Abstract
BACKGROUND The purpose of this study was to investigate the pathohistological status of mucous lining infected with Helicobacte pylori as the possible cause of chronic laryngitis and laryngeal carcinoma. MATERIALS AND METHODS The prospective examination included 51 patients suffering from planocellular laryngeal cancer and 26 examinees suffering from chronic laryngitis. The examinees and the control group were subjected to esophagogastroduodenoscopy which described the local status of the esophagus and stomach. Two biopsy samplings are taken from the stomach antrum and corpus. One part of the biopsies was colored using the histological technique used in the pathohistological detection of H. pylori, while the other part was incorporated in paraffin cubes where the H. Pylori gene expression was determined using the deparaffinization and PCR method DNA isolation. RESULTS In the group of examinees suffering from laryngeal tumor, there were a higher number of patients suffering also from chronic gastritis (32/51) than in the other group, suffering from chronic laryngitis (9/26). In the chronic laryngitis group, there were more examinees with acute gastritis (12/26) than in the examined group (11/51). The difference is statistically significant (p = 0.0457). CONCLUSION Chronic gastritis and H. pylori infection are risk factors for laryngeal carcinoma formation; therefore, acute gastritis with helicobacter pylori infection must be immediately treated to not let infection to become chronic.

Abstract
BACKGROUND Recurrent aphthous stomatitis (RAS) is the most common form of oral ulcerative disease, whose cause is still unknown. Researchers have found the association of many factors with the occurrence of RAS, and proposed oral bacterial infection could be a cause for this disease. METHODS To investigate whether the occurrence of RAS is associated with oral bacterial infection, we performed high throughput sequencing analysis of bacterial samples collected from the normal oral mucosa and aphthous ulcers of 24 patients. RESULTS Firmicutes, Proteobacteria and Bacteriodetes were the most abundant phyla in the microbiomes analysed. The alpha diversities of the oral mucosa and aphthous ulcer microbiomes were similar, suggesting a similar richness and diversity. The NMDS analysis showed the oral mucosa and aphthous ulcer microbiomes are significantly different. This suggestion is further supported by Anosim, MRPP, and Adonis analyses. More detailed comparison of the two groups of microbiomes suggested that the occurrence of RAS is significantly associated with the increase of Escherichia coli and Alloprevotella, as well as the decrease of Streptococcus. CONCLUSIONS Considering E. coli is a very common intestinal bacterium, we propose that E. coli colonization could be a cause for RAS, and controlling E. coli colonization could help curing RAS.

Abstract
Recurrent aphthous stomatitis (RAS) is the most common acute oral ulcerative condition in North America. RAS is divided into a mild, common form, simple aphthosis, and a severe, less common form, complex aphthosis. Aphthosis is a reactive condition. The lesions of RAS can represent the mucosal manifestation of a variety of conditions. These include conditions with oral and genital aphthae such as ulcus vulvae acutum, reactive nonsexually related acute genital ulcers, and Behçet disease. The mouth is the beginning of the gastrointestinal (GI) tract, and the lesions of RAS can be a manifestation of GI diseases such as gluten-sensitive enteropathy, ulcerative colitis, and Crohn disease. Complex aphthosis may also have correctable causes. The clinician should seek these in a careful evaluation. Successful management of both simple and complex aphthosis depends on accurate diagnosis, proper classification, recognition of provocative factors, and the identification of associated diseases. The outlook for patients with both simple and complex aphthosis is positive.

Abstract
OBJECTIVE The aim of this study was to detect the prevalence of oral H.pylori among adults and to investigate the correlation between H.pylori infection and common oral diseases. STUDY DESIGN A cross-sectional study was performed among adults Chinese who took their annual oral healthy examination at The First Affiliated Hospital, Zhejiang University School of Medicine, China. RESULTS The study included 1050 subjects in total and oral H.pylori infection occurred in 60.29% of the subjects. The prevalence rates of oral H.pylori in patients with periodontal diseases (63.42%) and caries (66.91%) were significantly increased than those without oral diseases (54.07%), respectively (P < 0.05), while the difference between subjects with recurrent aphthous stomatitis and controls was not significant. In addition, the differences of positive rates of H.pylori with or without history of gastric ulcer were statistically significant (69.47% vs 58.26%, P<0.05). Presenting with periodontal diseases (OR 1.473;95% CI 1.021 to 2.124), caries (OR 1.717; 1.127 to 2.618), and having history of gastric ulcer (OR 1.631; 1.164 to 2.285) increased the risk of H.pylori infection. CONCLUSIONS Oral H.pylori infection is common in adult Chinese, which is significantly associated with oral diseases including periodontal diseases and caries.

Abstract
BACKGROUND Specific pathogenic bacteria have been implicated in recurrent aphthous stomatitis (RAS), a chronic inflammatory condition characterised by ulcerations in the oral mucosa. However, the aetiology behind this condition still remains unclear. OBJECTIVE The buccal microbiota of patients with RAS was compared to that of control subjects to investigate its potential role for this condition. DESIGN Buccal swabs were obtained from non-ulcerative areas of 60 patients, of whom 42 patients had lesions at the time of sampling, and 60 healthy age- and gender-matched controls. Bacterial DNA was extracted and analysed by Terminal-Restriction Fragment Length Polymorphism, using enzymatic digestion of the polymerase chain reaction-amplified 16S rRNA gene, yielding a series of peaks, each representing a bacterial taxon. RESULTS Two peaks, 60 and 489, were more prevalent in patients with RAS than controls. Conversely, peaks 58 and 490 were less common in patients than controls. When the patients were divided into subgroups, we found that the observed differences in peak-pattern were related to the presence of lesions during sampling. CONCLUSIONS The microbiota of the non-inflamed buccal mucosa differed between patients and controls. The differences were most pronounced in patients who presented with lesions during sampling, suggesting that a disturbance in the normal buccal microbiota triggers the presence of lesions or that presence of lesions alters the microbiota.

Abstract
Helicobacter pylori (H. pylori) has been found in the oral cavity and stomach, and its infection is one of the most frequent worldwide. We reviewed the literature and conducted a Topic Highlight, which identified studies reporting an association between H. pylori-infection in the oral cavity and H. pylori-positive stomach bacterium. This work was designed to determine whether H. pylori is the etiologic agent in periodontal disease, recurrent aphthous stomatitis (RAS), squamous cell carcinoma, burning and halitosis. Record selection focused on the highest quality studies and meta-analyses. We selected 48 articles reporting on the association between saliva and plaque and H. pylori-infection. In order to assess periodontal disease data, we included 12 clinical trials and 1 meta-analysis. We evaluated 13 published articles that addressed the potential association with RAS, and 6 with squamous cell carcinoma. Fourteen publications focused on our questions on burning and halitosis. There is a close relation between H. pylori infection in the oral cavity and the stomach. The mouth is the first extra-gastric reservoir. Regarding the role of H. pylori in the etiology of squamous cell carcinoma, no evidence is still available.

Abstract
The aim of this study was to investigate the 1-year period prevalence of oral aphthous ulcers (OAUs) and their association with oral health-related quality of life (OHQOL) in patients with Behçet's disease (BD) and in the general population. In this cross-sectional study, 675 patients with Behçet's disease (BD group) and 1,097 males and females in the Japanese general population (control group) completed both questionnaires on their OAU status during the prior year and the General Oral Health Assessment Index (GOHAI). In the BD group, 84% of patients reported experiencing an OAU during the previous year, and the mean number of OAUs/year was 13. In the control group, 31% of individuals experienced an OAU during the previous year, and the mean number of OAUs/year was one. Multivariate analysis indicated that both BD patients (OR, 6.2; 95% CI, 4.8–8.0) and controls (OR, 2.6; 95% CI, 2.0–3.5) who had OAUs at least twice per year were more likely to have GOHAI scores below the norm than were controls who had fewer than two OAUs per year. The association between HLA-B∗51 and OAUs remains unknown. The presence of OAUs has a negative effect on the OHQOL of patients with BD.

Abstract
Background and aims. Helicobacter pylori is a microaerophilic gram-negative spiral organism. It is recognized as the etiologic factor for peptic ulcers, gastric adenocarcinoma and gastric lymphoma. Recently, it has been isolated from dental plaque and the dorsum of the tongue. This study was designed to assess the association between H. pylori and oral lesions such as ulcerative/inflammatory lesions, squamous cell carcinoma (SCC) and primary lymphoma.
Materials and methods. A total of 228 biopsies diagnosed as oral ulcerative/inflammatory lesions, oral squamous cell carcinoma (OSCC) and oral primary lymphoma were selected from the archives of the Pathology Department. Thirty-two samples that were diagnosed as being without any pathological changes were selected as the control group. All the paraffin blocks were cut for hematoxylin and eosin staining to confirm the diagnoses and then the samples were prepared for immunohistochemistry staining. Data were collected and analyzed.
Results. Chi-squared test showed significant differences between the frequency of H. pylori positivity in normal tissue and the lesions were examined (P=0.000). In addition, there was a statistically significant difference between the lesions examined (P=0.042). Chi-squared test showed significant differences between H. pylori positivity and different tissue types except inside the muscle layer as follows: in epithelium and in lamina propria (P=0.000), inside the blood vessels (P=0.003), inside the salivary gland duct (P=0.036), and muscle layer (P=0.122).
Conclusion. There might be a relation between the presence of H. pylori and oral lesions. Therefore, early detection and eradication of H. pylori in high-risk patients are suggested.

Abstract
UNLABELLED Recurrent aphthous stomatitis (RAS) is a disease characterized by the periodic appearance of aphthous lesions on the oral mucosa, of which etiology and physiopathology are not well explained. Recent studies with direct immunofluorescence show controversial results. Some reveal that the basic disorder is associated with humoral immunity, while others point to changes in cellular immunity. Atypical forms of aphthous stomatitis may have its differential diagnosis carried out with vesicobullous diseases, such as pemphigus vulgaris. AIM Check the presence of immunocomplexes in the mucosa of patients with aphthous stomatitis and the usefulness of the differential diagnosis method with bullous skin diseases. MATERIALS AND METHODS 23 patients with aphthous stomatitis were prospectively included in the study. There were all submitted to mucosa biopsy under local anesthesia for the removal of two fragments. One of these was sent to histology and, the other to direct immunofluorescence. RESULTS The 23 samples from the histology exam revealed an ulcerated inflammatory process. The samples referred to immunofluorescence resulted negative and only one showed the presence of complement in the basal membrane. CONCLUSION Based on our results, we conclude that the patients with RAS do not show deposits of immunocomplexes in their oral cavity mucosa and immunofluorescence is useful in the differential diagnosis between this disease and bullous skin diseases.

Abstract
A estomatite aftóide recorrente é doença caracterizada por aparecimento periódico de aftas na mucosa oral, cuja etiologia e fisiopatologia não estão bem explicadas. Estudos recentes com imunofluorescência direta mostram resultados controversos. Alguns revelam que o distúrbio básico está relacionado à imunidade humoral, enquanto outros apontam alterações da imunidade celular. Formas atípicas de estomatite aftóide podem fazer diagnóstico diferencial com doenças vésico-bolhosas como pênfigo vulgar. OBJETIVO: Verificar a presença de imunecomplexos na mucosa de pacientes com estomatite aftóide e utilidade do método no diagnóstico diferencial com dermatopatias bolhosas. CASUÍSTICA E MÉTODO: 23 pacientes portadores de estomatite aftóide, de modo prospectivo, foram incluídos no estudo. Todos foram submetidos à biópsia de mucosa sob anestesia local para retirada de dois fragmentos. Um deles foi enviado para exame histológico e, outro, para ser realizada a imunofluorescência direta. RESULTADOS: As 23 amostras no exame histológico revelaram processo inflamatório inespecífico ulcerado. As amostras enviadas para imunofluorescência resultaram negativas e apenas uma revelou presença de complemento em membrana basal. CONCLUSÃO: Baseado em nossos resultados, concluímos que pacientes portadores de EAR não apresentam depósitos de imunecomplexos na mucosa da cavidade bucal e a imunofluorescência é útil no diagnóstico diferencial entre a doença e dermatopatias bolhosas.

Abstract
BACKGROUND AND AIMS Recurrent aphthous ulcers (RAU) in the oral cavity are painful, causing substantial morbidity in the US and elsewhere in the world. Despite this, there is a lack of population-based studies representative of the US national adult population to describe the epidemiology, and estimate the true disease burden and association with independent risk factors. Although several studies have investigated the role of various factors in RAU etiology, the epidemiology and etiology of RAU remain unclear. This study aims to establish the prevalence and describe the epidemiology of RAU in adults. METHODS Data from the Third National Health and Nutrition Examination Survey (NHANES III) were analyzed in SUDAAN using multivariable logistic regression, modeling RAU occurrences. RESULTS Overall, for all Americans regardless of age, prevalence of RAU was 1030 per 100,000 people (95% CI 830-1220). The prevalence of RAU among adults was 850 per 100,000 (95% CI 630-1070). The lower vestibule was the most commonly involved site. Multivariable analyses suggested that adjusted odds of RAU were greatest for those 17-29 years of age (adjusted OR 2.7; 95% CI 1.4-5.5), for men (adjusted OR 1.7; 95% CI 0.9-2.8), and for those with low serum insulin levels (OR 2.0; 95% CI 0.9-4.4). Never smokers had greater risk of RAU (OR 9.2, 95% CI 2.8-30.1) compared with those who smoked more than 10 cigarettes per day. CONCLUSION This study establishes the prevalence of RAU among adults in the US and demonstrates that whereas cigarette smoking is associated with lesser odds, low insulin levels might be independently associated with greater odds of RAU.

Abstract
AIM The present study aimed to evaluate if the oral cavity of chronic periodontitis patients can harbor Helicobacter pylori after systemic eradication therapy. MATERIALS AND METHODS Samples of 30 patients (15 with gingivitis and 15 with chronic periodontitis) positive for H. pylori in the stomach were evaluated. Samples were collected 3 months after triple systemic antibiotic therapy from saliva, microbiota from the dorsum of the tongue, supra- and sub-gingival plaque as well as gastric biopsies. DNA of each sample was extracted by the boiling method and used as a template in polymerase chain reaction with the primers JW22/23. RESULTS Eighteen patients (60%) harboured H. pylori in their mouths. Five patients (16.6%) were positive in saliva, two (6.6%) on the dorsum of the tongue, nine (30%) in supra-gingival plaque, 14 (46.6%) in sub-gingival plaque and three (10%) in the stomach. There was no statistically significant difference between study groups. CONCLUSION Eradication of H. pylori after therapy was more effective for the stomach than for the mouth (p<0.001). Mouths of patients with gingivitis or with chronic periodontitis, who are positive for H. pylori in their stomachs, may be considered as reservoirs of these bacteria.

Abstract
BACKGROUND The microorganism Helicobacter pylori has been closely linked to chronic gastritis, peptic ulcer, gastric cancer, and mucosa-associated lymphoid tissue (MALT) lymphoma. Despite the current treatment regimens that lead to successful management of H. pylori-positive chronic gastritis, the reinfection rate is high. It has been suggested that one of the possible mechanisms of reinfection is the recolonization from dental plaque. The purpose of this study was to determine whether dental plaque, poor oral hygiene, and periodontal disease were risk factors for H. pylori infection. METHODS Among the 134 patients, 65 patients who had a positive H. pylori serology or positive rapid urease test or histologic evidence for the presence of H. pylori in antral biopsy specimens were categorized as cases. The remaining 69 patients who were negative for H. pylori serology, the rapid urease test, and histology were controls. RESULTS It was found that the association of periodontal disease and poor oral hygiene with H. pylori infection was not significant. There was a higher prevalence of H. pylori in the dental plaque of patients with gastric H. pylori infection than in controls, but both groups had a surprisingly high positive urease test for H. pylori in plaque (89% and 71%, respectively). CONCLUSIONS H. pylori in dental plaque is seldom eliminated by H. pylori-eradication therapy, and this may act as a source for future reinfection. Hence, eradication of H. pylori from the dental plaque should be made an important part of comprehensive management of H. pylori-associated gastric diseases.

Abstract
Recurrent aphthous stomatitis (RAS; aphthae; canker sores) is a common condition which is characterized by multiple recurrent small, round or ovoid ulcers with circumscribed margins, erythematous haloes, and yellow or grey floors typically presenting first in childhood or adolescence. RAS occurs worldwide although it appears most common in the developed world. The aetiology of RAS is not entirely clear. Despite many studies trying to identify a causal microorganism, RAS does not appear to be infectious. A genetic predisposition is present, as shown by strong associations with genotypes of IL-1beta; IL-6 in RAS patients, and a positive family history in about one-third of patients with RAS. Haematinic deficiency is found in up to 20% of patients. Cessation of smoking may precipitate or exacerbate RAS in some cases. Ulcers similar to RAS may be seen in human immunodeficiency virus disease and some other immune defects, and drugs, especially non-steroidal anti-inflammatory drugs and nicorandil may produce lesions clinically similar to RAS. Topical corticosteroids can often control RAS. However, the treatment of RAS remains unsatisfactory, as most therapies only reduce the severity of the ulceration and do not stop recurrence.

Abstract
Despite recent advances in understanding the immunopathogenesis of oral lichen planus (LP), the initial triggers of lesion formation and the essential pathogenic pathways are unknown. It is therefore not surprising that the clinical management of oral LP poses considerable difficulties to the dermatologist and the oral physician. A consensus meeting was held in France in March 2003 to discuss the most controversial aspects of oral LP. Part 1 of the meeting report focuses on (1) the relationship between oral LP and viral infection with special emphasis on hepatitis C virus (HCV), and (2) oral LP pathogenesis, in particular the immune mechanisms resulting in lymphocyte infiltration and keratinocyte apoptosis. Part 2 focuses on patient management and therapeutic approaches and includes discussion on malignant transformation of oral LP.

Abstract
BACKGROUND Considering not only the fact that recurrent aphthous stomatitis (RAS) and stomach ulcers are immunologically mediated ulcers associated with Helicobacter pylori, but also the recent evidence that anaemia can be associated with both diseases, and the discovery of H. pylori in the oral mucosa led us to hypothesize that this bacteria may be related to RAS pathogenesis. METHODS Thirty-six consecutive subjects affected by minor and major forms of RAS and 48 healthy volunteers were included in the present study. The nested polymerase chain reaction (PCR) technique was used to detect the presence of H. pylori in the oral lesion, the normal contralateral mucosa of patients affected by RAS and the oral mucosa of control subjects. The chi2- and Fisher's tests were used for statistical analysis. RESULTS No association between RAS lesions and H. pylori was observed. However, 14 out of 36 (38.9%) of the patients with RAS were found to show the presence of H. pylori DNA in the lesion and/or contralateral mucosa. Sixteen out of 48 (33.3%) of the patients without RAS (control subjects) were positive (P > 0.05). CONCLUSION The present study does not give support to the assumption that H. pylori could be involved in RAS development.

Abstract
OBJECTIVES We investigated the relationship between Helicobacter pylori infection and abnormal periodontal conditions. METHODS Data from the first phase of the third National Health and Nutrition Examination Survey were used. A total of 4504 participants aged 20 to 59 years who completed a periodontal examination and tested positive for H. pylori antibodies were examined. RESULTS Periodontal pockets with a depth of 5 mm or more were associated with increased odds of H. pylori seropositivity (odds ratio [OR] = 1.47; 95% confidence interval [CI] = 1.12, 1.94) after adjustment for sociodemographic factors. This association is comparable to the independent effects of poverty on H. pylori (OR = 1.54; 95% CI = 1.10, 2.16). CONCLUSIONS Poor periodontal health, characterized by advanced periodontal pockets, may be associated with H. pylori infection in adults, independent of poverty status.

Abstract
Lichen planus is a relatively common disorder of the stratified squamous epithelia. Most dental and medical practitioners see patients with lichen planus, but not all are recognized as having the disease. Patients with lichen planus may have concomitant involvement of the disease in multiple sites. Oral lichen planus lesions usually have a distinctive clinical morphology and characteristic distribution, but oral lichen planus may also present a confusing array of patterns and forms, and other disorders may clinically mimic oral lichen planus. The etiopathogenesis of lichen planus appears to be complex, with interactions between genetic, environmental, and lifestyle factors. Much has now been clarified about the etiopathogenic mechanisms involved and interesting new associations, such as with liver disease, have emerged. The management of lichen planus is still not totally satisfactory in all cases and there is as yet no definitive treatment that results in long term remission, but there have been advances in the control of the condition. Amongst the many treatments available, high potency topical corticosteroids remain the most reliably effective, though topical cyclosporine, topical tacrolimus, or systemic corticosteroids may be indicated in patients whose condition is unresponsive to topical corticosteroids.

Abstract
OBJECTIVE The purpose of this study was to exam the oral mucosa and peripheral blood cells of patients with recurrent aph-thous ulceration (RAU) for the presence of the following human herpesviruses: herpes simplex viruses 1 and 2, varicella zoster virus, Epstein-Barr virus, cytomegalovirus, human herpesvirus-6, and human herpesvirus-7. STUDY DESIGN Fifty-eight subjects with RAU and 10 control subjects were recruited at an academic referral center and enrolled in this prospective, nonrandomized, case-controlled study. Each of the subjects with RAU was seen during an acute episode, and swab specimens from lesional (RAU-acute/lesion) and clinically normal (RAU-acute/normal) oral mucosa were obtained. Each of 2 subjects with RAU was evaluated during more than one acute episode. Three subjects with RAU were seen between active episodes, and swab specimens were taken from clinically normal (RAU-convalescent) oral mucosa. Swab specimens from clinically normal (control/normal) oral mucosa were obtained from the control subjects. Peripheral blood specimens were obtained from subjects with RAU and control subjects at the time the swab specimens were performed. Through use of polymerase chain reaction, all swab and peripheral blood specimens were examined for the presence of human herpesvirus DNA. Statistical significance was determined by means of chi(2) analysis. RESULTS Herpes simplex virus and human herpesvirus-6 were found in a higher percentage of mucosal specimens from the control subjects (herpes simplex virus, 4/10; human herpesvirus-6, 5/9) than from the subjects with RAU (RAU-acute/lesion: 3/45 herpes simplex virus, 13/53 human herpesvirus-6; RAU-acute/normal: 7/48 herpes simplex virus, 9/53 human herpesvirus-6). No difference was demonstrated between RAU-acute/lesion, RAU-acute/normal, and RAU-convalescent mucosal specimens for any of the human herpesviruses. Different human herpesviruses were identified from individual subjects with RAU during subsequent episodes of disease. Epstein-Barr virus (6/35), human herpesvirus-6 (3/40), and human herpesvirus-7 (7/43) were detected in the peripheral blood mononuclear cells during acute RAU but not in RAU-convalescent or control peripheral blood mononuclear cells. CONCLUSIONS The detection of human herpesvirus DNA from the oral mucosa and peripheral blood mononuclear cells of patients with RAU appears to represent normal viral shedding rather than a direct causal mechanism in this disorder.

Abstract
A causative role for Helicobacter pylori (H. pylori) in the pathogenesis of oral mucosal ulcerations has been suggested previously. We have adopted the polymerase chain reaction (PCR) as a rapid and sensitive means to detect H. pylori in swabs of recurrent oral aphthous ulcers and in samples of other oral sites. Of the oral aphthous ulcer samples, 32 (71.8%) were found to be positive, while the saliva and plaque samples (most of them taken from the patients with aphthous ulcers) were consistently negative for H. pylori DNA, as detected by the PCR assay. Only two of the swab samples from the tongue (collected at the time of concurrent, H. pylori-positive oral aphthous ulcers) were found to be positive. The data suggest that H. pylori may be associated frequently with recurrent oral aphthous ulcers, and are consistent with previous studies indicating that saliva and plaque are not likely sources of contamination with this microorganism. There was no apparent correlation with HIV status (infection with human immunodeficiency virus). The possible pathogenic significance of Helicobacter pylori in oral ulcerations is discussed.

Abstract
Oral ulcers are common in AIDS patients, with a wide spectrum of underlying causes, including different viruses. In the present study, the presence of cytomegalovirus (CMV), Epstein-Barr virus (EBV) and human herpesvirus-8 (HHV-8) DNA was analysed in 21 biopsies from oral ulcers of 17 male homosexual AIDS patients. The methods used were in situ hybridization (ISH) and the polymerase chain reaction (PCR) with subsequent non-radioactive Southern blot hybridization to confirm the specificity of PCR products. With ISH, 4 biopsies were CMV DNA-positive and 11 contained EBV-DNA. Using PCR, an additional 4 CMV- and 7 EBV-positive samples were detected, and HHV-8 DNA was present in three oral ulcers. Six of the patients (35%) had oral ulcers co-infected by two or three viruses. The overall figures for patients with the detectable EBV-, CMV-, and HHV-8 DNA were 82% (14/17), 35% (6/17) and 18% (3/17), respectively. This is the first study to show the frequent presence of EBV-DNA in oral ulcers of AIDS patients. Because ISH-positivity signifies active virus replication, these results implicate an etiological role of EBV in AIDS-associated oral ulcers. The causal role of HHV-8 has to be considered as well, because this virus was detected in three such ulcers, which were not associated with Kaposi's sarcoma. To conclude, three common members of the herpesvirus family (CMV, EBV, HHV-8) were detected in all but three ulcers in AIDS patients, warranting the inclusion of these viral analyses in the diagnosis of ulcerative lesions of the oral mucosa in all immunosuppressed individuals.

Abstract
Human papillomaviruses (HPV) are involved in the etiology of both benign and malignant epithelial lesions. The occurrence of HPV types 16 and 18 in gynecological squamous cell carcinomas is also well known. Of the herpesviruses, Epstein-Barr virus (EBV) is associated with, for example, undifferentiated nasopharyngeal carcinoma, endemic Burkitt's lymphoma and immunoblastic lymphoma, and human herpesvirus 8 (HHV-8) with Kaposi's sarcoma. As little is known about the etiological factors of salivary gland tumours, the presence of HPV, EBV, HHV-8 and human cytomegalovirus (CMV) in these tumours were examined. Fresh tissue samples obtained from 19 consecutive pleomorphic adenomas and 19 malignant salivary gland tumours were analyzed with polymerase chain reaction. Two samples showed EBV DNA positivity, a lymphoma of the parotid gland and a pleomorphic adenoma arising in the nasal cavity. HPV, HHV-8 and CMV DNA were not detected in any of the tumour samples. The results indicate that HPV, HHV-8 and CMV do not seem to have any role in the etiology of salivary gland neoplasms.

Abstract
In this study we used the polymerase chain reaction (PCR), slot blot and Southern blot hybridization, direct sequencing and in situ hybridization (ISH) to show the possible presence of EBV-DNA in pre-ulcerative oral aphthous lesions of patients with recurrent aphthous ulcers (RAU) or Behçet's disease (BD). For this purpose, formalin-fixed biopsy specimens were obtained from 13 pre-ulcerative oral aphthous lesions of nine RAU and four BD patients. Five specimens of normal oral mucosa (NOM) from five normal control subjects and 10 specimens of oral erosive or ulcerative lesions from 10 patients with erosive lichen planus (ELP) were also included. EBV-DNA was detected by PCR in 5 of the 13 (38.5%) pre-ulcerative oral aphthous lesions, two from RAU patients and three from BD patients. However, no EBV-DNA was demonstrated in five NOM specimens from normal control subjects and in 10 specimens of oral lesions from ELP patients. EBV-DNA was also demonstrated in patients' peripheral blood lymphocytes and/or plasma, suggesting that the lymphocytes may be the reservoir of latent EBV infection and there is EBV shedding in the plasma. EBV-DNA was detected by ISH in only one PCR-positive case; the reaction product was found to deposit on the nuclei of some of the epithelial cells and lymphocytes. By immunohistochemistry, expression of Epstein-Barr nuclear antigen and EBV/C3d receptors was also noted in some of the epithelial cells and lymphocytes in this ISH-positive case. Therefore, we suggest that the epithelial cells of pre-ulcerative oral aphthous lesions may be infected by EBV through EBV-infected lymphocytes; also, the cytotoxic T lymphocyte-induced lysis of the EBV-infected epithelial cells, but not the virus-induced cytolysis, may be the main mechanism causing oral ulcer formation. Our data provide preliminary evidence for an association of EBV with pre-ulcerative oral aphthous lesions in RAU and BD patients.

Abstract
In order to study a possible role of Helicobacter pylori infection in chronic laryngitis, we performed endoscopic and histological assessments in addition to a urease test for the bacterium in 35 patients with chronic hoarseness. Six of the patients investigated (17.1%) revealed a positive urease test of the laryngeal biopsy (four male and two female patients). These H. pylori-positive patients were treated with omeprazole and an antibiotic regimen using clarithromycin and metronidazole. This led to an eradication of the H. pylori and resolution of clinical signs and symptoms. These findings show a possible role of H. pylori infection in the etiology of chronic laryngitis in certain patients and can be important for clinical diagnosis and treatment.

Abstract
Nested PCR was used for the detection of Helicobacter pylori DNA in specimens collected from seven different topographic sites in the oral cavity. Out of 161 patients, only 21 (13.04%) were positive. There was no correlation between H. pylori status and patient diagnosis and age. No preferential site for bacterial colonization was found in the oral cavity, nor was an association established between a bacterial presence and ulcerated versus non-ulcerated lesions. The results indicate that the oral mucosa does not appear to represent a preferred site of colonization for H. pylori. Furthermore, the evidence presented in this paper suggests that H. pylori is not pathogenic in the oral cavity, nor is it associated with common oral pathologic processes.

Abstract
In the present study, the involvement of human herpesvirus 6 (HHV-6), human cytomegalovirus (HCMV) and varicella zoster virus (VZV) in the aetiology of recurrent aphthous stomatitis (RAS) was investigated using the polymerase chain reaction (PCR). Biopsies from 21 RAS patients were analysed, and 20 oral lichen planus (OLP) and 13 normal biopsies were tested as controls. HHV-6-DNA was detected in six of the RAS samples whereas VZV-DNA and HCMV-DNA were not detected in any RAS samples. In the OLP samples, four biopsies were positive for HHV-6-DNA and two were positive for HCMV-DNA. One sample from this group was positive for both HHV-6-DNA and HCMV-DNA. VZV-DNA was not found in any RAS or OLP biopsies. No viral DNA was present in any normal control biopsies. These results do not support an aetiological role for HCMV and VZV in RAS, although the possible involvement of HHV-6 cannot be excluded.

OBJECTIVES To compare the frequency of serum anti-Helicobacter pylori IgG antibodies in patients with recurrent aphthous stomatitis with patients with other oral ulcerative and nonulcerative disorders. STUDY DESIGN Prospective study of serum IgG antibodies to H. pylori in 75 patients with recurrent aphthous ulcers, 15 patients with other oral ulcerative disorders, 41 patients with other oral mucosal lesions, 27 patients with oral dysaesthesia, and 25 healthy control patients without oral lesions. RESULTS The frequency of anti-H, pylori seropositivity was not significantly greater in patients with recurrent aphthous stomatitis (30.6%) compared with patients with other ulcerated oral mucosal lesions (33.0%) and controls (24%). CONCLUSIONS Helicobacter pylori does not appear to be of etiologic significance in the development of recurrent aphthous stomatitis.

Abstract
We have measured serum levels of IgG subclasses and total IgG, IgA and IgM in a group of 34 recurrent aphthous stomatitis (RAS) patients. At the time of blood collection, 23 of the 34 patients had active oral lesions. The remaining 11 patients were at an inactive stage. All measurement were performed in the Beckmann 360 Array Protein System. Serum levels of IgG2 subclass were significantly lower (P < 0.05) in the whole group of patients (34) when compared to the control group. This relationship was still significant (P < 0.05) when only the 11 patients without active oral lesions were considered but disappeared in patients at an active stage. We conclude that low serum levels of IgG2 may play a role in the pathogenesis of RAS, just as in other recurrent infectious diseases, and that serum levels of this immunoglobulin subclass, as well as total IgA, may undergo transient changes, depending on the different periods of activity and quiescence of the disease.

Abstract
In a preliminary study on anti-human cytomegalovirus (HCMV) antibody (Ab) by ELISA, the serum anti-HCMV/IgG Ab concentrations in 22 patients with recurrent aphthous ulcers (RAU) in the remission stage were found to be significantly higher than in 22 control subjects (121 +/- 42 vs 100 +/- 27, P < 0.05) and in 39 patients with RAU in the active stage (121 +/- 42 vs 88 +/- 45, P < 0.01). Therefore, the potential of HCMV as an etiologic agent in RAU was proposed and studies using the polymerase chain reaction (PCR) and in situ hybridization (ISH) have been performed to investigate the possible presence of HCMV DNA in pre-ulcerative oral aphthous lesions in patients with RAU or Behçet's disease (BD) of the mucocutaneous type. For this purpose, formalin-fixed biopsy specimens were obtained from 13 pre-ulcerative oral aphthous lesions, 2 samples of normal oral mucosa and 1 ileal mucosal lesion from 9 RAU patients and 4 BD patients. Five specimens of normal oral mucosa from 5 normal control subjects and 12 specimens of oral erosive or ulcerative lesions from 12 patients with erosive lichen planus (ELP) were also included. By PCR, HCMV DNA was detected in 5 of the 13 (38.5%) pre-ulcerative oral aphthous lesions, 3 from RAU patients and 2 from BD patients. The ileal mucosa specimen was also HCMV DNA-positive, whereas HCMV DNA was not demonstrated in any of the 7 specimens of normal oral mucosa from RAU patients and normal control subjects; 12 specimens of oral lesions from ELP patients were similarly negative. ISH did not detect HCMV DNA in any of the biopsy specimens from RAU patients and control subjects. Our findings suggest that HCMV may be an etiologic agent in some cases of RAU and BD.
