Resumo: ABSTRACT Objectives This cross-sectional study compared the frequency of oral periodontopathogens and H. pylori in the mouths and stomachs of obese individuals with or without periodontitis submitted to bariatric surgery. Material and Methods One hundred and fifty-four men and women aged 18-65 were conveniently distributed into four groups. Two groups were composed of individuals who underwent bariatric surgery with (BP) (n=40) and without (BNP) (n=39) periodontitis and two obese control groups with (CP) (n=35) and without (CNP) (n=40) periodontitis. The oral pathogens Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, Parvimonas micra, Treponema denticola, Tannerella forsythia, Campylobacter rectus, and Helicobacter pylori were detected by a polymerase chain reaction technique using saliva, tongue and stomach biopsy samples. Results Statistical analysis demonstrated that periodontopathogens were highly frequent in the mouth (up to 91.4%). In the bariatric surgically treated group, orally, P. gingivalis, T. denticola and T. forsythia were more frequent in periodontitis, while C. rectus was more frequent in non-periodontitis subjects. Stomach biopsies also revealed the high frequency of five oral species in both candidates for bariatric surgery (91.6%) and the bariatric (83.3%) groups. H. pylori was frequently detected in the mouth (50.0%) and stomach (83.3%). In the stomach, oral species and H. pylori appeared in lower frequency in the bariatric group. Conclusions Obese individuals showed high frequencies of periodontopathogens and H. pylori in their mouths and stomachs. Bariatric surgery showed an inverse microbial effect on oral and stomach environments by revealing higher oral and lower stomach bacterial frequencies.

Resumo: ABSTRACT Purpose The aim of this study was to identify β-lactamase-producing oral anaerobic bacteria and screen them for the presence of cfxA and BlaTEM genes that are responsible for β-lactamase production and resistance to β-lactam antibiotics. Material and Methods Periodontal pocket debris samples were collected from 48 patients with chronic periodontitis and anaerobically cultured on blood agar plates with and without β-lactam antibiotics. Presumptive β-lactamase-producing isolates were evaluated for definite β-lactamase production using the nitrocefin slide method and identified using the API Rapid 32A system. Antimicrobial susceptibility was performed using disc diffusion and microbroth dilution tests as described by CLSI Methods. Isolates were screened for the presence of the β-lactamase-TEM (BlaTEM) and β-lactamase-cfxA genes using Polymerase Chain Reaction (PCR). Amplified PCR products were sequenced and the cfxA gene was characterized using Genbank databases. Results Seventy five percent of patients carried two species of β-lactamase-producing anaerobic bacteria that comprised 9.4% of the total number of cultivable bacteria. Fifty one percent of β-lactamase-producing strains mainly Prevotella, Porphyromonas, and Bacteroides carried the cfxA gene, whereas none of them carried blaTEM. Further characterization of the cfxA gene showed that 76.7% of these strains carried the cfxA2 gene, 14% carried cfxA3, and 9.3% carried cfxA6. The cfxA6 gene was present in three Prevotella spp. and in one Porphyromonas spp. Strains containing cfxA genes (56%) were resistant to the β-lactam antibiotics. Conclusion This study indicates that there is a high prevalence of the cfxA gene in β-lactamase-producing anaerobic oral bacteria, which may lead to drug resistance and treatment failure.

Resumo: Abstract The two-point discrimination (TPD) test is one of the most commonly used neurosensory tests to assess mechanoperception in the clinical settings. While there have been numerous studies of functional sensibility of the hand using TPD test, there have been relatively not enough reports on TPD in the orofacial region. Objective The aims of the present study were to determine the normal values of TPD in the six trigeminal sites (the forehead, cheek, mentum, upper lip, lower lip, and the tongue tip) and to investigate the effect of the site, sex, and test modality on the TPD perception. Material and Methods Forty healthy volunteers consisting of age-matched men (20) and women (20) with a mean age of 27.1 years were recruited. One examiner performed the TPD test using a simple hand-operated device, i.e., by drawing compass with a blunt or sharp-pointed tip. The static TPD with a blunt-pointed tip (STPDB), moving TPD with a blunt-pointed tip (MTPDB), and static TPD with a sharp-pointed tip (STPDS) were measured. The predictors were the site, sex, and test modality, and the outcome variable was the TPD value. Three-way ANOVA was used for statistics. Results The analysis showed a significant effect of the site, sex and test modality on the TPD values. Significant differences between the test sites were observed with the descending order from the forehead and cheek>mentum>upper lip and lower lip>tongue tip and index finger. Women showed lower TPD values than those of men. The STPDS measurements were consistently lower than those of the STPDB and MTPDB. Conclusions The normal values of TPD in this study suggest that the cheek and forehead were less sensitive than other regions evaluated and women were more sensitive than men. The STPDS was the most sensitive test modality.

Idioma: en.
Projeto: National Counsel of Technological and Scientific Development.
Resumo: ABSTRACT The majority of HIV-infected patients develop Candida spp-associated clinical oral lesions. Studies have shown that asymptomatic oral colonization of Candida spp may lead to oral lesions or become a source of disseminated infections. The aim of this study was to verify the effects of periodontal conditions on Candida spp prevalence and Candida spp carriage in the oral cavity of HIV-infected patients compared to non-infected patients. Twenty-five patients not infected with HIV and 48 HIV-infected patients were classified according to periodontal conditions as being periodontal healthy or with periodontal disease. Candida spp carriage and classification were performed in oral rinse samples. Viral load and CD4+ T lymphocyte (CD4+L) counts were performed in blood samples from HIV-infected patients. No differences in Candida spp prevalence related to HIV status or periodontal condition were detected. However, Candida spp carriage was increased in periodontally affected HIV-infected patients when compared to periodontally healthy HIV-infected patients (p= 0.04). Periodontally healthy HIV-infected patients presented Candida spp carriage in similar levels as healthy or periodontally affected non-HIV-infected patients. Candida spp carriage was correlated with CD4+L counting in HIV-infected patients. We concluded that periodontal disease is associated with increased Candida spp carriage in HIV-infected patients and may be a predisposing factor to clinical manifestations of candidiasis.

Título: Carcinoma escamocelular bucal diagnosticado precozmente / Oral squamocellular carcinoma with early diagnosis
Fonte: Rev. cuba. estomatol;47(3):347-354, jul.-sep. 2010.
Idioma: es.
Resumo: El carcinoma escamocelular es la neoplasia maligna más común en la cavidad bucal. Los sitios anatómicos más frecuentemente afectados son el labio inferior, los bordes laterales de lengua y el suelo de la boca. Su etiología es multifactorial, aunque está íntimamente relacionada con factores ambientales como el tabaquismo y el alcoholismo. El cuadro clínico se caracteriza generalmente por la presencia de placas blancas, placas eritematosas, placas entre eritematosas y blancas, úlceras de bordes levantados y masas exofíticas. El tratamiento consiste en la extirpación quirúrgica, la radioterapia, quimioterapia o ambos tratamientos. Este artículo presenta un caso de carcinoma escamocelular bucal en un paciente del sexo masculino, de 70 años de edad. En el mismo se describen los hallazgos clínicos, histopatológicos y el tratamiento correspondiente del caso. El diagnóstico precoz y correcto posibilitó la cura en este caso(AU)

The squamocellular carcinoma is a malignant neoplasm commonest in the buccal cavity. The more frequently involved anatomical sites are the lower lip, the tongue's lateral edges and the mouth floor. Its etiology is multifactor although it is closely related to smoking and alcoholism. Clinical picture is generally characterized by the presence of different types of white, erythematous, between erythematous and white plaques, ulcers with raised edges and exophytic masses. Treatment includes surgical removal, radiotherapy, chemotherapy or both. In present paper the case of a man aged 70 presenting with buccal squamous carcinoma describing the clinical, and the histopathologic findings and its corresponding treatment. The early and appropriate diagnosis allowed the cure of this case(AU)

Título: The importance of early diagnosis of large lipomas in the maxillofacial region / Importancia del diagnóstico precoz de los lipomas de células grandes en la región maxilofacial
Fonte: Rev. cuba. estomatol;48(1):77-83, ene.-mar. 2011.
Idioma: es.
Resumo: Lipoma is a benign tumor composed of proliferation of mature fat cells interspersed by fibrous connective tissue, blood vessels and muscles, delimited by a thin capsule. Although it represents a mesenchymal neoplasm most common human body, are rare occurrences in the oral cavity. Presents clinical and histopathological variables that do not alter their prognosis. The pathogenesis is still uncertain, although some authors consider heredity and endocrine disorders as possible causes. Occurs with greater prevalence in obese people, although their metabolism is completely independent of the normal body lipid metabolism. The clinical diagnosis of oral lipoma is the view of a nodular mass, soft, asymptomatic, flat surface, without ulceration and limited growth. The continuing growth of the lesion may cause difficulty in chewing, speech, dental adaptation and change in facial aesthetics of the patient, requiring surgical excision of the lesion. The final diagnosis is by histopathological examination. Aims to present a literature review and clinical cases of a retrospective study of 61 cases of lipomas diagnosed in pathological service between 1978 and 2009, among the 10 573 reports during that same period. It emphasizes the special cases of large lipomas of the maxillofacial region, and the importance of early diagnosis of these lesions. A dental surgeon should be able to diagnose lipomas in an early stage in the maxillofacial area avoiding a massive growth of these lesions(AU)

El lipoma es un tumor benigno compuesto por la proliferación de células adiposas maduras entremezcladas con el tejido conectivo fibroso, los vasos sanguíneos y/o músculos, delimitado por una fina cápsula. Aunque representa un neoplasma del mesénquima muy común del cuerpo humano, tiene raras ocurrencias en la cavidad bucal. Presenta variables clínicas e histopatológicas que no alteran su pronóstico. La patogénesis sigue siendo incierta aunque algunos autores consideran que los trastornos hereditarios y endocrinos son causas posibles. Ocurre con una mayor prevalencia en las personas obesas, aunque su metabolismo es totalmente independiente del metabolismo normal de los lípidos corporales. El diagnóstico clínico del lipoma bucal está relacionado con una masa nodular, blanda, asintomática, de superficie plana, sin ulceración y de crecimiento limitado. El continuo crecimiento de la lesión pudiera crear dificultad al masticar, al hablar, en la adaptación dental y cambio en la estética facial del paciente requiriendo la escisión de la lesión. Presentar una revisión de la literatura y de los casos clínicos de un estudio retrospectivo de 61 casos de lipomas diagnosticados en el servicio de patología entre 1978 y 2009 entre los 10 573 informes hechos durante ese mismo período. Se enfatizan los casos especiales de lipomas grandes de la región maxilofacial y la importancia del diagnóstico temprano de estas lesiones. Un cirujano dental debe ser capaz de diagnosticar los lipomas en una etapa temprana en el área maxilofacial para evitar un crecimiento masivo de estas lesiones(AU)
