Review
Onychomycosis is one of the most common nail diseases in adults but is described as infrequent in children. Data are, however, scattered and diverse. Studies have nevertheless suggested that the prevalence of onychomycosis is increasing in children lately and the aim of this review was therefore to examine this problem. Two authors individually searched PubMed, Embase, and Cochrane Library for articles on epidemiology and prevalence of onychomycosis in children. The literature search was conducted in accordance per PRISMA guidelines. In total 1042 articles were identified of which 23 were eligible for inclusion. One of the articles presented two studies and a total of 24 studies were therefore included. Seventeen studies presented data of the prevalence of onychomycosis in children in the general population and seven studies among children visiting a dermatological and pediatric department or clinic. The prevalence ranged from 0% to 7.66% with an overall discrete increase of 0.66% during the period 1972 to 2014 in population studies (not statistically significant). This review supports a trend towards an increased prevalence of onychomycosis in children, albeit based on a paucity of studies. The data suggests an increasing prevalence of onychomycosis with age, and co-infection with tinea pedis (reported in 25% of the studies). The most common pathogen reported was Trichophyton rubrum and onychomycosis was more prevalent in toenails compared to fingernails. The general characteristics of onychomycosis in children are thus similar to those described in adults.

Indian Journal of Public Health 2023The epidemiological and mycological patterns of superficial mycoses across various geographic regions of India across the last few years are changing.
BACKGROUND
The epidemiological and mycological patterns of superficial mycoses across various geographic regions of India across the last few years are changing.
OBJECTIVE
This study was performed to evaluate the epidemiological and mycological profile of superficial mycoses in India between 2015 and 2021.
METHODS
In this systematic review, the PubMed database was searched for all observational studies published between January 1, 2015, and December 31, 2021, which had evaluated the clinico-mycological profile of superficial mycoses among outpatients from various parts of India. Descriptive statistics was used to represent the results.
RESULTS
Forty studies (21 from the north, three from the northeast, five from the east, seven from the south, one from the west, and three from multiple regions of India) were included. Male patients and those of the age group of 21-40 years were most commonly affected. The proportion of dermatophytes as causative organisms was consistently high across all regions and throughout the study period (23.6%-100%). Among dermatophytes, the proportion of Trichophyton mentagrophyte (14.0%-97.2%) and Trichophyton rubrum (0%-69.1%) was consistently high across all regions. The prevalence of T. mentagrophyte showed a rising trend, while that T. rubrum showed a declining trend from 2015 to 2021.
CONCLUSIONS
The epidemiological and mycological pattern of superficial mycoses showed a fairly similar trend across various regions of India from 2015 to 2021. Dermatophytes were the main causative agents of superficial mycoses; the most common species were T. mentagrophyte and T. rubrum. A rising trend of T. Mentagrophyte infection was found.

Review
Camels are highly suited for severe desert conditions and able to provide most of the natural products like urine, which has been used as alternative medicine to treat diverse infections and disorders. There is, however, a shortage and paucity of scientific reviews highlighting the antifungal, antibacterial and antiviral effects of camel urine. By better understanding its antimicrobial characteristics, our overarching aim is to provide an exhaustive overview of this valuable natural product by synthesizing and summarizing data on the efficacy of this biofluid and also describing the potential substances exhibiting antimicrobial properties. We searched three databases in order to point out relevant articles (Web of Science, Scopus and Google Scholar) until December 2022. Research articles of interest evaluating the antimicrobial effects of camel urine were selected. Overall, camel urine furnished promising antibacterial activities against gram-positive bacteria, namely (30 mm), (22 mm), (25 mm) and (21 mm), as well as gram-negative bacteria, especially and spp., without forgetting its efficiency on as well. The excretion also showed its potency against H1N1 virus, vesicular stomatitis virus and middle east respiratory syndrome coronavirus. Similarly, the camel urine featured strong antifungal activity against and dermatophytes with a minimal inhibitory concentration of 0.625 μg/ml against , 2.5 μg/ml against and 1.25 μg/ml against and . This comprehensive review will be valuable for researchers interested in investigating the potential of camel urine in the development of novel broad-spectrum key molecules targeting a wide range of drug-resistant pathogenic microorganisms.
