Question 1
Correct

A 40-year-old woman with amyotrophic lateral sclerosis is in a meeting with her clinical team to discuss her ongoing care. The team notes that she has been experiencing weight loss and increased fatigue. The patient reports struggling with chewing and swallowing food, even when it has been mashed or pureed. What is the most suitable long-term management plan for this patient?
Your Answer: Insert a percutaneous gastrostomy tube
Explanation:The most appropriate way to provide nutritional support for patients with motor neuron disease is through the insertion of a percutaneous gastrostomy (PEG) tube. If a patient is struggling to feed themselves, they may initially benefit from smaller, more liquid-like meals, but if this is not sufficient, a PEG tube is a definitive long-term management option. Continuing with their current diet regimen is not recommended as it may lead to poor nutrition and a risk of aspiration. Total parenteral nutrition is only used as a last resort when there is impaired nutrient absorption. Inserting a nasogastric tube is not a suitable option as it must be removed after a few weeks to avoid adverse effects. A percutaneous jejunostomy tube is also not recommended as it is less commonly used and harder to maintain than a PEG tube.
Managing Motor Neuron Disease
Motor neuron disease is a neurological condition that affects both upper and lower motor neurons. It typically presents after the age of 40 and can manifest in different patterns, such as amyotrophic lateral sclerosis, progressive muscular atrophy, and bulbar palsy. The cause of the disease is unknown.
One medication used in the management of motor neuron disease is riluzole, which works by preventing the stimulation of glutamate receptors. It is mainly used in cases of amyotrophic lateral sclerosis and has been shown to prolong life by approximately three months.
Respiratory care is also an important aspect of managing motor neuron disease. Non-invasive ventilation, usually in the form of BIPAP, is used at night and has been associated with a survival benefit of around seven months.
Nutrition support is also crucial in managing motor neuron disease. The preferred method is percutaneous gastrostomy tube (PEG), which has been linked to prolonged survival.
Unfortunately, the prognosis for motor neuron disease is poor, with 50% of patients dying within three years.

What is a not a cause of hypertension in adolescents?
Your Answer: Bartter's syndrome
Explanation:Bartter’s syndrome is a genetic condition that typically follows an autosomal recessive pattern of inheritance. It results in severe hypokalaemia due to a defect in the absorption of chloride at the Na+ K+ 2Cl- cotransporter in the ascending loop of Henle. Unlike other endocrine causes of hypokalaemia such as Conn’s, Cushing’s and Liddle’s syndrome, Bartter’s syndrome is associated with normotension. The condition usually presents in childhood and is characterized by symptoms such as failure to thrive, polyuria, polydipsia, hypokalaemia, and weakness.
Hypertension, or high blood pressure, can also affect children. To measure blood pressure in children, it is important to use a cuff size that is approximately 2/3 the length of their upper arm. The 4th Korotkoff sound is used to measure diastolic blood pressure until adolescence, when the 5th Korotkoff sound can be used. Results should be compared with a graph of normal values for their age.
In younger children, secondary hypertension is the most common cause, with renal parenchymal disease accounting for up to 80% of cases. Other causes of hypertension in children include renal vascular disease, coarctation of the aorta, phaeochromocytoma, congenital adrenal hyperplasia, and essential or primary hypertension, which becomes more common as children get older. It is important to identify the underlying cause of hypertension in children in order to provide appropriate treatment and prevent complications.

As a doctor in the emergency department, you encounter a 42-year-old man who complains of new left leg tingling and weakness. He reports that three days ago he was independent and walking normally. The patient has a medical history of type 2 diabetes mellitus and takes insulin.
Upon examination, the patient has a heart rate of 121 beats per minute, a blood pressure of 101/72 mmHg, and a temperature of 38.3ºC. The right leg has 4/5 power throughout, while sensation is altered over the right anterior thigh and knee. The left leg has 4/5 power in hip flexion and extension, 3/5 power in knee flexion, knee extension, and ankle dorsiflexion, and 0/5 power in great toe extension and plantarflexion. Sensation is altered on the left over the thigh and knee, but absent to both light touch and pin prick in the left foot.
What is the most likely diagnosis for this patient?Your Answer: Lumbar discitis with pathological fracture
Correct Answer: Lumbar epidural abscess
Explanation:The patient is displaying signs of sepsis and a developing neurological deficit in their lower limbs, which could indicate the presence of an epidural abscess. This is particularly likely given the patient’s history of diabetes, which is a known risk factor for this condition. While a diabetic foot can also cause neurological deficits and sepsis, the distribution of symptoms would be different and not affect the proximal limb on the opposite side. Discitis with a pathological fracture is also a possibility, but the absence of pain makes this less likely. Intracranial pathology is unlikely as the neurological deficit is confined to the lower limbs and there are no other systemic neurological symptoms present.
Understanding Discitis: Causes, Symptoms, Diagnosis, and Treatment
Discitis is a condition characterized by an infection in the intervertebral disc space, which can lead to serious complications such as sepsis or an epidural abscess. The most common cause of discitis is bacterial, with Staphylococcus aureus being the most frequent culprit. However, it can also be caused by viral or aseptic factors. The symptoms of discitis include back pain, pyrexia, rigors, and sepsis. In some cases, neurological features such as changing lower limb neurology may occur if an epidural abscess develops.
To diagnose discitis, imaging tests such as MRI are used due to their high sensitivity. A CT-guided biopsy may also be required to guide antimicrobial treatment. The standard therapy for discitis involves six to eight weeks of intravenous antibiotic therapy. The choice of antibiotic depends on various factors, with the most important being the identification of the organism through a positive culture, such as a blood culture or CT-guided biopsy.
Complications of discitis include sepsis and epidural abscess. Therefore, it is essential to assess the patient for endocarditis, which can be done through transthoracic echo or transesophageal echo. Discitis is usually due to haematogenous seeding of the vertebrae, which implies that the patient has had a bacteraemia, and seeding could have occurred elsewhere. Understanding the causes, symptoms, diagnosis, and treatment of discitis is crucial in managing this condition and preventing its complications.

A 36-year-old woman arrives at the emergency department complaining of sudden abdominal pain and vaginal bleeding. She has a medical history of complicated pelvic inflammatory disease that resulted in scarring of her right fallopian tube. Her last menstrual period was six weeks ago. Upon examination, her heart rate is 93 bpm, and her blood pressure is 136/76 mmHg. Palpation of the left iliac fossa causes pain. A urinary pregnancy test confirms her pregnancy, and further investigations reveal a 45 mm left adnexal mass with no heartbeat detected. Her serum b-hCG level is 5200 IU/L. What is the most appropriate course of action for her treatment?
Your Answer: Laparoscopic salpingectomy and monitoring
Correct Answer: Laparoscopic salpingotomy and monitoring
Explanation:For women with risk factors for infertility, such as contralateral tube damage, salpingotomy should be considered as the preferred surgical management for ectopic pregnancy. In the case of this patient, who presented with acute-onset abdominal pain and vaginal bleeding 6-8 weeks after her last period, a positive pregnancy test, and ultrasound findings confirming ectopic pregnancy, surgical intervention is necessary. Given the size of the ectopic pregnancy and beta-hCG levels, either laparoscopic salpingectomy or salpingotomy is appropriate. However, since the patient has a history of PID and scarring of the contralateral tube, salpingotomy is the preferred option as it preserves the affected tube and her fertility. Expectant management, laparoscopic salpingectomy, and medical management with methotrexate are not appropriate for this patient’s case.
Ectopic pregnancy is a serious condition that requires prompt investigation and management. Women who are stable are typically investigated and managed in an early pregnancy assessment unit, while those who are unstable should be referred to the emergency department. The investigation of choice for ectopic pregnancy is a transvaginal ultrasound, which will confirm the presence of a positive pregnancy test.
There are three ways to manage ectopic pregnancies: expectant management, medical management, and surgical management. The choice of management will depend on various criteria, such as the size of the ectopic pregnancy, whether it is ruptured or not, and the patient’s symptoms and hCG levels. Expectant management involves closely monitoring the patient over 48 hours, while medical management involves giving the patient methotrexate and requires follow-up. Surgical management can involve salpingectomy or salpingotomy, depending on the patient’s risk factors for infertility.
Salpingectomy is the first-line treatment for women with no other risk factors for infertility, while salpingotomy should be considered for women with contralateral tube damage. However, around 1 in 5 women who undergo a salpingotomy require further treatment, such as methotrexate and/or a salpingectomy. It is important to carefully consider the patient’s individual circumstances and make a decision that will provide the best possible outcome.

How many units of alcohol are in a 750ml bottle of red wine with an alcohol by volume of 12%?
Your Answer: 10 units
Correct Answer: 9 units
Explanation:To calculate alcohol units, multiply the volume in milliliters by the alcohol by volume (ABV) and divide by 1,000.
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.

A 40-year-old man complains of pain in his right eye that worsens with movement. Upon examination, a relative afferent pupillary defect is observed. What is the most probable reason for his symptoms?
Your Answer: Multiple sclerosis
Explanation:Optic neuritis is a condition that can be caused by multiple sclerosis, diabetes, or syphilis. It is characterized by a decrease in visual acuity in one eye over a period of hours or days, as well as poor color discrimination and pain that worsens with eye movement. Other symptoms include a relative afferent pupillary defect and a central scotoma. The condition can be diagnosed through an MRI of the brain and orbits with gadolinium contrast. Treatment typically involves high-dose steroids, and recovery usually takes 4-6 weeks. If an MRI shows more than three white-matter lesions, the risk of developing multiple sclerosis within five years is approximately 50%.

A 32-year-old woman is brought to the Emergency Department after fainting. She is now conscious and able to provide a medical history. The patient mentions having a condition, but cannot recall the name. She shows the doctor the medication she takes, which is a somatostatin analogue.
What medical condition can be treated with somatostatin analogues?Your Answer: Acromegaly
Explanation:Acromegaly is a condition caused by excessive secretion of growth hormone from an anterior pituitary tumor, resulting in enlarged hands, feet, and jaw, as well as other symptoms. While surgery is the preferred treatment, somatostatin analogues such as octreotide and lanreotide can be used if surgery fails. Somatostatin is an inhibitory hormone that can suppress growth hormone release. However, it can also cause side effects such as bradycardia, hypothyroidism, and hypoglycemia. Cushing’s disease, caused by excess adrenocorticotropic hormone, can be treated with pituitary gland removal, radiotherapy, or cortisol-inhibiting medications. Conn syndrome, or primary aldosteronism, is usually treated with surgery. Type I diabetes is treated with insulin, while Type II diabetes is treated with insulin and oral hypoglycemic agents. Parathyroid adenomas are also treated surgically.

An 88-year-old woman visits her doctor with her daughter. She was diagnosed with Alzheimer's dementia two years ago and has recently moved in with her daughter for care. Lately, she has become increasingly isolated and has reported seeing animals in the house that are not actually there. She denies any other symptoms. All vital signs are normal and physical examination is unremarkable.
What is the probable cause of her current symptoms?Your Answer: Delirium
Explanation:Cognitively impaired patients can experience delirium when placed in new surroundings. Even minor changes in environment can trigger delirium in individuals with dementia, leading to visual hallucinations. While community-acquired pneumonia and urinary tract infections are common causes of delirium in the elderly, they seem unlikely in this case as there are no other clues in the history or examination. Depression is a common differential for dementia in the elderly, but the acute onset of symptoms in this woman suggests delirium. It is important to note that symptoms of depression in the elderly can be non-specific. While psychosis could explain the visual hallucinations, the absence of other symptoms and the acute onset of the condition suggest delirium.
Acute confusional state, also known as delirium or acute organic brain syndrome, is a condition that affects up to 30% of elderly patients admitted to hospital. It is more common in patients over the age of 65, those with a background of dementia, significant injury, frailty or multimorbidity, and those taking multiple medications. The condition is often triggered by a combination of factors, such as infection, metabolic imbalances, change of environment, and underlying medical conditions.
The symptoms of acute confusional state can vary widely, but may include memory disturbances, agitation or withdrawal, disorientation, mood changes, visual hallucinations, disturbed sleep, and poor attention. Treatment involves identifying and addressing the underlying cause, modifying the patient’s environment, and using sedatives such as haloperidol or olanzapine. However, managing the condition can be challenging in patients with Parkinson’s disease, as antipsychotics can worsen Parkinsonian symptoms. In such cases, careful reduction of Parkinson medication may be helpful, and atypical antipsychotics such as quetiapine and clozapine may be preferred for urgent treatment.
Overall, acute confusional state is a complex condition that requires careful management and individualized treatment. By addressing the underlying causes and providing appropriate sedation, healthcare professionals can help patients recover from this condition and improve their overall quality of life.

A 25-year-old man presents to his doctor with a complaint of a lump in his testicle. During the examination, the lump disappears when he lies down. The scrotum shows dilated veins, while the abdominal examination is unremarkable. He expresses concern about his inability to conceive despite trying. What is the most probable diagnosis?
Your Answer: Varicocoele
Explanation:Common Causes of Testicular Lumps: Varicocele, Epididymitis, Hydrocele, Inguinal Hernia, and Testicular Teratoma
Testicular lumps can be a cause for concern and require medical attention. Here are some common causes of testicular lumps:
Varicocele: This is a painless swelling of the testes on the left side, which can be described as a bag of worms within the spermatic cord above the testis. It tends to occur in those aged 12+ years and is rare in pre-pubertal boys. Varicoceles are associated with male infertility, and a quarter of men with abnormal semen parameters will have a varicocele.
Epididymitis: This is inflammation of the testis and epididymis caused by infection such as chlamydia infection, gonorrhoea, mumps, bacterial coliforms or syphilis. It may present as acute testicular pain, swelling and tenderness, and associated symptoms include urethritis, increased urinary frequency and dysuria. Systemic symptoms may include fever and rigors.
Hydrocele: This is a non-tender, painless, cystic scrotal swelling below and anterior to the testes. It will normally transilluminate and does not tend to reduce on lying flat. Although hydroceles can fluctuate in size and are affected by movement, they are not usually a cause for concern.
Inguinal hernia: This is a condition where a part of the intestine or other tissue protrudes through a weak spot in the abdominal muscles, causing a lump in the groin or scrotum. If reducible, the lump may disappear on lying flat.
Testicular teratoma: This is a solid testicular lump within the testis, which is suggestive of a tumour. Testicular cancers can be subdivided into seminomas, teratomas and yolk-sac tumours. Over 95% of testicular cancers arise from the germ cells. Teratomas typically present at age 20–30 years, whereas seminomas typically present at age 35–45 years.

A 65-year-old man with a history of lung cancer presents with a three-week history of loss of appetite, nausea, and fatigue. He appears mildly dehydrated on examination. You order some blood tests and the results are as follows:
Calcium 3.12 mmol/l
Albumin 40 g/l
Glucose (random) 6.7 mmol/l
Urea 10.2 mmol/l
Creatinine 115 µmol/l
Which medication that he is currently taking is most likely contributing to his symptoms?Your Answer: Amlodipine
Correct Answer: Bendroflumethiazide
Explanation:Hypercalcaemia is caused by thiazides.
Understanding the Causes of Hypercalcaemia
Hypercalcaemia is a medical condition characterized by high levels of calcium in the blood. In most cases, two conditions account for 90% of hypercalcaemia cases. The first is primary hyperparathyroidism, which is the most common cause in non-hospitalized patients. The second is malignancy, which is the most common cause in hospitalized patients. Malignancy-related hypercalcaemia may be due to various processes, including PTHrP from the tumor, bone metastases, and myeloma. For this reason, measuring parathyroid hormone levels is crucial when investigating patients with hypercalcaemia.
Other causes of hypercalcaemia include sarcoidosis, tuberculosis, histoplasmosis, vitamin D intoxication, acromegaly, thyrotoxicosis, milk-alkali syndrome, drugs such as thiazides and calcium-containing antacids, dehydration, Addison’s disease, and Paget’s disease of the bone. It is important to note that hypercalcaemia may occur with prolonged immobilization in patients with Paget’s disease of the bone, although this condition is usually normal.
In summary, hypercalcaemia can be caused by various medical conditions, with primary hyperparathyroidism and malignancy being the most common. Measuring parathyroid hormone levels is essential in investigating patients with hypercalcaemia. Other causes of hypercalcaemia include sarcoidosis, tuberculosis, histoplasmosis, vitamin D intoxication, acromegaly, thyrotoxicosis, milk-alkali syndrome, drugs, dehydration, Addison’s disease, and Paget’s disease of the bone.

Question 11

A 49-year-old homeless man has been admitted to the emergency department after collapsing with sudden onset left side hemiparesis and facial droop. A CT scan has revealed a large intracerebral haemorrhage, which is likely to have occurred spontaneously. The patient's medical and family history is unknown, but you suspect that coagulopathy may be the cause of the spontaneous bleed. The clotting profile and specific clotting factor levels are as follows:
- PT prolonged
- APTT prolonged
- Factor VIII high
- Factor II low
- Factor V low
- Factor VII low
- Factor IX low
- Von Willebrand factor high
What is the most probable reason for the coagulopathy?Your Answer: Haemophilia A
Correct Answer: Liver failure
Explanation:It is highly probable that the individual is suffering from liver failure as all clotting factors, except for factor VIII, are below normal levels. In cases of liver failure, both PT and APTT may be prolonged. Haemophilia A and B are unlikely as they result in deficiencies of specific clotting factors, whereas Von Willebrand disease may have low levels of Von Willebrand factor but the other factors remain unaffected. Disseminated intravascular coagulation, on the other hand, leads to depletion of all clotting factors.
Coagulopathy in Liver Disease: Paradoxical Supra-normal Factor VIII and Increased Thrombosis Risk
In liver failure, the levels of all clotting factors decrease except for factor VIII, which paradoxically increases. This is because factor VIII is synthesized not only in hepatic endothelial cells but also in endothelial cells throughout the body. Moreover, good hepatic function is required for the rapid clearance of activated factor VIII from the bloodstream, leading to further increases in circulating factor VIII. Despite conventional coagulation studies suggesting an increased risk of bleeding, patients with chronic liver disease are paradoxically at an increased risk of thrombosis formation. This is due to several factors, including reduced synthesis of natural anticoagulants such as protein C, protein S, and anti-thrombin, which are all essential for preventing thrombosis.

A 5-year-old boy presents to the emergency department with generalised facial swelling. He recently recovered from viral pharyngitis. He is otherwise healthy and meeting developmental milestones.
Upon examination, he is alert and not experiencing any respiratory distress. There is pitting edema in his face and legs.
Urinalysis reveals 4+ protein and no hematuria. Blood tests show a hemoglobin level of 180 g/L (normal range for males: 135-180, females: 115-160), platelets at 450 * 109/L (normal range: 150-400), WBC at 8.0 * 109/L (normal range: 4.0-11.0), bilirubin at 12 µmol/L (normal range: 3-17), ALP at 60 u/L (normal range: 30-100), ALT at 35 u/L (normal range: 3-40), γGT at 32 u/L (normal range: 8-60), and albumin at 10 g/L (normal range: 35-50).
What is the recommended first-line treatment option for this likely diagnosis?Your Answer:
Correct Answer: Prednisolone
Explanation:The most appropriate treatment for minimal change glomerulonephritis, which is likely the cause of this patient’s facial edema, hypoalbuminemia, and proteinuria, is prednisolone. This medication is a corticosteroid and is considered the mainstay of therapy for this condition. Adrenaline, albumin infusion, and furosemide are not appropriate treatments for this patient’s condition. While albumin infusion may be used as adjunctive therapy, its effects will only be temporary. Adrenaline is used to treat anaphylaxis and would not be effective in treating minimal change disease. Furosemide may be used as adjunctive therapy, but its effects will also be temporary.
Minimal change disease is a condition that typically presents as nephrotic syndrome, with children accounting for 75% of cases and adults accounting for 25%. While most cases are idiopathic, around 10-20% have a known cause, such as certain drugs, Hodgkin’s lymphoma, thymoma, or infectious mononucleosis. The pathophysiology of the disease involves T-cell and cytokine-mediated damage to the glomerular basement membrane, resulting in polyanion loss and reduced electrostatic charge, which increases glomerular permeability to serum albumin. The disease is characterized by nephrotic syndrome, normotension (hypertension is rare), and highly selective proteinuria, with only intermediate-sized proteins such as albumin and transferrin leaking through the glomerulus. Renal biopsy shows normal glomeruli on light microscopy, but electron microscopy reveals fusion of podocytes and effacement of foot processes.
Management of minimal change disease typically involves oral corticosteroids, which are effective in 80% of cases. For steroid-resistant cases, cyclophosphamide is the next step. The prognosis for the disease is generally good, although relapse is common. Approximately one-third of patients have just one episode, one-third have infrequent relapses, and one-third have frequent relapses that stop before adulthood.

A 72-year-old man visits his General Practitioner for his annual medication review. He has hypertension and gout and is currently taking allopurinol 300 mg, amlodipine 10 mg and atorvastatin 20 mg. His home blood pressure readings average at 150/88 mmHg. His recent blood tests of glycosylated haemoglobin (HbA1c), renal profile and lipids are normal. Which of the following medications would be the most appropriate to add to his current regime?
Your Answer:
Correct Answer: Ramipril
Explanation:The patient’s hypertension is not well controlled despite being on the maximum dose of a calcium-channel blocker. According to NICE guidance, the next step in treatment should be a thiazide-like diuretic or an ACE inhibitor. However, as the patient has a history of recurrent gout, a diuretic is not advisable, and an ACE inhibitor such as ramipril is the most appropriate choice.
Aspirin 75 mg was previously recommended for primary prevention of cardiovascular disease in patients with multiple risk factors. However, current advice is to only consider prescribing aspirin after a careful risk assessment in patients with a high risk of stroke or myocardial infarction. Routine prescribing of antiplatelets for primary prevention is no longer recommended due to the risk of gastrointestinal bleed outweighing the benefits.
NICE no longer recommends initiating thiazide diuretics for hypertension treatment. Patients already established on this medication and whose BP is well controlled should continue. However, thiazide-like diuretics or ACE inhibitors are preferred as second-line treatment for hypertension in patients already on a calcium-channel blocker.
Diltiazem and amlodipine are both calcium-channel blockers, and medication from a different class of antihypertensives should be added.
Indapamide is a thiazide-like diuretic recommended as a second-line treatment for hypertension not controlled on the maximum dose of a calcium-channel blocker. However, as the patient has a history of recurrent gout, which can be exacerbated by thiazide and thiazide-like diuretics, an ACE inhibitor would be a more suitable choice.

A woman with a history of asthma who is 25 weeks pregnant is found to have consistent blood pressure readings >170/95 mmHg. She is admitted under Gynaecology.
Which of the following antihypertensives would you initiate for this patient?Your Answer:
Correct Answer: Nifedipine
Explanation:Safe and Effective Treatment Options for Gestational Hypertension
Gestational hypertension is a serious condition that requires prompt medical attention. According to NICE guidelines, labetalol is the first-line treatment for gestational hypertension. However, if the patient has asthma, labetalol is contraindicated. In such cases, nifedipine is listed as the second-line treatment, followed by methyldopa if necessary.
Diltiazem is not usually used in gestational hypertension, and the role of this medication in pregnancy is unclear. Bendroflumethiazide is relatively contraindicated in pregnancy, while ACE inhibitors and ARBs are absolutely contraindicated due to their potential adverse effects on fetal blood pressure and renal function.
In cases of gestational hypertension, it is crucial to rule out pre-eclampsia. If the patient’s blood pressure is above 160/110, NICE guidelines recommend admission until the blood pressure is below this level.
Calcium channel blockers, such as nifedipine, are safe and effective in pregnancy, while the role of diltiazem is uncertain. Bendroflumethiazide is relatively contraindicated, while ACE inhibitors and ARBs are absolutely contraindicated. It is essential to choose the appropriate medication based on the patient’s medical history and individual circumstances.

According to the Keith-Wagener-Barker classification of hypertensive retinopathy, what grade of hypertensive retinopathy is this?Your Answer:
Correct Answer: Grade 3
Explanation:Stages of Diabetic Retinopathy
Diabetic retinopathy is a condition that affects the eyes of people with diabetes. It is important to detect and treat it early to prevent vision loss. There are different stages of diabetic retinopathy, each with its own set of features.
Grade 1 is characterized by arteriolar narrowing. Grade 2 includes features of grade 1 and arteriovenous nipping. Grade 3 includes features of grade 2 and microaneurysms, dot-and-blot haemorrhages, flame-shaped haemorrhages, cotton-wool spots, and hard exudates. Grade 4 includes features of grade 3 and optic disc swelling.
It is important to have regular eye exams if you have diabetes to detect any signs of diabetic retinopathy early. With proper management and treatment, vision loss can be prevented or delayed.

A 32-year-old woman visits her doctor worried that she may have been in contact with a child who has chickenpox. She is currently 20 weeks pregnant and unsure if she has ever had chickenpox before. Upon examination, no rash is present. Her blood test results show that she is Varicella Zoster IgG negative. What is the best course of action to take next?
Your Answer:
Correct Answer: Give varicella-zoster immunoglobulin (VZIG)
Explanation:If a pregnant woman is exposed to chickenpox before 20 weeks and has a negative IgG test, it indicates that she is not immune to the virus or has not been previously exposed to it. In such cases, it is recommended to administer varicella-zoster immunoglobulin (VZIG) as soon as possible, which can be effective up to 10 days after exposure. It is not necessary to inform public health as chickenpox is not a notifiable disease.
If a pregnant woman develops a chickenpox rash, VZIG has no therapeutic benefit and should not be used. However, antiviral agents like aciclovir can be given within 24 hours of the rash onset. It is important to note that antiviral agents are recommended for post-exposure prophylaxis for immunosuppressed individuals.
Women who are not immune to varicella-zoster can receive the vaccine before pregnancy or after delivery, but it should not be administered during pregnancy. Therefore, option D cannot be correct in any situation.
Chickenpox exposure in pregnancy can pose risks to both the mother and fetus, including fetal varicella syndrome. Post-exposure prophylaxis (PEP) with varicella-zoster immunoglobulin (VZIG) or antivirals should be given to non-immune pregnant women, with timing dependent on gestational age. If a pregnant woman develops chickenpox, specialist advice should be sought and oral aciclovir may be given if she is ≥ 20 weeks and presents within 24 hours of onset of the rash.

Explanation:Understanding Anticoagulation Treatment for Atrial Fibrillation: A CHADS-VASc Scoring System Overview
Atrial fibrillation (AF) is a common rhythm disturbance that can increase the risk of stroke. To determine the appropriate treatment for primary prevention of stroke, healthcare professionals use the CHADS-VASc scoring system. This system assigns points based on various risk factors, including age, sex, hypertension, diabetes, previous stroke or transient ischemic attack, and vascular disease.
This score is based on a point system in which 2 points are assigned for a history of stroke or transient ischemic attack or age 75 years or more and 1 point each is assigned for age 65 to 74 years; a history of hypertension, diabetes, recent cardiac failure, vascular disease (myocardial infarction, complex aortic plaque, and peripheral arterial disease (PAD), including prior revascularization, amputation due to PAD, or angiographic evidence of PAD, etc.); and female gender, resulting in a maximum score of 9 points.
Score Risk Anticoagulation Therapy 0 (male) or 1 (female) Low No anticoagulant therapy 1 (male) Moderate Oral anticoagulant should be considered 2 or greater High Oral anticoagulant is recommended Aspirin is not recommended for primary prevention of stroke in patients with AF, but may be used for secondary prevention after a stroke. Clexane, a low-molecular-weight heparin, is not used for long-term treatment of AF. Dipyridamole may be used in combination with clopidogrel or aspirin for stroke treatment, but not for prevention in AF patients.
It is important to accurately identify AF and assess the patient’s risk using the CHADS-VASc scoring system to determine the appropriate anticoagulation treatment. NOACs are only licensed for non-valvular AF, so patients with valvular AF should be treated with warfarin or seek advice from a specialist.

A 35-year-old woman came to your GP clinic with a cold sore and left eye discomfort. She reported experiencing a red, painful eye with watering and sensitivity to light for the past 3 days. During fluorescein examination, you observed a dendritic ulcer on the cornea that was stained with fluorescein.
What is the primary treatment for this condition?Your Answer:
Correct Answer: Topical aciclovir drops
Explanation:The appropriate treatment for herpes simplex keratitis is the use of topical aciclovir. Antibiotics are ineffective against viral infections and should not be used. The use of steroids can worsen the condition and should be avoided. If the patient is already using topical steroids for another eye condition, the dosage should be decreased.
Understanding Herpes Simplex Keratitis
Herpes simplex keratitis is a condition that affects the cornea of the eye and is caused by the herpes simplex virus. The most common symptom of this condition is a dendritic corneal ulcer, which can cause a red, painful eye, photophobia, and epiphora. In some cases, visual acuity may also be decreased. Fluorescein staining may show an epithelial ulcer, which can help with diagnosis. One common treatment for this condition is topical aciclovir, which can help to reduce the severity of symptoms and prevent further damage to the cornea.

A 29 week pregnant woman presents to her GP with a rash that has developed over the past 12 hours. Upon examination, lesions indicative of chickenpox are observed. The patient's vital signs are stable and she appears to be in good health. What course of action is recommended for management?
Your Answer:
Correct Answer: Oral aciclovir
Explanation:Pregnant women who contract chickenpox after 20 weeks of gestation should seek medical attention immediately. This is because chickenpox can lead to serious complications such as pneumonia, hepatitis, and encephalitis. Treatment with oral aciclovir is recommended if the woman presents within 24 hours of developing the rash. Aciclovir can help reduce the duration of fever and other symptoms. Symptomatic treatment can also be used alongside aciclovir. If the chickenpox is severe, the woman should be referred to the hospital for intravenous aciclovir. Additionally, a referral to fetal medicine may be necessary due to the small risk of fetal varicella syndrome in the first 28 weeks of pregnancy. It is important to advise anyone with chickenpox to avoid contact with pregnant women and neonates until all lesions have crusted over, which usually takes about 5 days after the onset of the rash. VZIG has no therapeutic benefit once the rash has started. These guidelines are based on the RCOG Greentop guidelines for chickenpox in pregnancy.
Chickenpox exposure in pregnancy can pose risks to both the mother and fetus, including fetal varicella syndrome. Post-exposure prophylaxis (PEP) with varicella-zoster immunoglobulin (VZIG) or antivirals should be given to non-immune pregnant women, with timing dependent on gestational age. If a pregnant woman develops chickenpox, specialist advice should be sought and oral aciclovir may be given if she is ≥ 20 weeks and presents within 24 hours of onset of the rash.

Question 20

An 80-year-old man with terminal lung cancer is evaluated by the palliative care team to determine his analgesic requirements. He is currently on a regimen of 30 mg slow-release morphine twice daily, which effectively manages his pain. However, he is experiencing difficulty swallowing both tablet and liquid forms of the medication. The palliative team suggests transitioning him to subcutaneous morphine. What is the appropriate daily dosage for him?
Your Answer:
Correct Answer: 30mg
Explanation: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.
