Lower limb cellulitis and its mimics: part I. Lower limb cellulitis.

Area of Science:

• Infectious Diseases
• Dermatology
• Epidemiology

Background:

• Lower limb cellulitis incidence is rising, linked to an aging population and increased obesity rates.
• Key predisposing factors include advanced age, obesity, venous insufficiency, prior saphenous venectomy, and edema.
• Streptococci are the primary causative pathogens, often originating from interdigital toe spaces.

Purpose of the Study:

• To summarize the epidemiology of lower limb cellulitis.
• To outline the effective management and treatment strategies for lower limb cellulitis.
• To highlight the importance of addressing predisposing factors in managing this infection.

Main Methods:

• Review of epidemiological data on lower limb cellulitis.
• Summary of common pathogens and their sources.
• Analysis of current treatment guidelines and management approaches.

Main Results:

• Aging and obesity are significant contributors to the increasing incidence of lower limb cellulitis.
• Older age, obesity, venous insufficiency, saphenous venectomy, and edema are critical predisposing factors.
• Streptococci are the most frequent pathogens, with interdigital spaces being a common reservoir.

Conclusions:

• Effective management necessitates appropriate antibiotic therapy.
• Addressing underlying predisposing factors is crucial for successful treatment and prevention of recurrence.
• This article provides a comprehensive overview of cellulitis epidemiology and treatment.
