“…These species have been associated as causal agents of demodicosis, cutaneous colonization with nonspecific facial signs and symptoms [1][2][3]. Both species of Demodex represent etiological agents of chronic blepharitis, conjunctival inflammation, and Meibomian gland dysfunction [4]. However, their pathogenic role in healthy people is still controversial.…”

Demodex folliculorum shows a high occurrence in the general population, however, its pathologic relevance is still controversial. In this prospective study, we evaluated the prevalence of D. folliculorum on eyelashes from 8,033 subjects of a university population (including 7,782 students, and 251 academics). Additional information on some risk factors to infection by the mites was evaluated, as well. A prevalence of 1.47% was found, where 118 individuals were positive for D. folliculorum; and, among them, 63 (53.4%) were women and 55 (46.6%) were men. Results showed a negative correlation with the age (r = −0.45), the highest prevalence was found in individuals between 19 and 22 years of age (2.1%, 84 patients). The number of D. folliculorum mites did not differ between the right and left eye; however, the use of cosmetics or facial cream, contact lens, hair removers, were factors present in patients infected with D. folliculorum. Although Demodex prevalence did not increase in line with weight, we found significantly higher prevalence in the 51–60 kg and 71–80 kg weight groups, and a particularly high prevalence in the over 81 kg weight group (2.6%). In conclusion, it was observed that the main population positive to infection consisted of young adults; this is in contrast with the international evidence reporting a high rate of infection in older adults. Besides, our results suggest that items of daily use such as cosmetics, facial cream, eyeliner, glasses, or contact lenses may be some of the main culprits of the infection by D. folliculorum.

Purpose To report a rare non-endemic case of Leishmania aethiopica in Washington DC. Case report A 68-year-old female presented for a routine examination with a complaint of right upper eyelid lesions for the past 5 months. On examination, a cluster of elevated and erythematous lesions extending from the medial canthus to the brow area of the right eye were seen. Initial treatment with Valtrex based on a suspected viral etiology failed. Although a biopsy was recommended at this time, the patient declined, and subsequent workup included nasolacrimal duct irrigation, blood work to rule out autoimmune etiology, a course of doxycycline, and an MRI, which yielded no improvement. Upon progression of the lesions into persistent plaques on the eyelids, a punch biopsy was performed, confirming leishmaniasis. The patient was then started on a 28-day course of oral miltefosine which led to complete resolution of her symptoms. Conclusion This case underlines the importance of a broad differential including non-endemic diseases, particularly in urban areas with frequent patient travel. Furthermore, the delayed punch biopsy in this case highlights the importance of patient counseling to ensure prompt diagnosis and treatment.
