Intra-Oral Spitz Naevus: A Case Report

The Spitz nevus, also known as benign juvenile melanoma or a nevus of epitheloid and spindle cells, was first described by Sophie Spitz in 1948 and is most common in children and adolescents. They can present in three different ways: solitary nodular, multiple grouped, and multiple disseminated. The great majority of lesions are solitary, nodular, and are present in children and adolescents (57%–70%), with a slight preference for the female gender. The regions where they are most frequently found are the lower extremities, the head and neck, and the trunk. A Spitz nevus is usually pink, brown, or black in color. After an initial period of growth, the majority of Spitz nevi tend to stabilize their growth, reaching, in 95% of patients, a final size smaller than 6 mm

Saliva: Métodos Atuais para Coleta e Obtenção da Amostra

The methods for saliva collection consist ways through which can measure as many biological parameters of the components of the saliva as modifications of the volume of the flow to salivar. A great variety of methods for collection of this oral fluid exists, since the simplest, as for example a simple spitting on the part of the proper individual, the method of the draining, suction opened, closed suction, swab, among others until the use of sophisticated devices more for collection as the method salivette, eyespears and the Ultrafiltration Probe. It constitutes a not invasive procedure, of easy attainment and comes more being each used time in the antigen detention as citomegalovírus, virus of simple herpes and antibodies where we can cite the virus of the imunodeficiência humana(HIV), hepatites types, b, c and helicobacter pylori. Giving us an idea of an individual’s health, and the potential oral fluid use detecting amphetamine drugs, opiates and cocaine. The objetive of this article is show innumerable alternatives to saliva collects, as well as comparing one technique to another one guiding the professional for the choice of the collection technique that better to agree to it.Os métodos para coleta de saliva constituem-se maneiras através das quais podemos mensurar tanto parâmetros biológicos dos componentes da saliva como modificações do volume do fluxo salivar. Existe uma grande variedade de métodos para coleta deste fluido oral, desde os mais simples, como por exemplo uma simples expectoração por parte do próprio indivíduo, o método da drenagem, sucção aberta, sucção fechada, do esfregaço entre outros até a utilização de dispositivos mais sofisticados para coleta como o método salivette, eyespears e o Ultrafiltration Probe . Constitui um procedimento não invasivo, de fácil obtenção e vem sendo cada vez mais utilizado na detecção de antígenos como o citomegalovírus, vírus do herpes simples e anticorpos onde podemos citar o vírus da imunodeficiência humana (HIV), hepatites tipos A,B,C e o helicobacter pylori. Podendo desta forma também nos dar uma idéia da qualidade de saúde da pessoa. Além do potencial uso do fluido oral na detecção de drogas como anfetaminas, opióides e cocaína. O objetivo do presente trabalho é mostrar as inúmeras alternativas para a coleta de saliva, bem como comparar uma técnica a outra, orientando o profissional para a escolha da técnica de coleta que melhor lhe convie

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
