Ear, nose and throat diseases in Saudi Arabia. Microbiology and clinical observations
Abstract:
Clinical specimens from 243 patients attending the ENT clinics at King Abdul Aziz University Hospital, Riyadh, Saudi Arabia were investigated for the pathogens attributing to otitis media and tonsillitis. In children as well as in adults with otitis media, the main bacterial causative organisms were Staph, aureus and Ps. aeruginosa; Asp. flavus was detected in 1% and 4% of adult and children cases of otitis media. In tonsillitis H. influenzae, Strept. pneumoniae, Staph. aureus, Strept. gr. A were isolated in only 18% of the children and Strept. pneumoniae, Strept. gr A in 16% of adults. A possible involvement of viruses in tonsillitis is indicated.

Physical Assessment of the Respiratory Tract I: Health History
Subjective Data
Subjective data provides vital information about the patient's health history and symptoms. This data is typically collected through interviews in which patients describe their experiences, symptoms, and concerns.

Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

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,...
