Roentgenogram chest

Respiratory alkalosis secondary to hyperventilation is usually observed secondary to CNS stimulation of ventilatory centers as a result of trauma, sepsis, or shock. Lung auscultation may reveal crackles (pulmonary edema) or absence of breath sounds (pneumothorax, hemothorax). Chest roentgenogram can confirm early suspicions or disclose an undetected abnormality such as pneumonia (pulmonary infiltrates). Continued insult to the lungs may result in adult respiratory distress syndrome. 

Seventeen people exposed to phosphorus trichloride liquid and its hydration products after a tanker accident were evaluated. Those closest to the spill experienced burning of the eyes, lacrimation, nausea, vomiting, dyspnea, and cough. Six patients had transient elevation of lactic dehydrogenase. Chest roentgenograms were normal. Pulmonary function tests showed statistically significant decreases in vital capacity and FEVi in direct correlation with distance from the accident and duration of exposure. Of the 17 patients examined 1 month later, pulmonary function tests showed improvement, suggesting that acute effects were due to phosphorus trichloride toxicity. ... 

Cohort and case control analyses of 1576 workers found no statistically significant associations between titanium dioxide exposure and risk of lung cancer, chronic respiratory disease, and chest roentgenogram abnormalities. No cases of pulmonary fibrosis were observed among titanium dioxide-exposed employees. 

Physical examination, routine laboratory tests, and chest roentgenogram were unremarkable. Testicular function as evaluated clinically and by the measurement of serum androgens, FSH, LH, and sperm count were normal in all patients. Zinc status as assessed by the determination of zinc concentration in plasma, erythrocytes, and hair was within normal limits. 

Cor pulmonale usually is not evident clinically unless signs of leftsided heart failure ensue, although enlargement in cardiac size may be noted on routine chest roentgenogram prior to that time. Signs and symptoms of anemia and arthritis in CF patients do not differ from those owing to other chronic diseases. 

NSAIDs also have been associated with pulmonary infiltrates and eosinophilia (PIE) syndrome. This syndrome is associated with fever, cough, dyspnea, infiltrates on chest roentgenogram, and a peripheral eosinophilia that develop 2 to 6 weeks after initiating treatment. PIE syndrome occurs more frequently for naproxen compared with other NSAIDs and is noted to resolve rapidly after discontinuation of the offending agent. ... 

Adult patients with AIDS demonstrate an acute form of disseminated disease that resembles the syndrome seen in infants and children. Progressive disseminated histoplasmosis (PDH) can occur as the direct result of initial infection or because of the reactivation of dormant foci. In endemic areas, 50% of AIDS patients demonstrate PDH as the first manifestation of their disease. Progressive disseminated histoplasmosis is characterized by fever (75% of patients), weight loss, chills, night sweats, enlargement of the spleen, liver, or lymph nodes, and anemia. Pulmonary symptoms occur in only one-third of patients and do not always correlate with the presence of infiltrates on chest roentgenogram. A clinical syndrome resembling septicemia is seen in approximately 25% to 50% of patients.

C) A physical examination directed to the pulmonary and gastrointestinal systems, including a chest roentgenogram to be administered at the discretion of the physician, and pulmonary function tests of forced vital capacity (FVC) and forced expiratory volume at one second (FEV(1)). Interpretation and classification of chest shall be conducted in accordance with Appendix E to this section.
