Asia-Pacific survey of physicians' perceptions and managements of chronic rhinosinusitis.

BACKGROUND: The diagnosis and management of patients with chronic rhinosinusitis (CRS) may vary between otolaryngologists and allergists. Moreover, the adherence of different practitioners to European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) 2020 guideline recommendations has not been previously ascertained in Asia-Pacific regions. OBJECTIVE: Different specialists' perceptions and managements of CRS in Asia-Pacific regions were assessed in an attempt to gauge these practices against EPOS 2020 guidelines. METHODS: A transregional, cross-sectional survey was conducted to assess otolaryngologists' and allergists' perceptions and managements of CRS with regard to diagnosis, management and adherence to EPOS 2020 guidelines. RESULTS: Sixteen physicians in Asia-Pacific regions responded to the questionnaire. A total of 71.4% of otolaryngologists preferred to diagnose CRS with a combination of positive nasal symptoms and nasal endoscopy plus sinus CT, whereas 22.2% of allergists took such criterion to diagnose CRS. Compared to allergists, otolaryngologists more often considered the endotype classification (85.8% versus 55.5%). For the preferred first-line treatment, in addition to intranasal corticosteroids recommended by all respondents, 66.7% of allergists preferred antihistamines, whereas 71.4% of otolaryngologists preferred nasal saline irrigation. Regarding the proper timing of surgery, 71.5% of otolaryngologists reported 8-12 weeks of treatment after the initiation of medication, while more than half of the allergists recommended 4-6 weeks of medical treatment. CONCLUSIONS: This survey shows that variable perceptions and practices for CRS may exist between physicians with different specialties and highlights the need for increased communication and awareness between otolaryngologists and allergists to improve the diagnosis and treatment of CRS.

Long Versus Short-segment Stabilization in Patients with Traumatic Thoracolumbar Fractures.

BACKGROUND: Posterior stabilization surgery is considered the gold standard for restoring spine stability in patients with traumatic thoracolumbar fractures. However, whether long-segment (LS) stabilization or short-segment (SS) stabilization is an optimal approach for achieving more effective restoration of spinal stability remains unclear. MATERIAL AND METHODS: Patients who underwent posterior stabilization surgery for traumatic thoracolumbar fractures were included in the study. Radiological parameters were measured using pre- and post-surgical thoracolumbar computed tomography (CT) scans and compared between patients who received LS and SS stabilization. RESULTS: Ninety-eight consecutive patients (mean age 4414, 50% male) who underwent posterior stabilization surgery for traumatic thoracolumbar fractures were included. LS stabilization was performed in 52 patients, while SS stabilization was performed in 46 patients. Among spinal stability parameters measured on pre-surgical thoracolumbar CT scans, the anterior vertebral height (AVH) was significantly lower in the LS stabilization group compared to the SS stabilization group (14.44.0 mm vs. 16.44.0 mm, p=0.017), indicating a more severe compression fracture in the LS stabilization group. However, all parameters improved on post-surgical thoracolumbar CT scans, and there were no significant differences between LS stabilization and SS stabilization groups in terms of the restoration of spinal stability parameters. The type of stabilization (LS vs. SS stabilization) did not show an association with post-surgical measurements of spinal stability parameters (B=0.27, 95% CI -1.87 to 2.42, p=0.800 for superior inferior end plate angle (SIEA), B=0.20, 95% CI -1.33 to 1.74, p=0.796 for AVH, and B=0.39, 95% CI -1.72 to 2.50, p=0.714 for Cobb angle). CONCLUSIONS: Both LS and SS stabilization approaches yield similar results in terms of restoring spine stability parameters in patients with traumatic thoracolumbar fractures. The choice of surgical approach should be individualized based on the patient's overall status and the surgeon's experience.

Survey of non-prescribed use of antibiotics for children in an urban community in Mongolia.

OBJECTIVE: to estimate the prevalence and identify the determinants of non-prescription use of antibiotics for children in Mongolia. METHODS: a community-based cross-sectional survey was undertaken in 10 subdistricts in Ulaanbaatar, Mongolia's capital. We used a structured questionnaire to collect data from a random sample of 540 households with at least one child aged < 5 years. Logistic regression was used to identify factors associated with antibiotic misuse. FINDINGS: of 503 participating caregivers, 71% were mothers; 42.3% (95% confidence interval, CI: 37.8-46.9) of caregivers had used non-prescribed antibiotics to treat symptoms in their child during the previous 6 months. Symptoms commonly treated were cough (84%), fever (66%), nasal discharge (65%) and sore throat (60%). Amoxicillin was the most commonly used antibiotic (58%). Pharmacies were the main source (86%) of non-prescribed antibiotics. Non-prescribed use by mothers was significantly associated with keeping antibiotics at home (odds ratio, OR: 1.7; 95% CI: 1.04-2.79), caregiver self-medication (OR: 6.3; 95% CI: 3.8-10.5) and older child's age (OR: 1.02; 95% CI: 1.01-1.04). Caregivers with a better knowledge of antibiotics were less likely to give children non-prescribed antibiotics (OR: 0.7; 95% CI: 0.6-0.8). CONCLUSION: the prevalence of non-prescribed antibiotic use for young children was high in Ulaanbaatar. Because such use leads to the spread of bacterial resistance to antibiotics and related health problems, our findings have important implications for public education and the enforcement of regulations regarding the sale of antibiotics in Mongolia.

Asia Pacific Association of Allergy Asthma and Clinical Immunology White Paper 2020 on climate change, air pollution, and biodiversity in Asia-Pacific and impact on allergic diseases

Air pollution, climate change, and reduced biodiversity are major threats to human health with detrimental effects on a variety of chronic noncommunicable diseases in particular respiratory and cardiovascular diseases. The extent of air pollution both outdoor and indoor air pollution and climate change including global warming is increasing-to alarming proportions particularly in the developing world especially rapidly industrializing countries worldwide. In recent years, Asia has experienced rapid economic growth and a deteriorating environment and increase in allergic diseases to epidemic proportions. Air pollutant levels in many Asian countries especially in China and India are substantially higher than are those in developed countries. Moreover, industrial, traffic-related, and household biomass combustion, indoor pollutants from chemicals and tobacco are major sources of air pollutants, with increasing burden on respiratory allergies. Here we highlight the major components of outdoor and indoor air pollutants and their impacts on respiratory allergies associated with asthma and allergic rhinitis in the Asia-Pacific region. With Asia-Pacific comprising more than half of the world's population there is an urgent need to increase public awareness, highlight targets for interventions, public advocacy and a call to action to policy makers to implement policy changes towards reducing air pollution with interventions at a population-based level.

Prevalence of asthma and allergic rhinitis among adult population in Ulaanbaatar, Mongolia.

BACKGROUND: Mongolia is changing lifestyle, unhealthy habits, increase of air pollution, increasing life expectancy have led to an up rise of chronic respiratory diseases. Over 10 years ago, the prevalence of asthma and allergic rhinoconjunctivitis in Mongolia were in the lower range reported from previous studies. OBJECTIVE: The main aim of the survey is to know the prevalence of asthma and allergic rhinitis among adult population of Ulaanbaatar city, Mongolia and their risk factors. METHODS: Total of approximately 1,200 adults aged 20 years and over were planned to be randomly selected. The questionnaire was developed on the basis of WHO Protocol for Assessment of Prevalence of Major Respiratory Diseases and modified by local risk factors assessment and by other international survey approach including Global Initiative for Asthma and European Community Respiratory Health Survey. RESULTS: Prevalence of current wheezer in all age group was 15.7% (95% CI: 14.7-16.8). Age and sex segregated distribution of current wheezer were defined among male and female and prevalence was 14.5% (95% CI: 13.3-16.2) in male and female 16.6% (95% CI: 15.2-18.3) respectively. Prevalence of diagnosed asthma among adults was 4.7% (95% CI: 4.3-5.6) in all age group, 3% (95% CI: 2.4-3.7) in male and 6.8% (95% CI: 5.8-7.9) in female. Prevalence of rhinoconjunctivitis was 14.6% in all age group. 28.4% out of subjects with allergic rhinitis has current asthma, while 11.6% of subjects without allergic rhinitis has asthma (p < 0.01). CONCLUSION: The prevalence of asthma increased for one decade in Ulaanbaatar. Prevalence of diagnosed asthma is approximately 5% and current wheezer is approximately 15% in adults of population, which is close to other Asia and European countries. Allergic rhinitis is a risk factor for asthma.
