Abstract:
461 chromium- and nickel-exposed steelworkers were otolaryngologically examined by endoscopy. Besides chronic inflammatory diseases of the ear, nose and paranasal sinuses, the clinical diagnosis of leukoplakia and hyperplastic laryngitis was made for 30 workers. In no case a lesion suspicious of cancer was found. Office staff showing no such occupational risk factors served as the control group. It was found that in both groups smoking has to be assumed as the decisive factor for the development of chronic inflammation and precancerous changes in the oral cavity and the larynx.

Endoscopic Studies I: Bronchoscopy and Thoracoscopy
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
Endoscopic Studies II: Thoracocentesis
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...
