Abstract
The epidemiology of HIV-related oral disease in industrialized nations has evolved following the initial manifestations described in 1982. Studies from both the Americas and Europe report a decreased frequency of HIV-related oral manifestations of 10–50% following the introduction of HAART (highly active antiretroviral therapy). Evidence suggests that HAART plays an important role in controlling the occurrence of oral candidosis. The effect of HAART on reducing the incidence of oral lesions, other than oral candidosis, does not appear as significant, possibly as a result of low lesion prevalence in industrialized countries. In contrast to other oral manifestations of HIV, an increased prevalence of oral warts in patients on HAART has been reported from the USA and the UK. HIV-related salivary gland disease may show a trend of rising prevalence in the USA and Europe. The re-emergence of HIV-related oral disease may be indicative of failing therapy. A range of orofacial iatrogenic consequences of HAART has been reported, and it is often difficult to distinguish between true HIV-related oral disease manifestations and the adverse effects of HAART. A possible association between an increased risk of oral squamous cell carcinoma and HIV infection has been suggested by at least three epidemiological studies, with reference to the lip and tongue. These substantial and intensive research efforts directed toward enhancing knowledge regarding the orofacial consequences of HIV infection in the industrialized nations require dissemination in the wider health care environment.

Abstract
Tissue repair is an integral component of cancer treatment (e.g., due to surgery, chemotherapy, radiation). Previous work has emphasized the immunosuppressive effects of tumors on adaptive immunity and has shown that surgery incites cancer metastases. However, the extent to which and how tumors may alter the clinically-relevant innate immune process of wound healing remains an untapped potential area of improvement for treatment, quality of life, and ultimately, mortality of cancer patients. In this study, 3.5 mm full-thickness dermal excisional wounds were placed on the dorsum of immunocompetent female mice with and without non-malignant flank AT-84 murine oral squamous cell carcinomas. Wound closure rate, inflammatory cell number and inflammatory signaling in wounds, and circulating myeloid cell concentrations were compared between tumor-bearing and tumor-free mice. Tumors delayed wound closure, suppressed inflammatory signaling, and altered myeloid cell trafficking in wounds. An in vitro scratch “wounding” assay of adult dermal fibroblasts treated with tumor cell-conditioned media supported the in vivo findings. This study demonstrates that tumors are sufficient to disrupt fundamental and clinically-relevant innate immune functions. The understanding of these underlying mechanisms provides potential for therapeutic interventions capable of improving the treatment of cancer while reducing morbidities and mortality.

Abstract
BACKGROUND Nowadays, human papillomavirus (HPV) infection becomes the main risk factor for head and neck cancer development. In Thailand, the related role of this viral infection to head and neck cancer is still unknown and not well established. OBJECTIVE To identify different characteristics of oral cavity and oropharyngeal cancer, and to determine the HPV-associated prevalence of these two tumor types in Thailand, which is unlike the Western countries. MATERIAL AND METHOD Between 2010 and 2012, a cross-sectional study was performed in 23 oral cavity and 23 oropharyngeal cancer patients. HPV genome was studied in all of them from pathological confirmed fresh specimens. Risks of HPV infection were collected using self-reported questionnaire. RESULTS The prevalence of HPV-related oropharyngeal cancer was significantly noted in 26.09% (p = 0.009), while no demonstrable HPV-associated prevalence in oral cavity cancer. In addition, the routes of HPV infection were not identifiable. CONCLUSION Oral cavity and oropharygeal cancers are not only anatomically distinct, but also greatly differed in their characteristics and pathophysiology. The percentage of HPV-related tumors in Thailand is considerably low when compared to the Western countries. However, the impact on treatment modification cannot yet be universally applied.

Abstract
The dental problems of the elderly, though they may seem slight, can have far-reaching effects on both health and quality of life. The complexity and variety of potential physical and psychosocial problems of older citizens require a multidisciplinary management approach. Dental team members need to target appropriate resources outside of the dental office, and nondental care providers need to attend to dental needs as well as other more evident problems. Only in this way can we help to optimize the health and longevity of this ever-increasing segment of the population.

Abstract
OBJECTIVE To investigate the factors associated with oral infections in patients with oral cancer undergoing radiotherapy. METHODS Clinical data of 241 patients with oral cancer undergoing radiotherapy between March 2012 and May 2014 in sichuan cancer hospital were reviewed. Univariate and multivariate analyses were performed to determine the factors related to oral infection occurring in the patients. SPSS 17.0 software was used to analyze the data. RESULTS Ninety-three (38.59%) of 241 cases had oral infection. Among the 93 cases, 49 (52.69%) cases presented with fungal infections, 44 (47.31%) cases with bacterial infection, and 38 (40.86%) cases with mixed infection. Oral infection occurred since the fifth week after radiotherapy in 55 (59.14%) patients. Multivariate Logistic regression analysis showed that the risk factors for oral infection after radiotherapy were the late stage of cancer, poor oral health habits, the coexistence of multiple treatments, city dwellers and surgical history (all P<0.05). CONCLUSIONS Oral infections commonly occur in the late period of radiotherapy. The late stage of cancer, poor oral health habits, the coexistence of multiple treatments, city dwellers and surgical history are key risk factors for oral infection in patients with oral cancer undergoing radiotherapy.

Abstract
Diet is important for both quality of life (QoL) and survival of patients with oral cancer. Their intake of food is impeded by functional restrictions in chewing and swallowing. In the DÖSAK REHAB STUDY 1652 patients from 38 hospitals within the German-language area of Germany; Austria and Switzerland were examined with regard to functional and psychological variables having an impact on diet. Chewing and swallowing are correlated with mobility of the tongue and the mandible as well as opening of the mouth. Thirty five percent of the patients lost weight; 41% maintained their weight and 24% gained weight. The QoL of patients who were able to maintain their weight and of those who gained weight was significantly better than that of patients who lost weight. A normal diet was important for maintaining weight. Mashed food; liquid food and loss of appetite were closely associated with loss of weight; although it was possible for nutritional counseling and dietary support to be implemented particularly favorably in this respect. Due to problems with eating patients' strength deteriorated; thus restricting activity. Radiotherapy had a negative impact on diet and weight. It influenced sense of taste; dryness of the mouth; swelling and discomfort when ingesting food. Pain and scars in the region of the operation also cause patients to dislike hard; spicy and sour food. Support from a nutritional counselor in implementing a calorie-rich diet remedied this and such support needs to be integrated into patient management. The fact that a poor nutritional status is of such great importance is well-known; but what is often lacking is the systematic implementation of continued professional nutritional counseling over a long period of time; weight control and psycho-social support of the operated patients; particularly those who also have had radiotherapy.

Abstract
INTRODUCTION AND OBJECTIVES The facial artery musculomucosal (FAMM) flap is a good option for covering small and medium-sized defects in the oral cavity because of its similar tissue characteristics and easy implementation. METHODS We reviewed our results using this flap between 2006 and 2014. A total of 20 patients were included and 25 FAMM flaps were performed, 16 right (64%) and 9 left (36%) flaps. Five patients had simultaneous bilateral reconstructions. The indications for flap surgery were reconstruction after resection of tumours in the floor of the mouth (8 cases, 40%), tumours in other sites of the oral cavity (4 cases, 20%), mandibular osteoradionecrosis (4 cases, 20%), oroantral fistula (3 cases, 15%) and postoperative ankyloglossia (one case, 5%). RESULTS Reconstruction was successful in 92% of cases (n=23). Total flap necrosis occurred in one case and dehiscence with exposure of bone in another. Oral function and ingestion were satisfactory in all patients. CONCLUSIONS The facial artery musculomucosal flap is reliable and versatile for reconstruction of small and medium-sized intraoral defects. It allows functional reconstruction of the oral cavity with a low risk of complications.

Abstract
The fascia's and subcutaneous adipose tissue's impairment by mono or polymicrobial infection, which also can involve the skin and the muscles, is rarely seen in oro-maxillo-facial area. The present case report is presenting a case of necrotizing fasciitis in a patient who had a history of an invasive squamous cell carcinoma of the soft palate, with surgical treatment and with radiotherapy. He was admitted in our Clinic with malaise and subsequently developed a toxico-septic shock. Clinical symptoms, serological and bacteriological analysis and histopathological examination confirmed the diagnosis of necrotizing fasciitis (NF). The patient subsequently underwent a series of surgical reconstruction and aesthetic treatments because of the complications that had arised in the meantime. Postoperative evolution was favorable towards complete closure of the defect. The prognosis of this disease is generally reserved, the favorable evolution depending on the possibility of wound sterilization and the surgery is required despite its mutilating effect.

Abstract
INTRODUCTION Head and neck cancers are the most common cancers worldwide. It is estimated that approximately 90% of all head and neck cancers are represented by squamous cell carcinoma (SCC). There are many risk factors causing this type of cancer, including environmental factors and lifestyle choices, such as tobacco smoking or abusing alcohol. Other important risk factor include infectious factors. OBJECTIVE The aim of this study was to analyze the prevalence of BK and JC virus infections among patients with oral squamous cell carcinoma (OSCC). MATERIALS AND METHOD The correlation between BKV infection and OSCC, and correlation between BKV, OSCC, alcohol abuse, tobacco smoking, demographic data, pre-treatment staging, metastases of lymph node evidence, and grading, was analyzed. The study group consisted of 92 patients with squamous cell carcinoma (OSCC), 75 males, and 17 females, aged between 40 - 87 (average 56.8). All the patients underwent surgery and were not subjected to chemotherapy or radiotherapy prior to treatment. The analyzed samples were collected from paraffin sections. RESULTS BKV DNA was detected in 18.5% of patients with OSCC. In the control group, BKV DNA was detected in 3.3%. BKV DNA was statistically more frequently detected among patients with squamous carcinoma, compared to the control group (p<0.05). CONCLUSIONS The obtained results suggest that the BKV virus may play an important role in the development of oral squamous cell carcinoma.

Abstract
Overexpression of peroxiredoxin 1 (Prx1) has been observed in numerous cancers including oral squamous cell carcinoma (OSCC). The precise molecular mechanism of up-regulation of Prx1 in carcinogenesis, however, is still poorly understood. The objective of this study is to investigate the relationship between Prx1 and hypoxia, and potential mechanism(s) of Prx1 in OSCC cell line SCC15 and xenograft model. We treated wild-type and Prx1 knockdown SCC15 cells with transient hypoxia followed by reoxygenation. We detected the condition of hypoxia, production of reactive oxygen species (ROS), and expression and/or activity of Prx1, heme oxygenase 1 (HO-1) and nuclear factor-kappa B (NF-κB). We found that hypoxia induces ROS accumulation, up-regulates Prx1, increases NF-κB translocation and DNA binding activity, and down-regulates HO-1 in vitro. In Prx1 knockdown cells, the expression level of HO-1 was increased, while NFκB translocation and DNA binding activity were decreased after hypoxia or hypoxia/reoxygenation treatment. Moreover, we mimicked the dynamic oxygenation tumor microenvironment in xenograft model and assessed the above indices in tumors with the maximal diameter of 2 mm, 5 mm, 10 mm or 15 mm, respectively. Our data showed that tumor hypoxic condition and expression of Prx1 are significantly associated with tumor growth. The expression of HO-1 and NF-κB, and NF-κB DNA binding activity were significantly elevated in 15 mm tumors, and the level of 8-hydroxydeoxyguanosine was increased in 10 mm and 15 mm tumors, compared to those in size of 2 mm. The results from this study provide experimental evidence that overexpression of Prx1 is associated with hypoxia, and Prx1/NF-κB/HO-1 signaling pathway may be involved in oral carcinogenesis.

Abstract
Background Noradrenergic pathways and glucocorticoid-mediated signal pathways have been implicated in the growth and progression of oral cancer. Patients with oral neoplasms can have high psychological distress levels, but the effects of stress-related hormones on oral neoplasm growth are unknown. Methods We have investigated the relationships between pre-surgical measurements of psychological problems with Symptom Checklist-90-revised Inventory (SCL90-R), tumor histology, circulating blood catecholamine and glucocorticoid levels among 75 oral neoplasm patients, including 40 oral cancer patients and 35 benign oral tumor patients. Results The results showed that most dimension scores of SCL90-R did not show a significant difference between the two groups except depression (p = 0.0201) and obsessive-compulsion (p = 0.0093), with the scores for these symptoms being higher among oral cancer group versus the benign oral tumor group. The differences of total score, average score and other monomial factor scores were not statistically significant. The mean concentrations of catecholamine and glucocorticoid in peripheral blood of the oral cancer group were higher than those in benign oral tumor group (p<0.01). We also examined whether associations observed between biobehavioral measures and circulating blood catecholamine and glucocorticoid levels extended to other compartments in the oral cancer group. Conclusions These findings suggest that stress hormones may affect oral cancer behavior by influencing the tumor micro-environment though the circulating blood.

Abstract
A wide variety of lesions may manifest in the oral soft tissues that could be confusing and challenging for the clinicians. These lesions could be as simple as trauma-induced ulcers that need about 2 weeks to heal, to a more complicated situation such as oral cancer. The key points in developing diagnosis and a possible treatment plan may include a comprehensive oral examination, simple understanding of normal oral tissue features, and knowledge of common oral lesions. This will help in the development of a differential diagnosis of the oral lesions/masses based on the risk factors in that particular patient. In this case report, we present a simple oral mass in a patient who had an oral fibroma and lipomas in other areas.

Abstract
According to the latest epidemiological data the occurrence of oral squamous cell carcinoma has increased recently in the last 4 decades. In spite of the great emphasis and effort in the field of prevention, novel medication therapy, our knowledge has to be enlarged in the development of this serious disease. Recent epidemiological studies and animal experiments have shown that there is a relationship between type-2 diabetes and oral squamous cell carcinoma. Our goal was to screen human saliva samples for possible biomarkers for oral malignancies in diabetic patients.

It is well-known that there is an interplay between hemostasis, thrombosis and cancer. Functional DNA polymorphisms in genes encoding factors related to thrombosis have been associated with increased risk for oral squamous cell carcinoma (OSCC). The present study investigated the possible combinatory effect of 10 such polymorphisms as primary risk predictors for OSCC in a European population. Two groups including 160 patients with OSCC and 168 healthy controls of Greek and German origin were studied. The patient and control groups were comparable regarding ethnicity, age and gender. For all studied individuals, 10 genotypes of functional polymorphisms were investigated: 5,10-methylene tetrahydrofolate reductase (MTHFR) C677T, coagulation factor V (F5) Leiden, coagulation factor II (F2, also known as prothrombin) G20210A, coagulation factor XII (F12) C46T, coagulation factor XIII A1 subunit (F13A1) Val34Leu, serpine1 (SERPINE1, also known as plasminogen activator inhibitor-1) 4G/5G, protein Z (PROZ) -A13G, angiotensin I-converting enzyme (ACE) I/D, angiotensinogen (AGT) Met325Thr, and carboxypeptidase B2 (CPB2, also known as thrombin-activatable fibrinolysis inhibitor) C1040T. Multivariate logistic regression models were used in order to evaluate the relation and contribution of homozygous and heterozygous variant polymorphisms upon overall, early and advanced stages of OSCC. Five out of the studied polymorphisms, influencing the expression of SERPINE1 and ACE genes, as well as the activity of CPB2, F12 and F13 proteins, were recognized as significant predictive factors for OSCC. The 'mode of inheritance' regression model, in particular, revealed the low expression I allele of ACE to be a primary predictor in overall, early and advanced stages of oral cancer. Comparing the present findings with previous knowledge, possible interactions of these factors and their relation to the risk for OSCC development are discussed.
