B sx
How do you diagnose and treat giant cell a?
Temporal artery biospy (not 100% sen. due to skip lesions) Check ESR (raised)
High dose oral prednisolone (do not delay)
Which condition is associated with giant cell a?
Polymyalgia rheumatica => >50yo, 15% get GCA => increased ESR/CRP => bilateral shoulder and girdle pain, morning stiffness, chronic, no weakness O/E => treat with oral steroids
Polyarteritis nodosa summary card
Idiopathic, associated with Hep B.
Sx => renal failure, hypotension, abdo pain, skin rash, rectal bleeding, peripheral neuropathy, constitutional upset
Ix => Rosary sign (pearl necklace) in CT abdo due to adenomyomatosis of gallbladder
Granulomatosis w/ polyangitis summary card
AKA Wegener’s syndrome
=> saddle nose, upper respiratory tract (rhinitis, nose bleeds), kidneys (glomerulonephritis), lower respiratory tract (haemoptysis)
=> cANCA
=> cavitating lesions on CXR
Churg-Strauss syndrome summary card
Eosinophilic granulomatosis w/ polyangitis
=> haemoptysis, rash, kidney damage, focal neuroapthy
=> allergic (asthma/rhinitis), eosinophilic (high eosinophils damage lungs and GIT), vasculitic (widespread organ damage and death)
=> pANCA
Behcet’s disease summary card
Affects pts from Mediterranean; Greece/Cyprus
=> pericarditis, colitis, arthritis, rash
=> recurrent oral ulcers, genital ulcers, uveitis*
=> clinical diagnosis, can do pathergy test (needle prick inflamed and sterile pustule develops within 48hrs)
Takayasu’s arteritis summary card
Asian women, 20-40yo
=> FLAWS (inflammatory phase)
=> weak/absent UL/LL pulses, claudication (pulseless phase)
Goodpasture’s syndrome summary card
TRIAD:
=> glomerulonephritis
=> haemoptysis (pulmonary haemorrhage)
=> anti-GBM antibodies
A 40-year-old Afro-Caribbean man has suffered from shortness of breath and a dry cough for the last 3 months. He also complains of some ‘sore lumps on his shins’. Closer inspection reveals tender violet nodules on both shins. A chest X-ray is requested, which shows bilateral hilar lymphadenopathy. Blood tests are also requested, including U&Es – which parameter would you expect to be raised?
A Sodium B Potassium C Calcium D pH E Urea
C Calcium
A 33-year-old female with SLE presents to the fertility clinic complaining that she has been desperately trying to start a family but has had repeated miscarriages. She has had 3 miscarriages in the past 5 years. She has a past medical history of asthma and two DVTs. Given the likely diagnosis, which of the following antibodies is associated with this disease?
A Anti-CCP antibody B Anti-Jo-1 antibody C Anti-centromere antibody D Anti-cardiolipin antibody E Anti-smooth muscle antibody
D Anti-cardiolipin antibody
A 58-year-old woman presents to her GP complaining of difficulty swallowing which started 6 months ago. On examination, the skin on her hands appears thickened and tight around her fingers. Furthermore, a hard lump is felt under the skin on her left thumb. Which of the following additional clinical features would support a diagnosis of limited cutaneous systemic sclerosis?
A Telangiectasia B Thickened skin on the chest C Macroglossia D Buccal pigmentation E Cherry haemangioma
A Telangiectasia
A 63-year-old woman presents to A&E with a headache, mainly affecting the left half of her forehead, that has gradually been getting worse over the past week. She has been eating less as she experiences pain in her jaw when she chews her food. She has, generally speaking, been healthy aside from experiencing some stiffness and pain in her shoulders over the past 6 months. What is the first step in her management?
A Check ESR B Temporal artery biopsy C IV hydrocortisone D Oral prednisolone E IV antibiotics
A Check ESR
Which of the following conditions is strongly associated with temporal arteritis?
A Takayasu’s aortitis B Myalgic encephalomyelitis C Fibromyalgia D Polymyalgia rheumatica E Polymyositis
D Polymyalgia rheumatica
A 47-year-old man visits his GP having developed a skin rash. He has been feeling ‘generally unwell’ for the past 3 months, and has suffered from abdominal pain accompanied by some rectal bleeding. An angiogram reveals ‘Rosary sign’. He regularly attends hospital for check-ups since he was diagnosed with chronic hepatitis B, 2 years ago. What is the most likely diagnosis?
A Giant cell arteritis B Dermatomyositis C Polyarteritis nodosa D Granulomatosis with polyangiitis E Behcet’s disease
C Polyarteritis nodosa
