The recommended first-line treatment for menorrhagia is the intra-uterine system (IUS), which has a high success rate in stopping bleeding and only requires one insertion procedure. Additionally, it provides reliable contraception. Conversely, the copper coil may exacerbate menorrhagia symptoms. While medication such as the progesterone-only pill or combined oral contraceptive pill can be used, they are not the first choice. It would be an extreme measure to refer a woman of child-bearing age for a hysterectomy, especially when there are less invasive and reversible options available to treat menorrhagia, even if the patient expresses no desire for children.

Managing Heavy Menstrual Bleeding

Heavy menstrual bleeding, also known as menorrhagia, is a condition where a woman experiences excessive blood loss during her menstrual cycle. While it was previously defined as total blood loss of over 80 ml per cycle, the management of menorrhagia now depends on the woman’s perception of what is excessive. In the past, hysterectomy was a common treatment for heavy periods, but the approach has changed significantly since the 1990s.

To manage menorrhagia, a full blood count should be performed in all women. If symptoms suggest a structural or histological abnormality, a routine transvaginal ultrasound scan should be arranged. For women who do not require contraception, mefenamic acid or tranexamic acid can be used. If there is no improvement, other drugs can be tried while awaiting referral.

For women who require contraception, options include the intrauterine system (Mirena), combined oral contraceptive pill, and long-acting progestogens. Norethisterone can also be used as a short-term option to rapidly stop heavy menstrual bleeding. The flowchart below shows the management of menorrhagia.

When a condition has low genetic penetrance, it may not show many clinical signs or symptoms, and the patient may appear normal, despite having an abnormal genetic profile. This is because the severity of the phenotype is determined by the penetrance of the genotype. If the condition has high penetrance, the phenotype is more likely to be expressed, resulting in more signs and symptoms.

Autosomal Dominant Diseases: Characteristics and Complicating Factors

Autosomal dominant diseases are genetic disorders that are inherited from one parent who carries the abnormal gene. In these diseases, both homozygotes and heterozygotes manifest the disease, and both males and females can be affected. The disease is passed on to 50% of children, and it normally appears in every generation. The risk remains the same for each successive pregnancy.

However, there are complicating factors that can affect the expression of the disease. Non-penetrance is a phenomenon where an individual carries the abnormal gene but does not show any clinical signs or symptoms of the disease. For example, 40% of individuals with otosclerosis do not show any symptoms despite carrying the abnormal gene. Another complicating factor is spontaneous mutation, where a new mutation occurs in one of the gametes. This can result in the disease appearing in a child even if both parents do not carry the abnormal gene. For instance, 80% of individuals with achondroplasia have unaffected parents.

In summary, autosomal dominant diseases have distinct characteristics such as their inheritance pattern and the fact that affected individuals can pass on the disease. However, complicating factors such as non-penetrance and spontaneous mutation can affect the expression of the disease and make it more difficult to predict its occurrence.

The latest recommendations state that individuals should limit their alcohol consumption to no more than 14 units per week, regardless of gender. Additionally, it is suggested that individuals should spread out their drinking over a minimum of three days if they regularly consume 14 units per week.

Alcohol consumption guidelines were revised in 2016 by the Chief Medical Officer, based on recommendations from an expert group report. The most significant change was a reduction in the recommended maximum number of units of alcohol for men from 21 to 14, aligning with the guidelines for women. The government now advises that both men and women should not exceed 14 units of alcohol per week, and if they do, it is best to spread it evenly over three or more days. Pregnant women are advised not to drink alcohol at all, as it can cause long-term harm to the baby. One unit of alcohol is equivalent to 10 mL of pure ethanol, and the strength of a drink is determined by its alcohol by volume (ABV). Examples of one unit of alcohol include a 25ml single measure of spirits with an ABV of 40%, a third of a pint of beer with an ABV of 5-6%, and half a 175ml standard glass of red wine with an ABV of 12%. To calculate the number of units in a drink, multiply the number of millilitres by the ABV and divide by 1,000.

Respiratory Manifestations of Rheumatoid Arthritis

Rheumatoid arthritis (RA) is an inflammatory arthritis that can affect various parts of the body, including the respiratory tract. One common manifestation of RA in the respiratory system is pleural involvement, which can present as pleural effusion, pleural nodules, or pleurisy. Other respiratory complications associated with RA include pulmonary fibrosis and bronchiolitis obliterans.

It is important to note that other types of arthritis, such as ankylosing spondylitis, Behçet’s disease, gout, and psoriatic arthritis, do not typically present with respiratory complications like pleural effusion. Ankylosing spondylitis is associated with apical fibrosis, while Behçet’s disease is known for neurological complications. Gout is caused by purine metabolism abnormality and affects the joints and renal tract, while psoriatic arthritis is strongly associated with psoriasis and can lead to ocular and cardiovascular complications.

Overall, if a patient with RA presents with respiratory symptoms, it is important to consider the possibility of pleural involvement and other respiratory complications associated with the disease.

Patients who are taking warfarin or heparin should avoid taking selective serotonin reuptake inhibitors (SSRIs) due to their antiplatelet effect, which can increase the risk of bleeding. Therefore, citalopram is the appropriate choice. It is important to note that some tricyclic antidepressants and mirtazapine can also increase the INR, so caution is necessary when prescribing these medications. According to the Nice CKS guidelines on warfarin administration, trazodone may be the preferred antidepressant for these patients.

Selective serotonin reuptake inhibitors (SSRIs) are commonly used as the first-line treatment for depression. Citalopram and fluoxetine are the preferred SSRIs, while sertraline is recommended for patients who have had a myocardial infarction. However, caution should be exercised when prescribing SSRIs to children and adolescents. Gastrointestinal symptoms are the most common side-effect, and patients taking SSRIs are at an increased risk of gastrointestinal bleeding. Patients should also be aware of the possibility of increased anxiety and agitation after starting a SSRI. Fluoxetine and paroxetine have a higher propensity for drug interactions.

The Medicines and Healthcare products Regulatory Agency (MHRA) has issued a warning regarding the use of citalopram due to its association with dose-dependent QT interval prolongation. As a result, citalopram and escitalopram should not be used in patients with congenital long QT syndrome, known pre-existing QT interval prolongation, or in combination with other medicines that prolong the QT interval. The maximum daily dose of citalopram is now 40 mg for adults, 20 mg for patients older than 65 years, and 20 mg for those with hepatic impairment.

When initiating antidepressant therapy, patients should be reviewed by a doctor after 2 weeks. Patients under the age of 25 years or at an increased risk of suicide should be reviewed after 1 week. If a patient responds well to antidepressant therapy, they should continue treatment for at least 6 months after remission to reduce the risk of relapse. When stopping a SSRI, the dose should be gradually reduced over a 4 week period, except for fluoxetine. Paroxetine has a higher incidence of discontinuation symptoms, including mood changes, restlessness, difficulty sleeping, unsteadiness, sweating, gastrointestinal symptoms, and paraesthesia.

When considering the use of SSRIs during pregnancy, the benefits and risks should be weighed. Use during the first trimester may increase the risk of congenital heart defects, while use during the third trimester can result in persistent pulmonary hypertension of the newborn. Paroxetine has an increased risk of congenital malformations, particularly in the first trimester.

Assessing medications in elderly patients can be challenging, as they may be taking unnecessary or harmful drugs. The STOPP-START Criteria (Gallagher et al., 2008) provides guidance on medications that should be considered for discontinuation in the elderly. In this case, the patient has gout, which can be aggravated by bendroflumethiazide, an outdated thiazide diuretic that is no longer recommended by NICE. Additionally, her blood pressure is well below the target for her age, which is 150/90 mmHg in clinic. Ramipril is a more suitable antihypertensive medication to continue for now, but it may also be discontinued if her blood pressure remains low. The patient requires aspirin and atorvastatin for her ischemic heart disease, and allopurinol for her gout.

NICE Guidelines for Managing Hypertension

Hypertension, or high blood pressure, is a common condition that can lead to serious health problems if left untreated. The National Institute for Health and Care Excellence (NICE) has published updated guidelines for the management of hypertension in 2019. Some of the key changes include lowering the threshold for treating stage 1 hypertension in patients under 80 years old, allowing the use of angiotensin receptor blockers instead of ACE inhibitors, and recommending the use of a calcium channel blocker or thiazide-like diuretic in addition to an ACE inhibitor or angiotensin receptor blocker.

The guidelines also provide a flow chart for the diagnosis and management of hypertension. Lifestyle advice, such as reducing salt intake, caffeine intake, and alcohol consumption, as well as exercising more and losing weight, should not be forgotten and is frequently tested in exams. Treatment options depend on the patient’s age, ethnicity, and other factors, and may involve a combination of drugs.

NICE recommends treating stage 1 hypertension in patients under 80 years old if they have target organ damage, established cardiovascular disease, renal disease, diabetes, or a 10-year cardiovascular risk equivalent to 10% or greater. For patients with stage 2 hypertension, drug treatment should be offered regardless of age. The guidelines also provide step-by-step treatment options, including adding a third or fourth drug if necessary.

New drugs, such as direct renin inhibitors like Aliskiren, may have a role in patients who are intolerant of more established antihypertensive drugs. However, trials have only investigated the fall in blood pressure and no mortality data is available yet. Patients who fail to respond to step 4 measures should be referred to a specialist. The guidelines also provide blood pressure targets for different age groups.

Patients with symptoms of pulmonary embolism, such as chest pain and shortness of breath, are typically treated for 3 months if the PE is provoked. This is especially true for patients who have had recent surgery, as they are at a higher risk for a provoked PE. Clinical signs of a PE include tachycardia, hypoxia, and an elevated D-dimer. ECG changes may include sinus tachycardia, S1Q3T3, and T-wave inversion in the right-sided leads. Patients with right heart strain may also have raised troponin levels. The treatment of choice for a provoked PE is a low-molecular-weight heparin or a direct oral anticoagulant. Apixaban for 6 months is used for unprovoked PEs without risk factors, while apixaban for 12 months is not routinely prescribed. Dual antiplatelet therapy is used for coronary ischaemia, but a raised D-dimer, hypoxia, and ECG changes suggest a PE is more likely.

Management of Pulmonary Embolism: NICE Guidelines

Pulmonary embolism (PE) is a serious condition that requires prompt management. The National Institute for Health and Care Excellence (NICE) updated their guidelines on the management of venous thromboembolism (VTE) in 2020, with some key changes. One of the significant changes is the recommendation to use direct oral anticoagulants (DOACs) as the first-line treatment for most people with VTE, including those with active cancer. Another change is the increasing use of outpatient treatment for low-risk PE patients, determined by a validated risk stratification tool.

Anticoagulant therapy is the cornerstone of VTE management, and the guidelines recommend using apixaban or rivaroxaban as the first-line treatment following the diagnosis of a PE. If neither of these is suitable, LMWH followed by dabigatran or edoxaban or LMWH followed by a vitamin K antagonist (VKA) can be used. For patients with active cancer, DOACs are now recommended instead of LMWH. The length of anticoagulation is determined by whether the VTE was provoked or unprovoked, with treatment typically stopped after 3-6 months for provoked VTE and continued for up to 6 months for unprovoked VTE.

In cases of haemodynamic instability, thrombolysis is recommended as the first-line treatment for massive PE with circulatory failure. Patients who have repeat pulmonary embolisms, despite adequate anticoagulation, may be considered for inferior vena cava (IVC) filters. However, the evidence base for IVC filter use is weak.

Overall, the updated NICE guidelines provide clear recommendations for the management of PE, including the use of DOACs as first-line treatment and outpatient management for low-risk patients. The guidelines also emphasize the importance of individualized treatment based on risk stratification and balancing the risks of VTE recurrence and bleeding.

The patient’s symptoms suggest Brown-Séquard syndrome, which is caused by a hemisection of the spinal cord. This results in ipsilateral pyramidal weakness and loss of joint position/vibration sense, along with contralateral loss of pain/temperature sensation. The patient’s lesion is located in the left mid-thoracic cord. A lesion in the left lumbosacral plexus would only affect the left lower limb. A cervical cord lesion would affect the upper limbs. A central lesion would produce bilateral symmetrical defects, which is not the case here. A right mid-thoracic cord lesion would produce similar symptoms, but on the right side instead. Other spinal cord syndromes include complete cord transection, anterior cord syndrome, subacute combined degeneration of the cord, syringomyelia, and cauda equina syndrome. Each of these has a distinct set of symptoms and affected areas.

Differential Diagnosis of a Patient with Depressive Symptoms

Depression is a common mental health condition that can present with a variety of symptoms. In this vignette, the patient shows signs of anhedonia, change in appetite, early morning awakening, psychomotor retardation, decreased sexual drive, poor concentration, ideas of worthlessness or guilt, and thoughts of death and suicide. To diagnose and classify depression, various assessment tools are available, such as the PHQ-9, Hospital Anxiety and Depression (HAD) Scale, and Beck Depression Inventory.

Other possible diagnoses that need to be ruled out include acute alcohol withdrawal, acute psychosis, hypomania, and schizophrenia. Acute alcohol withdrawal typically manifests with psychomotor agitation, anxiety, tremor, insomnia, nausea, vomiting, hallucinations, seizures, and autonomic instability. Delirium tremens is a severe complication of alcohol withdrawal that can be life-threatening. Acute psychosis is characterized by delusions, hallucinations, or thought disorder. Hypomania is a milder form of mania that features elated mood, pressure of speech, increased energy, activity, appetite, sexual desire, and pain threshold, but does not cause significant impairment. Schizophrenia is a chronic and severe mental disorder that involves a range of cognitive, emotional, and behavioral symptoms, including hallucinations, delusions, disorganized speech, and social withdrawal.

Therefore, a thorough evaluation of the patient’s history, physical examination, and mental status is necessary to arrive at an accurate diagnosis and develop an appropriate treatment plan. Collaborating with a mental health specialist may also be beneficial in managing complex cases of depression or other mental health conditions.

The appropriate treatment for a patient with acute angle closure glaucoma (AACG) is to administer pilocarpine, timolol, and brimonidine eye drops. This condition is characterized by ocular pain, decreased visual acuity, worsened symptoms with mydriasis, and haloes around lights. AACG is more common in individuals with hypermetropia. The presence of a fixed mid-dilated pupil and inability to visualize the trabecular meshwork are consistent with AACG. Pilocarpine, timolol, and brimonidine are all used to reduce intra-ocular pressure (IOP) and protect the optic nerve.

Administering gentamicin eye drops is not appropriate for this patient as it is an antibiotic used to treat eye infections such as microbial keratitis. The patient does not have risk factors for an eye infection and the examination findings are more consistent with AACG.

Prescribing prednisolone eye drops is also not appropriate as it is a steroid used to manage inflammatory eye diseases such as anterior uveitis. While anterior uveitis may present with a painful red eye, the examination findings for this patient are more suggestive of angle closure.

Similarly, prescribing cyclopentolate eye drops is not appropriate as it is a mydriatic eye drop that may worsen the patient’s symptoms by reducing the angle. Mydriatic eye drops may be used in the management of anterior uveitis, but the examination findings for this patient are more consistent with AACG.

Glaucoma is a group of disorders that cause optic neuropathy due to increased intraocular pressure (IOP). However, not all patients with raised IOP have glaucoma, and vice versa. Acute angle-closure glaucoma (AACG) is a type of glaucoma where there is a rise in IOP due to impaired aqueous outflow. Factors that increase the risk of AACG include hypermetropia, pupillary dilatation, and lens growth associated with age. Symptoms of AACG include severe pain, decreased visual acuity, haloes around lights, and a hard, red-eye. Management of AACG is an emergency and requires urgent referral to an ophthalmologist. Emergency medical treatment is necessary to lower the IOP, followed by definitive surgical treatment once the acute attack has subsided.

There are no specific guidelines for the initial medical treatment of AACG, but a combination of eye drops may be used, including a direct parasympathomimetic, a beta-blocker, and an alpha-2 agonist. Intravenous acetazolamide may also be administered to reduce aqueous secretions. Definitive management of AACG involves laser peripheral iridotomy, which creates a small hole in the peripheral iris to allow aqueous humour to flow to the angle. It is important to seek medical attention immediately if symptoms of AACG are present to prevent permanent vision loss.
