Condi??es socioecon?micas e cancer de cabe?a e pesco?o: uma revis?o sistemática de literatura
Boing,Antonio Fernando; Antunes,José Leopoldo Ferreira;
Ciência & Saúde Coletiva , 2011, DOI: 10.1590/S1413-81232011000200025
Abstract: this study sought to describe the main characteristics of epidemiological studies that investigated the association between socioeconomic conditions and head and neck cancer. research was carried out on the medline (international science literature), lilacs (latin american and caribbean health sciences literature) and scielo (scientific electronic library online) databases, as well as the references cited in the articles obtained through the primary search of the aforementioned databases. the publication period considered included 38 years (1970-2007) and the analysis was restricted to articles in spanish, english or portuguese. twenty-five studies were selected, 15 that outlined case-control, four ecological and six that combined information from official databases, such as censuses and cancer or death records. most cases reported an association between lower socioeconomic conditions and head and neck cancer. the most used indexes were occupation and education. few studies investigated medication, aiming to point out which proximal factors operate in the investigated association. additional studies, with uniform criteria to effect the adjustments in the regression models and sufficient samples, are required to inquire this dimension.

Melo, Antonio Antunes,Le?o, Fernando Souza,Campos, Alexandre José Costa,Antunes, Maria do Rosário Távora de Arruda
International Archives of Otorhinolaryngology , 2011,
Abstract: Introduction: At the differentiated diagnosis of asymmetrical sensorineural hearing losses, vascular disorders are present, one of which is megadolicho basilar artery. This disease is generally asymptomatic, and when symptoms are found, they can be caused by a compression or ischemia. Clinically, sensorineural hearing loss, tinnitus, headache, facial hypoesthesia, trigeminal neuralgia, vertigo, diplopia and facial palsy, among others, are likely to occur. The image examination of choice for its diagnosis is nuclear magnetic resonance. The megadolicho basilar artery therapy can be surgical or conservative, according to the associated findings. A multidisciplinary approach, including a neurologist, neurosurgeon and an otorhinolaryngologist is recommended for a proper administration of the case. Objective: Report the case of a patient with asymmetrical sensorineural hearing loss, diagnosed of megadolicho basilar artery. Case report: JBS, 57-year-old white male with a history of asymmetrical sensorineural hearing loss and bilateral whistle-like tinnitus for several years. The otorhinolaryngologic evaluation, including otoscopy, anterior rhinoscopy and oral pharynx, was normal. Final Comments: The treatment consisted in following up with the patient, controlling the tinnitus by drugs and using an individual sound amplification apparatus on the left ear.

Abstract: socioeconomic differences have effects on epidemiological profile of cancer as regards incidence, mortality, survival and quality of life after diagnosis. in this study are examined the inequalities of cancer occurrence in the brazilian population and summarized the evidences of epidemiological research on social determinants in cancer. the main factors that modulate the influence of socioeconomic conditions in cancer are considered, such as smoking, alcohol consumption, diet and obesity, occupation, and access to health services. modifications of social conditions depend on broader changes in society, as improvements of educational level; however, well-conducted epidemiological investigations can instruct the planning of interventions aimed at reducing the impact of social determinants on cancer. these studies should focus on methods to improve the quality of information on incidence and mortality; regular population surveys on the prevalence of cancer risk factors; study designs to examine cancer etiological factors in its relations with social status; implementation and assessment of effectiveness of screening programs for early detection of tumors; and evaluation of access to diagnosis and treatment. these researches should include populations in different regions of the world, particularly those living in places that lack the benefits provided by the dynamics of the present global economic system.

Revista Panamericana de Salud Pública , 2006, DOI: 10.1590/S1020-49892006000700001
Abstract: objective: to investigate the trends and regional patterns in mortality from oral cancer and pharyngeal cancer in brazil from 1979 through 2002. methods: data were obtained from the mortality information system (sistema de informa??es sobre mortalidade) database, which is compiled by the ministry of health of brazil. mortality rates were adjusted by gender and age. the prais-winsten generalized linear regression procedure was used to calculate the annual increase or decrease in mortality rates. the time trends for mortality due to oral cancer and to pharyngeal cancer were analyzed by specific anatomical site and by region of the country (north, northeast, south, southeast, and center-west). results: in all five regions of brazil over the period studied, oral cancer mortality remained stable for both genders, but pharyngeal cancer mortality increased for both genders. mortality from cancer affecting the lips, tongue, gums, mouth floor, palate, other parts of the mouth, and tonsils showed a statistically significant decrease over the period. however, mortality from cancer affecting the oropharynx, hypopharynx, and ill-defined and undefined sites of the oral cavity and the pharynx showed a significant increase. mortality rates for both oral cancer and pharyngeal cancer were higher in the south and southeast regions of the country than in brazil's three other regions. conclusions: the relatively larger decrease in mortality from cancer affecting the lips, gums, and other anatomical sites more easily accessible to clinical inspection suggests a possible link between oral and pharyngeal cancer survival and an improved provision of health care services in brazil in recent decades.

Abstract: the objective of this study was to review the brazilian epidemiologic literature on periodontal outcomes and socio-demographic factors, assessing bibliographic and methodological characteristics of this scientific production, as well as the consistency and statistical significance of the examined associations. a systematic review was carried out in six bibliographic sources. the review was limited to the period between 1999 and 2008, without any other type of restriction. among the 410 papers identified, 29 were included in the review. an increasing number of articles, specifically in the last four years of study, was observed. however, there is a concentration of studies in the south and southeast regions of brazil, and many of them are not closely connected to theoretical formulations in the field. in spite of these shortcomings, the review findings corroborate the idea that poor socioeconomic conditions are associated with periodontal outcomes, as demonstrated primarily by income and schooling indicators.

Abstract: several epidemiological studies have analyzed the association between oral health and social development. however, the use of different variables assessing socioeconomic status impairs the comparative analysis of their findings. the present study describes how recent dental studies have classified population segments according to categories of social stratification. we selected 86 papers on social determinants of dental caries or periodontal conditions, and published in medline-indexed journals from 1990 to 2001. the studies used different strategies to stratify populations, but occupation, schooling, and income were the most frequently assessed variables. ethnic differentials, characteristics of households and schools, and access to material resources were also frequently appraised. we also observed a large portion of brazilian studies focusing on socioeconomic differentials in the distribution of caries and periodontal disease. knowledge of strategies for social stratification can improve the understanding of factors associated with dental diseases, fostering further studies and allowing the comparison of their results.

Abstract: Alcohol drinking and tobacco smoking are assumed to have significant independent and joint effects on oral cancer (OC) development. This assumption is based on consistent reports from observational studies, which, however, overestimated the independent effects of smoking and drinking, because they did not account for the interaction effect in multivariable analyses. This case-control study sought to investigate the independent and the joint effects of smoking and drinking on OC in a homogeneous sample of adults. Case patients (N = 1,144) were affected by invasive oral/oropharyngeal squamous cell carcinoma confirmed histologically, diagnosed between 1998 and 2008 in four hospitals of S?o Paulo (Brazil). Control patients (N = 1,661) were not affected by drinking-, smoking-associated diseases, cancers, upper aero-digestive tract diseases. Cumulative tobacco and alcohol consumptions were assessed anamnestically. Patients were categorized into never/ever users and never/level-1/level-2 users, according to the median consumption level in controls. The effects of smoking and drinking on OC adjusted for age, gender, schooling level were assessed using logistic regression analysis; Model-1 did not account for the smoking-drinking interaction; Model-2 accounted for this interaction and included the resultant interaction terms. The models were compared using the likelihood ratio test. According to Model-1, the adjusted odds ratios (ORs) for smoking, drinking, smoking-drinking were 3.50 (95% confidence interval –95CI, 2.76–4.44), 3.60 (95CI, 2.86–4.53), 12.60 (95CI, 7.89–20.13), respectively. According to Model-2 these figures were 1.41 (95CI, 1.02–1.96), 0.78 (95CI, 0.48–1.27), 8.16 (95CI, 2.09–31.78). Analogous results were obtained using three levels of exposure to smoking and drinking. Model-2 showed statistically significant better goodness-of-fit statistics than Model-1. Drinking was not independently associated with OC, while the independent effect of smoking was lower than expected, suggesting that observational studies should be revised adequately accounting for the smoking-drinking interaction. OC control policies should focus on addictive behaviours rather than on single lifestyle risk factors.
