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.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
