何謂類風濕性關節炎？ 類風濕性關節炎 是一種慢性（長期）疾病，大多數情況下影響關節，例如腕關節、手、腳、脊柱、膝蓋和下頜。類風濕性關節炎造成的炎症可導致關節： 疼痛。 腫脹。 僵直。 喪失功能。 因為是免疫系統攻擊健康的關節組織，類風濕性關節炎是一種自身免疫性疾病。正常情況下，免疫系統幫助保護身體免於發生感染和疾病。 類風濕性關節炎可能讓您感覺異常疲倦，偶爾會發燒，而且食欲下降。類風濕性關節炎還可能造成心、肺、血液、神經、眼睛和皮膚的其他醫療問題。 治療可以幫助患者過上充實的生活。
何謂系統性紅斑狼瘡（狼瘡）？ 系統性紅斑狼瘡（狼瘡）是一種慢性（長期）自身免疫性疾病，可影響多個身體部位，包括： 皮膚。 關節。 心臟。 肺。 腎臟。 大腦。 在正常情況下，免疫系統會幫助保護身體免於發生感染和疾病。但當發生狼瘡時，免疫系統攻擊自身組織。這樣的攻擊會造成炎症，而且在某些情況下會造成永久性的組織損傷。 如果您患有狼瘡，則您可能有時候發病（急性發作），有時候健康（緩解）。狼瘡急性發作時的程度可輕可重，而且也沒有一定的規律。但如果接受治療，許多狼瘡患者可以管理這一疾病。
何謂骨關節炎？ 骨關節炎是一種關節疾病，是指關節內的組織隨著時間的推移而分解。這是最常見的關節炎類型，而且更常見於年長者。 骨關節炎患者通常有關節疼痛，而且在休息之後有短時間的關節僵直（難以移動）。最常累及的關節包括： 手（手指末端和拇指的起點和末端）。 膝蓋。 髖部。 頸部。 腰部。 骨關節炎對每個人的影響都有所不同。對有些人來說，骨關節炎不影響日常活動。而對其他人而言，骨關節炎會造成劇烈疼痛和殘障。
何謂異位性皮膚炎？ 異位性皮膚炎通常稱為濕疹。這是一種慢性（長期）疾病，造成皮膚炎症和刺激症狀，導致極度瘙癢。抓撓會引起： 發紅。 腫脹。 皸裂。 滲出透明液體。 結痂。 脫皮。 在大多數情況下，有時病情惡化（稱為急性發作），然後皮膚情況有所改善或症狀完全消失（稱為緩解）。 異位性皮膚炎是一種常見病症，任何人都可能患上。但異位性皮膚炎通常是在兒童期開始出現。異位性皮膚炎不會從一個人傳給另一個人。沒有人知道異位性皮膚炎的病因是什麼。根據症狀的嚴重程度，異位性皮膚炎患者的生活可能並不容易，但治療可幫助控制症狀。
What are sports injuries?

What are growth plate injuries? The growth plate is the area of tissue near the ends of long bones in children and teens that determines what length and shape the bone will be once it is done growing. Each long bone— the thigh bone, the bones in the forearm, and the bones in the hands and fingers—has at least two growth plates, one at each end. Once your child has finished growing, the growth plates close and are replaced by solid bone. The growth plates are weak areas of your child’s growing skeleton, making it easier to injure them.

Lupus flares can be mild to serious, and they do not follow a pattern. However, with treatment, many people with lupus
