Occupational respiratory diseases have been reported following exposure to metal working fluids. We report a spectrum of respiratory illnesses occurring in an outbreak in 30 workers of an automobile parts engine manufacturing plant. Workers presented with respiratory complaints and, after clinical and laboratory evaluations, were classified as those having hypersensitivity pneumonitis, occupational asthma, or industrial bronchitis, or those without occupational lung disease. Hypersensitivity pneumonitis affected seven workers, with six exhibiting serum precipitins to Acinetobacter Iwoffii. Occupational asthma and industrial bronchitis affected 12 and six workers, respectively. Oil-mist exposures were below current recommendations. Gram-negative bacteria, but no fungi, Thermophiles, or Legionella, were identified. Although specific agents responsible for each individual case could not be identified, probably both specific sensitizing agents and non-specific irritants from metal working fluids, additives, or contaminants contributed to this spectrum of occupational respiratory illness.

Any child presenting with a voice disturbance with or without stridor is recommended to have diagnostic flexible fiber-optic laryngoscopy. Recurrent respiratory papillomatosis should be considered in children when other common pediatric airway diseases either do not follow the natural history or do not respond to treatment of the common disorder.

Sinusitis remains one of the most prevalent but clinically challenging disease processes in pediatrics. Lack of appropriate culture evidence makes the diagnosis difficult, and increasing microbial resistance presents a therapeutic dilemma. This article examines causative factors, appropriate diagnostic measures, and effective medical and surgical treatment options for sinusitis in the pediatric population.
