In Europe, Tinea unguium has an incidence rate between 0 and 2.6% (average 0.3%) in general population. The symptoms of tinea of the nails are generally well tolerated by patients, causing a delay in medical consultation. Together these two factors represent a challenge for a pediatrician faced with diagnosis and treatment of tinea of the nails.
An increase in the number of cases of tinea of the nails was observed in the Hospital del Mar Pediatric Unit, in Barcelona. From 1976 to 1984, one patient was diagnosed with tinea of the nails (4), whereas this number has augmented considerably in the past 9 years, in which 12 patients have been diagnosed with this pathology.
Etiologic evaluation was carried out by: a) direct examination with 40% KOH at 400X; b) culture in specific medium; c) macro/micro morphologic evaluation of the colonies.
Twelve cases of T. unguium were identified, of which four patients were 12 years old or younger, seven presented onycholysis and five demonstrated enlargements and change of color of the affected nails. The average duration of disease before diagnosis was 21.6 months (range 2-60 weeks). In eight patients, tinea of the nails coincided with tinea pedis. The etiology in 10 patients was T. rubrum and in 2 patients was T. tonsurans.
Although T. unguium is a disease that presents itself at all ages, it is more frequent among the adult population, leading pediatricians to overlook T. unguium as a possible diagnosis. Possibility of T. unguium occurring in younger children should not be discarded. In our study, three patients with T. unguium were 4-8 years old.
A susceptible host is necessary for infection to proceed, and susceptibility can arise from external as well as endogenous factors.
The researchers believe that T. unguium is frequently underdiagnosed by pediatricians. A pediatrician should be aware of the following: 1) tinea of the feet could coincide as well as predispose to tinea of the nails, as was observed in 66.6% of patients in the present study, 2) environmental epidemiological factors, and 3) broken, hyperkeratinized nails with color change or uneven structure, especially on the first and/or fifth toe(s) suggest T. unguium infection. In these situations, it is paramount to conduct an etiologic study to establish proper diagnosis and treatment.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
