HETEROTOPIC OSSIFICATION IN ACETABULAR FRACTURES: SYSTEMATIC REVIEW AND META-ANALYSIS OF PROPHYLAXIS.

Objective: Heterotopic ossification is defined as the formation of trabecular bone in soft tissues. It is a common complication after surgical treatment of acetabular fractures. However, its prophylaxis and treatment are still controversial.

Toward a New Era for the Management of Circulating Tumor Cells.

Circulating tumor cells (CTCs) are malignant cells separate from primary tumors, which can migrate through the peripheral blood, colonize other tissues, and lead to the formation of metastases. The first description of CTCs dates back to 1869 when Thomas Ashworth recognized malignant cells similar to the ones of the primary tumor in the blood vessels of an autopsied patient with metastatic cancer. Currently, CTCs have been identified in various types of cancer and have been recognized for their clinical value in the prediction of prognosis, diagnosis of minimal residual diseases, assessment of tumor sensitivity to anticancer drugs, and personalization of therapies.

Orbital exenteration for sinonasal malignancies: indications, rehabilitation and oncologic outcomes.

Purpose Of Review: Review the recent literature regarding the management of orbital invasion in sinonasal malignant tumors.

Recent Findings: There is a recent trend in preserving the orbit in cases of minimal invasion of periosteum and limited periorbit involvement, as well as in presence of good response to neoadjuvant chemotherapy, mainly in squamous cell carcinoma and neuroendocrine histologies.

Summary: The decision about orbital exenteration in cases of sinonasal malignancies is facilitated if the patient already has clear clinical signs of intraconal invasion such as visual loss, restriction of ocular mobility or infiltration of the eyeglobe.
