Breastfeeding is generally safe with most anti-epileptic drugs, except for a few exceptions. Lamotrigine is one of the drugs that is considered safe for breastfeeding, but infants should still be monitored for certain symptoms. Aspirin, codeine, and lithium are not recommended for breastfeeding mothers due to potential risks to the infant’s health. Aspirin can cause metabolic acidosis and Reye’s syndrome, while codeine is excreted in breast milk and lithium can cause renal and thyroid dysfunction in neonates.

Pregnancy and breastfeeding can be a concern for women with epilepsy. It is generally recommended that women continue taking their medication during pregnancy, as the risks of uncontrolled seizures outweigh the potential risks to the fetus. However, it is important for women to take folic acid before pregnancy to reduce the risk of neural tube defects. The use of antiepileptic medication during pregnancy can increase the risk of congenital defects, but this risk is still relatively low. It is recommended to aim for monotherapy and there is no need to monitor drug levels. Sodium valproate is associated with neural tube defects, while carbamazepine is considered the least teratogenic of the older antiepileptics. Phenytoin is associated with cleft palate, and lamotrigine may require a dose increase during pregnancy. Breastfeeding is generally safe for mothers taking antiepileptics, except for barbiturates. Pregnant women taking phenytoin should be given vitamin K in the last month of pregnancy to prevent clotting disorders in the newborn.

A warning has been issued about the use of sodium valproate during pregnancy and in women of childbearing age. New evidence suggests a significant risk of neurodevelopmental delay in children following maternal use of this medication. Therefore, it should only be used if clearly necessary and under specialist neurological or psychiatric advice. It is important for women with epilepsy to discuss their options with their healthcare provider and make informed decisions about their treatment during pregnancy and breastfeeding.

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.

If an ectopic pregnancy is larger than 35mm or has a serum B-hCG level exceeding 5,000 IU/L, surgical intervention is necessary. The patient in this scenario is experiencing symptoms such as pain and dizziness, and her tachycardia indicates a risk of instability. While she is currently stable, surgical management should be performed promptly. A laparotomy is not immediately necessary, but the procedure should be carried out as soon as possible. Waiting for a blood hCG is unnecessary, and medical management is not appropriate.

Ectopic pregnancy is a serious condition that requires prompt investigation and management. Women who are stable are typically investigated and managed in an early pregnancy assessment unit, while those who are unstable should be referred to the emergency department. The investigation of choice for ectopic pregnancy is a transvaginal ultrasound, which will confirm the presence of a positive pregnancy test.

There are three ways to manage ectopic pregnancies: expectant management, medical management, and surgical management. The choice of management will depend on various criteria, such as the size of the ectopic pregnancy, whether it is ruptured or not, and the patient’s symptoms and hCG levels. Expectant management involves closely monitoring the patient over 48 hours, while medical management involves giving the patient methotrexate and requires follow-up. Surgical management can involve salpingectomy or salpingostomy, depending on the patient’s risk factors for infertility.

Salpingectomy is the first-line treatment for women without other risk factors for infertility, while salpingostomy should be considered for women with contralateral tube damage. However, around 1 in 5 women who undergo a salpingostomy require further treatment, such as methotrexate and/or a salpingectomy. It is important to carefully consider the patient’s individual circumstances and make a decision that will provide the best possible outcome.

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.

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.

The first stage of labour begins with the onset of true labour and ends when the cervix is fully dilated at 10cm. During this stage, regular contractions occur and the cervix gradually dilates. It is important to note that although 4 cm and 6cm cervical dilation occur during this stage, it does not end until the cervix is fully effaced at 10cm. The second stage of labour ends with the birth of the foetus, not the first.

Labour is divided into three stages, with the first stage beginning from the onset of true labour until the cervix is fully dilated. This stage is further divided into two phases: the latent phase and the active phase. The latent phase involves dilation of the cervix from 0-3 cm and typically lasts around 6 hours. The active phase involves dilation from 3-10 cm and progresses at a rate of approximately 1 cm per hour. In primigravidas, this stage can last between 10-16 hours.

During this stage, the baby’s presentation is important to note. Approximately 90% of babies present in the vertex position, with the head entering the pelvis in an occipito-lateral position. The head typically delivers in an occipito-anterior position.

The patient is experiencing intense pruritus and has elevated bilirubin levels, which are common symptoms of intrahepatic cholestasis of pregnancy. Due to the heightened risk of stillbirth, induction of labor at 37 weeks is typically recommended. While a caesarian section at 37 weeks may be considered, there is insufficient evidence to support this approach over induction. Induction at 34 weeks is not advisable, and reassurance with a normal delivery at term is not appropriate. Therefore, a discussion regarding induction at 37 weeks is necessary.

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 patient’s symptoms suggest an infectious process, as evidenced by her fever, rapid heartbeat, and elevated levels of neutrophils (which are already higher than normal during pregnancy). Chorioamnionitis is a clinical diagnosis that may be indicated by uterine tenderness and a foul-smelling discharge, and the presence of a baseline fetal tachycardia supports this diagnosis. The likely cause of the infection is prolonged premature rupture of membranes. Although the patient has a history of uterine fibroids, this is not relevant to her current condition, as fibroids typically cause symptoms earlier in pregnancy. Acute placental abruption would cause sudden abdominal pain, which is not present in this case. While pyelonephritis is a possible differential diagnosis, the absence of dysuria makes it less likely.

Understanding Chorioamnionitis

Chorioamnionitis is a serious medical condition that can affect both the mother and the foetus during pregnancy. It is caused by a bacterial infection that affects the amniotic fluid, membranes, and placenta. This condition is considered a medical emergency and can be life-threatening if not treated promptly. It is more likely to occur when the membranes rupture prematurely, but it can also happen when the membranes are still intact.

Prompt delivery of the foetus is crucial in treating chorioamnionitis, and a cesarean section may be necessary. Intravenous antibiotics are also administered to help fight the infection. This condition affects up to 5% of all pregnancies, and it is important for pregnant women to be aware of the symptoms and seek medical attention immediately if they suspect they may have chorioamnionitis.

During pregnancy, hormonal changes can lead to increased blood flow to the kidneys and an increase in the glomerular filtration rate (GFR), allowing for more efficient filtering of the blood. The patient’s symphysis-fundal height is within the expected range, indicating that the baby is not macrosomic. The patient does not exhibit symptoms of gestational diabetes, such as polyuria, polydipsia, or nocturia, and does not have any risk factors for the condition. Therefore, arranging for a fasting glucose test is not the best option for diagnosing or excluding gestational diabetes. Instead, an OGTT should be considered the gold standard. Prescribing labetalol is not necessary as the patient does not exhibit any concerning signs of pre-eclampsia. Similarly, prescribing metformin is not indicated as the patient has not been diagnosed with gestational diabetes and does not require medication for diabetes at this time.

Physiological Changes During Pregnancy

The human body undergoes significant physiological changes during pregnancy. The cardiovascular system experiences an increase in stroke volume by 30%, heart rate by 15%, and cardiac output by 40%. However, systolic blood pressure remains unchanged, while diastolic blood pressure decreases in the first and second trimesters, returning to non-pregnant levels by term. The enlarged uterus may interfere with venous return, leading to ankle edema, supine hypotension, and varicose veins.

The respiratory system sees an increase in pulmonary ventilation by 40%, with tidal volume increasing from 500 to 700 ml due to the effect of progesterone on the respiratory center. Oxygen requirements increase by only 20%, leading to over-breathing and a fall in pCO2, which can cause a sense of dyspnea accentuated by the elevation of the diaphragm. The basal metabolic rate increases by 15%, possibly due to increased thyroxine and adrenocortical hormones, making warm conditions uncomfortable for women.

The maternal blood volume increases by 30%, mostly in the second half of pregnancy. Red blood cells increase by 20%, but plasma increases by 50%, leading to a decrease in hemoglobin. There is a low-grade increase in coagulant activity, with a rise in fibrinogen and Factors VII, VIII, X. Fibrinolytic activity decreases, returning to normal after delivery, possibly due to placental suppression. This prepares the mother for placental delivery but increases the risk of thromboembolism. Platelet count falls, while white blood cell count and erythrocyte sedimentation rate rise.

The urinary system experiences an increase in blood flow by 30%, with glomerular filtration rate increasing by 30-60%. Salt and water reabsorption increase due to elevated sex steroid levels, leading to increased urinary protein losses. Trace glycosuria is common due to the increased GFR and reduction in tubular reabsorption of filtered glucose.

Calcium requirements increase during pregnancy, especially during the third trimester and lactation. Calcium is transported actively across the placenta, while serum levels of calcium and phosphate fall with a fall in protein. Ionized levels of calcium remain stable, and gut absorption of calcium increases substantially due to increased 1,25 dihydroxy vitamin D.

The liver experiences an increase in alkaline phosphatase by 50%,

When a pregnant woman with a confirmed DVT is suspected of having a PE, the first step is to immediately administer LMWH to avoid any delay in treatment. PE during pregnancy can be life-threatening for both the mother and the foetus, causing hypoxia and even cardiac arrest. Thrombolysis is not recommended during pregnancy as it can lead to severe haemorrhage in the placenta and foetus. Apixaban is not approved for use during pregnancy and may have teratogenic effects. Similarly, warfarin is not safe during pregnancy and can cause congenital malformations and haemorrhage in the placenta. While a CTPA can be diagnostic, waiting for the scan can be risky for the mother and baby. Therefore, LMWH should be started without delay, and further investigations can be carried out to confirm or rule out a PE.

Investigation of DVT/PE during Pregnancy

Guidelines for investigating deep vein thrombosis (DVT) and pulmonary embolism (PE) during pregnancy were updated in 2015 by the Royal College of Obstetricians. For suspected DVT, compression duplex ultrasound should be performed if there is clinical suspicion. In cases of suspected PE, an ECG and chest x-ray should be performed in all patients. If a woman presents with symptoms and signs of DVT, compression duplex ultrasound should be performed. If DVT is confirmed, no further investigation is necessary, and treatment for venous thromboembolism (VTE) should continue. The decision to perform a ventilation/perfusion (V/Q) scan or computed tomography pulmonary angiography (CTPA) should be made at a local level after discussion with the patient and radiologist.

When comparing CTPA to V/Q scanning in pregnancy, it is important to note that CTPA slightly increases the lifetime risk of maternal breast cancer (up to 13.6%, with a background risk of 1/200 for the study population). Pregnancy makes breast tissue particularly sensitive to the effects of radiation. On the other hand, V/Q scanning carries a slightly increased risk of childhood cancer compared to CTPA (1/50,000 versus less than 1/1,000,000). It is also important to note that D-dimer is of limited use in the investigation of thromboembolism during pregnancy as it is often raised in pregnant women.

In the event of cord prolapse, which occurs when the umbilical cord descends below the presenting part of the fetus after membrane rupture, fetal hypoxia and death can occur due to cord compression or spasm. To prevent compression, tocolytics should be administered and a Caesarean delivery should be performed. The patient should be advised to assume an all-fours position. It is important not to push the cord back into the uterus. The preferred method of delivery is an immediate Caesarean section.

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.

The ‘triple test’ can be utilized at 16 weeks, but its accuracy is lower than the ‘combined test’. Therefore, it should only be employed when screening for trisomy is conducted after 14 weeks. The test involves conducting blood tests for AFP, -HCG, and oestriol. One should note that the false positive rate may be higher with this test.

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.

A planned caesarean section at 37 weeks gestation is the appropriate course of action for a patient who has a classical caesarean scar. This type of scar, which is characterized by a vertical incision on the abdomen, is a contraindication for vaginal birth after caesarean due to the increased risk of uterine rupture. A vaginal delivery should not be considered in this scenario as it could be potentially fatal for both the mother and the baby. It is important to ensure that the caesarean section is performed in a hospital setting. A caesarean section at 36 weeks is not recommended, and guidelines suggest that the procedure should be performed at 37 weeks or later.

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 recommended position for women with cord prolapse is on all fours, with their knees and elbows on the ground. It is important to avoid pushing the cord back in, but to keep it warm and moist. This position helps to prevent compression of the presenting part of the fetus. However, immediate preparations for a caesarian section should also be made. The Trendelenburg position, which involves tilting the head end of the bed downwards, is not recommended for cord prolapse. The Lloyd Davis position, which involves separating the legs, is also not recommended. The McRoberts manoeuvre, which involves hyper-flexing the legs tightly to the abdomen, is used for shoulder dystocia during vaginal delivery and is not appropriate for cord prolapse. The lithotomy position, which involves raising the legs in stirrups, is commonly used in obstetrics and gynaecology but is not recommended for 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.

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.

Diagnosis and Management of Pre-eclampsia in Pregnancy

Pre-eclampsia is a serious condition that can occur during pregnancy, characterized by hypertension, proteinuria, and edema. It can lead to various complications and is a leading cause of maternal death. Risk factors include nulliparity, previous history of pre-eclampsia, family history, and certain medical conditions. Diagnosis is made by testing for proteinuria and monitoring blood pressure. Treatment involves close monitoring, medication, and delivery of the baby. Complications can include HELLP syndrome and eclampsia. Testing for liver function and performing a CTG can aid in management, but will not lead to the diagnosis. Early identification and management are crucial in preventing adverse outcomes.

Breastfeeding is generally safe with most anti-epileptic drugs, including Lamotrigine which is commonly prescribed for seizures. It is a preferred option for women as it does not affect their ability to bear children. However, Carbimazole and Diazepam active metabolite can be passed on to the baby through breast milk and should be avoided. Isotretinoin effect on breastfed infants is not well studied, but oral retinoids should generally be avoided while breastfeeding.

Pregnancy and breastfeeding can be a concern for women with epilepsy. It is generally recommended that women continue taking their medication during pregnancy, as the risks of uncontrolled seizures outweigh the potential risks to the fetus. However, it is important for women to take folic acid before pregnancy to reduce the risk of neural tube defects. The use of antiepileptic medication during pregnancy can increase the risk of congenital defects, but this risk is still relatively low. It is recommended to aim for monotherapy and there is no need to monitor drug levels. Sodium valproate is associated with neural tube defects, while carbamazepine is considered the least teratogenic of the older antiepileptics. Phenytoin is associated with cleft palate, and lamotrigine may require a dose increase during pregnancy. Breastfeeding is generally safe for mothers taking antiepileptics, except for barbiturates. Pregnant women taking phenytoin should be given vitamin K in the last month of pregnancy to prevent clotting disorders in the newborn.

A warning has been issued about the use of sodium valproate during pregnancy and in women of childbearing age. New evidence suggests a significant risk of neurodevelopmental delay in children following maternal use of this medication. Therefore, it should only be used if clearly necessary and under specialist neurological or psychiatric advice. It is important for women with epilepsy to discuss their options with their healthcare provider and make informed decisions about their treatment during pregnancy and breastfeeding.

If a pregnant woman who is not immune to chickenpox is exposed to the virus, it is crucial to offer varicella-zoster immunoglobulin (VZIG) within 10 days of the exposure to reduce the risk of foetal varicella-zoster syndrome and potential complications for the mother. However, if the woman is under 20 weeks pregnant, oral acyclovir is not recommended as there is limited evidence for its efficacy in this situation. Giving both VZIG and oral acyclovir is impractical and inappropriate, especially since the woman has already been exposed to chickenpox. If the woman develops chickenpox before 20 weeks gestation, acyclovir may be considered, but VZIG should still be given to reduce the chance of severe infection. It is important to note that VZIG should be given before symptoms develop and is only effective up to 10 days post-exposure. Therefore, waiting for symptoms to appear before giving VZIG is not recommended.

Chickenpox exposure in pregnancy can pose risks to both the mother and fetus, including fetal varicella syndrome. Post-exposure prophylaxis (PEP) with varicella-zoster immunoglobulin (VZIG) or antivirals should be given to non-immune pregnant women, with timing dependent on gestational age. If a pregnant woman develops chickenpox, specialist advice should be sought and oral acyclovir may be given if she is ≥ 20 weeks and presents within 24 hours of onset of the rash.

Minimizing Teratogenicity in Antiepileptic Medications for Women Wishing to Start a Family

For women with epilepsy who wish to start a family, it is crucial to minimize exposure to teratogenic antiepileptic medications while still controlling their seizures. Sodium valproate, a commonly used antiepileptic drug, is highly teratogenic and associated with congenital malformations and neural tube defects. Therefore, it is recommended to change medication prior to conception, as advised by an epilepsy specialist after a thorough evaluation of risks and benefits.

One option may be to add levetiracetam to the current medication regimen, as it is a pregnancy category C drug that may help control seizures. However, carbamazepine or lamotrigine may be preferred based on limited evidence.

Stopping sodium valproate and starting phenytoin is not recommended, as phenytoin also carries a significant risk of teratogenicity and has toxic and side effects.

Increasing the dose of sodium valproate is not advised, as it can negatively affect fetal neurodevelopment.

Similarly, stopping sodium valproate and adding phenobarbital is not indicated, as phenobarbital is also associated with an increased risk of teratogenicity.

Overall, it is important for women with epilepsy who wish to start a family to consult with an epilepsy specialist to evaluate and recommend appropriate antiepileptic medication changes to minimize teratogenicity while still controlling seizures.

The most probable condition is cholestasis of pregnancy, which is indicated by intense itching, jaundice, obstructive liver function tests, normal white blood cell count, and absence of coagulopathy. Severe itching is a typical symptom of cholestasis of pregnancy, while acute fatty liver of pregnancy presents with non-specific symptoms such as fatigue, malaise, and nausea. Given the normal results of the full blood count and viral screening, it is unlikely that the patient has HELLP syndrome or viral hepatitis. Lastly, pre-eclampsia is characterized by high blood pressure and protein in the urine.

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.

Treatment options for pre-existing hypertension in pregnancy

Explanation: Pre-existing hypertension in pregnancy requires careful management to ensure the safety of both the mother and the baby. When treating hypertension in pregnancy, it is important to consider the potential adverse effects of medication on fetal development.

One option is to discontinue antihypertensive treatment as blood pressure drops in the first trimester. However, this is not recommended as high blood pressure in pregnancy can have significant implications.

Continuing ramipril at the current dose or increasing the dose is not recommended as ACE inhibitors have been associated with fetal malformations. NICE guidelines suggest stopping ACE inhibitors and ARBs as soon as the patient knows she is pregnant or at the first opportunity such as the booking visit.

The first-line treatment for hypertension in pregnancy is labetalol, but it should be avoided in patients with asthma. Second-line medications include nifedipine, a calcium channel blocker, and methyldopa. Methyldopa should be avoided in patients with a history of depression. Therefore, the safest choice in this scenario is nifedipine. It is important to prescribe nifedipine by brand name and continue with the same brand throughout the course of treatment, provided there are no side-effects.

Risk Factors for Pre-eclampsia in Pregnancy

Pre-eclampsia is a serious disorder of pregnancy that can lead to life-threatening complications if left untreated. It is important to identify risk factors for pre-eclampsia in order to provide appropriate monitoring and care for pregnant women.

Known hypertension is a significant risk factor for pre-eclampsia. Women with hypertension should be closely monitored throughout their pregnancy.

Age is also a factor, with women over 40 being at increased risk. However, the patient in this scenario is 28 years old and not at increased risk.

First pregnancy or first pregnancy with a new partner is a risk factor for pre-eclampsia. However, as this is the patient’s second pregnancy with the same partner, she is not at increased risk.

A high BMI is a risk factor for pre-eclampsia, particularly if a patient’s BMI is over 35. However, a low BMI, such as the patient’s BMI of 17, is not a risk factor.

Finally, a period of ten years or more since the last pregnancy is a moderate risk factor for pre-eclampsia. As the patient has a child that is four years old, she is not at increased risk.

In conclusion, identifying and monitoring risk factors for pre-eclampsia is crucial in ensuring the health and safety of pregnant women and their babies.

Hyperemesis gravidarum is more likely to occur in women who are pregnant with multiple babies. Other factors that may increase the risk of HG include obesity, epilepsy, stress, and a family history of the condition. Treatment options may include corticosteroids like prednisolone, anti-emetic drugs such as ondansetron, and vitamins B6 and B12. While advanced maternal age can increase the risk of certain pregnancy complications, it has not been linked to an increased risk of HG. Similarly, having multiple previous pregnancies does not appear to increase the risk of HG, but a history of the condition in a previous pregnancy may be a risk factor.

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.

Obesity is the only factor among the given options that has been linked to miscarriage. Other factors such as heavy lifting, bumping your tummy, having sex, air travel, and being stressed have not been associated with an increased risk of miscarriage. However, factors like increased maternal age, smoking in pregnancy, consuming alcohol, recreational drug use, high caffeine intake, infections and food poisoning, health conditions, and certain medicines have been linked to an increased risk of miscarriage. Additionally, an unusual shape or structure of the womb and cervical incompetence can also increase the risk of miscarriage.

Miscarriage: Understanding the Epidemiology

Miscarriage, also known as abortion, refers to the expulsion of the products of conception before 24 weeks. To avoid any confusion, the term miscarriage is often used. According to epidemiological studies, approximately 15-20% of diagnosed pregnancies will end in miscarriage during early pregnancy. In fact, up to 50% of conceptions may not develop into a blastocyst within 14 days.

Recurrent spontaneous miscarriage, which is defined as the loss of three or more consecutive pregnancies, affects approximately 1% of women. Understanding the epidemiology of miscarriage is important for healthcare providers and patients alike. It can help to identify risk factors and provide appropriate counseling and support for those who have experienced a miscarriage. By raising awareness and promoting education, we can work towards reducing the incidence of miscarriage and improving the overall health and well-being of women and their families.

To monitor her throughout her pregnancy and postnatal period, this woman requires a referral to a perinatal mental health team due to her increased risk of postpartum psychosis. It would have been preferable for her to receive preconception advice before becoming pregnant. The recurrence rate is not influenced by the baby’s gender.

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.

In cases where the previous method is unsuccessful, an episiotomy may be necessary to facilitate internal maneuvers. Various alternatives may be considered, such as…

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.

To evaluate a patient with suspected premature rupture of membranes, a thorough medical history should be obtained, including the number of pregnancies. A sterile speculum examination is necessary to check for the accumulation of amniotic fluid in the posterior vaginal vault. Digital examination should be avoided to prevent infection. Serum beta-HCG is not recommended, and the patient should have had previous ultrasound scans and have confirmed her pregnancy by this stage. Ultrasound is the appropriate diagnostic tool if there is no evidence of amniotic fluid pooling in the posterior vaginal vault.

Preterm prelabour rupture of the membranes (PPROM) is a condition that occurs in approximately 2% of pregnancies, but it is responsible for around 40% of preterm deliveries. This condition can lead to various complications, including prematurity, infection, and pulmonary hypoplasia in the fetus, as well as chorioamnionitis in the mother. To confirm PPROM, a sterile speculum examination should be performed to check for pooling of amniotic fluid in the posterior vaginal vault. However, digital examination should be avoided due to the risk of infection. If pooling of fluid is not observed, testing the fluid for placental alpha microglobulin-1 protein (PAMG-1) or insulin-like growth factor binding protein-1 is recommended. Ultrasound may also be useful to show oligohydramnios.

The management of PPROM involves admission and regular observations to ensure that chorioamnionitis is not developing. Oral erythromycin should be given for ten days, and antenatal corticosteroids should be administered to reduce the risk of respiratory distress syndrome. Delivery should be considered at 34 weeks of gestation, but there is a trade-off between an increased risk of maternal chorioamnionitis and a decreased risk of respiratory distress syndrome as the pregnancy progresses. PPROM is a serious condition that requires prompt diagnosis and management to minimize the risk of complications for both the mother and the fetus.

Women on antiepileptics trying to conceive should receive 5mg folic acid. Letrozole and clomiphene are not appropriate for this patient. Adequate control of epilepsy is important and medication changes should be made by a specialist. This patient should be started on a high dose of folic acid due to the risk of neural tube defects.

Folic Acid: Importance, Deficiency, and Prevention

Folic acid is a vital nutrient that is converted to tetrahydrofolate (THF) in the body. It is found in green, leafy vegetables and plays a crucial role in the transfer of 1-carbon units to essential substrates involved in the synthesis of DNA and RNA. However, certain factors such as phenytoin, methotrexate, pregnancy, and alcohol excess can cause a deficiency in folic acid. This deficiency can lead to macrocytic, megaloblastic anemia and neural tube defects.

To prevent neural tube defects during pregnancy, it is recommended that all women take 400mcg of folic acid until the 12th week of pregnancy. Women at higher risk of conceiving a child with a neural tube defect should take 5mg of folic acid from before conception until the 12th week of pregnancy. Women are considered higher risk if they or their partner has a neural tube defect, they have had a previous pregnancy affected by a neural tube defect, or they have a family history of a neural tube defect. Additionally, women with certain medical conditions such as coeliac disease, diabetes, or thalassaemia trait, or those taking antiepileptic drugs, or who are obese (BMI of 30 kg/m2 or more) are also considered higher risk.

In summary, folic acid is an essential nutrient that plays a crucial role in DNA and RNA synthesis. Deficiency in folic acid can lead to serious health consequences, including neural tube defects. However, taking folic acid supplements during pregnancy can prevent these defects and ensure a healthy pregnancy.

The patient can still take metformin but should discontinue gliclazide. When managing type 2 diabetes during pregnancy, metformin can be used alone or with insulin for women with pre-existing diabetes. Although the patient may need to switch to insulin, it is not always necessary. However, both liraglutide and gliclazide are not safe to use during pregnancy.

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.

Different Types of Miscarriage: Symptoms and Diagnosis

Miscarriage is the loss of pregnancy before 20 weeks’ gestation. There are several types of miscarriage, each with its own symptoms and diagnosis.

Missed miscarriage is an incidental finding where the patient presents without symptoms, but the ultrasound shows a small gestational sac and no fetal heart rate.

Complete miscarriage is when all products of conception have been passed, and the uterus is empty and contracted.

Incomplete miscarriage is when some, but not all, products of conception have been expelled, and the patient experiences vaginal bleeding with an open or closed os.

Inevitable miscarriage is when the pregnancy will inevitably be lost, and the patient presents with active bleeding, abdominal pain, and an open cervical os.

Threatened miscarriage is when there is an episode of bleeding, but the pregnancy is unaffected, and the patient experiences cyclical abdominal pain and dark red-brown bleeding. The cervical os is closed, and ultrasound confirms the presence of a gestational sac and fetal heart rate.

It is important to seek medical attention if any symptoms of miscarriage occur.

Gestational hypertension is a condition where a woman develops high blood pressure after 20 weeks of pregnancy, without significant protein in the urine. This woman has moderate gestational hypertension, with her systolic blood pressure ranging between 150-159 mmHg and diastolic blood pressure ranging between 100-109 mmHg.

Typically, moderate gestational hypertension does not require hospitalization and can be treated with oral labetalol. However, as this woman has a history of asthma, labetalol is not recommended. Instead, NICE guidelines suggest nifedipine or methyldopa as alternatives. Methyldopa is not recommended for patients with depression, so the best option for this woman is oral nifedipine, which is a calcium channel blocker.

In cases of eclampsia, IV magnesium sulphate is necessary. It’s important to note that lisinopril, an ACE inhibitor, is not safe for use during pregnancy.

Hypertension during pregnancy is a common occurrence that requires careful management. In normal pregnancies, blood pressure tends to decrease in the first trimester and then gradually increase to pre-pregnancy levels by term. However, in cases of hypertension during pregnancy, the systolic blood pressure is usually above 140 mmHg or the diastolic blood pressure is above 90 mmHg. Additionally, an increase of more than 30 mmHg systolic or 15 mmHg diastolic from the initial readings may also indicate hypertension.

There are three categories of hypertension during pregnancy: pre-existing hypertension, pregnancy-induced hypertension (PIH), and pre-eclampsia. Pre-existing hypertension refers to a history of hypertension before pregnancy or elevated blood pressure before 20 weeks gestation. PIH occurs in the second half of pregnancy and resolves after birth. Pre-eclampsia is characterized by hypertension and proteinuria, and may also involve edema.

The management of hypertension during pregnancy involves the use of antihypertensive medications such as labetalol, nifedipine, and hydralazine. In cases of pre-existing hypertension, ACE inhibitors and angiotensin II receptor blockers should be stopped immediately and alternative medications should be prescribed. Women who are at high risk of developing pre-eclampsia should take aspirin from 12 weeks until the birth of the baby. It is important to carefully monitor blood pressure and proteinuria levels during pregnancy to ensure the health of both the mother and the baby.
