BACKGROUND The prostate specific antigen (PSA) gene has a polymorphic androgen response element (ARE) sequence with two alleles, A and G. PSA A-allele carriers have higher serum PSA levels in healthy men (HM). METHODS We analysed DNA samples from 278 (556 alleles) unrelated individuals, 127 HM and 151 prostate cancer (PC) patients, for PSA ARE1 genotypes.(More)
The study of natural and artificial phenomena generates massive amounts of data in many areas of research. This data is frequently left unused due to the lack of tools to effectively extract, analyze and understand it. Visual representation techniques can play a key role in helping to discover patterns and meaning within this data. Neuroscience is one of(More)
Methylmethacrylate was first reported in 1941 as a cause of contact dermatitis. Since then, occupational contact allergies to acrylates in dentistry, orthopedic surgery, printing industry and industry have been reported, but few reports are found in the literature as a consequence of the contact with sculptured artificial acrylic nails which are(More)
INTRODUCTION Several preservatives are currently allowed in cosmetic products in the EU. However, only a few of them are strongly represented on the market: formaldehyde, parabens, formaldehyde releasers and methylchoroisothiazolinone/methylisothiazolinone (MCI/MI). MCI/MI has been widely used during recent years for the preservation of aqueous systems in(More)
INTRODUCTION Sculptured artificial acrylic nails are widely used in developed countries. Methylmethacrylate was first reported in 1941 as a cause of allergic contact dermatitis. Since then, occupational contact allergies to acrylates in dentistry, orthopedic surgery, printing industry and other industries have been reported. OBJECTIVE We describe 3(More)
612 EJD, vol. 21, n◦ 4, July-August 2011 are sporadic, although autosomal dominant inheritance and germline mosaicisms have been described. The molecular basis of the disorder is a mutation of exon IIIa in the gene coding for fibroblast growth factor receptor-2 (FGFR-2), located on chromosome 10q26. Two FGFR2 gene missense mutations involving the(More)
A 5-month-old female infant, preterm, exclusively breast-fed, presented with a 2-month history of erythematous, erosive, and crusted patches and plaques in a peri-oral, scalp, genital, and peri-anal distribution. A clinical diagnosis of zinc deficiency was confirmed by a low serum zinc level in the infant and decreased maternal breast milk zinc. Complete(More)
Phacomatosis pigmentovascularis is a rare syndrome characterized by the coexistence of a pigmented nevus and a cutaneous vascular malformation. We report a 5-year-old boy with all the typical findings of phacomatosis pigmentovascularis type Ia. Although its existence according to the traditional classification has been questioned, this case represents a(More)
