    Correct

    • A 3-year-old child with a history of atopic eczema presents to the clinic. The child's eczema is typically managed well with emollients, but the parents are worried as the facial eczema has worsened significantly overnight. The child now has painful blisters clustered on both cheeks, around the mouth, and on the neck. The child's temperature is 37.9ºC. What is the best course of action for management?

      Your Answer: Admit to hospital

      Explanation:

      IV antivirals are necessary for the treatment of eczema herpeticum, which is a severe condition.

      Understanding Eczema Herpeticum

      Eczema herpeticum is a serious skin infection caused by herpes simplex virus 1 or 2. It is commonly observed in children with atopic eczema and is characterized by a rapidly progressing painful rash. The infection can be life-threatening, which is why it is important to seek medical attention immediately.

      During examination, doctors typically observe monomorphic punched-out erosions, which are circular, depressed, and ulcerated lesions that are usually 1-3 mm in diameter. Due to the severity of the infection, children with eczema herpeticum should be admitted to the hospital for intravenous aciclovir treatment. It is important to understand the symptoms and seek medical attention promptly to prevent any complications.

    Correct

    • A 35-year-old woman is admitted for an endoscopic retrograde cholangiopancreatography (ERCP) due to biliary colic. She has an uneventful procedure but is re-admitted the same night with severe abdominal pain.
      On examination, she is tachycardic, short of breath, and has a pleural effusion on her chest X-ray (CXR).
      Investigations reveal the following:
      Investigation Result Normal value
      C-reactive protein (CRP) 180 mg/l < 10 mg/l
      White cell count (WCC) 15.0 × 109/l 4.0–11.0 × 109/l

      Corrected Calcium (Ca2+) 0.8 mmol/l 2.20–2.60 mmol/l
      What is her most likely diagnosis?

      Your Answer: Pancreatitis

      Explanation:

      Understanding Complications of ERCP: Pancreatitis, Cholangitis, and More

      ERCP (endoscopic retrograde cholangiopancreatography) is a common procedure used to diagnose and treat conditions of the bile ducts and pancreas. However, like any medical procedure, it carries risks and potential complications. One such complication is pancreatitis, which can present with non-specific symptoms but may be accompanied by hypocalcaemia. Immediate management includes confirming the diagnosis and severity of pancreatitis, intravenous fluid resuscitation, oxygen, and adequate analgesia. Another potential complication is ascending cholangitis, which can present with fever, jaundice, and abdominal pain. Biliary perforation is a serious but infrequent complication that is usually recognized during the procedure, while intestinal perforation is not an expected complication. A reaction to contrast would have occurred during the procedure. It is important to understand these potential complications and their symptoms in order to provide prompt and appropriate management.

    Correct

    • A 55-year-old man presented to his GP with two instances of painless visible haematuria. He was subsequently referred to urology for biopsy and flexible cystoscopy, which revealed a transitional cell carcinoma of the bladder. What is the most significant risk factor associated with this condition?

      Your Answer: Smoking

      Explanation:

      Risk Factors for Bladder Cancer

      Bladder cancer is a type of cancer that affects the bladder, and there are different types of bladder cancer. The most common type is urothelial (transitional cell) carcinoma, and the risk factors for this type of bladder cancer include smoking, exposure to aniline dyes, rubber manufacture, and cyclophosphamide. Smoking is the most important risk factor in western countries, with a hazard ratio of around 4. Exposure to aniline dyes, such as working in the printing and textile industry, can also increase the risk of bladder cancer. Rubber manufacture and cyclophosphamide are also risk factors for urothelial carcinoma.

      On the other hand, squamous cell carcinoma of the bladder has different risk factors. Schistosomiasis and smoking are the main risk factors for this type of bladder cancer. Schistosomiasis is a parasitic infection that can cause inflammation and damage to the bladder, which can increase the risk of developing squamous cell carcinoma. Smoking is also a risk factor for squamous cell carcinoma, as it can cause changes in the cells of the bladder lining that can lead to cancer.

      In summary, the risk factors for bladder cancer depend on the type of cancer. Urothelial carcinoma is mainly associated with smoking, exposure to aniline dyes, rubber manufacture, and cyclophosphamide, while squamous cell carcinoma is mainly associated with schistosomiasis and smoking. It is important to be aware of these risk factors and take steps to reduce your risk of developing bladder cancer.

    Correct

    • A 50-year-old female with a history of Sjogren's syndrome presents to the gastroenterology clinic with elevated liver function tests. She reports experiencing fatigue and itching that has worsened over the past 3 months. On physical examination, her abdomen is soft, nontender, and without any organ enlargement. Laboratory results show a low hemoglobin level, normal platelet count and white blood cell count, elevated bilirubin, alkaline phosphatase, and gamma-glutamyl transferase levels, and positive anti-mitochondrial antibodies. What is the initial treatment recommended to halt the progression of her liver disease?

      Your Answer: Ursodeoxycholic acid

      Explanation:

      Primary biliary cholangitis is a chronic liver disease that primarily affects middle-aged women. It is characterized by the destruction of small bile ducts in the liver, leading to cholestasis and liver damage. The disease is diagnosed through blood tests that measure levels of specific antibodies and liver enzymes, which are highly specific to the condition. Ursodeoxycholic acid is the preferred treatment for slowing disease progression and improving symptoms, while cholestyramine can be used to alleviate itching but does not affect disease progression. In cases of decompensated liver disease, such as when bilirubin levels exceed 100, liver transplantation may be an option. Although recurrence in the graft can occur, it is typically not a significant issue. While fat-soluble vitamins can be supplemented, they are not a primary treatment option.

      Primary Biliary Cholangitis: A Chronic Liver Disorder

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

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

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

    Correct

    • You receive a letter from an endocrinology consultant following a referral that you made for a 25 year old gentleman who has been newly diagnosed with hyperthyroidism. The consultant requests that you start the patient on carbimazole 15mg daily with a repeat thyroid function test (TFT) in 4 weeks. What is the most crucial advice to give the patient?

      Your Answer: Attend for urgent medical review if develops any symptoms of infection e.g. sore throat or fever

      Explanation:

      Understanding Carbimazole and Its Mechanism of Action

      Carbimazole is a medication used to manage thyrotoxicosis, a condition characterized by an overactive thyroid gland. It is typically administered in high doses for six weeks until the patient becomes euthyroid, or has a normal thyroid function. The drug works by blocking thyroid peroxidase, an enzyme responsible for coupling and iodinating the tyrosine residues on thyroglobulin, which ultimately reduces thyroid hormone production.

      In contrast to propylthiouracil, another medication used to treat thyrotoxicosis, carbimazole only has a central mechanism of action. Propylthiouracil, on the other hand, also has a peripheral action by inhibiting 5′-deiodinase, an enzyme that reduces peripheral conversion of T4 to T3.

      While carbimazole can be effective in managing thyrotoxicosis, it is not without its adverse effects. One of the most serious side effects is agranulocytosis, a condition characterized by a severe reduction in white blood cells. Additionally, carbimazole can cross the placenta, but may be used in low doses during pregnancy.

      Overall, carbimazole is a medication that can be effective in managing thyrotoxicosis, but it is important to be aware of its mechanism of action and potential adverse effects. Patients should always consult with their healthcare provider before starting any new medication.

    Correct

    • A 70-year-old man presented to the clinic with proximal muscle weakness and a cough lasting eight weeks. He also reported pain in the small joints of his hands and small haemorrhages in the nailfolds. On examination, there was no lymphadenopathy or clubbing, but bibasal crackles were heard. A chest radiograph revealed diffuse reticular infiltrates, and lung function tests showed a restrictive pattern. What is the most likely underlying cause of his interstitial lung disease?

      Your Answer: Polymyositis

      Explanation:

      Differential Diagnosis of Polymyositis: A Comparison with Other Connective Tissue Diseases

      Polymyositis is a systemic connective tissue disease that causes inflammation of the striated muscle and skin in the case of dermatomyositis. Patients typically present with muscle weakness, pain in the small joints of the fingers, and dermatitis. The disease is associated with HLA-B8 and HLA-DR3, and underlying malignancy is present in at least 5-8% of cases. Here, we compare polymyositis with other connective tissue diseases to aid in differential diagnosis.

      Rheumatoid arthritis (RA) is another systemic inflammatory disease that affects mainly the joints, in particular, the proximal interphalangeal joints, in a symmetrical fashion. Pulmonary fibrosis is a known complication of RA, and muscular weakness is also a possible feature. However, in RA, joint-related symptoms are typically more prominent than muscle weakness, making polymyositis a more likely diagnosis in cases of predominant muscle weakness.

      Cryptogenic fibrosing alveolitis, also known as idiopathic pulmonary fibrosis, presents with diffuse reticular infiltrates on chest radiographs and a restrictive pattern on lung function tests. However, the history of proximal muscle weakness and pain in the small joints of the hands does not fit with this diagnosis and suggests polymyositis instead.

      Systemic lupus erythematosus (SLE) is an autoimmune disorder that affects multiple systems in the body. While SLE would be in the differential diagnosis for polymyositis, the prominent proximal muscle weakness and the fact that the patient is a man (SLE affects women in 90% of cases) make polymyositis a more likely diagnosis.

      Ankylosing spondylitis (AS) is an inflammatory rheumatic disease that primarily affects the axial joints and entheses. AS can be associated with pulmonary fibrosis and produces a restrictive pattern on spirometry. However, the more prominent complaint of proximal muscle weakness and the involvement of the small joints of the hands make AS a less likely diagnosis in cases of predominant muscle weakness.

    Incorrect

    • A 35-year-old male is admitted to hospital after an overdose of paracetamol. He waited until his children had gone to school and his wife had left for work before taking 100 tablets. He did not drink any alcohol and rarely has any. He had taken annual leave from the steady job in a factory and had left a note. His wife had forgotten something so returned from work earlier than usual and found him semi-conscious.

      After treatment for his physical health he tells you that he does not regret the attempt but feels bad that he has put his children through enough seeing him in hospital. He is not religious. His wife is not very supportive of him and thinks he is 'attention-seeking'. He has no other family or friends locally. He has struggled with symptoms of depression for a number of months and has never sought help, but otherwise is physically well.

      During your assessment, you want to ascertain any protective factors.

      Which of the following is a protective factor in this case?

      Your Answer: Lack of alcohol consumed with the overdose

      Correct Answer: She has children at home

      Explanation:

      Completed suicide can be prevented by certain protective factors such as having social support, religious beliefs, having children at home, and regretting a previous attempt. It is important to note that the duration of mental illness is not a determining factor, but having a mental illness, especially depression, increases the risk. Alcohol misuse is also a risk factor, but in this scenario, the fact that the person does not drink much alcohol is not particularly protective. The individual in the scenario lacks social support and is not religious, making those options incorrect. However, having children present at home is a protective factor.

      Suicide Risk Factors and Protective Factors

      Suicide risk assessment is a common practice in psychiatric care, with patients being stratified into high, medium, or low risk categories. However, there is a lack of evidence on the positive predictive value of individual risk factors. A review in the BMJ concluded that such assessments may not be useful in guiding decision-making, as 50% of suicides occur in patients deemed low risk. Nevertheless, certain factors have been associated with an increased risk of suicide, including male sex, history of deliberate self-harm, alcohol or drug misuse, mental illness, depression, schizophrenia, chronic disease, advancing age, unemployment or social isolation, and being unmarried, divorced, or widowed.

      If a patient has attempted suicide, there are additional risk factors to consider, such as efforts to avoid discovery, planning, leaving a written note, final acts such as sorting out finances, and using a violent method. On the other hand, there are protective factors that can reduce the risk of suicide, such as family support, having children at home, and religious belief. It is important to consider both risk and protective factors when assessing suicide risk and developing a treatment plan.

      Your Answer: 34-year-old female with a 4 week history of a new breast lump. Benign in nature on examination

      Correct Answer: 28-year-old female with a 8 week history of a new breast lump. Benign in nature on examination

      Explanation:

      According to NICE guidelines, women who are 30 years or older should be referred urgently to the local breast services if they have an unexplained breast lump with or without pain. As the woman in question is 28 years old, she should be referred to the local breast services, but it is not urgent.

      In 2015, NICE released guidelines for referring individuals suspected of having breast cancer. If a person is 30 years or older and has an unexplained breast lump with or without pain, or if they are 50 years or older and have discharge, retraction, or other concerning changes in one nipple only, they should be referred using a suspected cancer pathway referral for an appointment within two weeks. If a person has skin changes that suggest breast cancer or is 30 years or older with an unexplained lump in the axilla, a suspected cancer pathway referral should also be considered. For individuals under 30 years old with an unexplained breast lump with or without pain, non-urgent referral should be considered.

    Incorrect

    • A 5-year-old child is brought to the Paediatric department by his grandmother. He has developed a very high fever and is breathing with a high-pitched sound. His grandmother is very worried as she has tried to get him to drink some water and take paracetamol this morning, but he is drooling and refuses to take anything orally. The child is Spanish speaking, however, his grandmother translates that he feels too hot and his chest hurts.

      What is the most suitable initial step in managing this child's condition?

      Your Answer: IV hydrocortisone

      Correct Answer: Call anaesthetics

      Explanation:

      Acute epiglottitis is characterized by the sudden onset of fever, drooling, and stridor in a child. It is important to immediately call anaesthetics as there is a high risk of airway obstruction if the child becomes upset. The Hib vaccination is widely available and subsidized in many countries, including Poland where it has been available since the 1990s.

      Humidified oxygen is commonly used to manage bronchiolitis, but it should be avoided in patients with suspected epiglottitis as it may cause distress and worsen the airway obstruction. IV hydrocortisone is not a first-line treatment for epiglottitis and cannulating a patient before securing their airway or having anaesthetics present is not recommended.

      Nebulized salbutamol is useful for treating viral wheezing or asthma exacerbations, which present with an expiratory wheeze and fever, but not drooling. However, it should not be administered to a child with suspected epiglottitis until their airway is secured by anaesthetics to prevent further complications.

      Acute epiglottitis is a rare but serious infection caused by Haemophilus influenzae type B. It is important to recognize and treat it promptly as it can lead to airway obstruction. Although it was once considered a disease of childhood, it is now more common in adults in the UK due to the immunization program. The incidence of epiglottitis has decreased since the introduction of the Hib vaccine. Symptoms include a rapid onset, high temperature, stridor, drooling of saliva, and a tripod position where the patient leans forward and extends their neck to breathe easier. Diagnosis is made by direct visualization, but x-rays may be done to rule out a foreign body.

      Immediate senior involvement is necessary, including those who can provide emergency airway support such as anaesthetics or ENT. Endotracheal intubation may be necessary to protect the airway. It is important not to examine the throat if epiglottitis is suspected due to the risk of acute airway obstruction. The diagnosis is made by direct visualization, but only senior staff who are able to intubate if necessary should perform this. Treatment includes oxygen and intravenous antibiotics.

      Your Answer: Atopic eczema

      Correct Answer: Irritant dermatitis

      Explanation:

      Understanding Napkin Rashes and How to Manage Them

      Napkin rashes, also known as nappy rashes, are common skin irritations that affect babies and young children. The most common cause of napkin rash is irritant dermatitis, which is caused by the irritant effect of urinary ammonia and faeces. This type of rash typically spares the creases. Other causes of napkin rash include candida dermatitis, seborrhoeic dermatitis, psoriasis, and atopic eczema.

      To manage napkin rash, it is recommended to use disposable nappies instead of towel nappies and to expose the napkin area to air when possible. Applying a barrier cream, such as Zinc and castor oil, can also help. In severe cases, a mild steroid cream like 1% hydrocortisone may be necessary. If the rash is suspected to be candidal nappy rash, a topical imidazole should be used instead of a barrier cream until the candida has settled.

      Understanding the different types of napkin rashes and their causes is important in managing them effectively. By following these general management points, parents and caregivers can help prevent and alleviate napkin rashes in babies and young children.

    Correct

    • A 61-year-old man presents to the emergency department after experiencing syncope. Upon assessment, his respiratory rate is 20/min, heart rate is 170/min, and BP is 78/40 mmHg. An ECG reveals a regular tachycardia with a wide complex. The patient is given a peripheral venous line, blood is drawn, and an ECG monitor is attached. What is the next best course of action for managing this patient?

      Your Answer: DC cardioversion

      Explanation:

      Given the patient’s syncope, low BP, and regular wide complex tachycardia, which is likely to be ventricular tachycardia, the appropriate next step is DC cardioversion since the systolic BP is below 90 mmHg. Adenosine is not relevant in this scenario as it is used for managing narrow complex regular tachycardia with no adverse features. Amiodarone is an antiarrhythmic medication that could be used to treat ventricular tachycardia, but it is not appropriate in this case due to the patient’s syncope and low BP.

      Management of Peri-Arrest Tachycardias

      The Resuscitation Council (UK) guidelines for the management of peri-arrest tachycardias have been simplified in the 2015 update. The previous separate algorithms for broad-complex tachycardia, narrow complex tachycardia, and atrial fibrillation have been replaced by a unified treatment algorithm. After basic ABC assessment, patients are classified as stable or unstable based on the presence of adverse signs such as hypotension, pallor, sweating, confusion, or impaired consciousness. If any of these signs are present, synchronised DC shocks should be given, up to a maximum of three shocks.

      The treatment following this is based on whether the QRS complex is narrow or broad and whether the rhythm is regular or irregular. For broad-complex tachycardia, a loading dose of amiodarone followed by a 24-hour infusion is given if the rhythm is regular. If the rhythm is irregular, expert help should be sought as it could be due to atrial fibrillation with bundle branch block, atrial fibrillation with ventricular pre-excitation, or torsade de pointes.

      For narrow-complex tachycardia, vagal manoeuvres followed by IV adenosine are given if the rhythm is regular. If unsuccessful, atrial flutter is considered, and rate control is achieved with beta-blockers. If the rhythm is irregular, it is likely due to atrial fibrillation, and electrical or chemical cardioversion is considered if the onset is less than 48 hours. Beta-blockers are usually the first-line treatment for rate control unless contraindicated. The full treatment algorithm can be found on the Resuscitation Council website.

    Incorrect

    • Which of the following interventions is most likely to improve survival in individuals with COPD?

      Your Answer: Pulmonary rehabilitation

      Correct Answer: Long-term oxygen therapy

      Explanation:

      Long-term oxygen therapy is one of the few interventions that has been proven to enhance survival in COPD following smoking cessation.

      NICE guidelines recommend smoking cessation advice, annual influenza and one-off pneumococcal vaccinations, and pulmonary rehabilitation for COPD patients. Bronchodilator therapy is first-line treatment, with the addition of LABA and LAMA for patients without asthmatic features and LABA, ICS, and LAMA for those with asthmatic features. Theophylline is recommended after trials of bronchodilators or for patients who cannot use inhaled therapy. Azithromycin prophylaxis is recommended in select patients. Mucolytics should be considered for patients with a chronic productive cough. Loop diuretics and long-term oxygen therapy may be used for cor pulmonale. Smoking cessation and long-term oxygen therapy may improve survival in stable COPD patients. Lung volume reduction surgery may be considered in selected patients.

    Incorrect

    • A 68-year-old man is admitted for an elective total knee replacement (TKR).

      His past medical history includes type 2 diabetes mellitus (T2DM), which is well controlled with metformin 500mg BD and gliclazide 80 mg OD.

      The surgery is scheduled for the morning, but he is not placed on a variable rate insulin infusion (VRII).

      What adjustments should be made to his antidiabetic medication regimen on the day of surgery?

      Your Answer: Only the morning dose of metformin should be omitted

      Correct Answer: Only the morning dose of gliclazide should be omitted

      Explanation:

      On the day of surgery, it is recommended to omit the morning dose of gliclazide for patients taking sulfonylureas. However, if the patient takes BD, they can have the afternoon dose. Metformin should be taken as usual on the day before and on the day of elective surgery, except for lunchtime dose if taken three times a day.

      Preparation for surgery varies depending on whether the patient is undergoing an elective or emergency procedure. For elective cases, it is important to address any medical issues beforehand through a pre-admission clinic. Blood tests, urine analysis, and other diagnostic tests may be necessary depending on the proposed procedure and patient fitness. Risk factors for deep vein thrombosis should also be assessed, and a plan for thromboprophylaxis formulated. Patients are advised to fast from non-clear liquids and food for at least 6 hours before surgery, and those with diabetes require special management to avoid potential complications. Emergency cases require stabilization and resuscitation as needed, and antibiotics may be necessary. Special preparation may also be required for certain procedures, such as vocal cord checks for thyroid surgery or bowel preparation for colorectal cases.

    Correct

    • A 65-year-old man presents to the emergency department with a 12-day history of muscle cramping and fatigue. His blood tests and ECG are as follows:
      - Na+ 140 mmol/L (135 - 145)
      - K+ 3.7 mmol/L (3.5 - 5.0)
      - Bicarbonate 28 mmol/L (22 - 29)
      - Urea 6.2 mmol/L (2.0 - 7.0)
      - Creatinine 95 µmol/L (55 - 120)
      - Calcium 1.7 mmol/L (2.1-2.6)
      - Phosphate 1.3 mmol/L (0.8-1.4)
      - Magnesium 0.62 mmol/L (0.7-1.0)

      The patient's ECG shows a regular sinus rhythm with a rate of 72 BPM and a QTc of 480 ms. What is the most appropriate next step in management?

      Your Answer: Intravenous calcium gluconate

      Explanation:

      A 68-year-old man presents with hypocalcaemia and a prolonged QT interval, which can increase the risk of cardiac arrhythmias such as Torsades de pointes. Urgent intravenous calcium gluconate is the recommended treatment for severe hypocalcaemia, which can cause symptoms such as hand and foot spasming, tetany, and seizures. Checking the vitamin D level is important for identifying the cause of hypocalcaemia, but it is not the next best step in managing this patient’s acute condition. Oral calcium carbonate supplementation may be useful in some cases, but intravenous calcium is the preferred treatment for severe hypocalcaemia. Levothyroxine is not indicated for this patient, as hypothyroidism has not been diagnosed and urgent IV calcium gluconate should be given.

      Understanding Hypocalcaemia: Its Causes and Management

      Hypocalcaemia is a medical condition characterized by low levels of calcium in the blood. It can be caused by various factors such as vitamin D deficiency, chronic kidney disease, hypoparathyroidism, pseudohypoparathyroidism, rhabdomyolysis, magnesium deficiency, massive blood transfusion, and acute pancreatitis. In some cases, contamination of blood samples with EDTA may also lead to falsely low calcium levels.

      To manage severe hypocalcaemia, which may manifest as carpopedal spasm, tetany, seizures, or prolonged QT interval, intravenous calcium replacement is necessary. The preferred method is through the administration of intravenous calcium gluconate, with a recommended dose of 10ml of 10% solution over 10 minutes. However, it is important to note that intravenous calcium chloride may cause local irritation. ECG monitoring is also recommended during the treatment process. Further management of hypocalcaemia depends on the underlying cause.

      In summary, hypocalcaemia is a condition that can be caused by various factors, and its management depends on the severity of the symptoms and the underlying cause. Intravenous calcium replacement is the preferred method for severe cases, and ECG monitoring is recommended during treatment.

    Incorrect

    • A 27-year-old man presents to the Emergency Department complaining of sudden shortness of breath. He recently returned from a backpacking trip in Australia and was previously healthy. He denies any other symptoms and is stable hemodynamically. He has no personal or family history of cancer, heart failure, or chronic lung disease. A D-Dimer test is performed and comes back elevated. A subsequent CTPA reveals a small pulmonary embolism without any signs of right-sided heart strain. The consultant believes that he can be managed as an outpatient with a DOAC and close monitoring. Which of the following scoring systems can aid in their decision-making process?

      Your Answer: CHA2DS2-VASc

      Correct Answer: PESI

      Explanation:

      The PESI score is suggested by BTS guidelines for identifying patients with pulmonary embolism who can be treated as outpatients. It predicts long-term morbidity and mortality in PE patients. The ABCD2 is used for triaging acute Transient Ischaemic Attack cases. The CHA2DS2-VASc score aids in deciding whether to start prophylactic anticoagulation in atrial fibrillation patients. The GRACE score estimates mortality in those who have had Acute Coronary Syndrome.

      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.

He reports that his vision has been progressively worsening and he struggles with glare from oncoming vehicles. He also finds watching TV difficult and struggles to recognise his neighbour waving at him from across the street. He has had to have his glasses prescription changed three times in the past 18 months.
      What is the most likely diagnosis?

      Your Answer: Open angle glaucoma

      Correct Answer: Cataracts

      Explanation:

      Common Eye Conditions and Their Symptoms

      Cataracts: Gradual, painless reduced visual acuity, blurred vision, difficulty seeing at night-time, sensitivity to light due to glare and halos around light, inability to watch TV or recognise faces. Risk factors include increasing age, steroid use, alcohol excess, myotonic dystrophy, and diabetes. Treatment is with surgical replacement of the lens.

      Open Angle Glaucoma: Increased intraocular pressure resulting in visual field defects, loss of peripheral vision, seeing halos around lights, and tunnel vision. Patients may report bumping into things or not seeing cars in their periphery.

      Acute Closed Angle Glaucoma: Ophthalmological emergency presenting as a painful red eye, vomiting, headache, and reduced visual acuity. On examination, patients have a tender, hard eye with a semi-dilated, fixed pupil.

      Presbyopia: Age-related condition causing trouble focusing on close-up vision, often requiring reading glasses.

      Retinal Detachment: New-onset floaters and flashes, sudden-onset, painless visual field loss that may progress over hours to days, and a dark curtain or shadow over the field of vision in one eye only.

    Correct

    • You are the foundation year two doctor on the paediatric medical assessment unit. You are asked to clerk a 10-year-old boy who has been brought in by his father due to abdominal pain and strong smelling urine.

      A urine dip is positive for nitrites and leucocytes. You start treatment for a urinary tract infection. What is the most probable organism responsible for this infection?

      Your Answer: Escherichia coli

      Explanation:

      Escherichia coli is the most frequent organism responsible for UTIs in both children and adults. Streptococcus pneumonia is more commonly associated with pneumonia or otitis media, while Staphylococcus aureus is more likely to cause skin infections like impetigo. Herpes is a viral infection that causes oral or genital ulcerations and whitlow. Although not impossible, a fungal-induced UTI is unlikely.

      Investigating Urinary Tract Infections in Children

      When a child develops a urinary tract infection (UTI), it is important to consider the possibility of underlying causes and kidney damage. Unlike in adults, UTIs in children can lead to renal scarring. The National Institute for Health and Care Excellence (NICE) has provided guidelines for imaging the urinary tract in children with UTIs. Infants under six months of age who have their first UTI and respond to treatment should have an ultrasound within six weeks. However, children over six months of age who respond to treatment for their first UTI do not require imaging unless there are features suggestive of an atypical infection or recurrent infection.

      Features that suggest an atypical infection include being seriously ill, having poor urine flow, an abdominal or bladder mass, raised creatinine, septicemia, failure to respond to suitable antibiotics within 48 hours, or infection with non-E. coli organisms. If any of these features are present, further investigations may be necessary. Urine should be sent for microscopy and culture, as only 50% of children with a UTI have pyuria. A static radioisotope scan, such as DMSA, can identify renal scars and should be done 4-6 months after the initial infection. Micturating cystourethrography (MCUG) can identify vesicoureteric reflux and is only recommended for infants under six months of age who present with atypical or recurrent infections.

The patient is currently receiving treatment for hypertension and high cholesterol but is otherwise healthy and medically capable. The aneurysm was infra-renal and had a diameter of 4.9 cm.
      What is the best course of action for managing this patient?

      Your Answer: Ultrasound scan every two years

      Correct Answer: Ultrasound scan every three months

      Explanation:

      Screening and Management of Abdominal Aortic Aneurysms

      Abdominal aortic aneurysms (AAAs) are screened for initially by an ultrasound scan of the abdomen. Men are invited for an initial ultrasound during the year of their 65th birthday, while women are not routinely screened as AAA is predominantly found in men.

      If the initial scan shows an AAA of less than 3 cm, patients are discharged. If it is between 3 and 4.4 cm, they are invited back for yearly screening. If it is between 4.5 and 5.4 cm, patients receive an ultrasound scan every three months. If the aneurysm is above 5.5 cm, patients are referred to a vascular surgeon for consideration for repair.

      Elective surgery is recommended for aneurysms larger than 5.5 cm in diameter or those that are growing rapidly, as clinical trials have shown that the risk of rupture is increased when the aneurysm is larger than 5.5 cm. Immediate surgery is only performed on those aneurysms that are leaking or ruptured.

      Surveillance is required to ensure the aneurysm remains below 5.5 cm. Patients with an aneurysm over 4.5 cm require an ultrasound scan every three months. Once the aneurysm reaches 5.5 cm, patients are referred for consideration of elective surgery.

      Managing Abdominal Aortic Aneurysms: Screening and Treatment Guidelines

      Abdominal aortic aneurysms (AAAs) are a serious health concern that require careful management. This article outlines the screening and treatment guidelines for AAAs.

      Screening for AAAs is done initially by an ultrasound scan of the abdomen. Men are invited for an initial ultrasound during the year of their 65th birthday, while women are not routinely screened. Patients with an AAA less than 3 cm are discharged, while those with an AAA between 3 and 4.4 cm are invited back for yearly screening. Patients with an AAA between 4.5 and 5.4 cm require an ultrasound scan every three months, while those with an AAA over 5.5 cm are referred to a vascular surgeon for consideration of elective surgery.

      Elective surgery is recommended for aneurysms larger than 5.5 cm in diameter or those that are growing rapidly.

    • A 7-week old male infant is presented to the GP clinic by his mother for a regular examination. During auscultation of the baby's heart, you detect a harsh ejection systolic murmur that is most audible at the second intercostal space on the right parasternal area and extends to the neck. Additionally, you observe that the baby has a small upturned nose, a long philtrum, a small chin, and swollen eyes. What is the probable syndrome that this baby is suffering from?

      Your Answer: Prader-Willi syndrome

      Correct Answer: William's syndrome

      Explanation:

      Aortic stenosis is commonly seen in individuals with William’s syndrome, which is characterized by distinct facial features such as a small upturned nose, long philtrum, wide mouth, full lips, small chin, and puffiness around the eyes. On the other hand, Down’s syndrome is typically associated with atrioventricular septal defects, while Klinefelter syndrome is linked to hypogonadism. Angelman syndrome, on the other hand, is not commonly associated with aortic stenosis.

      Aortic Stenosis in Children: Causes and Management

      Aortic stenosis is a type of congenital heart disease that affects 5% of children. It can be associated with other conditions such as William’s syndrome, coarctation of the aorta, and Turner’s syndrome. The aim of management is to delay or avoid valve replacement if possible. However, if the gradient across the valve is greater than 60 mmHg, balloon valvotomy may be necessary. It is important to monitor and manage aortic stenosis in children to prevent complications and ensure optimal health outcomes.

      What is the most appropriate treatment for this patient? Choose ONE answer only.

      Your Answer: Phenoxymethylpenicillin for 10 days

      Explanation:

      Antibiotic Treatment for Tonsillitis Based on Centor Score

      Tonsillitis is a common condition that can be caused by a bacterial or viral infection. Antibiotics are not always necessary for a sore throat, but in cases where the patient has a high probability of a bacterial infection-induced sore throat, antibiotic therapy may be beneficial. The Centor score is a tool used to predict bacterial infection in people with a sore throat. A score of 3 or 4 means that the patient has a high probability of having a bacterial infection-induced sore throat and may benefit from antibiotics.

      The first-line antibiotic therapy for tonsillitis is 10 days of phenoxymethylpenicillin. However, it is important to check the patient’s allergy status before prescribing penicillin. If the patient is allergic to penicillin, 5 days of erythromycin or clarithromycin can be used. Amoxicillin and other broad-spectrum antibiotics should be avoided in the blind treatment of throat infections.

      In cases where the Centor score is 2, a bacterial infection is less likely, and antibiotic therapy is unlikely to be required. In such cases, conservative management such as mouth rinses can be used to alleviate discomfort and swelling.

      It is important to note that antibiotic therapy should only be prescribed when necessary, and a delayed prescription may be considered in some cases. A delayed prescription should only be considered if it is safe not to treat immediately.

      What is the most appropriate first-line treatment for this patient?

      Your Answer: Labetalol

      Explanation:

      Treatment Options for Pre-eclampsia in Pregnancy

      Pre-eclampsia is a serious condition that can occur during pregnancy, characterized by high blood pressure, headaches, flashing lights, and vomiting. The following are treatment options for pre-eclampsia:

      Labetalol: This beta-blocker is the first-line treatment for pre-eclampsia. According to NICE guidelines, patients should be admitted for monitoring if their blood pressure is above 140/90 mmHg. Labetalol should be used if their systolic blood pressure goes above 150 mmHg or diastolic blood pressure above 100 mmHg. Nifedipine can be used as an alternative if labetalol is contraindicated or not tolerated.

      Ramipril: Angiotensin-converting enzyme inhibitors are not recommended during pregnancy due to potential harm to the fetus.

      Hydralazine: This vasodilator is reserved for severe pre-eclampsia and requires specialist support.

      Methyldopa: This medication is the third-line option if labetalol is ineffective and nifedipine is not tolerated or ineffective.

      Nifedipine: This calcium channel blocker is the second-line treatment if labetalol is ineffective or not tolerated.

      In conclusion, pre-eclampsia requires prompt treatment to prevent serious complications. Labetalol is the first-line treatment, and other medications can be used if necessary. It is important to consult with a healthcare provider to determine the best course of action for each individual case.

      Your Answer: Whooping cough

      Correct Answer: HIV

      Explanation:

      Notifying authorities about HIV is not required.

      Notifiable Diseases in the UK

      In the UK, certain diseases are considered notifiable, meaning that the Local Health Protection Team must be notified if a case is suspected or confirmed. The Proper Officer at the team will then inform the Health Protection Agency on a weekly basis. Notifiable diseases include acute encephalitis, acute infectious hepatitis, acute meningitis, acute poliomyelitis, anthrax, botulism, brucellosis, cholera, COVID-19, diphtheria, enteric fever, food poisoning, haemolytic uraemic syndrome, infectious bloody diarrhoea, invasive group A streptococcal disease, legionnaires disease, leprosy, malaria, measles, meningococcal septicaemia, mumps, plague, rabies, rubella, severe acute respiratory syndrome, scarlet fever, smallpox, tetanus, tuberculosis, typhus, viral haemorrhagic fever, whooping cough, and yellow fever.

      It is important to note that HIV is not a notifiable disease in the UK, and in April 2010, dysentery, ophthalmia neonatorum, leptospirosis, and relapsing fever were removed from the list of notifiable diseases. The purpose of notifiable diseases is to monitor and control the spread of infectious diseases in the population. By requiring healthcare professionals to report cases, public health officials can track outbreaks and take appropriate measures to prevent further transmission.

    • A 40-year-old female patient comes to you at the cardiology department complaining of a sharp, stabbing chest pain behind her breastbone. The pain is not spreading to any other part of her body, and she denies feeling sweaty or experiencing nausea and vomiting. She reports that the pain worsens at night when she lies flat in bed and improves slightly when she sits up. She reveals that she has been diagnosed with systemic lupus and is taking regular medication for it. During auscultation, you hear scratchy, rubbing sounds that are most audible during systole. You decide to order an ECG to confirm the diagnosis. What ECG findings are you most likely to observe?

      Your Answer: Saddle-shaped ST elevation

      Explanation:

      The vignette describes classic symptoms of pericarditis, including a sharp central chest pain that is relieved by sitting up and leaning forward, but worsened by lying flat or taking deep breaths. The patient’s past medical history of systemic lupus also increases the likelihood of pericarditis. On auscultation, scratchy, rubbing S1 and S2 sounds can be heard. The most likely ECG finding in this case is saddle shaped ST elevation, which is a hallmark of pericarditis. Other potential causes of ST elevation include STEMI and left bundle branch block, but these can be ruled out based on the symptoms and examination findings. Narrow peaking T waves are often seen in hyperkalaemia, but this is not the most likely ECG finding in this case.

      Understanding Acute Pericarditis

      Acute pericarditis is a medical condition characterized by inflammation of the pericardial sac that lasts for less than 4-6 weeks. The condition can be caused by various factors such as viral infections, tuberculosis, uraemia, post-myocardial infarction, autoimmune pericarditis, radiotherapy, connective tissue disease, hypothyroidism, malignancy, and trauma. Symptoms of acute pericarditis include chest pain, non-productive cough, dyspnoea, and flu-like symptoms. Patients may also experience pericardial rub.

      To diagnose acute pericarditis, doctors may perform an electrocardiogram (ECG) to check for changes in the heart’s electrical activity. Blood tests may also be conducted to check for inflammatory markers and troponin levels. Patients suspected of having acute pericarditis should undergo transthoracic echocardiography.

      Treatment for acute pericarditis depends on the underlying cause. Patients with high-risk features such as fever or elevated troponin levels may need to be hospitalized. However, most patients with pericarditis secondary to viral infection can be managed as outpatients. Strenuous physical activity should be avoided until symptoms resolve and inflammatory markers normalize. A combination of nonsteroidal anti-inflammatory drugs (NSAIDs) and colchicine is typically used as first-line treatment for patients with acute idiopathic or viral pericarditis. The medication is usually tapered off over 1-2 weeks.

      Overall, understanding acute pericarditis is important for prompt diagnosis and appropriate management of the condition.

      Which of the following primary tumours most commonly metastasises to bone?

      Your Answer: Renal carcinoma

      Correct Answer: Bronchial carcinoma

      Explanation:

      Metastasis Patterns of Common Carcinomas

      Carcinomas are malignant tumors that can spread to other parts of the body through a process called metastasis. The patterns of metastasis vary depending on the type of carcinoma. Here are some common carcinomas and their typical metastasis patterns:

      Bronchial Carcinoma: This type of carcinoma often spreads to the bone or brain. Symptoms may include difficulty breathing, coughing, chest pain, weight loss, and fatigue.

      Brain Carcinoma: Primary malignant brain tumors rarely spread to other parts of the body, but they can spread to surrounding areas of the brain and spinal cord.

      Renal Carcinoma: Renal cancers commonly metastasize to the lungs, producing lesions that appear like cannonballs on a chest X-ray. They can also spread to the bone, causing osteolytic lesions.

      Gastric Carcinoma: Gastric cancers tend to spread to the liver, lung, and peritoneum. Tumors that have a preference for bone metastasis include those of the lung, prostate, breast, kidney, and thyroid.

      Colorectal Carcinoma: Colorectal cancers commonly metastasize to the liver, lung, and peritoneum. Tumors that have a preference for bone metastasis include those of the lung, prostate, breast, kidney, and thyroid.

      Understanding the patterns of metastasis for different types of carcinomas can help with early detection and treatment. If you experience any symptoms or have concerns, it’s important to speak with your healthcare provider.

      What is the most probable diagnosis?

      Your Answer: Olecranon bursitis

      Explanation:

      The patient’s symptoms suggest olecranon bursitis, which is inflammation of the bursa over the olecranon process. This can be caused by trauma or may be idiopathic. The patient reports a posterior swelling at the elbow, which is tender and fluctuant. Management includes NSAIDs, RICE, and a compression bandage. If septic bursitis is suspected, antibiotics may be necessary. Golfer’s elbow, gout, and septic joint are less likely diagnoses. Tennis elbow, which is more common than golfer’s elbow, is characterized by pain in the lateral elbow and tenderness over the lateral epicondyle, but is not associated with a posterior swelling.

      Your Answer: Sodium valproate

      Correct Answer: Phenytoin

      Explanation:

      Phenytoin is recognized to cause peripheral neuropathy as a side effect.

      Phenytoin: Mechanism of Action and Adverse Effects

      Phenytoin is a medication used to manage seizures. Its mechanism of action involves binding to sodium channels, which increases their refractory period. However, the drug is associated with a large number of adverse effects, which can be categorized as acute, chronic, idiosyncratic, and teratogenic. Acute effects include dizziness, diplopia, nystagmus, slurred speech, ataxia, confusion, and seizures. Chronic effects include gingival hyperplasia, hirsutism, coarsening of facial features, drowsiness, megaloblastic anemia, peripheral neuropathy, enhanced vitamin D metabolism causing osteomalacia, lymphadenopathy, and dyskinesia. Idiosyncratic effects include fever, rashes, hepatitis, Dupuytren’s contracture, aplastic anemia, and drug-induced lupus. Teratogenic effects are associated with cleft palate and congenital heart disease. Although routine monitoring of phenytoin levels is not necessary, trough levels should be checked before dosing in cases of dose adjustment, suspected toxicity, or non-adherence to the prescribed medication.

    • A 28-year-old man presents to the emergency department with complaints of severe pain in his perineum and scrotum. He has type 2 diabetes that is currently well managed with dapagliflozin. Upon examination, a purple rash with bullae is observed covering the entire perineum and extending up the scrotum. The patient reports intense pain, but reduced sensation is noted upon palpation of the rash. Vital signs are as follows: BP 110/90 mmHg, heart rate 109bpm, respiration rate 21/minute, temperature 38.1ºC, and oxygen saturation 98% on room air. What is the likely diagnosis?

      Your Answer: Necrotizing fasciitis

      Explanation:

      The patient’s symptoms are consistent with necrotizing fasciitis, which often affects the perineum. The patient is experiencing severe pain, which may be causing his fever and rapid heart and breathing rates. As a type 2 diabetic taking dapagliflozin, an SGLT-2 inhibitor, his risk of developing necrotizing fasciitis is increased. While cellulitis can have similar symptoms in the early stages, the presence of bullae, purple discoloration, and severe pain in a patient with risk factors for necrotizing fasciitis make it less likely. Septic arthritis is not a likely diagnosis as it affects joint spaces, which is not the case in this patient. Pyoderma gangrenosum, which is associated with inflammatory conditions, is not a likely diagnosis as the rash is not ulcerated and the patient has no history of inflammatory bowel disease or rheumatoid arthritis.

      Understanding Necrotising Fasciitis

      Necrotising fasciitis is a serious medical emergency that can be difficult to identify in its early stages. It can be classified into two types based on the causative organism. Type 1 is the most common and is caused by mixed anaerobes and aerobes, often occurring post-surgery in diabetics. Type 2 is caused by Streptococcus pyogenes. There are several risk factors associated with necrotising fasciitis, including recent trauma, burns, or soft tissue infections, diabetes mellitus, intravenous drug use, and immunosuppression. The most commonly affected site is the perineum, also known as Fournier’s gangrene.

      The features of necrotising fasciitis include an acute onset, pain, swelling, and erythema at the affected site. It often presents as rapidly worsening cellulitis with pain that is out of keeping with physical features. The infected tissue is extremely tender and may have hypoaesthesia to light touch. Late signs include skin necrosis and crepitus/gas gangrene. Fever and tachycardia may be absent or occur late in the presentation.

      Management of necrotising fasciitis requires urgent surgical referral for debridement and intravenous antibiotics. The prognosis for this condition is poor, with an average mortality rate of 20%. It is important to be aware of the risk factors and features of necrotising fasciitis to ensure prompt diagnosis and treatment.

      Correct Answer: Apixaban

      Explanation:

      For cancer patients with VTE, the recommended treatment is a DOAC for a period of 6 months. Among the DOACs, apixaban is the most suitable option as it has been found to have a lower risk of bleeding complications compared to LMWH and VKA. Moreover, patients taking apixaban can benefit from oral treatment and avoid frequent monitoring required with other anticoagulation treatments. Studies have also shown that apixaban is the most cost-effective option as it results in fewer bleeds.

      NICE updated their guidelines on the investigation and management of venous thromboembolism (VTE) in 2020. The use of direct oral anticoagulants (DOACs) is recommended as first-line treatment for most people with VTE, including as interim anticoagulants before a definite diagnosis is made. Routine cancer screening is no longer recommended following a VTE diagnosis. The cornerstone of VTE management is anticoagulant therapy, with DOACs being the preferred choice. All patients should have anticoagulation for at least 3 months, with the length of anticoagulation being determined by whether the VTE was provoked or unprovoked.

    Correct

    • A 28-year-old woman delivers a baby girl at 39 weeks gestation using ventouse delivery. She expresses concern to one of the doctors about a lump on her baby's forehead. Upon examination, the neonate has a soft, puffy swelling that crosses suture lines on the vertex. What is the most likely diagnosis, and what advice should be given to the mother?

      Your Answer: Resolves within a few days

      Explanation:

      Caput succedaneum is a swollen area that typically appears over the presenting part and extends across suture lines. In this case, the diagnosis is caput succedaneum, which occurred after a traumatic delivery (ventouse). The mother should be informed that no intervention is necessary as the swelling will subside within a few days. It would be inappropriate to advise the mother that immediate medical or surgical intervention is required. Unlike cephalohaematoma, which takes months to resolve and does not cross suture lines, caput succedaneum resolves within a few days. Therefore, advising the mother that it will take a few months or years to resolve would be inaccurate.

      Understanding Caput Succedaneum

      Caput succedaneum is a condition that refers to the swelling of the scalp at the top of the head, usually at the vertex. This swelling is caused by the mechanical trauma that occurs during delivery, particularly in prolonged deliveries or those that involve the use of vacuum delivery. The condition is characterized by soft, puffy swelling due to localized edema that crosses suture lines.

      Compared to cephalohaematoma, which is a collection of blood under the scalp, caput succedaneum is caused by edema. While cephalohaematoma is limited to a specific area and does not cross suture lines, caput succedaneum can affect a larger area and cross suture lines. Fortunately, no treatment is needed for caput succedaneum, as the swelling usually resolves on its own within a few days.
