Paediatrics: how to manage pediculosis capitis

Area of Science:

• Dermatology
• Parasitology
• Public Health

Background:

• Pediculosis capitis is a widespread parasitic infestation primarily affecting children.
• Effective management strategies are crucial to control its spread and impact.

Purpose of the Study:

• To provide an updated narrative review on the current management of pediculosis capitis.
• To synthesize evidence on various treatment options and their efficacy.

Main Methods:

• A comprehensive literature search was conducted on PubMed using keywords such as "pediculosis capitis" and "head lice."
• The review included clinical trials, meta-analyses, and other relevant studies published within the last decade.
• Articles were restricted to those published in English.

Main Results:

• Topical permethrin and pyrethrin are recommended where resistance is low.
• Alternative topical treatments include malathion, benzyl alcohol, dimethicone, spinosad, and ivermectin for resistant cases.
• Oral ivermectin and trimethoprim/sulfamethoxazole are reserved for treatment failures.

Conclusions:

• Multiple topical pediculicides are effective, but safety concerns exist for children under two.
• Pediculicide resistance, particularly to neurotoxic agents, is a significant challenge.
• New treatments require rigorous evaluation for safety and effectiveness; wet combing alone is insufficient.
