Nonsuppurative cervical lymphadenopathy (usually unilateral, with node size >1.5cm).
Acute febrile phase - fever and the acute signs of illness and usually lasts 1-2wks
Subacute febrile phase - desquamation, thrombocytosis, coronary aneurysms and highest risk of sudden death usually lasts 2 wks
Convalescent phase - All clinical signs have disappeared until ESR normalizes typically 6-8wks after onset on illness

C. Henoch-Scholein purpura
D. SLE E. Juvenile Rheumatoid arthritis - ANSWER - 2 C.
HSP is a common vasculitis among children and presents with the classic findings of abdominal pain with or without rectal bleeding, vasculitis rash, arthritis and nephritis. The platelet count is normal. Gastrointestinal involvement may progress to intussusception.

A 3 Test Bank For Pediatrics 19th Ed By Nelson 700 Questions 100% Answered Correct 2024 Solutionyear old female presents with 1 week history of daily (quotidian) fever associated with arthritis of both ankles and her right knee. Her mother notes that she has decreased activity and also notes rashes that come and go in different parts of her body but not on the face. On physical examination, salmon colored patches were noted on the trunk and extremities. Palpation revealed splenomegaly. What is the diagnosis?
A. Henoch Schoenlein Purpura
B. Systemic Lupus Erythematosus
C. Juvenile Rheumatoid arthritis
D. Juvenile Dermatomyositis
E. Dengue fever - ANSWER - 3 C.
Don't forget to study rheumatic diseases of childhood even if it's not your favorite topic.
Familiarize yourself with the relatively common ones like JRA, SLE and dermatomyositis, HSP and scleroderma. Pay attention to the characteristics of the rash and other features. (Don't fall for the trap of rash + arthritis = SLE.. It's not always SLE!)
JRA - Salmon colored patch, evanescent, spares the face
SLE - Malar rash, photosensitive
Dermatomyositis - heliotrope (periorbital) rash, gottron papules (rash on the knuckles)
HSP - purpura in dependent portions
For JRA, know the differences between subtypes (oligoarticular vs polyarticular vs systemic onset)
This case in particular is a case of systemic onset Juvenile Rheumatoid arthritis (also called Still's Disease)

A. PCR for ADA deficiency
B. Nitroblue tetrazolium test
C. MAC-I assay
D. Neutrophil count
E. Genetic chromosomal analysis - ANSWER - 4 B. This is a case of chronic granulomatous disease (CGD) wherein patients are susceptible to catalase positive organisms like S. aureus. The nitroblue tetrazolium tests the neutrophils ability to generate superoxide anion and thus kill ingested bacteria.
