2024年風專筆試筆記-3

1. 2017 EULAR/ACR classification criteria for adult and pediatric IIM，以下何者為非？ (A) Age of onset of first symptom assumed to be related to the disease >=40 years (B) Neck extensors are relatively weaker than neck flexors (C) Gottron papules (D) Muscle biopsy features---presence of rimmed vacuoles

 根據2017 EULAR/ACR分類標準，年紀大於等於40歲會獲得2.1分，neck flexors弱於neck extensors會得到1.9分，Gottron's sign會獲得2.1分，與inclusion body myositis相關的rimmed vacuoles會獲得3.1分，因此錯誤的選項為(B)。分類標準主要包含：年紀、近端無力、皮膚表徵 (Helitrope sign & Gottron's sign)、anti-Jo-1 ab、抽血數值異常(CK、AST、ALT、LDH)、肌肉切片。
