Study Description

Brief Summary

Pediculosis capitis is a parasitic infestation that can cause scalp pruritus and quality of life disturbances. There are two objective measurement for pruritus, visual analog scale (VAS) and 5-D itch scale, which can assess the severity of the scalp pruritus and the latter can also asses the quality of life affected by pruritus. Even though VAS can not be used to evaluate the impact of pruritus on quality of life, it is very easy to use while 5-D itch scale is complex and not child-friendly.

The aim of this study is to determine the relationship between two different pruritus scales and to establish validity of pruritus VAS scale in evaluating quality of life in children with pediculosis capitis. We compare two pruritus scale on students with pediculosis of two boarding school in Bogor, West Java, Indonesia.

Pediculus Capitis Pruritus	Other: VAS and 5-D itch pruritus assessment

Detailed Description

This study used cross sectional design study.

Subjects with eligible criteria were included and informed consent from the parents or legal guardian were obtained.

The diagnosis of pediculosis capitis was made based on the findings of eggs, larva, or an adult parasite on the scalp or in the hair of the students. All subjects were asked for both VAS and 5-D itch scale.The VAS is categorized into five groups based on the point, as follows: 0 for no pruritus, <3 for mild pruritus, ≥ 3 - <7 for moderate pruritus, ≥ 7 - <9 for severe pruritus, and ≥ 9 for very severe pruritus. The 5-D itch scale consists of five parameters: duration, degree, direction, disability (sleep, leisure/social activities, housework/errands, work/school), and distribution of the pruritus with points ranging from one to five.

Data were recorded for statistical analysis, a chi-square test was used to determine the relationship between two categorical variables. The correlation coefficient between the VAS and 5-D itch scale was calculated using Spearman's rank correlation
