Question 131: A 39-year-old woman presents with 12 weeks of persistent fatigue, poor sleep quality, and widespread pain. She describes the pain as constant, affecting neck, back, arms and legs with no clear pattern. Examination reveals multiple tender points but no joint swelling or inflammation. Blood tests including FBC, CRP, TSH, and vitamin D are all normal. What pain assessment tool is most appropriate for monitoring her condition?
- A. Fibromyalgia Impact Questionnaire (FIQ) (Correct Answer)
- B. Visual Analogue Scale (VAS) for pain intensity
- C. Brief Pain Inventory (BPI)
- D. McGill Pain Questionnaire
- E. DN4 neuropathic pain questionnaire
Explanation: ***Fibromyalgia Impact Questionnaire (FIQ)***- The **Fibromyalgia Impact Questionnaire (FIQ)** is the gold-standard tool specifically designed to assess and monitor the multidimensional impact of **fibromyalgia**, including physical function, fatigue, and sleep quality.- Given the patient's symptoms of **widespread pain**, fatigue, and normal inflammatory markers, the FIQ is most appropriate for evaluating **treatment response** and disease severity.*Visual Analogue Scale (VAS) for pain intensity*- Measuring **pain intensity** alone via a VAS is insufficient for fibromyalgia, as it fails to capture associated symptoms like **fatigue** and **cognitive dysfunction**.- While useful for quick assessments, it lacks the **specificity** required for the comprehensive management of complex chronic pain syndromes.*Brief Pain Inventory (BPI)*- The **Brief Pain Inventory** is primarily used to assess how pain interferes with daily activities in patients with **chronic cancer** or non-cancer pain.- While it assesses **pain interference**, it is not as specialized as the FIQ for tracking the specific **biopsychosocial clusters** found in fibromyalgia.*McGill Pain Questionnaire*- This tool focuses on the **sensory and affective qualities** of pain (e.g., throbbing, stabbing) rather than the overall functional impact of a specific syndrome.- It is less effective than the FIQ for monitoring the **holistic progression** of fibromyalgia symptoms over time.*DN4 neuropathic pain questionnaire*- The **DN4** is a screening tool specifically designed to identify **neuropathic pain** components, such as burning or tingling, which require different management.- Fibromyalgia is categorized as **nociplastic pain** rather than pure neuropathic pain, making the DN4 inappropriate for monitoring its overall impact.
Question 132: A 63-year-old woman presents with 4 months of bilateral shoulder and hip girdle pain with marked morning stiffness lasting over 2 hours. She describes difficulty rising from chairs and combing her hair. She reports fatigue and 4kg weight loss. ESR is 82 mm/hr, CRP 56 mg/L. Creatine kinase is normal. What is the most appropriate initial treatment?
- A. Prednisolone 15mg daily (Correct Answer)
- B. Naproxen 500mg twice daily
- C. Methotrexate 15mg weekly
- D. Physiotherapy and exercise programme
- E. Referral to rheumatology before starting treatment
Explanation: ***Prednisolone 15mg daily*** - The patient's symptoms, including bilateral shoulder and hip girdle pain, marked morning stiffness lasting over 2 hours, and elevated **ESR/CRP** with normal **creatine kinase**, are classic for **Polymyalgia Rheumatica (PMR)**.- **Low-dose oral corticosteroids** like **prednisolone** are the most appropriate initial treatment for PMR, leading to rapid and dramatic symptom improvement. *Naproxen 500mg twice daily* - **NSAIDs** like naproxen may offer some symptomatic pain relief but do not address the underlying systemic inflammation of **PMR**.- They are insufficient to control the disease's activity, which is characterized by significantly elevated **inflammatory markers**. *Methotrexate 15mg weekly* - **Methotrexate** is a **steroid-sparing agent** typically reserved for patients with recurrent relapses, those requiring prolonged high-dose steroids, or those unable to taper steroids.- It is not indicated as a first-line therapy for the initial management of uncomplicated **PMR**. *Physiotherapy and exercise programme* - While **physiotherapy** and exercise are beneficial for maintaining mobility and function, they are **adjunctive therapies** and cannot treat the systemic inflammation of **PMR**.- This condition requires potent anti-inflammatory medication to control symptoms and reduce inflammatory markers. *Referral to rheumatology before starting treatment* - For a classic presentation of **PMR** as described, initial corticosteroid treatment should ideally be commenced in **primary care** to provide rapid relief and prevent unnecessary suffering.- Referral to **rheumatology** is usually reserved for atypical cases, diagnostic uncertainty, or treatment failure.
Question 133: According to current UK guidelines, which of the following features is essential to define a classic fever of unknown origin (FUO) in an ambulatory patient?
- A. Temperature >38.0°C on multiple occasions for at least 3 days with no diagnosis after appropriate initial investigations
- B. Temperature >38.3°C on several occasions for at least 3 weeks with no diagnosis after one week of investigation (Correct Answer)
- C. Temperature >37.8°C for at least 2 weeks with negative blood cultures and chest X-ray
- D. Unexplained fever for at least 4 weeks in a patient without immunocompromise
- E. Persistent fever with negative investigations after 48 hours of inpatient assessment
Explanation: ***Temperature >38.3°C on several occasions for at least 3 weeks with no diagnosis after one week of investigation*** - The classic definition of **Fever of Unknown Origin (FUO)** requires a documented temperature of **>38.3°C** (101°F) to ensure the fever is clinically significant and not just a mild elevation. - The criteria also mandate a duration of at least **3 weeks** and a failure to reach a diagnosis after **one week** of intensive outpatient or inpatient investigation, indicating a thorough workup has been completed. *Temperature >38.0°C on multiple occasions for at least 3 days with no diagnosis after appropriate initial investigations* - While **38.0°C** is often the threshold for a general fever, the **Petersdorf and Beeson** criteria, widely adopted for classic FUO, specifically require **>38.3°C**. - A **3-day** duration is insufficient to differentiate FUO from common, self-limiting viral illnesses which typically resolve within a week. *Temperature >37.8°C for at least 2 weeks with negative blood cultures and chest X-ray* - The temperature threshold of **>37.8°C** is too low and does not meet the established diagnostic criteria for **classic FUO**. - Although negative **blood cultures** and **chest X-ray** are standard initial steps, the definition specifically requires failure of a broader and more comprehensive **one-week** diagnostic workup, not just these initial tests. *Unexplained fever for at least 4 weeks in a patient without immunocompromise* - While classic FUO occurs in non-immunocompromised patients, the standard time requirement is **3 weeks**, not **4 weeks**. - This description lacks the specific **temperature threshold** (>38.3°C) necessary to satisfy clinical guidelines for FUO. *Persistent fever with negative investigations after 48 hours of inpatient assessment* - A **48-hour** assessment period is diagnostic for **nosocomial FUO** in some contexts, but classic FUO requires a much longer period of **3 weeks** of symptoms. - The criteria for an **ambulatory patient** specifically involve at least **three outpatient visits** or one week of thorough investigation to qualify as FUO, which is a more prolonged process than 48 hours.
Question 134: A 47-year-old woman presents with 6 months of progressive fatigue, 7kg weight loss, and polyuria. She reports increased thirst and recurrent oral thrush. Random blood glucose is 16.2 mmol/L. HbA1c is 78 mmol/mol (9.3%). BMI is 22 kg/m². She has no family history of diabetes. What is the most important next step in management?
- A. Start metformin and arrange follow-up in 3 months
- B. Check anti-GAD and islet cell antibodies (Correct Answer)
- C. Start metformin and SGLT2 inhibitor
- D. Refer to secondary care for insulin therapy
- E. Arrange pancreatic imaging with CT
Explanation: ***Check anti-GAD and islet cell antibodies*** - The patient's presentation with **progressive fatigue**, **significant weight loss (7kg)**, **polyuria**, **increased thirst**, **recurrent oral thrush**, and a **normal BMI (22 kg/m²)**, despite high blood glucose and HbA1c, strongly suggests an **insulin-deficient state**. - Checking **anti-GAD** and **islet cell antibodies** is crucial to diagnose **Latent Autoimmune Diabetes in Adults (LADA)** or **Type 1 Diabetes**, which requires different management strategies, often involving early insulin initiation, compared to Type 2 Diabetes. *Start metformin and arrange follow-up in 3 months* - **Metformin** is primarily for **Type 2 Diabetes** (insulin resistance) and is unlikely to be sufficient for a patient with features suggestive of **severe insulin deficiency** and acute symptoms. - A 3-month follow-up is too delayed given the patient's significant symptoms and high HbA1c, as they are at risk of developing **Diabetic Ketoacidosis (DKA)**. *Start metformin and SGLT2 inhibitor* - This combination is typically used for **Type 2 Diabetes**. In patients with suspected **Type 1 Diabetes** or **LADA**, SGLT2 inhibitors can significantly increase the risk of **euglycemic diabetic ketoacidosis**, even with normal or mildly elevated blood glucose levels. - The patient's **weight loss** and **normal BMI** point away from the typical pathophysiology of Type 2 Diabetes (insulin resistance), making these drugs potentially inappropriate and risky without further diagnostic clarification. *Refer to secondary care for insulin therapy* - While the patient will likely require **insulin therapy** given the probable diagnosis of Type 1 Diabetes or LADA, the most important immediate step is to confirm the diagnosis through **autoantibody testing**. - Referral for insulin therapy without prior diagnostic clarity might lead to an incomplete assessment or delay in initiating appropriate, specific treatment, though insulin will be necessary if confirmed. *Arrange pancreatic imaging with CT* - While new-onset diabetes and weight loss can rarely be a presentation of **pancreatic cancer**, the clinical picture of **recurrent thrush**, **polyuria**, and **thirst** is more characteristic of primary hyperglycemia and an underlying **autoimmune process**. - **Pancreatic imaging** is usually considered when other
Question 135: A 41-year-old man presents with 10 weeks of fatigue, drenching night sweats, and 8kg weight loss. He mentions persistent generalized itching, particularly after hot baths. Examination reveals non-tender rubbery cervical lymphadenopathy. Blood tests show Hb 110 g/L, WCC 11.2 × 10⁹/L, ESR 65 mm/hr. What is the most likely diagnosis?
- A. Hodgkin lymphoma (Correct Answer)
- B. Non-Hodgkin lymphoma
- C. Chronic lymphocytic leukaemia
- D. Infectious mononucleosis
- E. Tuberculosis
Explanation: ***Hodgkin lymphoma***- The presence of **B symptoms** (weight loss, drenching night sweats) and **rubbery, non-tender cervical lymphadenopathy** is classic for Hodgkin lymphoma.- **Aquagenic pruritus** (itching specifically after a hot bath) is a highly characteristic feature that helps distinguish it from other causes of lymphadenopathy.*Non-Hodgkin lymphoma*- While it presents with B symptoms and lymphadenopathy, **aquagenic pruritus** is significantly less common than in Hodgkin lymphoma.- It more frequently involves **extranodal sites** and typically presents in an older age group compared to the classical bimodal distribution of Hodgkin's.*Chronic lymphocytic leukaemia*- This typically presents in **older adults** (median age >70) and is often an incidental finding on blood counts showing significant **lymphocytosis**.- Although it causes lymphadenopathy, it does not typically present with the specific symptom of **itching after hot baths**.*Infectious mononucleosis*- Usually presents with an **acute history** (1-2 weeks) of sore throat, fever, and tender lymphadenopathy rather than a 10-week chronic course.- It is associated with **atypical lymphocytes** on a blood film and a positive **Monospot test**, not significant weight loss and high ESR.*Tuberculosis*- Can cause chronic weight loss, night sweats, and cervical lymphadenopathy (scrofula), but the nodes eventually become **matted and fluctuant** (cold abscess).- It lacks the association with **alcohol-induced pain** or **aquagenic pruritus**, and would typically show evidence of pulmonary involvement on imaging.
Question 136: A 56-year-old woman presents with 8 weeks of progressive fatigue and unintentional weight loss of 9kg. She describes early satiety and vague epigastric discomfort. Past medical history includes pernicious anaemia. Examination reveals a palpable epigastric mass and left supraclavicular lymphadenopathy. What is the single most appropriate initial investigation?
- A. Oesophagogastroduodenoscopy with biopsy (Correct Answer)
- B. CT chest, abdomen and pelvis
- C. CA 19-9 and CEA tumour markers
- D. Barium swallow
- E. Abdominal ultrasound
Explanation: ***Oesophagogastroduodenoscopy with biopsy*** - The patient exhibits classic **red-flag symptoms** for gastric cancer, including **weight loss**, **early satiety**, an **epigastric mass**, and a **Virchow's node** (left supraclavicular lymphadenopathy). - **Pernicious anaemia** is a known risk factor for gastric malignancy; **OGD** is the gold standard for direct visualization and obtaining a definitive **histological diagnosis**. *CT chest, abdomen and pelvis* - This is a critical step for **staging** the disease and identifying **metastases** once the diagnosis is suspected. - However, it is not the **initial investigation** of choice as it cannot provide the essential **tissue biopsy** needed for diagnosis. *CA 19-9 and CEA tumour markers* - These markers lack the **sensitivity** and **specificity** required to be used as primary diagnostic or screening tools for gastric cancer. - They are more clinically useful for **monitoring response to treatment** or detecting **recurrence** in known patients. *Barium swallow* - While it can identify **structural abnormalities** or filling defects, it has been largely superseded by endoscopy in modern practice. - It does not allow for **biopsy** and may miss early-stage or small **gastric lesions**. *Abdominal ultrasound* - Ultrasound is insensitive for evaluating hollow viscera like the stomach due to **overlying bowel gas**. - It might detect liver metastases or a large mass, but it cannot confirm the **pathological type** of the tumor.
Question 137: A 32-year-old woman presents with a 3-month history of intermittent fever, night sweats, and 5kg weight loss. She recently returned from volunteer work in Southeast Asia. Examination reveals cervical and axillary lymphadenopathy. Chest X-ray shows bilateral hilar lymphadenopathy. Mantoux test is 18mm induration. What is the most appropriate next investigation?
- A. Sputum microscopy and culture for acid-fast bacilli
- B. CT chest, abdomen and pelvis
- C. Lymph node biopsy for histology and culture (Correct Answer)
- D. Interferon-gamma release assay (IGRA)
- E. Bronchoscopy with bronchoalveolar lavage
Explanation: ***Lymph node biopsy for histology and culture*** - This patient presents with **B symptoms**, recent travel to a **high-risk area**, generalized **lymphadenopathy**, and a strongly positive **Mantoux test**, highly suggestive of **extrapulmonary tuberculosis**. - An **excisional lymph node biopsy** is the gold standard for diagnosis, providing tissue for **histology** (to identify **caseating granulomas**) and **microbiology culture** (for definitive identification of *Mycobacterium tuberculosis* and **drug sensitivity testing**). *Sputum microscopy and culture for acid-fast bacilli* - While crucial for **pulmonary tuberculosis**, sputum samples are often negative in cases of **extrapulmonary TB**, especially when there are no significant respiratory symptoms like cough. - Relying solely on sputum would likely delay the diagnosis of **tuberculous lymphadenitis** when accessible peripheral nodes are available for biopsy. *CT chest, abdomen and pelvis* - A CT scan can help assess the **extent of lymphadenopathy** and other organ involvement, but it is an imaging modality that cannot provide a **definitive tissue diagnosis** or confirm the etiology of the disease. - It is useful for staging but not the most appropriate **initial diagnostic investigation** to confirm active TB. *Interferon-gamma release assay (IGRA)* - IGRA, similar to the **Mantoux test**, indicates exposure to **Mycobacterium tuberculosis** but **cannot differentiate** between **latent TB infection** and **active TB disease**. - As the Mantoux test is already strongly positive (18mm), an IGRA would not provide additional information to guide the diagnosis of **active disease** in this symptomatic patient. *Bronchoscopy with bronchoalveolar lavage* - This is an **invasive procedure** primarily used to obtain samples from the **lower respiratory tract** in cases of suspected pulmonary disease, especially when sputum is negative or unobtainable. - It is less appropriate as the immediate next step when readily **accessible peripheral lymph nodes** are available for a less invasive and more direct diagnostic biopsy for **tuberculous adenitis**.
Question 138: A 38-year-old woman presents with a 9-week history of progressive fatigue, weight loss of 6kg, and persistent abdominal pain. She mentions increased thirst and urinary frequency. She appears tanned despite no recent sun exposure. Examination reveals postural hypotension (BP 118/76 mmHg lying, 92/58 mmHg standing) and hyperpigmentation of palmar creases and buccal mucosa. Blood tests show: Na⁺ 128 mmol/L, K⁺ 5.6 mmol/L, glucose 3.8 mmol/L, urea 8.2 mmol/L. What is the most appropriate next investigation to confirm the diagnosis?
- A. Short synacthen test (Correct Answer)
- B. 9 am cortisol and ACTH
- C. CT abdomen and pelvis
- D. Plasma metanephrines
- E. Thyroid function tests with thyroid antibodies
Explanation: ***Short synacthen test***- The **short synacthen test (SST)** is the gold standard confirmatory investigation for **primary adrenal insufficiency (Addison's disease)** as it evaluates the adrenal gland's ability to produce cortisol in response to synthetic ACTH.- An inadequate or absent rise in **cortisol** after synacthen administration (typically below a certain threshold like >450-550 nmol/L) confirms the diagnosis.*9 am cortisol and ACTH*- While low **9 am cortisol** and elevated **ACTH** levels are highly suggestive of primary adrenal insufficiency, a single basal measurement can be influenced by stress and diurnal rhythm, lacking the definitive power of a dynamic test.- These tests provide initial evidence but are not as conclusive as a stimulation test like the **SST** for confirming adrenal insufficiency.*CT abdomen and pelvis*- This imaging modality is primarily used to identify the **underlying etiology** of adrenal insufficiency, such as **adrenal atrophy**, **hemorrhage**, **tuberculosis**, or **metastatic disease**.- It is typically performed after the biochemical diagnosis of **adrenal insufficiency** has been established and is not the initial test to confirm adrenal function.*Plasma metanephrines*- This test screens for **pheochromocytoma**, an adrenal tumor that secretes catecholamines and usually presents with **paroxysmal hypertension**, tachycardia, and diaphoresis.- The patient's presentation with **postural hypotension**, **hyperpigmentation**, **hyponatremia**, and **hyperkalemia** is inconsistent with a catecholamine-secreting tumor.*Thyroid function tests with thyroid antibodies*- While **Addison's disease** can be part of **Autoimmune Polyendocrine Syndrome (APS)**, thyroid dysfunction does not explain the classic findings of **hyperpigmentation**, **postural hypotension**, and the specific electrolyte abnormalities (low sodium, high potassium).- The clinical picture strongly points to a primary adrenal issue, making thyroid testing a secondary diagnostic step.
Question 139: A 71-year-old man presents with an 8-week history of fevers up to 38.4°C occurring every 2-3 days, progressive fatigue, and 5kg weight loss. He has a history of aortic valve replacement 4 years ago. Examination reveals temperature 37.9°C, a new early diastolic murmur, and splinter haemorrhages in two fingernails. Blood tests show: Hb 104 g/L, WCC 12.8 × 10⁹/L, CRP 95 mg/L, creatinine 145 μmol/L (baseline 88). Three sets of blood cultures taken over 24 hours are negative. What is the most appropriate next step?
- A. Start empirical antibiotic therapy for culture-negative endocarditis
- B. Arrange urgent transoesophageal echocardiography (Correct Answer)
- C. Repeat blood cultures and extend incubation time for fastidious organisms
- D. Arrange CT-PET scan to identify source of infection
- E. Refer to cardiothoracic surgery for urgent assessment
Explanation: ***Arrange urgent transoesophageal echocardiography***- **Transoesophageal echocardiography (TOE)** is the investigation of choice for **prosthetic valve endocarditis (PVE)**, as it has superior sensitivity (90-100%) compared to transthoracic echocardiography for detecting vegetations and perivalvular abscesses.- The patient presents with **Duke criteria** including a **predisposing heart condition** (aortic valve replacement), fever, a **new diastolic murmur**, and **splinter haemorrhages**, making urgent imaging essential to confirm the diagnosis and assess its extent.*Start empirical antibiotic therapy for culture-negative endocarditis*- Initiating **empirical antibiotics** should ideally follow a definitive diagnosis or at least comprehensive imaging to avoid obscuring potential culture results or delaying the identification of specific pathogens.- Without prior visualization of vegetations or complications via **echocardiography**, committing to long-term intensive therapy might be premature and could delay necessary surgical evaluation.*Repeat blood cultures and extend incubation time for fastidious organisms*- While repeating blood cultures and extending incubation time is part of the workup for **culture-negative endocarditis**, it should not delay the more urgent **echocardiographic assessment** required to identify valvular damage or vegetations.- Many fastidious organisms like HACEK group are often detected within standard incubation, and specific organisms (e.g., **Bartonella, Coxiella**) require serological testing or PCR rather than simply extended culture time.*Arrange CT-PET scan to identify source of infection*- **18F-FDG PET/CT** is a valuable tool for diagnosing **PVE** when echocardiography is inconclusive, or to identify extracardiac sites of infection or emboli.- However, **transoesophageal echocardiography (TOE)** remains the gold standard for the initial, detailed assessment of **valvular vegetations**, abscesses, and assessment of valve function directly on the prosthetic valve.*Refer to cardiothoracic surgery for urgent assessment*- **Surgical consultation** is indicated in endocarditis, particularly with complications like heart failure, severe valve dysfunction, or large vegetations, which need to be characterized.- However, a definitive assessment of the extent of valvular involvement and complications through **echocardiography** is a prerequisite before a meaningful surgical referral can be made.
Question 140: A 43-year-old woman presents with a 12-week history of fatigue, poor concentration, and unrefreshing sleep. She describes widespread pain affecting multiple body sites that has persisted despite taking regular paracetamol and ibuprofen. She reports headaches, irritable bowel symptoms, and feeling 'fuzzy-headed'. Examination reveals multiple tender points but no joint swelling, muscle weakness, or abnormal neurological signs. Blood tests including FBC, TFTs, CRP, ESR, vitamin D, and B12 are all normal. What is the most appropriate management approach?
- A. Refer to rheumatology for specialist assessment
- B. Start low-dose amitriptyline and arrange graded exercise programme (Correct Answer)
- C. Request MRI brain and spine to exclude neurological pathology
- D. Start prednisolone trial for possible inflammatory condition
- E. Arrange referral to chronic fatigue syndrome service
Explanation: ***Start low-dose amitriptyline and arrange graded exercise programme***- The patient's presentation with chronic **widespread pain**, **fatigue**, **unrefreshing sleep**, **cognitive dysfunction** (fibro-fog), and multiple **tender points** alongside normal inflammatory markers (ESR, CRP) is highly characteristic of **fibromyalgia**.- **Low-dose amitriptyline** is a common first-line pharmacological treatment for fibromyalgia to improve sleep and reduce pain, while a **graded exercise program** is a key non-pharmacological intervention, emphasizing a **multidisciplinary approach** to management.*Refer to rheumatology for specialist assessment*- Fibromyalgia is primarily a **clinical diagnosis**, and with typical features and normal basic investigations, initial management can often be handled in **primary care**.- Referral to rheumatology is generally considered for diagnostic uncertainty, atypical presentations, or when **first-line treatments** in primary care have been unsuccessful.*Request MRI brain and spine to exclude neurological pathology*- The patient has a completely normal **neurological examination** (no muscle weakness, abnormal signs) and no **red flag symptoms** such as focal neurological deficits or cauda equina signs, making advanced imaging like MRI unnecessary.- Symptoms like **'fuzzy-headedness'** are typical for the **cognitive dysfunction** associated with fibromyalgia, often termed 'fibro-fog', rather than indicating a structural neurological lesion.*Start prednisolone trial for possible inflammatory condition*- The patient's normal **ESR** and **CRP** effectively rule out an active **inflammatory condition** that would typically respond to corticosteroids, such as polymyalgia rheumatica or inflammatory arthritis.- **Corticosteroids** like prednisolone are not indicated for fibromyalgia, as they do not address the underlying pathophysiology and carry a significant risk of **adverse effects**.*Arrange referral to chronic fatigue syndrome service*- While there is symptom overlap with **Chronic Fatigue Syndrome (CFS/ME)**, the predominant and widespread **musculoskeletal pain** with distinct **tender points** strongly points towards **fibromyalgia**.- The initial management strategies for both conditions share common ground (e.g., activity pacing), but the primary focus in this case based on the symptom profile is on managing the chronic pain syndrome characteristic of fibromyalgia.
