The Epidemiology of Demodex mites at the College Students Living in Dormitories in the City of Ordu

Abstract

ÖZETAmaç: Demodex folliculorum ve Demodex brevis yerleştikleri bölgelerde çeşitli semptomlar verebilmektedirler. Parazitin toplu yaşam yerlerinde görülme yüzdesinin artış gösterebileceği ile ilgili kaynak bilgiler bulunmaktadır. Bu doğrultuda çalışmada yurtlarda kalan üniversite öğrencilerinde demodex türlerinin prevelansının belirlenmesi amaçlanmıştır. Yöntemler: Araştırmanın evrenini Ordu merkezde yurtlarda kalan 300 erkek ve kadın üniversite öğrencileri oluşturmuştur. Örneklem seçiminde rastgele örnekleme yöntemi kullanılmıştır. Çalışmada, gönüllü öğrencilere Hasta Bilgilendirilme Formu doldurulup imzalatıldıktan sonra yüzlerinden standart yüzeysel deri biyopsisi (SYDB) yöntemiyle örnekler alınmış ve değerlendirilmiştir. Bulgular: Yaşları 18-30 arasında değişen 170'i erkek ve 130'u kız olmak üzere toplam 300 üniversite öğrencisinden standart yüzeysel deri biyopsisi yöntemiyle örnekler alınmış ve 110'unda (%37) parazite rastlanılmıştır. Ordu ilinde üniversite öğrencilerinde Demodex spp görülme durumu ile cinsiyet, yaş, cilt tipi, cilt bakım sıklığı arasında anlamlı bir ilişki bulunmamıştır. Sonuç: Sonuç olarak parazitin enfestasyon oranı Ordu'daki üniversite öğrencilerinde yaygındır.

There are indications showing that the prevalence of these parasites is higher in public places. In this direction, the study was aimed to determine the prevalence of demodex in university students, inhabiting in dormitories. Methods: The study consisted of 300 men and women, college students who were staying in the dormitories in the city of Ordu. Random sampling method was used in the sample selection. Each participating student had to sign a patient's consent form, before samples were taken using standard superficial skin biopsies from the faces of the patients. The samples were embedded in Entellan mounting solution and examined under the light microscope.Results: Samples were taken from 300 college students (170 males and 130 females) aged between 18-30 years, and in 110 (37%) of them, demodex mites were found. No significant differences were found between gender, age, type of skin or skin care, and Demodex incidence. Conclusion: Demodex mites are very prevalent in college students studying in Ordu.

The effect of skin moisture,pH, and temperature on the density ofDemodex folliculorumandDemodex brevis(Acari: Demodicidae) in students and staff of the Erzincan University, Turkey

“…Although Demodex mites can be found in the skin of healthy persons without creating any pathogenic effect, they could become opportunistic pathogens if the immune system of the host is suppressed . The prevalence of Demodex mites in healthy controls in other studies, which were conducted in Turkey, varied between 7 and 74.7%, while the mite density varied between 0.97/cm 2 and 2.86/cm 2 . In several studies conducted abroad, the prevalence of Demodex mites in healthy individuals was similar to those in this study, lower, or higher, while the mite density was lower than in this study .…”

“…In the present study, more men were infested with Demodex mites than women, though the differences were not significant. While some studies also showed that Demodex prevalence is higher in men than women, in other studies the prevalence was higher in women or equal among men and women …”

The Investigation of Prevalence of <i>Demodex</i> spp. in University Students: The Case of the Faculty of Health Sciences

“…Türkiye'de yapılan çalışmalarda Demodex spp. pozitifliği ve pozitifliğine etki eden faktörler farklı gruplarda değerlendirilmiştir (1,(5)(6)(7)(8)(9)(10)(11). Gençlerde ergenlik döneminde akne vulgaris en sık rastlanılan deri problemlerinden biridir.…”

O014. The diagnostic mistake: when the patient reports pain affecting eyes and benzodiazepines abuse without any glaucoma or any apparent organic cause

“…Demodex -type A and type B-, the most serious non-neoplastic dermatological disease [ 2 , 3 ], is not so widely known in human pathology [ 4 ]. This ascaris provokes discomfort and pain, the severity of which depends on the extent and seriousness of the disease [ 2 – 4 ], as well as on the pain proneness evidenced in third hyperalgesia test we proved several years ago [ 5 ]. Thus, pain proneness and pain redundancy might be present in both migraine sufferers and in their relatives.…”
