Summary

Family physicians commonly encounter bacterial skin infections like cellulitis and impetigo. Empirical antibiotic treatment targeting gram-positive bacteria is typical, with special considerations for high-risk patients.

Area of Science:

  • Dermatology
  • Infectious Diseases
  • Family Medicine

Background:

  • Bacterial skin infections are common in primary care settings.
  • Key infections include cellulitis, erysipelas, impetigo, folliculitis, furuncles, and carbuncles.
  • These infections are typically diagnosed clinically and managed empirically.

Purpose of the Study:

  • To provide an overview of common bacterial skin infections encountered by family physicians.
  • To discuss the typical causative agents and clinical presentations.
  • To outline appropriate empirical antibiotic selection and considerations for specific patient populations.

Main Methods:

  • Review of common bacterial skin infections.
  • Description of causative organisms (e.g., Streptococcus, Staphylococcus).
  • Discussion of diagnostic criteria and empirical treatment strategies.

Main Results:

  • Cellulitis and erysipelas present with varying border demarcation and are often caused by Streptococcus or Staphylococcus.
  • Impetigo can manifest with bullous lesions.
  • Folliculitis, furuncles, and carbuncles involve hair follicles and may require incision and drainage.
  • Empirical antibiotic choices include penicillinase-resistant penicillins, cephalosporins, macrolides, or fluoroquinolones for gram-positive coverage.

Conclusions:

  • Bacterial skin infections are a frequent concern for family physicians.
  • Clinical diagnosis and empirical treatment are standard practices.
  • Antibiotic selection should target common gram-positive pathogens, with adjustments for patients at risk for gram-negative infections.
