Purpura Flashcards
1
Q
Hypergammaglobulinaemic Purpura of Waldenstrom pathogenesis
A
- associated with hypergammaglobulinaemia
- presence of small circulating immune complexes containing IgG or IgA RF –> these are really soluble so might explain the rapdiity which lesions appear and resolve
- increased development of autoimmune and lymphoproliferative disorders
2
Q
Hypergammaglobulinaemic Purpura of Waldenstrom clinical
A
- slight itch, mild tingling, burning
- may be aggravated by tight-fitting garments, prolonged standing and heat
- macular haemorrhage on lower extremities, these can be fleeting
- sometimes palpable purpura
- can be:
- Primary: young patients
- Secondary: autoimmune connective tissue disease (Sjogren or RA or lupus), or rarely a monoclonal gammopathy, lymphoma or multiple myeloma
- Investigations: polycloncal hypergammaglobulinaemia and elevated ESR
- standard RF assays only check IgM so this will come back normal, you need to order the IgG and IgA
- Anti-SSA/Ro and SSB/La are often positive
3
Q
Hypergammaglobulinaemic Purpura of Waldenstrom treatment
A
- avoid precipitating factors: alcohol, prolonged standing
- used to use support stockings and aspirin but that can actually flare it
- ?colchicine
4
Q
Gardner Diamond clinical
A
- Psych: depression, anxiety, difficulties handing aggression and hostility, hypochondriacs, etc
- Sudden onset of painful, swollen bruises of variable size in any area of the body
- resolve within 2 weeks, and then recur
- reports of injection of own blood brings it on
5
Q
Gardner Diamond treatment
A
rx: psych management, very difficult to treat
6
Q
Mondor Syndrome of Superficial Thrombophlebitis pathogenesis
A
- pathogenic factors: trauma, excessive physical activity, surgery, mastitis, breast abscess, pendulous breasts
- 10% have underlying breast carcinoma
- can be associated with rheumatoid arthritis, filariasis, pregnancy, OCP, IVDU, IV catheters, other malignancies, hypercoagulable states
7
Q
Mondor Syndrome of Superficial Thrombophlebitis clinical
A
- sudden onset of chest pain with one or more visible or palpable cords
- associations: tenderness, sensation of tension, erythema, ecchymosis, pruritis, arthralgia, fever
- worsens with pulling the skin or elevating the breast and ipsilateral extremity
- is unilateral
- F>M
8
Q
Mondor Syndrome of Superficial Thrombophlebitis treatment
A
- and self limited, except when associated with breast cancer
- rate of recurrence ~5%
- NSAIDs, LMWH
- superficial venous thrombosis involving the main trunk of the saphenous bein has the strongest associated with VTE: if near the sapheno-femoral or sapheno-popliteal it needs to be removed
9
Q
Papular purpuric gloves and socks syndrome
A
Viral rash resulting in painful redness and swelling of the feet and hands. Most common cause parvovirus B19, EVB
Is rapidly progressive
Can result in polyarthropathy, aplastic crises, intrauterine death
