ABSTRACT

Tinea capitis is a common fungal infection caused by dermatophytes in children, but it is rare in infants. Although oral itraconazole has been widely used to treat tinea capitis, its use in infants is limited due to its low prevalence in this age group. A previous study reported the effectiveness of itraconazole continuous therapy in treating infantile tinea capitis caused by Microsporum canis. However, this approach has not been extended to tinea capitis caused by other fungi. In this study, we present four cases of infantile tinea capitis treated with continuous itraconazole oral solution therapy (5 mg/kg/day). Two patients were infected with M. canis, one patient with Nannizzia gypsea, and another with Trichophyton tonsurans. This study assesses the efficacy and safety of itraconazole oral solution continuous therapy, expanding our understanding by demonstrating its effectiveness for infantile tinea capitis caused by T. tonsurans and N. gypsea.

ABSTRACT

This study aimed to evaluate the current management of tinea capitis in the United States, specifically focusing on patients aged 0-2 months, 2 months to 2 years, and 2 years to 18 years. An online survey, distributed through the Pediatric Dermatology Research Alliance and the Society of Pediatric Dermatology, revealed the following preferences: fluconazole for those under 2 months, griseofulvin for those aged 2 months to 2 years, and terbinafine for those aged 2 years and older. There exists inter-provider variation in tinea capitis treatment regimens within the pediatric dermatology community.

ABSTRACT

The two fungal species Trichophyton rubrum and Trichophyton violaceum are common pathogens on human, infecting keratinized tissue of the outer body parts. Both species are belonging to the "Trichophyton rubrum complex" and share very high similarity in the genome. Secreted proteinases, key factors for keratin degradation, are nearly identical. Contrary, the ecological niches are differing. Trichophyton rubrum preferably infects skin and nails, whereas T. violaceum preferably infects the scalp. We postulate, that differences in the protease expression contribute to differences in ecological preferences. We analyzed the expression profiles of all 22 endoprotease genes, 12 subtilisins (S8A), 5 deuterolysins (M35) and 5 fungalysins (M36), for both species. To compare the influence of the keratin source, we designed experiments with human nail keratin, sheep wool keratin and keratin free cultivation media. Samples were taken at 12 h, 24 h, 48 h and 96 h post incubation in keratin medium. The expression of the proteases is higher in wool-keratin medium compared to human nail medium, with the exception of MEP4 and SUB6. Expression in the keratin-free medium is lowest. The expression profiles of the two species are remarkable different. The expression of MEP1, MEP3, SUB5, SUB11 and SUB12 are higher in T. rubrum compared to T. violaceum. MEP2, NpIIc, NpIIe, SUB1, SUB3, SUB4, SUB7 and SUB8 are higher expressed in T. violaceum compared to T. rubrum. The differences of the protease expression in the two species may expalin the differences in the ecological niches. Further analysis are necessary to verify the hypothesis.Please check and conform the edit made in title.Here I thinke the species of strains shouldnt be capital, and the right expression should be,  "Expression Profiles of Protease in Onychomycosis-Related Pathogenic Trichophyton rubrum and Tinea Capitis-Related Pathogenic Trichophyton violaceum"Author names: Please confirm if the author names are presented accurately and in the correct se-quence (given name, middle name/initial, family name).

ABSTRACT

Dermatophytoses of the skin and scalp are common disorders in the pediatric population. The resemblance of the clinical presentation to other dermatoses can make fungal infections challenging to diagnose. We present three cases of dermatophytoses in children. The presence of fungi within skin lesions was confirmed in all cases. The diagnoses were "id" reaction in response to Trichophyton tonsurans infection, Kerion celsi because of Microsporum canis infection, and hair loss during microsporosis. Based on our review and clinical experience, we suggest diagnostic paths and treatments for dermatophytoses in children.

ABSTRACT

In this study, we have formulated and analyzed the Tinea capitis infection Caputo fractional order model by implementing three time-dependent control measures. In the qualitative analysis part, we investigated the following: by using the well-known Picard-Lindelöf criteria we have proved the model solutions' existence and uniqueness, using the next generation matrix approach we calculated the model basic reproduction number, we computed the model equilibrium points and investigated their stabilities, using the three time-dependent control variables (prevention measure, non-inflammatory infection treatment measure, and inflammatory infection treatment measure) and from the formulated fractional order model we re-formulated the fractional order optimal control problem. The necessary optimality conditions for the Tinea capitis fractional order optimal control problem and the existence of optimal control strategies are derived and presented by using Pontryagin's Maximum Principle. Also, the study carried out the sensitivity and numerical analysis to investigate the most sensitive parameters and to verify the qualitative analysis results. Finally, we performed the cost-effective analysis to investigate the most cost-effective measures from the possible proposed control measures, and from the findings we can suggest that implementing prevention measures only is the most cost-effective control measure that stakeholders should consider.

ABSTRACT

We report a severe case of kerion Celsi of the scalp in a previously healthy 13-year-old girl due to Trichophyton quinckeanum, an emerging dermatophyte species in Europe. The species was definitely identified by DNA sequencing and the patient was successfully treated by oral terbinafine for 6 weeks. Kerion Celsi is a severe inflammatory form of tinea capitis, which is characterised by a purulent discharge and alopecia [1]. It typically occurs in children infected with zoophilic dermatophytes, such as Trichophyton mentagrophytes, and an increasing number of cases caused by other Trichophyton species has recently been reported [2]. Herein we report a severe case of kerion Celsi of the scalp caused by the emerging species Trichophyton quinckeanum, which was successfully treated by oral antifungal.

ABSTRACT

Kerion Celsi is an inflammatory, deep fungal infection of the scalp. It is rare in neonates but gets more common in children about 3 years and older. It represents with swelling, boggy lesions, pain, alopecia and purulent secretions. Secondary bacterial infection is not unusual after maceration. Extracutaneous manifestations include regional lymphadenopathy, fever and very rare fungemia. Id-reactions can occur. Diagnosis is based on clinical suspicion, clinical examination and medical history. Diagnosis should be confirmed by microscopy, fungal culture and molecular procedures. The most common isolated fungal species are anthropophilic Trichophyton (T.) tonsurans and zoophilic Microsporum (M.) canis, while geophilic species and moulds rarely cause Kerion Celsi. Treatment is medical with systemic and topical antifungals supplemented by systemic antibiotics when necessary, while surgery needs to be avoided. Early and sufficient treatment prevents scarring alopecia. The most important differential diagnosis is bacterial skin and soft tissue infections.

ABSTRACT

Tinea capitis is a common disease in children but rare in newborns younger than 1 month of age. Only 29 cases of tinea capitis in newborns have been described in indexed literature from 1990 until now. While antifungal agents can be used topically and systemically, systemic antifungal therapy is generally accepted as the treatment of choice for tinea capitis due to limited penetration of topical agents into the hair follicle. However, there is a lack of data on the use of systemic antifungal agents in newborns, and there are reports of successful treatment of tinea capitis in newborns using only topical therapy. In this paper, we present a case of tinea capitis in a 29-day-old female baby and review the previous 29 reported cases.

ABSTRACT

Dermatophytosis is the most common fungal infectious disease in the world, which is commonly caused by Trichophyton rubrum in China. The traditional therapies for treating dermatophytosis include topical and oral antifungal agents like terbinafine, griseofulvin, and azole antifungal drugs. However, 5-aminolevulinic acid-based photodynamic therapy (ALA-PDT) as a new alternative therapy avoids the side effects and drug resistance of traditional antifungal agents. We report two cases diagnosed as kerion and tinea faciei secondary to ulcers with CARD 9 deficiency, both of whom were infected by T.rubrum. They were both successfully treated by ALA-PDT combined with antifungal drugs, providing a feasible strategy for therapeutic choice for adult kerion and ulcer treatment.

ABSTRACT

There is increasing demand for natural and sustainable products for the treatment of dermatologic conditions. This systematic review aims to critically analyze published randomized controlled trials (RCTs) and provide evidence-based recommendations on the therapeutic use of curcumin for a variety of dermatological diseases. A systematic search of published literature was performed on July 18, 2023 using PRISMA guidelines for turmeric or curcumin for the treatment of skin diseases. Clinical recommendations were made based on the Oxford Centre for Evidence-Based Medicine guidelines. We identified 18 original randomized controlled trials for use of turmeric or curcumin for psoriasis, radiation dermatitis, oral lichen planus, pruritis, vitiligo, tinea capitis, facial erythema, and scarring. Psoriasis, cesarean section scar, and pruritus received grade of recommendation B. Radiation dermatitis, oral lichen planus, vitiligo, tinea capitis, and facial redness received grade of recommendation C or D. Curcumin was demonstrated to have an excellent safety profile in all clinical trials analyzed. Further research is required to determine optimal dosing and treatment parameters of turmeric. Additional, larger, RCTs and non-RCTs should be conducted to further investigate the safety and efficacy of curcumin as a treatment option for dermatological diseases.

ABSTRACT

Tinea capitis is a superficial fungal infection of the scalp and hair caused by Dermatophytes. It represents the most prevalent superficial fungal infection among preadolescent children worldwide, including in developing countries such as China. The highly contagious nature of tinea capitis can result in outbreaks within communal settings for children. Furthermore, pustular lesions associated with this condition can lead to permanent scarring and hair loss, imposing a significant psychological burden on affected children and their parents. This article aims to provide a comprehensive literature review encompassing the susceptible person, epidemiological characteristics, trends, etiology, modes of transmission, clinical manifestations, treatment, and prevention strategies of tinea capitis. The ultimate objective is to raise awareness, implement effective prevention and control measures, interrupt the transmission cycle, and ultimately reduce the incidence of tinea capitis in the pediatric population.
