BMJ Cases Flashcards
A 30-year-old woman presents with 4-month history of recurrent oral and genital ulcers. She gets the oral ulcers every other week, >5 at a time, and they resolve on their own in 7 to 10 days. They cause discomfort and occur in the inner lips and cheeks and on her tongue.
The genital ulcers are fewer in number and not always painful. She has also noticed acne on her legs and on her back, but not on her face, although she never had any facial acne as a teenager. She has also had 2 episodes of painful, red, round lesions on her legs. These resolved without treatment after 1 week.
Bechets
A 35-year-old woman has a history of 3 consecutive pregnancy losses before 12 weeks of pregnancy. She had no other known complications during the pregnancies. Further testing reveals a lupus anticoagulant, which is still present on repeat testing 12 weeks later. Physical examination is normal.
antiphospholipid syndrome
A 79-year-old man presents with dyspnoea on exertion for 1 year and lower extremity oedema. As part of a cardiac work-up, the echo shows concentric left ventricular hypertrophy. Cardiac catheterisation shows normal coronary arteries and he is referred for further evaluation of non-cardiac dyspnoea.
amyloidosis
A 28-year-old man presents with a 2-month history of eye pain and blurring of vision that has been getting worse over the last several weeks. Both of his eyes are involved. He also complains of recurrent oral and genital ulcers that have been bothering him for the last 5 months. He has had facial acne for some time, but now is getting acne on his back, upper arms, and legs.
behcet’s
A 20-year-old man presents to his primary care physician with low back pain and stiffness that has persisted for more than 3 months. There is no history of obvious injury but he is a very avid sportsman. His back symptoms are worse when he awakes in the morning, and the stiffness lasts more than 1 hour. His back symptoms improve with exercise.
He has a desk job and finds that sitting for long periods of time exacerbates his symptoms. He has to get up regularly and move around. His back symptoms also wake him in the second half of the night, after which he can find it difficult to get comfortable. He normally takes an anti-inflammatory drug during the day, and finds his stiffness is worse when he misses a dose. He has had 2 bouts of iritis in the past.
ankylosing spondylitis
A 42-year-old man is referred because of central retinal vein thrombosis. Medical history is uneventful; in particular, he has no known risk factors for venous or arterial thromboembolic disease. Screening for antiphospholipid antibodies reveals moderately elevated anticardiolipin antibody levels on 2 occasions, 12 weeks apart.
antiphospholipid syndrome
Case history #2
A 62-year-old man is referred for management of atypical multiple myeloma. He has a mild anaemia of 120 g/L (12 g/dL), a urinary protein loss of 2.2 g/day with a urinary immunofixation showing free lambda light chains. However, the bone marrow shows only 5% plasma cells and does not fulfil criteria for multiple myeloma.
amyloidosis
A 50-year-old woman presents with numbness and tingling in her hands. The symptoms are worse in her right (dominant) hand and with activities such as holding a book or a steering wheel, or brushing her hair. The discomfort in her hands frequently wakes her at night, and she has to shake or hang her hand out of her bed for relief.
carpal tunnel syndrome
A 54-year-old man complains of severe pain and swelling in his right first toe that developed overnight. He is limping because of the pain and states that this is the most severe pain he has ever had (‘even covering my foot with the bed sheet hurts’). He has had no previous episodes. His only medication is hydrochlorothiazide for hypertension. He drinks 2 to 3 beers a day. On examination, he is obese. There is swelling, erythema, warmth, and tenderness of the right first toe. There is also tenderness and warmth with mild swelling over the mid foot.
gout
A 38-year-old woman sees her physician with 4 years of widespread body pain. The pain began after a motor vehicle accident and was initially limited to her neck. Gradually, the pain has spread and she now complains of hurting all over, all the time. She does not have any joint swelling or systemic symptoms.
She does not sleep well and has fatigue. She has irritable bowel syndrome but is otherwise healthy. Physical examination reveals a well-appearing woman with normal musculoskeletal examination, except for the presence of tenderness in 12 out of 18 fibromyalgia tender points. Routine laboratory testing is normal.
fibromyalgia
A 21-year-old male student presents with a 4-week history of a painful, hot, and swollen left knee, low back pain with bilateral buttock pain, and left heel pain. He denies trauma and states the symptoms began acutely. He denies any fever or any other significant arthralgias.
Further review of symptoms indicates the patient was treated for a chlamydia infection after he developed dysuria approximately 8 weeks ago (he was treated with a single dose of azithromycin). He admits to unprotected sexual intercourse with a new partner 2 days before the onset of his dysuria. In addition to pain and swelling, the patient reports that he has developed morning stiffness in the left knee and low back that last more than 1 hour.
He continues to have episodes of dysuria. The findings of physical examination are significant for a large effusion of the left knee with warmth. Range of motion is slightly diminished. There is tenderness to palpation of the left heel at the site of the Achilles’ insertion. Laboratory findings are significant for an ESR of 35 mm/hour, and both FBC and uric acid level are within normal limits. He is HLA-B27 positive, rheumatoid factor negative, and ANA negative.
The synovial fluid analysis is negative for crystals, with a total nucleated cell count of 22,000 cells/microlitre (65% neutrophils). A urethral swab was positive by PCR for Chlamydia trachomatis 9 weeks ago at initial presentation of dysuria. There was no evidence of gram-negative diplococci on Gram stain.
reactive arthiritis
An 85-year-old man presents with several days of swelling and severe pain in both hands limiting his ability to use his walking frame. He has a history of gout but has not experienced these symptoms before. On examination, he has a temperature of 37.8°C (100.1°F). There is diffuse warmth, mild erythema, and pitting oedema over the dorsum of both hands. There is tenderness and limited hand grip bilaterally. There are multiple nodules around several of the proximal interphalangeal and distal interphalangeal joints, and effusion and tenderness in his left olecranon bursa with palpable nodules.
gout
A 72-year-old white woman presents with partial vision loss in the right eye. She reports bitemporal headache for several weeks, accompanied by pain and stiffness in the neck and shoulders. Review of systems is positive for low-grade fever, fatigue, and weight loss. On physical examination, there is tenderness of the scalp over the temporal areas and thickening of the temporal arteries.
Fundoscopic examination reveals pallor of the right optic disc. Bilateral shoulder range of motion is limited and painful. There is no synovitis or tenderness of the peripheral joints. There are no carotid or subclavian bruits, and the blood pressure is normal and equal in both arms. The remainder of the examination is unremarkable.
temporal arteritis
A 60-year-old woman presents complaining of bilateral knee pain on most days of the past few months. The pain was gradual in onset. The pain is over the anterior aspect of the knee and gets worse with walking and going up and down stairs. She complains of stiffness in the morning that lasts for a few minutes and a buckling sensation at times in the right knee. On examination, there is a small effusion, diffuse crepitus, and limited flexion of both knees. Joint tenderness is more prominent over the medial joint line bilaterally. She has a steady but slow gait, slightly favouring the right side.
osteoarthiritis
A 58-year-old woman presents with a 2-week history of fatigue, anorexia, fevers, and bilateral pain and stiffness in the shoulder and hip girdles. These symptoms are worse at night. Upon awakening in the morning, she feels as if she has a bad flu. She reports difficulty getting out of bed in the morning due to stiffness. Her wrists and finger joints are also painful and swollen.
