The FSRH uses a scale of 1 to 4 to categorize risk factors for contraceptive methods. A rating of 1 indicates no restrictions on use, while a rating of 4 indicates a condition that poses an unacceptable risk if the contraceptive method is used. Migraine with aura is the only absolute contraindication among the answer options. Ratings of 2 and 3 indicate that the advantages and risks of the contraceptive method should be carefully considered and evaluated by a clinical expert.

The decision to prescribe the combined oral contraceptive pill is now based on the UK Medical Eligibility Criteria (UKMEC), which categorizes potential contraindications and cautions on a four-point scale. UKMEC 1 indicates no restrictions for use, while UKMEC 2 suggests that the benefits outweigh the risks. UKMEC 3 indicates that the disadvantages may outweigh the advantages, and UKMEC 4 represents an unacceptable health risk. Examples of UKMEC 3 conditions include controlled hypertension, a family history of thromboembolic disease in first-degree relatives under 45 years old, and current gallbladder disease. Examples of UKMEC 4 conditions include a history of thromboembolic disease or thrombogenic mutation, breast cancer, and uncontrolled hypertension. Diabetes mellitus diagnosed over 20 years ago is classified as UKMEC 3 or 4 depending on severity. In 2016, breast feeding between 6 weeks and 6 months postpartum was changed from UKMEC 3 to UKMEC 2.

The Barlow manoeuvre is a technique used to try and dislocate a newborn’s femoral head. If successful, the Ortolani manoeuvre can then be used to relocate the dislocated femoral head. The Thomas test is not appropriate for neonates and is used to identify hip flexion contractures in older patients. The Denis Brown bar is an orthotic device used in conjunction with the Ponseti method to correct a fixed talipes.

Developmental dysplasia of the hip (DDH) is a condition that affects 1-3% of newborns and is more common in females, firstborn children, and those with a positive family history or breech presentation. It used to be called congenital dislocation of the hip (CDH). DDH is more often found in the left hip and can be bilateral in 20% of cases. Screening for DDH is recommended for infants with certain risk factors, and all infants are screened using the Barlow and Ortolani tests at the newborn and six-week baby check. Clinical examination includes testing for leg length symmetry, restricted hip abduction, and knee level when hips and knees are flexed. Ultrasound is used to confirm the diagnosis if clinically suspected, but x-ray is the first line investigation for infants over 4.5 months. Management includes the use of a Pavlik harness for children under 4-5 months and surgery for older children with unstable hips.

When a patient presents with a facial nerve palsy and a vesicular rash, Ramsay Hunt syndrome should be considered. The vesicles may not be limited to the ear canal and can also appear on the tongue or soft palate. Treatment typically involves administering oral aciclovir and corticosteroids, unless the patient is severely ill. Ganciclovir is used to treat cytomegalovirus, while amoxicillin would be a more suitable option if bacterial otitis media was the underlying cause of the patient’s symptoms.

Understanding Ramsay Hunt Syndrome

Ramsay Hunt syndrome, also known as herpes zoster oticus, is a condition that occurs when the varicella zoster virus reactivates in the geniculate ganglion of the seventh cranial nerve. The first symptom of this condition is often auricular pain, followed by facial nerve palsy and a vesicular rash around the ear. Other symptoms may include vertigo and tinnitus.

To manage Ramsay Hunt syndrome, doctors typically prescribe oral aciclovir and corticosteroids. These medications can help reduce the severity of symptoms and prevent complications.

Different Types of Lung Diseases and their Spirometry Patterns

Scoliosis and Lung Function
Severe scoliosis can affect the respiratory muscles and the natural movements of the thoracic cage, leading to a restrictive pattern in pulmonary function tests. This can prevent the lungs from expanding correctly, compromising their function.

Cystic Fibrosis and Lung Function
In early stage cystic fibrosis, the presence of inflammation and thick secretions in the airways can cause an obstructive pattern in spirometry tests. As damage to the lung tissue occurs, a restrictive component can also develop, resulting in a combined obstructive and restrictive pattern.

Emphysema and Lung Function
Emphysema is a type of obstructive lung disease characterized by abnormal and irreversible enlargement of air spaces and alveolar wall destruction. This leads to airflow limitation and a spirometry pattern typical of obstructive lung disease.

Asthma and Lung Function
Asthma is an inflammatory disorder of the airways that causes hyperresponsiveness and constriction of the airways in response to various stimuli. This leads to airflow limitation and a spirometry pattern typical of obstructive lung disease.

Bronchiectasis and Lung Function
Bronchiectasis is characterized by abnormal and irreversible dilatation of the bronchial walls, leading to accumulation of secretions and recurrent inflammation of the airways. This produces an obstructive pattern in pulmonary function tests.

In summary, different types of lung diseases can affect lung function in various ways, leading to different spirometry patterns. Understanding these patterns can help in the diagnosis and management of these conditions.

Sertraline is the recommended first-line medication for treating generalised anxiety disorder (GAD). This patient exhibits typical symptoms of GAD and has already undergone step 1 and step 2 of treatment without improvement. Therefore, she requires step 3, which involves either high-intensity psychological intervention or drug treatment. As the patient prefers drug treatment, sertraline is the appropriate choice as it is the most cost-effective SSRI for GAD according to NICE guidelines. Citalopram and fluoxetine are also SSRIs that may be used as second-line treatments if sertraline is not effective or tolerated. Diazepam, a benzodiazepine, is not recommended for GAD due to the risk of dependence, except in short-term crisis situations.

Anxiety is a common disorder that can manifest in various ways. According to NICE, the primary feature is excessive worry about multiple events associated with heightened tension. It is crucial to consider potential physical causes when diagnosing anxiety disorders, such as hyperthyroidism, cardiac disease, and medication-induced anxiety. Medications that may trigger anxiety include salbutamol, theophylline, corticosteroids, antidepressants, and caffeine.

NICE recommends a step-wise approach for managing generalised anxiety disorder (GAD). This includes education about GAD and active monitoring, low-intensity psychological interventions, high-intensity psychological interventions or drug treatment, and highly specialist input. Sertraline is the first-line SSRI for drug treatment, and if it is ineffective, an alternative SSRI or a serotonin-noradrenaline reuptake inhibitor (SNRI) such as duloxetine or venlafaxine may be offered. If the patient cannot tolerate SSRIs or SNRIs, pregabalin may be considered. For patients under 30 years old, NICE recommends warning them of the increased risk of suicidal thinking and self-harm and weekly follow-up for the first month.

The management of panic disorder also follows a stepwise approach, including recognition and diagnosis, treatment in primary care, review and consideration of alternative treatments, review and referral to specialist mental health services, and care in specialist mental health services. NICE recommends either cognitive behavioural therapy or drug treatment in primary care. SSRIs are the first-line drug treatment, and if contraindicated or no response after 12 weeks, imipramine or clomipramine should be offered.

Iliotibial band syndrome is a prevalent reason for knee pain, especially among runners. A typical history and examination for this condition involves assessing lateral knee pain in avid runners. In contrast, Osgood-Schlatter disease, also known as tibial apophysitis, would result in pain and swelling around the tibial tubercle. Osteochondritis dissecans would cause joint locking, swelling, and tenderness. Patellar tendonitis would also cause post-exercise pain, but it would typically be located at the lower part of the patella.

Understanding Iliotibial Band Syndrome

Iliotibial band syndrome is a prevalent condition that causes lateral knee pain in runners. It affects approximately 10% of people who engage in regular running. The condition is characterized by tenderness 2-3 cm above the lateral joint line.

To manage iliotibial band syndrome, activity modification and iliotibial band stretches are recommended. These measures can help alleviate the pain and discomfort associated with the condition. However, if the symptoms persist, it is advisable to seek physiotherapy referral for further assessment and treatment.

In summary, iliotibial band syndrome is a common condition that affects runners. It is important to recognize the symptoms and seek appropriate management to prevent further complications. With the right treatment, individuals can continue to engage in running and other physical activities without experiencing pain and discomfort.

Immediate Treatment for Serious Bleeding in Patients with Haemophilia

Serious or life-threatening bleeding in patients with haemophilia requires immediate evaluation and therapy with replacement factor. The immediate goal is to raise the activity of the deficient factor to a level sufficient to achieve haemostasis. For patients with potentially serious or life-threatening bleeding, treatment should be initiated immediately, even before completing diagnostic assessment.

In the case of haemophilia A, factor VIII must be replaced. Waiting to find out factor VIII levels prior to administering it could lead to further bleeding. Therefore, immediate administration of factor VIII is the most appropriate option.

While obtaining imaging of the head may be useful, the main objective is to obtain rapid haemostasis. Thus, transferring the patient immediately for a CT scan of the head is not the first action to take.

In a patient with haemophilia, evacuation of a clot may lead to further potentially catastrophic bleeding. If surgery is required, the patient must have adequate levels of factor VIII present to achieve haemostasis. Therefore, transferring the patient to the theatre for evacuation of an intracranial haematoma should not be the first action taken.

Hormone replacement therapy (HRT) is a treatment that involves administering synthetic oestrogen and progestogen to women experiencing menopausal symptoms. HRT can be given as local (creams, pessaries, rings) or systemic therapy (oral drugs, transdermal patches and gels, implants) and may contain oestrogen alone, combined oestrogen and progestogen, selective oestrogen receptor modulator, or gonadomimetics. The average age for menopause is around 50-51 years, and symptoms include hot flushes, insomnia, weight gain, mood changes, and irregular menses. HRT should be initiated at the lowest possible dosage and titrated based on clinical response. However, HRT is not recommended for women who have undergone hysterectomy due to the risk of endometrial hyperplasia, a precursor to endometrial cancer. HRT may also increase the risk of breast cancer and heart attacks, and non-hormonal options should be considered for menopausal effects in women who have previously had breast cancer. There is no evidence to suggest that HRT is associated with an increased or decreased risk of developing cervical cancer, and observational studies of systemic HRT after breast cancer are generally reassuring. Oestrogen is believed to be a growth factor that enhances cholinergic neurotransmission and prevents oxidative cell damage, neuronal atrophy, and glucocorticoid-induced neuronal damage, which may help prevent dementia.

The M rule for primary biliary cholangitis includes the presence of IgM and anti-Mitochondrial antibodies, specifically the M2 subtype, in middle-aged women.

Primary Biliary Cholangitis: A Chronic Liver Disorder

Primary biliary cholangitis, previously known as primary biliary cirrhosis, is a chronic liver disorder that is commonly observed in middle-aged women. The exact cause of this condition is not yet fully understood, but it is believed to be an autoimmune disease. The disease is characterized by the progressive damage of interlobular bile ducts due to chronic inflammation, leading to cholestasis and eventually cirrhosis. The most common symptom of primary biliary cholangitis is itching in middle-aged women.

This condition is often associated with other autoimmune diseases such as Sjogren’s syndrome, rheumatoid arthritis, systemic sclerosis, and thyroid disease. Early symptoms of primary biliary cholangitis may be asymptomatic or may include fatigue, pruritus, and cholestatic jaundice. Late symptoms may progress to liver failure. Diagnosis of primary biliary cholangitis involves immunology tests such as anti-mitochondrial antibodies (AMA) M2 subtype and smooth muscle antibodies, as well as imaging tests to exclude an extrahepatic biliary obstruction.

The first-line treatment for primary biliary cholangitis is ursodeoxycholic acid, which slows down the progression of the disease and improves symptoms. Cholestyramine is used to alleviate pruritus, and fat-soluble vitamin supplementation is recommended. In severe cases, liver transplantation may be necessary, especially if bilirubin levels exceed 100. However, recurrence in the graft can occur, but it is not usually a problem. Complications of primary biliary cholangitis include cirrhosis, portal hypertension, ascites, variceal hemorrhage, osteomalacia, osteoporosis, and an increased risk of hepatocellular carcinoma.

The most likely diagnosis for this patient’s gradual central loss of vision and difficulty reading is dry age-related macular degeneration. This subtype accounts for the majority of cases of macular degeneration and typically presents with a gradual loss of vision. Glaucoma and retinal detachment are unlikely diagnoses as they present with different symptoms such as peripheral vision loss and sudden vision loss with flashes and floaters, respectively.

Age-related macular degeneration (ARMD) is a common cause of blindness in the UK, characterized by the degeneration of the central retina (macula) and the formation of drusen. It is more prevalent in females and is strongly associated with advancing age, smoking, family history, and conditions that increase the risk of ischaemic cardiovascular disease. ARMD can be classified into two forms: dry and wet. Dry ARMD is more common and is characterized by drusen, while wet ARMD is characterized by choroidal neovascularisation and carries a worse prognosis. Clinical features of ARMD include subacute onset of visual loss, difficulties in dark adaptation, and visual disturbances such as photopsia and glare.

To diagnose ARMD, slit-lamp microscopy and color fundus photography are used to identify any pigmentary, exudative, or haemorrhagic changes affecting the retina. Fluorescein angiography and indocyanine green angiography may also be used to visualize changes in the choroidal circulation. Treatment for dry ARMD involves a combination of zinc with anti-oxidant vitamins A, C, and E, which has been shown to reduce disease progression by around one third. For wet ARMD, anti-VEGF agents such as ranibizumab, bevacizumab, and pegaptanib are used to limit disease progression and stabilize or reverse visual loss. Laser photocoagulation may also be used to slow progression, but anti-VEGF therapies are usually preferred due to the risk of acute visual loss after treatment.

In summary, ARMD is a common cause of blindness in the UK that is strongly associated with advancing age, smoking, and family history. It can be classified into dry and wet forms, with wet ARMD carrying a worse prognosis. Diagnosis involves the use of various imaging techniques, and treatment options include a combination of zinc and anti-oxidant vitamins for dry ARMD and anti-VEGF agents or laser photocoagulation for wet ARMD.
