Asepsis01:28

Asepsis

2.0K
The condition of being free from disease-causing living pathogens is asepsis. Aseptic techniques include a set of standard practices to achieve asepsis. An example is the regular environmental cleaning of all parts of the healthcare facility and hand hygiene at home before preparing or eating food. Medical and surgical asepsis in healthcare practice protects patients from harmful pathogens, minimizes the risk of contamination of susceptible sites, and reduces the risk of infection transmission.

Healthcare Associated Infections II: Preventive Measures

2.3K
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...

Pleural Effusion Overview
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.

Hand hygiene01:23

Hand hygiene

3.1K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Surface Membrane Barriers01:18

Surface Membrane Barriers

747
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...

Area of Science:

  • Orthopedics
  • Radiology
  • Infectious Diseases

Background:

  • Septic arthritis presents a significant global health challenge, leading to high morbidity, mortality, and long-term disability.
  • Early and accurate diagnosis is essential to mitigate severe joint damage, including cartilage destruction and osteomyelitis.

Purpose of the Study:

  • To comprehensively review the characteristic imaging findings of septic arthritis across multiple diagnostic modalities.
  • To highlight the role of imaging in guiding diagnostic aspiration and identifying complications.

Main Methods:

  • Review of hallmark imaging findings in septic arthritis using radiography, ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), and nuclear medicine scintigraphy.
  • Discussion of imaging applicability in native and prosthetic joints.

Main Results:

  • Each imaging modality presents unique indicators for septic arthritis, aiding in diagnosis and complication assessment.
  • Imaging findings vary depending on the affected joint and whether it is native or prosthetic.

Conclusions:

  • Imaging is indispensable for the timely diagnosis and management of septic arthritis.
  • Understanding modality-specific findings is crucial for optimizing patient outcomes and preventing long-term functional impairment.
