The survival of the population has increased gradually and it is correlated with quality of health services and general living conditions, being particularly marked in industrialized countries. The increase in life expectancy affects the incidence of age-associated diseases. Aging is considered a risk factor for the development of neurodegenerative diseases like Alzheimer’s disease (AD). One theory on the pathogenesis of AD postulates that neurodegeneration is the result of oxidative stress and damage to vulnerable cerebral tissues. The fact that aging is a risk factor in AD also reinforces the hypothesis of free radicals involvement, because the effects of their actions can accumulate for years. It is an insidious, progressive disease and is characterized clinically by progressive loss of memory and other cognitive functions, as well as behavioral and social changes. The memory deficit is the main and usually the first symptom of AD, especially with deficiency of retention and recall of new information. The present study aims to evaluate if there are changes in oxidative metabolism detected in the blood of patients with AD, and if there is correlation with different stages of the disease and the patients’ cognitive framework. We evaluated 30 patients with Alzheimer’s disease and 28 subjects in the control group attended at Unit Education and Assistance Physical Therapy and Occupational Therapy at the University of Pará (UEAFTO-UEPA). Oxidative metabolism was assessed by measuring the total antioxidant capacity equivalent to Trolox (TEAC) and measuring the levels of substances that react with thiobarbituric acid (TBARS). Neuropsychological tests were also performed on all participants in the study. No significant correlations were observed in the performance of neuropsychological tests to the levels of TBARS and TEAC in patients with AD. It was observed that the total antioxidant capacity (TAC) was significantly decreased in AD patients compared to controls whatever stage of disease, showing a possible relationship between TAC and AD. In the evaluation of TBARS was a trend toward higher concentrations in AD patients than in control group but the difference was not statistically significant, only the moderate stage was significant when compared with the control group. Evaluation of the lipidic peroxidation through TBARS a biomarker would probably not be suitable for Alzheimer's disease.

Pulmonary involvement is one of the extra-articular manifestations of rheumatoid arthritis and can be due to the disease itself or secondary to the medications used in order to treat it. We report the case of a 60-year-old woman who had been diagnosed with rheumatoid arthritis and developed multiple pulmonary nodules during treatment with leflunomide.
