Abstract:
Sinusitis, which primarily involves the anterior ethmoid air cells, can spread to the larger sinus cavities to cause acute and chronic secondary infection. Endoscopic and computed tomographic techniques enable earlier diagnosis and treatment of sinusitis and permanent cure. Primary care physicians should try to identify the disease before it reaches a stage where endoscopic control becomes difficult. Ultrasonography is now used in Europe to diagnose sinusitis and initiate treatment.

Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
