Burn Injuries01:22

Burn Injuries

2.5K
Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

Skin Diseases and Disorders

3.8K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

4.2K
Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

11.8K
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...

Infection01:20

Infection

7.8K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Surface Membrane Barriers01:18

Surface 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...

Area of Science:

  • Infectious Diseases
  • Burn Care
  • Microbiology

Background:

  • Polymicrobial infections are a leading cause of complications in burn patients.
  • Hospitalized burn patients face a high risk of hospital-acquired infections, particularly multidrug-resistant (MDR) pathogens.
  • Burn wound infections (BWIs) are frequently caused by opportunistic pathogens, with variations influenced by geography and infection control.

Purpose of the Study:

  • To highlight the common causative agents of BWIs, focusing on multidrug-resistant Gram-negative bacteria.
  • To emphasize the systemic effects of burn injuries, including immune response and immunosuppression.
  • To underscore the importance of early detection, treatment, and collaborative care in managing BWIs.

Main Methods:

  • Literature review of common pathogens and complications in burn wound infections.
  • Analysis of the impact of burn injuries on the host immune system.
  • Discussion of the role of multidisciplinary collaboration in combating antibiotic resistance.

Main Results:

  • Common MDR Gram-negative bacteria in BWIs include Acinetobacter baumannii, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Proteus mirabilis.
  • Burn injuries induce elevated serum cytokine levels, systemic immune response, and immunosuppression.
  • Viral and fungal infections occur less frequently but contribute to the overall infectious burden.

Conclusions:

  • Early detection and treatment of BWIs are essential for accelerating wound healing and preventing secondary infections.
  • Effective management requires a multidisciplinary approach involving burn surgeons and infectious disease specialists.
  • Monitoring antibiotic resistance and controlling the spread of MDR pathogens are critical for improving patient outcomes in burn care.
