Head lice infestation is associated with limited morbidity but causes a high level of anxiety among parents of school aged children. Since the 2. 01. 0 clinical report on head lice was published by the American Academy of Pediatrics, newer medications have been approved for the treatment of head lice. This revised clinical report clarifies current diagnosis and treatment protocols and provides guidance for the management of children with head lice in the school setting.

It is important to note that head lice are not a health hazard or a sign of poor hygiene and are not responsible for the spread of any disease. Despite this knowledge, there is significant stigma resulting from head lice infestations in many developed countries, resulting in children being ostracized from their schools, friends, and other social events. In the past, parents and other nonhealth care personnel made the diagnosis of head lice, and the easy availability of safe and effective over the counter OTC pediculicides often removed the physician from the treatment process. However, the potential for misdiagnosis and the resulting improper use of pediculicides and the emergence of resistance to both available and newer products, many without proof of efficacy or safety, call for increased physician involvement in the diagnosis and treatment. Optimal treatments should be safe, should rapidly rid the individual of live lice, viable eggs, and residual nits, and should be easy to use and affordable. Additionally, because lice infestation is benign, treatments should not be associated with adverse effects and should be reserved for patients on whom living lice are found. Etiologic Agent. The adult head louse is 2 to 3 mm long the size of a sesame seed, has 6 legs, and is usually tan to grayish white in color. The female lives up to 3 to 4 weeks and, once mature, can lay up to 1. These tiny eggs are firmly attached to the base of the hair shaft within approximately 4 mm of the scalp with a gluelike substance produced by the louse. Viable eggs camouflaged with pigment to match the hair color of the infested person often are seen more easily at the posterior hairline. Hp Probook 4530S Network Adapter Drivers on this page. Empty egg casings nits are easier to see because they appear white against darker hair. Note that some experts refer to eggs as containing the developing nymph and use nits to refer to empty egg casings others use the term nits to refer to both eggs and the empty casings. The eggs are incubated by body heat and typically hatch in 8 to 9 days, but hatching can vary from 7 to 1. Once it hatches, a nymph leaves the shell casing and passes through a total of 3 nymph stages instars during the next 9 to 1. The female louse can mate and begin to lay viable eggs approximately 1. If not treated, the cycle repeats itself approximately every 3 weeks. The louse feeds by injecting small amounts of saliva, which has vasodilatory and anticoagulation properties, into the scalp, allowing the louse to suck tiny amounts of blood every few hours. Pruritus results from sensitization to components of the saliva. With a first case of head lice, pruritus may not develop for 4 to 6 weeks, because it takes that amount of time for sensitivity to result. Head lice usually survive for less than 1 day away from the scalp, and their eggs cannot hatch at temperatures lower than those near the scalp. Epidemiology. In the United States, reliable data on prevalence of head lice are not available. All socioeconomic groups are affected, and infestations are seen throughout the world. Head lice infestation is not significantly influenced by hair length or by frequent brushing or shampooing. Transmission. Lice do not hop or jump they can only crawl, and pets do not play a role in the transmission of human lice. However, there are reports that combing dry hair can build up enough static electricity to physically eject an adult louse from an infested scalp for a distance of 1 m. In most cases, transmission occurs by direct contact. Indirect spread through contact with personal belongings of an infested individual combs, brushes, hats is much less likely to occur. Lice found on combs are likely to be injured or dead,1. In 1 study, live lice were found on only 4 of pillowcases used by infested volunteers. Thus, the major focus of control activities should be to reduce the number of lice on the head and to lessen the risks of head to head contact. Diagnosis. Identification of eggs nits, nymphs, or adult lice with the naked eye establishes the diagnosis. This can be difficult sometimes because lice avoid light and can crawl quickly. Studies have revealed that diagnosis of infestation by using a louse comb is quicker and more efficient. Some experts have suggested using a lubricant water, oil, or conditioner to slow down the movement of lice and eliminate the possibility of static electricity. Tiny eggs may be easier to spot at the nape of the neck or behind the ears, within 1 cm of the scalp. It is important not to confuse eggs or nits, which are firmly affixed to the hair shaft, with dandruff, hair casts, or other hair debris, which are not. It is also important not to confuse live eggs with dead or empty egg cases nits. Many presumed lice and nits submitted by physicians, nurses, teachers, and parents to a laboratory for identification were found to be artifacts, such as dandruff, hairspray droplets, scabs, dirt, or other insects eg, aphids blown by the wind and caught in the hair. In general, eggs found more than 1 cm from the scalp are unlikely to be viable, although some researchers in warmer climates have found viable eggs farther from the scalp. Prevention. It is unlikely that all head lice infestations can be prevented, because young children come into head to head contact with each other frequently. It is prudent for children to be taught not to share personal items, such as combs, brushes, and hats, but one should not refuse to wear protective headgear because of fear of head lice. In environments where children are together, infested children should be treated promptly to minimize spread to others. Regular surveillance by parents is one way to detect and treat early infestations, thereby preventing the spread to others. Treatment. Never initiate treatment unless there is a clear diagnosis with living lice. The ideal treatment of lice should be safe, free of toxic chemicals, readily available without a prescription, easy to use, effective, and inexpensive. Local patterns of resistance if known, ease of use, and cost Table 1 also are considerations when choosing a treatment choice. Published reviews of available efficacy studies and comparative trials of pediculicides have used different inclusion criteria and reached different conclusions.
