Osterradionecrose dos maxilares

The osteoradionecrosis (ORN) during long was considered as hum type of osteomyelitis spent bone, being one of the major complications of radiotherapy head and neck. This complicate are presents despite advances in the treatment of cancer patients, Therefore, the objective of this work was to emphasize the main factors predisposing ORN, its clinical features and treatment through a literature review.

Opportunistic microorganisms in patients with head and neck trauma

The use of antimicrobial agents has facilitated the dissemination of multi-resistant microorganisms, compromising dental and medical treatment. The aim of this study was to evaluate the distribution of different opportunistic microbial species in patients who suffered head and neck trauma, under temporary maintenance in nosocomial environment, particularly intensive care units, on the occurrence of such microorganisms in the oral cavity of the patients. It was selected 38 patients subjected to head and neck traumas. After emergency surgical procedures, clinical samples of saliva, sub and supragingival biofilms and mucosal surfaces were collected at two different moments: just after stabilization of the patient and soon after patients’ release from medical units. The presence of opportunistic and superinfecting microorganisms was evaluated by culture on selective and non-selective media, and the presence of the family Enterobacteriaceae, as well as genera Enterococcus, Pseudomonas, and Staphylococcus was assessed by PCR. It was found that the use of antimicrobials, even for short periods of time was sufficient to facilitate colonization by microorganisms of the families Enterobacteriaceae and Pseudomonadaceae, as well as yeasts and enterococci. These results support the concept that medical and dental teams should make a periodically change of antimicrobials used in treatment protocols in hospital for head and neck trauma patients, in order to minimize dissemination of opportunistic or superinfecting microorganisms.

Qualidade de vida de pacientes submetidos à radioterapia para tratamento de lesões malignas de cabeça e pescoço

In order to evaluate the quality of life of patients with head and neck cancer, this study analyzed data of 24 patients with squamous cell carcinoma, which indicated therapy was radiotherapy or not be combined with chemotherapy and surgery. The study was conducted in the Unit of Radiotherapy of Megavoltage located in the São José de Rio Preto-SP, in the period August 2007 to January 2008. Then, it was used the questionnaire of quality of life from University of Washington which enabled the identification of different quality of life patterns associated with the different stages of radiotherapy, indicating to be viable the prospect of recognition of prognostic factors of reduction in multiple domains of quality of life. From the data collected and analyzed, it was identified that the areas with the worst score in the begin of radiotherapy were appearance, speech and anxiety; during the treatment were taste, saliva and anxiety; and in the end were taste, saliva and swallowing. Throughout the treatment, it was observed the deterioration of patients' mood. In this regard, emphasizes the importance of dental and psychological follow-up, within the framework of a multidisciplinary care for patients with head and neck cancer during radiotherapy treatment.

Modeling spatial distribution of cancer incidence in Cordoba, Argentina

Background: Cancer is the second leading cause of death in Argentina, and there is little knowledge about its incidence. The first study based on population-based cancer registry described spatial incidence and indicated that there existed at least county-level aggregation. The aim of the present work is to model the incidence patterns for the most incidence cancer in Córdoba Province, Argentina, using information from the Córdoba Cancer Registry by performing multilevel mixed model approach to deal with dependence and unobserved heterogeneity coming from the geo-reference cancer occurrence. Methods: Standardized incidence rates (world standard population) (SIR) by sex based on 5-year age groups were calculated for 109 districts nested on 26 counties for the most incidence cancers in Cordoba using 2004 database. A Poisson twolevel random effect model representing unobserved heterogeneity between first level-districts and second level-counties was fitted to assess the spatial distribution of the overall and site specific cancer incidence rates. Results: SIR cancer at Córdoba province shown an average of 263.53±138.34 and 200.45±98.30 for men and women, respectively. Considering the ratio site specific mean SIR to the total mean, breast cancer ratio was 0.25±0.19, prostate cancer ratio was 0.12±0.10 and lower values for lung and colon cancer for both sexes. The Poisson two-level random intercepts model fitted for SIR data distributed with overdispersion shown significant hierarchical structure for the cancer incidence distribution. Conclusions: a strong spatial-nested effect for the cancer incidence in Córdoba was observed and will help to begin the study of the factors associated with it.

The use of body circumferences for the prediction of intra-abdominal fat in obese women with polycystic ovary syndrome

Introduction: Computerizd tomography (CT) is the gold standard for the evaluation of intra- (IAF) and total (TAF) abdominal fat; however, the high cost of the procedure and exposure to radiation limit its routine use. Objective: To develop equations that utilize anthropometric measures for the estimate of IAF and TAF in obese women with polycystic ovary syndrome (PCOS). Methods: The weight, height, BMI, and abdominal (AC), waist (WC), chest (CC), and neck (NC) circumferences of thirty obese women with PCOS were measured, and their IAF and TAF were analyzed by CT. Results: The anthropometric variables AC, CC, and NC were chosen for the TAF linear regression model because they were better correlated with the fat deposited in this region. The model proposed for TAF (predicted) was: 4.63725 + 0.01483 x AC - 0.00117 x NC - 0.00177 x CC (R-2 = 0.78); and the model proposed for IAF was: IAF (predicted) = 1.88541 + 0.01878 x WC + 0.05687 x NC - 0.01529 x CC (R-2 = 0.51). AC was the only independent predictor of TAF (p < 0.01). Conclusion: The equations proposed showed good correlation with the real value measured by CT, and can be used in clinical practice.

Desafios à organização de programa de rastreamento do câncer do colo do útero em Manaus-AM

Objetivou-se identificar as características sociodemográficas das mulheres que realizam o Papanicolaou em Manaus, Amazonas, e sua associação com os motivos para realização do exame. Pesquisa exploratória incluindo 281 mulheres, que haviam realizado o Papanicolaou nos últimos cinco anos em Manaus. A maioria das entrevistadas tinha entre 18-34 anos (54%), 5-11 anos de estudo (54,4%), renda familiar mensal de até três salários mínimos (84,3%), relação estável (72,2%) e início da vida sexual entre 15-19 anos (69,4%). Os motivos para realização do Papanicolaou foram procura espontânea (66,2%), recomendação médica (23,5%) e sintomas ginecológicos (10,3%). Mulheres que receberam informação dos profissionais de saúde tiveram proporção maior de realização do exame nos últimos três anos (p=0,008). A demanda espontânea é prevalente e o atendimento oportunístico é realizado nas mulheres mais jovens, não alcançando o grupo com maior risco para o câncer. É necessário implantar estratégias de recrutamento ativo alcançando mulheres em desvantagem socioeconômica.

A avaliação da rede venosa pela enfermagem em mulheres com câncer ginecológico durante o tratamento quimioterápico

Estudo de abordagem exploratória e descritiva que teve como objetivos: avaliar a rede venosa das mulheres com câncer cérvico uterino, no início e ao final do tratamento quimioterápico; analisar a ocorrência de flebite provocada pelas drogas utilizadas nos protocolos de quimioterapia neoadjuvante e adjuvante e relacionar os tipos de veia com os dispositivos mais utilizados, tempo de permanência e intercorrências. Utilizou-se um instrumento de avaliação da rede venosa para os membros superiores. Foram incluídas 20 mulheres atendidas em um hospital de ensino do interior do Estado de São Paulo. A avaliação da rede venosa demonstrou poucas alterações, e a intercorrência mais frequente foi o hematoma (60%). Os resultados deste estudo apontam para aspectos da prática de enfermagem relacionados à administração de quimioterápicos e ressaltam a necessidade de elaborar e implantar protocolos para o cuidado.
