According to the latest NICE guidance, it is recommended that women aged 55 and over with unexplained symptoms of vaginal discharge should undergo a direct access ultrasound scan to assess for endometrial cancer. This recommendation applies to women who are experiencing these symptoms for the first time or who have thrombocytosis, haematuria (blood in the urine), visible haematuria, low haemoglobin levels, or high blood glucose levels. For more information, please refer to the NICE referral guidelines on the recognition and referral of suspected cancer.

Women who are 18 years or older and have a pelvic mass that is not clearly uterine fibroids should be promptly referred for assessment. In this case, an abdominal X-ray would not provide much useful information, and it is not advisable to take no action at this point. For more information, please refer to the NICE referral guidelines for suspected cancer.

Tranexamic acid is the best choice for this patient because her periods are heavy, but not very painful, and her fibroids are small. Additionally, she wants to start a family soon, so contraceptive options are not as suitable. For more information, you can refer to the NICE guidelines on the assessment and management of heavy menstrual bleeding.

postmenopausal bleeding should always be treated as a potential malignancy until proven otherwise. The first-line investigation for this condition is transvaginal ultrasound (TVUS). This method effectively assesses the risk of endometrial cancer by measuring the thickness of the endometrium.

In postmenopausal women, the average endometrial thickness is much thinner compared to premenopausal women. The likelihood of endometrial cancer increases as the endometrium becomes thicker. Currently, in the UK, an endometrial thickness of 5 mm is considered the threshold.

If the endometrial thickness is greater than 5 mm, there is a 7.3% chance of endometrial cancer. However, if a woman with postmenopausal bleeding has a uniform endometrial thickness of less than 5 mm, the likelihood of endometrial cancer is less than 1%.

In cases where there is a high clinical risk, hysteroscopy and endometrial biopsy should also be performed. The definitive diagnosis is made through histological examination. If the endometrial thickness is greater than 5 mm, an endometrial biopsy is recommended.

This patient is highly likely to have developed a tubo-ovarian abscess (TOA), which is a complication of pelvic inflammatory disease. TOA occurs when a pocket of pus forms in the fallopian tube and/or ovary. If the abscess ruptures, it can lead to sepsis and become life-threatening.

The initial imaging modality of choice is transabdominal and endovaginal ultrasound. This imaging technique often reveals multilocular complex retro-uterine/adnexal masses with debris, septations, and irregular thick walls. These masses can be present on both sides.

Urgent hospital admission is necessary, and the usual management involves draining the abscess and administering intravenous antibiotics. The abscess drainage can be guided by ultrasound or CT scanning.

In some cases, laparotomy or laparoscopy may be required to drain the abscess.

Respiratory alkalosis can be caused by hyperventilation, such as during periods of anxiety. It can also be a result of conditions like pulmonary embolism, CNS disorders (such as stroke or encephalitis), altitude, pregnancy, or the early stages of aspirin overdose.

Respiratory acidosis is often associated with chronic obstructive pulmonary disease (COPD) or life-threatening asthma. Other causes include pulmonary edema, sedative drug overdose (such as opiates or benzodiazepines), neuromuscular disease, obesity, or certain medications.

Metabolic alkalosis can occur due to vomiting, potassium depletion (often caused by diuretic usage), Cushing’s syndrome, or Conn’s syndrome.

Metabolic acidosis with a raised anion gap can be caused by conditions like lactic acidosis (which can result from hypoxemia, shock, sepsis, or infarction) or ketoacidosis (commonly seen in diabetes, starvation, or alcohol excess). Other causes include renal failure or poisoning (such as late stages of aspirin overdose, methanol, or ethylene glycol).

Metabolic acidosis with a normal anion gap can be attributed to conditions like renal tubular acidosis, diarrhea, ammonium chloride ingestion, or adrenal insufficiency.

Vomiting is a common occurrence during the early stages of pregnancy, typically happening between 7 and 12 weeks. However, there is a more severe form called hyperemesis gravidarum, which affects less than 1% of pregnancies. This condition is characterized by uncontrollable and intense nausea and vomiting, leading to imbalances in fluids and electrolytes, significant ketonuria, nutritional deficiencies, and weight loss.

Hyperemesis gravidarum can result in electrolyte imbalances, particularly hyponatremia and hypokalemia. However, it does not cause hyperkalemia. This persistent vomiting can also lead to other complications such as dehydration, acidosis, deficiencies in vitamins B1, B12, and B6, Mallory-Weiss tears, retinal hemorrhages, pneumothorax, prematurity, and small-for-gestational age babies.

During pregnancy, the vena cava can be compressed by the uterus, leading to a decrease in venous return to the heart. This can worsen the shock state in cases of trauma by reducing cardiac output. To alleviate pressure on the inferior vena cava, the ATLS guidelines recommend manually displacing the uterus to the left side during the primary survey.

If spinal immobilization is necessary, the mother should be log rolled to her left side at a 15-30-degree angle, raising the right side by 10-15 cm. To maintain spinal motion restriction while decompressing the vena cava, a bolstering device like a Cardiff wedge should be used to support the mother.

Pregnancy causes an increase in intravascular volume, which means that pregnant patients can lose a significant amount of blood before showing signs of hypovolemia such as tachycardia and hypotension. Despite stable vital signs, the placenta may not receive adequate perfusion, putting the fetus at risk. Therefore, it is crucial to initiate fluid resuscitation, starting with crystalloid fluids and then using type-specific blood if necessary. Vasopressors should only be used as a last resort to restore maternal blood pressure, as they can further reduce uterine blood flow and lead to fetal hypoxia.

If the mother is rhesus D negative, anti-D immunoglobulin should be administered within 72 hours. However, this is not a priority during the primary survey.

Based on her presentation, the most probable cause of the cardiac arrest in this case is either a pulmonary embolism or amniotic fluid embolism.

When dealing with a cardiac arrest during pregnancy, there are several adjustments that need to be made compared to a regular cardiac arrest situation. These adjustments include:

– Ensuring the presence of an obstetrician
– Having a paediatrician or neonatologist available
– Manually displacing the uterus to the left in order to relieve caval compression
– Tilting the table to the left side, ideally at a 15-30 degree angle
– Performing early tracheal intubation to reduce the risk of aspiration (it is recommended to seek expert anaesthetic assistance for this)
– Initiating preparations for an emergency Caesarean section

In the event of a cardiac arrest, a perimortem Caesarean section should be performed within 5 minutes of the onset. This procedure is crucial as it relieves caval compression, improves the chances of successful resuscitation by increasing venous return during CPR, and maximizes the likelihood of the infant’s survival. The best survival rate for the infant occurs when delivery is achieved within 5 minutes of the mother’s cardiac arrest.

A threatened miscarriage is characterized by bleeding in the first trimester of pregnancy, but without the passing of any products of conception and with a closed cervical os. The main features of a threatened miscarriage include vaginal bleeding, often in the form of brown discharge or spotting, minimal abdominal pain, and a positive pregnancy test. It is important for stable patients who are more than 6 weeks pregnant and experiencing bleeding in early pregnancy, without any signs of an ectopic pregnancy, to seek follow-up care at an early pregnancy assessment unit (EPAU).

Placental abruption, also known as abruptio placentae, occurs when the placental lining separates from the wall of the uterus before delivery and after 20 weeks of gestation.

In the early stages, there may be no symptoms, but typically abdominal pain and vaginal bleeding develop. Approximately 20% of patients experience a concealed placental abruption, where the haemorrhage is confined within the uterine cavity and the amount of blood loss can be significantly underestimated.

The clinical features of placental abruption include sudden onset abdominal pain (which can be severe), variable vaginal bleeding, severe or continuous contractions, abdominal tenderness, and an enlarged, tense uterus. The foetus often shows signs of distress, such as reduced movements, increased or decreased fetal heart rate, decreased variability of fetal heart rate, and late decelerations.

In contrast, placenta praevia is painless and the foetal heart is generally normal. The degree of obstetric shock is usually proportional to the amount of vaginal blood loss. Another clue that the cause of bleeding is placenta praevia rather than placental abruption is that the foetus may have an abnormal presentation or lie.

The primary cause of fetal death in trauma during pregnancy is maternal shock and maternal death. The second most common cause of fetal death is placental abruption. Abruptio placentae can be identified by the following signs: vaginal bleeding (present in 70% of cases), uterine tenderness, frequent uterine contractions, uterine tetany, and uterine irritability. While uterine ultrasonography can be helpful in diagnosing abruptio placentae, it is not definitive. A CT scan may also show signs of abruptio placenta. It is important to note that abruption can occur even after minor injuries later in pregnancy.

Uterine rupture is a much rarer occurrence but is a catastrophic event that leads to rapid maternal and fetal death without immediate surgical intervention. Signs that suggest uterine rupture include vaginal hemorrhage, abdominal tenderness, abdominal guarding and rigidity, rebound tenderness, profound shock, abnormal fetal lie (such as oblique or transverse lie), easy palpation of fetal parts due to their location outside the uterus, and difficulty in palpating the uterine fundus when there is a rupture.

It is crucial to be aware of these signs and symptoms in order to promptly identify and address any potential complications during pregnancy.

Pelvic inflammatory disease (PID) is an infection that affects the upper female reproductive tract, including the uterus, fallopian tubes, and ovaries. It is typically caused by an ascending infection from the cervix. The most common culprits are sexually transmitted diseases like chlamydia and gonorrhea, with chlamydia being the most prevalent infection seen in UK genitourinary medicine clinics.

PID can often be asymptomatic, but when symptoms do occur, they may include lower abdominal pain and tenderness, fever, painful urination, painful intercourse, purulent vaginal discharge, abnormal vaginal bleeding, and tenderness in the cervix and adnexa. It’s important to note that symptoms of ectopic pregnancy can be mistaken for PID, so a pregnancy test should always be conducted in patients with suspicious symptoms.

To investigate a potential case of PID, endocervical swabs are taken to test for chlamydia and gonorrhea using nucleic acid amplification tests. It is recommended to start empirical antibiotic treatment as soon as a presumptive diagnosis of PID is made, without waiting for swab results.

Mild to moderate cases of PID can usually be managed in primary care or outpatient settings. However, patients with severe disease should be admitted to the hospital for intravenous antibiotics. Signs of severe disease include a fever above 38°C, signs of a tubo-ovarian abscess, signs of pelvic peritonitis, or concurrent pregnancy.

The current recommended treatment for outpatient cases of PID is a single intramuscular dose of ceftriaxone 500 mg, followed by oral doxycycline 100 mg twice daily and oral metronidazole 400 mg twice daily for 14 days. An alternative regimen is oral ofloxacin 400 mg twice daily and oral metronidazole 400 mg twice daily for 14 days.

For severely ill patients in the inpatient setting, initial treatment consists of intravenous doxycycline, a single-dose of intravenous ceftriaxone, and intravenous metronidazole. Afterward, the treatment is switched to oral doxycycline and metronidazole to complete a 14-day course.

If a patient fails to respond to treatment, laparoscopy is necessary to confirm the diagnosis or consider alternative diagnoses.

A threatened miscarriage happens when there is bleeding during the first trimester of pregnancy, but no fetal tissue has been expelled, and the opening of the cervix is closed.

If cervical dilatation occurs, a threatened miscarriage can progress to become an inevitable miscarriage. In this case, the pain and bleeding are usually more intense, and upon examination, the cervix will be found to be open.

Eclampsia is the most likely diagnosis in this case. It is characterized by the occurrence of one or more convulsions on top of pre-eclampsia. To control seizures in eclampsia, the recommended treatment is magnesium sulphate. The Collaborative Eclampsia Trial regimen should be followed for administering magnesium sulphate. Initially, a loading dose of 4 g should be given intravenously over 5 to 15 minutes. This should be followed by a continuous infusion of 1 g per hour for 24 hours. If the woman experiences another eclamptic seizure, the infusion should be continued for an additional 24 hours after the last seizure. In case of recurrent seizures, a further dose of 2-4 g should be administered intravenously over 5 to 15 minutes. It is important to note that the only cure for eclampsia is the delivery of the fetus and placenta. Once the patient is stabilized, she should be prepared for an emergency caesarean section.

Functional murmurs, also referred to as physiological or flow murmurs, are frequently observed during pregnancy and other conditions associated with increased blood flow. These murmurs arise as a result of the heightened resting cardiac output and do not necessitate any additional examination.

Eclampsia is the most likely diagnosis in this case. It is characterized by the occurrence of one or more convulsions on top of pre-eclampsia.

If you are a woman under the age of 55 and experiencing postmenopausal bleeding, it is important to seek medical attention promptly. One possible cause of this symptom could be endometrial cancer. To ensure timely diagnosis and treatment, it is recommended to follow the suspected cancer pathway referral guidelines provided by NICE. These guidelines aim to facilitate recognition and referral of suspected cancer cases. By adhering to these guidelines, you can increase the likelihood of securing an appointment for further evaluation within two weeks. to the NICE referral guidelines on recognition and referral of suspected cancer.

Bleeding in a confirmed early pregnancy, along with adnexal tenderness and cervical motion tenderness, is indicative of an ectopic pregnancy until proven otherwise. The amount of bleeding caused by an ectopic pregnancy can range from no bleeding or slight spotting to a level similar to a normal menstrual period. It is important to note that 90% of patients with an ectopic pregnancy experience abdominal pain. Other clinical features that may be present include shoulder tip pain, which is caused by irritation of the diaphragm, as well as adnexal tenderness, cervical motion tenderness, rebound tenderness, guarding, and adnexal masses in some cases. Additionally, hypotension and shock may occur.

Pelvic inflammatory disease (PID) is a pelvic infection that affects the upper female reproductive tract, including the uterus, fallopian tubes, and ovaries. It is typically caused by an ascending infection from the cervix and is commonly associated with sexually transmitted diseases like chlamydia and gonorrhea. In the UK, genital Chlamydia trachomatis infection is the most common cause of PID seen in genitourinary medicine clinics.

PID can often be asymptomatic, but when symptoms are present, they may include lower abdominal pain and tenderness, fever, painful urination, painful intercourse, purulent vaginal discharge, abnormal vaginal bleeding, and tenderness in the cervix and adnexa. It is important to note that symptoms of ectopic pregnancy can be similar to those of PID, so a pregnancy test should be conducted for all patients with suspicious symptoms.

To investigate a possible case of PID, endocervical swabs should be taken to test for C. trachomatis and N. gonorrhoeae using nucleic acid amplification tests if available. Mild to moderate cases of PID can usually be managed in primary care or outpatient settings, while patients with severe disease should be admitted to the hospital for intravenous antibiotics. Signs of severe disease include a fever above 38°C, signs of a tubo-ovarian abscess, signs of pelvic peritonitis, or concurrent pregnancy.

Empirical antibiotic treatment should be initiated as soon as a presumptive diagnosis of PID is made clinically, without waiting for swab results. The current recommended outpatient treatment for PID is a single intramuscular dose of ceftriaxone 500 mg, followed by oral doxycycline 100 mg twice daily and oral metronidazole 400 mg twice daily for 14 days. An alternative regimen is oral ofloxacin 400 mg twice daily and oral metronidazole 400 mg twice daily for 14 days.

Sheehan’s syndrome is a condition where the pituitary gland becomes damaged due to insufficient blood flow and shock during and after childbirth, leading to hypopituitarism. The risk of developing this syndrome is higher in pregnancies with conditions that increase the chances of bleeding, such as placenta praevia and multiple pregnancies. However, Sheehan’s syndrome is quite rare, affecting only 1 in 10,000 pregnancies.

During pregnancy, the anterior pituitary gland undergoes hypertrophy, making it more vulnerable to ischaemia in the later stages. While the posterior pituitary gland is usually not affected due to its own direct blood supply, there have been rare cases where it is involved. In these instances, central diabetes insipidus, a form of posterior pituitary dysfunction, can occur as a complication of Sheehan’s syndrome.

The clinical features of Sheehan’s syndrome include the absence or infrequency of menstrual periods, the inability to produce milk and breastfeed (galactorrhoea), decreased libido, fatigue and tiredness, loss of pubic and axillary hair, and the potential development of secondary hypothyroidism and adrenal insufficiency. Serum prolactin levels are typically low (less than 5ng/ml). An MRI can be helpful in ruling out other pituitary issues, such as a pituitary tumor.

Treatment for Sheehan’s syndrome involves hormone replacement therapy. With appropriate management, the prognosis for this condition is excellent.

Vomiting is a common occurrence during the early stages of pregnancy, typically happening between 7 and 12 weeks. However, there is a more severe condition called hyperemesis gravidarum, which involves uncontrollable and intense nausea and vomiting. This condition can lead to imbalances in fluids and electrolytes, significant ketonuria, malnutrition, and weight loss. It is relatively rare, affecting less than 1% of pregnancies.

For mild cases of nausea and vomiting in early pregnancy, dietary adjustments and non-pharmacological measures like consuming ginger or using P6 wrist acupressure can often provide relief.

In severe cases where heavy ketonuria and severe dehydration are present, hospital admission is usually necessary for intravenous fluid rehydration. The NICE Clinical Knowledge Summary (CKS) on nausea and vomiting in pregnancy recommends using oral promethazine, oral cyclizine, or oral prochlorperazine as the first-line treatment if an antiemetic is needed. After 24 hours, the situation should be reassessed to determine if the initial treatment is effective. If not, a second-line drug like metoclopramide or ondansetron should be considered.

It’s important to note that metoclopramide should not be used in patients under the age of 20 due to the increased risk of extrapyramidal side effects. Additionally, proton pump inhibitors (e.g., omeprazole) and histamine H2-receptor antagonists (e.g., ranitidine) can be beneficial for women experiencing significant dyspepsia alongside their nausea and vomiting.

For more information, you can refer to the NICE CKS on nausea and vomiting in pregnancy.

HELLP syndrome is a condition that occurs in approximately 0.5% of pregnancies. It is characterized by haemolysis, elevated liver enzymes, and a low platelet count. While it typically occurs in the late third trimester, it has also been reported in the late second trimester. Around 33% of patients with HELLP syndrome will present shortly after giving birth.

The initial symptoms of HELLP syndrome can be vague and include nausea, headaches, malaise, and pain in the upper right quadrant of the abdomen. Upon examination, raised blood pressure, proteinuria, and edema may be observed. Further investigations may reveal haemolysis on a blood film, elevated liver enzymes, low platelets, raised LDH, and raised bilirubin.

Delivery of the baby is the main treatment for HELLP syndrome. However, complications can arise, such as disseminated intravascular coagulation (DIC), renal failure, liver failure, and pulmonary edema. It is crucial to tightly control blood pressure, and magnesium sulfate is often used to reduce the risk of progression to eclampsia. If DIC occurs, treatment with fresh frozen plasma is necessary.

Without prompt recognition, approximately 25% of individuals with HELLP syndrome may experience severe complications, including placental abruption, liver failure, retinal detachment, and renal failure. With treatment, the mortality rate for the mother is around 1%, while the mortality rate for the baby ranges from 5-10%, depending on the gestational age at the time of delivery.

Brown or reddish-brown discharge, which is commonly known as spotting, typically indicates the presence of blood in the fluid. It is important to approach any postmenopausal bleeding as a potential malignancy until proven otherwise.

When investigating cases of postmenopausal bleeding, the first-line examination is a transvaginal ultrasound (TVUS). This method effectively assesses the risk of endometrial cancer by measuring the thickness of the endometrium.

In postmenopausal women, the average endometrial thickness is significantly thinner compared to premenopausal women. The likelihood of endometrial cancer increases as the endometrium becomes thicker. In current practice in the UK, an endometrial thickness of 5 mm is considered the threshold.

If the endometrial thickness exceeds 5 mm, there is a 7.3% chance of endometrial cancer. However, if the endometrial thickness is uniformly less than 5 mm in a woman with postmenopausal bleeding, the likelihood of endometrial cancer is less than 1%.

In cases where there is a clinical suspicion of high risk, hysteroscopy and endometrial biopsy should also be performed. The definitive diagnosis is made through histological examination. If the endometrial thickness exceeds 5 mm, an endometrial biopsy is recommended.

Anti-D is an antibody of the IgG class that targets the Rhesus D (RhD) antigen. It is specifically administered to women who are RhD negative, meaning they do not have the RhD antigen on their red blood cells. When a RhD negative woman is exposed to the blood of a RhD positive fetus, she may develop antibodies against RhD that can cross the placenta and attack the red blood cells of the fetus, leading to a condition called hemolytic disease of the newborn. Anti-D is given to bind to the fetal red blood cells in the mother’s circulation and neutralize them before an immune response is triggered.

RhD should be administered in the event of a sensitizing event, which can include childbirth, antepartum hemorrhage, miscarriage, ectopic pregnancy, intrauterine death, amniocentesis, chorionic villus sampling, or abdominal trauma. It is important to administer Anti-D as soon as possible after a sensitizing event, but it can still provide some benefit even if given outside of the recommended 72-hour window, according to the British National Formulary (BNF).

For RhD negative women, routine antenatal prophylaxis with Anti-D is recommended at 28 and 34 weeks of pregnancy, regardless of whether they have already received Anti-D earlier in the same pregnancy due to a sensitizing event.

In cases of uncomplicated miscarriage before 12 weeks of gestation, confirmed by ultrasound, or mild and painless vaginal bleeding, prophylactic Anti-D is not necessary because the risk of feto-maternal hemorrhage is extremely low. However, in cases of therapeutic termination of pregnancy, whether through surgical or medical methods, confirmed RhD negative women who are not known to be sensitized to RhD should receive 250 IU of prophylactic Anti-D immunoglobulin.

The most recent guidelines from the National Institute for Health and Care Excellence (NICE) recommend using a LNG-IUS, such as Mirena IUS, as the initial treatment for heavy menstrual bleeding (HMB) in women who have no identified pathology, fibroids smaller than 3 cm without uterine cavity distortion, or suspected/diagnosed adenomyosis. If a woman declines or cannot use an LNG-IUS, alternative pharmacological treatments can be considered. These include non-hormonal options like Tranexamic acid or NSAIDs, as well as hormonal options like combined hormonal contraception or cyclical oral progestogens. to the NICE guidelines on the assessment and management of heavy menstrual bleeding.

When administering CPR to a pregnant patient, it is important to make certain modifications. Firstly, the hand position for chest compressions should be adjusted to be 2-3 cm higher than usual. Additionally, the uterus should be manually displaced to the left in order to minimize compression on the inferior vena cava. If possible, a 15-30 degree left lateral tilt should be implemented. If resuscitation efforts do not result in the return of spontaneous circulation, it is advisable to seek urgent obstetric input for potential consideration of a C-section delivery. Lastly, when inserting an ET tube, it may be necessary to use a size that is 0.5-1.0mm smaller due to potential narrowing of the trachea caused by edema.

Cardiopulmonary arrest is a serious event with low survival rates. In non-traumatic cardiac arrest, only about 20% of patients who arrest as an in-patient survive to hospital discharge, while the survival rate for out-of-hospital cardiac arrest is approximately 8%. The Resus Council BLS/AED Algorithm for 2015 recommends chest compressions at a rate of 100-120 per minute with a compression depth of 5-6 cm. The ratio of chest compressions to rescue breaths is 30:2.

After a cardiac arrest, the goal of patient care is to minimize the impact of post cardiac arrest syndrome, which includes brain injury, myocardial dysfunction, the ischaemic/reperfusion response, and the underlying pathology that caused the arrest. The ABCDE approach is used for clinical assessment and general management. Intubation may be necessary if the airway cannot be maintained by simple measures or if it is immediately threatened. Controlled ventilation is aimed at maintaining oxygen saturation levels between 94-98% and normocarbia. Fluid status may be difficult to judge, but a target mean arterial pressure (MAP) between 65 and 100 mmHg is recommended. Inotropes may be administered to maintain blood pressure. Sedation should be adequate to gain control of ventilation, and short-acting sedating agents like propofol are preferred. Blood glucose levels should be maintained below 8 mmol/l. Pyrexia should be avoided, and there is some evidence for controlled mild hypothermia but no consensus on this.

Post ROSC investigations may include a chest X-ray, ECG monitoring, serial potassium and lactate measurements, and other imaging modalities like ultrasonography, echocardiography, CTPA, and CT head, depending on availability and skills in the local department. Treatment should be directed towards the underlying cause, and PCI or thrombolysis may be considered for acute coronary syndrome or suspected pulmonary embolism, respectively.

Patients who are comatose after ROSC without significant pre-arrest comorbidities should be transferred to the ICU for supportive care. Neurological outcome at 72 hours is the best prognostic indicator of outcome.

This patient is experiencing vaginal bleeding along with bradycardia and hypotension. These symptoms can be attributed to a condition known as cervical shock syndrome. It is likely that the products of conception (POC) are located within the os. In cervical shock syndrome, the cervix becomes dilated due to the presence of POC, leading to an increase in bleeding and triggering a vasovagal reaction.

To address this situation, it is crucial to conduct an urgent speculum examination. During this examination, the POC should be carefully removed using sterile sponge forceps.

Pelvic inflammatory disease (PID) is an infection that affects the upper female reproductive tract, including the uterus, fallopian tubes, and ovaries. It is typically caused by an ascending infection from the cervix. The most common culprits are sexually transmitted diseases like chlamydia and gonorrhea, with chlamydia being the most prevalent infection seen in UK genitourinary medicine clinics.

PID can often be asymptomatic, but when symptoms do occur, they may include lower abdominal pain and tenderness, fever, painful urination, painful intercourse, purulent vaginal discharge, abnormal vaginal bleeding, and tenderness in the cervix and adnexa. It’s important to note that symptoms of ectopic pregnancy can be mistaken for PID, so a pregnancy test should always be conducted in patients with suspicious symptoms.

To investigate a potential case of PID, endocervical swabs are taken to test for chlamydia and gonorrhea using nucleic acid amplification tests. It is recommended to start empirical antibiotic treatment as soon as a presumptive diagnosis of PID is made, without waiting for swab results.

Mild to moderate cases of PID can usually be managed in primary care or outpatient settings. However, patients with severe disease should be admitted to the hospital for intravenous antibiotics. Signs of severe disease include a fever above 38°C, signs of a tubo-ovarian abscess, signs of pelvic peritonitis, or concurrent pregnancy.

The current recommended treatment for outpatient cases of PID is a single intramuscular dose of ceftriaxone 500 mg, followed by oral doxycycline 100 mg twice daily and oral metronidazole 400 mg twice daily for 14 days. An alternative regimen is oral ofloxacin 400 mg twice daily and oral metronidazole 400 mg twice daily for 14 days.

For severely ill patients in the inpatient setting, initial treatment consists of intravenous doxycycline, a single-dose of intravenous ceftriaxone, and intravenous metronidazole. Afterward, the treatment is switched to oral doxycycline and metronidazole to complete a 14-day course.

This patient is highly likely to have developed a tubo-ovarian abscess (TOA), which is a complication of pelvic inflammatory disease. TOA occurs when a pocket of pus forms in the fallopian tube and/or ovary. If the abscess ruptures, it can lead to sepsis and become life-threatening.

The initial imaging modality of choice is transabdominal and endovaginal ultrasound. This imaging technique often reveals multilocular complex retro-uterine/adnexal masses with debris, septations, and irregular thick walls. These masses can be present on both sides.

Urgent hospital admission is necessary, and the usual management involves draining the abscess and administering intravenous antibiotics. The abscess drainage can be guided by ultrasound or CT scanning.

In some cases, laparotomy or laparoscopy may be required to drain the abscess.

An incomplete miscarriage occurs when a miscarriage occurs, but the products of conception have not been fully expelled from the uterus. This commonly happens between weeks 8 and 14 of pregnancy.

Symptoms of an incomplete miscarriage include pain and bleeding, and the cervix is usually open. A diagnosis can be confirmed through an ultrasound scan, which will show the absence of a fetal heartbeat and retained products.

Treatment for an incomplete miscarriage can be done medically, such as using misoprostol, or surgically, like undergoing an ERPC procedure.

There are potential complications that can arise from an incomplete miscarriage, including endometritis, myometritis, septic shock, and disseminated intravascular coagulation (DIC).

Cardiac arrest during pregnancy is a rare occurrence, happening in approximately 16 out of every 100,000 live births. It is crucial to consider both the mother and the fetus when dealing with cardiac arrest in pregnancy, as the best way to ensure a positive outcome for the fetus is by effectively resuscitating the mother.

The main causes of cardiac arrest during pregnancy include pre-existing cardiac disease, pulmonary embolism, hemorrhage, ectopic pregnancy, hypertensive disorders of pregnancy, amniotic fluid embolism, and suicide. Many cardiovascular problems associated with pregnancy are caused by compression of the inferior vena cava.

To prevent decompensation or potential cardiac arrest during pregnancy, it is important to follow these steps when dealing with a distressed or compromised pregnant patient:

– Place the patient in the left lateral position or manually displace the uterus to the left.
– Administer high-flow oxygen, guided by pulse oximetry.
– Give a fluid bolus if there is low blood pressure or signs of hypovolemia.
– Re-evaluate the need for any medications currently being administered.
– Seek expert help and involve obstetric and neonatal specialists early.
– Identify and treat the underlying cause.

In the event of cardiac arrest during pregnancy, in addition to following the standard guidelines for basic and advanced life support, the following modifications should be made:

– Immediately call for expert help, including an obstetrician, anesthetist, and neonatologist.
– Start CPR according to the standard ALS guidelines, but adjust the hand position slightly higher on the sternum.
– Ideally establish IV or IO access above the diaphragm to account for potential compression of the inferior vena cava.
– Manually displace the uterus to the left to relieve caval compression.
– Tilt the table to the left side (around 15-30 degrees of tilt).
– Perform early tracheal intubation to reduce the risk of aspiration (seek assistance from an expert anesthetist).
– Begin preparations for an emergency Caesarean section.

A perimortem Caesarean section should be performed within 5 minutes of the onset of cardiac arrest. This delivery will alleviate caval compression and increase the chances of successful resuscitation by improving venous return during CPR. It will also maximize the chances of the infant’s survival, as the best survival rate occurs when delivery is achieved within 5 minutes of the mother’s cardiac arrest.

An ectopic pregnancy happens when the fertilized egg attaches itself outside of the uterus. In over 95% of cases, ectopic pregnancies occur in the Fallopian tubes. Although rare, they can also occur in other locations such as the abdomen, cervix, and ovary.

The most common location for an ectopic pregnancy in the Fallopian tube is the ampulla, accounting for approximately 70% of cases. The isthmus and infundibulum each account for 10-15% of cases, while the uterine part only accounts for 2-5%.

Varicella can have serious consequences for pregnant women. If a woman contracts varicella during the first 28 weeks of pregnancy, there is a 1% chance that the fetus will be affected and develop foetal varicella syndrome (FVS). FVS is characterized by eye defects, limb underdevelopment, skin scarring, and neurological abnormalities.

Pregnant women who have not had chickenpox or who test negative for VZV IgG should be advised to minimize contact with individuals who have chickenpox or shingles. If they are exposed, they should seek immediate medical help.

If a pregnant woman is exposed to varicella, the first step is to perform a blood test to check for VZV immunity. If she is not immune and the exposure is significant, she should be given VZV immunoglobulin as soon as possible. This treatment is effective within 10 days of exposure.

If a pregnant woman develops chickenpox, she should urgently seek medical assistance. There is an increased risk of pneumonia, encephalitis, and hepatitis for the mother, as well as a 1% risk of the fetus developing FVS.

Acyclovir should be used cautiously before 20 weeks of gestation but is recommended after 20 weeks if the woman seeks medical help within 24 hours of the rash appearing.

If a woman develops any complications of varicella, she must be referred to a hospital. Additionally, she should be referred to a specialized center five weeks after the infection for a detailed ultrasound scan to determine if FVS has occurred.

For more information, refer to the Royal College of Obstetricians and Gynaecologists green-top guidelines for the management of VZV exposure and infection in pregnancy.

The primary reason for foetal death in trauma during pregnancy is maternal shock and maternal mortality. The second most prevalent cause of foetal death is placental abruption.

Pregnant women who contract chickenpox for the first time are more likely to develop pneumonitis, a condition characterized by inflammation of the lungs. Additionally, these women face a five-fold increased risk of pneumonitis compared to non-pregnant individuals. Furthermore, the fetus is at risk of developing fetal varicella syndrome, a condition associated with chickenpox infection during pregnancy.

Further Reading:

Chickenpox exposure during pregnancy poses risks to both the mother and the fetus. The mother has a 5 times greater risk of developing pneumonitis, a potentially serious complication. The fetus is at risk of developing fetal varicella syndrome (FVS) if the maternal exposure occurs before 20 weeks gestation. The risk of FVS is around 1% in these cases and includes features such as skin scarring, eye defects, limb hypoplasia, microcephaly, and learning disabilities. There have been very few cases of FVS reported between 20-28 weeks gestation and none following 28 weeks.

Other risks to the fetus include the development of shingles in infancy, which has a 1-2% risk if the maternal exposure occurs in the second or third trimester. There is also a risk of severe neonatal varicella if the mother develops a rash between 5 days before and 2 days after birth. This condition can be fatal to the newborn child in around 20% of cases.

In the management of chickenpox exposure during pregnancy, it is important to determine if the mother is immune to varicella. If there is any doubt, maternal blood should be urgently checked for varicella antibodies. If the pregnant woman is not immune, she should be given varicella zoster immunoglobulin (VZIG) as soon as possible. VZIG is considered effective up to 10 days post-exposure. Consensus guidelines also recommend the use of oral aciclovir if the pregnant woman presents with chickenpox within 24 hours of the rash onset.

Cardiac arrest during pregnancy is a rare occurrence, happening in approximately 16 out of every 100,000 live births.

Sheehan’s syndrome is a condition where the pituitary gland becomes damaged due to insufficient blood flow and shock during and after childbirth, leading to hypopituitarism. The risk of developing this syndrome is higher in pregnancies with conditions that increase the chances of bleeding, such as placenta praevia and multiple pregnancies. Sheehan’s syndrome is quite rare, affecting only 1 in 10,000 pregnancies.

During pregnancy, the anterior pituitary gland undergoes hypertrophy, making it more vulnerable to ischaemia in the later stages. While the posterior pituitary gland is usually unaffected due to its direct arterial supply, there have been rare cases where it is also involved.

The clinical features of Sheehan’s syndrome include the absence or infrequency of menstrual periods, the inability to produce milk and breastfeed (galactorrhoea), decreased libido, fatigue and tiredness, and loss of pubic and axillary hair. Additionally, secondary hypothyroidism and adrenal insufficiency may also occur.

Serum prolactin levels are typically low, measuring less than 5ng/ml. An MRI can be helpful in ruling out other pituitary issues, such as a pituitary tumor.

The management of Sheehan’s syndrome involves hormone replacement therapy. With appropriate treatment, the prognosis for this condition is excellent.

Pelvic inflammatory disease (PID) is a pelvic infection that affects the upper female reproductive tract, including the uterus, fallopian tubes, and ovaries. It is typically caused by an ascending infection from the cervix and is commonly associated with sexually transmitted diseases like chlamydia and gonorrhea. In the UK, genital Chlamydia trachomatis infection is the most common cause of PID seen in genitourinary medicine clinics.

PID can often be asymptomatic, but when symptoms are present, they may include lower abdominal pain and tenderness, fever, painful urination, painful intercourse, purulent vaginal discharge, abnormal vaginal bleeding, and tenderness in the cervix and adnexa. It is important to note that symptoms of ectopic pregnancy can be similar to those of PID, so a pregnancy test should be conducted for all patients with suspicious symptoms.

To investigate a possible case of PID, endocervical swabs should be taken to test for C. trachomatis and N. gonorrhoeae using nucleic acid amplification tests if available. Mild to moderate cases of PID can usually be managed in primary care or outpatient settings, while patients with severe disease should be admitted to the hospital for intravenous antibiotics. Signs of severe disease include a fever above 38°C, signs of a tubo-ovarian abscess, signs of pelvic peritonitis, or concurrent pregnancy.

Empirical antibiotic treatment should be initiated as soon as a presumptive diagnosis of PID is made clinically, without waiting for swab results. The current recommended outpatient treatment for PID is a single intramuscular dose of ceftriaxone 500 mg, followed by oral doxycycline 100 mg twice daily and oral metronidazole 400 mg twice daily for 14 days. An alternative regimen is oral ofloxacin 400 mg twice daily and oral metronidazole 400 mg twice daily for 14 days.

For severely ill patients in the inpatient setting, initial treatment includes intravenous doxycycline, a single-dose of intravenous ceftriaxone, and intravenous metronidazole. This is then followed by a switch to oral doxycycline and metronidazole to complete a 14-day treatment course. If a patient fails to respond to treatment, laparoscopy is necessary to confirm the diagnosis or consider alternative diagnoses.

Uterine rupture can occur in two forms: primary, which happens without any previous uterine surgery or trauma, and secondary, which occurs when there is scar dehiscence. In secondary rupture, the rupture can range from the peritoneum to the endometrium, or the peritoneum may remain intact while the underlying uterine tissue ruptures.

There are several risk factors associated with uterine rupture, including multiparity, a uterine scar from a previous Caesarean section, previous uterine surgery, dysfunctional labor, and augmented labor with medications like oxytocin or prostaglandins.

The clinical features of uterine rupture include abdominal pain and tenderness, abdominal guarding and rigidity, inability to feel the uterine fundus (in cases of fundal rupture), cessation of uterine contractions, chest pain or shoulder tip pain, vaginal bleeding, abnormal fetal lie (such as oblique or transverse), easy palpation of fetal parts outside the uterus, absent fetal heart sounds, and abnormal CTG findings like late decelerations and reduced variability. Maternal shock can also occur and may be severe.

Immediate resuscitation is crucial and should involve intravenous fluids and/or blood transfusion. This should be followed by a laparotomy. After the baby is delivered, the uterus should be repaired or a hysterectomy may be performed. The decision between these two management options depends on factors such as the site and extent of the rupture, as well as the mother’s condition, age, and parity.

The Zika virus is a newly emerging virus that is transmitted by mosquitoes. It was first discovered in humans in Uganda in 1952. Recently, there has been a significant outbreak of the virus in South America.

When a person contracts the Zika virus, about 1 in 5 individuals will experience clinical illness, while the rest will show no symptoms at all. The most common symptoms of the virus include fever, rash, joint pain, and conjunctivitis. These symptoms typically last for no more than a week.

While not completely conclusive, the evidence from the recent outbreak strongly suggests a connection between Zika virus infection and microcephaly.

HELLP syndrome is a condition that occurs in approximately 0.5% of pregnancies. It is characterized by haemolysis, elevated liver enzymes, and a low platelet count. While it typically occurs in the late third trimester, it has also been reported in the late second trimester. Around 33% of patients with HELLP syndrome will present shortly after giving birth.

The initial symptoms of HELLP syndrome can be vague and include nausea, headaches, malaise, and pain in the upper right quadrant of the abdomen. Upon examination, raised blood pressure, proteinuria, and edema may be observed. Further investigations may reveal haemolysis on a blood film, elevated liver enzymes, low platelets, raised LDH, and raised bilirubin.

Delivery of the baby is the main treatment for HELLP syndrome. However, complications can arise, such as disseminated intravascular coagulation (DIC), renal failure, liver failure, and pulmonary edema. It is crucial to tightly control blood pressure, and magnesium sulfate is often used to reduce the risk of progression to eclampsia. If DIC occurs, treatment with fresh frozen plasma is necessary.

Without prompt recognition, approximately 25% of individuals with HELLP syndrome may experience severe complications, including placental abruption, liver failure, retinal detachment, and renal failure. With treatment, the mortality rate for the mother is around 1%, while the mortality rate for the baby ranges from 5-10%, depending on the gestational age at the time of delivery.
