[Effects of solar radiation and an update on photoprotection].

Sunburn, immunodepression, photoaging, and photocarcinogenesis, are some of the most significant adverse effects of solar radiation in humans. Children are population group of special vulnerability, due to the fact that exposure to the sun has more pronounced biological effects compared to adults. Furthermore, childhood is a critical period for promoting the development of photo damage and photocarcinogenesis in the later stages of life if adequate measures at not put into place.

[Phase III study of the efficacy and safety of ciclopirox olamine cream in small children with dermatomycosis].

Background: There is scarce information on the use of ciclopirox olamine in children.

Aims: The aim of this study was to evaluate the efficacy and safety of ciclopirox olamine cream 1% for the treatment of dermatomycosis in pediatric patients.

Methods: A multicenter, non-randomized, open-label, phase iii study was conducted on patients aged 3 months to 9 years diagnosed with dermatomycosis confirmed by direct microscopy and culture, and treated with ciclopirox olamine cream 1% for 28 days.

"Buen Rayito Study": awareness, attitudes and behavior of teenagers to sunlight through a web based system in Spain.

Background: The exponential rise in cutaneous cancers underscores the need to promote primary prevention, emphasising exposure to ultraviolet radiation as the main modifiable risk factor. Children and adolescents are especially vulnerable to radiation.

Objectives: Our objectives were to determine the knowledge and behavior of a Spanish adolescent population in relation to sun exposure thorough a web-based system.

Subcutaneous phaeohyphomycosis due to Alternaria infectoria in a renal transplant patient: surgical treatment with no long-term relapse.

Background: Phaeohyphomycosis can be caused by a number of different species, being the most common Alternaria alternata and Alternaria infectoria. The biggest risk factor for the development of the infection is immunosuppression.

Aims: We present the case of a 64-year-old male renal transplant patient who came to hospital for presenting a tumour in the Achilles region which had been gradually growing in size.

Extensive tinea in a patient with severe combined immunodeficiency.

Severe combined immunodeficiency (SCID) is a heterogeneous group of disorders characterized by a defect of T and B cell immunity with a genetic origin in most cases. Although the X-linked recessive form is most common (60-70%), there are autosomal recessive forms (20%) and spontaneous mutations. While SCID may present with many nosocomial infections, dermatophyte infections are not common.

[Angiosarcoma in chronic lymphedema].

Angiosarcoma that develops on a limb with chronic lymphedema is called Stewart-Treves syndrome. This typically appears as a complication of a long course lymphedema located on the arm, after mastectomy and/or radiotherapy due to breast cancer. There are cases of Stewart-Treves syndrome in chronic lymphedema in the upper limb contralateral to the breast treated for cancer and in chronic lymphedema of the leg.
