Nerve Damage in Obstetric and Surgical Procedures

During obstetric and surgical procedures, nerve damage can occur in various parts of the body. One such instance is a total vault prolapse, which can occur following a hysterectomy. Two surgical options for management include sacrocolpopexy and sacrospinous fixation. While sacrocolpopexy involves suturing the vaginal vault to the sacrum, sacrospinous fixation requires suturing the top of the vaginal vault to the sacrospinous ligament. However, complications such as damage to the sciatic nerve and pudendal vessels can occur with the latter procedure.

Damage to the common peroneal nerve is most common during total knee arthroplasties when the patient is placed in the lithotomy and lateral positions for extended periods of time. On the other hand, the femoral nerve can be injured during abdomino-pelvic surgery, aortic cross-clamp, invasive procedures to access the femoral vessels, and hip arthroplasty. Inguinal hernia repair is the most common cause of damage to the inguinal nerve.

Lastly, isolated damage to the posterior cutaneous nerve of the thigh is not associated with obstetric surgery. However, damage to the main femoral nerve is commonly seen in abdominal hysterectomies due to compression by retractor blades. It is important for healthcare professionals to be aware of these potential complications and take necessary precautions to prevent nerve damage during procedures.

Treatment Options for Infertility in Women with PCOS

Polycystic ovary syndrome (PCOS) is a common cause of infertility in women. Clomiphene citrate is the first-line medication used to induce ovulation in women with PCOS who wish to conceive. It works by binding to hypothalamic estrogen receptors, inhibiting the negative feedback on follicle-stimulating hormone (FSH) and triggering ovulation. However, it is important to counsel women about the increased risk of multiple pregnancy when treated with Clomiphene. Metformin, once considered a viable option for PCOS-related infertility, is now considered inferior to Clomiphene. However, it can be used in combination with Clomiphene to increase the success of ovulation induction. Gonadotrophins are recommended as second-line treatment for women who do not respond to Clomiphene. Laparoscopic ovarian drilling is a surgical option reserved for cases where Clomiphene has failed. It involves destroying ovarian stroma to reduce androgen-secreting tissue and induce ovulation. The choice of treatment depends on individual patient factors and should be discussed with a healthcare provider.

Endometrial cancer is strongly linked to HNPCC/Lynch syndrome, while the use of combined oral contraceptives can help reduce the risk. Other factors that increase the risk of endometrial cancer include obesity, a higher number of ovulations (due to factors such as early menarche, late menopause, and fewer pregnancies), certain medications like tamoxifen, and medical conditions like diabetes and polycystic ovarian syndrome. Anorexia, the Mirena coil, and familial adenomatous polyposis are not considered risk factors for endometrial cancer.

Endometrial cancer is a type of cancer that is commonly found in women who have gone through menopause, but it can also occur in around 25% of cases before menopause. The prognosis for this type of cancer is usually good due to early detection. There are several risk factors associated with endometrial cancer, including obesity, nulliparity, early menarche, late menopause, unopposed estrogen, diabetes mellitus, tamoxifen, polycystic ovarian syndrome, and hereditary non-polyposis colorectal carcinoma. Postmenopausal bleeding is the most common symptom of endometrial cancer, which is usually slight and intermittent initially before becoming more heavy. Pain is not common and typically signifies extensive disease, while vaginal discharge is unusual.

When investigating endometrial cancer, women who are 55 years or older and present with postmenopausal bleeding should be referred using the suspected cancer pathway. The first-line investigation is trans-vaginal ultrasound, which has a high negative predictive value for a normal endometrial thickness (< 4 mm). Hysteroscopy with endometrial biopsy is also commonly used for investigation. The management of localized disease involves total abdominal hysterectomy with bilateral salpingo-oophorectomy, while patients with high-risk disease may have postoperative radiotherapy. progesterone therapy is sometimes used in frail elderly women who are not considered suitable for surgery. It is important to note that the combined oral contraceptive pill and smoking are protective against endometrial cancer.

It is safe to insert a contraceptive implant after childbirth. The manufacturer of the most commonly used implant in the UK, Nexplanon®, recommends waiting at least 4 weeks postpartum for breastfeeding women. While there is no evidence of harm to the mother or baby, it is not recommended to insert an implant during pregnancy due to potential complications. It may take some time for fertility to return after pregnancy.

Implanon and Nexplanon are subdermal contraceptive implants that slowly release the progesterone hormone etonogestrel to prevent ovulation and thicken cervical mucous. Nexplanon is the newer version and has a redesigned applicator to prevent deep insertions and is radiopaque for easier location. It is highly effective with a failure rate of 0.07/100 women-years and lasts for 3 years. It does not contain estrogen, making it suitable for women with a past history of thromboembolism or migraine. It can be inserted immediately after a termination of pregnancy. However, a trained professional is needed for insertion and removal, and additional contraceptive methods are required for the first 7 days if not inserted on days 1 to 5 of a woman’s menstrual cycle.

The main disadvantage of these implants is irregular and heavy bleeding, which can be managed with a co-prescription of the combined oral contraceptive pill. Other adverse effects include headache, nausea, and breast pain. Enzyme-inducing drugs such as certain antiepileptic and rifampicin may reduce the efficacy of Nexplanon, and women should switch to a method unaffected by enzyme-inducing drugs or use additional contraception until 28 days after stopping the treatment.

There are also contraindications for using these implants, such as ischaemic heart disease/stroke, unexplained, suspicious vaginal bleeding, past breast cancer, severe liver cirrhosis, and liver cancer. Current breast cancer is a UKMEC 4 condition, which represents an unacceptable risk if the contraceptive method is used. Overall, these implants are a highly effective and long-acting form of contraception, but they require careful consideration of the potential risks and contraindications.

The contraceptive implant primarily works by inhibiting ovulation through the slow release of progesterone hormone. While it also increases cervical mucous thickness, this is not its main mode of action. The progesterone-only pill also increases cervical mucous thickness, while the intrauterine copper device decreases sperm viability. The intrauterine system prevents implantation of the ovum by exerting local progesterone onto the uterine lining.

Understanding the Mode of Action of Contraceptives

Contraceptives are used to prevent unwanted pregnancies. They work by different mechanisms depending on the type of contraceptive used. The Faculty for Sexual and Reproductive Health (FSRH) has provided a table that outlines the mode of action of standard contraceptives and emergency contraception.

Standard contraceptives include the combined oral contraceptive pill, progesterone-only pill, injectable contraceptive, implantable contraceptive, and intrauterine contraceptive device/system. The combined oral contraceptive pill and injectable/implantable contraceptives primarily work by inhibiting ovulation, while the progesterone-only pill and some injectable/implantable contraceptives thicken cervical mucous to prevent sperm from reaching the egg. The intrauterine contraceptive device/system decreases sperm motility and survival and prevents endometrial proliferation.

Emergency contraception, which is used after unprotected sex or contraceptive failure, also works by different mechanisms. Levonorgestrel and ulipristal inhibit ovulation, while the intrauterine contraceptive device is toxic to sperm and ovum and inhibits implantation.

Understanding the mode of action of contraceptives is important in choosing the most appropriate method for an individual’s needs and preferences. It is also important to note that no contraceptive method is 100% effective, and the use of condoms can provide additional protection against sexually transmitted infections.

According to NICE guidelines, an endometrial biopsy should be performed if necessary to rule out endometrial cancer or atypical hyperplasia. The biopsy is recommended for women who experience persistent intermenstrual bleeding and for those aged 45 and above who have had unsuccessful or ineffective treatment. In the case of the patient mentioned above, her treatment has not been successful and she has a thickened endometrium. Although there is some debate about the thickness of the endometrium in premenopausal women, this patient qualifies for a biopsy based on her failed medical treatment alone, making it the most appropriate option.

The prognosis for this type of cancer is usually good due to early detection.

It is important to note that the combined oral contraceptive pill and smoking are protective against endometrial cancer.

Not all hormonal contraceptives are contraindicated for patients assigned female at birth undergoing testosterone therapy. The combined oral contraceptive pill, which contains oestrogen, should be avoided as it may interfere with the effects of testosterone therapy. However, the copper intrauterine device and progesterone-only pill are acceptable options as they do not have any adverse effects on testosterone therapy. The vaginal ring, which also contains oestrogen, should also be avoided.

Contraceptive and Sexual Health Guidance for Transgender and Non-Binary Individuals

The Faculty of Sexual & Reproductive Healthcare has released guidance on contraceptive choices and sexual health for transgender and non-binary individuals. The guidance emphasizes the importance of sensitive communication and offering options that consider personal preferences, co-morbidities, and current medications or therapies.

For individuals engaging in vaginal sex where there may be a risk of pregnancy and/or sexually transmitted infections, condoms and dental dams are recommended. Cervical screening and human papillomavirus vaccinations should also be offered to sexually active individuals with a uterus. Those engaging in anal sex and rimming should be advised of the risk of hepatitis A & B and offered vaccinations. Individuals at risk of HIV transmission should be advised of the availability of pre-exposure prophylaxis and post-exposure prophylaxis as required.

For patients seeking permanent contraception, a fallopian tube occlusion or a vasectomy may be the most appropriate solution and neither would be affected by hormonal therapy. Testosterone therapy does not provide protection against pregnancy, and oestrogen-containing regimes are not recommended in patients undergoing testosterone therapy. Progesterone-only contraceptives are considered safe, and the intrauterine system and injections may also suspend menstruation. Non-hormonal intrauterine devices do not interact with hormonal regimes but can exacerbate menstrual bleeding.

In patients assigned male at birth, there may be a reduction or cessation of sperm production with certain therapies, but the variability of effects means they cannot be relied upon as a method of contraception. Condoms should be recommended in those patients engaging in vaginal sex wishing to avoid the risk of pregnancy. Emergency contraception may be required in patients assigned female at birth following unprotected vaginal intercourse, and either of the available oral emergency contraceptive options may be considered. The non-hormonal intrauterine device may also be an option, but it may have unacceptable side effects in some patients.

Overall, the guidance stresses the importance of individualized care and communication in contraceptive and sexual health decisions for transgender and non-binary individuals.

For a patient who has had unprotected intercourse within the last 72 hours and is seeking the most effective form of emergency contraception, the recommended course of action is to arrange for a copper coil (IUD) insertion. This method is effective for up to five days (120 hours) after intercourse, whether or not ovulation has occurred, and works by preventing fertilization or implantation. If there are concerns about sexually transmitted infections, antibiotics can be given at the same time. It is incorrect to advise the patient that she has missed the window for emergency contraception, as both the copper coil and ulipristal acetate are licensed for use up to five days after intercourse, while levonorgestrel emergency contraception can be taken up to 72 hours after. Prescribing levonorgestrel emergency contraception would not be the best option in this case, as its efficacy decreases with time and it is minimally effective if ovulation has already occurred. Similarly, ulipristal acetate may be less effective if ovulation has already occurred, so a copper coil insertion would be a more appropriate choice.

Emergency contraception is available in the UK through two methods: emergency hormonal contraception and intrauterine device (IUD). Emergency hormonal contraception includes two types of pills: levonorgestrel and ulipristal. Levonorgestrel works by stopping ovulation and inhibiting implantation, while ulipristal primarily inhibits ovulation. Levonorgestrel should be taken as soon as possible after unprotected sexual intercourse, within 72 hours, and is 84% effective when used within this time frame. The dose should be doubled for those with a BMI over 26 or weight over 70kg. Ulipristal should be taken within 120 hours of intercourse and may reduce the effectiveness of hormonal contraception. The most effective method of emergency contraception is the copper IUD, which can be inserted within 5 days of unprotected intercourse or up to 5 days after the likely ovulation date. It may inhibit fertilization or implantation and is 99% effective regardless of where it is used in the cycle. Prophylactic antibiotics may be given if the patient is at high risk of sexually transmitted infection.

Possible Diagnoses for Abdominal Pain in Women of Childbearing Age

One of the most likely diagnoses for a woman of childbearing age presenting with abdominal pain is a ruptured ectopic pregnancy. This is especially true if the patient has a history of using an intrauterine device (IUD), has missed a period, and experiences scanty bleeding. However, other possible differential diagnoses include appendicitis, ovarian cysts, and pelvic inflammatory disease.

Appendicitis may cause right iliac fossa pain, but the other symptoms and history suggest an ectopic pregnancy as a more likely cause. A femoral hernia is inconsistent with the clinical findings. Ovarian cysts may also cause right iliac fossa pain, but the other features from the history point to an ectopic pregnancy as a more likely cause. Pelvic inflammatory disease is not consistent with the history described, as there is no offensive discharge and no sexual history provided. Additionally, pelvic inflammatory disease does not cause a delay in the menstrual period.

It is important to always test for pregnancy in any woman of childbearing age presenting with abdominal pain, regardless of contraception use or perceived likelihood of pregnancy. Early diagnosis and treatment of a ruptured ectopic pregnancy can be life-saving.
