Soft tissue abnormalities in the congenital limb malformation radial dysplasia (RD): Their clinical impact and treatment significance

Journal of Anatomy, EarlyView.
We review the characteristic changes to the limb soft tissue and neurovascular abnormalities that have been described in the congenital limb birth defect, Radial Dysplasia. These include consistent changes in muscle anatomy or absence of specific muscles, persistent median arteries and absent radial arteries and consistent alterations in neural ...

Postcranial anatomy of the Miocene hippopotamoids of Toros‐Menalla, Chad

Journal of Anatomy, EarlyView.
We establish a framework for the identification of postcranial remains in hippopotamoids by describing and comparing for the first time two late Miocene hippopotamoids from Toros‐Menalla, Chad (Hexaprotodon garyam, an early hippopotamid, and Libycosaurus bahri, the last African anthracothere) with the common hippopotamus.

A bristle‐nosed Jurassic ray‐finned fish (Actinopterygii) bears true dermal odontodes on its snout

Journal of Anatomy, EarlyView.
Teeth show extreme diversity, including tooth‐like dermal odontodes or “skin teeth” in many extant fishes. We describe the anatomy of enlarged tubercles on the snout of Redfieldius, an extinct early Jurassic fish. We found that the tubercles in Redfieldius are dermal odontodes that evolved independently from those of living species. Abstract Comparison

Computed tomography reveals multiple origins of extreme caudal vertebral pneumaticity in sauropod dinosaurs

Journal of Anatomy, EarlyView.
Here, we present novel CT scan data of caudal vertebrae of six Middle–Late Jurassic sauropods, representing several eusauropod lineages. We synthesise these new data with a comprehensive critical appraisal of purported external and internal evidence for caudal vertebral PSP in Sauropodomorpha.

CHARGE Syndrome: A Narrative Review and Update on Diagnosis, Assessment and Management

Journal of Paediatrics and Child Health, EarlyView.
ABSTRACT Background CHARGE syndrome (CS) is a rare multisystemic genetic condition caused by a pathogenic variant in the DNA‐binding protein‐7 CHD7 gene. The condition affects the development of neural crest cells, which give rise to craniofacial structures, cranial nerves, ears, eyes and the heart, resulting in diverse and complex clinical features ...

Stem Cells From Dental Pulp, Periodontal Tissues, and Other Oral Sources: Biological Concepts and Regenerative Potential

Journal of Periodontal Research, EarlyView.
A graphical abstract recapping the different sources of dental, periodontal, and other oral‐derived mesenchymal stromal cells (MSCs) and their regenerative mechanisms and potentials. The review's article findings bridge fundamental biological science with translational advances, highlighting the significance of MSCs in craniofacial regenerative ...

Autogenous Demineralized Dentin Graft–Based Strategies With or Without I‐PRF and Metronidazole for Ridge Preservation in Infected Sockets: A Randomized Clinical Trial

Journal of Periodontal Research, EarlyView.
This randomized controlled trial evaluated the efficacy of demineralized dentin graft (DDG) combined with injectable platelet‐rich fibrin (I‐PRF) and metronidazole (MTZ) versus DDG with or without I‐PRF in alveolar ridge preservation (ARP) of infected extraction sockets.

Hemangiopericytoma of the spinal canal

World Neurosurgery, 1981
A case of hemangiopericytoma of the spinal canal is presented, which, added to the 9 cases reported in the literature, confirms the existence of this rare tumoral entity involving the vertebral column, with extension into the spinal canal, and its preferential localization in the cervical spine.

Beyond the Spinal Canal

Radiologic Clinics of North America, 2019
Cross-sectional spinal imaging is common, and extraspinal findings are often incidentally identified during interpretation. Although some of these findings may cause symptoms that mimic a spinal disorder, the majority are entirely asymptomatic and incidental.

Paragangliomas of the spinal canal

Surgical Neurology, 1983
Paragangliomas are tumors arising in the paraganglia and rarely occur in the spinal canal. In the literature, 11 such cases have been reported. We present 7 additional cases, 3 of which were epidural in location in contrast to previously described intradural cases. The problems of histological diagnosis of these tumors are discussed.
