BACKGROUND Absorption spectra of common tattoo pigments, their reaction to irradiation at 532 and 752 nm, and correlation with their titanium and iron component are important to the selection of an optimal laser device. OBJECTIVE The objectives were (1) to establish the absorption spectra of common tattoo pigments and India ink and (2) to determine their(More)
BACKGROUND Pseudofolliculitis barbae affects a large number of individuals with coarse curly hair, and present treatment options are suboptimal. OBJECTIVE We evaluated the safety and efficacy of a long-pulsed neodymium:yttrium aluminum garnet (Nd:YAG) laser in the treatment of pseudofolliculitis barbae. METHODS This was a two-phase observational study(More)
Blastomycosis is an infection that is often associated with recent military, occupational, or recreational activities near damp soil in various endemic regions, including the Great Lakes and major river valleys in the Midwest as well as various overseas regions. In the great majority of cases, the disease presents as a primary pulmonary disease with or(More)
BACKGROUND The composition of cosmetic tattoos might prove relevant to their treatment by high-powered lasers. OBJECTIVES To test the accuracy and completeness of information supplied by the tattoo ink manufacturers and to perform an elemental assay of tattoo pigments using scanning electron microscopy with energy-dispersive x-ray analysis. DESIGN(More)
Leukotoxin activity from culture supernatants of Pasteurella haemolytica serotype 1 in logarithmic growth phase caused rapid (less than 5 min) release of intracellular K+, uptake of extracellular Ca2+, and swelling of cultured bovine lymphoma cells (BL3 cells). Release of 51CrO4(2-) and lactate dehydrogenase (LDH) from BL3 cells began after 15 minutes of(More)
