The NPA Urges the US Food and Drug Administration to Recognize Safer
Head Lice Treatment Choices
"The National Pediculosis Association® (NPA) has submitted a petition to the US Food and Drug
Administration (FDA) requesting that it update its website and other educational materials so that combing with
well-designed nit-removal combs like the LiceMeister® is presented as a safe and effective option for the
treatment of children with head lice. Doing so would give more parents access to the critical information and
guidance necessary to make informed decisions. There are many children for whom a non-chemical treatment
for lice is required." -- Source: National Pediculosis Association.

Insights About Head Lice Transmission From Field Data and Mathematical Modeling
"Head lice infest millions of school-age children every year, both in developed and developing countries. However, little is known about the
number of lice transferred among children during school activities, because direct methods to study this are almost impossible to implement.
This issue has been addressed following an indirect method, which consist in collecting data of real infestation from several children groups
and using a mathematical model of lice colonies to infer how the infestation observed might have evolved.
As part of our experimental study it is also shown that a simple procedure of combing can be very effective to remove all mobile lice, and thus could be used
as an effective preventive measure against those severe infestations that are responsible for the spread of pediculosis." -- Source: PubMed.org.
How a Tiny Insect Was Used to Trace the Origins of Human Clothing
"Almost all mammalian and avian species are host to various species of lice. But humans are among the few species that are host to three (or subspecies). The human head louse (Pediculus humanus capitis), the body louse (P. humanus corporis, also considered P. humanus humanus) and the pubic louse (Pthirus pubis) are obligate ectoparasites to the human body and can’t survive on other species, including pets." -- Source: The Wire.
NPA Petitions FDA to Acknowledge the Benefits of Manual, Non-chemical Approaches and the LiceMeister® Comb for the Care of Children with Head Lice
"The National Pediculosis Association (NPA), a non-profit 501(c)(3) organization dedicated to protecting children and their environment from the misuse and abuse of prescription and over-the-counter pesticide treatments for lice and scabies, announced today that it has petitioned the Commissioner of the Food and Drug Administration (FDA) to amend its website and other educational collateral so that combing, in general, and the FDA-accepted 510(k) LiceMeister® comb, in particular, are presented as valid options for the management and treatment of the communicable disease pediculosis capitis (head lice)."
Fire warning issued over head lice treatments
"A WARNING HAS been issued that head lice treatments can be a fire risk.
The notice was released by the Health Products Regulatory Authority (HPRA) in order to raise awareness about the danger posed by some of the products available in Ireland.
Exposure to a naked flame, any heat source or smoking during use of some head lice treatment products can cause serious injury, the HPRA warn." -- Source: TheJournal.ie.
Should Kids Go to School With Lice?

"A model of the way opinions spread reveals how propagandists use the scientific process against itself to secretly influence policy makers...
...How easy is it for malicious actors to distort the public perception of science?
Today we get an answer thanks to the work of James Owen Weatherall, Cailin O'Connor at the University of California, Irvine, and Justin Bruner at the Australian National University in Canberra, who have created a computer model of the way scientific consensus forms and how this influences the opinion of policy makers. The team studied how easily these views can be distorted and determined that today it is straightforward to distort the perception of science with techniques that are even more subtle than those used by the tobacco industry." -- Source: Massachusetts Institute of Technology - MIT Technology Review.
Response of Pediculus humanus capitis (Phthiraptera: Pediculidae) to Volatiles of Whole and Individual Components of the Human Scalp.
"The head louse Pediculus humanus capitis (De Geer) (Phthiraptera: Pediculidae) is a cosmopolitan human ectoparasite causing pediculosis, one of the most common arthropod parasitic conditions of humans. The mechanisms and/or chemicals involved in host environment recognition by head lice are still unknown. In this study, we evaluated the response of head lice to volatiles that emanate from the human scalp. In addition, we identified the volatile components of the odor and evaluated the attractive or repellent activity of their pure main components. The volatiles were collected by means of Solid Phase microextraction and the extract obtained was chemically analyzed by gas chromatograph-mass spectrometer. Twenty-four volatile were identified in the human scalp odor, with the main compounds being the following: nonanal, sulcatone, geranylacetone, and palmitic acid. Head lice were highly attracted by the blend human scalp volatiles, as well as by the individual major components. A significant finding of our study was to demonstrate that nonanal activity depends on the mass of the compound as it is repellent at high concentrations and an attractant at low concentrations. The results of this study indicate that head lice may use chemical signals in addition to other mechanisms to remain on the host." -- Source: J Med Entomol. 2018 Jan 20..

"Clinically, Paederus dermatitis mimics a host of other dermatose, e.g., herpes zoster, phytophotodermatitis, impetigo, herpes simplex, liquid burn, millipede dermatitis, acute allergic or irritant contact dermatitis, acute eczema, pyoderma. Conventional management of contact dermatitis is recommended: removal of irritant, wash with soap and water, and application of moist bandages. Antibiotics are only used if a secondary infection is present. Oral antihistamines and topical corticosteroids are useful in relieving symptoms." -- Source: Universitas Jember.

pathogens are also a serious problem,

2018 marks 35 years of Service.
The NPA is a 501(c)(3) tax-exempt non-profit volunteer organization, including scientific advisors, dedicated since 1983 to protecting children and their environment from the misuse and abuse of prescription and over-the-counter pesticide treatments for lice and scabies. The LiceMeister comb® was developed by the NPA in 1997 to provide a higher standard for lice combing tools and a safe, cost-effective treatment alternative to pesticides. Proceeds from sales of the LiceMeister comb allow the NPA to be self-sustaining while accomplishing its mission.
