The most probable reason for umbilical cord prolapse is artificial rupture of membranes. Factors such as cephalic presentation, nulliparity, and prolonged pregnancy decrease the chances of cord prolapse. Prostaglandins do not significantly affect the risk of cord prolapse.

Understanding Umbilical Cord Prolapse

Umbilical cord prolapse is a rare but serious complication that can occur during delivery. It happens when the umbilical cord descends ahead of the presenting part of the fetus, which can lead to compression or spasm of the cord. This can cause fetal hypoxia and potentially irreversible damage or death. Certain factors increase the risk of cord prolapse, such as prematurity, multiparity, polyhydramnios, twin pregnancy, cephalopelvic disproportion, and abnormal presentations like breech or transverse lie.

Around half of all cord prolapses occur when the membranes are artificially ruptured. Diagnosis is usually made when the fetal heart rate becomes abnormal and the cord is palpable vaginally or visible beyond the introitus. Cord prolapse is an obstetric emergency that requires immediate management. The presenting part of the fetus may be pushed back into the uterus to avoid compression, and the cord should be kept warm and moist to prevent vasospasm. The patient may be asked to go on all fours or assume the left lateral position until preparations for an immediate caesarian section have been carried out. Tocolytics may be used to reduce uterine contractions, and retrofilling the bladder with saline can help elevate the presenting part. Although caesarian section is the usual first-line method of delivery, an instrumental vaginal delivery may be possible if the cervix is fully dilated and the head is low.

In conclusion, umbilical cord prolapse is a rare but serious complication that requires prompt recognition and management. Understanding the risk factors and appropriate interventions can help reduce the incidence of fetal mortality associated with this condition.

Based on the presented symptoms, the most probable diagnosis is acute fatty liver of pregnancy. This is supported by the presence of jaundice, mild fever, elevated liver function tests, increased white blood cell count, coagulopathy, and steatosis on imaging. Acute fatty liver of pregnancy typically presents with non-specific symptoms such as fatigue, malaise, and nausea, whereas cholestasis of pregnancy is characterized by severe itching. The absence of abnormalities in hemoglobin, platelet count, and viral screening makes the diagnosis of HELLP syndrome or viral hepatitis unlikely. Additionally, pre-eclampsia is characterized by hypertension and proteinuria. It is important to note that placental ALP can cause an increase in serum ALP levels during pregnancy.

Liver Complications During Pregnancy

During pregnancy, there are several liver complications that may arise. One of the most common is intrahepatic cholestasis of pregnancy, which occurs in about 1% of pregnancies and is typically seen in the third trimester. Symptoms include intense itching, especially in the palms and soles, as well as elevated bilirubin levels. Treatment involves the use of ursodeoxycholic acid for relief and weekly liver function tests. Women with this condition are usually induced at 37 weeks to prevent stillbirth, although maternal morbidity is not typically increased.

Another rare complication is acute fatty liver of pregnancy, which may occur in the third trimester or immediately after delivery. Symptoms include abdominal pain, nausea and vomiting, headache, jaundice, and hypoglycemia. Severe cases may result in pre-eclampsia. ALT levels are typically elevated, and support care is the primary management until delivery can be performed once the patient is stabilized.

Finally, conditions such as Gilbert’s and Dubin-Johnson syndrome may be exacerbated during pregnancy. Additionally, HELLP syndrome, which stands for haemolysis, elevated liver enzymes, and low platelets, is a serious complication that can occur in the third trimester and requires immediate medical attention. Overall, it is important for pregnant women to be aware of these potential liver complications and to seek medical attention if any symptoms arise.

VBAC is not recommended for patients who have had previous vertical (classical) caesarean scars, experienced uterine rupture in the past, or have other contraindications to vaginal birth such as placenta praevia. However, women who have had two or more previous caesarean sections may still be considered for VBAC. The remaining options in this question do not necessarily rule out VBAC.

Caesarean Section: Types, Indications, and Risks

Caesarean section, also known as C-section, is a surgical procedure that involves delivering a baby through an incision in the mother’s abdomen and uterus. In recent years, the rate of C-section has increased significantly due to an increased fear of litigation. There are two main types of C-section: lower segment C-section, which comprises 99% of cases, and classic C-section, which involves a longitudinal incision in the upper segment of the uterus.

C-section may be indicated for various reasons, including absolute cephalopelvic disproportion, placenta praevia grades 3/4, pre-eclampsia, post-maturity, IUGR, fetal distress in labor/prolapsed cord, failure of labor to progress, malpresentations, placental abruption, vaginal infection, and cervical cancer. The urgency of C-section may be categorized into four categories, with Category 1 being the most urgent and Category 4 being elective.

It is important for clinicians to inform women of the serious and frequent risks associated with C-section, including emergency hysterectomy, need for further surgery, admission to intensive care unit, thromboembolic disease, bladder injury, ureteric injury, and death. C-section may also increase the risk of uterine rupture, antepartum stillbirth, placenta praevia, and placenta accreta in subsequent pregnancies. Other complications may include persistent wound and abdominal discomfort, increased risk of repeat C-section, readmission to hospital, haemorrhage, infection, and fetal lacerations.

Vaginal birth after C-section (VBAC) may be an appropriate method of delivery for pregnant women with a single previous C-section delivery, except for those with previous uterine rupture or classical C-section scar. The success rate of VBAC is around 70-75%.

The Sites of Haematopoiesis in the Fetus and Adult

Haematopoiesis, the process of blood cell formation, occurs in various sites throughout fetal development and in adults. The dominant site of haematopoiesis changes as the fetus develops and bones are formed. Here are the different sites of haematopoiesis and their significance:

Bone Marrow: From four months into childhood and adulthood, bone marrow becomes the primary source of hematopoiesis. Red blood cells and immune effector cells are derived from pluripotent haematopoietic cells, which are first noted in blood islands of the yolk sac. By 20 weeks, almost all of these cells are produced by the bone marrow.

Yolk Sac: Haematopoiesis begins in the yolk sac and in angiogenic cell clusters throughout the embryonic body. This involves the formation of nucleated red blood cells, which differentiate from endothelial cells in the walls of blood vessels. Yolk sac haematopoiesis peaks at about one month and becomes insignificant by three months.

Liver: By the sixth week, the fetal liver performs haematopoiesis. This peaks at 12-16 weeks and continues until approximately 36 weeks. Haematopoietic stem cells differentiate in the walls of liver sinusoids. In adults, there is a reserve haematopoietic capacity, especially in the liver.

Spleen: The spleen is a minor site of haematopoiesis, being active between the third and sixth months.

Lymph Nodes: Lymph nodes are not a significant site of haematopoiesis.

In patients with certain conditions, such as haemolytic anaemia or myeloproliferative disease, hepatic haematopoiesis may be reactivated, leading to hepatomegaly. Understanding the different sites of haematopoiesis is important for understanding blood cell formation and certain medical conditions.

A snowstorm appearance on ultrasound scan is indicative of a complete hydatidiform mole, which occurs when all genetic material comes from the father and no foetal parts are present. Vaginal bleeding is often the first symptom. In contrast, an incomplete hydatidiform mole results from two sets of paternal chromosomes and one set of maternal chromosomes, and may have foetal parts present without a snowstorm appearance on ultrasound. Gestational diabetes can cause foetal structural abnormalities and macrosomia, but not a snowstorm appearance on ultrasound. An incomplete miscarriage may cause vaginal bleeding, but it would not result in a snowstorm appearance on ultrasound.

Characteristics of Complete Hydatidiform Mole

A complete hydatidiform mole is a rare type of pregnancy where the fertilized egg develops into a mass of abnormal cells instead of a fetus. This condition is characterized by several features, including vaginal bleeding, an enlarged uterus size that is greater than expected for gestational age, and abnormally high levels of serum hCG. Additionally, an ultrasound may reveal a snowstorm appearance of mixed echogenicity.

In simpler terms, a complete hydatidiform mole is a type of pregnancy that does not develop normally and can cause abnormal bleeding and an enlarged uterus. Doctors can detect this condition through blood tests and ultrasounds, which show a unique appearance of mixed echogenicity. It is important for women to seek medical attention if they experience any abnormal symptoms during pregnancy.

The Edinburgh Scale is a useful tool for screening postnatal depression. The fact that the husband is bringing his wife to the GP practice a month after giving birth suggests that her mood change is not due to baby blues, which typically resolve within three days of giving birth. It is more likely that she is suffering from postnatal depression, but it is important to assess her correctly before offering any treatment such as ECT. The Edinburgh depression scale can be used to assess the patient, with a score greater than 10 indicating possible depression. If there is no immediate harm to the mother or baby, watchful waiting is usually the first step in managing this condition. There is no indication in this question that the mother is experiencing domestic abuse.

Understanding Postpartum Mental Health Problems

Postpartum mental health problems can range from mild ‘baby-blues’ to severe puerperal psychosis. To screen for depression, healthcare professionals may use the Edinburgh Postnatal Depression Scale, which is a 10-item questionnaire that indicates how the mother has felt over the previous week. A score of more than 13 indicates a ‘depressive illness of varying severity’, with sensitivity and specificity of more than 90%. The questionnaire also includes a question about self-harm.

‘Baby-blues’ is seen in around 60-70% of women and typically occurs 3-7 days following birth. It is more common in primips, and mothers are characteristically anxious, tearful, and irritable. Reassurance and support from healthcare professionals, particularly health visitors, play a key role in managing this condition. Most women with the baby blues will not require specific treatment other than reassurance.

Postnatal depression affects around 10% of women, with most cases starting within a month and typically peaking at 3 months. The features are similar to depression seen in other circumstances, and cognitive behavioural therapy may be beneficial. Certain SSRIs such as sertraline and paroxetine may be used if symptoms are severe. Although these medications are secreted in breast milk, they are not thought to be harmful to the infant.

Puerperal psychosis affects approximately 0.2% of women and requires admission to hospital, ideally in a Mother & Baby Unit. Onset usually occurs within the first 2-3 weeks following birth, and features include severe swings in mood (similar to bipolar disorder) and disordered perception (e.g. auditory hallucinations). There is around a 25-50% risk of recurrence following future pregnancies. Paroxetine is recommended by SIGN because of the low milk/plasma ratio, while fluoxetine is best avoided due to a long half-life.

NICE updated guidelines on antenatal care in 2021, recommending the combined test for screening for Down’s syndrome between 11-13+6 weeks. The test includes nuchal translucency measurement, serum B-HCG, and pregnancy-associated plasma protein A (PAPP-A). The quadruple test is offered between 15-20 weeks for women who book later in pregnancy. Results are interpreted as either a ‘lower chance’ or ‘higher chance’ of chromosomal abnormalities. If a woman receives a ‘higher chance’ result, she may be offered a non-invasive prenatal screening test (NIPT) or a diagnostic test. NIPT analyzes cell-free fetal DNA in the mother’s blood and has high sensitivity and specificity for detecting chromosomal abnormalities. Private companies offer NIPT screening from 10 weeks gestation.

Placenta praevia is a pregnancy complication characterized by the attachment of the placenta to the lower part of the uterus. The main symptom is painless bleeding occurring after the 24th week of gestation. Risk factors include a history of placenta praevia, previous caesarean section, damage to the endometrium, and multiple pregnancies. Placenta praevia frequently results in a high presenting part or abnormal lie due to the placenta’s low position.

Understanding Placenta Praevia

Placenta praevia is a condition where the placenta is located wholly or partially in the lower uterine segment. It is a relatively rare condition, with only 5% of women having a low-lying placenta when scanned at 16-20 weeks gestation. However, the incidence at delivery is only 0.5%, as most placentas tend to rise away from the cervix.

There are several factors associated with placenta praevia, including multiparity, multiple pregnancy, and embryos implanting on a lower segment scar from a previous caesarean section. Clinical features of placenta praevia include shock in proportion to visible loss, no pain, a non-tender uterus, abnormal lie and presentation, and a usually normal fetal heart. Coagulation problems are rare, and small bleeds may occur before larger ones.

Diagnosis of placenta praevia should not involve digital vaginal examination before an ultrasound, as this may provoke severe haemorrhage. The condition is often picked up on routine 20-week abdominal ultrasounds, but the Royal College of Obstetricians and Gynaecologists recommends the use of transvaginal ultrasound for improved accuracy and safety. Placenta praevia is classified into four grades, with grade IV being the most severe, where the placenta completely covers the internal os.

In summary, placenta praevia is a rare condition that can have serious consequences if not diagnosed and managed appropriately. It is important for healthcare professionals to be aware of the associated factors and clinical features, and to use appropriate diagnostic methods for accurate grading and management.

Ultrasound in Pregnancy: Nuchal Scan and Hyperechogenic Bowel

During pregnancy, ultrasound is a common diagnostic tool used to monitor the health and development of the fetus. One type of ultrasound is the nuchal scan, which is typically performed between 11 and 13 weeks of gestation. This scan measures the thickness of the nuchal translucency, or the fluid-filled space at the back of the fetus’s neck. An increased nuchal translucency can be a sign of certain conditions, including Down’s syndrome, congenital heart defects, and abdominal wall defects.

Another ultrasound finding that may indicate a potential health issue is hyperechogenic bowel. This refers to an area of the fetus’s bowel that appears brighter than usual on the ultrasound image. Possible causes of hyperechogenic bowel include cystic fibrosis, Down’s syndrome, and cytomegalovirus infection.

It is important to note that these ultrasound findings do not necessarily mean that the fetus has a health problem. Further testing and evaluation may be needed to confirm a diagnosis and determine the best course of action. Ultrasound is just one tool that healthcare providers use to monitor fetal health and ensure the best possible outcome for both mother and baby.

Peripartum Complications: Sheehan’s Syndrome, Eclampsia, and Other Causes of Headache and Visual Disturbances

Peripartum complications can present with a variety of symptoms, including headache and visual disturbances. Sheehan’s syndrome is a condition that results from pituitary infarction due to haemorrhagic shock during labour and the peripartum period. It typically affects the anterior pituitary, leading to hormonal deficiencies that may present acutely or more indolently. Hormone replacement is the mainstay of treatment.

Eclampsia is another peripartum complication that can cause high blood pressure and seizures, sometimes leading to loss of consciousness. It requires urgent medical attention.

Other causes of headache and visual disturbances in the peripartum period include subarachnoid haemorrhage, which may present with sudden onset headache and visual disturbances, and extradural haemorrhage, which is typically found in trauma adjacent to fractures of the temporal bone. Occipital haemorrhagic infarction can also cause these symptoms, but a visual field defect is more suggestive of Sheehan’s syndrome.

It is important for healthcare providers to be aware of these potential complications and to promptly evaluate and manage them to ensure the best possible outcomes for both mother and baby.

Shoulder dystocia is more likely to occur in women with diabetes mellitus. However, using forceps during delivery to pull the baby out can increase the risk of injury to the baby and cause brachial plexus injury. Therefore, it is important to consider alternative delivery methods before resorting to forceps.

Shoulder dystocia is a complication that can occur during vaginal delivery when the body of the fetus cannot be delivered after the head has already been delivered. This is usually due to the anterior shoulder of the fetus becoming stuck on the mother’s pubic bone. Shoulder dystocia can cause harm to both the mother and the fetus. Risk factors for shoulder dystocia include fetal macrosomia, high maternal body mass index, diabetes mellitus, and prolonged labor.

If shoulder dystocia is identified, it is important to call for senior help immediately. The McRoberts’ maneuver is often performed, which involves flexing and abducting the mother’s hips to increase the angle of the pelvis and facilitate delivery. An episiotomy may be performed to provide better access for internal maneuvers, but it will not relieve the bony obstruction. Symphysiotomy and the Zavanelli maneuver are not recommended as they can cause significant maternal morbidity. Oxytocin administration is not indicated for shoulder dystocia.

Complications of shoulder dystocia can include postpartum hemorrhage and perineal tears for the mother, and brachial plexus injury and neonatal death for the fetus. It is important to manage shoulder dystocia promptly and appropriately to minimize the risk of these complications.

The risk of hyperemesis gravidarum is higher in women who are pregnant with twins. This is because each twin produces hCG, which can increase the levels of hCG in the body and lead to hyperemesis gravidarum. Hypothyroidism is not a risk factor, but hyperthyroidism is because it can increase levels of TSH, which is chemically similar to hCG. Age and previous pregnancies do not increase the risk of hyperemesis gravidarum, but a history of hyperemesis gravidarum in a previous pregnancy can increase the likelihood of developing it in future pregnancies.

Hyperemesis gravidarum is an extreme form of nausea and vomiting of pregnancy that occurs in around 1% of pregnancies and is most common between 8 and 12 weeks. It is associated with raised beta hCG levels and can be caused by multiple pregnancies, trophoblastic disease, hyperthyroidism, nulliparity, and obesity. Referral criteria for nausea and vomiting in pregnancy include continued symptoms with ketonuria and/or weight loss, a confirmed or suspected comorbidity, and inability to keep down liquids or oral antiemetics. The diagnosis of hyperemesis gravidarum requires the presence of 5% pre-pregnancy weight loss, dehydration, and electrolyte imbalance. Management includes first-line use of antihistamines and oral cyclizine or promethazine, with second-line options of ondansetron and metoclopramide. Admission may be needed for IV hydration. Complications can include Wernicke’s encephalopathy, Mallory-Weiss tear, central pontine myelinolysis, acute tubular necrosis, and fetal growth issues.

The correct result for the quadruple test screening for Edward’s syndrome is ↓ AFP ↓ oestriol ↓ hCG ↔ inhibin A. This test is offered to pregnant women between 15-20 weeks gestation and measures alpha fetoprotein, unconjugated oestriol, hCG, and inhibin A levels. A ‘high chance’ result would require further screening or diagnostic tests to determine if the baby is affected by Edward’s syndrome. The incorrect answers include a result indicating a higher chance of Down’s syndrome (↑ hCG, ↓ PAPP-A, thickened nuchal translucency), neural tube defects (↑AFP ↔ oestriol ↔ hCG ↔ inhibin A), and a higher chance of Down’s syndrome (↓ AFP ↓ oestriol ↑ hCG ↑ inhibin A). It is important to note that the combined test for Down’s syndrome should not be given to women outside of the appropriate gestation bracket.

NICE updated guidelines on antenatal care in 2021, recommending the combined test for screening for Down’s syndrome between 11-13+6 weeks. The test includes nuchal translucency measurement, serum B-HCG, and pregnancy-associated plasma protein A (PAPP-A). The quadruple test is offered between 15-20 weeks for women who book later in pregnancy. Results are interpreted as either a ‘lower chance’ or ‘higher chance’ of chromosomal abnormalities. If a woman receives a ‘higher chance’ result, she may be offered a non-invasive prenatal screening test (NIPT) or a diagnostic test. NIPT analyzes cell-free fetal DNA in the mother’s blood and has high sensitivity and specificity for detecting chromosomal abnormalities. Private companies offer NIPT screening from 10 weeks gestation.

According to NICE guidelines, the preferred treatment for post-natal depression in breastfeeding women is either sertraline or paroxetine. Before starting treatment, it is recommended to seek advice from a specialist perinatal mental health team. Although tricyclic antidepressants like amitriptyline are an option, they are less commonly used due to concerns about maternal toxicity. Citalopram is also not the first-line choice. It is safe for the patient to take medication while breastfeeding, but the infant should be monitored for any adverse effects. The priority is to manage the patient’s mood symptoms to reduce the risk to both her and her baby.

Understanding Postpartum Mental Health Problems

Postpartum mental health problems can range from mild ‘baby-blues’ to severe puerperal psychosis. To screen for depression, healthcare professionals may use the Edinburgh Postnatal Depression Scale, which is a 10-item questionnaire that indicates how the mother has felt over the previous week.

Guidelines for Managing Diabetes in Pregnancy

Managing diabetes in pregnancy requires close monitoring to reduce the risk of maternal and fetal complications. The National Institute for Health and Care Excellence (NICE) has provided guidelines for healthcare professionals to follow when caring for women with diabetes during pregnancy.

Joint Diabetes and Antenatal Clinic Visits

Women with diabetes should be seen in a Joint Diabetes and Antenatal Clinic every one to two weeks throughout their pregnancy. This ensures that any problems are addressed promptly and appropriately.

Serial Fetal Scanning

Women with diabetes should be offered serial fetal scanning from 26 weeks’ gestation every four weeks. This helps to monitor and prevent complications such as macrosomia, polyhydramnios, stillbirth, and congenital anomalies.

Delivery by Induction of Labour or Caesarean Section

Women with diabetes should be advised to deliver by induction of labour or Caesarean section between 38 and 39+6 weeks’ gestation. This is because diabetes is associated with an increased risk of stillbirth, and the risk is managed by inducing labour when the pregnancy reaches term.

Induction at 41+6 Weeks’ Gestation

Women with diabetes who do not opt for an elective induction or a Caesarean section between 37+0 to 38+6 weeks’ gestation and wish to await spontaneous labour should be warned of the risks of stillbirth and neonatal complications. In cases of prolonged pregnancy, the patient should be offered induction by, at most, 40+6 weeks’ gestation.

Retinal Assessment

All women with pre-existing diabetes should be offered retinal assessment at 16–20 weeks’ gestation. If initial screening is normal, then they are offered a second retinal screening test at 28 weeks’ gestation. If the booking retinal screening is abnormal, then a repeat retinal screening test is offered to these women earlier than 28 weeks, usually between 16 and 20 weeks’ gestation.

Management of Abnormal Alkaline Phosphatase in Pregnancy

Alkaline phosphatase is an enzyme produced by the placenta during pregnancy. If a pregnant patient presents with elevated levels of alkaline phosphatase, it can be concerning. However, in the absence of other abnormal blood results and symptoms, further work-up is not indicated. The most appropriate management in this situation is to reassure the patient and follow up in one week.

It is important to note that dehydration and severe electrolyte abnormalities can cause elevated alkaline phosphatase levels. However, if there is no evidence of these issues, there is no need for admission for intravenous hydration.

Additionally, an urgent ultrasound of the liver is not necessary if the rest of the liver enzymes are normal. Induction of labor is not indicated in this situation either.

If the patient has cholestasis of pregnancy, cholestyramine may be used to bind bile acids. However, if the patient has normal bile acids and no evidence of cholestasis, cholestyramine is not necessary.

The appropriate course of action for a woman exhibiting symptoms of agitation and paranoid delusions after giving birth is to admit her to the hospital for urgent assessment. This is likely a case of postpartum psychosis, which is different from postnatal depression. Postpartum psychosis can include mania, depression, irritability, rapid mood changes, confusion, paranoia, delusions, and/or hallucinations. Prescribing medication to aid in sleep is not appropriate in this case, and reassurance that her low mood will improve with time is also not appropriate due to the risk to herself and her baby. Gradual titration of fluoxetine would not manage her acute symptoms and would not ensure the safety of her or her baby. Ideally, she should be hospitalized in a Mother & Baby Unit.

Understanding Postpartum Mental Health Problems

Postpartum mental health problems can range from mild ‘baby-blues’ to severe puerperal psychosis. To screen for depression, healthcare professionals may use the Edinburgh Postnatal Depression Scale, which is a 10-item questionnaire that indicates how the mother has felt over the previous week. A score of more than 13 indicates a ‘depressive illness of varying severity’, with sensitivity and specificity of more than 90%. The questionnaire also includes a question about self-harm.

There is around a 25-50% risk of recurrence following future pregnancies. Paroxetine is recommended by SIGN because of the low milk/plasma ratio, while fluoxetine is best avoided due to a long half-life.

Intrahepatic cholestasis of pregnancy is known to increase the risk of stillbirth, which is why doctors usually recommend inducing labor at 37-38 weeks of gestation. Although some studies suggest that this may no longer be the case, the general consensus is that the risk of stillbirth is still relatively high. Therefore, early induction of labor is still advised.

While advanced maternal age is a risk factor for stillbirth, being 34 years old is not considered to be in the category of older maternal age, which is defined as 35 years old or older.

Although there may be a genetic component to stillbirths, having a step-sister with a history of stillbirth does not constitute a family history of the condition. This is because step-siblings are not biologically related, but rather connected through marriage.

Lamotrigine is considered the safest anti-epileptic medication to use during pregnancy, and there is no evidence to suggest that it increases the risk of stillbirth.

Intrahepatic Cholestasis of Pregnancy: Symptoms and Management

Intrahepatic cholestasis of pregnancy, also known as obstetric cholestasis, is a condition that affects approximately 1% of pregnancies in the UK. It is characterized by intense itching, particularly on the palms, soles, and abdomen, and may also result in clinically detectable jaundice in around 20% of patients. Raised bilirubin levels are seen in over 90% of cases.

The management of intrahepatic cholestasis of pregnancy typically involves induction of labor at 37-38 weeks, although this practice may not be evidence-based. Ursodeoxycholic acid is also widely used, although the evidence base for its effectiveness is not clear. Additionally, vitamin K supplementation may be recommended.

It is important to note that the recurrence rate of intrahepatic cholestasis of pregnancy in subsequent pregnancies is high, ranging from 45-90%. Therefore, close monitoring and management are necessary for women who have experienced this condition in the past.

The recommended medical management for a miscarriage is the administration of vaginal misoprostol, as stated in the 2018 NICE guidelines. This is particularly suitable for patients with a medical history of coagulopathy, such as Von Willebrand disease, as it is a safer option than expectant management. Oral methotrexate is not appropriate for a miscarriage, as it is used for the medical management of ectopic pregnancies. Salpingectomy is a surgical procedure used for tubular ectopic pregnancies, but not for miscarriages. Vacuum aspiration is a surgical option for miscarriages, but medical management is preferred as it is safer and allows the patient to have more control over the process.

Management Options for Miscarriage

Miscarriage can be a difficult and emotional experience for women. In the 2019 NICE guidelines, three types of management for miscarriage were discussed: expectant, medical, and surgical. Expectant management involves waiting for a spontaneous miscarriage and is considered the first-line option. However, if it is unsuccessful, medical or surgical management may be offered.

Medical management involves using tablets to expedite the miscarriage. Vaginal misoprostol, a prostaglandin analogue, is used to cause strong myometrial contractions leading to the expulsion of tissue. It is important to advise patients to contact their doctor if bleeding does not start within 24 hours. Antiemetics and pain relief should also be given.

Surgical management involves undergoing a surgical procedure under local or general anaesthetic. The two main options are vacuum aspiration (suction curettage) or surgical management in theatre. Vacuum aspiration is done under local anaesthetic as an outpatient, while surgical management is done in theatre under general anaesthetic. This was previously referred to as ‘Evacuation of retained products of conception’.

It is important to note that some situations are better managed with medical or surgical management, such as an increased risk of haemorrhage, being in the late first trimester, having coagulopathies or being unable to have a blood transfusion, previous adverse and/or traumatic experience associated with pregnancy, evidence of infection, and more. Ultimately, the management option chosen should be based on the individual patient’s needs and preferences.

Gestational diabetes is a common medical disorder affecting around 4% of pregnancies. Risk factors include a high BMI, previous gestational diabetes, and family history of diabetes. Screening is done through an oral glucose tolerance test, and diagnostic thresholds have recently been updated. Management includes self-monitoring of blood glucose, diet and exercise advice, and medication if necessary. For pre-existing diabetes, weight loss and insulin are recommended, and tight glycemic control is important. Targets for self-monitoring include fasting glucose of 5.3 mmol/l and 1-2 hour post-meal glucose levels.
