Maxillary odontogenic myxoma involving the maxillary sinus: case report

The aim of this paper is to report a case of odontogenic myxoma that affected the right maxilla and maxillary sinus. We have also reviewed the literature in regards of the clinical, radiographic, histological and treatment aspects of this pathology. Odontogenic myxomas of the maxillofacial region are benign lesions, without preference for gender, race or location, with extremely varied clinical and radiographic characteristics, thus increasing the number oral and maxillofacial region tumors with which we can make the differential diagnosis.

Mixoma odontogênico maxilar: relato de caso clínico comprometendo seio maxilar

O objetivo deste artigo e relatar um caso de mixoma odontogenico no lado direito da maxila com envolvimento do seio maxilar e fazer uma revisao de literatura envolvendo aspectos clinicos, radiograficos, histologicos e de tratamento desta patologia. O mixoma odontogenico dos maxilares e uma lesao benigna, sem preferencia por sexo, raca ou localizacao, com caracteristicas clinicas e radiograficas extremamente variadas, o que amplia demasiadamente o numero de patologias tumorais do sistema estomatognatico com as quais pode ser feito o diagnostico diferencial.

Chemopreventive Effect of Brazilian Green Propolis on Experimental Dermal Carcinogenesis in Murine Model

El objetivo de este estudio fue evaluar el efecto de la administracion oral de extracto hidroalcoholico del propoleos verde (HEGP) sobre la carcinogenesis dermica en modelo de roedores. Para el ensayo biologico, se utilizaron 36 ratones asignados en 6 grupos (n = 6): CTR (tratado con 100 mg/kg HEGP y sin induccion de tumores), TUM (tratada con agua e induccion de tumores), GP10 (tratado con 10 mg/kg HEGP e induccion de tumores), GP50 (tratado con 50 mg/kg HEGP e induccion de tumores) y GP100 (tratado con 100 mg/kg HEGP e induccion de tumores). La induccion de cancer se llevo a cabo en la region dorsal de los ratones por aplicacion topica de DMBA. Despues de 16 semanas, los ratones fueron sacrificados y sus dorsos fueron sometidos a analisis histologico post-mortem. El numero medio de lesiones desarrolladas en TUM (4,14±0,89) fue significativamente mayor que GP10 (2,05±1,02), GP50 (1,8±1,92) y gp100 (2,5±1,73) (p<0,05). Los tumores formados en grupos tratados con HEGP fueron histologicamente mas diferenciados, pero solo en PV100 las lesiones in situ fueron manifiestas. La infiltracion de las estructuras anatomicas blanco fue menos frecuente en los grupos tratados con HEGP (p<0,05). Nuestros datos sugieren que la administracion oral de HEGP proporciona una inhibicion parcial de la carcinogenesis dermica inducida por DMBA, asi como parecio modular la diferenciacion y potencial infiltrante de los carcinomas en el modelo animal.

RETARDO NO DIAGNÓSTICO DO CÂNCER BUCAL: ENTENDENDO OS FATORES RELACIONADOS

Objective: To discuss the main factors related to delay in the diagnosis of oral cancer and its influence on prognosis. Method: This is a literature review conducted in the databases PubMed, SciELO and BIREME, for the period 2002 to 2012, with the keywords “oral cancer”, “head and neck cancer” and “delay”. We found 141 articles in MEDLINEPubMed, 05 in SciELO and 51 in BIREME. After reading the abstracts, thirty articles were selected for analysis. Results: Several factors related to the tumor, patient, professional and local health system may cause and influence the diagnostic delay. The total period of delay can vary from few days to years, however, the most often cited interval was between 3-4 months and the patient was responsible for most of this delay. Few studies have shown statistically the association between greater delay in diagnosis and more advanced stage of oral cancer. Conclusion: The oral cancer diagnostic delay still lasts long in Brazil and worldwide. From a statistical view, the literature remains controversial about the main factors related to this issue and about its influence on prognosis. DESCRIPTORES: Mouth neoplasms. Delayed diagnosis. Oral Medicine.

Comparative analysis of Brazilian medical and dental ethics codes

Professional ethics codes are norms (federal authority resolutions) prepared by members of the different categories of workers with the goal to guide the ethical conduct of these professionals in relation to patients, colleagues and society. The aim of this study was to carry out a comparative analysis of ethical codes in Dentistry and Medicine. It was observed that differences between these documents were due more to the particularities of each profession than to different focus, facing similar problems. It was concluded that Dentistry and Medicine ethical codes have more points in common than differences, but it would be interesting that Class Advisory Committees, when proposing actualizations and changes to their current co- des, they will look what other health care professions view as deontological norms, with the end to have into account aspects which may be important also for their professional class, in order to extend the codes and facilitate to physicians and dentists ethical decision making in their daily task in benefit to the health of human beings and community.Professional ethics codes are norms (federal authority resolutions) prepared by members of the different categories of workers with the goal to guide the ethical conduct of these professionals in relation to patients, colleagues and society.
