Could mucin 16 and colony-stimulating factor 2-receptor beta possible graft versus host disease biomarkers? Medical hypotheses.

Graft versus host disease (GVHD) occurs after bone marrow transplantation and is one of the most important causes of death worldwide. Reviews demonstrated GVHD patients with involvement of various tissues and organs, such as salivary glands. The diagnosis of acute GVHD has been the biopsies and the histopathologic evaluation of tissue from an involved organ. These procedures are invasive. Saliva proteins as possible biomarker for GVHD could facilitate the management and diagnosis accuracy. For support the proposed hypotheses, in this pilot study we collected whole saliva samples from patients with undergoing allogeneic hematopoietic cell transplantation (HCT) and from healthy subjects. Samples were collected prospectively between pre-transplant, thirty days, one hundred and, two hundred days after transplant. The proteomic profile was analyzed using SDS-PAGE and LCMS-ESI-IT-TOF mass spectrometry. The relevant personal data, past medical history were also recorded. The most relevant proteins found exclusively in GVHD patients were: CSF2RB, Protocadherin (Pcdh) Fat 2 precursor, protein capicua homolog isoform CIC-S, MUC16 and RGPD8_HUMAN RANBP2. This study aims to conduct an initial evaluation of the possible presence of such biomarkers in saliva from GVHD patients, and suggested a potential application of proteomics analysis as a alternative method to diagnose GVHD.

Effects of periodontal treatment on primary sjȫgren's syndrome symptoms.

The aim of this longitudinal prospective study was to evaluate the effects of periodontal treatment on the clinical, microbiological and immunological periodontal parameters, and on the systemic activity (ESSDAI) and subjective (ESSPRI) indexes in patients with primary Sjögren's Syndrome (pSS). Twenty-eight female patients were divided into four groups: pSS patients with or without chronic periodontitis (SCP, SC, respectively), and systemically healthy patients with or without chronic periodontitis (CP, C, respectively). Periodontal clinical examination and immunological and microbiological sample collection were performed at baseline, 30 and 90 days after nonsurgical periodontal treatment (NSPT). Levels of interleukin IL-1ß, IL-8 and IL-10 in saliva and gingival crevicular fluid (GCF) were evaluated by ELISA, as well as the expression of Porphyromonas gingivalis (Pg), Aggregatibacter actinomycetemcomitans, (Aa) Tannerella forsythia (Tf), and Treponema denticola (Td), by qPCR. Systemic activity and pSS symptoms were evaluated by ESSDAI and ESSPRI. NSPT resulted in improved periodontal clinical parameters in both SCP and CP groups (p>0.05). Pg, Aa, and Tf levels decreased after NSPT only in CP patients (p<0.05). Significantly greater levels of IL-10 in GCF were verified in both SCP and CP groups (p<0.05). SCP patients showed increased salivary flow rates and decreased ESSPRI scores after NSPT. In conclusion, NSPT in pSS patients resulted in improved clinical and immunological parameters, with no significant effects on microbiological status. pSS patients also showed increased salivary flow and lower ESSPRI scores after therapy. Therefore, it can be suggested that NSPT may improve the quality of life of pSS patients.

Effects of periodontal treatment on primary sjogren's syndrome symptoms

Abstract The aim of this longitudinal prospective study was to evaluate the effects of periodontal treatment on the clinical, microbiological and immunological periodontal parameters, and on the systemic activity (ESSDAI) and subjective (ESSPRI) indexes in patients with primary Sjögren’s Syndrome (pSS). Twenty-eight female patients were divided into four groups: pSS patients with or without chronic periodontitis (SCP, SC, respectively), and systemically healthy patients with or without chronic periodontitis (CP, C, respectively). Periodontal clinical examination and immunological and microbiological sample collection were performed at baseline, 30 and 90 days after nonsurgical periodontal treatment (NSPT). Levels of interleukin IL-1β, IL-8 and IL-10 in saliva and gingival crevicular fluid (GCF) were evaluated by ELISA, as well as the expression of Porphyromonas gingivalis (Pg), Aggregatibacter actinomycetemcomitans, (Aa) Tannerella forsythia (Tf), and Treponema denticola (Td), by qPCR. Systemic activity and pSS symptoms were evaluated by ESSDAI and ESSPRI. NSPT resulted in improved periodontal clinical parameters in both SCP and CP groups (p>0.05). Pg, Aa, and Tf levels decreased after NSPT only in CP patients (p<0.05). Significantly greater levels of IL-10 in GCF were verified in both SCP and CP groups (p<0.05). SCP patients showed increased salivary flow rates and decreased ESSPRI scores after NSPT. In conclusion, NSPT in pSS patients resulted in improved clinical and immunological parameters, with no significant effects on microbiological status. pSS patients also showed increased salivary flow and lower ESSPRI scores after therapy. Therefore, it can be suggested that NSPT may improve the quality of life of pSS patients.

A Rare Case of Concomitant Maxilla and Mandible Brown Tumours, Papillary Thyroid Carcinoma, Parathyroid Adenoma, and Osteitis Fibrosa Cystica.

Objective. The brown tumour of hyperparathyroidism is a result of a metabolic disorder caused by primary hyperparathyroidism. Report. We described a case of a 37-year-old female patient presenting bimaxillary intraoral lesions and swelling in the neck. Incisional biopsy of the oral lesion was performed and histopathological examination revealed a central giant cell lesion composed by intense haemorrhagic exudate, abundant presence of giant cells, and areas with hemosiderin pigment. The patient also presented high levels of serum calcium and parathyroid hormone, hyperfunctioning parathyroid tissue, bilateral parenchymal nephropathy, and densitometry lower than expected, showing an advanced stage of osteitis fibrosa cystica. Synchronous parathyroid adenoma and papillary thyroid carcinoma were confirmed by imaging exams and histopathologically. Conclusion. The composition of all the clinical, pathological, and imaging findings led to the final diagnosis of brown tumour of hyperparathyroidism. The occurrence of parathyroid adenoma, papillary thyroid carcinoma, and brown tumours of hyperparathyroidism in their late stage (osteitis fibrosa cystica) associated with oral brown tumours involving the mandible and maxilla is extremely rare.

Correlation between gender, temporomandibular joint disc position and clinical findings in patients with temporomandibular disorder / Correlação entre sexo, posição do disco da articulação temporomandibular e os resultados clínicos em pacientes com disfunção temporomandibular

OBJECTIVE: The objective of this study was to assess gender differences in temporomandibular joint disc position using magnetic resonance imaging and to check for symptoms in patients with temporomandibular disorders. MATERIALS AND METHODS: Eighty-seven consecutive patients (70 females and 17 males) were evaluated. Bilateral magnetic resonance imaging was performed to determine the temporomandibular joint disc positions; these were divided into four diagnostic categories: no disc displacement, right disc displacement, left disc displacement and bilateral disc displacement. The clinical data assessed were pain on muscle and temporomandibular joint palpation. The data were analyzed using the Fisher's exact test, chi-square test or analysis of variance. Significance was set at p ≤ .05. RESULTS: The study population had more females (80.5%) than males (19.5%) and the mean age of females (31 ± 11 years) was lower than the mean age of males (41± 12 years). Bilateral disc displacement was significantly most frequent in females. Clinical examination showed more pain on muscle palpation for female than for male patients. CONCLUSION: Women had a higher frequency of temporomandibular joint disc displacement, as well as a larger number of painful points on muscle palpation than men.

RESUMO OBJETIVO: O objetivo deste estudo foi avaliar as diferenças de gênero na posição do disco da articulação temporomandibular usando ressonância magnética para verificar se há sintomas em pacientes com disfunção temporomandibular. MATERIAIS E MÉTODOS: Foram avaliados oitenta e sete pacientes consecutivos (70 mulheres e 17 homens); foi realizada ressonância magnética bilateral para determinar as posições do disco da articulação temporomandibular; estes foram divididos em quatro categorias diagnósticas: nenhum deslocamento de disco, deslocamento de disco a direita, deslocamento de disco a esquerda e deslocamento de disco bilateral. Os dados clínicos avaliados foram: dor a palpação no músculo e na articulação temporomandibular. Os dados foram analisados utilizando o teste exato de Fisher, teste do qui-quadrado ou análise de variância. Significância foi de p ≤ 0,05. RESULTADOS: A população do estudo tinha mais mulheres (80,5%) que homens (19,5%). O deslocamento blateral de disco foi significativamente mais frequente no sexo feminino. O exame clínico mostrou mais dor à palpação muscular para mulheres do que para homens. CONCLUSÃO: As mulheres apresentaram uma maior frequência de deslocamento de disco da articulação temporomandibular, bem como um maior número de pontos dolorosos à palpação muscular do que os homens.

Candida albicans isolation from buccal mucosa of patients with HIV wearing removable dental prostheses.

PURPOSE: The aim of this study was to evaluate the influence of complete or partial removable dental prostheses (RDPs) on the frequency of Candida albicans isolated from the mouth and the presence of oral candidiasis in human immunodeficiency virus-positive (HIV+) patients correlated with CD4 levels. MATERIALS AND METHODS: One hundred ninety-three HIV+ patients were evaluated; 68 had RDPs and 125 did not. CD4 cell count was obtained after blood sampling and performed on the day of clinical examination. The material was collected from the buccal mucosa for isolation of yeasts with a sterile swab and seeded onto Sabouraud dextrose agar with chloramphenicol. C albicans strains were identified by testing germ tubes and chlamydospore formation and biochemical (zymogram, auxanogram) characteristics. The results were subjected to the Fischer exact test and chi-square tests. RESULTS: C albicans were isolated from 45 (66.17%) patients who had RDPs and 48 (38.4%) who did not (P = .0003). The presence of oral candidiasis was observed in 14 patients (7.25%), and 10 of the 14 (71.43%) were RDP users. The absence of candidiasis occurred in 121 (67.59%) nonusers and 58 (32.40%) users of RDPs (P = .0065). The mean CD4 cell count was lower in patients with oral candidiasis regardless of the use of RDPs. CONCLUSION: The use of RDPs was an important factor in the isolation of C albicans among HIV+ patients, and CD4 level seems to play a role in the presence of oral candidiasis.
