Review
INTRODUCTION
Intranasal corticosteroids (INCs) are the first line of therapy for chronic sinonasal conditions such as rhinitis and rhinosinusitis. Among these, one of the most frequently used is beclomethasone dipropionate (BDP). Over the years many studies have evaluated the efficacy of BDP as part of therapy for chronic rhinosinusitis (CRS) and allergic rhinitis (AR) along with nasal washes, which seems to be very well tolerated.
OBJECTIVE
To analyse the data in the literature regarding the various therapeutic regimens of BDP in different sinonasal disease and their efficacy and tolerability.
MATERIALS AND METHODS
Using different search engines, the posology, efficacy, and tolerability of BDP were reviewed and a total of 64 full-length articles were examined for eligibility. After applying inclusion and exclusion criteria, 4 articles were reviewed.
RESULTS
BDP is among the group of INCs with significant improvement of nasal symptoms and has good efficacy and safety.
CONCLUSIONS
BDP nasal spray is one of the most frequently prescribed INC for rhinitis and rhinosinusitis. Treatment with BDP resulted in significant and clinically meaningful improvements in nasal symptoms associated with AR and CRS. BDP is well tolerated, and the safety profile is similar to that of placebo in most patients. These results, in conjunction with the significant benefit reported in subjects with CRS and AR, provide convincing evidence of the overall effectiveness of BDP for the treatment of the full spectrum of sinonasal disease.

Meta-Analysis
OBJECTIVE
The purpose of this study was to provide evidence for early life care by meta-analyzing the relationship between infection during pregnancy and up to 2 years of age and the risk of subsequent allergic rhinitis (AR).
METHODS
Published studies up to April 2022 were systematically searched in PubMed, Embase, Web of Science, Cochrane Library, SinoMed, CNKI, Wanfang Database, and VIP. Literature screening, including quality assessment, was performed, and the effect values (OR, HR, RR) and 95% confidence intervals (95% CI) of infection during pregnancy and up to 2 years of age and allergic rhinitis were extracted from each qualified study.
RESULTS
In total, 5 studies with a sample size of 82,256 reported the relationship between infection during pregnancy and offspring AR. Meta-analysis showed that maternal infection during pregnancy was associated with an increased risk of childhood AR in offspring (OR = 1.34, 95% CI: 1.08-1.67). Altogether, 13 studies with a sample size of 78,426 reported evidence of an association between infection within 2 years of age and subsequent AR in children. A pooled meta-analysis of all studies showed that early infection within 2 years of age was closely associated with childhood AR (OR = 1.25, 95% CI: 1.12-1.40), especially upper respiratory tract infection (OR = 1.32, 95% CI: 1.06-1.65) and gastrointestinal infections (OR = 1.37, 95% CI: 1.01-1.86), but ear infection showed similar results in the cohort study (OR = 1.13, 95% CI: 1.04-1.22).
CONCLUSION
Current evidence suggests that infection during pregnancy, early upper respiratory infection, gastrointestinal infections and ear infection within 2 years of age would increase the risk of AR in children. Therefore, the prevention of infection during pregnancy and in infancy and young children needs to be emphasized.

Review
Eosinophilic esophagitis is a chronic antigen-mediated esophageal disease characterized clinically by symptoms related to esophageal dysfunction and histologically by TH2 inflammation (at least 15 eosinophils/high power field) when other secondary systemic and local causes of esophageal eosinophilia are excluded. Although this disease was initially ascribed to a delayed reaction to food allergens, emerging evidence suggests that aeroallergens may also play a role in pathogenesis and disease course. Some studies support seasonal variations in the diagnosis of eosinophilic esophagitis and disease exacerbations owing to the increase in aeroallergens to which patients are sensitized. It is also known that this disease can be caused by extensive, identifiable exposure to aeroallergens and after treatment with specific immunotherapy based on food or aeroallergens. It was recently postulated that treatment of allergic rhinoconjunctivitis can improve the symptoms of eosinophilic esophagitis, although data are limited to case reports and small series. Currently, biomarkers and biologic therapies are not helpful for diagnosis or inducing clinical and histological remission of the disease. Nevertheless, there are high hopes for dupilumab. This review aims to give visibility to the involvement of aeroallergens in the triggering and exacerbation of eosinophilic esophagitis, since many of them, in addition to being airborne and inhalant, can also be ingested as food. Clearly, we must try to identify the cause of the disease to ensure remission.

Review
OBJECTIVES
To conduct a systematic review and meta-analysis of available studies regarding the effects of the traditional herb (as topical application and oral intake) on the severity of acute pain in adults.
METHODS
A systematic search was performed on the following databases: Cochrane Central Register of Controlled Trials, PubMed, Scopus, Web of Science Core Collection, Embase, Cumulative Index to Nursing and Allied Health Literature, Scientific Information Database, and Magiran from inception to 20 March 2021. We included parallel-group and cross-over randomized controlled trials that compared the effects of any products containing in oral and topical administration forms to placebo, non-treatment, or conventional treatment. Two researchers independently performed the document screening and selection, data extraction, and risk of bias assessment. A random-effect model was used to pool the data.
RESULTS
From a total of 11 studies that met the inclusion criteria, four studies administered through topical application and seven by oral intake. Nine studies recruited only females. Ten studies had parallel-group design, while one adopted cross-over design. The oral intake of reduced pain severity non-significantly (standardized mean difference (SMD) = -0.55, 95% CI: -1.27-0.17; 0.132). However, the topical application of this treatment had no pain-alleviating effect (SMD = 0.10, 95% CI: -0.75-0.96; 0.814). One study reported mild allergic rhinitis as an adverse effect of the treatment. Risk of bias assessment revealed that three of the eleven studies had good methodological quality, six had fair quality, and two were of poor quality.
CONCLUSIONS
This systematic review and meta-analysis suggests that the oral intake of may have a non-significant alleviating effect on acute pain severity in adults. However, its topical application has not shown pain-alleviating effect. More robust randomized controlled trials are needed for accurate estimation of the effects of oral and topical use of on the severity of different types of acute pain in adults.

Meta-Analysis Review
BACKGROUND
Nasal nitric oxide (nNO) levels in allergic rhinitis (AR), healthy people or nonallergic rhinitis (NAR) have shown contradicting results in previous studies. By meta-analysis, we reviewed studies that measured nNO in AR patients to assess nNO's ability to discriminate AR from healthy people or NAR.
METHODS
We systematically searched PubMed, Cochrane, Embase, Ovid, Web of Science, Wanfang Data, CNKI until December 15, 2020. Differences were expressed as standardized mean differences (SMD) with 95% confidence interval (CI), by random-effects method.
RESULTS
A total of 10 original studies with 561 AR patients, 327 healthy controls, 123 NAR patients were included in the narrative synthesis and 9 studies in the meta-analysis. nNO in AR was significantly increased compared with healthy controls (SMD: 0.989; 95% CI: 0.402, 1.576; p = .001) or NAR (SMD: 0.680; 95% CI: 0.101, 1.259; p = 0.021). However, subgroup analysis based on measuring process and patient characteristics showed that no significant differences were detected in nNO between AR patients with nasal polyps or sinusitis or marked ostial obstruction and healthy controls.
CONCLUSIONS
nNO is a potential indicator for recognizing AR. Nasal polyps, sinusitis and marked ostial obstruction should be considered before nNO is applied to detect AR.

Review
INTRODUCTION
Aerosol pollutants are known to raise the risk of development of non-communicable respiratory diseases (NCRDs) such as asthma, chronic bronchitis, chronic obstructive pulmonary disease, and allergic rhinitis. Sub-Saharan Africa's rapid pace of urbanization, economic expansion, and population growth raise concerns of increasing incidence of NCRDs. This research characterizes the state of research on pollution and NCRDs in the 46 countries of Sub-Saharan Africa (SSA). This research systematically reviewed the literature on studies of asthma; chronic bronchitis; allergic rhinitis; and air pollutants such as particulate matter, ozone, NOx, and sulfuric oxide.
METHODS
We searched three major databases (PubMed, Web of Science, and Scopus) using the key words "asthma", "chronic bronchitis", "allergic rhinitis", and "COPD" with "carbon monoxide (CO)", "sulfuric oxide (SO)", "ozone (O3)", "nitrogen dioxide (NO2)", and "particulate matter (PM)", restricting the search to the 46 countries that comprise SSA. Only papers published in scholarly journals with a defined health outcome in individuals and which tested associations with explicitly measured or modelled air exposures were considered for inclusion. All candidate papers were entered into a database for review.
RESULTS
We found a total of 362 unique research papers in the initial search of the three databases. Among these, 14 met the inclusion criteria. These papers comprised studies from just five countries. Nine papers were from South Africa; two from Malawi; and one each from Ghana, Namibia, and Nigeria. Most studies were cross-sectional. Exposures to ambient air pollutants were measured using spectrometry and chromatography. Some studies created composite measures of air pollution using a range of data layers. NCRD outcomes were measured by self-reported health status and measures of lung function (spirometry). Populations of interest were primarily schoolchildren, though a few studies focused on secondary school students and adults.
CONCLUSIONS
The paucity of research on NCRDs and ambient air pollutant exposures is pronounced within the African continent. While capacity to measure air quality in SSA is high, studies targeting NCRDs should work to draw attention to questions of outdoor air pollution and health. As the climate changes and SSA economies expand and countries urbanize, these questions will become increasingly important.

Meta-Analysis
INTRODUCTION
Allergic diseases are a global public health problem. Food allergy, atopic dermatitis (AD), allergic rhinoconjunctivitis, allergic rhinitis (AR) and asthma represent the natural course of allergic diseases, also known as the "atopic march". In recent years, a large number of studies have been published on the association between greenness exposure and allergic diseases. However, systematic reviews on the association between greenness exposure and multiple allergic diseases or atopic march are lacking.
METHODS
In this study, PubMed, EMBASE, ISI Web of Science, and Scopus were systematically searched. Meta-analyses were performed if at least three studies reported risk estimates for the same outcome and exposure measures.
RESULTS
Of 2355 records, 48 studies were included for qualitative review. Five birth cohort studies, five cross-sectional studies, and one case-control study were included for asthma meta-analysis, respectively. Four birth cohort studies were included for AR meta-analysis. Our results support that exposure to a greener environment at birth reduces the risk of asthma and AR in childhood. In addition, higher greenness exposure was associated with decreased odds of current asthma in children.
DISCUSSION
There was a large heterogeneity among the included studies and most of them did not specify the vegetation type and causative allergens. Therefore the study results need to be further validated. In addition, a small number of studies evaluated the association between greenness and food allergy, AD and allergic rhinoconjunctivitis. More research is needed to strengthen our understanding of the association between greenness and allergic diseases.

Meta-Analysis
IMPORTANCE
Turbinate surgery is an effective treatment for allergic rhinitis (AR) refractory to medical treatment. However, the long-term outcomes of turbinate surgery are still unclear and have not yet been confirmed by a meta-analysis and systematic review of the literature.
OBJECTIVE
To investigate the long-term outcomes and safety of turbinate surgery in AR by performing a meta-analysis.
DATA SOURCES
MEDLINE, Embase, the Cochrane Library, and ClinicalTrials.gov were searched through April 2021.
STUDY SELECTION
Studies that analyzed turbinate surgery alone, had a follow-up period of more than 1 year, examined long-term efficacy of turbinate surgery, used current turbinate surgery methods, and were published in a peer-reviewed journal were included. Full-text reviews were performed by 2 independent reviewers. Conflicts were resolved by a third reviewer.
DATA EXTRACTION AND SYNTHESIS
Descriptive and quantitative data were extracted; weighted mean difference (WMD) was synthesized under a random-effects model. Heterogeneity was assessed using the Q statistic and the I2 metric. This study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guidelines.
MAIN OUTCOMES AND MEASURES
The long-term outcomes of turbinate surgery on subjective nasal symptoms and objective parameters.
RESULTS
Of the 3962 citations retrieved, 18 studies comprising 1411 patients were included. Findings showed significantly decreased symptom scores in nasal obstruction (WMD, 4.60, 95% CI, 3.43-5.76), rhinorrhea (WMD, 3.12; 95% CI, 1.97-4.28), sneezing (WMD, 2.64; 95% CI, 1.74-3.54), itching (WMD, 1.75; 95% CI, 1.20-2.30), and nasal resistance (WMD, 0.16; 95% CI, 0.08-0.24) and a significant increased total nasal volume (WMD, 0.96; 95% CI, 0.73-1.19). There was no significant difference in the occurrence of any complication. More than 1 year after surgery, the improvements in nasal obstruction (WMD, 5.18; 95% CI, 3.00-7.37), rhinorrhea (WMD, 3.57; 95% CI, 1.78-5.37), and sneezing (WMD, 2.95; 95% CI, 1.58-4.32) were maintained.
CONCLUSIONS AND RELEVANCE
In this systematic review and meta-analysis, turbinate surgery was associated with positive outcomes in AR and maintained the association during long-term follow-up. The rate of complications is also low. These findings can guide the preoperative counseling of patients with AR being considered for turbinate surgery.

Meta-Analysis
BACKGROUND
Several large-scale studies suggest that Bacille Calmette-Guerin (BCG) vaccination in early childhood may reduce the risk of atopic diseases, but the findings remain controversial. Here, we aimed to investigate the potential correlation between early childhood BCG vaccination and the risk of developing atopic diseases.
METHODS
Eligible studies published on PubMed, EMBASE, and Cochrane CENTRAL were systematically sourced from 1950 to July 2021. Studies with over 100 participants and focusing on the association between BCG vaccine and atopic diseases including eczema, asthma, and rhinitis were included. Preliminary assessment of methods, interventions, outcomes, and study quality was performed by two independent investigators. Odds ratio (OR) with 95% confidence interval (CI) was calculated. Random effects of the meta-analysis were performed to define pooled estimates of the effects.
RESULTS
Twenty studies with a total of 222,928 participants were selected. The quantitative analysis revealed that administering BCG vaccine in early childhood reduced the risk of developing asthma significantly (OR 0.77, 95% CI 0.63 to 0.93), indicating a protective efficacy of 23% against asthma development among vaccinated children. However, early administration of BCG vaccine did not significantly reduce the risk of developing eczema (OR 0.94, 95% CI 0.76 to 1.16) and rhinitis (OR 0.99, 95% CI 0.81 to 1.21). Further analysis revealed that the effect of BCG vaccination on asthma prevalence was significant especially in developed countries (OR 0.73, 95% CI 0.58 to 0.92).
CONCLUSION
BCG vaccination in early childhood is associated with reduced risk of atopic disease, especially in developed countries.

Review
In this study, we aim to evaluate the efficacy and safety of Guizhi Decoction associated formulas for the treatment of allergic rhinitis. A total of seven online databases were searched to collect studies published up to Feb 23, 2020. Study quality of each included article was evaluated by the Cochrane Collaboration risk of bias tool. Systematic reviews were conducted based on the Cochrane systematic review method by using RevMan 5.3 Software. Among the included trials, Guizhi Decoction associated formulas alone (or plus Western medicine, or acupoint-based therapy) were main therapies in experimental groups. Interventions in control groups include Western medicine, Guizhi Decoction associated formulas alone, Chinese patent medicine, and placebo control. Primary outcomes in this study include recovery rate, accumulative marked effective rate, accumulative effective rate, and recurrence rate. Finally, 23 trials involving 2281 participants were included. Results of systematic reviews show that Guizhi Decoction and associated formulas alone, plus Western medicine or plus acupoint-based therapies, were significantly better compared with using Western medicine alone in terms of efficacy. In addition, the formulas plus nasal TCM fumigation therapy could improve effective rate for AR treatment compared to using the formulas alone. More types and cases of adverse events were reported in the control groups (Western medicine alone), but events of included trials were all mild and did not need specific medical intervention. More RCTs of high quality, and large sample size, with appropriate blinding methods or nonblinded pragmatic trials of Guizhi Decoction and associated formulas for AR are needed.
