Trichoscopy as a Diagnostic Tool for Tinea Capitis: A Prospective, Observational Study

International Journal of Trichology
Pradeep KumarShukla Das

Abstract

Tinea capitis is the most common pediatric dermatophyte infection. Trichoscopy aids in the rapid diagnosis and allows prompt treatment, preventing horizontal transmission. The objective of this study is to document the trichoscopic features of tinea capitis and evaluate its correlation with clinical type, microscopic form, and mycological culture and propose diagnostic trichoscopic criteria. Trichoscopy was performed, after taking consent in 98 participants (<18 years) of tinea capitis diagnose by hair root and scalp scraping examination for hyphae positive on potassium hydroxide mount microscopy or culture positive on SDA media. The comparison of observed trichoscopic features, with the clinical type, pattern of invasion, and etiological agent was carried out. The most common clinical variant was black dot, and etiological agent was Trichophyton violaceum. The following trichoscopic features were noted: black dot, comma, short broken, corkscrew, horse-shoe, zigzag hair, and perifollicular scaling. Perifollicular scaling was significantly common in gray-patch variant, whereas comma, black dot, horse-shoe hair, and perifollicular scaling were noted in black-dot variant. Comma, corkscrew, and zig-zag hair were significantly prese...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
