Objectives:
To study the management of acute maxillary sinusitis (AMS) in Finnish primary care and to compare it both to recommendations in national guidelines and to the management of other upper respiratory tract infections (URTI).
Design:
A cross-sectional multi-centre epidemiological survey.
Setting:
Thirty primary care health centres in Finland.
Subjects:
7284 patients with symptoms of possible acute rhinosinusitis during one week in both November 1998 and November 1999.
Main Outcome Measure:
Symptoms and their duration, use of diagnostic tools, choice of antibiotics, patient outcomes.
Results:
A total of 1601 patients were diagnosed as having AMS (12% of all patients with infectious disease). In 45% of cases the differentiation between AMS and URTI was based on clinical examination alone. Sinus ultrasound was the most common diagnostic tool used (38%). Sinus radiography or blood tests (CRP or leukocytes) were both studied in 8% of cases. AMS was diagnosed and treated with antibiotics also in the early stages of URTI when viruses are the most likely explanation. In total, 83% of patients with AMS received a prescription for antibiotics; the most common choice was amoxycillin (37%), doxycycline was used in 29% of cases, and macrolides in 15%.
Conclusions:
Antibiotics are prescribed for AMS 2 to 5 times more often than true disease incidence would suggest in Finland. The choice of antibiotics follows the guideline recommendations; however, use of macrolides is higher than recommended. Physicians feel strong pressure from patients to prescribe antibiotics for AMS. Primary care physicians need better support in the accurate diagnosis of AMS.

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
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...
01:20Sputum 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,...
