Write answer in between .Q:A 4-year-old girl is brought to the physician with a 3-month history of progressive intermittent pain and swelling involving both knees, right ankle, and right wrist. The patient has been undergoing treatment with acetaminophen and ice packs, both of which relieved her symptoms. The affected joints feel stuck and are difficult to move immediately upon waking up in the morning. However, the patient can move her joints freely after a few minutes. She also complains of occasional mild eye pain that resolves spontaneously. Five months ago, she was diagnosed with an upper respiratory tract infection that resolved without treatment. Vital signs are within normal limits. Physical examination shows swollen and erythematous joints, which are tender to touch. Slit-lamp examination shows an anterior chamber flare with signs of iris inflammation bilaterally. Laboratory studies show:Blood parametersHemoglobin 12.6 gdLLeukocyte count 8,000mm3Segmented neutrophils 76Eosinophils 1Lymphocytes 20Monocytes 3Platelet count 360,000mm3Erythrocyte sedimentation rate 36 mmhrSerum parametersAntinuclear antibodies 1:320Rheumatoid factor negativeWhich of the following is the most likely diagnosis?? A: Acute lymphocytic leukemia, B: Enthesitis-related arthritis, C: Oligoarticular juvenile idiopathic arthritis, D: Postinfectious arthritis, E: Seronegative polyarticular juvenile idiopathic arthritis,  <response>: This is a clinical vignette describing a 4-year-old girl with a 3-month history of progressive intermittent pain and swelling of the knees, right ankle, and right wrist. The symptoms are worse in the morning but improve with movement. There is also mild eye pain. On exam, there is joint swelling, tenderness, and signs of iris inflammation. Lab findings show a mildly elevated ESR, positive ANA, and normal RF. Based on the young age of onset, pattern of joint involvement kneesankles, morning stiffness improving with movement, eye inflammation, elevated inflammatory markers, and positive ANA, this presentation is most consistent with juvenile idiopathic arthritis JIA. The oligoarticular subtype of JIA is suggested by involvement of 4 or fewer joints in the first 6 months of disease. The negative RF makes polyarticular JIA less likely. No systemic symptoms or spiking fevers makes systemic JIA less likely. Postinfectious and leukemia would not explain the chronicity or pattern of jointeye findings.C: Oligoarticular juvenile idiopathic arthritis
