Managing sore throat: a literature review. II. Do antibiotics confer benefit?
1Department of Social and Preventive Medicine, University of Queensland, Medical School, Herston.
Objective:
To assess the justification for the use of antibiotics in the management of sore throat in general practice.
Data Sources:
The literature from 1945 to 1990 was systematically screened to identify studies that addressed the question whether antibiotics reduce non-suppurative and suppurative complications and symptoms of sore throat. The key-words, "pharyngitis" and "tonsillitis" were used to identify trials of antibiotics for the treatment of sore throat.
Study Selection:
Studies were included in comparison tables if they involved the trial of one or more antibiotics against a control and there was an outcome in terms of reduction in the incidence of acute rheumatic fever, acute glomerulonephritis, acute otitis media, acute sinusitis, quinsy or any symptoms related to the acute illness.
Results:
The published literature suggests that antibiotic treatment protects patients with sore throat against acute rheumatic fever and some suppurative complications, but not against acute glomerulonephritis. It does not reduce the symptoms.
Conclusions:
In Australia, with the exception of socioeconomically deprived Aboriginal communities, the incidence of acute rheumatic fever is probably not high enough to justify the use of antibiotics for sore throat. Protection against suppurative infection seems to be slight and it is difficult to establish the benefit of antibiotic treatment for reducing the symptoms of sore throat. Until more benefits for antibiotic management of sore throat can be demonstrated, it is recommended that infrequent use be adopted.

01:30Acute 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:
01:23Chronic 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,...

Etiology

Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
01:28Pleural Effusion II: Symptoms and Management
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
