Review Case Reports
Pneumothorax complicating small-bore feeding tube placement.
Small-bore Silastic feeding tubes are being used with increasing frequency for short- and long-term enteral hyperalimentation. We present three cases where these flexible tubes were passed into the tracheobronchial tree and then out into the pleural space. The result in each case was a pneumothorax or hydropneumothorax. ⋯ The traditional methods of assessing proper nasogastric tube placement are inadequate when applied to these small tubes. Only a chest roentgenogram can assure placement in the stomach. Education of hospital staff on methods to avoid malposition of feeding tubes has resulted in an absence of pulmonary complications over a subsequent 1-year period.

We describe a case of severe refractory hypoglycemia secondary to topical salicylate intoxication. A 72-year-old man with psoriasis and end-stage renal disease was treated with a topical cream containing 10% salicylic acid. The patient presented with encephalopathy and subsequently developed hypoglycemia refractory to infusions of large amounts of glucose. ⋯ Salicylate is well absorbed across normal and diseased skin. Salicylate markedly impairs gluconeogenesis and increases glucose utilization, resulting in hypoglycemia. To our knowledge, this is the first article on hypoglycemia due to the application of topical salicylate.
