まとめ
血液溶解性尿性症候群 (HUS) の子供の皮膚ガングレナは,シガ毒素を生成する大腸菌HUS (STEC-HUS) を示す可能性があります. STEC-HUSと非典型的なHUS (aHUS) を区別することは,適切な治療と予後のために極めて重要です.

研究 の 目的:
- STEC-HUS.USにおける皮膚の関与による診断上の課題と治療上の影響を強調する.
- STEC-HUSとaHUSを皮膚症状のある小児症例で区別する重要性を強調する.
主な方法:
- 3歳の男の子が重度のHUSを患ったケース報告.
- 臨床表現,検査結果,皮膚生検を含む診断検査,治療経路などについて説明しています.
- STEC感染の特定検査を通じて,aHUSおよび他のTMAの原因を除外する.
主要な成果:
- 患者は攻撃的なHUSを発症し,透析と機械呼吸器を含む集中治療を必要とした.

970
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

1.6K
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.
