A 30 year old women who is 24 weeks pregnant attends EPU due to suprapubic pain. Ultrasound shows a viable foetus and also a fibroid with a cystic fluid filled centre. What is the likely diagnosis?
Your Answer: Red degeneration of fibroid
Explanation:Red degeneration of fibroids is one of 4 methods of fibroid degeneration. Although uncommon outside pregnancy it is thought to be the most common form of fibroid degeneration during pregnancy and typically occurs in the 2nd trimester. It is thought to arise from the fibroid outgrowing its blood supply and haemorrhagic infarction occurs. Ultrasound will typically show a localised fluid collection (blood) within the fibroid.

Stages of labour
Your Answer: The third stage ends with the delivery of the placenta and membranes
Explanation:First stage: The latent phase is generally defined as beginning at the point at which the woman perceives regular uterine contractions. A definition of active labour in a British journal was having contractions more frequent than every 5 minutes, in addition to either a cervical dilation of 3 cm or more or a cervical effacement of 80% or more.
Second stage: fetal expulsion begins when the cervix is fully dilated, and ends when the baby is born.
Third stage: placenta delivery – The period from just after the foetus is expelled until just after the placenta is expelled is called the third stage of labour or the involution stage.

Which of the following hormones inhibits lactogenesis during pregnancy?
Your Answer: Oestrogen and Progesterone
Explanation:Under the influence of prolactin, oestrogen and progesterone and human placental lactogen (hPL), the mammary epithelium proliferates but remains presecretory during mammogenesis. Lactogenesis is inhibited by high circulating levels of progesterone and oestrogen which block cortisol binding sites. Cortisol would have otherwise have worked synergistically with prolactin in milk production. A sharp decrease in progesterone levels after delivery allows prolactin and oxytocin to stimulate milk production and the milk ejection reflex in response to suckling. Prolactin continues to maintain milk production in galactopoiesis.

The midwife asks for your advice about a 33 year old woman who she has just seen at her booking appointment. The patient had an uncomplicated pregnancy 10 years ago. This is her second pregnancy. There is no significant personal or family history. On examination the patients blood pressure is 120/75, BMI 32.5kg/m2. The midwife asks your advice on testing for gestational diabetes. What would you advise?
Your Answer: OGTT at 24-28 weeks
Explanation:Gestational diabetes (GDM) occurs in 2–9 per cent of all pregnancies. Screening for diabetes in pregnancy can be justify ed to diagnose previously unrecognized cases of pre-existing diabetes and to identify a group of women who are at risk of developing NIDDM later in life. No single screening test has been shown to be perfect in terms of high sensitivity and specific city for gestational diabetes. Urinary glucose is unreliable, and most screening tests now rely on blood glucose estimation, with an oral glucose tolerance test commonly used. The aim of glucose control is to keep fasting levels between 3.5 and 5.5 mmol/L and postprandial levels 7.1 mmol/L, with insulin treatment usually indicated outside these ranges.

A 30 year old women who is 24 weeks pregnant attends clinic due to suprapubic pain. Ultrasound shows a viable foetus and also a fibroid with a cystic fluid filled centre. What is the likely diagnosis?
Your Answer: Red degeneration of fibroid
Correct Answer: Cystic degeneration of fibroid
Explanation:A fibroid is a benign tumour of the smooth muscles of the uterus also known as a leiomyoma. It has a typical whorled appearance and this may be altered following degeneration which occurs in four main types:
1. Red degeneration, also known as carneous degeneration, of degeneration that can involve a uterine leiomyoma. While it is an uncommon type of degeneration, it is thought to be the most common form of degeneration of a leiomyoma during pregnancy. Red degeneration follows an acute disruption of the blood supply to the fibroid during growth typically in a mid-second trimester presenting as sudden onset of pain with tenderness localizing to the area of the uterus along with pyrexia and leucocytosis. On ultrasound it can have peripheral (rim).2. Hyaline degeneration is the most common form of degeneration that can occur in a uterine leiomyoma. It is thought to occur in up to 60% of uterine leiomyomasoccurs when the fibroid outgrows its blood supply. this may progresses to central necrosis leaving a cystic space in the centre knowns as cystic degeneration.
3. Cystic degeneration is an uncommon type of degeneration that a uterine leiomyoma (fibroid) can undergo. This type of degeneration is thought to represent ,4% of all types of uterine leiomyoma degeneration. When the leiomyoma increases in size, the vascular supply to it becomes inadequate and leads to different types of degeneration: hyaline, cystic, myxoid, or red degeneration. Dystrophic calcification may also occur. Hyalinization is the commonest type of degeneration. Cystic degeneration is an extreme sequel of edema. Ultrasound may show a hypoechoic or heterogeneous uterine mass with cystic areas.
4. Myxoid degeneration of leiomyoma is one of the rarer types of degeneration that can occur in a uterine leiomyoma. While this type of degeneration is generally considered rare, the highest prevalence for this type of degeneration has been reported as up to 50% of all degenerations of leiomyomas. Fibroids (i.e. uterine leiomyomas) that have undergone myxoid degeneration are filled with a gelatinous material and can be difficult to differentiate from cystic degeneration; however, they typically appear as more complex cystic masses. They appear hypocellular with a myxoid matrix.

What is the mode of action of Tranexamic acid?
Your Answer: Inhibits Plasminogen Activation
Explanation:Tranexamic acid is an antifibrinolytic drug which is one of the treatment options in menorrhagia i.e. heavy menstrual bleeding. It acts by binding to the receptor sites on plasminogen thus preventing plasmin from attaching to those receptors thus inhibiting plasminogen activation.
If pharmaceutical treatment is appropriate NICE advise treatments should be considered in the following order:
1. levonorgestrel-releasing intrauterine system (LNG-IUS) provided at least 12 months use is anticipated
2. tranexamic acid or NSAIDs* or combined oral contraceptives (COCs) or cyclical oral progestogens
3. Consider progesterone only contraception e.g. injected long-acting progestogens*When heavy menstrual bleeding (HMB) coexists with dysmenorrhoea NSAIDs should be preferred to tranexamic acid. Also note NSAIDs and tranexamic are appropriate to use if treatment needed pending investigations.

An HIV positive woman who is 18 weeks pregnant complains of frothy yellow vaginal discharge and vaginal soreness. A wet mount and microscopy confirms a Trichomonas vaginalis infection. Which of the following is the most appropriate treatment regime?
Your Answer: Metronidazole 2g orally single dose
Correct Answer: Metronidazole 500mg BD 7 days
Explanation:Trichomoniasis is considered a sexually transmitted infection found both in men and women caused by the flagellate protozoan Trichomonas vaginalis. The organism is mainly found in the vagina and the urethra. Though many infected women can be asymptomatic, they can also present with yellow frothy vaginal discharge, itching and vaginitis, dysuria or an offensive odour. For the diagnosis of t. vaginalis in women, a swab is taken from the posterior fornix during speculum examination and the flagellates are detected under light-field microscopy. The recommended treatment for t. vaginalis for a HIV positive woman who is pregnant is 500mg of metronidazole twice daily for 7 days. High dose metronidazole as a 2g single dose tablet is not advised during pregnancy. All sexual partners should also be treated, and screening for other STIs should be carried out.

A 67 year old patient with endometrial carcinoma is to undergo staging investigations. There is evidence of invasion into the vaginal wall, but the lymph nodes are spared, and there is no distant metastasis. According to FIGO, what stage is this?
Your Answer: 2
Correct Answer: 3B
Explanation:Endometrial cancer is one of the most common gynaecological malignancies present in postmenopausal women, with a peak incidence between the ages of 60-89. Factors associated with endometrial cancer include obesity, hypertension and diabetes. Full staging for endometrial cancer is surgical, including several other radiologic investigations. According to FIGO staging classifications:
Stage 1 indicates a tumour confined to the uterine body
Stage 2 indicates the invasion of the cervical stroma
Stage 3 indicates local and regional spread, where the tumour invades the serosa in stage 3A, spreads to the vagina and parametrium in stage 3B, and metastasizes to the pelvic or para-aortic lymph nodes in stage 3C.
Stage 4 indicates tumour invasion on the bladder or bowel mucosa, or distant metastasis. -

In a patient who undergoes a medical abortion at 10 weeks gestation, what advice would you give regarding Rhesus Anti-D Immunoglobulin?
Your Answer: All RhD-negative women who are not alloimmunized should receive Anti-D IgG
Explanation:The Rhesus status of a mother is important in pregnancy and abortion. The exposure of an Rh-negative mother to Rh antigens from a positive foetus, will influence the development of anti-Rh antibodies. This may cause problems in subsequent pregnancies leading to haemolysis in the newborn. Rh Anti RhD- globulin is therefore given to non-sensitised Rh-negative mothers to prevent the formation of anti-Rh antibodies within 72 hours following abortion. Anti RhD globulin is not useful for already sensitized, or RhD positive mothers.

Which of the following statements is true regarding management of caesarean section?
Your Answer: Co-amoxiclav 1.2g IV should be given prior to skin incision
Correct Answer: Uterine closure can be in 1 or 2 layers
Explanation:Closure of the uterus should be performed in either single or double layers with continuous or interrupted sutures. The initial suture should be placed just lateral to the incision angle, and the closure continued to a point just lateral to the angle on the opposite side. A running stitch is often employed and this may be locked to improve haemostasis. If a second layer is used, an inverting suture or horizontal suture should overlap the myometrium. Once repaired, the incision is assessed for haemostasis and ‘figure-of-eight’
sutures can be employed to control bleeding. Peritoneal closure is unnecessary. Abdominal closure is performed in the anatomical planes with high strength, low reactivity materials, such as polyglycolic acid or polyglactin. Diamorphine is advised for intra and post op analgesia and oxytocin is advised to reduce blood loss. -

Your Answer: A Hb of less than 10.5g/l should prompt haematinics and exclusion of haemoglobinopathies
Explanation:Anaemia in pregnancy is most frequently caused by iron or folate deficiency, however, a wide variety of other causes may be considered, especially if the haemoglobin value is below 9.0 g/dL. A haemoglobin level of 11 g/dL or more is considered normal early in pregnancy, with the upper limit of the ‘normal range’ dropping to 10.5 g/dL by 28 weeks gestation. Haemoglobin < 10.5 g/dl in the antenatal period, one should exclude haemoglobinopathies and consider haematinic deficiency. Oral iron is 1st line treatment for iron deficiency. Anaemia not due to haematinic deficiency will not respond to any form of iron. This should be managed with transfusion

What type of drug is clavulanic acid?
Your Answer: Beta-lactamase inhibitor
Explanation:Clavulanic acid is a beta-lactamase inhibitor that is most often combined with a penicillin to form Augmentin or Co-amoxiclav for greater antibiotic efficacy. The drug works by irreversibly binding to enzymes present in bacteria which posses the Beta-lactamase enzyme. This enzyme is responsible for inactivating Beta-Lactam antibiotics such as penicillin.

A 24 year old lady is 9 weeks pregnant with her first child. She attends clinic complaining of severe vomiting and is unable to keep fluids down. The most likely diagnosis is hyperemesis gravidarum. Which of the following is the underlying cause?
Your Answer:
Correct Answer: Increased circulating HCG
Explanation:Hyperemesis gravidarum (HG) is a severe form of nausea and vomiting in pregnancy, associated with weight loss of more than 5% of pre-pregnancy weight, dehydration and electrolyte imbalance. HG is usually most severe during the first 12 weeks of pregnancy and is thought to be caused by high circulating levels of HCG.
There is not yet any evidence that pregnancy itself increases the sensitivity of the area postrema, or that the hormones, oestradiol, or progesterone increase vomiting. Generally, higher concentrations of dopamine stimulates receptors in the chemoreceptor trigger zone leading to nausea and vomiting. Although this has not been demonstrated as the cause of hyperemesis gravidarum.

A 19 year old patient on Lamotrigine 125 mg twice a day for the past two years has recently been prescribed Microgynon 30 as a contraceptive before she leaves for Uni. What could the main concern be?
Your Answer:
Correct Answer: Combined contraceptive may reduce Lamotrigine levels and increase seizure risk
Explanation:Lamotrigine, a drug used to treat epilepsy, is less effective when taken with combined oral contraceptives. The oestrogen component of the pill decreases the circulating levels of Lamotrigine, increasing the risk of seizures. The combination is therefore classified as a UKMEC 3, as the risk of the drug combination may outweigh the benefit. As an alternative, the progesterone-only pill, depo progesterone, Mirena or the copper IUD may be considered as there is no restriction on concomitant use. Lamotrigine is not metabolised through cytochrome P450 like other antiepileptic drugs such as carbamazepine and phenytoin, neither is it an enzyme inhibitor.

A 23 year old patient presents to the emergency department with sudden onset of severe lower abdominal and pelvic pain. History reveals she normally has regular 28 day cycles but she missed her last period. Past medical history reveals 2 termination of pregnancy procedures in the past 3 years. The most recent one 6 months ago. She smokes 5 cigarettes per day.
Your Answer:
Correct Answer: Ectopic pregnancy
Explanation:This patient is most likely to have a ruptured ectopic pregnancy. The history of multiple TOPs suggests her contraceptive methods are not reliable and her missed period is suggestive she may currently be pregnant. There is no temperature or vaginal discharge to suggest PID though this is of course possible as is appendicitis. The last termination was 6 months ago so endometritis is unlikely.

A 26 year old patient with a past medical history of 2 terminations of pregnancies over the past 2 years, presents to the emergency centre complaining of severe abdominal pain and some vaginal bleeding. She has a regular 28 day cycle, and is on an oral contraceptive pill, but missed last month's period. Her last termination was over 6 months ago. She smokes almost a pack of cigarettes a day. Which of the following is the most likely diagnosis?
Your Answer:
Correct Answer: Ectopic pregnancy
Explanation:The clinical picture demonstrated is most likely that of a ruptured ectopic pregnancy. The period of amenorrhea may point to pregnancy, while the past medical history of 2 recent terminations of pregnancy may indicate a failure of her current contraceptive method. Smoking cigarettes have been shown to not only decrease the efficacy of OCPs, but also serve as a known risk factor for ectopic pregnancy. The lady is unlikely to have endometritis as her last termination was over 6 months ago. The lack of fever helps to make appendicitis, PID and pyelonephritis less likely, though they are still possible.

A 24 year old lady is rushed to the emergency department complaining of vaginal spotting and abdominal cramping. Her 6 week pregnancy was confirmed by ultrasound scan last week. On speculum examination, the cervical os is open with blood noted around it. Which of the following is the most likely diagnosis?
Your Answer:
Correct Answer: Inevitable Miscarriage
Explanation:A miscarriage is defined as the spontaneous loss of a pregnancy before the age of viability at 24 weeks in the UK. An inevitable miscarriage occurs with the usual symptoms of a miscarriage such as menstrual-like cramping, vaginal bleeding and a dilated cervix. The gestational sac has ruptured but products of conception have not been passed. The products of conception will eventually pass.
A missed miscarriage is described as a loss of pregnancy without vaginal bleeding, loss of tissue, cervical changes or abdominal pain. During a scan, a fetal heartbeat is not observed, and the gestational sac may be small.
A threatened miscarriage is when the cervix dilates and uterine bleeding is seen; the pregnancy could still be viable.
A complete miscarriage occurs when all the products of conception are expelled from the uterus, bleeding has stopped, and the cervix has closed up after dilation. Recurrent miscarriages are described as spontaneous pregnancy loss of more than 2 to 3 consecutive times.

A 36 year old patient is diagnosed with cervical cancer and staging investigations show there is parametrial involvement but it is confined within the pelvic wall and does not involve the lower 1/3 vagina. There is no evidence of hydronephrosis. What FIGO stage is this?
Your Answer:
Correct Answer: 2B
Explanation:It is stage 2B. Stage I: is strictly confined to the cervix; extension to the uterine corpus should be disregarded. The diagnosis of both Stages IA1 and IA2 should be based on microscopic examination of removed tissue, preferably a cone, which must include the entire lesion.
2010 FIGO classification of cervical carcinoma:
Stage IA: Invasive cancer identified only microscopically. Invasion is limited to measured stromal invasion with a maximum depth of 5 mm and no wider than 7 mm.
Stage IA1: Measured invasion of the stroma no greater than 3 mm in depth and no wider than 7 mm diameter.
Stage IA2: Measured invasion of stroma greater than 3 mm but no greater than 5 mm in depth and no wider than 7 mm in diameter.Stage IB: Clinical lesions confined to the cervix or preclinical lesions greater than Stage IA. All gross lesions even with superficial invasion are Stage IB cancers.
Stage IB1: Clinical lesions no greater than 4 cm in size.
Stage IB2: Clinical lesions greater than 4 cm in size.Stage II: carcinoma that extends beyond the cervix, but does not extend into the pelvic wall. The carcinoma involves the vagina, but not as far as the lower third.
Stage IIA: No obvious parametrial involvement. Involvement of up to the upper two-thirds of the vagina.
Stage IIB: Obvious parametrial involvement, but not into the pelvic sidewall.Stage III: carcinoma that has extended into the pelvic sidewall. On rectal examination, there is no cancer-free space between the tumour and the pelvic sidewall. The tumour involves the lower third of the vagina. All cases with hydronephrosis or a non-functioning kidney are Stage III cancers.
Stage IIIA: No extension into the pelvic sidewall but involvement of the lower third of the vagina.
Stage IIIB: Extension into the pelvic sidewall or hydronephrosis or non-functioning kidney.Stage IV: carcinoma that has extended beyond the true pelvis or has clinically involved the mucosa of the bladder and/or rectum.
Stage IVA: Spread of the tumour into adjacent pelvic organs.
Stage IVB: Spread to distant organs. -

The COCP (Combined Oral Contraceptive Pill) causes all of the following biochemical effects EXCEPT which one?
Your Answer:
Correct Answer: Elevate FSH
Explanation:Remember patients with PCOS have elevated LH. COCPs suppress synthesis and secretion of FSH and the mid-cycle surge of LH, thus inhibiting the development of ovarian follicles and ovulation COCPs reduce hyperandrogenism as reduced LH secretion results in decreased ovarian synthesis of androgens. Furthermore they stimulate the liver to produce Sex Hormone Binding Globulin which leads to decreased circulating free androgens. Other mechanisms include reduction in adrenal androgen secretion and inhibition of peripheral conversion of testosterone to dihydrotestosterone and binding of dihydrotestosterone to androgen receptors

Explanation:Lower abdominal pain during menstrual periods and lower back or leg pain are associated with endometriosis in the uterosacral ligaments. Endometriosis can cause diarrhoea and IBS type symptoms. Note Endometriosis on the uterosacral ligament can cause tender nodules to form. These can be palpated during pelvic exam. Tender nodules are specific to endometriosis of the uterosacral ligament so if the question mentions feeling a tender nodule during PV exam think endometriosis of the Uterosacral ligaments!

What percentage of pregnancies will be uncomplicated following a single episode of reduced fetal movements?
Your Answer:
Correct Answer: 70%
Explanation:Reduced fetal movements can be the first indication of possible fetal abnormalities. Movements are first perceived by the mother from about 18-20 weeks gestation, increase in size and frequency until 32 weeks gestation when they plateau at about 31 movements per hour. Investigations for reduced fetal heart rate include auscultation of the fetal heart rate using a handheld doppler device, and a cardiotocograph or ultrasound if the foetus is above 28 weeks gestation. About 70% of women who experience one episode of reduced fetal movement have uncomplicated pregnancies. They are advised to report to a maternal unit if another episode occurs.

You receive a swab result from a patient who had complained of odorous vaginal discharge. It confirms bacterial vaginosis (BV). Which pathogen is most commonly associated with BV?
Your Answer:
Correct Answer: Gardnerella vaginalis
Explanation:Bacterial vaginosis is characterised by a foul smelling vaginal discharge without inflammation. The most common spp to cause this is gardnerella vaginalis. Other spp include mycoplasma hominis and bacteroides. It occurs due to growth and increase in anaerobic spp with simultaneous reduction in lactobacilli in vaginal flora causing an increase in vaginal pH. It is the most common cause of abnormal vaginal discharge in women of childbearing age.

You are asked to review a patient. They have attended for a scan at 13 weeks following a positive pregnancy test. The patient has had 2 previous pregnancies for which she opted for termination on both occasions. The scan shows a large irregular haemorrhagic mass that appears to be invading into the myometrium. What is the likely diagnosis?
Your Answer:
Correct Answer: Choriocarcinoma
Explanation:Choriocarcinoma may arise as a complication of gestation or as spontaneous germ cell tumours. As this scenario depicts that the women has previous abortion points to the fact that these may have been molar pregnancies. As choriocarcinoma can arise from a molar pregnancy it can be differentiated from it by the presence of invasion into the uterus and metastasis to the lungs primarily.

Which of the following regarding the use of tocolytics is true?
Your Answer:
Correct Answer: Use of a tocolytic drug is not associated with a clear reduction in perinatal or neonatal mortality, or neonatal morbidity
Explanation:Tocolytics are used to suppress contractions. The Canadian preterm labour trial which remains a very influential tocolytic trial to date concluded that tocolytics such as a beta agonist have no significant benefit on perinatal mortality or morbidity or prolong pregnancy to term however it did reduce the number of women delivering within 2 days by 40%. This 48 hour window is the only reason for the use of tocolytics.

Which one of the following has the most significant effect on slowing drug metabolism in pregnancy?
Your Answer:
Correct Answer: Progesterone effect on gastric motility
Explanation:Progesterone down regulates gastric motility meaning drugs are absorbed and metabolised more slowly, thus drugs are absorbed, metabolised and cleared more slowly. Most of the drugs are transported after binding to the albumin.
Lower albumin levels mean a greater unbound drug fraction but as this may be thought to increase drug concentrations it actually leaves more available for hepatic clearance or renal excretion so overall drug concentrations are unchanged and metabolism increased.
Increase in hepatic flow will increase the metabolism of the drug as the drug will be transported faster.
Increased renal blood flow will result in the faster clearance of the drug from the body. -

A patient admitted to the medical ward complains of a mild fever and vaginal discharge. Clue cells are seen on microscopy from a vaginal swab. Which of the following infections feature clue cells?
Your Answer:
Correct Answer: Bacterial Vaginosis
Explanation:Bacterial vaginosis (BV) is a common infection of the vagina caused by the overgrowth of atypical bacteria, most commonly Gardnerella vaginalis, a gram-negative rod. In diagnosing BV, a swab is taken for microscopy, often revealing clue cells. Clue cells are cells of the vaginal epithelium which are covered by adherent Gardnerella, giving them a distinctive look under the microscope. Though many are asymptomatic, some infected women complain of a greyish, foul-smelling vaginal discharge. Their vaginal fluid pH may also become more alkaline. BV does not however present with pyrexia, so the lady’s fever could be attributed to another cause as she is still a patient on the medical ward.

A 29 year old patient presents due to the sensation of reduced fetal movements (RFM). From what gestation is CTG assessment of RFM advised?
Your Answer:
Correct Answer: 28+0 weeks
Explanation:The cardiotocograph (CTG) is a continuous tracing of the fetal heart rate used to assess fetal wellbeing. The Doppler effect detects fetal heart motion and allows the interval between successive beats to be measured, thereby allowing a continuous assessment of fetal heart rate. The mother perceives the fetal movement by the 18-20 week of gestation and these increase until the 32 week. A mother should under go CTG if the fetal movements are reduced by the 28 week of gestation.

A 30 year old woman with a history of two previous C section deliveries, is rushed to the hospital for an emergency c-section at 36 weeks gestation due to antenatal haemorrhage. Upon examination of the uterus, the placenta has invaded the myometrium but the serosa is spared. Which of the following identifies this condition?
Your Answer:
Correct Answer: Placenta Increta
Explanation:Abnormal placental adherence to the uterus, generally termed Placenta Accreta, is divided into 3 conditions.
– Placenta accreta: refers to the invasion of the chorionic villi beyond the decidual surface of the myometrium.
– Placenta increta: the villi invade deep into the myometrium but spare the serosa;
– Placenta percreta: the chorionic villi invade through the myometrium, penetrate the uterine serosa, and may invade surrounding pelvic structures.These conditions can predispose patients to obstetric bleeding in the third trimester, often requiring emergency intervention.
Risk factors in the development of an abnormal placental adherence include previous c-sections. Placenta Previa, is also a cause of antepartum haemorrhage and serves as a risk factor in the development of abnormal placental adherence.

What is the most common cause of sepsis in the puerperium?
Your Answer:
Correct Answer: Endometritis
Explanation:Significant puerperal pyrexia is defined as a temperature of 38ºC or higher on any two of the first 10 days postpartum, exclusive of the first 24 hours. A mixed flora normally colonizes the vagina with low virulence. Puerperal infection is usually polymicrobial and involves contaminants from the bowel that colonize the perineum and lower genital tract. Following delivery, natural barriers to infection are temporarily removed and therefore organisms with a pathogenic potential can ascend from the lower genital tract into the uterine cavity. Placental separation exposes a large raw area equivalent to an open wound, and retained products of conception and blood clots within the uterus can provide an excellent culture medium for infection.
