| [pediculosis capitis, a permanent and renewed problem]. | pediculosis capitis is still a world-wide public health problem. pediculus humanus capitis, the agent, is a permanent and specific human blood-sucking ectoparasite extended throughout the world. by the end of sixties and begin of seventies an important increase of prevalence of this parasitose was observed in many countries and lice infestation throughout the world was estimated to run into hundreds of millions. decline of personal hygiene, increased promiscuity and long hairstyle, particularly ... | 1997 | 9640684 |
| the prevalence of pediculus humanus capitis among the students of a secondary and three elementary schools in karsiyaka-izmir, turkey. | during november-december 1993, 5347 students of a secondary and 3 elementary schools in bostanli-karsiyaka, where socio-economic and cultural status are relatively high, were examined for pediculosis capitis. in 225 students (4.2%) eggs and/or adults were detected. 181 (4.14%) out of 4365 elementary school students and 44 (4.48%) out of 982 secondary school students were infested with pediculus humanus capitis. comparison with results of previous results are shown in the text. | 1997 | 9097537 |
| adaptive sex-ratio manipulation in pediculus humanus capitis: possible interpretations of buxton's data. | the sex-ratio pattern of an exceptional population of human head lice (collected in the colombo prison, ceylon, in 1934 to 1936) was found to be consistent with a current hypothesis on adaptive sex-ratio manipulation. data suggest that the louse burdens were isolated and, therefore, small burdens were inbred. thus, local mate competition favored females that produced offspring with a female bias. this is the first report to suggest that anopluran lice are capable of adaptive sex-ratio manipulati ... | 1997 | 9194847 |
| can house dust mite-triggered atopic dermatitis be alleviated using acaricides? | house dust mite (hdm) allergens are the most important triggers for atopic dermatitis. reducing exposure to these allergens may alleviate clinical symptoms. chemicals with acaricidal activity have been used to treat upholstered furniture, carpets and bedding with the aim to reduce hdm allergen exposure. these chemicals, by reducing hdm, can decrease the concentration of mite allergens in dust but improvements in clinical symptoms are not always apparent. clinical improvement is more likely to oc ... | 1997 | 9274618 |
