Promotor hypermethylated genes: Prospective diagnostic biomarkers in oral cancerogenesis.

Unlabelled: The advancements in epigenetics of oral squamous cell carcinoma (OSCC), are made in regard to DNA hypermethylation of MGMT, DAPK, ECAD (E-cadherin) and p16, as an important component of oral carcinogenesis and new potential biomarkers in molecular diagnostic strategies. The objective of the study was to evaluate the methylation status of the proposed genes and their possible role in the tumor genesis and diagnosis of OSCC.

Materials And Methods: From sixty surgically treated and molecularly analyzed patients, we obtained three groups of bioptical materials: tumor, normal contralateral and healthy tissues.

In vivo effects of geranylgeraniol on the development of bisphosphonate-related osteonecrosis of the jaws.

Background: Bisphosphonate-related osteonecrosis of the jaws (BRONJ) is a complication of the bisphosphonate (BP) treatment and its pathopysiology is still not fully understood. The existing preventive and treatment options require updates and more attention. Geranylgeraniol (GGOH) so far demonstrated an increased activity and viability of the cells previously treated with zoledronic acid (ZA).

Spinal accessory nerve preservation in modified neck dissections: surgical and functional outcomes.

The spinal accessory nerve (SAN) or XI cranial nerve is frequently encountered during neck surgery, and as such is at risk of iatrogenic injury, resulting in "shoulder syndrome". Modified neck dissection (MND) with preservation of the SAN is based on desire to minimise the functional deformity associated with section of the eleventh nerve. The aim of this study was to analyse the intra-operative variations of the spinal accessory nerve pathway and to evaluate shoulder dysfunction postoperatively.
