Tinea of the nails underdiagnosed in children

19.11.2007
Two doctors from Hospital del Mar in Barcelona and UAB professors have observed, through a research carried out during the past 9 years, an increase in the number of children affected by tinea of the nails, as well as an underdiagnosis of this affection by paediatricians.

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.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
