Abstract Twenty new cases of Silo filler's disease (SFD) have been collected, documenting the incidence and clinical features of exposure to nitrogen oxides present in freshly filled silos. [ncbi.nlm.nih.gov]

Patients with acute hypersensitivity pneumonitis may present with a similar onset of acute shortness of breath, fever and lung infiltrates as silo-filler's disease. [nasdonline.org]

  Impaired breathing also occurs as was measured by Scott and Hunt [12]. Sudden death has been reported due to exposure at extremely high concentrations of gas. [oatext.com]

• Sudden Infant Death Syndrome

  It also worsens pre-existing lung diseases like asthma and has been implicated in sudden infant death syndrome (SIDS / cot death). The effects of nitrogen dioxide is compounded among silo workers because of repeated exposure. [healthhype.com]

  Approximately 8 hours later, he developed significant dyspnea, productive cough with dark sputum, fever, and malaise. The cough became dry subsequently. [shmabstracts.com]

  The most common presenting feature was dyspnea. All victims entered a silo during the peak danger period, and only one used recommended ventilation techniques. Four cases ended in death (20% mortality). [ncbi.nlm.nih.gov]

  Symptoms of silo filler’s disease include coughing, burning, shortness of breath, chills, fever, headache, nausea and vomiting. [farmsafevt.wordpress.com]

  Initial nausea, cough and fever remitted, but respiratory failure developed 3 weeks later. Roentgenograms and lung function studies revealed pulmonary in the adult edema, volume restriction, and severely impaired gas exchange. [karger.com]

  Symptoms of exposure to silo gas include coughing, burning, chills, fever and nausea. A farmer may also be exposed to silo gas, experience very mild or no symptoms and die while sleeping from fluid accumulation in the lungs. [canr.msu.edu]

• Headache

  In addition to the potential for exposure to fatal asphyxia secondary to NO2 and other oxides of nitrogen, less severe exposure to nitrogen oxides produces transient pulmonary decompensation, cough, dyspnea, and headaches. [progressivegardening.com]
