Dec 14 DDT In Alaskan Fish Exposes Children, As Well As Adults, To Higher Cancer Risks
"According to new reports, Alaskan fish is presenting high levels of DDT and other insecticides, exposing both children and adults to higher cancer risks. As for the children living in by the Eastern Alaska Mountain Range, whose diet is mainly composed of fish, the threat is higher as even small amounts of DDT and hexachlorocyclohexane boosts the risks of cancer, as reported by Lab Manager. The DDT and organochlorine pollutants (OCPs) reach in the fish’s bloodstream via glacial meltwater which absorbed these chemicals over the time. According to Kimberley Miner, research assistant professor at the University of Maine Climate Change Institute, the risks of cancer due to DDT, organochlorine pollutants (OCP), and hexachlorocyclohexane is higher in children who consume contaminated fish than it is in adult populations." -- Source: Health Thoroughfare.
Nov 26 Lindane, kepone and pentachlorobenzene: chloropesticides banned by Stockholm convention
"Persistent organic pollutants are a serious problem to the environment due to their toxicity to both fauna and flora. Extremely resistant to biodegradation and prone to transfer through long distances via atmosphere can contaminate almost any place in the planet. They tend to bioaccumulate in fat tissue due to their lipophilicity and seriously affect poisoned organism’s nervous, hepatic, reproductive or hormonal system. Since 2009, due to the Stockholm convention on persistent organic pollutants production and utilisation of certain halogenated pesticides has been prohibited.

Sep 6 Going to School with Carefully Combed Hair Takes on New Importance!
"September is National Head Lice Prevention Month: A Time to CombFirst! This fall, there is one more important reason for children to leave for school every day with their hair carefully combed. As schools relax their vigilance and allow children with head lice into the classroom, the nonprofit National Pediculosis Association (NPA) is urging parents to proactively use a quality lice and nit removal comb for early detection, so an infestation doesn’t catch them by surprise. The CombFirst! message is central to a year-long educational campaign sponsored by the NPA, which kicks off each September as National Head Lice Prevention Month. The NPA is a nonprofit organization that is dedicated to setting the highest possible public health standards, with a specific focus on protecting children and their families from lice and associated risky chemical treatments.

May 23 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."

Feb 22 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."

Feb 18 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."

Feb 8 NPA petitions FDA on management of pediculosis with safe combs rather than chemicals
"Currently, the FDA emphasizes chemical treatments for children with head lice and refers to these treatments by brand name. By contrast, lice and nit removal combs are referred to only briefly and generically, without attention to the proven methods and benefits of combing or the fact that all lice combs are not equivalent."

Jan 26 The tricks propagandists use to beat science.
If one wonders how new school lice policies get written without a scientific basis and accepted read here:

"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."

Jan 20 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."

"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."

Jan 1 Nanopore sequencing Rapid, real-time pathogen identification and antimicrobialresistance profiling.
"Whether airborne or present in food and water supplies, pathogens have the potential to affect agriculture and human health profoundly. Livestock infectious diseases can have an influence on animal welfare and global food production1 . Crop pathogens are also a serious problem, especially in agriculture-based economies. Rice infection with Magnaporthe oryzae can have devastating effects on yearly yields2 . Furthermore, as recent Ebola and Zika outbreaks have reminded us, pathogens pose a significant threat to public health, and a challenge for modern medicine. Widespread and increasing drug resistance of infectious organisms compounds this threat. "
