Roentgenogram

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. 

To define the incidence of fractures and rickets that we were encountering in infants who required prolonged parenteral feeding, we reviewed the roentgenograms of a series of preterm infants who developed necrotizing enterocolitis and who required at least four weeks of total parenteral nutritional support (4). These data are recorded in Table I. 

Maresh,7 in his study of the development of hearts during childhood sponsored by the Child Research Council of Denver, has made findings perfectly in accord with these given by Anson. From the study of repeated roentgenograms of 71 normal boys and 57 normal girls (3,205 roentgenograms total), Maresh concluded ... 

Composite drawing showing size and growth of the sinuses in R. Q. (actual size of the tracings from the roentgenograms at each age represented). 

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.

A 62-year-old woman was without respiratory illness until the day she cleaned with a mixture of ammonia and bleach. She noted eye, nose, and throat irritation, but continued to clean for several hours. Several hours later, she noted increasing respiratory distress and called an ambulance. Upon arrival, paramedics had to intubate her at home due to respiratory failure. The woman recovered after 30 days of hospitalization, though a roentgenogram taken 38 days after admission showed residual interstitial infiltrate. 

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. ... 

A roentgenogram of the affected part should be considered when infection is documented in proximity to a bone or joint. 

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. 

Paraclinical data. The roentgenogram shows a number of spot shades of different size in both lung sides, determining the toxic oedema and the bronchpneumonia the electrocardiogram points to miocardiac lesion.
