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.

“…[12][13][14] Furthermore, most pediatric dermatological demodicosis develops when immunity is compromised by administration of steroids, 15 other immunosuppressive agents, 16,17 leukemia, or human immunodeficiency virus. [18][19][20][21][22][23] It is no wonder that most physicians do not consider ocular demodicosis as a cause of blepharoconjunctivitis in healthy pediatric patients.…”

“…The hair follicle mites, Demodex folliculorum and Demodex brevis , are common inhabitants of the human pilosebaceous unit 1,2 . In certain conditions follicle mites increase, and this increased presence probably induces or contributes to skin disorders, such as granulomatous rosacea, papulopustular dermatosis of the bald, pustular folliculitis, blepharitis, and spinulosis of the face 3–5 . We report the case of a patient with onset of demodex folliculitis after phototherapy.…”

“…Overgrowth of the mite caused a condition described as rosacea‐like demodicosis in a recent report of a patient with acquired immunodeficiency syndrome (AIDS) and, in fact, several previous studies have shown large numbers of mites in AIDS patients 5 . Large numbers of Demodex mites have also been found in some other immunodeficiency states, such as leukaemia, but not in patients with psoriasis or undergoing phototherapy.…”

Laugier-Hunziker syndrome (LHS) is a rare disorder characterized by melanotic pigmentation of the mouth and lips which is frequently associated with longitudinal melanonychia. Laugier and Hunziker described lenticular melanotic pigmentation of the oral cavity and lips in 1970. 1 Some cases have been described in which the neck, thorax, abdomen, fingers and soles have been involved. Fingernails are more frequently involved than the toenails. 2 Melanonychia may also be seen with or after lichen planus (LP). 3,4 We report a case of LHS associated with actinic LP.A 37-year-old Turkish woman was referred to our clinic with melanotic macules on the face, a pruritic annular plaque on the malar area of her face and hyperpigmented streaks on her nails, which had appeared for 19 years, 10 months and 6 years, respectively.Examination revealed the patient's pigmented macules on the lips, gums, buccal mucosa and midline of the hard palate ( fig. 1a). There were melasma and pinkish annular plaque, with a hyperpigmented centre ( fig. 1b). There were longitudinal melanonychia on her fingernails ( fig. 1c) and toenails. Hyperpigmented slate-grey to brown macular lesions were seen over her back. Examination of intertriginous areas did not reveal any evidence of acanthosis nigiricans. The skin phototype according to Fitzpatrick's scale was IV.Results of routine laboratory tests were within normal ranges, including triiodothyronine (T3), thyroxine (T4) and thyrotropin (TSH). The patient had smoked for 20 years. Her mother had melasma. Histopathological examination of pigmented macula on the buccal mucosa showed an accumulation of melanin in the cells of the basal layer of the acanthotic epidermis and an increased number of melanophages in the upper dermis ( fig. 2). Histopathologically, there was thinning of the epidermis with vacuolar alteration of the basal layer, an artifactural cleft between the epidermis and the lichenoid infiltrate and pigment incontinence in the upper dermis on the annular lesion over the cheek (fig. 3).Since the first description by Laugier and Hunziker, many cases of LHS have been reported. 2,[5][6][7] In this syndrome, the essential lesions are manifested as lenticular-pigmented macules, which have different colours (from grey to brown to blueblack) and a smooth surface. Generally symptoms are absent. The most common sites are the lips (especially the lower lip) and the oral cavity (buccal mucosa and hard palate). Other sites such as labial comissure, the gums the floor of the mouth and the tongue are less frequent. Other locations such as the abdomen and the fingers have been involved. Fingernail involvement can present as a single longitudinal 1-2-mm-wide streak or as a double 2-3-mm-wide longitudinal streak on the lateral parts of the nail plate, as a homogeneous pigmentation of the radial or ulnar half of the nail, and complete pigmentation of the nail. All four types of nail involvement may simultaneously involve one or more nails of the fingers and /or toes. 2 fig. 1 (a) Multiple pigmented macules lo...
