Chronic obstructive pulmonary disease is associated with altered neuropsychological performance in young adults.

Background: Subjects with ischemic lesions have an increased risk of dementia. In addition, Alzheimer's disease (AD) and vascular cognitive impairment share many risk factors. These observations suggest that different diseases that cause altered blood perfusion of the brain or hypoxia promote AD neurodegeneration.

[Prosthesis use in pediatric patients with fibular hipoplasia].

Objective: To assess the prosthesis adaptability at use of pedestal and transtibial prosthesis, recognize the average average age of amputation surgery, and the complications of the amputation in patients with fibular hemimelia.

Material And Methods: 47 patients were evaluated, initially to adjust pedestal prosthesis and when this was not tolerated, we realize amputation and adaptation of transtibial prosthesis, we valued the average age of amputation surgery, the associate complications and the prosthesis adaptability we use the K system for functional ambulation.

Results: Of the 12 patients to actually use pedestal prosthesis 9 (75%) had a K.

[Silica in ceramic industry: exposition and pulmonary diseases].

Since 1990, a cohort survey has been carried out among workers employed in pottery workers by the Local Health Unit of Viterbo, Latium (Italy). Cumulative exposure to silica containing dust has been assessed for 808 workers, who were also screened with a questionnaire on respiratory symptoms, chest radiography and lungfunction tests.
