We describe the MR features in a case of multiple intraspinal abscesses involving almost the whole of the spinal cord in a 3-year-old child. The presence of a dermal sinus helped us in the preoperative diagnosis.

Numerous publications and reports have expressed health and safety concerns about the production and use of nanoparticles, especially in areas of exposure monitoring, personal use, and environmental fate and transport. We suggest that stable isotopic tracers, which have been used widely in the earth sciences and in metabolic and other health-related studies for several decades, could be used to...

1. Source of contaminant release into the environment. 2. Environmental media (including groundwater, surface water, air, soil, sediment, household dust, biota) serve to move contaminants from the source to points where human exposure can occur. 3. Point of exposure (a location where humans contact a contaminated medium, such as a playground, water body, well water, and food services). 4. Route...

background: this study was focused on the probability of carcinogen risk of low-level ingestion and dermal exposure with polycyclic aromatic hydrocarbons (pahs) from drinking water in tehran, capital of iran. methods: concentrations of 16 pahs were measured in the tap, bottled and heated tap water in four different seasons. using a questionnaire-based survey, exposure with pahs from drinking wa...

objective(s):skin extracellular matrix, which contains type i and type iii collagens, is involved in skin development. the aim of this study was to investigate type iii collagen distribution pattern as well as its changes during pre and post-natal skin morphogenesis in rats. materials and methods: ventral skins of wistar rat embryos at different stages from 10 to 20 gestational day (e10-e20) an...

Childhood dermal tumors with melanocytic features is an unusual tumor that can create diagnostic confusion. Among them, paraganglioma-like melanocytic tumors- previous included in melanocytic tumors of uncertain malignant potential- has some particular histopathologic and immunohistochemical features. We describe a case of 13 years old girl with a paraganglioma-like dermal melanocytic tumor of ...

An earlier model of colour formation within normal human skin was extended to include architectural distortions associated with various pigmented skin lesions, including malignant melanoma. The extended ve-layer model makes it possible to derive parameters characterising the thickness and pigment composition of the skin layers from calibrated colour and infrared images of skin lesions. The extr...

normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 background : recently autologous fat tissue transfer has gained much popularity. on the other hand, applying the transferring methods with a higher survival rate is still controversial. the aim of this study is to compare dermis-fat graft and dermal-fascia-fat graft. methods : this animal study was conducted in 2008-2009. ...

This paper reports on an experimental study of dermal exposure to neat methanol in human volunteers for the purposes of estimating percutaneous absorption rates, permeation kinetics, baseline (pre-exposure) levels of methanol in blood, and inter- and intrasubject variability. A total of 12 volunteers (seven men and five women) were exposed to methanol via one hand for durations of 0 to 16 min i...
