Resumo: Introducción: Las lesiones en la mucosa bucal son frecuentes en la población de adultos mayores, lo cual repercute en la aparición del cáncer bucal. Objetivo: Caracterizar las lesiones en las mucosas bucales y su relación con los factores de riesgo presentes en una población geriátrica, del Policlínico Dr. Tomás Romay, Habana Vieja. Material y Métodos: Estudio descriptivo en los 137 adultos mayores de ambos sexos del consultorio 2 del Policlínico Dr. Tomás Romay, Habana Vieja, entre 2015-2016. A todos se les solicitó su consentimiento de participación, se les realizó un interrogatorio y el examen bucal. Se tuvieron en cuenta las variables edad, sexo, tipo de lesión y la localización de las mismas; además de los factores de riesgo de lesiones bucales. Resultados: El 62,8 por ciento fueron mujeres, 24,8 por ciento tenía entre 60-69 años y 45,3 por ciento presentó lesiones, con mayor frecuencia las del paladar duro (62,9 por ciento) y la mucosa del carrillo (20,9 por ciento). Se identificaron siete tipos de lesiones bucales, con una primacía de la estomatitis subprótesis (62,9 por ciento). La ingestión de alimentos calientes o muy condimentados alcanzó el mayor porcentaje (85,5 por ciento) y le siguió las prótesis desajustadas (75,8 por ciento). Conclusiones: En la población geriátrica estudiada, las mujeres son las más afectadas y los que presentan 70 años y más. Son más frecuentes las lesiones en el paladar duro y la estomatitis subprótesis, observándose mayor riesgo en los pacientes con prótesis dentales desajustadas, en los que ingieren alimentos calientes y muy condimentados, y en los fumadores(AU)

Introduction: Lesions of the buccal mucosa are frequent in older adults, which has an effect on the appearance of buccal cancer. Objective: To characterize lesions in the buccal mucosa, and their relation to risk factors in a geriatric population in Dr. Tomás Romay Polyclinic, Old Havana. Material and methods: A descriptive study was conducted using data from 137 older adults of both sexes treated in doctor´s office No. 2 of Dr. Tomás Romay Polyclinic in Old Havana, from 2015-2016. A consent for participation was asked to all of them, a questionnaire was applied, and buccal examinations were done. Variables such as age, sex, kind of lesion, and location of the lesions were taken into account, as well as the risk factors for buccal lesions. Results: The 62,8 percent of the participants in the study were women, 24,8 percent aged 60-69 years, and 45,3 percent presented lesions which were more frequently observed in the hard palate (62,9 percent) and the mucosa of the cheek (20,9 percent). Seven kinds of buccal lesions were identified, with a priority of subprosthesis stomatitis (62,9 percent). The ingestion of hot or very spiced food reached the highest percentage (85,5 percent), followed by prosthesis loosen (75,8 percent). Conclusions: In the geriatric population studied, the most affected people are women and those people who are 70 years old or older. The most frequent lesions are the ones that appear in the hard palate and subprosthesis stomatitis, observing a highest risk in those patients with loosening of dental prosthesis, in those people who ingest hot and very spicy food, and in smokers(AU)

Idioma: es.
Resumo: El Quiste Óseo Traumático de la mandíbula es una cavidad intraósea sin revestimiento epitelial, considerado Pseudoquiste. Ha recibido diversas denominaciones debido a su etiología y patogenia inciertas, como Quiste Óseo Traumático, Quiste Óseo Solitario, Quiste Óseo Idiopático, entre otros. Es una lesión asintomática, que a menudo se diagnostica accidentalmente durante el examen radiológico de rutina, como una radiolucencia unilocular con bordes festoneados cuando está localizado entre las raíces dentarias. Presentamos un caso raro de Quiste Óseo Traumático en la sínfisis mandíbular, identificado radiográficamente, en una paciente de 14 años sin historia clara de trauma, diagnosticado y tratado con éxito.

The Traumatic Bone Cyst of the mandible is an intraosseous cavity without an epithelial lining, considered a pseudocyst. It has received various names due to its uncertain etiology and pathogenesis, such as Traumatic Bone Cyst, Solitary Bone Cyst, Idiopathic Bone Cyst, among others. It is an asymptomatic lesion, which is often diagnosed accidentally during routine radiological examination, as a unilocular radiolucency with scalloped edges when located between the dental roots. We present a rare case of Traumatic Bone Cysts in the mandibular symphysis, identified radiologically, in a 14-year-old patient without clear history of trauma, diagnosed and successfully treated .

Resumo: Introducción: Staphylococcus aureus es un microorganismo que posee características particulares de virulencia y resistencia a los antibióticos para uso clínico cuya diseminación es de gran importancia en salud pública. Objetivo: Identificar S. aureus sensibles y resistentes a antimicrobianos, colonizantes en cavidad bucal de niños que concurrieron para un tratamiento a una Clínica Odontológica en Asunción. Materiales y Métodos: En este estudio descriptivo, observacional realizado de agosto a septiembre de 2013, se incluyeron niños de 2 a 15 años de edad. Hisopados de cavidad bucal fueron colectados y cultivados en agar-manitol-sal. Los aislados de S. aureus fueron caracterizados respecto a la susceptibilidad a 11 antibióticos y por métodos moleculares se buscó la presencia del gen mecA y del factor de virulencia pvl. Se empleó un cuestionario sobre datos socio-demográficos y factores de riesgo asociados a infección con S. aureus. Resultados: Se incluyeron 112 niños. Se aisló S. aureus en 37 (33%) hisopados y 35 (94,6%) aislados presentaban resistencia a al menos un antibiótico. Resultaron resistentes a: Penicilina (89%), Cloranfenicol (16,2%), Oxacilina (10,8%), Eritromicina (8%), Clindamicina (8%), Gentamicina (5,4%) y un aislado con resistencia intermedia a Ciprofloxacina (2,7%). Cuatro aislados de S. aureus presentaban resistencia a múltiples drogas, los mismos portaban el gen mecA. No se detectó portación del factor de virulencia PVL. Conclusión: La elevada portación en cavidad oral de S. aureus multiresistentes en niños sin factores de riesgo como hospitalización previa o consumo de antibióticos, implica un alto riesgo para posibles infecciones endógenas, además del potencial de transferencia de determinantes de resistencia entre gérmenes de flora bucal normal .

Título: Frequency of periodontal pathogens and Helicobacter pylori in the mouths and stomachs of obese individuals submitted to bariatric surgery: a cross-sectional study
Fonte: J. appl. oral sci;24(3):229-238tab.
Idioma: en.
Projeto: Minas Gerais Research Foundation; . São Paulo Research Foundation.
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: Propolis is a substance manufactured by Apis mellifera and has been widely used in folk medicine due to its high concentration of bioactive compounds. The purpose of the following study was to characterize and evaluate in vitro the antimicrobial properties of propolis on clinical samples and ATCC strains. The chemical characterization of propolis presents a concentration of total polyphenols of 247 ± 9 mg EAG g-1 MS, flavones and flavonols 75± 4 mg EQ g-1 MS, flavanonones and flavanonols 118 ± 11 EP g-1 MS. HPLC-DAD identified apigenin, galangin, phenethyl ester of caffeic acid and pinocembrin, in addition to 16 compounds by HPLC MS/MS. Chilean propolis is a natural antimicrobial, showing effectiveness in strains ATCC Staphylococcus aureus, Candida albicans, Trichophyton rubrum and clinical samples of Staphylococcus aureus unlike Escherichia coli. These results demonstrate the antimicrobial effectiveness of the synergy of compounds present in propolis against different human pathogens.

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.

Título: Oral Candida spp carriage and periodontal diseases in HIV-infected patients in Ribeirão Preto, Brazil

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.
