Abstract
OBJECTIVE
Enterobius vermicularis, also known as pinworn, is the responsible agent for Human Enterobiasis. It is one of the most prevalent, but underrated, parasitic disease in children population. Diagnosis involves demonstration of either eggs or adult worms by Graham test. The aim of this study is to describe the clinical, demographic and microbiological features of patients with suspected diagnosis of Enterobiasis in southern Gran Canaria.
METHODS
Descriptive and prospective study of perianal samples evaluated by Graham test in the Microbiology Department of `Insular de Gran Canaria´ University Hospital between November 2014 and November 2015. Descriptive analysis to evaluate the correlation between clinical and demographic variables and the results of Graham test microbiological observation.
RESULTS
1,128 samples were analyzed. E. vermicularis was found in 11.4% of the samples. Among the positives samples, 88.4% belonged to children under 14 years, and 53.5% were male. Abdominal pain (18.6%), anal itching (11.6%), eosinophilia (8.5%) and intestinal parasitosis suspicion (7.8%) were the reasons of parasitological investigation request in positive samples. Nevertheless, a high proportion of the requests was not founded in a suspicious diagnosis or was unrelated to Enterobiasis.
CONCLUSIONS
Enterobiasis is a common disease in primary health care and is of great importance in Gran Canaria. Quality in sample collection as well as diagnosis suspicious information are necessary for a good microbiological analysis.
