We examined the infestation rate of head and/or body lice in patients in a mental hospital, Seoul, Korea on June 27-28, 1988. Of 438 women, 146 (33.3%) were positive with nits or worms of louse. Of 143 men, 22 (15.4%) were positive with those of louse. Regular control programs were necessary to this hospital.

BACKGROUND In the treatment of human head lice infestation, healthcare providers are increasingly concerned about lice becoming resistant to existing pesticide treatments. Traditional pesticides, used to control these pests, have a neurological mechanism of action. This publication describes a topical solution with a non-traditional mechanism of action, based on physical disruption of the wax l...

Head lice (Pediculus humanus capitis) infestation is an important disease worldwide, especially in children under 11 years old. Permethrin is the most common insecticide for treatment of human pediculosis, but nowadays resistance to permethrin and other pyrethroids has caused many treatment failures. The second treatment of choice is malathion.

BACKGROUND Head lice most commonly affect children, ages 3 to 11. Concerns exist about the safety and efficacy of pesticide-based treatments. Published studies suggest dimethicone is a potentially safe and effective non-toxic treatment, but have not evaluated 100% dimethicone in a pediatric population. The objectives were to evaluate the efficacy and safety of 100% dimethicone for the treatment...

The hair samples of Ferdinand II of Aragon (1467-1496), King of Naples, whose mummy is preserved in the Basilica of San Domenico Maggiore in Naples, showed a high content of mercury, with a value of 827ppm. Furthermore, examination using a stereomicroscope and a scanning electron microscope (SEM) of head and pubic hairs of Ferdinand II, revealed a lice infestation. The reasons for the massive p...

Background Head lice, a common social and health problem among all age groups, is especially widespread among school-aged children. Aims This study aimed to assess the prevalence of pediculosis capitis among governmental primary school students in Southern Jordan and its related risk factors. Settings and Design A sample of 500 primary schools students aged 6-12 from two male and two female...

This descriptive, analytical study was carried out in 2003 to determine the prevalence of pediculosis capitis and some risk factors among primary-school pupils in Kerman. We selected 1200 pupils (53% girls) from 50 primary schools by multistage, systematic random sampling. Their hair was examined for head louse infestation: 45 (3.8%) were infected with lice, 43 (95.5%) girls and 2 (4.5%) boys. ...

The possibility of spreading by migration, colonizing new spatial domains suitable for development and reproduction, can substantially relieve a biological population from the risk of extinction. By means of a realistic computational model based on empirical data, we study this phenomenon for the human head louse, Pediculus humanus capitis. In particular, we show that a lice colony infesting a ...

  Background: Head louse infestation is highly common in collective centers such as schools, garrisons and campuses. This study was done to determine the prevalence and risk factors associated with Pediculus humanus capitis in primary school girls in Qom Provincecentral Iran. Materials and Methods: This descriptive –analytic study was conducted among 1,725 feminine primary students from 89 sch...
