Perfusão cerebral e análise individual automatizada utilizando SPECT em uma população com transtorno obsessivo-compulsivo

Objective: To make individual assessments using automated quantification methodology in order to screen for perfusion abnormalities in cerebral SPECT examinations among a sample of subjects with OCD. Methods: Statistical parametric mapping (SPM) was used to compare 26 brain SPECT images from patients with OCD individually with an image bank of 32 normal subjects, using the statistical threshold of p < 0.05 (corrected for multiple comparisons at the level of individual voxels or clusters). The maps were analyzed, and regions presenting voxels that remained above this threshold were sought. results: Six patients from a sample of 26 OCD images showed abnormalities at cluster or voxel level, considering the criteria described above, which represented 23.07%. However, seven images from the normal group of 32 were also indicated as cases of perfusional abnormality, representing 21.8% of the sample. Conclusion: The automated quantification method was not considered to be a useful tool for clinical practice, for analyses complementary to visual inspection.

Fatores de risco da transmissão de zoonoses por costumes da população de Ilha Solteira, Brasil

Objective Determining conditions regarding possible zoonosis transmission risk based on Ilha Solteira-São Paulo citizens' habits aimed at establishing concrete recommendations for the corresponding local authorities to reduce some risk factors. Methods100 focalized interviews were held on Ilha Solteira's urban perimeter during April 2008. The people interviewed were adults who lived or worked in houses in the study area. Results This research found a significant number of cat and/or dog owners who allowed their pets to stay in internal areas of their houses. They did not define a specific place for animals to defecate and/or urinate or did not arrange appropriate final disposal of such waste. Conclusion Local authorities must make greater efforts at educating Ilha Solteira pets' owners and providing them with information and encouraging greater citizen commitment and awareness to improve habits related to caring for pets/animal sand reducing zoonosis transmission risk factors.
