Abstract
BACKGROUND ADAR1 is an enzymatic protein, which catalyzes a RNA editing reaction by converting Adenosine to Inosine, and its expression has been found to be dysregulated in many cancer types. The aim of this study was to analyze the expression of ADAR1 in oral squamous cells carcinoma. METHODS In order to analyze the ADAR1 mRNA expression, data from The Cancer Genome Atlas (TCGA) database were downloaded and analyzed. In addition, immunohistochemistry analysis was performed on an institutional database including 46 samples of oral squamous cell carcinoma in a tissue microarray (TMA). RESULTS No statistically significant correlation linked the mRNA ADAR1 expression to any clinic-pathological variables in the TCGA database. Immunohistochemistry analysis of ADAR1 showed different expressions between normal mucosa and tumor tissue. Focusing on the subcellular localization, the nuclear expression of ADAR1 correlated with higher grading of differentiation (ρ = 0.442; P-value = 0.002); the general expression of ADAR1 either in cytoplasm or in nuclei, correlated with the Gender of patients (Cytoplasm expression: ρ = -0.295; P-value = 0.049; while for nuclear expression: ρ = +0.374; P = 0.011); cytosol expression resulted to be an independent protective prognostic factor (HR = 0.047; C.I. 95% 0.007-0.321; P-value = 0.002). CONCLUSION Higher expression of ADAR1 into the cytoplasm resulted to be an independent prognostic factor. In order to understand ADAR1 role in cancer, further studies should be performed, in bigger cohort and under a bio-molecular point of view.

High PD-L1 expression in the tumour cells did not correlate with poor prognosis of patients suffering for oral squamous cells carcinoma: A meta-analysis of the literature. Cell Prolif 2018; 52:e12537. [PMID: 30443950 PMCID: PMC6495964 DOI: 10.1111/cpr.12537] [Citation(s) in RCA: 42] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2018] [Revised: 08/13/2018] [Accepted: 08/30/2018] [Indexed: 12/19/2022] Open
Abstract
OBJECTIVES Oral cancer represents one of the most common malignancies in humans. Its prognosis is still poor, despite the most recent improvements in therapies. An increasing attention is placed on the role of programmed death ligand 1 (PD-L1) in the tumour immunity and its potential function as a marker for tumour prognosis. Whether PD-L1 expression is a prognostic factor for the poor outcomes in oral squamous cell carcinoma is still controversial. This study aimed to investigate, through a meta-analysis, a potential correlation between PD-L1 expression and the prognostic outcomes in patients with oral squamous cell carcinoma. MATERIALS AND METHODS The studies were identified by searching PubMed, SCOPUS, Web of Science and were assessed by two of the authors. After the selection process, 11 articles met eligibility criteria and were included in the meta-analysis. Quality assessment of studies was performed according to the REMARK guidelines, and the risk of biases across studies was investigated through Q and I2 tests. Meta-analysis was performed to investigate the association between the PD-L1 expression either overall survival (OS), disease-free survival (DFS), disease-specific survival (DSS), gender and lymph node metastasis. RESULTS A total of 1060 patients were analysed in the 11 studies included in the meta-analysis. Pooled analysis revealed that the expression of PD-L1 did not correlate with poor OS (HR, 0.60; 95% CI: [0.33, 1.10]; P = 0.10), DFS (HR, 0.62; 95% CI: [0.21, 1.88]; P = 0.40), DSS (HR, 2.05; 95% CI: [0.53, 7.86]; P = 0.29 and lymph node metastasis (HR, 1.15; 95% CI: [0.74, 1.81]; P = 0.53). Furthermore, results of the meta-analysis showed that high expression of PD-L1 is two times more frequent in female patients (OR, 0.5; 95% CI: [0.36, 0.69]; P < 0.0001) compared to males. For all the three outcomes analysed, a high rate of heterogeneity was detected (I2 > 50%). DISCUSSION High PD-L1 expression did not correlate with poor prognosis of patients suffering for oral squamous cell carcinoma. Studies published on the topic showed a significant variation in results, limiting the use of PD-L1 expression by immunohistochemistry as prognostic biomarker in clinical practice.

Abstract
Fermented wheat germ extract (FWGE; trade name AVEMAR) is a natural compound derived from industrial fermentation of wheat germ. Its potential anticancer properties has emerged from recent studies. The aim of this systematic review is to summarize the data available in the scientific literature concerning the in vitro activity of FWGE on malignant cells. A systematic review of English articles in electronic databases has been performed. The primary outcomes of the review regarded types of cancer cell lines subjected to the investigation and the main results concerning cell viability, proliferation, and apoptosis observed within the studies. Sixteen articles were included in the final qualitative analysis. Various types of cancer cells treated with FWGE have been analyzed, showing mainly cytotoxic effects, alteration of the cell cycle, antiproliferative effects, and induction of apoptosis. FWGE can be a promising drug component in cancer treatment; however, further in vitro and in vivo studies are necessary to prove its effectiveness and safety in humans.

Abstract
The oral tongue is the most common site for tumours within the oral cavity. Despite intense research, there has been no improvement in the survival rate for patients with oral tongue squamous cell carcinoma (OTSCC) during the last decades. Differences between oral cancer patients based on ethno-geographical distribution have been reported. The present study used immunohistochemistry to evaluate commonly used markers of cancer cell phenotypes, E-cadherin, β-catenin and cytokeratins 5 and 19, in 120 patients with OTSCC. To evaluate the impact of ethnicity, patients from Sweden and Italy were included. A higher proportion of Swedish patients exhibited high expression of E-cadherin in their tumours (P=0.039), and high levels of E-cadherin in Swedish OTSCC patients that had succumbed to their disease were associated with poor prognosis. These data demonstrated differences in the pathological characteristics of OTSCC between two different European populations. The findings emphasise the need to take ethnicity/geographical location of patients into account when comparing results from different studies of OTSCC.

Abstract
Medication-related osteonecrosis of the jaw (MRONJ) is a serious adverse reaction of antiresorptive and antiangiogenic agents; it is a potentially painful and debilitating condition that can considerably affect the quality of life of patients. Furthermore, even if its epidemiology and pathogenesis have still not been fully clarified, several risk factors related to MRONJ have been recognized in prevention protocols. Three main risk factors are as follows: (i) the type of ONJ-related medications: antiresorptive (e.g., Bisphosphonates, Denosumab) and antiangiogenic drugs (e.g., Bevacizumab, Sunitinib); (ii) the category of patient at MRONJ risk: cancer versus non-cancer patient; (iii) the typologies and timing of dental treatments (e.g., before, during, or after the drug administration). The aim of this paper is to describe the new paradigm by the Italian Society of Oral Pathology and Medicine (SIPMO) on preventive dental management in patients at risk of MRONJ, prior to and during/after the administration of the aforementioned ONJ-related drugs. In reducing the risk of MRONJ, dentists and oral hygienists are key figures in applying a correct protocol of primary prevention for pre-treatment and in-treatment patients. However, the necessity of a multidisciplinary standardized approach, with a sustained dialogue among specialists involved, should be always adopted in order to improve the efficacy of preventive strategies and to ameliorate the patient's quality of life.

Abstract
Survivin is a well-known protein involved in the inhibition of apoptosis in many different cancer types. The aim of this study was to perform an integrated bioinformatic and histologic analysis in order to study the expression and prognostic role of Survivin and its related gene BIRC5 in oral cancer. Publicly available databases were accessed via Gene Expression Omnibus and Oncomine, in addition raw data from The Cancer Genome Atlas (TCGA) were also obtained in order to analyze the rate of gene mutation, expression and methylation in patients with oral squamous cells carcinoma (OSCC). Immunohistochemistry (IHC) was also performed in order to evaluate the nuclear and cytoplasmic expression of Survivin and their correlation with cell proliferation in samples from OSCC patients. Results of this study revealed that Survivin is rarely mutated in OSCC samples and upregulated when compared to non-cancerous tissue. A negative correlation between the methylation of the island cg25986496 and BIRC5 mRNA expression was detected from TCGA data. IHC staining revealed that cytoplasmic (and not nuclear) expression of Survivin is associated with poor overall survival in OSCC patients, while the nuclear expression correlates with higher proliferation rate. In addition, data from TCGA database revealed that BIRC5 gene expression is an independent prognostic factor for OSCC patients.

Abstract
Background Mandibular condylar fractures commonly occur after trauma and account for 25 to 35% of all mandibular fractures; its appropriate therapy still remains a point of controversy in children. The purpose of this paper is to describe the treatment of an 11-years-old male patient affected by neck-condylar fracture as result of trauma in evolutive age. Methods No surgical treatment was performed. A functional therapy was applied with a jaw splint. A closed treatment for mandibular condyle fractures was preferred because the amount of condylar displacement wasn’t considerable. Results The early treatment with functional therapy generated a functional adaptation of the condyle in the glenoid fossa and a normal mandibular function. After a 12-month follow-up the fracture resolution and an optimal condylar position were recorded. Conclusions The current case report and literature review showed that non-surgical therapy of neck-condylar fracture in a child with lower resin splint can restore mandibular movements and aesthetics. Facial growth after one year treatment resulted normal. A conservative treatment may be appropriate for children in selected cases with minimally displaced condyle.

Abstract
Oral squamous cell carcinoma (OSCC) is one of the most aggressive and deadliest tumors worldwide. The aryl hydrocarbon receptor (AHR) is a nuclear transcription factor known as a dioxin receptor and mediates the toxic effects of industrial contaminants. In addition, AHR has been implicated in multiple cellular processes and its expression has been shown to play a critical role in tumorigenesis, including human oral cancer cell lines. In the present study, we evaluated the expression of AHR/HSP-90 in 25 formalin‑fixed, paraffin-embedded human oral cancer specimens by IHC analysis. CYP1A1 expression was regarded as an AHR reporter gene. The data indicated a complete correlation between AHR expression and cancer grade enabling us to propose AHR as a prognostic marker of oral cancer. Moreover, in OSCC cell line CAL27, we observed the modulatory effect of polydatin, a widespread natural substance and direct precursor of resveratrol, on AHR expression. A computational approach was performed to predict the site of interaction of polydatin on the AHR surface. Our studies confirm the involvement of AHR signaling in the clinicopathological specimens of oral cancer and suggest the use of polydatin for oral cancer prevention.

Abstract
OBJECTIVE The aim of this study was to systematically review the literature to determine: (a) the malignant transformation rate (TR) of oral lichen planus (OLP) and its risk factors; (b) whether or not oral lichenoid lesions (OLL) have a different malignant TR. MATERIALS AND METHODS PubMed, Scopus, and Web of Science were used as search engines: only observational, full-length, English language studies were investigated. PRISMA protocol was used to evaluate and present results. PROSPERO registration code is CRD42016048529. RESULTS Among 7,429 records screened, only 21 were included in this review. Ninety-two of 6,559 patients developed oral squamous cell carcinoma, with an overall TR of 1.40% (1.37% for OLP and 2.43% for OLL), an annual TR of 0.20%. Female gender, red clinical forms, and tongue site seem to slightly increase the transformation risk. CONCLUSIONS This systematic review confirms that both OLP and OLL, the latter with a slightly higher TR, may be considered potentially malignant disorders and suggest that erosive type, female gender and tongue site should be considered as risk factors for OLP transformation. Major efforts should be done to establish strict clinical and histological criteria to diagnose OLP and to perform sounder methodological observational studies.

Abstract
Adamatiades-Behçet disease (BD) is a primary systemic vasculitis of unknown origin, that may involve blood vessels of all sizes. The clinical hall-mark of the disease are recurrent oral aphthous ulcers, painful, sharply margined and often associated with recurrent genital ulcers. A variety of skin lesions, such as erythema nodosum-like nodules and purpuric lesions are frequently observed. Less common manifestations of BD include thrombophlebitis, central nervous system and ocular inflammation which, however, may impact significant morbidity and mortality. The etiology is unknown, although genetic factors, infectious agents, oral and salivary microbioma, and immunologic mechanisms are implicated and studied. Topical and eventually systemic corticosteroids are the choice treatment.

Abstract
Bone loss and fractures are consequences of aging, diseases or traumas. Furthermore the increased number of aged people, due to the rise of life expectancy, needs more strategies to limit the bone loss and regenerate the lost tissue, ameliorating the life quality of patients. A great interest for non-pharmacological therapies based on natural compounds is emerging and focusing on the oligostilbene Polydatin, present in many kinds of fruits and vegetables, when resveratrol particularly in red wines. These molecules have been extensively studied due to their antioxidant and anti-inflammatory effects, showing more recently Resveratrol the ability to enhance osteogenic differentiation and bone formation. However, the clinical applications of Resveratrol are limited due to its low bioavailability and rapid metabolism, while its natural glycosilated precursor Polydatin shows better metabolic stability and major abundance in fresh fruits and vegetables. Nevertheless the role of Polydatin on osteogenic differentiation is still unexplored. Mesenchymal stem cells (MSCs) from dental tissues, such as dental bud stem cells (DBSCs), are able to differentiate toward osteogenic lineage: thus we investigated how Resveratrol and Polydatin influence the differentiation of DBSCs, eventually affecting bone formation. Our results showed that Polydatin increases MSCs osteogenic differentiation sharing similar properties with Resveratrol. These results encourage to deepen the effects of this molecule on bone health and its associated mechanisms of action, wishing for the future a successful use in bone loss prevention and therapy.

Abstract
OBJECTIVES Oral squamous cell carcinoma (OSCC) is the most common malignancy of oral cavity. Despite advances in therapeutic approaches, the 5-year survival rate for oral cancer has not improved in the last three decades. Therefore, new molecular targets for early diagnosis and treatment of OSCC are needed. In the present study, we focused on the enzyme nicotinamide N-methyltransferase (NNMT). We have previously shown that enzyme expression is upregulated in OSCC and NNMT knockdown in PE/CA PJ-15 cells significantly decreased cell growth in vitro and tumorigenicity in vivo. MATERIAL AND METHODS To further explore the role of the enzyme in oral cancer cell metabolism, HSC-2 cells were transfected with the NNMT expression vector (pcDNA3-NNMT) and the effect of enzyme upregulation on cell proliferation was evaluated by MTT assay. Subsequently, we investigated at molecular level the role of NNMT on apoptosis and cell proliferation, by exploring the expression of β-catenin, survivin, and Ki-67 by real-time PCR. Moreover, we performed immunohistochemistry on 20 OSCC tissue samples to explore the expression level of NNMT and survivin ΔEx3 isoform. RESULTS Enzyme upregulation significantly increased cell growth in vitro. Moreover, a positive correlation between NNMT and survivin ΔEx3 isoform expression levels was found both in HSC-2 cells and in OSCC tissue samples. CONCLUSION Taken together, our results indicate a possible involvement of NNMT in the proliferation and tumorigenic capacity of OSCC cells and seem to suggest that the enzyme could represent a potential target for the treatment of oral cancer. CLINICAL RELEVANCE The involvement of NNMT in cell growth and anti-apoptotic mechanisms seems to suggest that this enzyme could be a new therapeutic target to improve the survival of OSCC patients.

Abstract
Squamous cell carcinoma of the head and neck, SCCHN, is a heterogeneous group of tumours
not only concerning the site of origin but also regarding aetiology. The 5-year survival for the
whole group of SCCHN tumours has not significantly improved over the last 20-25 years. Apart from
tumour spread to lymph nodes, N status, gains and losses of specific chromosomes are the only factors
shown to be independent prognostic markers for these tumours. Worldwide, an increasing number
of people ≤ 40 years are seen being affected by tongue SCC, the most common tumour within the
SCCHN group. Even without any clinical signs of metastasis, up to 30% of all tongue SCC have histologically
detectable spread to lymph nodes.
In this mini review, field cancerization, tumour microenvironment, the so called EMT (epithelial
mesenchymal transition) process and the role of viruses in development of SCCHN are discussed as
well as potential new therapeutic targets.
For the group of tongue SCC, with the increasing incidence seen in young patients and particularly
women, new data with impact on prognosis and treatment are urgently needed. But as long as data
from the analyses of several sub sites are presented as valid for the whole group of tumours, this vital
point is missed.

Abstract
The use of nutraceuticals as protection drugs against chronic diseases gained a vast success.
Many studies found that nutraceuticals may reduce the tumorigenic actions of carcinogens, inhibiting
the adhesion and proliferation of tumor cells.
Genistein is a natural isoflavone preventing osteoporosis, menopause problems and heart diseases. It
is also known in China and Japan for its anticancer properties.
The available treatment protocols for Head and neck squamous cell cancer (HNSCC) have led to poor
results and new therapies are necessary.
In this paper, we will review anticancer therapeutic potential of genistein and in vitro and in vivo
studies that suggest its potential role in the treatments of HNSCC.

Abstract
AIMS The aim of the present work was to evaluate the dentoskeletal effects of swallowing occlusal contact intercept appliance (SOCIA) III in pseudo Class III malocclusion treatment. MATERIALS AND METHODS Thirty-six patients (mean age: 9.46 years old) with pseudo-Class III malocclusion and 22 pseudo-Class III untreated controls (mean age: 8.7 years old) were selected and examined. All patients presented with a cervical stage CS2, CS3, or CS4. Patients with CS5 were not enrolled in the study. Cephalometric analysis was performed before phase 1 treatment (T1) and immediately following phase 2 treatment (T2). STATISTICAL ANALYSIS Paired t-test and independent t-test. RESULTS SOCIA III had skeletal and dental effects. The main effects of SOCIA III were on the midface with an effective increase of the sagittal growth (cranial base P < 0.001, anterior cranial base (ACB) P < 0.001, and maxilla growth P < 0.001) and vertical growth (anterior facial height P < 0.001). The effects of SOCIA on the mandible were a control of mandibular postrotation (P = 0.82) and the sagittal growth (P < 0.007). At the end of the treatment, a normal overjet was achieved (P < 0.001). CONCLUSIONS The SOCIA III effects are resumed as follow: (a) an effective maxillary sagittal increase on the sagittal plane; (b) a vertical mandibular control; (c) a resolution of overjet; (d) no increase of overbite; (e) a stimulation of ACB growth.

Abstract
Cells from dental tissues have a mesenchymal stem cell (MSC) phenotype, are multipotent and can differentiate into osteoblastic cells, as we have previously found. MSCs, due to their tumor‑homing ability, are currently being used as cell‑based delivery systems for cancer protein therapeutics, such as the TNF‑related apoptosis‑inducing ligand (TRAIL). In the present study we revealed that dental pulp stem cells (DPSCs) expressed TRAIL to a greater extent when they were differentiated into the osteoblastic lineage. TRAIL affected the viability of undifferentiated DPSCs, while osteoblastic differentiated DPSCs were not sensitive to TRAIL. The expression trend of TRAIL receptors underwent changes during the osteoblastic differentiation of DPSCs exhibiting low DcR2 and high DR5 levels in the undifferentiated DPSCs and an opposite scenario was presented in the differentiated cells. The sensitivity of the undifferentiated DPSCs to the TRAIL‑apoptotic effect was also associated with low levels of intracellular anti‑apoptotic proteins, such as c‑FLIP, XIAP and the activation of caspase‑8 and ‑3. DPSC‑differentiated osteoblasts expressing high TRAIL levels were capable to affect the cell viability of the human myeloma cell line H929, thus representing an effective anticancer therapeutic method.

Abstract
The aim of this systematic review and meta-analysis was to compare the clinical efficacy of two routes of dexamethasone administration in reducing the postoperative sequelae after third molar extraction. Electronic databases (PUBMED, SCOPUS and EBSCO library) were screened in order to find both randomized and non-randomized clinical trials that directly compare the submucosal intraoral or the intramuscular extraoral administration of dexamethasone. No restriction about year of publication was imposed. About 340 titles and abstracts were screened independently by two authors. Of these [340 titles], only 4 randomized clinical trials met the inclusion criteria and were included in the meta-analysis. No statistical differences in postoperative pain, swelling and trismus were recorded comparing the intraoral submucosal and the extraoral intramuscular injection of dexamethasone in an extra-oral site.

Abstract
Purpose Tongue cancer is an extremely aggressive disease and is characterized by a poor prognosis. It is a complex disease to treat and current therapies have produced mediocre results with many side effects. Some facts suggest that natural essences can support traditional cancer therapy by carrying out a synergistic function with chemotherapy. Therefore, we evaluated the antitumor effects of genistein on tongue carcinoma cells. Methods Genistein 20, 50 and 100 µM were used for 24, 48 and 72 hours on 3 tongue carcinoma cell lines. xCELLigence system was used to evaluate the effects on cell adhesion, proliferation and to calculate IC50 values. Both MTT assay and Trypan blue assay were used to evaluate alterations in cell viability, scratch assay for cell migration and Western blot analysis for expression of some proteins. Results Cell adhesion was inhibited especially between 20 and 50 µM of genistein treatment. Proliferation was reduced by 50% for treatments with 20 µM at 24 hours, with 20 or 50 µM at 48 and 50 µM at 72 hours (P<0.0001). Viability tests confirmed a proportional reduction in concentration of genistein and duration of treatments. Even cell migration was reduced significantly (P<0.001). Genistein down-regulates vitronectin, OCT4 and survivin. Conclusion This in vitro study clarifies the anti-tumor effect of genistein on tongue carcinoma. In vivo studies are needed to confirm these data and develop a suitable delivery system that is capable of acting directly on tumor.
