Treatment of ectoparasitic infections: review of the English-language literature, 1982-1992.
We reviewed the English-language literature of 1982-1992 for papers concerning scabies, pediculosis, and their treatments; this information was supplemented with opinions of workers in the field of ectoparasitic disease. Six treatment trials for scabies, one study of the treatment of pediculosis pubis, and additional studies on the treatment of pediculosis capitis were included. Both lindane 1% and permethrin 5% are effective treatments for scabies, although resistance to lindane does exist. Lindane 1%, permethrin 1%, and pyrethrins with piperonyl butoxide are all effective treatments for pediculosis. Severe reactions to lindane therapy may occur when increased skin absorption of lindane occurs. Permethrin 5% or lindane 1% is recommended for the treatment of scabies. Lindane should be used with precautions to avoid excess skin penetration and should not be used to treat infants, young children, or pregnant or lactating women. Permethrin 1%, lindane 1%, or pyrethrins with piperonyl butoxide is recommended for the treatment of pediculosis pubis. Pregnant and lactating women should be treated with either permethrin or with pyrethrins containing piperonyl butoxide.
Parasitic infections and maternal awareness of preschool children in Karmouz district, Alexandria.
Intestinal parasitic infections are widespread especially among preschool children living in poor areas. Also pediculosis has been perceived as a public health nuisance for decades. A cross-sectional study was conducted on 256 children and their mothers in a poor urban district to assess mothers' knowledge and practices as regards parasitic infections and infestations that may be present in her preschool child, and to correlate the presence of these infections with her awareness. A pre-designed questionnaire that included socio-demographic data, items to assess mothers' knowledge of sources and preventive measures of parasitic infections and infestations and her practices was completed. A stool sample was collected from children and examined using formol-ether technique and Sellotape technique was used to detect Enterobius vermicularis. Pediculus capitis was diagnosed by inspection of the scalp and was found to be the most prevalent parasite found in 58.9% of those children followed by Enterobius vermicularis in 46%. A strong positive association between pediculosis and enterobiasis was detected (phi coefficient = 0.956, p < 0.001). Socioeconomic level affected both knowledge and practices scores where one point change in knowledge score or socioeconomic score caused an increase in practice score of 0.279 and 0.071, respectively. Also higher risk of pediculosis was found to be significantly associated with female sex and low socioeconomic level. An increase of one point in practice score showed a decrease in the log likelihood ratio of enterobiasis of 14.3%. The majority of mothers (77.3%) were found to be aware that their children had a parasitic infection, which was significantly associated with results of stool analysis. This indicates that awareness building is not enough to be of practical benefit. Appropriate and detailed control methods of parasitic infections and pediculosis must be taught and applied by parents and community. Socio-economic development, organized health programs and motivation should be undertaken to help today's children.
Some lousy questions for home health nurses.
Pediculosis continues to be a widespread problem for both the public and health care professionals, including home health nurses. Dealing with this problem is complicated by a number of factors, including questions concerning the efficacy and safety of the medications used and the level of knowledge of about this condition. Because pediculosis often is considered more as an embarrassing annoyance than a serious threat, it has a relatively low priority on the list of contemporary health care concerns. This article addresses several practical questions concerning the character and treatment of pediculosis that are of special concern to home health nurses.
Head lice are not found on floors in primary school classrooms.
BACKGROUND: The control of head lice is frequently based on perceptions rather than evidence, as illustrated by the belief that vacuuming carpets is an essential component of treating head lice, and the less common practice of application of insecticides to floors as an adjunct to head lice treatment. OBJECTIVE: To 1) evaluate the importance of floors as a source of infection for head lice in primary schools to provide evidence on which to base decisions about the need to treat floors; 2) determine the prevalence of active pediculosis and average intensity of infection in primary school children in Townsville, north Queensland. METHODS: In Townsville, north Queensland, we examined preschool and primary classroom floors for lice by using a filter on a vacuum cleaner when the children were absent from the rooms. Active pediculosis was treated, head lice were collected and counted. RESULTS: Of the 2,230 children examined from 118 classrooms, 466 had head lice, a prevalence of 20.9%. A total of 14,033 lice were collected from these children to give an average intensity of infection of 30.1 (95% CI 21.9-38.3) lice per infected child and 129.9 (95% CI 90.7-169.2) lice per infected class. Of the 118 classrooms, 108 (91.5%) had at least one child with active pediculosis. No lice were recovered from the classroom floors. CONCLUSION: Classroom floors are not a risk in the transmission of head lice and no special anti-louse measures are required.
Household exposure to pesticides and risk of childhood acute leukaemia.
OBJECTIVES: To investigate the relation between childhood acute leukaemia and household exposure to pesticides. METHODS: The study included 280 incident cases of acute leukaemia and 288 controls frequency matched on gender, age, hospital, and ethnic origin. The data were obtained from standardised face to face interviews of the mothers with detailed questions on parental occupational history, home and garden insecticide use, and insecticidal treatment of pediculosis. Odds ratios were estimated using unconditional regression models including the stratification variables parental socioeconomic status and housing characteristics. RESULTS: Acute leukaemia was observed to be significantly associated with maternal home insecticide use during pregnancy (OR = 1.8, 95% CI 1.2 to 2.8) and during childhood (OR = 1.7, 95% CI 1.1 to 2.4), with garden insecticide use (OR = 2.4, 95% CI 1.3 to 4.3), and fungicide use (OR = 2.5, 95% CI 1.0 to 6.2) during childhood. Insecticidal shampoo treatment of pediculosis was also associated with childhood acute leukaemia (OR = 1.9, 95% CI 1.2 to 3.3). CONCLUSION: The results reported herein support the hypothesis that various types of insecticide exposure may be a risk factor for childhood acute leukaemia. The observed association with insecticidal shampoo treatment of pediculosis, which has never been investigated before, requires further study.
Survey of infectious skin diseases and skin infestations among primary school students of Taitung County, eastern Taiwan.
BACKGROUND: There are no complete records on the prevalence of childhood skin diseases in Taiwan. We conducted a survey of infectious skin diseases and skin infestations among primary school children in Taitung County, which is located in southeastern Taiwan. METHODS: From March 1998 through October 1998, a total of 3,029 students from four rural districts (Changbin, Yanping, Lanyu, and Dawu) and one urban area (Taitung City of Taitung County) were examined by dermatologists. Treatment and instructions for disease care were given immediately after the diagnosis of dermatoses, when appropriate. RESULTS: The most common infectious skin diseases and infestations were pediculosis capitis (12.9%), verruca vulgaris (5.1%), tinea versicolor (4.4%), tinea pedis (4.1%), verruca plantaris (1.8%), and scabies (1.4%). Most skin diseases, including pediculosis capitis, scabies, verruca vulgaris, verruca plantaris, folliculitis, pyoderma, tinea pedis, and tinea versicolor, were significantly more common in rural areas than in the urban area (p < 0.05 for all). Pediculosis capitis was more common among girls (p < 0.001), but tinea pedis and tinea versicolor were more common among boys (p < 0.05). CONCLUSIONS: The prevalence of most skin infections and infestations are much higher in rural Taitung County than in Taitung City. Prevention and treatment of these skin diseases should be reemphasized in the education of teachers, as well as students and their families. Adequate dermatologic training of nurses and physicians and the development of teleconsultation and teledermatology in rural areas might decrease the prevalence of these skin diseases in school children.
Prevalence and treatment of Pediculus humanus capitis with 1% permethrin and 0.4% d-phenothrin in Turkey.
Pediculosis humanus capitis (head lice) is an important public health problem among school children. In our study, 20,612 schoolchildren (10,367 boys, 10,245 girls) were examined for Pediculus humanus capitis in 36 elementary schools between December 1996 and February 1998 in Ankara, Turkey. The prevalence of pediculosis capitis infestation was found to be 3.4% (701/20,612). Of these, 382 students were treated with application of 1% permethrin cream rinse, and 184 students with 0.4% d-phenothrin shampoo. On day 14 of the controlled trial, the success rates were 93.7% in the 1% permethrin cream rinse group and 75.5% in the 0.4% d-phenothrin shampoo group. The 1% permethrin cream rinse was also significantly more active in pediculicidal efficacy when compared to the 0.4% d-phenothrin shampoo (p<0.001). As a result, these findings demonstrate that pediculosis capitis still remains a widespread health problem.
