Relationship between oral Kaposi ?s sarcoma and HAART : Contribution of two case reports
Two HIV infected patients not receiving Highly Active Antiretroviral Treatment (HAART) presented with epidemic Kaposi?s sarcoma of the oral cavity. One patient initially refused HAART, but when the lesion became large enough to be noticeable he agreed to HAART associated with excision of the intraoral lesion by CO2 laser. The other patient developed KS and progressed to AIDS at two years after ceasing HAART due to adverse effects; he was referred to hospital for renewed administration of HAART. In both cases, the lesions observed in the oral cavity were the first clinical manifestation of AIDS. These reports underline the close relationship between the use of HAART and the control of KS les…
High resolution image in bone biology II : Review of the literature
Bone microstructure has usually been assessed by obtaining samples invasively and analyzing them with conventional histomorphometric methods. Improvements in high-resolution image acquisition systems have enabled non-invasive assessment of bone morphology and a more precise 3-D evaluation by means of ?virtual biopsies?, permitting bone assessment in regeneration or remodeling processes. Among other applications, this imaging technique can be used for the ultrastructural analysis of bone and for studies of regeneration techniques, biomechanics in bone physiotherapy, and periimplant bone healing. This review describes the different applications of high-resolution imaging techniques in bone bi…
High resolution image in bone biology I : review of the literature
Bone microstructure has usually been assessed by obtaining samples invasively and analyzing them with conventional histomorphometric methods. Improvements in high-resolution image acquisition systems have enabled non-invasive assessment of bone morphology and a more precise 3-D evaluation by means of ?virtual biopsies?, permitting bone assessment in regeneration or remodeling processes. This review describes the characteristics and limitations of bone assessment using different high-resolution image systems (synchrotron-radiation computed tomography, micro-computed tomography, acoustic scanning microscope; micro-magnetic resonance imaging). Morphometric variables that can be obtained from t…
