Changing Epidemiology of Tinea Capitis in Athens, Greece: The Impact of Immigration and Review of Literature. J Fungi (Basel) 2023; 9:703. [PMID: 37504692 PMCID: PMC10381159 DOI: 10.3390/jof9070703] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Revised: 06/23/2023] [Accepted: 06/24/2023] [Indexed: 07/29/2023] Open
Abstract
Mass population movements have altered the epidemiology of tinea capitis (TC) in countries receiving refugees. Periodic monitoring of the local pathogen profiles may serve as a basis for both the selection of appropriate empirical antifungal therapy and the implementation of preventive actions. Therefore, we investigated the impact of an unprecedented immigration wave occurring in Greece since 2015 on the epidemiological trends of TC. All microbiologically confirmed TC cases diagnosed during the period 2012-2019 in a referral academic hospital for dermatological disorders in Athens, Greece, were retrospectively reviewed. A total of 583 patients were recorded, where 348 (60%) were male, 547 (94%) were children and 160 (27%) were immigrants from Balkan, Middle Eastern, Asian as well as African countries. The overall annual incidence of TC was 0.49, with a significant increase over the years (p = 0.007). M. canis was the predominant causative agent (74%), followed by T. violaceum (12%), T. tonsurans (7%) and other rare dermatophyte species (7%). M. canis prevalence decreased from 2014 to 2019 (84% to 67%, p = 0.021) in parallel with a three-fold increase in T. violaceum plus T. tonsurans rates (10% to 32%, p = 0.002). An increasing incidence of TC with a shift towards anthropophilic Trichophyton spp. in Greece could be linked to the immigration flows from different socioeconomic backgrounds.

Correlation of clinical characteristics, by calculation of SCIO index, with the laboratory diagnosis of onychomycosis. Braz J Microbiol 2022; 53:221-229. [PMID: 35000126 PMCID: PMC8882508 DOI: 10.1007/s42770-021-00676-z] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2021] [Accepted: 12/24/2021] [Indexed: 01/19/2023] Open
Abstract
INTRODUCTION Onychomycosis is a chronic fungal infection with increasing incidence and the global prevalence is estimated to be 5.5%. The aim of our study was to perceive objectively severity of onychomycosis by calculating Scoring Clinical Index for Onychomycosis and to correlate this index with accurate laboratory diagnosis in our patients. MATERIALS AND METHODS The study population comprised of 417 patients with laboratory confirmed onychomycosis. For each patient, we recorded basic demographic information, site of infection, the most affected nail with onychomycosis, clinical presentation, and type of onychomycosis. The evaluation of the disease severity was based on Scoring Clinical Index for Onychomycosis which was calculated for every patient separately. Mycological identification was done by microscopy and fungal culture. RESULTS The majority of patients had distal and lateral subungual onychomycosis (95.44%) that was localized on big toe (62.59%), with female to male ratio 1.24:1. Male patients had significantly more nails affected with onychomycosis compared with female patients (p = 0.011), while female had significantly more often onychomycosis on fingernails 2-5 (p < 0.05), and they reported significantly more often pain (p < 0.05) and esthetic problems (p < 0.05). Mean Scoring Clinical Index for Onychomycosis was 16.76. Dermatophytes were most frequently isolated (91.85%). In patients with onychomycosis caused by dermatophytes, Scoring Clinical Index for Onychomycosis had significantly higher values (p = 0.032). CONCLUSION Comprehensive understanding of disease characteristics will allow introduction of individualized treatment plan for each patient, based on proper fungal identification and standardized method of evaluating disease severity, which could help the patient achieve a complete cure.

Abstract
OBJECTIVE Tinea manuum is considered in Italy as an uncommon infection, although no recent epidemiological data are available. METHODS In the period 2000-2018, we observed in the metropolitan area of Milan 18 patients with mycologically tinea manuum. RESULTS The infection was monolateral in all patients and characterised by erythema and scaling; in two patients, each vesicles and pustules were present. Two patients had also onychomycosis of one fingernail. No cases of simultaneous tinea pedis were observed. As far as the job of these patients is concerned, seven of them were masseurs, three barbers, two cattlemen, two masons, one car mechanic, one florist, one maid and one veterinarian. Trichophyton rubrum was isolated in 6 patients, Microsporum canis in 4, Trichophyton gypseum in 3, Trichophyton verrucosum in 3 and Trichophyton violaceum in 2 patients. CONCLUSION Masseurs were the most affected. Trichophyton rubrum and Microsporum canis were the most frequent isolated dermatophytes.

Abstract
Dermatophytoses are among the most frequently diagnosed skin infections worldwide. However, the distribution of pathogenic species and the predominating anatomical sites of infection vary with geographical location and change over time. The aim of this study was to determine the epidemiological and aetiological factors of dermatophytoses in Crete, Greece over the last 5-year period (2011-2015) and their incidence in relation to the gender and the age of the patients. We compared our findings with those previously reported from the same area and from other parts of the world. A total of 2,910 clinical specimens (skin scrapings, nail clippings, and hair specimens) obtained from 2,751 patients with signs of dermatomycoses were examined using direct microscopy and culture. Overall, 294 specimens (10.1%) were proved mycologically positive for dermatophytes. The age of the patients ranged from 2 to 86 years (mean age, 37 years). Tinea corporis was the predominant clinical type of infection, followed by tinea unguium, tinea pedis, tinea capitis, tinea faciei, tinea cruris and tinea manuum. Among dermatophytes, eight species were isolated: Microsporum canis (35.8%), Trichophyton rubrum (35.1%), Trichophyton mentagrophytes (23.3%), Epidermophyton floccosum (2.5%), Microsporum gypseum (1.8%), Trichophyton violaceum (0.7%), Trichophyton verrucosum (0.4%), and Trichophyton tonsurans (0.4%). In our area, the most common dermatophyte was M. canis followed by T. rubrum. Increased migration, mass tourism, and climate changes will contribute to further changes in the epidemiology of dermatophytoses in our area. Continuing studies are necessary for determining the new epidemiological trends and to implement the appropriate control measures.

Abstract
Background and Purpose: The epidemiological features of dermatophytoses have been characterized in many geographical locations of Iran, but not in Guilan, North of Iran. This study was carried out to determine the distribution pattern of dermatophytoses and their relevant agents in Guilan, North of Iran, over a period of one year, from April 2010 to April 2011. Materials and Methods: The clinical samples of skin, hair, and nail from 889 outpatients (317 men vs. 572 women) were used for direct microscopy and culture. All the culture-positive samples were then subjected to amplification of the internal transcribed spacer (ITS) of the nuclear rDNA followed by a restriction fragment length polymorphism (RFLP) assay to verify the causative agents. Results: The infection was confirmed in 90 (44.3%) males and 113 (55.7%) females. The most common type of dermatophytoses was tinea cruris (42.9%), followed by tinea pedis (20.2%), tinea corporis (11.3%), tinea unguium (7.4%), tinea faciei (6.9%), tinea manuum (6.4%), and tinea capitis (4.9%). ITS-RFLP based of the identification of isolates, showed that the infections were significantly associated with anthropophilic species, of Trichophyton rubrum (41.9%), Epidermophyton floccosum (19.7%), T. tonsurans (5.4%), and T.violaceum (2%). Other causative agents were T. interdigitale (22.6%), Microsporum canis (4.9%), T. verrucosum (2.5%), and M. gypseum (1%). Conclusion: The higher prevalence of T. rubrum, as the agent of dermatophytoses, than other species has never been reported from Iran and is of public health concern because of the chronic nature of infections with anthropophilic species. To thoroughly investigate the epidemiological trend of dermatophytoses in Iran, further periodical and molecular-based studies are necessary.

Abstract
Accurate identification of dermatophyte species is important both for epidemiological studies and for implementing antifungal treatment strategies. Although nucleic acid amplification-based assays have several advantages over conventional mycological methods, a major disadvantage is their high cost. The aim of this study was to develop a rapid and accurate real-time PCR-based high-resolution melting (HRM) assay for differentiation of the most common dermatophyte species. The oligonucleotide primers were designed to amplify highly conserved regions of the dermatophyte ribosomal DNA. Analysis of a panel containing potentially interfering fungi demonstrated no cross reactivity with the assay. To evaluate the performance characteristics of the method, a total of 250 clinical isolates were tested in comparison with the long-established PCR-RFLP method and the results were reassessed using DNA sequencing, as the reference standard method. The assay is able to type dermatophytes using normalised melting peak, difference plot analysis or electrophoresis on agarose gel methods. The results showed that, in comparison to PCR-RFLP, the developed HRM assay was able to differentiate at least 10 common dermatophytes species with a higher speed, throughput and accuracy. These results indicate that the HRM assay will be a useful sensitive, high throughput and cost-effective method for differentiating the most common dermatophyte species.

Abstract
Dermatophytosis is among the most common superficial mycoses in Iran. The purpose of this report was to update the clinical and mycological features of human dermatophytosis in the Khuzestan, southwestern Iran. In the framework of a one-year survey, a total of 4120 skin, hair and nail samples obtained from the outpatients with symptoms suggestive of tinea were analyzed by using direct microscopy, culture and molecular identification methods. Strains isolated from cultures were subjected to amplification of the nuclear rDNA ITS regions in a PCR assay followed by an early established RFLP analysis. For confirmation of species identification, 100 isolates as representatives of all presumable species were subjected to ITS sequencing. Infection was confirmed in 1123 individuals (27.25 %) in the age range of 1-89 years by direct microscopy and/or culture including 603 males versus 520 females. Frequencies of infections were the highest and the lowest in age groups of 21-30 and 11-20 years, respectively. Tinea corporis was the most prevalent clinical manifestation followed by tinea cruris, tinea capitis, tinea manuum, tinea pedis, tinea unguium, tinea faciei and tinea barbae. Trichophyton interdigitale (58.7 %) was the most dominant isolate followed by Epidermophyton floccosum (35.4 %), Microsporum canis (3 %), T. rubrum (1.5 %), T. species of Arthroderma benhamiae (0.5 %), T. tonsurans (0.3 %) and T. violaceum (0.3 %). Other species included M. gypseum, M. fulvum and T. verrucosum (each one 0.1 %). Such a high occurrence of infection with T. interdigitale, which has not been reported from Iran, is due to the use of accurate molecular methods based on new species concept in dermatophytes. The prevalence of dermatophytoses caused by zoophilic species remarkably increased and Trichophyton species of A. benhamiae has emerged as a new agent of dermatophytosis in southwestern Iran, while infections due to anthropophilic species, except E. floccosum, took a decreasing trend.

Abstract
Background. Dermatophytosis is common worldwide and continues to increase. Objective. This study was undertaken to determine the prevalence of dermatophytosis and the spectrum of ringworm fungi in patients attending a tertiary hospital. Methods. Samples were collected from 305 patients. A portion of each sample was examined microscopically and the remaining portion of each sample was cultured onto plates of Sabouraud's dextrose agar containing chloramphenicol with and without cycloheximide. Dermatophyte isolates were identified by studying macroscopic and microscopic characteristics of their colonies. Result. Of 305 samples, fungi were detected in 166 (54.4%) by KOH of which 95 were dermatophytes while 242 (79.4%) samples were culture positive of which 130 isolates were dermatophytes. Among dermatophyte isolates T. violaceum was the most common (37.7%) cause of infection. Tinea unguium was the predominant clinical manifestation accounting for 51.1% of the cases. Patients with age group 25–44 and 45–64 years were more affected. T. violaceum was the most common pathogen in tinea unguium and tinea capitis, whereas T. mentagrophytes was the most common pathogen in tinea pedis. Conclusion. Further intensive epidemiological studies of ring worm fungus induced dermatophytosis which have public health significance are needed.

Abstract
Microsporum gypseum is a geographically widespread geophilic fungus that infects animals and humans. M. gypseum infection on the scrotum is very rare and can be easily misdiagnosed because of a lack of inflammatory reaction. Here we describe a patient with pseudomembranous-like tinea of the scrotum resulting from M. gypseum.

Abstract
Dermatophyte infections are very common worldwide and their epidemiological characteristics vary according to the geographical region and have altered in the last decades. The aim of the present investigation was to determine the diversity of causative agents of dermatophytoses and describe the epidemiological condition of infection in Isfahan, Iran, between 2003 and 2012. Specimens were collected from hair, nail, and skin and were examined by conventional methods such as direct microscopy, culture on sabouraud dextrose agar with chloramphenicol and cycloheximide (Mycosel agar) and sabouraud glucose agar, Trichophyton agars, growth on rice grains, urease test, and hair perforation test. Of 13,469 clinically suspected cases, 11.5% were affected with dermatophytoses. Tinea capitis was the most frequent form of infection (52.7%), followed by tinea corporis (24%), tinea pedis (8.9%). Trichophyton verrucosum was the most prevalent causative agent (40.6%), followed by T. mentagrophytes var. interdigitale (17.6%), Epidermophyton floccosum (13%), T. violaceum (12%), T. rubrum (4.1%). Age range of patients was between 1 and 80 years. Housewives were the most patients in our study. The study emphasizes importance of epidemiological surveys of dermatophyte species for the better management of infection.

Abstract
A 41-year-old woman presented with a pruritic rash on the face that was of 3 months duration. During that time, it had been successively misdiagnosed as psoriasis vulgaris, systemic lupus erythematosus, facial dermatitis at other hospitals, and had been treated with agents that included acitretin and prednisone. Finally, fungi were found in the lesions by optical microscopy, and the fungal culture was positive for Microsporum gypseum, and was diagnosed as a Microsporum gypseum infection. The lesions eventually cleared completely after 8 weeks of antifungal treatment.

Abstract
Tinea faciei (TF) is a common clinical form of tinea in children that is frequently misdiagnosed and treated with corticosteroids. No large case series of TF focusing on children have been published. The aim of this study was to analyze the main epidemiologic, clinical, and microbiologic features of TF in children over a period of 30 years and compare these features with those of other tineas. We undertook a retrospective study of 818 cases of tinea in children at a referral hospital in southern Spain, diagnosed between 1977 and 2006, concentrating for this study on TF. Of the 73 cases of TF diagnosed, 50.7% were in girls. Most children (46.6%) were 4 to 9 years old. At the time of diagnosis, 29.2% of the cases had been treated with topical steroids. The most frequently isolated dermatophyte was Trichophyton mentagrophytes, which was isolated significantly more frequently in TF than in the other tineas. Cases of TF in children were not extremely unusual, emphasizing that TF must be considered in children with inflammatory facial eruptions. This consideration and the more-frequent use of mycologic tests can help achieve the correct diagnosis, when present.

Abstract
The aim of this study was to determine the frequency of tinea pedis and manuum (dermatophyte infections of the hands and feet) in adults in rural areas of Turkey, the risk factors and self-administered treatment options. A total of 2,574 people living in a rural area were enrolled in the study. Participants were asked demographic data, hygienic habits in a questionnaire. KOH preparations and culture were performed from suspicious lesions. Medical and alternative therapy methods and former dermatophytosis diagnosis history were taken from the respondents with suspicious lesions. Microbiological samples were taken from 285 (11.1%) participants. Culture was positive in 109 (4.2%) of those. The most common agent was Trichophyton rubrum. The predisposing factors were found as age older than 40, male gender and obesity. Forty-nine (44.9%) of patients had taken a medical therapy, 56 (51.4%) had performed non-medical methods (cologne, Lawsonia inermis-Henna and softener creams). Patient's education about the treatment compliance is important.

Abstract
Considerable changes in the dermatophyte spectrum have been observed in the past century. Hence, many authors point out the necessity of performing periodical overviews of the mycological flora producing mycoses in humans in a given area. Analysis of dermatophyte species was performed, which were isolated from the lesions in patients suspected of superficial mycosis and referred to the Department of Mycology. The materials were isolated from patients suspected of superficial mycosis from Kraków region from January 1, 1972 through December 31, 2007. A total of 4983 dermatophyte strains were isolated from 23 124 specimens, which amounts to 21.5%. The percentage of dermatophytes isolated in the past decade decreased to 13.1% in the year 2007. Trichophyton rubrum outnumbered Trichophyton mentagrophytes during the entire survey period: 62.4 vs. 33.5%. The participation of Microsporum canis amounted to 1.71% and that of Epidermophyton floccosum to 1.32%. The species M. canis appeared by the end of the 1980s. The remaining dermatophyte species comprised 1% of the isolates. A considerable decrease in dermatophyte isolations has been observed since 2000. Trichophyton rubrum outnumbered T. mentagrophytes during the entire period of study. The percentages of T. rubrum and T. mentagrophytes are decreasing while the percentages of other dermatophytes are slowly increasing.

Abstract
Secondary metabolites 5-acetyl-3beta-angeloyloxy-2beta-(1-hydroxyisopropyl)-2,3-dihydrobenzofurane (1), 5-acetyl-3beta-angeloyloxy-2beta-(1-hydroxyisopropyl)-6-methoxy-2,3-dihydrobenzofurane (2), espeletone (3), encecalinol (4), O-methylencecalinol (5), encecalin (6), sonorol (7), taraxerol (8), (+)-beta-eudesmol (9), and a mixture of beta-sitosterol and stigmasterol, were isolated from the aerial parts of Ageratina pichinchensis var. bustamenta. The antimicrobial activity of compounds 6, 8 and 9, together with derivatives 9a and 9b against the most important dermatophytes responsible for tinea pedis infection, Trichophyton rubrum and T. mentagrophytes, and against Candida albicans and Aspergillus niger were determined, showing that the three natural products were active against both Trichophyton species. Ageratina pichinchensis var. bustamenta is used in folk medicine to treat skin infections and wounds, and this study confirms that the n-hexane extract contains metabolites which are responsible for these utilities.

Abstract
The distribution of dermatophytes varies in different countries and geographical areas depending on several factors. To determine the frequency of aetiological agents and the clinical variants of dermatophytoses, we carried out a study between 1998 and 2007. Out of 25 432 subjects suspected to have superficial mycoses, 9960 (39.2%) were affected with dermatophytoses; 14957 positive samples were obtained. The mean age was 35.7 years (range: 21 days to 97 years). Sex ratio was 0.9. Our patients were from urban regions in 81.9% of cases. The most common type of infection was onychomycosis (30.3%), followed by tinea pedis (24.8%), intertrigo (21.7%), tinea corporis (11.4%) and tinea capitis (9.6%). Fifteen patients had generalised dermatophytosis. Hadida and Schousboe disease was diagnosed in one case with lethal evolution. The most isolated dermatophyte was Trichophyton rubrum (74.5%), followed by T. violaceum (7.9%), T. mentagrophytes (7.5%), Microsporum canis (3.8%), Epidermophyton floccosum (0.7%) and T. verrucosum (0.54%). Other species were occasionally isolated: T. schoenleinii, T. tonsurans, M. audouinii and M. ferrugineum. The prevalence of dermatophytoses remains high in our country (996 cases/year). Trichophyton rubrum is the predominant causal agent. However, zoophilic agents become more prevalent. Epidemiological surveys are an essential tool for developing strategies for infection control.

Abstract
In this study, we examined dermatophyte infections in patients referred to the Department of Dermatology, EL-Houd El-Marsoud Hospital, Cairo, during March 2004 to June 2005. Of 506 patients enrolled in this investigation, 403 (79.6%) were clinically diagnosed as having dermatophytoses (age range 6-70 years; males 240; females 163). Species identification determined by observation of their macroscopic and microscopic characteristics was complemented with sequencing of the internal transcribed spacer ITS1-5.8S-ITS2 rDNA region. The most common dermatophyte infection diagnosed was tinea capitis (76.4%), followed by tinea corporis (22.3%) and tinea unguium (1.2%). The most frequently isolated dermatophyte species was Trichophyton violaceum, which accounted for most (71.1%) of all the recovered dermatophytes, followed by Microsporum canis (21.09%), Trichophyton rubrum (6.2%), and Microsporum boullardii (0.49%); both Epidermophyton floccosum and Trichophyton tonsurans were each only rarely isolated (0.24%).
