As a side-effect, which antidepressants cause the cheese effect (a hypertensive reaction)?
Your Answer: Monoamine oxidase inhibitors (MAOIs)
Explanation:Differential Diagnosis: Jaundice and Abdominal Symptoms
Gilbert Syndrome:
Gilbert syndrome is an inherited condition that can manifest as jaundice on clinical examination. Patients may also experience non-specific symptoms such as abdominal cramps, fatigue, and malaise. Fasting, febrile illness, alcohol, or exercise can exacerbate jaundice in patients with Gilbert syndrome. Diagnosis is based on a thorough history and physical examination, as well as blood tests that show unconjugated hyperbilirubinaemia.Haemolytic Anaemia:
Haemolysis is the premature destruction of erythrocytes, which can lead to anaemia if bone marrow activity cannot compensate for erythrocyte loss. Mild haemolysis can be asymptomatic, while severe haemolysis can cause life-threatening symptoms such as angina and cardiopulmonary decompensation. Changes in lactate dehydrogenase and serum haptoglobin levels are the most sensitive general tests for haemolytic anaemia.Hepatitis A:
Hepatitis A is a viral infection that results almost exclusively from ingestion, typically through faecal-oral transmission. Symptoms include fatigue, anorexia, nausea, and vomiting. LFT abnormalities are common, and diagnosis is based on serologic testing for immunoglobulin M (IgM) antibody to HAV.Hepatitis B:
Hepatitis B is a viral infection that is transmitted haematogenously and sexually. Symptoms include fatigue, anorexia, nausea, and vomiting. LFT abnormalities are common, and diagnosis is based on serologic testing for hepatitis B surface antigen (HBsAg).Cholecystitis:
Cholecystitis is inflammation of the gall bladder that occurs most commonly because of an obstruction of the cystic duct by gallstones arising from the gall bladder. Symptoms include upper abdominal pain, nausea, vomiting, and fever. Signs of peritoneal irritation may also be present.Conclusion:
In summary, the differential diagnosis of jaundice and abdominal symptoms includes Gilbert syndrome, haemolytic anaemia, hepatitis A, hepatitis B, and cholecystitis. Diagnosis is based on a thorough history and physical examination, as well as blood tests and serologic testing as appropriate. Treatment -

As a junior doctor in the Emergency Department, you encounter a 40-year-old woman who has been brought in by the police under a section 135. The police had to obtain a warrant as part of the process. The patient is currently agitated and speaking incoherently about religious phrases. She has a documented history of severe depression.
What powers does section 135 grant to the police in this situation?Your Answer: To bring a person with suspected mental health issues in from the community
Correct Answer: To bring a person with suspected mental health issues in from their property
Explanation:If the police believe that someone requires a mental health assessment or treatment, they can request a section 135 to remove the individual from their property. The procedure involves an Approved Mental Health Practitioner (AMHP) presenting evidence at a Magistrate’s Court to obtain a warrant. This warrant permits the Police, an AMHP, and a registered medical practitioner to enter the premises and conduct an assessment or take the person to a safe location for evaluation.
Sectioning under the Mental Health Act is a legal process used for individuals who refuse voluntary admission. This process excludes patients who are under the influence of drugs or alcohol. There are several sections under the Mental Health Act that allow for different types of admission and treatment.
Section 2 allows for admission for assessment for up to 28 days, which is not renewable. An Approved Mental Health Professional (AMHP) or the nearest relative (NR) can make the application on the recommendation of two doctors, one of whom should be an approved consultant psychiatrist. Treatment can be given against the patient’s wishes.
Section 3 allows for admission for treatment for up to 6 months, which can be renewed. An AMHP and two doctors, both of whom must have seen the patient within the past 24 hours, can make the application. Treatment can also be given against the patient’s wishes.
Section 4 is used as an emergency 72-hour assessment order when a section 2 would involve an unacceptable delay. A GP and an AMHP or NR can make the application, which is often changed to a section 2 upon arrival at the hospital.
Section 5(2) allows a doctor to legally detain a voluntary patient in hospital for 72 hours, while section 5(4) allows a nurse to detain a voluntary patient for 6 hours.
Section 17a allows for Supervised Community Treatment (Community Treatment Order) and can be used to recall a patient to the hospital for treatment if they do not comply with the conditions of the order in the community, such as taking medication.
Section 135 allows for a court order to be obtained to allow the police to break into a property to remove a person to a Place of Safety. Section 136 allows for someone found in a public place who appears to have a mental disorder to be taken by the police to a Place of Safety. This section can only be used for up to 24 hours while a Mental Health Act assessment is arranged.

A 28-year-old woman comes to the Endocrine Clinic with a history of hyperthyroidism. Her blood tests confirm that she is currently experiencing thyrotoxicosis. She is hoping to conceive and wants to discuss her treatment options.
What is the most suitable treatment for her condition in this scenario?Your Answer: Propylthiouracil and thyroxine
Correct Answer: Thyroidectomy
Explanation:Treatment Options for Hyperthyroidism in Women Planning a Pregnancy
When it comes to treating hyperthyroidism in women who are planning a pregnancy, there are several options to consider. Definitive treatment, such as thyroidectomy, is the preferred option as it eliminates the risk of thyrotoxicosis during pregnancy and the need for medication that could harm the fetus. However, following thyroidectomy, the patient will need thyroxine replacement and should wait until she is euthyroid before trying to conceive.
Propylthiouracil and thyroxine are not recommended for use during pregnancy due to the risk of fetal goitre or hypothyroidism. Carbimazole is teratogenic and should not be started in women planning a pregnancy. Propylthiouracil can be used in low doses if there is no other suitable alternative.
Radioactive iodine is highly effective but is contraindicated in women planning a pregnancy within six months. This option can be considered if the patient is willing to continue contraception until six months after treatment. Ultimately, the best course of action will depend on the individual patient’s needs and preferences, and should be discussed with a healthcare provider.

An 83-year-old woman with a history of hypertension and atrial fibrillation arrives at the emergency department with dysarthria and left-sided weakness that she noticed earlier today. During the examination, left-sided hemiparesis is observed, and her blood glucose level is 6.5 mmol/L. What is the next appropriate investigation?
Your Answer: Non-contrast CT head
Explanation:Assessment and Investigations for Stroke
Whilst diagnosing a stroke may be straightforward in some cases, it can be challenging when symptoms are vague. The FAST screening tool, which stands for Face/Arms/Speech/Time, is a well-known tool used by the general public to identify stroke symptoms. However, medical professionals use a validated tool called the ROSIER score, recommended by the Royal College of Physicians. The ROSIER score assesses for loss of consciousness or syncope, seizure activity, and new, acute onset of asymmetric facial, arm, or leg weakness, speech disturbance, or visual field defect. A score of greater than zero indicates a likely stroke.
When investigating suspected stroke, a non-contrast CT head scan is the first line radiological investigation. The key question to answer is whether the stroke is ischaemic or haemorrhagic, as this determines the appropriate management. Ischaemic strokes may show areas of low density in the grey and white matter of the territory, while haemorrhagic strokes typically show areas of hyperdense material surrounded by low density. It is important to identify the type of stroke promptly, as thrombolysis and thrombectomy play an increasing role in acute stroke management. In rare cases, a third pathology such as a tumour may also be detected.

A 32-year-old female with a history of alcoholic liver disease presents with frank haematemesis. She had been discharged just two months ago after receiving treatment for bleeding oesophageal varices. What is the most suitable course of action to take while waiting for endoscopy after resuscitation?
Your Answer: Terlipressin
Explanation:Variceal haemorrhage is a serious condition that requires prompt management. The initial treatment involves resuscitation of the patient before endoscopy. Correcting clotting with FFP and vitamin K is important, as is the use of vasoactive agents such as terlipressin or octreotide. Prophylactic IV antibiotics are also recommended to reduce mortality in patients with liver cirrhosis. Endoscopic variceal band ligation is the preferred method of treatment, and the use of a Sengstaken-Blakemore tube or Transjugular Intrahepatic Portosystemic Shunt (TIPSS) may be necessary if bleeding cannot be controlled. Propranolol and EVL are effective in preventing rebleeding and mortality, and are recommended by NICE guidelines. Proton pump inhibitor cover is given to prevent EVL-induced ulceration.

A 68-year-old man came to your GP clinic complaining of stiffness and pain in his knee joints, painful urination, and a red eye with circumcorneal redness, hypopyon, and photophobia. What is the most probable reason for his red eye?
Your Answer: Scleritis
Correct Answer: Iritis
Explanation:When dealing with reactive arthritis, it is important to keep in mind that anterior uveitis may also be present in addition to conjunctivitis.
Since reactive arthritis is linked to HLA-B27, it is important to consider the possibility of iritis or anterior uveitis, even though conjunctivitis is more commonly seen as part of the triad of symptoms. The specific description of a red eye with circumcorneal redness and hypopyon suggests iritis rather than conjunctivitis. Conjunctivitis typically causes a more generalized redness of the eye and hypopyon is not commonly observed. Corneal ulceration is unlikely in this case as there is no mention of increased fluorescein uptake on the cornea or a visible ulcer. Scleritis can be ruled out as it does not present with circumcorneal redness or hypopyon. While scleritis is associated with systemic conditions such as rheumatoid arthritis and other collagen/vascular disorders like Wegener’s granulomatosis, polyarteritis nodosa, and systemic lupus erythematosus, it is not associated with reactive arthritis. Blepharitis is also an incorrect diagnosis as there were no eyelid symptoms and blepharitis does not typically cause a red eye with photophobic symptoms.
Anterior uveitis, also known as iritis, is a type of inflammation that affects the iris and ciliary body in the front part of the uvea. It is a common cause of red eye and is associated with HLA-B27, which may also be linked to other conditions. Symptoms of anterior uveitis include sudden onset of eye discomfort and pain, small or irregular pupils, intense sensitivity to light, blurred vision, redness, tearing, and the presence of pus and inflammatory cells in the front part of the eye. This condition may be associated with ankylosing spondylitis, reactive arthritis, ulcerative colitis, Crohn’s disease, Behcet’s disease, and sarcoidosis. Urgent review by an ophthalmologist is necessary, and treatment may involve the use of cycloplegics and steroid eye drops.

A 35 year old woman who is 30 weeks pregnant presents with malaise, headaches and vomiting. She is admitted to the obstetrics ward after a routine blood pressure measurement was 190/95 mmHg. Examination reveals right upper quadrant abdominal pain and brisk tendon reflexes. The following blood tests are shown:
Hb 85 g/l
WBC 6 * 109/l
Platelets 89 * 109/l
Bilirubin 2.8 µmol/l
ALP 215 u/l
ALT 260 u/l
γGT 72 u/l
LDH 846 u/I
A peripheral blood film is also taken which shows polychromasia and schistocytes. What is the most likely diagnosis?Your Answer: HELLP syndrome
Explanation:The symptoms of HELLP syndrome, a severe form of pre-eclampsia, include haemolysis (H), elevated liver enzymes (EL), and low platelets (LP). A patient with this condition may experience malaise, nausea, vomiting, and headache, as well as hypertension with proteinuria and epigastric and/or upper abdominal pain. The patient in this case meets the requirements for a diagnosis of HELLP syndrome.
Liver Complications During Pregnancy
During pregnancy, there are several liver complications that may arise. One of the most common is intrahepatic cholestasis of pregnancy, which occurs in about 1% of pregnancies and is typically seen in the third trimester. Symptoms include intense itching, especially in the palms and soles, as well as elevated bilirubin levels. Treatment involves the use of ursodeoxycholic acid for relief and weekly liver function tests. Women with this condition are usually induced at 37 weeks to prevent stillbirth, although maternal morbidity is not typically increased.
Another rare complication is acute fatty liver of pregnancy, which may occur in the third trimester or immediately after delivery. Symptoms include abdominal pain, nausea and vomiting, headache, jaundice, and hypoglycemia. Severe cases may result in pre-eclampsia. ALT levels are typically elevated, and support care is the primary management until delivery can be performed once the patient is stabilized.
Finally, conditions such as Gilbert’s and Dubin-Johnson syndrome may be exacerbated during pregnancy. Additionally, HELLP syndrome, which stands for haemolysis, elevated liver enzymes, and low platelets, is a serious complication that can occur in the third trimester and requires immediate medical attention. Overall, it is important for pregnant women to be aware of these potential liver complications and to seek medical attention if any symptoms arise.

A 56-year-old man presents to the Emergency Department with nausea and vomiting, with associated lethargy. He has mild asthma which is well controlled with a steroid inhaler but has no other medical history of note. He does not smoke but drinks up to 30 units of alcohol a week, mostly on the weekends.
Observations are as follows: Temperature is 37.2 oC, blood pressure is 108/68 mmHg, heart rate is 92 bpm and regular.
On examination, the patient appears to be clinically dehydrated, but there are no other abnormalities noted.
Investigations reveal the following:
Investigation Result Normal Values
Haemoglobin (Hb) 145 g/l 135–175 g/l
White cell count (WCC) 8.2 × 109/l 4.0–11.0 × 109/l
Urea 9.2 mmol/l 2.5–6.5 mmol/l

Which of the following is most suggestive of acute kidney injury rather than chronic renal failure?Your Answer: Oliguria
Explanation:Understanding the Signs and Symptoms of Acute and Chronic Renal Failure
Renal failure can be difficult to diagnose, especially when there are no previous urea and electrolyte levels available for comparison. However, there are certain signs and symptoms that can indicate whether the condition is acute or chronic.
Acute renal failure may present with acute lethargy/fatigue, dehydration, shortness of breath, nausea and vomiting, oliguria, acute onset peripheral edema/edema of the face, confusion, seizures, and coma. On the other hand, chronic renal failure may manifest as anemia, pruritus, long-standing fatigue, weight loss, reduced appetite, and a history of underlying medical conditions such as diabetes or hypertension.
Oliguria, or reduced urine output, is a hallmark of renal failure and can be an early sign of acute renal injury. Nocturia, or increased urination at night, is often found in patients with chronic kidney disease. Peripheral neuropathy is likely to be present in patients with chronic renal failure due to an underlying history of diabetes. Raised parathyroid hormone levels are more commonly found in chronic renal failure, secondary to low calcium levels associated with the condition. Small kidneys are also seen in chronic renal failure, as long-standing conditions affecting the kidney can cause atrophy and reduce function, leading to progressive renal failure. The kidneys are more likely to be of normal size in acute injury.
In summary, understanding the signs and symptoms of acute and chronic renal failure can aid in the diagnosis and management of this condition.

A 26-year-old man complains of rectal bleeding and a sharp, stinging pain during bowel movements. He has been experiencing these symptoms for the past two weeks. The patient reports a history of constipation and notes fresh blood on the toilet paper when wiping. Although rectal examination is challenging due to pain, no external abnormalities are observed. What is the probable diagnosis?
Your Answer: Anal fissure
Explanation:Anal fissures are typically identified by the presence of both pain and bleeding. While thrombosed external hemorrhoids can also cause pain, internal hemorrhoids usually do not. It can be challenging to detect superficial anal fissures during an examination.
Understanding Anal Fissures: Causes, Symptoms, and Treatment
Anal fissures are tears in the lining of the distal anal canal that can be either acute or chronic. Acute fissures last for less than six weeks, while chronic fissures persist for more than six weeks. The most common risk factors for anal fissures include constipation, inflammatory bowel disease, and sexually transmitted infections such as HIV, syphilis, and herpes.
Symptoms of anal fissures include painful, bright red rectal bleeding, with around 90% of fissures occurring on the posterior midline. If fissures are found in other locations, underlying causes such as Crohn’s disease should be considered.
Management of acute anal fissures involves softening stool, dietary advice, bulk-forming laxatives, lubricants, topical anaesthetics, and analgesia. For chronic anal fissures, the same techniques should be continued, and topical glyceryl trinitrate (GTN) is the first-line treatment. If GTN is not effective after eight weeks, surgery (sphincterotomy) or botulinum toxin may be considered, and referral to secondary care is recommended.
In summary, anal fissures can be a painful and uncomfortable condition, but with proper management, they can be effectively treated. It is important to identify and address underlying risk factors to prevent the development of chronic fissures.

A 55-year-old female patient arrived at the emergency department complaining of intense pain in her left eye, along with redness and sensitivity to light. Upon examination, her intraocular pressure was found to be elevated at 30 mmHg, and her pupil was mid-dilated. After diagnosing her with acute angle closure glaucoma, you promptly administered IV acetazolamide and topical pilocarpine. What is the definitive treatment for this condition?
Your Answer: Laser peripheral iridotomy in both eyes
Explanation:The definitive treatment for acute angle-closure glaucoma is laser peripheral iridotomy, which creates an additional pathway in the iris for aqueous to flow from the posterior chamber to the anterior chamber and be drained into the angle. While topical beta blockers, alpha agonists, prostaglandin analogues, and carbonic anhydrase inhibitors can all help control intraocular pressure in glaucoma patients, they are not considered definitive treatments for AACG.
Glaucoma is a group of disorders that cause optic neuropathy due to increased intraocular pressure (IOP). However, not all patients with raised IOP have glaucoma, and vice versa. Acute angle-closure glaucoma (AACG) is a type of glaucoma where there is a rise in IOP due to impaired aqueous outflow. Factors that increase the risk of AACG include hypermetropia, pupillary dilatation, and lens growth associated with age. Symptoms of AACG include severe pain, decreased visual acuity, haloes around lights, and a hard, red-eye. Management of AACG is an emergency and requires urgent referral to an ophthalmologist. Emergency medical treatment is necessary to lower the IOP, followed by definitive surgical treatment once the acute attack has subsided.
There are no specific guidelines for the initial medical treatment of AACG, but a combination of eye drops may be used, including a direct parasympathomimetic, a beta-blocker, and an alpha-2 agonist. Intravenous acetazolamide may also be administered to reduce aqueous secretions. Definitive management of AACG involves laser peripheral iridotomy, which creates a small hole in the peripheral iris to allow aqueous humour to flow to the angle. It is important to seek medical attention immediately if symptoms of AACG are present to prevent permanent vision loss.

While on your GP placement, you hear a cry for help coming from the reception area. Rushing over, you see a young girl who appears to be around 4 years old collapsed on the floor. Upon checking, you find that there are no signs of life.
What would be your initial course of action in this situation?Your Answer: 5 rescue breaths
Explanation:According to the latest Resuscitation Council guidelines for paediatric BLS, the correct initial action when there are no signs of breathing is to give 5 rescue breaths. This is different from the adult algorithm where chest compressions may be done first. Giving 2 rescue breaths initially is incorrect. Chest compressions are given at a ratio of 30:2 if there is only one rescuer and at a ratio of 15:2 if there are multiple rescuers, but only after the initial 5 rescue breaths have been given. It is important to remember that in children, respiratory arrest is more common than cardiac arrest.
Paediatric Basic Life Support Guidelines
Paediatric basic life support guidelines were updated in 2015 by the Resuscitation Council. Lay rescuers should use a compression:ventilation ratio of 30:2 for children under 1 year and between 1 year and puberty, a child is defined. If there are two or more rescuers, a ratio of 15:2 should be used.
The algorithm for paediatric basic life support starts with checking if the child is unresponsive and shouting for help. The airway should be opened, and breathing should be checked by looking, listening, and feeling for breaths. If the child is not breathing, five rescue breaths should be given, and signs of circulation should be checked.
For infants, the brachial or femoral pulse should be used, while children should use the femoral pulse. Chest compressions should be performed at a ratio of 15:2, with a rate of 100-120 compressions per minute for both infants and children. The depth of compressions should be at least one-third of the anterior-posterior dimension of the chest, which is approximately 4 cm for an infant and 5 cm for a child.
In children, the lower half of the sternum should be compressed, while in infants, a two-thumb encircling technique should be used for chest compressions. These guidelines are crucial for anyone who may need to perform basic life support on a child, and it is essential to follow them carefully to ensure the best possible outcome.

A 25-year-old farm worker is admitted to hospital with a 5-day history of headache, fever, severe myalgia and a petechial rash. He is jaundiced, febrile, has tachycardia and has not passed urine for over 14 hours. His urea level is raised and liver function tests indicate hepatocellular damage.
Which of the following is the most likely diagnosis?
Your Answer: Brucellosis
Correct Answer: Weil’s disease
Explanation:Comparing Zoonotic Infections: Symptoms and Characteristics
Weil’s Disease, Brucellosis, Lyme Disease, Orf, and Rat-bite Fever are all zoonotic infections that can be transmitted from animals to humans. However, each infection has its own unique symptoms and characteristics.
Weil’s Disease is a severe form of leptospirosis caused by Leptospira icterohaemorrhagiae. It is transmitted via direct or indirect contact with animals, especially rodents. Symptoms include flu-like symptoms, severe headache, petechial or purpuric rashes, epistaxis, jaundice, renal failure, meningism, and multiorgan failure.
Brucellosis is caused by the bacterial genus Brucella and is transmitted from animals to humans by ingestion of infected food products, direct contact with an infected animal, or inhalation of aerosols. Symptoms include fever, myalgia, weight loss, coughing, vomiting, lymphadenopathy, and splenomegaly. Males may develop epididymo-orchitis.
Lyme Disease is caused by Borrelia burgdorferi and is transmitted to humans via tick bites from infected ticks. Symptoms include isolated erythema migrans, the characteristic skin rash which has the appearance of a ‘bull’s eye’ and a febrile illness. Untreated patients may go on to develop cardiac, neurological or rheumatological symptoms months after the initial bite.
Orf is a zoonotic mucocutaneous lesion caused by a pox virus and is most commonly seen in workers who handle sheep. Symptoms include firm red papules that develop, enlarge, and become painful before spontaneously resolving. Systemic illness is rare with orf.
Rat-bite Fever is an acute, febrile illness caused by bacteria transmitted by rodents. Symptoms include fever, a rash, and polyarthritis. The rash is usually widespread and may be maculopapular, petechial, or purpuric.
In summary, each zoonotic infection has its own unique symptoms and characteristics, making it important to accurately diagnose and treat each infection accordingly.

A 67-year-old male presents to an urgent care centre with concerns about decreased frequency of urination. He reports only urinating once in the past 12 hours and feels unable to urinate despite the urge to do so. The patient has a medical history of diabetes mellitus managed with metformin and chronic back pain managed with ibuprofen and PPI cover. He has no known allergies. Blood tests reveal the following results: Na+ 139 mmol/L (135 - 145), K+ 4.8 mmol/L (3.5 - 5.0), Bicarbonate 22 mmol/L (22 - 29), Urea 7.1 mmol/L (2.0 - 7.0), and Creatinine 200 µmol/L (55 - 120). The patient's previous creatinine level was 119 µmol/L. The general practitioner refers the patient to the emergency department for further investigation. What is the correct classification?
Your Answer: Acute Kidney Injury stage 1
Explanation:The patient in this vignette meets the criteria for AKI Stage 1, which is characterized by a moderate increase in serum creatinine (1.5-1.9 times the baseline) or reduced urine output (<0.5 mL/kg/hr) for at least 6 hours. The patient has risk factors such as age, diabetes mellitus, and NSAID use for back pain, which can contribute to AKI. It is important to note that AKI is a classification and not a diagnosis. AKI Stage 2 is characterized by a more significant increase in serum creatinine (2-2.9 times the baseline) or reduced urine output for at least 12 hours. The vignette does not show renal function that is severe enough to meet this classification. AKI Stage 3 is the most severe stage, with a serum creatinine increase of 3 times or more from baseline or reduced urine output for at least 24 hours. Again, the patient’s renal function is not severe enough to meet this classification. There is no AKI Stage 4 or 5. Chronic kidney disease is classified from stages 1-5 based on the patient’s estimated glomerular filtration rate (eGFR). A patient with CKD Stage 4 would have an eGFR of 15-29 ml/min/1.73m², while a patient with CKD Stage 5 would have end-stage renal disease with an eGFR <15 ml/min/1.73m² or be receiving renal replacement therapy. The NICE guidelines for acute kidney injury (AKI) identify risk factors such as emergency surgery, CKD, diabetes, and use of nephrotoxic drugs. Diagnostic criteria include a rise in creatinine, fall in urine output, or fall in eGFR. The KDIGO criteria are used to stage AKI, with stage 3 indicating the most severe cases. Referral to a nephrologist is recommended for certain cases, such as AKI with no known cause or inadequate response to treatment. Complications of AKI include CKD, hyperkalaemia, metabolic acidosis, and fluid overload.

A 16-year-old boy with Marfan syndrome is seen in the Cardiology Clinic. He has been researching possible complications of his condition online and is worried about potential cardiac issues.
Which of the following cardiac abnormalities is most probable in this patient?Your Answer: Dilated cardiomyopathy
Correct Answer: Aortic regurgitation
Explanation:Cardiac Abnormalities Associated with Marfan Syndrome
Marfan syndrome is commonly associated with cardiac abnormalities, with aortic root dilatation being the most prevalent, found in approximately 80% of cases. This can lead to aortic regurgitation and even dissection. While there is some evidence of a slight increase in atrial septal defects in Marfan syndrome patients, it is not as common as aortic regurgitation or mitral valve prolapse. Dilated cardiomyopathy can also present in Marfan syndrome patients, although it is not as prevalent as aortic root dilatation or regurgitation. Pulmonary regurgitation is also increased in incidence in Marfan syndrome, but it is still less common than aortic regurgitation. Finally, while persistent ductus arteriosus is more commonly found in Marfan syndrome patients than in the general population, the association is relatively weak. Overall, Marfan syndrome patients should be monitored closely for these cardiac abnormalities to ensure proper management and treatment.

A 50-year-old woman is prescribed mirtazapine 15mg ON for the treatment of moderate depression, based on her previous positive response to this medication. She has no significant medical history. However, after 4 weeks of taking mirtazapine, she reports experiencing sedation as a side effect and has not achieved the desired therapeutic response. What is the best course of action to manage this situation?
Your Answer: Increase the dose of mirtazapine to 30mg ON
Explanation:Mirtazapine is more likely to cause sedation at lower doses (e.g. 15mg) than at higher doses (e.g. 45mg).
The appropriate course of action is to increase the mirtazapine dose to 30mg at night. If there has been no improvement in symptoms after four weeks, it is reasonable to increase the dose to the usual minimum effective dose. It is important to note that sedation typically decreases with higher doses of mirtazapine due to increased noradrenergic activity.
If the patient does not respond to or cannot tolerate an increase in mirtazapine, switching to an alternative medication such as fluoxetine or venlafaxine may be considered. However, it is advisable to try the usual minimum effective dose of mirtazapine before deciding to switch medications.
Amitriptyline and other TCAs are no longer commonly used in the treatment of depression due to the risk of overdose.
In cases of severe depression, depression that does not respond to primary care management, or suspected bipolar disorder, it is recommended to seek a secondary care opinion.
Mirtazapine: An Effective Antidepressant with Fewer Side Effects
Mirtazapine is an antidepressant medication that functions by blocking alpha2-adrenergic receptors, which leads to an increase in the release of neurotransmitters. Compared to other antidepressants, mirtazapine has fewer side effects and interactions, making it a suitable option for older individuals who may be more susceptible to adverse effects or are taking other medications.
Mirtazapine has two side effects that can be beneficial for older individuals who are experiencing insomnia and poor appetite. These side effects include sedation and an increased appetite. As a result, mirtazapine is typically taken in the evening to help with sleep and to stimulate appetite.
Overall, mirtazapine is an effective antidepressant that is well-tolerated by many individuals. Its unique side effects make it a valuable option for older individuals who may have difficulty sleeping or eating.

A 5-year-old girl presents with a sore throat that has been bothering her for 3 days. She has no cough or runny nose. Her mother has kept her home from preschool. Upon examination, she has a fever and swollen tonsils with white patches. She also has tender lymph nodes in her neck.
What is the most appropriate treatment for this patient? Choose ONE answer only.Your Answer: Phenoxymethylpenicillin for 7 days
Correct 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.

A 35-year-old female patient visits her general practitioner with a concern of experiencing bleeding following sexual intercourse. What is the most frequently identifiable reason for postcoital bleeding?
Your Answer: Cervical ectropion
Explanation:Postcoital bleeding is most commonly caused by cervical ectropion.
Understanding Postcoital Bleeding
Postcoital bleeding refers to vaginal bleeding that occurs after sexual intercourse. In approximately 50% of cases, no identifiable pathology is found. However, cervical ectropion is the most common identifiable cause, accounting for around 33% of cases. This condition is more prevalent in women who are taking the combined oral contraceptive pill. Other potential causes of postcoital bleeding include cervicitis, which may be due to Chlamydia infection, cervical cancer, polyps, and trauma.

A 28-year-old female patient visits your clinic with a complaint of fishy-smelling vaginal discharge. You suspect bacterial vaginosis and decide to prescribe metronidazole. The patient has no known drug allergies and is generally healthy, except for taking the combined oral contraceptive pill (COCP). What is the most crucial advice you should provide her regarding the potential side effects of metronidazole?
Your Answer: She should abstain from alcohol whilst taking metronidazole
Explanation:Taking metronidazole and alcohol together can result in a disulfiram-like reaction, so patients should be cautioned against consuming alcohol while on the medication. Metronidazole is not associated with cholestasis, hepatotoxicity, or QT prolongation. As an enzyme inhibitor, metronidazole enhances the efficacy of the COCP. While Stevens-Johnson syndrome is a rare side effect of metronidazole, a photosensitive rash is not typically observed.
Metronidazole is an antibiotic that functions by producing reactive cytotoxic metabolites within bacteria. This medication can cause adverse effects such as a disulfiram-like reaction when combined with alcohol and an increased anticoagulant effect when taken with warfarin.

A 32-year-old man with cystic fibrosis (CF) has been experiencing a significant increase in productive cough with large amounts of sputum, occasional haemoptysis and difficulty breathing for the past few months.
What is the most probable diagnosis?Your Answer: Bronchiectasis
Explanation:Identifying Bronchiectasis in a Patient with Cystic Fibrosis
Cystic Fibrosis (CF) is a genetic disorder that can lead to the development of bronchiectasis. Bronchiectasis is a condition characterized by dilated, thick-walled bronchi, which can result from continual or recurrent infection and inflammation caused by thick, difficult to expectorate mucus in patients with CF. In contrast, bronchiolitis is an acute lower respiratory infection that occurs in children aged <2 years, while asthma typically presents with variable wheeze, cough, breathlessness, and chest tightness. Chronic obstructive pulmonary disease (COPD) typically develops in smokers aged >40, and interstitial lung disease generally affects patients aged >45 and is associated with persistent breathlessness on exertion and cough. Therefore, in a patient with CF presenting with symptoms such as cough, breathlessness, and chest infections, bronchiectasis should be considered as a possible diagnosis.

A 52-year-old man has recently been diagnosed with type 2 diabetes mellitus. He was prescribed medication but a few days later he complained of stomach cramps and loose stools.
Which of the following medications is most likely responsible for these symptoms?Your Answer: Metformin
Explanation:Side Effects of Common Oral Diabetic Medications
Managing diabetes often involves the use of oral medications to help control blood sugar levels. However, these medications can come with side effects that need to be considered when choosing a treatment plan. Here are some common side effects of four oral diabetic medications:
Metformin: The most common side effects of metformin are abdominal pain, anorexia, diarrhea, nausea, taste disturbance, and vomiting. There is also a risk of developing lactic acidosis, particularly in patients with a history of heart failure and concomitant use of drugs that can acutely impair renal function.
Furosemide: Furosemide is a less likely option due to its potential to exacerbate diabetes and cause hypokalemia, which can be dangerous in certain patients. It can also cause urinary retention in patients with enlarged prostates.
Gliclazide: Gliclazide can encourage weight gain and may cause hypoglycemia if the dosage is excessive.
Pioglitazone: Pioglitazone should be used with caution in patients with cardiovascular disease or in combination with insulin due to an increased risk of heart failure, particularly in elderly people.
It is important to be familiar with these side effects to ensure patient compliance with medication and to choose the most appropriate treatment plan for each individual.

A 42-year-old man presents with a six-month history of anorexia and weight loss, excess pigmentation and dizziness on standing. He has a previous history of autoimmune hypothyroidism that is managed with thyroxine.
Examination reveals postural hypotension and skin discolouration. Initial investigations reveal hyponatraemia: Na+ 118 mmol/l (135-145 mmol/l) and hyperkalaemia: K+ 5.6 mmol/l (normal range: 3.6-5.2 mmol/l).
Which of the following tests will be most useful to confirm the diagnosis?Your Answer: Short Synacthen® test
Explanation:Diagnosis and Management of Adrenal Failure: The Short Synacthen® Test
Adrenal failure is a condition characterized by multiple signs and symptoms and abnormal biochemistry. The diagnosis of adrenal failure is established by a failure of the plasma cortisol concentration to increase in response to adrenocorticotropic hormone (ACTH). The short corticotropin test is the gold standard diagnostic tool for this condition. If this test is not possible, an initial screening procedure comprising the measurement of morning plasma ACTH and cortisol levels is recommended. Diagnosis of the underlying cause should include a validated assay of autoantibodies against 21-hydroxylase. Treatment involves once-daily fludrocortisone and hydrocortisone or prednisolone. Follow-up should aim at monitoring appropriate dosing of corticosteroids and associated autoimmune diseases, particularly autoimmune thyroid disease. Serum urea and ESR may not be diagnostic, while serum calcium and thyroid function tests can be abnormal in untreated Addison’s disease. This article discusses the diagnosis and management of adrenal failure, with a focus on the short Synacthen® test.

A 21-year-old female medical student, who is an insulin-dependent diabetic, went on a weekend trip to visit some friends at another university. She forgot to pack her insulin. When she returned, she went to visit her General Practitioner. Which of the following blood results would be expected?
Your Answer: Below normal glucagon levels
Correct Answer: Unchanged haemoglobin A1c (HbA1c)
Explanation:Insulin-dependent diabetes patients rely on insulin to regulate their blood glucose levels. Without insulin, several physiological changes occur. However, these changes do not happen immediately. Here are some effects of insulin absence in insulin-dependent diabetes patients:
Unchanged HbA1c levels – Correct: HbA1c levels do not change significantly over two to three days without insulin. Changes in HbA1c levels are observed over weeks and months.
Below normal fatty acid levels – Incorrect: In the absence of insulin, triglyceride hydrolysis and increased release from adipose tissue occur, giving raised fatty acid levels. Fatty acids are utilised to synthesise ketones.
Below normal glucagon levels – Incorrect: The body responds to the absence of insulin by increasing glucagon levels. In a healthy individual, this raised glucagon would raise glucose levels in the bloodstream, providing target organs with utilisable glucose. However, in a diabetic patient, the absence of insulin means target organs are still not able to utilise this resource.
Hypoglycaemia – Incorrect: In the absence of insulin, hyperglycaemia would be expected to develop. Ketones are generated by the body as an alternative energy source to glucose, since to utilise glucose, insulin is required.
Undetectable ketones – Incorrect: A diabetic patient who is normally dependent on insulin is at risk of developing diabetic ketoacidosis (DKA) even with only a weekend of missed insulin doses.

A 29-year-old female presents to the emergency department with lower abdominal pain. A pregnancy test and ultrasound confirms a tubal ectopic pregnancy measuring 32mm and associated with a foetal heartbeat. The patient has no past medical history of note. Her observations show:
Respiratory rate of 15 breaths/min
Pulse of 93 beats/min
Temperature of 36.7ºC
Blood pressure of 126/78 mmHg
Oxygen saturations of 96% on room air
What is the most appropriate management for this patient?Your Answer: Salpingectomy
Explanation:If a foetal heartbeat is detected on ultrasound in the case of an ectopic pregnancy, surgical management is necessary, and the appropriate procedure is a salpingectomy. This is the recommended course of action for a patient with no significant medical history and both fallopian tubes. Expectant management is not suitable in this scenario, as the foetal heartbeat is visible on ultrasound. Medical management with methotrexate is also not an option due to the foetal heartbeat, and mifepristone is not used for ectopic pregnancies.
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.

A 62-year-old woman presents to the General Practitioner. She has a past medical history of hypertension, diabetes mellitus type II, peripheral vascular disease and ischaemic heart disease. The patient had an episode of retinal artery occlusion (RAO) and had to go to the Eye Hospital as an emergency.
After many investigations, the Ophthalmologist stated that the cause of her RAO is atherosclerosis of her central retinal artery (CRA). The patient is worried about her eyesight becoming worse and asks about long-term management plans for RAO.
Which of the following is considered part of the long-term management plan for RAO?
Select the SINGLE most appropriate management from the list below.
Your Answer: Prophylaxis with an antiplatelet agent
Explanation:Retinal artery occlusion is a condition that increases the risk of ischemic end-organ damage, such as stroke. Long-term management involves identifying and addressing underlying causes, reducing risk factors for atherosclerosis, and considering carotid endarterectomy if necessary. Ophthalmic follow-up and referral to low-vision-aid clinics may also be necessary. Acute treatment options include ocular massage, intra-arterial fibrinolysis, and lowering intraocular pressure with anterior chamber paracentesis. Atherosclerosis and embolism are the main causes of RAO, and prophylaxis with an antiplatelet or anticoagulation agent may be necessary for long-term management. However, even with early treatment, the prognosis is generally poor, and only about one-third of patients show any improvement.

What advice should you give a young adult (who is NOT pregnant) if they ask what is the recommended amount of alcohol they can consume?
Your Answer: No more than 14 units of alcohol per week. If you do drink as much as 14 units per week, it is best to spread this evenly over 3 days or more
Explanation: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 25-year-old female patient complains of red, itchy, and sore eyelids with crusts on the eyelashes and a gritty feeling in both eyes. What is the primary treatment for this condition?
Your Answer: Eyelid hygiene with warm compresses, lid massage and lid margin cleaning
Explanation:The initial step in treating blepharitis is to apply hot compresses to the affected area. This is followed by eyelid hygiene, which involves cleaning the lid margins and massaging them. If this does not work, chloramphenicol eye drops and oral antibiotics may be prescribed. Oily tear eye drops can be used to prevent rapid evaporation of tears caused by blepharitis. While an omega-3 rich diet may help improve the condition, it is not considered a first-line treatment.
Blepharitis is a condition where the eyelid margins become inflamed. This can be caused by dysfunction of the meibomian glands (posterior blepharitis) or seborrhoeic dermatitis/staphylococcal infection (anterior blepharitis). It is more common in patients with rosacea. The meibomian glands secrete oil to prevent rapid evaporation of the tear film, so any problem affecting these glands can cause dryness and irritation of the eyes. Symptoms of blepharitis are usually bilateral and include grittiness, discomfort around the eyelid margins, sticky eyes in the morning, and redness of the eyelid margins. Styes and chalazions are also more common in patients with blepharitis, and secondary conjunctivitis may occur.
Management of blepharitis involves softening the lid margin with hot compresses twice a day and practicing lid hygiene to remove debris from the lid margins. This can be done using cotton wool buds dipped in a mixture of cooled boiled water and baby shampoo or sodium bicarbonate in cooled boiled water. Artificial tears may also be given for symptom relief in people with dry eyes or an abnormal tear film.

A 55-year-old woman presents with weight loss and anaemia. She has no significant medical history. Upon examination, she has massive splenomegaly and pale conjunctivae. Her full blood count shows a Hb of 10.9 g/dl, platelets of 702 * 109/l, and a WCC of 56.6 * 109/l. Leucocytosis is noted on her film, with all stages of granulocyte maturation seen. What is the most probable diagnosis?
Your Answer: Acute myeloid leukaemia
Correct Answer: Chronic myeloid leukaemia
Explanation:Massive splenomegaly can be caused by myelofibrosis, chronic myeloid leukemia, visceral leishmaniasis (kala-azar), malaria, and Gaucher’s syndrome. Among these, chronic myeloid leukemia is the most probable diagnosis, as it is the most common cause.
Understanding Chronic Myeloid Leukaemia and its Management
Chronic myeloid leukaemia (CML) is a type of cancer that affects the blood and bone marrow. It is characterized by the presence of the Philadelphia chromosome in more than 95% of patients. This chromosome is formed due to a translocation between chromosomes 9 and 22, resulting in the fusion of the ABL proto-oncogene and the BCR gene. The resulting BCR-ABL gene produces a fusion protein that has excessive tyrosine kinase activity.
CML typically affects individuals between 60-70 years of age and presents with symptoms such as anaemia, weight loss, sweating, and splenomegaly. The condition is also associated with an increase in granulocytes at different stages of maturation and thrombocytosis. In some cases, CML may undergo blast transformation, leading to acute myeloid leukaemia (AML) or acute lymphoblastic leukaemia (ALL).
The management of CML involves various treatment options, including imatinib, which is considered the first-line treatment. Imatinib is an inhibitor of the tyrosine kinase associated with the BCR-ABL defect and has a very high response rate in the chronic phase of CML. Other treatment options include hydroxyurea, interferon-alpha, and allogenic bone marrow transplant. With proper management, individuals with CML can lead a normal life.

You are evaluating a patient who is experiencing hip discomfort. Do you suspect osteoarthritis as the diagnosis? If so, what signs or symptoms would warrant additional testing for a different diagnosis?
Your Answer: Morning stiffness lasting 4 hours
Explanation:If morning stiffness persists for more than 2 hours, it could be a sign of inflammatory arthritis and should be investigated further.
Osteoarthritis (OA) of the hip is a prevalent condition, with the knee being the only joint more commonly affected. It is particularly prevalent in older individuals, and women are twice as likely to develop it. Obesity and developmental dysplasia of the hip are also risk factors. The condition is characterized by chronic groin pain that is exacerbated by exercise and relieved by rest. However, if the pain is present at rest, at night, or in the morning for more than two hours, it may indicate an alternative cause. The Oxford Hip Score is a widely used tool to assess the severity of the condition.
If the symptoms are typical, a clinical diagnosis can be made. Otherwise, plain x-rays are the first-line investigation. Management of OA of the hip includes oral analgesia and intra-articular injections, which provide short-term relief. However, total hip replacement is the definitive treatment.
Total hip replacement is a common operation in the developed world, but it is not without risks. Perioperative complications include venous thromboembolism, intraoperative fracture, nerve injury, surgical site infection, and leg length discrepancy. Postoperatively, posterior dislocation may occur during extremes of hip flexion, presenting with a clunk, pain, and inability to weight bear. Aseptic loosening is the most common reason for revision, and prosthetic joint infection is also a potential complication.

A 72-year-old man presents to the emergency department with his spouse reporting weakness in his right arm and leg, decreased vision, and difficulty speaking. The symptoms began approximately 30 minutes ago, and his wife promptly called for an ambulance. A CT scan of the head ruled out a hemorrhagic stroke, but a CT contrast angiography revealed a confirmed blockage in the proximal anterior circulation. What is the appropriate acute management for this patient?
Your Answer: Alteplase alone
Correct Answer: Alteplase plus thrombectomy
Explanation:For patients with an acute ischaemic stroke who present within 4.5 hours, the recommended treatment is a combination of thrombolysis and thrombectomy. Thrombolysis involves the use of alteplase, a tissue plasminogen activator that breaks down the clot, while thrombectomy physically removes the clot using a specialized device inserted through the femoral artery. In this case, as the patient has confirmed occlusion of the proximal anterior circulation, both thrombolysis and thrombectomy should be performed together for the best possible outcome. While alteplase alone can be considered if thrombectomy is not available, a better prognosis is more likely with the combination treatment. It would not be appropriate to perform thrombectomy alone without considering thrombolysis, as the patient is presenting within the window for thrombolysis and should be considered for both in combination according to the guidelines.
The Royal College of Physicians (RCP) and NICE have published guidelines on the diagnosis and management of patients following a stroke. The management of acute stroke includes maintaining normal levels of blood glucose, hydration, oxygen saturation, and temperature. Blood pressure should not be lowered in the acute phase unless there are complications. Aspirin should be given as soon as possible if a haemorrhagic stroke has been excluded. Anticoagulants should not be started until brain imaging has excluded haemorrhage. Thrombolysis with alteplase should only be given if administered within 4.5 hours of onset of stroke symptoms and haemorrhage has been definitively excluded. Mechanical thrombectomy is a new treatment option for patients with an acute ischaemic stroke. NICE recommends thrombectomy for people who have acute ischaemic stroke and confirmed occlusion of the proximal anterior circulation demonstrated by computed tomographic angiography or magnetic resonance angiography. Secondary prevention includes the use of clopidogrel and dipyridamole. Carotid artery endarterectomy should only be considered if carotid stenosis is greater than 70% according to ECST criteria or greater than 50% according to NASCET criteria.
