Global perspectives for the management of onychomycosis. Int J Dermatol 2018; 58:1118-1129.

Abstract
Onychomycosis is a fungal nail infection caused by dermatophytes, nondermatophyte molds, and yeasts. This difficult-to-treat chronic infection has a tendency to relapse despite treatment. This paper aims to offer a global perspective on onychomycosis management from expert physicians from around the world. Overall, the majority of experts surveyed used systemic, topical, and combination treatments approved in their countries and monitored patients based on the product insert or government recommendations. Although the basics of treating onychomycosis were similar between countries, slight differences in onychomycosis management between countries were found. These differences were mainly due to different approaches to adjunctive therapy, rating the severity of disease and use of prophylaxis treatment. A global perspective on the treatment of onychomycosis provides a framework of success for the committed clinician with appreciation of how onychomycosis is managed worldwide.

Environmental and Genetic Factors on the Development of Onychomycosis. J Fungi (Basel) 2015; 1:211-216. [PMID: 29376909 PMCID: PMC5753111 DOI: 10.3390/jof1020211] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2015] [Revised: 08/15/2015] [Accepted: 08/19/2015] [Indexed: 11/17/2022] Open
Abstract
Since the early 20th century, onychomycosis originated with the onset of war, the use of occlusive footwear, and the mass migration of people by transportation in the United States. Even though onychomycosis has a high prevalence in the US, other parts of the world including Canada, West Africa, Southeast Asia, Northern Australia, and Europe have been well documented with cases of fungal toenail infection in their environments. Trichophyton rubrum (T. rubrum) is the major dermatophyte responsible for toenail fungal infection and is typically diagnosed in conjunction with tinea pedis, especially in individuals older than 60 years. Gender roles, age, cultural habits, shoe gear, sports activities, and genetic predisposition all contribute to the different presentation of onychomycosis in these areas where organisms like dermatophytes, candida, and molds were isolated in a variety of cases. Despite the differences in isolated pathogens, treatment outcomes remained consistent. This literature review discusses the influence of tinea pedis, genetics, shoe gear, sports, and age on the development of onychomycosis.

Kim DM, Suh MK, Ha GY. Onychomycosis in children: an experience of 59 cases. Ann Dermatol 2013; 25:327-34. [PMID: 24003276 PMCID: PMC3756198 DOI: 10.5021/ad.2013.25.3.327] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2012] [Revised: 07/27/2012] [Accepted: 08/06/2012] [Indexed: 11/29/2022] Open
Abstract
Background Although tinea unguium in children has been studied in the past, no specific etiological agents of onychomycosis in children has been reported in Korea. Objective The purpose of this study was to investigate onychomycosis in Korean children. Methods We reviewed fifty nine patients with onychomycosis in children (0~18 years of age) who presented during the ten-year period between 1999 and 2009. Etiological agents were identified by cultures on Sabouraud's dextrose agar with and without cycloheximide. An isolated colony of yeasts was considered as pathogens if the same fungal element was identified at initial direct microscopy and in specimen-yielding cultures at a follow-up visit. Results Onychomycosis in children represented 2.3% of all onychomycosis. Of the 59 pediatric patients with onychomycosis, 66.1% had toenail onychomycosis with the rest (33.9%) having fingernail onychomycosis. The male-to-female ratio was 1.95:1. Fourteen (23.7%) children had concomitant tinea pedis infection, and tinea pedis or onychomycosis was also found in eight of the parents (13.6%). Distal and lateral subungual onychomycosis was the most common (62.7%) clinical type. In toenails, Trichophyton rubrum was the most common etiological agent (51.3%), followed by Candida albicans (10.2%), C. parapsilosis (5.1%), C. tropicalis (2.6%), and C. guilliermondii (2.6%). In fingernails, C. albicans was the most common isolated pathogen (50.0%), followed by T. rubrum (10.0%), C. parapsilosis (10.0%), and C. glabrata (5.0%). Conclusion Because of the increase in pediatric onychomycosis, we suggest the need for a careful mycological examination of children who are diagnosed with onychomycosis.

Abstract
The article presents data from Russian and foreign sources related to the etiology of foot mycosis and onychomycosis. In spite of the substantial spread of data by countries and regions of the world, dermatophytes play a leading part in the etiology of foot mycosis and onychomycosis, and Trichophyton rubrum is found in most studies in more than one half of all cases. Yeast-like fungi of the Candida genus as well as mold fungi belong to less frequent pathogens of foot mycosis. However, they play a greater role in countries with hot and humid climate such as Brazil, Indonesia, Columbia and India. These data are important for the determination of organizational measures aimed at the early diagnostics of patients, timely treatment and implementation of anti-epidemic and disinfectant measures.
