(Iranian Scientific Society Medical Entomology, 2024) Yildiz, Rahmi; Afsar, Milad; Elasan, Sadi
Background: The main objective of this study is to review publications on the presence of Demodex spp. in patients diagnosed with blepharitis worldwide and to analyse the trends and groups in this field. Methods: This bibliometric study was conducted to detect the presence of Demodex spp. in patients diagnosed with blepharitis worldwide between 1984 and 2023. For this purpose, 288 studies were examined as a result of searches using the keywords "Blepharitis and Demodex" in Web of Science (WOS) databases. All text data was analysed using VOSviewer software to ensure accuracy and reliability. In this study, analysis using text mining and data visualization techniques (bubble maps and graphs) helped to make the results more understandable. Results: This study provided information on 288 articles from WOS databases. The average total number of citations is 1305 and the H-index is 41. The majority of articles (63%) were published in the field of ophthalmology. The countries that published the most articles on this topic were the USA (24%), China (13%), and Turkey (11%). Conclusion: This study is the first bibliometric study of patients diagnosed with blepharitis due to Demodex spp. The most used keyword in blepharitis is Demodex. The most studied field of research is ophthalmology and the most studied country is the United States of America. The results of this bibliometric analysis conducted by us reveal global trends in the presence of Demodex spp. in patients diagnosed with blepharitis and provide important information for future directions of research.
Prevalence and Severity of Demodex Folliculorum and Demodex Brevis Infestation and Their Association With Common Skin Diseases in Northwest Iran
(Iranian Scientific Society Medical Entomology, 2024) Afsar, Milad; Hazrati-Tappeh, Khosrow; Emre-Beyhan, Yunus
Background: Demodex spp., a cosmopolitan mite, can exist as a commensal or parasitic organism. This study aimed to investigate the prevalence of Demodex spp. infestation in patients with common skin diseases and explore the potential association between demodicosis and these conditions in Urmia, northwest Iran Methods: A total of 246 patients attending the Skin Polyclinic of Iranian Urmia Taleghani Hospital were enrolled in the study. Samples were taken from the nose wings, cheeks, and forehead regions of the face area of the persons using the standard superficial skin biopsy method. Results: Demodicosis was detected in 43 (16.3%) patients, with 42 cases attributed to D. folliculorum and 1 case to D. brevis infestation. The highest positivity was found in the 31-50 (21.4%) and 51-72 (22.2%) age groups. In the relationship between demodicosis and skin diseases, Demodex spp. was found in 13 (32.5%) of 40 patients who had skin disease; 6 of these patients with rosacea (42.9%) and 7 with eczema (29.2%). Mite infestation was found in 6 (37.5%) of 16 patients who had hemodialysis due to renal insufficiency. Furthermore, 46.7% of positive patients reported using common goods. The prevalence of demodicosis was similar among patients residing in villages (17.2%) and cities (17.6%). Conclusion: This study sheds light on the potential association between Demodex infestation and common skin diseases such as rosacea and eczema in Urmia, Iran. Therefore, there is a pressing need to augment research endeavors on demodicosis.
