Investigation of Demodex Spp. prevalence among managers and workers of health hazard bearing and sanitary establishment.

BACKGROUND/PURPOSE: Two Demodex species are known to live on people. Demodex folliculorum lives in the openings of hair follicles alone or in groups. D brevis lives in the depths of the sebaceous glands alone. There are different related on the epidemiology of Demodex species have been published. METHOD: In this study, taking into account that the parasite is transmitted through close contact from person to person, we aimed to evaluate the relation between the presence of Demodex spp with gender and age among the Health hazard bearing and sanitary establishment operators and workers who came for porter examination. RESULTS: For this purpose, 862 male and 215 female patients with a total of 1077 volunteers from the face area of the standard superficial skin biopsy (SSSB) method and studied samples were taken. More than five mites in 1 cm(2) density was defined as positive. In investigated samples 37.3% Demodex spp. positivity was detected. Only two were found to be D brevis and the others were D folliculorum. The study revealed statistically significant relationships between the positivity of parasites with the occupational group, age and sex. CONCLUSION: Since the prevalence of Demodex among healthy individuals without any complaint was found to be 37%, we believe Demodex spp should be investigated in porter examinations of people who have dermatological complaints.

[Frequency of intestinal parasites among administrators and workers in sanitary and non-sanitary institutions]. / Sihhi ve Gayri Sihhi Müesseselerdeki Isletmeci ve Çalisanlari ve Bagirsak Parazitlerinin Sikligi

OBJECTIVE: Transmission of parasites generally occurs through fecal-oral means directly from human to human or through receiving eggs and cysts by means of nourishment. The aim of the study was to investigate the frequency of intestinal parasites among administrators and workers in sanitary and non-sanitary institutions. METHODS: Stool specimens were examined using native-lugol, Trichrome and acid-fast stains methods. RESULTS: 23.7% of the 2443 fecal specimens were found to be positive. The frequencies of parasites were found to be 9.8% for Entamoeba coli, 7.2% for Blastocystis hominis, 7.2% for Iodamoeba butschlii, 3.4% for Giardia intestinalis, 0.9% for Dientamoeba fragilis, 0.13% for Entamoeba histolytica, 0.08% for Chilomastix mesnilii, 0.04% for Trichomonas intestinalis, 0.04% for Entamoeba hartmanni, 0.04% for Hymenolepis nana, 0.04% for Taenia spp. and 0.04% for Enterobius vermicularis. CONCLUSION: This rate of parasite positivity among healthy subjects visiting hospital for porter examination suggests that intestinal parasites still constitute a public health problem in the region. Moreover, it can be considered that one important factor in the frequency of the parasite can be both the nature of the jobs of administrators and workers in sanitary and non-sanitary institutions and their interaction with people during sales.

[Demodex spp. positivity among laboratory staff, kitchen staff, cleaning workers and nurses working in a state hospital]. / Devlet hastanesi çalisanlarindan laboratuar personeli, mutfak personeli, temizlik isçileri ve hemsirelerdeki Demodex spp. pozitifligi.

OBJECTIVE: This study aimed to determine the prevalence of the types of Demodex spp. among workers in hospitals, where people work collectively in a closed setting for long periods of time. METHODS: In order to determine the parasite prevalence among staff working in the Beydagi State Hospital, including laboratory and kitchen staff, cleaning workers and nurses, defined as risk groups by the infection experts and hospital administration, specimens were collected from their faces using standardized surface skin biopsy (SSSB) and analyzed in parasitology laboratories. Demodex spp. was found in 74.7% of the 95 specimens. The statistical analysis did not reveal any significant differences by jobs, age and gender variables. RESULTS: Moreover, it was observed that positivity was 75.4% for women, and 73.7% for men. Demodex spp. positive staff reported in their histories that they had been diagnosed with rosacea and had pruritus and blushes on their faces from time to time, for which they had not received any medical analyses. Subjects with Demodex spp. were referred to the relevant clinic. CONCLUSION: It was concluded that the high prevalence of the parasite among the hospital staff is associated with inadequate information about Demodex spp. among the staff.
