Nonfluorescent tinea capitis in Charleston, SC. A diagnostic problem. 1979

E Prevost

Statistics gathered at the Medical University of South Carolina from 1973 to 1978 indicate a dramatic change in the etiologic agents of tinea capitis in Charleston since the 1950s. The preponderant agent is now Trichophyton tonsurans, which produces lesions that are not fluorescent in a Wood's lamp examination (long-wave ultraviolet). Trichophyton tonsurans caused 90.6% of 265 culture-proved cases of tinea capitis in the 1970s, but in the 1950s it was responsible for only 1.6% of 378 cases. The study emphasizes that cultures are necessary because the increase in nonfluorescent tinea capitis throughout the United States presents unsuspected diagnostic problems to physicians who are not aware of the change in etiologic agents.

UI	MeSH Term	Description	Entries
D005453	Fluorescence	The property of emitting radiation while being irradiated. The radiation emitted is usually of longer wavelength than that incident or absorbed, e.g., a substance can be irradiated with invisible radiation and emit visible light. X-ray fluorescence is used in diagnosis.
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D013022	South Carolina	State bounded on the north by North Carolina, on the east and south by the Atlantic Ocean, and on the west by Georgia.
D014006	Tinea Capitis	Ringworm of the scalp and associated hair mainly caused by species of MICROSPORUM; TRICHOPHYTON; and EPIDERMOPHYTON, which may occasionally involve the eyebrows and eyelashes.

D014249	Trichophyton	A mitosporic fungal genus and an anamorphic form of Arthroderma. Various species attack the skin, nails, and hair.	Endodermophyton,Trychophyton,Endodermophytons,Trichophytons,Trychophytons
D014466	Ultraviolet Rays	That portion of the electromagnetic spectrum immediately below the visible range and extending into the x-ray frequencies. The longer wavelengths (near-UV or biotic or vital rays) are necessary for the endogenous synthesis of vitamin D and are also called antirachitic rays; the shorter, ionizing wavelengths (far-UV or abiotic or extravital rays) are viricidal, bactericidal, mutagenic, and carcinogenic and are used as disinfectants.

Race and ethnicity terms, as used in the federal government, are self-identified social construct and may include terms outdated and offensive in MeSH to assist users who are interested in retrieving comprehensive search results for studies such as in longitudinal studies.
