“…Under certain conditions, both exogenous and endogenous can transform to a pathogenic form; these organisms play an important role in several diseases including PV (Bajpai et al, 2014). Results of the present study clearly demonstrate that the peak-age specific prevalence of PV was recorded among female patients; this is in agreement with Kyriakis et al (2006). Whereas prevalence of PV was higher among male patients > 40 years old.…”

“…Conversely, tinea versicolor (pityriasis versicolor), which is primarily caused by mycelial growth of Malassezia spp. , is more prevalent in adults (20s–40s) (Kyriakis et al, 2006). More detailed studies are necessary to elucidate the relationship between fungistatic property of skin and its link to pathogenic fungal colonization.…”

“…Interestingly, previous culture-based and targeted PCR-based studies demonstrated that the prevalence of major commensal Malassezia fungi on the skin of prepubertal children was lower than on adults (Faergemann and Fredriksson, 1980; Gupta and Kohli, 2004; Jang et al, 2009; Sugita et al, 2010), and the incidence of fungus-associated diseases, such as tinea capitis, tinea corporis, and tinea versicolor, varies among different age groups (Hawkins and Smidt, 2014; Kyriakis et al, 2006; Shy, 2007), suggesting differential fungistatic properties of the skin in children (prepubertal) and adults (postpubertal). In addition, we previously showed the striking differences in the nares and skin bacterial communities in adults versus children (Oh et al, 2012).…”

Understanding the skin mycobiome (fungal communities) is important because both commensal and pathogenic fungi can drive cutaneous disease depending on host status and body sites, including the scalp, feet, and groin. Interestingly, age may also affect skin fungal infections as certain dermatophytoses (i.e. tinea capitis) are more frequent in children than adults. We previously described the skin mycobiomes in healthy adults, showing lipophilic fungi Malassezia predominate in most skin sites. Since children have less sebaceous skin before puberty, we compared the fungal communities of primary clinical samples from healthy children and adults, based on sequencing of a fungal phylogenetic marker. While Malassezia predominated on trunk, head and arm skin of adults (age 20s–30s), children (age <14) had more diverse fungal communities, for example, Eurotiomycetes which includes common dermatophytes. Species-level classification showed M. globosa predominated in children. Collectively, our findings indicate that prepubertal skin is colonized by diverse fungi, whereas adult skin is predominantly obligatory lipophilic Malassezia, suggesting that fungal communities on skin profoundly shift during puberty. Mycobiome shifts during puberty are likely due to alterations in sebaceous gland activation and sebum composition. This study provides a foundational framework for studies investigating interactions between fungi, skin, and pediatric dermatophytosis.

“…2 Females were predominant in the group with pityriasis versicolor, as observed by Santana et al [28], Faergmann et al [34], Furtado et al [40] Bel em et al [41] and Miranda et al [42]. This result disagrees with those found by Chetty et al [12], Burke et al [25], Morais et al [26], Ghosh et al [27], Rao et al [30], He et al [36] Framil et al [38] and Kyriakos et al [43], in which males were prevalent.…”

“…Kyriakos et al [43] attributed the predominance of male cases to excessive sweating due to increased exposure of men to physical efforts, whereas He et al [35] suggested that there was greater activity of the sebaceous glands in men due to increased production of sex hormones. There was a predominance of females in other studies and He et al [35] attributed the fact to women's aesthetics concern.…”

Pityriasis versicolor is a frequent mycosis and the use of systemic corticotherapy is one of its predisposing factors. This is an observational, cross-sectional, analytical and comparative study, conducted from January 2012 to January 2013 in the following outpatient clinics: Dermatology Service, Cassiano Antonio Moraes Hospital (HUCAM), Vitória, ES, Brazil; Nephrology Service, HUCAM; and Leprosy Department, Maruípe Health Unit, Vitória, ES, Brazil. Patients, undergoing long-term systemic corticotherapy (or not), were assessed with respect to the presence of pityriasis versicolor. If there was mycosis, a direct mycological examination would be carried out. The spss 17.0 software was used for the statistical analysis. From the total of 100 patients, nine had pityriasis versicolor, being eight from the corticotherapy group and one from the group with no use of corticosteroids. Regarding the patients with mycosis, the prevalent age ranged from 20 to 39 years, with six patients; six were women; seven mixed race; eight were undergoing long-term systemic corticotherapy; seven were taking low-dose systemic corticosteroids; four had leucocytosis; five had normal total cholesterol and triglycerides; and four had normal glycaemia. There was increased frequency of pityriasis versicolor in the group undergoing systemic corticotherapy with statistical significance, corroborating the only study on the topic (1962).
