Lice and Nit Combing Acknowledged as A Valid Treatment Strategy NEWTON, Mass.--(BUSINESS WIRE)--The National Pediculosis Association (NPA) of Newton, Mass. today announced a milestone in its mission to educate parents on chemical-free ways to screen and treat children with head lice. Following review of a citizen petition from the NPA, the U.S. Food and Drug Administration (FDA) has updated its website, Treating and Preventing Head Lice, noting that lice removal kits, which are “comb or comb-like” devices, are a treatment option, and stating that combing may be used alone. “We appreciate the FDA’s careful consideration. While combs have been mentioned passively through the years, the FDA is now recognizing combing as a treatment strategy on its own,” said …
Rickettsia Prowazekii (Epidemic Typhus)
Rickettsia prowazekii is an intracellular, gram-negative coccobacillus. It is an obligate parasite. R. prowazekii belongs to the genus Rickettsia and is the causative agent of epidemic typhus. The genus Rickettsia is composed of gram-negative bacteria. Rickettsiae are the closest known relatives of mitochondria in eukaryotic cells.The vector for epidemic typhus is the human body louse. R. prowazekii multiplies in the gut epithelium of the body louse and explodes into the gastrointestinal (GI) tract, eventually killing the body louse in the process. In this regard, R. prowazekii is unique because no other known members of Rickettsia kill their vector. The R. prowazekii remain viable in the dead louse as well as in the louse feces. Viable R. prowazekii have been detected in dried feces of …
Where Are We With Human Lice? A Review of the Current State of Knowledge
Pediculus humanus is an obligate bloodsucking ectoparasite of human that includes two ecotypes, head louse and body louse, which differ slightly in morphology and biology, but have distinct ecologies. Phylogenetically, they are classified on six mitochondrial clades (A, B, C, D, E, and F), head louse encompasses the full genetic diversity of clades, while body louse belongs to clades A and D. Recent studies suggested that not only body louse, but also head louse can transmit disease, which warrants greater attention as a serious public health problem... Head louse infestation is very common worldwide, especially among schoolchildren, whatever their hygiene status, and the transmission occurs mainly by head-to-head contact. Adults with poor personal hygiene are also commonly …

Severe pediculosis capitis in a nursery school girl
Pediculosis capitis is the most frequent ectoparasitosis around the world. The infestation is caused by Pediculus humanus capitis (head louse), which affects hair, scalp, and skin. It rarely presents with more symptoms and in the majority of the cases, it shows a benign course if treated properly. We present the case of a nursery school girl with head lice infestation for 18 months. She did not improve after the shampoo treatment. This case was associated with furunculosis, skin lesions, multiple adenopathies, and anemia. Initially, the presence of boils, alopecia, and lymphadenopathy was evident. The persistence of pediculosis capitis and intense scratching induced changes on skin integrity, facilitating opportunistic bacterial superinfection that led to impetiginization, furunculosis, …

Head lice can be a pesky problem
"I’m starting to see a few cases of head lice now that kids have been in school awhile. The critters are white and about the size of a sesame seed. They are known as "obligate ectoparasites." Obligate means they require a placental mammal host to survive (i.e. humans) and ectoparasites means they live outside the human body and need a host to survive. They do this by feeding on the host’s blood and can't live off of a body for more than a day or so. Lice are spread by direct contact of a person's head or hair with an infested individual or through sharing personal items such as hats, towels, brushes, helmets, hair ties or even car seat headrests. They do not jump or fly and are not transmitted by pets... Treatment of lice requires a lot of patience. There really is no substitute for …
Kids have allergic reactions to lice treatments
Antihistamines only delay emergency treatment for anaphylaxis Giving antihistamines to children who experience anaphylaxis only endangers their lives by delaying emergency treatment, researchers reported. Instead, children should be administered epinephrine and go straight to the ED. Evan Wiley, MD, a pediatric resident at Jacobi Medical Center in New York, and another colleague reviewed the medical records of children and young adults who were admitted to a community pediatric hospital between July 2015 and January 2019. They found that 72% of patients who first took antihistamines at home delayed seeking medical care compared with only 25% of those who did not take them. Patients who took antihistamines were more than seven times more likely to delay emergency treatment (OR = 7.45; …

The National Pediculosis Association Reminds Parents, School Administrators and Health Professionals To Provide a Non-Chemical Choice on Head Lice For Children, Families, and Yourself! NEWTON, MASS.

They also often have pregnant or nursing mothers who should never be exposed to chemical treatments either by applying them to themselves or to others. Too many people unfortunately overuse chemical agents out of fear and frustration without adequate warning of the risks to themselves and the environment. "Children's exposures to pesticides should be limited as much as possible." https://www.ncbi.nlm.nih.gov/pubmed/23184105/ Each of us has unique vulnerabilities. …
