A pathologic condition is described, characterized by rampant necrosis of gingival mucosa, periodontium, and related osseous structures associated with systemic infection with the human immunodeficiency virus (HIV). It is believed that this condition is an extension beyond the normal clinical course of HIV-periodontitis (HIV-P) and manifests itself in three progressive stages: (1) HIV-associated gingivitis, (2) HIV-P, and (3) an extension of HIV-P to osseous necrosis. Two cases of osseous destruction attending HIV-P are reported, one of which led to initial diagnosis of HIV infection. They represent the final stage of disease progression with localized necrosis of gingiva, periodontium, and alveolar bone.

Skeletal remains are the only source of the genetic material of decomposed organisms or once-lived species. Unlike, soft tissues they are highly mineralized, and their anatomical and morphological structure prevents their deformation in the presence of adverse environmental factors. Therefore, bones and teeth protect the Deoxyribonucleic Acid (DNA) inside them.

Background: Heterozygous TRPV4 mutations cause a group of skeletal dysplasias characterized by short stature, short trunk, and skeletal deformities.
Objective: The aim of this study is to compare the natural history of clinical and radiologic features of patients with different TRPV4-related skeletal dysplasias.
Materials And Methods: Thirteen patients with a mutation in TRPV4 were included in the study, and 11 were followed for a median of 6.

Reports of proteins in fossilized bones have been a subject of controversy in the scientific literature because it is assumed that fossilization results in the destruction of all organic components. In this paper, a novel combination of analytical techniques is used to address this question for an exceptionally well-preserved sacrum excavated from the Upper Cretaceous strata of the South Dakota Hell Creek Formation. Cross-polarized light microscopy (XPol) shows birefringence consistent with collagen presence.
