

1-inert devices such as lippes loop.

2-devices with various applications of copper designed to increase

effectiveness & decrease surface area &so decrease side effects particularly the menorrhagia & dysmenorrheal e.g. copper T &7 & now Multiload & Nova T.

3-Medicated I.U.C.D releasing low concentrations of progesterone or norgestrel e.g • The 52 mg LNG-IUS (Mirena®) . 20 ug levonorgestrel /day & lasting for 5 years, advantage is menstrual blood loss is very substantially reduced 90% at 1 year.

• and the 13.5 mg LNGIUS

• (known as Jaydess) is licensed for 3 years for contraceptive use.

Question 54

Contraception
Iucd
Mechanism of action

Answer 54

IUDs work by inhibiting fertilisation by direct toxicity . An inflammatory reaction within the endometrium can also have an antiimplantation effect. Copper is toxic to the ovum and the sperm and the copper content of the cervical mucus inhibits sperm penetration as well

• . LNG-IUS works primarily by its effect on the endometrium, which prevents endometrial proliferation and implantation. Its progestogenic effect on thickening the cervical mucus also

• impedes entry of sperm The LNG-IUS does not prevent ovulation. • The Cu-IUD duration of use is between 3 and 10 years, depending on the device used and age of woman at insertion. If a woman has a CuIUD inserted at 40 years or above, it can be left in situ until the menopause.

• For women who have a 52 mg LNG-IUS inserted at 45 years or over, the device can be left for contraceptive purposes until the menopause.

Question 55

Non-contraceptive health benefits of LNGIUS (52 mg)

Answer 55

1-pregnancy.

2-multiple fibroids.

3-congenital uterine abnormality.

4-acute or sub acute PID or active vaginal inflammation. 5-ca. of the cervix or of body of uterus.

6-valvular heart disease (risk of bacterial endocarditic). 7-abnormal uterine bleeding.

8-known allergy to copper if a copper IUCD is being chooses.

Question 57

Contraception
IUD
Insertion
Se

Answer 57

Insertion:

An IUD can be fitted at any point in the cycle provided there is no risk of pregnancy.

Postpartum insertion; should be delayed 8 weeks to decrease the risk of expulsion & perforation especially in lactating woman.

IUD can be inserted immediately after abortions; although expulsion rates may be higher in second trimester abortion.

Efficacy; during first year after insertion between 2-3% of women will conceive. Levonorgestril is more effective 0.1. Side effects:

1-Menstrual disturbances: the effects of IUD on the endometrial

particularly. The local PGs tens to cause increase menstrual bleeding & dysmenorrheal. Also IUD may cause irregular bleeding. In contrast the levonorgestril IUD decrease the blood loss. 2-Perforation; usually occur at the time of insertion;& it is often

unnoticed . It is about 1:1000 & most frequently is through the uterine fundus. It should be suspected when at the routine follow up (6 weeks later) there e is absence of the thread (other 2 possibilities is either expulsion of the device or it is rotated within uterine cavity). Pelvic u/s or x-ray will help to localize the device. Intraperitoneal devices can be recovered through laparoscope or sometime laprotomy. 3-expulsion; rate vary from 1-20 women, most commonly in the first 3 months of use.

• 4-ectopic pregnancy; women using IUD has 80% decrease in the risk of ectopic pregnancy compared with women not using contraception.but if pregnancy occur with IUCD more likely it is ectopic pregnancy.

• The ectopic pregnancy rate for Cu-IUD users is 0.02 per 100 WY (0.3–0.5 per 100 WY for those not using contraception)

5-pelvic infection; infection is most likely to occur during the 20 days following insertion

Actinomycosis occur more with IUCD. -pregnancy with IUCD in place; increase risk of about 3 x & removal of IUCD will decrease the risk of abortion. If the IUCD left in place there is slight risk of intrauterine infection, preterm labour,second trimester miscarriage &APH, but most pregnancies are uncomplicated & the device is delivered with the placenta.

Question 58

Contraception
Coc
Formula
Mode of action
Advantage

Answer 58

Formulations:- It contains both estrogen(usually Ethinyl oestradiol or Menstranol) & a progesterone. Previously use high dose pills (100 ug of estrogen), but now decrease the dose of estrogen to 20-50 ug; most women use 30-35 ug estrogen (low- dose pills). The progesterone either 1 st or 2 nd or 3 rd generation  The pill is taken for 21 days followed by a 7-day break

during which time withdrawal bleeding usually occurs. The pill should be taken at the same time each day, bed time is convenient. If the woman forgets to take the pill one night she can take it the next morning.

 Combined pills are available as monophonic

(preparation in which every pill in the pocket contains the same dose of steroids); & biphasic & triphasic pills ; in which the dose of both steroids changes once or twice during the cycle so that the regimen will mimics the normal cycle. Mode of action:-

 The principle mode of action of COC is the inhibition of ovulation. Estrogen inhibits FSH (suppressing the development of ovarian follicles, while progestogens inhibit the development of LH surge.

 Additional contraceptive effects include changes in the cervical mucus characteristics interfering with sperm transport, a possible alteration in the tubal motility, endometrial atrophy with impaired uterine receptivity. Advantages:-

1. Menstrual periods are usually lighter, shorter & more regular during the pill use, less painful & premenstrual symptoms less troublesome.
2. Decrease the incidence of iron deficiency anemia by decreasing menstrual blood loss.
3. Decrease incidence of benign breast lumps, functional ovarian cysts, endometriosis, acne & possibly PID.
4. COC use protects against ovarian & endometrial cancer (due to decrease in the number of ovulations & therefore rupture of ovarian capsule).  There is also a 50 per cent reduction in ovarian and

endometrial cancers which continues for 15 years after stopping the CHC.

 5.There is a possible protective effect against

rheumatoid arthritis, thyroid disease and duodenal ulceration.

Amenorrhea when high –dose pills. Exclude pregnancy & sometimes can be treated by induction of ovulation. 2.Weight gain, fluid retention, headache, nausea, & vomiting, chloasma, mood changes, loss of libido, mastalgia, breast enlargement & greasy skin. B-Serious S/E :

 1.CVS: on venous side; increase risk of venous

thrombosis & pulmonary embolism. In dosedependent pattern related to the amount of estrogen in the pill. Estrogen increase platelet count & platelet adhesiveness & decrease ant thrombin in blood.

 This risk is the most during the first year of CHC use.

On arterial side: including hypertension, CVA,&

coronary heart disease. Increase risk was only seen on smoker woman on the pill. 2.Carbohydrate metabolism: high dose pills will decrease carbohydrate tolerance.

3.Malignancy: small increase in breast cancer & that the risk persisted for 10 years after stopping the pills especially if she take the pills before the birth of the first child.

Also small increase in the risk of carcinoma of cervix. Liver cancer; benign hepatic adenoma is rare complication. Interaction with drugs:

 Effectiveness of the combined oral contraceptive pill (COCP) (and all other methods) is not affected by administration of most broad-spectrum antibiotics.

 Barbiturates, sulphonamide, rifampicin, phenytoin & most anticonvulsants will increase activity of liver enzymes that metabolize the steroids.

 Effect on pregnancy: no increase in the incidence of

congenital abnormality in woman who has taken the pills after pregnancy has started.

 Follow up: B.P checked at 6, 12 months, then annually, Pap smear annually .examine breast each year.

Question 60

Missed-pill guidelines for COC

Answer 60

 If ONE pill has been missed (more than 24 hours and up to 48 hours late) .

 Continuing contraceptive cover  • The missed pill should be taken as soon as it is

remembered • The remaining pills should be

continued at the usual time.

 Minimizing the risk of pregnancy  Emergency contraception (EC) is not usually

required. If TWO OR MORE pills have been missed (more than 48 hours late

 Continuing contraceptive cover •  The most recent missed pill should be taken as soon as possible •

 The remaining pills should be continued at the usual time •  Condoms should be used or sex avoided until

seven consecutive active pills have been taken.  Minimising the risk of pregnancy  If pills are missed in the first week (Pills 1 - 7) .

 EC should be considered if unprotected sex occurred in the pill-free

interval or in the first week of pill-taking  If pills are missed in the second week (Pills 8 - 14)  No indication for EC if the pills in the preceding 7 days have been taken

consistently and correctly (assuming the pills thereafter are taken

correctly and additional contraceptive precautions are used).  .  If pills are missed in the third week (Pills 15 - 21)  OMIT THE PILL-FREE INTERVAL by finishing the

pills in the current pack (or discarding any placebo

tablets) and starting a new pack the next day.

Question 61

Evra patch

NuvaRing

Answer 61

 



With this patch 20 μg of ethinyl estradiol and 150 μg of norelgestromin are released every 24 hours.

It is the first transdermal contraceptive applied once weekly for 3 weeks followed by a patch-free week (3 weeks on, 1 week off).

The Pearl index is 1.24 per 100 WY NuvaRing

  



releases 120 μg of etonogestrel (ENG) and 15 μg of ethinyl estradiol daily. It is 54 mm in diameter and 4 mm thick.

It is placed vaginally once every 3 weeks and following a 1week ring-free interval a new ring is inserted.

Efficacy and cycle control are comparable to the COCs. Side-effect profile is also similar to that of COCs.

However, women have reported more vaginal symptoms of vaginitis, leukorrhoea, foreign body sensation, coital problems and expulsion.

Question 62

Progesterone- only contraception:
Efficacy
Indications
UKMEC Category
Se

Answer 62

Available as oral pills, implants, long acting injectables, & recently hormone – releasing IUCD.

Mechanism of action:

Given in high doses e.g. injectables, progestogens inhibit ovulation. In low doses; ovulation may be inhibited often inconsistently. By all routes progestogens affect cervical mucus reducing sperm penetrability & transport & all have an effect on the endometrium which probably compromises implantation. S/E:

All low dose progesterone – only methods are associated with high incidence of irregular bleeding because ovulation inhibited inconsistently .Also progestogens may alter the vasculature of the endomrtium increase the chance of bleeding.

Efficacy:

 

POP has a higher failure rate than COC.

Failure rates for traditional POPs vary from 0.3 to 8.0 per 100 WY. The decrease efficacy is due in part that many women continue to ovulate & in part because the POP has a shorter half- life in the circulation. Indications of POP:

1.In women in whom estrogen is absolutely or relatively contraindicated as women with CVS risk factors, migraine, D.M or mild hypertension.

2. Lactating women since estrogen impairs milk production.  POP: UKMEC Category 3 – Risks generally outweigh benefits  Current and history of ischaemic heart disease and stroke –

continuation of the method  Past history of breast cancer and no evidence of recurrence for 5

years  HIV – on antiretroviral therapy (drug interactions)  Cirrhosis – severe (decompensated)  Liver tumours – hepatocellular adenoma and malignant

hepatoma  SLE – positive or unknown antiphospholipid antibodies  POP: UKMEC Category 4 – Unacceptable health risk and should not be used  Breast disease – current breast cancer S/E:

1.Irregular vaginal bleeding.

2.High incidence of functional ovarian cysts due to effect on ovarian activity.

3.Headache, nausea, bloating, breast tenderness & mood

changes, oily skin & acne.

4.Long –term risks: very small increase in the risk of carcinoma breast after prolonged use of POP (Depo-

Provera confers a high degree of protection against endometrial ca.).

Answer 63



 

TRADITIONAL POPS (Micronor, Noriday, Norgeston*, Femulen

> 3 hours late (>27 hours since the last pill was taken)

Take a pill as soon as remembered.

If more than one pill has been missed just take one pill. Take the next pill at the usual time. This may mean taking two pills in one day. This is not harmful. An additional method of contraception (condoms or abstinence) is advised for the next 2 days (48 hours after the POP has been taken).

Question 64

Subcutaneous DMPA (Sayana Press) 104 mg given

subcutaneously every 13 weeks. It can be injected into the upper anterior thigh or anterior abdomen . S/E:

1.Irregular vaginal bleeding (treated by administration of estrogen simply by adding the combined pills).

2.Amenorrhea.

3.Delayed fertility; it may take 1 year for normal fertility to return following cessation of depo provera.

 4.Decrease bone marrow density (BMD); Amenorrhea →hypooestrog. →↓BMD.

 5.Weight gain  The average weight gain among women using DMPA is between 2 and 6 kg.

Question 66

PROGESTOGEN-ONLY IMPLANT

Answer 66

Nexplanon  is the only POI available in the UK. It has replaced Implanon.

 It is a single rod which contains 68 mg of etonorgestril ENG in a

membrane of ethylene vinyl acetate. It is licensed for 3 years.  Nexplanon is radio-opaque  . Nexplanon® is a flexible rod (40 mm × 2 mm) and is inserted  subdermally 8 cm above the medical epicondyle, usually of the

non-dominant arm.

 Insertion  is conducted under local anaesthesia using a specially designed

insertion device.

Mode of action

 



The main mode of action is inhibition of ovulation .

Thickening of the cervical mucus prevents sperm penetration into the upper reproductive tract.

It also brings about changes in the endometrium making the environment unfavourable for implantation . Side effects

 irregular bleeding and oligomenorrhoea/ amenorrhoea.  Weight gain .

 Mood changes and loss of libido can occur.

 Acne can improve, occur or worsen whilst using the implant.

 Complications with removal  include deeply sited, non-palpable, broken or migrated implants. As Nexplanon contains barium sulphate it is radio-opaque. Hence it can be identified on X-rays. Ultrasound and MRI can also be used to locate the implants.

Question 67

Emergency contraception

Answer 67

Is any drug or device used after intercourse to prevent pregnancy, to prevent implantation of a fertilized egg.

1Yuzpe regimen. 2 tablets of high –dose estrogen (100ug) & 500ug

levonorgestrel repeated after 12 hours. S/E nausea & vomiting. The dose

should be given within 72 hours of coitus.

 2.Levonorgestrel 1.5 mg once up to 3 days. Replace yuzpe regimen.

 it works mainly by inhibiting ovulation. It prevents follicular rupture.  It can be used more than once in a cycle.

 3.IUCD is highly effective postcoital contraception with failure rate <

1%. It is used up to 5 days after coitus.or 5 days after ovulation  should be the first-line choice, particularly if the woman intends to

continue the IUD as long-term contraception .

 When used for EC, its effect on the endometrium is thought to prevent

implantation if fertilization has occurred   

  

   



4. ellaone-ulipristal acetate 30mg single dose tablet If vomiting occurs within 3 hours, another tablet should be taken. Ulipristal is not recommended to be used more than once per cycle as the safety of efficacy of repeated exposure has not been assessed .

Is progesterone receptor modulator .

Its primary mode of action is thought to be inhibition or delay of ovulation. It can prevent ovulation after the LH surge has started. Effective up to 120 hours after coitus.

Levo norgestrel effective 69% Ulipristal 85%.

Oral EC is much less effective than the Cu-IUD for EC and is estimated to prevent only two-thirds of pregnancies.

• Effective ongoing contraception should be started after EC.

Question 68

sterilisation

Answer 68

 Sterilisation is a permanent and usually an irreversible method of contraception .

1-Female sterilization  It involves blocking both fallopian tubes by laprotomy,

mini-laprotomy, & more commonly by laparoscope or via hysteroscopy.

Bilateral salpingectomy or hysterectomy may be

preferable when there is coexistent gynecological

pathology. Methods of tubal occlusion:

 1.Ligation (using absorbable or non- absorbable sutures)  The Pomeroy technique is the most widely used ligation technique .

2.Electrocautery.

3.Rings.

4.Clips.

5.Laser (co2 laser).

 6.Chemical agents instilled into fallopian tubes e.g.

quinacrine.

 The failure rate for female sterilisation is 1 in 200. Hysteroscopic sterilisation

 Micro-inserts made from nickel–titanium and stainless steel are inserted hysteroscopically through the cornual ends of both tubes.

 This can be performed under local anaesthesia and/or

intravenous sedation. These generate fibrosis around the devices and the tubes are occluded by 3 months after the procedure.

 Additional contraception needs to be used until a

hysterosalpingogram is performed at 3 months to confirm full occlusion of the tubes.

 It is an irreversible procedure and the failure rates quoted are the same as for the other methods of tubal occlusion. Complications:

A-Immediate complications

1. Complication of G.A.
2. Vascular damage or damage to bowel or other internal organs especially with electrocautery.
3. Gas embolism.
4. Thrombo-embolism.  5. Wound infection. B- Long –term complications  1.Menstrual disorders. There is no evidence to suggest

that there is an increased incidence of bleeding problems and consequently an increased hysterectomy rate after tubal occlusion.

2.Abdominal pain & dysparunia (more common after cautery).

3.Psychological problems & psycho-sexual problems.

4.Bowel obstruction from adhesions (very rare). Vasectomy (male sterilization)

Division or occlusion of the vas deferens prevents the passage of

sperm using clips or diathermy or injection of sclerosing agents as silicone.

 

Efficacy: failure rate is 1 in 2000.

The procedure can be carried out under a local anaesthetic and is safer than female sterilisation. Following the procedure, men should be advised to use effective contraception until two consecutive semen samples 4 weeks apart confirm azoospermia. (The first sample should be taken at least 8 weeks after surgery.)

Complications

A-Immediate

1.

Scrotal hematoma, wound infection.

2. Up to 2 % men fail to have azospermia in which case vasectomy repeated.

Question 69

The definitive diagnosis of a molar pregnancy

Removal of a molar pregnancy

Answer 69

The definitive diagnosis of a molar pregnancy is made by

histological examination.

Ploidy status and immunohistochemistry staining for p57, a paternally imprinted gene, may help in distinguishing partial from

complete molar pregnancies.

Removal of a molar pregnancy

Complete molar pregnancies are not associated with fetal parts, and therefore, suction removal is the method of choice for uterine removal irrespective of uterine size. Medical removal of a complete molar pregnancy should be avoided if possible, irrespective of the agents used.

Ultrasound guidance during removal and curettage may be of use to minimize the chance of perforation and to ensure that as much tissue as possible is removed.

Suction curettage is the method of choice for removal of partial molar pregnancies except when the size of fetal parts deters the use of suction curettage and then medical removal can be used.

Anti-D prophylaxis is recommended following removal of a molar pregnancy.

Excessive vaginal bleeding can be associated with surgical management of molar pregnancy. There is theoretical concern over the routine use of oxytocic agents, including ergometrine and misoprostol,because of the potential to embolism and disseminate trophoblastic tissue through the venous system.

In the event of life-threatening haemorrhage or ongoing bleeding, oxytocic infusions may be used.

Theca-lutein ovarian cysts tend not to be symptomatic and typically regress after molar evacuation. In extreme cases, these may be aspirated if symptomatic, but oophorectomy is not performed except when torsion leads to extensive ovarian infarction

Question 70

In what circumstances should a repeat surgical removal be indicated and what is the timing?

How should suspected ectopic molar pregnancy in women be managed?

Answer 70

In what circumstances should a repeat surgical removal be indicated and what is the timing?

Women with persistent heavy vaginal bleeding and evidence of

retained pregnancy tissue on ultrasound examination may need a

repeat surgical removal and hCG is less than 5000 units/l. Expediting surgical management in the case of acute haemodynamic compromise is the priority and delay can be harmful.

How should suspected ectopic molar pregnancy in women be managed?

women with ectopic pregnancy suspected to be molar in nature should be managed as any other case of ectopic pregnancy. If there is a local tissue diagnosis of ectopic molar pregnancy, the tissue should be sent to a center with appropriate expertise for pathological review.

Twin pregnancy of a viable fetus and presumptive coexistent molar pregnancy

No pathologic or initial clinical feature accurately predict which patient will ultimately develop GTN ,so serial B-hCG level fallowing molare evacuation can used to effectively monitor patient with GTN development

Titer are monitored fallowing uterine evacuation at least every 1to

2week until they become undetectable

For complete molar pregnancy, if hCG has reverted to normal within 56 days of the pregnancy event then follow-up will be for 6 months from the date of uterine removal.

If hCG has not reverted to normal within 56 days of the pregnancy event then follow-up will be for 6 months from normalization of the hCG level.

Follow-up for partial molar pregnancy is concluded once the hCG has returned to normal on two samples, at least 4 weeks apart.

Women who have not received chemotherapy no longer need to have hCG measured after any subsequent pregnancy event.

PROFELACTIC CHEMOTHERAPY

Chemotherapy can be administered to help prevent GTN development in high risk patient who are:

 unlikely to compliant  whom B-hCG surveillance is not available  age>40  history of molar pregnancy with an excessively high titer prior to evacuation

However, formed villous structures are characteristically absent .Gestational choriocarcinoma initially invades the endometrium and myometrium but tends to develop early blood-borne systemic metastases. Most cases develop fallowing evacuation of a molar pregnancy, but this tumor may also fallow a non-molar pregnancy. the diagnosis of choriocarcinoma is delayed fure months due to subtle signs and symptoms. Most patients present with. intermenstrual bleeding, and high B-hCG levels are detected

Thus, abnormal bleeding for more than 8weeks following any pregnancy warrants evaluation With B-hCG testing to exclude a new pregnancy or GTN. Less Frequently, the diagnosis is made in an asymptomatic woman by an incidental positive pregnancy test In part because of the typical delay to diagnosis, choriocarcinomas following term pregnancies are associated with high-risk features and a higher mortality rate than GTN following non-molar abortions.

Placental-Site Trophoblastic Tumor

This tumor consists predominantly of intermediate trophoblasts at the placental site. It is a rare GTN variant with unique disease behavior. Placental-site trophoblastic tumor (PSTT) can follow any type of pregnancy but develops most commonly following a term gestation. Typically, patients have irregular bleeding months or years after the antecedent pregnancy, and the diagnosis is not entertained until endometrial sampling has been performed. PSTT tends to infiltrate only within the uterus, disseminates late in its course, and produces low B-hCG

levels Of interest, an elevated proportion of free B-subunit can help to discriminate it from other GTN types if the endometrial biopsy is equivocal .

For those with stage I disease but high-risk tumor features, chemotherapy can be considered. When this tumor does spread, the pattern mirrors that of gestational choriocarcinoma. Metastases often spread to the lungs, liver, Hysterectomy is the primary

treatment for non-metastatic PSTT due to its relative insensitivity

to chemotherapy. In particularly motivated patients, fertilitysparing procedures have mixed results Metastatic PSTT has a much poorer prognosis than its pos-tmolar GTN counterparts. As a result, aggressive combination chemotherapy is indicated. Regimens of etoposide, methotrexate, and dactinomycin (actinomycin D) that alternate with etoposide and cisplatin (EMA/EP) are considered the most effective .

Epithelioid Trophoblastic Tumor

This rare trophoblastic tumor is distinct from gestational choriocarcinoma and PSTT. The preceding pregnancy event may be remote, or in some cases, a prior gestation cannot be confirmed Epithelioid trophoblastic tumor (ETI) develops from neoplastic transformation of chorionic-type intermediate trophoblast. Microscopically, this tumor resembles PSTT, but the cells are smaller and display less nuclear pleomorphism. Grossly, epithelioid trophoblastic tumor grows in a nodular fashion rather than the infiltrative pattern of PSTT. Hysterectomy is again the primary treatment due to presumed chemoresistance and because the diagnosis is usuallyconfirmed in advance by endometrial biopsy. Chemotherapy options mirror that for PSTT. More than one third of patients will present with metastatic disease and demonstrable chemoresistance to multiagent therapy.

Question 74

The indications used at Charing Cross Hospital for initiating chemotherapy treatment in patients with gestational trophoblast tumours.

Answer 74

1. Rising hCG in two or plateaued in three consecutive serum samples
2. Raised hCG level 6 months after evacuation (even if falling)
3. Histological evidence of choriocarcinoma
4. Metastases to the brain, liver, gastrointestinal tract, spleen, kidneys or other solid organs
5. hCG >20 000 IU/L more than 4 weeks after evacuation
6. Heavy vaginal bleeding or gastrointestinal/intraperitoneal bleeding
7. Lung or vaginal metastases >2 cm

Question 75

Gtn
Assessment

Answer 75

Assessment

Patients with GTN undergo a thorough pretreatment assessment to determine disease extent. The initial evaluation may be limited to pelvic examination, chest radiograph, and pelvic sonography or abdominopelvic computed tomography (CT) scanning. Laboratory tests include CBC,B-hCG levels, and measure of liver, renal, and thyroid function.

Although approximately 40 percent of patients will have micrometastases not otherwise visible on chest radiography. chest CT is not needed because these small lesions do not affect outcome

However, pulmonary lesions identified on chest radiograph should prompt CT of the chest and magnetic resonance (MR) imaging of the brain. Fortunately, central nervous system involvement is rare in the absence of neurologic symptoms or signs .Positron emission tomography (PET) may occasionally be useful to evaluate occult choriocarcinoma or relapse from previously treated GTN when conventional imaging is equivocal or fails to identify suspected Metastatic disease .

Question 76

Gtn
Staging

Answer 76

Stage I Disease confined to the uterus

Stage II GTN extends outside of the uterus but is limited to the genital structures (adnexa, vagina, broad ligament)

Stage Ill GTN extends to the lungs, with or without known genital

tract involvement

Stage IV All other metastatic sites

FIGO = International Federation of Gynecology and Obstetrics; GTN = gestational trophoblastic neoplasia.

Patients at low risk for therapeutic failure are distinguished from those at high risk by wing the modified prognostic scoring system of the World Health Organization (WHO) score of 0 to 6 and will

be considered to have low-risk disease The remainder will have a score of7 or higher and be assigned to the high-risk GTN group

Question 77

Gtn
Low-risk disease management

Answer 77

the current recommendation is that a repeated evacuation should only be considered if the hCG level is under 5000 IU/L and tissue is seen in the uterine cavity on ultrasound.For patients meeting the FIGO standard for low-risk treatment, the most widely used protocol is methotrexate given intramuscularly with oral folinic acid rescue following the schedule
The low-risk methotrexate and folinic acid chemotherapy treatment schedule.

The first course of treatment should be administered in hospital with the subsequent courses administered at home. This is because they have a higher risk of bleeding as therapy starts, particularly if the tumor shrinks rapidly with the initial chemotherapy. Bleeding usually responds well to strict bed rest and less than 1% of low-risk patients require emergency interventions such as embolization, vaginal packing or hysterectomy

For low-risk patients with lung metastases visible on their chest radiographs perform MRI of the head and if normal to add CNS prophylaxis with intrathecal methotrexate administration to minimize the risk of development of CNS disease. A maximum of

Question 78

Gtn Mgx
High risk ds
Ultra high risk ds

Answer 78

High-risk disease management
one-third of high-risk patients
EMA/CO chemotherapy . is myelosuppressive and most patients require granulocyte colony-stimulatingfactor support each week to maintain treatment intensity and to minimize the risk of neutropenic sepsis. Nausea and vomiting are now rarely a problem with antiemetics that include the 5HT3 receptor antagonists such as ondansetron combined with domperidone.

some patients develop peripheral neuropathy that can be aided by

stopping the vincristine

Ultra-high-risk disease

Ultra-high-risk disease is a new term to try to define those high-risk patients at greatest risk of death. the causes of death in patients with high-risk disease either early or late. The early deaths took place within 4 weeks of admission due to organ failure associated with one or more of the following: fatal haemorrhage, metabolic upset from tumour lysis and very adavanced disease. The late deaths were from multiresistant disease. In addition, some deaths were due to cancers that were in fact non-gestational epithelial malignancies histopathologically mimicking gestational choriocarcinomas.

Factors associated with early or late deaths included: a FIGO score above 12, very advanced lung disease, liver with or without brain metastases, and an interval from the last-known and presumed

causative pregnancy greater than 2.8 years.

chemotherapy comprising low-dose etoposide 100 mg/m2 and cisplatin 20 mg/m2 (EP) given intravenously on days 1 and 2 and

repeated weekly for up to 3weeks until the patient is well enough to tolerate standard-dose therapy.

For patients with brain metastases, the methotrexate dose is

increased to 1 g/m2 in the EMA and intrathecal methotrexate is given with the EP to ensure adequate CNS penetration. We also extend the duration of consolidation therapy in ultra-high-risk patients to 8 weeks.

Question 79

Gtn
Surgery

Answer 79

Surgery

Hysterectomy

1. Hysterectomy may be performed to primarily treat PSTI, ETI, or other chemotherapy-resistant disease.
2. Uncontrollable vaginal or intraabdominal bleeding may necessitate hysterectomy
3. adjuvant hysterectomy decreases the total dose of

chemotherapy needed to achieve clinical remission in low risk GTN.

4. Patients with disease apparently confined to the uterus who do not desire future fertility should be counseled about this option

thoracotomy will have stage III GTN, a preoperative B-hCG level < 1500 mIU I mL, and a solitary lung nodule resistant to chemotherapy

Question 80

Which women should be investigated for GTN after a nonmolar pregnancy?

Answer 80

Any woman who develops persistent vaginal bleeding after a pregnancy event is at risk of having GTN. D

A urine hCG test should be performed in all cases of persistent or

irregular vaginal bleeding lasting more than 8 weeks after a pregnancy event.

Symptoms from metastatic disease, such as dyspnea and hemoptysis, or new onset of seizures or paralysis, can occur very rarely.

Biopsy of secondary deposits in the vagina can cause major haemorrhage and is not recommended.

Question 81

Gtn
Subsequent fertility
CONTRACEPTION

Answer 81

Subsequent fertility

fertility is not clearly affected by single agent therapy with methotrexate and apart from hastening the menapause by 3 years.

EMA/CO appears to also have no impact on the chances of a successful pregnancy, which for both methotrexate alone or EMA/CO is 83%.

Further pregnancy should be deferred for 12 months after treatment to avoid any teratogenic effects on developing oocytes and to

minimize possible confusion from the rising hCG levels between a new pregnancy and disease relapse.

CONTRACEPTION

COC use decreases the likelihood of pregnancy compared with less

effective barrier contraception and does not increase the risk of GTN .

Injectable medroxyprogesterone acetate is particularly useful when poor compliance is anticipated.

In contrast, intrauterine devices are not inserted until the B-hCG level is undetectable because of the risk of uterine perforation if an invasive mole is present.
