BACKGROUND |
From the beginning of the influenza pandemic until the time the outbreak described here was detected, 77,201 cases of pandemic influenza A(H1N1) with 332 deaths had been reported worldwide, mostly in the United States and Mexico. All of the cases reported in Spain until then had a recent history of travel to Mexico, th... |
METHODS |
We collected diagnostic samples and clinical histories from consenting medical students who had traveled to the Dominican Republic and from their household contacts after their return to Spain. |
RESULTS |
Of 113 students on the trip, 62 (55%) developed symptoms; 39 (45%) of 86 students tested had laboratory evidence of influenza A(H1N1) infection. Most students developed symptoms either just before departure from the Dominican Republic or within days of returning to Spain. The estimated secondary attack rate of influenz... |
CONCLUSIONS |
The attack rate of influenza A(H1N1) can vary widely depending on the circumstances of exposure. We report a high attack rate among a group of traveling medical students but a much lower secondary attack rate among their contacts after return from the trip. These findings may aid the development of recommendations to p... |

OBJECTIVE |
To evaluate the diagnostic accordance between scintigraphy and radiography in the early period following blunt thoracic trauma. |
DESIGN |
Double-blind, prospective clinical study. |
METHODS |
Thirty-four adult patients with blunt thoracic trauma were examined by plain radiography and scintigraphy within 24 hours of trauma. |
RESULTS |
Radiography displayed pathologies in 25 (73.5%), while scintigraphy suggested pathologies in 24 (70.5%) patients. Rib fractures were identified radiographically in 16 (47%) and scintigraphically in 17 (50%) patients. Lateral radiograph of the sternum showed fracture in 10 (52.6%), while scintigraphy suggested fracture ... |
CONCLUSION |
Scintigraphy gave better results in the evaluation of sternal fractures during the early period of thorax trauma. Conventional plain radiography is thought to be the initial imaging modality, because it saves time and shows hemothorax or pneumothorax besides the osseous abnormality.Temperature dependence of light-outpu... |
