Ankylosing spondylitis is characterized by an early reduction in lateral flexion of the lumbar spine. Patients with this condition often experience a decrease in lumbar lordosis and an increase in thoracic kyphosis.

Ankylosing spondylitis is a type of spondyloarthropathy that is associated with HLA-B27. It is more commonly seen in young males, with a sex ratio of 3:1, and typically presents with lower back pain and stiffness that develops gradually. The stiffness is usually worse in the morning and improves with exercise, while pain at night may improve upon getting up. Clinical examination may reveal reduced lateral and forward flexion, as well as reduced chest expansion. Other features associated with ankylosing spondylitis include apical fibrosis, anterior uveitis, aortic regurgitation, Achilles tendonitis, AV node block, amyloidosis, cauda equina syndrome, and peripheral arthritis (more common in females).

To calculate the breakthrough dose, we need to first convert oral codeine to oral morphine by dividing by 10. For example, 10mg of oral codeine is equivalent to 1mg of oral morphine.

If a person takes 30mg of oral codeine four times a day, this equals 12mg of oral morphine. If they also take 20mg of oral morphine four times a day, the total daily dose of morphine is 92mg (12mg + 80 mg).

To determine the breakthrough dose, we divide the total daily dose of morphine by 6. In this case, the breakthrough dose would be 15mg of morphine.

Palliative care prescribing for pain is guided by NICE and SIGN guidelines. NICE recommends starting treatment with regular oral modified-release or immediate-release morphine, with immediate-release morphine for breakthrough pain. Laxatives should be prescribed for all patients initiating strong opioids, and antiemetics should be offered if nausea persists. Drowsiness is usually transient, but if it persists, the dose should be adjusted. SIGN advises that the breakthrough dose of morphine is one-sixth the daily dose, and all patients receiving opioids should be prescribed a laxative. Opioids should be used with caution in patients with chronic kidney disease, and oxycodone is preferred to morphine in patients with mild-moderate renal impairment. Metastatic bone pain may respond to strong opioids, bisphosphonates, or radiotherapy, and all patients should be considered for referral to a clinical oncologist for further treatment. When increasing the dose of opioids, the next dose should be increased by 30-50%. Conversion factors between opioids are also provided. Opioid side-effects are usually transient, such as nausea and drowsiness, but constipation can persist. In addition to strong opioids, bisphosphonates, and radiotherapy, denosumab may be used to treat metastatic bone pain.

Overall, the guidelines recommend starting with regular oral morphine and adjusting the dose as needed. Laxatives should be prescribed to prevent constipation, and antiemetics may be needed for nausea. Opioids should be used with caution in patients with chronic kidney disease, and oxycodone is preferred in patients with mild-moderate renal impairment. Metastatic bone pain may respond to strong opioids, bisphosphonates, or radiotherapy, and referral to a clinical oncologist should be considered. Conversion factors between opioids are provided, and the next dose should be increased by 30-50% when adjusting the dose. Opioid side-effects are usually transient, but constipation can persist. Denosumab may also be used to treat metastatic bone pain.

If a child under the age of 5 has asthma that is not being controlled by a short-acting beta agonist (SABA) and a low dose of inhaled corticosteroids (ICS), then a leukotriene receptor antagonist should be added to their asthma management plan.

Managing Asthma in Children: NICE Guidelines

Asthma management in children has been updated by NICE in 2017, following the 2016 BTS guidelines. The new guidelines for children aged 5-16 are similar to those for adults, with a stepwise approach for treatment. For newly-diagnosed asthma, short-acting beta agonist (SABA) is recommended. If symptoms persist, a combination of SABA and paediatric low-dose inhaled corticosteroid (ICS) is used. Leukotriene receptor antagonist (LTRA) is added if symptoms still persist, followed by long-acting beta agonist (LABA) if necessary. Maintenance and reliever therapy (MART) is used as a combination of ICS and LABA for daily maintenance therapy and symptom relief. For children under 5 years old, clinical judgement plays a greater role in diagnosis. The stepwise approach is similar to that for older children, with an 8-week trial of paediatric moderate-dose ICS before adding LTRA. If symptoms persist, referral to a paediatric asthma specialist is recommended.

It should be noted that NICE does not recommend changing treatment for well-controlled asthma patients simply to adhere to the latest guidelines. The definitions of low, moderate, and high-dose ICS have also changed, with different definitions for adults and children. For children, <= 200 micrograms budesonide or equivalent is considered a paediatric low dose, 200-400 micrograms is a moderate dose, and > 400 micrograms is a high dose. Overall, the new NICE guidelines provide a clear and concise approach to managing asthma in children.

A suitable medication would have been a DDP-4 inhibitor, glitazone, or sulfonylurea. The use of GLP-1 receptor agonists is not appropriate, as it is only recommended when triple therapy with metformin and two other oral drugs has failed.

NICE updated its guidance on the management of type 2 diabetes mellitus (T2DM) in 2022, reflecting advances in drug therapy and improved evidence regarding newer therapies such as SGLT-2 inhibitors. The first-line drug of choice remains metformin, which should be titrated up slowly to minimize gastrointestinal upset. HbA1c targets should be agreed upon with patients and checked every 3-6 months until stable, with consideration for relaxing targets on a case-by-case basis. Dietary advice includes encouraging high fiber, low glycemic index sources of carbohydrates and controlling intake of foods containing saturated fats and trans fatty acids. Blood pressure targets are the same as for patients without type 2 diabetes, and antiplatelets should not be offered unless a patient has existing cardiovascular disease. Only patients with a 10-year cardiovascular risk > 10% should be offered a statin, with atorvastatin 20mg as the first-line choice.

In cases where neutropenic sepsis is suspected, immediate administration of IV antibiotics, such as piperacillin/tazobactam, is crucial, even if the diagnosis has not been confirmed yet. This is because patients with neutropenic sepsis may not exhibit obvious signs or symptoms of infection due to their weakened immune response, and delaying treatment can be potentially fatal. Therefore, waiting for the results of a full blood count or blood cultures is not recommended before starting treatment. While blood cultures should be taken as soon as possible, broad-spectrum antibiotics should be given first to provide urgent cover. Nitrofurantoin may be used for a urinary tract infection, but it is not appropriate for immediate treatment of neutropenic sepsis.

Neutropenic Sepsis: A Common Complication of Cancer Therapy

Neutropenic sepsis is a frequent complication of cancer therapy, particularly chemotherapy. It typically occurs within 7-14 days after chemotherapy and is characterized by a neutrophil count of less than 0.5 * 109 in patients undergoing anticancer treatment who exhibit a temperature higher than 38ºC or other signs or symptoms consistent with clinically significant sepsis.

To prevent neutropenic sepsis, patients who are likely to have a neutrophil count of less than 0.5 * 109 as a result of their treatment should be offered a fluoroquinolone. In the event of neutropenic sepsis, antibiotics must be initiated immediately, without waiting for the white blood cell count.

According to NICE guidelines, empirical antibiotic therapy should begin with piperacillin with tazobactam (Tazocin) immediately. While some units may add vancomycin if the patient has central venous access, NICE does not support this approach. After initial treatment, patients are typically assessed by a specialist and risk-stratified to determine if they may be able to receive outpatient treatment.

If patients remain febrile and unwell after 48 hours, an alternative antibiotic such as meropenem may be prescribed, with or without vancomycin. If patients do not respond after 4-6 days, the Christie guidelines suggest ordering investigations for fungal infections (e.g. HRCT) rather than blindly initiating antifungal therapy. In selected patients, G-CSF may be beneficial.

Approaches to Managing Dyspepsia in Patients with Gastro-Oesophageal Reflux Disease

Patients with chronic gastro-oesophageal reflux disease (GORD) are at risk of developing Barrett’s oesophagus and oesophageal cancer. Therefore, patients aged 50 years or older with a history of chronic GORD should undergo at least one upper gastrointestinal (GI) endoscopy to screen for these conditions. In younger patients, long-term low-dose proton pump inhibitor (PPI) therapy may be considered, with dose adjustment if necessary. However, ongoing dyspepsia in a patient over 50 years old warrants further investigation to exclude serious pathology. Intermittent high-dose PPI therapy is currently only used in hospital for specific indications. Counselling with false reassurance should be avoided in patients with concerning symptoms.

Wolff-Parkinson-White (WPW) syndrome is a condition where there is an extra electrical pathway in the heart, making the patient more susceptible to developing supraventricular tachycardia (SVT). The presence of delta waves, which are a slurred upstroke in the QRS complex, and a shortened PR interval are characteristic of WPW syndrome. Atrial fibrillation (AF), on the other hand, is an irregularly irregular pulse that is diagnosed by the absence of P waves and irregular QRS complexes on an ECG. Delta waves are not typically seen in AF unless the patient also has WPW syndrome. Sinus arrhythmia, which is an irregular rhythm, does not show delta waves on an ECG. Acute myocardial infarction (MI) is not associated with delta waves, but rather with ST elevation or depression and T wave inversion. Supraventricular tachycardia (SVT) is a regular narrow complex tachycardia that may or may not have delta waves, depending on whether the patient has underlying WPW syndrome.

To avoid reduced absorption of levothyroxine, iron/calcium carbonate tablets should be administered four hours apart.

Managing Hypothyroidism: Dosage, Monitoring, and Side-Effects

Hypothyroidism is a condition where the thyroid gland does not produce enough thyroid hormone. The main treatment for hypothyroidism is levothyroxine, a synthetic form of thyroid hormone. When managing hypothyroidism, it is important to consider the patient’s age, cardiac history, and initial starting dose. Elderly patients and those with ischaemic heart disease should start with a lower dose of 25mcg od, while other patients can start with 50-100mcg od. After a change in dosage, thyroid function tests should be checked after 8-12 weeks to ensure the therapeutic goal of normalising the thyroid stimulating hormone (TSH) level is achieved. The target TSH range is 0.5-2.5 mU/l.

Women with hypothyroidism who become pregnant should have their dose increased by at least 25-50 micrograms levothyroxine due to the increased demands of pregnancy. The TSH should be monitored carefully, aiming for a low-normal value. It is important to note that there is no evidence to support combination therapy with levothyroxine and liothyronine.

While levothyroxine is generally well-tolerated, there are some potential side-effects to be aware of. Over-treatment can lead to hyperthyroidism, while long-term use can reduce bone mineral density. In patients with cardiac disease, levothyroxine can worsen angina and lead to atrial fibrillation. It is also important to be aware of drug interactions, particularly with iron and calcium carbonate, which can reduce the absorption of levothyroxine. These medications should be given at least 4 hours apart.

In summary, managing hypothyroidism involves careful consideration of dosage, monitoring of TSH levels, and awareness of potential side-effects and drug interactions. With appropriate management, patients with hypothyroidism can achieve normal thyroid function and improve their overall health.

Differential Diagnosis for Joint and Muscle Pain: A Case Study

A 75-year-old male patient presents with pain and stiffness in the joints and muscles around the pelvic and shoulder girdles, lasting for longer than 45 minutes in the morning. He also reports constitutional symptoms of malaise, fatigue, anorexia, and sometimes depression. Based on this presentation, the following differential diagnoses can be considered:

Polymyalgia Rheumatica (PMR)
PMR is a rare condition that is most often diagnosed in those over 70 years old and is more common in women than men. Patients with PMR present with pain and stiffness in the joints and muscles around the pelvic and shoulder girdles, along with constitutional symptoms. Diagnosis is made based on the history, and blood tests often show a raised ESR and CRP. Treatment is with prednisolone, and rapid response to corticosteroid treatment is a very good indicator of a diagnosis of PMR.

Osteoarthritis
Although osteoarthritis may present with painful hip joints, it is less common in the shoulder. Furthermore, constitutional symptoms, such as malaise and anorexia, are not seen in osteoarthritis. Examination findings in osteoarthritis usually reveal limited range of movement, crepitus, and possible joint instability, and there is unlikely to be any associated muscle tenderness. ESR, a marker of inflammation, is not seen in osteoarthritis.

Systemic Lupus Erythematosus (SLE)
SLE is an autoimmune condition that is most common in women of childbearing age and those of Afro-Caribbean origin. While arthritis is one of the symptoms of SLE and there may be a raised ESR, alongside constitutional symptoms, the presentation in this patient, especially given his age and sex, suggests an alternative diagnosis to SLE initially. SLE may present with other symptoms as well, such as the characteristic butterfly rash, which is present in 30–60% of patients.

Rheumatoid Arthritis (RA)
The onset of RA is generally in the middle-aged, and women are affected 2.5 times more than men. Although the ESR may be raised and the patient may feel generally unwell, the history given here is not typical of RA. The joints most typically affected by RA are the small joints of the hands and feet and the cervical spine.

Gout
Gout presents as a mono

In cases of ocular trauma, it is important to assess for orbital compartment syndrome as it may require urgent decompression before any imaging is done.

A man presents with symptoms of orbital compartment syndrome, including blood in the front part of the eye, bulging of the eye, a stiff eyelid, and a pupil defect. This is a medical emergency that requires immediate attention as it can lead to permanent vision loss. The condition is caused by an increase in volume within the orbit, which can be due to bleeding or swelling of the eye. It can be caused by surgical or external trauma, such as a sports injury. In this case, the correct course of action is to perform an immediate canthotomy to relieve the pressure.

B-scan ultrasonography is not the correct answer. This imaging technique is useful for examining the back part of the eye and is used to diagnose conditions such as retinal detachment or vitreous hemorrhage. It is not helpful in diagnosing orbital compartment syndrome.

Immediate IV acetazolamide is also not the correct answer. While this medication can be used to reduce intraocular pressure in acute closed-angle glaucoma, it is not the primary treatment for orbital compartment syndrome.

Non-contrast head CT is not the correct answer either. While this imaging test can help confirm the diagnosis and determine the cause of the condition, it should not be done before immediate surgical decompression is performed due to the severity of the condition.

Ocular Trauma and Hyphema

Ocular trauma can lead to hyphema, which is the presence of blood in the anterior chamber of the eye. This condition requires immediate referral to an ophthalmic specialist for assessment and management. The main concern is the risk of raised intraocular pressure due to the blockage of the angle and trabecular meshwork with erythrocytes. Patients with high-risk cases are often admitted and require strict bed rest to prevent the redispersement of blood. Even isolated hyphema requires daily ophthalmic review and pressure checks initially as an outpatient.

In addition to hyphema, an assessment should also be made for orbital compartment syndrome, which can occur secondary to retrobulbar hemorrhage. This is a true ophthalmic emergency and requires urgent management. Symptoms of orbital compartment syndrome include eye pain and swelling, proptosis, ‘rock hard’ eyelids, and a relevant afferent pupillary defect.

To manage orbital compartment syndrome, urgent lateral canthotomy is necessary to decompress the orbit. This should be done before diagnostic imaging to prevent further damage. Proper management and prompt referral to an ophthalmic specialist can help prevent vision loss and other complications associated with ocular trauma and hyphema.

Understanding the Risk Factors for Gout

Gout is a painful condition caused by hyperuricaemia, which can be influenced by various risk factors. While the cause of hyperuricaemia is multifactorial, certain factors have been identified as predisposing individuals to gout. These include high BMI, male gender, cardiovascular disease, renal disease, diabetes, and the use of certain drugs such as diuretics. Additionally, alcohol excess, particularly from spirits and beer, has been shown to increase the risk of gout. However, eczema and smoking are not recognized as risk factors for gout. Interestingly, gout is more common in men and rare in premenopausal women, and being overweight, rather than underweight, has been proposed as a risk factor for gout. Understanding these risk factors can help individuals take steps to prevent or manage gout.

Most Common Cancers in Women in the UK

Breast cancer is the most frequently diagnosed cancer in women in the UK, with approximately 54,800 cases in 2014. Lung cancer follows as the second most common cancer in women, with around 21,600 cases diagnosed in the same year. Bowel cancer ranks third, with approximately 18,400 cases diagnosed in 2014. Uterine cancer is the fourth most common cancer in women, with around 9,300 cases diagnosed. Leukaemia is the eleventh most common cancer in women, with approximately 3,800 cases diagnosed in 2014. These statistics are according to Cancer Research UK.

Treatment Options for Nephrogenic Diabetes Insipidus

Nephrogenic diabetes insipidus is a condition where the kidneys are unable to respond to ADH, resulting in excessive urination and thirst. Thiazide diuretics are paradoxically used to treat this condition by blocking the NaCl transporter in the distal tubule, leading to increased uptake of sodium and water in the proximal collecting duct. This results in less water loss through urination and improved symptoms. Desmopressin is not effective in treating nephrogenic diabetes insipidus as it works by increasing ADH levels. Loop diuretics like bumetanide are not used to treat this condition. Insulin has no use in diabetes insipidus. Terlipressin is only effective in cranial diabetes insipidus.

Herpes Zoster Ophthalmicus: Symptoms, Treatment, and Complications

Herpes zoster, commonly known as shingles, is a reactivation of the varicella-zoster virus that causes chickenpox. Herpes zoster ophthalmicus (HZO) occurs when the virus affects the trigeminal nerve, resulting in eye involvement in about 50% of cases. Symptoms include patchy erythema and grouped herpetiform vesicles, which may extend to the tip of the nose. Other ophthalmic manifestations include conjunctivitis, scleritis, keratitis, and optic neuritis. Urgent referral to ophthalmology is necessary in the presence of eye involvement, as it poses a risk to vision. Treatment involves oral aciclovir and topical aciclovir for severe eye infection. There is no recommendation for the use of carbamazepine in the management of post-herpetic neuralgia. Topical steroids are not indicated for herpes zoster infection. Complications of HZO include post-herpetic neuralgia and scarring. Aggressive treatment and follow-up monitoring are required for HZO due to the possibility of eye involvement.

The recommended first-line antibiotic for patients with low severity community-acquired pneumonia (CAP) is oral amoxicillin. Therefore, it is appropriate to discharge this patient with oral amoxicillin as they present with symptoms of CAP, including a new cough, temperature, purulent sputum, and focal chest signs. While a chest x-ray could confirm the diagnosis, it is not usually necessary for suspected CAP managed in primary care. The patient’s CRB-65 score is 0, indicating that they can be managed in the community. Hospitalization may be required for patients with higher scores or clinical factors that increase the risk of complications, but this is not the case for this patient. Discharge with oral clarithromycin or doxycycline is not appropriate as there is no indication that amoxicillin is unsuitable as the first-line antibiotic.

Pneumonia is a serious respiratory infection that requires prompt assessment and management. In the primary care setting, the CRB65 criteria are used to stratify patients based on their risk of mortality. Patients with a score of 0 are considered low risk and may be treated at home, while those with a score of 3 or 4 are high risk and require urgent admission to hospital. The use of a point-of-care CRP test can help guide antibiotic therapy. In the secondary care setting, the CURB65 criteria are used, which includes an additional criterion of urea > 7 mmol/L. Chest x-rays and blood and sputum cultures are recommended for intermediate or high-risk patients. Treatment for low-severity community acquired pneumonia typically involves a 5-day course of amoxicillin, while moderate and high-severity cases may require dual antibiotic therapy for 7-10 days. Discharge criteria and advice post-discharge are also provided, including information on expected symptom resolution timeframes and the need for a repeat chest x-ray at 6 weeks.

In cases of iron-deficiency anemia, it is common for both the total iron-binding capacity (TIBC) and transferrin levels to be elevated. However, it should be noted that the transferrin saturation level is typically decreased.

Iron deficiency anaemia is caused by a lack of iron, which is needed to make haemoglobin in red blood cells. It is the most common type of anaemia worldwide, with preschool-age children having the highest prevalence. Causes include excessive blood loss, inadequate dietary intake, poor intestinal absorption, and increased iron requirements. Symptoms include fatigue, shortness of breath, palpitations, and nail changes. Diagnosis is made through a full blood count and serum ferritin test. Treatment involves identifying and managing the underlying cause, as well as taking oral iron supplements and consuming an iron-rich diet.

Performing an HIV test is crucial in patients with AIDS, as it is the primary diagnostic tool for identifying the underlying cause. While options 1, 2, and 3 may be necessary as baseline investigations in most patients, they are not sufficient for diagnosing the specific condition in this case.

Causes of Chorioretinitis

Chorioretinitis is a medical condition that affects the retina and choroid, which are the layers of tissue at the back of the eye. There are several causes of chorioretinitis, including syphilis, cytomegalovirus, toxoplasmosis, sarcoidosis, and tuberculosis.

Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum. It can cause chorioretinitis as part of its secondary stage. Cytomegalovirus is a common virus that can cause chorioretinitis in people with weakened immune systems, such as those with HIV/AIDS. Toxoplasmosis is a parasitic infection that can be contracted from contaminated food or water, and it can cause chorioretinitis in some cases.

Sarcoidosis is a condition that causes inflammation in various parts of the body, including the eyes. It can lead to chorioretinitis in some cases. Tuberculosis is a bacterial infection that can affect the lungs, but it can also spread to other parts of the body, including the eyes. It can cause chorioretinitis as a rare complication.

Migraine sufferers often experience visual symptoms before the onset of a headache, such as wavy or shimmering lines known as a scintillating scotoma. It is important to obtain a thorough medical history as the patient may not mention a history of headaches. A normal eye exam is crucial for proper diagnosis. The other conditions listed have associated exam findings, such as cells in the anterior chamber for uveitis, a pale disc and relative afferent pupillary defect for optic neuritis, and a Weiss ring appearance with occasional hemorrhage for posterior vitreous detachment.

Diagnostic Criteria for Migraine

Migraine is a neurological disorder that affects millions of people worldwide. The International Headache Society has established diagnostic criteria for migraine without aura, which includes at least five attacks lasting between 4-72 hours and having at least two of the following characteristics: unilateral location, pulsating quality, moderate or severe pain intensity, and aggravation by routine physical activity. During the headache, there must be at least one of the following: nausea and/or vomiting, photophobia, and phonophobia. The headache cannot be attributed to another disorder.

Migraine with aura, which is seen in around 25% of migraine patients, tends to be easier to diagnose with a typical aura being progressive in nature and may occur hours prior to the headache. Typical aura include a transient hemianopic disturbance or a spreading scintillating scotoma (‘jagged crescent’). Sensory symptoms may also occur. NICE criteria suggest that migraines may be unilateral or bilateral and give more detail about typical auras, which may occur with or without headache and are fully reversible, develop over at least 5 minutes, and last 5-60 minutes. Atypical aura symptoms such as motor weakness, double vision, visual symptoms affecting only one eye, poor balance, and decreased level of consciousness may prompt further investigation or referral.

In summary, the diagnostic criteria for migraine without aura include specific characteristics of the headache and associated symptoms, while migraine with aura is characterized by typical aura symptoms that may occur prior to the headache. It is important to accurately diagnose migraine to provide appropriate treatment and management for those who suffer from this debilitating condition.

Understanding Nasal Polyps

Nasal polyps are a relatively uncommon condition affecting around 1% of adults in the UK. They are more commonly seen in men and are not typically found in children or the elderly. There are several associations with nasal polyps, including asthma (particularly late-onset asthma), aspirin sensitivity, infective sinusitis, cystic fibrosis, Kartagener’s syndrome, and Churg-Strauss syndrome. When asthma, aspirin sensitivity, and nasal polyposis occur together, it is known as Samter’s triad.

The symptoms of nasal polyps include nasal obstruction, rhinorrhoea, sneezing, and a poor sense of taste and smell. It is important to note that any unusual symptoms, such as unilateral symptoms or bleeding, require further investigation. If nasal polyps are suspected, patients should be referred to an ear, nose, and throat (ENT) specialist for a full examination.

The management of nasal polyps typically involves the use of topical corticosteroids, which can shrink polyp size in around 80% of patients. Overall, understanding nasal polyps and their associations can help with early detection and appropriate management.

St John’s Wort: A Natural Remedy for Depression with Limitations

St John’s wort is a herbal supplement that has been studied for its potential to treat depression. While some studies have shown it to be as effective as standard antidepressants and superior to placebo, its place in the treatment of depression is still uncertain due to limitations in the available evidence base. St John’s wort works by inhibiting the reuptake of certain neurotransmitters, but it can also upregulate liver enzymes and cause liver damage with high-level, long-term use. Despite its potential benefits, it should be avoided in women on contraceptive pills and can interact with other medications such as digoxin and warfarin. While it is widely prescribed in the UK, it is not available on prescription and should be used with caution.

It is probable that the patient is experiencing conversion disorder, which is often triggered by stress and involves the loss of motor or sensory function. The potential grand final rugby game may have been the stressor in this case.

Somatisation disorder is unlikely as it requires the presence of multiple physical symptoms for at least two years, whereas this patient has only one acute onset symptom. Dissociative disorder is also improbable as there are no evident psychiatric symptoms such as amnesia, stupor, or fugue. The patient remembers clearly that he has a football game and has not sustained any recent injuries.

However, factitious disorder cannot be ruled out entirely. It is possible that the patient is feigning the symptom to avoid playing the game, but further investigation is necessary. The patient claims to be eager to return to playing, which does not support the notion of factitious disorder.

Psychiatric Terms for Unexplained Symptoms

There are various psychiatric terms used to describe patients who exhibit symptoms for which no organic cause can be found. One such disorder is somatisation disorder, which involves the presence of multiple physical symptoms for at least two years, and the patient’s refusal to accept reassurance or negative test results. Another disorder is illness anxiety disorder, which is characterized by a persistent belief in the presence of an underlying serious disease, such as cancer, despite negative test results.

Conversion disorder is another condition that involves the loss of motor or sensory function, and the patient does not consciously feign the symptoms or seek material gain. Patients with this disorder may be indifferent to their apparent disorder, a phenomenon known as la belle indifference. Dissociative disorder, on the other hand, involves the process of ‘separating off’ certain memories from normal consciousness, and may manifest as amnesia, fugue, or stupor. Dissociative identity disorder (DID) is the most severe form of dissociative disorder and was previously known as multiple personality disorder.

Factitious disorder, also known as Munchausen’s syndrome, involves the intentional production of physical or psychological symptoms. Finally, malingering is the fraudulent simulation or exaggeration of symptoms with the intention of financial or other gain. Understanding these psychiatric terms can help healthcare professionals better diagnose and treat patients with unexplained symptoms.

Edward’s syndrome is characterized by micrognathia, low-set ears, rocker bottom feet, and overlapping of fingers. The baby affected by this syndrome will have experienced slow growth in the womb and will have a low birthweight. Unfortunately, around half of those who survive to birth will pass away within two weeks, and only one in every five will live for at least three months. The survival rate beyond one year is only one in every 12 babies born with Edwards’ syndrome. This information is according to NHS Choices.

Childhood syndromes are a group of medical conditions that affect children and are characterized by a set of common features. Patau syndrome, also known as trisomy 13, is a syndrome that is characterized by microcephaly, small eyes, cleft lip/palate, polydactyly, and scalp lesions. Edward’s syndrome, also known as trisomy 18, is characterized by micrognathia, low-set ears, rocker bottom feet, and overlapping of fingers. Fragile X syndrome is characterized by learning difficulties, macrocephaly, long face, large ears, and macro-orchidism. Noonan syndrome is characterized by a webbed neck, pectus excavatum, short stature, and pulmonary stenosis. Pierre-Robin syndrome is characterized by micrognathia, posterior displacement of the tongue, and cleft palate. Prader-Willi syndrome is characterized by hypotonia, hypogonadism, and obesity. William’s syndrome is characterized by short stature, learning difficulties, friendly, extrovert personality, and transient neonatal hypercalcaemia. Cri du chat syndrome, also known as chromosome 5p deletion syndrome, is characterized by a characteristic cry, feeding difficulties and poor weight gain, learning difficulties, microcephaly and micrognathism, and hypertelorism. It is important to note that Treacher-Collins syndrome is similar to Pierre-Robin syndrome, but it is autosomal dominant and usually has a family history of similar problems.

The Afro-Caribbean population is more prone to developing prostate cancer.

Prostate cancer is currently the most prevalent cancer among adult males in the UK, and the second most common cause of cancer-related deaths in men, following lung cancer. The risk factors for prostate cancer include increasing age, obesity, Afro-Caribbean ethnicity, and a family history of the disease, which accounts for 5-10% of cases. Localized prostate cancer is often asymptomatic, as the cancer tends to develop in the outer part of the prostate gland, causing no obstructive symptoms in the early stages. However, some possible features of prostate cancer include bladder outlet obstruction, haematuria or haematospermia, and pain in the back, perineal or testicular area. A digital rectal examination may reveal asymmetrical, hard, nodular enlargement with loss of median sulcus. In addition, an isotope bone scan can be used to detect metastatic prostate cancer, which appears as multiple, irregular, randomly distributed foci of high-grade activity involving the spine, ribs, sternum, pelvic and femoral bones.

Spasticity in multiple sclerosis is caused by demyelination along the nerves that control movement, resulting in stiffness that can sometimes be helpful but can also become painful. Physiotherapy exercises are the simplest and most effective treatment, but first-line medications such as baclofen and gabapentin are also recommended. Gabapentin is an anticonvulsant that can be effective against muscle spasms, while diazepam is a muscle relaxant that may be more useful at night due to side effects at higher doses. Botulinum toxin and dantrolene sodium can be considered if conventional treatments prove ineffective, but are not used as first-line for spasticity. The NICE multiple sclerosis guideline recommends gabapentin as one of the first drugs to try in the treatment of spasms and spasticity.

Multiple sclerosis is a condition that cannot be cured, but its treatment aims to reduce the frequency and duration of relapses. In the case of an acute relapse, high-dose steroids may be administered for five days to shorten its length. However, it is important to note that steroids do not affect the degree of recovery. Disease-modifying drugs are used to reduce the risk of relapse in patients with MS. These drugs are typically indicated for patients with relapsing-remitting disease or secondary progressive disease who have had two relapses in the past two years and are able to walk a certain distance unaided. Natalizumab, ocrelizumab, fingolimod, beta-interferon, and glatiramer acetate are some of the drugs used to reduce the risk of relapse in MS.

Fatigue is a common problem in MS patients, and amantadine is recommended by NICE after excluding other potential causes such as anaemia, thyroid problems, or depression. Mindfulness training and CBT are other options for managing fatigue. Spasticity is another issue that can be addressed with first-line drugs such as baclofen and gabapentin, as well as physiotherapy. Cannabis and botox are currently being evaluated for their effectiveness in managing spasticity. Bladder dysfunction is also a common problem in MS patients, and anticholinergics may worsen symptoms in some patients. Ultrasound is recommended to assess bladder emptying, and intermittent self-catheterisation may be necessary if there is significant residual volume. Gabapentin is the first-line treatment for oscillopsia, which is a condition where visual fields appear to oscillate.

To manage a postpartum haemorrhage, an ABCDE approach should be taken, with initial steps including compressing the uterus and catheterising the patient. This is known as ‘mechanical management’ and is appropriate for a primary postpartum haemorrhage (PPH) where uterine atony is the most common cause. IV warmed crystalloid should also be given. Medical management options such as IV oxytocin or IM/IV carboprost should only be considered if mechanical methods fail. It is important to note that IV carboprost should not be administered as it can lead to serious side effects.

Understanding Postpartum Haemorrhage

Postpartum haemorrhage (PPH) is a condition where a woman experiences blood loss of more than 500 ml after giving birth vaginally. It can be classified as primary or secondary. Primary PPH occurs within 24 hours after delivery and is caused by the 4 Ts: tone, trauma, tissue, and thrombin. The most common cause is uterine atony. Risk factors for primary PPH include previous PPH, prolonged labour, pre-eclampsia, increased maternal age, emergency Caesarean section, and placenta praevia.

In managing PPH, it is important to involve senior staff immediately and follow the ABC approach. This includes two peripheral cannulae, lying the woman flat, blood tests, and commencing a warmed crystalloid infusion. Mechanical interventions such as rubbing up the fundus and catheterisation are also done. Medical interventions include IV oxytocin, ergometrine, carboprost, and misoprostol. Surgical options such as intrauterine balloon tamponade, B-Lynch suture, ligation of uterine arteries, and hysterectomy may be considered if medical options fail to control the bleeding.

Secondary PPH occurs between 24 hours to 6 weeks after delivery and is typically due to retained placental tissue or endometritis. It is important to understand the causes and risk factors of PPH to prevent and manage this life-threatening emergency effectively.

The use of carvedilol and bisoprolol has been proven to decrease mortality in stable heart failure patients, while there is no evidence to support the use of other beta-blockers.

Drug Management for Chronic Heart Failure: NICE Guidelines

Chronic heart failure is a serious condition that requires proper management to improve patient outcomes. In 2018, the National Institute for Health and Care Excellence (NICE) updated their guidelines on drug management for chronic heart failure. The guidelines recommend first-line therapy with both an ACE-inhibitor and a beta-blocker, with clinical judgement used to determine which one to start first. Second-line therapy involves the use of aldosterone antagonists, which should be monitored for hyperkalaemia. SGLT-2 inhibitors are also increasingly being used to manage heart failure with a reduced ejection fraction. Third-line therapy should be initiated by a specialist and may include ivabradine, sacubitril-valsartan, hydralazine in combination with nitrate, digoxin, or cardiac resynchronisation therapy. Other treatments such as annual influenza and one-off pneumococcal vaccines are also recommended.

Overall, the NICE guidelines provide a comprehensive approach to drug management for chronic heart failure. It is important to note that loop diuretics have not been shown to reduce mortality in the long-term, and that ACE-inhibitors and beta-blockers have no effect on mortality in heart failure with preserved ejection fraction. Healthcare professionals should carefully consider the patient’s individual needs and circumstances when determining the appropriate drug therapy for chronic heart failure.

If a lung abscess is not responding to intravenous antibiotics, percutaneous drainage should be considered as an option.

Correct: Arrange CT-guided percutaneous drainage. This is because the patient’s symptoms, such as swinging fevers, night sweats, pleuritic chest pain, dyspnoea, and cough, are consistent with a lung abscess. The chest x-ray also supports this diagnosis by showing a fluid-filled space within an area of consolidation. If IV antibiotics are not effective, percutaneous drainage can be guided by a CT scan or ultrasound. IV antibiotics may not be able to penetrate the abscess wall, which is why some patients do not respond to this treatment.

Incorrect: Arrange bronchoscopy. This is not commonly used for lung abscesses and is only indicated if an underlying tumour or foreign body is suspected. It is performed for diagnosis only, not drainage.

Incorrect: Arrange sputum cytology. Sputum cultures have already been collected, and a diagnosis of lung abscess has been established. This option could be considered later if the patient still does not respond to treatment to rule out an underlying malignancy.

Incorrect: Prescribe broad-spectrum IV antibiotics. This option is unlikely to be effective since the patient has already received IV antibiotics without success. The next step would be to manually drain the abscess.

Understanding Lung Abscess

A lung abscess is a localized infection that occurs within the lung tissue. It is commonly caused by aspiration pneumonia, which can be triggered by poor dental hygiene, reduced consciousness, or previous stroke. Other potential causes include haematogenous spread, direct extension, and bronchial obstruction. The infection is typically polymicrobial, with Staphylococcus aureus, Klebsiella pneumonia, and Pseudomonas aeruginosa being the most common monomicrobial causes.

The symptoms of lung abscess are similar to pneumonia, but they tend to develop more slowly over several weeks. Patients may experience fever, productive cough, foul-smelling sputum, chest pain, and dyspnea. Some may also have systemic features such as night sweats and weight loss, while a minority may experience haemoptysis. Physical examination may reveal dull percussion and bronchial breathing, as well as clubbing in some cases.

To diagnose lung abscess, a chest x-ray is usually performed, which shows a fluid-filled space within an area of consolidation. Sputum and blood cultures should also be obtained to identify the causative organism. Treatment typically involves intravenous antibiotics, but if the infection does not resolve, percutaneous drainage or surgical resection may be required in rare cases.

Oestrogen therapy must be continued for at least 5-10 years to maintain its benefits, including a decreased risk of fragility fractures. Starting oestrogen therapy immediately can prevent osteoporotic fractures in old age. Bisphosphonates are the first-line treatment for bone-sparing. HRT should not be prescribed solely for preventing osteoporosis, but a combination of oestrogen and progesterone should be used in women with a uterus. Patients who have a salpingo-oophorectomy should be monitored for hormone-related conditions. SSRIs, SNRIs, and clonidine should not be the first-line treatment for vasomotor symptoms alone. Vaginal oestrogen can be offered to women with urogenital atrophy, even if they are on systemic HRT.

The use of diclofenac is now prohibited for individuals with any type of cardiovascular ailment.

MHRA Guidance on Diclofenac and Cardiovascular Safety

The MHRA has updated its guidance on diclofenac, a nonsteroidal anti-inflammatory drug (NSAID), after a Europe-wide review of cardiovascular safety. While it has been known for some time that NSAIDs may increase the risk of cardiovascular events, the evidence base has become clearer. Diclofenac is associated with a significantly higher risk of cardiovascular events compared to other NSAIDs. Therefore, it is contraindicated in patients with ischaemic heart disease, peripheral arterial disease, cerebrovascular disease, and congestive heart failure (New York Heart Association classification II-IV). Patients should switch from diclofenac to other NSAIDs such as naproxen or ibuprofen, except for topical diclofenac. Studies have shown that naproxen and low-dose ibuprofen have the best cardiovascular risk profiles of the NSAIDs.

The MHRA’s updated guidance on diclofenac and cardiovascular safety highlights the increased risk of cardiovascular events associated with this NSAID compared to other NSAIDs. Patients with certain conditions are advised to avoid diclofenac and switch to other NSAIDs. This guidance is important for healthcare professionals to consider when prescribing NSAIDs to patients with cardiovascular risk factors.

Differentiating Reactive Arthritis from Other Arthritic Conditions

Reactive arthritis is a type of arthritis that occurs after an infection, typically dysentery or a sexually transmitted disease. It is characterized by an acute, asymmetrical lower limb arthritis, with common symptoms including enthesitis, sacroiliitis, and spondylosis. Patients may also experience mouth ulcers, conjunctivitis, and cutaneous features such as circinate balanitis and keratoderma blenorrhagia. However, it is important to differentiate reactive arthritis from other arthritic conditions such as disseminated bacterial arthritis, rheumatoid arthritis, ankylosing spondylitis, and hypersensitivity vasculitis. Understanding the unique features of each condition can aid in accurate diagnosis and appropriate treatment.
