Abstract:
Tissue infections or skin, skin structure, and deep seated soft tissue infections are general terms for infections of the entire skin layer including the subcutaneous and muscle tissue layers and their respective fascia structures. Infections of the different mediastinal fascias (mediastinitis) and retroperitoneal fascia infections also belong to this category. Due to the variability of their clinical presentation, skin and soft tissue infections can be classified according to different features. The following aspects can be used for classification: - anatomical structures, - pathogens, - necessity for urgent treatment, - extent of infection. - The incidence of skin and soft tissue infections in which MRSA (methicillin-resistent Staphylococcus aureus) is involved has been steadily increasing over the past 15 years. These wounds should be treated according to the same open treatment principles as other infected wounds. Since these infections are often superficial contaminations, antibiotic therapy is not indicated. If systemic infection occurs in form of MRSA sepsis, antibiotic therapy is indicated. - Several recent reports identified MRSA as the leading pathogen in SSTIs. It also causes 20% to 50% of diabetes-associated foot infections in several countries and is associated with worse outcomes than other pathogens.
Insights
Skin and soft tissue infections (SSTIs) are increasing, particularly those caused by methicillin-resistant Staphylococcus aureus (MRSA). While superficial MRSA infections may not need antibiotics, MRSA sepsis requires prompt treatment.
Area of Science:
- Infectious Diseases
- Dermatology
- Microbiology
Background:
- Skin and soft tissue infections (SSTIs) encompass a range of conditions affecting skin, subcutaneous, and muscle tissues.
- Classifications of SSTIs consider anatomical structures, causative pathogens, urgency of treatment, and infection extent.
- The incidence of MRSA (methicillin-resistant Staphylococcus aureus) in SSTIs has risen significantly over the last 15 years.
Purpose of the Study:
- To review the classification and management of skin and soft tissue infections.
- To highlight the increasing role of MRSA in SSTIs and its treatment implications.
Main Methods:
- Literature review of SSTI classification and epidemiology.
- Analysis of MRSA prevalence and impact on patient outcomes.
Main Results:
- MRSA is identified as a leading pathogen in SSTIs, contributing to 20-50% of diabetes-associated foot infections in some regions.
- Superficial MRSA contaminations generally do not require antibiotic therapy.
- Systemic MRSA infections, such as MRSA sepsis, necessitate antibiotic treatment.
Conclusions:
- SSTIs require classification based on various clinical and etiological factors.
- The increasing prevalence of MRSA in SSTIs demands careful consideration of treatment strategies.
- Antibiotic therapy for MRSA SSTIs is reserved for systemic infections like sepsis.

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
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...
Factors Affecting the Risk of Infection
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 create...
