Abstract
OBJECTIVES Human papillomavirus (HPV) in oral carcinoma (OSCC) and potentially malignant disorders (OPMD) is controversial. The primary aim was to calculate pooled risk estimates for the association of HPV with OSCC and OPMD when compared with healthy oral mucosa as controls. We also examined the effects of sampling techniques on HPV detection rates. METHODS Systematic review was performed using PubMed (January 1966-September 2010) and EMBASE (January 1990-September 2010). Eligible studies included randomized controlled, cohort and cross-sectional studies. Pooled data were analysed by calculating odds ratios, using a random effects model. Risk of bias was based on characteristics of study group, appropriateness of the control group and prospective design. RESULTS Of the 1121 publications identified, 39 cross-sectional studies met the inclusion criteria. Collectively, 1885 cases and 2248 controls of OSCC and 956 cases and 675 controls of OPMD were available for analysis. Significant association was found between pooled HPV-DNA detection and OSCC (OR = 3.98; 95% CI: 2.62-6.02) and even for HPV16 only (OR = 3.86; 95% CI: 2.16-6.86). HPV was also associated with OPMD (OR = 3.87; 95% CI: 2.87-5.21). In a subgroup analysis of OPMD, HPV was also associated with oral leukoplakia (OR = 4.03; 95% CI: 2.34-6.92), oral lichen planus (OR = 5.12; 95% CI: 2.40-10.93), and epithelial dysplasia (OR = 5.10; 95% CI: 2.03-12.80). CONCLUSIONS The results suggest a potentially important causal association between HPV and OSCC and OPMD.

Abstract
Four oral mucosal infections were identified as Global Oral Health Priorities: (a) HIV and associated viral, bacterial, and fungal infections; (b) tuberculosis; (c) NOMA; and (d) sexually transmitted diseases. Huge global inequalities exist in all four. HIV-associated infections constitute the major challenge. Oral manifestations of AIDS can be specifically diagnostic, indicating a significant role for dentists within health teams. The World Workshops in Oral Health & Disease in AIDS have identified a research program, elements of which are being implemented. Data on oral mucosal involvement in tuberculosis, syphilis, and gonorrhea are incomplete in developed countries and virtually non-existent in low- and middle-income countries, indicating the need for further epidemiological studies. Oral manifestations of tuberculosis and sexually transmitted diseases are largely associated with general health, so action programs should be integrated with agencies treating the systemic diseases. NOMA is very much in the oral health domain. It is a preventable disease associated with malnutrition and unidentified bacterial factors. Prevalence is probably grossly overestimated at present; but nevertheless it constitutes a challenge to the profession, especially in the NOMA belt. Current treatment is surgical, but plans for its eradication should be achievable. The global oral health community, especially the IADR, has a major role to play.

Abstract
Intranasal inoculation of mice with monoclonal IgA against the alpha-crystallin (acr1) antigen can diminish the tuberculous infection in the lungs. As this effect has been observed only over a short-term, we investigated if it could be extended by inoculation of IFNgamma 3 days before infection, and further co-inoculations with IgA, at 2 h before and 2 and 7 days after aerosol infection with Mycobacterium tuberculosis H37Rv. This treatment reduced the lung infection at 4 weeks more than either IgA or IFNgamma alone (i.e. 17-fold, from 4.2 x 10(7) to 2.5 x 10(6) CFU, P = 0.006), accompanied also by lower granulomatous infiltration of the lungs. IFNgamma added prior to infection of mouse peritoneal macrophages with IgA-opsonized bacilli resulted in a synergistic increase of nitric oxide and TNFalpha production and a 2-3 fold decrease in bacterial counts. Our improved results suggest, that combined treatment with IFNgamma and IgA could be developed towards prophylactic treatment of AIDS patients, or as an adjunct to chemotherapy.

Abstract
SETTING Dendritic cells (DC) could regulate between the protective and pathogenic immune responses following tuberculous infection. In this paper we investigated if their early infection in the lungs represents a plausible alternative to cross-priming with mycobacterial antigens acquired from infected macrophages. OBJECTIVE To determine the extent and time course of infection of lung DCs following intranasal inoculation of BALB/c mice with green fluorescent protein (GFP) tagged Bacillus Calmette-Guerin (BCG). RESULTS A fraction of GFP-BCG infected lung cells were classified as monocytic DCs with the CD11c+IA+33D1+CD8a- phenotype. These cells represented 5-18% of the total GFP+ cells, the bulk of which were macrophages. The infected DCs could be separated by cell size into two fractions with similar cell surface staining properties during the 2-72 h period after infection. An unexpected difference was observed for the time course of infection between DCs and macrophages: DC infection peaked at 48 h followed by decline at 72 h, while the proportion of infected macrophages remained steady during the same period. CONCLUSION The presented results are direct evidence that monocytic DCs are recruited to the lungs and take up live bacilli within 48 h of intranasal infection with GFP-BCG. This finding is pertinent for the regulation of pulmonary and systemic immune responses and possibly for the dissemination of mycobacterial infection by DCs.

Abstract
OBJECTIVES To determine the prevalence of legionellae in dental unit waterlines (DUWL) in general dental practices in London and rural Northern Ireland and whether the organism occurs at a high enough frequency and magnitude in DUWL to represent a threat to dentists' health. MATERIALS AND METHOD Two hundred and sixty six (166 London, 100 Northern Ireland) randomly selected dental surgeries were recruited. Standardised 250 ml water samples were taken from the DUWL and 1 litre samples from the surgery cold water tap to measure the prevalence of legionellae. The dentists provided a blood sample for legionella serology. RESULTS The prevalence of legionellae was very low (0.37%). Legionellae were not isolated from DUWL or surgery basin taps in Northern Ireland. Legionella spp were isolated from the DUWL and surgery basin of one practice in London and from the cold water supply of a further three practices. The prevalence of Legionella pneumophila antibodies was less than that seen in a comparable group of London blood donors. CONCLUSION The risk to dentists' health from potential exposure to legionellae in this cohort of dentists was very low and this was confirmed by the very low seroprevalence and antibody titres to legionella detected in the dentists.

Abstract
The intranasal (i.n.) route of immunisation, has recently been of active interest in endeavours to improve the efficacy of vaccination against a number of respiratory infections. Here, we examined the outcome of tuberculous infection in BALB/c mice. I.n. application of the BCG-Pasteur strain was found to be highly protective against challenge infection with the pathogenic H37Rv strain given after a 4-week interval, reflected by the 100-fold reduction of CFUs in both lungs and spleens. Vaccination with the recombinant PstS-1 antigen and cholera toxin significantly protected against the challenge given 10 days later, but only marginally after 12 weeks. Histological examination showed, that i.n. vaccination abrogated the confluent infiltration of lungs with inflammatory cells, which surrounds the granulomas in H37Rv challenged control mice. In conclusion, the strong protection demonstrated by BCG suggests that the i.n. route of vaccine delivery deserves further attention toward improving vaccination against tuberculosis.

Abstract
BACKGROUND The efficacy by which passive antibodies can reach the lungs could be important for the outcome of immunotherapy of respiratory pulmonary infections. We examined how transmission to a number of mucosal sites is affected by the route of inoculation. METHODS Transmission of newly raised IgA class Mabs against mycobacterial surface antigens to saliva, lung or vaginal lavage, bile and serum of BALB/c mice was compared with existing IgG Mabs. ELISA was used for testing body fluids obtained 1-24 h after intranasal or intravenous inoculation and 1-7 days following back-pack tumour growth of hybridomas. RESULTS Intranasal inoculation resulted in a rapid rise and high levels of both IgA and IgG class Mabs in lung lavage. In contrast, following intravenous Mab injection or back-pack tumour growth of hybridoma cells, effective lung transmission was observed for the IgG1 and IgG2b MAbs, but not for the IgA Mabs. The secretory component was acquired by the transmitted IgA MAbs in the mucosal fluids, but not in the serum. Nevertheless, the time course of mucosal IgA antibody levels was similar to that of the tested IgG Mabs. Furthermore, the relative proportion of transmission to saliva and bile varied between individual Mabs indicating a role of tissue-specific, immunoglobulin class-unrelated mechanisms. CONCLUSIONS Intranasal, rather than parenteral inoculation of mice is required for the efficient delivery of IgA antibodies against respiratory pulmonary pathogens. Interestingly, IgA-secretory component complexing of intranasally applied Mabs did not significantly influence their persistence in the lungs.

Abstract
The objective of this study was to assess the pattern of change in salivary immunoglobulins and antibodies to S. mitis and S. oralis in 23 children following allogeneic bone marrow transplantation and their matched controls. To overcome the difficulty of obtaining a sufficient quantity of whole saliva from very young, sick children saliva was collected in a 5-ml oral rinse of sterile normal saline. It was not possible to measure the volume of whole saliva in each rinse and the concentration of the salivary immunoglobulins and bacterial antibodies were estimated from 1 ml of oral rinse. Despite these shortcomings a pattern of change in the mean concentrations of total salivary IgA, secretory IgA, antibodies to S. mitis and S. oralis and total IgG at specific event- related times during the transplantation period has been demonstrated. There was a significant increase in the concentration of salivary IgG 7 days post-transplantation, followed by significant decreases in total salivary IgA, secretory IgA and antibodies to S. mitis after recovery of the peripheral neutrophil count above 0.5 x 10(9). The concentrations of total IgA and antibodies to S. oralis was significantly greater in the transplant group 119 days post-transplantation.

Abstract
Oral manifestations of gastro-intestinal disease are commonly under-diagnosed. This paper is the third in the series entitled 'Recognizing and Caring for the Medically Compromised Child' and seeks to facilitate the process of diagnosis and management of disorders affecting the gastro-intestinal tract in terms of both oral and gut signs and symptoms. This paper concludes with a section devoted to the recognition of HIV disease in paediatric patients, both orally and generally, and its implications for management within the dental surgery.

METHODS Using an indirect immunoperoxidase technique we assessed the expression of the cytokines interleukin-1 alpha (IL-1 alpha), interleukin-1 beta (IL-1 beta), interleukin-8 (IL-8), transforming growth factor beta (TGF beta) and granulocyte macrophage colony stimulating factor (GM-CSF), of the adhesion molecules intercellular adhesion molecule-1 (ICAM-1), lymphocyte function associated antigen-1 (LFA-1), the activated molecular form of LFA-1 (NKI-L16), CD2, and LFA-3, and of a panel of cellular markers in the minor salivary glands. RESULTS In SS and chronic sialoadenitis (CS), the ductal epithelial cells and acini expressed all the cytokines examined. The percentage of glandular mononuclear cells which stained positive for cytokines did not differ significantly between SS and CS. NKI-L16 was detected on 33.6 (SD 10.1)% and 15.3 (4.3)% of LFA-1 cells in SS and CS, respectively (p < 0.002). CONCLUSION SS and CS did not differ in the pattern of cytokines examined. The characteristic cell clustering seen in the salivary glands in SS may be caused by the upregulation of NKI-L16.

Abstract
There is compelling evidence that six patients of a Florida dentist were infected with HIV at the dental practice. The strain of HIV in the dentist and patients was virtually identical. There is no evidence that either lapses in infection control or deliberate attempts to infect patients were responsible for this cluster of cases. Recent media analyses have emphasised that handpieces should be taken seriously as a potential source of cross infection but no evidence is available to confirm this as the route in the Florida practice. The unusual circumstances leading up to the detection of this cluster suggest that there could be other undetected cases and clusters.
