RESUMO
Cutaneous amyloidosis can be a part of a systemic disease or can result from a localized process limited to the skin. It usually presents as pruritic hyperpigmented macules, papules or nodules, which are notoriously resistant to treatment. We performed a hospital-based pilot case series to assess the efficacy and safety of sequential salicylic acid (SA) and glycolic acid (GA) chemical peels. Patients underwent sequential chemical peel therapy with SA 20% and GA 35% used alternately each week for a total of 6 weeks. At subsequent follow-up visits, good clinical outcome and long-term maintenance was observed. This study highlights the promising role of chemical peels in this difficult and distressing disorder.

Self-generated magnetic fields produced in laser plasmas at moderate laser intensities have been measured using a three-channel polaro-interferometer. The main elements of this device are two birefringent calcite wedges placed between two crossed polarizers. Using this device, the spatial profiles of (a) the rotation angle (polarometry), (b) the electron density (interferometry), and (c) the transmitted probe beam intensity (shadowgraphy) are recorded simultaneously using a digital camera with a large format CCD in a single laser shot. Magnetic fields of 2-4 MG had been estimated in aluminum plasma at laser intensities ~10(13) W/cm(2). It is also possible to use this device in other configurations to get time resolved information.
