Area of Science:

  • Dermatology
  • Primary Care Medicine

Context:

  • This study was conducted at the Mariñamansa-A Cuña Health Centre in Ourense.
  • It involved 130 patients presenting with cutaneous lesions treated with cryotherapy between March and April 2000.

Purpose:

  • To evaluate the efficacy, tolerance, and safety of cryotherapy utilizing nitrous oxide in a primary care setting.
  • To analyze patient demographics, lesion characteristics, treatment parameters, and outcomes.

Summary:

  • The study included 130 patients with a mean age of 36.65 years, predominantly women (53.8%). Common warts constituted the majority of lesions (68.5%), frequently located on upper limbs.
  • Cryotherapy with nitrous oxide demonstrated a total cure rate of 87.7%, with good tolerance (83.8%) and minimal side effects, primarily blisters. Mean treatment involved 2.82 sessions.

  • Treatment failure was most noted in common warts. Prior treatments like scraping (69.7%) and keratolysis (16.2%) were sometimes employed.

    • Impact:

    • Nitrous oxide cryotherapy is confirmed as an effective and well-tolerated treatment for various skin lesions in primary care.
    • The technique's ease of use and safety profile support its integration into routine primary care dermatological practice.
    • Findings provide valuable data for clinicians managing common cutaneous conditions using cryotherapy.
