概括
微生物污染影响近40%的隐形眼镜和配件,其中镜头外是最受污染的. 恶劣的卫生习惯,尤其是在年轻人中,增加了来自病原体的眼部感染的风险,如金黄色葡萄球菌.
科学领域:
- 眼科医生 眼科 眼科
- 微生物学 微生物学
- 公共卫生 公共卫生
背景情况:
- 隐形眼镜 (CL) 佩戴是常见的,但隐形眼镜和配件的微生物污染对眼睛健康构成重大风险.
- 了解污染源和用户行为对于预防隐形眼镜相关感染至关重要.
研究的目的:
- 在无症状用户中评估软隐形眼镜及其相关配件上的微生物污染水平.
- 识别导致微生物污染增加和潜在的眼部感染的行为风险因素.
主要方法:
- 从95个无症状的软CL用户收集了380个样本,包括镜头,盒子,多用途溶液瓶和溶液.
- 使用基于培养的方法 (血液,MacConkey,Pseudomonas,Sabouraud dextrose) 和生物化学测试进行微生物识别.
- 管理一个问卷以评估用户遵守卫生和护理程序.
主要成果:
- 总体微生物污染率为38.7%,镜头 (62.1%) 和瓶子 (46.3%) 的污染率最高.
- 凝聚酶阴性葡萄球菌 (CoNS) 和阳性杆菌是主要的微生物.
- 确定的病原体包括金黄色葡萄球菌, Pseudomonas aeruginosa,大肠杆菌和白菌. 年轻的使用者 (18-20岁) 表现出不良的卫生遵守.
结论:
- 不足够的隐形眼镜护理实践与高污染率有关,特别是在隐形眼镜的情况下,增加了毒性病原体暴露的风险.
- 诸如男性性别,吸烟,淋浴或戴眼镜游泳等行为因素与增加的微生物污染有关.
- 不遵守清洁协议可能导致微生物殖民,可能导致未来的炎症性眼病.

01:18Surface Membrane Barriers
1.1K
The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

01:25Transmission-based Precautions II: Airborne and Protective Environment
1.2K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...
