A 26-year-old construction worker visits his GP complaining of elbow swelling that has been present for three weeks. He reports that it started gradually and has no known triggers. The area is painful and warm to the touch, but he has no swelling in other parts of his body and feels generally well. The patient has a history of well-managed rheumatoid arthritis and is taking methotrexate, and has no other medical conditions. During the examination, the doctor detects a tender, soft, fluctuant mass on the back of the patient's elbow. Based on these findings, what is the most probable diagnosis?
Your Answer: Olecranon bursitis
Explanation:Olecranon bursitis is a condition that occurs when the olecranon bursa, a fluid-filled sac located over the olecranon process at the proximal end of the ulna, becomes inflamed. This bursa serves to reduce friction between the elbow joint and the surrounding soft tissues. Inflammation can be caused by trauma, infection, or systemic conditions such as rheumatoid arthritis or gout. It is also commonly known as student’s elbow due to the repetitive mild trauma of leaning on a desk using the elbows. The condition can be categorized as septic or non-septic depending on whether an infection is present.
The condition is more common in men and typically presents between the ages of 30 and 60. Causes of olecranon bursitis include repetitive trauma, direct trauma, infection, gout, rheumatoid arthritis, and idiopathic reasons. Patients with non-septic olecranon bursitis typically present with swelling over the olecranon process, while some may also experience tenderness and erythema over the bursa. Patients with septic bursitis are more likely to have pain and fever.
Signs of olecranon bursitis include swelling over the posterior aspect of the elbow, tenderness on palpation of the swollen area, redness and warmth of the overlying skin, fever, skin abrasion overlying the bursa, effusions in other joints if associated with rheumatoid arthritis, and tophi if associated with gout. Movement at the elbow joint should be painless until the swollen bursa is compressed in full flexion.
Investigations are not always needed if a clinical diagnosis can be made and there is no concern about septic arthritis. However, if septic bursitis is suspected, aspiration of bursal fluid for microscopy and culture is essential. Purulent fluid suggests infection, while straw-colored bursal fluid favors a non-infective cause.

A 32-year-old primigravid woman at twelve weeks gestation visits her obstetrician for a routine booking appointment. She has sickle cell anaemia. She has sickle cell anaemia. Her partner’s sickle cell status is Hb AS. Her haemoglobin is 92 g/l (normal range: 115–155 g/l).
What is the likelihood of her baby having sickle cell disease?Your Answer: 1 in 3
Correct Answer: 1 in 2
Explanation:Probability of Inheriting Sickle Cell Disease
Sickle cell anaemia is an autosomal recessive condition that affects the haemoglobin in red blood cells. If one parent has sickle cell anaemia (HbSS) and the other is a carrier (HbAS), the baby has a 1 in 2 chance of inheriting the condition. The baby will inherit the HbS allele from the mother and either the HbA or HbS allele from the father, resulting in possible genotypes of HbAS, HbSS, HbAS, or HbSS. This gives the baby a 1 in 2 chance of having sickle cell disease and a 1 in 2 chance of being a carrier.
If both parents are carriers (HbAS), the baby has a 1 in 4 chance of inheriting sickle cell disease. If one parent has the condition and the other is a carrier, there is a 1 in 2 chance the child will inherit the condition. In the case of a heterozygous father and a mother with sickle cell disease, there is a 1 in 3 chance of the baby having the condition. Finally, if both parents are carriers and the baby inherits one HbS allele from each parent, there is a 1 in 8 chance of the baby having sickle cell disease and a 3 in 8 chance of being a carrier. Understanding the probabilities of inheriting sickle cell disease can help individuals make informed decisions about family planning and genetic testing.

A 25-year-old patient visits their doctor with suspected tonsillitis recurrence. They report having had tonsillitis three times in the past year and currently have a fever and cough. During the examination, the doctor notes tender cervical lymphadenopathy and exudative tonsils. The patient is prescribed phenoxymethylpenicillin. On day 5 of treatment, blood tests are taken and reveal the following results:
Hb 150 g/L Male: (135-180) Female: (115 - 160)
Platelets 390 * 109/L (150 - 400)
WBC 10.2 * 109/L (4.0 - 11.0)
Neuts 0.8 * 109/L (2.0 - 7.0)
Lymphs 9.2 * 109/L (1.0 - 3.5)
Mono 0.2 * 109/L (0.2 - 0.8)
Eosin 0.0 * 109/L (0.0 - 0.4)
What could be the possible reasons for the abnormalities in these blood results?Your Answer: Underlying diagnosis of glandular fever
Explanation:The presence of lymphocytosis and neutropenia in a person who has been treated for recurrent tonsillitis may indicate an underlying condition. Glandular fever, caused by the Epstein-Barr virus, is a common cause of recurrent tonsillitis in young people and can result in an increase in activated T and B lymphocytes, leading to lymphocytosis. The virus may also cause neutropenia, although the exact cause is not fully understood. A peritonsillar abscess, tonsillitis unresponsive to treatment, and treatment with phenoxymethylpenicillin are unlikely to cause significant abnormalities in the full blood count. While lymphoma may explain the lymphocytosis, it would not account for the neutropenia and is less likely than an underlying glandular fever infection.
Understanding Neutropaenia: Causes and Severity
Neutropaenia is a medical condition characterized by low neutrophil counts, which is below 1.5 * 109. A normal neutrophil count ranges from 2.0 to 7.5 * 109. It is crucial to recognize this condition as it increases the risk of severe infections. Neutropaenia can be classified into three categories based on its severity: mild (1.0 – 1.5 * 109), moderate (0.5 – 1.0 * 109), and severe (< 0.5 * 109). There are several causes of neutropaenia, including viral infections such as HIV, Epstein-Barr virus, and hepatitis. Certain drugs like cytotoxics, carbimazole, and clozapine can also cause neutropaenia. Benign ethnic neutropaenia is common in people of black African and Afro-Caribbean ethnicity, but it requires no treatment. Haematological malignancies like myelodysplastic malignancies and aplastic anemia, as well as rheumatological conditions like systemic lupus erythematosus and rheumatoid arthritis, can also cause neutropaenia. Severe sepsis and haemodialysis are other potential causes of neutropaenia. In summary, neutropaenia is a medical condition that can increase the risk of severe infections. It is important to recognize its severity and underlying causes to provide appropriate treatment and management.

A 72-year-old retired teacher visits the doctor with a painless gradual loss of vision. She reports difficulty reading as the words on the page are becoming harder to see. Additionally, she notices that straight lines in her artwork are appearing distorted, which is confirmed by Amsler grid testing. What is the probable diagnosis?
Your Answer: Dry age-related macular degeneration
Explanation:The most likely diagnosis for this patient’s gradual central loss of vision and difficulty reading is dry age-related macular degeneration. This subtype accounts for the majority of cases of macular degeneration and typically presents with a gradual loss of vision. Glaucoma and retinal detachment are unlikely diagnoses as they present with different symptoms such as peripheral vision loss and sudden vision loss with flashes and floaters, respectively.
Age-related macular degeneration (ARMD) is a common cause of blindness in the UK, characterized by the degeneration of the central retina (macula) and the formation of drusen. It is more prevalent in females and is strongly associated with advancing age, smoking, family history, and conditions that increase the risk of ischaemic cardiovascular disease. ARMD can be classified into two forms: dry and wet. Dry ARMD is more common and is characterized by drusen, while wet ARMD is characterized by choroidal neovascularisation and carries a worse prognosis. Clinical features of ARMD include subacute onset of visual loss, difficulties in dark adaptation, and visual disturbances such as photopsia and glare.
To diagnose ARMD, slit-lamp microscopy and color fundus photography are used to identify any pigmentary, exudative, or haemorrhagic changes affecting the retina. Fluorescein angiography and indocyanine green angiography may also be used to visualize changes in the choroidal circulation. Treatment for dry ARMD involves a combination of zinc with anti-oxidant vitamins A, C, and E, which has been shown to reduce disease progression by around one third. For wet ARMD, anti-VEGF agents such as ranibizumab, bevacizumab, and pegaptanib are used to limit disease progression and stabilize or reverse visual loss. Laser photocoagulation may also be used to slow progression, but anti-VEGF therapies are usually preferred due to the risk of acute visual loss after treatment.
In summary, ARMD is a common cause of blindness in the UK that is strongly associated with advancing age, smoking, and family history. It can be classified into dry and wet forms, with wet ARMD carrying a worse prognosis. Diagnosis involves the use of various imaging techniques, and treatment options include a combination of zinc and anti-oxidant vitamins for dry ARMD and anti-VEGF agents or laser photocoagulation for wet ARMD.

In the differential diagnosis of cognitive decline, which of the following is the single most appropriate statement?
Your Answer: A multi-infarct aetiology is more common than the Alzheimer disease type
Correct Answer: In Creutzfeldt-Jakob disease an EEG may be characteristic
Explanation:Misconceptions about Dementia: Debunking Common Myths
Dementia is a complex and often misunderstood condition. Here are some common misconceptions about dementia that need to be debunked:
1. In Creutzfeldt-Jakob disease an EEG may be characteristic: An EEG is abnormal in approximately 90% of cases of Creutzfeldt-Jakob disease, showing characteristic changes (i.e. periodic sharp wave complexes).
2. A multi-infarct aetiology is more common than the Alzheimer disease type: Multi-infarct dementia is the second most common type of dementia in people aged over 65 years.
3. A CT scan will reliably distinguish between Alzheimer disease and multi-infarct dementia: The diagnosis of both AD and multi-infarct dementia remains essentially a clinical one (and can only be definitively confirmed at autopsy).
4. In Alzheimer disease a gait disorder is seen at an early stage: Gait disturbances are usually a late sign of AD.
5. Visual hallucinations are typical of Alzheimer’s disease: Visual hallucinations, often very vivid and colourful, are typical of dementia with Lewy bodies (DLB) and Parkinson’s disease dementia (PDD), not of AD.

A 21-year-old soccer player comes to you with complaints of shoulder and lower back pain. He reports that his back has been getting stiffer over the past few months and has worsened. During the examination, you find out that he is also experiencing enthesitis of the Achilles tendon. You suspect a particular diagnosis and want to confirm it. What antigen's presence would confirm the diagnosis?
Your Answer: HLA-B27
Explanation:Ankylosing spondylitis is a type of spondyloarthropathy that is associated with HLA-B27. It is more commonly seen in young males, with a sex ratio of 3:1, and typically presents with lower back pain and stiffness that develops gradually. The stiffness is usually worse in the morning and improves with exercise, while pain at night may improve upon getting up. Clinical examination may reveal reduced lateral and forward flexion, as well as reduced chest expansion. Other features associated with ankylosing spondylitis include apical fibrosis, anterior uveitis, aortic regurgitation, Achilles tendonitis, AV node block, amyloidosis, cauda equina syndrome, and peripheral arthritis (more common in females).

A 65-year-old woman presents to the Emergency Department with a cough, fever, diarrhoea and myalgia. The cough is non-productive and has been getting gradually worse since she returned from holiday in Italy one week ago. Her daughter is concerned because over the past 24 hours she has become more drowsy and febrile. She is normally fit and well but drinks around 15 units of alcohol per week.
On examination, pulse is 80/min, blood pressure 110/70 mmHg, oxygen saturations are 95% on room air and temperature is 38.2ºC. Bilateral coarse crackles are heard in the chest.
Initial blood tests show the following:
Hb 13.8 g/dl
Platelets 300 * 109/l
WBC 14.5 * 109/l
Na+ 132 mmol/l
K+ 4.1 mmol/l

A chest x-ray shows patchy consolidation in the right lower zone with an associated pleural effusion.
What is the most likely causative organism?Your Answer: Streptococcus pneumoniae
Correct Answer: Legionella pneumophila
Explanation:Legionella is often characterized by symptoms resembling the flu, such as a dry cough, confusion, and a slower than normal heart rate. Additionally, hyponatremia may be detected through blood tests. A history of recent travel abroad and the presence of pleural effusion are also indicative of Legionella.
Legionnaire’s Disease: Symptoms, Diagnosis, and Management
Legionnaire’s disease is a type of pneumonia caused by the Legionella pneumophilia bacterium, which is commonly found in water tanks. It is not transmitted from person to person. Symptoms of the disease include flu-like symptoms such as fever, dry cough, confusion, and lymphopaenia. Other features include relative bradycardia, hyponatraemia, and deranged liver function tests. Pleural effusion is seen in around 30% of patients.
Diagnosis of Legionnaire’s disease can be done through a urinary antigen test. Treatment involves the use of erythromycin or clarithromycin. Chest x-ray features of the disease are non-specific but may include patchy consolidation with a mid-to-lower zone predominance.
Compared to Mycoplasma pneumonia, Legionnaire’s disease has distinct differences in symptoms and diagnostic methods. It is important to be aware of the potential for Legionnaire’s disease in cases where water tanks or air-conditioning systems may be involved, as early diagnosis and treatment can lead to better outcomes.

A 58-year-old woman complains of developing urinary incontinence. She reports no urinary urgency or pain, but experiences leakage of urine when she coughs or laughs. What is the best initial approach to manage this condition?
Your Answer: Pelvic floor muscle training
Explanation:The initial treatment for urinary incontinence differs depending on the type. For urge incontinence, bladder retraining is the recommended first-line approach. On the other hand, for stress incontinence, pelvic floor muscle training is the preferred initial treatment.
Understanding Urinary Incontinence: Causes, Classification, and Management
Urinary incontinence (UI) is a common condition that affects around 4-5% of the population, with elderly females being more susceptible. Several risk factors contribute to UI, including advancing age, previous pregnancy and childbirth, high body mass index, hysterectomy, and family history. UI can be classified into different types, such as overactive bladder (OAB)/urge incontinence, stress incontinence, mixed incontinence, overflow incontinence, and functional incontinence.
Initial investigation of UI involves completing bladder diaries for at least three days, vaginal examination, urine dipstick and culture, and urodynamic studies. Management of UI depends on the predominant type of incontinence. For urge incontinence, bladder retraining and bladder stabilizing drugs such as antimuscarinics are recommended. For stress incontinence, pelvic floor muscle training and surgical procedures such as retropubic mid-urethral tape procedures may be offered. Duloxetine, a combined noradrenaline and serotonin reuptake inhibitor, may also be used as an alternative to surgery.
In summary, understanding the causes, classification, and management of UI is crucial in providing appropriate care for patients. Early diagnosis and intervention can significantly improve the quality of life for those affected by this condition.

A 4-year-old child is rushed to the emergency department due to severe breathing difficulties caused by croup. The child was given oral dexamethasone by the GP earlier in the day. Upon examination, the child's oxygen saturation is at 89% on room air and there is noticeable intercostal recession. What emergency treatment should be administered to the child?
Your Answer: Oxygen + nebulised adrenaline
Explanation:Understanding Croup: A Respiratory Infection in Infants and Toddlers
Croup is a type of upper respiratory tract infection that commonly affects infants and toddlers. It is characterized by a barking cough, fever, and coryzal symptoms, and is caused by a combination of laryngeal oedema and secretions. Parainfluenza viruses are the most common cause of croup. The condition typically peaks between 6 months and 3 years of age, and is more prevalent during the autumn season.
The severity of croup can be graded based on the presence of symptoms such as stridor, cough, and respiratory distress. Mild cases may only have occasional barking cough and no audible stridor at rest, while severe cases may have frequent barking cough, prominent inspiratory stridor at rest, and marked sternal wall retractions. Children with moderate or severe croup, those under 6 months of age, or those with known upper airway abnormalities should be admitted to the hospital.
Diagnosis of croup is usually made based on clinical presentation, but a chest x-ray may show subglottic narrowing, commonly referred to as the steeple sign. Treatment for croup typically involves a single dose of oral dexamethasone or prednisolone, regardless of severity. In emergency situations, high-flow oxygen and nebulized adrenaline may be necessary.
Understanding croup is important for parents and healthcare providers alike, as prompt recognition and treatment can help prevent complications and improve outcomes for affected children.

A 42-year-old woman presents to her General Practitioner with polyuria, weight loss and tiredness for six months. Full blood count, urea and electrolytes (U&Es), liver function tests, thyroid function test and calcium are all normal. Glycosylated haemoglobin (HbA1c) is 48 mmol/mol and repeat sample is 50 mmol/mol. On examination, her body mass index is 35 kg/m2, she is normotensive and urinalysis is normal.
Which of the following investigations should be arranged urgently?
Select ONE investigation from the list below.Your Answer: Computed tomography (CT) abdomen
Explanation:Diagnostic Tests for a Patient with Suspected Type II Diabetes Mellitus
Computed Tomography (CT) Abdomen:
A CT abdomen is recommended for any patient over the age of 60 with weight loss combined with a new onset of diabetes or abdominal or back pain, nausea, vomiting or change in bowel habit. This is because new-onset type II diabetes can be a presenting feature of pancreatic cancer in patients over the age of 60, especially those who have also experienced weight loss.Pancreatic Autoantibodies:
Pancreatic autoantibodies include anti-glutamic acid decarboxylase, insulin autoantibodies and islet-cell antibodies, the presence of which would support a diagnosis of type I diabetes. These tests are usually carried out in secondary care for atypical presentations such as suspected type II diabetes in a child or a non-overweight person.Glucose Tolerance Test:
Glucose tolerance test has a limited role in diagnosing type II diabetes now that HbA1c is an accepted diagnostic investigation. It is still used routinely to investigate pregnant women at risk of gestational diabetes.Short Synacthen Test:
A short synacthen test is used to diagnose adrenal insufficiency. The history and investigation results do not suggest this as a likely diagnosis, so this test would not be indicated.Ultrasound of the Urinary Tract:
Ultrasound is not indicated unless a structural problem is suspected. Although this man is experiencing polyuria, his urinalysis and PSA are both normal, which makes a urological cause for his symptoms less likely than the newly diagnosed diabetes. Diabetes can cause renal impairment, but this should be monitored with annual urine albumin : creatinine measurement and regular U&Es blood test. -

A 57-year-old woman, who is known to have rheumatoid arthritis, complains that she has had recurrent haemoptysis for over five years. She has never smoked and only takes a non-steroidal anti-inflammatory agent. According to her, she coughs up phlegm every day and at times this contains streaks of fresh blood. She has no known respiratory disease, but tends to get frequent chest infections that are relieved by a course of antibiotics.
Which of the following is the most likely diagnosis?Your Answer: Bronchiectasis
Explanation:Understanding Bronchiectasis: Causes, Symptoms, and Treatment
Bronchiectasis is a condition characterized by permanent and irreversible dilatations of the bronchial walls. It can be caused by various factors, including cystic fibrosis, immune system deficiencies, lung infections, foreign body aspiration, and smoking. Common symptoms of bronchiectasis include high sputum production, recurrent chest infections, and haemoptysis. A high-resolution computed tomography (HR-CT) scan of the lungs is usually used to diagnose bronchiectasis. Treatment involves a multidisciplinary approach, including chest physiotherapy, patient education, antibiotic treatment, and bronchodilators. While treatment of the underlying cause may be necessary, it does not provide reversal of the existing bronchiectasis. Other conditions, such as atypical pneumonia, lung cancer, tuberculosis, and pulmonary embolism, may have similar symptoms but require different diagnoses and treatments.

A 55-year-old man presents to the General Practice with a 4-week history of pain in his left hand and forearm. The pain is concentrated around the thumb and index finger and is worse at night. There is no history of trauma. Shaking his hand seems to provide some relief. The likely diagnosis conclusion is carpal tunnel syndrome (CTS).
Which of the following would suggest an alternative diagnosis?Your Answer: Wasting of thenar eminence
Correct Answer: Wasting of the hypothenar eminence
Explanation:Understanding Carpal Tunnel Syndrome: Symptoms and Examination Findings
Carpal tunnel syndrome (CTS) is a condition caused by compression of the median nerve in the carpal tunnel. One of the symptoms of CTS is the wasting of the thenar eminence, which is innervated by the median nerve. It is important to note that the hypothenar eminence, which is innervated by the ulnar nerve, is not affected by CTS.
During examination, weakness of thumb abduction (abductor pollicis brevis) is a common finding in CTS. Tapping along the problematic nerve causes paraesthesia, which is known as Tinel’s sign. Flexion of the wrist also causes symptoms, which is known as Phalen’s sign.
Treatment for CTS may include a corticosteroid injection, wrist splints at night, and surgical decompression through flexor retinaculum division.
Overall, understanding the symptoms and examination findings of CTS can help with early diagnosis and appropriate treatment.

A healthy toddler is 18 months old and was born in the breech position. The toddler's mother is concerned about developmental dysplasia of the hip (DDH), as she has heard that this can be associated with breech delivery.
Which of the following is the most appropriate investigation for this toddler?Your Answer: Ultrasound scan of the hips only if they are found to be unstable at the 6-week baby check
Correct Answer: Ultrasound scan of the hips before six weeks of age
Explanation:An ultrasound scan of the hips is recommended for all babies born in the breech position after 36 weeks of pregnancy, even if they are not born in the breech position. It is also necessary for babies born before 36 weeks in the breech position or those with a family history of hip problems in early life. This is to detect developmental dysplasia of the hip (DDH) early, which can be treated with a Pavlik harness before six months of age. Surgery may be required if non-operative treatment is not successful. An ultrasound scan should be performed before six weeks of age to ensure early diagnosis and treatment. If a baby is found to have an unstable hip joint during their newborn examination, they should have an ultrasound of the hip before two weeks of age. X-rays are not recommended for detecting DDH in infants, and ultrasound is the preferred imaging modality.

Which of the following is not a known side effect of the combined oral contraceptive pill?
Your Answer: Increased risk of cervical cancer
Correct Answer: Increased risk of ovarian cancer
Explanation:While the combined oral contraceptive pill may increase the risk of breast and cervical cancer, it has been found to provide protection against ovarian and endometrial cancer. In fact, studies have shown that the pill can actually decrease the risk of ovarian cancer.
Pros and Cons of the Combined Oral Contraceptive Pill
The combined oral contraceptive pill is a highly effective method of birth control with a failure rate of less than 1 per 100 woman years. It does not interfere with sexual activity and its contraceptive effects are reversible upon stopping. Additionally, it can make periods regular, lighter, and less painful, and may reduce the risk of ovarian, endometrial, and colorectal cancer. It may also protect against pelvic inflammatory disease, ovarian cysts, benign breast disease, and acne vulgaris.
However, there are also some disadvantages to the combined oral contraceptive pill. One of the main issues is that people may forget to take it, which can reduce its effectiveness. It also offers no protection against sexually transmitted infections. There is an increased risk of venous thromboembolic disease, breast and cervical cancer, stroke, and ischaemic heart disease, especially in smokers. Temporary side-effects such as headache, nausea, and breast tenderness may also be experienced.
It is important to weigh the pros and cons of the combined oral contraceptive pill before deciding if it is the right method of birth control for you. While some users report weight gain while taking the pill, a Cochrane review did not support a causal relationship. Overall, the combined oral contraceptive pill can be an effective and convenient method of birth control, but it is important to discuss any concerns or potential risks with a healthcare provider.

A 62-year-old man has been referred due to a tremor and bradykinesia, leading to a diagnosis of Parkinson's disease. These symptoms are now interfering with his work as an accountant and overall quality of life. What initial treatment is he likely to receive?
Your Answer: Levodopa
Explanation:Patients with newly diagnosed Parkinson’s who experience motor symptoms that negatively impact their quality of life should be provided with levodopa.
Management of Parkinson’s Disease: Medications and Considerations
Parkinson’s disease is a complex condition that requires specialized expertise in movement disorders for diagnosis and management. However, all healthcare professionals should be familiar with the medications used to treat Parkinson’s disease due to its prevalence. The National Institute for Health and Care Excellence (NICE) published guidelines in 2017 to aid in the management of Parkinson’s disease.
For first-line treatment, levodopa is recommended if motor symptoms are affecting the patient’s quality of life. If motor symptoms are not affecting the patient’s quality of life, dopamine agonists (non-ergot derived), levodopa, or monoamine oxidase B (MAO-B) inhibitors may be used. NICE provides tables to aid in decision-making regarding the use of these medications, taking into account their effects on motor symptoms, activities of daily living, motor complications, and adverse events.
If a patient continues to have symptoms despite optimal levodopa treatment or has developed dyskinesia, NICE recommends the addition of a dopamine agonist, MAO-B inhibitor, or catechol-O-methyl transferase (COMT) inhibitor as an adjunct. Other considerations in Parkinson’s disease management include the risk of acute akinesia or neuroleptic malignant syndrome if medication is not taken or absorbed, the potential for impulse control disorders with dopaminergic therapy, and the need to adjust medication if excessive daytime sleepiness or orthostatic hypotension develops.
Specific medications used in Parkinson’s disease management include levodopa, dopamine receptor agonists, MAO-B inhibitors, amantadine, COMT inhibitors, and antimuscarinics. Each medication has its own set of benefits and potential adverse effects, which should be carefully considered when selecting a treatment plan. Overall, the management of Parkinson’s disease requires a comprehensive approach that takes into account the individual needs and circumstances of each patient.

You are working in a GP surgery and you meet a 25-year-old newly qualified healthcare assistant who has come in to see you as she would like to know more about the BCG vaccination and whether she needs to have it. You advise her that she will need the BCG as she is at risk of occupational exposure. She would also like to know more about who needs to have the BCG vaccination.
Who needs a BCG vaccination assuming they have not had one before?Your Answer: A 27-year-old pregnant woman who has starting working in a care home for disabled children
Correct Answer: A 22-year-old man who has started work as a prison officer
Explanation:Children born in areas with a high prevalence of tuberculosis (TB) or with parents/grandparents from such areas, as well as individuals under the age of 35 at high risk of occupational exposure to TB, are administered the BCG vaccine. However, there is no evidence to support the effectiveness of the BCG vaccine for individuals over the age of 35, and therefore it is not administered to them.
The BCG Vaccine: Who Should Get It and How It’s Administered
The Bacille Calmette-Guérin (BCG) vaccine is a vaccine that provides limited protection against tuberculosis (TB). In the UK, it is given to high-risk infants and certain groups of people who are at risk of contracting TB. The vaccine contains live attenuated Mycobacterium bovis and also offers limited protection against leprosy.
The Greenbook provides guidelines on who should receive the BCG vaccine. It is recommended for all infants living in areas of the UK where the annual incidence of TB is 40/100,000 or greater, as well as infants with a parent or grandparent who was born in a country with a high incidence of TB. The vaccine is also recommended for previously unvaccinated tuberculin-negative contacts of cases of respiratory TB, new entrants under 16 years of age who were born in or have lived for a prolonged period in a high-risk country, healthcare workers, prison staff, staff of care homes for the elderly, and those who work with homeless people.
Before receiving the BCG vaccine, any person being considered must first be given a tuberculin skin test, except for children under 6 years old who have had no contact with tuberculosis. The vaccine is given intradermally, normally to the lateral aspect of the left upper arm. It can be given at the same time as other live vaccines, but if not administered simultaneously, there should be a 4-week interval.
There are some contraindications for the BCG vaccine, including previous BCG vaccination, a past history of tuberculosis, HIV, pregnancy, and a positive tuberculin test (Heaf or Mantoux). It is not given to anyone over the age of 35, as there is no evidence that it works for people of this age group.

A 26-year-old woman comes to the clinic 10 days after giving birth. She reports a continuous pink vaginal discharge with a foul odor. During the examination, her pulse is 90 / min, temperature is 38.2ºC, and she experiences diffuse suprapubic tenderness. The uterus feels tender on vaginal examination, but her breasts appear normal. The urine dipstick shows blood ++. What is the best course of action for management?
Your Answer: Admit to hospital
Explanation:Understanding Puerperal Pyrexia
Puerperal pyrexia is a condition that occurs when a woman experiences a fever of more than 38ºC within the first 14 days after giving birth. The most common cause of this condition is endometritis, which is an infection of the lining of the uterus. Other causes include urinary tract infections, wound infections, mastitis, and venous thromboembolism.
If a woman is suspected of having endometritis, it is important to seek medical attention immediately. Treatment typically involves intravenous antibiotics such as clindamycin and gentamicin until the patient is afebrile for more than 24 hours. It is important to note that puerperal pyrexia can be a serious condition and should not be ignored.

An 82-year-old man is admitted under the medical take with acute chest pain. An MRI of the chest with contrast is requested. His blood tests show acute kidney injury (AKI).
Which of the following would mitigate the risk of worsening AKI when using contrast?Your Answer: IV fluids before and after a CT scan
Explanation:Preventing Contrast-Induced Nephropathy: Strategies and Considerations
Contrast-induced nephropathy (CIN) is a common complication of IV contrast administration, particularly in patients with pre-existing renal impairment. CIN is characterized by a decline in renal function within 48-72 hours of contrast exposure. To prevent CIN, strategies that focus on maintaining intravascular volume expansion are crucial.
Intravenous (IV) saline 0.9% is preferred over 0.45% saline as it enhances intravascular volume expansion and prevents renin-angiotensin activation. Oral fluids are beneficial but not as effective as IV hydration. Volume expansion should begin 6 hours before the procedure and continue for 6-24 hours post-procedure, with post-procedure hydration being more important than pre-procedure hydration.
Diuretics alone are not recommended, but a recent meta-analysis suggests that furosemide with matched hydration may reduce the incidence of CIN in high-risk patients. Fluid restriction is not recommended, and oral fluids should be encouraged.
Dialysis is required in less than 1% of patients with CIN, with a slightly higher incidence in patients with underlying renal impairment and those undergoing primary percutaneous coronary intervention for myocardial infarction. N-Acetylcysteine (NAC) supplementation has been associated with a significant decrease in CIN risk and blood creatinine levels, but it does not reduce mortality or the need for dialysis.
In conclusion, preventing CIN requires a multifaceted approach that includes maintaining intravascular volume expansion, avoiding fluid restriction, and considering NAC supplementation in high-risk patients.

A 30-year-old man presents with multiple, ring-shaped, papular rashes on his legs. He has recently noticed a red, raised intra-oral lesion.
What is the most likely diagnosis?Your Answer: Erythema multiforme
Correct Answer: Lichen planus
Explanation:Skin Conditions: Lichen Planus, Erythema Multiforme, Psoriasis, Ringworm, and Tinea Versicolor
Lichen Planus: A skin condition that affects cutaneous and mucosal surfaces, characterised by flat-topped plaques and papules with a purple hue and white striae. It can be treated with topical steroids and immunomodulators.
Erythema Multiforme: A skin condition characterised by targetoid lesions with a central depression, usually starting on the acral extensor surfaces and progressing to involve the trunk and back. It can be caused by medications, infections, or underlying conditions.
Psoriasis: An autoimmune chronic skin condition presenting with erythematous plaques and greyscale on the extensor surfaces of extremities. It is not associated with intra-oral mucosal lesions.
Ringworm: A fungal skin infection characterised by erythematous, scaly patches on the skin surface of the trunk, back, and extremities. It can lead to the formation of pustules or vesicles.
Tinea Versicolor: A fungal skin infection characterised by pale or dark, copper-coloured patches on the arms, neck, and trunk. It does not involve mucosal surfaces.

A 50-year-old woman presents to you with her husband. Her husband complains of frequently waking up in the middle of the night and experiencing difficulty in breathing. She also notes that he feels excessively tired during the day and often dozes off while reading the newspaper. You suspect moderate sleep apnoea and decide to refer him for further evaluation. The patient is curious about the treatment options available. What is the primary treatment for moderate sleep apnoea?
Your Answer: Continuous positive airway pressure (CPAP)
Explanation:Understanding Obstructive Sleep Apnoea/Hypopnoea Syndrome
Obstructive sleep apnoea/hypopnoea syndrome (OSAHS) is a condition where the upper airway becomes partially or completely blocked during sleep, leading to interrupted breathing and reduced oxygen levels in the body. There are several predisposing factors for OSAHS, including obesity, macroglossia, large tonsils, and Marfan’s syndrome. The condition is often characterized by excessive snoring and periods of apnoea, which can be reported by the patient’s partner.
OSAHS can have several consequences, including daytime somnolence, compensated respiratory acidosis, and hypertension. To assess sleepiness, healthcare professionals may use tools such as the Epworth Sleepiness Scale or the Multiple Sleep Latency Test. Diagnostic tests for OSAHS include sleep studies, ranging from monitoring pulse oximetry to full polysomnography.
Management of OSAHS typically involves weight loss and continuous positive airway pressure (CPAP) as the first line of treatment for moderate or severe cases. Intra-oral devices may be used if CPAP is not tolerated or for patients with mild OSAHS. It is important to inform the DVLA if OSAHS is causing excessive daytime sleepiness. While there is limited evidence to support the use of pharmacological agents, healthcare professionals may consider them in certain cases.
Overall, understanding OSAHS and its management is crucial for improving the quality of life for patients with this condition.

In which of the following respiratory diseases is clubbing not a feature?
Your Answer: Bronchitis
Explanation:The Significance of Finger Clubbing in Respiratory and Non-Respiratory Diseases
Finger clubbing, the loss of the natural angle between the nail and the nailbed, is a significant clinical sign that can indicate underlying respiratory and non-respiratory diseases. Suppurative lung diseases such as long-standing bronchiectasis, acute lung abscesses, and empyema are commonly associated with finger clubbing. However, uncomplicated bronchitis and chronic obstructive pulmonary disease (COPD) do not typically cause clubbing, and patients with COPD who develop clubbing should be promptly investigated for other causes, particularly lung cancer.
Finger clubbing is also commonly found in fibrosing alveolitis (idiopathic pulmonary fibrosis), asbestosis, and malignant diseases such as bronchial carcinoma and mesothelioma. In cases where finger clubbing is associated with hypertrophic pulmonary osteoarthropathy, a painful osteitis of the distal ends of the long bones of the lower arms and legs, it is designated grade IV.
Overall, finger clubbing is an important clinical sign that should prompt further investigation to identify underlying respiratory and non-respiratory diseases.

A 28-year-old male patient complains of a painful rash on his forehead that has been present for one day. The patient has no significant medical history. Upon examination, a vesicular rash is observed on the right side in the distribution of the ophthalmic nerve. There is no discharge or pus, and no ocular involvement is present. What is the recommended treatment for this condition?
Your Answer: Oral acyclovir for 7-10 days
Explanation:In the case of herpes zoster ophthalmicus, topical antiviral treatment is not recommended. The first line of treatment is oral acyclovir, which should be initiated promptly and continued for 7-10 days. If there are any indications of ocular involvement, the patient should be referred to an ophthalmologist immediately. While steroids can be administered concurrently, they do not decrease the likelihood of post-herpetic neuralgia. Topical mupirocin is not an appropriate treatment option.
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 45-year-old man is diagnosed with end-stage renal disease. What is the most frequent complication that may arise when considering long-term peritoneal dialysis for this patient?
Your Answer: Carpal tunnel syndrome
Explanation:Chronic dialysis patients may experience median nerve compression, which can be caused by oedema or vascular insufficiency related to a dialysis shunt or fistula. Amyloid disease, which can infiltrate the synovium within the carpal tunnel, may also contribute to nerve compression in patients with renal failure. Anaemia is a common complication of chronic kidney disease, resulting from decreased renal synthesis of erythropoietin. This type of anaemia is normochromic normocytic and can lead to the development of new-onset heart failure. However, the use of erythropoiesis-stimulating agents has reduced the incidence of congestive heart failure due to anaemia. Squamous cell skin cancer is a type of skin cancer that is strongly associated with high total exposure to ultraviolet radiation from the sun. Individuals who have received solid organ transplants and are taking chronic immunosuppressive medication are at a significantly increased risk of developing this type of cancer, particularly squamous cell carcinoma. There is no known increased risk of gastrointestinal malignancy in patients on long-term haemodialysis. Immunosuppression, such as in the case of kidney transplant recipients, is associated with an increased risk of non-Hodgkin’s lymphoma.

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 new father is curious as to when his toddler will be receiving her vaccines. He is particularly interested in the six-in-one vaccine which he has heard about from some friends at playgroup. When is the six-in-one vaccine given to toddlers?
Your Answer: 8, 12, and 16 weeks
Explanation:Childhood Vaccination Schedule in the UK
In the UK, childhood vaccinations are an important part of ensuring the health and wellbeing of children. Here is a breakdown of the vaccination schedule:
8, 12, and 16 weeks: The 6-in-1 vaccine is given as a single injection to protect against diphtheria, hepatitis B, Haemophilus influenza B, polio, tetanus, and pertussis. This vaccine is given at eight, 12, and 16 weeks old.
One year: At one year, children receive the MMR vaccine, Hib/Men C vaccine, and third dose of the meningitis B and pneumococcal vaccines.
8, 12, and 16 months: There are three doses given, however at eight, 12, and 16 weeks of age, not months.
24 months: From 2-9 years old, children will receive the annual flu vaccine via nasal spray.
It is important to follow the vaccination schedule to ensure that children are protected against serious illnesses. Talk to your healthcare provider for more information.

A 32-year-old man comes to the clinic with a maculopapular rash and mouth ulcers. He had a painless penile ulcer two months ago. What is the most probable causative organism for his symptoms?
Your Answer: Treponema pallidum
Explanation:The symptoms exhibited by this individual suggest the presence of secondary syphilis.
Understanding Syphilis: Symptoms and Stages
Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum. The infection progresses through three stages: primary, secondary, and tertiary. The incubation period can range from 9 to 90 days.
During the primary stage, a painless ulcer called a chancre appears at the site of sexual contact. Local lymph nodes may also become swollen, but this symptom may not be visible in women if the lesion is on the cervix.
The secondary stage occurs 6 to 10 weeks after the primary infection and is characterized by systemic symptoms such as fevers and lymphadenopathy. A rash may appear on the trunk, palms, and soles, along with buccal ulcers and painless warty lesions on the genitalia.
In the tertiary stage, granulomatous lesions called gummas may develop on the skin and bones, and there may be an ascending aortic aneurysm. Other symptoms include general paralysis of the insane, tabes dorsalis, and Argyll-Robertson pupil.
Congenital syphilis can also occur if a pregnant woman is infected. Symptoms include blunted upper incisor teeth, linear scars at the angle of the mouth, keratitis, saber shins, saddle nose, and deafness.
Understanding the symptoms and stages of syphilis is important for early detection and treatment. It is a treatable infection, but if left untreated, it can lead to serious complications.

A 26-year-old male patient complains of severe pain during defecation for the last two weeks. He has also noticed occasional blood on the toilet paper while wiping. During the examination, a tear is observed on the posterior midline of the anal verge. Which of the following treatment options should not be suggested?
Your Answer: Application of lubricant prior to defecation
Correct Answer: Topical steroids
Explanation:Studies have demonstrated that topical steroids are not very effective in the treatment of anal fissures.
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 35-year-old man presents to the Emergency Department with rapid onset abdominal pain, which is worse on lying. He feels nauseous and is vomiting.
On examination, he is tachycardic and pyrexial at 38.1°C. His abdomen is tender with marked guarding. There is bruising around his umbilicus.
The patient reports drinking six cans of strong lager per day. He also smokes two packets of cigarettes a day. He says he was last in hospital two years ago when he was vomiting blood. He cannot remember what treatment he was given. He has no other medical history of note. He does not take any medications regularly.
What is the most likely cause for the man’s presentation and signs?Your Answer: Pancreatitis with retroperitoneal haemorrhage
Explanation:Differential diagnosis for a man with abdominal pain and retroperitoneal haemorrhage
The man in question presents with classic symptoms of pancreatitis, including abdominal pain that radiates to the back and worsens on lying down, as well as nausea. However, his periumbilical bruising suggests retroperitoneal haemorrhage, which can also manifest as flank bruising. This condition may be related to his alcohol consumption, which increases the risk of both pancreatitis and coagulopathy.
While bleeding oesophageal varices are another potential consequence of alcohol abuse, they would not explain the absence of haematemesis or malanea on this admission, nor the retroperitoneal haemorrhage. Similarly, hepatic cirrhosis and consequent coagulopathy could contribute to bleeding but would not account for the sudden onset of abdominal pain or the lack of ecchymosis elsewhere. A pancreatic abscess, which can develop as a complication of pancreatitis, would typically present with a swinging fever and a longer history of symptoms.
Finally, a ruptured duodenal ulcer could cause upper gastrointestinal bleeding, but there is no evidence of this in the current case. The absence of reflux also makes this diagnosis less likely. Overall, the differential diagnosis for this patient includes pancreatitis with retroperitoneal haemorrhage, which may be related to alcohol use, and other conditions that do not fully fit the clinical picture.

A 25-year-old man presents to the GP with a swelling in his scrotum. He is feeling well otherwise. Upon examination, there is a soft swelling on the right side of the scrotum that is painless and illuminates brightly with a pen torch. The swelling is localized to the scrotum, and the rest of the scrotum can be palpated above the mass. The testicle is palpable with no apparent mass. The patient is particularly concerned about the possibility of having testicular cancer.
What is the most probable diagnosis?Your Answer: Hydrocele
Explanation:Scrotal swelling caused by an accumulation of fluid in the tunica vaginalis is known as a hydrocele. This condition can be identified by its ability to transilluminate brightly with a pen torch and is confined to the scrotum. While epididymo-orchitis can also cause unilateral swelling, it is typically tender and accompanied by systemic symptoms. Testicular cancer may lead to a hydrocele, but if the testis is palpable and normal, it is less likely to be the cause of the swelling. In cases where the testis is not palpable, patients should be referred for a testicular ultrasound.
Common Scrotal Problems and Their Features
Epididymal cysts, hydroceles, and varicoceles are the most common scrotal problems seen in primary care. Epididymal cysts are usually found posterior to the testicle and are separate from the body of the testicle. They may be associated with conditions such as polycystic kidney disease, cystic fibrosis, and von Hippel-Lindau syndrome. Diagnosis is confirmed by ultrasound, and management is usually supportive, although surgical removal or sclerotherapy may be attempted for larger or symptomatic cysts.
Hydroceles, on the other hand, describe the accumulation of fluid within the tunica vaginalis. They may be communicating or non-communicating, and may develop secondary to conditions such as epididymo-orchitis, testicular torsion, or testicular tumors. Hydroceles are usually soft, non-tender swellings of the hemi-scrotum that transilluminate with a pen torch. Diagnosis may be clinical, but ultrasound is required if there is any doubt about the diagnosis or if the underlying testis cannot be palpated. Management depends on the severity of the presentation, with infantile hydroceles generally repaired if they do not resolve spontaneously by the age of 1-2 years.
Varicoceles, on the other hand, are abnormal enlargements of the testicular veins that are usually asymptomatic but may be associated with subfertility. They are much more common on the left side and are classically described as a bag of worms. Diagnosis is confirmed by ultrasound with Doppler studies, and management is usually conservative, although surgery may be required if the patient is troubled by pain. There is ongoing debate regarding the effectiveness of surgery to treat infertility.

A 30-year-old woman is brought to the emergency department with difficulty breathing. Her pulmonary function tests show a peak expiratory flow rate that is 60% below the normal range for her age and height.
What is the most likely diagnosis?Your Answer: Kyphoscoliosis
Correct Answer: Asthma
Explanation:Understanding PEFR and Its Role in Diagnosing Asthma
Peak expiratory flow rate (PEFR) is a valuable tool in both the diagnosis and management of asthma. It is measured by a maximal forced expiration through a peak-flow meter and correlates well with forced expiratory volume in one second (FEV1), providing an estimate of airway calibre. Patients with asthma can monitor their PEFR at home to track disease control. A PEFR <80% of predicted is a strong indicator of obstructive airway disease, such as asthma. However, it’s important to note that PEFR is not affected by restrictive defects, such as those caused by kyphoscoliosis. Bronchial carcinoma itself does not cause airflow limitation, but a co-morbid obstructive lung disease, such as asthma or COPD, could produce abnormal PEFR readings. Bronchiectasis can cause an obstructive pattern on spirometry, but it would not typically cause a reduction in PEFR. Whooping cough, despite causing inflammation of the airways, would not typically result in the markedly reduced PEFR readings seen in asthma. In conclusion, understanding PEFR and its role in diagnosing asthma is crucial for both patients and healthcare providers. By monitoring PEFR at home and seeking medical attention when necessary, individuals with asthma can better manage their condition and improve their quality of life.
