Clinical Classification Guidelines
Inclusion Terms
- Head-louse infestation
Medical Intelligence & Overview
Pediculosis capitis, commonly known as head lice infestation, is a frequent condition caused by the infestation of the scalp with head lice (Pediculus humanus capitis). These tiny insects latch onto the scalp and feed on blood, leading to itching and discomfort. Though more common among children, anyone can get head lice, especially in environments where close contact and sharing personal items are common. The condition is contagious but is not linked to poor hygiene.
Causes & Symptoms
Clinical Causes: Close personal contact with an infested person Sharing hats, combs, hairbrushes, or pillows with an infested individual Living in crowded conditions where lice can spread easily Contact with infested clothing or bedding School or daycare environments where infestations are common
Key Symptoms: Intense itching on the scalp, often worse at night Sensation of something crawling or moving on the scalp Sores or red bumps caused by scratching Lice eggs (nits) attached to hair shafts, often near the scalp Irritation and discomfort in the affected areas
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a physical examination of the scalp and hair. A healthcare provider looks for live lice, nits, and signs of scratching. Using a fine-toothed comb through the hair can help identify nits attached close to the scalp. In some cases, additional microscopic examination may be needed to confirm the presence of lice or eggs.
Treatment Protocols: Effective treatment of head lice involves approved medicated shampoos or topical agents designed to kill lice and their eggs. Common treatments include over-the-counter formulations containing permethrin or pyrethrin. It's important to follow the instructions carefully, repeating treatment if necessary after a week. Physical removal of nits with a fine-toothed comb can help reduce infestation. Cleaning personal items like hats, bedding, and clothing thoroughly is also advised to prevent re-infestation. In resistant cases, healthcare providers may recommend alternative medications or treatment strategies.
