Objectives:
Conservative treatments are usually the preferred choices for newly diagnosed adult otitis media with effusion (OME). This study was performed to explore the efficacy of conservative treatments, including medication and eustachian tube auto-inflation (ETA), for treating OME in adults and to analyze its predictors.
Materials And Methods:
A total of 107 adult patients with OME were included. All patients completed two weeks of conservative treatments including medication alone or the combination of medication and ETA.
Results:
The numbers of patients with only one and both ears affected were 79 and 28, respectively, and therefore, 135 affected ears were included. After treatment, 75 affected ears were classified as responders (55.6%), while 60 ears were classified as nonresponders (44.4%). Four predictive factors, including age, air-bone gap (ABG), tubomanometry value (TMM), and the treatment plan (all p<0.05) were found in treatment outcomes. Patients with age ≤50 years (vs. age>50 years), ABG <17 dB (vs. ABG≥17dB), TMM values of 2-6 (vs. TMM values of 0-1), and patients who received combined treatments, including medication and ETA (vs. patients who received medication only), were more likely to be responders (all p<0.05).
Conclusion:
For OME in adult patients, younger age, smaller ABG, higher TMM value, and combined treatment including medication and ETA are good predictors for treatment success.

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.

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...
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,...
01:11Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
