Efficacy of Brazilian propolis gel for the management of denture stomatitis: a pilot study

Denture stomatitis presents as a chronic disease in denture‐bearing patients, especially under maxillary prosthesis. Despite the existence of a great number of antifungal agents, treatment failure is observed frequently. Propolis, a natural bee product, possesses well‐documented antifungal and anti‐inflammatory activities. The purpose of this study was to evaluate the clinical efficacy of a new Brazilian propolis gel formulation in patients diagnosed with denture stomatitis. Thirty complete‐denture wearers with denture stomatitis were enrolled in this pilot study. At baseline, clinical evaluation was performed by a single clinician and instructions for denture hygiene were provided. Fifteen patients received Daktarin® (Miconazole gel) and 15 received Brazilian propolis gel. All patients were recommended to apply the product four times a day during one week. Clinical evaluation was repeated by the same clinician after treatment. All patients treated with Brazilian propolis gel and Daktarin® had complete clinical remission of palatal edema and erythema. This new Brazilian propolis gel formulation had efficacy comparable to Daktarin® and could be an alternative topical choice for the treatment of denture stomatitis. Copyright

Traumatismos maxilofaciais como marcadores de violência urbana uma análise comparativa entre gêneros

Urban violence is a widely discussed topic in various sectors of society, either due to its impact on public health indicators and its influence on the everyday life of individuals or the constant presence of casualties in the health services. This study compares differences in victimization between the genders based on maxillofacial injuries as markers of urban violence. This is a cross-sectional study with data collected in three hospitals of reference for multiple traumatic injuries in Belo Horizonte in the state of Minas Gerais, between January 2008 and December 2010. The analysis included descriptive and multivariate statistics using logistic regression. There were records of 7,063 victims, 55.1% of which involved interpersonal violence. The majority of victims were males (71.2%). Among the male victims, firearm and knife-inflicted aggression and motorcycle accidents were more frequent than aggression without the use of a weapon. Multiple fractures were the type of injury that best characterized the profile of victimization among males compared to soft tissue injuries. Gender is an important factor in victimization resulting in maxillofacial injuries and urban violence, in which males are the main victims.Urban violence is a widely discussed topic in various sectors of society, either due to its impact on public health indicators and its influence on the everyday life of individuals or the constant presence of casualties in the health services.

Maxillofacial Injuries as Markers of Interpersonal Violence in Belo Horizonte-Brazil: Analysis of the Socio-Spatial Vulnerability of the Location of Victim's Residences.

The aim of the present study was to analyze the spatial pattern of cases of maxillofacial injuries caused by interpersonal violence, based on the location of the victim’s residence, and to investigate the existence of conditions of socio-spatial vulnerability in these areas. This is a cross-sectional study, using the data of victims attended in three emergency hospitals in Belo Horizonte-Brazil between January 2008 and December 2010. Based on the process of spatial signature, the socio-spatial condition of the victims was identified according to data from census tracts. The spatial distribution trends of the addresses of victims were analyzed using Kernel maps and Ripley’s K function. Multicriteria analysis was used to analyze the territorial insertion of victims, using a combination of variables to obtain the degree of socio-spatial vulnerability. The residences of the victims were distributed in an aggregated manner in urban areas, with a confidence level of 99%. The highest densities were found in areas of unfavorable socioeconomic conditions and, to a lesser extent, areas with worse residential and neighborhood infrastructure. Spatial clusters of households formed in slums with a significant level of socio-spatial vulnerability. Explanations of the living conditions in segregated urban areas and analysis of the concentration of more vulnerable populations should be a priority in the development of public health and safety policies.

A violência urbana contra crianças e adolescentes em Belo Horizonte: uma história contada através dos traumas maxilofaciais

Os traumas maxilofaciais decorrentes da violencia contra criancas e adolescentes impactam suas vidas, fisica e psiquicamente, pelas deformidades que podem provocar e pela exposicao da lesao na face das vitimas. O objetivo deste trabalho e identificar a prevalencia dos traumas maxilofaciais em criancas e adolescentes decorrentes da violencia urbana em Belo Horizonte- Brasil. O estudo foi conduzido no Hospital Municipal Odilon Behrens, unico hospital municipal de referencia nesse tipo de atendimento em Belo Horizonte. Coletaram-se os registros de vitimas atendidas de janeiro a dezembro de 2007. O principal evento de violencia sofrido entre criancas e adolescentes foi agressao fisica, 44,2% e 64,7%, respectivamente. Entre as criancas, o tipo de trauma mais comum foi o trauma dentoalveolar (53,8%), e entre os adolescentes, trauma de tecidos moles (47,5%). O maior numero de ocorrencias se deu no periodo noturno: criancas (84,6%) e adolescentes (74,8%). O genero mais vitimado foi o masculino, criancas (63,5%) e adolescentes (68,3%). Estrategias apropriadas para identificacao do evento de violencia e do agressor sao necessarios para que melhor sejam planejados mecanismos de protecao da crianca e do adolescente, uma vez que a violencia sofrida por criancas e adolescentes no Brasil, considerando a complexidade dessa fase da vida, assume um quadro sombrio, desconstruindo o desenvolvimento, a sociabilidade e comprometendo a visao das vitimas sobre si mesmas e sobre o mundo que as cercam.

Miíase bucal e doença de Alzheimer: relato de caso clínico

Miiase e uma afeccao causada pela presenca de larvas de moscas em orgaos e/ou tecidos do homem ou de outros animais vertebrados, sendo mais frequentemente observada em paises tropicais. A ocorrencia de miiase na cavidade bucal e rara. Dentre os fatores predisponentes, destacam-se a senilidade, o comprometimento neurologico e a halitose. Assim, pacientes com doencas neuro-degenerativas, como a doenca de Alzheimer (DA), sao mais propensos a adquirirem essa alteracao. Este trabalho relata um caso de miiase bucal, acometendo um paciente de 67 anos de idade, com DA em fase avancada, totalmente dependente para as atividades de vida diaria (AVD), residente em uma instituicao de longa permanencia (ILP). O paciente apresentava falta de selamento labial e resistencia aos cuidados de higiene bucal. O diagnostico foi estabelecido clinicamente com base na observacao de sangramento na regiao anterior do palato, descolamento da mucosa bucal e presenca de larvas. Foi prescrito o uso de ivermectina e o paciente foi hospitalizado para debridamento do tecido necrotico e remocao das larvas. Apos a alta, os cuidadores foram orientados quanto ao uso de mascara pelo paciente, que nao se mostrou efetiva, pois o paciente passou a morde-la, levando a seu deslocamento e reinfestacao por larvas. Apos o tratamento da reinfestacao, adotou-se o uso de cortinado como rotina. Pacientes com DA constituem um grupo de risco para miiase bucal, sendo necessario orientar cuidadores e familiares em relacao aos cuidados odontologicos para a prevencao desta patologia. O principal tratamento para a alteracao baseia-se na remocao mecânica das larvas e instituicao do uso oral da ivermectina.

Stylohyoid complex ossification in temporomandibular disorder: A case-control study

STATEMENT OF PROBLEM Stylohyoid complex ossification (SCO) can be associated with temporomandibular disorder (TMD). However, this subject is poorly investigated in epidemiological studies. PURPOSE The purpose of this study was to assess the association between TMD and SCO. MATERIAL AND METHODS Seventy-eight individuals with TMD and 93 control individuals without TMD were enrolled in a case-control study and paired according to age and gender. Panoramic radiographs were made of all participants, and SCO was measured in millimeters (mm) by a blinded researcher. Ossification was held to begin at measurements of 30 mm or more. The association between symptoms (pain upon swallowing or turning the head and the sensation of a foreign body in the throat) and SCO was investigated. Pearson chi-square tests were used for the comparison of proportions, (α=.05). RESULTS A total of 44.9% of those with TMD and 46.2% of the control population exhibited SCO (P=.858). TMD was associated with pain upon swallowing (P<.05) and upon turning the head P<.01), but there were no associations between the symptoms possibly related to SCO and the presence of ossification (pain upon swallowing P=.658; sensation of a foreign body in the throat P=.980; pain upon turning the head P=.405). CONCLUSIONS The results suggest that there are no associations between TMD and SCO. Some symptoms classically associated with SCO also occur in TMD patients.

Padrão espacial e diferencial de renda dos domicílios de adolescentes e adultos jovens vítimas de traumatismo maxilofacial por agressão com arma de fogo

The study investigated the spatial pattern of cases of maxillofacial injury resulting from firearm aggression among teenagers and young adults and analyzed the comparison of income differentials in these areas based on the residence of the victims. This is a cross-sectional study with data from victims attended in three hospitals in Belo Horizonte, State of Minas Gerais, from January 2008 to December 2010. The addresses of the victims were georeferenced by geocoding. Randomness and point density trends were analyzed using Ripleys K function and Kernel maps. The spatial interaction between the homes of adolescents and young adults was verified through the K12 function. Records of 218 cases of assault with a male predominance (89.9%) and young adults (70.6%) were found. Household clusters were distributed on an aggregate basis in the urban space with a confidence level of 99% and similar spatial aggregation levels. The hotspots converged on 7 shantytowns or neighboring regions with higher income population revealing spread of events. Hotspots focused on slums with a history of crimes linked to drug trafficking. The incorporation of space in the dynamics of events showed that the economic condition in isolation did not limit victimization.Resumo O estudo investigou o padrao espacial dos casos de traumatismo maxilofacial decorrentes de agressao com arma de fogo em adolescentes e adultos jovens a partir do local de domicilio das vitimas e analisou comparativamente os diferenciais de renda dessas areas. Estudo transversal com dados de vitimas atendidas em tres hospitais de Belo Horizonte-MG, entre janeiro de 2008 e dezembro de 2010. Enderecos foram georeferenciados por geocodificacao. Tendencias de aleatoriedade e densidade de pontos foram analisadas por Funcao K de Ripley e mapas de Kernel. A interacao espacial entre os domicilios de adolescentes e adultos jovens foi verificada atraves da Funcao K12. Encontrouse registros de 218 casos de agressao com arma de fogo, com predominio do sexo masculino (89,9%) e adultos jovens (70,6%). Os domicilios se distribuiram de forma agregada no espaco urbano com nivel de confianca de 99% e niveis de agregacao espacial semelhantes. Os clusters de domicilios convergiram para 7 favelas ou regioes vizinhas com populacao de maior renda revelando propagacao de eventos. Os hotspots se concentraram em favelas com historico de crimes ligados ao narcotrafico. A incorporacao do espaco na dinâmica dos eventos mostrou que a condicao economica isoladamente nao limitou a vitimizacao.
