	abstract = {Adults, nymphs and nits of the Pediculus humanus were found in a frame-house infesting the clothes and bedding of three inhabitants in a shanty town in S. Paulo county, S. Paulo State. A total of 198 nits were found glued in 15.0 cm2 of fibres of the infested clothing, giving a ratio of 13.2 nits/cm2. Having in view that the precarious living conditions, promiscuity, absence of basic sanitation and negligence of the sanitary authorities in various Brazilian cities, this situation should not be underestimated. This find should be more frequent than an isolated observation.},

	abstract = {The objective of this study was to compare the prevalence of head pediculosis in the rural and urban environments of Lublin Province (eastern Poland) in 1996-2000 and to examine socioeconomic factors influencing distribution among schoolchildren. A total of 95,153 schoolchildren living in urban and rural areas were examined twice yearly by school nurses. The overall rate of head pediculosis differs significantly between rural (1.59\%) and urban (0.48\%) schools in eastern Poland. Children between 8 and 12 years old were most frequently infested. Pediculosis was observed most frequently in girls both in the urban (63.5\%) and rural (75.3\%) schools and this was related with hairstyles. The prevalence of pediculosis decreased with increasing life standards, i.e. with high income, accessibility and consumption of water and better health care systems. Our findings showed that prevalence of pediculosis capitis depends on the age and sex of the schoolchildren and their living conditions. Hygienic controls of schoolchildren by nurses are important in the elimination of Pediculus humanus capitis. Our results confirmed pediculosis capitis is still a problem in different environments, particularly with lower life standards and poorer economic conditions of health care.},

	abstract = {Since the pioneering work of Charles Nicolle in 1909 [see Gross (1996) Proc Natl Acad Sci USA 93:10539-10540] most medical officers and scientists have assumed that body lice are the sole vectors of Rickettsia prowazekii, the aetiological agent of louse-borne epidemic typhus (LBET). Here we review the evidence for the axiom that head lice are not involved in epidemics of LBET. Laboratory experiments demonstrate the ability of head lice to transmit R. prowazekii, but evidence for this in the field has not been reported. However, the assumption that head lice do not transmit R. prowazekii has meant that head lice have not been examined for R. prowazekii during epidemics of LBET. The strong association between obvious (high) infestations of body lice and LBET has contributed to this perception, but this association does not preclude head lice as vectors of R. prowazekii. Indeed, where the prevalence and intensity of body louse infections may be high (e.g. during epidemics of LBET), the prevalence and intensity of head louse infestations is generally high as well. This review of the epidemiology of head louse and body louse infestations, and of LBET, indicates that head lice are potential vectors of R. prowazekii in the field. Simple observations in the field would reveal whether or not head lice are natural vectors of this major human pathogen.},

	abstract = {BACKGROUND: Approximately 80\% of Argentine children have pediculosis, making it imperious to detect the defects in the prevention and control actions for this parasitosis. OBJECTIVES: To study the infestation level by P. h. capitis, its temporal variation, and the association between infestation and host characteristics. MATERIALS AND METHODS: A monthly census in children of 6-8 years old from 2 primary schools (state and private) was carried out, recording the parasite stages found, children characteristics (sex, colour and length of hair), and infestation level. Data were analysed by means of contingency tables, difference of proportions, quotient of chances, and rank correlation coefficient. The independence of variables was analysed by c{\textquoteright} test. RESULTS: The prevalence and chances of becoming infested were higher at the state school, where also all infestation levels were recorded, which did not occur at the private institute. The frequency of children infested was significantly lower when they had short hair. The correlation among infestation degree and hair length (short-long) was only significant for boys. Pediculosis cases were recorded at the beginning of the school year in both educative institutions, which demonstrated that infestation was acquired not only at school but also at home. CONCLUSIONS: Pediculosis is a social problems and the whole community must participate in preventive and control actions, for which sanitary education is essential, and the myth that the school is the only place of contagion must be eradicated.},
