Avaliação da relação entre diabetes mellitus e doença periodontal: um estudo em pacientes pertencentes à Casa do Diabético no município de Belém-PA

O diabetes mellitus é uma doença caracterizada por anormalidades endócrinas e matabólicas, que resulta em alterações em muitos setores do organismo. Ao passo que a doença periodontal é uma lesão infecto-inflamatória que envolve os tecidos de sustentação dos dentes. Convém, esclarecer a relação entre o diabetes mellitus e a doença periodontal por uma associação biológica, na qual diabéticos apresentam deficiência na resposta orgânica e aumento da suscetibilidade para muitos tipos de infecção, incluindo a infecção perioodntal. Este trabalho tem como objetivo comparar indivíduos com adequado controle metabólico do diabetes mellitus e indivíduos com pobre controle glicêmico da doença, em diferentes tempos de duração do diabetes. Foram avaliados periodontalmente 31 indivíduos com controle glicêmico adequado e 29 sujeitos com pobre controle metabólico. Os resultados revelaram que a condições de higiene bucal e de inflamação gengival são similares entre os indivíduos com diferentes anos de diabetes, independente da qualidade do controle metabólico do diabetes mellitus. A profundidade de sondagem revelou maior severidade em indivíduos com mais de cinco anos de doença, principalmente no grupo com pobre controle glicêmico. Em conclusão, indivíduos diabéticos com mais de cinco anos de duração da doença e com pobre controle metabólico do nível de glicemia apresentam maiores perdas de estrutura periodontal.

Estudo comparativo das representações sociais sobre diabetes mellitus e pé diabético

The study aimed to investigate social representations of the terms diabetes and diabetic foot in different populations. Participants were divided into groups: diabetics (GD); non- diabetics (GN); and non-diabetic healthcare professionals (GP). Personal data were collected, and subjects answered two questions that were expected to evoke five words that came to mind when they thought of diabetes and then diabetic foot. The evoked material was analyzed with the software Ensemble de Programmes Permettant l'Analyse dês Èvocations. A total of 161 subjects participated, including GD (n = 72) with a mean age of 56.12 ± 5.49 years; GN (n = 38) with a mean age of 54.29 ± 7.91 years; and GP (n = 51) with 34.95 ± 7.52 years. The term diabetes evoked 297 words in GD, 172 in GN, and 235 words in GP. The term diabetic foot evoked 180 words in GD, 90 in GN, and 236 in GP. The groups proved to be anxious for more information, thus confirming the need for awareness-raising and educational programs on diabetes, covering comprehensive issues concerning the disease.

Revascularisation of coronary artery disease in patients with diabetes mellitus

Diabetes mellitus is becoming increasingly prevalent and magnifies the risk of cardiovascular complications. Endothelial dysfunction caused by oxidative stress is a hallmark of diabetes and is responsible for the ubiquitous manifestations of vascular disease in diabetics. Compared with non-diabetic patients, coronary artery disease is more severe and the clinical outcome impaired in diabetic patients undergoing revascularisation. Despite these limitations the benefit of revascularisation therapy is particularly pronounced in diabetics. The optimal revascularisation strategy (coronary artery bypass graft surgery versus percutaneous coronary intervention) in diabetic patients with coronary artery disease depends on clinical and anatomical considerations.

Macular edema in Hispanics with non-insulin dependent diabetes mellitus in Starr County, Texas: Prevalence, incidence and risk factors

This project is based on secondary analyses of data collected in Starr County, Texas from 1981 till 1991 to determine the prevalence, incidence and risk factors for macular edema in Hispanics with non-insulin-dependent diabetes in Starr County, Texas. Two studies were conducted. The first study examined the prevalence of macular edema in this population. Of the 310 diabetics that were included in the study 22 had macular edema. Of these 22 individuals 9 had clinically significant macular edema. Fasting blood glucose was found to be significantly associated with macular edema. For each 10 mg/dl increase in fasting blood glucose there was a 1.07 probability of an increase in the risk of having macular edema. Individuals with fasting blood glucose $\ge$200 mg/dl were found to be more than three times at risk of having macular edema compared to those with fasting blood glucose $<$200 mg/dl.^ In the second study the incidence and the risk factors that could cause macular edema in this Hispanic population were examined. 240 Hispanics with non-insulin-dependent diabetes mellitus and without macular edema were followed for 1223 person-years. During the follow-up period 27 individuals developed macular edema (2.21/100 person-years). High fasting blood glucose and glycosylated hemoglobin were found to be strong and independent risk factors for macular edema. Participants taking insulin were 3.9 times more at risk of developing macular edema compared to those not taking insulin. Systolic blood pressure was significantly related to macular edema, where each 10 mmHg increase in systolic blood pressure was associated with a 1.3 increase in the risk of macular edema.^ In summary, this study suggests that hyperglycemia is the main underlying factor for retinal pathological changes in this diabetic population, and that macular edema probably is not the result of sudden change in the blood glucose level. It also determined that changes in blood pressure, particularly systolic blood pressure, could trigger the development of macular edema.^ Based on the prevalence reported in this study, it is estimated that 35,500 Hispanic diabetics in the US have macular edema. This imposes a major public health challenge particularly in areas with high concentration of Mexican Americans. It also highlights the importance of public health measures directed to Mexican Americans such as health education, improved access to medical care, and periodic and careful ophthalmologic examination by ophthalmologists knowledgeable and experienced in the management of diabetic macular edema. ^

A GENETIC MARKER STUDY OF NON - INSULIN DEPENDENT DIABETICS IN THE MEXICAN-AMERICAN COMMUNITY FROM STARR COUNTY, TEXAS (PLASMA GLUCOSE, HEMOGLOBIN ANALYSIS)

Diabetes mellitus occurs in two forms, insulin-dependent (IDDM, formerly called juvenile type) and non-insulin dependent (NIDDM, formerly called adult type). Prevalence figures from around the world for NIDDM, show that all societies and all races are affected; although uncommon in some populations (.4%), it is common (10%) or very common (40%) in others (Tables 1 and 2).^ In Mexican-Americans in particular, the prevalence rates (7-10%) are intermediate to those in Caucasians (1-2%) and Amerindians (35%). Information about the distribution of the disease and identification of high risk groups for developing glucose intolerance or its vascular manifestations by the study of genetic markers will help to clarify and solve some of the problems from the public health and the genetic point of view.^ This research was designed to examine two general areas in relation to NIDDM. The first aims to determine the prevalence of polymorphic genetic markers in two groups distinguished by the presence or absence of diabetes and to observe if there are any genetic marker-disease association (univariate analysis using two by two tables and logistic regression to study the individual and joint effects of the different variables). The second deals with the effect of genetic differences on the variation in fasting plasma glucose and percent glycosylated hemoglobin (HbAl) (analysis of Covariance for each marker, using age and sex as covariates).^ The results from the first analysis were not statistically significant at the corrected p value of 0.003 given the number of tests that were performed. From the analysis of covariance of all the markers studied, only Duffy and Phosphoglucomutase were statistically significant but poor predictors, given that the amount they explain in terms of variation in glycosylated hemoglobin is very small.^ Trying to determine the polygenic component of chronic disease is not an easy task. This study confirms the fact that a larger and random or representative sample is needed to be able to detect differences in the prevalence of a marker for association studies and in the genetic contribution to the variation in glucose and glycosylated hemoglobin. The importance that ethnic homogeneity in the groups studied and standardization in the methodology will have on the results has been stressed. ^

CRISE DE IDENTIDADE EM ADOLESCENTES PORTADORES DO DIABETES MELLITUS DO TIPO I

A adolescência é um processo dinâmico entre a infância e a idade adulta: inicia-se com a puberdade e termina com a aquisição da identidade, da autonomia, bem como da elaboração de projetos de vida e de integração na sociedade. Os modelos de identidade são transferidos dos pais para os adolescentes, de modo a permitir a construção de idéias e afetos próprios. Este estudo tem como objetivo identificar como o adolescente vivencia tornar-se portador da doença crônica o diabetes. Para tanto, recorremos a abordagem qualitativa, utilizando como instrumento de coleta a entrevista semi-estruturada. Participaram do estudo cinco sujeitos, com idade variando de 10 a 17 anos, com diagnóstico do diabetes mellitus tipo 1 há pelo menos um ano. A partir das entrevistas, organizamos os dados em três temas: o impacto do diagnóstico no adolescente, convivendo com mudanças e a busca de identidade. Considerando-se que a adolescência é um período de vida marcado pela busca da identidade, no qual o adolescente esta revendo suas posições infantis frente a incerteza dos papéis adultos que se apresentam a ele, e aliado a este momento vem a doença crônica o diabetes. Parece-nos importante que haja compreensão, um grande apoio social e um efetivo trabalho de educação em diabetes que possibilitará a integração social e psicológica do portador do diabetes.

Short-term stability in refractive status despite large fluctuations in glucose levels in diabetes mellitus type 1 and 2

Purpose: This work investigates how short-term changes in blood glucose concentration affect the refractive components of the diabetic eye in patients with long-term Type 1 and Type 2 diabetes. Methods: Blood glucose concentration, refractive error components (mean spherical equivalent MSE, J0, J45), central corneal thickness (CCT), anterior chamber depth (ACD), crystalline lens thickness (LT), axial length (AL) and ocular aberrations were monitored at two-hourly intervals over a 12-hour period in: 20 T1DM patients (mean age ± SD) 38±14 years, baseline HbA1c 8.6±1.9%; 21 T2DM patients (mean age ± SD) 56±11 years, HbA1c 7.5±1.8%; and in 20 control subjects (mean age ± SD) 49±23 years, HbA1c 5.5±0.5%. The refractive and biometric results were compared with the corresponding changes in blood glucose concentration. Results: Blood glucose concentration at different times was found to vary significantly within (p<0.0005) and between groups (p<0.0005). However, the refractive error components and ocular aberrations were not found to alter significantly over the day in either the diabetic patients or the control subjects (p>0.05). Minor changes of marginal statistical or optical significance were observed in some biometric parameters. Similarly there were some marginally significant differences between the baseline biometric parameters of well-controlled and poorly-controlled diabetic subjects. Conclusion: This work suggests that normal, short-term fluctuations (of up to about 6 mM/l on a timescale of a few hours) in the blood glucose levels of diabetics are not usually associated with acute changes in refractive error or ocular wavefront aberrations. It is therefore possible that factors other than refractive error fluctuations are sometimes responsible for the transient visual problems often reported by diabetic patients. © 2012 Huntjens et al.
