- Burning mouth syndrome (BMS) is a chronic orofacial pain disorder that is defined by a burning sensation in the oral mucosa. The aim of this study was to investigate the underlying factors, clinical characteristics and self-reported oral and general health factors associated with BMS.Fifty-six women with BMS (mean age: 67.7) and their age-matched controls were included in the study. A general questionnaire, an OHRQL index and BMS-specific questionnaires were used. Each subject underwent an oral examination.The mean severity of the BMS symptoms (VAS, 0-100) was 66.2 (SD 19.7). Overall, 45% of the patients reported taste disturbances. More of the patients than the controls rated their general health, oral health and life situation as 'less satisfactory'. The patients also reported more frequently on-going medications, diseases/disorders, xerostomia, allergy and skin diseases. Except for more bruxofacets among the patients, there were no significant differences regarding signs of parafunction. In a multiple logistic regression analysis, xerostomia and skin diseases showed the strongest prediction for BMS and no significant effect was found for medication, allergy or bruxofacets.Skin diseases and xerostomia but not parafunction were strongly associated with BMS. Our findings provide the basis for additional studies to elucidate the causal factors of BMS.

- Objective The aim of the study was to examine mucosal saliva and unstimulated (UWS) and stimulated (SWS) whole saliva secretion rates and associated factors, in 56 female patients diagnosed with BMS and age-matched control women. Material and MethodsResultsMucosal saliva was assessed using the Periotron((R)) method and blood flow using laser Doppler flowmetry. Diseases, drug usage and xerostomia were registered using questionnaires. The patients with BMS displayed less lingual and whole saliva, and more hyposalivation, xerostomia diseases/disorders and drug usage, compared to the controls. Only a low SWS and xerostomia differed after adjusting for drugs and systemic diseases. Regression analyses suggested an importance of saliva affecting drugs for saliva on the tongue and for SWS, and the total number of drugs used for UWS. Lingual saliva and UWS were also associated with systemic diseases in the patients. Xerostomia was significantly associated with drug use and whole saliva for all subjects but not in separate analyses of the groups. ConclusionLess saliva in patients with BMS could be related to more systemic diseases and medication and not to the syndrome per se. Xerostomia in the patients was not related to any of these factors.

- Local anesthetics inhibit edema and improve circulation in experimental burns. We evaluated the effect of topical local anesthetics on human skin burns in volunteers using computerized color analysis that allowed repeated noninvasive quantitative measurements. A standardized partial-thickness burn (1 cm2) was induced in one forearm of 10 healthy volunteers and in the opposite forearm a week later. The burned areas were treated with lidocaine/prilocaine cream (EMLA; Astra, Sweden) or a placebo cream for 1 h. The experimental skin area was photographed before and 1, 2, 4, and 12 h postburn. Digitized images were evaluated using normalized red-green-blue and Hue-Saturation-Intensity. Differences in erythema between skin treated with EMLA and placebo were not significant during the first 4 h postburn. However, 12 h postburn, a pronounced decrease in the degree of erythema was observed in EMLA-treated skin compared with placebo-treated skin. We conclude that topical local anesthetics administered for 1 h postburn significantly reduces the duration of erythema after a mild thermal injury, which suggests a potential use in clinical practice in the treatment of minor skin burns.

- Oral lichen planus (OLP) is generally regarded as a premalignant condition. The objective of the present study was to assess the number of oral malignant tumours in a retrospective analysis of 1028 patients (mean age=55 years; range=18-86; female, n=667; men, n=351) who between 1978 to end of 1993 were diagnosed with OLP at the Faculty of Odontology, Göteborg University, Sweden. Patients with malignant tumours were identified through the Swedish Cancer Registry at the National Board of Health and Welfare, which annually reports the incidence of malignant neoplasms in the Swedish population. The incidence of oral squamous cancer (OSCC), other malignant tumours and survival in the study group was compared to the Swedish population. The total time with OLP in the study group amounted to 7009 person years, with a mean follow up of 6.8 years (SD=4.9). The observed incidence of OSCC was higher than the expected incidence in the study group. The difference was statistically significant (P<0.001). No statistically significant difference was found for any other malignant tumours than OSCC. Also, no statistically significant difference could be identified in survival between study group and the population. The results from the present study gives further support to the concept of a small but increased risk for development of squamous cell carcinoma in patients with OLP.

- In order to analyse the clonality of T cells in the inflammatory infiltrate of oral lichen planus (OLP), mucosal biopsies were obtained from seven patients with manifest disease. The biopsies were stained with MoAbs directed against 11 different T cell receptor (TCR) V-gene families, anti-CD4, anti-CD8 and IL-2 receptor (IL-2R). For comparison, the frequencies of the different TCR V-families were determined in biopsies from five patients with oral candidosis as well as in peripheral blood from three patients with OLP and from six healthy blood donors (HBD). The occurrence of the investigated TCR V-families varied between 0% and 7% in venous blood obtained from both HBD and OLP patients. T lymphocytes expressing the TCR V beta 3 and V alpha 2 in OLP biopsies were, however, detected in frequencies ranging between 18% and 40% of the total fraction of lymphocytes, a consistent finding for all the OLP infiltrates studied. The other nine TCR V-families examined appeared in low frequencies both in biopsies and in peripheral blood. V alpha 2+ and V beta 3+ cells were often localized adjacent to the basal membrane. In contrast, T cells in Candida-induced lesions did not express a biased TCR distribution, and most V-families studied appeared in frequencies of 0-6%. Thus, T lymphocytes in OLP lesions express a substantially higher frequency of TCR V alpha 2 and V beta 3 than expected from the distribution in blood. The clonal expansion of T cells observed in OLP suggests that a superantigen is involved in the pathogenesis of the disease. Whether this superantigen is of exogenous or endogenous origin needs to be investigated.

- We analysed and compared MUC7 O-glycosylation and inflammatory biomarkers in saliva from female patients with burning mouth syndrome (BMS) and gender/age-matched controls. Oligosaccharides from salivary MUC7 from BMS and controls were released. Inflammatory mediators were measured by multiplex proximity extension assay. Presence of sialyl-Lewis(x) (Si-Le(x)) epitope on MUC7 was confirmed using Western blot. MUC7 O-glycans and measured inflammatory biomarkers were found to be similar between BMS and controls. However, oligosaccharides sialyl-Lewis(x) (Si-Le(x)) was found to be reduced in samples from BMS patients. Positive correlation (combined patients and controls) was found between levels of C-C motif chemokine 19 (CCL-19) and the amount of core-2 oligosaccharides on MUC7 as well as fractalkine (CX3CL1) and level of sialylation. Patients with BMS were shown to represent a heterogeneous group in terms of inflammatory biomarkers. This indicates that BMS patients could be further stratified on the basis of low-level inflammation. The results furthermore indicate that reduced sialylation of MUC7, particularly Si-Le(x), may be an important feature in patients with BMS. However, the functional aspects and potential involvement in immune regulation of Si-Le(x) remains unclear. Our data suggests a chemokine driven alteration of MUC7 glycosylation.

- Several therapeutic agents have been investigated for the treatment of oral lichen planus (OLP). Among these are corticosteroids, retinoids, cyclosporine, and phototherapy, in addition to other treatment modalities. A systematic review of clinical trials showed that particularly topical corticosteroids are often effective in the management of symptomatic OLP lichen planus. Systemic corticosteroids should be only considered for severe widespread OLP and for lichen planus involving other mucocutaneous sites. Because of the ongoing controversy in the literature about the possible premalignant character of OLP, periodic follow-up is recommended. There is a spectrum of oral lichen planus-like ("lichenoid") lesions that may confuse the differential diagnosis. These include lichenoid contact lesions, lichenoid drug reactions and lichenoid lesions of graft-versus-host disease. In regard to the approach to oral lichenoid contact lesions the value of patch testing remains controversial. Confirmation of the diagnosis of an oral lichenoid drug reaction may be difficult, since empiric withdrawal of the suspected drug and/or its substitution by an alternative agent may be complicated. Oral lichenoid lesions of graft-versus-host disease (OLL-GVHD) are recognized to have an association with malignancy. Local therapy for these lesions rests in topical agents, predominantly corticosteroids.

- Background. Giant papillae tongue disorder (GRID) is a newly discovered, long-lasting clinical disorder that may develop in organ-transplanted pediatric recipients. The key feature of this disorder is the unique tongue lesion, which comprises swollen fungiform papillae. The aim of this study was to characterize the immunohistopathology of this novel inflammatory condition. Methods. Six organ transplanted children with GRID were included in the study. Routine histopathology and immunohistochemical stainings for CD3, CD4, CD8, CD25, FOXP3, CD20, CD138, CD68, CD1a, CD15, CD23, and mast cell tryptase were performed. Results. Immunohistochemical analyses of the oral lesions revealed a subepithelial infiltrate that was primarily composed of CD3- and CD4-positive T cells, CD20-expressing B cells, macrophages, and CD138-positive plasma cells. The CD20-positive cells did not display the typical B cell morphology, having in general a more dendritic cell-like appearance. The CD138-expressing plasma cells were distinctly localized as a dense infiltrate beneath the accumulation of T cells and B cells. Increased numbers of CD1a-expressing Langerhans cells were detected both in the epithelium and connective tissue. Because no granulomas were observed and only single lesional eosinophils were detected, GPTD does not resemble a granulomatous or eosinophilic condition. Conclusions. We describe for the first time the immunopathological characteristics of a novel inflammatory disorder of the oral cavity, which may develop after solid organ transplantation in children.
