Button Osteoma: A Review of Ten Cases

Causative effects of cranial depression fractures: A case study of structural violence and social vulnerability within the Mississippi state asylum

Cranial depression fractures (CDFs) are often associated with violence in a forensic and bioarchaeological context. Interpretations of CDFs, using a structural vulnerability framework, allow for examination of possible socioeconomic and sociocultural factors that influence an individual's life history. Placement of CDFs in relation to traumatic brain injuries (TBIs) and their potential connections to structural violence become essential for analysis. This case study presented Burial 49 from the Mississippi State Lunatic Asylum (MSA). Burial 49 was an adult individual (probable male) who exhibited antemortem trauma to the left parietal bone with an associated CDF. The injury location had the potential to cause a variety of neurological and developmental issues, including difficulty understanding spoken/written language. This case study demonstrates how CDFs, structural violence, and social vulnerabilities might have contributed to an increased risk of MSA admittance and provide context for why this individual was marginalized.

Imaging Review of Pediatric Benign Osteocytic Tumors and Latest Updates on Management

Pediatric benign osteocytic tumors include osteoma, enostosis, osteoid osteoma, and osteoblastoma. In pediatric populations, benign bone tumors are more common than malignancies. Benign osteocytic tumors may have a unique clinical presentation that helps narrow the differential diagnosis. A systemic imaging approach should be utilized to reach the diagnosis and guide clinicians in management. Radiographs are the most prevalent and cost-effective imaging modality. Cross-sectional imaging can be utilized for tissue characterization and for evaluation of lesions involving complex anatomical areas such as the pelvis and spine. Computed Tomography (CT) is the modality of choice for diagnosis of osteoid osteoma. CT scan can also be utilized to guide radiofrequency ablation, which has been found to be highly effective in treating osteoid osteoma and osteoblastoma. Enostosis is a no-touch lesion. Osteoma is commonly located in the paranasal sinuses. Osteoma needs an excision if it causes complications due to a mass effect.

The exceptional finding of Locus 2 at Dehesilla Cave and the Middle Neolithic ritual funerary practices of the Iberian Peninsula

There is a significant number of funerary contexts for the Early Neolithic in the Iberian Peninsula, and the body of information is much larger for the Late Neolithic. In contrast, the archaeological information available for the period in between (ca. 4800-4400/4200 cal BC) is scarce. This period, generally called Middle Neolithic, is the least well-known of the peninsular Neolithic sequence, and at present there is no specific synthesis on this topic at the peninsular scale. In 2017, an exceptional funerary context was discovered at Dehesilla Cave (Sierra de Cádiz, Southern Iberian Peninsula), providing radiocarbon dates which place it at the beginning of this little-known Middle Neolithic period, specifically between ca. 4800-4550 cal BC. Locus 2 is a deposition constituted by two adult human skulls and the skeleton of a very young sheep/goat, associated with stone structures and a hearth, and a number of pots, stone and bone tools and charred plant remains. The objectives of this paper are, firstly, to present the new archaeological context documented at Dehesilla Cave, supported by a wide range of data provided by interdisciplinary methods. The dataset is diverse in nature: stratigraphic, osteological, isotopic, zoological, artifactual, botanical and radiocarbon results are presented together. Secondly, to place this finding within the general context of the contemporaneous sites known in the Iberian Peninsula through a systematic review of the available evidence. This enables not only the formulation of explanations of the singular new context, but also to infer the possible ritual funerary behaviours and practices in the 5th millennium cal BC in the Iberian Peninsula.

Multiple osteomata from medieval Tuscany, Italy (ca. 10th-12th AD)

OBJECTIVE

To explore the possible etiology of multiple osteomata on a skull and long bones from an individual from a medieval site in Tuscany, Italy.

MATERIALS

Human skeletal remains dating to the 10^th-12^th century AD from the parish church of S. Pietro in Pava, in the province of Siena (Tuscany, Central Italy).

METHODS

Macroscopic and imaging analyses (Cone Beam Computed Tomography).

RESULTS

Nine round-shaped new bone formations are observed on a female individual aged 40-50 years. The lesions have a smooth surface and range from 2.2-6 mm in diameter.

CONCLUSIONS

Cone Beam Computed Tomography confirmed that the lesions were composed of compact bone. Macroscopic and radiological features suggest the presence of nonsyndromic multiple osteomata.

SIGNIFICANCE

Single cranial osteomata are commonly observed in osteoarchaeological remains, but multiple osteomata are rare and might assist in our understanding of neoplastic conditions in the past.

LIMITATIONS

The lack of soft tissues prevents the diagnosis of complex disorders, such as the Gardner syndrome, which is characterised by multiple osteomata and polyposis of the colon.

SUGGESTIONS FOR FURTHER RESEARCH

Careful investigation and reporting of all neoplastic lesions in ancient human remains in order to increase our knowledge about the etiology in past human populations.
