Presentation
We highlight the presentation, treatment, and underscore demodicosis as an important, under recognized cause of blepharitis. [ncbi.nlm.nih.gov]
Demodex mites were present in the infundibulum of several hairs. [wildpro.twycrosszoo.org]
Entire Body System
- Recurrent Inflammation
During a follow-up period of 8.3 ± 4.6 months, 1 patient showed recurrent inflammation, which was successfully managed by a second round of TTO treatment. [ncbi.nlm.nih.gov]
Skin
- Partial Alopecia
Crusty skin lesions and flaking scales ( J15 .21.w1, B284 .6.w6, B291 .12.w12) BEARS In a female Ursus americanus - American black bear from northern Wisconsin, partial alopecia and scabs. ( J1 .14.w9) Five of 70 live-trapped bears were noted to have [wildpro.twycrosszoo.org]
- Skin Thickening
Facial skin of the affected areas was noted to be erythematous, thickened, and had small follicular papules. [wildpro.twycrosszoo.org]
Psychiatrical
- Fear
Evidence of phobia should, provisionally, be labelled with the nonperjorative term symbiophobia (herein coined for "fear of association with organisms"), and the causative organisms, if present, treated. [ncbi.nlm.nih.gov]
Workup
HLA Type
- HLA-A2
Individuals who have the HLA A2 phenotype are 2.9 times more resistant to demodicosis. A positive correlation between demodicosis and the haplotypes A3-Cw4, A3-Cw2, A3-B17, A3-B35 and B35-Cw4 was found. [ncbi.nlm.nih.gov]
Treatment
Eyelid scrubs or massage with TTO could be an effective treatment regimen in these cases. [ncbi.nlm.nih.gov]
Etiology
The usual etiological agent of primary demodicosis is D. folliculorum, which causes an erythemato-squamous eruption in the facial T-zone. The rash starts on unaltered skin and covers 8 - 15 % of the face. [ncbi.nlm.nih.gov]
All causes leading to immunocompromisation are generally due to etiological factors [ 15 ]. For immunocompetent patients, oral sex (fellatio) may be the primary cause [ 16 ]. [doi.org]
Epidemiology
METHODS: We conducted a prospective epidemiologic study among 10 dermatologists. High Demodex density (Dd) was confirmed by standardized skin surface biopsy. [ncbi.nlm.nih.gov]
Epidemiology Frequency International Several individuals have attempted to estimate the prevalence of D folliculorum in the eyelash follicles. [emedicine.medscape.com]

Prevention
Hence, demodicosis may be seriously considered in antibiotic-resistant facial papulopustular eruptions in this group of patients to prevent delay of adequate treatment. [ncbi.nlm.nih.gov]
Ether and alcohol should be used with caution, and corneal contact should be prevented. A combination of this in-office treatment with a home regimen is suggested. [emedicine.medscape.com]

Home treatment and prevention strategies include: Using mild shampoo on hair and eye lashes every day Cleansing the face twice daily with a non-soap cleanser Avoiding oil-based cleansers and greasy makeup Exfoliating periodically to remove dead skin cells [dermnetnz.org]
