It is also applied to diagnose bone mineral disorders by taking advantage of the similarity of the structure of keratin and bone collagen. Raman spectroscopy can also be used in dermatology and diabetology. The purpose of the present review is to critically evaluate the available research about the use of Raman spectroscopy in the mentioned areas of medicine. Methodology: PubMed was searched for peer-reviewed articles on the subject of use of Raman spectroscopy in bone mineral disorders, dermatology, and diabetes mellitus. Results: Nail keratin and bone collagen are related structural proteins that require disulfide bond for structural stability. Therefore, Raman spectroscopy of keratin may have potential as a diagnostic tool for screening bone quality and distinguishing patients at risk of fracture for reasons different from low bone mineral density (BMD) in the adult women population. Raman spectroscopy can also investigate the changes in keratin\u2019s structure in nails affected by onychomycosis and distinguish between healthy and onychomycosis nail samples. It could also reduce the need for nail biopsy by distinguishing between dermatophytic and non-dermatophytic agents of onychomycosis. Additionally, Raman spectroscopy could expedite the diagnostic process in psoriasis (by assessing the secondary structure of keratin) and in diabetes mellitus (by examining the protein glycation level). Conclusions: In adult populations, Raman spectroscopy is a promising and safe method for assessing the structure of fingernails. However, data are scarce in the pediatric population; therefore, more studies are required in children.<\/jats:p>","DOI":"10.3390\/medicina60081283","type":"journal-article","created":{"date-parts":[[2024,8,9]],"date-time":"2024-08-09T07:59:07Z","timestamp":1723190347000},"page":"1283","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Is Raman Spectroscopy of Fingernails a Promising Tool for Diagnosing Systemic and Dermatological Diseases in Adult and Pediatric Populations?"],"prefix":"10.3390","volume":"60","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-2139-6464","authenticated-orcid":false,"given":"Teresa","family":"Tabasz","sequence":"first","affiliation":[{"name":"Faculty of Medical Sciences in Zabrze, Students Association, Medical University of Silesia, 41-808 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Natalia","family":"Szyma\u0144ska","sequence":"additional","affiliation":[{"name":"Faculty of Medical Sciences in Zabrze, Students Association, Medical University of Silesia, 41-808 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3793-2771","authenticated-orcid":false,"given":"Katarzyna","family":"B\u0105k-Drabik","sequence":"additional","affiliation":[{"name":"Department of Paediatrics, Faculty of Medical Sciences in Zabrze, Medical University of Silesia, 41-808 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aleksandra","family":"Damasiewicz-Bodzek","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Faculty of Medical Sciences in Zabrze, Medical University of Silesia, Jordana 19, 41-808 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1947-9299","authenticated-orcid":false,"given":"Agnieszka","family":"Nowak","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Faculty of Medical Sciences in Zabrze, Medical University of Silesia, Jordana 19, 41-808 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,9]]},"reference":[{"key":"ref_1","first-page":"779","article-title":"Evaluation of Nail Abnormalities","volume":"85","author":"Tully","year":"2012","journal-title":"Am.
