Tinea Imbricata among the Indigenous Communities: Current Global Epidemiology and Research Gaps Associated with Host Genetics and Skin Microbiota. J Fungi (Basel) 2022; 8:202. [PMID: 35205956 PMCID: PMC8880274 DOI: 10.3390/jof8020202] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2022] [Revised: 02/14/2022] [Accepted: 02/16/2022] [Indexed: 11/17/2022] Open
Abstract
Tinea imbricata is a unique fungal skin disease that mostly affects indigenous populations in Southeast Asia, Oceania, and Central and South America. The control and management of this disease among these communities are challenging given their remote locations, certain traditional practices, and severe malnutrition status. To date, there are only a handful of reports published globally, which highlights the need for a more holistic approach in addressing this skin disease. Several bodies of evidence and reports have shown that host genetic factors have a profound influence on the pathogenesis of tinea imbricata, while skin microbiota is touted to have a role in the pathogenesis of the disease. However, there are limited studies of how host genetics and skin microbiota impact disease susceptibility in the host. To improve the understanding of this disease and to find possible long-term effective treatment among the affected indigenous communities, a comprehensive literature review is needed. Hence, this review paper aims to present the current status of tinea imbricata among the indigenous communities, together with published findings on the possible underlying reasons for its specific distribution among these communities, particularly on the ways in which host skin microbiota and host genetics affect occurrence and disease patterns. This information provides valuable insights for future research by highlighting the current knowledge gaps in these areas.

Parinyarux P, Thavornwattanayong W, Soontornpas C, Rawangnam P. Towards Better CARE for Superficial Fungal Infections: A Consultation Guide for the Community Pharmacy. PHARMACY 2022; 10:29. [PMID: 35202078 PMCID: PMC8878117 DOI: 10.3390/pharmacy10010029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2021] [Revised: 02/03/2022] [Accepted: 02/09/2022] [Indexed: 12/10/2022] Open
Abstract
Superficial fungal infections (SFIs) are among the most common skin diseases worldwide and are common in many parts of Asia. Community pharmacists are well-placed to help identify and manage SFIs. However, effective management may be hindered by a suboptimal consultation process, attributed to the misalignment between consumers' and pharmacists' viewpoints. The Fungal CARE (Care, Assess, Recommend, Empower) guide, a patient-centered collaborative framework, was developed to improve pharmacist-led SFI consultations in community pharmacy. A survey on real-world consumer experiences with SFIs provided insights for aligning the Fungal CARE guide with consumer perspectives. To further optimize the guide, community pharmacists were surveyed on their current practice and challenges of managing SFIs, as well as views on the usefulness of the Fungal CARE guide. The pharmacists' survey indicated that respondents engaged with some but not all of consumers' top concerns with SFIs, such as emotional and social aspects. Pharmacists identified their greatest challenges as poor compliance with SFI treatment and limited confidence in identifying and/or managing SFIs. Encouragingly, when presented with the Fungal CARE guide, nearly all pharmacists agreed it would be helpful and would use it in practice. Implementing the Fungal CARE guide may help improve pharmacist-led consultations for SFIs and encourage better treatment outcomes.

Abstract
Dermatophytosis corresponds to a broad series of infections, mostly superficial, caused by a group of keratinophilic and keratinolytic filamentous fungi called dermatophytes. These mycoses are currently considered to be a major public health concern worldwide, particularly in developing countries such as those in the Middle East and North Africa (MENA) region. Here we compiled and discussed existing epidemiologic data on these infections in the MENA region. Most of the available studies were based on conventional diagnostic strategies and were published before the last taxonomic revision of dermatophytes. This has led to misidentifications, which might have resulted in the underestimation of the real burden of these infections in the MENA countries. Our analysis of the available literature highlights an urgent need for further studies based on reliable diagnostic tools and standard susceptibility testing methods for dermatophytosis, which represents a major challenge for these countries. This is crucial for guiding appropriate interventions and activating antifungal stewardship programs in the future.

Abstract
This study analyzed the infection of superficial mycosis and the relationship between the distribution characteristics of pathogenic fungi and age, time and sex in Northeast China in the past 10 years. We would like to provide a theoretical basis for the diagnosis and treatment of related diseases. From December 2008 to December 2018, 5,374 superficial mycoses from Northeast China were selected. The fungal species were identified by fungal microscopy, fungal culture, and species identification. Besides, the relationship between sex, age, time and the distribution of superficial mycosis and pathogenic fungi was analyzed. Among the 5,374 patients, the top three infections were tinea pedis (n=1,538, 28.62%), tinea cruris (n=1,018, 18.94%) and tinea corporis (n=938, 17.45%). The top three pathogens were Trichophyton rubrum (n=2,849, 48.65%), Trichophyton mentagrophytes (n=947, 16.14%) and Candida spp. (n=804, 13.70%). The main pathogenic fungi were dermatophytes. The age group with the highest incidence of tinea capitis was children (n=372, 6.92%). The highest incidence rate of tinea pedis was in 31-69-year adults (n=905, 16.84%); Malassezia mainly affects young people aged 15-30. Yeast and mold mostly invade the elderly patients >60 years old. The incidence of tinea cruris, tinea pedis and tinea corporis in male patients was higher than that in female patients. The incidence of onychomycosis in female patients was higher than that in male patients (P<0.05). The isolation rate of Candida, Mold, Microsporum canis, Malassezia and Sporothrix increased year by year, while that of Trichophyton rubrum, Trichophyton mentagrophyte, Trichophyton schoenleinii and Epidermophyton floccosum decreased. From December 2008 to December 2018, dermatophytes were the main pathogens of superficial mycosis in Northeast China. The distribution of disease species and pathogenic fungi varied in different gender, age and time.

Abstract
Background Tinea corporis is a common fungal infection that mimics many other annular lesions. Physicians must familiarize themselves with this condition and its treatment. Objective This article aimed to provide a narrative updated review on the evaluation, diagnosis, and treatment of tinea corporis. Methods A PubMed search was performed with Clinical Queries using the key term ‘tinea corporis.’ The search strategy included clinical trials, meta-analyses, randomized controlled trials, observational studies, and reviews. The search was restricted to the English language. The information retrieved from the mentioned search was used in the compilation of the present article. Results Tinea corporis typically presents as a well-demarcated, sharply circumscribed, oval or circular, mildly erythematous, scaly patch or plaque with a raised leading edge. Mild pruritus is common. The diagnosis is often clinical but can be difficult with prior use of medications, such as calcineurin inhibitors or corticosteroids. Dermoscopy is a useful and non-invasive diagnostic tool. If necessary, the diagnosis can be confirmed by microscopic examination of potassium hydroxide wet-mount preparations of skin scrapings from the active border of the lesion. Fungal culture is the gold standard to diagnose dermatophytosis especially if the diagnosis is in doubt and results of other tests are inconclusive or the infection is widespread, severe, or resistant to treatment. The standard treatment of tinea corporis is with topical antifungals. Systemic antifungal treatment is indicated if the lesion is multiple, extensive, deep, recurrent, chronic, or unresponsive to topical antifungal treatment, or if the patient is immunodeficient. Conclusion The diagnosis of tinea corporis is usually clinical and should pose no problem to the physician provided the lesion is typical. However, many clinical variants of tinea corporis exist, rendering the diagnosis difficult especially with prior use of medications, such as calcineurin inhibitors or corticosteroids. As such, physicians must be familiar with this condition so that an accurate diagnosis can be made and appropriate treatment initiated.
