Epidemiology of diseases is influenced by population socio-demographic circumstances. Therefore it can be modified along the time. There are no studies exploring epidemiological transition in dermatology. This study investigated the incidence of dermatoses in new patients from a Brazilian country town public service in 2003 and 2014. There was a significant increase in the incidence of sexually transmitted diseases, leprosy, melasma, pruritus and hidradenitis suppurativa. However, a prominent reduction in scheduling of appointments for surgeries of benign lesions, drug reactions, urticaria and superficial mycoses was detected...

Superficial mycoses are fungal infections restricted to the stratum corneum and to the hair shafts, with no penetration in the epidermis; they are: white piedra, black piedra, tinea versicolor, and tinea nigra. This study presents images of mycological tests performed in the laboratory, as well as exams performed at the authors office, in order to improve the dermatologist's knowledge about the diagnosis of these dermatoses, which are common in many countries.

BACKGROUND: Skin disorders are prevalent on primary care medical service trips in Latin America and the Caribbean and commonly include scabies, superficial mycoses, and pyoderma. There have been no previous attempts to describe protocols that international volunteer clinicians use in managing these patients. The purpose of this study was to collect North American clinical protocols used by sending organizations in their volunteer operations in Latin America and the Caribbean, summarize the most common pharmacologic and nonpharmacologic management strategies, and compare these to published international practice recommendations...

The guideline recommendations, albeit founded on thorough reviews of clinically relevant literature data, are often not immediately adaptable to everyday life. Considering the marked heterogeneity of superficial mycoses, each of them requires specific management in a real life context; in all cases diagnostic confirmation is required with microscopic and culture examination. In tinea capitis oral therapy is necessary (minimum six weeks) and should be continued until clinical and, above all, mycological healing...

The genus Fusarium is widely recognized for its phytopathogenic capacity. However, it has been reported as an opportunistic pathogen in immunocompetent and immunocompromised patients. Thus, it can be considered a microorganism of interest in pathogenicity studies on different hosts. Therefore, this work evaluated the pathogenicity of Fusarium spp. isolates from different origins in plants and animals (murine hosts). Twelve isolates of Fusarium spp. from plants, animal superficial mycoses, and human superficial and systemic mycoses were inoculated in tomato, passion fruit and carnation plants, and in immunocompetent and immunosuppressed BALB/c mice...

Among the fungi, dermatophytes are the major cause of spectrum of superficial mycoses medically known as dermatophytosis (tinea) in human and animal. Treatment of these infections has still remained difficult. The aim of this survey was to evaluate in vitro anti-dermatophytic activity of ethanolic extract (EtOH) from Satureja khuzestanica leaf (SKLE) against some clinically important dermatophyte species from the genera of Trichophyton, Microsporum and Epidermophyton. Minimal inhibition concentration (MIC) of SKLE was tested against 14 dermatophyte strains of 5 species by using agar dilution method...

The resistance of microorganisms to antimicrobial drugs is a major issue for public health, with important consequences in terms of morbidity, mortality and resource use. The phenomenon is so serious that in some areas of the world resistant strains to all available drugs have been selected. Many conditions may result in the development of resistance: they include the indiscriminate or inappropriate (e.g., for viral infection or colonization) use of antibiotics, the excessive duration of the prescribed treatment regimens, as well as inadequate dosing or administration routes...

INTRODUCTION: Dermatophytes are a group of fungi which infect keratinized tissues and causes superficial mycoses in humans and animals. The group comprises of three major genera, Trichophyton, Microsporum and Epidermophyton. Among them Trichophyton rubrum is a predominant anthropophilic fungi which causes chronic infections. Although, the infection is superficial and treatable, reinfection/coinfection causes inflation in the treatment cost. Identifying the source and mode of transmission is essential to prevent its transmission...

Members of Candida species cause significant health problems, inducing various types of superficial and deep-seated mycoses in humans. In order to prevent from Candida sp. development, essential oils are more and more frequently applied, due to their antifungal activity, low toxicity if used appropriately, and biodegrability. The aim of the study was to characterize the early alterations in Candida albicans metabolic properties in relation to proteins and chromosomal DNA profiles, after treatment with peppermint and clove oils at sub-inhibitory concentrations...

In Algeria, superficial mycoses are very commonly diagnosed. Deep fungal infections are less often observed. Few data from Algeria are found in the literature. We report for the first time the main causes of these diseases in our country and provide burden estimates. We searched for existing data and estimated the incidence and prevalence of fungal diseases based on the population at risk and available epidemiological data. Demographic data were derived from the Service (Office) of the Statistics (ONES), World Health Organization (WHO), The Joint Nations Programme on HIV/AIDS (UNAIDS) and national published reports...

Dermatophyte species, isolation and identification in clinical samples are still difficult and take a long time. The identification and molecular epidemiology of dermatophytes commonly isolated in a clinical laboratory in Turkey by repetitive sequence-based PCR (rep-PCR) were assessed by comparing the results with those of reference identification. A total of 44 dermatophytes isolated from various clinical specimens of 20 patients with superficial mycoses in Kayseri and 24 patients in Hatay were studied. The identification of dermatophyte isolates was based on the reference identification and rep-PCR using the DiversiLab System (BioMerieux)...

Dermatophytes are the most common agents of superficial mycoses in humans and animals. The aim of the present investigation was to systematically identify the extracellular, possibly secreted, proteins that are putative virulence factors and antigenic molecules of dermatophytes. A complete gene expression profile of Arthroderma benhamiae was obtained during infection of its natural host (guinea pig) using RNA sequencing (RNA-seq) technology. This profile was completed with those of the fungus cultivated in vitro in two media containing either keratin or soy meal protein as the sole source of nitrogen and in Sabouraud medium...

The organisms colonizing a living host create together with their host a holobiome. The holobioms are networks of mutualistic interactions between host`s cells and microorganisms communities. The fungi are among these microorganisms and have been also well known to infect human and animals. These organisms are associated with a wide range of diseases as superficial or systemic mycoses. Fungi as colonizers can also modify host physiology and metabolism, energy acquisition, vitamin-cofactor availability, development and function of immune system, and even host behavior...
