Insufficiently referenced to meet B class standards. WhatamIdoing (talk) 02:37, 10 October 2008 (UTC)[reply]
The current title of this article -- Pediculosis humanus capitis -- is an unusual choice that I think should be changed. For example, none of the links in the DiseaseDisorder infobox list Pediculosis humanus capitis as a synonym for this disease. The WP:MEDMOS suggests using the ICD10 as a guide which lists for B85.0 "Pediculosis due to Pediculus humanus capitis". While this is precise, I think it's a bit wordy. I think I prefer the listed synonym of "Head-louse infestation". I would even be open to using "Pediculosis capitis", which is mentioned at MedlinePlus. I don't like the idea of using "Head lice" for the disease name because it's also used to describe the animal. Although, I wouldn't be opposed to changing the redirect at Head lice to this article in lieu of Head louse. Noca2plus (talk) 04:21, 10 October 2008 (UTC)[reply]
How can an infestation be a disease? a condition, perhaps? See pediculosis. Julia Rossi (talk) 11:03, 1 December 2008 (UTC)[reply]
. The question of what exactly constitutes a disease is of course a philosophical one, and sometimes the philosophy gets especially tangled if an organism I carry harmlessly might be a health risk for YOU. You bring up typhoid, but there are lots of others. Do the 40% of people who asymptomatically carry meningococcus, have a disease? Are they carriers of a disease, or just a potential disease? And I might easily get traveler's diarrhea if I travel far from home, from the normal GI flora of the people in that country, and vice-versa. So which of us has (or carries) the "disease"? SBHarris 03:35, 13 December 2008 (UTC)[reply]Head lice may cause local infections, but are not a vector for epidemic microbial disease (see below). Head lice per se are a disease only if they cause symptoms. In the absence of discomfort or skin lesions, infestation is therefore only a condition and cosmetic problem for the carrier (not strictly a disease), though they may present a disease-transmission-risk for those others who will develop symptoms, if infected.
The section on The "no-nit" policy now occupies about a third of this article. Although I think school policy with regards to head lice is a notable topic, I think a short summary would suffice in this article about the disease. The balance should be placed in its own article. The title of the new article could be No-nit policy. Although, the text covers issues such as periodic lice screening which are not part of the no-nit policy per se. Perhaps a more general title of School head lice policy is more appropriate with No-nit policy and the like redirecting to that location. Noca2plus (talk) 00:51, 11 December 2008 (UTC)[reply]
The current picture is NOT at all typical and should be removed or changed. 66.36.130.100 (talk) 00:59, 26 August 2009 (UTC)[reply]
(Part of the WikiProject Medicine effort)
This section could benefit by additional references. For example, http://www.hsph.harvard.edu/headlice.html and http://www.cdc.gov/lice/head/factsheet.html are good overall general resources.
I’m not sure what the reference to Figure 5 refers to. This should either be removed or clarified.
There are no references within this section at all. A general medical reference should suffice for an appropriate citation, such as: http://www.cdc.gov/lice/head/factsheet.html#symptoms.
I disagree with the statement: Head lice per se are a disease only if they cause symptoms. There are plenty of diseases that are asymptomatic or have general symptoms that do not distinguish them from others. I recommend this statement be removed.
More references are needed in this section. Again, a citation such as http://www.cdc.gov/lice/head/factsheet.html#transmit would be good. - this has been fixed!
Transmission is a more precise and epidemiological word - great job!
Could further explain what infested means (sentence 1) How much less common is indirect transmission? Great last 2 sentences of the first paragraph. Change "attachment" to "attach" Could indicate what hair diameters they are specific to? Are body lice found on bedding/headwear/combs?
Overall, this is wonderful! Grade reading level is currently at post-graduate, I recommend spending a bit more time with Hemingway Editor to get it down to at least grade 14.
This is made easier by using a magnifying glass or running a comb through the child's wet hair (wet comb method). The wet comb method is the most assured method of diagnosis and can be used to monitor treatment.[34] If there is uncertainty after using the wet comb method, a child can be referred to a health professional. However, head lice infestation is commonly overdiagnosed, with extinct infestations being mistaken for active ones. As a result, lice-killing treatments are more often used on non-infested than infested children.[35]
Simplified language in first sentence above
More references are needed here, such as http://www.cdc.gov/lice/head/factsheet.html#diagnosed.
A general medical text for the steps to perform for diagnosis would provide verification of the protocol written. A good starting point is http://children.webmd.com/slideshow-lice-overview.
What does Figure 4 refer to? Again, clarification is needed.
This section needs to be verified through good citations. The use of rosemary oil requires verification, as well as the sentence on disinfection procedure. See, for example, http://www.diseasesatoz.com/head-louse-home-remedy.htm and http://www.emedicinehealth.com/lice/page4_em.htm.
Here it is mentioned that the adult louse can live 1-2days while the intro mentions 3days and the treatment section mentions 2 days. Need internal consistency.
Here it is mentioned that brushes need to be "left outside" for 2weeks while the treatment section mentions 10min in boiling water. Need internal consistency. — Preceding unsigned comment added by 98.144.87.99 (talk) 04:13, 7 April 2015 (UTC)[reply]
Medications
Resistance to several commonly used treatments is increasing worldwide, with patterns of resistance varying by region. Head lice have demonstrated resistance to permethrin, malathion, phenothrin, and carbaryl in several countries around the world.[24] A previous method used to delay resistance included using a rotating list of insecticides recommended by health authorities. The mosaic model is the current recommendation, in which it is advised to use one product for a treatment course, followed by a different insecticide from another substance class if the first treatment fails.[24]
^looks great! i made a few changes to language above — Preceding unsigned comment added by Cheetah333 (talk • contribs) 18:25, 12 September 2022 (UTC)[reply]
In addition to environmental management, an outbreak of head lice infestation requires treatment of all who are infested at the same time (synchronous treatment) and evaluation of those who have been exposed or are suspected to have head lice. Synchronous ovoidal dimethicone treatment (maybe explain what this is?) has been shown to successfully manage and terminate outbreaks, and a single treatment is likely sufficient. Other treatment methods (such as??) can be repeated 8–10 days following initial treatment, and may sometimes require a third treatment. Outbreak status and treatment effectiveness can be monitored using the wet combing method.[33]
changed the first synchronous treatment to be a lower reading level
if possible explain synchronous ovoidal dimethicone and clarify what other treatment methods are helpful
Additional references are needed in this section, particularly from public health agencies to corroborate statistics. There is some redundancy about lice being more prevalent in girls than boys and lice not known to be disease-causing (in the section on vectorial capacity).
There is absolutely no information here at all. To begin, perhaps this source would be helpful: http://medent.usyd.edu.au/fact/headlice.html.
There is only one section under this heading (school policy); perhaps an expanded discussion on how head lice infestation is dealt with around the world would be appropriate to include here. Please see, for example, http://www.headlice.org/index.html and perhaps some communication with this group would help flush out this section a bit more.
The photo, Hunting lice by candlelight by Andries Both, ca 1630 (National Gallery, Budapest), is only appropriate if the history section or the society/culture section is expanded to discuss how infestation is dealt with outside the U.S.

This text was added
"Ethanol (common alcohol) is toxic in arthropods including lices and of very low toxicity in humans. [1]"
The text translates to
"Cuasia bitter (bitter stick) is extracted from a shrub that grows in northern Argentina . The active substance which is extracted from wood and is chemically quassine is a hydrocarbon soluble alcohol. Popularly it is used as repellent as lice and louse . It is effective not only in alcoholic solution and in aqueous solution. This is as effective as a pure alcohol solution whereby you doubt your pediculicida effect " per se " and is irritative ."
No were in there does it say there is very low toxicity of alcohol in humans? Doc James (talk · contribs · email) 17:00, 3 May 2016 (UTC)[reply]

I am not seeing this text as being supported by the ref

After water, this is probably the next most important solvent used pharmaceutically. Although ethanol (ethyl alcohol) is rarely used as a lone solvent for preparations for internal use, it is used in the manufacture of some of the galenicals used in pharmacy (e.g. tinctures, see Chapter 2). In extemporaneous dispensing it is normally used for the production of lotions for external application to unbroken skin. It is particularly useful if rapid evaporation is required (e.g. for insecticidal lotions applied to hair for the treatment of lice)..."

El principio activo que se extrae de la madera es la cuasina y químicamente es un hidrocarburo soluble en alcohol. Popularmente se lo usa como repelente de piojos y como pediculicida. Es efectiva únicamente en solución alcohólica y no en solución acuosa. Así es tan efectiva como una solución pura de alcohol por lo cual se duda de su efecto pediculicida “per sé” y es irritativa.""
In fact the ref says "when used in products for external use, problems have been encountered because of the volatile nature of the solvent. Asthma attacks have been precipitated... This problem was considered so serious that a number of aqueous formulations were designed"
That is not "harmless".
