BACKGROUND Photodynamic therapy (PDT) using topical delta-aminolevulinic acid (delta-ALA) is an effective treatment for Bowen disease and certain basal cell carcinomas (BCCs), but its place in clinical practice remains to be established. Patients with large and/or multiple lesions of Bowen disease or BCC can represent a considerable therapeutic challenge. We suggest that delta-ALA PDT may be of...

A class of vacuum initial-data sets is described which are based on certain expressions for the extrinsic curvature first studied and employed by Bowen and York. These expressions play a role for the momentum constraint of General Relativity which is analogous to the role played by the Coulomb solution for the Gauss-law constraint of electromagnetism.

Il s'agit d'un patient de 59 ans, qui présentait de multiples lésions génitales évoluant depuis 2 ans. L'examen a objectivé 2 tumeurs verruqueuses superficielles, à bordure pigmentée et à surface végétante, siégeant respectivement au niveau sus-pubien et sur le pli inguinal droit; une macule pigmentée hétérogène au niveau hypogastrique, et de multiples plaques noirâtres homogènes à surface verr...

The anonymous text Ventorum situs et nomina, once held to be by Aristotle himself, gives the local names of 10 topic winds as well their directions. It is not an elaboration wind-rose that Aristotle, for example, describes in Meteor. 2.5, though many scholars have assumed this, but a presentation weather-map inhabited world (οἰκουμένη). What seems important author collecting under so much direc...

Linear porokeratosis is a genodermatosis, caused by a clonal proliferation of keratinocytes along the lines of Blaschko. This type of porokeratosis is particularly susceptible to malignant degeneration e.g. to Bowen disease, a squamous cell carcinoma (SCC) in situ with the potential for significant lateral spread. Here we report a case of linear porokeratosis on the left leg of a 56-year-old ma...
