Abstract:

Introduction: A clinico-mycological study was conducted to assess the profile of dermatophytes and nondermatophytes in patients with superficial mycoses of the scalp. Material and Methods: This descriptive cross-sectional study was conducted at the Department of Microbiology, Basic Medical Sciences Institute, in collaboration with the Department of Dermatology, Jinnah Postgraduate Medical Centre, Karachi. The study was carried out from May 2019 to September 2019. A total of 114 children were enrolled in the study having a clinical diagnosis of superficial mycoses of the scalp. The hair specimens and scales from the scalp were collected by using sterilized forceps and a scalpel on a piece of filter paper. The specimens were processed for wet mounts (KOH and CFW staining) and mycological culture on Sabouraud's dextrose agar (SDA, with and without antibiotics) and Dermatophyte test medium (DTM). Results: The most common clinical presentation was found to be dermatophytoses (28.4%). Non-dermatophytoses was seen in 16.41% of cases, while 55.2% of cases were culture negative. The most common isolated dermatophyte was Trichophyton violaceum (334.35 5.4%), while among non-dermatophyte molds, Aspergillus spp. accounted for 45% of cases. Conclusion: Tinea capitis in children is mostly caused by dermatophytic species but the role of nondermatophytes cannot be neglected the unambiguous diagnosis of scalp mycoses can be made by mycological culture and conventional techniques like KOH mounts and CFW staining. The knowledge of the mycological spectrum of a disease is not only required for clinical management but it also signifies the local disease burden.
