Lithic artefacts are usually associated with the different knapping methods used in their production. Flakes exhibit metric and technological features representative of flaking method to detach them. However, lithic production is a dynamic process which discrete can be blurred, vary throughout process. An intermediate between discoid Levallois commonly referred under an umbrella terms (the pres...

The use of cultured human epithelial cells as a substrate for the detection of antinuclear antibodies (ANAs) improves the sensitivity of detection above the standard substrates used. Standard antisera have been screened against a series of epithelial cell lines, including keratinocytes. Selected cells have then been used to detect ANAs in 78 patients with discoid lupus erythematosus.

The authors report the case of a 10-year-old girl with Graves' disease (GD), treated with propylthiouracil, who developed uveitis and polyarticular arthritis, and whose mother also had GD and discoid lupus. The differential diagnosis of inflammatory arthritis that appears in a child with autoimmune thyroid disease managed with antithyroid drugs is discussed.

Introduction Chronic granulomatous disease (CGD) is a primary immune deficiency that characterized with recurrent infections and granuloma formation. A variety of autoimmune disorders and immune-mediated phenomena such as inflammatory bowel disease, discoid lupus erythematous, juvenile idiopathic arthritis, Ig A nephropathy, sarcoidosis, rheumatoid arthritis, idiopathic thrombocytopenia, eosino...

We report phakomatosis pigmentovascularis (PPV) detected in a 40yearold male characterized by the presence of a port-wine stain in the background of aberrant Mongolian spots covering the back, nevus of Ota, ocular melanosis, epidermal nevus and a scaly patch with the diagnosis of discoid lupus erytematosus. These associations have not been reported yet.
