Analysis of scientific production in oral pathology: a descriptive study

Objective: This research aimed to make a profile of the researches in an oral pathology post graduate program regarding to annual distribution, research subjects and financial support. Methods: The publications from the Annals Books from the Annual Session of the Brazilian Society of Research in Odontology (SBPqO) were analyzed, since 1984 until 2009. The sample was composed by 116 works, with the greater part (88) done after the doctoral program creation. Results: Seventeen (14.6%) works were made prior to creation of doctorate program, and the major part (n=99 / 85.4%) was done after that. The prevalent research subjects were: oral cancer (31.8%) and odontogenic cysts and tumors (18.2%). CNPq and CAPES were the most remarkable financial support agencies, with 30.8% and 24.8% each one, respectively. Conclusions: The program evaluated here exemplifies the scientific production of post graduation programs in oral pathology, showing its role in execution and publication of scientific works, also following the changes in research that occurred in Brazil in the last decades

Transplante de medula óssea: doença enxerto versus hospedeiro e alterações orais

OBJETIVO: Este estudo objetivou avaliar a prevalência de alterações orais e sua associação com a doença enxerto versus hospedeiro (DEVH) em pacientes submetidos a transplante de medula óssea (TMO). METODOLOGIA: A amostra consistiu de 51 pacientes. Por meio de questionário, foram coletados dados sobre idade, sexo, doença, tipo e tempo de transplante, origem das células e ocorrência da DEVH. Foram realizados exames clínicos extra e intraoral por profissionais especializados. RESULTADOS: DEVH sistêmica foi observada em 32,5% dos pacientes transplantados alogênicos, todos apresentando manifestações orais. Também houve uma associação estatisticamente significante entre DEVH sistêmica e manifestações orais (P<0,001). CONCLUSÃO: Diante da prevalência de alterações orais relativamente alta associada à DEVH em pacientes submetidos ao TMO, o presente estudo confirma a necessidade de se considerar a odontologia no exame, diagnóstico, tratamento e prognóstico de possíveis complicações após o transplante de medula óssea.PURPOSE: This study aimed to evaluate the prevalence of oral changes and their association with graft versus host disease (GVHD) in patients undergoing bone marrow transplantation (BMT). METHODS: The sample consisted of 51 BMT patients. A questionnaire was used to collect data on age, gender, disease, type and time of transplant, cell origin, and GVHD occurrence. The extraoral and intraoral clinical examinations were performed by specialized professionals. RESULTS: Systemic GVHD was observed in 32.5% of the allogeneic transplant patients, and all of the patients with GVHD had oral manifestations. There was a statistically significant association between systemic GVHD and oral manifestations (P<0.001). CONCLUSION: Given the relatively high prevalence of oral changes associated with GVHD in patients undergoing BMT, this study confirms the need to consider dental aspects in the examination, diagnosis, treatment and prognosis of possible complications after BMT

Intraoral molluscum contagiosum in a young immunocompetent patient

Molluscum contagiosum (MC) is a contagious disease caused by a virus of the poxvirus family. In children, the disease commonly manifests as a variable number of discrete umbilicated papules on the face and trunk. In healthy and immunosuppressed adults, the disease appears on or near the genital organs and is often sexually transmitted. MC involving the intraoral mucosa has been documented but is rare. We report a case of MC involving the oral mucosa exclusively and discuss the main clinical, histopathologic, and therapeutic characteristics, comparing the findings with cases of this rare oral presentation described in the literatur

PAPEL DE LOS staphylococcus spp. EN LA MUCOSITIS ORAL: REVISIÓN DE LA LITERATURA

Se estima que m&aacute;s de 500 especies bacterianas habitan el medio ambiente oral de seres humanos. Entre ellas, son conocidas m&aacute;s de 400 especies, adem&aacute;s de una gran diversidad de microorganismos que han sido descubiertos gracias a innovaciones en las t&eacute;cnicas de biolog&iacute;a molecular. Con relaci&oacute;n a los staphylococcus spp., su presencia en el medio ambiente oral de individuos saludables, local o sist&eacute;micamente comprometidos es bastante controversia, lo que remite a la necesidad de estudios cuidadosos con intenci&oacute;n de aclarar el papel de esas bacterias en la ecolog&iacute;a de ese microambiente, as&iacute; como en la etiolog&iacute;a de enfermedades orales y sist&eacute;micas. Ese estudio propuso reunir los conocimientos actuales sobre la presencia de staphylococcus en el medio ambiente oral y sus implicaciones en el desarrollo de mucositis oral, denominada en ese caso de "mucositis estafiloc&oacute;cica oral", una condici&oacute;n cl&iacute;nica que afecta m&aacute;s com&uacute;nmente pacientes mayores, sist&eacute;micamente debilitados o inmunol&oacute;gicamente comprometidos.ABSTRACTIt is estimated that more than 500 bacterial species inhabit the human oral environment. Among them, more than 400 species are known, and also a huge diversity of microorganisms that have been discovered because of the innovations in molecular biology techniques. Talking about staphylococcus spp., its presence in oral environment of health individuals and local or systemic wounded ones is at least controversial, what guides to the necessity of accurate studies in order to clarify this bacteria profile in this microenvironment ecology, as well as in oral and systemic disease etiology. This study aimed to gather the current knowledge concerning the staphylococcal presence in oral environment and its implications in oral mucositis development, in this case called "oral staphylococcal mucositis", a clinical condition that affects more commonly ancient patients, systemic weakened or immunologically wounded
