Abstract

Contact lenses are the most popular devices used by many people around the world for vision correction, aesthetics, and therapeutic purposes. Poor contact lens hygiene can cause various complications. One of the concerns regarding the use of contact lenses is the presence of Acanthamoeba spp. Acanthamoeba spp. is a free-living amoeba that can be found in many places including untreated fresh water, treated fresh water and unconventional water sources. One of the complications caused by Acanthamoeba spp. is Acanthamoeba keratitis which is an eye infection that is often caused by the use of contact lenses and contaminated contact lens solutions. Objective. The purpose of this study is to determine the description of Acanthamoeba spp. found in contact lens solution and contact lens care of Universitas Sumatera Utara students. Method. This study used univariate analysis. Data were obtained from the results of contact lens solution examination and questionnaire interviews. Result. Most of the samples (98%) did not have Acanthamoeba spp. Some respondents (60.8%) had fairly clean contact lens care behaviour and the rest (39.2%) had very clean contact lens care behaviour. Conclusion. One sample was found positive with Acanthamoeba spp. The positive sample had Acanthamoeba spp. cyst. Contact lens care was generally done well.

Abstract

Background: Soil-transmitted helminths (STH) infection is currently one of the highest prevalence neglected tropical diseases in children. Factors contributing to such case are children’s hygiene, as well as the existence of helminths in the surrounding soil. Objective: Therefore, this research is done to determine whether there is significant association between hygiene and STH infection in children. Methods: This observational analysis with a cross-sectional design was conducted on elementary school children by interviewing the children and obtaining fecal samples. Results: Analysis of 197 fecal samples shows that 14.7% of the children were infected with STH and results of the interview show more children had poor knowledge about STH infection (69%). Good hygiene attitude and behavior were found in the majority of the subjects (58.9% and 81.7% respectively). The chi-square analysis performed shows no significant relation between knowledge (p=0.626), attitude (p=0.975), and behavior (p=0.376) and the incidence of STH infection. Conclusion: In this study, although children demonstrated poor knowledge of STH infection but had good hygiene attitudes and behaviors, there was no significant link between these factors and STH infection. This emphasizes the need for ongoing hygiene education in elementary school children.
