Breast Conditions in Lactating Women

Lactating women may experience various breast conditions, including mastitis, breast abscess, cellulitis, engorged breasts, and full breasts.

Mastitis is typically caused by a blocked duct or ascending infection from nipple trauma during breastfeeding. Symptoms include unilateral pain, breast engorgement, and erythema. Treatment involves analgesia, reassurance, and continuing breastfeeding. Antibiotics may be necessary if symptoms persist or a milk culture is positive.

Breast abscess presents as a painful lump in the breast tissue, often with systemic symptoms such as fever and malaise. Immediate treatment is necessary to prevent septicaemia.

Cellulitis is an acute bacterial infection of the breast skin, presenting with erythema, tenderness, swelling, and blister formation. Non-specific symptoms such as rigors, fevers, and malaise may also occur.

Engorged breasts can be primary or secondary, causing bilateral breast pain and engorgement. The skin may appear shiny, and the nipple may appear flat due to stretching.

Full breasts are associated with lactation and cause warm, heavy, and hard breasts. This condition typically occurs between the 2nd and 6th day postpartum.

Possible Causes of Hirsutism in Women: A Differential Diagnosis

Hirsutism, the excessive growth of hair in women in a male pattern, can be caused by various underlying conditions. Here are some possible causes and their distinguishing features:

Molar Pregnancy: This condition is characterized by hypertension in the first trimester of pregnancy. Excessive stimulation of ovarian follicles by high levels of gonadotrophins or human chorionic gonadotrophin (hCG) can lead to the formation of multiple theca lutein cysts bilaterally.

Congenital Adrenal Hyperplasia: This disease, which is mostly found in women, can present with gradual onset of hirsutism without virilization. It is caused by a deficiency of 21-hydroxylase and is characterized by an elevated serum concentration of 17-hydroxyprogesterone.

Luteoma of Pregnancy: This benign, solid ovarian tumor develops during pregnancy and disappears after delivery. It may be associated with excess androgen production, leading to hirsutism and virilization.

Adrenal Tumor: Androgen-secreting adrenal tumors can cause rapid onset of severe hirsutism, with or without virilization. Amenorrhea is found in almost half of the patients, and testosterone and dihydrotestosterone sulfate concentrations are elevated.

Polycystic Ovary Syndrome: Women with this condition are at higher risk of developing pre-eclampsia. However, the development of hypertension in the first trimester of pregnancy makes it more likely that there is a molar pregnancy present, with theca lutein cysts seen on ultrasound.

In summary, hirsutism in women can be caused by various conditions, and a differential diagnosis is necessary to determine the underlying cause and appropriate treatment.

The situation involves cord prolapse leading to cord compression and variable decelerations on the CTG. The RCOG has issued guidelines (Green-top Guidelines No.50) for managing cord prolapse. The guidelines recommend elevating the presenting part either manually or by filling the urinary bladder to prevent cord compression. If fetal heart rate anomalies persist despite using mechanical methods to prevent compression, tocolysis (such as terbutaline) can be considered while preparing for a 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 position of the head in relation to the ischial spine is referred to as the station. When the head is at the same level as the ischial spines, the station is considered to be ‘0’. If the station is described as ‘-2’, it means that the head is 2 cm above the ischial spines, while a station of ‘+2’ indicates that the head is 2 cm below the ischial spine.

Induction of labour is a process where labour is artificially started and is required in about 20% of pregnancies. It is indicated in cases of prolonged pregnancy, prelabour premature rupture of the membranes, maternal medical problems, diabetic mother over 38 weeks, pre-eclampsia, obstetric cholestasis, and intrauterine fetal death. The Bishop score is used to assess whether induction of labour is necessary and includes cervical position, consistency, effacement, dilation, and fetal station. A score of less than 5 indicates that labour is unlikely to start without induction, while a score of 8 or more indicates a high chance of spontaneous labour or response to interventions made to induce labour.

Possible methods of induction include membrane sweep, vaginal prostaglandin E2, oral prostaglandin E1, maternal oxytocin infusion, amniotomy, and cervical ripening balloon. The NICE guidelines recommend vaginal prostaglandins or oral misoprostol if the Bishop score is less than or equal to 6, while amniotomy and an intravenous oxytocin infusion are recommended if the score is greater than 6.

The main complication of induction of labour is uterine hyperstimulation, which refers to prolonged and frequent uterine contractions that can interrupt blood flow to the intervillous space and result in fetal hypoxemia and acidemia. Uterine rupture is a rare but serious complication. Management includes removing vaginal prostaglandins and stopping the oxytocin infusion if one has been started, and considering tocolysis.

Placental Abnormalities: Understanding the Spectrum of Disease

Placental abnormalities can range from mild to severe, with varying degrees of risk to both mother and baby. Placenta increta is a condition where the placenta infiltrates into the myometrium, while placenta percreta is the most severe form where the placental fibres invade beyond the myometrium and require a hysterectomy for management. Placenta accreta is a milder form where the placental fibres attach to the superficial layer of the myometrium. Placenta praevia is a common cause of antepartum haemorrhage, where the placenta lies low and covers part of the internal cervical os. Vasa praevia is a condition where fetal vessels run across or over part of the internal cervical os, increasing the risk of bleeding and fetal distress.

Risk factors for these conditions include previous Caesarean section, myomectomy, multiparity, maternal age >35, placenta praevia, and uterine anomalies. Diagnosis is typically made through ultrasound, with MRI used in severe cases. Management may involve a Caesarean section for delivery in a controlled setting, or in severe cases, a hysterectomy. Women with vasa praevia or placenta praevia are advised to have an elective Caesarean section to reduce the risk of complications. Understanding the spectrum of placental abnormalities is crucial for appropriate management and reducing the risk of maternal and fetal complications.

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.

Safe antihypertensive Medications for Pregnancy

Explanation:
When planning to get pregnant, it is important to ensure that any medications being taken are safe for the developing fetus. In the case of hypertension, switching to a safe medication prior to conception is recommended. Labetalol is the best-studied antihypertensive in pregnancy and is considered safe. Losartan, on the other hand, is contraindicated as it may affect renal development. Simply reducing the dosage of losartan is not enough to mitigate the risks of fetal maldevelopment. It is also important to maintain good blood pressure control prior to conception. Stopping antihypertensive medications abruptly is not recommended as it may lead to uncontrolled hypertension, which is associated with increased fetal loss. By taking these precautions, women can increase their chances of carrying a healthy fetus to term.

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.

The McRobert’s manoeuvre is an efficient and uncomplicated method to address shoulder dystocia. By enhancing the flexibility of the sacroiliac joints, it facilitates pelvic rotation and the subsequent release of the fetal shoulder. It is crucial to immediately seek assistance upon identifying shoulder dystocia.

The correct answer for the management of gestational diabetes is insulin. If the fasting glucose level is equal to or greater than 7 mmol/L at the time of diagnosis, insulin should be initiated. Diet and exercise/lifestyle advice alone is not sufficient for managing gestational diabetes and medication is necessary. Empagliflozin and glibenclamide are not appropriate treatments for gestational diabetes. Glibenclamide may only be considered if the patient has declined insulin.

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.

Folic Acid Supplementation in Pregnancy

Explanation: Folic acid supplementation is recommended for all women who are trying to conceive and during pregnancy to reduce the risk of neural tube defects and other congenital abnormalities. The recommended dose is 400 micrograms daily from the preconception period until the 12th week of gestation. However, women with certain high-risk factors, such as diabetes, a family history of neural tube defects, or obesity, are advised to take a higher dose of 5 mg daily from the preconception period until the 12th week of gestation. It is important to continue folic acid supplementation until the end of the first trimester to ensure proper formation of the brain and other major organs in the body. Side-effects of folic acid treatment may include abdominal distension, reduced appetite, nausea, and exacerbation of pernicious anaemia.

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 patient’s immunity to varicella-zoster needs to be determined urgently by testing for varicella-zoster IgG antibodies in the blood, as she has had some exposure to chickenpox and is unsure of her immunity status. If antibodies are detected, she is considered immune and no further action is required, but she should seek medical care immediately if she develops a rash. Varicella-zoster immunoglobulin should only be administered to non-immune patients within 10 days of exposure. It is important to note that if the patient contracts chickenpox during pregnancy, there is a risk of fetal varicella syndrome if infected before 28 weeks’ gestation. Immunisation during pregnancy is not recommended, but the patient can receive the vaccine postpartum if found to be non-immune. It is safe to receive the vaccine while breastfeeding.

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 MMR vaccine, which contains live attenuated virus, should not be given to women who are pregnant or trying to conceive. It is recommended that women avoid getting pregnant for at least 28 days after receiving the vaccine. If a pregnant woman is not immune to MMR, she should avoid contact with individuals who have the disease. In the event that a woman receives the MMR vaccine unintentionally during the periconception period or early pregnancy, termination of pregnancy is not necessary. This information is based on the guidelines provided by the American College of Obstetricians and Gynecologists.

Rubella and Pregnancy: Risks, Features, Diagnosis, and Management

Rubella, also known as German measles, is a viral infection caused by the togavirus. Thanks to the introduction of the MMR vaccine, it is now rare. However, if contracted during pregnancy, there is a risk of congenital rubella syndrome, which can cause serious harm to the fetus. It is important to note that the incubation period is 14-21 days, and individuals are infectious from 7 days before symptoms appear to 4 days after the onset of the rash.

The risk of damage to the fetus is highest in the first 8-10 weeks of pregnancy, with a risk as high as 90%. However, damage is rare after 16 weeks. Features of congenital rubella syndrome include sensorineural deafness, congenital cataracts, congenital heart disease (e.g. patent ductus arteriosus), growth retardation, hepatosplenomegaly, purpuric skin lesions, ‘salt and pepper’ chorioretinitis, microphthalmia, and cerebral palsy.

If a suspected case of rubella in pregnancy arises, it should be discussed immediately with the local Health Protection Unit (HPU) as type/timing of investigations may vary. IgM antibodies are raised in women recently exposed to the virus. It should be noted that it is very difficult to distinguish rubella from parvovirus B19 clinically. Therefore, it is important to also check parvovirus B19 serology as there is a 30% risk of transplacental infection, with a 5-10% risk of fetal loss.

If a woman is tested at any point and no immunity is demonstrated, they should be advised to keep away from people who might have rubella. Non-immune mothers should be offered the MMR vaccination in the post-natal period. However, MMR vaccines should not be administered to women known to be pregnant or attempting to become pregnant.

The initial investigation for preterm prelabour rupture of the membranes is a thorough speculum examination to check for the accumulation of amniotic fluid in the posterior vaginal vault. It is recommended to avoid bimanual examination to minimize the risk of infection. While cardiotocography can be used to assess foetal wellbeing, it is not the preferred first-line investigation. Foetal blood sampling is not the recommended initial investigation due to the potential risks of infection and miscarriage.

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.

It is recommended to wait until the lady reaches 36 weeks of pregnancy to check if the baby has changed position, as she is currently only 30 weeks pregnant. For nulliparous women, such as the lady in this case, ECV should be provided at 36 weeks if the baby remains in the breech position. However, if the lady had previous pregnancies, ECV would be offered at 37 weeks.

Breech presentation occurs when the caudal end of the fetus is in the lower segment, and it is more common at 28 weeks than near term. Risk factors include uterine malformations, placenta praevia, and fetal abnormalities. Management options include spontaneous turning, external cephalic version (ECV), planned caesarean section, or vaginal delivery. The RCOG recommends informing women that planned caesarean section reduces perinatal mortality and early neonatal morbidity, but there is no evidence that the long-term health of babies is influenced by how they are born. ECV is contraindicated in certain cases, such as where caesarean delivery is required or there is an abnormal cardiotocography.

Management of Prolonged First Stage of Labour: Interventions and Considerations

When a patient experiences a prolonged first stage of labour, it is important to assess the three categories where problems could arise: Powers, Passage, and Passenger. In the case of a primigravida who is achieving less than 0.5 cm per hour over the past 6 hours, and with irregular, non-powerful contractions, the first step is to perform a vaginal examination to assess cervical dilation, fetal position and presentation, and membrane integrity. If the membranes are intact, an amniotomy or artificial rupture of membranes can be performed to accelerate the first stage of labour. Progress is then reassessed by vaginal examination after two hours. If progress remains suboptimal, an oxytocin infusion can be commenced, with analgesia taken into consideration. However, oxytocin infusion should be avoided in women with a previous Caesarean section due to the risk of uterine rupture.

If there is no indication of fetal distress, uncontrolled haemorrhage, or other maternal complications, there is no need for a Caesarean section or instrumental delivery at present. However, if fetal distress or serious maternal complications arise, an emergency Caesarean section would be the preferred mode of delivery. In the absence of these indications, an intervention such as amniotomy should be offered early to increase the chances of a normal vaginal delivery before the patient tires. Therefore, reassessment should be done in one hour to ensure timely intervention.

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.

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.

According to the shoulder dystocia guidelines of the Royal College of Obstetrics and Gynaecology, utilizing suprapubic pressure can enhance the efficacy of the McRoberts manoeuvre.

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 prevent neural tube defects, it is recommended that women who are at risk start taking folic acid before conception. The standard dose of 0.4mg should be taken daily until 13 weeks of pregnancy. It is important to start taking folic acid before conception because the neural tube is formed within the first 28 days of embryo development. If a woman waits until after her missed period, any defects may already be present. Women who are at an increased risk of neural tube defects, such as those who have had a previous child with NTD, diabetes mellitus, are on antiepileptic medication, are obese (with a body mass index over 30 kg/m²), are HIV positive and taking co-trimoxazole, or have sickle cell disease, should take an increased dose of 5mg folic acid.

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.

All pregnant women who develop hypertension (systolic blood pressure over 140 mmHg or diastolic blood pressure over 90 mmHg) after 20 weeks of pregnancy should receive a secondary care assessment by a healthcare professional trained in managing hypertensive disorders of pregnancy. It is not recommended to delay this assessment by monitoring blood pressure over several days or providing lifestyle advice alone. The obstetric department may initiate antihypertensive medication and aspirin for the patient, but those with a blood pressure of 160/110 or higher are likely to be admitted for further monitoring and treatment.

Pre-eclampsia is a condition that occurs during pregnancy and is characterized by high blood pressure, proteinuria, and edema. It can lead to complications such as eclampsia, neurological issues, fetal growth problems, liver involvement, and cardiac failure. Severe pre-eclampsia is marked by hypertension, proteinuria, headache, visual disturbances, and other symptoms. Risk factors for pre-eclampsia include hypertension in a previous pregnancy, chronic kidney disease, autoimmune disease, diabetes, chronic hypertension, first pregnancy, and age over 40. Aspirin may be recommended for women with high or moderate risk factors. Treatment involves emergency assessment, admission for observation, and medication such as labetalol, nifedipine, or hydralazine. Delivery of the baby is the most important step in management, with timing depending on the individual case.

The Importance of Breastfeeding and Weaning

Breastfeeding is crucial for a child’s development and should begin within the first hour of life, according to the WHO and UNICEF. For the first six months, exclusive breastfeeding is recommended, with the baby receiving only breast milk for nutrition. Breastfeeding should occur on demand, and breast milk provides numerous benefits for the child’s cognitive, motor, and immune system development.

After six months, weaning should begin with the introduction of solid foods, while breast milk continues to provide at least half of the child’s nutrition. The WHO recommends breastfeeding for up to two years of age or beyond, with breast milk providing at least one-third of the child’s nutrition in the second year of life.

Overall, breastfeeding and weaning play a crucial role in a child’s growth and development, and it is important to follow the recommended guidelines for optimal health outcomes.

The individual is displaying indications of postpartum thyroiditis, an autoimmune disorder that arises as the body returns to regular immunity from the immunosuppressed state during pregnancy. This condition can manifest for up to a year after childbirth, but it typically occurs 3-4 months post-delivery. Beta blockers, not antithyroid medications, should be used to treat the hyperthyroid phase.

Understanding Postpartum Thyroiditis: Stages and Management

Postpartum thyroiditis is a condition that affects some women after giving birth. It is characterized by three stages: thyrotoxicosis, hypothyroidism, and normal thyroid function. During the thyrotoxicosis phase, the thyroid gland becomes overactive, leading to symptoms such as anxiety, palpitations, and weight loss. In the hypothyroidism phase, the thyroid gland becomes underactive, causing symptoms such as fatigue, weight gain, and depression. However, in the final stage, the thyroid gland returns to normal function, although there is a high recurrence rate in future pregnancies.

Thyroid peroxidase antibodies are found in 90% of patients with postpartum thyroiditis, which suggests an autoimmune component to the condition. Management of postpartum thyroiditis depends on the stage of the condition. During the thyrotoxic phase, symptom control is the main focus, and propranolol is typically used. Antithyroid drugs are not usually used as the thyroid gland is not overactive. In the hypothyroid phase, treatment with thyroxine is usually necessary to restore normal thyroid function.

It is important to note that many causes of hypothyroidism may have an initial thyrotoxic phase, as shown in a Venn diagram. Therefore, it is crucial to properly diagnose and manage postpartum thyroiditis to ensure the best possible outcomes for both the mother and the baby.

Understanding Dilutional Anaemia of Pregnancy

Dilutional anaemia of pregnancy is a common condition that occurs during pregnancy. It is characterized by a normal mean cell volume (MCV) and is caused by a disproportional rise in plasma volume, which dilutes the red blood cells. This condition is the most likely option for a patient with a normal MCV.

Iron deficiency anaemia, on the other hand, is microcytic and gives a low MCV. Pancytopenia, which is the term for low haemoglobin, white cells, and platelets, is not applicable in this case as the patient’s white cells and platelets are in the normal range.

Folic acid or B12 deficiency would give rise to macrocytic anaemia with raised MCV, which is not the case for this patient. Myelodysplasia, an uncommon malignant condition that usually occurs in patients over 60, is also unlikely.

In conclusion, understanding dilutional anaemia of pregnancy is important for healthcare professionals to provide appropriate care and management for pregnant patients.

Lactation mastitis is a prevalent inflammatory condition of the breast that can have infectious or non-infectious origins. The primary cause is milk stasis, which can occur due to either overproduction or insufficient removal.

In cases of non-infectious mastitis, the accumulation of milk leads to an inflammatory response. Occasionally, an infection may develop through retrograde spread via a lactiferous duct or a traumatised nipple, with Staphylococcus aureus being the most common organism.

Symptoms of lactation mastitis include breast pain (usually unilateral) accompanied by an erythematosus, warm, and tender area. Patients may also experience fever and flu-like symptoms.

The first-line approach to managing lactation mastitis is conservative, involving analgesia and encouraging effective milk removal (either through continued breastfeeding or expressing from the affected side) to prevent further milk stasis. It is also crucial to ensure proper positioning and attachment during feeding.

If symptoms do not improve after 12-24 hours of conservative management, antibiotics should be prescribed. The first-line choice is oral flucloxacillin (500 mg four times a day for 14 days), or erythromycin if the patient is allergic to penicillin. Co-amoxiclav is the second-line choice.

In cases where conservative and antibiotic management do not improve symptoms, other more serious causes, such as inflammatory breast cancer, should be considered. (Source – CKS mastitis)

Breastfeeding Problems and Their Management

Breastfeeding is a natural process, but it can come with its own set of challenges. Some of the minor problems that breastfeeding mothers may encounter include frequent feeding, nipple pain, blocked ducts, and nipple candidiasis. These issues can be managed by seeking advice on proper positioning, trying breast massage, and using appropriate medication.

Mastitis is a more serious problem that affects around 1 in 10 breastfeeding women. It is characterized by symptoms such as fever, nipple fissure, and persistent pain. Treatment involves the use of antibiotics, such as flucloxacillin, for 10-14 days. Breastfeeding or expressing milk should continue during treatment to prevent complications such as breast abscess.

Breast engorgement is another common problem that causes breast pain in breastfeeding women. It occurs in the first few days after birth and affects both breasts. Hand expression of milk can help relieve the discomfort of engorgement. Raynaud’s disease of the nipple is a less common problem that causes nipple pain and blanching. Treatment involves minimizing exposure to cold, using heat packs, and avoiding caffeine and smoking.

If a breastfed baby loses more than 10% of their birth weight in the first week of life, it may be a sign of poor weight gain. This should prompt consideration of the above breastfeeding problems and an expert review of feeding. Monitoring of weight should continue until weight gain is satisfactory.

If a patient has an ectopic pregnancy, the treatment plan will depend on various factors such as the size and location of the pregnancy, the patient’s overall health, and the potential impact on their fertility. If the pregnancy is small and the patient’s health is stable, they may be able to receive medication to dissolve the pregnancy. However, if the pregnancy is larger or causing severe symptoms, surgery may be necessary.

In cases where surgery is required, the surgeon may attempt to preserve the affected fallopian tube if possible. However, if the tube is severely damaged or the patient has other factors that may affect their fertility, such as age or previous fertility issues, the surgeon may opt to remove the tube completely. This decision will also depend on the patient’s desire for future fertility and the likelihood of requiring further treatment with methotrexate or a salpingectomy. If the patient’s contralateral tube is unaffected, complete removal of the affected tube may be the most appropriate course of action.

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.

The recommended first-line treatment for nausea and vomiting in pregnancy or hyperemesis gravidarum is antihistamines, specifically oral cyclizine. Second-line options include ondansetron and domperidone. Hospital admission may be necessary if the patient cannot tolerate oral medications or fluids, or if symptoms are not controlled with primary care management. There is no indication for oral omeprazole in this case as the patient has not reported any dyspeptic symptoms.

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.

In obstetric operating theatres or surgical vivas, a frequently asked question pertains to the structures that lie between the skin and the fetus during a lower segment Caesarian section. A confident and clear response indicates a sound understanding of local anatomy and the necessary incisions to reach the fetus. The layers between the skin and the fetus include the superficial fascia, deep fascia, anterior rectus sheath, rectus abdominis muscle (which is not cut but rather pushed laterally after incising the linea alba), transversalis fascia, extraperitoneal connective tissue, peritoneum, and uterus.

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 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.
