BACKGROUND Anesthesia given to immature rodents causes cognitive decline, raising the possibility that the same might be true for millions of children undergoing surgical procedures under general anesthesia each year. We tested the hypothesis that anesthesia-induced cognitive decline in rats is treatable. We also tested if anesthesia-induced cognitive(More)
An extensive conceptual analysis to establish the primary role a forward head posture plays in the appearance of some craniomandibular dysfunctions and internal derangements of the temporomandibular joints, associated to craniocervical postural disturbances. The analysis is based on findings contributed by scientific investigations in the field of(More)
BACKGROUND While studying neurotoxicity in rats, we observed that the anesthetic minimum alveolar anesthetic concentration (MAC) of isoflurane decreases with increasing duration of anesthesia in 7-day-old but not in 60-day-old rats. After 15 min of anesthesia in 7-day-old rats, MAC was 3.5% compared with 1.3% at 4 h. We investigated whether kinetic or(More)
Toxoplasmic encephalitis (TE) is among the most common neurologic affections and it is the most prevalent cause of intracerebral mass lesions in AIDS patients. All patients with AIDS hospitalized at the Hospital de Clínicas de Porto Alegre between May/85 and December/91 (516 cases) had their files revised to determinate TE prevalence, serology, sensitivity(More)
A survey of reproductive tracts from nonpregnant cows at an abattoir was conducted. Reproductive tracts from 98 cows were studied microscopically and evaluated with a grading system to determine the severity of pathologic changes. Inflammatory reaction (type and distribution), fibrosis, gland morphology, and appearance were measured, quantified, and scored(More)
One hundred cases of colorectal cancer resected at the University Hospital of Caracas are presented, with emphasis in the Pathological Findings (Anatomical location and staging included). Age and sex distribution are comparable to data presented in other local series; in contrast, the proportion of rectal cancer is below expectations (only 5% of all cancer(More)
