Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Introduction:

* Tinea capitis is a superficial fungal infection of the skin of the scalp, with a propensity for attacking hair shafts and follicles . The disease is considered to be a form of superficial mycosis or dermatophytosis
* It may affect all or part of the child's scalp.
* Mold-like fungi called dermatophytes cause tinea capitis ,It is caused primarily by Dermatophyte species Microsporm and trichopyton,, In Egypt, dermatophytes called Microsporum canis and Microsporum audouinii are the most common causes of the infection. Fungi thrive in warm, moist environments. It commonly grows in tropical places.
* Tinea capitis can be divided into inflammatory and non-inflammatory types, the non-inflammatory type usuallywill not be complicated by scaring alopecia , the inflammatory type may result in Kerion ,a painful nodule with pus and scaring alopecia, The clinical manifestations of tinea capitis are classified as endothrix, ectothrix, or favus. In the endothrix form, hyphae grow down the follicle and penetrate the hair shaft, then grow completely within the hair shaft. This form is caused predominantly by T. tonsurans and T. violaceum In the ectothrix form, the hyphae invade the hair shaft at mid follicle. Afterwards, hyphae grow out of the follicle covering the hair surface. This form is caused by M. canis, M. audouinii, Microsporum ferrugineum, and Trichophyton verrucosum. The hyphae grow parallel to the hair shaft in favus form then degenerate, leaving long tunnels within the hair shaft. Favus form is caused by Trichophyton schoenleinii and is characterized by yellow crust around the hair shafts and can result in permanent scarring alopecia.
* ♦ Tinea capitis also spreads very easily. The patients can catch the infection from contact with infected people, animals and soil. They can also get it by using objects and touching surfaces that harbor the fungus. Tinea capitis can live for a long time on infected objects and surfaces. It is very contagious and can spread quickly among children
* The diagnosis is suspected primarily clinically based on the appearance of the scalp lesion. A Wood's lamp test performed to confirm the presence of a fungal scalp infection , Dermoscopy is a useful and non invasive diagnostic tool which aids in the diagnosis of tinea capitis ,the diagnosis can be confirmed by microscopic examination of KOH,
* Fungal culture is the gold standard to diagnose dermatophytosis,
* fungal culture can help to differentiate fungal species
* The treatment of tinea capitis requires systemic antifungal therapy because topical antifungal agents cannot penetrate the hair shaft sufficiently to eradicate infection. Griseofulvin, the former gold standard agent, has been associated with treatment failure; a retrospective review of patients' medical records revealed a failure rate of 39.3% , in octobr 2007 The FDA has approved terbinafine oral granules (Lamisil), which can be sprinkled on food, for tinia capitis in children four years and older , fluconazole and Itraconazole also used in treatment of Tinea capitis although they are not FDA approved
* In the past few years , Numerous cases of tinea capitis that was initially resistant to systemic antifungal or recurred rapidly after a brief interval improvement recently have been seen
* In general, clinical resistance is considered to be the persistence or progression of an infection despite appropriate antimicrobial therapy , This resistance can be attributed to a combination of factors related to the host, the antifungal agent, or the pathogen .
