Rheumatology: Kawasaki, Henoch-Schonlein Purpura, Chronic Pain Flashcards
Kawasaki Syndrome: Diagnostic Criteria of CDC (5)
- Fever > 5 days
- Presence of 4 of 5 following:
a. Bilateral conjunctiva injection
b. Changes in mucous membranes of upper respiratory tract
c. changes of peripheral extremities - Rash: primarily truncal, polymorphic
- Cervical Lymphadenopathy
- Illness that cannot be explained by other known disease processes
Kawasaki Mucutaneous Lymph Node Syndrome (4)
a. Asians highest % affected
b. Risk to blacks> whites
c. Males> females
d. Peak age 6 months - 2 years (75% before age 5 years)
Kawasaki Phases (3)
- Acute: up to 11 days
- Sub-acute: 11-21 days
- Convalescent: 21-60 days
Acute Kawasaki Clinical Picture (6)
- Erythema./edema hands/feet
- Irritable, conjunctivitis
- Fever, oral findings, rash
- Early form of arthritis/ arthralgia- small and large joints
- Lethargy, diarrhea, abdominal pain,
- Pericarditis, pericardial effusion, myocarditis
Sub-Acute Kawasaki Clinical Picture (4)
- Desquamantion of hands/toes abdominal pain, hepatitis
- Oral findings may persist edema
- Joint pain may persist
- Arterial aneurysms form now- Now is when are at risk for MI or rupture
Kawasaki: Worrisome signs of probability of Cardiac involvement (7)
- Males
- Age < 12 months
- Recurrent fevers after defervesence
- Recurrence of rash
- Exaggerated leukocytosis
- > ESR
- Cardiac dysrhythmias
Kawasaki Convalescent stage (3)
- Symptomatology should start to resolve
- Must keep watch on those with aneurysms - followed by cardiology as needed
- Recurrence is rare but can happen
Kawasaki Labs (6)
- CBC, ESR, Platelet
- Chemistries
- Blood Cultures
- Urine Cultures
- CSF
- ANA, ASLO, RF
Kawasaki Differentials (8)
- Scarlet fever
- Staph, scalded skin syndrome
- Toxic shock
- Rocky mountain Spotted fever
- Rubeola
- JRA
- SLE
- Polyarthteritis nordosa
Kawasaki Treatment (4)
a. IV IGG
b. Aspirin
c. Cardiac Echo
d. Close follow-up
Henoch-Schonlein Purpura (4)
- Most common vasculitis of childhood
- 75% of cases occur b/w ages 2-11 yrs
- Etiology unknown
- Some have been associated with post EBV, adenovirus, enteric bacteria, streptococcus, s/p URI
Henoch-Schonlein Purpura: Signs and Symptoms (7)
- Purpuric rash
- Abdominal pain
- Arthritis
- Nephritis
- Intussusception (2-3%)
- Scrotal swelling
- Renal involvement (20-50%)
Henoch-Schonlein Purpura: Treatment (2)
- Supportive care
- Role of corticosteroids controversial:
* May improve rash, arthritis and abdominal pain
* Unclear if reduce progression of renal disease
