ABC's of Trauma :economic of chest radiograph

The chest radiograph is an economical and sensitive screening examination for the major injuries in the patient who has sustained blunt chest trauma. Just as the physician uses the ABC's to stabilize the critical ill patient (Airway, Breathing, Circulation), the radiologic ABC's prompt the radiologist to consider all of the critical injuries that may be sustained with blunt trauma. THE most critical injury is considered first.

  • Aortic Transection
  • Bronchial fracture
  • Cord injury (Thoracic spine)
  • Diaphragmatic rupture
  • Esophageal tear
  • Flail chest
  • Gas (subtle pneumothorax)
  • Heart (Cardiac injury)
  • Iatrogenic (Misplaced monitoring & support catheters)

Effects of Some drugs on teeth

Hypertrophied gums are most likely the result of which of the following?

  • a.Hutchinson’s teeth
  • b.Tetracycline administration
  • c.Administration of diphenylhydantoin
  • d.Overdose of fluoride
  • e.Lead poisoning
  • f.Bulimia

The answer is ( C ).
Use of the anticonvulsant diphenylhydantoin, or of the calcium channel blocker nifedipine, may cause fibrous hyperplasia of the gingiva, leading to hypertrophied gums.

Tetracycline given to children or pregnant women causes
enamel hypoplasia and discoloration of the teeth. Ingestion of large amounts of fluoride may cause mottling of the tooth enamel. Lead poisoning causes the formation of a black “lead line” in the gums.
Hutchinson’s teeth are the congenital notched teeth of syphilis. Bulimia causes erosion of
the enamel on the surfaces of the teeth due to frequent gastric acid exposure.
