概括

膝关节置换手术后周围假肢关节感染的重复复查率为19.8%. 部插件更换和单阶段修复膝关节置换的风险比双阶段修复更高.

科学领域:

整形外科手术整形外科手术
传染性疾病传染性疾病
医疗保健服务研究医疗服务研究

背景情况:

周围假肢关节感染 (PJI) 是膝关节全关节整形术 (TKA) 后的一个重大并发症.
管理PJI对全球医疗保健系统构成了越来越大的挑战.
本研究调查了加拿大安大略省的PJI管理策略.

研究的目的:

分析TKA后管理PJI的方法.
评估PJI的不同修订策略的结果.
为了确定修复和重复修复手术的预测因素.

主要方法:

使用行政数据库 (2012-2019) 的回顾性队列研究.
确定的TKA患者和那些为PJI修订的患者.
分类修订分为骨插入交换 (TIE),单阶段 (ssrTKA) 和两阶段 (tsrTKA).

主要成果:

0.7%的TKA (660/98,384) 导致PJI需要修订.
两阶段修订 (tsrTKA) 是最常见的 (40.8%),其次是TIE (38.6%) 和ssrTKA (20.6%).
2年内整体重复修订率为19.8%;ssrTKA的比例最高 (27.9%).

结论:

近20%的接受PJI手术治疗的患者面临重复修订,通常是由于持续的感染.
与TSRTKA相比,部插入交换和单阶段修订TKA与更高的重复修订风险有关.
单阶段修订TKA显示感染根除的结果比tsrTKA更差.

Acute Pyelonephritis II: Diagnostic Studies and Management

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Healthcare Associated Infections II: Preventive Measures

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care

A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...

Factors Affecting the Risk of Infection

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
