Chorea and ballism are movement disorders that result from a variety of conditions. Hyperglycemia is an unusual recognized cause of these movement disorders. We report 3 cases of new-onset choreaballism induced by nonketotic hyperglycemia in elderly patients, highlighting that chorea may be the first manifestation of undiagnosed decompensated diabetes mellitus.

Several components of the erythrocyte-dependent glutathione redox system (reduced glutathione, GSH; oxidized glutathione, GSSG; glutathione peroxidase, GSH-Px; glutathione reductase, GSH-Red) were determined in patients with types I and II diabetes mellitus (DM). All groups studied were male subjects: G1, 20 young healthy individuals (aged 23.7 +/- 4.2 years); G2, 15 young insulin-treated type I DM patients; G3, 20 older insulin-treated type II DM patients; 04, 21 older oral hypoglycemic agent-treated type II DM patients; G5, 28 aged healthy individuals (aged 68.9 +/- 11.5 years). There were no differences between G1 and G2, G3 or G4 regarding erythrocyte GSH, GSSG, and GSH-Red (without FAD) levels. GSH-Px activity was significantly lower in G2 when compared to G1 (15.2 +/- 4.9 vs 20.6 +/- 6.6 IU/g Hb). The GSH-Red and GSH-Px activities and GSH levels were significantly higher in 03 (4.6 +/- 1.7 IU/g Hb, 20.2 +/- 8.7 IU/g Hb and 3.5 +/- 1.3-mu-M/g Hb) and G4 (5.0 +/- 2.2 IU/g Hb, 16.9 +/- 6.1 IU/g Hb and 5.0 +/- 2.3-mu-M/g Hb) when compared to G5 (3.4 +/- 0.9 IU/g Hb, 12.0 +/- 3.6 IU/g Hb and 2.3 +/- 0.9-mu-M/g Hb). The findings suggest that treatment of DM can stimulate the redox activity of red blood cells in aged subjects.

Plants have been used in the cure of diseases from the origins of the humanity. At present, in Brazil, the use is common because of the difficulty of access of part of the population to medical assistance. It is commonly believed that the medicinal plants of traditional use were already tested and ratified by the long-lasting use by the human species, being considered effective medicines, presenting no collateral effects, not needful, therefore, of evaluation. The miraculous self-medication with medicinal plants goes to the point of substituting therapies in serious diseases such as those of hypoglycemic or anti-diabetic effect. For the test of medicinal plants, it is necessary to consider the material quality to be tested, the plant component used, extraction method, dosage, and the experimental species used. Several plants have already had hypoglycemic effects proven experimentally. The objective of this paper was to accomplish a revision of Brazilian medicinal plants, used popularly, as hypoglycemics that had effects proven in animals and in humans.

The oral rehabilitation by dental implants in patients with diabetes remains a controversial issue. The aim of this study was to evaluate the influence of diabetes mellitus and insulin therapy on the bone healing around dental implants using torque removal. Twenty-seven rabbits were randomly divided into 3 groups with 9 animals each: control (C) group, induced diabetic (D) group, and insulin-treated diabetic (ITD) group (10 U/day). After 1 week, one implant was inserted at the tibial metaphysis of the animals. The glucose levels were periodically evaluated through the glucose-oxidase enzymatic method. The animals were killed at 4, 8, and 12 weeks after surgery and the biomechanical test was performed using a torque manometer. Statistically significant differences regarding the removal torque of the implant could not be found at 4 weeks (P = 0.2) among groups. Group C showed statistically higher values than groups D and ITD at the experimental periods of 8 (P = 0.0001 and P = 0.0002, respectively) and 12 weeks (P = 0.0053 and P = 0.001, respectively). There were no statistical differences between D and ITD groups in any of the experimental periods. Diabetes mellitus has negatively influenced the mechanical retention of implants placed at the tibial metaphysis of rabbits. Therapy with insulin did not induce any changes.

We evaluated insulin release and insulin sensitivity in women with basal and/or postprandial hyperglycemia but normal oral glucose tolerance test (OGTT) in previous pregnancy (GHG). These women were individually matched with females without previous hyperglycemia (NGT). Both groups consisted of normal glucose-tolerant women at the time of this study. They underwent OGTT (75g; n= 32 pairs) and hyperglycemic clamp experiments (10mmoll-1; n=27 pairs) with plasma glucose, insulin, and C-peptide measurements and calculation of insulinogenic index, first- and second-phase insulin release, and insulin sensitivity index (ISI). The GHG group showed higher glycosylated hemoglobin levels (6.2±0.6% versus 5.8±0.8%; P<0.05); lower insulinogenic index at 30min (134.03±62.69pmolmmol-1 versus 181.59±70.26pmolmmoll-1; P<0.05) and diminished C-peptide response in relation to glucose (4.05±0.36nmolmmol-1 versus 4.23±0.36nmolmmol-1; P<0.05) at OGTT. Both groups did not show difference in insulin secretion and ISI by hyperglycemic clamp technique. We concluded that in up to 12 years from index pregnancy, women with previous GHG, presenting normal glucose tolerance and well-matched with their controls, showed β-cell dysfunction without change in ISI. As women with previous GHG are at risk of type 2 diabetes, β-cell dysfunction may be its primary defect. © 2003 Elsevier B.V. All rights reserved.

Diabetes Mellitus may lead to alterations in the eyes, kidneys, cranial nerves, peripheral nerves, ears etc. The cognitive function, also, seems to be compromised in subjects presented with Diabetes Mellitus, since the cortical and subcortical structures responsible for this function are hindered in some insulin-dependent patients. The cognitive potential P300 has been used as an objective procedure to assess cerebral cognitive functions. Objective: Analyze the sensitivity of P300 cognitive potential for the detection of alterations on the auditory cortex secondary to Diabetes Mellitus. Study design: transversal cohort. Material and Method: Sixteen diabetic subjects of both genders aged 7 to 71 years, and seventeen non-diabetic individuals at the same age range participated in this study, the evaluation procedures were pure tone audiometry (PTA) and P300 cognitive potential. Glycemia of the group presented with Diabetes was assessed prior to applying the P300. Results: No statistically significant difference was shown for the PTA results. A statically significant difference was observed between groups when analyzing the latency of the P300 component measured in Fz. there was a correlation between glycemia and the latency and amplitude of P300. Conclusion: The investigation of the cognitive potential of P300 is an important procedure for the prevention and early diagnosis of neurological changes in individuals presented with Diabetes Mellitus.

The main causes of illness and consequent death in patients affected by Diabetes Mellitus are the long-term complications. Depression can make it harder to control the level of glucose in the blood, as well as intensifying and worsening the clinical complications, thus reducing the quality of life. The aim of this study was to estimate the incidence of Diabetes Mellitus in Public Health Clinic in Presidente Prudente (SP) in patients enrolled in the Hiper-Dia Program. From October 2003 to July 2004, a descriptive survey was carried out. Data were obtained from doctor's records of 50 diabetes patients and also their answers to a specific questionnaire. The majority of the patients were female, had not completed elementary school, with a family income below five minimum wages, a nationally-defined amount related to the poverty line. It was observed that 24% of the patients had depression and 76% never followed a controlled diet. Pharmacological treatment was prescribed for 82% of the patients. Twenty-eight patients were receiving psyicological treatment, together with oral hypoglycemic agents. The glycated hemoglobin was measured in 68%. The association between depression and submission to treatment was not significant. No statistical association was found between the psychologically assisted patient's group and glucose control (p= 0.40), diet control (p= 0.37) and physical activities (p= 0.77). It was concluded that 24% patients had depression and the majority not under diet control, but 82% were under pharmacological treatment.

The aim of this study was to analyze the risk factors related to the cardiovascular diseases (CVRF) in elderly type 2 diabetics. A cross-sectional observational study was carried out on 100 elderly patients attending the Rehabilitation Center of Araraquara (CRRA), São Paulo State, Brazil, from March to December, 2004. The majority were married, female, white, with a low income and low educational level. Regarding habits and style of life, the subjects had an adequate diet, were sedentary, non-smoking and non-drinking. In the population of 100, 42% were overweight, 42% obese, 71% had above-normal waist measurements and 84% high waist-to-hip ratios. Concerning the CVRF, it was observed that more than half had hypertension, hypercholesterolaemia and hypertriglyceridaemia. 84% had high values of LDL-cholesterol and 59% HDL-cholesterol levels below the reference values, 78% high levels of fasting glycemia, 76% glycohemoglobin and 57% fibrinogen and thus subject to cardiovascular risk. The results showed a high frequency of cardiovascular risk factors, differing according to sex and the age.

Several studies have shown that diabetics are more susceptible to the development of severe periodontal disease. Currently, the use of animal models can be considered a feasible alternative in radiographic assessments of these two pathologies. The purpose of this radiographic study was to evaluate the effect of induced diabetes mellitus on alveolar bone loss after 30 days of ligature-induced periodontal disease. Sixty-four Wistar rats were randomly distributed into four experimental groups. Diabetes was induced in Groups II and IV, while periodontal disease was induced in Groups III and IV; Group I was used as control. In order to perform the radiographic assessment of the specimens, the rats were killed on the 3rd and 30th days of the study. Radiographic measurements were assessed with ANOVA and Tukey's test to determine statistically significant differences (p < 0.05). It was observed that Groups III and IV featured greater bone loss when compared to Groups I and II. Only the diabetic group with periodontal disease (Group IV) featured statistically significant greater bone loss when compared to the other groups. These results suggested that the alveolar bone loss resulting from the periodontal disease installation is greater when associated to the diabetes mellitus.
