Our study was performed in 33 nonconsecutive patients (17 men and 16 women; mean age, 57 ± 14 years) who were admitted to our ICU with a diagnosis of pulmonary embolism. In 21 of them (64 percent), the diagnosis of pulmonary embolism was initially made on the basis of the presence of multiple, large segmental [...]

Perfusion lung scintigraphy is probably the most reliable noninvasive tool to evaluate restoration of pulmonary blood flow after pulmonary embolism. In spite of that, its use is often limited to the acute phase of pulmonary embolism. Since abnormalities of the arterial blood gases and expired air composition are the most important functional consequences following acute [...]

Thoracic oudet syndrome denotes compression of the brachial plexus, the subclavian vessels, or both, accompanied by paresthesia, pain, numbness, and fatigue in the affected extremity. The chief contributing factors are bone abnormalities (fractured clavicle, cervical rib, or hypoplastic first rib), which are present in 30 percent of the cases;* in fact, the first rib is [...]
Thoracic oudet syndrome was described over a century ago but was given its present name by Rob and Standeven1 in 1958. Until recendy, it has been poorly understood, and many sufferers have been told by their physician that their complaints were imaginary. The syndrome can be related to numerous etiologic factors, all of which produce [...]
Nitrogen dioxide and other nitrous oxides are rapidly generated when nitric acid comes in contact with air or organic materials. After inhalation, structural lung injury becomes manifest mainly in the distal bronchioles and adjacent alveoli. This localization may reflect greater cellular solubilization of NO* at these levels than at more proximal levels and/or the airflow dynamics. The [...]
Nitric acid is commonly used in various industries. Its accidental spillage generates oxides of nitrogen, including N20, a potent pneumotoxin when inhaled. While the clinical presentation varies, a familiar feature is a period of relative well-being lasting a few hours, followed by rapidly progressive and often fatal, noncardiogenic pulmonary edema. Although its pathogenesis is not [...]
Intercountry comparability is better for mortality in the 9th revision of the ICD than in the 8th revision. Unfortunately, only a few years of time trend data are available to date and it will be necessary to continue this observation during a longer period. Results of the present analysis suggest that it is necessary to [...]
