Internal medicine doc here but in my differential is Adult Onset Stills Disease which can still present in children and Rocky Mountain Spotted Fever. The salmon colored rash lasting a few minutes is textbook for Adult Onset Stills Disease.I'm assuming she had blood cultures done at one or multiple points during her admission. Did she have a procalcitonin tested? Did she receive any antibiotics? Any steroids like solumedrol, prednisone etc? Does she still have joint pain? Does this rash show up only during febrile episodes? Any auto immune conditions in the family like lupus, rheumatoid arthritis, hashimotos?
Doctors please help my little sister, she can't walk, I'm afraid she's going to die8F, 78lbs, no medication. She was in the hospital for a long time but they discharged her. She is still in pain, please help. I attached the notes of her discharge.The patient is an 8-year-old white female with five weeks of fever, rash, arthralgias. Last month, the patient noted foot pain involving both left and right feet, as well as a blotchy pink rash on the leg that proceeded to spread to the trunk and then arms and then face during that week. The patient had low-grade fevers with temps to a max of 101. This has progressed to the week prior to admission higher fevers with T-max of 103.5. The patient has endorsed muscle pain, particularly in the right leg and arm, and PMD had seen the patient this week noted right knee and right index finger swelling. There is no noted weight change over this time period. No noted diarrhea or swollen nodes. The rash the patient described the week prior had an acute abrupt onset and 5-10 minutes later would dissipate.Rheumatology was consulted on the patient from admission. Lab studies were sent to rule-out an infectious etiology for rash. Strep culture was negative. EKG was also performed to rule-out a prolonged PR interval. EKG was within normal limits. A DNase B antibody was 547 and an ASO titer was 300. While results were elevated, the patient did no meet clinical criteria for rheumatic fever and diagnosis that was most likely entertained was systemic JIA. Further lab work included an ANA which was negative, rheumatoid factor which was negative, a CRP on admission was 8.6 mg/dL with an ESR about 80. CK and aldolase were within normal limits. Ferritin was elevated at 663. LDH was within normal limits. CBC was reassuring with normal white counts, hemoglobin and platelets; findings nonsuggestive of leukemia. Hepatic panel within normal limits. A chest x-ray was done to rule-out mediastinal mass, and that was negative. From an infectious standpoint, Parvo, CMV, EBV were all negative. Clinically the patient was noted to have a salmon-colored transient rash that would come and go throughout the hospitalization lasting a matter of minutes. No definite arthritis on examination. Oncology was consulted given the history of arthritis and fevers. It was felt in the setting of normal cell lines in evaluating a smear, which revealed no blasts, no indication of hepatomegaly or splenomegaly and uric acid and LDH within normal limits and x-ray that was normal, they felt that further oncologic evaluation was not indicated and a bone marrow was not indicated at that time. Cardiology was also officially consulted because the patient had a 2/6 ejection murmur on the exam. Cardiology felt the murmur was a flow murmur and evaluated the EKG, which they read as within normal limits, and decided an echo was not indicated to rule-out valvular disease in the setting of the rash and arthritis in an attempt to workup acute rheumatic fever.
