Kawasaki Disease: FEVER + 4 of the ff features:
Clue: C-R-A-S-H
Conjunctivitis
Rash
Adenopathy
Strawberry tongue and other oropharyngeal changes
Hand changes (brawny edema, induration, peeling around nail beds)
Treatment of kawasaki disease in the acute stage
Acute stage: IV Ig (2g/kg) and Aspirin (80-100mg/kg/day) q6h until afebrile
Convalescent: Aspirin 3-5mg/kg OD
Long term therapy w/ coronary abnormalities: Aspirin & Clopidogrel
8 year old female presents with 3 month history of fever ranging from 37.8 to 38.5C, weight loss, irritability, and joint pains. She also has some muscle weakness and has difficulty climbing the stairs and combing her hair sometimes. She also started having a violaceous erythematous rash near the periorbital area that extends to the nose, current PE: HR 90, RR18, T>37.5C, characteristic rash over the face, (+) muscle weakness 4/5 over biceps and hips, (+) reddish pink colored skin over the dorsal surfaces of the metacarpal joints, what is the most likely diagnosis?

A. dermatomyositis -most common pediatric myopathy
Systemic vasulopathy with characteristic cutaneous findings and focal areas of myositis resulting in progressive proximal muscle weakness.
Juvenile Dermatomyositis
Gottron Papules- alligator skin appearance
Heliotrope eyelids/rash- periorbital violaceous erythema that may cross over the bridge of the nose
Clinical manifestation of Juvenile Dermatomyositis:
- Neck flexor and abdominal muscle weakness
- unable to sit up or head lag during infancy, and Gower sign
- derangement of upper airway function
- dysphagia (severe prognostic sign)
- constipation, abdominal pain, diarrhea
- dilated cardiomyopathy
What is not a diagnostic criteria for juvenile dermatomyositis? A. Heliotrope rash B. Asymmetric weakness C. Muscle enzyme elevation D. Myopathy E. None of the above
B. Asymmetric weakness
Diagnostic criteria:
Classic rash (heliotrope rash of the eyelids, Gottron papules) PLUS 3 of the ff:
1. Weakness (symmetric, proximal)
2. Muscle enzyme elevation:
CK, aspartate, aminotransferase (most commonly elevated), LDH, aldolase
3. Electromyographic changes (myopathy, denervation)
4. Muscle biopsy (necorsis, inflammation)
TRUE or FALSE. IVIG is given for severe cases in Juvenile Dermatomyositis
TRUE
Corticosteroids also given: methylprednisolone for more severe cases
Methotrexate decreases the length of treatment with steroids
