Hand hygiene

4.9K
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.

Clinical Applications of Epidermal Stem Cells

3.0K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

Cells of the Epidermis01:24

Cells of the Epidermis

6.0K
The epidermis is made of four or five layers of epithelial cells, depending on its location in the body. From deep to superficial, these layers are the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.
The cells in all these layers except the stratum basale are called keratinocytes, a type of cell that manufactures and stores the protein keratin. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from...

Cleaning, Sterilization, and Disinfection

9.1K
Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

Area of Science:

  • Infectious Diseases
  • Dermatology
  • Public Health

Background:

  • Scrub typhus, a zoonotic disease caused by Orientia tsutsugamushi, presents with diverse symptoms.
  • Eschar, a necrotic lesion at the chigger bite site, is a pathognomonic sign but often overlooked.
  • The incidence of eschars in scrub typhus cases varies significantly.

Purpose of the Study:

  • To report a case of scrub typhus presenting with a notable eschar.
  • To emphasize the diagnostic significance of eschars in scrub typhus.
  • To highlight the importance of thorough clinical examination for early diagnosis.

Main Methods:

  • A 60-year-old female presented with fever, myalgias, and shortness of breath.
  • Clinical examination revealed tachypnea, hypoxia, and a characteristic eschar.
  • Diagnosis was confirmed by positive IgM rapid test and PCR on eschar biopsy.

Main Results:

  • The patient presented with symptoms consistent with severe scrub typhus.
  • A 1x1 cm eschar was identified on the left infraclavicular area.
  • Rapid diagnostic tests and PCR confirmed scrub typhus.
  • The patient responded well to doxycycline treatment and was discharged.

Conclusions:

  • Eschar presence is a critical indicator for scrub typhus diagnosis.
  • Missed eschars can lead to delayed diagnosis and treatment.
  • Thorough physical examination is essential for identifying eschars, especially in endemic areas.
  • Early diagnosis and treatment initiation, even before laboratory confirmation, improve patient outcomes.
