It has recently been demonstrated that a lateralized distractor that matches the individual's top-down control settings elicits an N2pc wave, an electrophysiological index of the focus of visual-spatial attention, indicating that contingent capture has a visual-spatial locus. Here, we investigated whether contingent capture required capacity-limited central resources by incorporating a continge...

It is widely acknowledged that visual input is processed along two anatomically and functionally distinct pathways--a ventral pathway for conscious perception and a dorsal pathway for action control. The present study investigated whether the apparent direct and unmediated processing in the dorsal stream is subject to capacity limitations. Specifically, we tested whether a simple dorsal task of...

Seizures are common consequence of traumatic brain injury (TBI) and have been reported in clinical series as an incidence of 15% to 22% in patients of traumatic brain injury. Nonconvulsive seizures (NCS) are also common that approximately 10% of patients have been suffered from electroencephalographically detected seizures during the acute period of TBI. Early posttraumatic seizures are one cau...

BACKGROUND Varicella pneumonia has been studied extensively in adults; it may also affect children and may require hospitalization. METHODS We examined pneumonia complications in children hospitalized for varicella, over a 13 year period. RESULTS Pneumonia occurred in 8.2% of children hospitalized for varicella. The median length of hospitalization was 6 days. No statistically significant d...

Results We recorded a total cost up to 660 million dollars in the whole period of study, from asthma hospitalization. The annual cost in Brazil is about 44 million dollars/ year, which represents about 164.13 dollars for each event. Duration of a hospitalization in our country means 3,2 days per event, varying from 2,7 to 4,4 days. These costs varied from USD 50,476,829 in 2000 to USD 34,369,56...

BACKGROUND Despite more than a decade of extensive, international efforts to characterize and understand the increased symptom and illness-reporting among veterans of the 1991 Gulf War, concern over possible long-term health effects related to this deployment continue. The purpose of this study was to describe the long-term hospitalization experience of the subset of U.S. Gulf War veterans stil...

OBJECTIVE To determine if psychiatric hospitalization precluded a return to occupational status in United States Air Force aviators. DESIGN A 7-yr retrospective review that joined hospitalization and occupational databases using individual identifiers. SUBJECTS From a population of over 35,000 USAF rated aviation officers present between January 1986 and December 1990, 214 were both psychia...

Radioiodine mostly 131I is one of the oldest clinical radionuclide types which used widely spread in diagnosis and currently used in the treatment of both thyreotoxicosis and thyroid cancer. This is an integral part of differentiated thyroid carcinoma therapy [1,2]. For most thyroid cancer treatments, large doses of 131I are administered to ablate residual thyroid tissue and functional metastas...

OBJECTIVE To investigate the relationship between socioeconomic factors, maternal characteristics, breastfeeding, and hospitalization for bronchiolitis in the post-neonatal period. METHODS A nested case-control study with a cohort of 5,304 children born in the city of Pelotas, Brazil, was conducted. The cohort study consisted of four sub-studies with their own methods and logistics. Mothers w...
