丰富液体介质,血液培养瓶和超声波液体培养疗效的评估.

主要成果:

早期和晚期急性PJIs在5天内被诊断出 (97.1%和98.1%).
晚期慢性PJI需要14天才能诊断97.1%.
丰富的液体介质改善了物种检测,特别是对于多微生物/无氧感染.
血液培养瓶和超声波液体培养证明了卓越的诊断价值.

结论:

临床表现,而不是手术后的时间,应该指导PJIs的潜伏期.

Pneumonia I: Introduction

Pneumonia I: Introduction

Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...
