Andrea Exnerová Enterobius vermicularis Bachelor thesis Charles University in Prague, Faculty of Pharmacy in Hradec Králové Medical laboratory technician Background: The aim of this thesis is to create an overview of the current knowledge about Enterobius vermicularis and to perform a questionnaire study among parents. The aim of this survey is to find out informations about the progress, diagnosis and treatment of this infection and public awareness of this disease. Methods: Questionnaire study among parents, whose children have ever been infected with Enterobius vermicularis. Results: Pinworm infection is the most common among children aged 4-7 years. Half of the children who visited a pediatrician were examined. In almost 25 % of the cases, the stool sample was collected. The children were treated mostly with prescribed medication, the parents rarely chose home-treatment. In one third of the cases, the other members of the household were infected too. In the half of the cases the whole family was treated preventively. The most common symptom is rectal itching (83 %). Complications are exceptional. 60 % of the respondents incorrectly think that it is possible to get infected with pinworms from animals. The respondents most commonly called enterobiasis a disease of dirty hands. Conclusions: The...

Present occurence of Enterobiasis in chldren
BREUOVÁ, Dora
Enterobius vermicularis (pinworm) is one of the most common nematodes in the world.Adult worms multiply in the large intestine. Gravid female pinworms migrate to the rectum, where they lay eggs on the skin around the anus.The disease caused by pinworm is called enterobiosis. Small children specially are suffering from this disease. There is no association with world areas or social groups. Enterobiosis is transmitted by faecal-oral route. Eggs are transmitted either through contaminated hands or objects or even dust can contain pinworm eggs. Enterobiosis is usually asymptomatic. However, sometimes there is itching in the anal area, insomnia, discomfort and enuresis and also there could be further complication such as acute appendicitis. Rarely, but in women pinworm can move into the vagina and from there further to uterus or also to the urinary tract. In this case pills Mebendazoland, Thiabendazol are used as a treatment.The goals of this thesis were: 1) To examine representative group of children by Graham method to determine prevalence of enterobiosis. 2) To compare the results with past results which were recorded in the Czech Republic.3) To compare the results with results published elsewhere. In total 113 children were examined from 3 infant schools. Children were in age between 3-7. Nine out of those children were from village and the rest of them were town children. Samples had been collected in the period of time May 2012 - March 2013. Parents of those children gave permission for examination. Samples were taken by Graham method, also called ,,Cellophane tape test?? which is simple and cheap.Transparent adhesive tape was applied and pressed to perianal area of the child several times. Afterward the tape has been attached to microscope slide, marked by pertaining number and put into the plastic box before observation. Those samples were observed using the light microscope Olympus CX 21. Objective 10x has been used to scan the slide and find eggs of Enterobius vermicularis and objective 40x for confirmation of egg determination. To find eggs of Enterobius vermicularis object-lens 10x was used.To check positivity when eggs were found I used lens 40x.Five samples out of 113 samples of examinated children were positive on presence of enterobiosis. The total prevalence was 4,4%. Age and sex were considered. Three out of five positive samples came from boys and two from girls. One of the boys was age 4 and two age 6. Girls were of age 4 and 5. The level of significance (P>5%) confirmed that there was no difference among children aged depending on the disease. Difference between sexes was not been confirmed. From a previous study was found out that differences between adults and children were not big at all and statistically were not confirmed that adults suffering from enterobiosis is lass than children suffering from this disease. It is hard to confirm that there is no relation between age and spreading this disease because we there are not enough studies on this subject. The cases where adult became ill with enterobiosis were predominately caused by transmission of the infection from children that obtained enterobiosis in the school and then infected family members. Studies focused on occurrence children enterobiosis took place in the Czech Republic in 70´s. My results were compared with results from those studies. The prevalence was compared at a time and displayed in a graph. I found out that prevalence decreased 10-20 times. From foreign studies the prevalences in European and Asian states were taken and compared with others in the chart. Assumption was, that prevalence in Europe will be lower than in Asia. From my statistics had been demonstrated that the prevalences of this disease is equal in both areas. However the groups of examined were different in each state, which means that results cannot be statistically compared.
