A 79-year-old male patient has a home visit from his general practitioner for follow-up after sustaining fractured neck of femur slipping on ice. He reports to feel well in himself and is progressing with the rehabilitation programme advised to him at discharge and is not reliant on analgesia any longer. He had no previous medical or surgical history prior to the fall. The patient would like some advice regarding preventing future fractures.
Which, of the options below, is appropriate?Your Answer: Refer for DEXA scan prior to any prescription
Correct Answer: Prescription of alendronate
Explanation:In patients aged 75 years or older who have experienced a fragility fracture, alendronate should be initiated without delay, even in the absence of a DEXA scan. This patient meets the NICE criteria for bisphosphonate treatment, and while a calcium-rich diet and supplementation may be helpful, they are not sufficient for managing osteoporosis. Zoledronic acid may be considered if the patient cannot tolerate bisphosphonates, but it should not be the first-line treatment.
Managing Osteoporosis in Patients with Fragility Fracture
The management of patients with fragility fractures depends on their age. For patients aged 75 years and above, they are presumed to have underlying osteoporosis and should be started on first-line therapy, which is an oral bisphosphonate, without the need for a DEXA scan. However, the 2014 NOGG guidelines suggest that treatment should be started in all women over the age of 50 years who’ve had a fragility fracture, although BMD measurement may sometimes be appropriate, particularly in younger postmenopausal women.
On the other hand, for patients below 75 years old, a DEXA scan should be arranged to determine their ongoing fracture risk. The results of the scan can be entered into a FRAX assessment, along with the fact that they’ve had a fracture, to determine the appropriate management plan. For instance, if a 79-year-old woman sustains a Colles’ fracture, she is presumed to have osteoporosis and should be started on oral alendronate 70mg once weekly without a DEXA scan.
In summary, managing osteoporosis in patients with fragility fractures requires age consideration and appropriate assessment to determine the best management plan.

A 42-year-old female patient visits the GP clinic with two circular patches on her scalp that have resulted in hair loss and scarring. She reports that she first noticed these patches 4 weeks after returning from a trip to Italy. Upon further inquiry, she also acknowledges experiencing persistent joint pain and stiffness. Could scarring alopecia be caused by any of the following?
Your Answer: Carbimazole
Correct Answer: Lichen planus
Explanation:Scarring alopecia can be caused by various factors such as trauma/burns, radiotherapy, discoid lupus, tinea capitis, and lichen planus. However, out of these options, lichen planus is the only cause that leads to scarring alopecia. The remaining causes, including alopecia areata, carbimazole, trichotillomania, and telogen effluvium, result in non-scarring alopecia.
Input:
Alopecia may be divided into scarring (destruction of hair follicle) and non-scarring (preservation of hair follicle). Scarring alopecia can be caused by trauma, burns, radiotherapy, lichen planus, discoid lupus, and untreated tinea capitis. Non-scarring alopecia can be caused by male-pattern baldness, drugs such as cytotoxic drugs, carbimazole, heparin, oral contraceptive pill, and colchicine, nutritional deficiencies such as iron and zinc deficiency, autoimmune conditions such as alopecia areata, telogen effluvium, hair loss following a stressful period such as surgery, and trichotillomania.Output:
– Alopecia can be categorized into scarring and non-scarring types.
– Scarring alopecia is caused by trauma, burns, radiotherapy, lichen planus, discoid lupus, and untreated tinea capitis.
– Non-scarring alopecia is caused by male-pattern baldness, drugs such as cytotoxic drugs, carbimazole, heparin, oral contraceptive pill, and colchicine, nutritional deficiencies such as iron and zinc deficiency, autoimmune conditions such as alopecia areata, telogen effluvium, hair loss following a stressful period such as surgery, and trichotillomania. -

A 65-year-old man presents to the ophthalmology clinic with a complaint of gradual vision loss. During tonometry, his intraocular pressure is found to be 26mmHg and optic disc cupping is observed on fundoscopy. Visual field examination reveals peripheral visual loss. The physician prescribes timolol eye drops to be used twice daily. What is the mechanism of action of this medication?
Your Answer: Decrease production of aqueous fluid and increase uveoscleral outflow
Correct Answer: Decrease production of aqueous fluid
Explanation:Timolol, a beta blocker, is effective in treating primary open-angle glaucoma by reducing the production of aqueous fluid. This condition is characterized by increased intraocular pressure due to inefficient drainage of fluid in the eye’s trabecular meshwork. Symptoms include gradual loss of vision, particularly in the peripheral fields. Brimonidine, an alpha-adrenergic agonist, also reduces aqueous fluid production and increases uveoscleral outflow. However, drugs that decrease uveoscleral outflow or increase aqueous fluid production would worsen the patient’s condition. Glucocorticoids can cause reduced drainage of aqueous humour and are implicated in causing open-angle glaucoma. Latanoprost, a prostaglandin analogue, increases uveoscleral outflow.
Glaucoma is a condition where the optic nerve is damaged due to increased pressure in the eye. Primary open-angle glaucoma is a type where the iris is clear of the trabecular meshwork, which is responsible for draining aqueous humour from the eye. This results in increased resistance to outflow and raised intraocular pressure. The condition affects 0.5% of people over 40 years old and increases with age. Genetics also play a role, with first-degree relatives having a 16% chance of developing the disease. Symptoms are usually absent, and diagnosis is made through routine eye examinations. Investigations include visual field tests, tonometry, and slit lamp examinations. Treatment involves eye drops to lower intraocular pressure, with prostaglandin analogues being the first line of treatment. Surgery may be considered in refractory cases. Regular reassessment is necessary to monitor progression and prevent visual field loss.

A 32-year-old woman with Addison's disease is seen for a follow-up appointment. She reports a productive cough and feeling feverish for the past three days. Upon examination, her chest is clear, pulse is 84 beats per minute, and temperature is 37.7ºC. Due to her medical history, an antibiotic is prescribed.
What advice should be given regarding her adrenal replacement therapy?Your Answer: Double the hydrocortisone dose, keep the same fludrocortisone dose
Explanation:In the case of a patient with Addison’s disease who develops an additional illness, it is recommended to increase the dose of glucocorticoids while maintaining the same dose of fludrocortisone.
Addison’s disease is a condition that requires patients to undergo both glucocorticoid and mineralocorticoid replacement therapy. This treatment usually involves taking a combination of hydrocortisone and fludrocortisone. Hydrocortisone is typically given in 2 or 3 divided doses, with patients requiring 20-30 mg per day, mostly in the first half of the day. Patient education is crucial, and it is essential to emphasize the importance of not missing glucocorticoid doses. Additionally, patients should consider wearing MedicAlert bracelets and steroid cards, and they should be provided with hydrocortisone for injection with needles and syringes to treat an adrenal crisis.
During an intercurrent illness, it is crucial to manage the glucocorticoid dose properly. In simple terms, the glucocorticoid dose should be doubled, while the fludrocortisone dose should remain the same. The Addison’s Clinical Advisory Panel has produced guidelines that detail specific scenarios, and patients should refer to these guidelines for more information. It is essential to discuss how to adjust the glucocorticoid dose during an intercurrent illness with a healthcare professional. Proper management of Addison’s disease is crucial to ensure that patients can lead healthy and fulfilling lives.

Neuropathic pain typically does not improve with opioids. Nevertheless, if conventional treatments have been ineffective, which opioid should be considered for initiation in elderly patients?
Your Answer: Tramadol
Explanation:Understanding Neuropathic Pain and its Management
Neuropathic pain is a type of pain that occurs due to damage or disruption of the nervous system. It is a complex condition that is often difficult to treat and does not respond well to standard painkillers. Examples of neuropathic pain include diabetic neuropathy, post-herpetic neuralgia, trigeminal neuralgia, and prolapsed intervertebral disc.
To manage neuropathic pain, the National Institute for Health and Care Excellence (NICE) updated their guidance in 2013. The first-line treatment options include amitriptyline, duloxetine, gabapentin, or pregabalin. If the first-line drug treatment does not work, patients may try one of the other three drugs. Unlike standard painkillers, drugs for neuropathic pain are typically used as monotherapy, meaning that if they do not work, patients should switch to a different drug rather than adding another one.
Tramadol may be used as rescue therapy for exacerbations of neuropathic pain, while topical capsaicin may be used for localized neuropathic pain, such as post-herpetic neuralgia. Pain management clinics may also be useful for patients with resistant problems. However, it is important to note that for some specific conditions, such as trigeminal neuralgia, the guidance may vary, and carbamazepine may be used as a first-line treatment. Overall, understanding neuropathic pain and its management is crucial for improving the quality of life for patients suffering from this condition.

A 16-year-old young woman is completing a summer internship at a daycare center before applying to study medicine. She has received a full schedule of childhood vaccinations. Her primary complaints are difficulty swallowing, a sore throat, malaise, and a fever. Upon examination, she has 5-10 gray ulcers on her buccal mucosa. Additionally, she has a vesicular rash on her hands and feet.
What is the most probable cause of this clinical presentation?Your Answer: Herpes simplex infection
Correct Answer: Coxsackie virus infection
Explanation:Differential Diagnosis: Hand-Foot-and-Mouth Disease
Hand-foot-and-mouth disease is a viral illness caused by Coxsackie virus A type 16. It presents as a vesicular eruption in the mouth and can also involve the hands, feet, buttocks, and/or genitalia. Macular lesions on the buccal mucosa, tongue, and/or hard palate rapidly progress to vesicles that erode and become surrounded by an erythematous halo. Skin lesions, which present as tender macules or vesicles on an erythematous base, develop in approximately 75% of patients. Treatment is supportive, and there is no antiviral agent specific for the aetiological agents. Adequate fluid intake, preferably with cold drinks, is essential to prevent dehydration.
Other conditions that may present with similar symptoms include erythema multiforme, herpes simplex infection, gonorrhoea, and pemphigus erythematosus. However, the clinical presentation and causative agent of hand-foot-and-mouth disease distinguish it from these other conditions.

A 42-year-old man with a history of psoriasis develops plaques on his scalp. What is the most suitable treatment option among the following choices?
Your Answer: Hydrocortisone 1%
Explanation:It’s a challenging question, especially since the decision on psoriasis treatment often involves the patient and doctor’s preference. While vitamin D analogues can be an option, calcipotriol is not advisable due to its potential to cause irritation. Instead, calcitriol and tacalcitol can be considered. For facial psoriasis, mild potency topical steroids can be effective. However, coal tar may not be well-tolerated for facial application due to its unpleasant odor and messiness.
NICE recommends a step-wise approach for chronic plaque psoriasis, starting with regular emollients and then using a potent corticosteroid and vitamin D analogue separately, followed by a vitamin D analogue twice daily, and then a potent corticosteroid or coal tar preparation if there is no improvement. Phototherapy, systemic therapy, and topical treatments are also options for management. Topical steroids should be used cautiously and vitamin D analogues may be used long-term. Dithranol and coal tar have adverse effects but can be effective.

A 6-week-old infant presents to the clinic with a red rash on their scalp accompanied by yellow flakes. What is the probable diagnosis?
Your Answer: Seborrhoeic dermatitis
Explanation:Seborrhoeic Dermatitis in Children: Symptoms and Management
Seborrhoeic dermatitis is a common skin condition that affects children, typically appearing on the scalp, nappy area, face, and limb flexures. One of the earliest signs is cradle cap, which can develop in the first few weeks of life. This condition is characterized by a red rash with coarse yellow scales.
Fortunately, seborrhoeic dermatitis in children is not harmful and usually resolves within a few weeks. Parents can help manage the condition by massaging a topical emollient onto the scalp to loosen scales, brushing gently with a soft brush, and washing off with shampoo. If the condition is severe or persistent, a topical imidazole cream may be prescribed.
It’s important to note that seborrhoeic dermatitis in children tends to resolve spontaneously by around 8 months of age. Parents should not be overly concerned and can take comfort in knowing that this condition is common and easily managed. By following these simple steps, parents can help their child feel more comfortable and alleviate any discomfort associated with seborrhoeic dermatitis.

A 25-year-old man is brought into the emergency department resus, after being involved in a road traffic collision, where he, a motorbike rider, collided with a car. As one of the doctors receiving the patient into resus, you are tasked with calculating the current Glasgow coma score (GCS) of the patient. The patient's eyes are open, but he seems disoriented and asks you if he's on a spaceship.
Your Answer: 9
Correct Answer: 13
Explanation:The patient’s GCS score is 13, with a breakdown of 4 out of 4 for eye opening, 4 out of 5 for verbal response (due to confusion), and 5 out of 6 for motor response (exhibiting localisation to pain). A helpful mnemonic to remember this breakdown is 654…MoVE.
Understanding the Glasgow Coma Scale for Adults
The Glasgow Coma Scale (GCS) is a tool used to assess the level of consciousness in adults who have suffered a brain injury or other neurological condition. It is based on three components: motor response, verbal response, and eye opening. Each component is scored on a scale from 1 to 6, with a higher score indicating a better level of consciousness.
The motor response component assesses the patient’s ability to move in response to stimuli. A score of 6 indicates that the patient is able to obey commands, while a score of 1 indicates no movement at all.
The verbal response component assesses the patient’s ability to communicate. A score of 5 indicates that the patient is fully oriented, while a score of 1 indicates no verbal response at all.
The eye opening component assesses the patient’s ability to open their eyes. A score of 4 indicates that the patient is able to open their eyes spontaneously, while a score of 1 indicates no eye opening at all.
The GCS score is expressed as a combination of the scores from each component, with the motor response score listed first, followed by the verbal response score, and then the eye opening score. For example, a GCS score of 13, M5 V4 E4 at 21:30 would indicate that the patient had a motor response score of 5, a verbal response score of 4, and an eye opening score of 4 at 9:30 PM.
Overall, the Glasgow Coma Scale is a useful tool for healthcare professionals to assess the level of consciousness in adults with neurological conditions.

A 74-year-old woman is being evaluated after taking oral flucloxacillin for cellulitis in her right lower limb. The local protocol recommends using oral clindamycin as the next line of treatment. What is the most crucial side effect of clindamycin that she should be cautioned about?
Your Answer: Diarrhoea
Explanation:The use of clindamycin as a treatment is strongly linked to an increased likelihood of contracting C. difficile.
Clostridioides difficile is a type of bacteria that is commonly found in hospitals. It is a Gram positive rod that produces an exotoxin which can cause damage to the intestines, leading to a condition called pseudomembranous colitis. This bacteria usually develops when the normal gut flora is suppressed by broad-spectrum antibiotics, with second and third generation cephalosporins being the leading cause of C. difficile. Other risk factors include proton pump inhibitors. Symptoms of C. difficile include diarrhea, abdominal pain, and a raised white blood cell count. The severity of the infection can be determined using the Public Health England severity scale, which ranges from mild to life-threatening.
To diagnose C. difficile, a stool sample is tested for the presence of C. difficile toxin (CDT). Treatment for a first episode of C. difficile infection typically involves oral vancomycin for 10 days, with fidaxomicin or a combination of oral vancomycin and IV metronidazole being used as second and third-line therapies. Recurrent infections occur in around 20% of patients, increasing to 50% after their second episode. In such cases, oral fidaxomicin is recommended within 12 weeks of symptom resolution, while oral vancomycin or fidaxomicin can be used after 12 weeks. For life-threatening C. difficile infections, oral vancomycin and IV metronidazole are used, and surgery may be considered with specialist advice. Other therapies, such as bezlotoxumab and fecal microbiota transplant, may also be considered for preventing recurrences in certain cases.

A 78-year-old man with known metastatic prostate cancer presents to his General Practitioner with generalised pain. He states that he has always had aches and pains from old age, but that this is different: he can feel the pain particularly in his back at night.
What is the most likely site to be involved in bone metastasis in this patient?Your Answer: Spine
Explanation:Common Sites of Metastatic Spread in Bone
Metastatic spread to the bone is a common occurrence in many types of cancer. The following are some of the most common sites of metastases in bone:
Spine: The spine is the most common site for bony metastases, with spread often found from a range of solid and haematological cancers, as well as infectious diseases such as tuberculosis.
Ribs: While breast cancer is known to spread to the ribs, this is not the case for many other cancers.
Pelvis: The pelvis is a prevalent site of metastatic spread occurring mostly from the prostate, breast, kidney, lung, and thyroid cancer.
Skull: Skull metastases are seen in 15-25% of all cancer patients and tend to include those from the breast, lungs, prostate, and thyroid, as well as melanoma.
Long bones: Localised bone pain is a red flag for metastatic spread to any of the long bones such as the femur and humerus. Breast, prostate, renal, thyroid, and lung cancers frequently metastasize to these areas.
Overall, understanding the common sites of metastatic spread in bone can help with early detection and treatment of cancer.

A 28-year-old woman comes in for a check-up. She has a history of perianal abscess, but no other significant medical issues. Over the past few months, she has visited the Emergency Department twice due to persistent abdominal pain. She has also experienced occasional episodes of bloody diarrhea. Blood tests reveal microcytic anemia and mild hypokalemia. Her albumin levels are low, but her liver function tests are normal. Barium imaging shows a small bowel stricture with evidence of mucosal ulceration, as well as normal-looking mucosa and skip pattern lesions. Based on these symptoms, what is the most likely diagnosis?
Your Answer: Ulcerative colitis
Correct Answer: Crohn's disease
Explanation:Differential Diagnosis of Chronic Diarrhoea with Abdominal Pain and Weight Loss
Chronic diarrhoea with abdominal pain and weight loss can be indicative of various gastrointestinal disorders. A thorough differential diagnosis is necessary to determine the underlying cause.
Crohn’s Disease: This inflammatory bowel disease can affect any part of the gastrointestinal tract and is characterized by prolonged diarrhoea with abdominal pain, weight loss, and fatigue. Diarrhoea is usually not bloody, but if the colon is involved, patients may report diffuse abdominal pain accompanied by mucus, blood, and pus in the stool. Serologic tests such as ASCA and p-ANCA can help differentiate Crohn’s disease from other conditions.
Ulcerative Colitis: Unlike Crohn’s disease, UC involves only the large bowel and is characterized by rectal bleeding, frequent stools, and mucus discharge from the rectum. Sigmoidoscopy can confirm the diagnosis.
Small Bowel Lymphoma: MALTomas can occur in various gastrointestinal sites, but most patients have no physical findings.
Coeliac Disease: This chronic disorder results in an inability to tolerate gliadin and is characterized by electrolyte imbalances, evidence of malnutrition, and anaemia. Diarrhoea is the most common symptom, with characteristic foul-smelling stools.
Tropical Sprue: This syndrome is characterized by acute or chronic diarrhoea, weight loss, and nutrient malabsorption and occurs in residents or visitors to the tropics and subtropics. However, it is not suggestive in the absence of a history of foreign travel.
In conclusion, a thorough evaluation of symptoms and diagnostic tests is necessary to differentiate between these gastrointestinal disorders and determine the appropriate treatment plan.

Each one of the following is typical of optic neuritis, except for:
Your Answer: Poor discrimination of colours, 'red desaturation'
Correct Answer: Sudden onset of visual loss
Explanation:It is rare for optic neuritis to cause sudden visual loss, as the typical progression of visual loss occurs over a period of days rather than hours.
Optic neuritis is a condition that can be caused by multiple sclerosis, diabetes, or syphilis. It is characterized by a decrease in visual acuity in one eye over a period of hours or days, as well as poor color discrimination and pain that worsens with eye movement. Other symptoms include a relative afferent pupillary defect and a central scotoma. The condition can be diagnosed through an MRI of the brain and orbits with gadolinium contrast. Treatment typically involves high-dose steroids, and recovery usually takes 4-6 weeks. If an MRI shows more than three white-matter lesions, the risk of developing multiple sclerosis within five years is approximately 50%.

A 30-year-old male with a history of ankylosing spondylitis presents to his GP with complaints of eye pain and sensitivity to light. He wears glasses for nearsightedness and this is his first occurrence, affecting only his right eye. Upon examination, his right eye has a visual acuity of 6/6 while his left eye is corrected to 6/18. The left pupil is misshapen and the eye is red, but the cornea appears clear. What is the most likely diagnosis for this patient?
Your Answer: Anterior uveitis
Explanation:Ankylosing spondylitis is commonly associated with anterior uveitis, which presents with symptoms such as a misshapen pupil, red eye, and reduced vision. This condition involves both eyes and is more likely than other eye conditions. Retinal detachment does not cause eye pain.
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.

You assess a 75-year-old patient with a complex medical history and taking multiple medications. The patient presents with significant bilateral breast tissue growth. Which medication is the most probable cause of this condition?
Your Answer: Tamoxifen
Correct Answer: Goserelin (Zoladex)
Explanation:Gynaecomastia may occur as a side effect of using GnRH agonists like goserelin for prostate cancer management. Tamoxifen can be prescribed to address gynaecomastia.
Understanding Gynaecomastia: Causes and Drug Triggers
Gynaecomastia is a medical condition that occurs when males develop an abnormal amount of breast tissue. This condition is usually caused by an increased ratio of oestrogen to androgen. It is important to differentiate the causes of galactorrhoea, which is due to the actions of prolactin on breast tissue, from those of gynaecomastia.
There are several causes of gynaecomastia, including physiological changes that occur during puberty, syndromes with androgen deficiency such as Kallman’s and Klinefelter’s, testicular failure, liver disease, testicular cancer, ectopic tumour secretion, hyperthyroidism, and haemodialysis. Additionally, certain drugs can trigger gynaecomastia, with spironolactone being the most common drug cause. Other drugs that can cause gynaecomastia include cimetidine, digoxin, cannabis, finasteride, GnRH agonists like goserelin and buserelin, oestrogens, and anabolic steroids.
It is important to note that while drug-induced gynaecomastia is rare, there are still some drugs that can trigger this condition. Some of the very rare drug causes of gynaecomastia include tricyclics, isoniazid, calcium channel blockers, heroin, busulfan, and methyldopa. Understanding the causes and drug triggers of gynaecomastia can help individuals seek appropriate medical attention and treatment.

Select the SINGLE most probable diagnosis from the options below.Your Answer: Cholesteatoma
Correct Answer: Ménière’s disease
Explanation:Understanding Common Causes of Vertigo: Ménière’s Disease, BPPV, Acoustic Neuroma, Vestibular Neuritis, and Cholesteatoma
Vertigo is a common condition that can be caused by various factors. One of the most common causes is Ménière’s disease, which is characterized by a triad of symptoms including fluctuant hearing loss, vertigo, and tinnitus. Aural fullness may also be present. On the other hand, benign paroxysmal positional vertigo (BPPV) is induced by specific movements and is accompanied by nausea, light-headedness, and imbalance. Acoustic neuroma, on the other hand, presents with progressive ipsilateral tinnitus, sensorineural hearing loss, facial numbness, and giddiness. Vestibular neuritis, which follows a febrile illness, is characterized by sudden vertigo, vomiting, and prostration, while cholesteatoma tends to be asymptomatic in the early stages and is characterized by a foul-smelling discharge and conductive hearing loss. Management of vertigo includes self-care advice, medication, and referral to an ENT specialist to confirm the condition and exclude sinister causes.

A 49-year-old woman receives a red blood cell transfusion in the emergency department after a car accident. She develops a fever and becomes anxious after 30 minutes. The transfusion is stopped and the following observations are made: respiratory rate 21 breaths per minute, heart rate 74 bpm, saturations 98% (room air), blood pressure 125/85 mmHg, temperature 39ºC. The patient is comfortable at rest and chest auscultation reveals no wheezing. What is the most appropriate treatment for this patient's reaction?
Your Answer: Broad-spectrum antibiotics
Correct Answer: Paracetamol
Explanation:Complications of Blood Product Transfusion: Understanding the Risks
Blood product transfusion can lead to various complications that can be classified into different categories. Immunological complications include acute haemolytic reactions, non-haemolytic febrile reactions, and allergic/anaphylaxis reactions. Infective complications may also arise, including the transmission of vCJD. Other complications include transfusion-related acute lung injury (TRALI), transfusion-associated circulatory overload (TACO), hyperkalaemia, iron overload, and clotting.
Non-haemolytic febrile reactions are thought to be caused by antibodies reacting with white cell fragments in the blood product and cytokines that have leaked from the blood cell during storage. On the other hand, allergic reactions to blood transfusions are caused by hypersensitivity reactions to components within the transfusion. TRALI is a rare but potentially fatal complication of blood transfusion, while TACO is a relatively common reaction due to fluid overload resulting in pulmonary oedema.
It is important to understand the risks associated with blood product transfusion and to be aware of the different types of complications that may arise. Proper management and prompt treatment are crucial in preventing further harm to the patient.

A 16-year-old girl comes to the clinic with a palpable purpuric rash on her lower limbs and polyarthralgia after experiencing a recent sore throat. What is the probable diagnosis?
Your Answer: Measles
Correct Answer: Henoch-Schonlein purpura
Explanation:Understanding Henoch-Schonlein Purpura
Henoch-Schonlein purpura (HSP) is a type of small vessel vasculitis that is mediated by IgA. It is often associated with IgA nephropathy, also known as Berger’s disease. HSP is commonly observed in children following an infection.
The condition is characterized by a palpable purpuric rash, which is accompanied by localized oedema over the buttocks and extensor surfaces of the arms and legs. Other symptoms include abdominal pain, polyarthritis, and features of IgA nephropathy such as haematuria and renal failure.
Treatment for HSP involves analgesia for arthralgia, while management of nephropathy is generally supportive. There is inconsistent evidence for the use of steroids and immunosuppressants.
The prognosis for HSP is usually excellent, especially in children without renal involvement. The condition is self-limiting, but around one-third of patients may experience a relapse. It is important to monitor blood pressure and urinalysis to detect any progressive renal involvement.
Overall, understanding Henoch-Schonlein purpura is crucial for prompt diagnosis and management of the condition.

A 35-year-old woman visits her GP with concerns about not having had a period for 6 months. She has also noticed increased sweating at night and occasional hot flashes, but attributes this to the warm weather. She has no desire for children and is only seeking reassurance that there is no underlying issue causing her amenorrhea. She has no significant medical history or family history.
The following blood tests were conducted:
- TSH: 2 mU/L (normal range: 0.5 - 5.5)
- T4: 10 pmol/L (normal range: 9 - 18)
- Prolactin: 15 µg/L (normal range: <25)
- FSH: 75 iu/L (normal range: <40)
- Oestradiol: 45 pmol/L (normal range: >100)
Repeat blood tests 6 weeks later show no changes. What is the most appropriate course of action for this patient?Your Answer: No management is required
Correct Answer: Combined hormone replacement therapy until the age of 51
Explanation:Women with premature ovarian insufficiency should be offered hormone replacement therapy (HRT) or a combined oral contraceptive pill until the age of 51 years to manage symptoms of low estrogen, prevent osteoporosis, and protect against possible cardiovascular complications. As this patient has a uterus, combined replacement therapy is necessary to avoid the risk of endometrial cancer from unopposed estrogen. Therefore, the most appropriate answer is combined hormone replacement therapy until the age of 51. It is important to note that hormone replacement therapy should be offered to all women with premature ovarian failure to protect bone mineral density and manage symptoms of low estrogen. The progestogen-only pill alone is not sufficient as estrogen is needed to treat symptoms and promote bone mineral density, while progesterone is added to oppose estrogen and reduce the risk of endometrial cancer.
Premature Ovarian Insufficiency: Causes and Management
Premature ovarian insufficiency is a condition where menopausal symptoms and elevated gonadotrophin levels occur before the age of 40. It affects approximately 1 in 100 women and can be caused by various factors such as idiopathic reasons, family history, bilateral oophorectomy, radiotherapy, chemotherapy, infection, autoimmune disorders, and resistant ovary syndrome. The symptoms of premature ovarian insufficiency are similar to those of normal menopause, including hot flushes, night sweats, infertility, secondary amenorrhoea, raised FSH and LH levels, and low oestradiol.
Management of premature ovarian insufficiency involves hormone replacement therapy (HRT) or a combined oral contraceptive pill until the age of the average menopause, which is 51 years. It is important to note that HRT does not provide contraception in case spontaneous ovarian activity resumes. Early diagnosis and management of premature ovarian insufficiency can help alleviate symptoms and improve quality of life for affected women.

Question 20
Correct

A 28-year-old male came to the emergency department complaining of shortness of breath during exertion. He had no medical history to report. During the examination, a midsystolic murmur was detected, which was most audible at the left lower sternal border. The murmur became louder when the Valsalva manoeuvre was performed. An echocardiogram revealed mitral regurgitation, asymmetric hypertrophy, systolic anterior motion of the anterior mitral valve leaflet, and left ventricular outflow tract obstruction. What medication should be avoided in this patient?
Your Answer: Ramipril
Explanation:Patients with HOCM should avoid ACE-inhibitors.
The correct answer is Ramipril. In patients with hypertrophic obstructive cardiomyopathy (HOCM) and left ventricular outflow tract (LVOT) obstruction, ACE inhibitors are not recommended. This is because ACE inhibitors can decrease afterload, which may exacerbate the LVOT gradient. The patient in this case has echocardiographic evidence of HOCM, including asymmetric hypertrophy, systolic anterior motion of the anterior mitral valve leaflet, and mitral regurgitation.
However, amiodarone, atenolol, disopyramide, and verapamil are all viable treatment options for HOCM.
Hypertrophic obstructive cardiomyopathy (HOCM) is a genetic disorder that affects muscle tissue and is inherited in an autosomal dominant manner. It is estimated to have a prevalence of 1 in 500. The condition is caused by defects in the genes that encode contractile proteins.
The management of HOCM involves several approaches. Amiodarone is a medication that can be used to treat the condition. Beta-blockers or verapamil may also be prescribed to alleviate symptoms. In some cases, a cardioverter defibrillator or dual chamber pacemaker may be necessary. It is important to note that certain drugs, such as nitrates, ACE-inhibitors, and inotropes, should be avoided in patients with HOCM. Additionally, endocarditis prophylaxis may be recommended, although the 2008 NICE guidelines should be consulted for specific recommendations.

A 6-month-old girl has been brought in to the Emergency Department after an episode of rectal bleeding. Her parents tell you that she appears to be suffering from abdominal pain since this morning, drawing her legs up into the fetal position, and has eaten very little, which is unlike her. She vomited about three times and then passed bloody stools. When you ask for further details, the parents tell you that the stool was jelly-like red and very slimy. The parents started weaning the child one month ago and only give her baby food.
On examination, the child has right lower abdominal tenderness and her mucous membranes look dehydrated. Her capillary refill time is four seconds and you can vaguely feel some sort of mass in her right lower abdomen.
What is the most likely diagnosis?Your Answer: Campylobacter related gastroenteritis
Correct Answer: Intussusception
Explanation:Common Gastrointestinal Disorders in Toddlers
Intussusception is a common gastrointestinal disorder in toddlers, typically affecting those aged 9-12 months. Symptoms include slimy or jelly-like red stools, abdominal pain, and a palpable mass or fullness. Diagnosis is made through ultrasound imaging and treatment usually involves an enema, although surgery may be necessary in complicated cases.
Pyloric stenosis is another disorder that can occur in the first few weeks of a baby’s life. It causes forceful projectile vomiting immediately after feeds and is diagnosed through ultrasound imaging. Treatment involves surgery with a pyloromyotomy.
Campylobacter-related gastroenteritis is rare in toddlers, especially considering that they typically only consume baby food.
Colorectal cancer is almost unheard of in this age group.
Hirschsprung’s disease is a congenital disorder that causes bowel obstruction, resulting in vomiting and failure to pass stools. It is typically diagnosed through a rectal biopsy and treated with surgical removal of the affected part of the bowel.

A 32-year-old taxi driver presents with a frontal headache that has been ongoing for the past 2 weeks. After taking 3 blood pressure readings, the lowest of which is 168/98 mmHg, a 24-hour tape reveals an average blood pressure reading of 158/88mmHg. The patient is open to starting medication for hypertension but expresses concern about how this diagnosis will affect his job. What advice would you give him?
Your Answer: Advise him that he can continue working as long as he checks his blood pressure every 12 hours
Correct Answer: Advise him that he may continue driving as long as is blood pressure is not consistently above 180mmHg systolic or above 100mmHg diastolic
Explanation:Drivers of cars and motorcycles are not required to inform the DVLA of their hypertension, but they must refrain from driving if their symptoms would impair their ability to drive safely. The same guidelines apply to bus and lorry drivers, but if their resting blood pressure consistently exceeds 180 mmHg systolic or 100mmHg diastolic, they must cease driving and notify the DVLA.
DVLA Guidelines for Cardiovascular Disorders and Driving
The DVLA has specific guidelines for individuals with cardiovascular disorders who wish to drive a car or motorcycle. For those with hypertension, driving is permitted unless the treatment causes unacceptable side effects, and there is no need to notify the DVLA. However, for those with Group 2 Entitlement, a resting blood pressure consistently at 180 mmHg systolic or more and/or 100 mm Hg diastolic or more disqualifies them from driving.
Individuals who have undergone elective angioplasty must refrain from driving for one week, while those who have undergone CABG or acute coronary syndrome must refrain from driving for four weeks. However, if successfully treated by angioplasty, driving is permitted after one week. Those with angina must cease driving if symptoms occur at rest or while driving.
For individuals who have undergone pacemaker insertion, they must refrain from driving for one week. If they have an implantable cardioverter-defibrillator (ICD) for sustained ventricular arrhythmia, they must cease driving for six months. If the ICD is implanted prophylactically, they must cease driving for one month, and having an ICD results in a permanent bar for Group 2 drivers. Successful catheter ablation for an arrhythmia requires two days off driving.
Individuals with an aortic aneurysm of 6cm or more must notify the DVLA, and licensing will be permitted subject to annual review. However, an aortic diameter of 6.5 cm or more disqualifies patients from driving. Those who have undergone a heart transplant must refrain from driving for six weeks, but there is no need to notify the DVLA.

A 67-year-old man visits his doctor with a complaint of a rash on his face. Upon examination, the doctor observes a vesicular rash around the left orbit and on the bridge of the nose. The patient reports experiencing pain. The eye appears unaffected and is not inflamed. The doctor suspects shingles.
What would be the best course of action?Your Answer: Start oral aciclovir only
Correct Answer: Urgent referral to ophthalmology and start oral aciclovir
Explanation:Immediate ophthalmological assessment and a 7-10 day course of oral antivirals are necessary for the treatment of herpes zoster ophthalmicus. Hutchinson’s sign, which involves the tip of the nose, is a strong indicator of ocular involvement and warrants urgent referral to an ophthalmologist. While oral corticosteroids may help alleviate pain, they are not as crucial as antivirals or ophthalmological evaluation.
Herpes Zoster Ophthalmicus: Symptoms, Treatment, and Complications
Herpes zoster ophthalmicus (HZO) is a condition that occurs when the varicella-zoster virus reactivates in the area supplied by the ophthalmic division of the trigeminal nerve. It is responsible for approximately 10% of shingles cases. The main symptom of HZO is a vesicular rash around the eye, which may or may not involve the eye itself. Hutchinson’s sign, a rash on the tip or side of the nose, is a strong indicator of nasociliary involvement and increases the risk of ocular involvement.
Treatment for HZO involves oral antiviral medication for 7-10 days, ideally started within 72 hours of symptom onset. Intravenous antivirals may be necessary for severe infections or immunocompromised patients. Topical antiviral treatment is not recommended for HZO, but topical corticosteroids may be used to treat any secondary inflammation of the eye. Ocular involvement requires urgent ophthalmology review to prevent complications such as conjunctivitis, keratitis, episcleritis, anterior uveitis, ptosis, and post-herpetic neuralgia.
In summary, HZO is a condition caused by the reactivation of the varicella-zoster virus in the ophthalmic division of the trigeminal nerve. It presents with a vesicular rash around the eye and may involve the eye itself. Treatment involves oral antiviral medication and urgent ophthalmology review is necessary for ocular involvement. Complications of HZO include various eye conditions, ptosis, and post-herpetic neuralgia.

A 38-year-old woman underwent bowel resection and 48 hours post-operation, she became breathless, tachycardic, tachypnoeic and complained of pleuritic chest pain.
Which of the following is the most definitive investigation to request?Your Answer: Positron emission tomography (PET)/CT of the chest
Correct Answer: CT pulmonary angiogram (CTPA)
Explanation:Diagnostic Tests for Pulmonary Embolism: A Comparison
Pulmonary embolism (PE) is a serious medical condition that requires prompt diagnosis and treatment. There are several diagnostic tests available for PE, but not all are equally effective. Here, we compare the most commonly used tests and their suitability for diagnosing PE.
CT pulmonary angiogram (CTPA) is the gold standard diagnostic test for PE. It is highly sensitive and specific, making it the most definitive investigation for PE. Patients with a history of recent surgery and subsequent symptoms pointing towards PE should undergo a CTPA.
Electrocardiography (ECG) is not a first-line diagnostic test for PE. Although classic ECG changes may occur in some patients with PE, they are not specific to the condition and may also occur in individuals without PE.
Chest radiograph is less definitive than CTPA for diagnosing PE. While it may show some abnormalities, many chest radiographs are normal in PE. Therefore, it is not a reliable test for diagnosing PE.
Echocardiogram may show right-sided heart dysfunction in very large PEs, but it is not a first-line diagnostic test for PE and is not definitive in the investigation of PE.
Positron emission tomography (PET)/CT of the chest is not recommended for the investigation of PE. It is a radioisotope functional imaging technique used in the imaging of tumours and neuroimaging, but not for diagnosing PE.
In conclusion, CTPA is the most definitive diagnostic test for PE and should be used in patients with a high suspicion of the condition. Other tests may be used in conjunction with CTPA or in specific cases, but they are not as reliable or definitive as CTPA.

Given the likely diagnosis, which of the following is the best treatment option?
Select the SINGLE best treatment option from the list below.
Your Answer: Oral steroids for three months
Correct Answer: NSAIDs until symptomatic resolution along with colchicine for three months
Explanation:Treatment Options for Acute Pericarditis
Acute pericarditis requires prompt treatment to prevent complications such as recurrent pericarditis, pericardial effusions, cardiac tamponade, and chronic constrictive pericarditis. The initial treatment for idiopathic or viral pericarditis involves high-dose non-steroidal anti-inflammatory drugs (NSAIDs) or aspirin in combination with colchicine. The duration of NSAID or aspirin treatment depends on symptom resolution and normalization of C-reactive protein (CRP), while colchicine treatment is continued for three months using a low, weight-adjusted dose. Strenuous physical activity should be restricted until symptom resolution and normalization of inflammatory markers, and gastroprotection with a proton-pump inhibitor is recommended.
If NSAIDs and colchicine are contraindicated, low-dose corticosteroids are the next step in the treatment algorithm, after exclusion of infectious causes. However, when the cause of the pericarditis is known, it must be treated first before starting anti-inflammatory treatment.

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.

A 25-year-old man complains of recurring headaches. He experiences these headaches about 2-3 times per month. The headaches are severe and occur on the right side of his head. They are throbbing in nature and last for approximately 8-12 hours. During these episodes, he finds it difficult to continue working and prefers to rest in a dark room. Paracetamol has not been effective in relieving his symptoms. What medication should be prescribed to decrease the frequency of these headaches?
Your Answer: Carbamazepine
Correct Answer: Propranolol
Explanation:For the acute treatment of migraine, a combination of triptan and NSAID or triptan and paracetamol is recommended. Prophylaxis options include topiramate or propranolol. In this case, the patient’s history is consistent with migraine and prophylaxis with propranolol or topiramate should be considered. Zolmitriptan is not indicated for prophylaxis, but rather for acute treatment of migraine.
Managing Migraines: Guidelines and Treatment Options
Migraines can be debilitating and affect a significant portion of the population. To manage migraines, it is important to understand the different treatment options available. According to the National Institute for Health and Care Excellence (NICE) guidelines, acute treatment for migraines involves a combination of an oral triptan and an NSAID or paracetamol. For young people aged 12-17 years, a nasal triptan may be preferred. If these measures are not effective, non-oral preparations of metoclopramide or prochlorperazine may be considered, along with a non-oral NSAID or triptan.
Prophylaxis should be given if patients are experiencing two or more attacks per month. NICE recommends topiramate or propranolol, depending on the patient’s preference, comorbidities, and risk of adverse events. Propranolol is preferred in women of childbearing age as topiramate may be teratogenic and reduce the effectiveness of hormonal contraceptives. Acupuncture and riboflavin may also be effective in reducing migraine frequency and intensity for some people. For women with predictable menstrual migraines, frovatriptan or zolmitriptan may be recommended as a type of mini-prophylaxis.
Specialists may consider other treatment options, such as candesartan or monoclonal antibodies directed against the calcitonin gene-related peptide (CGRP) receptor, like erenumab. However, pizotifen is no longer recommended due to common adverse effects like weight gain and drowsiness. It is important to exercise caution with young patients as acute dystonic reactions may develop. By following these guidelines and considering various treatment options, migraines can be effectively managed.

A 35-year-old man attends morning surgery complaining of ringing in his left ear, with occasional vertigo. His coworkers have recently commented that he speaks loudly on the phone. On examination his tympanic membranes appear normal.
Which of the following is the most probable diagnosis?
Your Answer: Benign paroxysmal positional vertigo (BPPV)
Correct Answer: Ménière’s disease
Explanation:Understanding Ménière’s Disease: Symptoms, Diagnosis, and Management
Ménière’s disease is a progressive inner ear disorder that can cause a triad of symptoms including fluctuant hearing loss, vertigo, and tinnitus. Aural fullness may also be present. In contrast, benign paroxysmal positional vertigo (BPPV) is characterized by brief episodes of vertigo induced by specific movements, while cholesteatoma typically presents with recurrent ear discharge, conductive hearing loss, and ear discomfort. Presbyacusis, or age-related hearing loss, is not the most likely diagnosis in this case. Although impacted ear wax can cause similar symptoms, normal tympanic membranes suggest that Ménière’s disease is more likely.
Diagnosis of Ménière’s disease is based on a history of at least two spontaneous episodes of vertigo lasting 20 minutes each, along with tinnitus and/or a sense of fullness in the ear canal, and confirmed sensorineural hearing loss on audiometry. Management includes self-care advice such as vestibular rehabilitation, medication such as prochlorperazine for acute attacks and betahistine for prevention, and referral to an ENT specialist to confirm the diagnosis and exclude other causes. Patients should also consider the risks of certain activities, such as driving or operating heavy machinery, during severe symptoms. With proper management, patients with Ménière’s disease can improve their quality of life and reduce the impact of their symptoms.

A 67-year-old man contacts emergency services due to experiencing central crushing chest pain that spreads to his left arm and jaw. Upon arrival at the emergency department, his heart rate is recorded at 50/min. An ECG is conducted, revealing ST elevation and bradycardia with a 1st-degree heart block. Based on the provided information, which leads are expected to display the ST elevation?
Your Answer:
Correct Answer: II, III and aVF
Explanation:An ST-elevated myocardial infarction affecting the inferior leads (II, III, aVF) can cause arrhythmias due to the involvement of the right coronary artery, which supplies blood to the AV node. This is evidenced by the patient’s presentation with 1st-degree heart block following the MI.
Anteroseptal changes in V1-V4 indicate involvement of the left anterior descending artery. Inferior changes in II, III, and aVF suggest the right coronary artery is affected. Anterolateral changes in V1-6, I, and aVL indicate the proximal left anterior descending artery is involved. Lateral changes in I, aVL, and possibly V5-6 suggest the left circumflex artery is affected. Posterior changes in V1-3 may indicate a posterior infarction, which is confirmed by ST elevation and Q waves in posterior leads (V7-9). This type of infarction is usually caused by the left circumflex artery, but can also be caused by the right coronary artery. Reciprocal changes of STEMI are typically seen as horizontal ST depression, tall and broad R waves, upright T waves, and a dominant R wave in V2. It is important to note that a new left bundle branch block (LBBB) may indicate acute coronary syndrome.
Overall, understanding the correlation between ECG changes and coronary artery territories is crucial in diagnosing acute coronary syndrome. By identifying the specific changes in the ECG, medical professionals can determine which artery is affected and provide appropriate treatment. Additionally, recognizing the reciprocal changes of STEMI and the significance of a new LBBB can aid in making an accurate diagnosis.

A 61-year-old man presents to his GP with increasing mild confusion over the past 2 weeks. His husband has also noticed a decline in his mental state. The patient's medical history includes a road traffic accident 8 weeks ago, where he sustained a head injury but was discharged from the emergency department with no significant injuries. He denies any current symptoms of headache, nausea, or changes in vision. On examination, there are no focal neurological deficits, and both ocular and mental state exams are unremarkable. What is the most likely cause of this man's presentation?
Your Answer:
Correct Answer: Subdural haematoma
Explanation:Understanding Subdural Haemorrhage
A subdural haemorrhage is a condition where blood collects deep to the dural layer of the meninges. This collection of blood is not within the brain substance and is referred to as an ‘extra-axial’ or ‘extrinsic’ lesion. Subdural haematomas can be classified based on their age, which includes acute, subacute, and chronic. Although they occur within the same anatomical compartment, acute and chronic subdurals have significant differences in terms of their mechanisms, associated clinical features, and management.
An acute subdural haematoma is a collection of fresh blood within the subdural space and is commonly caused by high-impact trauma. This type of haematoma is associated with high-impact injuries, and there is often other underlying brain injuries. Symptoms and presentation vary depending on the size of the compressive acute subdural haematoma and the associated injuries. CT imaging is the first-line investigation, and surgical options include monitoring of intracranial pressure and decompressive craniectomy.
On the other hand, a chronic subdural haematoma is a collection of blood within the subdural space that has been present for weeks to months. Elderly and alcoholic patients are particularly at risk of subdural haematomas since they have brain atrophy and therefore fragile or taut bridging veins. Infants also have fragile bridging veins and can rupture in shaken baby syndrome. If the chronic subdural is an incidental finding or if it is small in size with no associated neurological deficit, it can be managed conservatively. However, if the patient is confused, has an associated neurological deficit, or has severe imaging findings, surgical decompression with burr holes is required.
