Otitis media with effusion was common in Thai children with cleft palate. Surveillance of middle ear effusion and ventilation tube insertion contributed to a favorable hearing outcome.
Background: Nasal obstruction is often impact on quality of life in allergic rhinitis (AR). The steam inhalation is one of widely used home remedies to soothe and open the nasal passages. Furthermore, steam inhalation may provide change in objective nasal airway assessment.Objectives: To compare the effect of steam inhalation on nasal obstruction between patients with AR and normal individuals, as well as the change in the cross-sectional area of the nasal cavity and in nasal airway resistance (NAR) between 2 groups.Method: A prospective comparative, parallel group study was conducted in AR and normal individuals. Steam with the temperature of 42-44°C was inhaled. Variables obtained before and after steam inhalation were compared.Results: After steam inhalation, nasal symptom score, combined global symptoms, and Visual Analog scale (VAS) of combined global symptoms of AR patients showed statistically significant improvement. Whereas, normal individuals, there was statistically significant improvement only in sneezing and combined global symptoms. Meanwhile, the change of each measurement score, combined global symptoms, and VAS of the symptoms in those with AR were significantly higher than those of normal individuals. Total nasal airflow, NAR, volume, and mean minimal cross-sectional area of AR patients tended to better improve after steam inhalation. Conclusion:The steam inhalation significantly improved nasal obstruction in AR patients, but no statistical significant difference between both groups for any parameters. The different response between the 2 groups may be due to different nasal mucosa sensitivity to stimuli.
Objective To assess the accuracy and clinical reliability of watch peripheral arterial tonometry (PAT) compared with polysomnography (PSG) for the diagnosis of pediatric obstructive sleep apnea (OSA). Study Design Prospective, diagnostic test study. Setting National tertiary referral hospital. Subjects and Methods Patients aged 8 to 15 years with clinically suspected OSA were recruited. All participants underwent PSG and PAT simultaneously in the sleep laboratory. Results Thirty-six patients were included, with a mean age of 10.2 ± 1.8 years. Median (interquartile range) of the apnea hypopnea index (AHI) was 8.0 (5.5-12) and 2.9 (0.5-7.5) events/h, median oxygen desaturation index (ODI) was 2.5 (1.4-8.3) and 1.3 (0.2-3.8) events/h, mean ± standard deviation total sleep time was 398.4 ± 38.3 and 401.9 ± 36.1 minutes, and mean minimum oxygen saturation was 87.1% ± 8.1% and 89.4% ± 7.1% for PSG and PAT sleep parameter results, respectively. Agreement between methods was excellent for the AHI (intraclass correlation coefficient [ICC]: 0.89; 95% CI, 0.40-0.96; P < .001) and ODI (ICC: 0.87; 95% CI, 0.69-0.94; P < .001). Correlation between methods was very good for the ODI ( r = 0.83; 95% CI, 0.67-0.90; P < .001) and moderate for the AHI ( r = 0.64; 95% CI, 0.30-0.85; P < .001). From the receiver operating characteristic curve constructed to assess PAT diagnostic capability, AHI of PAT (W-AHI) at a cutoff of 3.5 events/h provided the highest accuracy (76.9% sensitivity, 78.3% specificity), while W-AHI at 10 events/h yielded 91.3% specificity for diagnosing severe OSA. Conclusion PAT correlated well and had good agreement with PSG. Children with W-AHI ≥10 had high specificity for the diagnosis of severe OSA. Larger studies with PAT designed for children across all age ranges and with a normal control group are still needed.
