Synopsis
Two types of permanent waving [digital perm (DP) and croquignole winding perm (CWP)] and two waving lotions [cysteamine‐HCl, pH 9.31, liquid type (lotion A) and sodium thioglycolate, pH 9.97, cream type (lotion B)] were used for this study. The protein content was decreased by permanent waving treatments on the whole, and the degree of reduction was dependent on the hair styling and waving lotion used. The greatest decrease (by 58%) was found in hairs processed with the three‐treatment performance of DP using lotion B. SDS‐PAGE identified the presence of the two most abundant polypeptides, with approximately 48 and 60 kDa, and two large polypeptides, with approximately 200 and 210 kDa, which would belong to the keratin family. Some physical properties of the hairs (tensile strength, diameter, swelling, and elongation) were examined with the permanent waving treatments. In general, the repeated waving treatment and the use of lotion B showed more negative effects on hair care than other treatments. Some morphological changes were observed with a scanning electron microscope (SEM). The most prominent change in the hair surface was observed in the hair specimen with the three‐treatment performance of DP using lotion B. More severe signs of damage appeared on the hair with lotion B than with lotion A. As the numbers of permanent waves increased, the degree of damage to the hair surface increased on the whole. However, there was no indication of changes to the hair surface with one permanent waving treatment, as determined by SEM analysis.
Bacillary angiomatosis is the development of vascular-rich papules and nodules in response to proliferation of bacteria from the genus Bartonella. We report a case of bacillary angiomatosis in an HIV-infected male that presented as firm, vascular papules on the upper lip recalcitrant to prior treatments. Histopathologic examination showed an inflammatory infiltrate surrounding vascular proliferation and Warthin Starry Stain revealed numerous rod-shaped organisms. Serologies were positive for B. henselae IgG and resolution occurred following treatment with oral antibiotics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
