Background: Abdominal aortic aneurysms (AAAs) are the most common. The annual incidence of AAA rupture is eight cases per 100,000 inhabitants. Incidental detection can benefit patients if diameter is monitored and the correct treatment provided. Objectives: To estimate the prevalence of incidental diagnosis of thoracic aortic aneurysm (TAA) and AAA by computed tomography (CT); to determine prevalence by age and sex of patients and determine which arteries are involved and the morphological characteristics of the aneurysms; to determine the indications for CT most associated with incidental diagnosis of aneurysms. Methods: This was a descriptive, retrospective and randomized study. Inclusion criteria: patients over 50 years of age examined with CT of the thorax, abdomen or pelvis. Exclusion criteria: follow-up or diagnostic suspicion of aneurysms. Data collection instruments containing questions covering demographic and anatomic data were used. Results: A sample of 1,202 radiology reports was reviewed. A total of 27 aneurysms were detected (prevalence of 2.2%). Patients: 60% were male and 40% were female (p < 0.05). Sites: there were 13 cases (48.2%) in the ascending aorta (TAA); 7 (25.9%) in the infrarenal aorta (AAA); 2 (7.4%) at the thoracoabdominal transition of the aorta (TTA); 2 (7.4%) in the common iliac artery ; 1 (3.7%) in the internal iliac artery; 1 (3.7%) in the splenic artery; and 1 (3.7%) in the renal artery. Conclusions: The majority of patients were male (60%); TAA was the most common type (mean diameter: 4.1 cm), followed by AAA (mean diameter: 4.0 cm) and ATA (mean diameter: 3.9 cm). The most common indication for the CT examination that led to incidental diagnosis of an aneurysm was respiratory symptoms.

Variação sazonal da população de bactérias e fungos e dos teores de nitrato e amônio do solo nos sítios do LBA e PPBIO, na amazônia oriental

It is possible that the environmental factors determining the behavior of soil microbiota are being modified by anthropic or natural climate change. In order to check the effect of the exclusion of water over the population of bacteria and fungi in the soil, the present study was developed. The chosen location is the area of the ESECAFLOR experiment, which simulates the occurrence of extreme phenomena such as El Niño event, and the area of biodiversity research program Program-PPBio (primary forest). This later area, supposed to be used for studying the Biodiversity of the Amazon, was used as a control area for comparative purposes. The soil was sampled at 00 - 05, 05 -10, 10-20 and 20-30 cm depths, during the rainy, transition and less rainy seasons. The highest values of Colonies Forming Units (CFU) for bacteria and fungi populations were 196 x 104 CFU/g of soil and 124 x 102 CFU/g of solo, respectively, both in the area without human intervention (PPBio). Soil moisture is the variable influencing most the obtained counting values of fungi and bacteria populations.
